Seat belt webbing closed loop tension corrector

Abstract

This utility model relates to the field of seat belt production, and more particularly to a closed-loop tension corrector for seat belt weaving. It includes a bracket, a first mounting frame, a second mounting frame, a second roller, a second motor, and a torque sensor. A first hydraulic cylinder is embedded inside the bracket. The first mounting frame is located on one side of the first hydraulic cylinder. A lifting frame is inserted into the upper end of the first mounting frame, and a limiting plate is located at the lower end of the lifting frame. The second mounting frame is located on one side of the lifting frame, and the second roller is arranged in a linear array at its lower end. The second motor is located on one side of the second mounting frame, and a torque sensor is located on the outer wall of the machine body where the rotating shaft of the second motor extends. This device has real-time tension detection, dynamic adjustment, and early warning functions, solving the problem of uneven local tension caused by sewing, winding, or yarn fluctuations during the existing seat belt weaving process.
