Description

Technical Field

[0001] The invention relates to the technical field of ball mills, in particular to a color aluminum coating machine. Background Art

[0002] Colored aluminum is a kind of aluminum sheet that has been painted and colored. Colored aluminum is usually painted by a roller coater, which is also called a roller coater. It is a device that uses one or more rotating rollers to apply a certain amount of paint to a flat material. It usually includes a support roller for supporting the turning, a coating roller for coating, and a take-up roller for dipping the paint and transferring it to the coating roller. Since all rollers may be contaminated with paint during the coating process, and the paint is easy to dry, the roller coater needs to be cleaned immediately after a batch of products is produced. Repeated cleaning consumes a lot of manpower, so a new coating machine is needed to solve this problem. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a color aluminum coating machine.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: a color aluminum coating machine, including a frame, a supporting roller, a coating roller, a feeding roller and a paint tray, the supporting roller, the coating roller and the feeding roller are all rotatably connected to the frame, the frame is provided with a lifting platform, the frame is provided with a lifting mechanism for driving the lifting platform to move vertically, the paint tray is fixedly connected to the lifting platform, the upgrading platform is connected with a cleaning mechanism, the cleaning mechanism includes a support tube and two cleaning plates, the two cleaning plates are arranged in a V shape on the support tube, the support tube is provided with a plurality of nozzles at intervals between the two cleaning plates, the support tube is provided with a joint for connecting a cleaning agent, and the lifting platform is provided with a moving mechanism for transferring the cleaning mechanism between the supporting roller, the coating roller and the feeding roller.

[0006] By adopting the above technical solution, the lifting mechanism can drive the upgrading platform to move downward, separate the paint tray close to the material picking roller from the material picking roller, and form a space for the cleaning mechanism to move. Then the moving mechanism will drive the cleaning mechanism to reach the material picking roller column. At this time, the material picking roller will be embedded between two cleaning plates arranged in a V shape. Cleaning tools such as brushes are arranged on the cleaning plates. The paint on the material picking roller is continuously wiped off by the rotation of the material picking roller. At the same time, the cleaning agent can be pumped into the support tube through the joint on the support tube, and sprayed on the roller through the nozzle located between the cleaning plates. The roller body of the roller coating machine is cleaned by the combination of the two. After cleaning one of the rollers, the moving mechanism will move it to another roller and start cleaning again until all the rollers are cleaned. The moving mechanism will move the cleaning mechanism as a whole to a position close to the surface of the lifting platform, so that it will not be hindered by the rollers during the resetting process. Then it moves to the initial position driven by the moving mechanism. The automatic cleaning of the rollers is realized in the above manner, which effectively saves manpower.

[0008] Preferably, the guide mechanism includes two transposition guide rails and one reset guide rail, the two transposition guide rails are respectively arranged between the pick-up roller and the coating roller and between the coating roller and the support roller, the reset guide rail is arranged at the end of the screw rod, the swinging member is fixedly connected with a guide rod for abutting against the transposition guide rail and the reset guide rail, the slide is provided with an elastic mechanism for resetting the swinging member after being pressed down by the guide mechanism, and the slide is provided with a fixing mechanism for keeping the swinging member in a retracted state. The present invention makes the guide rod abut against the transposition guide rail or the reset guide rail, so that the guide rod can drive the swinging member to rotate downward with the linear motion of the slide under the action of the inclined surface of the transposition guide rail or the reset guide rail, thereby lowering the position of the cleaning mechanism, when the cleaning mechanism reaches the specified position, the guide rod will separate from the transposition guide rail, so that the swinging member rotates upward under the action of the elastic mechanism, so that the cleaning mechanism and the roller are in contact to start the cleaning action, and the reset guide rail can push the swinging member to the lowest point through the guide rod during the process of the slide moving to the end of the screw rod.

In the present invention, when the swinging member rotates downward, the slider is pushed to slide through the connecting rod, and the spring is deformed and generates elastic force during the sliding process of the slider. After the guide rod is separated from the transposition guide rail, the spring releases the elastic force to push the slider to slide and drives the swinging member to move upward through the connecting rod.

[0010] Preferably, the fixing mechanism includes a hook and a post, the hook is rotatably connected to the end of the slide seat, the post is fixedly connected to the slider, and the lifting platform is provided with a release mechanism for releasing the fixing mechanism at the head end of the screw rod.

