AI Technical Summary
In existing hot-melt road marking paint dispensing devices, the springs are prone to fatigue and deformation, leading to increased quantitative errors, and the lack of an active cleaning mechanism causes the paint to easily solidify and clog.
The system employs a pusher assembly and a discharge assembly, utilizing a lead screw to drive the sleeve rod for lifting and lowering. This, combined with an active bevel gear driving a double-headed bevel gear and a bevel gear ring, achieves uniform pressure application and spiral conveying of the coating. Adhesive coating is scraped off by a scraper to prevent coating residue.
It achieves uniform coating discharge, avoids quantitative errors and coating waste caused by spring deformation, ensures accurate discharge, and reduces the risk of clogging.
