A plastic powder screening device

Abstract

The invention discloses a molding powder screening device. The molding powder screening device comprises a machine box, a feeding hopper, a first screening device, a first screen plate, a second screening device, a second screen plate, a driving wheel and a motor, wherein the feeding hopper is arranged above the machine box; the first screening device and the second screening device are mounted inside the machine box; a mounting frame is arranged inside the first screening device; a plurality of scraping bars are arranged inside the mounting frame; the first screen plate is mounted at the lower portion of the first screening device; a scraping plate clings to the upper surface of the first screen plate; the second screen plate is mounted at the lower portion of the second screening device; the outer walls of the first and second screening devices are each provided with a plurality of driving teeth which are matched with the driving wheel; the driving wheel is mounted on the motor through a driving shaft; a sliding plate is arranged at the bottom of the machine box. The molding powder screening device is capable of obtaining molding powder particles of which the size is relatively uniform, is capable of classifying molding powder and is simple to operate and high in screening efficiency.

Description

【Technical field】 [0001] The invention relates to auxiliary equipment for plastic powder production, in particular to the technical field of a plastic powder screening device. 【Background technique】 [0002] Powder coating is a formula material based on synthetic resin with pigments and fillers. It is a new type of decorative material that has developed rapidly in recent years. It has the characteristics of energy saving, low pollution, high efficiency, and high performance. As a solvent-free coating, it has high coating efficiency, good anti-corrosion performance, one-time film formation, convenient storage and transportation, and is increasingly popular. Thermoplastic powder coatings are obtained from thermoplastic resins, pigments, fillers, plasticizers and stabilizers through dry mixing or melt mixing, pulverization, sieving and classification. In the production process of plastic powder, the method of grinding plastic sheets or granules to form plastic powder is genera...
