Abstract
The invention relates to a roller device of a computerized flat knitting machine and aims to tract fabric by two rollers of the device after the two rollers are open and can still rotate. Traction force can be adjusted via adjustments of a gap between the two rollers; and when the rollers open and close, transmission gear engaging precision can be guaranteed, so transmission gear abrasion can be reduced, interference to a base plate can be avoided and service life of the transmission gear can be prolonged. The technical scheme is that the roller device of the computerized flat knitting machine comprises a left carrying rack, a right carrying rack and two rollers. The roller device is characterized in that the left and right ends of each roller are rotationally positioned on the left and right carrying rack individually via two swinging blocks; a driving assembly driving the two rollers to rotate is installed on the left carrying rack; and an opening-closing assembly driving the two swinging blocks to swing to enable the two rollers to close and open is installed on the right carrying rack.
Description
Technical field
The present invention relates to the roller device of flat machine technical field, specifically Computerized flat knitting machine.
Background technology
Draw-off mechanism is the important component part of Computerized flat knitting machine, effect be produce on old coil suitable drop-down
Power, with the resistance overcoming knitting needle to produce when moving back circle with lasso, has assisted braid movement, and becoming
The fabric of circle deflects from needle-bar fell.Draw-off mechanism mainly includes roller and sinker, and during work, sinker will
Press under coil, roller fabric is drawn.Owing to there being a segment distance between roller and needle-bar fell, must
Base plate can be set up when wanting, risen after base plate rises and downward for the fabric just woven tractive can be led to roller
The position drawn, in playing base plate uphill process, roller must fully open, and is the most just avoided that and plays base plate
Collide.
Conventional roller includes driving roller and passive roller (active and passive roller is usually skin roller), actively
Roller is rotated by driven by motor, and the form engaged by travelling gear passes motion to passive roller.This type of
Roller has following defect: 1, driving roller and passive roller run out of steam and can not rotate after opening, it is impossible to knitting
Thing draws, it is also difficult to regulate the size of pull strength by the way of changing active and passive roller spacing；2、
When driving roller and passive roller are opened, two travelling gears carrying out motion transmission are also turned on, and again close
It is difficult to ensure that the accuracy of mesh during conjunction, easily causes the abrasion of gear；3, driving roller and passive roller are using
During the most full opening of situation easily occurs, limited the rising space of base plate, easily with active sieve
Draw and collide, affect the life-span.

Closing motor drive and engage with gear wheel, gear wheel and two grades of little gears are arranged in same rotating shaft, and two grades little
Gear engages with one of them folding gear.
Described each roller includes a bull stick, and the right-hand member of bull stick is arranged in the installing hole of right side swinging block,
The left end of bull stick through left side swinging block installing hole after fixed described driven gear.
Described each roller includes at least two bull sticks, is linked as one by jack with coordinating of inserted link between bull stick
Fixed by holding screw after body.
It is fixed with bull stick bracket on described rigid rod, bull stick bracket offers the through hole coordinated with inserted link, from
And support the bull stick of roller.
Described roller is ferrum roller.
The invention has the beneficial effects as follows:
1) will drive assembly and folding assembly separately, and not interfere with each other, folding assembly can be by whole for two rollers
Open, when base plate has been provided with for draw-off mechanism, can be prevented effectively from and a base plate is caused obstruction,
Improve service life；
2) utilizing swinging block to drive roller to swing, in swing process, each gear of folding assembly is not mutually disengaged,
The degree that two rollers open can be regulated exactly, control the pulling force to fabric；
3) drive the oscillation center coaxial line installation of the carrier gear in assembly and roller, utilize contiguous block to make
Roller swing time, driven gear can engage with carrier gear all the time without deviating from, it is ensured that gear is nibbled
The precision closed, alleviates the abrasion condition of travelling gear, and can ensure that fabric can be led all the time
Draw, uniform force application；
4) left end of roller is synchronized with the movement in right-hand member moving process to utilize rigid rod can ensure that, and works as sieve
When elongation degree is longer, it is possible to use roller is supported by bull stick bracket, it is to avoid roller flexural deformation；
5) in the present invention, each gear is easy for installation, and dismounting is simple, and service life is long, and precision height (will not be beaten
Sliding), compact conformation, easy to maintenance.
