Description
Technical Field
The utility model relates to a construction process of polymer fluid equipment, in particular to a circuit control system for freely converting the discharge amount of equipment according to process requirements.
Background
The general polymer and fluid mechanical equipment is divided into high-pressure spraying equipment and low-pressure pouring and pouring equipment. The general discharge amount control of quantitative pouring and filling equipment is more accurate: the main technical key point is that the timing work control is relatively accurate (the discharge quantity is equal to the rated discharge quantity in the rated time). And high-pressure spraying equipment is generally used for large-area spraying construction.
Because the process quality and the cost are important factors considered by a construction party in construction. In terms of process quality, high-pressure spraying equipment and quantitative filling equipment respectively have the following characteristics: the high-pressure spraying equipment can fully and uniformly mix raw materials due to the high working pressure, so that the construction efficiency is greatly improved. However, the device has no precise quantitative discharging function device, and when the device is used as a pouring device, the device can only be operated by depending on the experience of a spray gun operator, which cannot be accurately controlled, and wastes some raw materials more or less; similarly, the low-pressure quantitative equipment is regarded as a reliable helper by the process demanders in the filling industry due to accurate discharge. When a customer of a quantitative casting device occasionally needs a large-area spraying construction, the process requirement of high-quality spraying cannot be met due to pressure and the like. In summary, the incompatibility of the high pressure spraying equipment and the low pressure filling equipment is highlighted, and the respective purchase of the above two different equipments is likely to cause the waste of capital.

An N line port of a coil of the time relay 7 is connected to an N line of an external power supply AC220V, an L line port of the coil of the time relay 7 is connected to a normally-open end 1-6 of a first normally-open point of the three-way relay 1, and an L line of the external power supply AC220V is connected to a common end 1-1 of the first normally-open point of the three-way relay 1; the other end 7-2 of the normally-open point of the time relay is connected to the normally-open end 1-2 of the second normally-open point of the three-way relay 1, the common end 1-3 of the second normally-open point of the three-way relay is connected to the negative electrode of the pneumatic electromagnetic valve 5, and the normally-open end 2-2 of the normally-open point of the two-way relay 2 is also connected to the negative electrode of the pneumatic electromagnetic valve. The anode of the working indicator light 8 is connected with the anode of the power supply 6, and the cathode of the working indicator light 8 is respectively connected with the common end 1-3 of the second normally-open point of the three-way relay and the normally-open end 2-2 of the normally-open point of the two-way relay. Namely, the 1-3 end points and the 1-5 end points in the three-way relay 1, the 2-2 end points of the two-way relay 2, the working indicator light 8 and the pneumatic solenoid valve 5 are in parallel connection.
The working principle of the embodiment is as follows:
firstly, an automatic quantitative mode, the working basis is as follows: quantitative discharge = discharge per unit time working time.
1.1, when the equipment needs the 'automatic quantitative mode', firstly, the double-control change-over switch 3 is switched to the automatic mode state, so that the 3-0 end point is communicated with the 3-1 end point. And then the normally open gun handle switch 9 is pressed and closed without loosening, namely the 9-1 end point is communicated with the 9-2 end point, so that the output end 3-1 end point of the double-control change-over switch 3 is communicated with the negative electrode 6-2 end point of the power supply 6, and the electromagnetic coil of the three-way relay 1 works, so that the 1-1 end point of the three-way relay 1 is communicated with the 1-6 end point, the 1-2 end point is communicated with the 1-3 end point, and the 1-4 end point is communicated with the 1-5 end point.
1.2, because the 1-1 end point and the 1-6 end point of the three-way relay 1 are communicated, an external AC220V power supply enables the magnetic coil of the AV220V time relay 7 to work, the magnetic coil controls the normally open switch between the internal 7-1 end point and the 7-2 end point to be switched on, and the negative pole line of the power supply 6 is switched on with the 1-2 end point of the three-way relay 1;
1.3, because of the work of the magnetic coil of the three-way relay 1, the 1-2 end points inside the three-way relay 1 are communicated with the 1-3 end points, and because of the parallel connection relationship among the 1-3 end points, the 1-5 end points, the 2-2 end points of the two-way relay 2, the work indicator light 8 and the pneumatic solenoid valve 5, when the magnetic coil of the three-way relay 1 works, the inside is controlled by the magnetic coil to be communicated, so that the AV220V time relay 7, the work indicator light 8 and the pneumatic solenoid valve 5 all work because corresponding work electric energy is obtained. And the pneumatic lance also starts to operate under the control of the pneumatic solenoid valve 5. And the 2-2 end point and the 2-1 end point of the two-way relay 2 are normally opened and disconnected, so the control work is not involved.
1.4, the normally open gun handle switch 9 is pressed until the set working time of the AV220V time relay 7 is zero, namely the internal part of the AV220V time relay 7 is disconnected from the 7-1 end point and the 7-2 end point by the control switch 7-1, namely the related working indicator lamp 8 and the negative pole line of the power supply 6 of the pneumatic electromagnetic valve 5 are disconnected to stop working, and the pneumatic spray gun controlled by the pneumatic electromagnetic valve 5 also stops working.
Overview the automatically controlled process: the double-control change-over switch 3 is switched to an automatic mode state, the normally-open gun handle switch 9 is pressed to be closed and not loosened, the AV220V time relay 7 starts countdown work of set time, meanwhile, the work indicator light 8 is turned on, the pneumatic electromagnetic valve 5 works, and the pneumatic spray gun starts to work. When the working time set by the AV220V time relay 7 stops and returns to zero, the working indicator light 8 is turned off, the pneumatic electromagnetic valve 5 stops working, and the pneumatic spray gun stops working.
