The utility model discloses an electric belt tightening
machine which comprises a shell, a
cut-off mechanism, a tightening mechanism and a speed
control switch, the
cut-off mechanism, the tightening mechanism and the speed
control switch are installed on the shell, the
cut-off mechanism comprises a cut-off tool apron, a cut-off tool and a cut-off tool bar, and the tightening mechanism comprises a tightening motor and a rotating shaft; the speed regulation switch is connected with the controller, the rotating speed of the tightening motor is controlled through the speed regulation switch, after binding is conducted through a binding belt, the
tail of the binding belt firstly penetrates into the binding belt channel in the front of the
cutting tool apron, penetrates through the
cutting opening and then penetrates out of the binding belt channel in the rear to enter the rotating shaft, and the tightening motor controls the rotating shaft to rotate to pull the binding belt to penetrate through the
cutting tool apron and tighten the binding belt. The cut-off tool is driven to rotate by rotating the cut-off tool bar, and the cut-off tool cuts off the
tail of the ribbon in the cut-off opening. According to the utility model, the cable tie can be intelligently tightened, meanwhile, the shearing operation is quickly performed, the
machine has multiple purposes, the
operation time is shortened, and the working efficiency is improved.
