[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0021] Please refer to Figure 1 、 2 As shown in FIGS. 3 and 4, the present utility model provides a technical solution: a drying machine for printing printed matter, including: a drying box 1, the drying box 1 is a cavity with a box door on one side, and a plurality of material conveying rollers 6 are installed inside the drying box 1 along an S-shaped path. Heat dissipation holes 7 are provided on the outer side of the material conveying rollers 6. The printed matter is wound around the material conveying rollers 6 to realize the drying process while conveying; a conveying frame 3 is fixedly connected to one side of the drying box 1, a conveying part is arranged at the top of the conveying frame 3, and a heat dissipation pipe 5 for drying is arranged in the middle of the conveying part; a box cover 9 is detachably installed on the top of the conveying frame 3 through a buckle. A rolling wheel 13 for fixing the printed matter is slidably arranged up and down inside the conveying frame 3. An electric heating wire 14 is installed inside the box cover 9, and filter boxes 2 are installed on the tops of both the box cover 9 and the drying box 1 to filter out air odors.

[0022] It should be noted that in the present utility model, the box cover 9 is lifted upward at one end, the printed matter is placed conveniently at the bottom of the rolling wheel 13, and it is dried by blowing air through the electric heating wire 14 and the fan 10. Then, the distribution route of one end of the material conveying roller 6 is wound around the outer side of the material conveying roller 6, so that the printed matter walks in an S-shaped path inside the drying box 1, and one end of it passes out from the end of the drying box 1 and is wound around the winding mechanism, and is pulled by the winding mechanism to drive the printed matter to move forward. During this period, the fan 10 blows hot air through the electric heating wire 14 to dry the printed matter inside the box cover 9. The rolling wheel 13 presses both sides to tighten the printed matter, and the heat dissipation pipe 5 dissipates part of the hot air, which is convenient for drying from its bottom. Then the printed matter is conveyed into the drying box 1. According to needs, the electric heating plate 8 is controlled to work. When the electric heating plate 8 does not work, the drying box 1 can slowly cool the printed matter to reduce the surface temperature. When the printed matter inside the drying box 1 needs to be reheated, it is dried and heated through the electric heating plate 8, which improves the drying speed, and through automatic control, the manual intervention is reduced.

[0023] Please refer to Figure 1 、 2 As shown in FIGS., a plurality of electric heating plates 8 are fixedly connected inside the drying box 1 in an inclined manner, and the electric heating plates 8 are arranged along the conveying direction of the printed matter.

[0024] It should be noted that the electric heating plate 8 of the present utility model is arranged along the printing material conveying direction, so that the printing material can be continuously heated when passing through the air drying box, ensuring continuous heat supply and uniform drying of the printing material; when the printing material enters the air drying box, it is first directly heated by the heat emitted by the electric heating plate 8; due to the inclined installation of the electric heating plate 8, the hot air flows along the inclined direction and naturally covers the entire surface of the printing material, making the heat distribution more uniform; during the movement of the printing material, it continuously passes through multiple electric heating plates 8, and each plate provides a certain amount of heat. This continuous heat supply helps to quickly achieve the required drying effect, especially suitable for printing materials with strong water absorption or large thickness.

[0025] Please refer to Figure 4 As shown in the figure, the conveying part includes a conveyor 4 installed on the top of the conveying frame 3. The heat dissipation pipe 5 is installed in the middle of the conveyor 4. Through holes are provided on the outer side of the heat dissipation pipe 5. Multiple through holes are provided on the conveyor belt of the conveyor 4. Inside the box cover 9, a heating box 12 with an opening at the bottom is fixedly connected. The electric heating wire 14 is fixedly connected inside the heating box 12. Ventilation openings are provided at the top of both the box cover 9 and the heating box 12. A fan 10 is installed at the position of the box cover 9 corresponding to the ventilation opening. Both the air drying box 1 and the box cover 9 are communicated with the bottom of the filtering box 2. An activated carbon net is arranged inside the filtering box 2. A blower 11 is fixedly connected to one side of the filtering box 2. Both the material conveying roller 6 and the heat dissipation pipe 5 are fixedly connected to the output end of the blower 11 through rotary joints.

[0026] It should be noted that in the present utility model, the fan 10 blows air towards the electric heating wire 14, and the air heated by the electric heating wire 14 blows towards the printing material. During this period, the conveyor 4 drives the printing material to be conveyed forward. The blower 11 sends the filtered hot air inside the box cover 9 into the heat dissipation pipe 5, and then it is dispersed through the through holes of the heat dissipation pipe 5 to the bottom of the printing material, thereby realizing simultaneous drying from top and bottom. The blower 11 at the top of the air drying box 1 extracts the air from the air drying box 1, filters it, and then sends it back into the air drying box 1. An activated carbon filter screen is arranged inside the filtering box 2, which can adsorb harmful gases, odors, and dust particles in the air.

[0027] Please refer to Figure 3 As shown in the figure, a lifting rod 15 is fixedly connected to the top of the rolling wheel 13. The lifting rod 15 is slidably connected to the box cover 9. A return spring 16 is sleeved on the outer side of the lifting rod 15 and at the bottom of the box cover 9.

[0028] It should be noted that the lifting rod 15 of the present utility model has a rectangular or elliptical structure. Under the action of the rolling wheel 13, the printing material is pressed and straightened on the top of the conveyor 4. Under the action of the return spring 16, it can be applicable to printing materials of different thicknesses.
