[0039] Working principle and advantages of the present invention: When the drying and cooling device for corrugated paper production is used, the working process is as follows:

[0040] like Figure 1 , Figure 2 and Figure 4 As shown, the corrugated paper to be dried is placed on each layer plate 9 on the material rack 42, and then the material rack is placed on the belt conveyor 2 at equal intervals in sequence, and the motor 12 is started to work, so that the motor 12 drives the gear column 13 to rotate, so that the gear column 13 drives the shaft rod 15 and the groove roller 18 and gear 2 20 thereon to rotate through gear 1 14. When the slider 19 slides in the annular groove 2 35, gear 2 20 is meshed and connected with gear 3 21, and gear 1 14 is disengaged from gear 4 27. At this time, the connecting rod 1 23 is close to the pin rod 36 and the sleeve ring 39 drives the connecting pipe 11 to move up through the connecting rod 2 38, and is not connected to the air intake pipe 10 directly below it, so that the belt conveyor 2 can smoothly transport the material rack 42, and at this time, each group of door panels 6 is in an open state to facilitate the material rack 42 to enter and exit the box cover 3.

[0041] When gear 2 20 is meshed with gear 3 21, gear 2 20 drives gear 3 21 to rotate, so that gear 3 21 drives roller 7 to rotate through pulley assembly 2, and then roller 7 drives belt conveyor 2 to work, so that belt conveyor 2 transports the material rack 42 to be dried into the drying chamber 5, and at the same time transports the dried material rack 42 in the drying chamber 5 to the cooling chamber 4, and at the same time moves the cooled material rack 42 in the cooling chamber 4 out of the box cover 3.

[0042] As the groove roller 18 rotates, when the slider 19 enters the annular groove 1 32 from the connecting groove 1 33 in the annular groove 2 35, the gear 2 20 is disengaged from the gear 3 21, and the gear 1 14 is meshed with the gear 4 27. At this time, the gear 3 21 cannot drive the belt conveyor 2 to operate through the pulley assembly 22 and the roller shaft 7, and the air inlet pipe 10 on the material rack 42 just in the drying chamber 5 and the cooling chamber 4 is located directly below the corresponding connecting pipe 11, and the slider 19 enters the annular groove 1 32 from the connecting groove 1 33 in the annular groove 2 35. The slider 19 pushes the groove roller 18 in the annular groove 1 32 through the connecting groove 1 33. Figure 1 , Figure 2The shaft 15 drives the connecting rod 1 23 away from the pin 36, so that the connecting rod 2 38 drives the connecting pipe 11 downward through the collar 39, so that the connecting pipe 11 is connected with the corresponding air inlet pipe 10, and at the same time, the connecting rod 1 23 drives the corresponding gear 5 26 to rotate through the rack 24, and then the gear 5 26 drives the corresponding door panel 6 to rotate, so that each set of door panels 6 is matched as shown in FIG. Figure 5 As shown in the state, both ends of the box cover 3 are closed and the interior is divided into a cooling chamber 4 and a drying chamber 5.

[0043] When gear 14 and gear 4 27 are meshed, the gear column 13 drives gear 4 27 to rotate through gear 14, so that gear 4 27 drives the hot air blower 28 and the cold air blower 30 to work at the same time, so that the hot air blower 28 conveys dry hot air to the corresponding connecting pipe 11 through the hot air pipe 29, and then the connecting pipe 11 conveys the dry hot air to each pipe column 8 through the air inlet pipe 10 on the material rack 42 in the drying chamber 5, and then blows the dry hot air through the air holes on the side wall of the pipe column 8 to dry the corrugated paper on the layer plate 9. At the same time, the cold air blower 30 conveys dry cold air to the corresponding connecting pipe 11 through the cold air pipe 31, and then the connecting pipe 11 conveys the dry cold air to each pipe column 8 through the air inlet pipe 10 on the material rack 42 in the cooling chamber 4, and then blows the corrugated paper on the layer plate 9 through the air holes on the side wall of the pipe column 8 to cool the corrugated paper, thereby realizing the simultaneous drying and cooling of the corrugated paper, greatly reducing labor intensity and time, and improving work efficiency.

[0044] When the slider 19 passes through the connecting groove 2 34 from the annular groove 1 32 and enters the annular groove 2 35, as described above, the gear 2 20 is meshed and connected with the gear 3 21, and the gear 1 14 is disengaged from the gear 4 27, and the cycle is repeated, thereby realizing automatic conveying of the material rack 42, and automatically drying and cooling the corrugated paper on the material rack 42, thereby greatly improving the work efficiency.
