Plastic-steel winding pipe production line

Abstract

The invention relates to a plastic-steel winding pipe production line, and belongs to the technical field of water pipe production equipment. The production line comprises a cutting device, the cutting device comprises a bottom plate, two conveying devices which are connected end to end are arranged on the bottom plate, a cutting piece used for cutting a pipeline is arranged between the two conveying devices, the cutting piece comprises upright posts, frame bodies are rotationally connected to the ends, far away from the bottom plate, of the upright posts on the two sides, a first driving piece is arranged on the bottom plate, a plurality of laser knives are arranged in the frame bodies, sliding rods are arranged in the frame bodies and located at the positions of the laser knives correspondingly, one ends of the sliding rods penetrate and are in sliding connection with the frame bodies, the other ends of the sliding rods are arranged towards the positions where the circle centers of the frame bodies are located, the laser knives are connected to the ends, close to the circle centers of the frame bodies, of the sliding rods, second driving pieces are arranged on the frame bodies, the sliding rods are driven by the second driving pieces to move on the frame bodies, and a laser head is driven to adjust the distance between the laser head and the pipeline, so that the laser head is applicable to pipelines with different diameters, and the using effect of he cutting device is improved.

Description

technical field [0001] The invention relates to the technical field of water pipe production equipment, in particular to a plastic-steel winding pipe production line. Background technique [0002] Polyethylene-plastic-steel winding pipe (SRWPE) is made of steel-plastic composite special-shaped strips that are spirally wound and welded (extrusion welding on the lap joint), and its inner wall is smooth and flat. This kind of pipe has the advantages of corrosion resistance, light weight, easy installation, large flow rate, long life (50 years), etc. It can replace pipes made of high energy consumption materials (cement, cast iron, ceramics, etc.), and is an environmentally friendly green product. [0003] The Chinese patent with the authorized notification number CN202428673U discloses a large-diameter plastic-steel flat-wall winding drainage pipe production line, which includes two parts: a strip production line and a drainage pipe production line; the strip production line is...

Problems solved by technology

[0005] But its disadvantage is that when the cutting device is used to cut pipes with smaller diameters, the position between the laser knife and the pipe will be far away, which reduces the strength of the laser knife when cutting the pipe, thereby reducing the cutting device. The cutting effect when cutting the pipe
