Description

Technical Field

[0001] The utility model relates to the technical field of circular knitting needles, in particular to a circular knitting needle. Background Art

[0002] Circular knitting machine, scientifically known as circular weft knitting machine (or circular weft knitting machine), has developed rapidly due to its multiple loop forming systems (called yarn feeding paths or loop forming paths in enterprises, referred to as paths), high speed, high output, fast pattern change, good fabric quality, few processes and strong product adaptability. In the knitting process of circular knitting machine, knitting needles are generally used. The knitting needles are mainly composed of a needle bar, a knitting hook and a needle butt. The knitting hook is located at the top of the needle bar and is mainly used for knitting the thread. The knitting needle circular machine is generally equipped with a base, a displacement sensor and a triangle. The needle bar on the knitting needle is connected to the base. The slide groove on the base is slidably connected, and the needle butt in the knitting needle is connected to the triangle. Through the movement of the triangle, the needle bar rises and falls, thereby realizing the weaving of the thread. When the knitting needle rises and falls, the bottom surface of the knitting needle is generally connected to the displacement sensor fixedly connected to the base. The displacement sensor is a pull rope linear displacement sensor. By tying a knot at one end of the stretching and connecting it to the bottom of the needle bar, the pull rope is driven to move by the rise and fall of the knitting needle, thereby detecting the rise and fall of the knitting needle. However, since the slide groove on the base for the knitting needle to slide is used to limit the knitting needle, the slot is opened just to the size of the knitting needle sliding to prevent the knitting needle from shifting back and forth;

[0003] Although the ups and downs of the knitting needle can be monitored by connecting the weaving rod and the displacement sensor through a knotted rope, the slot on the base for the knitting needle to slide is adapted to the knitting needle. If the pull rope of the displacement sensor is knotted and connected to the bottom of the needle rod, the knitting needle will rise and fall with the pull rope, and when the bottom of the knitting needle moves into the slide groove, the knitting needle will drive the pull rope to move. Once the knitting needle moves into the slide groove, the knot at the bottom of the needle rod will be stretched and will inevitably hit the slide groove. When entering the slide groove, the knotted part will hit the slide groove for a long time, which will affect the smoothness of the sliding of the knitting needle and the fixity of the knot between the needle rod and the pull rope. Summary of the invention

[0004] The utility model aims to solve the problems in the prior art and provides a knitting needle for a circular knitting machine, which can prevent a knotted part from hitting a slide groove.
