[0019] The interior of the stirring shaft 4 is provided with a cavity 5, which is designed to reduce the overall weight of the shaft body, thereby reducing the energy consumption of the motor 3 when driving the shaft body to rotate, achieving the effect of energy saving; at the same time, the collision and shear frequency between the medium and the material is increased, greatly improving the grinding efficiency; the scraping and knocking assembly includes a scraping box 6 fixedly connected to the surface of the stirring shaft 4, which can fix the scraper 7 and the spring 9, and at the same time provide installation space and a range of movement for the scraper 7, ensuring that the scraper 7 can smoothly complete the scraping action and the action of knocking the hitting plate 12 during rotation with the stirring shaft 4; the inner wall of the scraping box 6 is slidably connected with the scraper 7 which is in close contact with the inner wall of the stirring cylinder 2, and the scraper 7 is always in close contact with the inner wall of the stirring cylinder 2 under the elastic pushing force of the spring 9, which can scrape off various residual materials attached to the cylinder wall, avoiding waste of raw materials and improving the utilization rate of materials; the arc surface of the scraper 7 is adapted to the curvature of the inner wall of the stirring cylinder 2, ensuring the fit degree and maximizing the coverage of the cylinder wall surface without leaving any scraping dead angle; and the scraper 7 made of tungsten carbide has strong hardness and wear resistance, and at the same time has excellent chemical inertness, which can withstand the long-term erosion of various solvents in the ink, prolonging the service life of the scraper 7 and reducing the downtime caused by replacing the scraper 7, ensuring the continuous operation of the equipment.

[0020] The side surface of the scraper 7 in contact with the inner wall of the stirring cylinder 2 is arc-shaped, and the scraper 7 is a tungsten carbide scraper. The inner side wall of the scraper 7 is fixedly connected with a limiting plate 8, which can effectively limit the sliding range of the scraper 7 and prevent the scraper 7 from coming out of the scraping box 6 during movement. At the same time, the limiting block 17 can also transmit the elastic force of the spring 9 to the scraper 7, ensuring that all parts of the scraper 7 can maintain stable contact with the cylinder wall. The interior of the scraping box 6 is provided with a plurality of springs 9 made of high-quality elastic material, which can always keep the scraper 7 in close contact with the inner wall of the stirring cylinder 2 through continuous and stable elastic pushing force. Whether the scraper 7 is slightly worn after long-term use or the inner wall of the stirring cylinder 2 is slightly uneven, the spring 9 can adjust the elastic force in time to ensure that the scraping effect of the scraper 7 is not affected and the cylinder wall is clean. One end of the spring 9 is fixedly connected to one side of the inner wall of the scraping box 6, and the other end of the spring 9 is fixedly connected to one side of the limiting plate 8, ensuring the transmission of the elastic force. The top of the stirring cylinder 2 is fixedly connected with a feeding pipe 10, which is a channel for the ink raw materials to enter the stirring cylinder 2, ensuring that the raw materials enter the grinding space smoothly. At the same time, the vibration of the vibration plate 14 in the feeding pipe 10 when knocking effectively prevents the pipe wall from being blocked by materials with high viscosity or containing particulate impurities, ensuring the smoothness of the feeding process and providing protection for the continuous production of the equipment.

[0021] The inner wall of the feeding pipe 10 is rotationally connected with a cross shaft 11, which can swing flexibly when the hitting plate 12 is hit, accurately transmitting the reciprocating movement of the hitting plate 12 to the hitting ball 13, realizing effective power transmission from bottom to top, and ensuring the operation of the anti-blocking vibration mechanism of the feeding pipe 10; the bottom end of the cross shaft 11 is fixedly connected with the hitting plate 12, which will swing reciprocally under the intermittent impact of the rotating scraper 7, and such swinging drives the cross shaft 11 to rotate, providing stable driving force for the movement of the cross shaft 11; the top of the cross shaft 11 is fixedly connected with the hitting ball 13, which swings left and right with the rotation of the cross shaft 11, continuously hitting the vibration piece 14 in the movement process, and ensuring the anti-blocking vibration effect; the inner wall of the feeding pipe 10 is rotationally connected with two vibration pieces 14 which can contact the hitting ball 13, which will swing reciprocally at a certain angle with the connecting point of the feeding pipe 10 as the axis after being hit by the hitting ball 13, and the end of the vibration piece 14 will continuously knock the inner wall of the feeding pipe 10 in the rotating process, causing the feeding pipe 10 to vibrate continuously. Such vibration can effectively break the adhesion of the material on the pipe wall, prevent the material from being blocked due to high viscosity or containing particulate impurities, and ensure the smoothness of feeding without frequent manual cleaning.

[0022] The outer side of the vibration piece 14 is provided with a chute 15 which is matched in shape and size with the slide rod 16, providing an accurate sliding path for the slide rod 16; the inner wall of the chute 15 is slidingly connected with the slide rod 16, which can convert the reciprocating rotation of the vibration piece 14 into linear sliding of itself, and further drive the limiting block 17 to press the spring 19; the slide rod 16 is provided in the pipe wall of the feeding pipe 10 and slidingly matched with the pipe wall, ensuring the stability and flexibility of the slide rod 16 in the sliding process; the outer side of the slide rod 16 is fixedly connected with the limiting block 17 which limits the position of the spring 19 to prevent the spring 19 from deviating in the stretching and contracting process; the outer side of the slide rod 16 is slidingly connected with the gasket 18 fixed to the outer wall of the feeding pipe 10, which provides stable support for the spring 19, so that the spring 19 will not shake in the working process; one end of the gasket 18 is fixedly connected with the spring 19, which will contract and store energy after being pressed by the limiting block 17, and will quickly rebound when the external force disappears, generating a spring force to quickly reset the vibration piece 14 so as to be hit by the hitting ball 13 again, thereby maintaining a stable vibration frequency and ensuring the continuity and effectiveness of the anti-blocking vibration.

