Abstract

The invention discloses a cladding device used for multilayer composite braided fiber ringlike bands. The device comprises a rack, a cladding die, a tensioning and hauling bracket, torpedo-head spreaders and a pair of hauling and conveying rollers, wherein the cladding die is fixed to the rack, the tensioning and hauling bracket faces directly the cladding die and is slidably arranged on the rack; the torpedo-head spreaders are arranged on the tensioning and hauling bracket and separate the multilayer composite braided fiber ringlike bands; hauling and conveying rollers are connected to the tensioning and hauling bracket through shafts and drive the separated multilayer composite braided fiber ringlike bands to penetrate through the cladding die. By means of the device, the multilayer composite braided fiber ringlike bands are evenly coated with polyurethane internally and externally through the die, and a high pressure resistant polyurethane water band pipe which is smooth and flat in internal surface and external surface is produced out.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a covering device for a multi-layer composite braided fiber endless belt. Background technique [0002] At present, the traditional method of producing polyurethane high-pressure annular braided pipe by covering the multi-layer composite braided fiber annular belt has many defects. For example: the inner and outer polyurethane coating is uneven, the surface is not smooth and dense, there are wrinkles, and the product thickness adjustment function is not available due to unreasonable structural design. Therefore, designing a set of reasonable and effective coating devices to solve the above defects is a research direction for those skilled in the art. Contents of the invention [0003] The purpose of the present invention is to provide a coating device, which uniformly coats polyurethane on the inside and outside of the multi-layer composite braided fiber annular belt through a mold, s...
