Description

UV printer shower nozzle pressure china ink jam-proof mechanism

Technical Field

The utility model relates to a UV printer specifically is a UV printer nozzle presses black jam-proof mechanism.

Background

The UV 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-level printing on the surfaces of T-shirts, sliding doors, cabinet doors, sliding doors, glass, plates, various labels, crystals, PVC, acrylic, metal, plastics, stones, 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 existing solution is to manually wipe the nozzles, but one person does not wipe four nozzles in time at a 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.
