Description

Technical Field

[0001] This utility model relates to the field of self-adhesive paper winding technology, specifically to a self-adhesive paper winding device. Background Technology

[0002] Self-adhesive paper is a composite material with adhesive pre-coated on the back of paper, film, or other materials and protected by a backing paper (release paper). When using it, simply peel off the backing paper to stick the face material to various surfaces.

[0003] The final step in each processing step involves winding up the long strips of self-adhesive paper or semi-finished self-adhesive paper. During winding, the self-adhesive paper is typically wrapped around a winding roller. As the winding length increases, the number of turns of self-adhesive paper wrapped around the winding roller increases, and the diameter also increases. This requires a certain distance from the roller closest to the winding roller to accommodate the diameter changes during winding. However, this results in different distances of the self-adhesive paper in the air at the beginning and end of winding. Especially when the distance is long, the self-adhesive paper suspended in the air is prone to vibration due to tension changes, airflow interference, and machine vibration, leading to unstable self-adhesive paper conditions. This can result in uneven winding edges or wrinkles during winding.

[0004] Therefore, a self-adhesive paper winding device is needed to solve the problem of wrinkles easily occurring during winding. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a self-adhesive paper winding device. By identifying the winding diameter, a dual-axis motor drives the first connecting block and the transition roller to move back and forth, thereby providing support in the thickness direction at different positions before the self-adhesive paper is wound (to adapt to changes in the winding diameter), while ensuring the stability of the self-adhesive paper.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a self-adhesive paper winding device, comprising: The support plate consists of two plates that stand opposite each other. A take-up roller, a transition roller, and an intermediate roller are rotatably connected between the support plates, arranged from back to front. A servo motor that is powered by the take-up roller is fixedly connected to the support plate. A laser detector is disposed between two support plates and is used to detect the outermost position of the take-up roller during winding. The linkage assembly includes a first connecting block and a second connecting block disposed between two support plates and slidably connected to their side walls. The first and second connecting blocks are located between the take-up roller and the intermediate roller and move back and forth. A first sliding block and a second sliding block are respectively fixedly connected to the lower parts of the first and second connecting blocks. The transition roller is rotatably connected between the two first sliding blocks. A laser detector is fixedly connected to one end of the two second sliding blocks that are close to each other. A dual-axis motor is fixedly connected to the first connecting block. The output shafts at both ends of the dual-axis motor pass through the two support plates and are slidably connected to the support plates. A first gear and a second gear are fixedly connected to the output shafts. A first rack that meshes with the first gear is fixedly connected to one side of the support plates that are far apart from each other. The second connecting block passes through the two support plates and is slidably connected to them. A second rack that is slidably connected to the outer plate is fixedly connected to one side of the second connecting block that is far apart from each other. The second rack meshes with the second gear.

[0007] The present invention is further configured such that: the support plate includes an outer plate and an inner plate, the two inner plates are detachably connected to the side walls of the two outer plates that are close to each other, the outer plates have an inwardly recessed receiving groove that is slidably connected to a first sliding block at one end that is close to each other, the inner wall of the receiving groove has a limiting groove, the first sliding block has a protrusion that is slidably connected to the limiting groove, the inner plate has an upper sliding groove and a lower sliding groove extending in the front-back direction through it from left to right, the upper sliding groove is slidably connected to a first connecting block, the inner wall of the receiving groove has a first through groove and a second through groove that are slidably connected to a second connecting block and extend front-back, the second connecting block passes through the upper sliding groove and the second through groove continuously, the output shaft of the dual-axis motor passes through the first through groove, and the inner plate also has a lower sliding groove through which the rotating shaft of the transition roller passes.

[0008] The present invention is further configured such that: a support block is detachably connected to one end of the two outer plates that are far apart from each other; the upper end of the support block facing the outer plate is provided with two stepped surfaces; a guide rail is fixedly connected to the stepped surface above the support block; the second rack is slidably connected to the guide rail; and the first rack is fixedly connected to the stepped surface below the support block.

[0009] The present invention is further configured such that the forward and backward movement trajectory line of the transition roller intersects with the line connecting the take-up roller and the intermediate roller.

[0010] The present invention is further configured such that the output shafts at both ends of the dual-axis motor pass through the first connecting block and are rotatably connected to the first connecting block.

[0011] The present invention is further configured such that the laser detector is positioned horizontally between the second connecting block and the take-up roller.

