AI Technical Summary

Technical Problem

Existing briquetting machines cannot automatically adjust the gap between the pressure rollers during operation, which leads to equipment damage. Furthermore, the pressure rollers need to be replaced as a whole after they wear out, increasing maintenance and material waste.

Method used

A dual-roller pressure adaptive adjustment briquetting machine was designed. The pressure is detected by a pressure sensor, the gap between the briquetting rollers is adjusted by a hydraulic cylinder, and the worn wear-resistant sleeve can be replaced individually, avoiding the need to replace the entire briquetting roller.

Benefits of technology

It enables automatic adjustment of the pressure roller spacing when the pressure is too high, preventing equipment damage, reducing replacement costs, and saving materials.

Abstract

This utility model discloses a dual-roller pressure adaptive adjustment briquetting machine, relating to the field of briquetting machine technology. It includes a base and briquetting rollers, with two rollers positioned above the base. A first vertical rod is located on the rear side of each roller, and a second vertical rod is located on the front side. A wear-resistant sleeve is fitted onto the outer wall of each roller. A rotating rod is fixedly sleeved in the middle of each roller, with one end rotatably connected to the first vertical rod. A groove is formed at the upper end of the second vertical rod, and one end of the rotating rod extends into the inner side of the groove. First fixing blocks are fixedly installed on the upper surface of the base, outside the two first vertical rods. This utility model can automatically adjust the spacing between the rollers according to the pressing pressure, effectively preventing damage caused by excessive pressure. It also allows for individual replacement of easily worn parts of the rollers without replacing the entire roller, significantly reducing replacement costs and material waste.
