Description

Technical Field

[0001] This utility model relates to the field of stretch film winding technology, and in particular to a deviation correction device for stretch film winding. Background Technology

[0002] Stretch film is commonly used in the packaging of various products, especially in logistics, warehousing, and goods transportation. It effectively protects product surfaces from scratches and abrasions, while preventing damage from external factors such as dust and moisture. With its excellent stretchability, self-adhesion, and high transparency, it holds an important position in the packaging industry and is widely used in food, daily necessities, industrial products, and many other fields.

[0003] A search revealed a Chinese patent with publication number "CN222373962U" that discloses "a correction device for winding stretch film." This device uses a drive motor, gears, and two racks to move connecting blocks closer together, which in turn moves two sets of second rotating rollers. This adjusts the horizontal position of the stretch film, preventing unevenness on the film roll surface caused by film misalignment. This ensures the stretch film adheres tightly and evenly to the surface of the packaged object during packaging, improving the sealing and protective performance of the packaging. The tension of the stretch film can be adjusted using an electric push rod, slide rail, sliding block, and adjusting rod to control the tension during winding. Appropriate tension ensures smooth winding and effectively prevents problems such as film breakage, loosening, or loose packaging caused by excessive or insufficient tension.

[0004] However, the aforementioned patent cannot limit the two sides of the wound stretch film, which reduces the working efficiency of stretch film winding. Therefore, we propose a deviation correction device for stretch film winding to solve the above-mentioned problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Reference Figures 1-3 As shown, a guide device for winding stretch film includes a base plate 1. A set of support legs 2 is provided at each of the four corners of the lower end of the base plate 1. A mounting frame 3 is fixedly connected to one side of the upper end of the base plate 1. A winding roller 4 is installed on the inner side of the mounting frame 3. Four sets of first limiting rollers 5 are provided above the base plate 1. A positioning component is provided on one side of the four sets of first limiting rollers 5. The positioning component includes two sets of frame plates 6, which are respectively arranged on both sides of the four sets of first limiting rollers 5. A positioning roller 7 is provided on both sides of the four sets of first limiting rollers 5. A driving component is provided between the multiple sets of positioning rollers 7 and the frame plates 6.

[0024] The driving component includes two sets of first fixing blocks 8, which are respectively fixedly connected to the upper ends of two sets of frame plates 6. A bidirectional screw 9 is rotatably connected to the end face of the two sets of first fixing blocks 8. One end of the bidirectional screw 9 is connected to the output end of the rotating motor 10. The rotating motor 10 is mounted on the end face of one set of first fixing blocks 8. Two sets of threaded sleeves 11 are threaded on the outer side of the bidirectional screw 9. Two sets of connecting rods 12 are fixedly connected to the outer wall of each set of threaded sleeves 11. A set of sliding sleeves 13 is fixedly connected to the other end of each set of connecting rods 12. A set of connecting plates 14 is fixedly connected to the lower end of each set of sliding sleeves 13. Two sets of connecting rods 15 are fixedly connected to the lower end face of each set of connecting plates 14. The lower ends of each set of connecting rods 15 are respectively fixedly connected to the upper ends of multiple sets of positioning rollers 7. The internal sliding sleeves 13 are connected to two sets of sliding rods 16. Both ends of the two sets of sliding rods 16 are fixedly connected to a set of second fixing blocks 17. The lower ends of the multiple sets of second fixing blocks 17 are fixedly connected to the upper ends of the two sets of frame plates 6.

[0025] In this embodiment, the stretch film is sequentially passed through two sets of second limiting rollers 28 and multiple sets of first limiting rollers 5, and then wound onto the winding roller 4. The motor at one end of the winding roller 4 is started, and the motor drives the winding roller 4 to wind the stretch film. Before winding, the rotary motor 10 is started, and the rotary motor 10 drives the bidirectional screw 9 to rotate. The bidirectional screw 9 drives two sets of threaded sleeves 11 to move. The two sets of threaded sleeves 11 drive multiple sets of sliding sleeves 13 to move via connecting rod 12. The multiple sets of sliding sleeves 13 drive multiple sets of positioning rollers 7 via connecting plate 14 and connecting rod 15. The movement of the rollers allows multiple sets of positioning rollers 7 to position both sides of the stretch film, preventing the film from shifting during winding and improving the winding efficiency. The positioning assembly, consisting of the frame plate 6, positioning rollers 7, and driving components, allows for adjustment of the positions of the multiple sets of positioning rollers 7, enabling the limiting of stretch films of different widths. This improves the applicability of the correction device, effectively enhancing winding accuracy and efficiency, and preventing the problem of insufficient limiting of both sides of the wound stretch film, which reduces the winding efficiency.

[0026] Furthermore, two sets of mounting blocks 18 are fixedly connected to the side walls of both sets of frame plates 6. Two sets of mounting rods 19 are fixedly connected to the end faces of the multiple sets of mounting blocks 18. A set of fixing sleeves 20 is fixedly sleeved on the outer side of each of the two sets of mounting rods 19. A set of horizontal plates 21 is fixedly connected to the side walls of each of the two sets of fixing sleeves 20. Two sets of vertical plates 22 are fixedly connected to one side wall of each of the two sets of horizontal plates 21. The multiple sets of vertical plates 22 are respectively connected to the two ends of the multiple sets of first limiting rollers 5. By setting the mounting blocks 18, mounting rods 19, fixing sleeves 20, horizontal plates 21 and vertical plates 22, the multiple sets of first limiting rollers 5 can be supported.

[0027] Furthermore, two sets of support plates 27 are fixedly connected to one side of the upper end of the base plate 1, and two sets of second limiting rollers 28 are rotatably connected to the side walls of the two sets of support plates 27; by setting the support plates 27, the second limiting rollers 28 can be supported, and by setting the second limiting rollers 28, the stretching film can be auxiliaryly limited.

[0028] Example 2

A set of limiting rods 24 are slidably connected to both ends of the two sets of lifting plates 23. Two sets of auxiliary plates 25 are fixedly connected to the lower ends of the multiple sets of limiting rods 24, and the lower ends of the two sets of auxiliary plates 25 are fixedly connected to the upper ends of the base plate 1. A hydraulic rod 26 is fixedly connected to the upper end of one set of auxiliary plates 25, and the upper end of the hydraulic rod 26 is fixedly connected to the lower end of the lifting plate 23. When the hydraulic rod 26 is activated, it drives one set of lifting plates 23 to move upwards. The lifting plates 23 then drive multiple sets of first limiting rollers 5 to move upwards, allowing adjustment of the height of the first limiting rollers 5. This facilitates adjustment of the tension of the wound stretch film, further improving the working efficiency of the stretch film winding process.
