Capacitor sealing machine

The invention is applicable to the field of capacitor processing, and provides a capacitor sealing machine which comprises a machine base and a conveying belt, a plurality of fixing seats are arranged on the conveying belt, rotating pipes are fixed to the bottoms of the fixing seats and rotationally connected with the conveying belt, and gears are further fixed to the rotating pipes; the transmission assembly is fixed to the machine base and can be connected with the gear located in the sealing area in a meshed mode. A pneumatic assembly is mounted on the inner sides of the fixed seat and the rotating pipe, and is used for controlling the clamping plates to center the capacitor and then fixing the capacitor through the matching of the clamping plates and the negative pressure holes; the control assembly is fixed to the machine base and used for controlling the pneumatic assembly located in the sealing area to work. The girdling assembly is fixed to the machine base and used for extruding the outer wall of the
