Description
Technical Field
The invention belongs to the field of printing, and particularly relates to a spray head structure.
Background
In ink jet printing technology, a nozzle and an ink path system form a circuit for printing ink. In the ink jet printing production process, the nozzle blockage is easily caused by the precipitation of ink (such as white ink) with larger particles.
If the prior application discloses an anti-blocking ink-jet printer nozzle (with the application number of CN 201820661647.2), the anti-blocking ink-jet printer nozzle comprises a main nozzle, an anti-blocking needle, a connecting rod, a side pipe and a sliding block; the anti-blocking needle is arranged in the cavity of the main spray head, the connecting rod is arranged in the side pipe, the anti-blocking needle is fixedly connected with the sliding block through the connecting rod, and the side pipe is communicated with the main spray head and fixed on the side pipe wall of the main spray head; the sliding block is the same with the inner chamber shape of side pipe, and sliding connection has an opening in the inner chamber of lateral wall on the side pipe. The nozzle avoids the blockage of the nozzle by inserting the anti-blocking needle into the position of the ink outlet of the nozzle. However, firstly, the structure of the nozzle is complex, the effect of avoiding the nozzle blockage can be realized only by manual operation, and the nozzle can only dredge the sediment at the ink outlet of the nozzle, and the ink sediment at other positions cannot be processed.
Disclosure of Invention
The invention aims to provide a nozzle with a single-color ink circulation ink path, which increases the fluidity of ink in the nozzle by arranging the ink circulation ink path and prevents the nozzle from being blocked due to the deposition of the ink with larger particles in the nozzle ink path.
Another object of the present invention is to provide a head having a single-color ink circulation path, which has an anti-blocking function without manual operation.
In order to achieve the above object, the present invention has the following technical means.
A shower nozzle with monochrome ink circulation ink route, the shower nozzle includes shower nozzle upper cover, shower nozzle base, characterized by that, the said shower nozzle upper cover has circulation ink routes, the said circulation ink route includes upper ink inlet, upper ink outlet, circulation channel and two lower ink outlets, said upper ink inlet, upper ink outlet set up in the upper side of the said shower nozzle upper cover, two said lower ink outlets set up in the lower side of the said shower nozzle upper cover, the said circulation channel is set up in the said shower nozzle upper cover, said upper ink inlet, circulation channel, upper ink outlet form the circulation path used for circulating the ink; the nozzle base is provided with two base channels for ink-jet printing corresponding to one circulating ink path, the nozzle upper cover is arranged on the upper side of the nozzle base, and the two lower ink outlets are communicated with the two base channels. In this shower nozzle, when the ink is exported from the shower nozzle, can be earlier from going up ink inlet department entering shower nozzle, some ink gets into from two base passageway one ends that ink outlet department got into the shower nozzle base down behind the circulation channel, and export through the base passageway other end, realize shower nozzle inkjet process, another part ink is then discharged from last ink outlet after through the circulation route, get back to outside china ink bucket or ink horn, realize the circulation of the inside ink of input to shower nozzle, in order to increase the mobility of the inside ink of shower nozzle, prevent that the inside phenomenon that appears because of the shower nozzle jam that the bigger ink of granule subsides cause of circulation ink path of shower nozzle. And the anti-blocking function does not need manual operation, so that the anti-blocking device is more convenient.
