Cutting device of acrylic plate bar for plastic manufacturing

The utility model discloses a cutting device of an acrylic plate bar for plastic manufacturing, which comprises an extrusion device, a support frame is arranged at the top of the left side of the extrusion device, an air cylinder is fixedly connected to the top of the support frame, and the output end of the air cylinder penetrates into the support frame and is fixedly provided with a cutter body. According to the utility model, the cutter body is driven by the air cylinder to downwards cut an acrylic plate bar and then upwards reset, then the transmission mechanism drives the scraping plate to reciprocate back and forth through the reciprocating lead screw and the screw sleeve, so that the scraping plate scrapes waste on the surface of the cutter body, and finally, the fallen waste is collected by the material receiving mechanism. The cutting-off device has the advantage that the cutter is convenient to clean, the problems that an existing cutting-off device is not internally provided with a certain scraping