[0012] In summary, this utility model has the following beneficial effects: The transition roller is used as the last roller on the self-adhesive paper's film feeding path, closest to the take-up roller. It is driven to move away from or closer to the take-up roller. That is, at the beginning of winding, the transition roller is in the position closest to the take-up roller. As the length and diameter of the self-adhesive paper increases, a laser detector is used to detect the change in the diameter of the self-adhesive paper on the take-up roller, and then the signal is transmitted to a dual-axis motor. The dual-axis motor drives the transition roller away from the take-up roller and always maintains its fixed distance, further increasing the stability of the self-adhesive paper and preventing wrinkles from occurring during winding.

[0015] The present invention will now be described in detail with reference to the accompanying drawings of the embodiments thereof.

[0016] Example: This is a self-adhesive paper winding device, such as Figures 1 to 3As shown, the assembly includes a support plate and a linkage component for a laser detector 31. Two support plates are positioned opposite each other, with a take-up roller 33, a transition roller 28, and an intermediate roller 34 rotatably connected between them from back to front. A servo motor 35, which is powered by the take-up roller 33, is fixedly connected to the support plates. The laser detector 31 is positioned between the two support plates and is used to detect the outermost position of the take-up roller 33 during take-up. The linkage component includes a first connecting block 22 and a second connecting block 29 positioned between the two support plates and slidably connected to their sidewalls. The first connecting block 22 and the second connecting block 29 are located between the take-up roller 33 and the intermediate roller 34 and move back and forth. A first sliding block 2 is fixedly connected to the lower portion of each of the first connecting block 22 and the second connecting block 29. 7. The second sliding block 30 and the transition roller 28 are rotatably connected between the two first sliding blocks 27. The laser detector 31 is fixedly connected to one end of the two second sliding blocks 30 that is close to each other. The dual-axis motor 26 is fixedly connected to the first connecting block 22. The output shafts of the left and right ends of the dual-axis motor 26 pass through the two support plates and are slidably connected to the support plates. The first gear 24 and the second gear 25 are fixedly connected to the output shafts. The first rack 19 that meshes with the first gear 24 is fixedly connected to one side of the support plates that is far apart from each other. The second connecting block 29 passes through the two support plates and is slidably connected to them. The second rack 32 that is slidably connected to the outer plate 11 is fixedly connected to one side of the second connecting block 29 that is far apart from each other. The second rack 32 meshes with the second gear 25.

[0017] By adopting the above technical solution, when the self-adhesive paper is wound on the take-up roller 33, two laser detectors 31 are used to detect whether there is self-adhesive paper between them. When the diameter of the self-adhesive paper on the take-up roller 33 increases, it blocks the two laser detectors 31. At this time, the laser detectors 31 transmit signals to the dual-axis motor 26, and the dual-axis motor 26 drives the output shaft to rotate. The output shaft meshes with the first rack 19. Because the first rack 19 is fixedly connected to the support block 17, the output shaft rolls on the first rack 19, which can drive the first connecting block 22, the dual-axis motor 26, and the first... The sliding block 27 and the transition roller 28 move along the length of the first rack 19. Since the diameter of the first gear 24 is larger than the diameter of the second gear 25, it also drives the second gear 25, the second rack 32, the second connecting block 29, the second sliding block 30, and the laser detector 31 to move in the same direction. Because the second gear 25 and the second rack 32 are also meshed, the second connecting block 29 and the first connecting block 22 also move relative to each other. Specifically, when the first connecting block 22 moves away from the take-up roller 33, the second connecting block 29 also moves away from the first connecting block 22, and the first connecting block 29 moves away from the take-up roller 33. The second connecting block 29 also moves away from the take-up roller 33, so that when a large amount of self-adhesive paper is wound on the take-up roller 33, the first connecting block 22 is positioned further away from the take-up roller 33. When the diameter of the self-adhesive paper on the take-up roller 33 is large, the length of the self-adhesive paper suspended between the take-up roller 33 and the transition roller 28 is increased. When the rotational speed control precision of the take-up roller 33 is not high, the elasticity of the self-adhesive paper itself is used to increase the deformation length, thereby reducing tension. At the same time, it can also reduce the bending angle of the self-adhesive paper as it passes over the surface of the transition roller 28, preventing tension from concentrating at the transition roller 28. This increases the tension control effect of the entire self-adhesive paper. When less self-adhesive paper is wound on the take-up roller 33, the first connecting block 22 is closer to the take-up roller 33. At this time, when the rotation accuracy of the take-up roller 33 is not high, the diameter of the self-adhesive paper on the take-up roller 33 is small. The transition roller 28 is close to the self-adhesive paper wound on the take-up roller 33 to reduce the length of the self-adhesive paper suspended between the transition roller 28 and the take-up roller 33. This allows the self-adhesive paper to be wound well on the take-up roller 33 in the early stage and also increases the flatness of the self-adhesive paper wound on the take-up roller 33.

