Description
Technical Field
The invention relates to the technical field of digital jet printing, in particular to a moisturizing device of a digital printing machine and the digital printing machine comprising the moisturizing device.
Background
Digital printing machines are increasingly used in printing processes on products such as cloth. For example, chinese patent publication No. CN107901626A discloses a digital printing machine with double-sided jet printing.
The digital printing machine is a device for spraying ink drops onto a printing stock through a spray head. When the digital printing machine stops working, the spray nozzle does not work any more, the spray hole of the spray nozzle is exposed in the air, the ink in the spray hole is dried, namely the solvent of the ink is evaporated, and the residual solute is remained in the spray hole. This affects the smoothness of the ink in the next inkjet printing, further affecting the inkjet printing accuracy. And the nozzle holes can be seriously and even blocked, so that the spray head cannot work normally.
To solve this problem, there are generally two solutions. One is to clean the orifice before using the spray head. The spray head is allowed to empty for a certain time, and residual dried ink in the spray holes is washed away by utilizing the ink jet of the spray head, so that the aim of cleaning is fulfilled. The problem with this solution is that a large amount of ink is wasted, increasing the cost, and not being environmentally friendly. Moreover, if the downtime is long and the ink is dried seriously, the ink is difficult to clean and even cannot be cleaned at all.
The other scheme is that a moisturizing cover plate is buckled on the spray head after the machine is stopped, and the spray head is sealed so as to reduce the evaporation of ink. The operation of this solution is cumbersome, especially for the digital printing machine with two opposite spray heads as disclosed in patent application No. CN107901626A, a complicated structure needs to be designed to fasten the cover plate to the spray head, so that after the machine is stopped, the spray heads with two opposite sides can be separated by a large distance, and then the cover plate can be fastened to the spray head, which makes the structure quite complicated, and the precision of the spray head is difficult to guarantee when it is reset. In addition, when the cover plate is buckled on the sprayer, the sprayer is easy to damage due to improper operation.
