Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and in particular to an automatic film winding and packaging system and its control method. Background Technology

[0002] Plastic products, with their lightweight, good electrical insulation, wide range of mechanical strength, good thermal insulation, excellent processing performance, and superior chemical corrosion resistance, have been used in automobiles, home appliances, agriculture, medicine, various packaging, defense, aerospace, and other fields since the early 20th century. Among these applications, with the continuous development of solar power generation technology, solar panels are widely used in production. Solar cell encapsulation film (EVA film), used as an interlayer in laminated glass, is a crucial material in the processing of solar panels. Solar EVA film is typically produced by extrusion and then cast into a film. After extrusion and casting, the film needs to be wound up. Chinese Patent Publication No. CN113443481A discloses an automatic film winding machine that automatically winds the film using an air-expanding shaft. However, the wound film rolls are generally manually removed from the winding machine using hoisting equipment and then transported to packaging equipment for lamination and packaging. Simultaneously, workers need to simultaneously load paper rolls onto the air-expanding shaft during the unloading process, resulting in high labor intensity and low automation. Therefore, how to design a winding device with improved automation is the technical problem that this invention aims to solve. Summary of the Invention

[0003] This invention provides an automatic film winding and packaging system and its control method, which enables the automatic film winding and packaging system to automatically load and unload air expansion shafts and complete the automatic packaging of film rolls, thereby improving the degree of automation and reducing the labor intensity of workers.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: This invention provides an automatic film winding and packaging system, comprising: A winding machine includes a frame, a friction roller, a roll drive module, and a lifting module. The friction roller is rotatably mounted on the frame. The roll drive module has a power output component, which is rotatably mounted on the frame and located on one side of the friction roller. The power output component is configured to drive an air shaft to rotate on one side of the friction roller to wind a film roll on the air shaft. The lifting module is provided with a lifting clamp that is movable relative to the frame. An automatic loading and unloading device includes a loading and unloading frame, a sliding frame, a support frame, an inflation / deflation assembly, and a supply assembly. The inflation / deflation assembly is located at one end of the loading and unloading frame and configured to clamp an air expansion shaft and inflate or deflate it. The sliding frame is slidably mounted on the loading and unloading frame, and the support frame is mounted on the sliding frame. The supply assembly includes a support frame and a material box. The bottom of the material box is provided with an openable discharge port. The support frame is mounted on the loading and unloading frame and located away from the inflation / deflation assembly. The material box is mounted on the support frame. A packaging and transfer device includes a packaging frame, a support frame, and a film clamping assembly. The packaging frame has a bearing seat at its top, configured to support a packaging roll wound with packaging film. The support frame is rotatably mounted on the packaging frame and has at least one rotatable support roller extending along the axis of rotation of the support frame. The film clamping assembly includes a film clamping component and a film clamping lifting seat. The film clamping lifting seat is slidably mounted on the packaging frame and located above the support frame. The film clamping component is mounted on the film clamping lifting seat and configured to clamp the packaging film output from the packaging roll. The automatic loading and unloading equipment is arranged on one side of the winding machine, the lifting clamp is configured to place the air shaft with the film wound on the support frame, the lifting clamp is also configured to place the air shaft on the support frame on the machine frame, the packaging and transfer equipment is arranged on one side of the automatic loading and unloading equipment, and the carrier frame is configured to receive the film roll output from the support frame.

[0005] The present invention also provides a control method for the above-mentioned automatic film winding and packaging system, comprising: The winding machine drives the air shaft through the roll drive module to rotate the paper roll to complete the winding of the film onto the paper roll to form a film roll. After the air shaft and film roll that have been wound are placed on the support frame of the automatic loading and unloading equipment. The automatic loading and unloading equipment's inflation and deflation components clamp the end of the air shaft and connect the inflation and deflation components to the inflation and deflation holes of the air shaft to deflate it. The sliding frame slides away from the inflation and deflation components so that the support frame drives the film roll away from the air shaft. The support frame flips so that the film roll rolls onto the carrier frame of the packaging and transfer equipment. Then, the material box's discharge port opens so that the paper roll falls onto the support frame. The sliding frame moves back to its original position and puts the paper roll onto the air shaft. The inflation and deflation components then inflate the air shaft again. Finally, the air shaft with the paper roll is lifted by the lifting clamp and put into the recycling machine for later use. The film clamping component of the packing and transfer equipment clamps the packaging film and moves it downward so that the packaging film adheres to the film roll. The support roller rotates to drive the film roll to rotate so that the packaging film is wrapped around the film roll to complete the packing.

[0006] The technical solution of this invention has the following advantages over the prior art: By configuring a lifting module on the winding machine, the lifting clamps of the lifting module can meet the requirements of automatic loading and unloading of the air shaft, thereby realizing the unloading and transportation of the wound air shaft to the automatic loading and unloading equipment, and also the transportation of air shafts with empty paper rolls to the winding machine for later use, so as to realize the automatic loading and unloading of the air shaft; while the wound air shaft is held by the inflation and deflation component in the automatic loading and unloading equipment and deflated, so that the film roll can move with the sliding frame to detach from the air shaft and further rely on the support. The automatic loading and unloading equipment transfers the film rolls to the support frame of the packaging and transfer equipment for automatic packaging. The supply component of the automatic loading and unloading equipment can supply new paper rolls to the support frame. After the sliding frame slides back to its original position, the paper rolls are then placed on the air shaft. The inflation and deflation component re-inflates the air shaft, and then it can be hoisted onto the frame of the winding machine by the hoisting clamp for later use. The automatic loading and unloading equipment can automatically complete the inflation and deflation of the air shaft and the replacement of paper rolls. Thus, the automatic film winding and packaging system can automatically load and unload the air shaft and complete the automatic packaging of the film rolls, thereby improving the degree of automation and reducing the labor intensity of workers.

Implementation

[0008] Example 1, as Figures 1-2 As shown, this embodiment provides an automatic film winding and packaging system, including a winding machine 1. The winding machine 1 can automatically wind up films that need to be wound. During winding, the winding machine 1 needs to cooperate with an air shaft 4, that is, a paper roll 200 is sleeved on the air shaft 4, and the film is wound on the paper roll 200. A conventional winding machine 1 usually has a friction roller 12 and a roll drive module 13. The friction roller 12 winds the film onto the paper roll 200 on the air shaft 4, and the roll drive device can drive the air shaft 4 to rotate to achieve the winding of the paper roll 200. The specific structure of the winding machine 1 to achieve film winding is not limited here, and the structure of the winding machine 1 in conventional technology can be used.

