Description

X discloses a full-automatic waist rope winding and sealing head machine, which comprises a rack, an electric control box mounted on the rack, a rope feeding mechanism and a rope winding mechanism. The rope feeding mechanism feeds the waist rope to be processed to the rope winding mechanism for winding processing. The rope feeding mechanism comprises a length measuring device, a cutting device and a pushing device. The rope winding mechanism comprises a knotting machine and a winding belt feeder. The full-automatic waist rope winding and sealing head machine disclosed in the patent automatically feeds the waist rope to be processed to the winding clamp of the winding belt feeder.
