[0016] Beneficial effects of the present invention:

[0017] 1. The present invention sets two groups of placement brackets, and uses the two groups of placement brackets to fix the two ends of the paperboard. When the paperboard is fixed, it is only necessary to insert the two ends of the paperboard into the two placement brackets respectively, and use the positioning roller and the movable roller to fix the paperboard. The movable roller is movable. When squeezed, the slider moves up in the movable groove, and the spring column is squeezed at the same time, so that the end of the paperboard can be clamped between the movable roller and the positioning roller by the restoring force of the spring column, which plays a better fixing role. The movable roller is movable, so that the spacing between the movable roller and the positioning roller can be adjusted, which is suitable for fixing paperboards of different thicknesses. The movable roller and the positioning roller are used to fix the two ends of the paperboard, which effectively reduces the contact area with the surface of the paperboard, so that the surface coverage of the paperboard is low and the drying is more comprehensive.

[0018] 2. By setting up a guide frame, after one end of the cardboard enters between the movable roller and the positioning roller, as the cardboard continues to advance, its end first contacts the guide frame, and the guide block on the top of the support rod is used to guide the cardboard between the movable roller and the positioning roller on the inner side of the other bracket, which plays a precise guiding role, avoiding that the cardboard cannot accurately enter between the movable roller and the positioning roller located at the same height when fixed, facilitating the fixing operation of the cardboard, and at the same time using the guide frame to support the bottom of the cardboard, effectively reducing the situation where the upper and lower cardboards contact due to the bending of the middle of the cardboard.

[0019] 3. By setting up the adjustment structure, after the placement bracket is pushed, the connecting rod 1 and the connecting rod 2 move through the rotating shaft, and the rotating shaft connected to the end of the connecting rod 1 and the connecting rod 2 and the slide groove moves in the slide groove, so that the distance between the two connecting plates can be adjusted, and then the two placement brackets can be used for the placement of cardboards of different lengths, and the scope of application is wider.

[0020] 4. During the heating period, because the cardboard is fixed by movable rollers and positioning rollers, the exhaust fan uses side blowing to send air to the surface of the cardboard, so that the top and bottom surfaces of each cardboard can be covered, thereby making the drying efficiency of the drying equipment higher and the drying of the cardboard more comprehensive.

[0043] After the electric heating chamber 3 is powered on, the air inlet fan 2 starts to supply air to the drying box body 1. The air is filtered by the filter screen 26 and then enters the electric heating chamber 3. After being heated by the electric heating wire 27, it is sent to the drying box body 1 by the air inlet fan 2, so as to dry the upper and lower surfaces of the paperboard. During the drying period, the exhaust fan 4 is started regularly to exhaust air. The exhaust fan 4 exhausts the hot air in the drying box body 1 and sends it out after being filtered by the filter box 5.

[0044] After the drying operation is completed, the side panel 7 is opened, the cardboard is pulled out, and the drying operation is completed.
