In an embodiment of the present application, the following structural design and improvement are performed with respect to the specific structural form of the hoisting module 14 in the winding machine 1, and the following description is made with reference to fig. 3 to 5.

Specifically, for the inflatable shaft 4 assembled with the new paper roll 200, the inflatable shaft 4 can be clamped by the loading fixture 142 and the inflatable shaft 4 is movably hoisted to the frame 11 for standby in cooperation with the loading assembly 141. The lifting bracket 1411 is erected on the top of the frame 11, and can drive the loading clamp 142 to reciprocate through the synchronous belt 14123 so as to realize the lifting of the inflatable shaft 4.

Further, for the loading fixture 142, for convenient hoisting of the air expansion shaft 4, the loading fixture 142 includes a hanging beam 1421, a guiding vertical rod 1422, a lifting cylinder 1423, a driving cylinder 1424, a connecting seat 1425 and a lifting hook 1426, wherein the hanging beam 1421 is slidably arranged on the hanging bracket 1411 and is connected with the synchronous belt 14123, the guiding vertical rod 1422 is vertically arranged on the hanging beam 1421, the connecting seat 1425 is slidably arranged on the guiding vertical rod 1422, the lifting cylinder 1423 is arranged between the hanging beam 1421 and the connecting seat 1425, the lifting hook 1426 is rotatably arranged on the connecting seat 1425, and the driving cylinder 1424 is hinged between the lifting hook 1426 and the connecting seat 1425.

Specifically, the loading fixture 142 can move along with the loading assembly 141 to meet the requirements of lifting and unloading the inflatable shaft 4. When the air-expanding shaft 4 is hoisted, the loading clamp 142 moves along with the synchronous belt 14123 so that the loading clamp 142 extends out of the frame 11, and then the lifting cylinder 1423 drives the connecting seat 1425 to descend, so that the lifting hooks 1426 are arranged below two end parts of the air-expanding shaft 4. The actuating cylinder 1424 is actuated to rotate the hook 1426, and the air-expanding shaft 4 is hooked by the hook 1426. The lifting cylinder 1423 drives the connecting seat 1425 to lift, then the synchronous belt 14123 drives the loading clamp 142 to reversely move, so that the air expansion shaft 4 moves to a position above the frame 11 where the air expansion shaft 4 is stored, the driving cylinder 1424 acts to reversely rotate the lifting hook 1426 to release the air expansion shaft 4, and the air expansion shaft 4 is placed on the frame 11 for standby.

Still further, in order to enable the automatic unloading of the completed roll of inflatable shaft 4 from the frame 11 with the film roll 100, the lifting module 14 further comprises an unloading assembly 143, and the lifting fixture comprises an unloading fixture 144.

The unloading assembly 143 includes a unloading driving component 1431 and a connecting shaft 1432, the unloading fixture 144 includes two lifting arms 1441, lower ends of the two lifting arms 1441 are respectively disposed at corresponding ends of the connecting shaft 1432, and a lifting clamping groove 1442 is disposed at an upper end of the lifting arm 1441; the connection shaft 1432 is rotatably provided on the frame 11, and the discharge driving part 1431 is configured to drive the connection shaft 1432 to rotate.

In the actual use process, when the reel driving module 13 drives the air expansion shaft 4 to rotate and the outer winding of the upper paper roll 200 is completed, the air expansion shaft 4 is communicated with the film roll 100 to be separated from the reel driving module 13 and supported by the lifting arms 1441, and two end parts of the air expansion shaft 4 are clamped in corresponding lifting clamping grooves 1442. At this time, the air-expanding shaft 4 and the film roll 100 are carried on the lifting arm 1441, and the connecting shaft 1432 is driven to rotate by the unloading driving part 1431, so that the lifting arm 1441 drives the air-expanding shaft 4 and the film roll 100 to move downward to realize the unloading operation.

Still further, in order to realize that the inflatable shaft 4 can automatically roll onto the lifting arm 1441 after being rolled up and separated from the reel driving module 13, two sides of the frame 11 are respectively provided with a transversely arranged sliding rail 15, the reel driving module 13 is slidably arranged on the sliding rail 15, the surface of the outer end part of the sliding rail 15 forms an inclined rail surface 151, and the inclined rail surface 151 extends obliquely downwards towards the lifting arm 1441.

