AI Technical Summary

Technical Problem

The existing hot melt paint dispensing mechanism lacks a quantitative mechanism, making it difficult to control the amount of paint used during road marking construction. This affects the uniformity of the marking thickness, drying time, and visibility, increasing the risk of traffic accidents.

Method used

A hot melt coating quantitative feeding mechanism was designed, which includes a base, a stirring mechanism, and a quantitative mechanism. The mechanism uses a servo motor to drive the stirring rod, a temperature sensor to monitor the temperature, a liquid level sensor to control the liquid level, and an electromagnetic valve to control the discharge. Combined with a pump, it realizes quantitative delivery and stable supply of coating.

Benefits of technology

It achieves uniform mixing and quantitative feeding of hot melt coatings, improving the quality and safety of road markings, reducing energy consumption, and enhancing production convenience and operational efficiency.
