Abstract

The invention mainly discloses a wobble frequency control device of an elasticizer groove drum frequency converter. The control device comprises a micro programming chip, a communication interface, an intermediate relay and a groove drum frequency converter, wherein the micro programming chip is connected with the groove drum frequency converter through the communication interface, and the micro programming chip is connected with the groove drum frequency converter simultaneously through the intermediate relay; and the micro programming chip sends a signal to a coil of the intermediate relay so as to control the working condition of a contact of the intermediate relay. The micro programming chip as an upper computer and a frequency converter perform data exchange uninterruptedly, and the frequency converter can operate according to requirements; the control device provided by the invention has strong anti-interference capability, and can rapidly finish complicated frequency change.

Description

technical field [0001] The invention relates to the technical field of texturing machine manufacturing, in particular to a swing frequency control device for a texturing machine groove barrel frequency converter which uses a single-chip microcomputer to control the frequency change of the frequency converter through a serial communication interface. Background technique [0002] In the field of texturing machine manufacturing, in order to prevent the wires from overlapping and achieve a better unwinding effect, the grooved drum motor needs to be continuously accelerated and decelerated to form a figure 2 In the motion waveform shown, special attention should be paid to the fact that the motor speed of the groove drum does not fluctuate for a long time, which may cause some wires to overlap and affect the unwinding effect of the rear channel of the wire. [0003] Currently, there are generally two options for controlling the movement: [0004] 1. Complete by the function of ...
