Description

Technical Field

[0001] The utility model relates to the technical field of extrusion wheels, in particular to an extrusion wheel adjusting device. Background Art

[0002] Extrusion wheels in a dry granulator mainly undertake the task of making powder or granular materials into granules through extrusion molding. Through rotation and extrusion, the materials are compressed into thin slices or strips, and then through subsequent processes such as crushing and sizing, finally forming qualified granular products. The surface of the extrusion wheel may be specially treated, such as processed into a reticulate pattern, straight pattern or smooth surface, etc., to match the production of materials with different characteristics. At the same time, the structural design of the extrusion wheel also focuses on the uniform distribution and efficient extrusion of materials. Generally, the distance between a pair of extrusion wheels needs to be adjusted in existing dry granulators. However, when adjusting the existing extrusion wheels, generally both extrusion wheels need to be driven by separate power mechanisms, and two separate power mechanisms are required for the two extrusion wheels, resulting in relatively large losses in a long-term working environment.
