Description

Technical Field

[0001] This utility model relates to the field of printing ink technology, and in particular to a device for real-time detection and adjustment of the viscosity of ink in ton containers. Background Technology

[0002] Printing ink is an essential material used in printing. It is a viscous substance formed by mixing resins, pigments, fillers, and other auxiliary components, primarily through stirring and dispersion. Currently, after production, ink requires storage facilities. Traditional ink storage devices use horizontal stirring, which, with prolonged stirring, leads to a higher concentration at the bottom than at the top, resulting in uneven ink concentration and potential stratification. Furthermore, existing ton-cap ink containers, if left unused for extended periods, can experience ink sedimentation and separation. This issue exists in both solvent-based and water-based inks, but is particularly severe with water-based ton-cap inks.

[0003] Chinese patent document CN222097314U discloses an ink storage chamber inside a digital printing press, including an ink storage body. The ink storage body has an ink cavity and a compressed air cavity. Multiple track grooves are formed on the inner wall of the ink storage body. This patent solves the problem of ink surface skin formation during storage caused by the ink storage chamber remaining stationary for extended periods after installation, by using a sealing baffle and a stirring wheel.

[0004] However, the patent has a drawback: the device's structure can only be used as an ink storage chamber inside a digital printing press, and cannot be used in large ton containers. Ordinary stirring structures and their blades cannot complete the ink mixing work in larger ton containers. Furthermore, due to the lack of a detection mechanism for the internal ink, if the viscosity of the internal ink does not meet the quality requirements for normal operation, it will seriously affect the printing quality.

[0005] Chinese patent document CN119386741B discloses an intelligent mixer, method, controller, and medium for screen printing on enamel glass. The system includes: multiple material tanks for holding ink materials corresponding to the screen printing on enamel glass; an intelligent conduit assembly including multiple inlet and outlet ports, with the inlet ports connected to the material tanks; a mixing tank including an inlet and an outlet; a stirring rod disposed inside the mixing tank; a viscosity sensor disposed inside the stirring rod; and a controller for acquiring screen printing information corresponding to the enamel glass, determining the ink material ratio corresponding to the enamel glass based on the screen printing information, identifying a target inlet port among the multiple inlet ports, opening the target inlet port to allow the ink material to flow into the mixing tank through the intelligent conduit assembly, determining the target ink viscosity based on the screen printing information, and controlling the stirring rod to stir based on the real-time viscosity measured by the viscosity sensor and the target ink viscosity, so that the stirred ink flows out through the outlet to complete the screen printing on the enamel glass.

[0006] However, the patent has a drawback: the mixing tank relies on a regular stirring rod to agitate the ink, which causes a skin to easily form on the surface of the inner tank wall. This not only wastes ink but also affects the quality of ink mixing. Especially in large-scale production, a large amount of ink remains on the inner tank wall, making it difficult to use and potentially causing blemishes during subsequent printing.

[0007] Therefore, how to achieve efficient and energy-saving ink mixing in ton containers, and how to quickly and automatically adjust the ink viscosity to meet the factory viscosity requirements when the ink viscosity in the ton container is not up to standard, are problems that existing technologies urgently need to solve.

[0008] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

[0026] The following is a detailed explanation with reference to the accompanying drawings.

[0027] Example 1

[0028] This invention provides a device for real-time detection and adjustment of the viscosity of ink in ton containers, such as... Figure 1 As shown, the device includes a ton container 100. The ton container 100 is provided with an ink outlet 101 and an ink inlet 102. The ink outlet 101 and ink inlet 102 are connected to an ink conveying mechanism 300 for transporting ink from the vertically downward bottom layer of the ton container 100 to the vertically upward top layer. Preferably, the ink conveying mechanism 300 is connected to the ink outlet 101 and ink inlet 102 respectively via flexible hoses. The ink conveying mechanism 300 can have a built-in suction device, allowing the ink in the ton container 100 to be drawn out from the ink outlet 101 and discharged from the ink inlet 102. The ton container 100 also has an agitator 200 inside for stirring the ink transported by the ink conveying mechanism 300. In this invention, the agitator 200 is preferably a pneumatic agitator controllable by compressed gas, but this does not mean that other stirring components, such as an electric motor, cannot be used.

