Description

Technical Field

[0001] The utility model relates to the technical field of twin-screw extruders, in particular to a mixing hopper device for a twin-screw extruder. Background Art

[0002] Extruder is a type of plastic machinery. According to the direction of the material flow in the die and the angle between the center line of the screw, the die head can be divided into right-angle die head and bevel die head. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and then form it through the die. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics, it has been widely used in the molding processing of extruded products.

[0003] For example, the utility model with publication number CN208324139U discloses a mixing and discharging hopper device for a twin-screw extruder, wherein a hopper cover is fixed to the hopper, a first motor is fixed to the hopper cover, and the output shaft of the first motor extends into the hopper and is fixedly connected to the first agitator, a second motor is fixed to the outer wall of the hopper, and the output shaft of the second motor extends into the hopper and is fixedly connected to the second agitator, a rectangular bracket is arranged outside the hopper, and the inner cavity of the rectangular bracket is connected to the discharge port of the hopper, a gear box and a third motor are both fixed to the outer wall of the rectangular bracket, and the output shaft of the third motor is connected to the input end of the gear box, and the output end of the gear box is connected to a forced-feeding twin-screw, the forced-feeding twin-screw and the vibrating air disc are both arranged in the rectangular bracket; an exhaust groove is arranged on the outer wall of the hopper. This utility model improves the production efficiency of the twin-screw extruder, stabilizes product performance, and reduces the workload of workers.

[0004] The feeding method is to pour the plastic powder directly into the hopper under load. Since there is no device in the hopper to dredge the powder, the powder is likely to accumulate on the hopper wall, causing the raw materials to be blocked, and the inner wall of the hopper is likely to stick to the inner wall, causing the raw materials to pile up together. Therefore, a twin-screw extruder mixing hopper device is proposed to address the above problems. Utility Model Content
