Technical Field

[0001] This utility model relates to the field of PET film production, and in particular to a winding device for PET film production. Background Technology

[0002] PET film, also known as high-temperature resistant polyester film, possesses excellent physical and chemical properties, dimensional stability, transparency, and recyclability. Due to its superior mechanical properties, chemical stability, and high transparency, PET film is widely used in many fields such as packaging, electronics, optics, and construction. During PET film production, a winding device is required to wind it up for convenient subsequent processing.

[0003] A search of Chinese patents revealed publication number CN216272308U, which discloses a winding device for PET protective film production. The device includes two side plates, with bases on the bottom side walls of each side plate. A control box is located on one side wall of each side plate, and several guide shafts are positioned between the walls of the two control boxes. A winding shaft is located between the other side walls of the two side plates. A limiter is located on the front wall of each side plate, and a protective mechanism is located on one side wall of each side plate. This invention relates to the field of PET protective film winding equipment. The retractable protective mechanism facilitates protection of the winding shaft during operation. Furthermore, the adjustable telescopic plate allows for adjustment of the second protective plate's position according to different production requirements. When not in use, the second protective plate can be folded and stored.

[0004] Existing winding devices are inconvenient for installing and disassembling the winding rollers. After the PET film is wound up, the winding rollers need to be completely disassembled before the wound PET film can be unloaded. After unloading, the winding rollers need to be reinstalled. Common winding rollers are usually fixed by bolts and other components, which is inconvenient to install and disassemble, complicated and time-consuming, and greatly affects the production efficiency of PET film. In order to solve the above problems, we propose a winding device for PET film production. Utility Model Content

[0005] The purpose of this invention is to provide a winding device for PET film production, which has the advantage of facilitating the assembly and disassembly of the winding rollers.

[0020] The present invention is further configured such that a pressing block is bolted to one end of the double-sided toothed rod.

[0021] By adopting the above technical solution, the double-sided toothed rod can be easily moved by setting up a pressing block.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model allows for the simultaneous pressing of two pressing blocks, which causes the double-sided toothed rod to drive the gear to rotate. The rotation of the gear drives the snap-fit ​​toothed plate to move and disengage from the snap-fit ​​hole. Under the action of the second spring, the slide rod drives the first fixed head to disengage from one end of the take-up roller, thus facilitating the disassembly of the take-up roller. This method can achieve the purpose of facilitating the assembly and disassembly of the take-up roller, reducing workload, and improving work efficiency.

[0024] 2. This utility model rotates the screw by rotating the rotating head, which in turn moves the pressure plate. The pressure plate compresses the first spring, changing its elastic force and thus altering the clamping force of the clamping toothed rod. This allows for adjustment of the clamping force of the clamping toothed rod, ensuring stability and ease of use. Furthermore, removing the clamping head facilitates maintenance of the first spring.

One end of the slide rod 4 is rotatably connected to a first fixing head 5. A winding roller 6 is slidably sleeved on the inner wall of the first fixing head 5. A fixing block 7 is slidably sleeved on the surface of the slide rod 4 and bolted to the surface of the support plate 2. Double-sided toothed rods 8 are slidably sleeved on the inner walls of the top and bottom of the fixing block 7. Gears 9 mesh on both sides of the double-sided toothed rod 8 and are engaged with the inner walls of the fixing block 7. The gear 9 is rotatably connected to a locking toothed rod 10. The slide rod 4 has a locking hole 11 on its surface, and the locking toothed rod 10 engages with the locking hole 11. One end of the locking toothed rod 10 is provided with a first spring 12. By pressing the two pressing blocks 24 simultaneously, the double-sided toothed rod 8 drives the gear 9 to rotate. The rotation of the gear 9 drives the locking toothed plate to move and disengage from the locking hole 11. Under the action of the second spring 22, the slide rod 4 drives the first fixed head 5 to disengage from one end of the winding roller 6. This method of disassembling the winding roller 6 facilitates the installation and removal of the winding roller 6, reduces workload, and improves work efficiency.

[0034] refer to Figure 2 and Figure 3The drive mechanism 3 includes a motor 18, which is bolted to the surface of the right support plate 2. The output end of the motor 18 is bolted to a second fixing head 19, and the second fixing head 19 is slidably sleeved with the other end of the winding roller 6. By setting the drive mechanism 3, it is convenient to wind up the PET film.

