Technical Field

The utility model relates to a knitting machine technical field specifically is an automatic threading board device of flat-bed machine.

Background

The flat knitting machine is a machine for knitting by using a transverse knitting needle bed, and is a machine for finishing loop knitting by matching yarns with knitting needles, wherein yarns are driven by a machine head to move back and forth on the needle bed full of knitting needles, and the knitting machine is a flat knitting machine, which belongs to one kind of knitting machinery and generally adopts the transverse knitting machine.

The flat knitting machine can complete the knitting of a complete piece of knitting, a complete piece of knitting generally mainly comprises parts such as waste yarn, stitches removing, starting, idle running, rib knitting, big body and the like, and because the pulling output process of the knitted fabric after the knitting is finished draws the formed knitted fabric out of a knitting area and sends the knitted fabric out after a certain traction force is given to the knitted fabric, the traction force has great influence on the knitting process and the product quality, and the flat knitting machine has the following basic requirements: because the looping process is continuously carried out and the traction movement is required to be continuously carried out, the traction force acting on each coil needs to be stable, uniform and consistent, and the traction amount in the unit time of the traction force needs to be synchronously carried out in the looping process, a certain distance exists between a needle bed port and a traction device in the flat knitting machine, namely, a fabric piece cannot be clamped by the traction device immediately when being knitted, at the moment, if the normal knitting of the fabric piece is directly carried out, the fabric piece which is just knitted (i.e. the fabric piece which is not clamped by a high-position roller) is uneven due to lack of uniform traction force, so the whole knitting effect of the fabric piece is influenced, namely, the fabric piece can be smoothly knitted only in the traction state, therefore, before entering the formal knitting of the fabric piece, the starting fabric with the length of 25-35mm needs to be knitted firstly, and after the starting fabric is clamped by the high-position roller below the needle bed port, the weaving pieces can obtain certain traction force and enter formal weaving, so that 25-35mm of the starting fabric needs to be woven for transition when one weaving piece is woven, and after weaving of the weaving pieces is finished, workers need to detach the starting fabric (waste yarn) on the weaving pieces. Because some flat knitting machines can be equipped with automatic starting devices, starting rubber band yarns are required to be used as starting fabrics, waste yarns are generated, the starting devices are complex in structure and high in failure rate, and the use cost is relatively increased. Therefore, the conventional flat knitting machine needs to realize the integral knitting of the knitted fabric piece by using the waste yarn before starting the knitting, so that the integral working efficiency is reduced, and the yarn is wasted.
