Abstract

The invention discloses a loading device of an extruder. The loading device comprises a feeding hopper, a material storage box and a spiral loading mechanism which is connected between the feeding hopper and the material storage box, wherein one end of the spiral loading mechanism is arranged on the bottom of the material storage box; the other end of the spiral loading mechanism is arranged above the feeding hopper; a discharging tube is connected between a spiral conveying mechanism and the feeding hopper; two crushing devices are arranged in a cross manner in the discharging tube, wherein one crushing device is arranged above the other crushing device; each crushing device comprises a first roller and a second roller which are engaged with each other, wherein the first roller and the second roller are arranged at the same height and are rotatably connected with the discharging tube, and one end of the first roller is connected with a drive device; bristles are arranged inside the discharging tube; and the bristles are matched with the first rollers and the second rollers. The loading device of the extruder disclosed by the invention can be used for crushing materials, and is beneficial to extrusion forming of materials in the extruder.

Description

technical field [0001] The invention relates to the technical field of extruder equipment, in particular to a feeding device for an extruder. Background technique [0002] The host of the plastic extruder is the extruder, which consists of an extrusion system, a transmission system and a heating and cooling system. At present, after the extruder is loaded, the material will not be crushed after entering the feeding hopper, which makes it difficult to melt the material after entering the extruder, and the material in the barrel It is also difficult for the screw to push the large-grained material smoothly, which increases the difficulty of extruding the extruder. Contents of the invention [0003] The object of the present invention is to provide a feeding device for an extruder capable of pulverizing materials. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A feeding device for an extruder, comprising a feeding hopp...
