The invention relates to the technical fields of wallpaper processing, in particular to a wallpaper processing and drying device. The wallpaper processing and drying device comprises a shell; the shell is divided into a plurality of drying chambers from top to bottom, and thermometers are correspondingly arranged in the drying chambers; the uppermost drying chamber is externally connected with a hot air blower; rollers are arranged inside the drying chambers; partition boards are arranged between the drying chambers; each partition board is divided into a left part and a right part which are rotationally connected with the left wall and the right wall of the shell correspondingly, rolling shafts are also arranged on the opposite ends of the partition boards, adjusting rods are arranged on the partition boards, threads are arranged on the adjusting rods, the adjusting rods extend out of the shell and are provided with locking nuts; and observation mirrors are arranged corresponding to the partition boards on the shell. The wallpaper processing and drying device adopts upper-lower interlayer design, and thermal diffusion is used for achieving wallpaper drying at different temperatures and occupation of the transverse space is reduced; and the partition boards are adjustable, and the stress on wallpaper is easy to change, the device can adapt to deformation is generated when the wallpaper is dried, and the smoothness of the wallpaper is guaranteed in the drying process.
