[0046] Combination Figures 1 to 7 As shown, a digital printing ink regulating device includes a tank body 1, a stirring component 2, a gear 3 and a driving component 4.

[0047] A water inlet pipe 11 is fixedly provided on the upper part of the tank body 1, a feeding pipe 12 is fixedly provided on one side of the tank body 1, and a discharge pipe 13 is fixedly provided on the lower part of the tank body 1; a stirring assembly 2 is rotatably provided in the inner cavity of the tank body 1, the top end of the stirring assembly 2 passes through the tank body 1, and extends to the outer fixed sleeve of the tank body 1, and a gear 3 is rotatably provided on the upper part of the tank body 1; a driving assembly 4 is provided on the upper part of the tank body 1, and the driving assembly 4 is transmission-connected with the stirring assembly 2; the driving assembly 4 includes: a driving block 41, a rack 43, a mounting frame 44, a driving member 45, a rotating disk 46 and a driving pin 47. The driving block 41 is slidably arranged on the upper part of the tank body 1, and a slide groove 42 is opened on the driving block 41; the rack 43 is fixedly arranged on the driving block 41, the rack 43 is located on one side of the slide groove 42, and the rack 43 is meshed with the gear 3; the mounting frame 44 is arranged on one side of the tank body 1, and the mounting frame 44 is located on one side of the driving block 41; the driving member 45 is arranged on the mounting frame 44, and the output end of the driving member 45 passes through the mounting frame 44 and is fixedly connected with a rotating disk 46, and the rotating disk 46 is rotatably arranged on the mounting frame 44; the driving pin 47 is fixedly arranged at the edge of the rotating disk 46, and one end of the driving pin 47 is slidably embedded in the slide groove 42.

[0048] Among them, a driving block 41 is slidably arranged on the upper part of the tank body 1, and a rack meshing with the gear 3 is fixedly arranged on the driving block 41, so that the driving block 41 can effectively change the rotation direction of the stirring component 2 while sliding back and forth on the upper part of the tank body 1, thereby achieving the effect that the stirring component 2 can rotate alternately clockwise and counterclockwise. This design method can not only improve the fluidity of the ink, but also make the ink mixing more uniform, thereby improving the efficiency of ink adjustment and mixing; by adopting a driving member 45, a rotating disk 46 and a design method in which the driving pin 47 on the rotating disk 46 is slidably embedded in the slide groove 42, the reciprocating sliding operation effect of the driving block 41 is achieved, the alternating rotation effect of the stirring component 2 is further guaranteed, the working stability of the device is improved, and the degree of automation of the device and the efficiency of ink adjustment are greatly improved.

[0049] During operation, first, the ink to be adjusted is poured into the tank body 1 from the feeding pipe 12, and the corresponding proportion of water is poured into the tank body 1 through the water inlet pipe 11. After the ink is poured into the tank body 1, the required proportion of additives is added from the feeding pipe 12 again, and then the driving member 45 is started to make the rotating disk 46 start to rotate, thereby driving the driving pin 47 to slide back and forth in the slide groove 42, so that the driving block 41 slides back and forth on the upper part of the tank body 1. During this process, since the rack 43 is meshed with the gear 3, when the driving block 41 slides to one side, the stirring component 2 will rotate clockwise; conversely, when the driving block 41 slides to the other side, the stirring component 2 will rotate counterclockwise. This design method realizes the effect that the stirring component 2 can rotate alternately clockwise and counterclockwise, which can not only improve the fluidity of the ink, but also make the ink mixing more uniform, thereby improving the efficiency of ink adjustment and mixing.

[0050] It should be noted that the device also includes a heating mechanism and a control mechanism.

[0051] Combination Figure 1 , Figure 2 and Figure 7 As shown, the upper part of the tank body 1 is detachably mounted with a cover plate 14 by means of screw connection, the upper part of the cover plate 14 is fixedly provided with a water inlet pipe 11, and a guide rail 15 is provided on one side of the water inlet pipe 11; the lower part of the driving block 41 is fixedly provided with a slider 48, and the slider 48 is embedded in the guide rail 15. This design can ensure the stable sliding of the driving block 41 on the upper part of the tank body 1, prevent it from deviating from the track, and ensure the smooth progress of the stirring process. At the same time, the detachable design of the cover plate 14 facilitates the cleaning and maintenance of the inside of the tank body 1.

