Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a coating roller structure for improving the uniformity of wet paper towels. Background Technology

[0002] Wet wipes are disposable cleaning products made primarily of water, with added detergents, disinfectants, softeners, fragrances, and other ingredients, processed using a special process. During the processing of wet wipes, the coating roller structure, which improves the uniformity of the wet wipes, can adaptively adjust according to changes in the wet wipes. It is equipped with an online detection and closed-loop control system to monitor and provide feedback adjustments in real time. At the same time, the coating roller surface has a special texture or a replaceable coating, and multiple rollers can work together to adapt to wet wipes of different materials and thicknesses, effectively improving coating uniformity and product quality.

[0003] When applying liquid to wet paper towels, the liquid to be applied is sprayed onto the surface of the coating roller through a nozzle. Then, the coating roller is rotated to apply the liquid onto the wet paper towel. Next, a scraper removes the liquid accumulated on the surface of the wet paper towel. Finally, the wet paper towel is wound up by a take-up roller.

[0004] The existing technology has the following drawbacks: In some existing equipment, the position of the nozzle is fixed, and the nozzle position cannot be changed when applying wet wipes of different sizes. The device cannot adapt to the application of wet wipes of different sizes. Furthermore, when the thickness of the wet wipes is different, the adjustment of the scraper height requires multiple bolt tightening operations, which is cumbersome, time-consuming and labor-intensive. Therefore, a coating roller structure that improves the uniformity of wet wipes is proposed to solve the above problems. Utility Model Content

The connecting block 4 has a slot corresponding to the movable nozzle 5, allowing the movable nozzle 5 to move left and right. A fixed nozzle 16 is fixedly connected to the inner wall of the connecting block 4. A rotating rod 7 is hinged to the outer wall of the movable nozzle 5 via a hinge rod 6. Since the length of the hinge rod 6 is fixed, when the movable nozzle 5 carries one end of the rotating rod 7... When moving to the left, the other end of the rotating rod 7 will move to the left along with one end of the hinge rod 6. When the moving nozzle 5 moves to the right along with one end of the rotating rod 7, the other end of the rotating rod 7 will move to the right along with one end of the hinge rod 6. The inner wall of the connecting block 4 is rotatably connected to a gear 8. The connecting block 4 has a slot corresponding to the gear 8 to facilitate the rotation of the gear 8. The outer wall of the gear 8 is meshed with a rack 9. The gear 8 can transmit the power of one set of racks 9 to another set of racks 9. The outer wall of the rack 9 is provided with a limit mechanism. The inner wall of the worktable 1 is provided with an adjustment component. The limit mechanism includes a rectangular block 10. The rectangular block 10 is fixedly connected to the outer wall of the rack 9. The inner wall of the top of the rectangular block 10 is elastically connected to an insert block 11 through a movable spring 12. When the insert block 11 moves downward, the movable spring 12 is compressed. When resetting, the elastic force of the movable spring 12 is used to reset the insert block 11.

[0036] Reference Figure 1 , Figure 6 and Figure 7 The adjustment component includes a scraper 15, which is slidably connected to the inner wall of the worktable 1. The worktable 1 has a slot corresponding to the scraper 15, allowing the scraper 15 to move vertically. The inner wall of the front end of the scraper 15 is elastically connected to a locking block 13 via a moving spring 14. When the locking block 13 moves forward, the moving spring 14 is compressed. When resetting, the elastic force of the moving spring 14 drives the locking block 13 to reset. The locking block 13 is engaged with the inner wall of the worktable 1. The worktable 1 has multiple sets of slots corresponding to the locking block 13. The locking block 13 is slidably connected to the inner wall of the scraper 15. The scraper 15 has a slot corresponding to the locking block 13, allowing the locking block 13 to move back and forth.

[0037] Reference Figures 3-5The rotating rod 7 is hinged to the outer wall of the moving nozzle 5. The rectangular block 10 is slidably connected to the inner wall of the connecting block 4. The connecting block 4 has a slot corresponding to the rectangular block 10, allowing the rectangular block 10 to move left and right. The insert block 11 is inserted into the inner wall of the connecting block 4. The connecting block 4 has a slot corresponding to the insert block 11. In its initial state, the insert block 11 is inserted into the slot of the connecting block 4. The insert block 11 is slidably connected to the inner wall of the rectangular block 10. The rectangular block 10 has a slot corresponding to the insert block 11. The corresponding slots allow the insert block 11 to move vertically. The hinge rod 6 is hinged to the outer wall of the fixed nozzle 16, and the rotating rod 7 is hinged to the outer wall of the fixed nozzle 16. Both the moving nozzle 5 and the fixed nozzle 16 are connected to the external coating tank through hoses. The outer side of the rack 9 is provided with a protrusion, which is fixedly connected to the outer wall of the moving nozzle 5. The rack 9 passes through and slides on the inner wall of the connecting block 4. The connecting block 4 has a slot corresponding to the rack 9, allowing the rack 9 to move left and right.

[0038] Working principle: When it is necessary to reduce the distance between the moving nozzles 5, manually move the insert block 11 downwards. The insert block 11 will compress the movable spring 12. When the insert block 11 separates from the slot on the connecting block 4, move the rectangular block 10 and the insert block 11 to the left. The rectangular block 10 will move the rack 9 to the left. The rack 9 will move the moving nozzles 5 and the rotating rod 7 to the left. The other end of the rotating rod 7 will move one end of the hinge rod 6 to the left. The other end of the hinge rod 6 will move the remaining sets of moving nozzles 5 to the left, reducing the distance between the moving nozzles 5. At the same time, the gear 8 will transmit power to another set of racks 9, allowing the left sets of moving nozzles 5 to move to the right along the same trajectory, reducing the distance between the moving nozzles 5. At this time, the insert block 11 coincides with the slot on the connecting block 4. Release the insert block 11 with your hand, and use the elasticity of the movable spring 12 to insert the insert block 11 into the slot of the connecting block 4, completing the limiting of the moving nozzles 5.

[0039] When it is necessary to increase the distance between the moving nozzles 5, manually move the insert block 11 downwards. When the insert block 11 separates from the slot on the connecting block 4, move the insert block 11 and the rectangular block 10 to the right. The rectangular block 10 will move the rack 9, the moving nozzles 5 and the rotating rod 7 to the right. The other end of the rotating rod 7 will move the hinge rod 6 to the right. The other end of the hinge rod 6 will move the remaining sets of moving nozzles 5 to the right, increasing the distance between the moving nozzles 5. At this time, manually release the insert block 11 and use the elastic force of the movable spring 12 to insert the insert block 11 into the slot of the connecting block 4 to complete the limiting of the moving nozzles 5. If it is necessary to adjust the distance between the moving nozzles 5 again, simply repeat the above operation steps.

[0040] When the height of the scraper 15 needs to be adjusted, manually move the locking block 13 forward. The locking block 13 will compress the moving spring 14. When the locking block 13 separates from the slot on the worktable 1, manually move the scraper 15 vertically to adjust its position. When the scraper 15 is adjusted to the required height, the locking block 13 will coincide with the slot on the worktable 1. Release the locking block 13 by hand, and use the elasticity of the moving spring 14 to insert the locking block 13 into the slot on the worktable 1, thus completing the limiting of the scraper 15.

[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.
