Technical Field
[0001] This utility model relates to the field of roll label processing technology, and in particular to a guide roller structure for controlling the edge neatness of roll labels. Background Technology
[0002] Roll labels are labels that exist in roll form, typically made of materials such as paper or film, with a pressure-sensitive adhesive coating on the back and a release material laminated thereon. They allow for mass production, are suitable for automatic labeling machines for rapid labeling, and effectively improve production efficiency. They are widely used in various industries such as food, pharmaceuticals, logistics, and electronics to identify product names, production dates, shelf lives, model numbers, and other information.
[0003] The guide roller structure for controlling the edge neatness of roll labels typically consists of guide rollers, end rollers, and middle rollers. The end rollers may include a first half and a second half, and the middle rollers may include a first arc-shaped piece and a second arc-shaped piece. The symmetrically distributed end rollers at both ends form a containment structure to limit and guide the roll label. At the same time, the position of the end rollers can be adjusted by engaging the insertion rod and the insertion hole to accommodate labels of different widths. Overall, it can ensure that the roll label remains in the correct position during transmission and avoids deviation, thereby achieving edge neatness control.
[0004] In existing technologies, some guide roller structures for controlling the edge neatness of roll labels are prone to accumulating dust, debris, and impurities such as glue generated during label processing during long-term use. These impurities, adhering to the surface of the guide roller, alter its surface roughness and friction distribution. Most common guide roller structures on the market lack effective cleaning measures. Although some are equipped with simple cleaning devices, they often only perform basic surface cleaning and are unable to remove stubborn glue residue and tiny impurities deep in the crevices. This leads to uneven force on the roll labels during transmission, causing problems such as misalignment and wrinkles, severely affecting the neatness of the label edges, and even causing scratches on the label surface, thus reducing the product qualification rate. Therefore, a guide roller structure for controlling the edge neatness of roll labels is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a guide roller structure for controlling the edge neatness of roll labels, aiming to improve the problem of uneven force on roll labels during transmission in the prior art.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a guide roller structure for controlling the edge neatness of a roll label, including a frame 1. The frame 1 provides installation space and support for the components. Fixed posts 2 are fixedly connected to the left and right sides of the inner wall of the frame 1, and the fixed posts 2 provide limiting and guiding functions for the sliding posts 3. The sliding posts 3 are slidably connected inside the fixed posts 2. The sliding posts 3 are used to guide and limit the adjustment of the spacing of the subsequent guide wheels 23.

The bracket 5 is fixedly connected to the top of the connecting post 4. The bracket 5 provides installation space and protection for the cleaning components. A groove 6 is opened inside the bracket 5. The groove 6 provides fixing and support for the spring 7, and at the same time provides limiting and guiding functions for the slider 8.
[0034] Multiple springs 7 are fixedly connected to the inner walls of the front and rear sides of the slide 6. The springs 7 have an elastic function and provide elastic support for the slider 8. When the cleaning component below is subjected to external force, such as excessive impurities or external impact, it drives the upper slider 8 to slide back and forth, squeezing or compressing the springs 7. The elasticity of the springs 7 provides buffering. The sliders 8 are fixedly connected to the adjacent sides of the multiple springs 7. The sliders 8 provide fixation and support for the springs 9 and provide installation space for the cleaning component below. Multiple springs 9 are fixedly connected to the inner wall of the top of the slider 8. The springs 9 have an elastic function and provide elastic support for the cleaning plate 10. When the cleaning plate 10 encounters impurities that are difficult to remove in one go, it rises and slides, squeezing and buffering the springs 9.
[0035] Reference Figure 1 , Figure 2 and Figure 5 A cleaning plate 10 is fixedly connected to the bottom of spring 29. The cleaning plate 10 is used to clean dust and impurities on the surface of guide wheel 23 and guide ring 22. A slider 2 12 is fixedly connected to the left side of the cleaning plate 10. The slider 2 12 is used to limit and guide the cleaning plate 10 when it rises and slides. A groove 2 11 is opened inside the right side of the cleaning plate 10. The groove 2 11 is used to limit and guide the slider 2 12. A spring 3 13 is fixedly connected to the bottom inner wall of the groove 2 11. The spring 3 13 has an elastic function. After the slider 2 12 is subjected to force, it resets through its own elastic function. The frame 1 has an internal threaded connection with an adjustment component that facilitates the adjustment of the width according to different labels.
