The conveyor belt driven roller 26 and the conveyor belt driving roller 25 are respectively rotatably connected to the left and right ends inside the conveyor belt 15. The conveyor belt driving roller 25 is fixedly connected with the driving mechanism 2. The conveyor belt driven roller 26 is fixedly connected with the limit shaft 4; The air extraction mechanism includes an air pump 11. The air pump 11 is fixedly connected to the positions on the front and rear sides of the main body 1 of the printing device.

The air extraction mechanism is fixedly connected with the hollow pipe 17 through the quick connector 10.

[0031] The air holes 16 formed in the conveyor belt 15 are connected through the hollow tube 17, the quick connector 10, the air pipe 12, and the air pump 11. The air pump 11 can continuously extract air, so that the position of the air holes 16 can always maintain negative pressure. Thus, during the process of conveying the printed paper, positioning can be carried out, effectively preventing the problem that the ink on the printed paper is not dry and the paper wrinkles during the conveying process, which affects the beauty of the printed content on the paper. There are two conveyor belts 15 in total. The first limiting groove 13 and the second limiting groove 14 are connected. The hollow tube 17 is located inside the second limiting groove 14. The upper end surfaces of the conveyor belt 15 and the medium conveying plate 9 are arranged on the same horizontal plane, which can limit the positions on the lower sides of both ends of the paper during the paper conveying process. The driving mechanism 2 includes a driving motor 201. The top end of the main shaft of the driving motor 201 is fixedly connected with a first gear 202.

Fixing holes 304 are formed inside the fixed blocks 303. The motor housing 301 is fixedly connected to the medium conveying plate 9 through standard bolts passing through the fixing holes 304, which can protect the driving mechanism 2 during the operation of the device. The limiting shaft 4 and the front and rear ends of the driving shaft 203 are rotatably connected to the limiting grooves 302 formed at the front and rear ends of the motor housing 301 through bearings 205, and the driving mechanism 2 is arranged inside the protection mechanism 3, which can improve the stability of the conveyor belt 15 during operation;

[0032] On the front and back sides of the left end of the medium conveying plate 9, a fan box 18 and a heating box 5 are respectively provided. At the end of the bottom of the fan box 18 and the heating box 5 close to the medium conveying plate 9, a buffer pad 22 is fixedly connected. Positioning holes 23 are provided inside the lower ends of the fan box 18, the heating box 5 and the buffer pad 22. The fan box 18 and the heating box 5 are fixedly connected to the front and rear ends of the medium conveying plate 9 through fixing bolts 7 passing through the positioning holes 23. The upper ends of the fan box 18 and the heating box 5 are fixedly connected through a wind guiding mechanism 8, which can further dry the printing ink on the paper during actual use and can remove the ink smell around the printing device and on the paper after printing, thereby improving the air quality around the printing device; The wind guiding mechanism 8 includes a positioning housing 801. The lower end of the positioning housing 801 is fixedly connected with a limiting bracket 803. The front and rear ends of the limiting bracket 803 are both slidably connected with a wind guiding plate 802. The upper end of the wind guiding plate 802 is slidably connected with the positioning housing 801, which can adjust the distance between the fan box 18 and the heating box 5 during actual use; Inside the upper end of the fan box 18, a fan 21 is provided. The rear end of the fan box 18 is fixedly connected with an activated carbon plate protective shell 19. Inside the activated carbon plate protective shell 19, an activated carbon plate 20 is provided, and the activated carbon plate protective shell 19 and the fan box 18 are communicated. Inside the heating box 5, an electric heating wire 24 is provided. Inside the upper end of the heating box 5, a dust filter screen 6 is fixedly connected, which can remove the ink smell.

[0033] Working process: When the device is in use, it is powered on by an external power supply. During the use of an energy-saving and environment-friendly printing device: First, the staff places the paper inside the printing device main body 1 for printing. The printed paper is conveyed out through the medium conveying plate 9 to complete printing. During the process of the paper being conveyed through the medium conveying plate 9, the air pump 11 will work and continuously extract air. At this time, negative pressure will appear inside the air holes 16. At the same time, driven by the conveyor belt 15, the paper can be conveyed from the right end of the medium conveying plate 9 to the left. During the conveying process, the conveyor belt 15 can continuously adsorb the lower end of the printed paper, which can ensure that the conveyor belt 15 will not bend during the conveying process (that is, it can ensure the flatness of the paper). Such a setting can ensure the flatness of the paper during the process of being conveyed through the medium conveying plate 9 in actual use, thereby effectively preventing the problem that the ink on the just-printed paper is not completely dry and affects the printed content, and thus ensuring the beauty of the printed content on the paper;

[0034] Moreover, during the paper transportation process after printing, when the printed paper passes through the position below the air guiding mechanism 8, the fan 21 can suck the hot air near the electric heating wire 24 and the surrounding air together to the position inside the fan box 18. When the hot air flows into the fan box 18, it will pass through the position above the printed paper. In this way, the set hot air can further dry the printed paper, and at the same time, adsorb the ink smell on the printed paper together with the hot air into the fan box 18. The hot air entering the fan box 18 is discharged through the activated carbon plate 20. This setting can adsorb and eliminate some of the ink on the printed paper and the ink near the device, improve the air quality near the printing equipment, and at the same time, the extendable air guiding mechanism 8 can be used to install the structure for further drying the paper ink and adsorbing the ink smell on printing devices of different models, with a wide range of applications.

The descriptions of the above examples are only used to help understand the method and its core idea of the present invention. The above is only the preferred implementation mode of the present invention. It should be noted that due to the limited nature of written expression and the objectively infinite specific structures, for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements, retouches or changes can be made, or the above technical features can be combined in an appropriate manner; these improvements, retouches, changes or combinations, or directly applying the concept and technical solution of the invention to other occasions without improvement, should all be regarded as the protection scope of the present invention.
