Description
Technical Field
[0001] This utility model relates to the field of take-up roller technology, and in particular to a POF heat shrink film take-up roller. Background Technology
[0002] In the production and subsequent processing of POF heat shrink film, the quality of the winding process directly affects the film's storage, transportation, and final use. As the core component for film winding, the positional accuracy of the side baffles on the winding roller is crucial for preventing film deviation, avoiding edge wear, and ensuring the neatness of the film roll.
[0003] Currently, most POF heat shrink film winding rollers on the market have fixed side baffles or require manual disassembly and replacement of baffles of different specifications to adapt to films of different widths. When processing POF heat shrink films of different widths, manually adjusting the side baffles is not only cumbersome and time-consuming, but also makes it difficult to ensure a precise match between the distance between the two side baffles and the film width. Adjustment errors can easily lead to problems such as film deviation and edge compression deformation during winding. Furthermore, mechanical jamming can easily occur during adjustment, resulting in uneven force on the side baffles, which in turn affects the tightness and neatness of film winding, and may even cause quality defects such as wrinkles and tears at the film edges, increasing production costs and scrap rates. Moreover, frequent manual intervention reduces production efficiency. Especially in automated production lines, this inconvenience in flexibly and quickly adjusting the position of the side baffles according to the film width seriously restricts the continuity and intelligence level of production. Therefore, this utility model proposes a POF heat shrink film winding roller to solve the above problems. Utility Model Content

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a POF heat shrink film take-up roller, including a take-up roller body 1. Support rods 2 are installed at both ends of the take-up roller body 1. An mounting plate 3 is installed at one end of the support rod 2. An mounting shaft 4 is installed at one end of the mounting plate 3. A fixing groove 5 is opened through the inside of the take-up roller body 1. Side baffles 6 are installed on both sides of the outer wall of the take-up roller body 1. A buffer mechanism is provided on the inner side of the side baffles 6. A silicone pad 7 is installed at one end of the buffer mechanism. The take-up roller body 1 has a hollow design. An adjustment mechanism is provided inside the take-up roller body 1.
[0020] The adjusting mechanism includes a mounting cavity 12, a rotating wheel 13, a threaded rod 14, a threaded sleeve 15, a connecting rod 16, and a limiting structure. The mounting cavity 12 is installed inside the take-up roller body 1. The rotating wheel 13 is installed at one end of the mounting cavity 12. The threaded rod 14 is installed inside the mounting cavity 12. One end of the rotating wheel 13 is connected to one end of the threaded rod 14. The threads at both ends of the threaded rod 14 are in opposite directions. A threaded sleeve 15 is provided on the outer wall of the threaded rod 14. The connecting rod 16 is installed at one end of the threaded sleeve 15. One end of the connecting rod 16 is connected to one end of the inner side of the side baffle 6. When it is necessary to adjust the position of the side baffle 6 and the silicone pad 7, the operator rotates the rotating wheel 13 to drive the threaded rod 14 to rotate. Therefore, under the limitation of the limiting groove 17 and the limiting block 18, the threaded rod 14 drives the threaded sleeve 15 to move, and then the connecting rod 16 drives the side baffle 6 to move, thereby adjusting the side baffle 6 and the silicone pad 7 to the appropriate position according to the film width. At this time, the winding roller can be used to wind up the POF heat shrink film.
[0021] The limiting structure includes a limiting groove 17 and a limiting block 18. The limiting groove 17 is located inside the lower part of the mounting cavity 12. The limiting block 18 is provided inside the limiting groove 17. The top end of the limiting block 18 is connected to the bottom end of the threaded sleeve 15. The cross-section of the limiting groove 17 is larger than the cross-section of the limiting block 18. The limiting groove 17 and the limiting block 18 form a sliding structure. In use, the mutual cooperation between the limiting groove 17 and the limiting block 18 can limit the movement of the threaded sleeve 15, making the threaded sleeve 15 more stable when moving.
[0022] The buffer mechanism includes a damper 8, a telescopic spring 9, and a guide structure. The damper 8 is installed at one end of the side baffle 6, and one end of the damper 8 is connected to one end of the silicone pad 7. The telescopic spring 9 is provided on the outer wall of the damper 8. When the membrane edge generates instantaneous pressure due to tension fluctuations, the membrane first avoids rigid contact and membrane edge wear due to the elastic deformation of the silicone pad 7. The remaining pressure pushes the telescopic spring 9 to compress, and the telescopic spring 9 drives the silicone pad 7 to extend and retract. The elastic potential energy of the telescopic spring 9 is converted and absorbed to relieve tension. This can buffer the instantaneous tension impact during winding, avoid membrane edge tearing and indentation, reduce rigid friction between the side plate and the membrane, protect the film surface, stably adhere to the membrane edge, suppress deviation, and improve the stability of winding quality.
[0023] The guiding structure includes a guide hole 10 and a guide rod 11. The guide hole 10 is opened through both ends of the side baffle 6. The guide rod 11 is installed through the inside of the guide hole 10. One end of the guide rod 11 is connected to one end of the silicone pad 7. The inner diameter of the guide hole 10 is larger than the outer diameter of the guide rod 11. The guide hole 10 and the guide rod 11 form a sliding structure. In use, the mutual cooperation between the guide hole 10 and the guide rod 11 can guide the silicone pad 7 when it moves, making the silicone pad 7 more stable when it moves.
[0024] Working principle: When the positions of the side baffle 6 and the silicone pad 7 need to be adjusted, the operator rotates the rotating wheel 13 to drive the threaded rod 14 to rotate. Therefore, under the limit of the limiting groove 17 and the limiting block 18, the threaded rod 14 drives the threaded sleeve 15 to move, and then the connecting rod 16 drives the side baffle 6 to move. Thus, the side baffle 6 and the silicone pad 7 are adjusted to the appropriate position according to the film width. At this time, the take-up roller can be used to take up the POF heat shrink film. When the film edge generates instantaneous pressure due to tension fluctuation, the film first avoids rigid contact and film edge wear through the elastic deformation of the silicone pad 7. The remaining pressure pushes the telescopic spring 9 to compress, and the telescopic spring 9 drives the silicone pad 7 to extend and retract. The elastic potential energy of the telescopic spring 9 is converted and absorbed to relieve the tension.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
