As shown in fig. 1, in one embodiment, a composite paste processing apparatus is provided, which includes a dividing mechanism 100 and a feeding mechanism 200. In this way, the feeding mechanism 200 is used to convey the composite tape 10, so as to convey the composite tape 10 to the dividing mechanism 100 for cutting, and further process the composite tape meeting the use requirement.

The dividing mechanism 100 includes a rotating member 110 capable of rotating around a central axis, a first cutting member 120 connected to the rotating member 110, and a second cutting member 130 connected to the rotating member 110, the second cutting member 130 and the first cutting member 120 are arranged at an interval, and a linear velocity of a blade of the second cutting member 130 is the same as a linear velocity of a blade of the first cutting member 120; the feeding mechanism 200 is used for conveying the composite tape 10 to the first cutting member 120 and the second cutting member 130 for cutting; when the rotating member 110 rotates, the feeding speed of the feeding mechanism 200 is adjustable, so that the feeding length from the first cutting member 120 to the second cutting member 130 after cutting is the same as or approximately the same as the feeding length from the second cutting member 130 to the first cutting member 120 after cutting.

In the composite tape processing apparatus of the above embodiment, when the composite tape is processed, the feeding mechanism 200 is used to feed the composite tape 10 to the dividing mechanism 100, the rotating member 110 is used to rotate the first cutting member 120 and the second cutting member 130, the composite tape 10 is cut by the first cutting member 120 and the second cutting member 130, thereby obtaining two pieces of compound paste, compared with the traditional two pieces of compound paste prepared by adopting two sets of compound paste processing devices, the two pieces of compound paste can be prepared by only adopting the rotating piece 110 to drive the first cutting piece 120 and the second cutting piece 130 to rotate, thereby reducing the processing procedures, improving the processing efficiency, reducing the purchasing cost of the processing device, and further, the processing cost of the composite paste is reduced, the production space is saved, the length of a production line is shortened, and the installation difficulty and the subsequent maintenance difficulty are reduced. In the rotation process of the rotating member 110, the process from the cutting of the first cutting member 120 to the cutting of the second cutting member 130 means that the first cutting member 120 cuts the composite tape 10 by a first knife, and then the second cutting member 130 cuts the composite tape 10 by a second knife, so as to obtain a first composite sticker; the process from the cutting of the second cutting member 130 to the cutting of the first cutting member 120 refers to a process in which the second cutting member 130 cuts the composite tape 10 with a second knife and then the first cutting member 120 cuts the composite tape 10 with a third knife, thereby obtaining the second composite tape. Meanwhile, as the feeding speed of the feeding mechanism 200 can be flexibly adjusted, the feeding mechanism 200 is operated at the first feeding speed in the process from the first knife cutting of the first cutting member 120 to the second knife cutting of the second cutting member 130, and the feeding mechanism 200 is operated at the second feeding speed in the process from the second knife cutting of the second cutting member 130 to the third knife cutting of the first cutting member 120, so that the feeding lengths of the two adjacent cutting processes are the same or approximately the same, the prepared composite paste is ensured to have the same or approximately the same length, and the use requirements are met.

It should be noted that the approximately same feed length and the approximately same length of the two composite tapes in the two processes are considered to be the same within an error tolerance range in consideration of the actual influence of errors such as assembly errors and machining errors. For example, the difference between the feed lengths in the two processes may be considered the same when it is 0mm to 1mm, and the difference between the lengths in the two composite patches may be considered the same when it is 0mm to 1 mm.

The rotating member 110 can be in the form of a turntable, a rotating shaft and the like, and is rotated by a motor or a gear drive mode, so that the first cutting member 120 and the second cutting member 130 can be driven to rotate around the corresponding rotating shaft, and then the composite tape 10 can be cut. First cutting member 120 and second cutting member 130 can all be installed on rotating the piece 110 through modes such as welding, joint or grafting, only need guarantee that the installation is firm and can cut compound subsides material area 10. The first cutting member 120 and the second cutting member 130 are each preferably in the form of a cutter, and the composite tape 10 is cut by a blade of the cutter.

The adjustment of the feeding speed can flexibly select the more practical cutting condition, and only the feeding length in the two adjacent cutting processes is required to be the same or approximately the same, so that the composite pastes with the same or approximately the same length can be prepared.

