Description

A kind of changing reed stroke mechanism of rapier towel loom

Technical field

This utility model is related to textile machine and in particular to Terry Towel Loop-pile Mechanism.

Background technology

The beating device of ordinary loom, is made up of parts such as reed, slay, rocking arm and lay swords, drives beating device What backswing was moved is usually to be realized by conjugate cam or double leval jib or six bar mechanism, and the traverse that beating device swings back and forth is fixing 's.

The fluffing mode of stop mechanism for towel machine is divided into cloth to move and reed moves two ways.Move in napping machine in cloth, the beating of reed is moved Journey is changeless, woven loop be by fell movable realizing, while fell is moved rearwards by, after The parts such as beam, temple, takers-in are moved rearwards by together, and moving component is various, motion is huge, and machine vibration is big, and power is big, And in weaving process warp thread in the harness eye of heald also movement back and forth so that warp thread serious wear, or because friction produces Cracked ends machine halt trouble more or warp thread is had high demands.In changing reed stroke device, it is the beating traverse by changing reed To realize the weaving of looped pile, the device of changing reed stroke is relatively easy, and mechanism is compact, and machine vibration is little, and power is little, and suitable high speed is knitted Make.

In prior art, in reed stroke changing type napping machine, the beating traverse of beating reed is fixed, and does not therefore enable looped pile Height change, the form of towel cloth single it is impossible to meet market diversification require as various in weaved wave hair, embossment hair etc. Property Fabric Style.

Utility model content

Technical problem to be solved in the utility model is exactly to provide a kind of changing reed stroke mechanism of rapier towel loom, solution Certainly the product terry height of existing terry cloth loom is fixed, the technical problem that terry cloth loom weaving speed is slow, weaving vibrating noise is big.

For solving above-mentioned technical problem, this utility model adopts the following technical scheme that：A kind of reed of rapier towel loom moves Fluff mechanism it is characterised in that：Including servomotor, worm-and-wheel gear, hinge linkage and beating device, described beating Device includes hinged rocker arm shaft and rocking arm, and described rocker arm shaft is fixed with fork, and described worm screw is driven by servomotor Move and rotate, described worm gear is arranged on bent axle and does reciprocally swinging by worm drive along crank rotation center, described hinge Chain linkage includes hinged with bent axle and by bent shaft-driven pull bar, the amount of spin of described Serve Motor Control worm screw and worm gear And hinge linkage action is driven so that rocker arm shaft and rocking arm produce relative motion and then adjust fork and rocking arm by pull bar Angle.

Preferably, described hinge linkage also includes hinge, push rod, the first strut, the second strut, and described pull bar is by song Axle drives edge pivot, described push rod is driven by pull bar and does space swing, and described first strut and the second strut are driven by push rod Dynamic space of doing swings.

Preferably, described servomotor is connected on fluffing casing by motor cabinet, and described worm screw leads to many a pair of bearings peaces It is contained on fluffing casing, described bent axle is arranged on fluffing casing by a pair of bearings.

Preferably, described beating device also includes holding fixing shaft coupling and beating of being connected with shaft coupling tightly with rocker arm shaft Latitude axle, lay sword, slay, reed press strip and reed, drive tightening weft axis, lay sword, slay, reed press strip successively by shaft coupling And reed makes oscillating motion and to realize the change of beating traverse.

The technical solution adopted in the utility model, the Serve Motor Control worm and wormwheel of fluff mechanism rotates, and drives pull bar Push rod is promoted to do controlled swing with the rotating shaft of hinge, thus promoting the first strut and the second strut to adjust the folder of fork and rocking arm Angle, makes to rotate pivot angle produced by rocker arm shaft with change when in conjugate cam driven roller and rocking arm, thus by connection Axial organ changes the beating traverse of beating reed, can arbitrarily change beating traverse in certain scope, has simple control and ties Structure, and compact motion, can meet many styles, the diversified demand of towel cloth.