[0018] In some embodiments, such as Figures 4 to 5As shown, the support plate includes an outer plate 11 and an inner plate 12. The two inner plates 12 are detachably connected to the side walls of the two outer plates 11 that are close to each other. The outer plates 11 have an inwardly recessed receiving groove 13 that is slidably connected to the first sliding block 27 at one end that is close to each other. The inner wall of the receiving groove 13 has a limiting groove 14. The first sliding block 27 has a protrusion that is slidably connected to the limiting groove 14. The inner plate 12 has an upper sliding groove 15 and a lower sliding groove 16 that extend in the front-back direction and are slidably connected to the first connecting block 22. The inner wall of the receiving groove 13 has a first through groove 20 and a second through groove 21 that are slidably connected to the second connecting block 29 and extend in the front-back direction. The second connecting block 29 passes through the upper sliding groove 15 and the second through groove 21. The output shaft of the dual-axis motor 26 passes through the first through groove 20. The inner plate 12 also has a lower sliding groove 16 through which the rotating shaft of the transition roller 28 passes.

[0019] By adopting the above technical solution, and utilizing the detachable connection structure of the outer plate 11 and the inner plate 12, the first sliding block 27 and the second sliding block 30 are first inserted into the receiving groove 13, then the inner plate 12 is covered while maintaining the connection between the outer plate 11 and the inner plate 12. Then, the first connecting block 22 and the transition roller 28 are inserted from the groove on the outer plate 11 and installed with the first sliding block 27 (the installation method is a detachable connection). The structure of the receiving groove 13 supports the first sliding block 27 and the second sliding block 30. The detachable connection structure facilitates the installation of the entire equipment and also makes it convenient to replace and repair individual parts when they are damaged.

[0020] In some embodiments, such as Figures 4 to 5 As shown, a support block 17 is detachably connected to one end of the two outer plates 11 that are far apart from each other. The upper end of the support block 17 facing the outer plate 11 is set with two stepped surfaces. A guide rail 18 is fixedly connected to the stepped surface above the support block 17. The second rack 32 is slidably connected to the guide rail 18. The first rack 19 is fixedly connected to the stepped surface below the support block 17.

[0021] By adopting the above technical solution, the support block 17 and the side wall of the outer plate 11 are detachably connected by screws. That is, a threaded hole is machined on the outer plate 11, and a through hole is machined on the support block 17. Then, a screw is used to pass through the support block 17 and connect to the threaded hole, thereby completing the connection between the support block 17 and the outer plate 11. The support block 17 and the first rack 19 on it can be replaced, and the moving speed ratio of the first connecting block 22 and the second connecting block 29 can be adjusted according to different situations.

[0022] In some embodiments, such as Figures 4 to 5 As shown, the forward and backward movement trajectory lines of the transition roller 28 intersect with the line connecting the take-up roller 33 and the intermediate roller 34.

[0023] By adopting the above technical solution, the angle at which the moving trajectory line of the transition roller 28 intersects the line connecting the take-up roller 33 and the intermediate roller 34 can be adjusted according to the characteristics of different films during processing. This ensures that when the transition roller 28 is closest to the take-up roller 33, the self-adhesive paper can be well wound on the take-up roller 33, and wrinkles will not occur due to excessive contact pressure between the side wall of the self-adhesive paper and the surface of the transition roller 28 caused by the excessive angle of the self-adhesive paper passing on the transition roller 28. At the same time, when the transition roller 28 is at its farthest position from the take-up roller 33, it can be directly moved away from the line connecting the take-up roller 33 and the intermediate roller 34, so that the intermediate roller 34 is directly used as the last roller that the self-adhesive paper passes through on the take-up roller 33, reducing the number of rollers that the self-adhesive paper passes through and increasing the flatness of the self-adhesive paper winding.

[0024] In some embodiments, such as Figures 4 to 5 As shown, the output shafts at both ends of the dual-axis motor 26 pass through the first connecting block 22 and are rotatably connected to the first connecting block 22.

[0025] By adopting the above technical solution, the output shaft passes through the first connecting block 22, and the first connecting block 22 supports the output shaft, preventing vibration at the end of the output shaft when transmitting rotational motion over long distances, thereby increasing the position control accuracy.

[0026] In some embodiments, such as Figures 4 to 5 As shown, the laser detector 31 is positioned horizontally between the second connecting block 29 and the take-up roller 33.

[0027] By adopting the above technical solution, the laser detector 31 is close to the take-up roller 33 relative to the second connecting block 29, so that when the laser detector 31 detects the self-adhesive paper wound on the take-up roller 33, the second connecting block 29 is in a position relatively far away from the self-adhesive paper on the take-up roller 33, so as to prevent the second connecting block 29 from interfering with the winding of the self-adhesive paper.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
