Continuous winding machining technology of bamboo wound composite tube

Abstract

The invention relates to continuous winding machining technology of a bamboo wound composite tube. A circulating steel strip is wound outside a hollow steel die; the rotation of the steel die drives the steel strip to advance helically; gum-containing non-woven fabric is wound on the surface of the steel strip layer by layer through a lining manufacturing zone feeding device, so that a lining layer is manufactured; the helical advancing of the steel strip drives the lining layer above to rotate and advance; the heated and initially cured lining layer is separated from the steel die from the tail end of the steel die; the steel strip outside the steel die returns to the head end of the steel die through the axial cavity of the steel die, so that lining layers are continuously prepared again; meanwhile the initially cured lining layer advances continuously; bamboo skin fabric is wound outside the lining layer through a plurality of winding zone feeding devices till designed thickness is achieved; with the continuous circulation of the steel strip, tubes wound by the bamboo skin fabric advance continuously; the tubes are cured, polished and finished, and then are subjected to cutting and segmentation; outer protective layers are painted on the tubes; ports of the tubes are machined, so that the tubes can be connected in a sealed way. The technology is efficient in production and stable in quality.

Description

Technical field [0001] The invention relates to a production process of a bamboo composite pressure pipe, in particular to a continuous winding processing process of a bamboo winding composite pipe. Background technique [0002] At present, the main process used to produce bamboo composite pressure pipe is the fixed-length winding process, that is, the pipe mold with a certain pipe diameter and length is used to reciprocate, the feeding device is fixed, and the spiral winding or hoop winding process is used on the pipe mold from the inside to the outside. A processing method to make the inner lining, reinforcement layer and outer protective layer of bamboo composite pipe layer by layer. The patent number is 200910099279.2 and the Chinese patent titled "Method for preparing bamboo fiber wound composite pipe" discloses a method for preparing bamboo fiber wound composite pipe. The preparation method includes the following steps: 1) Preparation of inner lining: Use resin and felt to...
