Description

Technical Field

[0001] The utility model relates to the technical field of tension control equipment, in particular to a tension control equipment for paper conveying. Background Art

[0002] Laminated silicone-coated release paper is a type of laminated paper. In order to ensure the flatness of the paper during transportation, the tension of the laminated paper needs to be controlled and adjusted.

The lifting rod is provided with a lifting mechanism, and the lifting mechanism is fixedly installed in the driving box. The output end of the lifting motor extends to the support seat and is fixedly installed on the right end of the driving wheel. The top of the lifting rod extends out of the support seat and is fixedly installed on the mounting frame. A second conveying mechanism is provided on the right side of the support seat. Since the thread on the lifting rod cooperates with the thread on the driving wheel, the lifting rod rises, and the limiting wheel rotates at the same time to maintain the stability of the lifting rod. The lifting rod drives the mounting frame to rise, and the mounting frame drives the tension wheel to rise, so that the top of the tension wheel is against the paper, thereby completing the adjustment of the paper tension. The device is easy to use, and the paper tension can be adjusted by driving the tension wheel to rise and fall by the lifting motor.

[0004] The above-mentioned tension control device adjusts the tension of the paper through the provided lifting structure, but the degree to which a single lifting structure can adjust the tension of the paper is limited, resulting in a problem of a small tension adjustment range during paper transportation. Therefore, we provide a tension control device for paper transportation. Utility Model Content
