[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5A coating mechanism for a coating machine includes: a main frame 1, on which coating components 2 for coating fabric and a limiting mechanism 3 for preventing fabric deviation are respectively arranged. The coating components 2 include a pressure roller 24, a coating roller 25, a coating liquid tank 26 fixed to the bottom plate of the main frame 1, and a recessed seat 27 fixedly installed inside the main frame 1. The recessed seat 27 has an L-shaped structure design. A drive motor 29 and a transmission mechanism are also fixedly installed on the bottom plate of the main frame 1. The central axis of the coating roller 25 rotates with the lower end of the recessed seat 27. The L-shaped recessed seat 27, with its dynamic connection, allows the center of the coating roller 25 to be positioned below the liquid surface of the coating liquid tank 26, increasing the contact area between the coating roller 25 and the liquid. This reduces the height at which the liquid is lifted, encouraging the coating roller 25 to absorb more liquid and reducing the possibility of splashing. The pressure roller 24 is located above the coating roller 25. The coating assembly 2 also includes a lifting cylinder 21 fixedly installed on the top plate of the main frame 1, and a guide post 23 fixedly installed on the inner side of the main frame 1. A U-shaped frame 22 is slidably connected to the surface of the guide post 23. Rotarily connected to the pressure roller 24, the piston rod of the lifting cylinder 21 passes through the end of the top plate of the main frame 1 and is fixedly connected to the U-shaped frame 22. The coating roller 25 is located in the inner cavity of the coating liquid tank 26, and the coating roller 25 is connected to the output shaft of the drive motor 29 through a transmission mechanism. The transmission mechanism includes a transmission shaft 211 rotatably disposed inside the recessed seat 27, a secondary synchronous belt pulley group 212 disposed in the inner cavity of the recessed seat 27, a protective cover 28 fixedly installed on the outside of the main frame 1, and a main synchronous belt also disposed in the inner cavity of the protective cover 28. The inner end of the wheel set 210 and the recessed seat 27 is synchronously driven by the auxiliary synchronous pulley set 212 and the central shaft of the coating roller 25. The drive shaft 211 passes through the outer end of the main frame 1 and is synchronously driven by the output shaft of the drive motor 29 through the main synchronous pulley set 210. The side plate of the protective cover 28 is provided with a through hole for passing through the output shaft of the drive motor 29. The drive shaft 211 is also rotatably connected to the main frame 1, and both ends of the drive shaft 211 are provided with synchronous pulleys for cooperating with the main synchronous pulley set 210 and the auxiliary synchronous pulley set 212.

[0017] The limiting mechanism 3 includes a guide rail 32 fixedly installed on the front of the main frame 1 and a connecting frame 35 fixedly installed on the side of the main frame 1. A slide block 33 is slidably connected to the surface of the guide rail 32, providing a sliding track for the slide block 33 so that the slide block 33 can slide smoothly along a fixed direction, ensuring accurate and stable adjustment of the position of the limiting roller 34. The bottom surface of the slide block 33 is rotatably equipped with the limiting roller 34, and a U-shaped connecting rod 31 is fixedly installed on the side of the slide block 33. The U-shaped connecting rod 31 is rotatably equipped with a rotating mechanism inside. A screw 37 is fixedly installed at the end of the shaft 38, and a threaded sleeve 36 is fixedly installed at the top of the connecting frame 35. The connecting frame 35 has a cavity inside for accommodating the screw 37. The axis of the threaded sleeve 36 coincides with the axis of the screw 37. The threaded sleeve 36 and the screw 37 are threadedly connected. A handwheel is fixedly installed at the outer end of the shaft 38 through the U-shaped connecting rod 31, which allows the operator to manually rotate the screw 37 to adjust the position of the limit roller 34. The overall structure is simple and convenient to operate.

[0018] Working principle: The screw 37 is rotated by the handwheel of the rotating shaft 38. The shaft of the rotating shaft 38 is rotatably connected to the U-shaped connecting rod 31, and the screw 37 is also threadedly connected to the threaded sleeve 36 of the connecting frame 35. After rotating the screw 37, the U-shaped connecting rod 31 can be driven to slide. In this way, the U-shaped connecting rod 31 pushes the slide block 33 to slide along the guide rail 32, adjusting the position of the limiting rollers 34 rotatably set on the slide block 33. The two sets of limiting rollers 34 cooperate with each other to place the fabric between the two sets of limiting rollers 34 to prevent the fabric from shifting laterally. Then, the lifting cylinder 21 is activated, and the piston rod of the lifting cylinder 21 pushes the U-shaped frame 22 and the U-shaped frame 23. The inner pressure roller 24, along the lower part of the guide post 23, clamps the fabric between the pressure roller 24 and the coating roller 25 to prevent longitudinal deviation. Finally, the drive motor 29 is started. The output shaft of the drive motor 29 drives the coating roller 25 to rotate through the main synchronous pulley set 210, the transmission shaft 211 and the auxiliary synchronous pulley set 212. The lower end of the sinker 27 is rotatably connected to the central shaft of the coating roller 25. Under the sinking action of the sinker 27, the coating roller 25 is positioned inside the coating liquid tank 26. The coating roller 25 can then rotate inside the coating liquid tank 26, causing the coating liquid to adhere to the surface of the coating roller 25, thereby coating the fabric.
