Referring to fig. 1, an embodiment of the present invention provides a roll changing apparatus, which includes an unwinding assembly 10, a roll changing assembly 20, a cutting assembly 30, and an end pressing assembly 40.

Unreel subassembly 10 and be used for unreeling output work material area and reserve material area downstream, that is to say, unreel subassembly 10 and unreel the output and all can regard as the material area of work material area and reserve material area two, when one of them material area was as the work material area, another material area then regard as reserve material area wherein.

The reel changing assembly 20 is disposed downstream of the unwinding assembly 10, and has a reel changing passage a through which the working tape and the standby tape pass. The reel change assembly 20 is configured to controllably compress the working material tape and the backup material tape within the reel change passage a such that portions of the working material tape and the backup material tape within the reel change passage a are adhered to each other. A cutting assembly 30 is arranged upstream of the change assembly 20 for cutting the strip of work material pressed by the change assembly 20 by the input of the change channel a.

The end pressing assembly 40 is arranged downstream of the reel change assembly 20 and comprises a first pressing mechanism 41, a second pressing mechanism 42 and a supporting mechanism 43. The first pressing mechanism 41 and the second pressing mechanism 42 form a pressing passage b (see fig. 2) between which the working tape and the spare tape pass through. The support mechanism 43 can be controllably extended into or retracted from the pressing passage b.

When the supporting mechanism 43 extends into the pressing channel b, the first pressing mechanism 41 or the second pressing mechanism 42 can be controlled to press the standby material tape onto the supporting mechanism 43, and cut off the standby material tape pressed onto the supporting mechanism 43. When the supporting mechanism 43 exits the pressing channel b, the first pressing mechanism 41 or the second pressing mechanism 42 can be controlled to move, and the cut end of the spare tape in the pressing channel b and the working tape are pressed and fixed between the first pressing mechanism 41 and the second pressing mechanism 42, so that the cut end of the spare tape is bonded with the working tape.

In the roll changing device, the working material belt sequentially passes through the roll changing channel a and the pressing channel b and is conveyed downstream. In the preparation of the stock, the reserve tape is first drawn through the change channel a and along the second hold-down mechanism 42 through the hold-down channel b. Then, the control support mechanism 43 is extended into the pressing passage b. Then, the second pressing mechanism 42 is controlled to press the spare tape against the supporting mechanism 43, and the spare tape is cut off.

When changing the roll, the roll changing assembly 20 compresses the working material tape and the standby material tape in the roll changing passage a, so that the portions of the working material tape and the standby material tape in the roll changing passage a are adhered to each other. The cutting assembly 30 cuts the strip of work material at the input of the change channel a. Then, the second pressing mechanism 42 is controlled to be separated from the supporting mechanism 43 to release the pressing of the spare tape. Then, the supporting mechanism 43 is controlled to exit the pressing passage b, and at this time, the cut-off portion of the spare tape can be removed, and the cut-off end of the spare tape (i.e., the leading end of the spare tape that passes through the reel changing passage a) is located on the second pressing mechanism 42. Then, the first pressing mechanism 41 is controlled to move towards the second pressing mechanism 42, so as to press the cut end of the spare tape and the working tape onto the second pressing mechanism 42, and the cut end of the spare tape is bonded with the working tape. Finally, the first pressing mechanism 41 is controlled to move away from the second pressing mechanism 42 to reset, and the reel changing assembly 20 is controlled to release the pressing of the working tape and the standby tape. At this time, the backup tape may be transported downstream along with the working tape, that is, the backup tape output from the unwinding assembly 10 is converted into the working tape.

At this time, the used material roll on the unwinding assembly 10 can be replaced by a new material roll, and the material belt at the unwinding position of the new material roll is used as a standby material belt, and the material preparation is performed. I.e. pulls the reserve tape through the change channel a and along the first pressing means 41 through the pressing channel b. Then, the control support mechanism 43 is extended into the pressing passage b. Then, the first pressing mechanism 41 is controlled to press the backup tape against the supporting mechanism 43 and cut the backup tape to prepare for the next reel change. The next roll change process is similar to the above process, and therefore will not be described herein.

Therefore, the roll changing device can realize automatic switching (namely automatic roll changing) of the working material belt and the standby material belt, and can utilize the end part pressing assembly 40 to press and bond the cut end of the standby material belt and the working material belt in the roll changing process, so that the standby material belt and the working material belt are firmly bonded, and the phenomenon that the standby material belt and the working material belt fall off due to the fact that the cut end of the standby material belt is easily bonded on the roller in the subsequent tape feeding process is avoided.

