[0002] A tunnel drying oven is an industrial device that uses heat conduction, convection, or radiation to continuously dry materials. It mainly consists of a heating system, a conveying system, and a control system. Its core function is to dehydrate or solidify materials through uniform heating, and it is widely used in industrial production.

[0003] When drying corrugated paper, heat is released through heating wires to evaporate the moisture contained inside the corrugated paper.

At the same time, the corrugated paper is heated to a high temperature and cannot be cooled and shaped in time. To solve the above problems, a continuous production drying tunnel oven for corrugated paper is needed. Utility Model Content

The output end of the motor 3 is fixedly connected to one end of the second friction roller 5. A heating, evaporation and cooling mechanism is disposed on the surface of the first friction roller 4.

[0021] By setting up a protective cover 2 and installing a pair of limit plates 7, heat insulation protection is provided. By setting up a motor 3, the second friction roller 5 is driven to rotate. By setting up a first stabilizing shaft 8 and a second stabilizing shaft 9, the corrugated paper body 6 is kept stable during transport. By setting up a heating, evaporation and cooling mechanism, the corrugated paper body 6 is heated and dried better, while also being cooled and shaped quickly.

[0022] In this utility model, reference Figure 2 The heating, evaporation and cooling mechanism includes a drive wheel 11 fixedly connected to the surface of the first friction roller 4, a drive shaft 14 rotatably connected to the inner wall of the protective cover 2, a driven wheel 13 fixedly connected to one end of the drive shaft 14, and a belt 12 tensioned on the surfaces of the drive wheel 11 and the driven wheel 13.

[0023] By setting the driving wheel 11, the rotation of the driving wheel 11 drives the driven wheel 13 to rotate through the belt 12, which in turn drives the drive shaft 14 to rotate.

[0024] In this utility model, reference Figure 3One end of the drive shaft 14 is fixedly connected to a first bevel gear 23, the upper surface of the protective cover 2 is rotatably connected to a first spur gear 22, the upper surface of the first spur gear 22 is fixedly connected to a second bevel gear 24, and the first bevel gear 23 meshes with the second bevel gear 24.

[0025] By setting the first bevel gear 23, the second bevel gear 24 and the first straight gear 22 are driven to rotate.

[0026] In this utility model, reference Figure 3 The inner wall of the protective cover 2 is rotatably connected to a fan blade 21, and the top end of the fan blade 21 is fixedly connected to a second spur gear 20, which meshes with the first spur gear 22.

[0027] By setting the fan blades 21, the heated corrugated paper body 6 is cooled and shaped by rotation.

[0028] In this utility model, reference Figure 3 and Figure 4 The inner wall of the protective cover 2 is fixedly installed with a plurality of first heating wires 25 and second heating wires 15. The second friction roller 5 and the second stabilizing shaft 9 are tensioned and fitted with a conveyor belt 18. The surface of the conveyor belt 18 is provided with a plurality of ventilation holes 19. The first heating wires 25 are located above the corrugated paper body 6, and the second heating wires 15 are located below the corrugated paper body 6.

[0029] By setting the first heating wire 25 and the second heating wire 15, the upper and lower surfaces of the corrugated paper body 6 are dried and shaped. By setting multiple ventilation holes 19, the second heating wire 15 can be used to dry and heat the contact surface between the corrugated paper body 6 and the conveyor belt 18.

[0030] In this utility model, reference Figure 1 and Figure 2 A pair of limiting plates 7 are fixedly connected to the inner wall of the protective cover 2. A third spur gear 17 is fixedly connected to the surface of the first friction roller 4. A fourth spur gear 16 is fixedly connected to the surface of the second friction roller 5. The third spur gear 17 meshes with the fourth spur gear 16. A controller 10 is fixedly installed on the surface of the protective cover 2.

[0031] By setting a pair of limit plates 7, the conveying of the corrugated paper body 6 is kept stable. By setting a third spur gear 17, which cooperates with the fourth spur gear 16, the first friction roller 4 and the second friction roller 5 are driven to reverse relative to each other. By setting a controller 10, the start and stop of the motor 3 and the heating stability of the first heating wire 25 and the second heating wire 15 are controlled.

[0032] Working principle: The corrugated paper body 6 is placed between the first friction roller 4 and the second friction roller 5, and between the first stabilizing shaft 8 and the second stabilizing shaft 9. At this time, the lower surface of the corrugated paper body 6 is in contact with the upper surface of the conveyor belt 18. The motor 3 is started, and the output end of the motor 3 drives the second friction roller 5 to rotate. The second friction roller 5 drives the fourth spur gear 16 to rotate, and the fourth spur gear 16 drives the third spur gear 17 and the first friction roller 4 to rotate, so that the first friction roller 4 and the second friction roller 5 rotate in opposite directions. The second friction roller 5 drives the second stabilizing shaft 9 to rotate through the conveyor belt 18. The corrugated paper body 6 is continuously conveyed under the action of the conveyor belt 18. When the corrugated paper body 6 rotates, the lower surface of the corrugated paper body 6 is in contact with the upper surface of the conveyor belt 18. When the paper body 6 moves above the multiple first heating wires 25 and second heating wires 15, it is dried and heated. The first friction roller 4 drives the drive wheel 11 to rotate. The drive wheel 11 drives the driven wheel 13 to rotate through the belt 12. The driven wheel 13 drives the drive shaft 14 to rotate. The drive shaft 14 drives the first bevel gear 23 to rotate. The first bevel gear 23 drives the second bevel gear 24 and the first spur gear 22 to rotate. The first spur gear 22 drives the second spur gear 20 and the fan blade 21 to rotate. The diameter of the first spur gear 22 is larger than the diameter of the second spur gear 20, so as to achieve a speed change effect. The rotation of the fan blade 21 cools and shapes the dried corrugated paper body 6.
