In the ink production process, it is often necessary to mix powdered and liquid raw materials, such as pigment powder and additives. However, the initial size of the powder raw materials used in ink production is often large, ranging from 100-300μm, which cannot meet the requirements of direct processing and mixing. It needs to be further ground to less than 30μm before mixing with the additives. Therefore, the powder raw materials need to be ground and refined first. During this process, existing technologies will cause powder to be blown up, which is not environmentally friendly, has certain health hazards to employees, and is not efficient.

[0022] Furthermore, the crushing mechanism includes a first turntable 250 and a first shearing net 260, the first turntable 250 is connected to the end of the first drive shaft 240, the first shearing net 260 is arranged at the rear end of the first mixing body 200, and a first raised disk 253 is provided in the middle of the first turntable 250, the first raised disk 253 corresponds to the inside of the first shearing net 260, and a plurality of first crushing blade heads 251 are provided on the first raised disk 253, and a plurality of second crushing blade heads 252 are provided on the first turntable 250, and the second crushing blade heads 252 correspond to the outside of the first shearing net 260.

[0023] Furthermore, a first split ring is provided on the inner side of the first intermediate wall 220, the first split ring corresponds to the rear end of the second crushing cutter head 252, the first liquid inlet pipe 222 corresponds to the rear end of the first split ring, and the first liquid storage tank 221 corresponds to the front end of the first split ring.

[0024] Furthermore, the first shearing net 260 is disposed at the front end of the first rear cover 210 . The first shearing net 260 is arranged in a ring shape and is provided with a plurality of first dispersed inclined holes 261 .

[0025] A method for using an environmentally friendly powder-liquid mixing feeding pump comprises the following steps: Step S1: Connect the first liquid inlet pipe 222 and the first powder inlet pipe 211 to the feed source, and control the feeding speed of the liquid raw material and the powder raw material according to the ratio. The powder raw material is fed into the first shearing net 260, and the liquid raw material is fed into the first installation cavity. Step S2: Starting the first high-speed motor 100 at a speed of more than 2900 rpm, the first drive shaft 240 drives the first turntable 250 to rotate, and the first crushing blade 251 crushes the powder material inside the first shearing net 260 from the original 100-300 μm to less than 30 μm, and fully mixes it with the liquid material; Step S3: The second crushing blade 252 cooperates with the first split ring to form a negative pressure space in the pump body, pushing the mixture of the crushed powder and the liquid raw material to the first liquid outlet pipe to complete the feeding.

[0026] Working Principle: First, connect the first liquid inlet pipe 222 and the first powder inlet pipe 211 to ensure the feed connection, and control the switch to confirm that the feed rate of the liquid raw material and the powder raw material meets the required ratio. The powder raw material directly enters the space between the first shearing net 260 and the first crushing head 251 through the first powder inlet pipe 211, while the liquid raw material can flow through the first liquid inlet pipe 222 to fill the first installation cavity. The first high-speed motor 100 drives the first turntable 250 to rotate at a speed exceeding 2900 rpm, not only driving the high-speed mixing of the liquid and powder materials within the first mounting chamber, but also enabling the first and second crushing heads 251, 252, in conjunction with the first shearing net 260, to pulverize the powder materials, reducing the original 100-300 μm powder materials to less than 30 μm. The first shearing net 260, by providing the first dispersing oblique holes 261, not only disperses the powder and liquid materials but also achieves a certain degree of crushing effect, thereby enhancing the pulverization of the powder materials. The second crushing head 252 then cooperates with the first splitting ring to create a negative pressure space within the pump body, extracting the mixed liquid and pumping it out through the first liquid storage tank 221. In other words, the second crushing head 252 not only crushes the powder materials but also serves as a pump impeller. That is, the present application simultaneously achieves both the crushing and mixing functions, eliminating the need to first crush the powder and then mix it with the liquid raw material. This avoids separate crushing processes, eliminating the need for dust to be generated in the production workshop. This is more environmentally friendly, more efficient, and provides ideal and reliable results. It is worth noting that the first high-speed motor 100 is enclosed in a protective housing, and the first mixing body 200 is fixed to the protective housing (which can also be another supporting structure), meaning that the first mixing body 200 does not rotate. Furthermore, this application focuses on the structural design that simultaneously achieves both the crushing and mixing functions, namely, the reinforcement ribs and sealing connection arrangements of the first mixing body 200, which can be achieved using conventional technical means. The structure and materials of the first crushing blade 251 and the second crushing blade 252 can be achieved using conventional technical means. It is only necessary that the blades of the first crushing blade 251 and the second crushing blade 252 are both positioned toward the first shearing net 260 to ensure the crushing effect of the powder raw material.

[0027] It is worth mentioning that the technical features such as the first high-speed motor 100 involved in the patent application of the present invention should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional means in the field, and should not be regarded as the inventive point of the patent of the present invention. The patent of the present invention will not be further elaborated.

[0028] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