[0009] To enable automatic loading and unloading of the air shaft 4, and the automatic detachment of the film roll 100 from the air shaft 4 for replacement with a new paper roll 200, the winding machine 1 requires structural modifications, including the addition of a lifting module 14. The lifting module 14 utilizes lifting fixtures to load or unload the air shaft 4. Furthermore, the automatic film winding and packaging system further includes an automatic loading and unloading device 2, which automatically detaches the film roll 100 from the air shaft 4 and replaces it with a new paper roll 200. The specific structural configuration of the automatic film winding and packaging system is described below with reference to the accompanying drawings.

[0010] like Figures 3-5As shown, the winding machine 1 includes a frame 11, a friction roller 12, a roll drive module 13, and a hoisting module 14. The friction roller 12 is rotatably mounted on the frame 11. The roll drive module 13 has a power output component (such as a gear). The power output component is rotatably mounted on the frame 11 and located on one side of the friction roller 12. The power output component is configured to drive an air shaft 4 to rotate on one side of the friction roller 12 to wind a paper roll 200 on the air shaft 4 to form a film roll 100. The hoisting module 14 is provided with a hoisting clamp that is movable relative to the frame 11.

[0011] The automatic loading and unloading equipment 2 includes a loading and unloading frame 21, a sliding frame 22, a support frame 23, an inflation / deflation assembly 24, and a supply assembly 25. The inflation / deflation assembly 24 is disposed at one end of the loading and unloading frame 21 and configured to clamp the air expansion shaft 4 and inflate or deflate the air expansion shaft 4. The sliding frame 22 is slidably disposed on the loading and unloading frame 21. The support frame 23 is disposed on the sliding frame 22. The supply assembly 25 includes a support frame 251 and a material box 252. The bottom of the material box 252 is provided with an openable discharge port 2521. The support frame 251 is disposed on the loading and unloading frame 21 and away from the inflation / deflation assembly 24. The material box 252 is disposed on the support frame 251.

[0012] Specifically, the rewinding machine 1 is additionally equipped with a hoisting module 14 to realize the automatic loading and unloading of the air shaft 4. The hoisting fixture configured in the hoisting module 14 can hoist the air shaft 4 so that the paper roll 200 on the air shaft 4 can be hoisted from the frame 11 to the automatic loading and unloading equipment 2 after it is wound into a film roll 100. It can also hoist the air shaft 4 with a new paper roll 200 assembled in the automatic loading and unloading equipment 2 into the rewinding machine 1.

[0013] In order to meet the requirements of automatic loading and unloading of paper rolls 200 on the air shaft 4, the packaging and transfer equipment 3 must be able to automatically unload the paper rolls 200 with film wound on the air shaft 4, and then load the new paper rolls 200 onto the air shaft 4.

[0014] Therefore, for the air expansion shaft 4 that is unwound from the winding machine 1 to form the film roll 100, the film roll 100 is placed on the support frame 23 with the air expansion shaft 4 connected to it. Then, the inflation / deflation assembly 24 can hold the air expansion shaft 4 and deflate it.

[0015] After the air shaft 4 is deflated, the sliding frame 22 slides away from the inflation / deflation assembly 24, so that the paper roll 200 connecting film is disengaged from the air shaft 4, while the air shaft 4 is held by the inflation / deflation assembly 24 to keep one end suspended.

[0016] When the film roll 100 on the support frame 23 on the sliding frame 22 leaves the air shaft 4, the film roll 100 can be unloaded from the automatic loading and unloading equipment 2 to free up the support frame 23. At this time, the supply component 25 can supply a new paper roll 200 from the material box 252 to the support frame 23.

[0017] After a new paper roll 200 is placed on the support frame 23, the sliding frame 22 moves back toward the inflation / deflation assembly 24 so that the paper roll 200 on the support frame 23 is once again placed on the air shaft 4. Then, the inflation / deflation assembly 24 re-inflates the air shaft 4 to fix the paper roll 200 on the air shaft 4. At this time, the air shaft 4 on the support frame 23 can be hoisted onto the frame 11 of the winding machine 1 by the hoisting module 14 for later use.

[0018] In one embodiment of this application, the following structural design and improvement were made to the specific structural form of the hoisting module 14 in the winding machine 1, which is described below in conjunction with the appendix. Figures 3-5 Please provide an explanation.

[0019] like Figures 3-5 As shown, the hoisting module 14 includes a loading assembly 141, and the hoisting fixture includes a loading fixture 142; The loading assembly 141 includes a lifting bracket 1411 and a synchronous movement assembly 1412. The synchronous movement assembly 1412 includes a synchronous shaft 14121, a plurality of synchronous pulleys 14122, two synchronous belts 14123, and a synchronous drive component 14124. The synchronous pulleys 14122 are respectively arranged at the four corners of the lifting bracket 1411, wherein a pair of oppositely arranged synchronous pulleys 14122 are connected by the synchronous shaft 14121. The synchronous belts 14123 are wound around the two synchronous pulleys 14122 on the corresponding sides. The synchronous drive component 14124 is configured to drive the synchronous shaft 14121 to rotate. The loading clamp 142 is disposed on the synchronous belts 14123, and the lifting bracket 1411 is fixed to the top of the frame 11.

[0020] Specifically, for the air shaft 4 equipped with a new paper roll 200, the air shaft 4 can be held by the loading clamp 142 and moved and hoisted onto the frame 11 for standby use in conjunction with the loading assembly 141. The hoisting bracket 1411 is mounted on the top of the frame 11, and the loading clamp 142 can be driven to move back and forth by the synchronous belt 14123 to realize the hoisting of the air shaft 4.

[0021] Furthermore, for the loading clamp 142, in order to facilitate the hoisting of the air shaft 4, the loading clamp 142 includes a hanging beam 1421, a guide rod 1422, a lifting cylinder 1423, a drive cylinder 1424, a connecting seat 1425, and a hook 1426. The hanging beam 1421 is slidably mounted on the hoisting bracket 1411 and connected to the synchronous belt 14123. The guide rod 1422 is erected on the hanging beam 1421. The connecting seat 1425 is slidably mounted on the guide rod 1422. The lifting cylinder 1423 is located between the hanging beam 1421 and the connecting seat 1425. The hook 1426 is rotatably mounted on the connecting seat 1425. The drive cylinder 1424 is hinged between the hook 1426 and the connecting seat 1425.

