[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-3 As shown, this utility model provides a technical solution:

[0024] A preheating device for corrugated cardboard processing includes an operating table 1. A fixed support 2 is fixedly connected to the top of the operating table 1. Limiting grooves 3 are provided on both sides of the fixed support 2. An adjusting frame 4 is provided inside the operating table 1. The two ends of the adjusting frame 4 are slidably connected to the limiting grooves 3 respectively. A preheating roller 5 is rotatably connected between the two ends of the adjusting frame 4. An adjusting screw 6 is rotatably connected to the top of the adjusting frame 4. The adjusting screw 6 passes through the top of the fixed support 2 and is threaded to it. An adjusting knob 7 is fixedly connected to the top of the adjusting screw 6. When the operator places the corrugated cardboard between the preheating roller 5 and the preheating roller 8, and the distance between the preheating roller 5 and the preheating roller 8 needs to be adjusted, the operator rotates the adjusting knob 7, which drives the adjusting screw 6 to rotate. When the adjusting screw 6 rotates, it drives the adjusting frame 4 to move vertically, thereby realizing the adjustment of the distance between the preheating roller 5 and the preheating roller 8.

[0025] A preheating roller 8 is rotatably connected inside the fixed bracket 2. A motor 9 is fixedly connected to one side of the fixed bracket 2. The output end of the motor 9 is coaxially fixedly connected to one end of the preheating roller 8. A pulley 10 is rotatably connected to the side of the fixed bracket 2 away from the motor 9. The pulley 10 is fixedly connected to the other end of the preheating roller 8. When the motor 9 is started, the preheating roller 8 is driven to rotate. When the preheating roller 8 rotates, it cooperates with the preheating roller 5 to move the corrugated cardboard and preheat it at the same time. During the rotation of the preheating roller 8, the pulley 10 is driven to rotate.

[0026] Two mounting plates 11 are fixedly connected above the operating table 1. Cleaning roller 13 and cleaning roller 2 14 are rotatably connected between the two mounting plates 11. A pulley 2 12 is rotatably connected to the outer side of one of the mounting plates 11. A belt is fitted between pulley 10 and pulley 2 12. Gear 15 and gear 2 16 are rotatably connected to the outer side of the other mounting plate 11. Gear 15 and gear 2 16 are fixedly connected to cleaning roller 2 14 and cleaning roller 13 respectively. Gear 15 and gear 2 16 mesh. When pulley 10 rotates, it drives pulley 2 12 to rotate through the belt. When pulley 2 12 rotates, it drives cleaning roller 2 14 to rotate. During the rotation of cleaning roller 2 14, gear 15 drives gear 2 16 to rotate. Gear 2 16 drives cleaning roller 13 to rotate, thereby cleaning both sides of the corrugated cardboard.

[0027] Several support frames 17 are fixedly connected to the bottom of the control panel 1, and the support frames 17 support the control panel 1.

[0028] The working principle of this utility model is as follows:

[0029] First, the operator passes the corrugated cardboard between cleaning roller 13 and cleaning roller 24, and then places it between preheating roller 15 and preheating roller 28. When the distance between preheating roller 15 and preheating roller 28 needs to be adjusted, the operator turns the adjustment knob 7, which drives the adjustment screw 6 to rotate. As the adjustment screw 6 rotates, it causes the adjustment frame 4 to move vertically, thus adjusting the distance between preheating roller 15 and preheating roller 28 to accommodate corrugated cardboard of different thicknesses, offering good practicality. Next, the motor 9 is started, driving preheating roller 28 to rotate. As preheating roller 28 rotates, it works in conjunction with preheating roller 15 to move the corrugated cardboard... The preheating roller 8 moves while preheating the corrugated cardboard. During its rotation, the preheating roller 8 drives the pulley 10 to rotate. When the pulley 10 rotates, it drives the pulley 12 to rotate via a belt. When the pulley 12 rotates, it drives the cleaning roller 14 to rotate. During its rotation, the cleaning roller 14 drives the gear 16 to rotate via the gear 15. The gear 16 then drives the cleaning roller 13 to rotate, thereby cleaning both sides of the corrugated cardboard, removing dust and impurities, ensuring the quality of the corrugated cardboard, and preventing dust and impurities from adhering to the preheating roller 5 and the preheating roller 8.

[0030] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
