Detailed Description
The following further describes embodiments of the present invention in conjunction with the drawings of the specification. The embodiments described below are exemplary and are intended to be illustrative of the utility model, but are not to be construed as limiting the utility model.
As shown in fig. 1-4, an electric cutting tube structure of a binding machine comprises: the pipe cutting machine comprises a workbench 5, a power device 1 arranged on the workbench 5 and a pipe cutting knife 4 connected with the power device 1; the pipe cutting machine is characterized in that an eccentric wheel 2 is connected to the power device 1, a push rod 3 capable of moving back and forth is mounted on a workbench 5, and the push rod 3 is movably connected with the eccentric wheel 2 and fixed with the pipe cutting knife 4.
The electric cutting tube structure of the binding machine provided by the embodiment has the working process and the principle as follows: the power device drives the eccentric wheel 2 to rotate, and due to the movable connection between the push rod 3 and the eccentric wheel 2, the rotating motion of the eccentric wheel 2 can be converted into the reciprocating motion of the push rod 3, so as to drive the pipe cutter 4 fixed with the push rod 3 to reciprocate, and realize the cutting off and resetting of the rubber pipe in the pipe conveying channel. The duct conveying channel and the duct conveying frame corresponding to the duct conveying channel are common technical knowledge grasped by those skilled in the art, and are not described and illustrated herein.
