Pressurized masticator capable of reducing residual plastic of raw materials

The utility model relates to the technical field of masticators, in particular to a pressurized masticator capable of reducing residual plastic of raw materials. According to the technical scheme, the device comprises a machining box, a cleaning assembly and a transmission assembly, the cleaning assembly is installed on one side of the machining box, a lead screw is installed in an auxiliary box, a screw sleeve is installed on the outer side of the lead screw, a cleaning arc plate is installed on one side of the screw sleeve, and the transmission assembly is installed at the bottom of one side of the machining box; and a transmission gear is mounted at the top of one side in the transmission box. Residual raw materials adhered to the inner wall of the processing box can be scraped off through the cleaning arc plate, increase of follow-up cleaning burden caused by too long adhesion time of the raw materials is avoided, meanwhile, the blockage phenomenon caused by follow-up processing after adhesion of the raw
