Abstract
The objective of the invention is to provide a circulating ink-supply device for an ink jet printer, and the device consists of an ink pump, an ink storage tank, an incoming ink distributor, ink spraying heads, a backflow distributor, and a backflow ink pump. The ink pump enables ink to be stored in the ink storage tank from an ink bottle. When an ink level reaches a backflow port of the ink storage tank, the redundant ink flows back to the ink bottle through a backflow pipe and an opened valve, and the ink level of the ink storage tank is maintained at a specific height, wherein the height difference between the ink level and the ink spraying heads is H. The ink in the ink storage tank is pumped to the incoming ink distributor through a filter and the ink pump, and then is distributed to all ink spraying heads. The ink flows through the backflow distributor, and returns to the ink storage tank through the backflow ink pump.
Description
Technical field
The present invention relates to inkjet printing field.
Background technology
The image information of digital processing directly can be printed to (paper, glass, pottery etc.) on required medium by inkjet printing.The printhead of every platform machine is all combined by multiple ink gun.Technology current with regard to ink supply: ink needed for ink gun, then to be drawn onto in ink gun by siphon pipe from black bottle pump to ink storage tank by pump.Its shortcoming is: the difference in height of ink storage tank and ink gun requires strictly, and can produce ink gun air inlet or drip black phenomenon when variation of ambient temperature is larger time, impact normally works, and adjusts also very loaded down with trivial details.On the other hand, this ink supply mode ink one direction flows from black bottle to ink gun, and the impurity in ink, sediment can be accumulated in ink gun gradually, and the time has been grown and will block ink gun, causes ink gun to be scrapped in advance.
Summary of the invention
The present invention is intended to overcome or alleviate at least one or more technical problem existed in above-mentioned prior art.
At least one technical scheme in the present invention is achieved in that
Pump is ink from black bottle pump to ink storage tank, and when ink level reaches ink storage tank refluxing opening, unnecessary ink is through return duct, and the valve return opened is in black bottle, and the liquid level in ink storage tank remains on specific height, and the difference in height of itself and ink gun is H.In ink storage tank ink through filter by pump pump in ink feed distributor, be redistributed in each ink gun, through reflux splitter, by backflow pump blowback ink storage tank.
Other goal of the invention that the present invention can realize and other technique effect that can obtain are set forth combining in following detailed description of the invention the description of specific embodiment and the signal of accompanying drawing.
Accompanying drawing explanation
In order to above and other objects of the present invention, feature and advantage can more be become apparent, below in conjunction with the drawings and specific embodiments, the invention will be further described.

Detailed description of the invention
In order to above and other objects of the present invention, feature and advantage can more be become apparent, below in conjunction with the drawings and specific embodiments, the invention will be further described.
Fig. 1 is the schematic diagram of the cyclic ink supply device of ink gun according to the present invention's specific embodiment.
Detailed description of the invention
Be described below in detail specific embodiments of the invention, the example of specific embodiment is shown in the drawings, and wherein identical from start to finish label represents same or analogous element.Below with reference to the accompanying drawings the specific embodiment described is exemplary, is intended to explain the present invention, and can not be interpreted as one restriction of the present invention.
See Fig. 1, pump (6) ink from black bottle (8) pump to ink storage tank (7), when ink level reaches ink storage tank refluxing opening (701), unnecessary ink is through return duct, the valve (9) opened is back in black bottle (8), liquid level in ink storage tank remains on specific height, and the difference in height of itself and ink gun (101-113) is H.In ink storage tank ink through filter (10) by pump (4) pump ink feed distributor (3), be redistributed in each ink gun (101-113), through reflux splitter (2), by backflow pump (5) blowback ink storage tank.Ink is circulation at ink gun, so on the one hand the impurity produced in ink gun, sediment is taken back ink storage tank, is filtered out during recirculation by filter (10); Ink storage tank taken back by the ink that the bubble that air inlet a small amount of in ink gun on the other hand produces also can be recycled, thus the broken string difficult problem automatically solving ink gun air inlet and produce.
In this example, the difference in height of ink storage tank liquid level and ink gun (101-113) is H, the setting of this H can ensure ink-jet printer quit work state time, ink gun does not drip ink, allow a small amount of air inlet of ink gun, and during ink-jet printer duty, the flow of ink feed pump less times greater than the flow of backflow pump, to compensate the slightly large problem of H value.
Claims (2)
1. a cyclic ink supply device for ink-jet printer, be applied to ink gun ink supply, it is characterized in that: ink enters ink gun via ink feed distributor, then be back in ink storage tank by reflux splitter, the height difference H of ink gun and ink storage tank liquid level is larger.
2. based on claim 1, have ink filter and ink feed pump, have backflow pump between reflux splitter and ink storage tank between ink storage tank and ink feed distributor, the flow of ink feed pump is a bit larger tham backflow pump flow.
