Abstract
The invention provides an extrusion rod compressing apparatus for an extruder. The apparatus comprises an extrusion rod, an extrusion rod gland, an extrusion rod shaft pad and an elastic bolt structure, the extrusion rod gland is sleeved on the extrusion rod, and the tail end of the extrusion rod is fixed in the extrusion rod shaft pad; and the extrusion rod gland is fixed to the extrusion rod shaft pad through the elastic bolt structure. The extrusion rod compressing apparatus for the extruder guarantees proper compression of the fitting surfaces of the extrusion rod and the extrusion rod gland, and allows a certain gap to be residual between the close surfaces of the extrusion rod and the extrusion shaft pad, and a compressing device containing a disk spring group structure is adopted to compress the gap. The disk spring is elastic, so a certain deviation of the gap can be corrected through adjusting the elasticity of the disk spring; and the elastic coefficient of the disk spring is larger than that of common springs, so the compression force is reliable.
