[0030] During the use of the pulp mold coating infrared drying device, the pulp mold 3 is moved by the conveyor belt 2, and the position of the movable limit component 4 is automatically adjusted by the limit component 4, which plays an auxiliary anti-falling effect, allowing the pulp mold 3 to enter the interior of the oven 5.

When the pulp molding 3 contacts the auxiliary plate 43, it will rotate along the movable shaft 48 through the auxiliary roller 47 to smoothly transport the pulp molding 3.
