In this embodiment, the ink outlet 61 is communicated with the first cavity 72 through a pipeline, and the ink outlet 61 is located on the upper surface of the first cavity 72 at the position where the ink outlet 61 is communicated with the first cavity 72, meanwhile, an ink inlet 77 is further provided on the upper end surface of the first cavity 72, the ink inlet 77 is covered by a cover, when additional ink replenishment is needed, the ink inlet 77 is opened to place ink into the first cavity 72, in this embodiment, the first cavity 72 is larger in volume, more ink can be stored, and the ink can be not replenished for a longer time. The upper end surface of the first cavity 72 is further provided with a vent 75, and the air pressure difference in the first cavity 72 can be balanced through the vent 75, so that the air pressure in the first cavity 72 is kept consistent with the external atmospheric pressure.
The bottom of the second cavity 73 is communicated with the ink inlet 51, and a pump is arranged between the second cavity 73 and the ink inlet 51, and the ink in the second cavity 73 is driven to enter the ink tank 5 by the pump, in the embodiment, the pump is always in a working state, so that the ink can be continuously replenished into the ink tank 5; in other embodiments, the second cavity 73 is communicated with the air inlet of the air compressor 41, and a control valve is arranged between the second cavity 73 and the air inlet of the air compressor 41, in use, the control valve is opened or closed as required, so that a certain negative pressure can be generated in the second cavity 73 through the air compressor 41, on one hand, the ink in the first cavity 72 can be accelerated to be filtered into the second cavity 73, and on the other hand, when the pressure in the second cavity 73 becomes smaller, the air in the ink in the second cavity 73 can be discharged.
During specific operation, the first cavity 72 and the second cavity 73 are provided with a certain amount of ink, the pump always works, then the control valve is opened and the on-off valve 74 is opened, at the moment, the air pressure in the second cavity 73 is reduced, the ink in the first cavity 72 quickly passes through the filter screen 71 and enters the second cavity 73 under the action of the external atmospheric pressure, when the ink in the first cavity 72 is reduced to a specified amount, the on-off valve 74 is closed, then the air compressor 41 continuously pumps the air in the second cavity 73, the air pressure in the second cavity 73 is further reduced, the air in the ink in the process is continuously discharged, the control valve is closed after the specified time, the on-off valve 74 is opened, at the moment, the ink in the first cavity 72 continuously flows into the second cavity 73 again, and the ink newly entering the second cavity 73 can be above the ink of the bubble due to higher viscosity, after the operation for a period of time, the operation is repeated, so that the ink can be filtered and emptied, the whole operation can be carried out in the process of printing ink and the bubble can not be carried out, and the operation of the pump can be carried out.
Referring to fig. 2 and 3, since the printing roller on the printer body 1 has a higher temperature during printing, so that the temperature of the ink is higher, when the temperature of the ink is higher, volatile matters in the ink are easy to volatilize, so that the viscosity of the ink is higher, and the subsequent printing work is not facilitated, by arranging the cooling pipe 76 around the second cavity 73 outside the second cavity 73, and introducing cold water into the cooling pipe 76, it can be appreciated that a plurality of cooling fins can be arranged in the second cavity 73 by a person skilled in the art to accelerate the cooling of the ink; the cooled ink continuously enters the ink tank 5, so that the temperature of the ink in the ink tank 5 can be reduced, the volatilization of the ink is reduced, and the printing quality is improved.
In use, the ink is filtered and exhausted by the oil collecting piece 7, and the temperature of the ink is reduced, so that the volatilization speed of volatile matters in the ink is reduced, after the product is printed, the product is sent into the cover body 2 through the inlet 21 to be heated, so that all the volatile matters in the ink on the product volatilize, and the volatile matters move into the inner cavity 23 to be compressed by the air compressor 41 due to the high density of the volatile matters, and the compressed air is filtered by the filter piece 42 to reach the standard and then can be discharged.
The embodiments of the present invention are all preferred embodiments of the present invention, and are not intended to limit the scope of the present invention in this way, therefore: all equivalent changes in structure, shape and principle of the invention should be covered in the scope of protection of the invention.
