Abstract
The utility model belongs to the field of textile machinery, and particularly relates to a yarn spreading control device of a stitch-knitting machine chopping component. The yarn spreading control device of the stitch-knitting chopping component is characterized by comprising a PLC (programmable logic controller) playing a role of controlling, wherein the PLC is connected to a driving controller. The PLC is further connected to a frequency converter, and the frequency converter is connected with a three-phase alternating current motor. The yarn spreading control device provided by the utility model can effectively control the yarn spreading speed of the three-phase alternating current motor, enable yarns to spread on a supporting cloth uniformly, and improve the quality of products knitted by a stitch-knitting machine.
Description
Technical field
The utility model belongs to field of textile machinery, particularly the control device of the loose yarn of the chopped parts of a kind of knit-stitch machine.
Background technology
The user was at the chopped loose yarn of using of knit-stitch machine in the past, was directly by an Electric Machine Control, and bad speed governing makes loose yarn skewness on Tobe, and product quality is very poor after loop bonding.
Summary of the invention
For the deficiencies in the prior art, the utility model has related to a kind of loose yarn control device that adopts the Frequency Converter Control three phase alternating current motor, the loose yarn speed that it can effectively control three phase alternating current motor can be evenly scattered on the Tobe loose yarn, has improved the quality of the rear product of knit-stitch machine braiding.
The utility model is achieved through the following technical solutions:
The control device of the loose yarn of the chopped parts of knit-stitch machine, it is characterized in that: the PLC controller that comprises its control action, described PLC controller is connected with driving governor, and described PLC controller also is connected with frequency converter, and described frequency converter is connected with three phase alternating current motor.
Described driving governor comprises the start button that starts control that rises that is connected with the PLC controller, and a stop button that stops to control that is connected with the PLC controller.
In sum, the utility model is by changing the control mode of motor, adopt the PLC controller to control frequency converter, the rotation of Frequency Converter Control three phase alternating current motor, realize adjustableization of three phase alternating current motor rotating speed, can according to the needs of technique, adjust the operating state of frequency converter by the PLC controller, be laid on the Tobe thereby the chopped loose yarn that gets off can be scattered uniformly, improved after the knit-stitch machine loop bonding after the quality of product.
Description of drawings
Fig. 1 is schematic block diagram of the present utility model;
1 is stop button among the figure, and 2 is start button, and 3 is the PLC controller, and 4 is frequency converter, and 5 is three phase alternating current motor.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The control device of the loose yarn of the chopped parts of knit-stitch machine as shown in Figure 1, it is characterized in that: the PLC controller 3 that comprises its control action, described PLC controller 3 is connected with driving governor, and described PLC controller also is connected with frequency converter 4, and described frequency converter 4 is connected with three phase alternating current motor 5.
Described driving governor comprises the start button 2 that starts control that rises that is connected with the PLC controller, and a stop button 1 that stops to control that is connected with the PLC controller.
The course of work of the present utility model:
After start button is pressed, the PLC controller will output signal to frequency converter, make frequency converter be in running status, control the speed of service of three phase alternating current motor, and the speed of motor can be adjusted by frequency converter according to arts demand, and after stop button was pressed, the PLC controller will output signal to frequency converter, make frequency converter be in halted state, thereby make three phase alternating current motor be in halted state.
In sum, the utility model is by changing the control mode of motor, adopt the PLC controller to control frequency converter, the rotation of Frequency Converter Control three phase alternating current motor, realize adjustableization of three phase alternating current motor rotating speed, can according to the needs of technique, adjust the operating state of frequency converter by the PLC controller, be laid on the Tobe thereby the chopped loose yarn that gets off can be scattered uniformly, improved after the knit-stitch machine loop bonding after the quality of product.
Claims (2)