It should be noted that the working material belt refers to the material belt which is output from the unwinding assembly 10, passes through the reel changing channel a and the pressing channel b in sequence, and is conveyed downstream. The standby tape refers to a tape which is output from the unwinding assembly 10, passes through the reel changing passage a, further passes through the pressing passage b along the first pressing mechanism 41 or the second pressing mechanism 42, and is not conveyed downstream. It can be understood that after the automatic roll changing, the standby material belt is changed into the working material belt and conveyed to the downstream, and the new material roll is changed to release the rolled material belt as the standby material belt.

It should be noted that the working tape and the spare tape may be adhesive tapes, so that the working tape and the spare tape pressed by the reel changer 20 may be adhered to each other, and the cut ends of the working tape and the spare tape pressed by the first pressing mechanism 41 and the second pressing mechanism 42 may also be adhered to each other during the reel change. Of course, in other embodiments, other types of tapes are possible, and the connection between the working tape and the standby tape is realized by adhering a double-sided adhesive tape on the standby tape, which is not limited herein.

In a specific embodiment, the roll changer includes a first state and a second state. When the supporting mechanism 43 extends into the pressing channel b in the first state of the roll changing device, the first pressing mechanism 41 is controlled to press the standby material belt onto the supporting mechanism 43, and cut off the standby material belt pressed onto the supporting mechanism 43. When the supporting mechanism 43 exits the pressing channel b, the second pressing mechanism 42 is controlled to move close to the first pressing mechanism 41, and presses the cut end of the standby material tape and the working material tape in the pressing channel b onto the first pressing mechanism 41.

When the roll changing device is in the second state and the supporting mechanism 43 extends into the pressing channel b, the second pressing mechanism 42 is controlled to press the standby material belt onto the supporting mechanism 43 and cut off the standby material belt pressed onto the supporting mechanism 43. When the supporting mechanism 43 exits the pressing channel b, the first pressing mechanism 41 is controlled to move close to the second pressing mechanism 42, and presses the cut end of the standby material tape and the working material tape in the pressing channel b against the second pressing mechanism 42.

Thus, when the standby material belt passes through the pressing passage b along the first pressing mechanism 41 and the working material belt passes through the pressing passage b between the standby material belt and the second pressing mechanism 42, the roll changing device performs the roll changing operation in the first state. When the standby material belt passes through the pressing channel b along the second pressing mechanism 42 and the working material belt passes through the pressing channel b between the standby material belt and the first pressing mechanism 41, the roll changing device performs the roll changing operation in the second state.

Specifically, in the embodiment, the reel changer further includes a mounting substrate 50, and the unwinding assembly 10, the reel changing assembly 20, the cutting assembly 30 and the end pressing assembly 40 are all mounted on the mounting substrate 50, so that the integration of each mechanism of the reel changer is improved, the size is reduced, and the space required to be occupied is saved.

In an embodiment of the present invention, the unwinding assembly 10 includes a first unwinding mechanism 11 and a second unwinding mechanism 12, and the first unwinding mechanism 11 and the second unwinding mechanism 12 are disposed on the mounting substrate 50. The first unwinding mechanism 11 is used for unwinding the tape to the reel changing assembly 20 and outputting the tape which can be used as a working tape and a standby tape. The second unwinding mechanism 12 is used for unwinding the tape, which can be used as the working tape and the standby tape, to the reel changing assembly 20. That is to say, when the first unwinding mechanism 11 unwinds the output material tape as the working material tape, the second unwinding mechanism 12 unwinds the output material tape as the standby material tape; when the first unwinding mechanism 11 unwinds the output material tape as a spare material tape, the second unwinding mechanism 12 unwinds the output material tape as a working material tape.

It should be noted that, the specific structures of the first unwinding mechanism 11 and the second unwinding mechanism 12 may adopt an unwinding structure in the prior art, as long as the continuous unwinding of the output material tape can be achieved, and the specific structures are not limited herein.

Referring to fig. 2 and 3, in the embodiment of the invention, the first pressing mechanism 41 includes a first driving member 411, a first moving seat 412, a first pressing block 413 and a first cutting knife 414. The first driving member 411 is drivingly connected to the first movable base 412 to drive the first movable base 412 to move toward or away from the second pressing mechanism 42. The first pressing block 413 and the first cutting blade 414 are disposed on the first movable base 412 to move with the first movable base 412.

When the first moving seat 412 approaches the second pressing mechanism 42, the first pressing block 413 is driven to press the spare tape onto the supporting mechanism 43, and the first cutter 414 is driven to cut off the spare tape; or, when the first moving seat 412 approaches the second pressing mechanism 42, the first pressing block 413 is driven to press the cut ends of the working tape and the standby tape onto the second pressing mechanism 42.

