In one embodiment, as shown in Figures 5 and 6, the second support bolt 931 is provided above the second wiping bracket 91, the lower end of the second supporting spring 932 is in contact with the second wiping bracket 91, and the second supporting bolt 931 is disposed above the second wiping bracket 91. The upper end of the spring 932 is in contact with the second wiping shaft 92, and the second supporting spring 932 can hold up the second wiping shaft 92 upward.

In one embodiment, as shown in Figure 5, the nozzle cleaning device also includes a flushing nozzle 53. The flushing nozzle 53 is arranged on the frame 1, and the flushing nozzle 53 is located between the first wiping component 4 and the second wiping component 9. The flushing nozzle 53 is used to flush the wiping cloth 100 between the first wiping component 4 and the second wiping component 9 .

Specifically, by arranging the flushing nozzle 53, the slightly contaminated wiper cloth 100 that has been used once can be flushed to flush out the ink or ink residue on the wiper cloth 100, thereby improving the efficiency of the wiper cloth used at the second wiper assembly 9. 100% cleanliness. During specific use, only one of the first wiping component 4 and the second wiping component 9 can be used, that is, the nozzle is only cleaned at the first wiping component 4 or the second wiping component 9. In this use state , there is no difference between a nozzle cleaning device with two wiping components and a nozzle cleaning device with only the first wiping component 4, and the usage effect is the same.

In the specific implementation process, as shown in FIG. 5 , the collection tray 7 extends below the flushing nozzle 53 and the second wiping assembly 9 , that is, the collection tray 7 can collect the water used to flush the wiper 100 and the ink falling from the nozzle. Collect to prevent these liquids from contaminating other parts, especially to prevent these liquids from contaminating unused wipers 100, thereby effectively ensuring the cleanliness of unused wipers 100.

The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application shall be included in the protection of the present application. within the range.
