[0020] The following further describes and explains the specific embodiments of the present invention with reference to the accompanying drawings.

[0021] Such as Figures 1 to 3As shown in the figure, a positive and negative pressure ink supply printing device applied to a cartridge type wire printer includes an ink supply placement table 1, a head safety bottle 2, a printing cartridge 3, a negative pressure safety bottle 4, and an external control board 5. An elevating placement rack 6 is installed on the ink supply placement table 1, and the head safety bottle 2 is installed on the elevating placement rack 6. The output end of the head safety bottle 2 is connected to the printing cartridge 3. There are two head safety bottles 2, which are symmetrically arranged on the elevating placement rack 6 respectively. There are four printing cartridges 3, which are divided into two groups of two each. The head safety bottle 2 is connected to each group of printing cartridges 3 for ink supply. An elevating motor 7 is installed on the elevating placement rack 6, and the elevating motor 7 drives the elevating placement rack 6 to move up and down. The head safety bottle 2 stores printing ink. By setting the elevating placement rack 6 and the elevating motor 7, the smooth lifting can be realized, the vibration damage of the ink cartridge and the head safety bottle 2 can be reduced, and the service life of the equipment can be improved.

[0022] As Figures 1 to 3 shown in the figure, the head safety bottle 2 is connected to the negative pressure safety bottle 4 through a connecting air pipe 8, and the negative pressure safety bottle 4 is connected to the external control board 5 through a connecting air pipe 8. The negative pressure safety bottle 4 is connected between the head safety bottle 2 and the external control board 5. The negative pressure is used to automatically remove the air in the ink cartridge, reducing ink waste. When in use, the head safety bottle 2 is connected to the ink supply pot, and the ink supply pot can automatically stir and add ink, eliminating the need for frequent ink addition operations. The ink path has a dual-channel ink supply, making it more convenient to replace ink and improving work efficiency.

[0023] By adding the negative pressure safety bottle 4 and the external control board 5, not only can the ink supply control of the ink cartridge ink volume be realized, but also the ink in the ink cartridge can be back-sucked when starting up, the air can be removed, and the ink delivery can be controlled without manual ink addition. At the same time, the positive pressure is used to press the ink to keep the ink cartridge nozzle unobstructed, and there will be no ink breakage problem, improving the quality of printing and inkjetting.

[0024] The external control board 5 can directly perform relevant operations on the system on the printing device panel, and is compatible with the functions of the system's own operation panel, including the setting and viewing of parameters, such as the setting and display of the negative pressure value. The power supply of the external control board 5 is provided by the wire printer system itself. It uses RS485 communication to directly connect to the wire printer system, with convenient wiring and a relatively long communication distance, and has no special requirements for connection.

[0025] The above is only the specific implementation manner of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantive improvement made to the present invention using this concept should belong to the act of infringing the protection scope of the present invention.