[0022] Specifically, the loading clamp 142 can move with the loading assembly 141 to meet the requirements of lifting and unloading the air shaft 4. When lifting the air shaft 4, the loading clamp 142 moves with the timing belt 14123, extending the loading clamp 142 to the outside of the frame 11. Then, the lifting cylinder 1423 lowers the connecting seat 1425, positioning the hook 1426 below both ends of the air shaft 4. The drive cylinder 1424 actuates to rotate the hook 1426, thereby hooking the air shaft 4. The lifting cylinder 1423 raises the connecting seat 1425, and then the timing belt 14123 moves the loading clamp 142 in the opposite direction, moving the air shaft 4 to a position above the frame 11 for storage. The drive cylinder 1424 actuates to rotate the hook 1426 in the opposite direction to release the air shaft 4, which is then placed on the frame 11 for later use.

[0023] Furthermore, in order to automatically unload the completed air-expansion shaft 4 connected to the film roll 100 from the frame 11, the hoisting module 14 also includes an unloading component 143, and the hoisting fixture includes an unloading fixture 144.

[0024] The unloading assembly 143 includes an unloading drive component 1431 and a connecting shaft 1432. The unloading fixture 144 includes two lifting arms 1441, the lower ends of which are respectively disposed at the corresponding ends of the connecting shaft 1432. The upper ends of the lifting arms 1441 are provided with lifting slots 1442. The connecting shaft 1432 is rotatably disposed on the frame 11. The unloading drive component 1431 is configured to drive the connecting shaft 1432 to rotate.

[0025] Specifically, the two side-by-side lifting arms 1441 of the unloading fixture 144 are fixedly mounted on the same connecting shaft 1432, and the connecting shaft 1432 can be driven to rotate on the frame 11 by the unloading drive component 1431, so that the lifting arms 1441 can swing up and down with the connecting shaft 1432.

[0026] In actual use, after the roll drive module 13 drives the air shaft 4 to rotate and completes the winding of the paper roll 200 onto the film, the air shaft 4, connected to the film roll 100, disengages from the roll drive module 13 and is supported by the lifting arm 1441. The two ends of the air shaft 4 are then engaged in the corresponding lifting slots 1442. At this time, the air shaft 4 and the film roll 100 are supported on the lifting arm 1441, and the connecting shaft 1432 is driven to rotate by the unloading drive component 1431, so that the lifting arm 1441 drives the air shaft 4 and the film roll 100 to move downwards to achieve the unwinding operation.

[0027] Furthermore, in order to enable the air shaft 4 to automatically roll onto the lifting arm 1441 after it has finished winding and disengaged from the reel drive module 13, the frame 11 is provided with transversely arranged slide rails 15 on both sides. The reel drive module 13 is slidably mounted on the slide rails 15. The outer end surface of the slide rail 15 forms an inclined rail surface 151, which extends downward toward the lifting arm 1441.

[0028] Specifically, in conventional technology, the reel drive module 13 uses a motor to drive a drive gear to rotate, which in turn engages with a driven gear on the air shaft 4 to achieve the rotation of the air shaft 4. After the winding operation is completed on the air shaft 4, the drive gear of the reel drive module 13 disengages from the driven gear on the air shaft 4, and the air shaft 4 falls onto the inclined rail surface 151 after detaching from the reel drive module 13. Since the inclined rail surface 151 is an inclined surface and tilts downwards towards the lifting arm 1441, the air shaft 4 can automatically slide along the inclined rail surface 151 to the lifting arm 1441 by its own weight, thereby realizing the automatic unwinding operation through the lifting arm 1441.

[0029] In another embodiment of this application, the automatic loading and unloading equipment 2 needs to meet the requirements of automatic paper roll unloading 200 and automatic paper roll loading 200 of the air shaft 4. Regarding the specific structural form of the automatic loading and unloading equipment 2, in conjunction with the appendix... Figures 6-11 Please provide an explanation.

[0030] The automatic loading and unloading equipment 2 includes a loading and unloading frame 21, a sliding frame 22, a support frame 23, an inflation / deflation assembly 24, and a supply assembly 25. The inflation / deflation assembly 24 is located at one end of the loading and unloading frame 21. The inflation / deflation assembly 24 can hold the air expansion shaft 4 unloaded from the hoisting module 14, and can also perform inflation and deflation operations on the air expansion shaft 4 as needed.

[0031] The sliding frame 22 can drive the support to slide back and forth between the inflation / deflation assembly 24 and the supply assembly 25. The support frame 23 is disposed on the sliding frame 22 and is used to support the air expansion shaft 4 and the film roll 100, and also to carry new paper rolls 200. The supply assembly 25 includes a support frame 251 and a material box 252. The material box 252 is used to hold new paper rolls 200, and a switchable discharge port 2521 is provided at the bottom of the material box 252 to feed new paper rolls 200 through the discharge port 2521. The support frame 251 is disposed on the loading / unloading frame 21 and away from the inflation / deflation assembly 24. The material box 252 is disposed on the support frame 251.

[0032] Specifically, when the air shaft 4 is wound up, the sliding frame 22 moves to the inflation / deflation assembly 24, and the air shaft 4 and the film roll 100 are placed on the support frame 23. At the same time, the inflation / deflation assembly 24 will clamp the corresponding ends of the air shaft 4 to deflate the air shaft 4.

[0033] After the air shaft 4 is deflated, the paper roll 200 in the film roll 100 can easily detach from the air shaft 4. At this time, the sliding frame 22 moves away from the inflation / deflation assembly 24, the air shaft 4 is still held by the inflation / deflation assembly 24, and the film roll 100 moves with the support frame 23 and gradually detaches from the air shaft 4 along the axial direction of the air shaft 4.

[0034] After the film roll 100 is detached from the air shaft 4, it can be removed from the automatic loading and unloading device 2. The feed hopper 252 in the supply assembly 25 can then open its discharge port 2521, allowing a paper roll 200 to fall onto the feed hopper 23. The feed hopper 23 moves towards the inflation / deflation assembly 24 via the sliding frame 22, so that the paper roll 200 on the feed hopper 23 is then placed back onto the air shaft 4. After the new paper roll 200 is placed onto the air shaft 4, the inflation / deflation assembly 24 inflates the air shaft 4, ensuring the new paper roll 200 is securely tightened on the air shaft 4 for rewinding.

[0035] By configuring the inflation / deflation assembly 24 and the supply assembly 25, on the one hand, the inflation / deflation assembly 24 can also inflate and deflate the air 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 / deflation assembly 24 can clamp the air shaft 4 to ensure that the air shaft 4 is effectively supported after the film roll 100 is detached from the air shaft 4 and to meet the requirements of loading the new paper roll 200. At the same time, the sliding frame 22 drives the support frame 23 to move. The support frame 23 can unload the film roll 100 and move the new paper roll 200 to be assembled onto the air shaft 4, thereby realizing automatic loading and unloading of the air shaft 4 without manual intervention, improving the degree of automation and reducing the labor intensity of workers, so as to improve production efficiency.

