Utility model content

The purpose of this utility model is to provide a kind of in needle selecting knife reaction speed one timing, can improve needle selecting knife and stir the reaction compartment of pattern bit, improve and choose the knitting slide cam selector of the modified of accuracy rate.

For achieving the above object, the technical solution of the utility model is: the knitting slide cam selector of modified, comprise slide cam selector housing and can a plurality of needle selecting knifes be arranged at intervals at below housing of left and right swing, described each needle selecting knife free end is respectively to the oblique extension in side, form a pressing surface tilted, form one between the pressing surface that it tilts and bottom water plane and be pressed into chamfering a, the angle of described this press-in chamfering a is between 34 ~ 36 degree, and the height on its pressing surface tilted is between 3.71 ~ 4mm.

Further improvement: the angle of described this press-in chamfering a is 35 degree, the height H on the pressing surface of described inclination is 3.85mm

By adopting technique scheme, the beneficial effects of the utility model are: compared with prior art, improvement of the present utility model is the press-in angle of original needle selecting knife to be increased between 34-36 degree by 29 degree, thus indirectly extend the time that pattern bit jacquard weave tooth enters needle selecting knife, namely the reaction compartment of needle selecting knife is relatively added, it is not when changing profound long L distance between adjacent pattern bit group, when not changing the reaction speed of dials linear velocity and needle selecting knife yet, just the press-in angle of needle selecting knife is changed slightly, just can when benefit, improve the reaction compartment of each needle selecting knife of slide cam selector, owing to adding the reaction compartment of needle selecting knife, make slide cam selector needle selection more accurate, decrease and falsely drop or the wrong phenomenon selected, avoiding jacquard weave tooth, to enter time of needle selecting knife too early, the reaction compartment of needle selecting knife is little and cause can not accurate needle selection, the phenomenon of wrong flower is there is when then causing loom to be produced.Need saying of explanation: because the press-in chamfering a of needle selecting knife cutter head is larger, the pressure angle that the jacquard weave tooth of pattern bit contacts with it is larger, pressure angle increases, interaction force between parts increases naturally, wearing and tearing are also just along with just increasing, if thus pressure angle is unconditionally increased, the service life of pattern bit will be reduced, for this reason, it is the most suitable that applicant is just found the press-in angle of needle selecting knife to change between 34-36 ° through repetition test, it can slightly elect additional member the reaction compartment of pin jet blade can avoid again the jacquard weave tooth heavy wear of pattern bit, thus avoid needle selecting knife cutter head because of increase press-in chamfering a, and cause the wearing and tearing of the jacquard weave tooth accelerating pattern bit, reduce the defect in pattern bit service life.
