Raw material crushing device for hardware coating production

Abstract

The invention discloses a raw material crushing device for hardware coating production, which comprises a crushing cylinder; the top and the bottom of the crushing cylinder are connected with two feeding hoppers and a discharging hopper correspondingly; the two feeding hoppers are symmetrically arranged in an abutting mode; two symmetrically-arranged power shafts are rotatably installed on the inner wall of the crushing cylinder; a crushing motor is installed on the front face of the crushing cylinder; and an output end of the crushing motor is fixedly connected with the end of one power shaft. According to the raw material crushing device for the hardware coating production provided by the invention, in the crushing process of a crushing roller, the power shafts of the crushing device drive a first bevel gear to rotate, the first bevel gear drives a second bevel gear to rotate, then a linkage rod drives crushing rotating blades to crush and stir preliminarily crushed raw materials, on one hand, the crushing effect and efficiency of the crushing device are enhanced on the other hand, loss caused by the fact that the crushing rotating blades directly crush the blocky raw materials is avoided, and the crushed raw materials are screened through a screening net hopper so that the needed crushed raw materials can be obtained.

Description

technical field [0001] The invention relates to the technical field of hardware paint production, in particular to a raw material crushing device for metal paint production. Background technique [0002] Hardware products refer to auxiliary and accessory finished products used in daily life and industrial production. In the early days, they were mostly made of metal materials such as gold, silver, copper, iron and tin, hence the name. To increase the aesthetics, most hardware products need to be sprayed on the outer surface of the hardware during processing to achieve the purpose of increasing the use range and service life of the hardware. [0003] Most hardware coating raw materials are lumpy. In the production process of hardware coatings, the lumpy raw materials need to be crushed and ground. The quality of raw material grinding fineness directly affects the quality of coating products. However, in the existing metal coating production equipment, most of them only carry...

AI Technical Summary

Problems solved by technology

However, in the existing metal coating production equipment, most of them only carry out preliminary crushing of block raw materials, and the dust at the feeding port is relatively large, and the grinding is not sufficient, which affects the normal operation of follow-up work.
