Description

Technical Field

[0001] The utility model belongs to the technical field of signal output of a threading plate of a computerized flat knitting machine, and in particular relates to a zero position signal and orthogonal coding signal output circuit of a threading plate of a computerized flat knitting machine. Background Art

[0002] The computerized flat knitting machine is a double-needle-bed weft knitting machine. It is the main knitting machine for knitting wool and cashmere sweater products. The threading plate of the starting device is one of the important parts of the computerized flat knitting machine. Its main function is to weave the starting fabric with a transition effect to ensure that the traction force on the subsequent fabric is uniform and stable, that is, to ensure the weaving quality of the knitted fabric.

[0003] The bottoming device usually includes a steel wire and a receiving and sending mechanism. When the bottoming needs to be started, the receiving and sending mechanism will send out the steel wire, so that the steel wire passes through each bottoming coil, thereby pulling the bottoming coil to achieve bottoming weaving. After the bottoming is completed, the receiving and sending mechanism will retract the steel wire and withdraw the steel wire from each bottoming coil. This mechanism makes the bottoming process more automated and efficient.

[0004] The travel of the existing steel wire is measured by a mechanical structure. Since the mechanical structure (such as between gear transmissions) has inherent gaps, there will be certain errors in the measurement, which will affect the final braiding quality.

[0005] Therefore, further improvements are made to the above problems. Utility Model Content
