AI Technical Summary

Technical Problem

Existing plate-making machines suffer from water waste and poor cleaning effects during the plate-making process. Furthermore, the circulating water pipes are prone to backflow, and the one-way valves are prone to failure, resulting in poor cleaning performance.

Method used

Design a backflow prevention device for printing plate water circulation. Improve the structure of the water collection tank and the clean water tank. The circulation pipe is set above the liquid surface. Combined with the water distribution truncated cone and water distribution plate, the wastewater is slowly discharged through the water leakage hole to avoid backflow. Use filter screen and water shield to prevent impurities from entering.

Benefits of technology

It effectively avoids backflow of circulating water, improves water resource utilization, reduces production costs, ensures cleaning effect, and extends the service life of the equipment.
