AI Technical Summary

Technical Problem

Existing grinding equipment for nano zinc oxide pretreatment has difficulty in efficiently grinding raw materials, especially for larger materials, where the grinding efficiency is relatively low.

Method used

The grinding mechanism combines a rotating and vertically moving pressure plate with a wear-resistant plate to grind zinc oxide raw materials. The raw materials are then screened through a filter screen and driven by a motor to rotate a shaft, which in turn drives a bevel gear and a half gear to mesh, achieving a dual grinding method of rotation and vertical crushing. The filter screen can be easily replaced or cleaned through a loading and unloading mechanism.

Benefits of technology

It improves grinding efficiency and ease of use of the equipment, ensures efficient processing of zinc oxide raw materials, and facilitates easy replacement and cleaning of the filter screen.

Abstract

This utility model relates to the field of zinc oxide pretreatment technology, specifically a grinding device for nano-zinc oxide pretreatment. It includes a housing and a grinding mechanism, with the grinding mechanism disposed on the surface of the housing. The grinding mechanism includes a filter screen disposed on the surface of the housing. A motor is fixedly mounted on the surface of the housing, and a rotating shaft is fixedly connected to the output end of the motor. A square groove is formed on the surface of the rotating shaft, and a block is slidably connected to the surface of the groove. A spring is fixedly connected to the surface of the block, and the spring is fixedly connected to the surface of the groove. A pressure plate is fixedly connected to the surface of the block. A bevel gear is fixedly connected to the surface of the rotating shaft, and a rotating rod is rotatably connected to the inner wall of the housing. This utility model, by setting up a grinding mechanism, utilizes a continuously rotating and up-and-down moving pressure plate and wear-resistant plate to grind the zinc oxide raw material. Combining rotational grinding and up-and-down rolling methods, the grinding effect is better and the efficiency is higher, effectively improving the ease of use of the equipment.
