Description

Technical Field

[0001] The utility model relates to the technical field of guide rollers, in particular to a thermal expansion type aluminum guide roller. Background Art

[0002] The working principle of the thermal expansion aluminum guide roller is based on electromagnetic induction heating. Its internal coil generates an electromagnetic field, which generates Joule heat by cutting the metal surface through magnetic lines of force, causing the roller itself to heat up. The roller surface then exchanges heat with the material being processed, and the set working temperature of the roller is maintained through a closed-loop temperature control system. The guide roller has the characteristics of high hardness, light weight, good thermal conductivity, and strong operating stability. It is widely used in the deep processing of various polymer materials, such as PVC sheet processing, chemical fiber spinning processing, composite material processing and other fields.
