HDPE (high-density polyethylene) winding and reinforcing structural wall B-type pipe molding machine capable of demolding automatically

Abstract

The invention discloses an HDPE (high-density polyethylene) winding and reinforcing structural wall B-type pipe molding machine capable of demolding automatically. The HDPE winding and reinforcing structural wall B-type pipe molding machine capable of demolding automatically comprises a main shaft, wherein the main shaft is horizontally connected with a base by a shaft sleeve; one end of the main shaft is connected with a main shaft drive motor in a drive mode; a multi-shaft gearbox, a mold angle guide disc and a tail disc are sequentially connected from the connection part of the main shaft and the shaft sleeve to the other end of the main shaft coaxially; the main shaft is also fixedly connected with an angle driving device; the mold angle guide disc and the angle driving device are connected in a drive mode; the HDPE winding and reinforcing structural wall B-type pipe molding machine also comprises a plurality of autorotation mold shafts connected to the rear disc; the other ends of the autorotation mold shaft are connected to a drive shaft of the multi-shaft gearbox; an included angle of 5-30 degrees is formed between the autorotation mold shafts and the main shaft. The HDPE winding and reinforcing structural wall B-type pipe molding machine provided by the invention can demold automatically, omits the device, manpower and time input of a demolding technology, and reduces the product manufacturing cost effectively.

Description

technical field [0001] The invention relates to the technical field of B-shaped pipes with HDPE winding and reinforced structure walls, in particular to a B-shaped pipe forming machine with automatic demoulding of HDPE winding and reinforced structure walls. Background technique [0002] HDPE winding reinforced structure wall B-type pipe, also known as carat pipe, is made of high-density polyethylene (HDPE) as the main raw material, adopts hot winding poplar technology, and uses polypropylene (PP) single-wall corrugated pipe as the supporting structure. The special structural wall pipe with high resistance to external pressure has the advantages of high weld quality, excellent installation performance, good flexibility, high strength, corrosion resistance, aging resistance, long service life, recyclable use, and smooth inner wall of the pipe. It has incomparable advantages over other pipes in terms of municipal sewage discharge and chemical sewage discharge. [0003] The HD...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a B-type pipe forming machine with automatic demoulding of HDPE winding and reinforced structure wall, which can solve the problem of high winding speed of the existing HDPE winding and reinforced structure wall B-type pipe forming machine on a smooth cylindrical mold. For high-density polyethylene and polypropylene, the product needs to be cooled and demolded after winding, resulting in high equipment prices and operating costs, and the length of the product is limited by the mold, making the demoulding process difficult.
