Then, the servo electric cylinder 205 in the wiping mechanism 2 is started, and its telescopic end extends and retracts, driving the solvent collection port 209 on the wiping mechanism 2 to move below the nozzle. Then, the telescopic end of the electric push rod 206 is controlled to extend, making the nozzle head parallel to the solvent collection port 209, and the action of injecting compressed air is performed to discharge the glue in the glue valve into the solvent collection port 209; then, the telescopic end of the electric push rod 206 in the wiping mechanism 2 is controlled by the glue valve control panel 202 to retract, and then the telescopic end of the servo electric cylinder 205 in the wiping mechanism 2 extends and retracts, moving the nozzle wiping block 208 on the wiping mechanism 2 below the nozzle. At this time, the telescopic end of the electric push rod 206 is controlled by the glue valve control panel 202 to extend, so that the nozzle wiping block 208 contacts the nozzle to perform the wiping action; then, the telescopic end of the electric push rod 206 in the wiping mechanism 2 is controlled by the glue valve control panel 202 to retract, and then the telescopic end of the servo electric cylinder 205 in the wiping mechanism 2 extends and retracts, moving the nozzle wiping block 208 on the wiping mechanism 2 below the nozzle. Then, the telescopic end of the electric push rod 206 is controlled to extend, making the nozzle head parallel to the solvent collection port 209; the glue valve control panel 202 injects the cleaning agent stored in the solvent barrel 2010 into the glue valve through the pipeline, and the solvent starts to decompose the glue residue in the glue valve. Then, the glue valve control panel 202 injects compressed air into the glue valve through the pipeline to discharge the solvent residue. Then, the glue valve control panel 202 injects the rinsing agent stored in the solvent barrel 2010 into the glue valve through the pipeline to remove the solvent residue. The waste solvent after cleaning the glue valve that enters the nozzle wiping block 208 enters the regeneration system 13 through the pipeline, and the cleaning effect of the glue valve is detected by the cleaning effect detection device built in the regeneration system 13, and a corresponding report is output. After the cleaning effect meets the requirements, the glue valve control panel 202 injects compressed air into the glue valve through the pipeline to dry the glue valve cavity and sends a reminder that the glue valve cleaning is completed. Then, the user removes the cleaned glue valve, and the process ends. If the cleaning effect does not meet the requirements, repeat the above operations until the cleaning is completed.
