Description

A high-speed packaging film anti-deviation correction mechanism Technical Field

[0001] This utility model relates to the field of packaging film processing technology, and in particular to a high-speed packaging film anti-deviation and correction mechanism. Background Technology

[0002] Packaging film is a flexible thin film material used to wrap, protect or seal items. It is lightweight, highly malleable and low in cost, and is widely used in food, medicine, industrial products and other fields. During the processing, packaging film is rolled up and packaged by winding equipment.

[0003] Existing winding equipment typically applies tension to the packaging film using two pressure rollers to facilitate winding the film by the take-up roller. During operation, the pressure rollers may sink, causing an imbalance in the tension of the packaging film and resulting in deviation during winding, which affects the processing efficiency of the packaging film.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5. This utility model provides a technical solution:

[0023] A high-speed packaging film anti-deviation and correction mechanism includes a base 1. A take-up roller 2 and a drive motor 12 are mounted at one end of the base 1, and a guide roller 3 is mounted at the other end. A first support plate 4 and a second support plate 5 are positioned between the take-up roller 2 and the guide roller 3. The height of the first support plate 4 is greater than the height of the second support plate 5. A first groove 10 is formed on the top of the first support plate 4, and a first slide block 13 is slidably connected within the first groove 10. A first spring 19 is positioned between the first slide block 13 and the bottom of the first groove 10. A second groove 11 is formed on the top of the second support plate 5, and a second slide block 23 is slidably connected to the second groove 11. The second slide block 23 is slidably connected to... A second spring 28 is provided between the bottom of the second slide 11. The first slide 13 is rotatably connected to the first pressure roller 6 via the first rotating shaft 8. The second slide 23 is rotatably connected to the second pressure roller 7 via the second rotating shaft 9. A correction part is provided between the first support plate 4 and the second support plate 5 to prevent the packaging film from shifting during the winding process. There is a height difference between the first support plate 4 and the second support plate 5, which can apply moving pressure to the packaging film and prevent the packaging film from shifting due to insufficient tension. The presence of the first spring 19 and the second spring 28 ensures that the tension on the packaging film is within a safe range, which can prevent the packaging film from breaking due to excessive pressure.

[0024] Specifically, as shown in Figures 2, 3, and 5, the correction section includes a first adjusting plate 15 and a second adjusting plate 21. A third rotating shaft 16 is rotatably connected to the first adjusting plate 15. A first gear 17 is provided at one end of the third rotating shaft 16. A first toothed plate 14 is provided on the side of the first slide 13, and the first toothed plate 14 and the first gear 17 are meshed together. A fourth rotating shaft 24 is rotatably connected to the second adjusting plate 21. A second gear 26 is provided at one end of the fourth rotating shaft 24. A second toothed plate 25 is provided on the side of the second slide 23, and the second gear 26 and the second toothed plate 25 are meshed together. A first roller 18 is provided at one end of the third rotating shaft 16, and a second roller 27 is provided at one end of the fourth rotating shaft 24. The first roller 18 and the second roller 27 are connected by a transmission belt. 20. Transmission connection: When the first pressure roller 6 sinks, the first slide 13 drives the first toothed plate 14 to slide downwards. The first toothed plate 14 drives the first gear 17 to rotate. The first gear 17 drives the first roller 18 to rotate through the third rotating shaft 16. The first roller 18 drives the second roller 27 to rotate through the transmission belt 20. The second roller 27 drives the second gear 26 to rotate through the fourth rotating shaft 24. The second gear 26 drives the second toothed plate 25 to move downwards. The second toothed plate 25 drives the second slide 23 to move downwards. The second slide 23 drives the second pressure roller 7 to move downwards. In this way, the tension applied to the packaging film by the first pressure roller 6 and the second pressure roller 7 is balanced, which will not cause the tension on the packaging film to decrease, thus preventing the packaging film from shifting during the winding process.

[0025] Specifically, as shown in Figures 2 and 5, a third adjusting plate 22 is provided between the first adjusting plate 15 and the second adjusting plate 21. A positioning plate 36 is provided between the third adjusting plate 22 and the base 1. An adjusting mechanism is provided between the third adjusting plate 22 and the second adjusting plate 21 to adjust the distance between the first adjusting plate 15 and the second adjusting plate 21. The setting of the adjusting mechanism can improve the applicability of the correction part. The adjusting mechanism includes a first threaded rod 30 and a first limiting rod 29. The first threaded rod 30 and the third adjusting plate 22 are rotatably connected. The first threaded rod 30 and the second adjusting plate 21 are threadedly connected. The first limiting rod 29 and the third adjusting plate 22 are fixedly connected. The first limiting rod 29 and the third adjusting plate 22 are slidably connected. A knob 31 is provided on the first threaded rod 30. By rotating the knob 31, the first threaded rod 30 can be rotated, thereby controlling the distance between the first adjusting plate 15 and the second adjusting plate 21.

[0026] Specifically, as shown in Figure 2, a third slide block 32 is provided above the third adjusting plate 22. A third roller 33 adapted to the transmission belt 20 is rotatably connected to the third slide block 32. A second limiting rod 37 is provided on the third adjusting plate 22. A limiting plate 34 is provided at the top of the second limiting rod 37. The second limiting rod 37 and the third slide block 32 are slidably connected. A third spring 35 is provided between the limiting plate 34 and the third slide block 32. The combination of the third roller 33 and the third spring 35 can ensure that the tension variation range of the transmission belt 20 is within a controllable range, preventing the tension from decreasing and reducing the friction between the transmission belt 20 and the first roller 18 and the second roller 27.

[0027] In summary, the high-speed packaging film anti-deviation correction mechanism provided in this embodiment achieves the following: when the first pressure roller 6 sinks, the first slide block 13 drives the first toothed plate 14 to slide downwards, the first toothed plate 14 drives the first gear 17 to rotate, the first gear 17 drives the first roller 18 to rotate via the third rotating shaft 16, the first roller 18 drives the second roller 27 to rotate via the transmission belt 20, the second roller 27 drives the second gear 26 to rotate via the fourth rotating shaft 24, the second gear 26 drives the second toothed plate 25 to move downwards, the second toothed plate 25 drives the second slide block 23 to move downwards, and the second slide block 23 drives the second pressure roller 7 to move downwards. In this way, the tension applied to the packaging film by the first pressure roller 6 and the second pressure roller 7 is balanced, preventing the tension on the packaging film from decreasing and causing the packaging film to deviate during the winding process.