Alternatively, the first driver 411 may employ an air cylinder. When the supporting mechanism 43 extends into the pressing channel b, the distance between the first pressing block 413 and the supporting mechanism 43 is small, generally several millimeters, and is far smaller than the distance between the first pressing block 413 and the second pressing mechanism 42. In this way, in the process that the cylinder drives the first pressing block 413 to move towards the second pressing mechanism 42, if the supporting mechanism 43 extends into the pressing channel b, the first pressing block 413 is blocked, so that the first pressing block 413 abuts against the supporting mechanism 43, and the spare material tape is pressed against the supporting mechanism 43 and cut off by the first cutter 414; if the supporting mechanism 43 does not extend into the pressing channel b, the first pressing block 413 cannot be blocked, so that the first pressing block 413 moves to abut against the second pressing mechanism 42, and the standby material belt and the working material belt are pressed against the second pressing mechanism 42.

In an embodiment, the first pressing mechanism 41 further includes a first elastic member 415, the first pressing block 413 is movably connected to the first moving seat 412, and opposite ends of the first elastic member 415 are respectively abutted against the first pressing block 413 and the first moving seat 412, so as to provide a pre-tightening force for moving the first pressing block 413 toward the second pressing mechanism 42 relative to the first moving seat 412. The first pressing block 413 has a first escape groove (not shown) through which the first cutter 414 passes. In this way, during the material preparation process, the standby material belt is drawn to pass through the pressing channel b along the first pressing block 413, and the supporting mechanism 43 is controlled to extend into the pressing channel b. The first driving member 411 drives the first moving seat 412 to move toward the second pressing mechanism 42, and first the first pressing block 413 presses the spare tape onto the supporting mechanism 43 (compresses the first elastic member 415), and as the first moving seat 412 continues to move toward the second pressing mechanism 42 (continues to compress the first elastic member 415), the first cutting knife 414 passes through the first avoiding slot of the first pressing block 413, and then the spare tape pressed onto the supporting mechanism 43 by the first pressing block 413 is cut off. When the pressing of the spare tape needs to be released, the first driving member 411 drives the first moving seat 412 to move away from the second pressing mechanism 42, the first cutting knife 414 firstly exits the first avoiding slot along with the movement of the first moving seat 412, and then moves along with the continued movement of the first moving seat 412 away from the second pressing mechanism 42, so as to drive the first pressing block 413 to be separated from the supporting mechanism 43 until the first pressing block returns to the initial position.

In an embodiment, the first pressing mechanism 41 further includes a first guiding rod 416, the first guiding rod 416 is slidably connected to the first moving seat 412, and an end of the first guiding rod 416 facing the second pressing mechanism 42 is fixedly connected to the first pressing block 413, so that the sliding of the first guiding rod 416 relative to the first moving seat 412 is utilized to guide the movement of the first pressing block 413, so that the pressing of the first pressing block 413 is more stable and reliable. Further, the first movable base 412 has a first guide hole (not shown), the first guide rod 416 is slidably fitted in the first guide hole, and a first limit block 4161 is connected to an end of the first guide rod 416 facing away from the second pressing mechanism 42, and the first limit block 4161 is configured to prevent the first guide rod 416 from being disengaged from the first guide hole. One end of the first guide rod 416 facing the second pressing mechanism 42 is fixedly connected with the first pressing block 413, so that the first pressing block 413 and the first guide rod 416 move synchronously. Alternatively, the first elastic element 415 may be a spring and is sleeved on the first guiding rod 416.

Specifically, in the embodiment, the downstream end of the first pressing block 413 is provided with a first roller 4131. In this way, when the first driving element 411 drives the first moving seat 412 to move towards the second pressing mechanism 42, the working material tape passes around the first roller 4131 during the process that the first pressing block 413 presses the working material tape towards the second pressing mechanism 42, so as to prevent the downstream end of the first pressing block 413 from scratching the working material tape.

It will be understood that the upstream and downstream and the upstream and downstream ends are referred to herein with respect to the direction of travel of the strip of material. That is, the position where the tape passes first is the upstream or upstream end, and the position where the tape passes second is the downstream or downstream end.

In an embodiment, the mounting substrate 50 is provided with a first guide rail (not shown), and the first moving base 412 is slidably disposed on the first guide rail, so that the first guide rail is used to guide the movement of the first moving base 412 approaching to or departing from the second pressing mechanism 42, so that the pressing and cutting actions of the spare tape are stable and reliable.

In the embodiment of the present invention, the second pressing mechanism 42 includes a second driving member 421, a second moving seat 422, a second pressing block 423, and a second cutting knife 424. The second driving member 421 is drivingly connected to the second moving base 422 to drive the second moving base 422 to move toward or away from the first pressing mechanism 41. The second pressing block 423 and the second cutter 424 are disposed on the second moving base 422 to move with the second moving base 422.

