Cap feeding device capable of achieving real-time torsion control

The invention relates to a cap feeding device capable of achieving real-time torsion control. The cap feeding device comprises a rotating mechanism, a torsion control mechanism, a clamping mechanism and a propelling mechanism, wherein the rotating mechanism comprises a driving wheel, a driven wheel and a synchronous belt connected with the driving wheel and the driven wheel; the torsion control mechanism drives the driving wheel to rotate and controls real-time torsion; the clamping mechanism comprises a clamping jaw shaft connected with the driven wheel, a clamping jaw disc connected with the clamping jaw shaft and a telescopic clamping jaw used for clamping a bottle cap and connected to the clamping jaw disc; the propelling mechanism is used for driving the telescopic clamping jaw to clamp or open; and the propelling mechanism drives the telescopic clamping jaw to clamp a bottle cap to be screwed on a bottle body, the torsion control mechanism drives the driving wheel to rotate and controls real-time torsio
