The water supply unit 11 includes a water tub 110 and a water supply pipe 111, and a second filter head 112 provided at an inlet end of the water supply pipe 111.
The first filter head 102 and the second filter head 112 are respectively provided with a filter screen, and can send metal chips or particles to be intercepted, so that the chips in the cutting fluid are prevented from causing damage to the surface of the product.
And the proportioning unit 12 comprises a proportioning valve 120 respectively communicated with the stock solution supply pipe 101 and the water supply pipe 111, and a concentration online measuring instrument 121 arranged on a liquid outlet pipe g of the proportioning valve 120.
The proportioning valve 120 includes a valve body a having a mixing chamber, and a first flow control valve b and a second flow control valve c respectively disposed on the stock solution supply pipe 101 and the water supply pipe 111, wherein the first flow control valve b and the second flow control valve c are respectively communicated with the online concentration measuring instrument 121, and the flow rates of the liquids in the first flow control valve b and the second flow control valve c can be adjusted according to the detection result of the online concentration measuring instrument 121.
The first flow control valve b and the second flow control valve c are both solenoid valves. Thereby facilitating the control of the flow.
In this example, when the first flow control valve b and the second flow control valve c are adjusted, one of the flow rates of the liquid passing through the first flow control valve b and the second flow control valve c increases, and the other flow rate decreases.
Further, in the two solenoid valves, the flow rate increase amount and the flow rate decrease amount of the passing liquid are equal.
Therefore, on the premise of ensuring that the flow of the liquid supply pump is not changed, the concentration can be adjusted by changing the first flow control valve and the second flow control valve so as to meet the requirement of cutting equipment.

Similarly, the stock solution barrel 100 and the water barrel 110 are respectively provided with an upper limit water level sensor f communicated with the liquid adding pump, and when the liquid levels in the stock solution barrel 100 and the water barrel 110 are higher than the upper limit water level sensors, the liquid adding pump stops adding liquid. So as to prevent the liquid in the stock solution barrel and the water barrel from being added excessively.
And the liquid supply pump 13 is arranged on the liquid outlet pipeline g and is used for pumping the cutting liquid stock solution and the water to the valve body a according to the flow rate respectively and then pumping to the required cutting equipment q.

In this way, the proportioning liquid of the automatic cutting fluid proportioning device 1 flows to the liquid storage barrel 3 to be stored by opening the third control valve 7; when the third control valve 7 is closed and the fourth control valve 8 is opened, the proportioning fluid flows directly to the cutting device q.
Therefore, the mixed cutting fluid may be supplied directly to the cutting machine q, or may be stored in the liquid storage tank 3 and then sent to the cutting machine q by the liquid sending pump 5. The main purpose of the liquid feed pump 5 is to ensure that the liquid is fed to each cutting device q at a constant pressure by the liquid feed pipe 2 with the aid of the pressurization of the liquid feed pump 5 because the liquid pressure is insufficient when one liquid feed pump 13 simultaneously feeds liquid to a plurality of cutting devices q, and thus flushing is difficult to achieve. As to how to implement, a PLC controller, a pipeline pressure tester, which is commonly used in the art, may be used, wherein the PLC controller controls the start and stop of the liquid feeding pump 5, which will not be described in detail herein.
Meanwhile, in this example, the liquid storage barrel 3 may be correspondingly provided with an upper limit sensor and a lower limit sensor, once the liquid level inside the liquid storage barrel 3 is lower than the lower limit sensor, the automatic cutting fluid proportioning device 1 automatically performs proportioning and supplies liquid to the liquid storage barrel 3 until the liquid level inside the liquid storage barrel 3 submerges the upper limit sensor, and the automatic cutting fluid proportioning device 1 may stop supplying proportioning liquid.
The present invention has been described in detail, but the present invention is not limited to the above-described embodiments. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