Specifically, the spool driving module 13 in the conventional art realizes the rotation of the balloon shaft 4 by driving the driving gear to rotate by the motor to match with the driven gear on the balloon shaft 4. After the winding operation is completed on the air expansion shaft 4, the driving gear of the reel driving module 13 is separated from the driven gear on the air expansion shaft 4, and the air expansion shaft 4 falls on the inclined rail surface 151 after being separated from the reel driving module 13. Since the inclined rail surface 151 is an inclined surface and is inclined downwards towards the lifting arm 1441, the inflatable shaft 4 can automatically slide towards the lifting arm 1441 along the inclined rail surface 151 by means of self gravity, so that automatic coil unloading operation is achieved through the lifting arm 1441.

In another embodiment of the present application, the automatic handling device 2 needs to meet the requirements of automatic paper roll 200 removal and automatic paper roll 200 feeding of the air expansion shaft 4, and the specific structural form of the automatic handling device 2 is described with reference to fig. 6-11.

The automatic handling device 2 comprises a handling frame 21, a carriage 22, a support bracket 23, an inflation and deflation assembly 24 and a supply assembly 25. The inflation and deflation assembly 24 is arranged at one end of the loading and unloading frame 21, the inflation and deflation assembly 24 can clamp the inflatable shaft 4 unloaded from the hoisting module 14, and the inflation and deflation assembly 24 can also perform inflation and deflation operation on the inflatable shaft 4 according to the requirement.

The carriage 22 can drive the bearing piece to slide reciprocally between the inflation and deflation assembly 24 and the supply assembly 25, the bearing bracket 23 is arranged on the carriage 22 and is used for bearing the inflation shaft 4 and the film roll 100 and also is used for bearing a new paper roll 200, the supply assembly 25 comprises a supporting frame 251 and a feed box 252, the feed box 252 is used for containing the new paper roll 200, a switchable feed opening 2521 is arranged at the bottom of the feed box 252 so as to throw the new paper roll 200 through the feed opening 2521, the supporting frame 251 is arranged on the loading and unloading frame 21 and far away from the inflation and deflation assembly 24, and the feed box 252 is arranged on the supporting frame 251.

Specifically, when the inflatable shaft 4 is wound, the sliding frame 22 moves to the air charging and discharging assembly 24, the inflatable shaft 4 is communicated with the film roll 100 and is placed on the support bracket 23, and meanwhile, the air charging and discharging assembly 24 clamps the corresponding end of the inflatable shaft 4 to discharge air to the inflatable shaft 4.

After the inflatable shaft 4 is deflated, the paper roll 200 in the film roll 100 can be easily separated from the inflatable shaft 4, at this time, the sliding frame 22 moves away from the inflation and deflation assembly 24, the inflatable shaft 4 is still clamped by the inflation and deflation assembly 24, and the film roll 100 moves along the support bracket 23 and gradually separates from the inflatable shaft 4 along the axis direction of the inflatable shaft 4.

After the film roll 100 is released from the air-expanding shaft 4, the film roll 100 on the support bracket 23 can be removed from the automatic loading and unloading device 2. And bin 252 in feed assembly 25 may be opened to allow one roll 200 in bin 252 to drop down and be deposited onto support bracket 23. The support bracket 23 is moved by the carriage 22 in the direction of the inflation and deflation assembly 24 so that the paper roll 200 on the support bracket 23 is again fitted over the inflatable shaft 4. After a new paper roll 200 is sleeved on the air expansion shaft 4, the air inflation and deflation assembly 24 can perform air inflation treatment on the air expansion shaft 4, so that the new paper roll 200 is firmly tensioned on the air expansion shaft 4 for standby winding.

