Description
Technical Field
[0001] This utility model relates to the field of polyvinyl chloride (PVC) film production technology, specifically a winding machine for PVC film production. Background Technology
[0002] Winding machines are used in many industries. A winding machine is a mechanical device that rolls products into rolls. A winding machine generally consists of a core device called a winding drum and auxiliary winding devices such as winding rollers. The winding machine is driven by electricity, fluid, etc. In the production process of polyvinyl chloride film, a winding mechanism is needed to wind up the produced polyvinyl chloride film.
[0003] According to the description of a PVC film winding machine published on the patent website (authorization announcement number: CN220617712U), "This utility model relates to the field of winding machine technology, specifically a PVC film winding machine, including a base. Fixing frames are provided on both sides of the base surface. A fixing block is fixedly provided on one side of the fixing frame. An mounting block is fixedly connected to the top surface of the fixing block. A first bearing is movably connected to one side of the fixing block. A second bearing is movably connected to one side of the first bearing. A second drive shaft is fixedly connected to one side of the bottom end of the second bearing. A first drive shaft is fixedly connected to the other side of the second drive shaft. A slider is fixedly provided at the top of the fixing block. This utility model achieves synchronous material winding of the two drive shafts by providing a mounting block fixedly on one side of the fixing block, with a motor movably installed inside the mounting block. The motor drives the first drive shaft to rotate, and the second drive shaft is connected to the first drive shaft via a chain, thus driving the second drive shaft to rotate."
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] In use, this utility model uses a motor inside the mounting block to drive the first drive shaft to rotate, while the second drive shaft is connected to the first drive shaft by a chain, thus driving the second drive shaft to rotate. This achieves the synchronous winding of the two drive shafts. However, the film is generally wound and stored using a hollow paper winding drum. This device winds the film using a drive shaft, and after winding, the rolled PVC film needs to be removed from the drive shaft. Since the drive shaft is connected to the entire device, removing the drive shaft and the wound PVC film roll requires disassembling the entire device, which is very inconvenient. Therefore, it is necessary to improve the PVC film production winding machine to solve the above problems. Utility Model Content

A fixed seat 222 is fixedly mounted on the inner side of the connecting ring 221, and a micro motor 223 is fixedly mounted on the outer side of the fixed seat 222. A rotating shaft 224 is fixedly mounted on the output end of the micro motor 223, and a rotating disk 225 is fixedly mounted on the outside of the rotating shaft 224. A curved connecting rod 226 is rotatably mounted inside the rotating disk 225, and a fixed block 227 is slidably mounted inside the fixed seat 222. The input end of the micro motor 223 is electrically connected to an external power source.
[0029] Furthermore, it also includes a drive motor 4 and a belt 5. The drive motor 4 is fixedly installed on the top of the base 1. The belt 5 is driven between the pulley at the output end of the drive motor 4 and the pulley outside the connecting ring 221. The input end of the drive motor 4 is electrically connected to an external power source. The belt 5 causes the drive motor 4 to drive the connecting ring 221 to rotate.
[0030] Furthermore, the distance adjustment component 21 also includes a micro motor 211, which is fixedly installed on the side wall of the base 1. The output end of the micro motor 211 is fixed to one end of the threaded rod 212 inside the base 1. A slide rod 213 is fixedly installed inside the base 1. A first movable support arm 214 is slidably installed outside the slide rod 213. The input end of the micro motor 211 is electrically connected to an external power source, and the threaded rod 212 is driven to rotate by the micro motor 211.
[0031] Furthermore, there are two slide rods 213, which are evenly arranged on the left and right sides of the threaded rod 212. The fixed adjustment assembly 22 is provided in two sets, which are located inside the first movable support arm 214 and the first fixed support arm 215, respectively. By rotating the threaded rod 212, the first movable support arm 214 moves inward.
[0032] Furthermore, the end of the curved connecting rod 226 away from the rotating disk 225 is rotatably mounted on the outside of the fixed block 227, and the fixed block 227 is moved by the curved connecting rod 226.
[0033] Furthermore, it also includes an auxiliary winding mechanism 3, which includes a second fixed support arm 31 and a second movable support arm 32. The second fixed support arm 31 is fixedly installed on the top of the base 1, and the second movable support arm 32 is slidably installed inside the base 1. A telescopic pressure rod 33 is rotatably installed inside the second fixed support arm 31. A fixed connecting rod 34 is fixedly installed between the second movable support arm 32 and the first movable support arm 214. A support seat 35 is fixedly installed on the top of the base 1. A connecting column 36 is slidably installed inside the support seat 35. A pressure plate 37 is fixedly installed on the top of the connecting column 36. A spring 38 is fixedly installed on the bottom of the pressure plate 37. A roller 39 is provided inside the pressure plate 37 to press the wound polyvinyl chloride film.

[0035] In actual operation, when this device is used, the hollow part of the take-up drum is fitted onto the outside of the fixed seat 222. The threaded rod 212 is rotated by the micro motor 211, causing the first movable support arm 214 to move inward. This causes the fixed seat 222 in the fixing adjustment assembly 22 on the side of the first movable support arm 214 to also fit onto the hollow part in the middle of the take-up drum. The rotating shaft 224 is driven to rotate by the micro motor 223, which in turn drives the rotating disk 225 to rotate. Connected by the curved connecting rod 226, the fixed blocks 227 move outward, and all four fixed blocks 227 simultaneously push out, pressing against the inside of the take-up drum to fix it. This device can fix take-up drums of different sizes. The drive motor... Machine 4 drives the connecting ring 221 to rotate via belt 5, causing the take-up drum fixed outside the fixed base 222 to rotate, thereby achieving the winding effect. When the first movable support arm 214 moves inward, the second movable support arm 32 moves inward synchronously via the fixed connecting rod 34, adjusting the distance between the second fixed support arm 31 and the second movable support arm 32. Pressure is applied between the telescopic pressure rod 33 and the PVC film wound on the take-up drum, making the PVC film wound on the surface of the take-up drum taut. Then, the spring 38 makes the pressure plate 37 press tightly against the surface of the wound PVC film, and the roller 39 presses it down, making the PVC film wound more tightly and ensuring the quality of winding.
