The surface of the inclined area (02) corresponding to the stripping device (2) and the surface of the plane area (01) are at the same height, so that the printing model (3) in the plane area (01) is not disturbed. If the surface of the inclined area (02) is higher than the surface of the plane area (01), the model (3) is separated from the conveyor belt (11) on the plane area (01) and the model (3) is inclined to a certain degree, so that the cross section of the printing model (3) at the position of the nozzle is changed in direction, and the printing effect is influenced.
Specifically, a ratio alpha of a distance L1 between the axis of the stripping device (2) and the axis of the first conveying direction side roller (13) to a distance L2 between the axis of the stripping device (2) and one conveying direction edge of the hot bed (14) is 5-6.

Or the rotating direction of the special-shaped rotating shaft (21) can be the same as that of the driving roller, in a more preferable scheme, the linear speed of the top end of the strip-shaped protrusion (20) abutted to the conveying belt (11) is the same as that of the conveying belt (11), and further when the strip-shaped protrusion abuts against the conveying belt (11), resistance cannot be generated on rolling of the conveying belt (11).
