Device for production of corrosion-resisting glass fiber-reinforced plastic pipe

Abstract

The invention discloses a device for production of a corrosion-resisting glass fiber-reinforced plastic pipe. The device comprises a support, traction devices arranged on the support, a transmission belt rotatingly connected to the traction devices, and other parts of die cavity devices, a first glue-brushing device, a first glue-injection port, a first weaving device, a second glue-injection port, a first linear-yarn device, a second glue-brushing device, a third glue-injection port, a circumferential-yarn left-turn winding device, a forth glue-injection port, a circumferential-yarn right-turn winding device, a fifth glue-injection port, a second linear-yarn device, a third glue-brushing device, a sixth glue-injection port, a second weaving device, a seventh glue-injection port and an internal felt-coating device, wherein the other parts are orderly arranged on the transmission belt and mold core bodies which are synchronous with the transmission belt and moves along a direction the same as the movement direction of the transmission belt are arranged on the transmission belt. The device provided by the invention has a simple structure and is provided with the mold core bodies which is synchronous with the transmission belt of the traction devices and moves along a direction the same as the movement direction of the transmission belt and synchronous traction of the mold core bodies and traction devices is realized. Therefore, corrosion resistance and pressure resistance of the corrosion-resisting glass fiber-reinforced plastic pipe are improved; quality is very stable; appearance is beautiful; and practical applicability is high.

Description

technical field [0001] The invention relates to equipment for producing corrosion-resistant FRP pipelines, in particular to a production device for corrosion-resistant FRP pipelines. Background technique [0002] Corrosion-resistant FRP pipes in the prior art are produced by intermittent pultrusion production devices, that is, the mold core is fixed through the outer mold. During production, the haul-off machine clamps the solidified pipes and pulls them alternately to achieve the purpose of continuous production. However, this device produces Corrosion resistance FRP pipes have poor corrosion resistance, unstable product quality, and poor practicability. Contents of the invention [0003] The object of the present invention is to provide a novel corrosion-resistant glass steel pipe production device, which has a simple and reasonable structure, high production efficiency and good practicability. [0004] The technical solution to achieve the purpose of the present invent...
