Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a nozzle moisturizing device of a digital printing machine. Background Art

[0002] Digital printing machine is a non-contact printing method, which sprays ink on the printed material through the inkjet nozzle, so that the printed material has patterns or texts.

[0003] After the print head finishes printing, the residual ink on the print head is likely to solidify, and the ink will block the nozzle hole of the print head, which is easy to affect the next printing effect. Therefore, after stopping printing, the print head needs to be cleaned. At the same time, in order to avoid the volatilization of the ink inside the print head and the formation of caking, the print head also needs to be moisturized.

[0004] The existing Chinese patent with announcement number CN220548842U discloses a nozzle moisturizing device for a digital printing machine, which belongs to the technical field of printing equipment, and includes a closed bowl that is raised and lowered by a driving member, and the closed bowl is respectively equipped with a water inlet pipe and a water outlet pipe, and the water inlet pipe and the water outlet pipe are provided with a control member for controlling the conduction of the water inlet pipe and the water outlet pipe, and an absorbent cotton block is provided at the bottom of the closed bowl, and the closed bowl is provided with an actuator that makes the absorbent cotton block contact with the nozzle.

[0005] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the device sprays gas through the air nozzle to drive the absorbent cotton block to move and repeatedly contact the surface of the nozzle, and the water inside the closed bowl will flow out from the air nozzle, causing waste, which needs to be improved; therefore, in view of the above problems, a nozzle moisturizing device for a digital printing machine is proposed.
