Powder coating extruder

Abstract

The invention relates to the technical field of powder coating production equipment, in particular to a powder coating extruder. A storage cylinder is arranged directly above a barrel; a shaft body ofa penetrating shaft is rotationally connected with a fixed plate; a motor is fixed at the bottom of the fixed plate; a scraping plate is fixed on the shaft body of the penetrating shaft; the lower surface of the scraping plate is attached to the surface of the fixed plate; a plurality of connecting rods are fixed on the outer ring of a second bearing; the tail end of each connecting rod is fixedin a material storing and discharging pipe; a baffle ring is arranged on a rod body of a supporting rod; one end of a spring presses the lower end surface of a fixing sleeve; and the other end of thespring is pressed on a baffle ring. When the powder coating extruder is used, dynamic speed regulation of the feeding speed of a premixing barrel is achieved to guarantee that the premixing barrel isnot filled, the stirring effect of the premixing barrel is guaranteed, the uniformity of powder coating is improved, the functions of stirring and feeding pushing can be achieved through a single power mechanism, the structure is simple, and the equipment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of powder coating production equipment, in particular to a powder coating extruder. Background technique [0002] Powder coating is a new type of solvent-free, 100% solid powder coating, which has the characteristics of solvent-free, pollution-free, recyclable, environmental protection, energy and resource saving, labor intensity reduction and high mechanical strength of the coating film. The wider the application. [0003] In the production process of powder coatings, it usually includes premixing and extrusion molding to make sheet materials; [0004] However, due to the different densities of various raw materials, it is necessary to premix the various materials before entering the extruder barrel to ensure that the raw materials can evenly enter the barrel; The feeding device is used for continuous feeding, and the feeding speed needs to be consistent with the discharge speed of the extruder, or the fe...

[0004] However, due to the different densities of various raw materials, it is necessary to premix the various materials before entering the extruder barrel to ensure that the raw materials can evenly enter the barrel; The feeding device is used for continuous feeding, and the feeding speed needs to be consistent with the extruder's discharge speed, or the feeding device always fills the premixing barrel to ensure that there is always material available for the extruder barrel; but this kind of supply The material method makes it difficult for the material inside the filled premixing cylinder to be stirred, and the stirring effect is poor, which affects the uniformity of the coating
