Technical Field
[0001] This application relates to the field of composite film processing equipment technology, and in particular to a flattening device for an easily peelable composite film. Background Technology
[0002] Currently, composite films are widely used in packaging, electronics, medical and other fields. Their production process requires the lamination and flattening of multiple layers of film.
[0003] Currently, most methods for flattening composite films suffer from the drawback of not being able to perform multi-stage transmission for multiple functional layers. This limitation not only restricts the flexibility and efficiency of the production process but also invisibly increases production costs. Specifically, the lack of a multi-stage transmission mechanism means that when processing multi-layer composite films with different functional characteristics, it is necessary to use independent flattening equipment or complex adjustment steps to ensure that each layer achieves the expected flattening effect. This approach not only increases equipment investment and maintenance costs and reduces overall production efficiency but also brings many inconveniences to users. Utility Model Content
[0004] The purpose of this application is to provide a flattening device for easily peelable composite films, which has the advantages of multi-stage transmission and solves the problems mentioned in the background art.
[0005] The flattening device for an easy-to-peel composite film provided in this application adopts the following technical solution: it includes a support platform, a flattening assembly, a pressing assembly, and a winding assembly. The flattening assembly includes a drive motor fixedly mounted on the side of the support platform via a mounting plate. First bearings are fixedly connected to both sides of the inner wall of the support platform. First rotating shafts are rotatably connected inside the two first bearings. One end of one of the first rotating shafts is fixedly connected to the output shaft of the drive motor. Flattening rollers are fixedly connected to one end of both first rotating shafts. The flattening assembly includes a second bearing and a third bearing fixedly connected to both sides of the inner wall of the support platform. A second shaft is rotatably connected inside each of the two second bearings. An upper flattening roller is fixedly connected to one end of each of the two second shafts. A first pulley is fixedly connected to the surface of each of the first and second shafts. A first rubber belt is driven between the two first pulleys. A third shaft is rotatably connected inside each of the two third bearings. A lower flattening roller is fixedly connected to one end of each of the two third shafts. A second pulley is fixedly connected to the surface of each of the second and third shafts. A second rubber belt is driven between the two second pulleys. The winding assembly includes a fourth bearing fixedly connected to both sides of the inner wall of the support platform. A fourth shaft is rotatably connected inside each of the two fourth bearings. A concave plate is fixedly connected to one end of each of the two fourth shafts. A winding roller overlaps on both sides of the two concave plates. A third pulley is fixedly connected to the surface of both the third shaft and the fourth shaft. A third rubber belt is drivingly connected between the two third pulleys. By adopting the above technical solution, and by setting up a flattening assembly, a pressing assembly, and a winding assembly, a multi-stage transmission effect can be achieved using a first rubber belt, a second rubber belt, and a third rubber belt. During the pressing operation, after the drive motor starts, it drives the first rotating shaft fixedly connected to it to rotate, thereby causing the flattening roller to rotate and initially flatten and transport the composite film. At the same time, the first pulley on the first rotating shaft drives the second rotating shaft to rotate via the first rubber belt, thereby causing the upper pressing roller to work and perform the first flattening of the composite film. Then, the second pulley on the second rotating shaft drives the third rotating shaft to rotate via the second rubber belt, causing the lower pressing roller to flatten the composite film. The second flattening process achieves a multi-stage flattening effect, making it easier to peel off. Finally, the third pulley on the third shaft drives the fourth shaft to rotate via the third rubber belt, which in turn causes the winding roller to rotate and wind up the flattened composite film. This structure can simultaneously perform efficient and continuous flattening operations on multi-layer composite films with different functional characteristics, improving the flexibility and efficiency of the production process, reducing equipment investment and maintenance costs, and enhancing overall production efficiency. After the composite film undergoes the above multi-stage flattening process, the bonding between its layers is tighter and more uniform, effectively avoiding the problems of delamination and peeling difficulties during subsequent use or processing.
[0006] Preferably, a plurality of support legs are fixedly connected to the bottom of the support platform, and a base is fixedly connected to the bottom of each support leg; By adopting the above technical solution and setting up support legs and a base, a stable and reliable support can be provided for the entire device, ensuring that the device will not shake or shift during the flattening operation, thereby guaranteeing the accuracy and quality of the flattening operation.
