Described crank inserts in sliding sleeve slidably, and the inside of sliding sleeve is provided with rubber inner sleeve, and sliding sleeve is fixed on the end of main shaft by fixed structure, the axis of sliding sleeve and the axes normal of main shaft.
The jointed shaft of described crank and connecting rod stretches out towards cam path and is installed with described conical roller, and one end that jointed shaft stretches out is fixed with a back-up ring, back-up ring and be provided with adjusting washer (disk) between crank and rod hinge connection place.
Described rocking bar offers regulating tank, and the jointed shaft of rocking bar and connecting rod is positioned in regulating tank by adjusting nut.
Described fixed structure comprise two semicircle boss and one hold hoop tightly, described two semicircle boss are separately fixed at the end of main shaft and the outer wall of sliding sleeve, and two semicircle boss are spliced into cylindric and are fixedly connected with by holding hoop tightly.
Operation principle of the present utility model is: main axis, sector gear reciprocally swinging is driven by crank and rocker mechanism, sector gear driving pinion axle does forward and reverse rotation (this process traverse is exaggerated), and the sword belt wheel that pinion shaft is installed drives sword belt to move back and forth and realizes wefting insertion action (this process traverse is exaggerated); In the process of crank and rocker mechanism work, conical roller meeting periodic variation crank position in sliding sleeve in the process of cam path movement of the covert footpath mechanism of cam path, thus changing the amplitude of fluctuation of rocking bar, the final characteristics of motion changing sword belt, realizes wefting insertion action.
The beneficial effect that the utility model has is: the utility model drives sword belt to take turns by crank and rocker mechanism, sector gear and pinion, drive sword belt moves, and the amplitude of fluctuation of sector gear is regularly changed by cam path, only need design different cam paths can change wefting insertion rule, easy to adjust and precision is higher, overall structure is simple, easy to manufacture, cost is lower.