By configuring the inflation and deflation assembly 24 and the supply assembly 25, on one hand, the inflation and deflation assembly 24 can also inflate and deflate the inflatable shaft 4 to meet the requirements of unloading the film roll 100 and loading the new paper roll 200, on the other hand, the inflation and deflation assembly 24 can clamp the inflatable shaft 4 to meet the requirements that the inflatable shaft 4 is effectively supported and the new paper roll 200 is loaded after the film roll 100 is separated from the inflatable shaft 4, meanwhile, the sliding frame 22 drives the supporting bracket 23 to move, the supporting bracket 23 can unload the film roll 100 and move and assemble the new paper roll 200 onto the inflatable shaft 4, and further automatic loading and unloading of the inflatable shaft 4 are achieved without manual participation, the degree of automatic operation is improved, the labor intensity of workers is reduced, and the production efficiency is improved.

Further, for the inflation and deflation assembly 24, it is required to meet the requirements of inflation and deflation of the inflation shaft 4 and clamping support, for this purpose, the inflation and deflation assembly 24 includes an inflation and deflation base 241, an inflation and deflation member 242, two clamping members 243, a clamping driving member 244 and a reciprocating driving member 245, the two clamping members 243 being arranged in opposition, the clamping driving member 244 being configured to drive the two clamping members 243 to slide in opposition on the inflation and deflation base 241, the inflation and deflation member 242 being located between the two clamping members 243, the reciprocating driving member 245 being configured to drive the inflation and deflation member 242 to slide on the inflation and deflation base 241;

The inflation and deflation member 242 is provided with a first vent hole 2421 and a second vent hole 2422 which are communicated with each other, the first vent hole 2421 is arranged at the free end of the inflation and deflation member 242, and the second vent hole 2422 is configured to be connected with an inflator; wherein the inflation/deflation base 241 is provided on the loading/unloading frame 21.

Specifically, two oppositely arranged clamping members 243 disposed on the inflation/deflation base 241 are matched with each other to realize clamping and supporting on the inflatable shaft 4, and the two clamping members are driven to relatively approach or separate by a clamping driving member 244 (such as an air cylinder or an electric push rod), and both clamping members can move, or one of the clamping members is fixed, and the other clamping member moves.

After the inflatable shaft 4 and the film roll 100 are placed on the support bracket 23, the end of the inflatable shaft 4 will be located between the two clamping members, and the clamping driving member 244 drives the two clamping members to clamp the inflatable shaft 4 therebetween, so that the inflatable shaft 4 can be held and supported by the clamping member 243.

After the inflatable shaft 4 is clamped, the inflation and deflation member 242 will move toward the end of the inflatable shaft 4 to interface with the inflation and deflation holes of the inflatable shaft 4 under the drive of the reciprocating drive member 245 (e.g., a cylinder or an electric push rod). Thus, the first vent hole 2421 is communicated with the inner air cavity of the inflatable shaft 4, and the inflator connected with the second vent hole 2422 enables the second vent hole 2422 to be communicated with the outside when the inflator is not inflated, so that the inflatable shaft 4 is deflated.

When a new paper roll 200 is replaced on the inflatable shaft 4, the inflator inflates the second vent hole 2422 to enable the air cavity of the inflatable shaft 4 to be filled with air, and after the inflatable shaft 4 is inflated, the paper roll 200 is fixed on the inflatable shaft 4.

In order to improve the reliability of supporting the inflatable shaft 4, an unloading clamping plate 246 is further arranged on the inflation and deflation base 241, and a supporting groove for positioning the inflatable shaft 4 is formed in the unloading clamping plate 246.

Specifically, after the inflatable shaft 4 and the film roll 100 are placed on the support bracket 23, the end of the inflatable shaft 4 will be located between the two clamping members, and at the same time, the inflatable shaft 4 will also be clamped in the support groove of the unloading clamping plate 246. After the end of the inflatable shaft 4 is clamped by the two clamping components, the inflatable shaft 4 is further supported by the support column through the unloading clamping plates 246, so that two-point supports are formed on the inflatable shaft 4, and the support reliability of the inflatable shaft 4 is improved.

Correspondingly, the air expansion shaft 4 can be provided with an annular positioning groove 45 matched with the unloading clamping plate 246, so that the unloading clamping plate 246 can be clamped in the annular positioning groove 45 to limit the air expansion shaft 4 in the axial direction.

Further, in order to improve the clamping reliability of the inflatable shaft 4, a clamping groove (not marked) is formed on the clamping component, and a clamping space is formed between the two clamping grooves; after the inflatable shaft 4 is clamped by the two clamping parts, the inflatable shaft 4 is positioned in the two clamping grooves.