As shown in fig. 1, in one embodiment, the linear velocity of the blade edge of the first cutting member 120 is the same as the linear velocity of the blade edge of the second cutting member 130. In this way, the rotation path of the blade of the first cutting member 120 and the rotation path of the blade of the second cutting member 130 can be overlapped, which facilitates the adjustment of the feeding speed of the feeding mechanism 200 to achieve the same feeding length. As shown in fig. 1, a straight line from the blade of the first cutting element 120 to the rotation center of the rotation element 110 is a first straight line 140, a straight line from the blade of the second cutting element 130 to the rotation center of the rotation element 110 is a second straight line 150, an included angle between the first straight line 140 and the second straight line 150 is a first included angle (shown as α in fig. 1) and a second included angle, the first included angle is smaller than the second included angle, and the first included angle and the second included angle are mutually combined. After the first cutting member 120 cuts the material, when the second cutting member 130 rotates through the first included angle, the feeding mechanism 200 performs an accelerated motion, and after the second cutting member 130 cuts the material, when the second cutting member 130 rotates through the second included angle, the feeding mechanism 200 performs a uniform motion, and a feeding length of the accelerated motion is the same as or approximately the same as a feeding length of the uniform motion. Thus, after the first cutting element 120 cuts the composite tape 10 by the first knife until the second cutting element 130 cuts the composite tape 10 by the second knife, the central angle of the area where the second cutting element 130 rotates is the first included angle; after the second cutter 130 cuts the composite tape 10 by the second knife, until the first cutter 120 cuts the third knife of the composite tape 10 by the second cutter 130, a central angle of an area where the second cutter 130 rotates is a second included angle. Because the first included angle is less than the second included angle, the rotating speed of the rotating part 110 is unchanged, when the first composite paste is prepared, the feeding mechanism 200 takes accelerated motion to accelerate feeding, and when the second composite paste is prepared, the feeding mechanism 200 takes uniform motion to normally feed at a uniform speed, so that the feeding lengths of two times can be the same or approximately the same, and further the lengths of the two composite pastes can be the same or approximately the same.

It should be understood that the first angle and the second angle can enclose a complete 360 ° central angle, for example, the first angle is 36 ° and the second angle is 324 °. The acceleration motion of the feeding mechanism 200 may be uniform acceleration or variable acceleration motion, and it is only necessary to provide the composite tape 10 with a preset length in the process from the time when the first cutting element 120 cuts the composite tape 10 for the first time to the time when the second cutting element 130 cuts the composite tape 10 for the second time.

As shown in fig. 3, when the coordinate system of the feeding speed and the time of the feeding mechanism 200 is established, the area a is the feeding length at the time of constant feeding, the area B is the feeding length at the time of accelerated feeding, and the area of the area a is equal to the area of the area B, that is, the feeding length at the time of constant feeding is equal to the feeding length at the time of accelerated feeding.

Further, the size of the first included angle is adjustable. So, through the size that changes first contained angle to the size of second contained angle has also been adjusted correspondingly, and then can adapt to the cutting requirement of the compound subsides of different length. The size of the first included angle can be adjusted by adjusting the installation position of the first cutting member 120 or the second cutting member 130 on the rotation member 110. So, can adopt the mode of can dismantling the connection such as joint, screw connection with first cutting piece 120 and second cutting piece 130 to be connected, be convenient for adjust the size in order to adjust first contained angle to mounted position.

As shown in fig. 1, on the basis of any of the above embodiments, the composite tape processing apparatus further includes a pressing member 300, the pressing member 300 is disposed at a distance from the rotating member 110, and the pressing member 300 can cooperate with the rotating member 110 to form a feeding channel (not labeled) for pressing the composite tape 10 and allowing the composite tape 10 to pass through. Thus, the relative interval arrangement of the pressing piece 300 and the rotating piece 110 is utilized, so that the problem of slippage of the composite tape 10 in the conveying and cutting processes can be avoided, the composite tape can be accurately cut, the accuracy of the feeding length can be ensured, the length of the prepared composite tape can be ensured to meet the use requirement, and the consistency is good. The pressing member 300 may be correspondingly configured as a rotary disc or a rotary shaft, and only needs to be matched with the rotating member 110 to press the composite tape 10 without affecting the transportation and cutting of the composite tape 10.

As shown in fig. 1 and fig. 2, on the basis of any of the above embodiments, the composite tape processing apparatus further includes a buffer mechanism 400 for buffering the composite tape 10, and the buffer mechanism 400 is disposed between the feeding mechanism 200 and the unwinding mechanism. Thus, the composite tape 10 can be buffered by the buffer mechanism 400, so as to adapt to the change of the feeding speed of the feeding mechanism 200, and prevent the composite tape 10 from breaking. For example, the composite tape 10 can be prevented from being unable to follow up quickly when the feeding mechanism 200 is moving at an accelerated speed, and the composite tape 10 is prevented from being broken due to a pulling force.

Specifically, as shown in fig. 1, the caching mechanism 400 includes a swinging member 410, a supporting member 420, and a first tensioning member 430. The supporting member 420 is rotatably connected to the swinging member 410 by a rotating shaft, a hinge, or the like, and the supporting member 420 can divide the swinging member 410 into a first swinging body 411 disposed near the feeding mechanism 200 and a second swinging body 412 disposed near the unwinding mechanism. The length of the first swinging body 411 is longer than that of the second swinging body 412, and the first tensioning member 430 is disposed below the second swinging body 412. As shown in fig. 2, the composite tape 10 can sequentially pass through the end 4121 of the second swinging body 412, the first tensioning member 430 and the end 4111 of the first swinging body 411. Thus, when the feeding mechanism 200 performs an accelerated feeding operation, the swinging member 410 rotates around the rotation axis of the connection portion with the supporting member 420, such that the one end 4111 of the first swinging member 411 rises and the one end 4121 of the second swinging member 412 falls, and the one end of the second swinging member 410 moves toward the first fastening member 430, and the composite tape 10 between the one end of the second swinging member 410 and the first fastening member 430 is released, such that the feeding of the composite tape 10 can be adapted to the accelerated feeding operation of the feeding mechanism 200, and the composite tape 10 is prevented from being torn off. When the feeding mechanism 200 performs a constant speed feeding, the swinging member 410 rotates around the rotation axis of the connection portion with the supporting member 420, so that the one end 4111 of the first swinging member 411 descends and the one end 4121 of the second swinging member 412 ascends, so that the one end of the second swinging member 410 moves away from the first tensioning member 430, thereby tightening the composite tape 10 and buffering the composite tape 10 between the one end of the second swinging member 410 and the first tensioning member 430 for releasing at the next acceleration.

