The clamping groove 320 is provided to facilitate cooperation with the clamping head 370 to form a limit to the hanger 31. The two sides of the limiting block 32 are each provided with a box body 35 fixedly connected with the outer wall of the shell 30. The box body 35 is internally hollow. A rotating shaft 36 is rotatably installed in the internal cavity of the box body 35. A connecting shaft 360 is coaxially keyed connected with the front and rear ends of the rotating shaft 36. The connecting shaft 360 is rotatably connected with the box body 35 and the shell 30, respectively. A vertical connecting block 37 is fixedly connected with the outer wall of the rotating shaft 36. A clamping head 370 is fixedly connected with the top end of the connecting block 37 and is clamped in cooperation with the clamping groove 320. The rotating shaft 36, the connecting block 37, the clamping head 370, and the push plate 38 are integrally formed. This design ensures the connection strength between the rotating shaft 36, the connecting block 37, the clamping head 370, and the push plate 38, and ensures the limiting strength of the limiting block 32. A metal spring 39 is further fixedly connected in the internal cavity of the box body 35 by bolts. One end of the metal spring 39 abuts against the connecting block 37. After the mounting rack 33 is installed in place, the clamping head 370 is clamped with the clamping groove 320, and the metal spring 39 provides an abutting force to ensure that the hanger 31 is stably connected with the shell 30 and does not fall off.

[0050] In the present embodiment, the cross-sectional shape of the shell 30 is in the shape of a mouth. The shell 30 is fixedly connected with the top of the frame body 2 by bolts. This mounting mode ensures that the air inlet part 3 is stably mounted on the frame body 2, provides a stable support frame for the multi-layer filter structure, and ensures that the structure is stable during the filtering process and does not shake or displace.

[0051] In the present embodiment, the two opposite end faces of the two hangers 31 are each provided with a plurality of insertion grooves 310. The two side outer walls of the mounting rack 33 are each fixedly provided with an insertion strip 330 clamped in cooperation with the insertion groove 310. Through the clamping cooperation between the insertion groove 310 and the insertion strip 330, the disassembly and assembly convenience of the mounting rack 33 is improved, thereby facilitating the maintenance of the filter layer 34 in the later stage.

[0052] In the present embodiment, the two opposite end faces of the two box bodies 35 are each provided with a through slot 350 at the bottom end. The outer wall of the rotating shaft 36 is further fixedly provided with a push plate 38. The push plate 38 passes through the through slot 350 and protrudes to the outside of the box body 35.

[0053] It should be noted that the preferred number of filter layers 34 in the present embodiment is three, and the multiple filter layers 34 are sequentially arranged from top to bottom as the primary filter layer, the medium filter layer, and the high-efficiency filter layer. The primary filter layer adopts a fiber filter screen structure with a larger pore size, which can quickly intercept large-particle impurities such as paper scraps and sand, thereby avoiding the subsequent filter structure from being blocked. The medium filter layer is made of electrostatic stationary material, which can effectively capture 0.5-10-micron small dust and pollen particles, further purifying the air. The high-efficiency filter layer is made of superfine glass fiber filter paper, which can accurately filter particles above 0.3 microns, including smoke and bacteria. The three filter layers are progressive, which improves the interception ability of different particle sizes of pollutants compared to a single filter screen, ensures the cleanliness of the air entering the drying device, effectively prevents impurities from adhering to the surface of the printed matter or interfering with the ink drying process, and guarantees the printing quality.

[0054] In specific use, the user first connects the power supply of the fan 20 and the electric heating tube 23, and the fan 20 and the electric heating tube 23 start to work. The operation of the fan 20 causes the external air to enter the shell 30 in an up-down permeable manner, and the air passes through the filter layers 34 fixed in the top openings of the multiple mounting racks 33 in sequence. Subsequently, the air enters the hollow cover 21, and under the action of the airflow generated by the fan 20, it is forced to flow through the multiple wave-shaped electric heating tubes 23 in the inner cavity of the cover 21. After the air fully absorbs the heat of the electric heating tubes 23, it becomes a hot airflow. Then, the hot airflow passes through the grid plate 24 in the bottom opening of the cover 21, is uniformly dispersed through the multiple air holes 240 of the grid plate 24, and is blown toward the surface of the printed matter conveyed by the motorized roller 10 in the groove of the base 1. The hot airflow fully contacts the ink on the surface of the printed matter, and through heat transfer, the solvent in the ink is quickly volatilized, achieving rapid and uniform drying of the ink on the printed matter.

[0055] When disassembling the hanging rack 31, the user first pushes the push plate 38 outside the box body 35 downward, which drives the rotating shaft 36 to rotate, and the rotating shaft 36 rotates in the box body 35 and the shell 30 through the connecting shaft 360. Subsequently, the connecting block 37 fixedly connected with the rotating shaft 36 and the clamping head 370 at the top synchronously rotate, the clamping head 370 is disengaged from the clamping groove 320 in the side wall of the limiting block 32, the limiting of the hanging rack 31 is released, and the hanging rack 31 and the mounting rack 33 can be taken out from the shell 30 synchronously. Next, the insertion slot 310 on the hanging rack 31 is inserted into the insertion slot 330 on both sides of the mounting rack 33, and the mounting rack 33 is pulled out from the hanging rack 31, thereby realizing the disassembly of the hanging rack 31 and the filter layer 34, and facilitating the cleaning or replacement of the filter layer 34.

[0056] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
