Abstract
The utility model relates to a drive load transmission circuit structure of an oil press screw. The drive load transmission circuit structure comprises a drive motor, an alternating current input end, a rectification bridge, an MCU and a motor starting and stopping control unit, the drive motor is connected with the alternating current input end through the rectification bridge, the motor starting and stopping control unit comprises a control switch and a motor control input end, the control switch is electrically connected between one terminal of the drive motor and the rectification bridge, and the MCU is connected with the control switch through a motor switch input end. The drive load transmission circuit structure is provided with a motor load detection unit and the motor starting and stopping control unit, due to the fact that the motor load detection unit can detect current values in circuits through current and voltage parameters switched in the alternating current input end to judge the state of the motor, feeding flow of a feeding port can be increased or reduced according to processing of the external MCU, and if the motor is judged to be overloaded, the MCU controls the feeding flow of the feeding port to be reduced, and motor loads are lowered.
Description
Technical field
The utility model belongs to field of household appliances, is specifically related to a kind of Domestic oil press.
Background technology
The plant that oil press can have a grease to peanut, plant etc. is extracted oil, and uses to extract vegetable oil, and meanwhile, oil press can also be processed fruit, to extract its juice.But; in the middle of expressing process, the charging aperture of oil press is because instantaneous charging is when too much; the load that often can run into jack-in-the-box, drive motors is overweight; if in the case; process continues and does not reduce inlet amount; it will cause drive motors electric current excessive and damage motor, damage jack-in-the-box when serious, reduces overall service life.
Summary of the invention
Too much easily make the problems such as the excessive and screw rod life-span reduction of current of electric in order to solve the charging existing in prior art, now redesign a kind of drive circuit control structure of damaging in machine operation process of preventing.
The utility model for the technical scheme that its technical problem of solution adopts is: oil press screw drive load transmission circuit structure, comprise drive motors, ac input end, rectifier bridge, MCU control module and motor on off control unit, described drive motors is connected with described ac input end by rectifier bridge, described motor on off control unit comprises gauge tap and Electric Machine Control input, gauge tap is electrically connected between a terminal and rectifier bridge of drive motors, described MCU control module is connected with described gauge tap by motor switch input.
As further describing above-mentioned oil press screw drive load transmission circuit structure, between described rectifier bridge and ac input end, be connected to motor load detecting unit by a voltage transformation unit, motor load detecting unit comprises that motor load detects output, and described motor load detects output and is connected with MCU control module.
As a kind of preferred version to above-mentioned oil press screw drive load transmission circuit structure, described rectifier bridge is full-wave rectifying circuit.
As further describing above-mentioned oil press screw drive load transmission circuit structure, described motor on off control unit also comprises triode, gauge tap is a relay, and the colelctor electrode of triode is connected with described relay, and base stage is connected with described Electric Machine Control input.
The beneficial effects of the utility model are: be provided with motor load detecting unit, motor on off control unit, because motor load detecting unit can be by the electric current of incoming transport input, voltage parameter detects the current value in circuit, and then judge the state of motor, thereby can be according to the processing of outside MCU, charging aperture is carried out to the increase and decrease of feed rate, if when motor is judged as overload, the charging that MCU controls charging aperture reduces, motor load is reduced, if when motor seriously transships, MCU controls motor on off control unit, disconnect motor circuit a period of time, stop the running of drive motors, excessive and damage with protection current of electric.
Brief description of the drawings
Fig. 1 is circuit structure diagram of the present utility model.
Detailed description of the invention
Referring to Fig. 1, the oil press screw drive load transmission circuit structure that the utility model provides, comprise drive motors M1, ac input end J1, rectifier bridge B1, MCU control module and motor on off control unit, described drive motors M1 is connected with described ac input end J1 by rectifier bridge B1, described motor on off control unit comprises gauge tap K1 and Electric Machine Control input, gauge tap K1 is electrically connected between M1 mono-terminal and rectifier bridge B1 of drive motors, described MCU control module is connected with described gauge tap K1 by motor switch input.
As further describing above-mentioned oil press screw drive load transmission circuit structure, between described rectifier bridge B1 and ac input end J1, be connected to motor load detecting unit by a voltage transformation unit, motor load detecting unit comprises that motor load detects output, and described motor load detects output and is connected with MCU control module.
As a kind of preferred version to above-mentioned oil press screw drive load transmission circuit structure, described rectifier bridge B1 is full-wave rectifying circuit.
As further describing above-mentioned oil press screw drive load transmission circuit structure, described motor on off control unit also comprises triode Q1, gauge tap K1 is a relay, and the colelctor electrode of triode Q1 is connected with described relay, and base stage is connected with described Electric Machine Control input.
Motor load detecting unit is by electric current, the voltage parameter of incoming transport input, can detect motor current value in the line, and then the state that judges motor is (if power of motor is fixed, but when rotating speed is too small, electric current will be excessive, this state will be through conversion, exports motor load to and detects output), and output to MCU control module place and feed back accordingly.If motor is under overload situations, MCU control module will be controlled charging aperture and reduce charging, the load of motor is reduced, in the time that motor is normal, increase and decrease inlet amount according to motor load situation again, if motor is under serious overload situations, MCU control module transfers signals to Electric Machine Control input, and gauge tap is turn-offed to control.
The utility model has more than and is limited to the technical scheme that above-described embodiment provides, and other electronic alarm clocks that the same or similar structure of all employings and the utility model is manufactured, all drop in the utility model protection domain.