[0007] Preferably, fastening plates are fixedly connected to the sides of several of the support legs; By adopting the above technical solution and setting a fastening plate, the stability of the support leg can be enhanced. When the device is subjected to external force during operation, the fastening plate can effectively prevent the support leg from deforming or loosening.
[0008] Preferably, a support frame is fixedly connected to the side of the support platform, a storage box is placed inside the support frame, and handles are fixedly connected to both sides of the storage box; By adopting the above technical solution, and by setting up a support frame, a storage box, and a handle, the storage box can properly store the winding roller of the composite film, which not only facilitates subsequent retrieval and management, but also avoids damage or chaos that may be caused by the winding roller being placed randomly. At the same time, the handle makes it easier and more convenient to carry and move the storage box, while the support frame can provide stable support for the storage box.
[0009] Preferably, the concave plate is internally threadedly connected to the take-up roller with screws; By adopting the above technical solution and by setting screws, the take-up roller can be easily disassembled and replaced. After the winding of the composite film on the current take-up roller is completed, the take-up roller can be quickly disassembled for subsequent storage.
[0010] Preferably, two limiting discs are fixedly connected to the surface of the take-up roller; By adopting the above technical solution and setting a limiting plate, the composite film can be limited during winding to prevent it from shifting during the winding process, thus ensuring the neatness and standardization of the winding.
[0011] Preferably, the top of the support platform is made of polytetrafluoroethylene; By adopting the above technical solution and setting the top material of the support platform to be polytetrafluoroethylene, the friction between the composite membrane and the support platform can be reduced, making the composite membrane smoother during the flattening process and avoiding scratches or damage to the surface of the composite membrane due to excessive friction, thus ensuring the quality of the composite membrane.
[0012] Preferably, the surface of the take-up roller is provided with an adhesive layer; By adopting the above technical solution and setting an adhesive layer, the starting end of the composite film can be better fixed during winding, preventing it from slipping or shifting in the early stage of winding, and ensuring that the winding work can be carried out smoothly and stably.
[0013] In summary, this application includes at least one of the following beneficial technical effects: This easy-to-peel composite film flattening device, by setting up a flattening component, a pressing component, and a winding component, can achieve a multi-stage transmission effect using a first rubber belt, a second rubber belt, and a third rubber belt. During the flattening operation, after the drive motor starts, it drives the first rotating shaft fixedly connected to it to rotate, thereby causing the flattening roller to rotate and initially flatten and transport the composite film. At the same time, the first pulley on the first rotating shaft drives the second rotating shaft to rotate via the first rubber belt, thereby causing the upper pressing roller to work and flatten the composite film for the first time. Then, the second pulley on the second rotating shaft drives the third rotating shaft to rotate via the second rubber belt, causing the lower pressing roller to flatten the composite film. A second flattening process is performed to achieve a multi-stage flattening effect, making it easier to peel off. Finally, the third pulley on the third shaft drives the fourth shaft to rotate via the third rubber belt, which in turn causes the winding roller to rotate and wind up the flattened composite film. This structure can simultaneously perform efficient and continuous flattening operations on multi-layer composite films with different functional characteristics, improving the flexibility and efficiency of the production process, reducing equipment investment and maintenance costs, and improving overall production efficiency. After the composite film undergoes the above multi-stage flattening process, the bonding between its layers is tighter and more uniform, effectively avoiding the problems of delamination and peeling difficulties in subsequent use or processing.

Detailed Implementation
[0016] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.
