For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 and Figure 2 As shown, a water washing device of a digital printing machine includes a printing platform 10, a printing nozzle 20 and a water tank 30.

[0023] A moving guide belt 11 is wound around the printing platform 10 , and the moving guide belt 11 is a stepping moving guide belt, which is used to place the cloth on the moving guide belt 11 for feeding.

[0024] The print head 20 is disposed above the printing platform 10 and is used for printing the cloth placed on the moving guide belt 11 .

[0025] The water tank 30 is arranged below the printing platform 10 and along the width direction of the printing platform 10. The water tank 30 is provided with a first water inlet pipe 31, a second water inlet pipe 32, a first water absorbing sponge roller 33 and a second water absorbing sponge roller 34 arranged along the width direction of the water tank 30.

[0026] Among them, the first water inlet pipe 31 and the second water inlet pipe 32 are arranged in a front-to-back interval along the length direction of the water tank 30, and multiple first nozzles 311 and second nozzles 321 are vertically arranged on the first water inlet pipe 31 and the second water inlet pipe 32, which are used to spray water to clean the moving guide belt 11 at the bottom of the printing platform 10, and flush the printing color stains on the moving guide belt 11 into the water tank 30.

[0027] The first water-absorbing sponge roller 33 and the second water-absorbing sponge roller 34 are arranged at intervals along the length direction of the water tank 30 and close to the first nozzle 311. The upper ends of the first water-absorbing sponge roller 33 and the second water-absorbing sponge roller 34 are in contact with the bottom of the moving guide belt 11. The first water-absorbing sponge roller 33 and the second water-absorbing sponge roller 34 can first wipe and absorb the printing color stains left on the moving guide belt 11, and then the water sprayed by the first nozzle 311 and the second nozzle 321 can be used to fully clean the printing color stains, so that the moving guide belt 11 has a better cleaning effect during operation, which can effectively reduce the degree of printing color stains and improve the printing quality.

[0028] During specific operation: since the moving guide belt 11 is a step-by-step moving guide belt, at the moment when the moving guide belt 11 pauses in stepping, the first nozzle 311 and the second nozzle 321 spray diffused high-pressure water to increase the cleaning area, so that the moving guide belt 11 has a better cleaning effect during operation, which can effectively reduce the degree of color staining of the printing and improve the printing quality.

[0029] In this embodiment, the first nozzle 311 and the second nozzle 321 are both fan-shaped nozzles, which can increase the range of the nozzle spraying water and improve the cleaning area of ​​the moving guide belt 11.

[0030] In this embodiment, the number of the first nozzle 311 and the second nozzle 321 arranged on the first water inlet pipe 31 and the second water inlet pipe 32 is 20 respectively, so that the movable guide belt 11 can be fully cleaned, which can effectively reduce the degree of color staining of the printing and improve the printing quality.

[0031] In this embodiment, a drain pipe 35 is provided at the bottom of the water tank 30 for draining waste water in the water tank 30 .

[0032] In this embodiment, the bottom surface of the sink 30 is a slope that inclines from the high end to the low end, and the drain pipe 35 is located at the low end of the bottom surface of the sink 30. By tilting the bottom surface of the sink 30, waste water can be better discharged through the drain pipe 35, preventing excessive waste water from being retained in the sink 30.

[0033] In this embodiment, the first water inlet pipe 31 and the second water inlet pipe 32 are fixedly connected to the inner bottom of the water tank 30, and one end of the first water inlet pipe 31 and the second water pipe are connected to an external water inlet pipe for supplying water to the first water inlet pipe 31 and the second water inlet pipe 32.

[0034] The utility model provides a water washing device for a digital printing machine. Compared with the prior art, a water tank 30 is arranged below the printing platform 10 along the width direction of the printing platform 10, and a first water inlet pipe 31 and a second water inlet pipe 32 are arranged at intervals in front and back along the length direction of the water tank 30. The first water inlet pipe 31 and the second water inlet pipe 32 are vertically and spaced apart and arranged with a plurality of first nozzles 311 and a second nozzle 321 for spraying water toward the bottom of the moving guide belt 11 to strengthen the cleaning of the moving guide belt 11. At the same time, the water spraying mode of the first nozzle 311 and the second nozzle 321 is changed to a divergent water spraying mode, and the cleaning mode of the nozzle is changed from the previous linear cleaning to surface cleaning, which can effectively increase the cleaning area of ​​the moving guide belt 11, so that the moving guide belt 11 has a better cleaning effect during operation, can effectively reduce the color staining of the printing, and improve the printing quality.

[0035] In addition, by setting the bottom surface of the water tank 30 as a slope that tilts from the high end to the low end, the drain pipe 35 is located at the low end of the bottom surface of the water tank 30, which can more effectively facilitate the discharge of waste water in the water tank 30.

[0036] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.
