Problems solved by technology

[0003] With this set of production equipment, it is not only necessary to move the mold around the site of use, which greatly increases the cost of manpower and material resources, and reduces the production efficiency, but also squeezes the thermosetting resin impregnated on the fiber due to axial force during winding, In this way, the excess thermosetting resin is squeezed out and the reuse rate of the resin is low, resulting in waste.
On the other hand, the heating and melting process requires hoisting the entire mold wrapped with fiber-impregnated thermosetting resin, and then transferring it to a heating furnace for curing. The equipment used in the production process is allocated independently, and the production process is a discontinuous operation, which cannot be realized. Continuous production
On the other hand, during the production process of fiber-reinforced thermosetting plastic pipes, the water content of the thermosetting resin is uncontrollable, so the curing effect is not good, and loose threads are prone to appear. If the pipe is made into a cable protection tube, it is easy to cause the cable to be stuck.

Abstract

The invention provides a continuous densification and efficient production line and technology of fiber-reinforced thermosetting plastic pipelines, and belongs to the field of fiber-reinforced thermosetting plastic pipeline manufacturing. After being innovatively improved, a paper tube machine production line is applied to the production field of the fiber-reinforced thermosetting plastic pipelines, the improved paper tube machine production line is sequentially provided with strip frames, a coating device, a curing agent applying device, hollow partition plates and a spiral paper tube machine refit device in the paper tube moving direction. Cylindrical dies transversely arranged above a rack are improved on the basis of an existing spiral paper tube machine, pressure perpendicular to the die direction and thrusting force parallel to the die direction are exerted on film strips wrapping the dies and impregnated and pre-cured fiber strips through a conveying belt, layer-by-layer densification and continuous efficient production are achieved, and the production efficiency is greatly improved. The produced pipelines have the beneficial effects of resisting pressure, being good in impact resistance and rigidity, resisting to corrosion and the like.

Description

technical field [0001] The invention relates to the technical field of manufacturing fiber-reinforced thermosetting plastic pipes, in particular to a continuous compaction and high-efficiency production line and process for fiber-reinforced thermosetting plastic pipes. Background technique [0002] Fiber-reinforced thermosetting plastic pipes are widely used in petrochemical, electric power, municipal renovation and other fields due to their excellent corrosion resistance and excellent mechanical properties. The pipe body of fiber-reinforced thermosetting plastic pipe is wound by several layers of fibers impregnated with thermosetting resin. During production, the multi-layer fibers are impregnated with thermosetting resin and then wound on the outer surface of the mold, heated, melted and solidified. The mold is in the shape of a circular tube, and the number of layers of fiber-impregnated thermosetting resin depends on the thickness of the processed tube. At present, the ...
