Description

Yarn pressing device for warp knitting machine

technical field

The utility model relates to a yarn pressing device of a warp knitting machine, which belongs to the technical field of textile machinery.

Background technique

One or several groups of yarns arranged in parallel are formed into loops at the same time on all the working needles of the warp feeding machine to form a knitted fabric. This method is called warp knitting, and the fabric is called warp knitted fabric. The knitted machine is called a warp knitting machine. The warp knitting machine is mainly composed of a knitting mechanism, a bar traverse mechanism, a warp let-off mechanism, a pulling take-up mechanism and a transmission mechanism. There are many yarn pressing devices on the market at present, and some yarn pressing devices The structure is mostly one-piece structure, which is inconvenient to use. Some yarn pressing devices lack a fault reminder system. When a fault occurs, the yarn pressing device is easily damaged, and even causes the entire warp knitting machine to fail, reducing the service life of the warp knitting machine.
