Description
Technical field
The utility model relates to the doup edge device of a kind of Rapier looms, particularly a kind of Rapier looms, belongs to textile machine.
Background technology
The tradition leon-selvedge mechanism has two kinds of machine driving and electronics transmissions, and mechanical leon-selvedge mechanism generally is by the plain weave motion up and down of cam driven strand side rod, realizes two yarn doup edges by special-purpose leno edge machine, and heald level time changes by mechanical adjustment.As disclosing a kind of doup edge Geneva mechanism among the Chinese patent CN02220235.8, constituted by main shaft, sheave, roller, fork, connecting rod, slide bar and tensioner circle, sheave is enclosed within on the main shaft, fastening with tensioner circle and screw location, roller is embedded in the groove of sheave, fork is the T word shape, be movably connected on the fulcrum, the T type lower end of fork and roller flexibly connect, the T type both upper ends thereof of fork flexibly connects with two isostructural connecting rod one ends respectively, and the other end of two connecting rods flexibly connects with the plush copper of two slide bars respectively.This doup edge Geneva mechanism drives the sheave rotation by main shaft, drive fork when roller in the sheave rolls and swing by being arranged on again, driving two slide bars at last slidably reciprocates up and down, in real work, situation stuck or the rotation underaction appears in the roller of this sheave structure easily.The electronics transmission is that the reciprocating motion by stepper motor makes the strand side rod do plain weave motion up and down, realize two yarn doup edges by special-purpose leno edge machine then, but heald level time electronic settings, yet reciprocating motion exists and to require high, frequent starting braking to make that the loss of electric machine is big, connecting rod place bearing is hit shortcomings such as power is big to motor, and reliability is undesirable.Other two yarn leno-fastening tissues easily produce selvedge faults such as limit looped weft, selvedge lock is not tight to some fabrics.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of simple and reasonable, cost of manufacture is low, flexible operation, the motion of strand limit are reliable, heald level time set easy to adjust, adapt at a high speed, selvedge locking firmly, the yarn ribbed border device of the Rapier looms of long service life, to overcome weak point of the prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of doup edge device of Rapier looms, comprise the motor that is arranged on the support, its architectural feature is that motor is hinged by eccentric disc and push rod one end, the push rod other end and fork middle part are hinged, the fork middle part is hinged on the support, and fork one end is provided with yarn guiding ring and last yarn bar, and last yarn boom end is provided with the hole of entrying, the fork other end and connecting rod one end are hinged, and the connecting rod other end and forward and backward yarn bar are hinged; Motor is hinged by eccentrically weighted shaft and forward and backward yarn bar, and forward and backward yarn bar is provided with down the hole of entrying, and forward and backward yarn bar is arranged on the fork side.
Above-mentioned support is provided with fixed arm, and fixed arm and fork middle part one side are hinged, and push rod and fork middle part opposite side are hinged.
Above-mentioned eccentrically weighted shaft is provided with eccentric step, and preceding yarn bar and back yarn bar are separately positioned on the eccentric step.
Above-mentioned eccentric step is the eccentric step of pre-eccentric step and back, and the eccentric step of pre-eccentric step and back is symmetrical arranged; The eccentric rotating disk of pre-eccentric rotating disk and back is located on the eccentric step of pre-eccentric step and back by bearing holder (housing, cover) respectively, and preceding yarn bar and back yarn bar join with the eccentric rotating disk of pre-eccentric rotating disk and back respectively.
Protect preceding yarn bar and back yarn bar synchronous operation in order really to be provided with, its middle part is coated with the axis of guide simultaneously, axis of guide side compression spring.
Strand of the present utility model limit and slitter edge all adopt three skein limit mechanisms; Run duration, motor runs up towards a direction, need not reciprocating operation, and its operating efficiency is greatly improved.
Through the three yarn lace stitches that the utility model makes, natural selvedge is locked tightlyer, and the slitter edge yarn also forms three yarn lace stitches simultaneously, and its selvedge fault significantly reduces, and has also reduced the quantity of slitter edge yarn simultaneously, saves the slitter edge yarn.
Driven by motor eccentric disc rotation in the utility model, and promote fork by push rod and swing around fixed pin shaft, fork drives upward, and the yarn bar swings up and down, the yarn bar moved back and forth with yarn bar work front and back, back before motor ordered about the eccentrically weighted shaft drive, meanwhile, yarn bar and back yarn bar were done and are swung up and down before fork also drove by connecting rod, so preceding yarn bar and back yarn bar are made compound motion under acting in eccentrically weighted shaft and fork.Wherein, fork whenever rotates a circle and forms a reciprocally swinging, and the operating frequency of swing can adapt to the high speed Rapier looms and use.
The utility model can and be regulated heald level time by program setting, operate easylier, and the rotation mode of stepper motor improves its reliability greatly, adapts to high speed.
The utility model is simple and reasonable, cost of manufacture is low, the motion of flexible operation, strand limit is reliable, heald level time set easy to adjust, adapt at a high speed, selvedge locking firmly, long service life.
