Abstract

The utility model relates to a true selvedge non-waste-selvedge device for rapier looms, which is characterized in that the left side of a reed is provided with a weft yarn clamp and a suction nozzle; a weft yarn beating rod is arranged on a sley; a connection rod is pressed on the weft yarn clamp and is fixed to the loom by a holder foot; the other end of the connection rod is clearance fit with a rotor and is controlled by a cam; the suction nozzle is connected with the weft accumulator of an exhaust blower by a suction pipe. The right side of the reed is also provided with a weft yarn clamp, a holder foot, a connection rod, a rotor, the control mechanism of a cam, and a suction nozzle is fixedly arranged on the sley at the right side; an air blowing nozzle is arranged at the position which is opposite to the suction nozzle; the suction nozzle is connected with the weft accumulator by a suction pipe. The utility model has the advantages of simple structure, convenient installation, no waste selvedge use, saves weft yarn, has no influence on the performance of the original machine, and is an ideal auxiliary device for the rapier looms.

Description

Rapier looms plain edge slitter edge free device

The utility model relates to a kind of shuttleless loom slitter edge free device, is a kind of Rapier looms plain edge slitter edge free device.

At present, Rapier looms is in weaving process both at home and abroad, can not reciprocating motion because of weft yarn, the cloth both sides that weave are burr, in order to eliminate burr, the tuck-in selvage machine is installed in the loom left and right sides, use two slitter edges in the reed both sides, general every side slitter edge warp is the 16--20 root, in the process of weaving cotton cloth, slitter edge warp and the weft yarn formation slitter edge that interweaves causes very big waste.

The purpose of this utility model provides a kind of Rapier looms slitter edge free device, and Rapier looms also can normally be weaved without left and right sides slitter edge, and guarantees to reduce the weft yarn consumption by fabric quality, to solve slitter edge waste problem.

The purpose of this utility model is achieved in that at former Rapier looms be by reed, slay, right sword head, upper shaft, the tuck-in selvage machine is formed constant, in the reed left side weft clamp is installed, a weft yarn suction nozzle, suction nozzle is connected by suction pipe and weft accumulator, be connected to air exhauster on the weft accumulator, press on the weft clamp and touched connecting rod, the activity of the connecting rod other end is combined with rotor, connecting rod is fixed on the loom by stand-off, by being fixed on the cam control on the upper shaft, on the slay of left side, the bar that beats up is installed, weft clamp of same installation on the reed right side, one cover stand-off, connecting rod, rotor, cam control gear, intrinsic suction nozzle on the slay of right side, suction nozzle is connected on the weft accumulator by suction pipe, is provided with blowing nozzle on the suction nozzle opposite.

Operation principle: after weft yarn is introduced into fell, right sword head discharges weft yarn, owing to be subjected to the power of blowing of blow gun and the suction of suction nozzle, weft yarn is sucked and is squeezed into by suction nozzle in the right suction nozzle slit, slay beats up forward then, this moment, left and right sides weft clamp opened, after entering jaw, clamps weft yarn weft yarn rapidly, slay retreats, and the limit yarn pincers of tuck-in selvage device and scissors are cut off weft yarn at distance selvedge 15mm place forward, finish the weft yarn tuck-in selvage by crochet hook, this moment, the weft yarn tail cut off still by left and right sides weft clamp clamping, and two weft clamps open when treating that reed is broken second weft yarn, and the weft yarn tail is sucked in the weft accumulator by suction nozzle.

This utility model compared with prior art has the following advantages: 1) without slitter edge and can reduce weft yarn, every loom can save yarn more than 150 kilograms every year; 2) cooperate rationally with former machine, do not influence former machine performance; 3) the weft accumulator volume is big, and weft yarn reclaims convenient, and operator's labour intensity is low; 4) simple in structure, easy for installation, be convenient to promote.
