Abstract

The invention discloses a novel double-screw extruder which comprises a power device, a speed reducer connected with the power device, a transmission mechanism connected with the speed reducer, a sleeve connected with the transmission mechanism, lead screws arranged in the sleeve, a machine head arranged at the top end of the sleeve, a hopper arranged on the sleeve, support frames arranged on the sleeve at equal intervals, and a material barrel arranged on the ground, wherein a runner for communicating the hopper with the sleeve is arranged in the hopper and is internally provided with a feeding lead screw, and the lead screws are in transmission connection with the transmission mechanism. Materials are transmitted to the hopper through a conveying device, compacted through the feeding lead screw in the runner, discharged into the lead screws through a filter net, and extruded by a forming mould in the machine head through the first lead screw and the second lead screw. The novel double-screw extruder has the advantages of simple structure and high working efficiency, and avoids phenomena of nonuniform material conveying and sleeve shaking.

Description

technical field [0001] The invention relates to a novel twin-screw extruder. Background technique [0002] The plastic extruder can be matched with various plastic molding auxiliary machines such as pipe, film, handle material, monofilament, flat wire, packing belt, extruded net, plate (sheet), profiled material, granulation, cable coating, etc. Various plastic extrusion molding production lines to produce various plastic products. Therefore, plastic extrusion molding machinery is one of the widely used models in the plastic processing industry no matter now or in the future; but the existing extruders have uneven material delivery and sleeve vibration, which greatly reduces the product The pass rate is high, and most of the materials are artificially charged, which not only improves the working strength, but also reduces the processing efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new twin-scre...