Specifically, when the inflatable shaft 4 is clamped by the clamping component, in order to effectively position the inflatable shaft 4, a clamping groove can be formed in the clamping component, the outline of the clamping groove is matched with the outline of the inflatable shaft 4, and the inflatable shaft 4 is clamped in the clamping groove, so that the inflatable shaft 4 can be accurately positioned and effectively clamped and supported.

Still further, the support bracket 23 is formed with a support groove 231, and the cross section of the support groove 231 is in a V-shaped structure.

Specifically, the longitudinal section of the support bracket 23 is in a V-shaped structure, so that after the film roll 100 is placed on the support bracket 23, the position of the film roll 100 can be automatically positioned; and, after the paper roll 200 outputted from the feed box 252 falls onto the support bracket 23, the support bracket 23 can be positioned by the V-shaped support groove 231 formed by the support bracket, so as to ensure that the paper roll 200 can be accurately sleeved on the inflatable shaft 4.

Wherein in order to ensure that the roll 200 is nested in place during the process of telescoping the roll 200 on the inflatable shaft 4. The supporting groove 231 has two supporting surfaces which are arranged in an inclined manner, a through hole is formed in the supporting surface, a limit thimble 232 which can slide is arranged on the supporting bracket 23, and the limit thimble 232 is inserted into the corresponding through hole; the limiting pins 232 disposed on the two bearing surfaces and disposed opposite to each other are disposed obliquely to form a clamping space for clamping the paper roll 200 between the two bearing surfaces after extending out of the through hole.

Specifically, after a new paper roll 200 is put on the support bracket 23, the paper roll 200 is located between two support surfaces, and then the limiting ejector pins 232 are driven to extend through driving members such as an air cylinder, so that the paper roll 200 is clamped on the support surfaces by the two limiting ejector pins 232 which are arranged in a crossed manner. In the process of driving the paper roll 200 to move and load towards the inflatable shaft 4 through the sliding frame 22, the paper roll 200 is pressed on the bearing surface by the limiting ejector pins 232 and cannot generate displacement due to contact with the inflatable shaft 4, so that the paper roll 200 can be reliably sleeved on the inflatable shaft 4 and the requirement of assembling the paper roll 200 in place can be met.

While there are various ways in which the roll 200 may be unloaded from the support bracket 23 during actual use. For example: the support bracket 23 may be turned over by itself to effect automatic unloading of the film roll 100. Specifically, the support bracket 23 is rotatably provided on the carriage 22, and a turnover driving member 26 is provided between the support bracket 23 and the loading and unloading frame 21.

Specifically, in the actual use process, after the film roll 100 on the support bracket 23 is separated from the air expansion shaft 4, the carriage 22 drives the support bracket 23 to leave the air expansion shaft 4 at this time, the turnover driving component 26 acts to turn over the support bracket 23, and a supporting surface of the turned support bracket 23 extends obliquely downward, so that the film roll 100 rolls down from the support bracket 23 along the obliquely downward extending supporting surface by gravity, and further automatic unloading of the film roll 100 is realized.

The coil unloading is carried out in a turnover mode of the support bracket 23, so that the requirement of subsequent automatic film wrapping packaging can be met. In the case of manual intervention coil stripping, the automatic handling device 2 further comprises a transferring assembly 27, wherein the transferring assembly 27 comprises a transferring seat 271, a transferring support shaft 272 and a rotary driving part 273, the transferring support shaft 272 is transversely arranged and rotatably arranged on the transferring seat 271, and the rotary driving part 273 is configured to drive the transferring support shaft 272 to reciprocally rotate; wherein the inflation and deflation assembly 24 is arranged at one end of the loading and unloading frame 21, the transfer assembly 27 is arranged at the other end of the loading and unloading frame 21, and the transfer seat 271 is arranged on the loading and unloading frame 21.

