Glue recycling device of packaging machine

The invention discloses a glue recycling and reusing device of a packaging machine. The glue recycling and reusing device comprises a telescopic mechanism, a rotating mechanism and a push type stirring head. The telescopic mechanism comprises a vertical plane supporting plate, a servo motor is fixed to the plane supporting plate, the output end of the servo motor is connected with a ball screw through a coupler, and the ball screw is sleeved with a workbench in threaded connection. A limiting mechanism for limiting rotation of the workbench is further arranged on the plane supporting plate so that the ball screw can drive the workbench to ascend or descend. The rotating mechanism comprises a pneumatic motor, the pneumatic motor is fixed to one side of the workbench, the output end of the pneumatic motor is connected with a push type stirring head, and the push type stirring head extends into the glue barrel. Under the combined action of the servo motor and the pneumatic motor, the glue solution is stirred thr