When the second moving seat 422 approaches the first pressing mechanism 41, the second pressing block 423 is driven to press the standby material tape onto the supporting mechanism 43, and the second cutter 424 is driven to cut off the standby material tape; or, when the second moving seat 422 approaches the first pressing mechanism 41, the second pressing block 423 is driven to press the cut ends of the working tape and the standby tape against the first pressing mechanism 41.

Alternatively, the second driving member 421 may employ a cylinder. When the support mechanism 43 extends into the pressing channel b, the distance between the second pressing piece 423 and the support mechanism 43 is relatively small, typically several millimeters, and is much smaller than the distance between the second pressing piece 423 and the first pressing piece 413 of the first pressing mechanism 41. In this way, in the process that the cylinder drives the second pressing block 423 to move toward the first pressing block 413 of the first pressing mechanism 41, if the supporting mechanism 43 extends into the pressing channel b, the second pressing block 423 is blocked, so that the second pressing block 423 abuts against the supporting mechanism 43 to press the spare tape onto the supporting mechanism 43, and the spare tape is cut off by the second cutter 424; if the supporting mechanism 43 does not extend into the pressing channel b, the supporting mechanism 43 cannot block the second pressing block 423, so that the second pressing block 423 moves to abut against the first pressing block 413 of the first pressing mechanism 41, and the cut ends of the working tape and the standby tape are pressed against the first pressing block 413 of the first pressing mechanism 41.

In a specific embodiment, the second pressing mechanism 42 further includes a second elastic member 425, the second pressing block 423 is movably connected to the second moving seat 422, and opposite ends of the second elastic member 425 are respectively abutted to the second pressing block 423 and the second moving seat 422, so as to provide a pre-tightening force for moving the second pressing block 423 relative to the second moving seat 422 toward the first pressing block 413 of the first pressing mechanism 41. The second pressing block 423 has a second escape groove (not shown) through which the second cutter 424 passes. In this way, during preparation of the stock, the stock belt is pulled through the pressing channel b along the second pressing block 423, and the supporting mechanism 43 is controlled to extend into the pressing channel b. The second driving member 421 drives the second moving seat 422 to move toward the first pressing mechanism 41, the second pressing block 423 presses the spare tape onto the supporting mechanism 43 (compresses the second elastic member 425), and the second moving seat 422 moves toward the first pressing mechanism 41 (continues to compress the second elastic member 425) so that the second cutting knife 424 passes through the second avoiding groove of the second pressing block 423, thereby cutting off the spare tape pressed onto the supporting mechanism 43 by the second pressing block 423. When the pressing of the spare tape needs to be released, the second driving member 421 drives the second moving seat 422 to move away from the first pressing mechanism 41, the second cutting knife 424 moves with the second moving seat 422 to exit the second avoiding slot, and the second moving seat 422 continues to move away from the first pressing mechanism 41 to drive the second pressing block 423 to separate from the supporting mechanism 43 until the second pressing block returns to the initial position.

In a specific embodiment, the second pressing mechanism 42 further includes a second guiding rod 426, the second guiding rod 426 is slidably connected to the second moving seat 422, and one end of the second guiding rod 426 facing the first pressing mechanism 41 is fixedly connected to the second pressing block 423, so that the sliding of the second guiding rod 426 relative to the second moving seat 422 is utilized to guide the movement of the second pressing block 423, so that the pressing of the second pressing block 423 is more stable and reliable. Further, the second moving base 422 has a second guide hole (not shown) in which the second guide rod 426 is slidably fitted, and a second stopper 4261 is connected to an end of the second guide rod 426 facing away from the first pressing mechanism 41, and the second stopper 4261 is used to prevent the second guide rod 426 from being removed from the second guide hole. One end of the second guide rod 426 facing the first pressing mechanism 41 is fixedly connected to the second pressing block 423, so that the second pressing block 423 and the second guide rod 426 move synchronously. Alternatively, the second elastic member 425 may be a spring and is sleeved on the second guiding rod 426.

In the specific embodiment, the downstream end of the second pressing block 423 is provided with a second roller 4241. In this way, when the second driving member 421 drives the second moving seat 422 to move toward the first pressing mechanism 41, the working material belt passes around the second roller 4241 in the process that the second pressing block 423 presses the working material belt to the first pressing block 413 of the first pressing mechanism 41, so as to prevent the downstream end of the second pressing block 423 from scratching the working material belt.