[0052] To further explain, the driving block 41 is in an L-shaped structure, and the sliding block 48 is consistent with the structure of the guide rail 15 .

[0053] Among them, such a design allows the driving block 41 to have a slide groove 42 thereon for installing and guiding the movement of the driving pin 47 while satisfying the reciprocating sliding. This not only makes full use of the space, but also ensures the compactness and stability of the equipment. The slider 48 is consistent with the structure of the guide rail 15, which can ensure the stable sliding of the driving block 41 on the upper part of the tank body 1, prevent deviation or shaking, and improve the stability of the stirring process. Such a design allows the rack 43 to be fixedly set on one side of the driving block 41 without affecting the installation and operation of other components. At the same time, this also facilitates the good engagement of the rack 43 with the gear 3, so as to realize the clockwise and counterclockwise alternating rotation of the stirring assembly 2.

[0054] To further explain, the driving member 45 is a driving motor.

[0055] Combination Figure 2 and Figure 7 As shown, a water storage chamber 16 is opened in the inner cavity of the tank body 1, and a mixing and stirring chamber 17 is opened at the lower part of the water storage chamber 16. The mixing and stirring chamber 17 is connected to the water storage chamber 16 through a plurality of connecting holes 18. The water inlet pipe 11 is connected to the water storage chamber 16, the feeding pipe 12 is connected to the mixing and stirring chamber 17, and the discharge pipe 13 is connected to the mixing and stirring chamber 17.

[0056] Specifically, the water storage chamber 16 is used to store water to be added, and the water inlet pipe 11 introduces an external water source into the water storage chamber 16. When the ink needs to be adjusted, the ink is added to the mixing and stirring chamber 17 through the feeding pipe 12, and then the water in the water storage chamber 16 flows into the mixing and stirring chamber 17 through the connecting hole 18 to mix with the ink. Since the mixing and stirring chamber 17 is connected to the driving component 4, the driving component 4 can drive the stirring blade to rotate, thereby achieving uniform stirring of the ink and water and ensuring the fluidity of the ink.

[0057] Combination Figure 7 As shown, a nozzle 19 is provided at the connecting hole 18. Specifically, when the water in the water storage chamber 16 flows into the mixing and stirring chamber 17 through the connecting hole 18, if it flows directly, the ink may splash or fail to mix fully with the water due to the strong impact force of the water flow. After the nozzle 19 is provided, the water will pass through the nozzle 19 to form a fine water mist, which can reduce the impact force of the water flow on the ink and increase the contact area between the water and the ink, so that the two can be mixed more evenly and quickly. In addition, the design of the nozzle 19 also helps to control the flow of water, thereby better controlling the viscosity of the ink to meet different printing needs.

[0058] Combination Figure 2 , Figure 3 and Figure 6 As shown, a stirring assembly 2 is rotatably arranged in the mixing and stirring chamber 17, and the stirring assembly 2 includes: a stirring shaft 21, a first stirring rod 22, a second stirring rod 23, a scraper 24 and a spiral stirring rod 25. The stirring shaft 21 is rotatably arranged in the mixing and stirring chamber 17, and the top end of the stirring shaft 21 passes through the water storage chamber 16 and extends to the outside of the tank body 1 and is fixedly sleeved with a gear 3; the first stirring rod 22 is fixedly sleeved on the stirring shaft 21; the second stirring rod 23 is fixedly arranged below the first stirring rod 22; the scraper 24 is fixedly arranged at both ends between the first stirring rod 22 and the second stirring rod 23, and one side of the scraper 24 is in contact with the inner wall of the mixing and stirring chamber 17; the spiral stirring rod 25 is fixedly arranged between the first stirring rod 22 and the second stirring rod 23.

