The specific embodiment

The utility model is the improvement of carrying out on Chinese utility model patent ZL200910135618.8 basis, main improvement is that top griffes drive unit, cancelled former upper axle and the lower shaft that runs through design, adopt left and right two covers to griffe drive unit and drive respectively the upper and lower device of griffing, thereby the middle part of upper rack do not had stopping of upper axle and lower shaft, like this, when the upper and lower device of griffing while breaking down, need not dismantle axle and lower shaft, facilitate maintenance.Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1 and Figure 2, the computer jacquard that the utility model provides, comprise frame 10 and be arranged on the upper and

lower device

20,30 of griffing in frame 10, the bottom of frame 10 is provided with main shaft 40, the two ends of main shaft 40 are respectively equipped with upper and lower

axis cam linkage

50,60, main shaft 40 drives left and right two covers to griffe drive unit 70 by upper and lower

axis cam linkage

50,60, thereby drives upper and lower device 20, the 30 upper and lower reciprocating motions of griffing.

Refer to Fig. 3, Fig. 4 and Fig. 5, frame 10 comprises two outer panels 11 and two interior plates 12 that are separately positioned on outer panel 11 inboards again, and the end face of outer panel 11 and interior plate 12 is separately fixed on top board 13, forms left and right two accommodation spaces.

Griffing drive unit 70 comprises axle 71 and lower shaft 75, sheathed the first fork 72, upper fixed seat 73 and the second fork 74 of being fixed with successively on upper axle 71, the first fork 72 and the second fork 74 are arranged between inside and

outside side plate

12,11, and be separately fixed on the two sides of upper fixed seat 73 free end of the first fork 72 and the second fork 74 forward and backward symmetry in vertical plane; Sheathed the 3rd fork 76, lower fixed seat 77 and the 4th fork 78 of being fixed with successively on lower shaft 75, the 3rd fork 76 and the 4th fork 78 are arranged between inside and
