An anti-wrong weft control device for air-jet loom

Abstract

The invention discloses an anti-wrong weft control device for an air-jet loom, in particular to the field of air-jet looms, comprising an equipment installation side cover, a weft insertion box and an auxiliary weft insertion main nozzle. Ultrasonic nebulizer and humidity sensor are fixedly installed inside the weft insertion box, supporting splints are fixedly installed on the upper and lower ends of the inner side cover of the equipment installation, and electromagnetic coils, vertical guide rods and floating guide wheels are installed on the inner side of the supporting splints , There are permanent magnetic rings on both sides of the floating guide wheel. In the present invention, a magnetic floating guide wheel structure is set, and the same-sex repulsion of magnetism is used to realize the floating installation of the guide wheel. The rotation of the wheel reduces the guiding resistance to the weft, which can adapt to the rapid transmission of the weft insertion of the nozzle, prevents the wrong weft caused by the breakage of the weft, and improves the stability of the air-jet weaving.

Description

technical field [0001] The invention relates to the technical field of air-jet looms, and more specifically, the invention is an anti-wrong weft control device for air-jet looms. Background technique [0002] With the continuous improvement of market demand, the emergence of multi-colored weaving technology puts forward higher requirements for air-jet looms. Air-jet looms are mainly composed of shedding mechanism, air weft insertion mechanism, weft beating mechanism, The weft yarn is drawn into the shed by using the flow of air and the characteristics of jet bunching. The weft insertion mechanism is the core mechanism of the air-jet loom. When the weft yarn is unwound from the weft feeder, the auxiliary main machine The main spray channel composed of the nozzle and the main nozzle is accelerated by the low pressure and put into the shed, and then flies over the shed under the traction of the relay nozzle to complete the weft insertion process. [0003] However, the existing...

Problems solved by technology

[0003] However, the existing weft insertion mechanism still adopts the traditional pulley structure as its thread feeding structure in the lead wire. Because the acceleration air pressure of the nozzle pulls the weft thread too fast, and the friction resistance of the traditional pulley structure is relatively large, it is often used in the thread lead process. The pulling of the weft thread causes the weft thread to break, causing the sequence of the weft thread to be disturbed in the air-jet weaving program, causing a series of wrong wefts in the air-jet weaving. In addition, the weft thread is prone to static electricity when the weft thread is fed when the weft is inserted and fed. When a large amount of static electricity accumulates in the weft insertion mechanism, it is easy to interfere with the weft insertion mechanism, causing the weft insertion to deviate, resulting in interference-type weft error
