In addition, the transmission speed of the drying belt 3 and the supply of hot air can be adjusted as needed, thereby adjusting the drying intensity of the drying device, thereby adapting to various work requirements;

[0028] A plurality of spray heads 412 are fixedly arranged on the top of the cleaning seat 41, and the plurality of spray heads 412 are connected to an external spray mechanism through a spray pipe. A collecting tank 413 is provided at the bottom of the cleaning seat 41, and the collecting tank 413 is connected to an external waste collection mechanism through a sewage collecting pipe.

[0029] Two collecting plates 15 are obliquely arranged at the discharge port 12, and the output ends of the two collecting plates 15 are respectively located below the two driving rollers 2, and the two driving rollers 2 pull the drying belt 3 to form an inclined surface, and an air guide groove 16 is fixedly arranged on the drying box 1, and the output end of the air guide groove 16 is aligned with the inclined surface;

[0030] An air supply pipe 17 is fixedly provided on the top of the drying box 1, two exhaust pipes 18 are symmetrically provided on both sides of the drying box 1, and a V-shaped material guide plate is also fixedly provided in the drying box 1, and the output end of the material guide plate is connected to the input end of the exhaust pipe 18;

[0031] A drying slot 19 is fixedly provided at the bottom of the drying box 1 , the drying belt 3 passes through the drying slot 19 , and the air guide slot 16 and the drying slot 19 are connected to the air supply pipe 17 through two air guide pipes respectively.

[0032] During implementation, the logistics that need to be dried are conveyed to the drying belt 3 through the feeding mechanism 5, and the drying belt 3 is driven by the driving roller 2 to rotate to convey the materials. In this process, the air supply pipe 17 is used to convey hot air into the drying box 1, and then the materials are dried. At the same time, when the materials are conveyed along the drying belt 3, some fine materials will pass through the drying belt 3 during the drying process. At this time, the guide plate is used to convey the fallen materials to the exhaust pipe 18, and a filter is set at the air guide pipe 18 to further collect the fallen materials to prevent the materials from polluting the internal environment of the drying box 1. When the materials are dried, the materials are conveyed to the discharge port 12 with the rotation of the drying belt 3 and fall onto the collecting plate 15 located above the discharge port 12 under the action of their own gravity. Then, some of the materials attached to the drying belt 3 are conveyed to the air guide groove 16, and then the hot air in the air supply pipe 17 enters the air guide groove 16 through the air guide pipe and blows down the materials attached to the drying belt 3, and The waste is collected by the collecting plate 15 below the discharge port 12, and then the drying belt 3 is conveyed to the two cleaning components 4, and the two cleaning components 4 are respectively located on the two sides of the drying belt 3. When the drying belt 3 enters the cleaning tank 411, the spray head 412 is used to spray warm water or a neutral detergent on the drying belt 3, and then the cleaning roller brush 43 is used to clean the drying belt 3, and then the stubborn stains remaining on the drying belt 3 are cleaned. Then the cleaned waste is collected by the collecting tank 413 and conveyed to the waste collection mechanism through the sewage collecting pipe. After the drying belt 3 passes through the two cleaning components 4, that is, both sides of the drying belt 3 are cleaned, the drying belt 3 is conveyed to the drying tank 19, and then the hot air in the air supply pipe 17 is guided to the drying tank 19 by the air guide pipe, and then the cleaned drying belt 3 is dried to prevent corrosion caused by residual water stains on the drying belt 3, thereby realizing self-cleaning of the drying belt 3, effectively extending the service life of the drying belt 3 and improving the drying efficiency.

[0033] In this embodiment, Figure 4 and Figure 6 The adjusting mechanism 42 includes a C-shaped adjusting rod 421, a hydraulic telescopic rod 2 is arranged between the adjusting rod 421 and the cleaning seat 41, two supporting rings 422 are fixedly arranged on the adjusting rod 421, and the cleaning roller brush 43 is rotatably arranged between the two supporting rings 422;

[0035] The drying box 1 is provided with a sliding groove 13 for the support ring 422 to slide and a sealing groove 14 for the sealing partition 423 to slide.

[0036] In particular, the cleaning component 4 works periodically, that is, the drying belt 3 is cleaned regularly. When the drying belt 3 does not need to be cleaned, the hydraulic telescopic rod 2 is used to drive the adjusting rod 421 to slide, thereby further driving the cleaning roller brush 43 to slide away from the drying belt 3, thereby preventing the drying belt 3 from being in contact with the cleaning roller brush 43 for a long time, thereby preventing damage to the drying belt 3 and the cleaning roller brush 43. In addition, the support ring 422 and the sealing baffle 423 are provided so that the driving motor that drives the cleaning roller brush 43 to rotate can be fixed on the sealing baffle 423, thereby preventing the rotation of the cleaning roller brush 43 from being affected by the sliding of the adjusting mechanism 42. At the same time, the sealing baffle 423 can further block the drying box 1 during the sliding of the adjusting mechanism 42.

[0037] In this embodiment, Figure 7 The correcting mechanism 6 includes a fixed plate 61, a correcting ring 62 and a correcting rod 63, wherein the fixed plate 61 is fixedly arranged on the drying box 1, the correcting ring 62 is slidably arranged on the drying box 1 and is connected to the fixed plate 61 through a hydraulic telescopic rod, the correcting rod 63 is rotatably arranged on the correcting ring 62, and a distance sensor is embedded in the correcting ring 62.

[0038] During implementation, the distance sensor is used to monitor the distance between the drying belt 3 and the correcting ring 62, and then the position of the drying belt 3 is determined. When the drying belt 3 deviates during the transmission process, the two correcting mechanisms 6 are used to correct the drying belt 3, that is, different tensions are applied to the drying belt 3 through the two correcting rods 63, thereby driving the drying belt 3 to deviate and return to the correct position, thereby further ensuring the normal operation of the drying belt 3 and the drying device as a whole.