[0059] Among them, the stirring shaft 21 is the main part of the stirring component 2. It rotates under the action of the driving member 45, driving other components to work together. The first stirring rod 22 and the second stirring rod 23 are respectively fixed at different positions of the stirring shaft 21. Through their rotation, the ink and water in the mixing chamber can be fully and evenly stirred. One side of the scraper 24 is in contact with the inner wall of the mixing and stirring chamber 17, so that when the stirring component 2 rotates, the scraper 24 can scrape off the ink attached to the inner wall, so that it can re-participate in the mixing process and improve the mixing efficiency. The spiral stirring rod 25 is fixed between the first stirring rod 22 and the second stirring rod 23. Its spiral shape design helps to push the ink downward or push the ink deposited below upward to flow, so as to avoid the ink staying above the mixing and stirring chamber 17 for a long time or the ink being deposited below the mixing and stirring chamber 17, thereby affecting the mixing effect.

[0060] Combination Figure 7 As shown, a guide portion 171 is provided at the bottom of the inner cavity of the mixing and stirring cavity 17 . The design of the guide portion 171 helps to guide the ink that has been mixed evenly to the discharge pipe 13 so as to be discharged from the tank body 1 .

[0061] The working mode of the utility model is as follows:

[0062] First, pour water of a corresponding proportion into the water storage chamber 16 in the tank body 1 through the water inlet pipe 11. The water in the water storage chamber 16 will flow into the mixing and stirring chamber 17 through the connecting hole 18 and mix with the ink. After the nozzle 19 is set, the water will pass through the nozzle 19 to form a fine mist, which can reduce the impact of the water flow on the ink and increase the contact area between the water and the ink, so that the two can be mixed more evenly and quickly. Then, pour the ink to be adjusted into the mixing and stirring chamber 17 of the tank body 1 through the feeding pipe 12. After pouring the ink, add the required additives from the feeding pipe 12. Secondly, start the driving member 45, so that the rotating disk 46 starts to rotate, driving the driving pin 47 to slide back and forth in the slide groove 42, so that the driving block 41 can slide back and forth on the upper part of the tank body 1. In this process, since the rack 43 is meshed with the gear 3, when the driving block 41 slides to one side, the gear 3 will rotate clockwise, and the gear 3 will drive the stirring shaft 21 to rotate, and the stirring shaft 21 will drive the first stirring rod 22, the second stirring rod 23, the scraper 24 and the spiral stirring rod 25 to rotate together, and one side of the scraper 24 is in contact with the inner wall of the mixing and stirring chamber 17, so that when the stirring assembly 2 rotates, the scraper 24 can scrape off the ink attached to the inner wall, so that it can re-participate in the mixing process and improve the mixing efficiency. The spiral stirring rod 25 is fixed between the first stirring rod 22 and the second stirring rod 23. Its spiral shape design helps to push the ink downward or push the ink deposited below upward to flow, so as to prevent the ink from staying above the mixing and stirring chamber 17 for a long time or the ink from being deposited below the mixing and stirring chamber 17, thereby affecting the mixing effect. On the contrary, when the driving block 41 slides to the other side, the gear 3 will rotate counterclockwise and drive the stirring shaft 21, the first stirring rod 22, the second stirring rod 23, the scraper 24 and the spiral stirring rod 25 to rotate counterclockwise together. Finally, after the ink stirring is completed, the discharge pipe 13 is opened, and under the action of the guide part 171, the ink is discharged from the discharge pipe 13 into the tank body 1. In addition, the device also includes a heating mechanism and a control mechanism to meet different working requirements. The function of the heating mechanism is mainly to adjust the temperature of the ink. In some cases, the ink needs to be mixed and stirred at a specific temperature to achieve the best effect. The heating mechanism can heat the inside of the tank body 1 as needed to ensure that the ink remains within a suitable temperature range. The control mechanism is used to control the operation process of the entire device. It can set and adjust the working parameters of each component, such as water inlet speed, stirring speed, heating temperature, etc., to meet different working requirements. At the same time, the control mechanism can also monitor the working status of the device, such as detecting the mixing degree and temperature of the ink, and automatically adjust it when necessary to ensure the normal operation of the equipment and obtain high-quality mixing results.

[0063] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
