Plastic extruding machine with axial magnetic-suspension bearing

Abstract

The invention provides a plastic extruding machine with an axial magnetic-suspension bearing. On the extruding machine, a radial magnetic-suspension bearing of an extruding main shaft is used for replacing the traditional bearing, a thread rod is arranged at the middle part of the extruding main shaft, the rear part of the extruding main shaft is provided with the axial magnetic-suspension bearing, and the tail end of the extruding main shaft is provided with a mechanical bearing.

Description

Technical field [0001] The invention relates to an axial magnetic suspension bearing plastic extruder, in particular to an extruder in which the axial thrust of the main shaft of the extrusion structure replaces the mechanical bearing with the axial magnetic suspension force. It belongs to the technical field of plastic processing. Background technique [0002] In the field of plastic extrusion processing, the extrusion rods of traditional plastic extruders use mechanical thrust bearings. The damage to the mechanical thrust bearing is very serious, which will cause the entire product to be unusable, and the enterprise will stop production for a long time for maintenance and stop production for a long time. Contents of the invention [0003] On the extruder, radial magnetic suspension bearings are used to replace traditional bearings for the extrusion main shaft, with a threaded rod in the middle, an axial magnetic suspension bearing at the rear, and a mechanical bearing a...
