Description

Technical Field

[0001] The present invention relates to a cleaning device, specifically an automatic cleaning device for the paint tray and coating roller of a color coating machine. Background Art

[0002] The coating performance is one of the important characteristics of color coated steel sheets. The coating performance is not only related to the production process of color coated steel sheets, but also closely related to the quality of the paint itself. Therefore, the cleaning degree of the paint in the rollers and the paint tray is a key factor affecting the coating quality of color coated strip steel. At present, the domestic technology for the automatic cleaning of the paint tray and coating roller of a color coating machine is blank, and the cleaning of the color coating unit in the painting room abroad also involves manual participation. After painting with one type of paint and then changing to another, the relevant areas of the roller coating equipment need to be automatically cleaned. After the color coating is completed and the paint type is changed, the residual paint remaining in the coating roller and the paint tray needs to be recovered and cleaned.

[0003] Currently, the cleaning of color coating units is all carried out by manual cleaning methods. Since most color coating paints are toxic materials and harmful to the environment and the human body, the color coating machine is located in the painting room, and the painting is equipped with a VOC treatment system to prevent harmful gases from polluting the environment. Since different types (colors) of paints need to be applied according to different color coating requirements during the color coating production process, the paint type needs to be changed. Personnel need to enter the painting room for operation, use paint cleaning agents to clean different areas, and most of the cleaning agents are harmful substances and cause great harm to the human body. The personnel cleaning work takes a long time and has a lot of work content. Paint cleaning is a high-risk process. Currently, before changing the paint, manual cleaning requires wearing protective equipment according to the operation instruction manual before entering the painting room for work. Cleaning areas: the strip roller, the coating roller, the paint tray, the paint inlet pipe, and the reversing roller. There are many cleaning areas and a large amount of work. The color coating unit often needs to change colors during production. When changing colors, the paint pump and pipes need to be manually disassembled and assembled, and the agitator needs to be disassembled and assembled.

[0020] The cleaning agent metering and supply system 3 adopts a one - use - one - standby mode, and is equipped with a metering pump 401, a system pressure gauge 402, and a solenoid valve 403. The cleaning agent is pumped out of the storage bucket by the metering pump 401, and the solenoid valve 403 controls the on - off of the pipeline.

[0021] The cleaning agent metering and supply system 3 supplies the cleaning agent quantitatively, and is transported to the cleaning agent drip head 103 of the robot gripper through a pipeline to achieve quantitative control of the cleaning agent.

[0022] Embodiment 2 The usage method of the automatic cleaning device for the paint tray and coating roller of the color coating machine of the present invention includes the following steps: 1. Paint recovery: After the color coating machine stops operating, the automatic cleaning device for the paint tray and coating roller starts operating.

[0023] 2. The cleaning robot arm 1 grabs the wiping cloth at a fixed point from the wiping cloth automatic supply system 2. Scrape the remaining paint adhering to the strip roller 10 and the coating roller 11. The strip roller 10 and the coating roller 11 rotate, and the speed is adjustable. The gripper drives the wiping cloth 205 to move linearly relative to the axis to scrape the paint on the roller body respectively. Ensure that most of the paint drips into the paint tray. The number of scraping times can be set according to the paint characteristics (viscosity).

[0024] The paint tray 9 exits from the working position (under the roller) to outside the roller, and the robot arm drives the wiping cloth 205 to scrape the paint on the four walls and the bottom surface of the paint tray towards the paint overflow port, ensuring that most of the paint flows back to the paint recovery bucket 6. For next use, it saves production costs.

[0025] After the paint reflux ends, the paint tray 9 enters from the exit position to the working position under the roller. The system switches to the cleaning mode, and the drain port moves to the cleaning agent recovery bucket 7. The robot arm places the used wiping cloth 205 in the wiping cloth recycling box 8. The wiping cloth 205 is composed of corrosion - resistant sponge and can be reused after cleaning.

[0026] 3. Roller cleaning: The cleaning robot arm 1 grabs the wiping cloth at a fixed point from the wiping cloth automatic supply system 2. The cleaning robot arm 1 supplies the cleaning agent to the cleaning agent drip head 103 quantitatively through the cleaning agent metering and supply system 3, drips the cleaning agent on the wiping cloth 205, and uses the cleaning agent to wet - wipe the roller body and the shoulder part. After repeating the counting according to the paint characteristics, replace the wiping cloth. After the wet - wiping ends, the cleaning robot arm 1 grabs the wiping cloth at a fixed point from the wiping cloth automatic supply system 2. Dry - wipe the roller body and the shoulder to wipe off the remaining cleaning agent and paint.

[0027] 4. Cleaning of the paint tray: The paint tray 9 exits from the working position (beneath the roller) to outside the roller, and the robotic arm drives the wiping cloth 205 to scrape the paint on the four walls and the bottom surface of the paint tray towards the paint overflow port of the paint tray, scraping the mixture of the cleaning agent and the paint into the cleaning agent recovery bucket 7. Scrape repeatedly until the paint tray is clean.

[0028] After the paint tray is clean, the paint tray enters from the exit position to the working position beneath the roller. The system resets and waits for the next cleaning.

[0029] The present invention has substantial features and remarkable technical progress. The automatic cleaning device for the paint tray and coating rollers of the color coating machine of the present invention can achieve automatic dripping of the cleaning agent, automatic replacement of the cleaning wiping head, automatic cleaning of the coating roller, the strip feeding roller, the metering roller, etc., and can also clean the paint tray.
