Processing equipment for winding fiber yarn bundle on rectangular pipeline

Abstract

The invention relates to processing equipment for winding a fiber yarn bundle on a rectangular pipeline. The processing equipment comprises a winding machine tool body, a creel and a main shaft bracket, wherein the main shaft bracket is provided with a mold main shaft driven by a main shaft motor, and the mold main shaft is provided with a rectangular pipeline mold; the winding machine tool body is provided with a trolley guide rail, and the trolley guide rail is provided with a trolley driven by a servo motor; the trolley is provided with an impregnation tank and a multi-degree-of-freedom spinning mechanism matched with the rectangular pipeline mold; the multi-degree-of-freedom spinning mechanism comprises two supports arranged on the trolley, and guide rails are arranged on the two supports respectively; each guide rail is provided with a sliding block, and a spinning head is arranged between the two sliding blocks; and the spinning head moves front and back, moves up and down and circumferentially rotates around a fixing shaft through a driving assembly. The processing equipment has the advantages that the winding uniformity and stability of the fiber yarn bundle are guaranteed, the contact friction force between the fiber yarn bundle and the spinning head is avoided, and the consistent stability of the structural strength and mechanical properties of the rectangular pipeline are guaranteed.

Description

Technical field: [0001] The invention belongs to the field of fiber yarn bundle winding rectangular pipes, in particular to a processing equipment for fiber yarn bundle winding rectangular pipes. Background technique: [0002] At present, when processing rectangular pipes, the two components of fiber cloth and resin are mixed, and then hand-made or casted on a mold. The rectangular pipes produced in this way have high cost and low production and processing efficiency; the existing rectangular pipes The current pultrusion technology can only produce rectangular pipes with small cross-sections, and the structural strength is low, so the pultrusion of rectangular pipes has relatively large limitations. The rectangular pipe formed by winding fiber yarn can solve the defects of low mechanical strength, high manufacturing cost, easy deformation of rectangular pipe, and low production efficiency in the production process of ordinary processes. In addition to providing reliable che...

Problems solved by technology

[0003] However, the existing glass fiber bundles are increasingly mature in the winding technology of circular pipes, but there are following defects when winding rectangular pipes: 1. Since the four faces of the rectangular pipes are planes, there is no fiber yarn bundle running on the plane. Tension tangent point, the phenomenon of slits, disordered arrangement, superimposed twisting of fiber yarns in the winding process, which affects the structural strength of the rectangular pipe after forming; Pipe mold winding, the fiber yarn bundle is wound on the rectangular pipe mold with the rotation of the rectangular pipe mold, because the rectangular pipe mold has four planes and four edges, the fiber yarn bundle is at the exit of the spinning head and the rectangular pipe mold The tension on the pipe mold is inconsistent, so that the friction of the fiber yarn at the spinning head is always in a state of change, which accelerates the wear of the fiber yarn. Secondly, the fiber yarn after dipping is affected by friction and tension. The content of glue in different positions is different, and it remains at the spinneret at the same time, polluting the spinneret and the surrounding environment
