Description
Technical field
The utility model relates to a kind of jacquard weaving machine, is that a kind of jacquard weaving machine main frame is to the Numerical Control Cam opening synchronous drive mechanism of jacquard weaving machine specifically.
Background technology
Jacquard weaving machine is to control the parts of warp motion on jacquard weaving machine, and jacquard weaving machine comprises jacquard weave main frame and jacquard weaving machine.
The tradition jacquard weaving machine adopts chain or spindle to drive power shaft transmission swiveling wheel after slowing down of jacquard weaving machine, thereby driving, transmission jacquard weaving machine link rod griffes to control shedding, swiveling wheel is simple circular motion, griffing when the warp open without the retention time of its control, can not satisfy the time requirement of wefting insertion line when weaving, cause that the limit yarn breaks and weft yarn is broken, thereby affect weave quality and usefulness.
Summary of the invention
In order to overcome deficiency of the prior art, the utility model provides a kind of drive mechanism simple, manufacturing, easy to use, the conserve space use cost is low, can guarantee effectively that shedding retention time and retention time are adjustable, satisfy the jacquard weaving machine Numerical Control Cam synchronous drive mechanism that loom is waited for the Filling Insertion Time requirement.
in order to achieve the above object, the technical solution adopted in the utility model is: a kind of jacquard weaving machine Numerical Control Cam synchronous drive mechanism, it is characterized in that: comprise jacquard weaving machine main shaft signal generating mechanism, control electronic box, the jacquard weaving machine signal bumps, the jacquard weaving machine approach switch, numerical-control motor and reducing gear, described jacquard weaving machine main frame main shaft signal generating mechanism comprises main shaft initial point signal bumps, main shaft approach switch and clock-pulse generator, main shaft initial point signal bumps is arranged on jacquard weaving machine main frame main shaft, the main shaft approach switch with main shaft initial point signal bumps in the corresponding setting of a certain angle, impulse generator connects with spindle synchronous, the main shaft approach switch is connected with impulse generator and is connected the control electronic box, described jacquard weaving machine signal bumps is arranged on the jacquard weaving machine power shaft, jacquard weaving machine approach switch and the corresponding setting on a certain angle of jacquard weaving machine of jacquard weaving machine signal bumps, the jacquard weaving machine approach switch connects controls electronic box, controls electronic box connection numerical-control motor and connects the jacquard weaving machine power shaft through the reducing gear driving.
Described jacquard main shaft is connected by the numerical control servo motor-driven, and the lock-out pulse of jacquard weaving machine main frame main shaft signal generating mechanism also can directly send by controlling electronic box.
Described jacquard weaving machine main frame main shaft and jacquard weaving machine transfer input shaft speed ratio are 1:1, and a jacquard weaving machine signal bumps is set on the jacquard weaving machine power shaft; Or described jacquard weaving machine main frame main shaft and jacquard weaving machine transfer input shaft speed ratio be 2:1, is symmetrical arranged two jacquard weaving machine signal bumps on the jacquard weaving machine power shaft.
when the jacquard weaving machine opening is maximum, the jacquard weaving machine signal bumps begins to light the jacquard weaving machine approach switch, after the umber of pulse that the main shaft approach switch begins to light or time-delay is put again, control electronic box control numerical-control motor drive jacquard weaving machine static when extremely the jacquard weaving machine approach switch begins to light next time with the synchronization running faster than jacquard weaving machine main frame main shaft from the position that the jacquard weaving machine approach switch begins to light, treat that again jacquard weaving machine main frame main shaft approach switch is lighted next time, repeating has relative quiescent time when above-mentioned action realizes the jacquard weaving machine each run to the maximum open position.
Jacquard weaving machine power shaft and jacquard weaving machine main frame main shaft turn round simultaneously, and both rotating ratio coefficients are larger, and jacquard weaving machine main frame main shaft residue angle is larger, and the relatively static opening time of jacquard weaving machine is longer.
The beneficial effects of the utility model are: the swiveling wheel that when jacquard weaving machine is synchronized with the movement with the jacquard weaving machine main frame, jacquard weaving machine control is griffed becomes the motion mode with certain open retention time by simple circular motion, it is static that thereby the control shedding has maintenance, guarantee that jacquard weaving machine has sufficient Filling Insertion Time, guarantee that wefting insertion fully completes, reduce warp end break, especially better to the Looms effect, be conducive to improve weave quality and weave usefulness.
The utility model arranges respectively corresponding signal bumps and approach switch on jacquard weaving machine main frame main shaft and jacquard weaving machine power shaft, by control anglec of rotation official post that electronic box controls diaxon separately signal bumps connect approach switch and exist the regular hour poor, time difference guarantees to griffe the wait Filling Insertion Time of opening thus, be convenient to stablize wefting insertion, avoid disconnected limit yarn and weft yarn that the Filling Insertion Time deficiency causes to hang up phenomenon, be conducive to improve weave quality and efficient, also simplified gearing because having cancelled transmission main shaft simultaneously, saved the space, eliminated potential safety hazard.
