Thin film, under the comprehensive function of self gravitation and film support power, is played tensioning by roller 19
Effect.More particularly, the most fixing between lower wall and the bearing block 20 of mounting groove 4a
Spring 21, one end of spring 21 is had to be fixed on the bottom surface of mounting groove 4a, spring 21
The other end be fixed on the bearing block 20 of idler roller 19 end, in the effect of spring 21
Just can extenuate the pressure that idler roller 19 presses on thin film down, make to act on thin film
Moderate pressure, the motion to idler roller 19 simultaneously also has the effect of buffering.
The operation principle of the wrap-up of this BOPP thin film is such that
1, the processed thin film completed from stretching-machine out, on entrance support three to be cooled
Strainer, the thin film right live-roller 18 from support three top conveying come, warp
Cross the lower section of idler roller 19, under the self gravitation effect of idler roller 19, idler roller 19
By mounting groove 4a can automatic slide downward, thin film thus can be in tensioning shape
State, thin film transfers out from the top of Left Drive roller 17；Meanwhile, idler roller 19 is at bullet
Under the effect of spring 21, the moderate pressure acting on thin film can be made, it is also possible to tensioning
Roller 19 slide downward plays the effect of buffering；
2, thin film through hole 3a on support two enters on support one, starts and rotates
Motor 7, the output shaft of rotary electric machine 7 operates and drives the drive pulley on output shaft
Wheel 8 operating, then under the effect of belt 10, drives driven pulley 9 to operate,
Traction Scroll 5 and rolling cylinder 6 operate eventually, and thin film is carried out rolling；
3, when the winding film on rolling cylinder 6 to certain thickness, until touching sensing
11, rotary electric machine 7, rotary electric machine just can be passed information to by inductive head 11
7 stop operating, thus realize winding on rolling cylinder 6 thin film of equal thickness；
4, stopping operating when rotary electric machine 7, the piston rod of telescopic cylinder 14 extends downwardly from,
Lower fastening strip 16 moves downward, until by the folder of the foamed film tensioning on the left of fixed plate 3
Tight between upper fastening strip 15 and lower fastening strip 16；
5, telescopic cylinder 14 stop motion, drives motor 23 to work, promotes slitting blade
22 motions, thus thin film is cut off, complete rolling cylinder 6 film；
6, change rolling cylinder 6, continue thin film is carried out rolling.
