Description

Technical Field

[0001] The utility model relates to the field of extrusion equipment, in particular to a twin-screw extrusion equipment. Background Art

[0002] The extruder is the core equipment of extrusion production and is widely used in food, beverage, medicine, building materials and other industries. After the material enters the screw extrusion barrel from the feed port, it is extruded out of the extrusion barrel under the action of the twin-screw extrusion, and then discharged to the outside of the machine through the outlet. However, when the existing extrusion device is used, too much material cannot be added each time. When more materials are poured in at one time, due to the inconsistent size of the materials, there will be more large-volume materials, which will cause blockage during mixed extrusion and affect the efficiency of processing and production.

[0003] A twin-screw extruder device provided according to patent application number CN202320413830.1 includes an extrusion box, the side ends of which are provided with two sets of drive motors, and the output ends of the two sets of drive motors are connected to screws; a feed port, the feed port is fixedly connected to the upper surface of the extrusion box, the maximum cross-section of the feed port is a right-angle trapezoid, and the inside of the feed port is fixedly connected with multiple sets of rotating shafts, and the two sides of the rotating shaft are respectively rotatably connected with multiple first stirring columns and second stirring columns, wherein the length of the second stirring column is greater than that of the first stirring column; multiple sets of rebound mechanisms, the rebound mechanism is arranged opposite to the first stirring column, and the rebound mechanism is located inside the feed port. Through the continuous stirring of the first stirring column and the second stirring column, the material can be effectively dispersed, the material can be prevented from being blocked, and the efficiency of processing and production can be guaranteed.

[0004] There are still some deficiencies in this patent application. In actual application, if the gap between the stirring columns is too large, the breaking effect will be insufficient and cause continued blockage. If the distance between the stirring columns is too close, the feeding speed will be slow. Too slow a feeding speed will cause the material to stick to the inner wall of the feed hopper, which is very difficult to clean. If it is not cleaned in time, it will affect the ratio of raw materials during the next pouring, and further affect the molding process of the extruded product. Therefore, a twin-screw extruder is needed to solve this problem. Utility Model Content
