The main ink tank assembly includes: a main ink tank 31, a stirring device 311, a liquid level sensor 312, an ink supply pump 313, a first filter 33, and a large circulation pump 314. The ink is filled in the main ink tank 31, and the stirring device 311 can stir the ink in the main ink tank 31 after being opened, so that the ink in the main ink tank 31 is prevented from being deposited. The liquid level sensor 312 is disposed in the main ink tank 31 and is used for sensing the liquid level of the main ink tank 31.
The secondary cartridge assembly includes: the ink jet head comprises a two-stage ink box cover 11, a two-stage ink box 12, a low negative pressure cavity 121, a high negative pressure cavity 122, a first sensor 13, a small circulating pump 32, a second filter 35 and a spray head 34. The top of second grade ink horn 12 is located to second grade ink horn 11 lid, the centre of second grade ink horn 12 is equipped with a vertical baffle, and the baffle is divided into low negative pressure chamber 121 and high negative pressure chamber 122 about with the inner space of second grade ink horn 12, low negative pressure chamber 121 and high negative pressure chamber 122 separate each other sealed. The low negative pressure chamber 121 is communicated with the ink inlet of the nozzle 34 via a second filter 35, and the high negative pressure chamber 122 is communicated with the ink outlet of the nozzle 34. The low negative pressure cavity 121 and the high negative pressure cavity 122 are communicated with each other through a small circulating pump 32 and used for pumping ink in the high negative pressure cavity 122 to the low negative pressure cavity 121, and sensors 13 are arranged in the high negative pressure cavity 122 and the low negative pressure cavity 121 to sense liquid levels. The high negative pressure draws ink from the printhead 34 into the high negative pressure chamber 122, and the low negative pressure balances the difference in fluid pressure from the ink in the low negative pressure chamber 121 to the printhead 34. When the nozzle of the nozzle 34 needs to be squeezed and cleaned, the air pressure in the low negative pressure cavity 121 and the air pressure in the high negative pressure cavity 122 are both switched to be positive pressure air, because of negative pressure difference, ink is sucked into the high negative pressure cavity 122 from the low negative pressure cavity 121 along the nozzle 34, when the high negative pressure cavity 122 reaches the detection point of the sensor I13, the small circulating pump 32 starts to pump ink from the high negative pressure cavity 122 to the low negative pressure cavity 121, and small circulation from the second-stage ink box 12 to the nozzle 34 is completed.
The ink supply pump 313 communicates the main ink tank 31 with the low negative pressure chamber 121, and is configured to pump the ink in the main ink tank 31 into the low negative pressure chamber 121. The large circulation pump 314 communicates the high negative pressure chamber 122 with the main ink tank 31, and is used for pumping the ink in the high negative pressure chamber 122 back to the main ink tank 31. When receiving an ink pumping command from the secondary ink cartridge assembly, the ink supply pump 313 pumps the ink in the main ink tank 31 into the low negative pressure chamber 121 of the secondary ink cartridge 12 through the first filter 33. The large circulation pump 314 intermittently pumps the ink in the high negative pressure cavity 122 of the secondary ink box back to the main ink barrel 31, and the large circulation of the ink from the secondary ink box assembly to the main ink barrel assembly is completed.
The positive and negative pressure control system is divided into two paths, wherein one path controls the high negative pressure cavity 122, and the other path controls the low negative pressure cavity 121. Each positive and negative pressure control system comprises: the positive and negative pressure control assembly 21 switches positive and negative pressure, the printing work is always in a negative pressure state, and only cleaning ink pressing is switched to positive pressure. The negative pressure box assembly 22 can distribute a plurality of interfaces to connect with the second-stage ink cartridges 12 of different color inks, and control the second-stage ink cartridges 12 of different color inks to suck the ink back to the air pipe due to the excessive negative pressure. The second sensor 221 is arranged in the negative pressure box assembly 22, and the second sensor 221 gives an alarm when sensing that ink exists in the negative pressure box assembly 22.
The working principle of the utility model is as follows:
all components are installed well, and the secondary ink box component and the negative pressure box component 22 are required to be tested for tightness so as to avoid air leakage from influencing the performance. And setting a software program to communicate the air passages and the ink tubes, and finally installing the spray heads 34 after all the air passages and the ink tubes are installed.
The main ink barrel 31 is poured with ink, the software is started, the ink supply pump 313 receives an ink shortage command from the sensor I13 to start supplying ink, and the ink is injected into the low negative pressure cavity 121 through the filter I33. When the liquid level rises to the detection point of the first sensor 13, the ink supply pump 313 stops working. The stirring component 311 can adjust the speed according to the actual situation. When the ink is used, the liquid level is lower than the detection point of the liquid level sensor 312, an alarm is given to remind of ink adding, so that the condition that the printing quality is influenced by the fact that the ink is lack of ink and enters air is avoided.
Ink with negative pressure difference can be sucked into the high negative pressure cavity 122 from the low negative pressure cavity 121, when the liquid level of the high negative pressure cavity 122 rises to the monitoring point of the first sensor 13, the small circulating pump 32 receives a command to start working, and the ink is pumped into the low negative pressure cavity 121 from the high negative pressure cavity 122 to complete a small circulation, so that the ink in the secondary ink box 12 flows to avoid precipitation. The magnitude of the negative pressure difference determines the circulating flow rate, and the value of the ink adjustment is required to be continuously integrated with the printing quality.
The software program controls intermittent operation of the large circulating pump 314, and the frequency is adjustable. The ink is pumped from the high negative pressure cavity 122 to the main ink barrel 31, and the large circulation of the ink from the secondary ink box component to the main ink barrel component is completed. For the machine which does not print for a long time, the secondary ink box and the pipeline ink generate an exchange cycle, so that the ink is not easy to precipitate.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
