[0014] 1. The height of the slide can be adjusted according to the trajectory of the slide rail by the electric push rod. Driven by the slide, the pressure roller can press the side of the cardboard to prevent the cardboard from warping during the preheating process. The belt can be used to keep the pressing continuous when the pressure roller is pressing, and at the same time improve the pressing effect. The movable groove can be used to adjust the distance between the two supports, so that the equipment can be used for cardboard of different sizes. This method can prevent uneven shrinkage caused by excessively fast evaporation of moisture, thus preventing the cardboard from bending.

[0015] 2. The top of the cardboard can be heated by the drive roller, which moves the cardboard. When the two supports get close to each other, they will compress the spring. Under the control of the spring force, the distance between the electric heating rollers can be kept the same. The heating tube can heat the heat conduction plate, thereby preheating the bottom of the cardboard. The drive roller can improve the preheating efficiency. The heating tank can disperse the heat source and make the cardboard heat evenly heated. By heating from the top and bottom of the cardboard at the same time, the cardboard can be heated more evenly and the preheating efficiency can be improved. Attached Figure Description
