Flat knitting machine automatic stop system and control method thereof

Abstract

The invention relates to the field of textile machinery, and discloses a flat knitting machine automatic stop system which comprises a side thread frame. The side thread frame comprises a frame body,a monitoring assembly, a plurality of jumping rods and a rotating shaft, wherein one end of each jumping rod is connected to the outer side of the rotating shaft in a sleeving mode and is rotationallyconnected to the outer side of the rotating shaft, and a wire ring is fixed to the other end of each jumping rod. A magnetic piece is further fixed to the side face of each jumping rod, and the gravity center of each jumping rod deflects to the side, away from the frame body, of the rotating shaft. The monitoring assembly comprises a monitoring rod located on the side, away from the frame body, of the rotating shaft. The monitoring rod is provided with magnetic sensors equal to the jumping rods in number. When the jumping rods rotate away from the frame body with the rotating shaft as the axial direction, the magnetic pieces correspond to the magnetic sensors one to one and rotate to get close to the magnetic sensors. The magnetic sensors are directly or indirectly electrically connectedwith a working system of a flat knitting machine, electric connection is formed without contact, meanwhile, the requirement for limiting the impact force of the jump rods on the monitoring rod is alsomet, monitoring is sensitive, and shutdown alarm response is rapid and accurate. The invention discloses a control method of the flat knitting machine automatic stop system. The further improvement of the automatic stop system of the flat knitting machine is facilitated.

Description

technical field [0001] The present application relates to the field of textile machinery, in particular to a flat knitting machine self-stop system and a control method thereof. Background technique [0002] The computerized flat knitting machine is a double-needle plate latch weft knitting machine. Its cam device is like a set of plane cams. The stitches of the knitting needles can enter the grooves of the cams, move the cams, and force the knitting needles to move up and down regularly in the needle slots of the needle plate, and through the action of the needle hook and the needle latch. , the yarn can be woven into a knitted fabric. [0003] Existing flat knitting machines are equipped with a side frame for auxiliary yarn supply. The side frame is installed on the side of the flat knitting machine, and the yarn is folded at the side frame to enter the flat function. For example, the notification number is CN202705664U, a kind of side frame for flat knitting machines, w...

AI Technical Summary

Problems solved by technology

However, in order to avoid needle wear and yarn guide wear on the yarn during the weaving process of the flat knitting machine, the yarn will be oiled (coated with grease). When the yarn misses the loop, part of the grease on the yarn and The broken filaments will be scraped off and fly away, while the existing short-circuited bar is located under the yarn, and the flying grease and broken threads are attached to the bar, making the surface of the bar insulated or difficult to contact with the jumper, making it impossible to form Electrical connection, shutdown alarm failure

And it will also be subject to the problem of false positives caused by foreign conductive objects

[0007] Therefore, the alarm sensitivity and accuracy of the existing flat knitting machine self-stop system are insufficient. For the current flat knitting machine, it is necessary to develop a more sensitive and accurate flat knitting machine self-stop system.
