The invention discloses a dividing and
cutting machine with a straight knife dividing and
cutting mechanism and a using method of the dividing and
cutting machine. The dividing and cutting
machine comprises a power distribution cabinet, fifteen knife bases and two symmetrical triangular plates, wherein a controller is installed on the inner side wall of the power distribution cabinet, the rear surface of the power distribution cabinet is in threaded connection with a slide
carriage box through screws, one side of the slide
carriage box is fixedly connected to a
material storage roller through a coupler, one side of the slide
carriage box is fixedly connected to two connecting rollers through couplers, a straight knife module is designed on the basis of a jaw structure of the knife bases and can be rapidly assembled and disassembled, the jaw structure and a cross beam strip can be accurately buckled, a guide rail groove can be moved in a double-point matching mode through a protruding block in a moving process, the mechanical characteristic of stepped adjustment of a pawl and a
ratchet bar is utilized in the moving process, the cutter bases form reverse
stroke stepped feeding motion, so that the cutter bases are accurately positioned at each scale of a scale plate in the moving process, and the requirements of accurate moving and positioning are met.