[0023] The other end of the spring 2 is fixedly connected to one side of the limiting block 17, and the elastic force of the spring 2 acts on the limiting block 17, and then is transmitted to the slide rod 16 and the vibrating reed 14, so that the transmission of the elastic force is ensured. The left side of the stirring cylinder 2 is fixedly connected with a discharge pipe 20, the discharge pipe 20 is a channel for discharging the ink material after grinding, and the qualified ink after grinding is smoothly conveyed to the subsequent process, such as filtering, storage and the like, so as to ensure the coherence of the production process; the inner wall of the discharge pipe 20 is fixedly connected with a filter screen 21 for intercepting the grinding medium, the filter screen 21 is made of high-precision filtering material, can effectively intercept the grinding medium, so that the grinding medium remains in the stirring cylinder 2 to continue to participate in the grinding process, and the recycling of the grinding medium is realized; the discharge pipe 20 is fixedly installed with a valve 22 for controlling the discharge, the valve 22 can accurately control the opening and closing of the discharge pipe 20, and by adjusting the opening degree of the valve 22, the discharge speed and the discharge amount of the material can also be flexibly controlled, and the operator can adjust the discharging state at any time according to the production demand and the processing capacity of the subsequent process, so as to facilitate the regulation and control of the production operation.

[0024] Working principle: when the ink raw material to be ground is added, the material enters the inside of the stirring cylinder 2 from the channel at the top end of the feeding pipe 10. At this time, the motor 3 in the machine body 1 is started, and the motor 3 as a power source starts to operate, and its output shaft directly transmits power to the stirring shaft 4, driving the stirring shaft 4 to rotate at high speed in the stirring cylinder 2. The cavity 5 plays an important role in this process. On the one hand, the existence of the cavity 5 significantly reduces the overall weight of the shaft body, so that the motor 3 needs much less energy to drive the shaft body to rotate, achieving the effect of energy saving; on the other hand, the hollow structure of the cavity 5 guides the grinding medium and the material to form a more reasonable circulating state through a unique design - when the stirring shaft 4 rotates at high speed, a significant speed difference is formed between the surface of the shaft body outside the cavity 5 and the grinding medium, prompting the medium to form an orderly spiral motion track around the cavity 5, and the material is also moved under the driving of the medium, enhancing the collision and shearing frequency between the medium and the material, laying a solid foundation for subsequent efficient grinding.

[0025] At the same time when the stirring shaft 4 rotates, the plurality of scraping boxes 6 also rotate synchronously. The scraper 7 is always in close contact with the inner wall of the stirring cylinder 2 under the elastic thrust of the spring 1 9, completely scraping off the residual material adhered to the cylinder wall, avoiding the waste of raw materials and improving the utilization rate of the material. The side surface of the scraper 7 in contact with the inner wall of the stirring cylinder 2 is arc-shaped and made of tungsten carbide material. The arc-shaped design makes it have a higher degree of fit with the cylinder wall, and cooperates with the elastic force of the spring 1 9 to ensure that there is no scraping dead angle in the rotating process, and the tungsten carbide material ensures that the scraper 7 still maintains good wear resistance and chemical stability under the condition of long-term friction with the cylinder wall and contact with various solvents in the ink, prolonging the service life.

[0026] At the same time, the rotating scraper 7 will intermittently knock the beating plate 12, and each impact can give the beating plate 12 an external force, so that the cross shaft 11 rotates inside the feeding pipe 10 with the connecting point of the feeding pipe 10 as the axis, and further drives the beating ball 13 to rotate. The beating ball 13 will continuously hit the vibrating piece 14 during rotation, and under the action of the impact force, the vibrating piece 14 reciprocatingly rotates at a certain angle with the connecting point of the feeding pipe 10 as the axis, and the end continuously knocks the inner wall of the feeding pipe 10 during rotation, so that the feeding pipe 10 generates continuous vibration. Such vibration can effectively break the adhesion of the material on the pipe wall, and has good anti-blocking effect on materials that are easily attached to the pipe wall due to high viscosity or containing particulate impurities, without the need for frequent manual cleaning, ensuring smooth feeding and meeting the needs of efficient and sustainable production.

[0027] When the vibrating piece 14 rotates, the slide rod 16 is driven by the slide groove 15 to slide along the wall of the feeding pipe 10. Further, the limiting block 17 is driven to move together, and the spring 2 is squeezed. After being squeezed, the spring 2 is contracted and stored. When the scraper 7 is separated from the beating plate 12 and the impact force of the beating ball 13 on the vibrating piece 14 disappears, the spring 2 will quickly rebound, and the elastic force generated by the spring 2 is transmitted to the vibrating piece 14 through the limiting block 17 and the slide rod 16, assisting the vibrating piece 14 to quickly reset for the next impact, ensuring the continuity and stability of the vibration anti-blocking, so that the feeding pipe 10 is always kept unobstructed.

[0028] After a period of grinding, when the ink material reaches the desired fineness requirement, the operator can open the valve 22 on the discharge pipe 20 to discharge the qualified material along the discharge pipe 20. The filter screen 21 is made of high-precision filtering material, which can effectively intercept the grinding medium, so that the grinding medium remains in the stirring drum 2 to continue participating in the subsequent grinding process, realizing the recycling of the grinding medium, reducing the production cost, and further embodying the sustainable working characteristics of the equipment. The discharged qualified material is conveyed to the subsequent process, such as filtering, storage, etc., to ensure the coherence of the entire production process.
