[0002] The cage-type stranding machine is a special equipment for stranding control cables, rubber cables, steel stranded wires, steel-core aluminum stranded wires, copper stranded wires, aluminum stranded wires and soft stranded wires produced by power line and cable factories. The cage-type stranding machine will rotate during operation, and there will be a certain tension in the wires. When the wires break, it can easily cause danger.

[0003] After searching, the utility model patent with announcement number CN219476390U discloses a cage-type stranding machine with a safety protection mechanism, including a mounting frame and a pay-off frame, a driving rod is arranged on the mounting frame and near the center, a pay-off mechanism distributed in a ring array is arranged on the pay-off frame, a guide disk is arranged on the driving rod and located on the right side of the pay-off frame, a guiding mechanism is arranged on the guide disk, a protective frame is arranged on the right side of the guide disk, and a limiting mechanism is arranged on the inner side of the protective frame; this patent provides an outer frame and a protective frame, and the equipment on the inner side of the outer frame is provided with overall protection to improve the safety during stranding, the protective frame can provide protection on the outside of the wire, and the limiting ring and the guide wheel cooperate with each other to guide and limit the wire for multiple times, so that the wire is gradually gathered to the right, thereby improving the stability of the wire, preventing friction and collision between the wires, and avoiding damage to the surface of the wire to affect the quality of the stranded wire.

[0004] However, the above patents still have the following shortcomings: the aperture on the outer frame is large, which cannot provide good protection when the wire breaks during stranding, and it is not convenient to load and unload materials on the stranding machine after the outer frame is installed. At the same time, the stranding machine will generate noise during operation, affecting the surrounding environment. For this reason, we propose a safety protection mechanism for a cage-type stranding machine. Utility Model Content
