Description

Technical Field

[0001] The utility model belongs to the technical field of ink mixing and relates to an ink mixing tank. Background Art

[0002] Ink is one of the indispensable core materials in the printing industry. The ink is sprayed or applied to the corresponding carrier in a specific form through printing equipment, such as gravure printing machines, inkjet printers, etc. Since the ink raw materials usually have a large viscosity or concentration, they usually need to be mixed with diluents and diluted before use.

[0003] At present, the market usually needs to calculate the corresponding ratio of diluent and ink, inject them into the mixing tank one by one or at the same time, and then stir and mix them to obtain the ink of the required concentration or viscosity. However, in practice, it is found that since the ratio of diluent and ink is theoretically calculated, and there are usually certain differences between the ink and diluent themselves, such as different batches, different temperatures, and products provided by different manufacturers (even if they all meet the national standards, there are still certain differences), so the ink concentration will still be too high or too low, and it needs to be fine-tuned manually, and the use effect is poor.

If it is qualified, the mixed ink can be used directly. However, if the concentration is too high, more diluent is pumped in, and vice versa. However, no matter whether the ink or the diluent is added, it is necessary to further use the detection cavity and the ink dripping port for detection until the concentration reaches a suitable level before use. How to calculate the concentration of the dripping time and the amount of ink requires each manufacturer to design it according to its own needs and circumstances, and it is not a fixed value; secondly, the diameter of the ink dripping port is very small, so it can make the ink drip slowly and make the calculation result more accurate. At the same time, since the diameter of the ink dripping port is very small, even if the ink dripping port and the tank body are continuously connected, the impact on the overall ink dripping completion time is very small, and the impact on the viscosity calculation result can be ignored; at the same time, the air inlet pipe can allow the gas in the tank body to enter the containing cavity during the ink dripping process, so that the ink can drip normally and smoothly, and secondly, it can better prevent external air from entering the tank body, ensuring the cleanliness of the ink.

[0049] A positioning bolt 28 is movably provided through the sealing cover 9 , and the positioning bolt 28 is threadedly connected to the third connecting portion 18 c.

[0050] The utility model provides an ink mixing tank. When mixing ink and diluent, firstly, an external vacuum pump is started, and a valve (preferably an electrically controlled valve) on a vacuum tube 3 is opened to form a negative pressure in a tank body 1. Then, valves (preferably an electrically controlled valve) on a first adding tube 4 and a second adding tube 5 are opened respectively to allow ink and diluent to enter the tank body 1 according to a calculated ratio. After the ink and diluent are mixed, a detection pump is started to send the ink in the tank body 1 (i.e., the ink mixed with the diluent) into a receiving chamber 7 of a detection chamber 6 through an ink tube 10. When the ink is input to a specified amount, the timing starts until the ink is completely dripped from an ink droplet 8, and the total time is calculated. Then, the concentration or viscosity of the ink at this time can be calculated by the ink amount in the receiving chamber 7 and the dripping time. If it is qualified, the mixed ink can be used directly. However, if the concentration is too high, more diluent is pumped in, and vice versa. However, after the ink or the diluent is added, it is necessary to further use the detection chamber 6 and the ink droplet 8 for detection until the concentration reaches a suitable level before use. How to calculate the concentration of the dripping time and the amount of ink requires each manufacturer to design it according to its own needs and circumstances, and it is not a fixed value; secondly, the diameter of the ink dripping port 8 is very small, so it can make the ink drip slowly and make the calculation result more accurate. At the same time, since the diameter of the ink dripping port 8 is very small, even if the ink dripping port 8 and the tank body 1 are continuously connected, the impact on the overall ink dripping completion time is very small, and the impact on the viscosity calculation result can also be ignored; at the same time, the air inlet pipe 11 can allow the gas in the tank body 1 to enter the accommodating chamber 7 during the ink dripping process, so that the ink can drip normally and smoothly, and secondly, it can better prevent external air from entering the tank body 1, ensuring the cleanliness of the ink.

[0051] The first adding tube 4, the second adding tube 5, the detection cavity 6, etc. are all connected to the can cover 2, so that in actual production and assembly, the corresponding structures can be connected to the can cover 2 and then assembled with the can body 1, which is simple and convenient. At the same time, the cylindrical sealing tube 17 at the bottom of the rod body is closely attached to the inner wall of the can body 1, further ensuring the sealing and cleanliness of the ink.

[0052] When the ink and diluent are added into the tank body 1, the mixing motor 12 drives the stirring rod 13 to rotate, and then drives the stirring blade 14 to stir the ink and the diluent, which can accelerate the mixing of the ink and the diluent, and also make the ink pumped into the detection cavity 6 more uniform, thereby ensuring the detection result.

[0053] When the ink in the accommodating chamber 7 reaches a certain height, it will act on the top liquid level sensor 15, which sends a signal to the controller, and then the controller controls the detection pump to stop working, thus ensuring that the amount of ink delivered each time is fixed, and at this time the top of the ink is lower than the top of the air inlet pipe 11. When the ink drips out, the bottom liquid level sensor 16 sends a signal to the controller, and the controller can obtain the time when the ink drips out and calculate the concentration of the ink at this time.

[0054] When assembling the sealing cover 9 and the detection chamber 6, the sealing cover 9 is first rotated to a direction away from the detection chamber 6, and the anti-slip portion 27 is located above the clearance opening 24; then the sealing cover 9 is lowered and the anti-slip portion 27 is inserted into the clearance opening 24, and the linkage rod 26 is inserted into the rotation hole 23, until the sealing cover 9 is fitted into the detection chamber 6, and then the sealing cover 9 is rotated horizontally, and the side of the sealing cover 9 is pressed against the inner wall of the fastening member 22, and the anti-slip portion 27 is also rotated to a state of being misaligned with the clearance opening 24; finally, the sealing cover 9 is fixed by the positioning bolt 28. The cover 9 is fixedly connected to the third connecting portion 18c. At this time, the sealing cover 9 is fixedly connected to the detection cavity 6 in the horizontal direction and in the vertical direction. At the same time, there is a flexible sealing layer between the sealing cover 9 and the detection cavity 6, which can ensure the sealing and stability of the connection between the sealing cover 9 and the detection cavity 6 and prevent external impurities from entering; secondly, only one positioning bolt 28 is needed in the entire connection process, and the operation is convenient. In the vertical direction, the anti-slip portion 27, the buckle 22 and the positioning bolt 28 can limit the sealing cover 9, thereby ensuring the sealing.

[0055] The inner wall of the detection cavity 6 is also provided with an ink shield 29 , which is in the shape of a shield with its opening facing downward. The top opening of the air inlet pipe 11 is located in the opening of the ink shield 29 , and the ink shield 29 can prevent ink from entering the air inlet pipe 11 .

[0056] Example 2

[0057] The difference from the first embodiment is that, Fig. 9 As shown, three connecting bolts 19 are movably provided through the sealing cover 9 , and the three connecting bolts 19 are threadedly connected to the three connecting blocks 18 respectively.

[0058] An annular sealing portion 20 is disposed at the bottom of the sealing cover 9 , and a sealing groove 21 matched with the sealing portion 20 is formed at the top of the detection cavity 6 .

[0059] When connecting the sealing cover 9, the sealing cover 9 is put on the top of the detection cavity 6 from top to bottom, and finally three connecting bolts 19 are passed through the sealing cover 9 and threadedly connected to the connecting block 18; secondly, the sealing part 20 is now engaged in the sealing groove 21, which can further ensure the sealing effect.

[0060] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
