Abstract

The invention provides a power-off yarn remaining device for rotor spinning, and belongs to the technical field of power-off devices. The device comprises a first servo motor, a second servo motor, athird servo motor, a fourth servo motor, a first frequency converter, a second frequency converter, a third frequency converter, a fourth frequency converter and a direct bus. The device has the advantages that on the condition of sudden power off, due to the inertia effect, the first servo motor, the second servo motor, the technological fan, the impurity removal fan and other motors can still run for a period of time, and in the period of time, voltage output of the direct bus of the first, second, third and fourth frequency converters is still powered; in the period of time, a PLC sends aninstruction to the third and fourth servo motors to be stopped after detecting that equipment is powered off suddenly, and yarn remains in a yarn guiding pipe. Slow stopping is performed when other motors are powered off, yarn can be completely reserved in the yarn guiding pipe, and preparation is made for normal starting next time.

Description

technical field [0001] The invention relates to the technical field of power-off devices, in particular to a power-off and yarn retention device for rotor spinning. Background technique [0002] The rotor spinning machine is composed of left and right rotor motors, left and right carding motors, left and right yarn drawing motors, left and right winding motors, process fans, and trash removal fans. In the prior art, in the case of a sudden power failure, the yarn of each spindle will break when the motor loses power, which will cause the workload of the joint when the worker starts up again. Contents of the invention [0003] In order to comprehensively solve the above-mentioned problems, especially for the deficiencies in the prior art, the present invention provides a power-off yarn retention device for rotor spinning, which can fully solve the above-mentioned problems. [0004] To achieve the above object, the present invention adopts the following technical means: ...
