Description

Technical Field

[0001] This utility model relates to the field of packaging film winding technology, specifically to a polyvinyl chloride packaging film winding device. Background Technology

[0002] Plastic packaging film is a thin film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It is used for packaging and as a coating layer. Plastic packaging and plastic packaging products have an increasingly large market share and are widely used in food, medicine, chemical and other fields. Among them, food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, retortable food packaging, fast food packaging, etc. These products have brought great convenience to people's lives.

[0003] Currently, existing plastic packaging films need to be wound and collected after production. However, plastic packaging films come in various sizes. If a uniform winding device is used, misalignment may occur during the winding process. Using different sizes of winding devices separately is also very costly. Therefore, there is an urgent need to design a polyvinyl chloride packaging film winding device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a polyvinyl chloride packaging film winding device to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A polyvinyl chloride (PVC) packaging film winding device includes a processing table. A conveying mechanism and a fixing frame are mounted on the top of the processing table. The fixing frame is U-shaped, with a fixing plate installed on the bottom of its inner wall. A rotating plate is rotatably fitted to one end of the fixing plate. A first motor is mounted on one side of the rotating plate, and a winding rod is fixedly connected to the output end of the first motor. A moving plate is slidably fitted inside the fixing frame. A telescopic cylinder is installed between the top of the fixing frame and one side of the moving plate. A limiting groove corresponding to the winding rod is opened at the bottom end of the moving plate. A support rod is mounted on one side of the rotating plate, with a connecting rod rotatably fitted to one end of the support rod. One end of the connecting rod is slidably fitted to one side of the inner wall of the fixing frame. A through groove is opened on one side of the moving plate, slidably fitted with the support rod and the connecting rod. A collection port corresponding to the fixing frame is opened on the top of the processing table, and an inclined slide corresponding to the collection port is installed on the processing table.

[0007] Furthermore, a fixing rod is installed on one side of the inner wall of the fixing frame, and one end of the connecting rod is slidably and rotatably fitted inside the fixing rod.

[0008] Furthermore, a round-headed rod corresponding to the limiting groove is slidably fitted inside the movable plate, and a spring is provided between one end of the round-headed rod and one side of the movable plate.

[0009] Furthermore, a locking block is provided at the top of the take-up bar for mounting an external take-up roller.

[0010] Furthermore, the conveying mechanism includes a mounting frame installed on the top of the processing table, two conveying rollers rotatably fitted within the mounting frame, and a second motor installed on one side of the mounting frame, the output end of the second motor being fixedly connected to one end of one of the conveying rollers.

[0011] Furthermore, a fixed box is installed on the top of the processing table, and a moving block is slidably fitted inside the fixed box. A cutting blade is installed on the top of the moving block.

[0012] In the above technical solution, the polyvinyl chloride packaging film winding device provided by this utility model has the following beneficial effects:

[0013] The movable plate, driven by a telescopic cylinder, moves along the winding rod via a limiting groove. This allows for the adjustment of the movable plate's position to limit the movement of different sized plastic packaging films, facilitating winding and reducing misalignment. A connecting rod allows the movable plate to slide after it moves out of the winding rod's range, enabling the rotating plate and support rod to rotate. This allows the wound plastic packaging film to be removed from the inclined slide. When the movable plate returns, the through groove supports the support rod and connecting rod, allowing the rotating plate to rotate and reset for winding, facilitating the removal of the wound plastic packaging film or the insertion of a new winding roller.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 As shown in the figure, this utility model provides a polyvinyl chloride packaging film winding device.

[0022] The system includes a processing table 1, a conveying mechanism 2 and a fixed frame 3 mounted on the top of the processing table 1. The fixed frame 3 is U-shaped, and a fixed plate 4 is installed on the bottom of the inner wall of the fixed frame 3. A rotating plate 5 is rotatably fitted at one end of the fixed plate 4. A first motor 6 is installed on one side of the rotating plate 5. A winding rod 7 is fixedly connected to the output end of the first motor 6. A moving plate 8 is slidably fitted inside the fixed frame 3. A telescopic cylinder 9 is installed between the top of the fixed frame 3 and one side of the moving plate 8. A limiting groove 10 corresponding to the winding rod 7 is opened at the bottom end of the moving plate 8. A support rod 11 is installed on one side of the rotating plate 5. A connecting rod 12 is rotatably fitted at one end of the support rod 11. One end of the connecting rod 12 is slidably fitted on one side of the inner wall of the fixed frame 3. A through groove 13 is opened on one side of the moving plate 8, which is slidably fitted with the support rod 11 and the connecting rod 12. A collection port 14 corresponding to the fixed frame 3 is opened on the top of the processing table 1. An inclined slide 15 corresponding to the collection port 14 is installed on the processing table 1.

