Powder coating grinding and screening machine

Abstract

The invention discloses a powder coating grinding and screening machine which comprises a device body, a driving gear, a feeding hopper, a driven gear, an upper grinding disc, a lower grinding disc and second fixing plates. The feeding hopper is arranged at the upper end of a cavity of the device body, and an output port in the lower end of the feeding hopper is formed in the lower end of the left side. The upper grinding disc is matched with the lower grinding disc and arranged at the output port in the lower end of the feeding hopper. The left side and the right side of the lower end of the lower grinding disc are provided with first notches respectively, and the second fixing plates are clamped in the first notches respectively and arranged on the left side and the right side. The second fixing plates are welded and fastened to the front plane and the rear plane of the cavity of the device body. The driven gear is fastened to the outer side of the upper grinding disc through screws, and the driving gear is engaged with the driven gear and arranged on the right side of the cavity of the device body. The powder coating grinding and screening machine facilitates automatic inputting and grinding of a powder coating; and the powder is output outwards through a screening mesh plate to be screened. The device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of powder coating processing, in particular to a powder coating grinding and screening machine. Background technique [0002] Powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. [0003] 1. Healthy and environmentally friendly, eliminating the need for various liquid chemical harmful film-forming, dispersing, wetting, leveling, anti-corrosion and anti-mildew additives added to achieve coating performance; 2. Convenient transportation and storage, ordinary coatings contain about 20 - 50% water, and in powder coatings, this part of water is only added when it is used on site, that is to say, this part of water does not need to be transported or stored. In addition, when the water-containing pai...

3. No need for preservatives. In traditional liquid coatings, there are both water and bacterial food, which are easily contaminated by bacteria.

[0004] During the processing of powder coatings, grinding is required; while the existing grinder grinds more coarse materials, and the efficiency is low; at the same time, the grinding and sieving machine does not have the function of grinding and screening, which increases the workload