[0035] refer to Figure 4 The top and bottom of the slide rod 4 are both bolted with a second slider 20. The surface of the second slider 20 is slidably connected with a second groove 21, and the second groove 21 is opened on the inner wall of the support plate 2. By setting the second slider 20 and the second groove 21, the slide rod 4 is prevented from rotating and shifting, thus improving stability.

[0036] refer to Figure 1 and Figure 2 The surface of the slide bar 4 is fitted with a second spring 22. By setting the second spring 22, it is easy to separate the first fixed head 5 from the winding roller 6, and to facilitate the disassembly of the winding roller 6.

[0037] refer to Figure 4 One end of the snap-fit ​​toothed rod 10 is wedge-shaped. By setting one end of the snap-fit ​​toothed rod 10 to be wedge-shaped, it is easy to fix the slide rod 4 and facilitate the installation of the winding roller 6.

[0038] Example 2:

[0039] refer to Figure 2 , Figure 4 and Figure 5 The inner wall of the fixing block 7 is threaded with an end cap 13, and the inner wall of the end cap 13 is threaded with a screw 14. The inner end of the screw 14 is rotatably connected to a pressure plate 15, and the first spring 12 is located between the pressure plate 15 and the snap-fit ​​toothed rod 10. Two first sliders 16 are bolted to the surface of the pressure plate 15, and the surface of the first sliders 16 is slidably connected with a first groove 17, which is opened on the inner wall of the fixing block 7. By rotating the rotating head 23, the screw 14 is rotated, and the rotation of the screw 14 causes the pressure plate 15 to move. The movement of the pressure plate 15 compresses the first spring 12, changing the elastic force of the first spring 12, thereby changing the snap-fit ​​force of the snap-fit ​​toothed rod 10. This allows for adjustment of the snap-fit ​​force of the snap-fit ​​toothed rod 10, ensuring stability and ease of use. Removing the pressure plate 14 facilitates maintenance of the first spring 12 and further enhances its usability.

[0041] refer to Figure 4 One end of the double-sided toothed rod 8 is bolted with a pressing block 24, which facilitates the movement of the double-sided toothed rod 8.

[0042] Brief description of the usage process: Fix the PET film onto the take-up roller 6, turn on the motor 18, the motor 18 rotates and drives the second fixing head 19 to rotate, the second fixing head 19 rotates and drives the take-up roller 6 to rotate, winding the PET film. When changing rollers after winding, hold the take-up roller 6 with one hand, and press the top and bottom pressing blocks 24 with the other hand at the same time. The pressing block 24 moves and drives the double-sided toothed rod 8 to move, the double-sided toothed rod 8 moves and drives the gear 9 to rotate, the gear 9 rotates and drives the locking toothed rod 10 to move, so that the locking toothed rod 10 disengages from the locking hole 11. The slide rod 4 drives the first fixing head 5 to move under the action of the second spring 22, so that the first fixing head 5 disengages from one end of the take-up roller 6. Then remove the other end of the take-up roller 6 from the second fixing head 19 to complete the disassembly. When installing, insert one end of the take-up roller 6 into the second fixing head 19, and then insert the other end of the take-up roller 6 into the first fixing head 19. Align the fixed head 5, move the slide bar 4. The movement of the slide bar 4 drives the first fixed head 5 to move, so that the other end of the take-up roller 6 is inserted into the first fixed head 5, fixing the take-up roller 6. At the same time, the locking tooth 10 engages with the locking hole 11 under the action of the first spring 12, fixing the slide bar 4 and completing the installation, thereby facilitating the installation and removal of the take-up roller 6. Rotate the rotating head 23, which drives the screw 14 to rotate. The rotation of the screw 14 causes the screw 14 to move the pressure plate 15. The movement of the pressure plate 15 changes the elastic force of the first spring 12. The change in the elastic force of the first spring 12 changes the locking force between the locking tooth 10 and the locking hole 11, thereby adjusting the locking force of the locking tooth 10. By rotating the end cover 13, the end cover 13 can be removed, then the pressure plate 15 can be removed, and finally the first spring 12 can be removed, which facilitates the maintenance and replacement of the first spring 12 and improves practicality.
