When the material passes through the coating channel, it is coated with coating. For coatings with high concentration, there is a problem of uneven and unstable coating. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a coating mechanism with arc-shaped surface contact, wherein the coating roller and the coating pressure roller are staggered on the feeding path, and the film belt forms a small arc-shaped contact surface on the coating roller, and the coating is uniformly and firmly scraped onto the arc-shaped contact surface.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the arc-shaped surface contact coating mechanism includes a frame, on which a feeding roller group for conveying materials is provided, the feeding roller group forms a feeding path, and a coating station is provided on the feeding path. The coating station is equipped with a coating roller and a coating pressure roller, wherein the coating roller and the coating pressure roller are staggered on the feeding path and the coating pressure roller is located on the coating side of the coating roller.

[0005] In this scheme, the coating roller and the coating pressure roller are staggered on the feeding path, and the material forms a small arc-shaped contact surface on the coating roller, so that the coating is evenly and firmly scraped onto the arc-shaped contact surface.

[0006] Preferably, at the coating station, the material is conveyed from front to back and the coating roller rotates from front to back, with the coating pressure roller located in front of the coating roller on the feeding path.

[0007] In this scheme, the coating is applied in the same direction and the coating is uniform.

[0008] Preferably, the coating pressure roller is located above the coating roller, a paint box is provided below the coating roller, a paint feeding roller connects the paint box and the coating roller, and the paint feeding roller is raised and lowered.

[0009] In this scheme, the paint delivery roller transfers the paint in the paint box to the coating roller, and raising or lowering the paint delivery roller moves it closer to or further away from the coating roller.

[0010] Preferably, the rotation direction of the coating roller is opposite to that of the coating roller.

[0011] In this scheme, the coating roller and the coating roller rotate in opposite directions, and the gap between them can control the coating thickness.

[0012] Preferably, the linear speed of the coating roller is lower than the feeding speed of the feeding roller assembly.

[0013] In this scheme, the coating on the surface of the coating roller is uniformly and firmly scraped onto the arc-shaped contact surface through the speed difference.

[0014] Preferably, the paint feeding roller is equipped with a paint scraping roller, which is close to or away from the paint feeding roller.

[0015] In this scheme, the amount of paint is controlled by adjusting the gap between the paint scraping roller and the paint feeding roller.

[0016] Preferably, the coating roller is mounted on a swing arm, one end of which is hinged to the frame, and the other end of which is hinged to the output shaft of the lifting cylinder.

[0017] In this scheme, the cylinder drives the swing arm to swing, causing the coating pressure roller to move closer to or away from the coating roller.

[0018] Preferably, a limit handle is provided below the swing arm.

[0019] In this design, the limit handle limits the downward pressing position of the coating roller.

[0020] Preferably, the feeding roller assembly includes a flattening roller and a guide roller. The flattening roller is located on the coating side of the coating roller, and the guide roller is located on the discharge side of the coating roller. The lowest point of the coating pressure roller is located below the line connecting the highest point of the coating roller and the highest point of the flattening roller, and the highest point of the coating roller is located above the line connecting the lowest point of the coating pressure roller and the lowest point of the guide roller.

[0021] In this scheme, the material passes around the flattening roller and the guide roller, and the coating roller and the coating pressure roller respectively contact the material to form an arc-shaped contact surface.

[0022] The beneficial effect of this utility model is that the coating roller and the coating pressure roller are staggered in the feeding path, and the material forms a small arc-shaped contact surface on the coating roller. The coating on the surface of the coating roller is effectively, evenly, and firmly scraped onto the arc-shaped contact surface through the speed difference. Therefore, this utility model has substantial features and progress compared with the prior art. Attached Figure Description

[0029] See appendix Figure 1 In this embodiment, a coating mechanism with an arc-shaped surface contact includes a frame 1. The frame 1 is provided with a feeding roller group 2 for conveying materials. The feeding roller group 2 forms a feeding path. A coating station is provided on the feeding path. The coating station is equipped with a coating roller 3 and a coating pressure roller 4. The coating pressure roller 4 is mounted on a swing arm 8. One end of the swing arm 8 is hinged to the frame 1, and the other end of the swing arm 8 is hinged to the output shaft of a lifting cylinder 9. A limit handle 10 is provided below the swing arm 8. The linear velocity of the coating roller 3 is lower than the feeding speed of the feeding roller group 2.

