Abstract

The present invention provides a needle selector of flat knitting machine, wherein the needle selector is provided with an oscillating actuator which hardly has adverse action caused by the metal powder generated in the knitting action. The needle selector comprises the following components: a tubular bobbin (10); magnet exciting coils (11) configured on the tubular bobbin (10); a lever component (30) which has one end projected from the bobbin (10) and the other end that is axially supported in the bobbin (10); and magnetic components (a side magnetic yoke (22) and a side magnetic yoke (29)). The lever component is relatively configured with a clamping mode at one end of lever component (30). The lever component (30) uses the electromagnetic force along with the field excitation of magnetic exciting coil (11) for swinging between two side magnetic yokes (22, 29), and the needle selection of knitting needle is executed through the swinging of the lever component (30). Furthermore, the lever component (30) is provided with a covering part (41) which covers a clearance formed between the lever component (30) and two side magnetic yokes (22, 29) from the outside of clearance.

Description

technical field [0001] The invention relates to a needle selection device for a flat knitting machine. In particular, the present invention relates to a needle selection device for a flat knitting machine capable of reducing the possibility of malfunction caused by intrusion of metal powder or the like generated during the knitting operation of the flat knitting machine into an oscillating actuator included in the knitting machine. Background technique [0002] The flat knitting machine includes a needle bed and a cam carriage that reciprocates in the length direction of the needle bed. The length direction advances and retreats and knits the knitted fabric. A knitting needle generally includes a needle body having a hook, a jack for advancing and retreating the needle body as needed, a selector jack, and a selector jack. There are three basic knitting actions performed by this knitting needle: knitting, tucking, and floating. By using the needle selection device mounted o...
