Description

A special rapier loom for wide-angle cloth

technical field

The present invention relates to textile machines, in particular to rapier looms for weaving.

Background technique

The beating-up mechanism and the let-off mechanism of ordinary looms are arranged vertically to each other, and the beating-up method is a swing type beating-up, and the warp and weft of the woven fabric intersect vertically, which is widely used. With the advancement of science and technology and economic development, this commonly used fabric can no longer meet some special needs, and the wide-angle fabric formed by obliquely interlacing warp and weft is more versatile. Due to the strong deformation ability of the wide-angle cloth and the outstanding stretching ability along the vertical direction of the cloth surface, it is used as the wrapping cloth of the tapered missile head and rocket; in the industry, when it is used as the outer wrapping cloth of the conveyor belt, it can improve the reverse flexion of the conveyor belt Fatigue strength, better wear resistance, longer service life. The production method of wide-angle cloth, according to the literature, some ordinary fabrics are cut obliquely along the cloth width, woven into bag fabrics on ordinary looms, and then spirally cut at a certain angle, which is not really wide-angle cloth; There is a magnetic knitting method in which the warp is moved during the weaving process to make wide-angle cloth, which is relatively complicated and not suitable for industrial applications. At present, the production of wide-angle cloth in China is divided into two steps. The first step is to weave the cloth with ordinary warp and weft intersecting at a 90° right angle with an ordinary loom; the second step is to use a tenter device to stretch the warp and weft to form the desired required angle. This method has low production efficiency, narrow cloth width, sparse weft density, large waste and high cost, which limits the production and application of wide-angle cloth.

Contents of the invention

The purpose of the present invention is to provide a wide-angle cloth loom with reasonable structure and convenient operation, which can be selected to intersect at any angle between warp and latitude, which can directly weave high-quality wide-width wide-angle cloth, improve production efficiency, reduce production cost, and meet market demand. Improve economic and social benefits.

Task of the present invention is accomplished like this. Design and manufacture a special rapier loom for wide-angle cloth, which is composed of a warp let-off take-up mechanism, a beating mechanism, a weft insertion mechanism, and a main frame.

The coiling frame is transported in the direction of the coiling frame. The coiling frame is set at the end of the coiling cloth. The servo motor installed in the coiling machine box drives the coiling shaft to rotate. The transmission sprocket at the end of the shaft drives the cloth take-up shaft to rotate, and winds the woven wide-angle cloth into a cloth roll.

In the present invention, because the host frame, the let-off frame and the take-up frame are placed obliquely, a brand-new beating-up mechanism is designed, and the traditional swinging beating-up method is changed to a linear reciprocating beating-up method, so that it can Punch in weft yarns that intersect the warp at any angle. At the same time, the supporting reed is adapted to the weaving of wide-angle cloth, and cooperates with the beating mechanism. The let-off mechanism is responsible for the active unwinding of the warp thread, which is controlled by the let-off servo motor. The horizontal fixed back rest on the let-off frame supports the yarn, and the movable back rest responds to the yarn tension and compensates for the yarn movement. A coiling servo motor is installed in the coiling machine box, which operates under the control of the electrical box. The transmission mechanism drives the coiling shaft to rotate at a constant speed. While the take-up shaft is rotating, the transmission sprocket at the shaft end is connected to the transmission sprocket at the end of the cloth take-up shaft through the transmission chain L, driving the cloth take-up shaft to rotate, and the cloth is rolled up with constant tension. The weft insertion mechanism is composed of a weft insertion chassis, a dial, a fixed guide rail, and a weft insertion guide rail. It is matched with the beating mechanism. During the beating process, the reed teeth of the reed and the warp are kept parallel and do not interfere. The conjugate cam mandrel is set in the beating box and the conjugate cam is in contact with the rollers at both ends of the small swing arm to drive the small swing arm to swing back and forth, driving the swing arm and the connecting rod to move. The main drive shaft of the main engine frame rotates at a constant speed driven by the main motor, and the bevel gear of the main shaft meshes with the bevel gear at the end of the conjugate cam spindle of the beating mechanism to drive the conjugate cam spindle to rotate, driving the conjugate cam to push the small swing arm The reciprocating pendulum drives the rocker arm to drive the connecting rod to reciprocate, and the connecting rod drives the slide to reciprocate along the linear guide rail.
