With the growth of color-coated plate consumption and the continuous expansion of application areas, as well as the continuous improvement of users' requirements for their quality and performance, various new technologies for color-coated plate production have been continuously developed and applied, and the varieties of color-coated plates have gradually developed in the direction of diversification and specialization. Roller coating is an important process for processing plates.

[0003] The roller coating machine of the prior art includes a material control roller and a coating roller. The coating roller is located in front of the material control roller, and the two rollers rotate in opposite directions. The coating is applied to the sheet material by the coating roller. Therefore, the coating on the coating roller can be continuously consumed. However, since the material control roller is also continuously rotating, the coating on its surface continues to accumulate, and there is a risk of dripping. On the other hand, the roller coating machine needs to adjust the position of the material control roller relative to the coating roller to adjust the thickness of the coating material. The scraping mechanism needs to be adjusted synchronously, and the adjustment operation is cumbersome, which affects the production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0020] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] like Figure 1 It is a structural schematic diagram of the utility model, a roller coater for refrigerator food-grade liner color-coated plates, comprising a frame 1, a conveying mechanism 2, a scraping mechanism 3, a material control roller 4 and a coating roller 5, the material control roller 4 and the coating roller 5 are respectively driven by independent motors, the roller coater of the present application is a reverse roller coater, the conveying mechanism 2 is mounted on the frame 1, the conveying mechanism 2 is used to transport the color-coated plates, the material control roller 4 and the frame 1 are adjustably connected, the coating roller 5 and the frame 1 are rotatably connected, the material control roller 4 and the coating roller 5 are arranged at intervals along the transmission direction of the conveying mechanism 2, and the material control roller 4 is located behind the coating roller 5, and a material placement area 6 for placing the coating is formed above the material control roller 4 and the coating roller 5.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the roller coating machine includes a paint control driving component 7 and a mounting seat 8. The mounting seat 8 is rotatably connected to the material control roller 4, the mounting seat 8 is slidably connected to the frame 1, the paint control driving component 7 is fixedly connected to the frame 1, the output end of the paint control driving component 7 is transmission-connected to the mounting seat 8, the paint control driving component 7 is used to provide power for the material control roller 4 to approach or move away from the paint roller 5, and the paint control driving component 7 is a hydraulic cylinder.

[0023] like Figure 3 , Figure 4 As shown, the scraper mechanism 3 is located above the material control roller 4, and the scraper mechanism 3 includes a scraper plate 31. The scraper plate 31 is elastically connected to the frame 1, and the bottom surface of the scraper plate 31 is against the material control roller 4. The design of the elastically connected scraper plate 31 allows the scraper plate 31 to follow the material control roller 4 after the material control roller 4 moves, thereby avoiding the process of adjusting the scraper plate 31, thereby providing adjustment efficiency and improving continuous production efficiency.

[0024] In the initial state, the elastic element 33 is in a contracted state and has elastic potential energy, which enables the scraper plate 31 to press against the control roller 4 .

[0025] The scraper plate 31 is located on the side of the material control roller 4 close to the coating roller 5 , so that the scraped liquid can return to the material storage area 6 , avoiding the formation of a new material storage area between the scraper plate 31 and the material control roller 4 .

[0026] like Figure 3 , Figure 4 As shown, the bottom surface of the scraper plate 31 has an arc-shaped contact surface 311. Since the present application adopts an elastic connection method, the scraper plate 31 is continuously pressed against the material control roller 4. Therefore, there is no need to control the gap between the scraper plate 31 and the material control roller 4. Since the material control roller 4 is in a continuous rotation process, the contact surface 311 with an arc-shaped structure is used to reduce the wear of the scraper plate 31 and increase its service life.

[0027] like Figure 3 , Figure 4 As shown, the scraper mechanism 3 includes a connecting seat 32 and an elastic element 33, the elastic element 33 can be a spring, the connecting seat 32 is fixedly connected to the frame 1, a sliding cavity 321 is provided on the connecting seat 32 for the scraper plate 31 to move up and down, the scraper plate 31 is located in the sliding cavity 321, and the scraper plate 31 and the connecting seat 32 are slidably connected, the elastic element 33 is located in the sliding cavity 321, and one end of the elastic element 33 abuts against the scraper plate 31, and the other end abuts against the connecting seat 32.

[0028] like Figure 3 , Figure 4 As shown, a limiting cavity 322 is opened in the connecting seat 32, and the limiting cavity 322 is connected to the sliding cavity 321. The upper end of the scraper plate 31 protrudes to form a limiting block 312, and the limiting block 312 is arranged in the limiting cavity 322. The limiting block 312 can move up and down with the scraper plate 31. Through the design of the limiting block 312 and the limiting cavity 322, the scraper plate 31 can be provided with an auxiliary connection to prevent it from falling between the control roller 4 and the coating roller 5 and causing damage to the equipment.

[0029] The scraper mechanism 3 includes an adjusting block 34 and an adjusting screw 35. The adjusting block 34 is arranged in the sliding cavity 321. The elastic element 33 is arranged between the adjusting block 34 and the scraper plate 31. The lower end of the adjusting screw 35 is rotatably connected to the adjusting block 34. The adjusting screw 35 is threadedly connected to the connecting seat 32, and the upper end of the adjusting screw 35 extends to the outside of the frame 1. Through the design of the adjusting screw 35 and the adjusting block 34, the elastic force of the elastic element 33 can be adjusted to avoid the control roller 4 moving too far, which will reduce the scraping effect of the scraper plate 31.

[0030] When the paint control drive 7 is started to make the material control roller 4 approach or move away from the paint roller 5, the scraper plate 31 is pressed against the material control roller 4 under the action of the elastic force of the elastic element 33. When the elastic force of the elastic element 33 is insufficient, the adjusting screw 35 is rotated to make the adjusting block 34 approach the upper end of the scraper plate 31, that is, the elastic element 33 is compressed again to generate elastic potential energy.

[0031] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
