Drawings
Fig. 1 is a schematic diagram of a specific embodiment of a sand blasting machine control system of the present invention, wherein the names of the reference symbols are: the device comprises a pressure gauge 1, a sand blasting pressure gauge 2, a QS-knife switch, a KM 1-contactor positive switch, a KM 1A-contactor coil, an L-indicator lamp, an SB 1-inching switch, an SB 2-normally closed shutdown switch, an SB 3-normally open starting switch and a DC-DC power supply.
Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings.
The utility model discloses a sand blasting machine control system, including the gas pitcher to and connect the gas-supply pipe between gas pitcher and sand blasting machine, install the solenoid valve on the gas-supply pipe, the control system still includes solenoid valve control circuit;
the control circuit comprises a inching switch SB1, a contactor positive switch KM1 and a direct-current power supply DC which are connected with an electromagnetic valve coil in series and form a loop, the direct-current power supply is also connected with a contactor control circuit in parallel, and the contactor control circuit comprises a contactor coil KM1A, a normally-open starting switch SB3 and a normally-closed shutdown switch SB2 which are connected in series; the normally-off starting switch is connected with a contactor positive switch in parallel.
The utility model discloses in, the switch switches on when the hand is pressed, and disconnection or opposite switch after the hand loosens, and the state when pressing is the transient state that can not maintain for a long time, and the hand loosens the after-recovery normality.
Before the use, normally-off starting switch SB3 can be pressed first, because normally-closed shutdown switch SB2 is closed at this moment, contactor coil KM1A is conducted with the power supply, the contactor is electrified, all contactor positive switches KM1 are closed, and a contactor positive switch is connected in parallel with the normally-off starting switch, so that even if a person takes off the normally-off starting switch to be disconnected, contactor coil KM1A still maintains the electrified state.
And then controlling a inching switch SB1, wherein the inching switch is a pedal switch in a general preferred embodiment, the inching switch is closed when being pressed down, the solenoid valve coil is electrified, the solenoid valve is closed, and the air tank starts to convey high-pressure air to the sand blasting machine for the operation of the sand blasting machine. The operator repeatedly steps on the pedal, and the gas tank continuously conveys gas. The direct current power supply can adopt a 24V direct current power supply.
A barometer 1 can be arranged on the part of the gas transmission pipe between the gas tank and the electromagnetic valve and used for observing the gas pressure of the gas tank, and a sand blasting pressure gauge 2 can be arranged on the part of the gas transmission pipe between the electromagnetic valve and the sand blasting machine; for observation of the blasting pressure.
Can be in the parallelly connected pilot lamp of contactor coil, the contactor coil gets electric back, and the pilot lamp lights, reminds the operator can begin to operate the inching switch at this moment and carry out the sandblast operation.
The operator stops trampling inching switch SB1, then the solenoid valve coil is not electrified, and the solenoid valve is closed, when needing to shut down, presses normally closed shutdown switch SB2, and contactor coil KM1A loses the electricity, and contactor positive switch KM1 disconnection, although normally closed shutdown switch SB2 resumes the closure after the hand is loosened this moment, but contactor positive switch and normally open start switch SB3 all break off, and the contactor coil maintains the state of losing the electricity, and the solenoid valve coil is connected the disconnection with the power.
Adopt sand blasting machine control system adopts solenoid valve on-off control, simple structure, and the operation is longe-lived, can adopt the direct current battery direct control solenoid valve of lower voltage, and operation process is safer.
In the foregoing, the preferred embodiments of the present invention, if not obviously contradictory or based on a certain preferred embodiment, can be combined and used by any superposition, the specific parameters in the embodiments and examples are only for clearly expressing the utility model verification process of the utility model, and are not used for limiting the patent protection scope of the present invention, the patent protection scope of the present invention is still based on the claims, and all the equivalent structural changes made by the contents of the specification and the drawings of the present invention should be included in the protection scope of the present invention.
