Description

Technical Field

[0001] The present application relates to the field of fire door processing, and in particular, to a limiting mechanism and a fire door processing device. Background Art

[0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. They are fireproof partitions with a certain degree of fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc. During the processing of fire doors, the fireproof panels need to be polished, and during the polishing process, a limit mechanism is required to limit and fix the fireproof panels. In the relevant limit mechanism technology, the structure used to clamp the fireproof panels is relatively simple, which can only clamp and fix the fireproof panels, and cannot drive the fireproof panels to rotate. This means that during the polishing process, when it is necessary to polish other surfaces of the panels, the fireproof panels need to be disassembled and re-clamped to adjust the position. When you want to fully polish the outer surface of the panels, you need to disassemble and clamp the fireproof panels multiple times, which is more troublesome and inconvenient.
