edge of the PVC film roll, the inclined rod 203 can be rotated on the bearing block 201 through the motor I204, thereby, the PVC film is rotated around the axis direction of the inclined rod 203, the PVC film in the vertical direction can be driven to incline and simultaneously rotate, at the moment, under the action of the spring III 9, the extending column 8 can slide on the fixed column 7 in a reciprocating way, the extending column 8 keeps the state of collision against the protective film, so that the protective film can be wound on the PVC film roll in a more fitting way, through the design of the blade 15, after the PVC film roll is wound, the mounting block 11 slides to the opening end of the sliding groove 10 through the electric push rod V12, so that the blade 15 moves to the outside of the rotating roller 606, so that the blade is contacted with the protective film, at the moment, the blade 15 slides on the mounting block 11 through the electric slide block III 14, thereby the cutting of the protective film can be realized, the cutting of the protective film is convenient, the protective film is not required to be cut by a worker, thereby the use of the worker is facilitated, through the design of joint spare 16, when being about to accomplish the winding to the PVC membrane book, can make installation piece 11 slide to its open end at sliding tray 10 through five 12 electric putter, the PVC membrane book rotates the winding protection film, it makes sliding tray 10 be located under spout 1603 to drive live-rollers 606 and rotate, thereby can make joint piece 1601 insert establish to spout 1603 in and with mounting bracket 605 looks joint under the effect of spring four 1602, thereby avoid rolling up the winding completion back to the PVC membrane, sliding tray 10 is just rolling up to the PVC membrane, make blade 15 remove to live-rollers 606 outside, when cutting the protection film, PVC membrane is rolled up to winding protection film and PVC membrane to the broken PVC membrane book to blade 15, cause the condition that PVC membrane and protection film damaged.
