Description

TECHNICAL FIELD

[0001] The utility model relates to knitting circular knitting machine technical field, concretely relates to a knitting double -faced large circular knitting machine needle cylinder with cloth supporting function. BACKGROUND

[0002] The needle cylinder is one of the core components of the circular knitting machine, and knitting needles are installed on the needle cylinder. The needle cylinder rotates during the operation of the machine to drive the knitting needles to perform knitting actions. In the prior art, such as patent publication No. CN202644083U, a knitting assembly improvement structure of a large circular knitting machine is disclosed, which comprises a needle disc and a needle cylinder arranged in correspondence with each other. The needle disc and the needle cylinder are provided with needle grooves at equal intervals by inserting sheets. The corresponding ends of the sheets on the needle disc and the needle cylinder are located on the inner sides of the edges of the needle disc and the needle cylinder, respectively, so that the yarn loop is not affected by the sheets at the cylinder port of the needle cylinder. Since there is no loop-forming resistance, the yarn can be prevented from pilling. However, due to the downward tension of the cloth rolling machine, the tension on the lower single edge is greater than that on the upper disc. In addition, after the yarn is looped, the cloth slides along the inner side of the needle cylinder due to the friction between the cloth and the inner wall of the needle cylinder. As a result, the lower disc is more prone to defects than the upper disc, which affects the loop-forming quality of the lower disc and is not conducive to further improving the cloth surface quality.
