[0023] A plurality of cleaning holes 9 are provided on the surface of the cutting table 2. The plurality of cleaning holes 9 are located on the side of the longitudinal cutting assembly 4 close to the blanking area. A blowing nozzle 10, an air duct 11, an air pump 12 and a brush 13 are provided on the machine body 1.