In an embodiment, the mounting substrate 50 is provided with a second guide rail (not shown), and the second moving base 422 is slidably disposed on the second guide rail, so that the second guide rail guides the movement of the second moving base 422 close to or away from the first moving base 412 of the first pressing mechanism 41, so that the pressing and cutting actions of the spare tape are stable and reliable.

It should be noted that, since the first moving seat 412 and the second moving seat 422 move closer to or away from each other in the same direction, the first guide rail and the second guide rail may be the same guide rail. Of course, in other embodiments, two guide rails extending lengthwise in the same direction may be provided as the first guide rail and the second guide rail, which is not limited herein.

Referring to fig. 2 and 3, in the embodiment of the invention, the supporting mechanism 43 includes a third driving member 431 and a supporting seat 432, and the third driving member 431 is drivingly connected to the supporting seat 432 to drive the supporting seat 432 to move into or out of the pressing channel b. Alternatively, the third driver 431 may be a cylinder.

In a specific embodiment, the support mechanism 43 further includes a mounting plate 433. The mounting plate 433 is in driving connection with the third driving element 431, and the supporting seat 432 is mounted at one end of the mounting plate 433, which faces to the pressing channel b, so that the third driving element 431 drives the mounting plate 433 and the supporting seat 432 to move together, so that the supporting seat 432 extends into or exits from the pressing channel b between the first pressing block 413 and the second pressing block 423. The mounting plate 433 is provided with a first roller 61 for passing the working material belt, so that the working material belt passing through the pressing channel b between the first pressing block 413 and the second pressing block 423 is conveyed downstream under the guiding effect of the first roller 61. Further, the first rollers 61 include at least two, and the working material belt passes through each first roller 61 in an S-shaped manner.

In the embodiment, the supporting base 432 has a first abutting portion 432a corresponding to the first pressing piece 413. When the supporting base 432 extends into the pressing channel b, the first pressing block 413 moves toward the second pressing block 423 to abut against the first abutting portion 432a, so as to press the spare tape between the first pressing block 413 and the first abutting portion 432a against the first abutting portion 432a. Further, the first abutting portion 432a is provided with a first cutter groove (not shown) corresponding to the first cutter 414, and when the spare tape is cut, the first cutter 414 penetrates through the first escape groove and then cuts into the first cutter groove, so as to ensure that the spare tape between the first pressing block 413 and the first abutting portion 432a is cut.

In the embodiment, the supporting seat 432 has a second abutting portion 432b corresponding to the second pressing piece 423. When the supporting base 432 extends into the pressing channel b, the second pressing block 423 moves toward the first pressing block 413 to abut against the second abutting portion 432b, so as to press the spare tape between the second pressing block 423 and the second abutting portion 432b against the second abutting portion 432b. Further, the second abutting portion 432b is provided with a second cutter groove (not shown) corresponding to the second cutter 424, and when the spare tape is cut, the second cutter 424 passes through the second escape groove and then cuts into the second cutter groove, so as to ensure that the spare tape between the second pressing block 423 and the second abutting portion 432b is cut.

It should be noted that, in the roll changing process, when the first pressing block 413 presses the cut ends of the working material tape and the standby material tape onto the second pressing block 423, the cut ends of the working material tape and the standby material tape are bonded to each other, at this time, the compression amount of the first elastic member 415 is controlled by using the stroke of the first driving member 411, so that the first cutter 414 does not extend out from the first avoiding groove of the first pressing block 413, and the second cutter 424 does not extend out from the second avoiding groove of the second pressing block 423, so as to avoid cutting the working material tape and the standby material tape;

when the second pressing block 423 presses the cutting end of the working material belt and the spare material belt on the first pressing block 413, the cutting end of the working material belt and the spare material belt is bonded with each other, at the moment, the compression amount of the second elastic piece 425 is controlled by the stroke of the second driving piece 421, the second cutter 424 can not be extended out of the second avoiding groove of the second pressing block 423, and the first cutter 414 can not be extended out of the first avoiding groove of the first pressing block 413 so as to avoid cutting off the working material belt and the spare material belt.

In an embodiment of the invention, the reel changer further comprises a correcting assembly (not shown) comprising a first correcting roller 60a arranged downstream of the first pressing mechanism 41 and a second correcting roller 60b arranged downstream of the second pressing mechanism 42. The first correcting roller 60a is used to position the backup tape along the first presser piece 413 through the pressing passage b to correct a skew occurring during the drawing of the backup tape. The second correcting roller 60b is used to position the backup tape along the second presser block 423 across the pressing passage b to correct a skew occurring during the drawing of the backup tape.