Specifically, in the film roll 100 on the support bracket 23, there are cases where the film roll 100 does not need to be wrapped and packed due to quality problems in inspection or the film roll 100 needs to be subjected to a specific packing process manually during use. At this time, in the process of separating the film roll 100 on the support bracket 23 from the air expansion shaft 4, the transfer support shaft 272 of the transfer assembly 27, which is disposed at a different end from the air charging and discharging assembly 24 in the loading and unloading frame 21, is in a substantially coaxial state with the air expansion shaft 4. After the air expansion shaft 4 is deflated, the sliding frame 22 drives the supporting bracket 23 to move, so that the film roll 100 is separated from the air expansion shaft 4, and meanwhile, the transferring supporting shaft 272 is inserted into the paper roll 200 of the film roll 100 from the other side of the film roll 100, so that the film roll 100 is supported by the transferring supporting shaft 272.

After the film roll 100 is supported by the transferring support shaft 272, the transferring support shaft 272 is driven to rotate by the rotary driving part 273, so that the film roll 100 rotates away from the support bracket 23, and the requirement of manually unloading the film roll 100 from the transferring support shaft 272 is met. At the same time, the support bracket 23 can be emptied in time, and a new paper roll 200 is put in for later use from the upper bin 252.

Further, in order to facilitate installation of the transfer support shaft 272, a transfer support 274 is disposed on the transfer seat 271, a vertical shaft 275 is disposed between the transfer support 274 and the transfer seat 271, the transfer support shaft 272 is disposed on the vertical shaft 275, and the rotation driving part 273 is disposed on the transfer support 274 and connected to the vertical shaft 275.

Specifically, the transferring support 274 disposed on the transferring seat 271 can meet the installation requirements of the transferring support shaft 272 and the rotation driving part 273, the vertical shaft 275 disposed on the transferring support 274 can meet the requirement of horizontally rotating the transferring support shaft 272, and the rotation driving part 273 can be a rotary cylinder or a motor to drive the vertical shaft 275 to rotate so as to drive the transferring support shaft 272 to rotate.

Further, the loading and unloading frame 21 comprises a bottom frame 211 and two vertical frames 212, the bottom frame 211 is transversely arranged, the vertical frames 212 are vertically arranged and fixed at corresponding ends of the bottom frame 211, and the sliding frame 22 is positioned between the two vertical frames 212 and is slidably arranged on the bottom frame 211; the stand 212 is provided with a lifting driving part 213; the inflation/deflation base 241 is slidably disposed on the stand 212 and connected to the corresponding elevation driving member 213, and the transfer base 271 is slidably disposed on the stand 212 and connected to the corresponding elevation driving member 213.

Specifically, for both the inflation and deflation assemblies 24 and the transfer assemblies 27, the respective stands 212 can be moved up and down. Since the height position of the support bracket 23 is constant, the larger diameter of the film roll 100 makes the height of the balloon shaft 4 and the paper roll 200 higher for the placement of the film roll 100 on the support bracket 23. At this time, the inflation and deflation assembly 24 needs to be lifted correspondingly so that the end of the inflation shaft 4 can be located between the two clamping members. Meanwhile, for the transfer of the film roll 100 to the transfer support shaft 272, the transfer assembly 27 is correspondingly lifted to match the transfer support shaft 272 with the height of the paper roll 200 in the film roll 100.

Meanwhile, when a new paper roll 200 is placed on the support bracket 23 to be sleeved on the air expansion shaft 4 clamped by the air inflation and deflation assembly 24, the overall height of the air inflation and deflation assembly 24 needs to be reduced at the moment because the height of the paper roll 200 on the support bracket 23 is low, so that the height of the air expansion shaft 4 is matched with the height of the paper roll 200 on the support bracket 23. In this way, the use requirements of the inflatable shaft 4 for automatically unloading the film roll 100 and the new paper roll 200 for automatically assembling onto the inflatable shaft 4 can be met.

Still further, as for the bin 252, which stores a plurality of rolls 200, in order to meet the requirement of outputting one roll 200 through the discharge opening 2521 at a time, the bin 252 is modified as follows.

the second insert plate 2525 is located below the first insert plate 2524, and the second insert plate 2525 is configured to switch the feed opening 2521; also, the first insertion plate 2524 and the second insertion plate 2525 form a temporary storage space for accommodating a single paper roll 200 in the transport path 2523.

