Infrared magnetic field float yarn sensor for computer flat knitting machine

Abstract

The invention relates to an infrared magnetic field float yarn sensor for a computer flat knitting machine. The infrared magnetic field float yarn sensor comprises an infrared probe, an infrared detection circuit board, positioning screws, a probe slice, a base station, a rotating hole, a positioning bolt, an LED lamp, a Hall switch H, a Hall switch J, a Hall switch K, a steel magnet and a rotating shaft, wherein the infrared probe is fixedly arranged by the positioning screws and is connected to the infrared detection circuit board, and the rotating hole penetrates through the base station; the middle end of the probe slice sleeves the front end of the rotating hole and then is fixed through the positioning bolt, and a round hole is also formed in the probe slice; the status of the LED lamp is displayed through the round hole, and the steel magnet is arranged at the front end of the rotating shaft; the rotating shaft is synchronously connected with the probe slice, and the Hall switch H, the Hall switch J and the Hall switch K are arranged in the infrared detection circuit board inside the base station according to preset positions. The float yarn sensor provided by the invention has the advantages of having high detecting precision, effectively avoiding a false alarm caused by slight jitter and mistaken collision of the probe slice, greatly improving production efficiency, and reducing production cost.

Description

technical field [0001] The invention relates to the technical field of knitting machinery circuits, in particular to an infrared magnetic field floating yarn sensor for a computerized flat knitting machine. Background technique [0002] my country is a major producer and exporter of textile products. More than 70% of the world's textiles are produced in China, which has made a great contribution to my country's foreign exchange reserves. As an important knitting machine, the computerized flat knitting machine plays a pivotal role in the textile industry. During the knitting process of the computerized flat knitting machine, in order to make the knitting continue, the knitting is mainly completed by the mountain plate, the needle plate and the knitting needles of the computerized flat knitting machine. During normal operation, the knitting needles weave and process the yarn continuously on the front and rear needle plates to obtain knitted fabrics. During the weaving proces...
