The first pressure roller 43 presses the packaging film 421 against the web 6 due to the action of the blow-up bar 45; then the lifting driving device drives the pressing wheel 35 to descend, so that the pressing wheel 35 is pressed against the outer peripheral surface of the coiled material 6, the double-sided adhesive tape 321 is unreeled under the traction of the pressing wheel 35, and the double-sided adhesive tape 333 positioned at the position of the adhesive tape positioning line is pasted on the coiled material 6; the coiled material driving device 2 and the rolling mechanism 33 act simultaneously, the double-sided adhesive tape coiled material 6 on the double-sided adhesive tape 321 is adhered along with the rotation of the coiled material 6, when the adhering length of the double-sided adhesive tape 333 reaches a preset length (5-10 cm), the braking mechanism 34 brakes the double-sided adhesive tape 321 to limit the rotation of the double-sided adhesive tape 321 to stop unwinding the double-sided adhesive tape 321, the rolling mechanism 33 stops rolling the isolation tape 331, the double-sided adhesive tape is cut off at the fixed adhesive line 38 under the traction and pulling action of the coiled material 6, the lifting driving device drives the pressing wheel 35 to ascend and leave the coiled material 6, then the double-sided adhesive tape is about to pass through the first pressing wheel 43, the upper film driving device 7 is started, the packaging film 421 is also unfolded under the traction of the upper film driving device 7 and attached to the surface of the coiled material 6, the packaging film 421 is fixed on the coiled material 6 through the double-sided adhesive tape 333, the coiled material 6 is tightly embraced by the packaging film 421 after being wound for several circles, then the first power module 11 rises to make the first press roller 43 and the second press roller 44 leave the coiled material 6, then the second power module 12 drives the chassis 16 to do transverse reciprocating motion to make the packaging film move and wind on the coiled material 6, after the coiled material 6 winds a sufficient amount of the packaging film 421, the second power module 12 and the coiled material driving device 2 stop working, a section of the tensioned packaging film 421 is formed between the first press roller 43 and the coiled material 6, then the film cutting driving mechanism 52 drives the electric heating cutting strip 51 to swing around the axis of the first press roller 43 to cut the packaging film, and the heated electric heating cutting strip 51 can rapidly fuse the packaging film. Finally, the first power module 11 and the second power module 12 drive the chassis 16 to return to the initial position.

It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