[0036] Furthermore, the inflation / deflation assembly 24 must meet the requirements of inflation / deflation of the air shaft 4 and clamping support. Therefore, the inflation / deflation assembly 24 includes an inflation / deflation base 241, an inflation / deflation component 242, two clamping components 243, a clamping drive component 244, and a reciprocating drive component 245. The two clamping components 243 are arranged opposite to each other. The clamping drive component 244 is configured to drive the two clamping components 243 to slide relative to each other on the inflation / deflation base 241. The inflation / deflation component 242 is located between the two clamping components 243. The reciprocating drive component 245 is configured to drive the inflation / deflation component 242 to slide on the inflation / deflation base 241. The inflation / deflation component 242 is provided with a first vent 2421 and a second vent 2422 that are interconnected. The first vent 2421 is arranged at the free end of the inflation / deflation component 242, and the second vent 2422 is configured to connect to an inflation machine. The inflation / deflation base 241 is provided on the loading / unloading frame 21.

[0037] Specifically, the inflation / deflation base 241 is equipped with two opposing clamping components 243. The two clamping components cooperate with each other to clamp and support the air expansion shaft 4. The two clamping components are driven to move closer or further apart by the clamping drive component 244 (such as a cylinder or electric push rod). Both clamping components can move, or one clamping component can be fixed while the other moves.

[0038] After the air shaft 4 and the membrane roll 100 are placed on the support frame 23, the end of the air shaft 4 will be located between the two clamping components. The clamping drive component 244 drives the two clamping components to clamp the air shaft 4 between them, so that the air shaft 4 can be clamped and supported by the clamping component 243.

[0039] After the air shaft 4 is clamped, the inflation / deflation component 242 moves toward the end of the air shaft 4 under the driving action of the reciprocating drive component 245 (such as a cylinder or electric actuator) to mate with the inflation / deflation port of the air shaft 4. In this way, the first vent 2421 communicates with the internal air cavity of the air shaft 4, while the inflator connected to the second vent 2422 allows the second vent 2422 to communicate with the outside when not inflating, thereby achieving the deflation process of the air shaft 4.

[0040] When a new paper roll 200 is replaced on the air shaft 4, the air inflator inflates the second vent 2422 to inject gas into the air chamber of the air shaft 4. After the air shaft 4 expands, the paper roll 200 is fixed on the air shaft 4.

[0041] In order to improve the reliability of the support for the air expansion shaft 4, the inflation / deflation base 241 is also provided with an unloading plate 246, which has a support groove for positioning the air expansion shaft 4.

[0042] Specifically, after the air shaft 4 and the membrane roll 100 are placed on the support frame 23, the end of the air shaft 4 will be located between the two clamping components, and at the same time, the air shaft 4 will also be locked in the support groove of the unloading plate 246. After the end of the air shaft 4 is clamped by the two clamping components, the unloading plate 246 will further support the air shaft 4 to form two-point support on the air shaft 4, thereby improving the support reliability of the air shaft 4.

[0043] Correspondingly, an annular positioning groove 45 can be provided on the air shaft 4 to cooperate with the unloading plate 246, so that the unloading plate 246 can be locked in the annular positioning groove 45 to limit the air shaft 4 in the axial direction.

[0044] Furthermore, in order to improve the clamping reliability of the air shaft 4, the clamping component is provided with a clamping groove (unmarked), and a clamping space is formed between the two clamping grooves; after the air shaft 4 is clamped by the two clamping components, the air shaft 4 is located in the two clamping grooves.

[0045] Specifically, when the air shaft 4 is clamped by the clamping component, in order to effectively position the air shaft 4, a clamping groove can be provided on the clamping component. The contour of the clamping groove matches the outer contour of the air shaft 4. The air shaft 4 is clamped in the clamping groove to ensure that the air shaft 4 can be accurately positioned and effectively clamped and supported.

[0046] Furthermore, a support groove 231 is formed on the support frame 23, and the cross-section of the support groove 231 is a V-shaped structure.

[0047] Specifically, the longitudinal section of the support frame 23 is V-shaped, so that after the film roll 100 is placed on the support frame 23, the position of the film roll 100 can be positioned by itself; and when the paper roll 200 output from the material box 252 falls onto the support frame 23, the support frame 23 can be positioned by the V-shaped support groove 231 formed therein, so as to ensure that the paper roll 200 can be accurately fitted onto the air expansion shaft 4.

[0048] To ensure the paper roll 200 is properly seated when it is fitted onto the air shaft 4, the supporting groove 231 has two relatively inclined supporting surfaces. Each supporting surface has a through hole. The supporting bracket 23 is equipped with a slidable limiting pin 232, which is inserted into the corresponding through hole. The limiting pins 232, located opposite each other on the two supporting surfaces, are inclined to each other and, after extending out of the through hole, form a clamping space between themselves and the supporting surfaces for holding the paper roll 200.

[0049] Specifically, after the new paper roll 200 is placed onto the support frame 23, the paper roll 200 will be positioned between two support surfaces. Then, a driving component such as a cylinder will extend the limiting pins 232, so that the paper roll 200 is clamped onto the support surface by the two cross-arranged limiting pins 232. During the loading process, as the paper roll 200 is moved towards the air expansion shaft 4 by the sliding frame 22, the paper roll 200 is pressed against the support surface by the limiting pins 232 and will not be displaced due to contact with the air expansion shaft 4. In this way, it can be ensured that the paper roll 200 can be reliably mounted on the air expansion shaft 4 and meet the requirements of the paper roll 200 being assembled in place.

[0050] In actual use, there are multiple ways to unload the paper roll 200 from the support frame 23. For example, the support frame 23 can automatically unload the film roll 100 by flipping itself. Specifically, the support frame 23 is rotatably mounted on the sliding frame 22, and a flipping drive component 26 is also provided between the support frame 23 and the loading and unloading frame 21.

[0051] Specifically, in actual use, after the membrane roll 100 on the support frame 23 detaches from the air shaft 4, the sliding frame 22 has already driven the support frame 23 away from the air shaft 4. At this time, the flipping drive component 26 is activated to flip the support frame 23. After flipping, one of the supporting surfaces of the support frame 23 will extend downwards at an angle, so that the membrane roll 100 rolls down from the support frame 23 along the downwardly extending supporting surface by gravity, thereby realizing automatic unloading of the membrane roll 100.

