Environment-friendly powder coating extrusion equipment

Abstract

The invention discloses environment-friendly powder coating extrusion equipment. The environment-friendly powder coating extrusion equipment comprises a charging barrel internally provided with a screw rod and a driving mechanism used for providing power for the screw rod, a heater is arranged on the outer side of the charging barrel, the charging barrel is vertically arranged below the driving mechanism, and a feeding port is formed in the upper portion of the charging barrel; a feeding device is arranged on one side of the upper part of the charging barrel and is connected with the feeding port through a feeding pipe; the feeding device comprises a stirring barrel and a stirring shaft, and the front end of the stirring shaft is arranged in the stirring barrel; stirring blades are annularly arranged at the front end of the stirring shaft, a material filtering plate is arranged at the position, below the stirring blades, of the stirring barrel, and filtering holes are evenly distributed in the material filtering plate at intervals; dehumidifying adsorption particles are arranged in the position, above the material filtering plate, of the stirring barrel, and the portion, below the material filtering plate, of the stirring barrel communicates with the feeding pipe; and an extrusion disc is arranged at an outlet in the bottom of the charging barrel, and a scraping device is arranged on the extrusion disc. According to the extrusion equipment, efficient dehumidification of powder coating extrusion processing materials can be achieved, and meanwhile the effect of rapid extrusion cooling is achieved in cooperation with a scraping mechanism.

Description

technical field [0001] The invention belongs to the field of coating processing equipment, in particular to an environment-friendly powder coating extrusion equipment. Background technique [0002] Powder coating is a solid powder synthetic resin coating composed of solid resin and pigments, fillers and additives. Unlike ordinary solvent-based paints and water-based paints, its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation, and low energy consumption. [0003] Due to the poor thermal conductivity of the powder coating, the internal heat cannot be dissipated, which accelerates the thermal movement of the components of the powder coating, resulting in agglomeration of the powder coating. At the same time, if the air at a higher temperature in the packaging bag condenses to room temperature, there will Water analysis shows that the result of the joint action of the two causes the powder coating to ...

Problems solved by technology

[0003] Due to the poor thermal conductivity of the powder coating, the internal heat cannot be dissipated, which accelerates the thermal movement of the components of the powder coating, resulting in the agglomeration of the powder coating. Water analysis, the result of the joint action of the two, causes the powder coating to be damp and agglomerated
