The following describes the embodiments according to the overall structure of the present utility model.

[0021] Refer to Figures 1 to 5, in the embodiment of the present utility model, a hot air dryer for a corrugated cardboard printing and slotting machine includes: an operating table 1, a drive box 2 is installed on the side of the operating table 1, a dryer 3 is fixedly connected above the drive box 2, an air outlet pipe 4 is fixedly connected below the dryer 3, four groups of symmetric screws are installed below the air outlet pipe 4 to install an air outlet 5, an air volume adjustment plate 6 is movably connected to the side of the air outlet 5, a side plate 7 is fixedly connected to the side of the air outlet pipe 4, a telescopic rod 8 is fixedly connected above the side plate 7, a lifting plate 9 is fixedly connected above the telescopic rod 8, a lifting frame 10 is fixedly connected to the side of the lifting plate 9, a fixed frame 14 is fixedly connected inside the air outlet pipe 4, a first movable frame 11, a second movable frame 12 and a third movable frame 13 are installed between the lifting frame 10 and the fixed frame 14, a dust scraping plate 15 is fixedly connected above the lifting plate 9, a dust scraping head 16 is fixedly connected to the side of the dust scraping plate 15. The air volume adjustment plate 6 includes a plug board adapted to the internal gap of the air outlet 5, and the plug board is adapted to the sliding groove opened on the side of the air outlet 5. The numbers of the side plate 7, the telescopic rod 8, the lifting plate 9, the lifting frame 10 and the fixed frame 14 are all set to two groups. Between each group of the lifting frame 10 and the fixed frame 14, folding and lifting activities are carried out through two groups of the first movable frame 11, the second movable frame 12 and the third movable frame 13. When the motor in the drive box 2 is started, it first drives the blower in the dryer 3 to rotate. The function of the blower is to inhale external air and send it into the heater. The air inhaled by the blower enters the heater part. The heater is equipped with electric heating elements such as spiral electric heating wires. These electric heating elements generate heat after being energized. When the air passes through the heater, it exchanges heat with the electric heating elements, so that the air is heated to the required temperature. In this process, the air passes evenly through the inner side and the outer side of the electric heating wire to ensure high heat exchange efficiency and less loss of air volume and air pressure. The heated air is output through the air outlet pipe 4 of the hot air blower to form high-temperature hot air. Then the hot air is transmitted through the air outlet pipe 4 to the air outlet 5. The multiple holes of the air outlet 5 ensure that the hot air can evenly cover the surface of the corrugated cardboard box to be dried. In order to cope with cartons of different materials, thicknesses or printing requirements, the air volume adjustment plates 6 which are movably connected are arranged on the side of the air outlet 5. These air volume adjustment plates 6 cooperate with the sliding grooves inside the air outlet 5 through the plug boards, and the opening degree can be adjusted according to needs, so as to accurately control the air volume of each air outlet and achieve a more refined drying effect. The structures such as the telescopic rod 8, the lifting plate 9 and the lifting frame 10 installed on the side plate 7 constitute a liftable dust scraping system. By adjusting the length of the telescopic rod 8, the lifting plate 9 and the dust scraping plate 15 fixedly connected thereto can be driven to move up and down. The dust scraping head 16 on the side of the dust scraping plate 15 can effectively remove the dust and impurities on the surface of the cardboard box during the moving process, ensuring the printing effect and creating a cleaner surface environment for hot air drying at the same time. Between the lifting frame 10 and the fixed frame 14 inside the air outlet pipe 4, they are connected to each other through the first movable frame 11, the second movable frame 12 and the third movable frame 13 to form a folding and lifting structure. This design not only ensures the stability of the dust scraping plate 15 during the lifting process, but also makes the whole system more compact, flexible, easy to adjust and maintain.

[0022] Referring to Figure 5 , an activity slot 17 is formed on the side of the drive box 2. A spring 18 is fixedly connected inside the activity slot 17. A grooving roller 19 is fixedly connected below the spring 18. An auxiliary roller 20 is provided at the other end of the side of the drive box 2. A conveyor belt 21 is provided above the operating table 1. The number of the activity slot 17 and the spring 18 are both set to two groups, symmetrically arranged on both sides of the grooving roller 19. In the activity slot 17 provided on the side of the drive box 2, the spring 18 and the grooving roller 19 cooperate. When the cardboard box passes by along with the conveyor belt 21, the grooving roller 19 closely adheres to the surface of the cardboard box under the action of the spring force, moves along with it and completes the grooving operation. This design makes the grooving process both stable and has a certain adaptability, and can adapt to cardboard boxes of different thicknesses. The continuous movement of the conveyor belt 21 not only improves the production efficiency, but also ensures that the residence time of the cardboard box in the dryer is consistent, so as to obtain a uniform drying effect.

[0023] Referring to Figure 1 and Figure 5 , a long support plate 22 is fixedly connected below the operating table 1, and a short support plate 23 is fixedly connected at the other end below the operating table 1. The number of the long support plate 22 and the short support plate 23 are both set to two groups, symmetrically arranged on both sides below the operating table 1. The long support plate 22 and the short support plate 23 provided below the operating table 1 provide a stable support foundation for the entire hot air dryer. This symmetrically distributed support structure not only enhances the overall stability of the equipment, but also facilitates installation and debugging.

[0024] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0025] The working principle of the present utility model is as follows: First, the motor in the drive box 2 starts, driving the dryer 3 to work and generating high-temperature hot air. The hot air is then transmitted through the air outlet pipe 4 to the air outlet 5. The multiple holes at the air outlet 5 ensure that the hot air can evenly cover the surface of the corrugated cardboard box to be dried. To cope with cardboard boxes of different materials, thicknesses or printing requirements, adjustable air volume plates 6 are movably connected to the side of the air outlet 5. These adjustment plates cooperate with the sliding grooves inside the air outlet 5 through plug plates, and the opening degree can be adjusted as needed, so as to precisely control the air volume of each air outlet and achieve a more refined drying effect. Structures such as the telescopic rod 8, lifting plate 9 and lifting frame 10 installed on the side plate 7 constitute a liftable ash scraping system. By adjusting the length of the telescopic rod 8, the lifting plate 9 and the ash scraping plate 15 fixedly connected thereto can be driven to move up and down. The scraping heads 16 on the side of the ash scraping plate 15 can effectively remove the dust and impurities on the surface of the cardboard box during the movement, ensuring the printing effect and creating a cleaner surface environment for hot air drying at the same time. Between the lifting frame 10 and the fixed frame 14 inside the air outlet pipe 4, they are interconnected through the first movable frame 11, the second movable frame 12 and the third movable frame 13 to form a folding and lifting structure. This design not only ensures the stability of the ash scraping plate 15 during the lifting process, but also makes the entire system more compact, flexible, easy to adjust and maintain. In the movable groove 17 provided on the side of the drive box 2, the spring 18 cooperates with the grooved roller 19. When the cardboard box passes by along the conveyor belt 21, the grooved roller 19 closely adheres to the surface of the cardboard box under the action of the spring force, moves along with it and completes the grooving operation. This design makes the grooving process stable and has a certain adaptability, and can adapt to cardboard boxes of different thicknesses. The continuous movement of the conveyor belt 21 not only improves the production efficiency, but also ensures that the residence time of the cardboard box in the dryer is consistent, so as to obtain a uniform drying effect. The long support plate 22 and the short support plate 23 provided under the operating table 1 provide a stable support foundation for the entire hot air dryer. This symmetrically distributed support structure not only enhances the overall stability of the equipment, but also facilitates installation and debugging.

[0026] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its utility model concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
