[0002] In the prior art, a knitting needle cylinder for sock machine production generally includes a needle cylinder main body and steel sheets arrayed on the outer periphery of the needle cylinder main body. The steel sheets are welded to the needle cylinder main body by soldering. This type of needle cylinder has the following disadvantages: the knitting needles embedded between the two steel sheets will not move smoothly up and down due to excessive friction in the early stage, and the steel sheets will not be able to clamp the knitting needles better due to wear in the later stage; once the steel sheets are severely worn, the entire knitting needle cylinder needs to be discarded, resulting in a short service life. Utility Model Content

[0005] The outer circumference of the main body is densely covered with syringe grooves arranged along the axial direction of the main body, the shape of the syringe groove corresponds to the plug-in end, the bottom of the syringe groove is spaced from the bottom of the main body, the top of the syringe groove extends to the top of the main body, each of the steel sheets is inserted into the syringe groove from the top of the main body, the top of each of the steel sheets is flush with the top of the main body, the limiting part abuts against the rear end of the syringe groove, and the front end of the support part is flush with the outer surface of the main body;

[0006] It also includes a limiting cover, which is fixed on the top of the main body and closes the top of the syringe groove. The limiting cover limits the top of each steel sheet.

[0007] Specifically, the end angle of the first slope is in an arc shape.

[0008] Specifically, the second slope is trapezoidal.

[0009] Specifically, the cross section of the convex strip is semicircular.

[0010] Preferably, six convex strips are evenly distributed on the front and back sides of the steel sheet.

[0012] Furthermore, the limiting cover is an annular cover body to reduce the deadweight of the limiting cover.

[0013] Furthermore, the limiting cover is provided with a circle of concave ring.

[0014] The beneficial effects of the utility model are as follows: the structural design of the utility model can make the knitting needle embedded between the two steel sheets move up and down more smoothly, which can effectively improve the weaving accuracy of the sock machine and delay the wear of the steel sheet and the knitting needle; the first slope and the second slope are respectively arranged at the front and back ends of the plug-in part, which can prevent the steel sheet from bending to a certain extent, and further ensure the smooth displacement of the knitting needle; at the same time, the steel sheet of the needle cylinder of this structure is a detachable structure. When part of the steel sheet is severely worn, the steel sheet can be replaced by removing the limit cover, which can effectively improve the service life of the needle cylinder.

[0020] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0021] Combination Figure 1-4 As shown, the high-precision knitting needle cylinder for socks machine production includes a main body 1 and a steel sheet 2;

[0022] The rear end of the steel sheet 2 has a plug-in end 3, and the rear end of the back of the plug-in end 3 has a first slope 4, the first slope 4 forms a limit portion, the front end of the plug-in end 3 has a second slope 5, and the second slope 5 forms a support portion. The front and back sides of the steel sheet 2 in front of the plug-in end 3 are evenly distributed with convex strips 6; the purpose of setting the convex strips 6 is to reduce friction with both sides of the knitting needles, so that the knitting needles move up and down more smoothly, and can delay the wear of the steel sheet 2 and the knitting needles;

[0023] The outer circumference of the main body 1 is densely covered with syringe grooves 7 arranged along the axial direction of the main body 1.
