the second vertical plate 12 is provided with a U-shaped notch 121, and the second vertical plate 12 is provided with a U-shaped sponge holder 122 on the U-shaped notch 121. The preservative film to be cut is put in from the U-shaped notch 121, and the sponge support 122 is used for flexibly supporting the preservative film.

After the adjustment preparation work of the clamping adjustment in the step S1 and the fixed-length adjustment in the step S2 is completed, the formal preservative film cutting operation can be performed, and when the preservative film placing operation in the step S3 is performed, the preservative film to be cut is horizontally placed from the U-shaped notch 121, passes through the two auxiliary guide mechanisms 6, rolls along the guide clamping rod 225, and is inserted into the clamping mechanism 2 to perform one-end clamping, and one end of the preservative film is pressed against the side wall of the first vertical plate 11.

Then, step S4 is just led and is held the clamp operation, and is concrete, start leading positive cylinder 61 of both sides simultaneously and drive articulated bedplate 62 and be close to towards the plastic wrap, along with being close to, embrace the clamp roller 633 will be rolling forward along pasting the plastic wrap face of cylinder, two are embraced the arm lock 631 and will open thereupon, under the pulling force effect of extension spring 632, the plastic wrap will be horizontal state and is embraced the clamp and press from both sides between two sets of holding clamp leading subassemblies 63 of mutually supporting, two supplementary leading positive mechanisms 6 provide on the one hand and distribute in the holding clamp bearing support of cutting blade 54 both sides to the plastic wrap. The cutting blade 54 can be conveniently applied with force downwards for cutting, and on the other hand, the preservative film is ensured to be cut in a horizontal state, and the inclination of the cut is avoided.

The slitting mechanism 5 further comprises a lifting cylinder 51, a tool apron 52 and a cutting driving motor 53, the lifting cylinder 51 is vertically and fixedly installed at the top end of the portal frame 43 through bolts, the tool apron 52 is fixedly installed at the output end of the lifting cylinder 51 in a welding mode, the top end of the tool apron 52 is provided with two guide pillars 521, the two guide pillars 521 are distributed on two sides of the lifting cylinder 51, the two guide pillars 521 and the portal frame 43 are vertically arranged in a sliding mode, the cutting driving motor 53 is fixedly installed on the side wall of the tool apron 52 through a motor fixing plate, a driving gear 531 is arranged on an output shaft of the cutting driving motor 53, a cutting blade 54 is rotatably installed on the tool apron 52, and a rotating shaft end of.

When the step S5 vertical slitting operation is performed, specifically, on one hand, the cutting driving motor 53 is started to drive the driving gear 531 to rotate, the driving gear 531 drives the driven gear 541 engaged with the driving gear 531 to drive the cutting blade 54 to rotate, on the other hand, the lifting cylinder 51 pushes the knife holder 52 to move vertically downward, so as to drive the rotating cutting blade 54 to move vertically downward to complete slitting of the preservative film, and after slitting is completed, the preservative film is divided into two sections.

Material returned mechanism 3 sets up on the lateral wall of riser 11 No. one, material returned mechanism 3 is including stretching into and passing the trident material returned board 33 of drum 21, it needs to explain, when material returned cylinder 32 is in initial output state, the terminal surface of trident material returned board 33 just flushes with the inside wall face of riser 11 No. one, material returned mechanism 3 still includes cylinder mount 31 and material returned cylinder 32, cylinder mount 31 welded fastening installs on the lateral wall of riser 11 No. one, material returned cylinder 32 passes through bolt fixed mounting on cylinder mount 31, trident material returned board 33 passes through screw fixed mounting at material returned cylinder 32's output.
