What is the internal structure of the automatic core winding machine---Fujian core winding machine

The paper strip tension adjustment mechanism of the automatic core winding machine is one of many kinds of machinery for household paper processing. The automatic core winding machine is designed to make the adjustment more convenient and accurate. It contains a paper scroll and has the following structure: a fixed shaft with an external thread on its outer end, and a strip key protruding from the shaft surface near the inner end of the external thread. The strip key is parallel to the axis and is fixedly mounted on the shaft. Frame; a rotating shaft with a transparent circular hole in the center, and the shape of the circular hole at the outer end of the shaft is a tapered hole; the transparent circular hole of the rotating shaft is in dynamic fit with the part before the strip key of the fixed shaft ; A tapered plug adapted to the shape of the tapered hole, its central part has a through hole matching the cross-sectional shape of the strip key part of the fixed shaft, and it is sleeved on the strip key part of the fixed shaft, and the fixed shaft The shaft is dynamically matched; a spring is sleeved on the fixed shaft and is compressed and installed between the rotating shaft and the tapered plug; an adjusting nut, the internal thread of which is dynamically matched with the external thread of the outer end of the fixed shaft, its inner The end face is pressed against the outer end face of the tapered plug. ---Fujian Core Rolling Machine
