Description

Technical Field

[0002] In the modern plastic processing industry, single-screw extruders have become one of the main equipment in the production of plastic products due to their simple structure, convenient operation and efficient production. For example, the patent with the prior art publication number CN212498886U provides a single-screw extruder with a stirring device, which drives the first gear to rotate while the shaft rotates, so that the first gear drives the two second gears to rotate, so that the rotation of the reciprocating screw can drive the push plate to one side, thereby pushing the material, and pushing it to the side of the extrusion tube, so that the material will be pushed to the auger on one side of the extrusion tube, so that the material will be piled up before the auger enters the extrusion tube, and the metal sheet will be pulled to block it while the push plate moves, so that the material dropped during the movement of the push plate will be blocked by the metal sheet and will not fall to the back of the push plate; the device drives the push plate to push the material in the extrusion tube through the motor transmission to realize the feeding operation; In addition, it has the following disadvantages: For flake materials, bridging and accumulation are easy to occur during the feeding process, which affects the uniform transportation of materials. The traditional method is to crush the flake materials through crushing equipment. This method destroys the molecular structure of the material, resulting in product instability, and also increases energy consumption and labor. The screw is too single and the screw pitch is fixed, which makes it difficult to mix and compress the material evenly during the extrusion process, resulting in poor material conveying efficiency.