Specifically, the storage bins 2522 are large in volume and wide in width to accommodate a number of rolls 200, while the width of the transport channels 2523 to the bottom of the storage bins 2522 is small relative to the width of the storage bins 2522. In particular, the width of the transport path 2523 at the nip 2521 needs to be greater than the diameter of a single roll 200 and less than the diameters of two rolls 200. And for the first insert plate 2524 and the second insert plate 2525 which are arranged up and down on the conveying channel 2523 near the blanking port 2521, the second insert plate 2525 is used for controlling the switch of the blanking port 2521, and the first insert plate 2524 and the second insert plate 2525 form a space for accommodating a single paper roll 200 in the area between the conveying channels 2523, so that the first insert plate 2524 and the second insert plate 2525 are driven by the insert plate driving parts 2526 correspondingly arranged to enable the first insert plate 2524 and the second insert plate 2525 to alternately slide, and single paper roll 200 output is realized.

Still further, in order to guide the smooth entry of the paper rolls 200 in the storage bin 2522 into the transport path 2523, an inclined guide portion 2527 is formed at the bottom of the storage bin 2522, and the inclined guide portion 2527 is inclined upwardly along the connection port.

Specifically, the rolls 200 at the bottom of the storage 2522 can be aligned and slid into the transport path 2523 via the inclined guide 2527 to ensure smooth output of the rolls 200.

Further, since the paper rolls 200 are long in the length direction, the paper rolls 200 stored in the storage bins 2522 are easy to cross at the connection ports, so that the paper rolls 200 cannot enter the conveying passages 2523, and for this purpose, the feeding assembly 25 further comprises a poking module 253, and the poking module 253 comprises a poking rod 2531, two connecting rods 2532 and a poking driving part 2533, and the poking rod 2531 is connected between the two connecting rods 2532; the connecting rod 2532 and the shift lever 2531 are located in the storage bin 2522, an upper end portion of the connecting rod 2532 is hinged to the inclined guide portion 2527, the shift lever 2531 is close to the connection port and extends along the length direction of the connection port, and the shift driving component 2533 is configured to drive the connecting rod 2532 to rotate.

Specifically, when the paper roll 200 of the storage bin 2522 near the connection port is blocked due to cross interference, the paper roll 200 at the bottom of the storage bin 2522 can be stirred by the stirring module 253, and the stirring driving component 2533 drives the stirring rod 2531 to move up and down at the connection port through the connecting rod 2532 so as to stir and comb the paper roll 200 at the connection port. The shift lever 2531 extends along the length direction of the connection port, so that the crossed paper rolls 200 can be combed smoothly under the shifting action of the shift lever 2531, so that the problem of cross blockage of the paper rolls 200 is solved, and smooth output of the paper rolls 200 is ensured.

Preferably, a baffle 2528 is further disposed at the connection port, the baffle 2528 is disposed in the storage bin 2522 and on the inclined guide portion 2527, and the baffle 2528 is disposed between the lever 2531 and the connection port.

Specifically, during the process of pulling the paper roll 200 by the pulling rod 2531, the baffle 2528 matched with one side of the pulling rod 2531 can better correct the skewed paper roll 200 to a correct posture.

Wherein, the lower end of the baffle 2528 is disposed on the inclined guide portion 2527, and the upper end of the baffle 2528 is formed with a positioning surface which is vertically disposed and parallel to the inner wall of the conveying passage 2523. Specifically, in the process of shifting the shift lever 2531, after the paper roll 200 between the shift lever 2531 and the baffle 2528 is corrected, the paper roll 200 can be further guided to slide into the connection port below in a correct posture through the baffle 2528 after bypassing the baffle 2528 along the positioning surface at the top.

Still further, in order to meet the winding requirements of different size films, the storage bin 2522 also needs to meet the feeding requirements of different length rolls 200, so as to improve versatility. The storage bin 2522 is further provided with an adjusting plate 254, the adjusting plate 254 is vertically arranged and can be horizontally arranged in the storage bin 2522 in a sliding mode, the outline of the adjusting plate 254 is matched with the outline of the section of the storage bin 2522 perpendicular to the length direction, the bottom of the adjusting plate 254 is further provided with an extending plate 255, and the extending plate 255 extends into the conveying channel 2523.

