After the gluing operation is finished, the rotating shaft 31 is continuously controlled to rotate 120 degrees clockwise, so that the paper tube 200 pasted with the double-sided adhesive tape 300 rotates to be aligned with the tensioning roller 2, and the film 100 conveyed on the tensioning roller 2 is pasted on the paper tube 200 through the double-sided adhesive tape 300; then, the two corresponding driving motors 761 are started to rotate synchronously, so as to drive the paper tube 200 to rotate, so as to wind the film 100. When the paper tube 200 is fully rolled with the film 100, the rotating shaft 31 is continuously driven to rotate 120 degrees clockwise; at this time, the paper tube 200 full of the film 100 is moved to align with the feeding mechanism 4, and the next paper tube 200 with the double-sided adhesive tape 300 attached thereto is moved to align with the tension roller 2, so as to attach the film 100 to the paper tube 200 through the adhesive tape layer 301 (as shown in fig. 24); at this time, the movable plate 632 positioned between the paper tube 200 fully wound with the film 100 and the paper tube 200 adhered with the film 100 moves to a position right above the cutter 61, and the film 100 is positioned between the movable plate 632 and the cutter 61, and the lifting assembly 62 is controlled to drive the cutter 61 to move upwards, so that the film 100 can be cut. The paper tube 200 close to the tension roller 2 is controlled to rotate while the film 100 is cut off, so that the next winding operation can be automatically carried out; and then the first electromagnets 75 at the two ends of the paper tube 200 fully rolled with the film 100 are controlled to be electrified to attract the corresponding two clamping sleeves 73 to move backwards, so that the paper tube 200 fully rolled with the film 100 automatically falls onto the conveying belt 8, and then the feeding is continuously carried out through the feeding mechanism 4.
