Abstract
The utility model discloses a tension adjustment device for coiled materials. The tension adjustment device for the coiled materials comprises a machine frame and an adjustment rod arranged on the machine frame in a sliding mode, wherein a guide roller is further arranged between the adjustment rod and a coiling shaft, and a travel switch used for controlling the adjustment rod to stop suddenly is arranged in the position, corresponding to a sliding final end of the adjustment rod, of the machine frame. As the travel switch is arranged, once the tension of the coiled materials is large, whether the adjustment rod ascends or looses or descends, the adjustment rod will touch the travel switch, then sudden stop of the machine is achieved, the problems that the coiled materials are damaged or loose are avoided, the quality of products is improved, and production cost is lowered. The tension adjustment device for the coiled materials further comprises a control mechanism used for controlling the rotation speed of the coiling shaft, the machine frame is further provided with a detection mechanism used for detecting the position of the adjustment rod, and the detection mechanism is electrically connected with the control mechanism. The detection mechanism is arranged to detect the position of the adjustment rod in real time, once the adjustment rod is too high or too low, signals will be transmitted to the control mechanism, the control mechanism effectively adjusts the tensioning force on the surface of the coiled materials by adjusting the rotation of the coiling shaft, and work efficiency is improved.
