Description

Technical Field

[0001] This utility model relates to the technical field of cardboard processing equipment, and in particular to a continuous production drying tunnel oven. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is made of at least one layer of corrugated paper and one layer of linerboard bonded together, and has good elasticity and extensibility. Corrugated cardboard is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods.

[0003] During the reprocessing of corrugated cardboard, it is necessary to dry the cardboard. However, in the current drying equipment on the market, water vapor tends to accumulate on the inner top of the drying device, resulting in low drying efficiency and slow speed for the corrugated cardboard.

[0022] Furthermore, a discharge port is provided on the front side of the insulated box 1, and a discharge port is provided on the rear side of the insulated box 1. The conveyor belt 7 extends into the interior of the insulated box 1 through the discharge port and the discharge port.

[0023] Furthermore, the tensioning assembly includes a fixed plate 8, guide rods 9, a connecting plate frame 10, and an electric telescopic rod 11. The fixed plate 8 is fixedly installed on both sides of the discharge port. Two guide rods 9 are slidably installed on the fixed plate 8. The connecting plate frame 10 is fixedly installed at the front ends of the two guide rods 9. The electric telescopic rod 11 is fixedly installed on the front side of the fixed plate 8. The free end of the electric telescopic rod 11 is fixedly installed on the rear side of the connecting plate frame 10. The driven roller 6 is rotatably installed on both sides of the connecting plate frame 10. When the electric telescopic rod 11 is activated, the free end of the electric telescopic rod 11 pushes the connecting plate frame 10 and the driven roller 6 forward. The forward movement of the driven roller 6 can tension the conveyor belt 7.

[0024] Furthermore, the blowing unit includes a suction fan 13, a suction pipe 14, and an exhaust pipe 16. The suction fan 13 is fixedly installed on the top outer wall of the insulation box 1. One end of the suction pipe 14 is fixedly connected to the input end of the suction fan 13, and the other end of the suction pipe 14 passes through the top of the insulation box 1 and communicates with the interior of the insulation box 1. One end of the exhaust pipe 16 passes through one side of the insulation box 1 and communicates with the interior of the insulation box 1. This can drive the air inside the insulation box 1 to circulate and accelerate the drying speed of the cardboard. When the suction fan 13 is started, the suction fan 13 draws hot air from inside the insulation box 1 through the suction pipe 14. The hot air enters the sealed box 15 and the exhaust pipe 16 through the suction fan 13 and re-enters the interior of the insulation box 1 through the sealed box 15 and the exhaust pipe 16 to circulate and dry the cardboard.

[0025] Furthermore, the dehumidification component includes a sealed box 15 and a honeycomb mesh panel 17. The sealed box 15 is fixedly installed on the top outer wall of the insulation box 1.

The other end of the air outlet pipe 16 passes through the rear side of the sealed box 15 and communicates with the interior of the sealed box 15. When hot air comes into contact with the honeycomb mesh panel 17 in the sealed box 15, the water vapor in the hot air will accumulate on the surface of the honeycomb mesh panel 17 to form water droplets. The water droplets fall into the bottom of the sealed box 15 and are finally discharged through the drain pipe 18, so as to avoid the water vapor in the furnace from affecting the drying efficiency of the corrugated paper.

[0026] Furthermore, a drain pipe 18 is fixedly installed on one side of the sealed box 15, and the drain pipe 18 is equipped with a valve.

[0027] Furthermore, the heating wires 12 are evenly distributed above and below the conveyor belt 7.

[0028] Working principle: By activating the electric telescopic rod 11, the free end of the electric telescopic rod 11 pushes the connecting plate frame 10 and the driven roller 6 forward. The forward movement of the driven roller 6 tensions the conveyor belt 7, placing the cardboard onto the conveyor belt 7. Activating the motor 4 causes the output shaft of the motor 4 to drive the drive roller 5 to rotate. The rotation of the drive roller 5 moves the conveyor belt 7 and the cardboard, transporting the cardboard into the insulated box 1. Activating the heating wire 12 generates heat to dry the cardboard. Activating the suction fan... 13. The suction fan 13 draws hot air from inside the insulation box 1 through the suction pipe 14. The hot air enters the sealed box 15 and the exhaust pipe 16 through the suction fan 13. When the hot air comes into contact with the honeycomb mesh panel 17 in the sealed box 15, the water vapor in the hot air will accumulate on the surface of the honeycomb mesh panel 17 to form water droplets. The water droplets fall into the bottom of the sealed box 15 and are finally discharged through the drain pipe 18. The dried hot air re-enters the interior of the insulation box 1 through the sealed box 15 and the exhaust pipe 16 to circulate and dry the cardboard.
