Automatic sheet overlapping mechanism for sheet packaging machine

The utility model discloses an automatic sheet overlapping mechanism for a sheet packaging machine, comprising turntable mounted on a bracket. The plane of the turntable is vertical to the horizontal plane; a static chain wheel rotating synchronously with the turntable is arranged at the middle of the plane of the turntable; a plurality of synchronous chain wheels are uniformly connected with the external circle of the plane of the turntable taking the static chain wheel as the centre in a rotary mode; the static chain wheel has the same teeth as the synchronous chain wheel; the synchronous chain wheels are connected with a supporting device which is used for supporting a pole plate; the synchronous chain wheels and the static chain wheel are driven by chains; a conveying device for placing the pole plate on the supporting device is arranged at the left side of the turntable; and a discharging device for receiving the pole plate from the supporting device is mounted at the right side of the turntable. In the automatic sheet overlapping mechanism for the sheet packaging machine, the turntable is arranged, the static chain wheel is arranged on the turntable shaft, and the chain system consisting of the synchronous chain wheels and the chains is arranged on the plane of the turntable, the pole plate on the supporting device connected with the synchronous chain wheels is ensured to be in level state, thus the input pole plates can be levelly overlapped sequentially. The automatic sheet overlapping mechanism for sheet packaging machine has simple structure and high sheet overlapping efficiency and is reliable to operate.
