Bottom warp feeding tension balance regulating mechanism for towel rapier loom

Abstract

The invention relates the towel gripper loom ground warp and run-in warp tension balance controlling mechanism, comprising back rail pin, back bar conjunction, ranging arm conjunction, stretch roll conjunction installed on ranging arm conjunction by axle bearing, balance bar fixed on back bar conjunction, counterbalancing mass on the back end of balance bar. The lower end of tension balance bar is fixed on wall plate, and the tension balance bar comprises adjustment hand-wheel, compression spring, spring positioning disk and counterbalancing mass, and the adjustment hand-wheel is connected with tension balance bar by thread. The mechanism has the following advantages: 1 reducing cutting end; 2 reducing friction and reducing broken ends; 3 making the tension on loom stable.

Description

Technical field: [0001] The invention relates to a towel rapier loom, in particular to a bottom warp let-off tension balance adjustment mechanism of the towel rapier loom. Background technique: [0002] The towel rapier loom is a special production equipment for towel factories in the textile industry. Among the existing towel rapier looms, the bottom warp let-off tension balance adjustment mechanism of the towel rapier loom has the following two typical structures: [0003] ① Use the weaving back beam and rear rod (small bending shaft) plus a counterweight, and adjust the let-off tension of the bottom warp yarn by changing the front and rear positions of the counterweight. The tension must be adjusted manually according to the tension of the fabric surface. The adjustment precision of the tension adjustment mechanism is not high, the stability of the warp tension is poor, and the yarn breakage rate is high. This type of towel rapier loom is represented by the 74 series. ...

[0003] ① Use the weaving back beam and rear rod (small bending shaft) plus a counterweight, and adjust the let-off tension of the bottom warp yarn by changing the front and rear positions of the counterweight. The tension must be adjusted manually according to the tension of the fabric surface. The adjustment accuracy of the tension adjustment mechanism is not high, the stability of the warp tension is poor, and the end-break rate is high

[0004] ② Continue to use the tension balance mechanism of the GA615B shuttle towel loom, which is difficult to adjust the tension
