Yarn pressing device for plastic cylinder knitter shuttle

Abstract

The invention relates to a yarn pressing device for a plastic cylinder knitter shuttle. The yarn pressing device is installed in the middle in a cylinder knitter shuttle body. The yarn pressing device comprises a yarn pressing plate, a tension spring base and a tension spring. The tension spring base is installed in the shuttle body, one end of the tension spring is hung on the tension spring base, and the other end of the tension spring tensions the yarn pressing plate. The yarn pressing plate is installed in the shuttle body, and wire brushes are installed on the upper surface of the yarn pressing plate and are each of a flat enclosed structure formed by winding steel wires. Compared with an original yarn pressing plate structure, surface contact or line contact between a weft bobbin and a yarn pressing plate is changed into line contact or point contact between a weft bobbin and the steel brushes, abrasion to yarn is weakened, the situation that the yarn is burned and broken due to large-area friction heating is avoided, the resistance applied by the yarn pressing late to the weft bobbin through the steel brushes can be stable, and the tension produced by weft in the process of knitting can be constant.

Description

technical field [0001] The invention relates to the technical field of plastic cylinder knitting machines, in particular to a yarn pressing device for a plastic cylinder knitting machine shuttle. Background technique [0002] The yarn pressing device for the shuttle of the plastic circular loom is specifically a yarn pressing plate structure installed in the shuttle of the circular loom. The tension of the weft yarn can stop the rotation of the weft yarn bobbin quickly after the weft yarn breaks. [0003] The original structure of the yarn pressing board for the shuttle of the circular loom is a structure where a piece of skin is pasted on the place where the yarn pressing board and the weft bobbin are in contact. If the surface is too large, it is easy to heat up and burn the weft yarn, causing the weft yarn to be thrown out and causing the warp yarn to be broken by the weft ribbon. Sometimes the situation is very serious. In order to prevent the weft yarn from being scal...
