Cutting device for foam tape

The invention relates to a foam adhesive tape cutting device which comprises a rack, a mounting frame is slidably mounted on the rack, a knife rest is arranged on the mounting frame, a cutting knife is rotatably mounted on the knife rest, a first driving mechanism used for driving the cutting knife is arranged on the knife rest, and the knife rest is used for driving the cutting knife to move to cut foam adhesive tape. The cutting knife performs inclined feeding and vertical cutting, a second driving mechanism is arranged on the rack and used for driving the mounting frame to move, and a third driving mechanism is arranged on the mounting frame and used for driving the knife rest to move. The cutting device has the beneficial effects that due to the fact that the cutting knife is obliquely fed during cutting feeding, the pushing force of the cutting knife during cutting feeding is divided into the abutting force perpendicular to the axis of the foam rubber and the pushing force parallel to the axis of the foa
