Non-contact type power supply device for supplying power to automatic doffer

Abstract

The invention relates to a non-contact type power supply device for supplying power to an automatic doffer, belonging to the technical field of power supply. The power supply device comprises a power supply line, a power frequency power supply and a power receiving unit, wherein the power receiving unit comprises an iron core, a coil and a magnetic body; the power supply line comprises two parallel cables of which the two ends are connected, the power supply line is erected on the path parallel with the track of the automatic doffer through a bracket, and the length of the power supply line is equal to the length of the track; the power frequency power supply is connected with the leading-out end of the power supply line; the iron core is installed at the lower part of a trolley of the automatic doffer; the coil is wound on an intermediate post of the iron core; the power supply line is arranged in two spaces among three posts of the iron core; a magnetic body is arranged under the iron core; and the magnetic body and the iron core together form a magnetic loop. The device can supply power required by the trolley of the automatic doffer in a non-contact power supply mode during operation, and the device has simple structure and low manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of power supply, in particular to a non-contact power supply device for supplying power to an automatic doffing machine. Background technique [0002] The automatic doffing machine includes a mechanical arm for yarn taking and doffing and a trolley moving on the track, and the mechanical arm is installed on the trolley. The mechanical arm and the trolley are powered by the tail wire connected to the trolley, which drives the trolley to move on the track next to the spinning machine. [0003] For the automatic doffing machine, usually its power supply is powered by the power frequency power supply placed on the ground on one side of the spinning machine through the tail wire. The tail wire is connected with the control switch arranged on the dolly. The tail is of sufficient length so that the doffer can run flexibly over the entire track. [0004] However, since the doffing machine needs to drag the power ...

AI Technical Summary

Problems solved by technology

[0004] However, since the doffing machine needs to drag the power supply tail thread to run on the spinning production line of the spinning machine, it will cause inconvenience to the operation of the doffer trolley. May cause the tail to come into contact with or become entangled with equipment in the spinning machine on the production line
