Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a roller adjustment structure for a coating machine used in leather production. Background Technology

[0002] Coating technology involves applying one or more layers of liquid with specific functions to a surface to improve the performance of the substrate or to directly enhance the product's value by utilizing the surface properties of the coating. Coating technology typically produces products with specific functions in roll-to-roll form. Common coating methods include gravure coating and hybrid coating.

[0003] The utility model patent with authorization announcement number CN 220258515 U discloses a roller adjustment structure for a leather coating machine, which includes a housing: a coating liquid tank is installed at the bottom of the inner cavity of the housing, a movable moving plate is provided in the inner cavity of the housing, and a coating roller body is fixedly installed at the bottom of the moving plate, with the bottom of the coating roller body extending into the inner cavity of the coating liquid tank. This utility model, through an adjustment component, can drive the moving plate to move up and down, thereby driving the coating roller body and guide roller body to adjust up and down, which can meet the transmission and coating needs of leather at different heights. Furthermore, the guide roller body can be adjusted independently by a cylinder, allowing the leather to be conveyed on the coating roller with appropriate tension, thus achieving the goal of adjusting the height of the coating roller. Moreover, the tension of the conveyed leather can be adjusted by independently adjusting the guide roller. The adjustment of the guide roller meets the transmission and coating needs of leather at different heights, improving the leather coating effect.

[0004] The aforementioned disclosed structure uses a relatively complex structure to adjust the up and down movement of the coating roller, which is not only inconvenient to operate, but also complicated to align and install. Furthermore, the lack of an adjustment frame with a swing arm to connect the guide rollers makes it impossible to adjust the guide rollers on both sides to adapt to the angle of leather transfer, thus affecting the coating quality. Improvements are needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a roller adjustment structure for a coating machine used in leather production, thereby solving the problems of inconvenient alignment and installation, and limited functionality, of existing roller adjustment structures in coating machines.

[0022] This utility model provides a technical solution: a roller adjustment structure for a coating machine used in leather production. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3The system includes a frame 1, with a fixed plate 11 internally fixedly connected to it. A threaded rod 12 is threadedly installed in the middle of the fixed plate 11, and a first adjusting frame 13 is rotatably mounted on the lower end of the threaded rod 12. The first adjusting frame 13 can be adjusted directly by rotating the threaded rod 12, thus moving the coating roller 14 up and down. This facilitates installation and adjustment. During adjustment, both ends of the first adjusting frame 13 slide against the interior of the frame 1, preventing misalignment and interference, ensuring stability. The first adjusting frame 13 is slidably connected to the middle of the interior of the frame 1, and the coating roller 14 is rotatably mounted inside the first adjusting frame 13. One end of the frame 1 has a long notch 15, and a motor 16 is fixedly mounted on one end of the first adjusting frame 13. By providing the long notch 15, the coating roller 14 can be adjusted. The motor 16 is guided and avoids misalignment during vertical adjustment, ensuring safety, stability, and high adaptability. The shaft end of the motor 16 is connected to one end of the coating roller 14. The motor 16 is slidably installed inside the long notch 15. Both ends of the frame 1 are hinged with swing rods 17. One end of the swing rod 17 is fixedly connected to a second adjustment frame 18. The second adjustment frame 18 is sway-connected to both sides of the frame 1. The guide rollers 19 are rotatably installed inside the second adjustment frame 18. The guide rollers 19 are symmetrically distributed on both sides of the coating roller 14. They can be swayed and supported by the swing rods 17, thereby swinging the second adjustment frame 18 and adjusting the height of the guide rollers 19. The angle between the guide rollers 19 and the coating roller 14 will change, thus providing tension support for the conveyed leather. This design facilitates combination and is beneficial for coating production.

[0023] Please see Figure 1 , Figure 2 and Figure 4 A fixed base 2 is fixedly connected to the inner surface of the frame 1. An arc-shaped rod 21 is fixedly connected to one side of the fixed base 2. The arc-shaped rod 21 is located at one end of the outer surface of the swing rod 17 and at both ends inside the frame 1. A connecting ring 22 is fixedly connected to the outer surface of the swing rod 17. The connecting ring 22 is slidably installed on the outer surface of the arc-shaped rod 21. The arc-shaped rod is connected through the fixed base. Combined with the swing rod and the connecting ring, they can be installed together for guidance and support, ensuring the accuracy and stability of the swing adjustment, and facilitating installation and use.

[0024] Please see Figure 3 and Figure 5A tensioning spring 23 is slidably sleeved on one end of the arc-shaped rod 21. The tensioning spring 23 is tightly connected to one side of the connecting ring 22. A positioning ring 24 is slidably connected to one end of the arc-shaped rod 21. The positioning ring 24 is tightly connected to one side of the connecting ring 22. A positioning screw 25 is threaded onto one side of the positioning ring 24. The positioning screw 25 is tightly connected to the outer surface of the arc-shaped rod 21. By installing the tensioning spring and positioning ring on the arc-shaped rod and locking them together with the positioning screw, the swing rod can be elastically supported and the swing angle can be limited. This allows for stable transmission of the leather elastically. It can also limit the swing angle, which is convenient for installation and use, and is precise and efficient. The top spring 23 presses against one side of the connecting ring 22, while the positioning ring 24 presses against the other side of the connecting ring 22. Combined with the locking screw 25, the positioning is locked, which can limit the swing angle and facilitate the adjustment of the height and angle position of the guide roller 19. It is convenient to guide and support the conveyed leather, ensuring that it fits against the bottom of the coating roller 14, which is conducive to coating processing from the bottom. In addition, the swing rod 17 can combine with the connecting ring 22 to compress the top spring 23 and swing to the other side, which is conducive to elastic tension, convenient for installation and use, highly adaptable, precise and stable.
