AI Technical Summary

Technical Problem

The electronic metering device of existing polyurethane casting machines can only weigh one raw material at a time, resulting in multiple raw materials that need to be weighed in sequence, which is relatively low efficiency.

Method used

An electronic metering device for measuring proportions including a rectangular frame, a feed box, a sliding plate and an electronic meter is designed. By driving a motor and a PLC controller, the movement of the sliding plate and the electronic meter is controlled to achieve simultaneous weighing of the raw materials in the feed box on both sides.

Benefits of technology

It is achieved to shorten the weighing time interval between each raw material, optimize the working order, improve the working efficiency, and improve the stability of the discharge box through the limiting mechanism.
