Technical Field
[0001] This utility model relates to the field of aluminum plate processing technology, and in particular to an aluminum plate roller coating device. Background Technology
[0002] Roller coating equipment for metal sheets is a device that applies a paint layer to the surface of a sheet by rotating a coating roller. Compared with spray gun coating, it has the advantages of better coating effect and higher coating efficiency.
[0003] A search revealed Chinese Patent CN222789606U, which discloses a surface roller coating device for processing color-coated aluminum sheets. The device includes a housing with a groove inside. A first connecting rod is rotatably mounted on the inner wall of the groove. A second connecting rod is rotatably mounted on the outer side of the middle portion of the first connecting rod. A first gear is rotatably mounted on one outer wall of the second connecting rod, with a second gear meshing on its outer side. The outer side of the second gear is rotatably connected to the second connecting rod. A third connecting rod is rotatably mounted on the outer side of the second connecting rod, with a third gear rotatably mounted on its outer side of the middle portion. The outer side of the third gear meshes with the outer side of the second gear. A fourth connecting rod is rotatably mounted on the outer side of the other end of the third connecting rod. This solution solves the problem of the inability to adjust the distance between the rollers according to usage requirements, thus saving workers a significant amount of time and effort and reducing work efficiency.
[0004] In the aforementioned prior art solution, since the first connecting rod and the fourth connecting rod are rotatably installed inside the housing, when the length of the telescopic rod changes, the adjacent connecting rods will rotate with the change in the length of the telescopic rod. Although the distance between the two coating rollers increases, the two coating rollers are misaligned due to the rotation of the connecting rods. When the aluminum plate is between the two coating rollers, the squeezing of the coating rollers may cause deformation of the aluminum plate, resulting in damage to the aluminum plate.

[0027] The present utility model provides an aluminum plate roll coating device through improvement. The technical solution of the present utility model is as follows:
[0028] As Figures 1-3 shown, an aluminum plate roll coating device includes a roll coating box 1. Feeding and discharging grooves 7 are opened on the front and rear side walls of the roll coating box 1, and the two feeding and discharging grooves 7 are aligned with each other. A feeding component is arranged outside the roll coating box 1. The feeding component includes a fixing frame 2 and a driving motor 18. The fixing frame 2 is fixedly installed on the side wall of the roll coating box 1. An adjusting frame 3 is arranged on the top of the fixing frame 2. The adjusting frame 3 is slidably installed on the side wall of the roll coating box 1. Guide rollers 4 are rotatably installed inside both the fixing frame 2 and the adjusting frame 3. The driving motor 18 is fixedly installed on the side wall of the adjusting frame 3, and the output shaft of the driving motor 18 is fixedly connected to the side wall of the adjacent guide roller 4. The adjusting frame 3 moves downward under the action of gravity, so that the side walls of the guide rollers 4 on the fixing frame 2 and the adjusting frame 3 are mutually adhered. Place the aluminum plate to be processed between the two guide rollers 4. Through the operation of the driving motor 18, drive the adjacent guide roller 4 to rotate, and send the aluminum plate into the interior of the roll coating box 1 through the feeding and discharging groove 7. A roll coating component is arranged inside the roll coating box 1. The roll coating component includes a positioning frame 9 and a linkage rod 8. The positioning frame 9 is slidably installed inside the roll coating box 1. A mounting plate 10 is fixedly installed at the bottom end of the inner side wall of the roll coating box 1. Coating rollers 11 are rotatably installed on the inner side walls of the positioning frame 9 and the mounting plate 10. The linkage rod 8 is arranged on the top of the roll coating box 1. The linkage rod 8 is in a "冂" shape, and the bottom ends of the linkage rod 8 are respectively fixedly installed on the top wall surfaces of the positioning frame 9 and the adjusting frame 3. When the aluminum plate is placed between the two guide rollers 4, since the position of the guide roller 4 near the bottom is fixed, the adjusting frame 3 will move upward under the support of the aluminum plate. With the cooperation of the linkage rod 8, the positioning frame 9 drives the adjacent coating roller 11 to move upward synchronously, which is convenient for roll coating operations on aluminum plates of different thicknesses. The structure is simple and convenient to use.
[0029] As Figures 1-3 shown, in this embodiment, a fixing plate 5 is fixedly installed at the top end of the outer side wall of the roll coating box 1. The bottom end of the linkage rod 8 slidably penetrates through the side wall of the fixing plate 5 and is fixedly installed on the top wall surface of the adjusting frame 3. The sliding range of the adjusting frame 3 is limited by the fixing plate 5 to ensure the stable sliding of the adjusting frame 3. An extrusion spring 6 is fixedly connected to the adjacent side wall surfaces of the fixing plate 5 and the adjusting frame 3. The extrusion spring 6 is sleeved on the side wall of the linkage rod 8. By utilizing the elasticity of the extrusion spring 6, push the adjusting frame 3 downward to increase the pressure exerted by the adjusting frame 3 on the aluminum plate and ensure the stable position of the aluminum plate.
[0030] As Figures 1-3As shown, in this embodiment, a feed pump 16 is fixedly installed at the bottom of the inner wall of the roller coating box 1. A connecting pipe 14 is fixedly installed at the output end of the feed pump 16. The top end of the connecting pipe 14 is fixedly installed on the side wall of the linkage rod 8. A material flow channel 15 communicating with the inside of the connecting pipe 14 is opened inside the linkage rod 8. A spray plate 12 is fixedly installed on the top wall of the positioning frame 9. The spray plate 12 is fixedly installed on the bottom wall of the linkage rod 8.

Through the cooperation of the feed pump 16 and the connecting pipe 14, the pigment inside the roller coating box 1 is transported to the inside of the linkage rod 8. Through the cooperation of the material trough 15 and the spray nozzle 13, the pigment is evenly distributed on the side wall of the coating roller 11 near the top, which facilitates the top coating roller 11 to perform roller coating operation on the top of the aluminum plate. Since the pigment is stored at the bottom of the roller coating box 1, the coating roller 11 at the bottom can contact the pigment, so that the pigment can be evenly coated on the side wall of the coating roller 11 at the bottom, which facilitates the two coating rollers 11 to perform roller coating operation on the aluminum plate. The bottom inner wall of the roller coating box 1 is provided with an inclined groove 17, which is distributed in an inclined shape. The pigment is guided to the conveying pump 16 through the inclined groove 17, which facilitates the conveying pump 16 to transport the pigment.
[0031] The specific working method is as follows: the adjusting frame 3 moves downward under gravity, so that the side walls of the fixed frame 2 and the guide roller 4 on the adjusting frame 3 are in contact with each other. The aluminum plate to be processed is placed between the two guide rollers 4. By driving the motor 18, the adjacent guide roller 4 is driven to rotate, and the aluminum plate is sent into the interior of the roller coating box 1 through the inlet and outlet groove 7. When the aluminum plate is placed between the two guide rollers 4, since the position of the guide roller 4 near the bottom is fixed, the adjusting frame 3 will move upward under the support of the aluminum plate. With the cooperation of the linkage rod 8, the positioning frame 9 drives the adjacent coating roller 11 to move upward synchronously, which facilitates the roller coating operation of aluminum plates of different thicknesses. The structure is simple and easy to use.
