Specifically, a second motor 31 is fixedly provided outside the box 1. The output end of the second motor 31 is fixedly connected to one end of the printing roller 3 to drive the printing roller 3 to rotate, which will not be elaborated here. During implementation, the staff places the paper to be printed above the conveyor belt 22, and then starts the first motor 23. The first motor 23 drives one of the conveyor rollers 21 to rotate, and then drives the conveyor belt 22 to rotate. When the conveyor belt 22 conveys the paper between the printing roller 3 and the conveyor belt 22, the printing roller 3 prints the paper.

[0024] The hot air component 4 is connected and arranged at the top end of the box body 1, and on the side close to the discharge port 12. The output end of the hot air component 4 faces the conveying component 2. In this embodiment, the hot air component 4 includes an air box 41. A circulation fan 42 is fixedly arranged on the top surface inside the air box 41. A plurality of heating tubes 43 are fixedly arranged at the lower part of the air box 41. An air inlet 411 is opened at the top end of the air box 41, and an air outlet 412 is opened at the bottom end of the air box 41. By setting the hot air blown out by the hot air component 4, the surface of the paper after being printed by the printing roller 3 can be heated, and then the ink that has not yet solidified on the paper surface can be dried, that is, the drying speed of the ink on the surface of the printed paper is accelerated. It can prevent the unfixed ink from causing ink stains during subsequent transportation and storage, and at the same time prevent the unfixed ink from flowing out of the box body 1 and emitting waste gas, which affects human health.

[0025] The air suction port 5 is connected and arranged at the bottom of the box body 1 and at one end of the discharge port 12, and is used to discharge the waste gas generated during the ink drying process in the box body 1. The air suction port 5 is connected to the input end of the hot air component 4 (i.e., the air inlet 411 of the air box 41) through the purification component 6. Specifically, the input end and the output end of the purification component 6 are respectively connected to the output end of the air suction port 5 and the air inlet 411 of the hot air component 4 through pipelines 63. In this embodiment, the purification component 6 is fixedly arranged at the top end of the box body 1. The purification component 6 includes a purification box 61. A plurality of filter nets 62 are inserted into the purification box 61. The input end of the purification box 61 is connected to the air suction port 5, and the output end of the purification box 61 is connected to the air inlet 411 of the air box 41.

[0026] During implementation, start the plurality of heating tubes 43 and the circulation fan 42 at the lower part of the air box 41. The air blown out by the circulation fan 42 is heated by the plurality of heating tubes 43 and then blown onto the conveying component 2. At this time, the paper located on the conveying component 2 is heated, and then the ink that has not yet solidified on the paper surface is dried. The waste gas generated during the ink drying process in the box body 1 is discharged from the air suction port 5 and purified through the plurality of filter nets 62 in the purification box 61. It should be noted that the purified air still has the remaining temperature after being heated by the plurality of heating tubes 43. Since the output end of the purification component 6 is connected to the air inlet 411 of the air box 41, the heated air is circulated in this way, thereby avoiding waste of heat sources and reducing the enterprise operation cost.

[0027] The cleaning component 7 is arranged at the bottom inside the box body 1, on one side of the air suction port 5, and is rotationally connected to the box body 1, and is used to clean the waste paper scraps or other foreign objects adhered to the outer surface of the conveying component 2, so as to prevent the waste paper scraps from lifting the paper to be printed and causing printing abnormalities. At the same time, by arranging the cleaning component 7 on one side of the air suction port 5, it can prevent the waste paper scraps, dust, foreign objects, etc. swept out by the cleaning component 7 from flying into the upper part of the box body 1 and polluting the printed paper.

[0028] Please refer toFigure 3 As shown in the figure, in this embodiment, the cleaning assembly 7 includes a rotating roller 71 rotatably connected to the box body 1 and a plurality of bristles 72 uniformly fixed on the outer peripheral surface of the rotating roller 71. The bristles 72 are used to clean the outer surface of the conveyor belt 22. One side of the box body 1 is rotatably connected with a power unit 73 for driving the rotating roller 71 to rotate. Please refer to Figure 1 As shown in the figure, specifically, one end of the rotating roller 71 passes through the side wall of the box body 1 and extends to the outside of the box body 1, and a first gear 731 is fixedly sleeved thereon. A second gear 732 is fixedly sleeved on the conveyor roller 21 on one side of the conveying assembly 2 close to the rotating roller 71. The first gear 731 and the second gear 732 are meshed with each other.

[0029] During implementation, the first motor 23 drives one of the conveyor rollers 21 to rotate. Preferably, the first motor 23 directly drives the conveyor roller 21 on one side of the conveying assembly 2 close to the rotating roller 71 to make the transmission more stable. At this time, the conveyor roller 21 drives the second gear 732 and the first gear 731 meshed with the second gear 732 to rotate synchronously, so as to drive the rotating roller 71 of the cleaning assembly 7 to rotate without adding additional power. It should be noted that since the second gear 732 and the first gear 731 are meshed with each other, the rotation directions of the second gear 732 and the first gear 731 are opposite. Therefore, the rotating roller 71 rotates in the opposite direction to the conveying direction of the conveyor belt 22, so as to better clean the outer surface of the conveyor belt 22.

[0030] When the present utility model is specifically implemented, the staff places the paper to be printed on the conveyor belt 22, and then starts the first motor 23. The first motor 23 drives the conveyor roller 21 and the conveyor belt 22 to rotate accordingly to convey the paper to be printed. When the paper is conveyed below the printing roller 3, the printing roller 3 prints the paper. At this time, the hot air component 4 is started. The hot air blown out by the hot air component 4 can heat the surface of the paper after being printed by the printing roller 3, and then dry the ink that has not yet solidified on the paper surface, avoiding the outflow of the wet ink outside the box body 1 and emitting waste gas, which affects the health of people. At the same time, the waste gas generated during the drying process of the ink in the box body 1 is discharged to the purification component 6 through the air suction port 5 for filtration. The filtered air still has the residual temperature heated by the plurality of heating tubes 43. Therefore, the purification component 6 re-transmits the filtered air into the hot air component 4, and circulates in this way to avoid waste of heat sources and reduce the operating cost of the enterprise. At the same time, through the cleaning assembly 7, the waste paper scraps or other foreign matters adhered to the outer surface of the conveying assembly 2 are cleaned.
