Multi-component constant-proportion vacuum mixing device

By using a multi-component fixed-ratio vacuum mixing device, the accuracy of the dispensing ratio of materials A and B is ensured by utilizing a sealed mounting cylinder and piston assembly. Combined with the design of a spiral stirring block and scraper, the problem of pore size variation caused by residual adhesive in the dispensing nozzle is solved, thus achieving stable mixing and efficient production of insulating adhesive.

AI Technical Summary

Technical Problem

Existing devices for mixing materials A and B suffer from changes in nozzle aperture due to residual adhesive, leading to an imbalance in the adhesive dispensing ratio. This results in poor performance of the mixed insulating adhesive, increasing the risk of electrical malfunctions in the washing machine control board.

Method used

A multi-component fixed-ratio vacuum mixing device is adopted. Through the coordinated movement of the sealed mounting cylinder, the first piston, the second piston and the arc-shaped baffle, the accuracy of the feed amount and the stability of the ratio are ensured each time. Combined with the design of the spiral stirring block and the spiral scraper, a thorough and uniform mixing is achieved. The mixing environment is controlled by a vacuum pump and a pressure gauge.

Benefits of technology

This ensured accurate dispensing ratios for materials A and B, resulting in excellent performance of the mixed insulating adhesive. This improved the reliability and safety of the washing machine control board and reduced the risk of electrical failures.
