Wrapper cutter

A wrapper cutter, comprising:

• a shell having an axially penetrating hollow structure;
• an elongated slit extending from a first end of the shell along an axial direction of the shell, and the elongated slit formed between a first side edge and a second side edge of the shell;
• a cutting knife fixedly arranged within the elongated slit, wherein a blade of the cutting knife faces the first end of the shell, and the cutting knife is configured to cut a section of paper passing through the elongated slit;
• a vertical plate arranged on an outer wall of the shell, the vertical plate having a first surface facing the axially penetrating hollow structure and an opposing second surface facing away from the axially penetrating hollow structure, a height of the vertical plate extending along a circumferential direction of the shell, an upper edge of the vertical plate extending from an inner end of the second side edge of the shell, and the vertical plate at least partially covering the elongated slit to allow a gap formed between the vertical plate and the elongated slit for the section of paper to pass through;
• and
• a fixed plate arranged on the second side edge of the shell and facing the first surface of the vertical plate;
• wherein the fixed plate narrows a width of the elongated slit and prompts the section of paper introduced into the elongated slit to approach the first side edge in a process of approaching the cutting knife.
