[0025] The effect achieved by the entire embodiment 1 is that after the pattern is printed on the surface of the carton material using the printer body 1, it is conveyed outwardly through the conveyor belt 12. During the process, the high-resistance heating wire 32 and the exhaust fan 407 are started. At this time, the high-resistance heating wire 32 will convert electrical energy into thermal energy to heat and dry the ink on the surface of the carton, thereby evaporating the moisture in the ink that is not completely dried. After the exhaust fan 407 is started, the air in the filter box 401 will be extracted. At this time, a negative pressure will be formed at the lower end of the connecting pipe 23 connected to the filter box 401, so that the air near the heating box 31 is sucked into the filter box 401 through the connecting pipe 23. During the process, the accelerated air flow will further improve the drying efficiency of the ink on the surface of the carton, and the toxic gases generated during the drying process will be discharged through the connecting pipe 23. The toxic gas is drawn into the filter box 401. After entering the filter box 401, it will be filtered by multiple filter plates 406 and then discharged from the exhaust port of the exhaust fan 407 to the air in the working area, thereby solving the problem that the toxic gas generated during the ink drying process will pollute the environment and affect the health of the workers. The mounting frame 11 is mainly used to install the conveyor belt 12 and the mounting plate 2. The mounting plate 2 is mainly used to install the shell 22 and other mechanisms. The conveyor belt 12, the mounting frame 11 and the mounting plate 2 cooperate to form a channel sealed on all sides, so that the toxic gas generated during the ink drying process can smoothly enter the filter box 401 through the connecting pipe 23. The filter plate 406 can be made of suitable materials according to actual conditions, such as an activated carbon plate made of activated carbon material.

[0026] Embodiment 2, as Figure 1-Figure 5As shown, the bottom of the box cover 402 is fixedly connected with an insertion rod 403 near the four corners, the outer surface of the insertion rod 403 slides through the top of the filter box 401 and extends to the inside, the front and rear outer surfaces of the box cover 402 are fixedly connected with handles, and a hair dryer 21 is installed on the top of the mounting plate 2 near the front side.

[0027] The effect achieved by the entire embodiment 2 is that when the carton above the conveyor belt 12 passes under the high-resistance heating wire 32 and the ink on the surface is dried and then reaches the position below the hair dryer 21, the hair dryer 21 is started to accelerate the flow rate of air around the carton, which can play a role in quickly cooling it. This design solves the problem that the carton is directly air-dried without drying it, which easily causes the ink to spread and affects the quality of the carton. By starting the electric push rod 3, the height of the heating box 31 and the high-resistance heating wire 32 can be adjusted, so as to adjust the distance between the heat source and the carton according to actual conditions, thereby improving the use effect. By holding the handles on both sides of the box cover 402 and pulling it upward, the U-shaped plate 404 can be exposed from the filter box 401, and then the filter plate 406 can be directly pulled out from the slot 405 for replacement, which is easy to operate. The box cover 402 can be accurately installed on the top of the filter box 401 under the action of the insertion rod 403, and will not detach from the top of the filter box 401 under the action of its own weight and the weight of the exhaust fan 407.

[0028] Working principle: After the printing machine body 1 is used to print the pattern on the surface of the carton material, it is transported outward through the conveyor belt 12. During the process, the high-resistance heating wire 32 and the exhaust fan 407 are started. At this time, the high-resistance heating wire 32 will convert electrical energy into thermal energy to heat and dry the ink on the surface of the carton, so that the moisture in the ink that is not completely dried will evaporate, and after the exhaust fan 407 is started, the air in the filter box 401 will be extracted. At this time, a negative pressure will be formed at the lower end of the connecting pipe 23 connected to the filter box 401, so that the air near the heating box 31 is drawn into the filter box 401 through the connecting pipe 23. During the process, the accelerated air flow will further improve the drying efficiency of the ink on the surface of the carton, and the toxic gas generated during the drying process will be drawn into the filter box 401 through the connecting pipe 23. After the toxic gas enters the filter box 401, it will The air is filtered by multiple filter plates 406 and then discharged from the exhaust port of the exhaust fan 407 to the air in the working area, thereby solving the problem that the toxic gases generated during the ink drying process will pollute the environment and affect the health of the workers. In addition, when the carton above the conveyor belt 12 passes under the high-resistance heating wire 32 and the ink on the surface is dried and then reaches the position below the hair dryer 21, the hair dryer 21 is started to accelerate the flow rate of air around the carton, which can quickly cool it down. This design solves the problem that the carton is easily diffused and affects the quality of the carton if it is directly air-dried without drying it. By holding the handles on both sides of the box cover 402 and pulling it upward, the U-shaped plate 404 can be exposed from the filter box 401, and then the filter plate 406 can be directly pulled out from the slot 405 for replacement, which is easy to operate.
