The interior of the two blowing boxes 4 Each of them is equipped with multiple heating rods 6, an L-shaped box 7 is placed on the rear side of the blowing box 4, a vent 8 is provided on the L-shaped box 7, a filter 9 is installed inside the vent 8, a ventilation box 10 connected with the vent 8 is installed on the L-shaped box 7, a fan 11 is installed on the ventilation box 10, the fan 11 is connected with the two blowing boxes 4 through a ventilation hose 12, an air inlet 13 is provided at the side end of the L-shaped box 7 corresponding to the filter 9, the side end of the lower seat 2 is fixedly connected to two L-shaped seats 17, and the middle of the two L-shaped seats 17 is rotatably connected to two guide rollers 18, which play a guiding role for the white cardboard.

[0031] Specifically, the waterproof membrane material is coated on the white cardboard through the coating machine body 1, and the white cardboard coated with the waterproof membrane material is transported to the middle of the upper seat 3 and the lower seat 2. At the same time, the fan 11 blows air into the two blowing boxes 4, and the multiple heating rods 6 inside the two blowing boxes 4 heat the internal air. The heated air is evenly blown onto the white cardboard through multiple blowing ports 5 to dry the waterproof membrane material on the white cardboard, so that the waterproof membrane material on the white cardboard can be quickly solidified to form a waterproof membrane, which is convenient for people to collect the white cardboard coated with the waterproof membrane, thereby improving its practicality. The upper seat 3 is pulled to rotate by two electric cylinders 15, so that the upper seat 3 is rotated to one side of the lower seat 2, so that the white cardboard can be passed through the middle of the upper seat 3 and the lower seat 2.

[0032] See also Figure 3 and Figure 4 A box cover 19 is installed at the top of the L-shaped box 7, and a water spray pipe 20 is connected to the bottom end of the box cover 19. A plurality of nozzles 21 are installed on the water spray pipe 20. A water supply pipe 22 is connected to the box cover 19.