For example: the side wall of the storage bin 2522 is provided with a strip-shaped hole which is transversely arranged, the adjusting plate 254 is provided with a threaded hole, and a bolt passes through the strip-shaped hole and is in threaded connection with the threaded hole.

Based on the above-mentioned technical solution, optionally, in order to meet the requirements of the inflatable shaft 4 for automatically unloading the film roll 100 and automatically loading the paper roll 200 by the automatic loading and unloading device 2, an improved structural design is also performed on the inflatable shaft 4, and the following description is made with reference to fig. 15-17.

Specifically, an air chamber is formed in the inflation and deflation shaft 41 to inflate the air chamber through the inflation and deflation holes to cause the expansion members to expand outwardly. Meanwhile, the air in the air cavity can be leaked out through the air charging and discharging holes, so that the retraction of the expansion part is realized. For a specific manner of expanding and contracting the expansion member on the inflation and deflation shaft 41, reference may be made to the structural configuration of the conventional inflation shaft 4, without limitation.

By disposing an inflation/deflation hole at one end of the inflation/deflation shaft 41, the inflation requirement can be satisfied, and the deflation requirement can be satisfied. And further can be matched with the automatic loading and unloading equipment 2 to be inflated and deflated through the inflation and deflation part 242 of the inflation and deflation assembly 24 in the use process.

For the air tap 42, a pressing opening mode is adopted, such as a pressing air tap in the conventional technology. Thus, during inflation and deflation, the inflation and deflation member 242 abuts against the air tap 42 to effect opening of the air tap 42 and communication with the first vent 2421, and then inflation and deflation operations are performed according to inflation and deflation requirements.

Meanwhile, since the air expansion shaft 4 is to automatically sleeve a new paper roll 200, in order to ensure the accuracy of sleeving the paper roll 200, a positioning sleeve 43 is provided at one end of the air inflation and deflation shaft 41, and the positioning sleeve 43 can position the paper roll 200 sleeved on the air inflation and deflation shaft 41.

During the process of bringing a new roll 200 of paper over the inflation and deflation shaft 41 by means of the support bracket 23, the roll 200 will rest against the positioning sleeve 43 to ensure that the roll 200 is assembled in place. The positioning sleeve 43 can meet the requirement of the assembly precision of the paper roll 200 in the automatic sleeving process of the paper roll 200, so as to ensure that the paper roll 200 can be automatically assembled in place.

Further, an end face of one end of the inflation/deflation shaft 41 is provided with a plugging groove 44, and the plugging groove 44 is provided with an inflation/deflation hole.

Specifically, by arranging the insertion groove 44 at the end of the air expansion shaft 4, the insertion groove 44 can meet the installation requirement of the air tap 42, and is arranged in the insertion groove 44 to avoid being knocked to improve the use reliability, and on the other hand, the insertion groove 44 can play a role in guiding the air charging and discharging part 242 to be accurately inserted into the interior to open the air tap 42.

Wherein, in order to improve the sealing reliability of the connection, the free end of the air charging and discharging part 242 has a conical structure; when the inflatable shaft 4 is inflated and deflated, the free end of the inflation and deflation member 242 is sealingly inserted into the insertion groove 44.

Still further, in the automatic loading and unloading process of the inflatable shaft 4, since the inflatable shaft 4 needs to be clamped by the inflation and deflation assembly 24 of the automatic loading and unloading device 2 and one end is arranged in a suspended manner, in order to improve the clamping reliability of the inflatable shaft 4, the outer surface of the inflation and deflation shaft 41 is further provided with an annular positioning groove 45, and the annular positioning groove 45 is arranged on the outer side of the positioning sleeve 43.

Specifically, after the inflatable shaft 4 is placed on the support bracket 23 of the automatic loading and unloading device 2, the unloading clamping plate 246 of the inflating and deflating assembly 24 is clamped in the annular positioning groove 45, and meanwhile, the free end of the inflating and deflating shaft 41 is clamped and fixed by the clamping component. Thus, after the support bracket 23 of the automatic loading and unloading device 2 drives the film frame to separate from the inflatable shaft 4, one end of the inflatable shaft 4 is effectively supported by the clamping component and the unloading clamping plate 246, so as to meet the requirement of suspension arrangement of the other end of the inflatable shaft 4 on the stability of the posture.
