Wherein, preferably, described cutoff groove is an arc, thereby easier processing is also more attractive in appearance.
Wherein, further preferably, described cutoff groove is of a size of R0.5～5mm, and the degree of depth is 0.1～10mm, under this size, can not only guarantee to quench successfully, and processing easily.
Wherein, preferably, described inserted sheet is the straight line inserted sheet of two ends gage distortion.
Beneficial effect: a kind of improved cylinder of knitting loom provided by the invention with respect to the advantage of prior art is:
1: owing on the inclined-plane of syringe actinal surface, be provided with the cutoff groove, therefore make the actinal surface of syringe thinner, be easy to be heated, temperature raises fast, just can reach hardening heat very soon, thereby has accelerated the quenching process, shortened the cool time, biography speed slows down under the simultaneous temperature, so can not be out of shape, not only guarantees constant product quality, also improved the yield rate of product, in use, improve the service efficiency of equipment, prolonged its service life;
2: change inserted sheet into the straight line inserted sheet by the embossing inserted sheet, change the face contact into by a contact, thus not easy to wear, improve the service life of needle cylinder insertion and knitting needle, need not often change and keep in repair, saved production cost, frictional force is little simultaneously, has improved production efficiency to a certain extent;
3: its gauge of the easier control of straight line inserted sheet of face contact, thus can guarantee that knitting needle and outer needle tray coincide, stable in the knitting needle motion process, can not swing, keep the knitting needle motion smooth and easy, reduce outage rate, improve throughput rate, guarantee the quality of fabric;
4: the straight line inserted sheet can not be stained with materials such as dust, and is easy to use;
