Description

Technical Field

[0001] The utility model relates to a sanding machine grinding device, belonging to the technical field of metallurgical equipment. Background Art

[0002] The rod polishing process is to grind the surface defects (including pits or processing residues) of the rod with polishing equipment to obtain a finished rod with high surface quality. Currently, there are two main methods: manual polishing and mechanical polishing. Manual polishing is gradually replaced by mechanical polishing due to its low efficiency and polishing accuracy. Mechanical polishing mainly uses a sanding machine, which drives the annular sanding belt to rotate through the motor on the base, and continuously polishes the surface of the rod with the sanding belt, which has high polishing integrity and polishing accuracy.

[0003] Currently available sanding machines do not have a belt break detection function. If a belt break occurs during the polishing process of a bar, an alarm cannot be issued in time, which affects product quality and is likely to cause damage to the equipment, or even a safety accident.
