Description
Technical Field
The utility model relates to a UV printer technical field, in particular to be used for carrying out the carminative mechanism of china ink to UV printer shower nozzle.
Background
The UV Printer (Ultraviolet LED Inkjet Printer) is a high-tech plate-free full-color digital Printer, is not limited by materials, and can be used for carrying out color photo-grade printing on the surfaces of T-shirts, sliding doors, cabinet doors, sliding doors, glass, plates, various labels, crystals, PVC, acrylic, metal, plastic, stone, leather and the like. The method does not need plate making and can be completed by one-time printing, has beautiful and rich colors, wear resistance, ultraviolet resistance, simple and convenient operation and high image printing speed, and completely accords with the industrial printing standard. During the use of the UV printer, ink is added at the beginning and ink pressing and air exhaust are carried out on the spray heads, and the spray heads are exhausted one by one. In addition, in the printing process, if a certain spray head is blocked, ink pressing needs to be carried out on a certain single spray head. When the ink is pressed, the ink flows out from the surface of the spray head, dust or bubbles are taken away by the flowing ink, and the spray head is wiped by the dust-free cloth soaked with the cleaning liquid in time.
Under the condition that the printing material amplitude is wide, a plurality of spray heads are needed to be spliced for printing. In the process of practical application, when one spray head is pressed, a small amount of ink is separated from the surfaces of other spray heads. After stopping pressing ink, the ink precipitated on the surface of other spray heads can be sucked back to the interior of the spray heads (the time is short). The back suction process will bring air into the nozzle, which has no problem in the quality of printed product due to air. The main problem of the above-mentioned situation is that the micro-motion of the rotation of the valve core disturbs the ink due to the valve core action of the ink valve, and the ink is separated from the surface of the nozzle. When ink pressing is stopped, the ink valve is normally opened again, and the valve core rotates to enable ink to flow back to bring air back, so that the quality problem of the printed product is caused.
The method adopted for solving the problem at present is that one spray head has a problem, four spray heads press ink simultaneously, and the four spray heads are wiped by dust-free cloth soaked with cleaning solution in time. One person does not wipe four nozzles in time each time, and sometimes two persons are required to operate the nozzles simultaneously. If one of the nozzles is not in operation, the above-mentioned actions are repeated again. This wastes ink and is laborious to operate.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a mechanism capable of preventing different heads from interfering with each other and preventing the heads from separating ink when ink is pressed.
For realize above-mentioned purpose and other relevant purposes, the utility model provides a UV printer nozzle presses black jam-proof structure, including china ink jar, electric ink valve, UV china ink shower nozzle the bottom of china ink jar pass through the pipeline with the electric ink valve is connected, the electric ink valve pass through the pipeline with UV china ink shower nozzle is connected, the electric ink valve is connected with first three-way first port, first three-way second port with UV china ink shower nozzle is connected, first three-way third port is connected with the one end of a hollow china ink pipe, the other end of hollow china ink pipe is sealed.
Preferably, the other end of the hollow ink tube is sealed by a plug.
Preferably, the top of the ink tank is connected with a first port of a second tee joint through a pipeline, a second port of the second tee joint is connected with a pressure control valve, a third port of the second tee joint is connected with an electric air valve, the electric air valve is a normally open valve, and the electric air valve is connected with an ink pressing button.
Preferably, an air filter is arranged between the second tee joint and the ink tank.
Preferably, the pressure control valve is a constant pressure valve.
As described above, the utility model discloses following beneficial effect has: this UV printer nozzle presses black jam-proof structure is through a tee junction hollow ink pipe between electrographic valve and UV china ink shower nozzle, there is sealed air in the hollow ink pipe, the air is compressible, the air fluctuation that the micro-action caused such as the electrographic valve is opened or is closed like this can be absorbed or is released by this section hollow ink pipe, just so can not lead to the fact the influence to UV china ink shower nozzle, thereby can effectively place the mutual interference appearing between the shower nozzle, prevent that the condition of appearing analysing black in UV shower nozzle surface, make things convenient for operating personnel to press black operation simultaneously, and the waste of reducible ink.
