Feeding device of powder coating extruder

Abstract

The invention provides a feeding device of a powder coating extruder. The feeding device is characterized by comprising a hopper, a vibration device, a square discharging pipe and a base, and the hopper comprises an inner-layer hopper and an outer-layer hopper; the vibration device comprises a vibration motor, a force transmission frame and an elastic adjusting piece, wherein a magnetic support isarranged in the square discharging pipe; and the base comprises a bottom frame, a sliding guide rail, an interface, a driving air cylinder, a telescopic baffle and a limiting plate. The feeding device of the powder coating extruder is novel in structural design; the inner-layer hopper and the outer-layer hopper are adopted, and the vibration device is combined with the reciprocating motion of thedriving air cylinder of the base, so that the phenomenon that the hoppers are blocked is greatly improved; a filter screen of the inner-layer hopper avoids the collapse phenomenon of materials, andthe materials can be uniformly discharged; and the magnetic support in a square material storage pipe can effectively remove iron-containing impurities in the materials, and greatly improves the quality of powder coating.

Description

technical field [0001] The present application relates to the field of powder coating devices, in particular to a feeding device for a powder coating extruder. Background technique [0002] In the existing powder coating production process, there is a production process of adding a mixture of various raw materials into an extruder for melt extrusion. In this process, the existing extruder first passes the mixture into the extrusion module through the feed hopper, and the feed hopper is used to provide the mixture to the extrusion module. However, there is a problem in the existing extruder, that is, the arching and blocking of materials in the feed hopper, and the intermittent feeding. [0003] At present, powder coating manufacturing enterprises often use employees to deal with this problem with rubber sticks, resulting in waste of personnel. At the same time, due to material breakage, the screw is idling, and the heater is heated for a long time. The temperature will rise...

Problems solved by technology

However, there is a problem in the existing extruder, that is, the material in the feed hopper is arched and blocked, and the feeding is intermittent.

[0003] At present, powder coating manufacturing enterprises often use employees to deal with this problem with rubber sticks, resulting in waste of personnel. At the same time, due to material breakage, the screw is idling, and the heater is heated for a long time. The temperature will rise due to no material entering, resulting in residues in the screw. Material coking seriously affects product quality
