Powder coating grinding device

Abstract

The invention discloses a powder coating grinding device. The powder coating grinding device comprises a shell, a plurality of grinding bodies, grinding plates, a rotating shaft, a motor and a cold water supply unit; the multiple grinding bodies are longitudinally arranged in the shell and fixed to the shell through connecting pieces; the grinding bodies are circular truncated cone-shaped pieces and are each provided with a cavity in a circular truncated cone shape, and the bottom of each grinding body is provided with a discharge hole; the grinding plates are arranged in the cavities of the grinding bodies; the middles of the grinding plates are provided with assembly holes; the rotating shaft penetrates through the assembly holes and is fixedly connected with the grinding plates, and oneend of the rotating shaft is connected with the motor; annular cavities are formed in the grinding plates, the grinding plates are provided with water passing pipelines, and the water passing pipelines communicate with the cavities and are further connected with the cold water supply unit; and the upper portion of the shell is provided with a feed inlet which is located above the grinding plates.The powder coating grinding device improves the grinding quality and avoids adverse effects of the grinding temperature to powder coating.

Description

technical field [0001] The invention relates to the technical field of paint processing, in particular to a powder paint milling device. Background technique [0002] With the rapid development of people's life, powder coatings are widely used in daily life. Powder coatings are in a completely different form from general coatings, and they exist in the state of fine powder. In the production process of powder coatings, the raw materials need to be hot-melt extruded and finely pulverized, which requires the use of powder coating milling equipment. The smaller the diameter of the powder coating particles, the better the performance, so the powder coating milling equipment appears Crucially, the milling effect achieved by the existing powder coating milling devices is not ideal, and often accompanied by excessive temperature during the milling process, it is easy to adversely affect the quality of the powder coating, and, There are also the shortcomings of powder coatings bein...

In the production process of powder coatings, the raw materials need to be hot-melt extruded and finely pulverized, which requires the use of powder coating milling equipment. The smaller the diameter of the powder coating particles, the better the performance, so the powder coating milling equipment appears Crucially, the milling effect achieved by the existing powder coating milling devices is not ideal, and often accompanied by excessive temperature during the milling process, it is easy to adversely affect the quality of the powder coating, and, There are also the shortcomings of powder coatings being easy to agglomerate after grinding, grinding is not meticulous, and grinding efficiency is low
