Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a grinding device for ink production. Background Technology

[0002] Printing ink is an essential material used in printing, which transfers patterns and text onto a substrate through printing or inkjet printing. Printing ink consists of main and auxiliary components, which are uniformly mixed and repeatedly rolled to form a viscous, colloidal fluid. It is composed of binders (resins), pigments, fillers, additives, and solvents. It is used in various printing applications, including books, packaging, architectural decoration, and electronic circuit boards. With increasing societal demand, the variety and production volume of printing inks have expanded and grown accordingly.

[0003] In the traditional ink production process, ink materials need to be ground. If the grinding precision does not meet the requirements, the quality of the product will be greatly reduced. The grinding efficiency is low, and the material cannot be ground sufficiently during the grinding process. It often requires multiple grinding to achieve the required particle size, which is time-consuming. In addition, the grinding is not thorough, and some larger particles are easily missed, resulting in uneven particle size of the ground material, which affects subsequent use. Utility Model Content

[0004] In view of this, the present invention provides a grinding device for ink production, which can achieve efficient, rapid and thorough grinding of materials through the grinding mechanism. This solves the problems of traditional ink production, where grinding of ink materials is required, but if the grinding precision is not up to standard, the quality of the product will be greatly reduced. The grinding efficiency is low, the material cannot be fully ground during the grinding process, and multiple grindings are often required to achieve the required particle size, which is time-consuming. Furthermore, the grinding is not thorough, and some larger particles are easily missed, resulting in uneven particle size of the ground material, which affects subsequent use.

[0005] To solve the above-mentioned technical problems, this utility model provides a grinding device for ink production, including a grinding box. Inside the grinding box, a grinding mechanism is rotatably connected to the output shaft of a drive component. The grinding mechanism includes a screen cylinder inside the grinding box, and inside the screen cylinder, a rotating shaft is rotatably connected to the output shaft of the drive component. A grinding auger is located on the outer side of the rotating shaft. Multiple grinding balls that cooperate with the grinding auger are arranged on the inner side wall of the screen cylinder. Multiple filter holes are opened on the side wall of the screen cylinder. The minimum distance between the grinding auger and the grinding balls is less than the diameter of the filter holes. This utility model allows the grinding auger to rotate along with the output shaft of the drive component, cooperating with the grinding balls to achieve efficient grinding of the material inside the screen cylinder. Simultaneously, the ground material that meets the particle size requirements is discharged through the filter holes.

[0023] According to one embodiment of the present invention, such as Figure 1-4As shown, a guide box 300 is also provided inside the grinding box 100. The guide box 300 is located below the screen cylinder 210, and the lower part of the screen cylinder 210 is placed inside the guide box 300.

This utility model can realize the automatic discharge of the ground material through the downwardly inclined guide box 300, making the operation more convenient.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a plurality of discharge holes 101 are provided on the side wall of the grinding box 100 located at the lowest end of the guide box 300. This utility model can realize the efficient discharge and collection of the ground material in the guide box 300 through the discharge holes 101, making the operation more convenient.

[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, a feed hopper 400 is provided on the upper part of the grinding box 100 and is connected to it.

[0028] How to use this utility model:

[0029] First, it should be clarified that the grinding device involved in this utility model is mainly used for grinding various materials. This utility model takes the grinding of graphite particles as an example to explain its working principle and usage method in detail. It should be noted that the grinding device is a horizontal grinding mill, and its driving component is a servo motor, which is connected to the rotating shaft 220 through a coupling. Since the main improvement of this device is in the efficiency of grinding, its specific driving principle will not be described in detail here. The working principle is as follows:

[0030] When the equipment starts, the drive unit (Y132S-4 type three-phase asynchronous motor) begins to work. Its output shaft drives the rotating shaft 220 to rotate through the coupling. The rotating shaft 220 then drives the grinding auger 230 and the grinding sleeve to rotate together. The material to be ground is put into the feed hopper 400. Since the feed hopper 400 has a funnel-shaped structure, the material enters the screen cylinder 210 from the feed port 213 through the connecting channel 500 under the action of gravity.

[0031] Under the rotating conveying action of the grinding auger 230, the material moves along the length of the screen cylinder 210. Simultaneously, the material is subjected to compression, collision, and friction between the grinding auger 230, the grinding sleeve, and the grinding balls 212 on the inner wall of the screen cylinder 210, thus achieving the grinding operation. Since the minimum distance between the grinding auger 230 and the grinding balls 212 is less than the diameter of the filter hole 211, materials with a particle size smaller than the specified size can pass through the filter hole 211 and enter the feed box 300. Materials with a particle size larger than the specified size continue to be repeatedly ground under the conveying action of the grinding auger 230 until the particle size meets the requirements, after which they pass through the filter hole 211 and enter the feed box 300.

[0032] The material entering the feed box 300 is inclined downward along the conveying direction of the grinding auger 230 (inclination angle 15 degrees) due to the bottom inner wall of the feed box 300. Under the action of gravity, it flows towards the discharge hole 101 and is finally discharged from the equipment through the discharge hole 101, completing the entire grinding process.

[0033] The usage method is as follows:

[0034] Before use, check that all parts of the equipment are securely connected and that the drive components are functioning properly to ensure that the equipment is in good condition.

[0035] Pour the material to be ground into the feed hopper 400. Note that the amount of material added should not be too much, so as not to affect the grinding effect.

[0036] Start the drive unit (Y132S-4 type three-phase asynchronous motor) to make the grinding auger 230 start rotating and carry out the grinding operation.

[0037] The material is ground in the screen cylinder 210. The material that meets the particle size requirements enters the feed box 300 through the filter hole 211 and is then discharged through the discharge hole 101. A collection device can be placed below the discharge hole 101 to collect the ground material.

[0038] After all materials have been ground, turn off the drive unit and wait for the equipment to stop rotating completely before cleaning the inside of the equipment for the next use.

[0039] This invention enables efficient, rapid, and thorough grinding of materials via the grinding mechanism 200. It solves the problems of traditional ink production, where grinding of ink materials is necessary, but if the grinding precision is not met, the quality of the product will be greatly reduced. The grinding efficiency is low, and the material cannot be fully ground during the grinding process, often requiring multiple grindings to achieve the required particle size, which is time-consuming. Furthermore, insufficient grinding can lead to the omission of some larger particles, resulting in uneven particle size after grinding, which affects subsequent use.

[0040] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
