Description

Rapier looms slitter edge free device

The utility model relates to a kind of shuttleless loom slitter edge free device, is a kind of Rapier looms leno-fastening 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 weave burr, the leno-fastening device is installed in the loom both 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 leno-fastening slitter edge free device, and Rapier looms also can normally be weaved without left and right sides slitter edge, and guarantees that fabric quality reduces the weft yarn consumption, 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 leno-fastening device, air exhauster is formed constant, left and right sides temple stand-off is installed respectively in the reed left and right sides, lean on the intrinsic movable stand-off of eccentric nut on the stand-off, intrinsic two horizontal depression bars on the movable stand-off, the perverse ring of the temple that has two connectors to be connected with shortening above, its tail and temple stand-off are apart from 10--20mm, on the left side bracketing pin right side is provided with the left scissors of lengthening, with the leno-fastening device, the left side is provided with suction nozzle and weft clamp, suction nozzle is linked to each other with air exhauster with weft accumulator by suction pipe, press on the weft clamp and touched connecting rod, pass through connecting rod by the cam on the upper shaft, rotor control, connecting rod is fixed on the loom by stand-off, on the slay of left side, be provided with the bar that beats up, bracketing pin right side is provided with suction nozzle and weft clamp and the cam identical with the left side on the right, rotor, the connecting rod controlling organization, there is the right scissors and the leno-fastening device of lengthening in bracketing pin left side on the right, intrinsic suction nozzle on the reed of right side, there is 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 by suction nozzle, and be squeezed in the right suction nozzle slit, slay beats up forward then, this moment, left and right sides weft clamp opened, clamp weft yarn after weft yarn enters jaw rapidly, slay retreats, and weft clamp opens when treating that reed is broken second weft yarn, the yarn tail is promptly sucked in the weft accumulator by suction nozzle, this moment, left and right sides scissors will be cut off apart from the weft yarn of fell 4--5 root yarn apart from selvedge 3--5mm under the drive of upper shaft cam, the work of leno-fastening device.

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 the weft yarn tail reclaims convenient, and labor intensity of operating staff is low; 4) simple in structure, easy for installation, be convenient to promote.
