Embodiment

After constitution content of the present utility model and other characteristics can describe in detail at the embodiment of the following conjunction with figs. of reading, and be tending towards clear.

Shown in Fig. 1～Fig. 3 A, Fig. 3 B, a kind of winding pressure adjusting mechanism of the utility model, it comprises:

One winding mechanism 1 has two groups of charging guide wheels, 11,12, one contact wheels 13, a pressure detection mechanism 14 at least, and a mobile platform 15; Described

charging guide wheel

11,12, and contact wheel 13, pressure detection mechanism 14 are installed in respectively on the mobile platform 15.Described pressure detection mechanism 14 further comprises: a top wheel arm 141, a pneumatic cylinder 142, a sensing chip 143 and a transducer 144 (being pressure sensor); Described mobile platform 15, mainly include a track underframe 150, pneumatic cylinder 151 and movable plate 152, described track underframe 150 is provided with described pneumatic cylinder 151, then set firmly described movable plate 152 on the pneumatic cylinder 151, and further be provided with a movable block 153 on the movable plate 152, it is spacing with dead axle 155 serial connections to offer arc guide channel 154 in the middle of the described movable block 153, being provided with pivot 156 under the described movable block 153 makes movable block 153 be positioned a solid motion block 157, and make movable block 153 can local swing be connected with edge at movable plate 152, and be respectively equipped with relative transducer 144 and sensing chip 143 on solid motion block 157 and the movable block 153, and movable block 153 tops are for setting up contact wheel 13, the then prominent top wheel arm 141 of establishing in movable block 153 inboards, this top wheel arm 141 is oppositely arranged with the piston rod of pneumatic cylinder 142; And,