Of course, further, the spare tape passing through the pressing passage b along the first pressing block 413 may also be wound and fixed on the first correcting roller 60a, so that the first correcting roller 60a plays both a role of correcting the spare tape and a role of fixing the spare tape. Similarly, the spare tape passing through the pressing passage b along the second pressing block 423 may be wound around the second correcting roller 60b. So, pass along first briquetting 413 when the spare material area compresses tightly passageway b, the work material area is passed between spare material area and the second briquetting 423 and is compressed tightly passageway b, the work material area is worn out and is compressed tightly passageway b and then carry to the low reaches, the spare material area is worn out and is compressed tightly passageway b after the winding and be fixed in first correction roller 60a, thereby utilize first briquetting 413 to compress tightly the spare material area in the first butt portion 432a of supporting seat 432, and utilize first cutter 414 to cut off the spare material area, the uniformity of the size of the start end of the spare material area when guaranteeing to change the book at every turn, be favorable to improving the area effect of connecing. When the spare material area passes along second briquetting 423 and compresses tightly passageway b, the work material area is passed between spare material area and the first briquetting 413 and is compressed tightly passageway b, the work material area is worn out and is compressed tightly passageway b back and carry to the low reaches, the winding is fixed in second correction roller 60b after spare material area is worn out and is compressed tightly passageway b, thereby utilize second briquetting 423 to compress tightly spare material area in the second butt portion 432b of supporting seat 432, and utilize second cutter 424 to cut off spare material area, the uniformity of the size of the start end of spare material area when ensureing at every turn, be favorable to improving the area effect. Specifically, both the first correcting roller 60a and the second correcting roller 60b may be mounted to the mounting substrate 50.

Further, both the first correcting roller 60a and the second correcting roller 60b can be controlled to rotate around their axes. In this way, when the spare tape wound around the first correction roller 60a is cut by the first cutter 414, the first correction roller 60a rotates around its axis, so that the end of the spare tape connected to the first correction roller 60a is wound up by the first correction roller 60 a. When the spare tape wound around the second correcting roller 60b is cut by the second cutter 424, the end of the spare tape connected to the second correcting roller 60b is wound up by the second correcting roller 60b.

It should be noted that the rotation of the first correcting roller 60a around its own axis can be driven by a winding driving mechanism in the prior art, and therefore, the detailed description thereof is omitted. The rotation of the second correcting roller 60b around its own axis can be driven by a winding driving mechanism in the prior art, and therefore, it is not described in detail herein.

The second reel changer 22 is configured to be movable towards the first reel changer 21 to press the working and standby tapes against the first reel changer 21.

In this way, when the working material tape passes through the reel change passage a near the first reel change mechanism 21 and the standby material tape passes through the reel change passage a near the second reel change mechanism 22, the first reel change mechanism 21 moves toward the second reel change mechanism 22 during the reel change process, so as to press the working material tape and the standby material tape against the second reel change mechanism 22. When the working material tape passes through the reel change passage a near the second reel change mechanism 22 and the standby material tape passes through the reel change passage a near the first reel change mechanism 21, the second reel change mechanism 22 moves toward the first reel change mechanism 21 during the reel change process to press the working material tape and the standby material tape against the first reel change mechanism 21.

In one embodiment, the first reel-changing mechanism 21 includes a first pushing block 211 and a first pressing driving member 212. The first push block 211 is movably coupled to the mounting substrate 50.

Of course, the first slide rail and the first slider are not necessary, and in some embodiments, the first slide rail and the first slider may not be provided, and the first push block 211 may be directly mounted at the driving end of the first compression driving element 212.

In the embodiment, the upstream end of the first pushing block 211 is provided with a third roller 2112. In this way, when the first pushing block 211 moves towards the second reel changing mechanism 22, the working material tape passes around the third roller 2112 when the first pushing block 211 presses the working material tape to the second reel changing mechanism 22, so as to prevent the upstream end of the first pushing block 211 from scratching the working material tape.

In one embodiment, the second reel changer 22 includes a second pushing block 221 and a second pressing driving member 222. The second push block 221 is movably connected to the mounting substrate 50. The second pressing driving member 222 is mounted on the mounting substrate 50 and is in transmission connection with the second pushing block 221 to drive the second pushing block 221 to move toward the first pushing block 211 of the first reel changing mechanism 21, so as to press the working tape and the standby tape penetrating through the reel changing channel a onto the first pushing block 211 of the first reel changing mechanism 21, and further bond the working tape and the standby tape to each other. Alternatively, the second compression drive 222 may be a pneumatic cylinder.

Further, a second slide rail may be provided on the mounting substrate 50, and a second slider may be provided on the second push block 221, and the second slider is slidably fitted to the second slide rail, so as to guide the movement of the second push block 221 toward or away from the first push block 211 of the first reel changer 21.

