The invention discloses a foamed plastic
cutting machine. The structure of the foamed plastic
cutting machine comprises power shafts, a bracket, a transmission rod, a
machine body, adjusting seats, anegative pressure plate, an electrothermal wire
pipe and a
self cleaning cutter, wherein the power shafts are arranged at two ends of the bracket, and are mutually connected with each other through the transmission rod. The foamed plastic
cutting machine disclosed by the invention has the beneficial effects that a planning wheel seat is driven by the
self cleaning cutter relying on the power provided by a conducting shaft and a power
pipe to vertically extend downwards from a position at the topmost end of the electrothermal wire
pipe to be mutually adhered to the electrothermal wire pipe, atthe same time, through the rotating acting force of the planning wheel seat, cleaning tooth blocks are embedded with the electrothermal wire pipe, and in the sliding downwards and rolling process, plastic defective materials produced on and adhered to the electrothermal wire pipe are planned and scraped; and after the plastic defective materials are scraped, the planning wheel seat can be voluntarily reset relying on a spring rod of the power pipe, so that the situation that subsequent operations are influenced is avoided.
