Special-shaped tube for looms and application thereof to water-jet or air-jet looms

Abstract

The invention discloses a special-shaped tube for looms. The special-shaped tube for the looms comprises a seamless steel tube body, a left connecting flange and a right connecting flange, wherein thecross section of the seamless steel tube body is in a special polygonal shape, the left connecting flange and the right connecting flange are fixedly welded on the left and the right of the seamlesssteel tube body respectively and provided with bolt mounting holes, and a sealed space is formed between the left and right connecting flanges and the cavity of the seamless steel tube body. The invention discloses the special-shaped tube for the looms and application thereof to water-jet or air-jet looms; when mounted onto an existing water-jet or air-jet loom, the special-shaped tube for the looms can improve the stability of the overall frame of the loom, reduce wearing of the parts of the loom and improve the production efficiency of the loom.

Description

technical field [0001] The invention relates to the field of loom mechanical equipment, in particular to a special-shaped pipe for a loom and its application on a water-jet or air-jet loom. Background technique [0002] A loom is a machine used to interweave two or more groups of yarns at right angles to form a fabric. It is classified into a loom and a brocade machine; it can be divided into two categories: a shuttle loom and a shuttleless loom according to the weft insertion method of weaving. ; Among them, water jet loom and air jet loom are two important models of shuttleless loom. The air-jet loom uses the jetted compressed air to pull the weft yarn and bring the weft yarn through the shed. The biggest feature of the air-jet loom is its fast speed and high labor productivity. It is suitable for plain and textured fabrics, fine and high-density fabrics and large-batch fabrics production. The water-jet loom uses water as the weft insertion medium to generate friction an...

Problems solved by technology

At present, whether it is a water jet loom or an air jet loom, a frame frame consisting of a front upper beam, a front lower beam, a rear upper beam and a rear lower beam is used, but these front upper beams, front lower beams, and rear upper beams Or the rear lower beam generally adopts square steel pipes of common specifications. Due to the high-speed operation of the loom, the overall equipment of the loom is severely worn and the production efficiency is low.
