Outer diameter become larger, then the distance of outer surface to rotating shaft core of gap adjustment module 3 becomes larger；The outer diameter that gap adjusts module 3 becomes
Small, then the distance of outer surface to the rotating shaft core of gap adjustment module 3 becomes smaller；In this present embodiment, gap adjusts module 3 and turns
Axis 1 is coaxially disposed；
Roller 2 is sheathed on outside gap adjustment module 3, the different setting of axis of both roller and shaft, roller 2 it is outer
Around equipped with diaphragm 5, and diaphragm 5 supports roller 2 and is posted by outside gap adjustment module 3；
Pressure sensor 4 is set to 2 inside of roller and supports the region of roller 2 positioned at diaphragm 5, and the tension of diaphragm 5 is through roller
Cylinder 2 is transmitted on pressure sensor 4, and pressure sensor 4 knows pressure signal；
Gap adjustment module 3 is a kind of tension element, is electrically connected with pressure sensor 4, and pressure sensor 4 is by pressure
Signal transmission to gap adjusts module 3, and gap adjusts module 3 and adjusts outer diameter according to pressure signal, to change the volume of diaphragm 5
Diameter, adjustment 5 tension of diaphragm.
When the outer diameter that gap adjusts module 3 becomes larger, the distance of outer surface to the rotating shaft core of gap adjustment module 3 becomes larger,
Minimum range between diaphragm 5 and rotating shaft core becomes larger, and the coil diameter of diaphragm 5 becomes smaller, and suffered tension becomes larger on diaphragm 5；Similarly,
When the outer diameter that gap adjusts module 3 becomes smaller, the distance of outer surface to rotating shaft core of gap adjustment module 3 becomes smaller, diaphragm 5 with turn
Minimum range between axis axle center becomes smaller, and the coil diameter of diaphragm 5 becomes larger, and suffered tension becomes smaller on diaphragm 5.Therefore, it is passed in pressure
Obtained on sensor 4 pressure signal be less than preset value when, then show that the tension suffered by diaphragm 5 is too small, need to by gap adjust module 3