[0034] like Figure 1-4 As shown, a color aluminum coating machine includes a frame 1, a supporting roller 2, a coating roller 3, a feeding roller 4 and a coating tray 5. The supporting roller 2, the coating roller 3 and the feeding roller 4 are all rotatably connected to the frame 1. The frame 1 is provided with a lifting platform 6. The frame 1 is provided with a lifting mechanism for driving the lifting platform 6 to move vertically. The coating tray 5 is fixedly connected to the lifting platform 6. The lifting platform is connected with a cleaning mechanism. The cleaning mechanism includes a supporting tube 7 and two cleaning plates 8. The two cleaning plates 8 are arranged in a V shape on the supporting tube 7. The supporting tube 7 is provided with a plurality of nozzles 9 at intervals between the two cleaning plates 8. The supporting tube 7 is provided with a joint 10 for connecting a cleaning agent. The lifting platform 6 is provided with a moving mechanism for transferring the cleaning mechanism between the supporting roller 2, the coating roller 3 and the feeding roller 4.

[0035] By adopting the above technical solution, the lifting mechanism can be used to drive the upgrading platform to move downward, and the paint tray 5 close to the material taking roller 4 is separated from the material taking roller 4 to form a space for the cleaning mechanism to move. Then the moving mechanism will drive the cleaning mechanism to reach the material taking roller 4 column. At this time, the material taking roller 4 will be embedded between two cleaning plates 8 arranged in a V shape. The cleaning plate 8 is provided with cleaning tools such as brushes. The paint on the material taking roller 4 is continuously wiped off by the rotation of the material taking roller 4. At the same time, the cleaning agent can be pumped into the support tube 7 through the joint 10 on the support tube 7, and sprayed on the roller through the nozzle 9 located between the cleaning plates 8. The roller body of the roller coating machine is cleaned by the combination of the two. After cleaning one of the rollers, the moving mechanism will move it to another roller again to start cleaning again until all the rollers are cleaned. The moving mechanism will move the cleaning mechanism as a whole to a position close to the surface of the lifting platform 6, so that it will not be hindered by the roller during the resetting process. Then, it moves to the initial position driven by the moving mechanism. The automatic cleaning of the rollers is realized in the above manner, which effectively saves manpower.

[0036] The moving mechanism includes a slide 11, a screw 12 and a swinging member 13. The slide 11 is slidably connected to the lifting platform 6, the screw 12 is rotatably connected to the lifting platform 6, the slide 11 is threadedly connected to the screw 12, one end of the swinging member 13 is fixedly connected to the support tube 7, and the other end of the swinging member 13 is rotatably connected to the slide 11. The frame 1 is provided with a guiding mechanism for guiding the swinging member 13 to swing. The screw 12 can be driven by a servo motor so that the screw 12 can drive the slide 11 to move, so that the cleaning mechanism can roll on each roller. During the movement, the swinging member 13 can be rotated by the guiding mechanism to lower the position of the cleaning mechanism so that it can pass over the current roller and reattach to the roller after reaching the specified position. When the slide 11 reaches the end of the screw 12, the guiding mechanism will push the swinging member 13 to the lowest position and fix it by the fixing mechanism so that it remains at the lowest position during the movement. Then, the slide 11 is sent back to the initial position by the screw 12 flipping to achieve reset.

[0037] The guiding mechanism includes two transposition guide rails 14 and one reset guide rail 15. The two transposition guide rails 14 are respectively arranged between the material taking roller 4 and the coating roller 3 and between the coating roller 3 and the supporting roller 2. The reset guide rail 15 is arranged at the end of the screw 12. The swing member 13 is fixedly connected with a guide rod 16 for abutting against the transposition guide rails 14 and the reset guide rails 15. The slide 11 is provided with an elastic mechanism for resetting the swing member 13 after being pressed down by the guiding mechanism. The slide 11 is provided with a fixing mechanism for keeping the swing member 13 in a retracted state. By abutting the guide rod 16 against the transposition guide rail 14 or the reset guide rail 15, the guide rod 16 can move linearly with the slide 11, and the inclined surface of the transposition guide rail 14 or the reset guide rail 15 drives the swing member 13 to rotate downward, thereby lowering the position of the cleaning mechanism. When the cleaning mechanism reaches the specified position, the guide rod 16 will separate from the transposition guide rail 14, so that the swing member 13 rotates upward under the action of the elastic mechanism, so that the cleaning mechanism and the roller are in contact to start the cleaning action. The reset guide rail 15 can push the swing member 13 to the lowest point through the guide rod 16 when the slide 11 moves to the end of the screw.