Two, manual non-quantitative mode
2.1, when the equipment needs the manual mode, the double-control change-over switch 3 is switched to the manual mode state, namely the 3-0 end point is communicated with the 3-2 end point. The normally open gun handle switch 9 is pressed, namely, the end 9-1 is communicated with the end 9-2, the end 3-2 of the output end of the double-control change-over switch 3 is communicated with the negative electrode of the power supply 6, namely, the electromagnetic coils of the two paths of relays 2 work, so that the normally open end 2-1 in the two paths of relays 2 is communicated with the end 2-2, and the work indicator lamp 8 and the negative electrode line of the pneumatic electromagnetic valve 5 are communicated with the negative electrode of the power supply 6. The work indicator lamp 8 and the pneumatic solenoid valve 5 work due to the working current of the power supply 6, and the pneumatic spray gun starts to work under the control of the pneumatic solenoid valve 5. The spraying working state of the equipment is achieved.
2.2, in a manual mode, the normally-open gun handle switch 9 is released at any time, namely the 9-1 end point is disconnected with the 9-2 end point, so that the negative pole line of the electromagnetic coil of the two-way relay 2 cannot work due to disconnection, the 2-1 end point and the 2-2 end point in the two-way relay 2 are disconnected, and the working indicator light 8 and the working power supply negative pole line of the pneumatic electromagnetic valve 5 are disconnected. The controlled pneumatic spray gun will also stop working, thus stopping the spraying work of the equipment.
Overview of the non-quantitatively controlled process: the double-control change-over switch 3 is switched to a manual mode state, the normally open gun handle switch 9 is closed, the two-way relay 2 works, meanwhile, the working indicator light 8 is turned on, the pneumatic electromagnetic valve 5 works, and the pneumatic spray gun starts to work. When the normally open gun handle switch 9 is released (disconnected), the two-way relay 2 stops working, the controlled working indicator light 8 is turned off, the pneumatic electromagnetic valve 5 stops working, and the pneumatic spray gun stops working.
Example 2
In this embodiment, as shown in fig. 2, the connection line between the gun handle switch-2 end point and the gun handle switch-1 end point is added, so that the gun handle switch 9 in the automatic quantifying mode is upgraded to the self-locking state. The principle is as follows: under the automatic mode state of the double-control change-over switch 3, the 3-0 end point is communicated with the 3-1 end point, the normally open gun handle switch 9 is immediately released after being pressed down, and because the magnetic coil of the three-way relay 1 works at the moment when the normally open gun handle switch 9 is switched on, the 1-2 end point and the 1-3 end point in the relay are communicated, and the 1-4 end point and the 1-5 end point in the relay are communicated; and because of the parallel connection relationship among the 1-3 end points, the 1-5 end points, the 2-2 end points of the two-way relay, the working indicator lamp 8 and the pneumatic electromagnetic valve 5 in the three-way relay 1, when the magnetic coil of the three-way relay 1 works, the 1-1 end point is communicated with the 1-6 end point, the 1-2 end point is communicated with the 1-3 end point, and the 1-4 end point is communicated with the 1-5 end point. Therefore, the AV220V time relay 7, the work indicator light 8 and the pneumatic solenoid valve 5 all work due to the corresponding work electric energy. And the communication between the 1-4 end point and the 1-5 end point enables the 9-2 end point to be repeatedly communicated with the negative pole line of the power supply. Therefore, even if the normally-open gun handle switch 9 is pressed and then disconnected, the magnetic coil of the three-way relay 1 still obtains another negative pole line after the 9-1 end point and the 9-2 end point are disconnected, and the line enables the power supply of the magnetic coil of the three-way relay 1 not to be interrupted and presents a 'circulation' state and a 'self-locking' state. This state continues until the set working time of the AV220V time relay 7 is stopped and returns to zero, that is, the AV220V time relay 7 is disconnected from the 7-1 terminal and the 7-2 terminal of the controlled switch, and then the state is finished. As the time of the working time set by the AV220V time relay 7 is reset to zero, the working indicator lamp 8 is turned off, the pneumatic solenoid valve 5 is stopped, and the pneumatic spray gun is also stopped.
The self-locking working mode can lead an operator to immediately loosen the pressing force of the fingers after pressing the normally open gun handle switch 9, can relieve the fatigue degree of the palm caused by gripping, and can effectively avoid the occurrence of spray gun stop accidents caused by the unintended hand loosening operation of the operator.
The system of the utility model is characterized in that:
1. the working pressure of the equipment is properly adjusted by switching and replacing two simple components, namely a spray gun cap and a gun core, of the spray gun through an automatic quantitative mode/a manual non-quantitative mode.
2. In the automatic quantitative mode, the discharging working time is set, the gun handle switch 9 is closed, and the pneumatic spray gun starts to work. And after the set time is reached, the spray gun automatically stops discharging. Is suitable for the shaping, quantifying and pouring process. Saves raw materials and is simple to operate.
3. Under the manual non-quantitative mode, the discharge time can be freely and flexibly controlled, and spot shooting and large-area spraying can be easily completed. Is suitable for spraying process.
Due to the single conduction characteristic of the double-control change-over switch, whether the quantitative mode or the manual mode is determined, only one relay can work between the three-way relay 1 and the two-way relay 2. When one relay works, the other relay is controlled to be in an open circuit, and the working mode of the equipment cannot be generated or influenced.
The foregoing description is only for the basic principle and the preferred embodiments of the present invention, and modifications and substitutions by those skilled in the art are included in the scope of the present invention.
