Production device for direct-pull winding composite glass reinforced plastic pipe

Abstract

The invention discloses a production device for a direct-pull winding composite glass reinforced plastic pipe. The production device comprises a direct-pull layer unit, a front winding layer unit and a reverse winding layer unit which are sequentially distributed front and back along an inner mold. An outer mold disposed on the inner mold in a sleeving mode is arranged at the rear side of the reverse winding layer unit. The outer mold is provided with a heating mechanism. A traction unit and a cutting unit are sequentially distributed at the rear side of the outer mold. A direct-pull gluing point, a first winding point and a second winding point are all arranged in an area between a reverse winding roller and an outer mold inlet in a concentrated mode, and the area is called a processing section. The direct-pull gluing point, the first winding point and the second winding point are sequentially distributed in the processing section in a front-back approaching mode. The second winding point gets close to the outer mold inlet. By the adoption of the production device, the composite quality of the glass reinforced plastic pipe is greatly improved; and meanwhile, drawing resistance of a composite layer is greatly reduced, production can be better completed smoothly and power consumption is reduced.

Description

technical field [0001] The invention relates to a production equipment for glass steel pipes. Background technique [0002] Chinese invention patent document CN105014986A discloses a kind of extruded tape winding glass steel pipe and its manufacturing method, including the following steps: (1) tool and material preparation: prepare tubular inner mold and outer mold, first yarn dividing device, second yarn dividing device Yarn device, positive winding device, reverse winding device, dipping device, brushing device, wrapping device, heating device, pulling device and cutting machine, the outer diameter of the inner mold is smaller than the inner diameter of the outer mold, and glass fiber yarn is also prepared , stitched felt and unsaturated polyester resin are used as materials, among which, internal release agent and high temperature curing agent need to be added to unsaturated polyester resin; the yarn rolls of forward winding and reverse winding glass fiber yarn are instal...

Problems solved by technology

However, when each layer has viscous solidification, it is difficult to fully realize the above-mentioned purpose, resulting in a decline in the quality of the pipe body.

[0013] Third, when the composite layer enters the gap, the port of the outer mold forms a strong blocking effect on the glass fiber yarn, and the glass fiber may form accumulation at the port, resulting in product failure
