The invention discloses a non-
woven fabric cutting device capable of achieving different
cutting sizes. The non-
woven fabric cutting device comprises a fixing frame, wherein a material roller support and an n-shaped support are fixedly connected to the upper surface of the fixing frame, a through hole is formed in the front face of the material roller support, a rotating shaft is rotatably connected to the inner wall of the through hole, a
servo motor is fixedly connected to the back face of the fixing frame, a main rotating roller is fixedly connected to the output end of the
servo motor, and fixing plates are fixedly connected to the upper surface and the lower surface of the fixing frame. The non-
woven fabric cutting device is reasonable in structure; through arrangement of a belt
pulley, a conveying belt, an n-shaped guide rail, a gear motor, a gear, a guide plate, a step column and pressing plates, the gear motor can be started conveniently, and thus the belt
pulley and the non-woven fabric move synchronously; and under the action of the inclined guide plate, the step column is extruded, and the pressing plates on the two sides of a cutting blade press non-woven fabric tightly, and meanwhile, the non-woven fabric is
cut by the cutting blade, so that pause is not needed, and the production efficiency is effectively improved.
