Description

Technical Field

[0001] This application belongs to the technical field of color-coated steel sheet production equipment, specifically relating to a fully automatic cleaning system for coating rollers in a color-coating workshop. Background Technology

[0002] In existing technologies, coloring of color-coated steel sheets is usually achieved through mechanical roller coating. In this process, a roller coating machine is used to apply color to the color-coated steel sheets. The coating is evenly applied to the surface of the object by rotating the rollers. Mechanical roller coating is suitable for continuous automated production, has high production efficiency, is simple to operate and easy to maintain, and is therefore widely used.

[0003] Because the paint is frequently changed during the production of color-coated steel sheets, the paint on the coating roller must be wiped clean when changing the paint. However, when cleaning and wiping while the coating roller is running, it is very easy to get caught in the rotating coating roller and cause an accident. The safety of cleaning the coating roller is low, and manual wiping is inefficient. Summary of the Invention

[0004] This application provides a fully automated cleaning system for a color coating workshop to solve the problems of low safety and low cleaning efficiency of manual cleaning of coating rollers.

[0005] The technical solution adopted in this application is: a fully automatic cleaning system for coating rollers in a color coating workshop, including a roller coating machine, wherein the roller coating machine is equipped with a material pick-up roller and a coating roller.

[0006] It also includes a protective device and a cleaning assembly. The protective device includes a rotary switch that controls the direction of the feed roller and the coating roller, and a roller gap adjustment assembly connected to the coating roller or the feed roller. The roller gap adjustment assembly drives the coating roller or the feed roller to move vertically to change the gap between the coating roller and the feed roller. The cleaning assembly includes a drive device and a cleaning component connected to the drive device. The drive device is located on the side of the roller coater, and the drive device drives the cleaning component to move laterally along the coating roller.

[0007] The fully automated cleaning system for the color printing workshop described in this application also includes the following additional technical features:

[0008] The roller coating machine includes a frame, and the roller gap adjustment assembly includes a mounting bracket fixed to the frame. The mounting bracket has an opening through which the coating roller or the take-up roller passes. The mounting bracket includes a lead screw, a lead screw seat, and a nut. The frame has a mounting port through which the lead screw passes.

[0009] The roller gap adjustment assembly also includes a drive motor or a crank handle connected to the lead screw.

[0010] The driving device includes a motor, and the cleaning component also includes a robotic arm that is drivenly connected to the motor. The cleaning component is detachably connected to the robotic arm.

[0011] The robotic arm is located on the top or side of the coating roller and moves unidirectionally along the radial direction of the coating roller.

[0012] The robotic arm is provided with a clamping end, and the cleaning component includes a cleaning plate. The cleaning plate has a proximal end fixed to the clamping end and a distal end extending along the proximal end to the end. The robotic arm clamps the cleaning plate so that the distal end is attached to a portion of the coating roller.

[0013] The distal end is equipped with a flexible wiping material.

[0014] The cleaning system also includes a waste trough, which is detachably connected to the bottom of the frame.

[0015] The waste trough is arc-shaped, and its inner diameter is larger than that of the coating roller.

[0016] The waste trough includes a main body and a baffle, the baffle being detachably connected to the main body.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. By incorporating protective devices and cleaning components, the cleaning of the feed roller and coating roller is safely accomplished. A direction switch controls the rotation of the feed roller and coating roller. During cleaning of the coating roller, the direction is reversed via the direction switch, ensuring that the rotation direction of the feed roller and coating roller is opposite to that of the coating roller. This prevents the cleaning components from being caught in the process and also prevents workers from being caught when wiping with cleaning tools. A drive unit drives the cleaning components to clean the coating roller, eliminating the need for manual cleaning, improving cleaning safety, and simultaneously enhancing the mechanization of the cleaning system and increasing cleaning efficiency.

[0019] 2. The distance between the feed roller and the coating roller is adjusted by adjusting the lead screw nut. This increases the distance between the feed roller and the coating roller when cleaning is required, facilitating cleaning. Furthermore, increasing the distance improves cleaning safety and ensures a more thorough cleaning of the coating roller.

[0020] 3. The coating roller is cleaned by a robotic arm that drives the cleaning unit, avoiding manual cleaning, thus ensuring the safety of the cleaning work, improving the mechanization of the cleaning device, reducing labor costs, and improving cleaning efficiency.

[0021] 4. By setting up a waste trough, it is easy to collect cleaning waste, which avoids waste splashing onto the ground or other devices and is difficult to clean, thus reducing the cleaning burden. In addition, the baffle can be removed to facilitate the washing of the waste trough and realize recycling. Attached Figure Description

[0037] This application provides a fully automatic cleaning system for coating rollers in a color coating workshop, such as... Figure 1 , Figure 2 As shown, the system includes a roller coater 1, which is equipped with a feed roller 12 and a coating roller 13. It also includes a protective device and a cleaning assembly. The protective device includes a rotary switch that controls the direction of the feed roller 12 and the coating roller 13, and a roller gap adjustment assembly connected to the coating roller 13 or the feed roller 12. The roller gap adjustment assembly drives the coating roller 13 or the feed roller 12 to move vertically to change the gap between the coating roller 13 and the feed roller 12. The cleaning assembly includes a drive device and a cleaning component 4 connected to the drive device. The drive device is located on the side of the roller coater 1 and drives the cleaning component 4 to move laterally along the coating roller 13.

