A heating device for heating a powder attached to a substrate, including a housing, a heating member, a cover, a fan, and a filter. The housing is provided with a heating cavity. The heating member is accommodated in the heating member, and is configured to heat the powder attached to the substrate after conveyed to the heating cavity. The cover is mounted on the housing, and covers the heating cavity. The fan is mounted on the housing, and an air extraction pipe is arranged between the fan and the heating cavity to enable the fan to extract air from the heating cavity. The filter is provided in the air extraction pipe.

A vertical powder shaking and drying machine includes a frame, where the frame includes a feeding port provided on one side and a discharging port provided on the other side; a side of the frame close to the discharging port is externally provided with heating hoods; at least one heating hood is at an angle to a horizontal plane; the frame is internally provided with suction plates corresponding to the heating hoods; at least one suction plate is provided along a perpendicular direction; a purification and suction duct is provided above the suction plate; the purification and suction duct is located inside the frame; a side of the frame close to the feeding port is internally provided with a powder shaking box; and the powder shaking box is communicated with the feeding port and located at a front end of the suction plate.
