[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The embodiment of the present application discloses a corrugated cardboard drying device.

[0037] Example 1

[0038] Reference Figure 1-4A corrugated cardboard drying device comprises a drying box 1, and an inlet and an outlet of the corrugated cardboard are arranged on both sides of the drying box 1. A blower mechanism 6 for blowing air to the holes on both sides of the corrugated cardboard and an exhaust mechanism 7 for exhausting air are arranged at relative positions on both sides of the inner wall of the drying box 1, so that the air inside the side holes of the corrugated cardboard can flow and circulate to improve the drying effect. The blower mechanism 6 and the exhaust mechanism 7 have the same structural dimensions and the same fixing method. A drying mechanism 8 is fixed on both sides of the upper and lower ends of the inner cavity of the drying box 1. A heating box 3, a blast box 4 and a drying box 5 are fixed on the upper end of the drying box 1. The drying mechanism 8, the heating box 3, the blast box 4 and the drying box 5 are fixed on the upper end of the drying box 1. The bellows 4 and the drying box 5 are both configured according to the prior art, and the technical solution is a conventional configuration, so their structures are not described in detail. The heating box 3 and the blower box 4 are connected and fixed by a pipeline, and the blower box 4 and the drying box 5 are connected and fixed by a pipeline to realize the flow of air. The upper ends of the air duct 66 of the blower mechanism 6 and the air duct 66 of the exhaust mechanism 7 are both connected and fixed with a conveying pipe 2. The conveying pipe 2 connected to the air duct 66 of the blower mechanism 6 is connected and fixed to the heating box 3, and the conveying pipe 2 connected to the upper end of the air duct 66 of the exhaust mechanism 7 is connected and fixed to the drying box 5. Both conveying pipes 2 pass through and are fixed on the side wall of the drying box body 1.

[0039] Through the above arrangement, the drying mechanism 8 also sprays the dry air generated by the external heating device onto the surface of the wet corrugated cardboard to achieve preliminary drying of the corrugated cardboard. Subsequently, the high-temperature and humid air inside the drying box 1 is fully dried. Subsequently, the blower box 4 is powered on to work and conveys the dry air inside the drying box 5 to the heating box 3 through the pipeline, thereby generating negative pressure inside the drying box 5. Then, the air inside the air duct 66 of the exhaust mechanism 7 is extracted through the conveying pipe 2. Then, the humid air inside the drying box 1 and the side holes of the corrugated cardboard is extracted through the air nozzle 690 of the exhaust mechanism 7. Then, the humid air inside the side holes of the corrugated cardboard flows, so that other dry air can enter the holes to accelerate the drying of the corrugated cardboard. At the same time, the drying box 5 can dry the incoming humid air and then it can be re-discharged into the drying box 1 through the blower box 4.

[0040] At the same time, the dried gas is reheated by the heating box 3 to make its high temperature and then transported to the air duct 66 of the blower mechanism 6 through the transmission pipe 3, and then the dry high-temperature gas is sprayed out by the air nozzle 690 of the blower mechanism 6. Since the air nozzle 690 is aligned with the side holes of the corrugated cardboard, the high-temperature dry gas can be blown into the holes to realize the gas circulation inside the holes, thereby accelerating the drying of the inside of the corrugated cardboard and improving the drying efficiency.

[0041] Reference Figure 2-4The hair dryer mechanism 6 includes a rectangular connecting plate 61 fixed by screws to the middle of one end of the inner wall of the drying box body 1. The middle of one side of the connecting plate 61 is fixed to the fixed end of the electric push rod 63. The telescopic end of the electric push rod 63 is fixed to the middle of one side of the fixing frame 64. The air duct 66 of the exhaust mechanism 7 exhausts air from the holes on the other side of the corrugated cardboard. A plurality of air nozzles 690 are fixed in an array and connected to the surface of the air duct 66 of the hair dryer mechanism 6 and the air duct 66 of the exhaust mechanism 7 on the opposite side. The air nozzle 690 is preferably conical to achieve gas gathering. The plurality of air nozzles 690 are connected to the air duct 66 of the exhaust mechanism 7 and the inner cavity of the air duct 66 of the hair dryer mechanism 6. A plurality of air nozzles 690 are located on both sides of the gap between the two drying mechanisms 8 and are opposite to each other. The hair dryer mechanism 6 also includes a telescopic rod 62 fixed with the connecting plate 61 on both sides of one end of the electric push rod 63. The telescopic end of the telescopic rod 62 is welded to the surface of the fixed frame 64. The fixed frame 64 is provided with a longitudinal groove on the side away from the telescopic rod 62. A slider 69 is provided in the longitudinal groove for longitudinal sliding. One end of the slider 69 is fixed to the surface of the movable frame 65. The movable frame 65 is provided with a groove on the side away from the slider 69. One end of the slider 69 abuts against the inner wall of the groove and can slide. The air duct 66 is fixed in the groove, and the two ends of the air duct 66 are located between the two guide wheels 67.

