Furthermore, the trimming device 7 includes a cutting wheel driven by a power unit, which is driven by a cylinder to press down and cut the edge of the base film.

[0024] To further simplify the structure, the working platform 3 is a non-continuous platform, including a first separation platform 16 and a second separation platform 17 located below the first negative pressure suction plate 14 and the second negative pressure suction plate 15, and an adhesive platform 18 located below the labeling mechanism 5.

[0028] This embodiment uses the following double-sided adhesive assembly: The double-sided adhesive assembly includes a first adhesive and a second adhesive arranged sequentially.

The second adhesive has one adhesive surface and one substrate surface. Its adhesive surface is bonded to the base film corresponding to the second negative pressure suction plate 15, and its substrate surface is bonded to the first adhesive. In use, the first and second adhesives are separated to separate the front and rear packaging films. The front and rear ends of each packaging film are respectively bonded with the first adhesive and the second adhesive. The first adhesive can be used as a sealing adhesive.

[0029] In this embodiment, the frame 1 adopts a modular splicing structure. The frame 1 includes a front frame 27 and a rear frame 28. The first negative pressure suction plate 14 of the feeding mechanism 2 and the separation mechanism 4 are both located on the front frame 27. The second negative pressure suction plate 15, the separation device 12, the adhesive application device 13, the labeling mechanism 5, and the receiving mechanism 6 of the separation mechanism 4 are all located on the rear frame 28. After the front frame 27 and the rear frame 28 are spliced, a gap is formed between the first separation platform 16 and the second separation platform 17. The above-mentioned detachable front and rear frame 28 design allows for the partitioned arrangement of key functional modules. This modular design facilitates the manufacturing, transportation, and on-site installation and commissioning of the equipment, reducing the complexity and cost of manufacturing and deployment.

[0030] The working process of this embodiment is as follows: the base film roll is installed on the unpowered unwinding device of the unwinding mechanism 2, the film head is led out, and passes sequentially through the gap between the first conveying roller group 19, the gap between the first separation platform 16 and the first negative pressure suction plate 14, the gap between the second negative pressure suction plate 15 and the second separation platform 17, the second conveying roller group 20 and the pasting platform 18, and is finally fixed on the winding device core of the winding mechanism 6. The power device of the winding mechanism 6 drives the winding device to rotate slowly, pulling the base film forward. During this process, the first conveying roller group 19 and the second conveying roller group 20 rotate synchronously to ensure that the base film is stably tensioned.

[0031] After the device is started, the control system runs a complete work cycle according to the preset program: Adhesive application: The flipping cylinders 26 on both sides of the first negative pressure suction plate 14 and the second negative pressure suction plate 15 operate simultaneously. The piston rods of the tilted flipping cylinders 26 extend or retract, driving the first negative pressure suction plate 14 and the second negative pressure suction plate 15 to rotate 90° upwards about their hinge axis with the frame 1 via the hinge point. This action changes the adsorbed ends of the two film sections from a horizontal state to a vertical and opposite state; the adhesive application device 13 located above the work platform 3 starts working, and its adhesive application linear drive 23 drives the adhesive application machine 24 to move laterally from the initial outer position to above the work area. The adhesive application machine 24 performs an action, moving laterally from one side of the work platform 3 to the other side, and smoothly attaches one section of the double-sided adhesive assembly to the base film adsorbed by the second negative pressure suction plate 15.

[0032] Docking: The first negative pressure suction plate 14 moves the base film it adsorbs towards the second negative pressure suction plate 15, adhering the base film to the double-sided adhesive assembly, so that the two adjacent base films are connected as one. Then, the second negative pressure suction plate 15 releases the base film and moves away from the first negative pressure suction plate 14 to avoid the first negative pressure suction plate 14. The first negative pressure suction plate 14 flips down to press the vertical base film down to a horizontal state, and then releases the base film. The first negative pressure suction plate 14 and the second negative pressure suction plate 15 are reset.

[0033] Labeling: The winding device is activated, pulling the bonded continuous base film forward by a set length (i.e., the length of one finished film segment), allowing the joined base film to pass through the subsequent workstation. During the pulling process, when the base film passes under the labeling mechanism 5, one label applicator applies one large label, and another label applicator applies four small labels. Simultaneously, the edges of the base film pass through the trimming device 7. The cutting wheel of the trimming device 7 is pressed to the working position under the drive of a cylinder and rotates at high speed driven by a power unit, precisely cutting off excess burrs on both sides of the base film to ensure a consistent width of the finished product. The waste generated during cutting is promptly sucked in by the dust suction hood 8 above and collected through the dust suction pipe to the dust collection device for treatment.

[0034] Cutting: The winding device stops, and the first negative pressure suction plate 14 and the second negative pressure suction plate 15 in the separation mechanism 4 are activated, generating negative pressure to firmly adsorb and fix the base film below. The separation linear drive 21 below the work platform 3 drives the cutting blade 22 to move laterally from the outside to the separation groove 11 area and laterally penetrate the separation groove 11, completely cutting the base film laterally.

[0035] This completes one cycle. After multiple cycles, the continuous and regular cotton baling film is tightly and neatly wound into a finished large roll by the winding device.

[0036] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
