Linkage operation device for punched aluminum cover surface convex identifier

The invention discloses a linkage operation device for a punched aluminum cover surface convex identifier. A cam mechanism and a cone pulley mechanism are arranged at the top of the device, a supporting part is arranged at the bottom of the device, and a cam is sleeved on a cam shaft and can rotate around the cam shaft; a cone pulley is horizontally arranged at one end of the cam shaft, the othercone pulley is vertically arranged at the upper end of a cone pulley shaft, and the two cone pulleys are mutually engaged; the lower end of the cone pulley shaft is connected with an eccentric wheel,the eccentric wheel is transversely and movably connected with one end of a connecting rod, the other end of the connecting rod is connected with one end of a swinging rod, and the other end of the swinging rod is connected with a ratchet pawl; and the bottom of a main shaft is vertically connected with a bracket, a ratchet corresponding to the ratchet pawl is fixedly arranged in the middle of the main shaft, the top of the main shaft is movably connected with a main turntable, and a plurality of positioning round pins for positioning an aluminum bottle cap are uniformly and fixedly arranged on the periphery of the upper surface of the main turntable at intervals. When the cam rotates for one circle for one-time punching, the main turntable rotates for one grid; and the turntable realizeslinkage operation, so the punching time is saved, and the production efficiency is improved.
