Since the bottom of the peripheral side of the guide roller 23 is tightly fitted with the top of the cleaning cloth 24, when the guide roller 23 is driven to rotate by the machine body 1, the cleaning cloth 24 is reversely driven at its bottom, and then the surface of the cleaning cloth 24 cleans the guide roller 23, and the bottom of the cleaning cloth 24 is guided to the inside of the cleaning water tank 26 by the guide roller 27, so that the cleaning water tank 26 maintains a certain degree of cleanliness, thereby avoiding the decrease of cleanliness and cleaning effect caused by long-term cleaning of the guide roller 23;

[0036] Step 2: At the same time, since there is fine fluff at the bottom of the inner wall of the impurity removal rack 28, the sliding plate 29 drives the roller 3 to apply pressure to the inner side of the cleaning cloth 24 under the action of the spring 4, so that the outer side of the cleaning cloth 24 (that is, the side that cleans the guide roller 23) fits on the fluff, and the fluff retains impurities and a certain amount of water, and the impurities and water left behind will fall along the impurity removal rack 28, and a water collecting tank can also be set at the bottom of the support frame 21 for recovery.

[0037] Compared with the related art, the guide roller cleaning mechanism of a digital printing machine provided by the utility model has the following beneficial effects:

[0038] The output end of the driving motor 5 rotates in the same direction as the guide roller 23, and the two transmission rollers 25 drive the cleaning cloth 24 on their peripheral sides to rotate. Since the bottom of the peripheral side of the guide roller 23 is tightly fitted with the top of the cleaning cloth 24, when the guide roller 23 is driven to rotate by the machine body 1, the cleaning cloth 24 is driven in the reverse direction at its bottom, and then the surface of the cleaning cloth 24 cleans the guide roller 23. The structure is simple and practical, and the guide roller can be cleaned while the machine is running, thereby improving the use efficiency.

[0039] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model.
