Abstract
The invention relates to a method and a device for continuously winding a molded tube in a multi-head wet process. According to the invention, a continuous composite tube penetrates through a central tube of a rotating winding machine to do rectilinear motion, and fibers hung on the rotating winding machine rotate with the rotating winding machine. The winding process comprises the steps of (a) fiber bundling, wherein the fibers are gathered through a yarn combining ring and are uniformly distributed along the circumference; (b) fiber gluing, wherein the fibers are uniformly distributed at the periphery of a cage-shaped roller, and when the cage-shaped roller rotates, the fibers gradually enter a glue groove to be soaked into resin glue; (c) fiber glue extruding, wherein redundant resin glue of the glued fibers is extruded through a glue extruding ring until the fibers are completely infiltrated by the resin glue; (d) fiber winding, wherein the uniformly and completely glued fibers wind the continuous tube through a spiral mold capable of effectively controlling the winding angles, widths, thicknesses, number and gaps; (e) curing forming, wherein after each winding layer is completed, the continuous tube is subjected to curing forming for 40-60 minutes at 60-80 DEG C. The device is reasonable in design and simple in structure and is capable of adjusting the proportion of the resin and the fibers at any time, controlling and adjusting the winding angles, widths, thicknesses, number and gaps of yarn belts and guaranteeing the structural strength and mechanical property of the winding layers on the composite tube.
