Abstract

A capping machine, comprising a depressing member, a cap pressing device connected to the depressing member, a supporting device, a transmission device, a first driving wheel, a second driving wheel, and an actuating wheel, wherein the first driving wheel is rotatably connected to the depressing member, wherein the depressing member comprises a driver member, while the cap pressing device comprises a driver ring, wherein the driver member is received in the driver ring, wherein the depressing member is engaged with the first driving wheel such that the first driving wheel is arranged to drive the depressing member and the cap pressing device in a vertical direction, wherein the depressing member is driven to rotate by the transmission device, while the supporting device is also rotatably connected to the transmission device so as to rotate with the depressing member in a synchronized manner.

1 . A capping machine, comprising a depressing member, a cap pressing device connected to said depressing member, a supporting device, a transmission device, a first driving wheel, a second driving wheel, and an actuating wheel, wherein said first driving wheel is rotatably connected to said depressing member, wherein said depressing member comprises a driver member, while said cap pressing device comprises a driver ring, wherein said driver member is received in said driver ring, wherein said depressing member is engaged with said first driving wheel such that said first driving wheel is arranged to drive said depressing member and said cap pressing device in a vertical direction, wherein said depressing member is driven to rotate by said transmission device, while said supporting device is also rotatably connected to said transmission device so as to rotate with said depressing member in a synchronized manner. 
     
     
         2 . The capping machine, as recited in  claim 1 , further comprising an auxiliary ring movably mounted on said cap pressing device, a gear assembly mounted on said cap pressing device at a position underneath said auxiliary ring, and a resilient element mounted between said auxiliary ring and said gear assembly for normally exerting an upward force to said cap pressing device.