[0052] The unloading method using the aforementioned support frame 23 can meet the requirements of subsequent automatic wrapping. For cases requiring manual intervention in unloading, the automatic loading and unloading equipment 2 also includes a transfer assembly 27. The transfer assembly 27 includes a transfer seat 271, a transfer support shaft 272, and a rotary drive component 273. The transfer support shaft 272 is arranged laterally and rotatably mounted on the transfer seat 271. The rotary drive component 273 is configured to drive the transfer support shaft 272 to reciprocate. The inflation / 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 mounted on the loading and unloading frame 21.

[0053] Specifically, regarding the film roll 100 on the support frame 23, during use, there may be situations where the film roll 100 has quality issues that prevent it from being wrapped and packaged, or where the film roll 100 requires manual packaging. In these cases, during the separation of the film roll 100 from the air expansion shaft 4 on the support frame 23, the transfer support shaft 272 in the transfer assembly 27, which is located at different ends of the loading / unloading frame 21 from the inflation / deflation assembly 24, is essentially coaxial with the air expansion shaft 4. After the air expansion shaft 4 deflates, the sliding frame 22 moves the support frame 23, causing the film roll 100 to detach from the air expansion shaft 4. Simultaneously, the transfer support shaft 272 inserts from the other side of the film roll 100 into the paper roll 200 of the film roll 100, thus supporting the film roll 100.

[0054] After the film roll 100 is supported by the transfer support shaft 272, the transfer support shaft 272 is driven to rotate by the rotation drive component 273, so that the film roll 100 rotates away from the support frame 23, thereby meeting the requirement of manually unloading the film roll 100 from the transfer support shaft 272. At the same time, the support frame 23 can be emptied in time, and a new paper roll 200 can be put into the material box 252 above for use.

[0055] Furthermore, to facilitate the installation of the transfer support shaft 272, a transfer bracket 274 is provided on the transfer seat 271, and a vertically arranged shaft 275 is provided between the transfer bracket 274 and the transfer seat 271. The transfer support shaft 272 is mounted on the shaft 275, and the rotation drive component 273 is mounted on the transfer bracket 274 and connected to the shaft 275.

[0056] Specifically, the transfer bracket 274 provided on the transfer seat 271 can meet the installation requirements of the transfer support shaft 272 and the rotary drive component 273. The vertical shaft 275 provided on the transfer bracket 274 can meet the requirements of the horizontal rotation of the transfer support shaft 272. The rotary drive component 273 can be a rotary cylinder or motor or other components to drive the vertical shaft 275 to rotate, thereby driving the transfer support shaft 272 to rotate.

[0057] Furthermore, the loading and unloading frame 21 includes a base frame 211 and two upright frames 212. The base frame 211 is arranged horizontally, and the upright frames 212 are arranged vertically and fixed to the corresponding ends of the base frame 211. The sliding frame 22 is located between the two upright frames 212 and is slidably mounted on the base frame 211. A lifting drive component 213 is provided on the upright frame 212. The inflation / deflation base 241 is slidably mounted on the upright frame 212 and connected to the corresponding lifting drive component 213. The transfer seat 271 is slidably mounted on the upright frame 212 and connected to the corresponding lifting drive component 213.

[0058] Specifically, both the inflation / deflation assembly 24 and the transfer assembly 27 can move up and down on their respective supports 212. Since the height of the support frame 23 remains constant, when the film roll 100 is placed on the support frame 23, the large diameter of the film roll 100 results in a relatively high height for the air shaft 4 and the paper roll 200. In this case, the inflation / deflation assembly 24 needs to be raised accordingly so that the end of the air shaft 4 can be positioned between the two clamping components. Simultaneously, when the film roll 100 needs to be transferred to the transfer support shaft 272, the transfer assembly 27 is raised accordingly so that the height of the transfer support shaft 272 matches the height of the paper roll 200 within the film roll 100.

[0059] Simultaneously, when a new paper roll 200 is placed on the support 23 to fit onto the air expansion shaft 4 held by the inflation / deflation assembly 24, since the height of the paper roll 200 on the support 23 is relatively low, the overall height of the inflation / deflation assembly 24 needs to be lowered so that the height of the air expansion shaft 4 matches the height of the paper roll 200 on the support 23. This satisfies the requirements for automatic unloading of the film roll 100 from the air expansion shaft 4 and automatic assembly of the new paper roll 200 onto the air expansion shaft 4.

[0060] Furthermore, for the material bin 252, which stores several paper rolls 200, in order to meet the requirement of outputting one paper roll 200 at a time through the feed port 2521, the material bin 252 is structurally improved as follows.

[0061] The material bin 252 includes a storage bin 2522 and a conveying channel 2523. The bottom of the storage bin 2522 is provided with a connection port (unmarked). The conveying channel 2523 is arranged vertically and is located on the connection port. The bottom of the conveying channel 2523 forms the discharge port 2521. The side wall of the conveying channel 2523 is provided with a first insertion hole and a second insertion hole arranged vertically. The side wall of the conveying channel 2523 is also provided with a slidable first insertion plate 2524, a second insertion plate 2525 and an insertion plate driving component 2526. The first insertion plate 2524 is inserted into the first insertion hole and the second insertion plate 2525 is inserted into the second insertion hole. The second insert plate 2525 is located below the first insert plate 2524, and the second insert plate 2525 is configured to open and close the feed port 2521; and the first insert plate 2524 and the second insert plate 2525 form a temporary storage space in the conveying channel 2523 to accommodate a single paper roll 200.

[0062] Specifically, the storage bin 2522 has a large volume and a wide width, capable of holding several paper rolls 200. However, the width of the conveying channel 2523 at the bottom of the storage bin 2522 is relatively small compared to the width of the storage bin 2522. In particular, the width of the conveying channel 2523 at the discharge port 2521 needs to be greater than the diameter of a single paper roll 200 but less than the diameter of two paper rolls 200. The conveying channel 2523 has a first insert plate 2524 and a second insert plate 2525 arranged vertically near the discharge port 2521. The second insert plate 2525 controls the opening and closing of the discharge port 2521. The area between the first insert plate 2524 and the second insert plate 2525 in the conveying channel 2523 forms a space to accommodate a single paper roll 200. The insert plate driving component 2526 corresponding to the first insert plate 2524 and the second insert plate 2525 drives the first insert plate 2524 and the second insert plate 2525 to slide alternately, so as to output a single paper roll 200.

