A circular knitting machine

Abstract

The invention discloses a circular knitting machine, comprising a split-type upper plate needle cylinder and an upper jacquard plate arranged on the outer ring of the middle kernel. The upper jacquard plate is located above the split-type upper plate needle cylinder; There are multiple needle selector installation grooves, needle selectors are arranged in the needle selector installation grooves, the upper disc saddle is connected to the relative upper part of the outer ring of the upper jacquard disc, and the reset triangle is connected to the opposite lower part; Jacquard inserts are provided, and jacquard inserts are inserted into the jacquard inserts. One end of the jacquard inserts is a fulcrum end, and the bottom of the fulcrum end is provided with a positioning fulcrum. The split-type upper disc needle cylinder is provided with a positioning fulcrum slot that matches the positioning fulcrum; jacquard The top of the piece is provided with needle selection teeth, and the top of one end of the jacquard piece away from the fulcrum end is provided with a reset foot. The needle cylinder of the invention is simple to process, the upper plate saddle is convenient to disassemble and assemble, and the setting of the reset triangle is more reasonable and the function is stronger.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a circular knitting machine. Background technique [0002] The traditional circular knitting machine has exposed some insurmountable problems in the use process. In order to install the jacquard inserts and knitting needle inserts on the needle cylinder, a number of equally divided insert grooves are milled on the surface of the needle cylinder, and the jacquard inserts are milled. The knitting needle inserts and the knitting needle inserts are respectively inserted into the insert grooves. The existing needle cylinder is an integral structure. The milling cutter feeds from the left side, first mills the jacquard insert groove, and then retracts the knife to mill the knitting needle insert groove. , the slot is deeper, but the deeper the slot is, the more difficult it is to process, which increases the processing cost.

Problems solved by technology

[0002] The traditional circular knitting machine has exposed some insurmountable problems during use. In order to install the jacquard inserts and knitting needle inserts on the needle cylinder, there are several equally divided insert slots milled on the surface of the needle cylinder. The jacquard inserts and knitting needle inserts are respectively inserted into the insert slots. The existing needle cylinder is an integral structure. The milling cutter enters from the left side, mills out the jacquard insert slots first, and then retracts to mill out the knitting needle insert slots. , the groove is deeper, but the deeper the groove is, the more difficult it is to process, which increases the processing cost

In order to cooperate with the positioning fulcrum of the jacquard piece, a matching positioning fulcrum groove needs to be provided on the needle cylinder. During the processing of the existing needle cylinder, in order to ensure the depth of the jacquard insert groove, the positioning fulcrum groove is also milled into several thin slices. affect the overall structure

[0003] When the existing circular knitting machine removes the upper saddle, due to the blocking of the upper needle selector, it is necessary to remove the upper needle selector one by one, and then the upper saddle and the needle selector can be disassembled one by one, resulting in It is extremely cumbersome to replace the upper cam or the saddle, and the workload is huge. When the circular knitting machine is knitting patterns of different specifications, it is often necessary to disassemble or replace the cam or the saddle, resulting in work Inefficiency affects production progress

[0004] In addition, the reset foot of the traditional jacquard sheet is set on the top of the fulcrum end of the jacquard sheet, and the reset triangle is located inside the needle selector. The reset of the jacquard sheet is realized by matching the reset triangle and the reset foot. However, the distance between the reset foot and the positioning fulcrum is relatively short. , so that the lever force required for the reset of the jacquard piece is relatively large, and the wear and tear on the reset triangle and the reset pin is also large; in addition, because the reset pin is on the inner side of the needle selection tooth, when replacing the jacquard piece, it is necessary to remove the needle selector first, and then It is cumbersome to remove the reset triangle and then remove the jacquard piece
