Description

Technical Field

[0001] This utility model relates to an ultra-thin plastic sheet winding device, belonging to the field of plastic sheet production technology. Background Technology

[0002] Plastic sheets refer to materials used in the production of disposable plastic cups, plates, bowls, dishes, boxes, and other thermoformed products. They are widely used in packaging for food, vegetables, fruits, beverages, dairy products, and industrial parts. Plastic sheets are made by heating plastic raw materials and calendering, extruding, or molding them into flat shapes. Depending on the raw materials and processing technology, plastic sheets can have a variety of different physical properties and are suitable for various industries and applications. After the plastic sheets are manufactured, they need to be wound into rolls using mechanical devices. After the sheets are wound into rolls, the rolled rolls need to be removed and replaced with new rolls.

[0003] According to Chinese Patent No. CN214779649U, a plastic sheet winding device includes a movable support, a fixed support, an air shaft, and a driving component. The movable support has multiple rotating wheels at its bottom and can move away from the fixed support. A locking assembly for fixing the movable support is provided between the movable support and the fixed support. The air shaft is located at the top of the movable support and is detachably connected to it. The air shaft and the movable support are rotatably connected. In the above patent solution, when removing the wound roll, it is necessary to control the winding frame to separate, making the roll disassembly and replacement inconvenient. Moreover, as the roll is wound, its weight increases, making it difficult for the winding device to support the roll, resulting in poor stability during winding. Therefore, we provide an ultra-thin plastic sheet winding device to solve the above problems. Utility Model Content

[0020] Please see Figure 1-4 In this utility model, an ultra-thin plastic sheet winding device includes a support platform 1, a support shell 14 fixedly connected to the bottom surface of the support platform 1, a fixing plate 11 fixedly connected to the upper surface of the support platform 1, a winding shaft 7 rotatably connected to the front of the fixing plate 11 via a bearing, two support springs 8 provided on the outer surface of the winding shaft 7, two second springs 9 fixedly connected to the inner wall of the winding shaft 7, and connecting blocks 24 fixedly connected to the ends of the two second springs 9 that are close to each other, and two openings opened on the outer surface of the winding shaft 7. 25. Both ends of the two support springs 8 pass through the openings 25 and are connected to the connecting block 24. The back of the fixing plate 11 is equipped with a drive motor 10. The output end of the drive motor 10 is connected to the take-up shaft 7. The take-up drum 6 is sleeved on the outside of the take-up shaft 7. The take-up drum 6 squeezes the support springs 8. The rebound action of the second spring 9, together with the connecting block 24, squeezes the support springs 8, so that the support springs 8 press against the take-up drum 6, which makes it convenient for the drive motor 10 to drive the take-up drum 6 to rotate and take up the ultra-thin plastic sheet.

[0021] Two support frames 13 are provided above the support platform 1. Each support frame 13 is rotatably connected to a support drum 12 through bearings. Two sets of sliding holes 18 are provided on the upper surface of the support platform 1. A sliding rod 19 is slidably connected inside each sliding hole 18. The top end of each sliding rod 19 is connected to the bottom surface of the support frame 13. The bottom end of each sliding rod 19 passes through the support platform 1 and extends into the interior of the support shell 14. A first spring 20 is sleeved on the outer surface of each sliding rod 19. As the winding diameter of the take-up drum 6 increases, the plastic sheet on the outside of the take-up drum 6 contacts the support drum 12. The support drum 12 rotates in coordination with the take-up drum 6 to wind up the drum, thereby ensuring the stability of the winding device.

[0022] The support shell 14 has a sliding plate 22 inside. The bottom end of each sliding rod 19 is connected to the upper surface of the sliding plate 22. The inner wall of the support shell 14 has two sets of sliding grooves 21. Each sliding groove 21 has a slider 23 slidably connected to its inner wall. The sides of the two sets of sliders 23 that are close to each other are connected to the sliding plate 22. The sliders 23 and the sliding grooves 21 cooperate with the sliding plate 22 to ensure the stability of the sliding plate 22. The sliding plate 22 is connected to the bottom end of the sliding rod 19, so that the two support frames 13 can be adjusted synchronously. The bottom surface of the support shell 14 is fixedly connected to a base 4. The upper surface of the base 4 has two sets of fixing holes 3. The left and right sides of the fixing plate 11 are fixed. Two reinforcing plates 17 are connected, and the bottom surface of each reinforcing plate 17 is connected to the upper surface of the support platform 1. The base 4 is provided with fixing holes 3 to facilitate the fixing of the winding device. The reinforcing plates 17 serve to reinforce the bottom connection of the fixing plate 11 and ensure the stability of the reinforcing plates 17. The front of the support shell 14 is fitted with a panel 15 by screws. Two handles 2 are fixedly connected to the front of the panel 15. A control switch 16 is installed on the front of the support shell 14 to facilitate the control of the winding device. Two limiting plates 5 are fixedly connected to the upper surface of the support platform 1. Multiple winding drums 6 are provided between the two limiting plates 5. The limiting plates 5 can hold the winding drums 6.

[0023] The working principle of this utility model is as follows:

[0024] In use, the winding device is first fixed in place by the base 4, the power supply of the winding device is turned on, and the winding drum 6 is placed on the outside of the winding shaft 7. The winding drum 6 presses against the support spring 8. The rebound action of the second spring 9, together with the connecting block 24, presses the support spring 8, so that the support spring 8 is pressed against the winding drum 6. This facilitates the drive motor 10 to drive the winding drum 6 to rotate and wind up the ultra-thin plastic sheet. During the winding process, as the winding diameter of the winding drum 6 increases, the plastic sheet on the outside of the winding drum 6 comes into contact with the support rotating drum 12. The support rotating drum 12 rotates in coordination with the winding drum 6 to wind up the sheet, thereby ensuring the stability of the winding device in the winding process.