[0063] Furthermore, in order to guide the paper roll 200 in the storage bin 2522 smoothly into the conveying channel 2523, an inclined guide portion 2527 is formed at the bottom of the storage bin 2522, and the inclined guide portion 2527 extends upward along the connection port.

[0064] Specifically, the paper rolls 200 at the bottom of the storage bin 2522 can be neatly arranged and slid into the conveying channel 2523 via the inclined guide 2527 to ensure smooth output of the paper rolls 200.

[0065] Furthermore, since the paper roll 200 is relatively long, the paper rolls 200 stored in the storage bin 2522 are prone to crossing at the connection point, preventing them from entering the conveying channel 2523. Therefore, the supply assembly 25 also includes a toggle module 253, which includes a lever 2531, two connecting rods 2532, and a toggle drive component 2533. The lever 2531 is connected between the two connecting rods 2532. The connecting rods 2532 and the lever 2531 are located in the storage bin 2522. The upper end of the connecting rod 2532 is hinged to the inclined guide portion 2527. The lever 2531 is arranged close to the connection point and extends along the length of the connection point. The toggle drive component 2533 is configured to drive the connecting rod 2532 to rotate.

[0066] Specifically, when the paper rolls 200 near the connection port of the storage bin 2522 become blocked due to cross-interference, the paper rolls 200 at the bottom of the storage bin 2522 can be moved by the agitator module 253. The agitator drive component 2533 drives the lever 2531 to move up and down at the connection port via the connecting rod 2532, thereby agitating and sorting the paper rolls 200 at the connection port. Since the lever 2531 extends along the length of the connection port, the agitation of the lever 2531 allows the cross-intersecting paper rolls 200 to be sorted smoothly, thus solving the problem of cross-intersecting blockage and ensuring smooth output of the paper rolls 200.

[0067] Preferably, a baffle 2528 is also provided at the connection port. The baffle 2528 is located in the storage bin 2522 and is provided on the inclined guide part 2527. The baffle 2528 is located between the lever 2531 and the connection port.

[0068] Specifically, during the process of the lever 2531 moving the paper roll 200, the baffle 2528 on one side of the lever 2531 can better correct the skewed paper roll 200 to the correct posture.

[0069] The lower end of the baffle 2528 is disposed on the inclined guide portion 2527, and the upper end of the baffle 2528 forms a positioning surface, which is vertically arranged and parallel to the inner wall of the conveying channel 2523. Specifically, during the movement of the lever 2531, the paper roll 200 located between the lever 2531 and the baffle 2528 is corrected in posture, and after passing around the baffle 2528 along the top positioning surface, the baffle 2528 can further guide the paper roll 200 to slide into the connecting port below in the correct posture.

[0070] Furthermore, to meet the winding requirements of films of different specifications and sizes, the storage bin 2522 also needs to meet the supply requirements of paper rolls 200 of different lengths to improve versatility. The storage bin 2522 is also provided with an adjusting plate 254, which is vertically arranged and can slide horizontally in the storage bin 2522. The outer contour of the adjusting plate 254 matches the contour of the cross section of the storage bin 2522 perpendicular to the length direction. An extension plate 255 is also provided at the bottom of the adjusting plate 254, which extends into the conveying channel 2523.

[0071] Specifically, the adjusting plate 254 is vertically arranged in the storage bin 2522 to adjust the length of the space where the paper rolls are stored. To meet the supply requirements of paper rolls 200 of different lengths, the adjusting plate 254 can be adjusted horizontally to adjust the effective container length of the storage bin 2522. For example, the side wall of the storage bin 2522 is provided with horizontally arranged strip-shaped holes, and the adjusting plate 254 is provided with threaded holes. Bolts pass through the strip-shaped holes and are threaded into the threaded holes.

[0072] Based on the above technical solution, optionally, in order to meet the requirements of the air shaft 4 to automatically unload the film roll 100 and automatically load the paper roll 200 through the automatic loading and unloading equipment 2, the air shaft 4 is also structurally improved. The following is a detailed description in conjunction with the attached... Figures 15-17 Please provide an explanation.

[0073] The air expansion shaft 4 includes an air inflator 41 and an expansion component. The expansion component is disposed on the air inflator 41. An air inflator hole is provided on the end face of one end of the air inflator 41. An air nozzle 42 is disposed in the air inflator hole. A positioning sleeve 43 is also disposed on the air inflator 41. The positioning sleeve 43 is arranged close to the air nozzle 42.

[0074] Specifically, an air chamber is formed in the inflation / deflation shaft 41, allowing air to be injected into the air chamber through the inflation / deflation port, causing the expansion component to expand outward. Simultaneously, the air chamber can also be vented out through the inflation / deflation port, allowing the expansion component to retract. The specific manner in which the expansion component expands and contracts on the inflation / deflation shaft 41 can refer to the structural configuration of a conventional air expansion shaft 4, and is not limited here.

[0075] By configuring an inflation / deflation hole at one end of the inflation / deflation shaft 41, both inflation and deflation requirements can be met. This allows it to be used in conjunction with the automatic loading / unloading equipment 2 during operation, where inflation and deflation can be performed via the inflation / deflation component 242 of the inflation / deflation assembly 24.

[0076] The valve 42 is opened by a press, as is the case with conventional press-type valves. Thus, during inflation and deflation, the inflation / deflation component 242 abuts against the valve 42 to open it and connect it to the first vent 2421, and then inflation / deflation is performed as needed.

[0077] Meanwhile, since the air expansion shaft 4 needs to automatically put on the new paper roll 200, in order to ensure the accuracy of the paper roll 200 being put on, a positioning sleeve 43 is provided at one end of the air expansion shaft 41. The positioning sleeve 43 can position the paper roll 200 put on the air expansion shaft 41.

[0078] During the process of the new paper roll 200 being mounted on the inflation / deflation shaft 41 via the support bracket 23, the paper roll 200 will abut against the positioning sleeve 43 to ensure that the paper roll 200 is assembled in place. The positioning sleeve 43 is designed to ensure that the paper roll 200 is assembled with the required precision during the automatic mounting process, thus ensuring that the paper roll 200 can be automatically assembled in place.

[0079] Furthermore, an insertion groove 44 is provided on the end face of one end of the inflation / deflation shaft 41, and an inflation / deflation hole is provided in the insertion groove 44.

[0080] Specifically, by providing a insertion groove 44 at the end of the air expansion shaft 4, the insertion groove 44 can meet the installation requirements of the air nozzle 42, allowing it to be built into the insertion groove 44 to avoid being bumped and improve the reliability of use. On the other hand, the insertion groove 44 can guide the inflation / deflation component 242 to be accurately inserted into the interior to open the air nozzle 42.

