Description

Technical Field

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

[0002] A search of Chinese patents revealed CN214988969U, a device for winding antistatic plastic film. The device comprises a support mechanism whose tail end is fixedly connected to a base. A lifting mechanism is mounted on the base at the midpoint of the support mechanism's connection point. A support roller is mounted on the lifting mechanism via a U-shaped bracket. A coating roller is rotatably mounted on the support mechanism, and the support roller and coating roller are arranged parallel to each other. The coating roller has a hollow structure with evenly spaced liquid outlet holes on its side wall. A wetting layer is installed on the coating roller. A storage tank and a circulation pump are both installed inside the base. The outlet of the storage tank is connected to the inlet of the coating roller via an inlet pipe, and the outlet of the coating roller is connected to the inlet of the storage tank via an outlet pipe and the circulation pump. Both the inlet and outlet pipes are located within the support mechanism. This improvement in the storage tank's location effectively prevents the antistatic liquid from leaking out from the gap between the storage tank and the wetting cloth, thus avoiding contamination of the working environment.

[0003] Existing winding devices suffer from poor winding quality. Generally, these devices directly wind the plastic film, resulting in low tension during winding and a loose winding on the surface of the winding roller. This leads to a large, easily scattered, and poorly wound film, making it inconvenient to use and replace. After winding the plastic film, the roller needs to be removed, but since winding rollers are typically bolted, replacement requires tools, which is cumbersome, increases workload, and reduces efficiency. To address these problems, we propose a plastic film winding device. Utility Model Content

A first spring 11 is provided between the pressure plate 10 and the slide plate 9. A friction block 12 is bolted to the surface of the pressure plate 10. Friction discs 13 are fixedly sleeved at both ends of the tension roller 4, and the surfaces of the friction discs 13 and the friction blocks 12 are in contact. The friction between the friction blocks 12 and the friction discs 13 causes the tension roller 4 to generate resistance, thereby tightening and winding the plastic film. This method can achieve good winding quality and is convenient to use. By rotating the rotating head 29, the friction force between the friction blocks 12 and the friction discs 13 can be changed, and the resistance during winding can be adjusted, thereby improving practicality and applicability.

[0034] refer to Figure 2 The surfaces of the pressure plate 10 and the slide plate 9 are both bolted with sliders 26. The surface of the sliders 26 is slidably connected with a groove 27, and the groove 27 is opened on the inner wall of the fixed shell 5. By setting the sliders 26 and the grooves 27, the pressure plate 10 and the slide plate 9 are prevented from shifting, thus improving stability.

[0035] refer to Figure 2 A guide rod 28 is bolted to the surface of the slide plate 9, and the guide rod 28 is slidably sleeved with the inner wall of the pressure plate 10. The first spring 11 is sleeved on the surface of the guide rod 28. By setting the guide rod 28, the first spring 11 is fixed, thereby improving the stability of the first spring 11.

[0036] refer to Figure 1 and Figure 2 One end of the bidirectional lead screw 6 is bolted with a rotating head 29, which facilitates the rotation of the bidirectional lead screw 6.

[0037] Example 2:

[0038] refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 A motor 14 is bolted to the surface of the support plate 2. Two rotating shafts 15 are arranged between the support plates 2. The left rotating shaft 15 is rotatably sleeved with the inner wall of the support plate 2, and one end of the right rotating shaft 15 is connected to the output end of the motor 14 through a coupling. A fixing groove 16 is opened on the surface of the rotating shaft 15, and a winding roller 17 is locked between the fixing grooves 16. A limit ring 18 is fixedly sleeved on the surface of the rotating shaft 15. A slide cylinder 19 is slidably sleeved on the surface of the rotating shaft 15. A second spring 20 is fixedly connected between the slide cylinder 19 and the limit ring 18 through a spring fixing member. A snap-fit ​​hole 21 is opened on the inner wall of the slide cylinder 19. A push plate 22 is slidably connected to the inner wall of 21, and a pressing rod 23 is bolted to the surface of the push plate 22. A snap-fit ​​connector 24 is slidably sleeved on the inner wall of the rotating shaft 15, and the snap-fit ​​connector 24 is adapted to the snap-fit ​​hole 21. A third spring 25 is provided between the snap-fit ​​connector 24 and the inner wall of the rotating shaft 15. By moving the slide cylinder 19, the slide cylinder 19 is disengaged from the fixing groove 16. Under the action of the third spring 25, the snap-fit ​​connector 24 snaps into the snap-fit ​​hole 21 to fix the slide cylinder 19. Then, the take-up roller 17 is taken out from the fixing groove 16 for replacement. This method can facilitate replacement, reduce workload, and improve replacement efficiency.

[0039] refer to Figure 6 One end of the snap-fit ​​connector 24 is wedge-shaped with a wedge angle of 30°-60°. By setting one end of the snap-fit ​​connector 24 to be wedge-shaped, it is easy to fix the slide cylinder 19.

[0040] refer to Figure 6The surface of the slide cylinder 19 is provided with anti-slip texture 30, which is a diagonal knurled pattern with a spacing of 2mm. The anti-slip texture 30 is provided to prevent the hand from slipping and to facilitate operation.

[0041] refer to Figure 5 and Figure 6 One end of the pressing rod 23 is bolted with a pressing head 31, and the pressing head 31 is slidably sleeved with the inner wall of the slide cylinder 19. By setting the pressing head 31, it is easy to move the push plate 22.

[0042] Brief description of the usage process: The plastic film is passed through the tension rollers 4 and then fixed onto the take-up roller 17. The motor 14 rotates, driving the shaft 15 to rotate, which in turn causes the take-up roller 17 to rotate, thus winding the plastic film and achieving the purpose of winding. The friction block 12 contacts the friction disc 13 under the action of the first spring 11, increasing the rotational resistance of the tension roller 4, thereby increasing the resistance of the plastic film when passing through the tension roller 4. During winding, the plastic film can be tightly wound onto the take-up roller 17, thus achieving the purpose of good winding quality. By rotating the rotating head 29, the rotating head 29 drives the bidirectional lead screw 6 to rotate, which in turn drives the sliding block 7 to move in opposite directions or relative to each other. The movement of the sliding block 7 in opposite directions or relative to each other drives the support rod 8 to move in opposite directions or relative to each other, which in turn drives the slide plate 9 to move. The movement of the first spring 11 changes its elastic force, which in turn changes the friction between the friction block 12 and the friction disc 13, thereby changing the resistance of the tension roller 4 and thus adjusting the winding tightness. The slide cylinder 19 is moved, exposing the fixing groove 16. The snap-fit ​​connector 24 engages with the snap-fit ​​hole 21 under the action of the third spring 25, fixing the slide cylinder 19. Then, the take-up roller 17 is removed from the fixing groove 16, and the two ends of the new take-up roller 17 are placed into the fixing groove 16. The pressing head 31 is pressed, causing the pressing rod 23 to move the push plate 22. The push plate 22 moves and pushes the snap-fit ​​connector 24 to move, disengaging the snap-fit ​​connector 24 from the snap-fit ​​hole 21. The slide cylinder 19 returns to its original position under the action of the second spring 20, covering the fixing groove 16 and fixing the two ends of the take-up roller 17 in the fixing groove 16, completing the replacement and facilitating the replacement process.