[0029] This invention utilizes a circulation pipeline comprised of an ink conveying mechanism 300 to transport ink that has settled at the bottom of the ton container 100 vertically downwards to the top of the ton container 100 vertically upwards. This allows the ink to participate in the stirring process of the stirring element 200 within the ton container 100, increasing stirring efficiency and preventing ink stratification and separation within the ton container 100 during use. The ink conveying mechanism 300 can also transport some of the separated ink to the top of the ton container 100 for re-participation in the stirring process.

[0030] According to a preferred embodiment, such as Figure 5 As shown, the device also includes a base 400 for supporting the ton container 100. The ton container 100 has a liquid outlet extending from the base 400 at its vertically downward end. The base 400 supports the ton container 100. Preferably, the base 400 is configured as a recessed table-like metal structure to place the ton container 100 within the recess. Preferably, the contact surface between the base 400 and the ton container 100 is hollowed out, allowing the liquid outlet to extend.

[0031] According to a preferred embodiment, the stirring member 200 includes a plurality of stirring blades 201 and a support column 202. At least one stirring blade 201 is located on the support column 202 corresponding to the output port 302 of the ink conveying mechanism 300. At least one stirring blade 201 is located on the support column 202 corresponding to the input port 301 of the ink conveying mechanism 300. In this invention, the stirring blades 201 can be located at least on the support column 202 relative to the ink outlet 101 and the ink inlet 102, thereby forming a cyclic process of ink stirring and conveying in subsequent stirring operations.

[0032] According to a preferred embodiment, such as Figure 3 and Figure 4 As shown, several stirring blades 201 are arranged in a spiral upward manner on the support column 202, or several stirring blades 201 are arranged in a hierarchical manner on the support column 202. The spiral upward manner can refer to the fact that the heights between adjacent stirring blades 201 are different, and the height of the next stirring blade 201 is greater than the height of the previous stirring blade 201. Thus, as the stirring blades 201 rotate with the support column 202, the ink can spiral upward with the stirring blades 201 to improve stirring efficiency and further prevent ink separation.

[0033] According to a preferred embodiment, a plurality of stirring blades 201 are disposed inside the ton container 100, abutting against the inner wall of the ton container 100. A flexible component for preventing collision is disposed at one end of the stirring blade 201 near the inner wall of the ton container 100. Preferably, the flexible component can be a flexible material such as silicone or rubber. Preferably, the flexible component is disposed at one end of the stirring blade 201 in a covering manner. The flexible component can directly contact the inner wall of the ton container 100 instead of the stirring blade 201, thereby preventing the stirring blade 201 from scratching the inner wall of the ton container 100 during rotation. The reason why the stirring blades 201 are disposed in contact with the inner wall of the ton container 100 is that ink easily coagulates on the inner wall of the ton container 100, and simple stirring cannot remove it from the inner wall of the ton container 100. Therefore, this invention, through the arrangement of the stirring blades 201, can scrape off the ink adhering to the inner wall of the ton container 100, while the flexible component can also prevent the stirring blades 201 from scratching the ton container 100.

[0034] According to a preferred embodiment, such as Figures 2 to 4 As shown, the plurality of stirring blades 201 can be fan-shaped, inclined plate-shaped, rod-shaped, and / or spiral plate-shaped with a helical helix angle. Preferably, when the stirring blade 201 is fan-shaped, this shape can increase the stirring coverage area, so that the ink in the ton container 100 is fully stirred. However, since the contact area between the stirring blade 201 and the ink is large, the stirring blade 201 will be subjected to greater pressure, posing a risk of damage. Preferably, when the stirring blade 201 is inclined plate-shaped, this shape can carry some ink with the stirring blade 201 as it rotates, thereby improving the stirring efficiency. Preferably, when the stirring blade 201 is rod-shaped, this shape can have a higher stirring speed. Preferably, when the stirring blade 201 is spiral plate-shaped with a helical helix angle, this shape of stirring blade 201 can carry some ink spirally upward during rotation, thereby improving the stirring efficiency. This utility model can effectively improve the stirring efficiency of the stirring component 200 in the ton container 100 by setting the shape of the stirring blade 201.

