Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of textile equipment technical field, specifically to a kind of knitting circular knitting machine tube yarn support frame structure. BACKGROUND

[0002] Due to the loop-forming system of the knitting circular knitting machine, it has high speed, high yield, fast pattern change, good fabric quality, fewer processes and strong product adaptability, so it develops very quickly. Currently, the existing technology of knitting circular knitting machine tube yarn stand generally adopts the structure of multiple tube yarn supports on one support. However, during use, the existing knitting circular knitting machine tube yarn support frame cannot be adjusted in height, and the yarn tension cannot be adjusted according to the parameters of the fabric using the height adjustment of the support frame.

[0003] By adjusting the height of the support frame, the path length and bending degree of the yarn before entering the knitting area can be changed, thereby accurately controlling the yarn tension. Excessive or insufficient tension will affect the fabric quality, such as causing uneven loop length and horizontal stripes on the fabric. The height adjustment function makes tension control more flexible and can adapt to different yarn characteristics and fabric process requirements. Reasonable tension can prevent yarn from being damaged in terms of elasticity, elongation, and physical and mechanical properties. Height adjustment helps to control tension within a reasonable range and protect yarn quality. For the process of unwinding the tube yarn, height adjustment of the support frame helps to maintain the stability of yarn unwinding, prevent breakage or entanglement of yarn due to poor unwinding, and improve production efficiency.

[0004] In the prior art, the patent document with publication number CN213172828U discloses a knitting circular knitting machine tube yarn support frame structure. The knitting circular knitting machine tube yarn support frame structure is provided with a motor box, a rotary motor, a through hole, a movable cavity, a rotary bearing and a rotary lead screw on the support column. The rotary lead screw is connected to the movable shaft through the external threads of the rotary lead screw. The movable shaft is fixedly connected to the tube yarn large circular support through the connecting rod. The movable shaft moves up and down on the outside of the rotary lead screw through the rotation of the rotary lead screw. The connecting rod drives the tube yarn large circular support to move up and down, achieving the effect of lifting and lowering and facilitating height adjustment. During height adjustment of the support frame, the support frame is supported by a single point. The single-point support may be inclined and unbalanced. When the tube yarn large circular support bears a large load, the single-point support may sway, affecting the uniformity of yarn tension control. In addition, the threaded connection between the movable shaft and the rotary lead screw may wear out after long-term use, resulting in gaps during lifting and lowering, and the stability of the support frame is weak.
