[0002] Release film is a functional film with special release properties. It maintains low tack after contact with specific materials, providing process protection for adhesives, ensuring full adhesion and easy peeling. Its production often involves equipment such as winding machines and unwinding machines. A winding machine is an industrial device that winds materials such as film, paper, fabric, plastic, and metal coils into rolls. It is widely used at the end of production lines in industries such as printing, packaging, plastic film, papermaking, textiles, and metallurgy. It achieves winding through the rotation of a winding shaft, and its core lies in the precise control of material tension to avoid material slack or overstretching.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] This invention provides, for example Figure 1-7 The diagram shows a high-efficiency winding machine based on release film production, used for film winding. It includes a frame 1, on which multiple guide rollers 2 and a tensioning module 3 are rotatably mounted. The tensioning module 3 is equipped with a tensioning roller 4, a cutter 8, and a drive roller 9, and a power source for driving the drive roller 9. Two symmetrically distributed rotating disks 5 are rotatably mounted on the frame 1. Between the two rotating disks 5, two detachable winding rollers 6 and two intermediate transfer rollers 33 are rotatably mounted, arranged in a circular array. Support members 7 are provided at the bottom of the winding rollers 6 furthest from the tensioning module 3 and at the top of the winding rollers 6 closest to the tensioning module 3. The support members 7 are fixedly mounted on the rotating disks 5 and rotatably connected to the winding rollers 6. A horizontal module 10 is also slidably mounted on the frame 1, on which a compression roller 11 is rotatably mounted. In actual operation; as... Figure 4As shown, the take-up roller 6, which is away from the tension module 3, rotates to take up the film. When the take-up roller 6 is fully wound, it stops rotating, and the cutter 8 cuts the film. The operator removes the fully wound take-up roller 6 and puts in the take-up roller 6 with adhesive. At the same time, the power source drives the drive roller 9 to rotate, causing the film to move towards the take-up roller 6 and fall vertically under the action of gravity. When the film falls between the extrusion roller 11 and the take-up roller 6 near the tension module 3, the horizontal module 10 drives the extrusion roller 11 to press the film onto the take-up roller 6. Then the take-up roller 6 rotates to rotate the film a predetermined number of times and then stops. After that, the rotating disk 5 rotates, rotating the take-up roller 6 with the film just wound to the position where it was just put into the take-up roller 6, that is, the position away from the tension module 3. At this time, the film will travel along the guide roller 2, tension roller 4, drive roller 9, and transfer roller 33 and be wound onto the take-up roller 6, completing the automatic installation of the film and the take-up roller 6.

[0033] To facilitate quick assembly and disassembly of the take-up roller 6, connectors 12 are fixedly installed on opposite sides of the two rotating disks 5. A rotating shaft 13 is rotatably mounted within each connector 12. A telescopic rod 14, penetrating the disk and rotating shaft 13, is slidably mounted within the rotating shaft 13. A male head 15 is fixedly mounted at the end of the telescopic rod 14. The male head 15 includes a first connector 151, a ring-shaped array of retaining strips 152 at the end of the first connector 151, and a groove 153 at the end of the male head 15. A female head 16, cooperating with the male head 15, is fixedly mounted at the end of the take-up roller 6. The female head 16 includes a second connector 161, a groove 162 on the outer circumference of the second connector 161 that mates with the retaining strips 152, and a protrusion 163 fixedly mounted at the end of the second connector 161 that mates with the groove 153. Bearings 31 are fixedly mounted at both ends of the take-up roller 6. The support member 7 has a support groove 32 at one end that mates with the bearing 31. The other end of the telescopic rod 14 is fixedly mounted with a long strip-shaped transmission member 18. The two ends of the transmission member 18 are respectively fixedly connected to the output ends of two hydraulic cylinders 17 fixedly mounted on the connector 12. As the output shaft of the hydraulic cylinder 17 extends, it will drive the two telescopic rods 14 away from each other through the transmission member 18, so that the female head 16 and the male head 15 separate. This allows the take-up roller 6 supported by the support member 7 to no longer be limited. At this time, the fully wound take-up roller 6 can be removed. The operator places the new take-up roller 6 on the support member 7, so that the bearing 31 is located in the support groove 32. Then the output shaft of the hydraulic cylinder 17 shortens, drives the locking strip 152 to insert into the locking groove 162, and inserts the protrusion 163 into the groove 153, thereby limiting the take-up roller 6 and enabling the quick assembly and disassembly of the take-up roller 6.

[0034] To ensure stable transmission even after the take-up roller 6 is rotated 180° by the rotating disk 5, and unlike existing technologies where the motor is directly mounted on the rotating disk 5 to drive the take-up roller 6, this invention avoids directly mounting the motor on the rotating disk 5 to drive the take-up roller 6. In this invention, the rotating disk 5... Figure 3As shown, it rotates continuously clockwise, which can cause the motor wiring to become tangled. Therefore, a connecting shaft 25 is rotatably installed between the frame 1 and the connecting piece 12. An external gear ring 19 is fixedly installed on the rotating disk 5. A first motor 20 and a second motor 21 are also fixedly installed on the frame 1 on one side of the rotating disk 5. A first gear 22 is fixedly installed at the end of the output shaft of the first motor 20. A second gear 23 meshes between the first gear 22 and the external gear ring 19. A first pulley 24 is fixedly installed at the end of the output shaft of the second motor 21. A second pulley 26 and a third pulley 27 are also fixedly installed on the connecting shaft 25. A fourth pulley 28 is fixedly installed on the rotating shaft 13 at one end of one take-up roller 6. A fourth pulley 28 is also fixedly installed on the drive shaft at the other end of the other take-up roller 6. A first transmission belt 29 is installed on the first pulley 24 and the second pulley 26. A second transmission belt 30 is installed between the third pulley 27 and the adjacent fourth pulley 28. Both the first transmission belt 29 and the second transmission belt 30 are synchronous toothed belts. When the output shaft of the first motor 20 rotates, it drives the first gear 22. 22 drives the external gear ring 19 to rotate via the second gear 23. The external gear ring 19 drives the rotating disk 5 to rotate. When the rotating disk 5 rotates, it drives the transmission shaft to rotate via the connecting piece 12. The transmission shaft drives the fourth pulley 28 to rotate 180° around the rotating disk 5. At this time, the fourth pulley 28 and the second transmission belt 30 work together to swing from one side to the other. At this time, the output shaft of the second motor 21 rotates. The output shaft of the second motor 21 drives the first pulley 24 to rotate. The first pulley 24 drives the second pulley 26 to rotate via the first transmission belt 29. The second pulley 26 drives the third pulley 27 to rotate via the connecting shaft 25. The third pulley 27 drives the fourth pulley 28 to rotate via the second transmission belt 30. The fourth pulley 28 drives the telescopic rod 14 to rotate via the transmission shaft. The telescopic rod 14 drives the male head 15 to rotate. The male head 15 drives the take-up roller 6 to rotate via the female head 16, thereby completing the take-up action. No matter how many times the rotating disk 5 rotates, it will not affect the wiring layout of the first motor 20 and the second motor 21, nor will it affect the quick assembly and disassembly of the take-up roller 6.

[0035] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