[0035] According to a preferred embodiment, such as Figure 2As shown, the stirring blade 201 is provided with a plurality of through holes 203 for ink to pass through, and the plurality of through holes 203 are arranged at intervals. The diameter of the through holes 203 in its axial direction remains constant, or the diameter of the through holes 203 in its axial direction increases with the increase of height. Preferably, the through holes 203 are provided in a manner that penetrates through the stirring blade 201. In this utility model, since the stirring blade 201 abuts against the inner wall of the ton 100, the flow of ink may be obstructed. Therefore, by providing the through holes 203, the flow of ink during the stirring process can be accelerated. More preferably, the diameter of the through holes 203 gradually increases in the moving direction of the stirring blade 201. The change in diameter allows the ink flowing through the through holes 203 to flow faster. As the stirring blade 201 rotates, the ink enters from the end of the through hole 203 with a larger diameter and flows out from the end of the through hole 203 with a smaller diameter. According to fluid mechanics, the flow velocity of the ink will increase, thereby increasing the overall stirring efficiency. It should be noted that... Figure 3 and Figure 4 The through hole 203 is not shown, but this does not mean that the structure does not have a through hole 203.

[0036] According to a preferred embodiment, the inlet 301 of the ink delivery mechanism 300 is connected to the ink outlet 101, and the outlet 302 of the ink delivery mechanism 300 is connected to the ink inlet 102 to form an ink movement loop. Preferably, the connection between the inlet 301 and the ink outlet 101 and the connection between the outlet 302 and the ink inlet 102 are both via flexible hoses. These hoses can be corrosion-resistant hoses.

[0037] According to a preferred embodiment, the agitator 200 further includes a motor for driving the support column 202 to rotate. The ink delivery mechanism 300 includes an air source for providing compressed air to drive the motor. The air source and the motor are connected via a valve assembly (not shown in the figures). The motor can be a pneumatic motor to convert the pressure of the compressed air output from the air source into rotational mechanical energy. The valve assembly can be a solenoid valve controlled by a control signal. Thus, when the valve assembly is open, the air source provides compressed air to the agitator 200, causing the agitator 200 to rotate and agitate. When the valve assembly is closed, the air source does not provide compressed air, and the agitator 200 stops operating.

[0038] According to a preferred embodiment, the ink conveying mechanism 300 further includes a detection unit for detecting the viscosity of the conveyed ink. The detection unit and the valve assembly form an electrical signal circuit so that if the viscosity value detected by the detection unit is not within a preset range, the detection unit controls the valve assembly to open, thereby starting the agitator 200. In this application, the detection unit can be a digital display viscometer. The detection unit can be integrated inside the ink conveying mechanism 300. This invention obtains ink from the ton container 100 through the ink conveying mechanism 300 and detects the viscosity of the ink in the ton container in real time through the integrated detection unit, thereby determining whether to start or stop the agitator 200, preventing ink stratification and separation during use. The agitator 200 of this invention is controlled by the valve assembly. The detection unit has preset viscosity values ​​and upper and lower limit fluctuation ranges. When the detection unit detects that the viscosity of the ink in the ton container 100 is not within the preset range, the detection unit sends a control signal to open the valve assembly, thereby allowing compressed air supplied by the air source to enter the agitator 200 from the valve assembly, causing the agitator 200 to start working. When the detection unit detects that the viscosity of the ink in the ton 100 has reached the preset range, the detection unit sends a control signal to close the valve assembly, thereby preventing the compression control provided by the air source from entering the agitator 200 from the valve assembly, causing the agitator 200 to stop working.
