Abstract
The invention discloses a pneumatic and mechanical hybrid tuck-in selvage mechanism. The pneumatic and mechanical hybrid tuck-in selvage mechanism is characterized by comprising a mechanical part and a pneumatic part. For the mechanical part, power is transferred by a weaving machine to a transmission shaft through a synchronous belt and a drive gear to drive a cam set to rotate, a conjugate cam drives a nozzle part and a crochet hook to move front and back through a roller stand and a hollow shaft, and a central cam controls the crochet hook to enter into a cloth-fell timely through a roller swing arm and a swing shaft and the like. For the pneumatic part, after the weaving machine carries out wefting insertion, an electromagnetic valve moves, and a yarn end is blown into a yarn end holding hole by the nozzle. When the yarn end is opened for next wefting insertion, the crochet hook enters into the cloth-fell at the same time. When the crochet hook hole enters into the opening of the nozzle part to move right below the yarn end holding hole, the electromagnetic valve moves, the nozzle blows the yarn end into the crochet hook hole, and then the crochet hook carries the yarn end to move backward to hook the yarn end into the cloth-fell to accomplish edgefold for one time. The pneumatic and mechanical hybrid tuck-in selvage mechanism provided by the invention is stable and reliable in tuck-in selvage, neat and attractive in selvage, is suitable for an air jet loom to weave and can realize an ideal weaving effect.
Description
Technical field
The present invention relates to the selvedge invagination mechanism that a kind of loom uses.
Background technology
Selvedge of the prior art folds into mechanism and comprises mechanical type tuck-in selvage mechanism and pneumatic type tuck-in selvage mechanism, and the characteristics of above-mentioned two types of tuck-in selvage mechanisms and the problem of existence are mainly following:
Mechanical type tuck-in selvage mechanism wherein, it folds into fell by crochet hook with the yarn end merely just through mechanical movement, because the restriction of mechanical structure makes the invagination process unstable, appearance is leaked to discount and resembled easily, and is particularly more unstable when high-speed cruising.Therefore can only on Rapier looms, use at present; In addition because the hooklet shape can only be made in the working position of the crochet hook of mechanical type tuck-in selvage mechanism; Be exactly to open wide on one side, guarantee to hook the yarn end, this just easy hook cracked ends yarn; Influenced the weaving efficiency of loom widely, this also is the reason that pure mechanical tuck-in selvage mechanism is difficult to apply.
Pneumatic type tuck-in selvage mechanism wherein, it be through electromagnetic valve at preset time, in sequence to the several nozzle air feed on the hemmer, pneumatically is blown into fell with the yarn end and forms selvedge.Pneumatic type tuck-in selvage mechanism adapts at a high speed weaves; But because air-flow is difficult to accurately control; The flanging effect is attractive in appearance not as the machinery invagination; Pneumatic in addition flanging will occur folding into bad phenomenon for the yarn that is not easy to bend, but that is to say that the woven fabric scope of pneumatic type tuck-in selvage mechanism is narrower owing to be to lean on air-flow to accomplish the yarn end to fold into; The pneumatic type tuck-in selvage mechanism that uses at present besides, the reed that is positioned at the nozzle place need block, the raising that this meeting brings certain trouble and weaves cost to the user.
This shows that above-mentioned tuck-in selvage mechanism awaits further to improve.
Summary of the invention