It should be noted that, since the first pushing block 211 and the second pushing block 221 move close to or away from each other in the same direction, the first sliding rail and the second sliding rail may be the same sliding rail. Of course, in other embodiments, two sliding rails extending lengthwise in the same direction may be provided as the first sliding rail and the second sliding rail, which is not limited herein.

In particular, in the embodiment, the upstream end of the second pushing block 221 is provided with a fourth roller 2212. In this way, when the second pushing block 221 moves towards the first pushing block 211 of the first reel changer 21, the working material tape is wound around the fourth roller 2212 in the process that the second pushing block 221 presses the working material tape to the first pushing block 211 of the first reel changer 21, so as to prevent the upstream end of the second pushing block 221 from scratching the working material tape.

Referring to fig. 2 and 6, in the embodiment of the present invention, a plurality of second rollers 62 are disposed upstream of the reel change assembly 20, and the plurality of second rollers 62 are used for guiding the working tape and the standby tape into the reel change passage a. That is, the working tape and the standby tape unreeled and outputted by the unreeling assembly 10 are respectively guided into the reel changing passage a by the corresponding second passing rollers 62.

In the embodiment of the present invention, the cutting assembly 30 includes a cutting driving member 31, a cutter seat 32 and a third cutter 33. The cutting driving member 31 is drivingly connected to the cutter seat 32, the third cutter 33 is disposed on the cutter seat 32, and the cutter seat 32 moves under the driving of the cutting driving member 31, so as to drive the third cutter 33 to cut off the working material tape at the input end of the reel changing passage a.

Specifically, in the embodiment, the cutting assembly 30 further includes a third pressing block 34, the third pressing block 34 is disposed on the cutter seat 32, and the cutter seat 32 is driven by the cutting driving member 31 to move, so as to drive the third pressing block 34 to press the working material tape and the standby material tape onto the corresponding second roller 62, respectively, and drive the third cutter 33 to cut off the working material tape between the input end of the reel changing channel a and the third pressing block 34. So, third briquetting 34 compresses tightly the work material area and is fixed in the second that corresponds and crosses roller 62, and first ejector pad 211 and second ejector pad 221 compress tightly the work material area fixedly simultaneously to make the third cutter 33 all compressed tightly fixedly in the part of cutting line both sides in the work material area when cutting off the work material area, be favorable to improving cutting quality.

Further, the upstream end of the first pusher block 211 has a third cutter groove 2111 (see fig. 5). When the first pusher 211 moves toward the second pusher 221 and presses the working tape and the standby tape against the second pusher 221, the third cutter slot 2111 is aligned with the third cutter 33. At this time, when the cutter seat 32 moves toward the roll changing assembly 20, the third pressing block 34 is driven to press the working material tape and the standby material tape onto the corresponding second passing roller 62, and the third cutter 33 is driven to cut into the third cutter groove 2111 of the first pushing block 211, so as to cut off the working material tape. In this way, the third cutter slot 2111 is provided to prevent the third cutter 33 from contacting the first push block 211, which may result in damage to the third cutter 33 and the first push block 211.

Further, the upstream end of the second push block 221 has a fourth cutter groove 2211 (see fig. 5). When the second push block 221 moves toward the first push block 211 and presses the work tape and the spare tape against the first push block 211, the fourth cutter groove 2211 is aligned with the third cutter 33. At this time, the cutter seat 32 can move toward the roll-changing assembly 20, so as to drive the third pressing block 34 to press the working material tape and the standby material tape onto the corresponding second passing roller 62, and drive the third cutter 33 to cut into the fourth cutter groove 2211 of the second pushing block 221, so as to cut off the working material tape. Thus, the fourth cutter slot 2211 can prevent the third cutter 33 from contacting the second push block 221, which may damage the third cutter 33 and the second push block 221.

In an embodiment, the cutting assembly 30 further includes a third elastic member 36, and opposite ends of the third elastic member 36 abut between the third pressing block 34 and the cutter seat 32 to provide a pre-tightening force for moving the third pressing block 34 relative to the cutter seat 32 toward the reel changer 20. So, when cutting, cut driving piece 31 drive cutter seat 32 and move towards roll change subassembly 20, third briquetting 34 at first offsets with the second that corresponds crosses roller 62 to compress tightly respectively with work material area and reserve material area and be fixed in the second that corresponds and cross roller 62, along with cutter seat 32 continues to move towards roll change subassembly 20 (continues to compress third elastic component 36), make third cutter 33 and the contact of work material area, and then cut off the work material area. That is, when cutting, the third pressing block 34 presses the work material tape, and then the third cutter 33 cuts the work material tape.