[0017] Example 1: A flattening device for an easily peelable composite film, referring to... Figure 1 , Figure 3 , Figure 4 and Figure 5 The system includes a support platform 1, a flattening assembly 2, a pressing assembly 3, and a winding assembly 4. The flattening assembly 2 includes a drive motor 201 fixedly mounted on the side of the support platform 1 via a mounting plate. Both sides of the inner wall of the support platform 1 are fixedly connected to first bearings 202. The interior of each of the two first bearings 202 is rotatably connected to a first rotating shaft 203. One end of one of the first rotating shafts 203 is fixedly connected to the output shaft of the drive motor 201. One end of each of the two first rotating shafts 203 is fixedly connected to a flattening roller 204. The flattening assembly 3 includes a second bearing 301 and a third bearing 303 fixedly connected to both sides of the inner wall of the support platform 1. A second shaft 302 is rotatably connected inside each of the two second bearings 301. An upper flattening roller 305 is fixedly connected to one end of each of the two second shafts 302. A first pulley 11 is fixedly connected to the surface of the first shaft 203 and the second shaft 302. A first rubber belt 12 is driven between the two first pulleys 11. A third shaft 304 is rotatably connected inside each of the two third bearings 303. A lower flattening roller 306 is fixedly connected to one end of each of the two third shafts 304. A second pulley 13 is fixedly connected to the surface of the second shaft 302 and the third shaft 304. A second rubber belt 14 is driven between the two second pulleys 13. The winding assembly 4 includes fourth bearings 401 fixedly connected to both sides of the inner wall of the support platform 1. Each of the two fourth bearings 401 has a fourth rotating shaft 402 rotatably connected inside. One end of each of the two fourth rotating shafts 402 is fixedly connected to a concave plate 403. A winding roller 404 overlaps on both sides of the two concave plates 403. A third pulley 15 is fixedly connected to the surfaces of the third rotating shaft 304 and the fourth rotating shaft 402. A third rubber belt 16 is connected between the two third pulleys 15. By setting up the flattening assembly 2, the pressing assembly 3, and the winding assembly 4, a multi-stage transmission effect can be achieved using the first rubber belt 12, the second rubber belt 14, and the third rubber belt 16. During the pressing operation, after the drive motor 201 starts, it drives the first rotating shaft 203 fixedly connected to it to rotate, thereby causing the flattening roller 204 to rotate and initially flatten and transport the composite film. Simultaneously, the first pulley 11 on the first rotating shaft 203 drives the fourth rotating shaft 404 through the first rubber belt 12. The rotation of the second shaft 302 causes the upper flattening roller 305 to work, performing the first flattening of the composite film. Then, the second pulley 13 on the second shaft 302 drives the third shaft 304 to rotate via the second rubber belt 14, causing the lower flattening roller 306 to perform the second flattening of the composite film, achieving a multi-stage flattening effect and making it easy to peel. Finally, the third pulley 15 on the third shaft 304 drives the fourth shaft 402 to rotate via the third rubber belt 16, causing the winding roller 404 to rotate and wind up the flattened composite film. This structure can perform efficient and continuous flattening operations on multi-layer composite films with different functional characteristics at the same time, improving the flexibility and efficiency of the production process, reducing equipment investment and maintenance costs, and improving overall production efficiency. After the composite film undergoes the above multi-stage flattening process, the bonding between its layers is tighter and more uniform, effectively avoiding the problems of delamination and peeling difficulties in subsequent use or processing.
[0018] Please see Figure 1 The bottom of the support platform 1 is fixedly connected to several support legs 5, and the bottom of the support legs 5 is fixedly connected to a base 6. By setting the support legs 5 and the base 6, a stable and reliable support can be provided for the entire device, ensuring that the device will not shake or shift during the flattening operation, thereby ensuring the accuracy and quality of the flattening operation. The sides of several support legs 5 are fixedly connected to fastening plates 7. By setting fastening plates 7, the stability of the support legs 5 can be enhanced. When the device is subjected to external force during operation, the fastening plates 7 can effectively prevent the support legs 5 from deforming or loosening.
[0019] Please see Figure 2 and Figure 5A support frame 8 is fixedly connected to the side of the support platform 1. A storage box 9 is placed inside the support frame 8. Handles 10 are fixedly connected to both sides of the storage box 9. By setting up the support frame 8, the storage box 9 and the handles 10, the storage box 9 can properly store the winding roller 404 of the composite film. This not only facilitates subsequent retrieval and management, but also avoids damage or chaos that may be caused by the winding roller 404 being placed randomly. At the same time, the handles 10 make it easier and more convenient to carry and move the storage box 9. The support frame 8 can provide stable support for the storage box 9. The concave plate 403 is connected to the internal thread of the winding roller 404 by screws 17. By setting the screws 17, it is easy to disassemble and replace the winding roller 404. After the winding of the composite film on the current winding roller 404 is completed, the winding roller 404 can be quickly disassembled for subsequent storage.
