Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of PVDF fluorine film production retracting device, packet
Pedestal 6 is included, 6 upper end of pedestal is equipped with the first fixed frame 2, and 6 upper end of pedestal is additionally provided with the second fixed frame 9, and pedestal 6 is equipped with installation
Frame, and idler wheel 7 is equipped in 6 mounting rack of pedestal, and 7 outer cover of idler wheel is equipped with two groups of conducting rings 14, the pedestal 6 of this structure is installed
The effect for erecting fixed idler whell 7 allows idler wheel 7 to touch retracting film, while the conducting ring 14 on idler wheel 7 can also contact
To retracting film, conducting ring 14 is distributed about idler wheel 7 center line bilateral symmetry, and the conductive plate of arc is fitted with outside conducting ring 14
8, and conductive plate 8 is mounted on pedestal 6, and the conductive plate 8 of this structure arc will not influence conducting ring 14 and be rotated, while can
To guide electrostatic on conducting ring 14, prevent on retracting film there are excessive electrostatic, it is logical that 2 two sides of the first fixed frame offer rectangle
Hole, and the first beaming roller 3 and the second beaming roller 13 are equipped in the first fixed frame 2, and spring 12 is equipped in 2 through-hole of the first fixed frame,
First fixed frame, 2 upper end offers threaded hole, and the first fixed frame 2 perforate in be equipped with threaded rod 1, the first fixed frame of this structure
Threaded hole on 2 plays the role of fixed thread bar 1, can be pressurizeed to the first beaming roller 3 by threaded rod 1, the first beaming roller 3
Spring 12 can be compressed, the rate of tension between the first beaming roller 3 and the second beaming roller 13 be controlled with this, 2 rectangle of the first fixed frame is logical
Hole two sides are equipped with set casing 5, and the set casing 5 of this structure can block the through-hole on the first fixed frame 2, prevent spring 12 from the
It is detached from the through-hole of one fixed frame 2,12 upper and lower side of spring is connected with pressing plate 4, and the original of spring 12 is long to be greater than in 4 rectangular through-hole of pressing plate
Minister's degree, the spring 12 of this structure can push up the first beaming roller 3 and the second beaming roller 13 towards two sides, control the first beaming roller 3 with this
