The magnet block 407 is magnetically connected to the magnetic strip 401. The suction strip 401 and the limiting clamp 408 are fixedly connected to the bottom right side of the limiting slider. The end of the air delivery pipe 405 away from the top right side of the air pump 404 is fixedly connected to the front right side of the airbag 406. The limiting slider has a through groove inside, the diameter of which matches the diameter of the limiting sliding rod 403. The limiting sliding seat 402 and the limiting sliding rod 403 work together to limit the movement of the limiting slider, ensuring stable forward and backward movement and achieving stable limiting. The limiting slider has a sliding torque groove inside, the area of ​​which matches the side area of ​​the limiting sliding seat 402. The limiting slider is slidably connected to the surface of the limiting sliding seat 402. The top of the limiting connecting block 304 has a rectangular groove, the area of ​​which matches the bottom area of ​​the connecting slider 303.

[0026] The adjustable heating assembly 3 includes a connecting L-shaped frame 301, a top plate 302, a connecting slider 303, a limiting connecting block 304, a connecting rectangular plate 305, a heating rod 306, a hydraulic telescopic rod 307, a heating box 308, and an air outlet telescopic pipe 309. The connecting L-shaped frame 301 is fixedly connected to the bottom of the processing table 1. The top plate 302 is fixedly connected to the top of the connecting L-shaped frame 301. The connecting slider 303 is fixedly connected to the bottom of the top plate 302. The limiting connecting block 304 is slidably connected to the bottom surface of the connecting slider 303. The hydraulic telescopic rod 307 is fixedly connected to the bottom of the top plate 302. The limiting connecting block 304... The bottom of the hydraulic telescopic rod 307 is fixedly connected.

Then, adjust the distance between the front and rear limiting clamps 408 so that the limiting clamps 408 contact the front and rear ends of the cardboard. This limits the heating effect during the feeding process. During adjustment, hold the limiting slider against the surfaces of the limiting sliding seat 402 and the limiting sliding rod 403 and let them slide closer to each other. Continue sliding until the limiting clamps 408 contact the front and rear ends of the cardboard. When contact is made, start the air pump 404 and work with the air delivery pipe 405 to input gas into the air bag 406, causing the air bag 406 to inflate. The impact causes the magnet 407 to move upward until it presses against the bottom of the magnetic strip 401. After the magnet 407 and the magnetic strip 401 come into contact, they can be magnetically locked together. Together with the pressure, they help to fix the limiting clamp 408. This can adapt to the transmission of cardboard, limit the cardboard, and ensure the heating effect. After the cardboard is transmitted inward, it can come into contact with the heating rod 306 at the bottom of the top plate 302 for initial heating. It is then transmitted to the right until it reaches the bottom of the heating box 308 and the air outlet telescopic pipe 309. Then, the heating wire inside the heating box 308 is activated to heat the air, which is then blown out through the air outlet telescopic pipe 309 for hot air drying. The two work together to increase heating efficiency and make it easy to use.
