Glass fiber reinforced plastic pipeline winding system and method

Abstract

The invention provides a glass fiber reinforced plastic pipeline winding system. The system comprises two symmetrically arranged glass fiber reinforced plastic winding units and a demoulding unit arranged between two glass fiber reinforced plastic winding units. Each glass fiber reinforced plastic winding unit comprises a plurality of winding shafts. Each winding shaft is provided with three symmetrically arranged core shafts. The diameters of all core shafts are same and less than 150 mm. The provided system can manufacture a plurality of glass fiber reinforced plastic pipelines simultaneously. According to the provided winding method, for the glass fiber reinforced plastic pipelines with an internal diameter not more than 350 mm, corresponding pipeline moulds sleeve on each core shaft, one end of the plastic pipelines is winded by an mechanical arm; for the glass fiber reinforced plastic pipelines with an internal diameter in a range of 400 mm to 600 mm, corresponding pipeline moulds sleeve on two neighbored core shafts, one end of the plastic pipelines is winded by an mechanical arm; and for the glass fiber reinforced plastic pipelines with an internal diameter not less than 700 mm, pipeline moulds sleeve on three neighbored core shafts, and two ends of the plastic pipelines are winded by mechanical arms; the consumed time is not more than that of manufacturing glass fiber reinforced plastic pipelines with a small internal diameter; and the production speed and efficiency are improved.

Description

technical field [0001] The invention relates to the field of FRP pipe manufacturing, in particular to a FRP pipe winding system and method. Background technique [0002] FRP pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. It is formed by winding glass fiber with resin matrix weight on the rotating mandrel layer by layer according to the process requirements, and spreading quartz sand evenly over a long distance between the fibers as a sand layer. The existing FRP pipe manufacturing process is to continuously wind the glass fiber with a machine on the pipe mold, and finally solidify and form it. [0003] In order to improve the production efficiency of FRP pipes, Chinese patent 200420019112.3 (publication number: CN2724981Y, publication date: September 14, 2005) discloses a driving type multi-core module FRP pipe winding machine, which performs The improvement is made, the two ends of the track beam of the driving trolley are respectively set on...

Problems solved by technology

[0004] However, the structure provided by the above-mentioned patent only refines the equipment of the winding machine. Obviously, when the caliber of the FRP pipe to be manufactured changes, the specifications of the mandrel need to be replaced, which causes a lot of inconvenience.
