Description

Technical Field

[0001] The utility model relates to a guide spacer ring device for a roller conveyor after bar shearing, and belongs to the technical field of roller conveyors after shearing. Background Art

[0002] After initial cooling on a cooling bed, rebar is fed to a cold shear for cutting to length. After shearing, it is conveyed via a post-shear roller conveyor to a secondary cooling bed for the next process. Due to the length of the post-shear roller conveyor, the finished product is typically over 9 meters long. Furthermore, the roller surface is relatively wide, typically reaching 1000mm. This creates a demanding guide requirement for the post-shear roller conveyor during conveying. This guide condition causes severe wear and jamming on the roller floor, impacting the accuracy of subsequent processes. This problem plagued the workshop, and a solution remained elusive.
