US 12,179,947 B2 · Rebar bundling machine, replaceable gun head and working method thereof

Abstract

The invention discloses a rebar bundling machine, a replaceable gun head and a working method thereof. The replaceable gun head according to the present invention comprises a gun head information identification component provided on the gun head, wherein after mounting the gun head on the rebar bundling machine, the gun head information identification component is connected to a main control unit of the rebar bundling machine, and the main control unit obtains information of the gun head through the gun head information identification component. The rebar bundling machine of the present invention comprises a gun shell, a main control unit provided in the gun shell, and the replaceable gun head mounted on the front end of the gun shell; in the present invention, the number of rotations for the wire feeding motor and the torque threshold for the wire twisting motor are set for different muzzle information, so as to control the length and torque of the wire output from the rebar bundling machine with different gun heads; the invention can meet the applications of various sizes of rebars combined at construction sites, effectively reduce the burden of workers carrying and managing the rebar bundling machine, and greatly reduce the cost of machinery procurement at construction sites.
