The invention discloses a separated type plastic extruding machine convenient to use. The separated type plastic extruding machine comprises an outer frame; a first motor is fixedly connected to the left side of the outer frame; one end of an output shaft of the first motor penetrates through the outer frame and extends into the interior of the outer frame; a stirring rod is fixedly connected to the end, located in the outer frame, of the first motor; a second motor is fixedly connected to the bottom of the outer frame; and one end of an output shaft of the second motor penetrates through theouter frame and extends into the interior of the outer frame. The invention relates to the technical field of plastic extruding machines. According to the separated type plastic extruding machine convenient to use, the purpose of increasing the heating and melting rate can be achieved, the working efficiency can be improved, the waste of time can be reduced, people can use the machine conveniently, meanwhile, energy can be saved, melted raw materials can be conveniently extruded, the extrusion quality can be improved, processing can be guaranteed, the raw materials can be convenient to enter,intermittent feeding can be realized, melting can be facilitated, plastic extruding can be facilitated, meanwhile, the stability of a device can be improved, and the service life of the device can beprolonged.
