Cam linkage device and bottle body capping production line

The invention belongs to the technical field of linkage devices, and particularly relates to a cam linkage device and a bottle body capping production line. The cam linkage device comprises a linkage motor; a cam cap feeding mechanism is used for capping a bottle body; a cam cap screwing mechanism is used for screwing a bottle cap; a transmission mechanism is connected with the cam cap feeding mechanism to drive the cam cap feeding mechanism to lift and swing; the transmission mechanism is connected with the cam cap screwing mechanism to drive the cam cap screwing mechanism to lift; and a cam divider is driven by the linkage motor to enable the transmission mechanism and a bottle carrying rotary disc assembly to act, and the cam cap feeding mechanism and the cam cap screwing mechanism are in synchronous linkage with the bottle carrying rotary disc assembly. According to the cam linkage device and the bottle body capping production line, the cam divider is matched with the linkage motor and the transmission me
