Spring looping machine for sliver can

The utility model relates to a cotton sliver can spring looping machine which comprises a machine base, a looping mechanism used for bending a metal wire into a spring is arranged on the machine base, and a stamping mechanism arranged on one side of the looping mechanism is further arranged on the machine base. The punching mechanism comprises a mounting base, the mounting base is connected with a rotating stand column and a swing angle movement device used for controlling the rotating stand column to axially swing relative to the looping mechanism, and the rotating stand column is connected with a punching forming device used for punching the spring in the circumferential direction when the spring is spirally shaped; according to the coiling machine, automatic production of springs is achieved, the automation degree is improved, manpower resource waste can be reduced, a plurality of break angles can be punched in the circumferential direction of the first circle of the sliver can spring through the punch for
