Wherein the pressing plate mechanism 31 is adapted to perform a first action to press a first portion of the material. The folding mechanism 32 is configured to drive the second portion of the material to move toward the end of the first portion after the pressing mechanism 31 presses the first portion of the material until the end of the second portion of the material overlaps the end of the first portion.

More specifically, the platen mechanism 31 includes a material platen 311 and a first driving member 312. The first driving component 312 is connected to the material pressing plate 311, and is used for driving the material pressing plate 311 to perform the first action, and is also used for driving the material pressing plate 311 to perform the second action to release the pressed material.
