An electromagnetic valve 12 is provided on the connecting pipe 11. A transparent plate 24 is embedded in the front side of the mixing barrel 2 to facilitate observation of the state inside the mixing barrel 2. A protective shell 25 is provided at the bottom of the cover plate 4. The drive motor 5 is located inside the protective shell 25 to protect the drive motor 5 from being affected by the external environment.

[0027] When the cutting fluid needs to be mixed and proportioned, first place the placement bucket 10 on the weighing component 9, pour water into one of the placement buckets 10, at this time the weighing component 9 weighs the water and displays the weighing result, then slowly pour the cutting fluid stock solution into the other placement bucket 10, the weighing component 9 continues to weigh the cutting fluid stock solution until the cutting fluid stock solution reaches the required proportion weight, then stops pouring, thereby achieving accurate proportioning and improving the proportioning effect of the cutting fluid, next, open the solenoid valve 12, so that the cutting fluid stock solution and water in the two placement buckets 10 are transported to the inside of the discharge frame 7 through the connecting pipe 11, and then flow into the inside of the mixing barrel 2 through the discharge frame 7, and then start the drive motor 5, the output shaft of the drive motor 5 rotates to drive the mixing paddle 6 to rotate, and the cutting fluid stock solution and water are fully stirred to make them mixed evenly. After the mixing is completed, turn off the drive motor 5, open the valve 3, and discharge the mixed cutting fluid.

[0028] Example 2: Based on Example 1, please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 7 A filter frame 13 is slidingly arranged inside the blanking frame 7, a handle 14 is fixedly connected to the front side of the filter frame 13, a filter screen 15 is embedded inside the filter frame 13, and a magnetic plate 16 is arranged on the front side of the filter frame 13. The magnetic plate 16 is adsorbed on the front side of the blanking frame 7. When the filter frame 13 needs to be cleaned, hold the handle 14, pull the filter frame 13 forward, and take it out from the inside of the blanking frame 7 to clean the filter frame 13.

[0029] When the cutting fluid and water are transported to the inside of the blanking frame 7 , the filter 15 will filter the impurities in the cutting fluid and water, thereby improving the purity of the cutting fluid. The filtered cutting fluid and water then flow into the inside of the mixing barrel 2 .

[0030] See also Figure 1 、 Figure 2 、 Figure 8 and Figure 9 A limit frame 17 is placed on the rear side of the support shell 1, and a sliding plate 18 is provided on the rear side of the support shell 1 by bolt connection.

[0031] After the cutting fluid and water flow into the mixing barrel 2, the servo motor 22 is started, and the output shaft of the servo motor 22 rotates to drive the cam 23 to rotate. When the cam 23 rotates, the support shell 1 is squeezed to move downward, and the sliding plate 18 moves downward and compresses the return spring 20.
