[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] The utility model provides a cleaning device for a coating machine, comprising a working seat 1, the working seat 1 is rotatably connected to a guide roller 101 and a pressure roller 102, the working seat 1 is fixedly connected to a motor 103, the motor 103 is connected to the corresponding guide roller 101 and the pressure roller 102 through a rotor 104, a base film 2 is wound between the guide roller 101 and the pressure roller 102, a coating box 3 is installed on the working seat 1 above the pressure roller 102, a nozzle 301 is fixedly connected to the bottom of the coating box 3, the nozzle 301 is arranged below the pressure roller 102, and the coating box 3 is connected to the nozzle 301 through a pipeline 302, an oil cylinder 4 is installed on the left side of the nozzle 301, and the oil cylinder 4 is symmetrically distributed in the working seat 1. A slide rod 401 is slidably connected in the oil cylinder 4, and a scraper 403 is fixedly connected to the bottom of the slide rod 401 through a connecting rod 402. The position of the scraper 403 relative to the pressure roller 102 is controlled by the staff driving the oil cylinder 4. When the pressure roller 102 is cleaned, the guide roller 101 below is in a stopped state. At this time, no base film 2 is set between the pressure roller 102 and the guide roller 101, so that the waste residue on the pressure roller 102 can be cleaned in time;

[0020] When the cleaning device for the coating machine is actually used, the guide roller 101 below the pressure roller 102 is in a stopped state when the pressure roller 102 is cleaned. At this time, no base film 2 is set between the pressure roller 102 and the guide roller 101. First, the staff drives the oil cylinder 4 to drive the connecting rod 402 on the slide rod 401 to move toward the position of the pressure roller 102, and the scraper 403 below the connecting rod 402 moves toward the pressure roller 102. When the scraper 403 contacts the surface of the pressure roller 102, the oil cylinder 4 stops working. At this time, the motor 103 drives the rotary The roller 104 drives the pressure roller 102 to rotate, and cooperates with the cutter to scrape off the paint adhered to the surface of the pressure roller 102. Before the oil cylinder 4 works, the staff controls the cylinder 505 to drive the piston rod 506 to move, so that the piston rod 506 pushes the support rod 503 to slide in the guide rail 502 until the carrier box 5 on the support rod 503 moves to the position abutting against the guide roller 101, and then the scraping work is carried out again. The waste residue formed by scraping directly enters the groove 508, and then there is a vacuum cleaner 507 The scraper 403 is driven to move in the direction of the pressure roller 102 by installing the oil cylinder 4 on the left side of the pressure roller 102 in cooperation with the slide rod 401 and the connecting rod 402 structure. The movement of the scraper 403 is controlled by the staff, and then the staff drives the cylinder 505 to cooperate with the piston rod 506 to drive the support rod 503 to move in the direction of the work seat 1 until the carrier box 5 moves to the position abutting against the guide roller 101, so that the waste residue formed in the cleaning process can be effectively collected into the groove 508, and then sucked by the vacuum cleaner 507. Compared with the conventional method without a cleaning device or manual operation, the technical solution adopted by the utility model enables the paint on the pressure roller 102 to be cleaned in time, thereby ensuring the processing quality of the subsequent coating. It is reset after cleaning, which does not affect the normal progress of the subsequent coating work. The overall structure is compact and can be directly installed on the coating machine, thereby optimizing the existing working space.

[0021] like Figure 1-3 As shown, a carrying box 5 is slidably provided at a position below the pressure roller 102 in the working seat 1, a dust collector 507 is installed on the top of the carrying box 5, a groove 508 is provided on the carrying box 5, and the groove 508 is connected with the dust collector 507 through a conveying pipe 509, the working seat 1 is fixedly connected with a guide rail 502 through a rectangular plate 501, a support rod 503 is fixedly connected to the bottom of the carrying box 5, a slider 504 is fixedly connected to the bottom of the support rod 503, and the slider 504 is slidably provided in the guide rail 502, a cylinder 505 is installed on the left side of the guide rail 502, the cylinder 505 is connected to the support rod 503 through a piston rod 506, and the piston rod 506 is slidably connected in the cylinder 505, and the sliding movement of the slider 504 in the guide rail 502 guides the displacement of the support rod 503 on the left side of the working seat 1;

[0022] The effect achieved by the entire embodiment 1 is that, during use, the staff controls the cylinder 505 to drive the piston rod 506 to move, so that the piston rod 506 pushes the support rod 503 to slide in the guide rail 502 until the carrier box 5 on the support rod 503 moves to a position abutting against the guide roller 101, and then the scraping work is carried out again. The waste residue formed by scraping directly enters the groove 508, and then the vacuum cleaner 507 works, and the auxiliary conveying pipe 509 extracts the waste residue.

[0023] Working principle: When the pressure roller is being cleaned, the guide roller below is in a stopped state. At this time, no base film is set between the pressure roller and the guide roller. First, the staff drives the oil cylinder to drive the connecting rod on the slide rod to move toward the position of the pressure roller, and the scraper under the connecting rod moves toward the pressure roller. When the scraper abuts against the surface of the pressure roller, the oil cylinder stops working. At this time, the motor drives the rotor to drive the pressure roller to rotate, and cooperates with the cutter to scrape off the paint adhered to the surface of the pressure roller. Before the oil cylinder works, the staff controls the cylinder to drive the piston rod to move, so that the piston rod pushes the support rod to slide in the guide rail until the carrier box on the support rod moves to the position abutting against the guide roller, and then the scraping work is carried out again. The waste residue formed by scraping directly enters the groove, and then the vacuum cleaner works, and the auxiliary conveying pipe extracts the waste residue. After completing the cleaning of the pressure roller surface, the relevant cleaning components are reset.
