Weft accumulator sensing component and weft accumulator

Abstract

The invention discloses a weft accumulator sensing component and a weft accumulator. The weft accumulator sensing component comprises a sensor seat, a short probe, a medium probe, a long probe, detection contact plates and a motor control panel. The motor control panel is provided with three groups of photoelectric sensors, and the upper side of the sensor seat is provided with a mounting channel.The short probe, the medium probe and the long probe are arranged in parallel in the mounting channel; the middles of the short probe, the medium probe and the long probe are hinged to the left sideof the mounting channel through rotating pins; the left side, the middle and the right side of the bottom of the mounting channel are respectively provided with a left probe hole, a middle probe holeand a right probe hole; one ends of the right ends of the short probe, the medium probe and the long probe, which are located in the mounting channel, are respectively connected with the detection contact plates; the detection contact plates downwards correspondingly penetrates the left probe hole, the middle probe hole and the right probe hole respectively; the left ends of the probes are respectively provided with blocking plates, and the blocking plates are respectively correspondingly arranged above transmitters and receivers of the three groups of photoelectric sensors. The state is sensed by the detection contact plates at the right ends of the short probe, the medium probe and the long probe so as to control the opening, closing and rotating speed of a motor.

Description

technical field [0001] The invention belongs to the technical field of bags, and in particular relates to a sensor component of a weft feeder and a weft feeder. Background technique [0002] The fixed drum type weft feeder at home and abroad basically all adopts the technology similar to CN99200896.4 at present, and the number of parts is less, and the structure is also more compact. However, with the development of high-elastic fabrics on new circular knitting machines, the drum-type yarn feeder specially used for circular knitting machines can no longer meet the requirements, and a fixed drum-type weft feeder with higher performance must be used to adapt to the manufacture of high-elastic spandex yarns. . In addition, due to the increase in the weft insertion rate of economical rapier looms, it has become increasingly difficult for a large number of supporting drum-type weft feeders to meet the growing requirements. Many new economical rapier looms have to choose expensiv...

Problems solved by technology

Among them, the magnetic steel is not only the triggering magnetic field that triggers the Hall element, but also acts as a part of generating the detection pressure. It is difficult to adjust the detection pressure.

If the detection pressure is changed, the trigger magnetic field for the Hall element will be changed at the same time, which may cause the detection failure of the Hall element.
