Abstract
A synchronous delivery control device for powder feeding of flux-cored wires comprises a drive motor, a driven motor, a drive motor speed adjustor, a driven motor speed adjustor, a central processing unit, a first analog-to-digital conversion circuit, a second analog-to-digital conversion, a first drive circuit and a second drive circuit. The drive motor and the driven motor are electromagnetic speed adjusting motors. Compared with the prior art, the device has the advantages of being reasonable in design, simple in circuit structure, capable of guaranteeing synchronous accuracy during stable operation, starting and stopping and speed rising and dropping, high in anti-interference and reliable in action. By means of the control device, the filling rate of powder in steel tapes is uniform, and the production quality of flux-cored wires is guaranteed.
Description
Technical field
The utility model relates to technical field of automatic control, is specifically related to the synchronous transport control setup that a kind of flux-cored wire adds medicinal powder.
Background technology
At present, domestic in the equipment of processing medicine wire bond silk, its powder adding device generally all is to adopt mechanically operated mode, drive the main shaft of roll and powder adding device respectively by two motors, realize roll and add powder realizing simultaneously, but because employing is that two motors drive respectively, starting, stopping and the speed rise and fall stage, then be difficult to guarantee synchronization accuracy, like this can be because two motors can not be realized synchronized operation, make that the filling rate of powder in steel band can not be even, influenced the quality of medicinal powder welding wire like this.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, the synchronous transport control setup that provides a kind of flux-cored wire to add medicinal powder.
Its technical scheme is: comprise initiatively motor, slave motor, active machine governor, slave motor governor, central process unit, first analog to digital conversion circuit, second analog to digital conversion circuit, first driving circuit and second driving circuit, described active motor and slave motor are electromagnetic adjustable speed motor.The end that tests the speed of described active motor is connected with an input end of central process unit by first analog to digital conversion circuit, the end that tests the speed of described slave motor is connected with another input end of central process unit by second analog to digital conversion circuit, one mouth of central process unit is connected by the control end of first driving circuit with the active machine governor, initiatively the mouth of machine governor is connected with the excitation coil of active motor, another mouth of central process unit is connected by the control end of second driving circuit with the slave motor governor, and the mouth of slave motor governor is connected with the excitation coil of slave motor.
Wherein, described central process unit is Programmable Logic Controller or single chip circuit.
The utility model has the following advantages compared with prior art: reasonable in design, circuit structure is simple, it can be in smooth operation and startup, stop and the speed rise and fall stage all can guarantee synchronization accuracy, and strong interference immunity, reliable in action.Make that the filling rate of powder in steel band is even, guaranteed the quality of production of medicinal powder welding wire.
