The invention provides an improved pay-off gravity type breaking protection device of a stranding machine. The improved pay-off gravity type breaking protection device of the stranding machine comprises a face machine pay-off table and an L-shaped support fixed to the face machine pay-off table, wherein a breaking protection copper sheet fixing plate is fixed on a flat plate at the bottom end of the L-shaped support, insulated nylon fixing pins are arranged at two ends of the breaking protection copper sheet fixing plate, and a breaking protection copper sheet is arranged on the breaking protection copper sheet fixing plate through the nylon fixing pins; a limiting transverse plate is fixed on a side wall plate of the L-shaped support, a plurality of limiting grooves are formed in the limiting transverse plate, a vertical plate is inserted into each limiting groove, a bearing and a bearing bush are arranged on each vertical plate, and each bearing bush is directly arranged on single wires during working. According to the improved pay-off gravity type breaking protection device of the stranding machine, the single wires run under the bearing bushes on the vertical plates, once the wires are broken, the vertical plates can immediately drop along a rectangular groove of the limiting transverse plate, touches the breaking protection copper sheet and gives an alarm, the device can adapt to detection of wire breakage and less wires of steel wire ropes in various specifications, the accuracy is high, the product percent of pass is increased, and the production cost is reduced.
