Device for integrally elevating extruder

A device for integrally elevating an extruder is mainly composed of the following components: four screw elevators, two spiral bevel gear steering machines, a motor direct-connected worm gear reducer, quincunx resilient couplings, transmission shafts, four elevator bases, two steering machine bases and a reducer base. The reducer base and the steering machine bases are fixed with a rear end of a matched extruder underframe. The elevator bases are symmetrically welded at two sides of the extruder underframe. The motor direct-connected worm gear reducer, the steering machines and the elevators are respectively provided on the bases which respectively correspond with the motor direct-connected worm gear reducer, the steering machines and the elevators, and are connected in series through the transmission shafts and couplings. The elevating device of the utility model is directly provided on the base of the extruder. When product change is required, the adjustment of the integral height of the extruder is require
