Extrusion device for PE tubular product

Abstract

The invention discloses an extrusion device for PE tubular product. The extrusion device for PE tubular product comprises a heating material cylinder, a hopper, a threaded rod, a first motor, a material removing cylinder, a molding part and a trimming part. The trimming part is movably sleeved on a material discharging side of the molding part. Rectangular hollow cavities are formed in the cylindrical surface of the trimming part. Sliding block are arranged in the rectangular hollow cavities. The outer side of each sliding block is connected with a second motor and a first rotating shaft. The outer side of the second motor is fixedly connected with a connecting rod, a top block and a first rotating bead. The inner side of each sliding block is connected with a universal driving shaft. The universal driving shaft is fixedly connected with a second rotating shaft and a cutting blade. The second rotating shaft and the first rotating shaft are mutually connected through a connecting rope. The inner side of each rectangular hollow cavity is further fixedly connected with a second fixed block. A second spring is connected between the second fixed block and the top block. The cylindrical surface of the trimming part is connected with two hand shanks in a hinged mode. Each hand shank is vertically connected with a toggle plate. The toggle plate and the first rotating bead are selectively contacted. According to the extrusion device for PE tubular product, the insufficient in the prior art can be improved, and a better tubular product trimming effect is achieved.

Description

technical field [0001] The invention relates to the field of polyethylene PE pipe production equipment, in particular to a PE pipe extrusion device. Background technique [0002] my country's plastic pipes are developing rapidly, and the quality is constantly improving. At present, the plastic pipe industry based on polyvinyl chloride (PVC) pipes, polyethylene (PE) pipes and polypropylene (PPR) pipes has been initially formed. Among them, polyethylene (PE) pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas transmission and distribution, gas pipelines, electrical and telecommunications protection casings, industrial pipes, etc. due to their unique advantages. Agricultural pipes, etc. It is mainly used in urban water supply, urban gas supply and farmland irrigation and other fields. At present, the production equipment of PE pipes is relatively mature in technology and plays an important role in the production fie...
