However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] like Figures 1 to 5 The main structure of the paperboard printing drying device shown is two mounting plates 1 for paperboard drying and conveying and a drying box 6 for paperboard drying. A conveyor belt 2 is rotatably installed between the two mounting plates 1. Two mounting strips 3 are symmetrically and fixedly connected to the top surface of the mounting plates 1. Guide plates 4 are fixedly connected to the top surface of the mounting strips 3. Limiting plates 5 are fixedly connected to the ends of the two guide plates 4. The limiting plates 5 are parallel to the conveying direction of the conveyor belt 2. Thanks to the setting of the guide plates 4, limiting plates 5 and other structures, the paperboard can be further guided, so that the paperboard is located in the middle of the conveyor belt 2, thereby improving the drying effect of the paperboard.

[0029] A connecting rod 7 is fixedly connected to the top surface inside the drying oven 6. Multiple fans 8 are fixedly connected to the bottom of the connecting rod 7. A heating plate 9 is fixedly installed on the top surface inside the drying oven 6. Thanks to the setting of the heating plate 9 and the fans 8, air can be effectively drawn into the interior of the drying oven 6 through the rectangular hole 10 by the fans 8. At the same time, the air is heated as soon as it enters the interior of the drying oven 6 and blown onto the surface of the cardboard.

[0030] The top surface of the drying oven 6 has a rectangular hole 10, and a rectangular frame 11 is sealed inside the rectangular hole 10. A filter screen 12 is fixedly installed inside the rectangular frame 11. An installation groove 14 is opened inside the rectangular frame 11. A locking block 13 is slidably connected inside the installation groove 14, and a push spring 15 is fixedly connected inside the installation groove 14. The end of the push spring 15 is fixedly connected to the locking block 13. The inner wall of the rectangular hole 10 and the locking block 13 have corresponding slots. Thanks to the setting of the rectangular hole 10, the rectangular frame 11 and the filter screen 12, air can be drawn into the interior of the drying oven 6 through the rectangular hole 10 by multiple fans 8. At the same time, the air is filtered by the rectangular frame 11 and the filter screen 12 installed inside the rectangular hole 10, thereby preventing dust in the air from being drawn into the interior of the drying oven 6 and adhering to the surface of the cardboard, thus greatly improving the quality of the finished cardboard.

[0031] The side wall of the card block 13 is symmetrically fixedly connected with the limiting block 16, and the inner wall of the mounting groove 14 is symmetrically opened with two limiting grooves. The two limiting blocks 16 symmetrically fixedly connected to the side wall of the card block 13 are slidably connected to the inside of the two limiting grooves opened in the inner wall of the mounting groove 14. Thanks to the setting of the limiting block 16, the sliding direction of the card block 13 can be effectively limited, and the stability of the card block 13 during sliding can be further improved.

[0032] The outer wall of the rectangular frame 11 is connected to the mounting groove 14 and has a strip-shaped hole. The side wall of the locking block 13 is symmetrically fixed with a pull rod 17. The pull rod 17 fixed to the side wall of the locking block 13 slides through the strip-shaped hole and extends to the outside of the rectangular frame 11. Thanks to the setting of the pull rod 17, by moving the pull rod 17, the locking block 13 is moved into the mounting groove 14 and the rectangular frame 11 is removed from the limit. In this way, the rectangular frame 11 and the filter screen 12 can be removed from the rectangular hole 10, so that the dust and other accumulated on the surface of the filter screen 12 can be cleaned.

[0033] Multiple rectangular grooves 18 are provided on the opposite side of the two limiting plates 5. Rollers 19 are rotatably installed inside the multiple rectangular grooves 18. Thanks to the setting of the rollers 19, the friction between the cardboard and the limiting plate 5 is greatly reduced, so that the cardboard is limited firstly, but it will not affect the cardboard from moving synchronously with the conveyor belt 2.

[0034] Working principle

[0035] In use, the printed cardboard to be dried is first placed on the top surface of the conveyor belt 2. Then, the cardboard is guided by two guide plates 4 and a limiting plate 5, so that the cardboard is located in the middle of the conveyor belt 2. Then, the fan 8 is started to draw air into the drying chamber 6 through the rectangular hole 10 on the top surface of the drying chamber 6. At this time, the heating plate 9 is started to heat the air. At the same time, the air is filtered by the filter screen 12 fixedly connected inside the rectangular frame 11 installed inside the rectangular hole 10. Then, the heated air is sprayed onto the surface of the cardboard below by the fan 8. When too much dust accumulates on the filter screen 12, the pull rod 17 is moved. By pulling the pull rod 17, the locking block 13 is retracted into the mounting groove 14, and the rectangular frame 11 is released from its limiting position. In this way, the rectangular frame 11 and the filter screen 12 can be removed from the rectangular hole 10, so that the dust accumulated on the surface of the filter screen 12 can be cleaned.
