Woof doubling detecting device and using method

Abstract

The invention discloses a woof doubling detecting device which comprises a base, wherein a pay-off wheel is rotatably connected with one end of the top of the base; a doubling machine is fixedly connected with the other end of the top of the base; an air cylinder is fixedly connected with one side of the pay-off wheel; a woof bunching sleeve is arranged at the top of the air cylinder; a bracket isfixedly connected with one side of the doubling machine; a driving roller is arranged at the top of the bracket; a motor is arranged at one end of the driving roller; and a detecting rack is arrangedbetween the air cylinder and the bracket. According to the woof doubling detecting device, a woof is tensioned to stress an eye shaped shuttle, a movable rod compresses a first spring to limit a metal ball at the top end of a sliding rail, a tension sensor is cooperated with a single-chip microcomputer to intelligently control the air cylinder to stretch and draw back, the stress size to the woofis adjusted, and the woof fracture risk is reduced; when the woof breaks, the first spring resets, a blocking piece moves away, the metal ball accelerates to move to burst open a swing link and reachthe top end of an infrared sensor, and the infrared sensor is cooperated with the single-chip microcomputer to intelligently control a motor and a buzzer to work so as to improve the woof doubling effect.

Description

technical field [0001] The invention relates to the technical field of textile thread detection, in particular to a weft thread doubling detection device and a use method. Background technique [0002] The existing doubling machine is to form a multi-ply yarn by doubling multiple single-ply yarns. During the doubling process, when the tension is high, the wefts are easy to break, and when the tension is small, the wefts are loose. flaw. When one of the weft yarns breaks, but the operator does not find out in time, the yarns produced during the thread breakage process and the normal yarns will have fewer strands and smaller diameters, which will affect the normal use and quality of the yarns. Therefore, it is necessary to install a detection device on one side of the doubling machine.

Problems solved by technology

[0002] The existing doubling machine is to form a multi-ply yarn by doubling multiple single-ply yarns. During the doubling process, when the tension is high, the wefts are easy to break, and when the tension is small, the wefts are loose. flaw

When one of the weft yarns breaks, but the operator does not find out in time, the yarns produced during the thread breakage process and the normal yarns will have fewer strands and smaller diameters, which will affect the normal use and quality of the yarns. Therefore, it is necessary to install a detection device on the side of the doubling machine

[0003] At present, the weft weft deficiency detectors used by shuttleless looms at home and abroad mainly include mechanical arm detection type and piezoelectric ceramic type. Among them, the mechanical arm detection type is easy to accumulate flowers inside the probe after a long-term use in the workshop for a certain period of time, and is prone to leakage. The phenomenon of balancing the tension of the yarn is to adjust the pressure of a compression spring by feeling, so that the tension between the yarns is as consistent as possible, and it is easy to cause artificial tension inconsistency.

However, the cost of the piezoelectric ceramic micro-displacement detection device is too high, and when the device is matched with the shuttleless loom, there are requirements for the connected model, so it cannot be applied to other types of looms, and the detection device does not have a balanced yarn Tension devices, such devices are difficult to be widely used
