A kind of production process of fiber-reinforced pvc hose

Abstract

The invention discloses a production process of a fiber-reinforced PVC hose, and relates to the technical field of hose production and manufacturing. Through the adjustment equipment; the adjustment equipment is provided with a magnet, and the same magnetic pole of the magnet is directed toward the center of the outer layer tube along the radial direction of the outer layer tube; the core body is passed through the inner layer tube, and the core body is provided with a magnet one along the circumference, and the same magnetic pole of the magnet one Along the radial direction of the outer tube towards the outer tube, the magnets and the magnets at the opposite ends of the magnet attract each other; the PVC hose is located between the magnet one and the magnet; step S6: make the PVC hose continue along its length Move through the adjustment device. This production process can adjust the position of the metal fiber, significantly improve the elasticity and structural strength of the metal fiber in the PVC hose, and can also realize the continuous production of the continuous hose; the inner tube and the outer tube can maintain a high The shaft degree, the quality of the produced PVC hose is better.

Description

technical field [0001] The invention relates to the technical field of hose production, in particular to a production process of a fiber-reinforced PVC hose. Background technique [0002] PVC hose is a common pipe in life, mostly used for water or ventilation. PVC hoses are generally provided with a mesh structure to improve strength. [0003] The Chinese utility model patent with the existing authorized notification number CN204141085U discloses a PVC fiber reinforced hose, including a PVC inner tube formed by extrusion, and a PVC outer tube formed by extrusion, the inner tube and the outer tube There is a fiber reinforced layer between them, and the inner tube, the fiber reinforced layer, and the outer tube are bonded together. The fiber reinforced layer is a fiber reinforced layer woven from polyester rope, and the polyester rope is woven from at least two strands of polyester yarn. A multi-strand twisted rope, each polyester filament includes multiple polyester filamen...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned prior art scheme has the following defects: in the PVC hose produced by the current production process, due to the short length of the metal fiber, the small diameter, and the random distribution of the metal fiber in the PVC hose, the elastic force of the metal fiber to the PVC hose , The enhancement effect of structural strength is not significant enough