Specific embodiment

As shown in Figures 1 to 4, the changing reed stroke mechanism of a kind of rapier towel loom, including servomotor 1, worm and gear Mechanism, hinge linkage and beating device.Wherein, described beating device includes rocker arm shaft 14 and rocking arm 10, rocker arm shaft 14 with Being provided with a pair of needle bearing between rocking arm 10 to be connected, rocker arm shaft 14 being fixed with fork 11 by screw lock, so so that shaking Arm 10 can produce relative rotation and rocker arm shaft 14 between, can arbitrarily adjust fork 11 and rocking arm 10 in the range of certain angle Angle, different angles required to meet the change of different towel cloth looped piles.Hold tightly on rocker arm shaft 14 and be fixed with shaft coupling 15, Shaft coupling 15 is connected with tightening weft axis 16, lay sword 17, slay 18, reed press strip 19 and reed 20, is carried successively by shaft coupling 15 Dynamic tightening weft axis 16, lay sword 17, slay 18, reed press strip 19 and reed 20 action with realize beat up traverse change, one Beating traverse can arbitrarily be changed in fixed scope.

Described worm-and-wheel gear includes worm gear 4 and the worm screw 3 engaging, and described worm screw 3 is driven to do by servomotor 1 and rotates Motion, described worm gear 4 is fixedly mounted on bent axle 5 by screw and is done toward physical pendulum from the center of rotation of worm screw 3 drives edge bent axle 5 Dynamic, servomotor 1 is connected in fluffing casing (frame) by motor cabinet 2, and worm screw 3 is led to many a pair of bearings and is arranged on fluffing casing On, bent axle 5 is arranged on fluffing casing by a pair of bearings.

Described hinge linkage includes pull bar 6, push rod 7, hinge 8, the first strut 9, fork 11 and the second strut 13.Draw Bar 6 one end, by eccentric being connected on bent axle 5 of bearing, drives hinge linkage thus realizing worm gear 4 and rotating, pull bar 6 is another Outer one end is connected with hinge 8 by bearing with push rod 7 by bearing simultaneously, and hinge 8 is arranged on fluffing casing by bearing, pushes away Bar 7 is connected with the first strut 9 and the second strut 13 by bearing.First strut 9 is connected with rocking arm 10 by bearing, the second strut 13 are connected with fork 11 by bearing.Conjugate cam 21 is installed on fluffing case by bearing, is conjugated convex by main frame power drive Wheel 21, thus driven roller band motion rocker arm, provides power to beating.

As shown in figure 3, pull bar 6, push rod 7, the first strut 9 and the second strut 13 are all the spaces doing fixed track swinging, from And realize to rocking arm 10, the transmission of fork 11 power and kinematic constraint.Rocker arm shaft 14 and rocking arm 10 is made to produce relative motion and enter And adjust fork 11 and the angle of rocking arm 10, to meet the different angles needed for different towel cloth looped pile changes.

As shown in figure 5, worm screw 3 drives worm gear 4 along O1 fulcrum small angle rotation, swing around O2 when pull bar 6 is driven by bent axle 5 Rotate and pind down by hinge 8 and rotate against around O3, hinge 8 is driven by pull bar 6 and rotates around O4, and push rod 7 is driven by pull bar 6 and turns around O3 Dynamic, the first strut 9 is driven and pind down by rocking arm 10 by push rod 7 and rotates around O5, and the second strut 13 is driven by push rod 7 and by fork 11 Pin down and rotate around O6, rocking arm 10 is driven by cam 21 and rotates around O8, and fork 11 is by rocking arm 10 and the first strut 9, the second strut 13 Common driving rotates around O8.

This utility model adopts high sensitivity rotating servomotor to drive, and determines angle rotation by servomotor 1, and essence The true amount of spin controlling worm screw 3 and worm gear 4, then pass through hinge linkage, fork 11 and rocking arm 10 can be accurately controlled Angle, the included angle A making fork 11 and rocking arm 10 from minimum to maximum, thus can achieve fabric looped pile from 0～12mm height from By accurately changing, meet the terry height required for fabric.
