This utility model relates to the technical field of TPU film production lines, specifically a tension adjustment device for a TPU film
production line, comprising: a tensioning
assembly, which includes a frame; and an adjustment
assembly, located on the top of one side of the frame, including a mounting frame, an electric push rod, a connecting plate, and a movable column. The mounting frame is fixed at both ends of one side of the upper surface of the frame, and two sets of mounting frames are provided. The electric push rod is fixed on the other side of the upper surface of any set of mounting frames, the connecting plate is fixed to the output end of the electric push rod, and the movable column is fixed to the upper surface of the connecting plate. It also includes a reinforcement
assembly located inside the mounting frame on one side. This utility model features a simple structure and reasonable design. The electric push rod provides rapid vertical adjustment capability, and the
ball screw-driven limit column achieves precise locking. The combination of these two features not only ensures micron-level precision in tension adjustment but also increases the device's effective speed by 50%.