[0038] The cleaning of the coating roller 13 is safely accomplished by incorporating protective devices and cleaning components. A direction switch controls the rotation of the feed roller 12 and the coating roller 13. During cleaning, the direction switch reverses the rotation of the feed roller 12 and the coating roller 13, ensuring they rotate in the opposite direction to the direction of the coating. This prevents the cleaning component 4 from being caught in the coating and also prevents workers from being caught when using hand cleaning tools. A drive unit drives the cleaning component 4 to clean the coating roller 13, eliminating the need for manual cleaning, improving safety, and enhancing the mechanization and efficiency of the cleaning system.

[0039] In one embodiment, the roller coating machine 1 includes a frame 11, and the roller gap adjustment assembly includes a mounting frame 2 fixed to the frame 11. The mounting frame 2 has an opening 25 through which the coating roller 13 or the take-up roller 12 passes. The mounting frame 2 includes a lead screw 21, a lead screw seat 22, and a nut 23. The frame 11 has a mounting port through which the lead screw 21 passes.

[0040] The distance between the feed roller 12 and the coating roller 13 is adjusted by adjusting the lead screw 21 and nut 23. Specifically, when cleaning the coating roller 13 is required, the distance between the feed roller 12 and the coating roller 13 is increased by adjusting the lead screw 21 and nut 23, thus facilitating cleaning of the coating roller 13. Furthermore, increasing the distance between the feed roller 12 and the coating roller 13 improves cleaning safety and allows for more thorough cleaning of the coating roller 13.

[0041] Furthermore, the roller gap adjustment assembly also includes a drive motor or a crank handle 24 connected to the lead screw 21.

[0042] The distance between the material take-up roller 12 and the coating roller 13 is changed by rotating the lead screw 21 through the drive motor or by manually shaking the handle 24.

[0043] It is understandable that the roller gap adjustment component can be connected to either the take-up roller 12 or the coating roller 13, depending on the position of the take-up roller 12 and the coating roller 13 on the frame 11 and the installation space.

[0044] In one embodiment, the drive device includes a motor, and the cleaning assembly also includes a robotic arm 3 that is driven and connected to the motor. The cleaning component 4 is detachably connected to the robotic arm 3.

[0045] The robotic arm 3 drives the cleaning component 4 to clean the coating roller 13, avoiding manual cleaning, thus ensuring the safety of the cleaning work, improving the mechanization of the cleaning device, reducing labor costs, and improving cleaning efficiency.

[0046] Preferably, the robotic arm 3 is located on the top or side of the coating roller 13 and moves unidirectionally along the radial direction of the coating roller 13.

[0047] This avoids the cleaning component 4 from moving back and forth, which would result in incomplete wiping and further improves cleaning efficiency. The movement method is also simple and easy to control the robotic arm 3.

[0048] Furthermore, the robotic arm 3 is provided with a clamping end 31, and the cleaning component 4 includes a cleaning plate. The cleaning plate is provided with a proximal end 41 fixed to the clamping end 31 and a distal end 42 extending along the proximal end 41 to the end. The robotic arm 3 clamps the cleaning plate so that the distal end 42 is attached to a portion of the coating roller 13.

[0049] The robotic arm 3 is kept at a certain distance from the material picking roller 12 and the coating roller 13 to avoid collisions with the coating roller 13, while increasing the contact area between the cleaning component 4 and the coating roller 13 to speed up the cleaning process.

[0050] Understandably, the length of the robotic arm 3 is determined based on the length of the coating roller 13, so that the robotic arm 3 can drive the cleaning component 4 to wipe and clean the coating roller 13 as a whole.

[0051] Preferably, the distal end 42 is provided with a flexible wiping material.

[0052] Use a flexible wiping material to clean the coating roller 13 to avoid scratches or other damage to the coating roller 13.

[0053] In one embodiment, the cleaning system also includes a waste trough 6, which is detachably connected to the bottom of the frame 11.

[0054] When not in use, the waste trough 6 can be removed for cleaning without affecting the normal operation of the machine.

[0055] Preferably, the waste trough 6 is arc-shaped, and the inner diameter of the waste trough 6 is larger than the inner diameter of the coating roller 13.

[0056] To prevent cleaning waste from falling outside the waste tank 6, thus reducing the cleaning burden.

[0057] Preferably, the waste trough 6 includes a main body and a baffle, the baffle being detachably connected to the main body.

[0058] By setting up the waste trough 6, it is easy to receive cleaning waste, avoid the waste from splashing onto the ground or other devices and making it difficult to clean, reduce the cleaning burden, and make it easy to wash the waste trough 6 after the baffle is removed, so as to achieve recycling.

[0059] In another embodiment, before the cleaning work begins, the distance between the take-up roller 12 and the coating roller 13 is increased by the roller gap adjustment component, and the waste trough 6 is installed between the take-up roller 12 and the coating roller 13, that is, the waste trough 6 is located at the bottom of the coating roller 13, which facilitates the improvement of the waste receiving effect.

[0060] In one embodiment, the cleaning system further includes a linear slide rail located outside the frame 11. The linear slide rail is provided with a slider 51 connected to the robotic arm 3. The motor drives the slider 51 to move along the linear slide rail to move the robotic arm 3 in the vertical direction, thereby moving the cleaning component 4 to the corresponding position.

[0061] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0062] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0063] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