[0020] Please see Figure 5 , Figure 6 and Figure 7 Two limiting discs 18 are fixedly connected to the surface of the take-up roller 404. By setting the limiting discs 18, the composite film can be limited during take-up to prevent the composite film from shifting during the take-up process, ensuring the neatness and standardization of the take-up. The top material of the support platform 1 is polytetrafluoroethylene 19. By setting the top material of the support platform 1 to polytetrafluoroethylene 19, the friction between the composite film and the support platform 1 can be reduced, making the composite film smoother during the flattening process and avoiding scratches or damage to the surface of the composite film due to excessive friction, thus ensuring the quality of the composite film. The surface of the take-up roller 404 is provided with an adhesive layer 20. By setting the adhesive layer 20, the starting end of the composite film can be better fixed during take-up, preventing it from sliding or shifting in the early stage of take-up, ensuring that the take-up operation can be carried out smoothly and stably.
[0021] The implementation principle of this application embodiment is as follows: First, the operator checks the status of each component of the device to ensure that there are no impurities on the surface of the flattening roller 204, the upper pressure flattening roller 305, and the lower pressure flattening roller 306. Then, the winding roller 404 is securely attached to the concave plate 403 by screws 17, and the adhesive layer 20 on the surface of the winding roller 404 is intact. At the same time, it is confirmed that the bottom support leg 5 of the support platform 1 and the base 6 are placed stably, the fastening plate 7 is not loose, and the storage box 9 has been placed in the support frame 8, so as to make basic preparations for subsequent operations. Then, one end of the flattened easy-peel composite film is pulled to the take-up roller 404. The adhesive layer 20 on the surface of the take-up roller 404 is used to fix the starting end of the composite film to prevent slippage in the early stage of winding. Then, the drive motor 201 is started, and its output shaft drives the first rotating shaft 203 fixedly connected to it to rotate. Subsequently, the first rotating shaft 203 is stably rotated by the support of the first bearing 202, and the power transmission process is started. Then, when the first rotating shaft 203 rotates, it synchronously drives the flattening rollers 204 at both ends to rotate. Then, the flattening rollers 204 perform preliminary stretching and flattening on the pulled composite film to eliminate wrinkles on the film surface. During this process, the polytetrafluoroethylene 19 material on the top of the support platform 1 greatly reduces the friction between the composite film and the platform, ensuring smooth transport of the composite film and avoiding scratches or damage to the film surface due to friction. Subsequently, the initially flattened composite film continues to be conveyed to the flattening assembly 3. At this time, the first pulley 11 on the surface of the first rotating shaft 203 drives the second rotating shaft 302 to rotate through the first rubber belt 12, which in turn drives the upper flattening roller 305 to rotate, flattening the composite film for the first time, so that the layers of the composite film are initially bonded. Then, the second pulley 13 on the surface of the second rotating shaft 302 drives the third rotating shaft 304 to rotate through the second rubber belt 14, and the lower flattening roller 306 rotates accordingly, flattening the composite film for the second time. Through multi-stage flattening, the film layers are tightly and evenly bonded, meeting the requirements for easy peeling characteristics. Afterwards, the composite film that has undergone multi-stage flattening is conveyed to the winding assembly 4. The third pulley 15 on the surface of the third rotating shaft 304 drives the fourth rotating shaft 402 to rotate via the third rubber belt 16. Then, the concave plate 403 rotates synchronously with the fourth rotating shaft 402, thereby driving the winding roller 404 to rotate. During the winding process, the limiting discs 18 on both sides of the winding roller 404 limit the composite film to prevent the composite film from shifting and ensure the neatness of the winding. At the same time, the adhesive layer 20 continuously fixes the film body to ensure stable winding. Finally, when the composite film on the take-up roller 404 reaches the preset take-up amount, turn off the drive motor 201 and stop the operation of all components. Then, the operator unscrews the screw 17 connecting the concave plate 403 and the take-up roller 404, removes the take-up roller 404 with the composite film wound up, and puts it into the storage box 9 on the support frame 8.