[0038] The elastic mechanism includes a connecting rod 17, a slider 18 and a spring 19. The slide seat 11 is provided with a slide groove, the slider 18 is slidably connected in the slide groove, the spring 19 is arranged between the slider 18 and the slide seat 11, one end of the connecting rod 17 is rotatably connected to the middle of the swing member 13, and the other end of the connecting rod 17 is rotatably connected to the slider 18. When the swing member 13 rotates downward, the slider 18 is pushed to slide through the connecting rod 17, and the spring 19 is deformed and generates elastic force during the sliding process of the slider 18. After the guide rod 16 is separated from the transposition guide rail 14, the spring 19 releases the elastic force to push the slider 18 to slide and drives the swing member 13 to move upward through the connecting rod 17.

[0039] The fixing mechanism includes a hook 20 and a post 21. The hook 20 is rotatably connected to the end of the slide 11. The post 21 is fixedly connected to the slider 18. The lifting platform 6 is provided with a release mechanism for releasing the fixing mechanism at the head end of the screw rod 12. The head of the hook 20 has an inclined surface. When the swing member 13 rotates downward, the slider 18 drives the post 21 to move toward the hook 20. The post 21 abuts against the inclined surface of the hook 20 and uses the inclined surface to push the hook 20 to rotate, so that the post 21 enters the inner side of the hook 20. The other side of the head of the hook 20 relative to the inclined surface is a plane. Therefore, when the spring 19 drives the slider 18 to slide, the post 21 abuts against the plane of the hook 20, so that the slider 18 cannot continue to slide, thereby achieving the fixation of the swing member 13.

[0040] The release mechanism includes a guide block 22, the rotation point of the hook 20 and the slide 11 is offset from the end of the hook 20, the guide block 22 is fixedly connected to the lifting platform 6, and the guide block 22 has an inclined surface, and the end of the hook 20 abuts against the inclined surface. By using the inclined surface on the guide block 22, when the slide 11 moves toward the head end of the screw 12, the end of the hook 20 abuts against the inclined surface of the guide block 22, and rotates under the action of the inclined surface, releasing the clamping column 21 restricted on the inner side of the hook 20, so that the entire mechanism is reset and the fixation is released.

[0041] One of the cleaning plates 8 is fixedly connected to the support tube 7, and the other cleaning plate 8 is rotatably connected to the support tube 7, and a torsion spring is provided between the other cleaning plate 8 and the support tube 7. The torsion spring elastic force is used to maintain a fixed angle between the two cleaning plates 8, and after the roller is embedded between the two cleaning plates 8, the rotatable cleaning plate 8 will be pushed, so that the torsion spring generates elastic force, so that the cleaning plate 8 is pressed tightly against the roller, ensuring a better cleaning effect.

[0042] The ends of the two cleaning plates 8 are rotatably connected to rollers 27. When the roller is embedded between the two cleaning plates 8, sometimes the ends of the cleaning plates 8 will first contact the rollers, and then the two cleaning plates 8 will be gradually spread apart. The rollers 27 can reduce the friction between the ends of the cleaning plates 8 and the rollers, avoiding wear between the two.

[0043] The lifting mechanism includes a screw rod 23, two driving blocks 24 and two supporting rods 25. The two supporting rods 25 are arranged in an X shape, and the middle parts of the two supporting rods 25 are rotatably connected to each other. One end of the two supporting rods 25 is rotatably connected to the bottom of the lifting platform 6, and the other ends of the two supporting rods 25 are rotatably connected to the two driving blocks 24 respectively. The two driving blocks 24 are respectively threadedly connected to the two ends of the screw rod 23, and the two driving blocks 24 are threadedly connected to the screw rod, and the threads on the two driving blocks 24 are rotated in opposite directions. The two driving blocks 24 are slidably connected to the frame 1, and the screw rod 23 is rotatably connected to the frame 1. The screw rod 23 is driven to rotate by a motor, so that the screw rod 23 drives the two driving blocks 24 to move in opposite directions, so that the lifting platform 6 can be driven up and down by the two supporting rods 25 arranged in an X shape. The lifting mechanism can be set to two groups, which are respectively arranged on both sides of the lifting platform 6, so that the lifting platform 6 can be supported more stably.

[0044] The frame 1 is provided with a stopper 26 above the release mechanism. The stopper 26 can be used to press the swing member 13 to a lower position during the rise of the lifting platform 6, thereby reducing the occupied space of the cleaning mechanism during the operation of the machine and avoiding obstruction to the operation of the staff.

[0045] It should be noted that many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
