Packing strap length cutting device

Abstract

A strapping tape length cutting device includes a mobile carrier and a control box. The mobile carrier has a housing unit configured to carry a strapping tape. The control box has a tape inlet and a tape outlet. A guide unit, a feeding unit, and a cutting unit are sequentially arranged inside the control box, collectively defining a conveying path. The feeding unit includes a base, a vertical plate, a motor base, and a feeding motor. The vertical plate has a tape threading hole, and the output end of the feeding motor is drivenly connected to a pressure roller. The cutting unit is located adjacent to the tape outlet. The cutting unit includes a cutting motor, a transmission component, and a cutting component. The transmission component is connected between the cutting motor and the cutting component. Thus, the strapping tape is fed along the conveying path to the cutting unit through the feeding unit, and the feeding and cutting actions are performed according to the set cutting length and quantity, thereby completing the strapping tape length cutting operation.
