Description

Glass loom strand is knitted cam shedding mechanism

Technical field

The utility model relates to weaving and uses Rapier looms, is specifically related to the harness motion mechanism of Rapier looms.

Background technology

Domestic glass fibre loom, major part commonly used are shuttle loom and low-grade low speed Rapier looms at present, and fabric quality is difficult to improve, and production efficiency is lower.And import loom price is very high, and users are difficult to bear.YJ-1 type flexible rapier loom is a homemade medium-to-high grade loom of digesting and assimilating imported technology, but still be blank aspect the weaving glass fiber fabric, the dobby shedding apparatus structure complexity that is adopted, volume is big, weight is big, price is high, can not exchange with dobbies, can not be general with other attaching parts, use maintenance cost higher.

Summary of the invention

The purpose of this utility model just provides the shedding mechanism of a kind of glass fabric Rapier looms special use, satisfies the main frame matching performance, and versatility is good, reduces cost of use, enhances productivity.

Task of the present utility model is finished like this: design a kind of glass loom strand and knit cam shedding mechanism, be fixed on above the outer end of base of glass loom, supporting with the glass loom, power transmission shaft, camshaft; the rocking arm axis is set with bearing and is installed in the casing; power transmission shaft installing transmission gear wheel forms a pair of gear pair engaged transmission with the drive pinion that camshaft is installed; suit cam on the camshaft; keep in touch with the rocking arm of installing on the rocking arm axis; the power transmission shaft back segment stretches out in the rear box that casing connects later; the conelet gear with curved teeth engaged transmission on suit auger gear with curved teeth and the line shaft turns to, power transmission shaft and line shaft are installed in respectively in the bearing on the rear box.Rocking arm is " J " shape flat board, turning perforate suit rocking arm axis, and the upper end connects connecting rod by bearing pin, and installing roller in lower end is positioned at below the cam, and the periphery of roller and cam gabarit keep in touch.Rocking arm top is provided with the extension spring frame, is connected tension by extension spring with extension spring frame on the glass loom base.Rocking arm and cam are some to installing corresponding matching arranged side by side.Power transmission shaft and camshaft also are equipped with a pair of synchromesh gear pair, driving gear is sleeved on the power transmission shaft, the end face bolted of driven gear and adjacent cams, and the suit needle bearing is installed on the camshaft together, by the driving gear engaged transmission, rotate synchronously with power transmission shaft.Connecting rod one end of loom is connected with rocking arm, the other end connects the driving rocking arm, and by driving the drive rod that the rocking arm lower end connects loom, the far-end of drive rod connects far-end and drives rocking arm, like this, when connecting rod under cam and rocking arm drive during reciprocating motion, pulling drives rocking arm and rotates around driving rocker arm shaft, drive the push-and-pull of pull bar along continuous straight runs, drive far-end and drive the rocking arm swing, the heald frame that drives rocking arm connection drive rod drive loom moves up and down, and realizes the action of loom opening, can be used for twisting the desmachyme of knitting and weaves.Drive rocking arm, connecting rod, pull bar all can be general with common type.During the strand woven fabric, more former dobby shedding device is raised the efficiency one times.Line shaft is by conelet gear with curved teeth and the engagement of power transmission shaft auger gear with curved teeth, realize transmission turning, power transmission shaft drives camshaft by transmission gear wheel engaged transmission pinion, gear ratio is 2: 1, power transmission shaft whenever rotates a circle and makes camshaft rotate for two weeks, driving gear on the power transmission shaft then drives driven gear on the camshaft and fixedly connected cam and power transmission shaft and rotates a week synchronously, matches with heald frame behind the loom specially.Rocking arm is held by extension spring and is made roller be close to the cam gabarit, promote the rocking arm swing by roller during the cam rotation, the rocking arm drivening rod moves back and forth, and then drives the swing of driving rocking arm, cylinder lever connecting rod drives far-end driving rocking arm and swings in the same way, realizes the reciprocating action that shedding mechanism needs jointly.

Design and produce, test according to above-mentioned, prove that the utility model and main frame matching performance are good, can be general with the opening features of loom, to compare with original dobby shedding mechanism, cost is low, expense is few, efficient is high, has reached predeterminated target preferably.