As shown in fig. 1 and fig. 2, further, the buffer mechanism 400 further includes a second tensioning member 440 disposed below the second swinging body 412, the second tensioning member 440 is disposed between the second swinging body 412 and the unwinding mechanism, the second tensioning member 440 and the first tensioning member 430 are disposed at an interval, and the composite tape 10 can sequentially pass through the second tensioning member 440, an end 4121 of the second swinging body 412, the first tensioning member 430 and an end 4111 of the first swinging body 411. Thus, when the feeding mechanism 200 performs an accelerated feeding operation, the swinging member 410 rotates around the rotation axis of the connection portion with the supporting member 420, such that the end 4111 of the first swinging member 411 rises and the end 4121 of the second swinging member 412 descends, such that the end of the second swinging member 410 moves toward the first tensioning member 430 and the second tensioning member 440, and the composite tape 10 between the end of the second swinging member 410 and the first tensioning member 430 and the composite tape 10 between the end of the second swinging member 410 and the second tensioning member 440 are released, such that the feeding of the composite tape 10 can better adapt to the accelerated feeding of the feeding mechanism 200, and the composite tape 10 is prevented from being torn off. When the feeding mechanism 200 performs a constant speed feeding, the swinging member 410 rotates around the rotation axis of the connection portion with the supporting member 420, so that the one end 4111 of the first swinging member 411 descends and the one end 4121 of the second swinging member 412 ascends, and the one end of the second swinging member 410 moves away from the first tensioning member 430 and the second tensioning member 440, thereby tightening the composite tape 10 and buffering the composite tape 10 between the one end of the second swinging member 410 and the first tensioning member 430 and between the one end of the second swinging member 410 and the second tensioning member 440, so as to buffer more composite tapes 10.

Preferably, the first tensioning member 430 and the second tensioning member 440 are disposed at the same horizontal plane, and one end of the second swinging member 410 is disposed between the first tensioning member 430 and the second tensioning member 440. The composite tape 10 can be tightened after passing through the second tensioning member 440, one end of the second swinging member 410 and the first tensioning member 430, so that slipping of the composite tape 10 in the conveying process is avoided, the buffered composite tape 10 can be released well, and interference is avoided.

As shown in fig. 1 and 2, in one embodiment, the buffer mechanism 400 further includes an auxiliary driving member 450, the auxiliary driving member 450 is connected to the swinging member 410, and the auxiliary driving member 450 is used for driving the swinging member 410 to rotate around the connection portion between the supporting member 420 and the swinging member 410. So, utilize auxiliary drive piece 450 can the auxiliary drive swing piece 410 to rotate to make compound subsides material area 10 can be more quick release, thereby the accelerated feeding needs of better adaptation feeding mechanism 200 also make compound subsides material area 10 can be faster tighten, avoid appearing the problem that compound subsides material area 10 skidded at the feeding stage at the uniform velocity of feeding mechanism 200, guarantee the stability and the reliability of feed. The auxiliary driving member 450 may be configured as an air cylinder or a hydraulic cylinder, and a push rod of the air cylinder or the hydraulic cylinder is welded or clamped with the swinging member 410 (preferably, the push rod is connected with the first swinging body 411, and has a sufficient installation space, and will not affect the operation of the first tensioning member 430 and the second tensioning member 440), and drives the swinging member 410 to rotate around a corresponding axis when the push rod is moved telescopically.

It should be noted that the swinging member 410 may be configured as a rod or a column, and the supporting member 420 may be configured as a supporting post or a supporting bar. The first tensioning member 430 and the second tensioning member 440 may be provided in the form of tensioning rollers or tensioning pulleys. Meanwhile, in order to ensure that the composite tape 10 can smoothly run, corresponding rollers or pulleys may be disposed at the one end 4111 of the first oscillating body 411 and the one end 4121 of the second oscillating body 412 for the composite tape 10 to pass through and to be tensioned. The uncoiling mechanism can comprise a material tray 500 wound with the composite material sticking belt 10, and the rotary material feeding of the material tray 500 can be carried out by utilizing the power of the material feeding mechanism 200 and can also be actively rotated to carry out material feeding; the trays 500 may be two, one for supply and one for standby.

The feeding mechanism 200 can be implemented by a feeding roller wheel rotating mode or a feeding chain wheel traction mode for supplying the composite tape 10, and only needs to supply the composite tape 10 and adjust the feeding speed.
