AI Technical Summary

Technical Problem

The existing mixers require shutdown and disassembly/replacement after the scraper blades wear out, resulting in low production efficiency and poor scraping cleanliness, which affects production stability.

Method used

A raw material mixer with an automatic wall scraping structure was designed. Through the linkage structure of insert blocks, moving discs, control boards, inclined slides, rollers, control rods, toothed plates, gears and exchange plates, the rubber scraper can be quickly switched after wear. The compression spring is used to maintain constant pressure, ensuring the continuity and stability of the wall scraping process.

Benefits of technology

It enables quick replacement of rubber scraper blades and automatic wear compensation, avoiding downtime for disassembly, improving production efficiency and scraping effect, and ensuring efficient operation of the equipment.
