Step 1: opening the upper cover plate 5 at 1 top of roller seat, the drive shaft 3 of 2 two sides of live-roller be placed in groove 7, will Retention bead 6 is inserted into the slot opened up on roller seat 1, covers tightly upper cover plate 5, film is placed on side live-roller 2, using Live-roller 2 surface in the other side is wound into after two guide rollers 131, the spring stack 40 on 38 surface of fixed plate cooperates baffle 41 that will furl The film on place 2 surface of live-roller is squeezed, and 9 output shaft of first motor drives screw rod 11 to rotate, and screw rod 11 cooperates 12 bottom of side frame The threaded hole in portion rotates, and then drives side frame 12 to prolong upright bar 10 and move up and down, and two side frames 12 are by mounting plate 13 with action-oriented Roller 131 is gone up and down, and the opening and closing degree of film is adjusted；

Step 2: in 14 surface sliding guide sleeve 28 of guide rod after the completion of adjusting, film is worn to two rollings in material hole 251 Between wheel 25, fastening bolt 27 is rotated, will test and fixed between plate 15 and guide rod 14, rotating boss bolt 18 is adjusted to boss Bolt 18 is in contact at the top of lever compression bar 20 close to switch 19, and boss bolt 18 is fixed rotating boss nut 17；

Step 3: drive shaft 3 cooperates the rolling bearing 4 of two sides to rotate, and drive shaft 3 drives the rotation retracting film of live-roller 2, When the thickened film thickness between two idler wheels 25, the idler wheel 25 of the upward upper end of film, the idler wheel 25 of upper end is with moving axis It holds seat 23 and prolongs the positioning rotation of bearing 24, and then bearing block 23 drives lever compression bar 20 to start turning, spring 22 further stretches, thick stick It is not contacted close to switch 19 with 18 bottom of boss bolt on bar compression bar 20, signal is passed into monolithic by conducting wire close to switch 19 Machine, single-chip microcontroller control relay and open the second motor 35, and 35 output shaft of the second motor drives side gear 34 to rotate, two side gears The groove face rotation of 34 cooperation 31 two sides of lifter plate, lifter plate 31 prolong the decline of positive stop strip 32, and lifter plate 31 drives the connection of bottom Bar 36 declines, and the cutting line 37 between connecting rod 36 cuts film, after the completion of retracting by fixed plate 38 and baffle 41 it Between bayonet lock 39 it is mutually stuck, open upper cover plate 5, take out live-roller 2.
