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 ...

Embodiment Construction

[0015] The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

[0016] A swing frequency control device for a groove drum frequency converter of a texturing machine, comprising a micro-processing chip 1, a communication interface 2, an intermediate relay 3 and a groove drum frequency converter 4. The microprocessing chip 1 is connected to the tank inverter 4 through the communication interface 2, and the microprocessing chip 1 is connected to the tank inverter 4 through the intermediate relay 3 at the same time, and the microprocessing chip 1 sends a signal to the coil of the intermediate relay 3 to control the contacts of the intermediate relay 3 working status.

[0017] Such as figure 1 As shown, the micro-processing chip 1 is based on the motion mathematical model of the drum frequency converter 4 ( figure 2 ), regularly calculate the frequency value of the drum inverter 4, and send the freque...
