Infrared yarn breakage automatic alarm device

Technical Field

The application relates to the field of yarn detection, in particular to an infrared yarn breakage automatic alarm device.

Background

Curtains, cloths, carpets, etc. used in life are all woven by threads and yarns by various weaving devices. The knitting equipment comprises a frame placed on the ground, wherein the frame is provided with a knitting mechanism, a warp let-off mechanism and a traction and curling mechanism, one or more groups of yarns which are arranged in parallel and are unreeled from a warp beam by the warp let-off mechanism are knitted on knitting needles which are fed into the knitting mechanism in the warp direction to form a fabric with a certain organization structure, and finally the fabric is drawn from the knitting mechanism and coiled into a cloth roll by the traction and curling mechanism.

However, during yarn production, winding and warping, yarn breakage occurs when the yarn tension on the needles is greater than the maximum yarn tension that the yarn can withstand. At present, most textile enterprises still stay in the manual detection stage for detecting yarn breakage, and in the working process of the braiding equipment, workers need to walk in a workshop all the time to observe the state of the yarn so as to stop the equipment in time for wiring under the condition of yarn breakage. However, because the motor of the knitting equipment moves in a fast rotation mode, if the knitting needles on the equipment are in a high-frequency shaking state, if yarn breakage occurs, workers only have difficulty in directly judging the broken yarns on the fast-moving equipment by naked eyes, so that the broken yarns can not be found out in time to stop the operation of the equipment, the broken yarns are directly knitted into fabrics together with other yarns without wiring treatment, the surfaces of the knitted fabrics are caused to have cracks with a certain length, the cracks can lead to disqualification of the whole fabrics, and therefore, raw materials are wasted, and the loss of enterprises is increased.
