Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of knitting machine equipment, more specifically to a textile needle cylinder with tension balancing device. BACKGROUND

[0002] The circular knitting machine is also called circular weft knitting machine. The circular weft knitting machine can be classified according to the type of knitting needle, the number of needle cylinder, the configuration form of needle cylinder, and the movement of knitting needle. The circular weft knitting machine mainly consists of a yarn feeding mechanism, a knitting mechanism, a pulling and winding mechanism, and a transmission mechanism. The needle cylinder is an essential part of the knitting machine, which can drive the knitting needle to move up and down to perform knitting operation. The outer wall of the needle cylinder is usually provided with a plurality of groups of needle grooves, and the yarn is spun in the needle grooves. The existing circular knitting machine has some use drawbacks in the use process: first, the rear side wall of the needle groove is fixed, and the fabric fed into the needle groove by the yarn feeding mechanism is prone to have too large or too small supporting force, which can cause the fabric to be loose or too tight during spinning, affecting the quality of spinning. In addition, the continuous friction between the fabric and the side wall of the needle groove during spinning can cause the needle groove to wear, affecting the service life of the needle cylinder, and the needle cylinder needs to be replaced frequently, reducing production efficiency and increasing production cost of enterprises. The above problems need to be solved urgently. In view of this, the present inventor proposes a textile needle cylinder with tension balancing device, which sets a tension balancing device on the rear side wall of the needle groove, so that the tension can be automatically adjusted during yarn spinning, ensuring the quality of spinning and prolonging the service life of the needle cylinder.

[0003] In order to solve the problem of tension balance during yarn spinning, a circular knitting machine double-sided needle cylinder fabric tension balancing structure is disclosed in Chinese patent (grant announcement number: CN217895887U).

The number of connecting frame support arms is five, a wire feeding frame is arranged at the top end of the connecting frame, coils are uniformly arranged on the outer wall of the wire feeding frame, a plurality of support frames are fixedly installed at the top end of the connecting frame, a support ring is fixedly installed at one end of the support frame, a pair of hydraulic rods are fixedly installed on the inner wall of the support ring, and a balance bar is fixedly installed at one end of the pair of hydraulic rods. The utility model can effectively prevent the fabric from winding and not being tight enough when discharging, thereby improving the efficiency and stability of fabric processing.

[0004] The scheme still has some deficiencies in application, the yarn needs to keep tension balance when spinning on the needle groove of the needle cylinder, otherwise, over-looseness can cause winding and over-tightness can cause yarn breakage, affecting spinning quality and production efficiency, meanwhile, continuous friction between the yarn and the rear sidewall of the needle groove can easily cause shortening of the service life of the needle cylinder, in addition, friction between the upper surface of the needle cylinder and the sinker can also cause damage, which is another reason for short service life of the needle cylinder, therefore, the structure of the needle cylinder needs to be improved to have tension balance function, improve spinning quality, and also have wear-resistant function to prolong the service life of the needle cylinder.