Further, the cutter seat 32 has a third guiding hole (not shown), the third guiding rod 35 is slidably fitted in the third guiding hole, and a third limiting block 351 is connected to an end of the third guiding rod 35 facing away from the reel changing assembly 20, and the third limiting block 351 is used for preventing the third guiding rod 35 from being disengaged from the third guiding hole. One end of the third guide rod 35 facing the reel change assembly 20 is fixedly connected with the third pressing block 34, so that the third pressing block 34 and the third guide rod 35 move synchronously. Alternatively, the third elastic element 36 may be a spring and is sleeved on the third guiding rod 35.

The operation of the reel changer of the present invention will be described with reference to the accompanying drawings:

taking the material belt unreeled and output by the first unreeling mechanism 11 as a working material belt and the material belt unreeled and output by the second unreeling mechanism 12 as a standby material belt as an example, the working material belt sequentially passes through the reel changing channel a and the compressing channel b and is conveyed downstream by passing through the first passing roller 61.

The material preparation process comprises the following steps: first, the standby material belt is drawn to pass through the reel change passage a along the second pushing block 221 (i.e., to pass through the reel change passage a from between the working material belt and the second pushing block 221), and pass through the pressing passage b along the second pressing block 423 (i.e., to pass through the pressing passage b from between the working material belt and the second pressing block 423), and then wound on the second correcting roller 60b.

Then, the third driving member 431 drives the supporting seat 432 to move leftward to the pressing passage b between the first pressing piece 413 and the second pressing piece 423.

Then, the second driving member 421 drives the second moving seat 422 to move toward the first moving seat 412, so that the second pressing block 423 presses the spare tape onto the second abutting portion 432b of the supporting seat 432, and the second cutting blade 424 cuts off the spare tape. At this time, the cut end of the spare tape, which penetrates out of the reel change passage a, is located on the second presser 423.

And (3) a roll changing process: first, when the material roll on the first unwinding mechanism 11 is about to be used up, the first pressing driving element 212 drives the first pushing block 211 to move towards the second pushing block 221, so as to press the working material tape and the standby material tape against the second pushing block 221, so that the portions of the standby material tape and the working material tape located in the roll changing channel a are adhered to each other. At this time, the cutting driving member 31 of the cutting assembly 30 can drive the cutter seat 32 to move rightwards, so that the third pressing block 34 presses the working material tape and the standby material tape to the corresponding second passing roller 62, and the third cutter 33 cuts the working material tape. After cutting, the cutting driving member 31 can drive the cutter base 32 to move leftward and return.

After the first pushing block 211 presses the working tape and the spare tape onto the second pushing block 221, the second driving element 421 drives the second moving seat 422 to move away from the first moving seat 412, so that the second pressing block 423 is separated from the second abutting portion 432b of the supporting seat 432.

Then, the third driving member 431 drives the supporting seat 432 to move rightward, so that the supporting seat 432 exits the pressing passage b between the first pressing block 413 and the second pressing block 423. At this time, the cut portion of the backup tape (i.e., the portion connected to the second correcting roller 60b after cutting) can be removed.

Then, the first driving element 411 drives the first moving seat 412 to move toward the second moving seat 422 until the first pressing block 413 presses the cut ends of the working tape and the standby tape onto the second pressing block 423, so that the cut ends of the standby tape and the working tape are bonded to each other.

Finally, the first driving element 411 drives the first movable seat 412 to move away from the second movable seat 422 to reset, so as to release the compression on the cut ends of the working tape and the standby tape. Meanwhile, the first pressing driving member 212 drives the first pushing block 211 to move away from the second pushing block 221 and reset, so as to release the pressing of the working tape and the standby tape. At this time, the standby material tape may be conveyed downstream along with the working material tape, that is, the standby material tape unreeled and output by the second unreeling mechanism 12 is converted into the working material tape. And, the material roll on the first unwinding mechanism 11 can be replaced at this time, and the material is prepared for the next reel change. The next roll change process is similar to the above roll change process, and therefore is not described herein.

Based on the reel changing device, the invention further provides a rubberizing device, which comprises the reel changing device in any one of the embodiments. Specifically, the rubberizing equipment further comprises a glue preparation device and a rubberizing device. The glue preparation device is arranged at the downstream of the roll changing device and used for cutting the working material belt conveyed by the roll changing device into adhesive tapes with preset lengths. The adhesive tape sticking device is arranged at the downstream of the adhesive tape preparing device and is used for sticking the adhesive tape with the preset length on the surface of the pole piece.

Furthermore, the rubberizing equipment comprises two groups of reel changing devices, a glue preparing device and a rubberizing device, wherein the rubberizing device in one group is used for attaching the adhesive tape to one side surface of the pole piece, and the rubberizing device in the other group is used for attaching the adhesive tape to the other side surface of the pole piece.