[0036] Reference Figure 1 and Figure 3 The adjustment assembly includes an adjustment knob 14, which allows the operator to adjust the spacing of the guide wheels 23. A connecting column 15 is fixedly connected to the bottom of the adjustment knob 14. The connecting column 15 receives force from the adjustment knob 14 and rotates, thereby causing the adjustment connecting plate 18 to move synchronously. Two connecting plates 18 are rotatably connected to the outside of the connecting column 15, and the connecting plates 18 receive force from the connecting column 15 to drive the connecting rod 19 to move. Two sliding grooves 16 are opened inside the frame 1. The sliding grooves 16 provide limiting and guiding functions for the sliders 17. The sliders 17 are slidably connected inside the sliding grooves 16. The sliders 17 provide fixing and support for the connecting rod 19, and also provide limiting and guiding functions for the connecting rod 19. The bottom of the sliders 17 is fixedly connected to the connecting rod 19. The connecting rod 19 receives tension from the connecting plate 18 to drive the lower connecting column 4 to move and adjust the spacing.
[0037] Reference Figures 1 to 3 The external sliding connection of slider 8 is to the inside of slide groove 6. Slide groove 6 provides limiting and guiding function for slider 8. The external sliding connection of cleaning plate 10 is to the inside of slider 8. Slide 8 provides limiting and guiding function for cleaning plate 10. A guide wheel 23 is rotatably connected to the right side of connecting column 4. The guide wheel 23 provides opening space for buffer groove 20. Buffer groove 20 is opened inside guide wheel 23. Buffer groove 20 provides fixing and support function for spring 4 21. Multiple spring 4 21 are fixedly connected to the left inner wall of buffer groove 20. Spring 4 21 has elastic function and provides elastic support for its guide ring 22. Guide ring 22 is fixedly connected to the right side of multiple spring 4 21. Guide ring 22 is used to guide the label.
[0038] The guide ring 22 is externally slidably connected to the inside of the buffer groove 20. The buffer groove 20 provides a limiting and guiding function for the guide ring 22. The bottom of the cleaning plate 10 is in contact with the outside of the guide ring 22. Similarly, the cleaning plate 10 is used to clean the surface of the guide ring 22. The slider 2 12 is externally slidably connected to the inside of the slide groove 2 11. The slide groove 2 11 provides a limiting and guiding function for the slider 2 12. The top of the spring 3 13 is fixedly connected to the bottom of the slider 2 12. The slider 2 12 provides a fixing and supporting function for the spring 3 13. The bottom of the connecting rod 19 is fixedly connected to the top of the sliding column 3. The sliding column 3 receives the pulling force from the connecting rod 19 and drives the right guide wheel 23 to move synchronously, thereby adjusting the spacing. The external thread of the adjusting knob 14 is connected to the inside of the frame 1. The frame 1 provides installation space for the adjusting knob 14.
[0039] Working principle: When it is necessary to clean the dust and impurities on the surface of the guide wheel 23 and guide ring 22, the roll label drives the guide wheel 23 to rotate during the transmission process. When the cleaning plate 10 encounters impurities that are difficult to remove or is subjected to external impact, the cleaning plate 10 rises or slides back and forth under the external force. When the cleaning plate 10 rises, it squeezes the slider 8 to compress and buffer the spring 9. When it slides back and forth, it drives the slider 8 to slide in the groove 6, squeezing the spring 7 for buffering. At the same time, after the force is exhausted, the elasticity of the spring 13 causes the slider 12 to return to its original position, thereby achieving the purpose of cleaning the guide wheel 23 and guide ring 22.
[0040] When the spacing of the guide wheels 23 needs to be adjusted according to different labels, the operator rotates the adjustment knob 14. The adjustment knob 14 drives the connecting column 15 to rotate, and the connecting column 15 drives the two connecting plates 18 to move. The connecting rod 19 of the connecting plates 18 moves synchronously. The sliding groove 3 16 limits and guides the sliding block 3 17, and then limits and guides the connecting rod 19. Then the connecting rod 19 pulls the sliding column 3. The sliding column 3 drives the connecting column 4 and the right guide wheel 23 to move synchronously. Thus, the purpose of adjusting the spacing of the guide wheels 23 is achieved through the linkage of the adjustment knob 14 and a series of transmission components.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
