Ultrahigh-speed shuttleless narrow loom

Abstract

The invention relates to the technical field of weaving, in particular to an ultrahigh-speed shuttleless narrow loom, and solves the problems of an incomplete part structure, large assembly and maintenance amount, low weaving accuracy and a low weaving speed of the conventional ribbon loom. The loom comprises a frame, a driving device arranged in the frame, and a weaving mechanism, wherein the weaving mechanism comprises a weft insertion mechanism, a heald frame mechanism, a pattern chain and a rocker arm; the weft insertion mechanism has an integral base split clamping structure; a tensioning pressure seam is arranged at a position where a weft insertion bearing is arranged and positioned; the two ends of an inner ring of the weft insertion bearing stretch out of an outer ring to be manufactured into a weft insertion small shaft; the heald frame mechanism is provided with a bearing seat frame and a clamping transverse heald frame which are vertically sleeved with each other; the bearing seat frame is provided with a plurality of linear bearings which correspond to one another coaxially up and down; an elastic steel wire heald with a heald eye is arranged in the clamping transverse heald frame; and the pattern chain is formed by connecting a double high pattern sheet, high and low chain sheets and a double low pattern sheet through tenon sheets and notches. The ultrahigh-speed shuttleless narrow loom has high weaving accuracy and a high weaving speed and is convenient to assemble and maintain.

Description

technical field [0001] The invention relates to the technical field of weaving, in particular to an ultra-high-speed shuttleless narrow-width loom with stability and high precision and a weaving speed exceeding 2000 times per minute. Background technique [0002] Most of the existing ribbon looms have defects in the structure and component manufacturing process of each component, and the weaving speed is difficult to exceed 1500 times per minute, that is, one weaving can complete the warp let-off, heald lifting, weft hooking, reeding, and so on. The speed of the main six actions such as coiling, the outstanding defects are as follows: [0003] 1. The structure of the heald lifting parts is far-fetched and simple, and the precision and strength are poor, the wear is large, the deviation of the heald lifting reaches millimeter level, the failure rate is high, and the maintenance is inconvenient. [0004] 2. The weft-injection shaft, bearing, and bearing seat in the weft-injec...

AI Technical Summary

Problems solved by technology

[0010] The purpose of the present invention is to solve the problems of the existing ribbon looms, such as imperfect structure of components, large amount of assembly and maintenance, high power consumption, poor weaving precision, and low weaving speed, and to provide an ultra-high-speed shuttleless narrow-width loom. The design is reasonable, the weft insertion mechanism adopts the integral base, the high-precision weft insertion bearing with the small weft insertion axis formed by the inner ring of the bearing, the heald frame mechanism with linear bearings, and the clamping horizontal heald beam achieves high weaving accuracy , High weaving speed, good stability, easy assembly and maintenance
