Automatic production apparatus for grinding powder paint

Abstract

The invention relates to automatic production equipment for powder coating grinding, which belongs to the technical field of the automatic production equipment of power coating grinding. The equipment comprises a grinding head which is arranged inside a feed inlet and forms a grinding device, wherein the grinding head is connected with a cyclone separator through an induced air channel, an outlet of the cyclone separator is connected with a dust collector which is connected with a draught fan, and a lower outlet of the cyclone separator is connected with a gyrating sieve of powder coating with thicker grain diameters. The equipment is characterized in that the lower part of the gyrating sieve is connected with a vibration sieve, the vibration sieve is elastically connected with a small cyclone dust collector at the lower part of the vibration sieve, the lower part of the small cyclone dust collector is connected with a discharge outlet, the lower part of the discharge outlet is provided with a double-valve powder flow controller used to control the evenness and the connection / disconnection of the discharge, and the lower part of the double-valve powder flow controller corresponds to a powder packing case. The equipment can realize noise reduction, automatic sieving and alarming, dust removal, weighing and packing during the production of the powder coating, can realize safety of products and steady continuous production, reduce the leakage amount of dust, and avoid the pollution to the environment.

Description

1. Technical field [0001] The invention relates to powder coating grinding automatic production equipment, and belongs to the technical field of powder coating grinding automatic production equipment. 2. Background technology [0002] At present, in the powder coating industry at home and abroad, the traditional ACM mill is basically used. This equipment was introduced into my country from the United Kingdom in the 1970s and 1980s. The traditional ACM mill consists of a grinding head, a cyclone separator, a rotary screen, a dust collector and a fan connection. The operation process is that the semi-finished powder coating from the extrusion process is crushed by the grinding head into a powder with a certain particle size distribution, and is separated by a cyclone separator. The ultrafine powder with a particle size of less than 15 microns enters the dust collector, and the remaining particles enter the rotary screen. The granular powder enters the finished product packagi...

AI Technical Summary

Problems solved by technology

[0003] 1. The grinding head is where the air inlet, the main grinding disc and the classifier are concentrated, and the noise reaches above 90 decibels

[0004] 2. There are many manual operation links and heavy workload, requiring high-quality operators;

[0005] 3. The error of manual weighing is unstable, and continuous and rapid production cannot be realized - the efficiency is low;

[0006] 4. It is difficult to control the sieve residue of powder coating, and it is easy to cause the product sieve residue to be unqualified and difficult to find;

[0007] 5. Dust leakage is relatively serious, which affects the health of operators
