Description
Technical Field
The invention belongs to the technical field of knitting machinery, and particularly relates to a steel wire conveying device of a flat knitting machine.
Background
Because a certain distance exists between the needle bed opening and the traction device in the flat knitting machine, namely, a piece of fabric cannot be clamped by the traction device immediately when being knitted, if the piece of fabric is directly and normally knitted, the piece of fabric which is just knitted (namely, the piece of fabric which is not clamped by the high-position roller) is not flat due to lack of uniform traction force, so that the whole piece knitting effect of the piece of fabric is influenced, namely, the piece of fabric can be smoothly knitted only in a traction state. Therefore, before entering the formal weaving piece, the weaving piece needs to be woven with the starting fabric with the length of about 25-35mm, after the starting fabric is clamped by a high-position roller below the needle bed opening, the weaving piece can obtain certain traction force to enter the formal weaving, then the 25-35mm starting fabric needs to be woven for transition when each weaving piece is woven, and after the weaving piece is finished, a worker needs to detach the starting fabric (waste yarn) on the weaving piece.
Because some flat knitting machines can be equipped with automatic starting devices, starting rubber-band yarns are needed to be used as starting fabrics, waste yarns are generated, and the starting devices are complex in structure, high in failure rate and relatively high in use cost. 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.
Patent 201820229165. X discloses a play end device, including play end comb, blockade silk, elevating system and thread feeding mechanism, play end comb is provided with many and follows the play end needles of same straight line interval arrangement, the blockade silk cooperates with the cross-under of play end needle, elevating system and play end comb hookup, are used for the drive play end comb makes elevating movement, thread feeding mechanism and blockade silk hookup are used for the drive blockade silk penetrates and takes out the play end needle. This patent is blocked through the mode of the lock silk of piecing together of the back stitch that seals with the loop that the flat knitting machine of computer weaves, blocks the silk and passes the back stitch easily and take out the back stitch, and then makes first line coil can be blocked by the lock silk betterly, makes the tractive force that the piece received more balanced, can reduce to weave the fabric of starting a mouthful, can accomplish the work of tractive fabric again. However, in the above-mentioned device, the conveying length of the seal wire cannot be calculated, and it cannot be accurately determined whether the seal wire has passed through all the lift pins, so that it is easy to cause the seal wire not to completely pass through all the lift pins, which results in the coil on the lift pin falling off, or the seal wire is conveyed too long to be separated from the wire feeding mechanism, which causes a failure.
