[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-4 A plastic film winding device includes a base 1, a positioning component 2 installed on the top of the base 1 near the front end, and a pick-and-place component 3 installed at the rear of the base 1.

[0025] See Figure 2 Furthermore, the positioning component 2 includes two support seats 4, which are fixedly installed on the top of the base 1 on both sides. A lifting groove 5 is provided inside the support seat 4 near the top. A lifting shaft block 6 is movably installed inside the lifting groove 5. Two sliding rods 7 are installed inside the lifting groove 5 and through the lifting shaft block 6. A first spring 8 is sleeved on the outside of the sliding rod 7. A rotating roller 9 is movably installed between the two lifting shaft blocks 6 near the bottom. An adjusting rod 10 is movably installed between the two lifting shaft blocks 6 near the top. Two positioning plates 11 are connected to the outside of the adjusting rod 10. A rocker plate 12 is installed at both ends of the adjusting rod 10.

[0026] The lifting shaft block 6 is sleeved on the outside of the two slide rods 7 and is arranged to slide up and down. The two slide rods 7 pass through the inside of the lifting shaft block 6, near the front and rear ends respectively. The lifting shaft block 6 is guided to slide by the slide rods 7.

[0027] The rotating roller 9 is located between two lifting shaft blocks 6 and connected by bearings. Two positioning plates 11 are sleeved on the outside of the rotating roller 9 and the adjusting rod 10. The two positioning plates 11 are used for positioning on both sides of the plastic film.

[0028] The threads on both ends of the outer periphery of the adjusting rod 10 are in opposite directions. The positioning plate 11 and the adjusting rod 10 are connected by threads. The positioning plate 11 is adjusted by the adjusting rod 10 to accommodate films of different widths.

[0029] Specifically, the plastic film passes over the rotating roller 9, causing the lifting shaft block 6 to slide downward under the pulling action, and then slides upward under the action of the first spring 8. The rotating roller 9 tightens the plastic film, and the adjusting rod 10 drives the two positioning plates 11 to slide, thereby positioning plastic films of different widths.

[0030] Example 2

[0031] See Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the pick-and-place assembly 3 includes two housings 13 and a receiving box 14. The receiving box 14 is installed between the two housings 13. Inside the housing 13, a rotating shaft 15 is fixedly connected to the inner side of the output shaft of the motor. A telescopic rod 16 is movably installed through the inner side of the rotating shaft 15. A positioning plate 18 is fixedly installed at the front end of the telescopic rod 16. A second spring 17 is sleeved on the outside of the telescopic rod 16. A card seat 19 is fixedly installed on the inner side of the positioning plate 18. A card slot 20 is opened on the top of the card seat 19. A chuck 21 is fixedly installed inside the card slot 20.

[0032] The telescopic rod 16 has a hexagonal cross-section, and a hanging plate is provided at the outer end of the telescopic rod 16 and inside the rotating shaft 15. The hanging plate is used to hold the telescopic rod 16 when it is extended.

[0033] The side view of the card slot 20 is U-shaped, and the two card holders 19 are symmetrically arranged. The space between the two card slots 20 is used to place the take-up drum.

[0034] Specifically, the motor inside the housing 13 drives the rotating shaft 15 to rotate, and the telescopic rod 16, under the action of the second spring 17, drives the positioning plate 18 and the card seat 19 to slide inward. The two card seats 19 press and fix the take-up drum to roll up the plastic film. After the winding is completed, the card slot 20 rotates to the bottom and pushes the card seats 19 to both sides so that the take-up drum automatically falls into the collection box 14 for collection.

[0035] In actual operation, the plastic film is wrapped around the rotating roller 9, and the take-up drum is placed between the two card holders 19. The plastic film is wound around the take-up drum to achieve winding.

[0036] During the winding process, the plastic film is pulled downward by the roller 9 to adapt to the downward movement. The lifting shaft block 6 provides an upward sliding force under the action of the first spring 8, thereby continuously tightening the plastic film to prevent wrinkles from occurring during the winding process. When positioning, one of the rocker discs 12 is shaken to make the adjusting rod 10 drive the two positioning plates 11 to slide, thereby changing the distance between the two positioning plates 11 and positioning and correcting the two sides of the plastic film of different widths.

[0037] When changing the take-up drum, the two card holders 19 rotate to rotate the card slots 20 downwards. By pushing the card holders 19 to both sides, the take-up drum automatically falls into the take-up box 14 through the card slots 20. The card slots 20 rotate upwards, and the new take-up drum is placed between the two card slots 20. The telescopic rod 16 automatically slides inwards under the action of the second spring 17 to press and fix the take-up drum. The rotating shaft 15 and the card holders 19 are rotated by the motor in the machine housing 13 to perform winding.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
