The working principle is as follows: with reference to fig. 1 to 6, the preparation required before use is as follows: first, a film roll 60 is mounted on a mandrel 21 of a film supply mechanism 20; secondly, the paper tube 70 is supported by the left top tube part 51 and the right top tube part 52 of the clip tube rolling mechanism 50 so as to fix the paper tube 70; thirdly, the film cutting knife 31 is retreated to the initial position at the left side. When the preservative film is used, the film is firstly pulled out from the film roll 60 and is directly adhered to the paper tube 70 (note: the film has certain adhesiveness because the film is made of the same PE material as the preservative film); then, the first stepping motor 511 of the left top cylinder part 51 of the cartridge winding mechanism 50 drives the left top block 514 to rotate, because the right top block 522 can freely rotate at the telescopic rod of the top cylinder 521, the left top block 514 can drive the paper tube 70 and the right top block 522 to rotate together when rotating, the paper tube 70 winds the film when rotating, and when the length value of the film wound on the paper tube 70 reaches a specific length range, as shown in fig. 4 and 5, the left film pressing cylinder 41 and the right film pressing cylinder 42 of the film pressing mechanism 40 simultaneously drive the U-shaped film pressing block 43 thereof to press the film on the lower surface of the main board frame 32; subsequently, the film cutting mechanism 30 drives the film cutting knife 31 to perform horizontal transverse movement, thereby cutting the film. After the film is cut off, the first stepping motor 511 of the cartridge winding mechanism 50 drives the paper cartridge 70 to rotate at a low speed, so as to wind the residual film at the paper cartridge 70; after the winding is completed, the top cylinder 521 of the right top cylinder part 52 drives the right top block 522 to retract, and the production worker can take off the paper cylinder 70 wrapped with the film and then continue to load a new paper cylinder 70, and the above operations are repeated.