[0081] To improve the sealing reliability of the connection, the free end of the inflation / deflation component 242 is tapered; when the air expansion shaft 4 is inflated or deflated, the free end of the inflation / deflation component 242 is sealed and inserted into the insertion groove 44.

[0082] Furthermore, during the automatic loading and unloading process of the air shaft 4, since the air shaft 4 needs to be clamped by the inflation and deflation assembly 24 of the automatic loading and unloading equipment 2 and one end is suspended in the air, in order to improve the clamping reliability of the air shaft 4, an annular positioning groove 45 is also provided on the outer surface of the inflation and deflation shaft 41, and the annular positioning groove 45 is arranged on the outside of the positioning sleeve 43.

[0083] Specifically, after the air shaft 4 is placed on the support frame 23 of the automatic loading and unloading equipment 2, the unloading plate 246 of the inflation / deflation assembly 24 will be locked in the annular positioning groove 45. At the same time, the free end of the inflation / deflation shaft 41 is clamped and fixed by the clamping component. In this way, after the support frame 23 of the automatic loading and unloading equipment 2 drives the membrane frame to detach from the air shaft 4, one end of the air shaft 4 is effectively supported by the clamping component and the unloading plate 246 to meet the requirements of attitude stability for the other end of the air shaft 4 to be suspended in the air.

[0084] In another embodiment of this application, for the film roll 100 unloaded from the automatic loading and unloading equipment 2, in order to meet the requirements of the automated design of the subsequent film wrapping and packaging process, the automatic film winding and packaging system further includes a packaging and transfer equipment 3. The packaging and transfer equipment 3 can receive the film roll 100 unloaded from the automatic loading and unloading equipment 2 and automatically wrap and package the film roll 100. The following is in conjunction with the appendix Figures 12-14 The specific structure of the packaging and transfer equipment 3 will be described.

[0085] The packaging and transfer equipment 3 includes a packaging frame 31, a support frame 32, and a film clamping assembly 33. The top of the packaging frame 31 is provided with a bearing seat 34, which is configured to support a packaging roll 35 wrapped with packaging film 300. The support frame 32 is rotatably mounted on the packaging frame 31 and is provided with at least one rotatable support roller 36, which extends along the axis of rotation of the support frame 32. The film clamping assembly 33 includes a film clamping component 331 and a film clamping lifting seat 332. The film clamping lifting seat 332 is slidably mounted on the packaging frame 31 and located above the support frame 23. The film clamping component 331 is mounted on the film clamping lifting seat 332 and is configured to clamp the packaging film 300 output from the packaging roll 35. The packaging and transfer equipment 3 is arranged on one side of the automatic loading and unloading equipment 2, and the support frame 32 is configured to receive the film roll 100 output from the support frame 23.

[0086] Specifically, in actual use, after the membrane roll 100 is detached from the air shaft 4, the support frame 23 moves with the sliding frame 22 to the support frame 32. At this time, the support frame 23 flips so that the membrane roll 100 rolls onto the support frame 32.

[0087] After the membrane roll 100 rolls onto the support frame 32, the support frame 32 can be rotated from an inclined state to a horizontal state under the driving action of the cylinder to smoothly support the membrane roll 100.

[0088] Driven by the lifting cylinder 1423, the film clamping lifting seat 332 can move downward along the packing frame 31. The film clamping component 331 on the film clamping lifting seat 332 will clamp the packaging film 300 on the packaging roll 35 and move it downward and abut against the surface of the film roll 100. Then, the support roller 36 rotates under the drive of the packing motor 37 to drive the film roll 100 on the carrier frame 32 to rotate, thereby making the packaging film 300 wrap around the surface of the film roll 100 to complete the automatic wrapping of the packaging film 300 on the surface of the film roll 100.

[0089] The support roller 36 drives the film roll 100 to rotate, and the film clamping assembly 33 clamps the packaging film 300 onto the surface of the film roll 100. As the film roll 100 rotates, it automatically wraps the packaging film 300 around its surface to achieve automatic film wrapping. In this way, the film roll 100 can be automatically wrapped and packaged after unwinding. The film roll 100 is supported and driven to rotate by the support roller 36 at the bottom, eliminating the need for manual hoisting and handling of the film roll 100 to the drive shaft, thus reducing the labor intensity of workers.

[0090] Furthermore, the film clamping component 331 includes a clamping bracket 3311, a first roller 3312, a second roller 3313, and a clamping drive component 3314. The first roller 3312 is rotatably mounted on the film clamping lifting seat 332, the second roller 3313 is rotatably mounted on the clamping bracket 3311, the clamping bracket 3311 is slidably mounted on the film clamping lifting seat 332, and the clamping drive component 3314 is configured to drive the clamping bracket 3311 to slide closer to or further away from the first roller 3312.

[0091] Specifically, in order to effectively hold the packaging film 300 and meet the requirement that the packaging film 300 automatically winds onto the film roll 100 during the rotation of the film roll 100, the packaging film 300 is clamped by the cooperation of the first roller 3312 and the second roller 3313.

[0092] A film clamping component 331 is disposed on the film clamping lifting seat 332 to convey the packaging film 300 to the surface of the film roll 100 below. At this time, the packaging film 300 is pressed between the first roller 3312 and the film roll 100, so that the head of the packaging film 300 is pressed onto the film roll 100 by the first roller 3312. During the packaging process, when the film roll 100 is driven to rotate by the support roller 36, the clamping drive component 3314 (such as a cylinder or electric push rod) drives the clamping bracket 3311 away from the first roller 3312, so that a gap is formed between the second roller 3313 and the first roller 3312, thereby allowing the packaging film 300 to be continuously conveyed onto the film roll 100 through the gap between the first roller 3312 and the second roller 3313. The film clamping lifting seat 332 can be driven to slide up and down by the film clamping lifting cylinder 3331423.

[0093] During the process of continuously winding the packaging film 300 around the surface of the film roll 100, the first roller 3312 can guide and press the packaging film 300 to reliably wind around the surface of the film roll 100, thereby improving the quality of packaging.

[0094] Furthermore, after wrapping a sufficient number of turns of packaging film 300 around the surface of film roll 100, the packaging film 300 needs to be cut. For this purpose, the packaging and transfer device 3 also includes a cutting assembly 38, which includes a cutting bracket 381, a cutter 382, ​​and a cutting drive component 383. The cutting bracket 381 is arranged laterally and mounted on the packaging frame 31. The cutter 382 is slidably mounted on the cutting bracket 381. The cutting drive component 383 is configured to drive the cutter 382 to slide on the cutting bracket 381.

