Description

Technical Field

[0001] The utility model belongs to the technical field of ink tanks, and particularly relates to a four-chamber solenoid valve-controlled secondary ink tank assembly. Background Art

[0002] In inkjet printing technology, the stability of the ink supply system directly affects the printing quality.

[0003] When the existing ink tank is in use, its usable capacity has certain limitations, and only one color of ink can be stored in the ink tank, and the ink storage amount in the ink tank cannot be visually observed, which affects the use efficiency. Summary of the Utility Model

[0004] The utility model aims at the problems existing in the prior art and proposes the following technical solutions:

[0005] A four-chamber solenoid valve-controlled secondary ink tank assembly includes an ink tank body. A second cover plate is installed at the top of the ink tank body, and the second cover plate and the ink tank body are locked and installed by bolts. The ink tank body is provided with four chambers. A first cover plate covers the top of a certain chamber, and a liquid level sensor penetrates through the first cover plate. The first cover plate is installed and locked on the ink tank body through a flare fitting.

[0006] By adopting the four-chamber ink tank design, four colors of ink can be integrated in one ink tank. The liquid level sensor controls the ink volume in the chamber. The full volume of a single chamber is about 700 milliliters, and the total volume of the four chambers is about 2,800 milliliters. It should be noted that the single-chamber bridge connection design in the ink tank body ensures the strength of the tank body while increasing the tank volume.

[0007] As a preference of the above technical solution, a plurality of ink discharge ports are installed at the bottom end of the ink tank body, and the input ends of the ink discharge ports are connected to the output ends of the solenoid valves.

[0008] The fluid volume in the ink tank body is automatically controlled by the liquid level sensor in cooperation with the solenoid valve, which is more convenient, faster and more accurate than the manual switch. The design of multiple ink discharge ports enables the number of ink discharge ports to be adjusted according to actual use requirements. When the printing machine or printer system suddenly loses power, the solenoid valve can automatically cut off the ink in the ink path to avoid the situation of continuous ink flow.

[0009] As a preference of the above technical solution, steel balls are installed on the side walls of the ink tank body.

[0010] Under the action of the steel balls, the process holes on the ink tank body are blocked to avoid ink leakage.

[0011] Preferably, as the above technical solution, sealing rings are connected to the tops of the ink tank bodies, and the ink tank bodies are in contact with the sealing rings when connected to the first cover plate and the second cover plate.

[0012] Under the sealing and protection of the sealing ring, it is further ensured that ink leakage is avoided when the ink tank body is installed with the first cover plate and the second cover plate.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In this application, a four-chamber ink tank design is adopted, and four-color inks can be integrated into one ink tank; the full-capacity single-chamber volume is about 700 milliliters, and the total volume of the four chambers is about 2,800 milliliters;

[0015] The fluid capacity in the ink tank body is automatically controlled by a liquid level sensor in cooperation with an electromagnetic valve, which is more convenient, faster and more accurate than a manual switch. The multi-group ink discharge port design is adopted, and the number of ink discharge ports can be adjusted according to actual usage requirements; when the printing press or printer system suddenly loses power, the electromagnetic valve can automatically cut off the ink in the ink path to avoid the continuous flow of ink.

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] In view of the problems in the prior art that the capacity has certain limitations, only one color of ink can be stored in the ink tank, and the ink storage amount in the ink tank cannot be intuitively observed, affecting the use efficiency, a four-chamber ink tank design is adopted. Four colors of ink can be integrated into one ink tank. The full-capacity single-chamber volume is about 700 milliliters, and the total volume of the four chambers is about 2,800 milliliters. A transparent visible window design is adopted, which can conveniently and intuitively observe the fluid color and stock status in the tank body.

[0024] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, in the embodiment of the present utility model, the four-chamber solenoid valve-controlled secondary ink tank assembly includes an ink tank body 1. A second cover plate 8 is installed at the top of the ink tank body 1, and the second cover plate 8 and the ink tank body 1 are locked and installed by bolts 5. The ink tank body 1 is provided with four chambers. The top of a certain chamber is covered with a first cover plate 3, and a liquid level sensor 4 penetrates through the first cover plate 3. The first cover plate 3 is installed on the ink tank body 1 through a compression fitting 7 and locked; by adopting the four-chamber ink tank design, four colors of ink can be integrated into one ink tank. The full-capacity single-chamber volume is about 700 milliliters, and the total volume of the four chambers is about 2,800 milliliters. It should be noted that the single-chamber bridge connection design in the ink tank body 1 ensures the strength of the tank body while increasing the tank volume. A plurality of ink discharge ports 10 are installed at the bottom end of the ink tank body 1, and the input end of the ink discharge port 10 is connected to the output end of the solenoid valve 6; since the ink tanks in the existing market do not have valves to close the ink, they use an uninterruptible power supply (UPS) to ensure that the ink tank always has negative pressure, so as to ensure that the ink does not leak. However, due to the high price of the UPS and the inability to ensure continuous power supply, liquid leakage is likely to occur; now the fluid volume in the ink tank body 1 is automatically controlled by the liquid level sensor 4 in cooperation with the solenoid valve 6, which is more convenient, faster and more accurate than a manual switch. The design of the plurality of ink discharge ports 10, and the number of ink discharge ports 10 can be adjusted according to actual use requirements; when the printing machine or printer system suddenly loses power, the solenoid valve 6 can automatically cut off the ink in the ink path to avoid the situation of continuous ink flow.

[0025] As Figure 3 shown, steel balls 2 are installed on the side walls of the ink tank body 1; under the action of the steel balls 2, the process holes on the ink tank body 1 are blocked to avoid ink leakage; sealing rings 9 are connected to the top of the ink tank body 1, and the ink tank body 1 abuts against the sealing rings 9 when connected to the first cover plate 3 and the second cover plate 8; under the sealing and protection of the sealing rings 9, it is further ensured that ink leakage is avoided when the ink tank body 1 is installed with the first cover plate 3 and the second cover plate 8.

[0026] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it.
