Problems solved by technology

When cleaning the nozzle, it is usually necessary to disassemble the nozzle and clean it separately, which is time-consuming and laborious, and the cleaning effect is poor
[0003] In addition, during the ink supply process of the nozzle, it is necessary to continuously supply ink to the nozzle and ensure that the ink inside the nozzle is maintained in balance. At present, some inkjet printing equipment uses ink gravity and provides negative pressure to maintain the balance of ink in the nozzle. However, if provided Inaccurate negative pressure control of the nozzle will cause excessive negative pressure, which may suck the dust and particles outside the nozzle into the nozzle and cause the nozzle to clog; in addition, if the ink is stored in the nozzle for a long time, it is easy to solidify, and the ink solidifies It will also cause the nozzle to clog, which will cause trouble to the cleaning of the nozzle and make it difficult to clean the nozzle

Embodiment 1

[0024] This embodiment provides an ink supply and cleaning device for a nozzle, including an ink supply unit for supplying ink to the nozzle, a liquid supply unit for providing cleaning liquid to the nozzle, and a gating unit, one end of the gating unit is connected to the The nozzle is in communication, and the other end of the nozzle can selectively communicate with the ink supply unit or the liquid supply unit.

Embodiment 2

[0026] Such as figure 1 As shown, in this embodiment, the nozzle ink supply and cleaning device includes an ink supply unit for providing ink to the nozzle 38, a liquid supply unit for providing cleaning liquid to the nozzle 38, and a gating unit, the gating One end of the unit communicates with the spray head 38, and the other end can selectively communicate with the ink supply unit or the liquid supply unit.

[0027] In this embodiment, the ink supply unit includes an ink supply chamber, an ink storage chamber 4 and a first drive mechanism, wherein the ink supply chamber is connected to the gating unit; the ink storage chamber 4 is connected to the ink supply chamber communicated for storing ink; the first driving mechanism is used for delivering the ink in the ink storage chamber 4 to the ink supply chamber. The liquid supply unit includes a liquid supply chamber, a liquid storage chamber 3 and a second drive mechanism, the liquid supply chamber is connected to the gating ...

Embodiment 3

[0046] The difference between the nozzle ink supply and cleaning device in this embodiment and Embodiment 2 is that in this embodiment, the ink supply unit does not have a first alarm mechanism, and the liquid supply unit does not have a second alarm mechanism.

[0047] In this embodiment, the ink storage chamber 4 and the liquid storage chamber 3 are respectively provided with observation windows, and the operator can check the liquid level height of the ink in the ink storage chamber 4 and the liquid level of the cleaning liquid in the liquid storage chamber 3 through the observation windows. high.

[0048] Other structures of the nozzle ink supply and cleaning device in this embodiment are the same as those in Embodiment 2, and will not be repeated here.

Abstract

The invention provides a jet nozzle ink supply and cleaning all-in-one device. The jet nozzle ink supply and cleaning all-in-one device comprises an ink supply unit used for providing ink for a jet nozzle, a fluid supply unit used for providing cleaning fluid for the jet nozzle, and a selective communication unit, wherein one end of the selective communication unit is communicated with the jet nozzle, and the other end of the selective communication unit is selectively communicated with the ink supply unit or the fluid supply unit. The jet nozzle ink supply and cleaning all-in-one device is simple in structure, is convenient to use and can clean the jet nozzle without detaching the jet nozzle.

Description

technical field [0001] The invention belongs to the technical field of inkjet printing, and in particular relates to an integrated device for ink supply and cleaning of a nozzle. Background technique [0002] In the field of inkjet printing, for inkjet printing equipment, it is very difficult to clean the nozzle. When cleaning the nozzle, it is usually necessary to disassemble the nozzle and clean it separately, which is time-consuming and laborious, and the cleaning effect is poor. [0003] In addition, during the ink supply process of the nozzle, it is necessary to continuously supply ink to the nozzle and ensure that the ink inside the nozzle is maintained in balance. At present, some inkjet printing equipment uses the gravity of the ink and provides negative pressure to maintain the balance of the ink in the nozzle. However, if provided Inaccurate negative pressure control of the nozzle will cause excessive negative pressure, which may suck the dust and particles outsid...