[0095] Specifically, after the packaging film 300 is wound onto the film roll 100, the film clamping lifting seat 332 moves the film clamping assembly 33 above the cutting assembly 38. At this time, the packaging film 300 is stretched and arranged between the packaging roll 35 and the film roll 100, and located between the first roller 3312 and the second roller 3313. Then, the clamping drive component 3314 drives the clamping bracket 3311 to move, so that the packaging film 300 is clamped between the first roller 3312 and the second roller 3313. The cutting drive component 383 can then drive the cutter 382 to move, so as to cut the packaging film 300 between the film clamping component 331 and the film roll 100. After the packaging film 300 is cut, the head of the packaging film 300 will be exposed below the first roller 3312 and the second roller 3313, so that the head of the packaging film 300 can effectively adhere to the new film roll 100 for winding during the next packaging.

[0096] Furthermore, to prevent the packaging film 300 from being accidentally cut by the cutter 382 during the wrapping process, the cutting bracket 381 is provided with an operation window, and the operation window is provided with a flip-up cover plate 384. The cutter 382 is arranged opposite to the operation window. The cutting drive component 383 is configured to drive the cutter 382 to extend out of the operation window and push open the cover plate 384.

[0097] Specifically, when not in use, the cutter 382 retracts to one side of the operating window and is covered by a cover plate 384 to prevent the packaging film 300 from contacting the cutter 382.

[0098] Furthermore, in order to improve the rotational stability of the film roll 100, the support frame 32 is provided with two support rollers 36 arranged side by side, and the packing frame 31 is provided with a synchronous drive component 14124, which is configured to drive the two support rollers 36 to rotate synchronously.

[0099] Specifically, the synchronous drive component 14124 is powered by the packaging motor 37, and can drive the two side-by-side support rollers 36 to rotate synchronously via belts or chains, so that the film rolls 100 on the two support rollers 36 rotate smoothly.

[0100] The first roller 3312 can be arranged above the middle part of the two support rollers 36 so that the first roller 3312 can press the packaging film 300 onto the top of the film roll 100.

[0101] In addition, during the process of the support roller 36 decelerating and stopping after the film roll 100 has finished wrapping, in order to prevent the packaging roll 35 from continuing to rotate due to inertia, a brake 39 can also be provided on the packing frame 31. The brake 39 is arranged on one side of the bearing seat 34 and is configured to brake the packaging roll 35 to match the rotation speed of the support roller 36.

[0102] Based on the above technical solution, the specific control methods for the automatic film winding and packaging system during use include control procedures.

[0103] The winding machine 1 drives the air shaft 4 through the shaft drive module 13 to rotate the paper roll 200 to complete the winding of the film onto the paper roll 200 to form the film roll 100. After the winding is completed, the air shaft 4 and the film roll 100 are placed on the support frame 23 of the automatic loading and unloading equipment 2. The inflation / deflation assembly 24 of the automatic loading and unloading equipment 2 clamps the end of the air shaft 4 and connects the inflation / deflation component 242 to the inflation / deflation hole of the air shaft 4 to deflate the air shaft 4. The sliding frame 22 slides away from the inflation / deflation assembly 24 so that the support frame 23 drives the film roll 100 to disengage from the air shaft 4. The support frame 23 flips so that the film roll 100 rolls onto the support frame 32 of the packaging and transfer equipment 3. Then, the discharge port 2521 of the material box 252 opens so that the paper roll 200 falls onto the support frame 23. The sliding frame 22 moves back to its original position and so that the paper roll 200 is fitted onto the air shaft 4. The inflation / deflation component 242 inflates the air shaft 4 again. Finally, the air shaft 4 with the paper roll 200 is lifted onto the recycling machine 1 for later use by the lifting clamp. The film clamping component 331 of the packaging and transfer equipment 3 clamps the packaging film 300 and moves it downward so that the packaging film 300 is attached to the film roll 100. The support roller 36 rotates to drive the film roll 100 to rotate so that the packaging film 300 is wrapped around the film roll 100 to complete the packaging.

[0104] Specifically, after the rewinder 1 completes the automatic winding operation of the film, the paper roll 200 on the air shaft 4 is wrapped with the film and forms a film roll 100. The air shaft 4 can be lifted off the rewinder 1 by the lifting module 14 and placed on the support frame 23 in the automatic loading and unloading equipment 2 on one side.

[0105] Meanwhile, the corresponding end of the air shaft 4 is positioned between the two clamping components of the inflation / deflation assembly 24, thereby clamping and fixing the end of the air shaft 4. Then, the inflation / deflation component 242 moves toward the end of the air shaft 4 to press the air nozzle 42 at the end of the air shaft 4, thus deflating the air shaft 4. After the air shaft 4 completes the deflation operation, the sliding frame 22 can drive the support frame 23 to move so that the film roll 100 on the support frame 23 is detached from the air shaft 4. The sliding frame 22 moves the film roll 100 to one side of the packaging and transfer equipment 3, and the support frame 23 flips so that the film roll 100 rolls onto the carrier frame 32 of the packaging and transfer equipment 3, thereby completing the automatic unwinding of the film roll 100.

[0106] After receiving the film roll 100, the carrier frame 32 flips to a horizontal position so that the film roll 100 is supported by two support rollers 36. The film clamping assembly 33 lowers the packaging film 300 and presses it onto the film roll 100 through the first roller 3312. The second roller 3313 moves away from the first roller 3312 and activates the support rollers 36 to rotate the film roll 100 so that the packaging film 300 is wound around the film roll 100. After the packaging film 300 is wound a set number of times around the surface of the film roll 100, the film clamping assembly 33 rises and the second roller 3313 moves closer to the first roller 3312 to clamp the packaging film 300. Then, the cutting assembly 38 cuts the packaging film 300 between the film clamping assembly 33 and the film roll 100 to complete the automatic packaging of the film roll 100.

[0107] During the control process, after the film roll 100 is unloaded from the support frame 23, the supply component 25 puts a new paper roll 200 onto the support frame 23. The limiting pin 232 on the support frame 23 extends and clamps the paper roll 200 onto the support frame 23. Then, the sliding frame 22 moves toward the inflation / deflation component 24, and after the paper roll 200 is completely wrapped around the air expansion shaft 4, the inflation / deflation component 24 inflates the air expansion shaft 4 to complete the automatic wrapping of the paper roll 200 onto the air expansion shaft 4.

[0108] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