[0023] Reference Figure 2-3 In this embodiment, a fixing rod 23 is installed on one side of the inner wall of the fixing frame 3, and one end of the connecting rod 12 is slidably and rotatably fitted within the fixing rod 23. The fixing rod 23 allows the connecting rod 12 to slide along it. When the through groove 13 does not support the connecting rod 12, the connecting rod 12 can rotate within the fixing rod 23, allowing the rotating plate 5 and the support rod 11 to rotate.

[0024] Reference Figure 4In this embodiment, a round-headed rod 24 corresponding to the limiting groove 10 is slidably fitted inside the movable plate 8. A spring 25 is provided between one end of the round-headed rod 24 and one side of the movable plate 8. Through the round-headed rod 24, after the winding rod 7 enters the limiting groove 10, the round-headed rod 24 can support the winding rod 7, so that the winding rod 7 can rotate and wind stably. When the winding rod 7 enters and exits the limiting groove 10, it will squeeze the round-headed rod 24 to elastically contract.

[0025] Reference Figure 2 In this embodiment, the top of the take-up bar 7 is provided with a locking block 22, which is used for mounting the external take-up roller. By using the locking block 22, the take-up roller used for winding can be fitted onto the periphery of the take-up bar 7, so that the locking block 22 fixes the take-up roller.

[0026] Reference Figure 1 The conveying mechanism 2 in this embodiment includes a mounting frame 16 mounted on the top of the processing table 1, two conveying rollers 17 rotatably fitted within the mounting frame 16, and a second motor 18 mounted on one side of the mounting frame 16. The output end of the second motor 18 is fixedly connected to one end of one of the conveying rollers 17. The second motor 18 can be activated to drive one of the conveying rollers 17 to rotate, causing the conveying roller 17 to rub against and move the plastic packaging film, thus conveying the plastic packaging film. Simultaneously, the plastic packaging film will rub against and move the other conveying roller 17 to rotate.

[0027] Reference Figure 1 In this embodiment, the top of the processing table 1 is equipped with a fixed box 19, and a movable block 20 is slidably fitted inside the fixed box 19. A cutting blade 21 is installed on the top of the movable block 20. The movable block 20 can be moved by the cutting blade 21, so that the movable block 20 drives the cutting blade 21 to move, allowing the cutting blade 21 to cut the plastic packaging film.

[0028] Working principle: In use, first install the take-up roller onto the periphery of the take-up rod 7, then adjust the telescopic cylinder 9 to move the moving plate 8. The movement of the moving plate 8 will move the through groove 13, allowing the through groove 13 to support the connecting rod 12. The connecting rod 12 will slide, and the sliding of the connecting rod 12 will drive the support rod 11 to rotate, keeping the support rod 11 and the connecting rod 12 horizontal. The rotation of the support rod 11 will drive the rotating plate 5 to rotate, causing the take-up rod 7 to rotate, allowing the take-up rod 7 to enter the limit. The plastic packaging film is placed in the slot 10, and the position of the moving plate 8 is continuously adjusted according to the size of the plastic packaging film. The plastic packaging film is conveyed by the conveying mechanism 2. The first motor 6 is started to drive the winding rod 7 to rotate, so that the winding rod 7 drives the winding roller to wind the plastic packaging film. After the plastic packaging film is wound, the moving plate 8 is moved out of the range of the winding rod 7. At this time, the connecting rod 12 will slide and move, so that the rotating plate 5 and the winding rod 7 can rotate. Then the wound plastic packaging film winding roller can be taken out through the collection port 14 and the inclined slide 15.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
