Problems solved by technology

[0002] In the traditional roller extrusion granulator, the material falls freely between the two rollers with the help of gravity. Due to the fluidity of the material, the material moves in the direction of the least resistance, and the material will return upward during the extrusion process, so this This extrusion granulation process has small output, low molding pressure, poor product quality and low production efficiency

Embodiment Construction

[0013] The invention is a novel screw forced feeding system, which is mainly used in the technical field of roller extrusion granulation. The powdery material treated by the front end enters the lower hopper 5 through the feeding port on the lower hopper cover 3 . The variable frequency motor 1 drives the extrusion screw 6 to rotate through the adjustable connecting flange 4 to form extrusion on the material 10 .

[0014] see figure 1 , the concrete structure of the present invention is:

[0015] A screw forced feeding system, including a motor 1, a bearing seat 2, a lower hopper cover 3, a connecting flange 4, a lower hopper for storing materials 5, an extrusion screw 6, a support bracket 7, a vent cap 8 and an extrusion Pressure roller 9; Wherein,

[0016] The motor 1 is connected to the lower hopper cover 3 through the bearing seat 2, and drives the extrusion screw 6 to rotate through the connecting flange 4, so as to give a forced downward extrusion force to the materia...

Abstract

The invention relates to a feed device, in particular to a spiral forced feed system, which is characterized by comprising a motor, a bearing seat, a blanking hopper cover, a connection flange, a blanking hopper for storing a material, an extrusion spiral, a support for supporting, a ventilation cap and extrusion rollers, wherein the motor is connected with the blanking hopper cover through the bearing seat, the connection flange drives the extrusion spiral to rotate so as to provide forced downward extrusion force to the material in the blanking hopper, the blanking hopper cover is arranged on the blanking hopper so as to support the bearing seat and the motor, the ventilation cap is connected on the blanking hopper cover for ventilation and filtration, and the extrusion rollers are connected on the support so as to extrude the material to be molded. The spiral forced feed system discloses by the invention has the advantages that the extrusion pressure is improved, the quality of a product is improved, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a feeding device, in particular to a screw forced feeding system. Background technique [0002] In the traditional roller extrusion granulator, the material falls freely between the two rollers with the help of gravity. Due to the fluidity of the material, the material moves in the direction of the least resistance, and the material will return upward during the extrusion process, so this This extrusion granulation process has small output, low molding pressure, poor product quality and low production efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a screw forced feeding system to overcome the defects in the prior art. [0004] The technical solution of the present invention is: a screw forced feeding system, which is characterized in that it includes a motor, a bearing seat, a lower hopper cover, a connecting flange, a lower hopper for storing materials, an extrusion screw, ...
