Its core technologies have been widely applied in high-end printing equipment, driving the industry's transformation towards green and intelligent manufacturing. In the future, with the deepening of IoT and AI technologies, this system will become a core component of Industry 4.0 in printing.
[0003] In order to reduce the impact of low temperature on ink supply in low-temperature environments, existing intelligent ink supply control systems for printing presses generally have heating structures to heat the pipes or ink storage tanks. However, the pipe heating and insulation structures can be damaged during long-term use. When replacing them, the ink supply to the pipes needs to be stopped, resulting in low production efficiency. Utility Model Content

[0005] Therefore, one objective of this utility model is to propose an intelligent ink supply control system for printing presses to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

One side of the storage tank is connected to an air bubble eliminator via a pipe. One side of the air bubble eliminator is connected to a first electromagnetic three-way valve via a pipe. Branch pipes are fixedly installed on both sides of the first electromagnetic three-way valve. A second electromagnetic three-way valve is fixedly installed at the end of each branch pipe away from the first electromagnetic three-way valve. One side of the second electromagnetic three-way valve is connected to a temperature measuring box via a pipe. One side of the temperature measuring box is connected to a secondary ink cartridge via a pipe. A printing inkjet is provided on one side of the secondary ink cartridge. The head, both of the two branch pipes are provided with a first heating structure. The first electromagnetic three-way valve, the second electromagnetic three-way valve, the temperature measuring box and the first heating structure are all connected to the control center. The technical effect achieved by the above scheme is: the temperature measuring box monitors the change of ink temperature in real time. If the temperature change is too large, it is determined that there is a problem with the first heating structure on the surface of one branch pipe. Then, the control center controls the first electromagnetic three-way valve and the second electromagnetic three-way valve to change the ink flow into the branch pipe on the other side, and notifies the staff to repair the first heating structure on the surface of the branch pipe on the other side, so as to ensure the operation of the printing operation and improve production efficiency.

The temperature sensor and liquid level sensor inside the temperature measuring chamber are connected to the control center. The technical effect achieved by the above solution is that the temperature of the ink inside the temperature measuring chamber can be monitored in real time through the temperature sensor, thereby ensuring that the first heating structure on the surface of the branch pipe can operate normally. If the temperature change is too large, it is determined that there is a problem with the first heating structure on the surface of one branch pipe. Then, the control center issues an alarm and changes the flow direction of the ink to make it enter the interior of another branch pipe. At the same time, the liquid level sensor can sense the liquid level inside the temperature measuring chamber.
[0010] Preferably, as described in any of the above solutions, the liquid storage tank is equipped with a stirring structure, a temperature sensor, and a liquid level sensor. The technical effects achieved by adopting the above solutions are: the temperature sensor and liquid level sensor inside the liquid storage tank can replenish the ink in a timely manner when the ink inside the liquid storage tank is insufficient; at the same time, the temperature of the ink inside the liquid storage tank can be controlled by the cooperation between the temperature sensor and the second heating structure; and the stirring structure can prevent ink skinning when the ink is inside the liquid storage tank, thus ensuring the quality of the ink.

A bubble eliminator 2 is connected to one side of the storage tank 1 via a pipe. A first electromagnetic three-way valve 3 is connected to one side of the bubble eliminator 2 via a pipe. Branch pipes 4 are fixedly installed on both sides of the first electromagnetic three-way valve 3. A second electromagnetic three-way valve 5 is fixedly installed at the end of each branch pipe 4 away from the first electromagnetic three-way valve 3. A temperature measuring box 6 is connected to one side of the second electromagnetic three-way valve 5 via a pipe. A secondary ink cartridge 7 is connected to one side of the temperature measuring box 6 via a pipe. A printing nozzle 8 is installed on one side of the secondary ink cartridge 7.

The first electromagnetic three-way valve 3, the second electromagnetic three-way valve 5, the temperature measuring box 6, and the first heating structure 9 are all connected to the control center. The temperature measuring box 6 monitors the ink temperature in real time. If the temperature change is too large, it is determined that there is a problem with the first heating structure 9 on the surface of one side of the pipe 4. Then, the control center controls the first electromagnetic three-way valve 3 and the second electromagnetic three-way valve 5 to change the ink flow into the other side of the pipe 4, and notifies the staff to repair the first heating structure 9 on the surface of the other side of the pipe 4 to ensure the operation of the printing operation and improve production efficiency.
[0020] As an optional technical solution of this utility model, the first heating structure 9 is a self-limiting electric heating tape, and the surface of the liquid storage tank 1 is provided with a second heating structure 10, which is a circulating water heating structure.

The temperature sensor can monitor the temperature of the ink inside the temperature measuring box 6 in real time, thereby ensuring that the first heating structure 9 on the surface of the branch pipe 4 can operate normally. If the temperature changes too much, it is determined that there is a problem with the first heating structure 9 on the surface of one branch pipe 4. Then, the control center issues an alarm and changes the flow direction of the ink to make it enter the interior of another branch pipe 4.

[0026] An intelligent ink supply control system for a printing press operates as follows: The temperature measurement box 6 monitors the ink temperature in real time. If the temperature change is too large, it indicates that the first heating structure 9 on the surface of one side of the pipe 4 is malfunctioning. Then, the control center controls the first electromagnetic three-way valve 3 and the second electromagnetic three-way valve 5 to change the ink flow to the other side of the pipe 4 and notifies the staff to repair the first heating structure 9 on the surface of the other side of the pipe 4, thus ensuring the smooth operation of the printing process and improving production efficiency.
[0027] In summary, this intelligent ink supply control system for the printing press, through the coordination between the liquid storage tank 1, the first electromagnetic three-way valve 3, the branch pipe 4, the second electromagnetic three-way valve 5, the temperature measuring box 6, the auxiliary ink cartridge 7, the printing nozzle 8, the first heating structure 9, and the control center, can reduce the impact of low temperature when ink moves inside the pipeline.
