Description

Technical Field

[0001] The utility model relates to the technical field of flat knitting machines, in particular to a wire inlet buffer rack for a flat knitting machine. Background Art

[0002] With the rapid development of economy and the continuous improvement of people's living standards, people have higher and higher requirements for clothing quality and grade. Therefore, the performance requirements of knitting machines closely related to clothing processing are naturally improved. With the continuous improvement of the mechatronics technology level of knitting machines, more and more knitting machines have added automatic control functions. At present, various automatic control functions have been applied to knitting machines to varying degrees.

[0003] Every time the head of the computer flat knitting machine moves, the pulling force and movement displacement on the spinning yarn are sometimes large and sometimes small, resulting in inconsistent tension on the spinning yarn. The tension is uneven, and due to the limitations of the wiring method, it leads to tight wire breakage or loose knotting in the actual production process, causing equipment shutdown and affecting production efficiency. The existing flat knitting machine itself will have a tension adjustment mechanism at the wire inlet to adjust the tension fluctuation of the spinning line. Although the problem is alleviated to a certain extent, the adjustment space is limited to a certain extent. When the tension fluctuates greatly, there is still a risk of wire breakage. In addition, the existing adjustment arm adopts a straight arm design, which will cause the adjustment arm to hit the wire roller when the spinning line is taut. The general solution is to limit the rotation angle of the adjustment arm by adding a limiter. Although this solves the problem, it will also cause the adjustment space to become smaller, and there is further room for improvement. Utility Model Content
