Structure of homonymous parallel double-screw-rod extrusion machine

The invention discloses a structure of a homonymous parallel double-screw-rod extrusion machine. The structure comprises a base. A cylinder assembly is installed above the base and comprises an opening cylinder, a closing cylinder, a side feeding cylinder and an extruding cylinder. The cylinders are located through locating pins and connected through connecting bolts. The cylinder assembly is connected with a gear speed reduction box through a cylinder connecting body. The gear speed reduction box is installed above the base. An input shaft of the gear speed reduction box is connected with anoutput shaft of a motor through a coupling joint. Two screw rod assemblies are installed in the cylinder assembly. Replaceable thread sleeves and engagement blocks are installed on screw rod core shafts of the screw rod assemblies. The rear ends of the screw rod core shafts are connected with two output shafts of the gear speed reduction box through a spline sleeve assembly. The structure is convenient to assemble and dis
