Description
Technical field
The invention belongs to parts of textile machine, be specifically related to the governor motion of the woven stitch density tightness that uses on a kind of knitting machine.
Background technology
In Full-automatic computerized flat, the adjusting of the tightness of sweater loop construction is to realize by the difference of head density triangular to the knitting needle presser feet degree of depth at present.Its control mode has mechanical type or step motor control formula etc., and its version is different.At present, the close structure of accent that Computerized flat knitting machine is commonly used mainly contains two kinds, a kind ofly transfers close mechanism for the open type cam, and another kind is that closed cam is transferred close mechanism.Open cam transfers close mechanism structure simple, and part processing is easy with the adjustment of density, but density triangular by driving lever toward the process that presses down in, owing to the rigidity of driving lever, up resilience.Knitting needle is in the braiding process, because some needle plate slot has incrustation, make the knitting needle in the respective grooves in motion process, produce play, therefore, knitting needle can be lower than a bit of distance of pressing working face, faster in braiding speed, more obvious in the larger situation of bodkin kind resistance, broken hole, broken end that causes the fracture of wool yarn and fabric etc. sheltered disease.Closed cam is transferred close mechanism structure form more complicated, roll in the chute of bearing in cam, the driving lever action is relatively stable reliable, because bearing is in driving lever and the formed draw-in groove of depression bar, knitting needle is in the braiding process, same some needle plate slot has incrustation, make the knitting needle in the respective grooves in motion process, produce play, therefore can produce moment active force up to density triangular, when depression bar can rotate around bearing pin, force transmission is having on the spring of damping performance, eliminated impact, thereby density triangular just eliminated to pin heel moment pressure down, therefore the Density of braiding is relatively even, stable, reliably, the adjustment of density zero-bit is easy, and assembly precision is high.But can't control the fabric that has height pin bell to realize, can not realize the adjustment to accurate coil.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned deficiency, a kind of governor motion of woven stitch density tightness is provided, this governor motion is with the more double-deck density triangular of head density of single layer triangle, realized the control to the knitting needle high and low position, adjustable range is wide, precision is high, and the sweater fabric that knits out has stereoeffect.
Technical scheme of the present invention: a kind of governor motion of woven stitch density tightness, it comprises the first motor, the first end face cam, clutch shaft bearing, driving lever, the variable density triangle, T shape slide block, eccentric ratio, pole, the second bearing, the second edge cam, the second motor, V-arrangement pole and slide block, the first end face cam is arranged on the output shaft of the first motor, clutch shaft bearing is arranged on the driving lever, and be connected with the rolling of first end face cam, the tie point of clutch shaft bearing and first end face cam is positioned at end face of first end face cam etc. and rises on the curve, one end of driving lever and the first fulcrum A are hinged, the other end and variable density triangle joint, the second edge cam are arranged on the output shaft of the second motor, and the second bearing rolls with the second edge cam and is connected, the tie point of the second bearing and the second edge cam is positioned on the cylinderic earn curve of the second edge cam, pole is hinged on the 3rd fulcrum C, and an end of pole is connected with the second bearing, and the other end is connected with eccentric ratio, the other end of eccentric ratio is connected with T shape slide block, V-arrangement pole is hinged on the second fulcrum B, and an end of V-arrangement pole is connected with slide block on the T shape slide block, and the other end is connected with main density triangular on the variable density triangle, described variable density triangle is by the assist population triangle, main density triangular and microscler slide block form, and are provided with protruding feather key on the assist population triangle, and the middle part of main density triangular is provided with chute, main density triangular is arranged between assist population triangle and the microscler slide block, and the chute that the assist population triangle passes on the main density triangular is connected with microscler slide block.
The present invention compared with prior art has following beneficial effect: the present invention is with the more double-deck density triangular of head density of single layer triangle, the pressing degree of depth by the regulating density triangle, by stepper motor according to the signal controlling instruction, rotate certain step angle, rise curve cam by the grade that is fixedly mounted with on it, drive the swing of driving lever, order about density triangular and slide along head base plate chute, press the difference of the yarn degree of depth to finish the adjusting of density thereby promote the knitting needle realization.Machinery is combined with electrical equipment realized control to height pin bell fabric, realized the adjustment to accurate coil, reduced the defective such as broken hole, broken end of the fracture that causes wool yarn and fabric, adjustable range is wide, knitting precision is high, the Density of braiding is relatively even, stable, reliable, and the sweater fabric that knits out has recessive stereoeffect.
