Inclined-type extrusion internal-formation device for plastic corrugated pipe

Abstract

The invention relates to the technical field of plastic corrugated pipes, in particular to an inclined-type extrusion internal-formation device for a plastic corrugated pipe. The technical aim is to provide the inclined-type extrusion internal-formation device for the plastic corrugated pipe. The inclined-type extrusion internal-formation device for the plastic corrugated pipe comprises a supporting rack, a fixing base and the like. The left and right portions of the bottom of the supporting rack are welded to the fixing base. The inclined-type extrusion internal-formation device for the plastic corrugated pipe has the advantages that plastic raw materials are subjected to separation-type synchronization addition through a modified plastic raw material separation, addition and stirring mechanism, and an inclined-type corrugated internal-formation mechanism pipe is in indirect linkage for inclined-type rotation extrusion and closed-type corrugated extrusion, so that extrusion is more balanced; the corrugated plastic pipe is subjected to all-directional rotation cooling through an all-directional rotation cooling mechanism, so that the spiral airflow is formed on the surface of the pipe, cooling of the plastic pipe is accelerated, and sufficient pre-mixing, inclined-type extrusion, internal corrugated rotation formation and all-directional rotation cooling for the plastic raw materials are achieved.

Description

technical field [0001] The invention relates to the technical field of plastic corrugated pipes, in particular to an inclined plastic corrugated pipe extruding inner forming device. Background technique [0002] Plastic bellows refers to a tubular elastic sensitive element made of foldable corrugated sheets made of plastic connected along the direction of folding and expansion. Bellows are widely used in instruments and meters. The main purpose is as a measuring element for pressure measuring instruments to convert pressure into Displacement or force, although the wall of the bellows is thin, the sensitivity of the bellows is high, the measuring range of the bellows is tens of Pa to tens of MPa, the open end of the bellows is fixed, the sealed end is in a free state, and the The auxiliary coil spring or reed increases the elasticity. When working, it will elongate along the length of the pipe under the action of internal pressure, so that the movable end will have a displace...

Problems solved by technology

[0006] In order to overcome the problems in the prior art that the plastic raw materials cannot be fed at the same time when adding, the mixing time is long, the stirring is uneven, the heating and smelting is not thorough, the horizontal extrusion causes too many bubbles on the wall of the bello