[0042] Through the above arrangement, when the electric push rod 63 is energized, its telescopic end can be extended and retracted to drive the movable frame 65 to move horizontally through the fixed frame 64, thereby driving the air duct 66 and the air nozzle 690 to move. This arrangement can make the guide wheel 67 abut against both sides of the corrugated cardboard to achieve a clamping effect so that the corrugated cardboard can be adjusted to a moving position, thereby making the air nozzle 690 maintain a suitable distance from the side of the corrugated cardboard to improve the blowing and exhausting effect inside the hole, thereby accelerating the air flow inside the hole on the side of the corrugated cardboard and accelerating the drying. The telescopic rod 62 is arranged to play a supporting role, and the telescopic end of the telescopic rod 62 can move with the movement of the fixed frame 64.

[0043] Reference Figure 5 Through holes are provided on both sides of the upper side wall of the movable frame 65, and fastening bolts 68 are movably passed through the through holes. The rod of the fastening bolt 68 is provided with threads, and the rod of the fastening bolt 68 is threadedly connected with the internal threaded hole in the middle of the slider 69 and the internal threaded hole on the lower side wall of the movable frame 65.

[0044] Through the above arrangement, the fastening bolt 68 is rotated and the slider 69 can be driven to slide longitudinally in the slot of the fixing frame 64 through its rod thread, so that the longitudinal position of the air nozzle 690 can be adjusted so that the air nozzle 690 can be aligned with the side of the corrugated cardboard. At the same time, the head of the fastening bolt 68 is away from the stem of the upper end of the fixing frame 64 and extends to the upper end of the fixing frame 64.

[0045] Reference Figure 3 , 5The two ends of the movable frame 65 on one side of the air duct 66 are movably interspersed with rotating shafts, and the rotating shafts movably penetrate the middle of the guide wheel 67, and the surface of the guide wheel 67 protrudes from the end surface of the air nozzle 690.

[0046] Through the above arrangement, the guide wheel 67 rolls on the side of the corrugated cardboard so that the distance between the air nozzle 690 and the side of the corrugated cardboard is always consistent.

[0047] Among them, the device also includes switches, power supplies, wires and other devices, which are not the main technologies and will not be described in detail.

[0048] The implementation principle of a corrugated cardboard drying device in an embodiment of the present application is as follows: the corrugated cardboard is inserted into the drying box 1 and is located between the two drying mechanisms 8, the air blowing mechanism 6 and the exhaust mechanism 7. Then, the electric push rod 63 pushes the fixed frame 64 to move and then drives the moving frame 65 to move through the fastening bolts 68 and the slider 69, thereby causing the guide wheel 67 of the air blowing mechanism 6 and the guide wheel 67 of the exhaust mechanism 7 to move toward each other and abut against the side of the corrugated cardboard.

[0049] Subsequently, the blowing mechanism 4 is powered on, and the air nozzle 690 of the exhaust mechanism 7 extracts the gas inside the holes on the side of the corrugated cardboard and transports it to the drying box 5 through the conveying pipe 2 for drying. Subsequently, the dried gas enters the heating box 3 through the blowing mechanism 4 for heating, and then the high-temperature dry gas is transported to the air duct 66 of the blowing mechanism 6 through the conveying pipe 2. The air nozzle 690 of the blowing mechanism 6 then sprays the gas into the holes on the side panel of the corrugated cardboard, thereby allowing the humid gas inside the holes to flow and be discharged.

[0050] Through the above arrangement, the device can discharge the moist gas inside the corrugated cardboard and then allow dry high-temperature gas to enter the holes inside the corrugated cardboard, thereby drying the corrugated cardboard in real time, thereby improving the drying effect of the corrugated cardboard and effectively saving drying time.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