[0030] In this process, the material is conveyed from front to back at the coating station, and the coating roller 3 rotates from front to back. The coating pressure roller 4 is positioned in front of and above the coating roller 3 along the feeding path. A paint box 5 is located below the coating roller 3. A paint delivery roller 6 connects the paint box 5 and the coating roller 3. The paint delivery roller 6 is vertically oriented, and its rotation direction is opposite to that of the coating roller 3. The paint delivery roller 6 is equipped with… The coating roller 7 is located near or away from the coating roller 6. The feeding roller group 2 includes a flattening roller 11 and a guide roller 12. The flattening roller 11 is located on the coating side of the coating roller 3, and the guide roller 12 is located on the discharge side of the coating roller 3. The lowest point of the coating pressure roller 4 is located below the line connecting the highest point of the coating roller 3 and the highest point of the flattening roller 11, and the highest point of the coating roller 3 is located above the line connecting the lowest point of the coating pressure roller 4 and the lowest point of the guide roller 12.

[0031] In this embodiment, the coating roller 6 has coating adhering to its surface inside the coating box 5 (the coating box 5 and the coating roller 6 are mounted together on the lifting seat, which is driven by a cylinder to lift). When passing the scraping roller 7, the scraping roller 7 scrapes the coating layer on the surface of the coating roller 6 evenly. When the surface of the coating roller 6 passes the coating roller 3, the coating is transferred to the surface of the coating roller 3 and forms a coating layer of a certain thickness (the coating roller 3 and the coating roller 6 are linked). The coating roller 3 transfers the coating to the material at the coating station. The material reaches the coating station via the flattening roller 11 and then leaves the coating station via the guide roller 12. The center of the coating pressure roller 4 is misaligned with the center of the coating roller 3 in the vertical direction (this design is not limited to this).

[0032] The swing arm 8 is provided with a corresponding limit block of the limit handle 10. The limit block abuts against the handle of the limit handle 10 to restrict the swing arm 8 from swinging further. The limit handle 10 is threadedly engaged with the mounting seat on the frame 1. Rotating the extension handle of the limit handle 10 adjusts the gap between the coating roller 4 and the coating roller 3.

[0033] The coating side of the coating roller 3 is defined by the feeding path as the material conveying direction at the coating station as from front to back. If the coating roller 3 rotates in the same direction (the surface of the coating roller 3 reaches the coating station from the front and leaves the coating station to reach the rear, which is also the definition that the rotation direction of the coating roller 3 at the coating station is from front to back), then the coating side is the front side of the coating roller 3. If the coating roller 3 rotates in the opposite direction, then the coating side is the rear side of the coating roller 3.

[0034] The paint scraper roller 7 is mounted on the mounting base, which is connected to a nut. The nut is threaded with a screw, and rotating the screw can adjust the position of the paint scraper roller 7.

[0035] The linkage can be a synchronous belt and synchronous pulley, or a synchronous pulley connected to a gear, which drives the corresponding roller shaft to rotate through gear meshing.

[0036] In other alternative embodiments, the rotation direction of the coating roller 3 may be opposite to the material conveying direction (suitable for thick coating), the rotation direction of the coating material feeding roller 6 may be the same as the rotation direction of the coating roller 3, and the coating pressure roller 4 may be raised and lowered.

[0037] The above description represents the preferred embodiment of this utility model. It should be noted that the protection scope of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these modifications and substitutions are also considered to be within the protection scope of this utility model.
