[0025] The driving mechanism on the adhesive tape pressing roller device 30 includes a first connecting seat 32 and a second connecting seat 33 fixedly connected with the wallboard 1, the first connecting seat 32 is fixedly connected with a pressing roller driving cylinder 34, the second connecting seat 33 is pin-connected with a rocker arm 35, the middle of the rocker arm 35 is pin-connected with the movable end of the pressing roller driving cylinder 34, and the adhesive tape pressing roller 31 is connected to the end of the rocker arm 35.

[0026] Working process:

[0027] After the film 8 is cut by the cutting device 100, it is wound on the winding shaft 3 in the winding station after passing through the winding pressing roller 4. After the winding shaft in the winding station winds enough film, the winding shaft in the winding station becomes the winding shaft in the discharging station by turning over the winding frame 2, and the winding shaft in the discharging station becomes the winding shaft in the winding station, so that the winding shaft with the full film roll is discharged to the discharging station and the new empty winding roller starts to wind the film in the winding station.

[0028] The double-sided adhesive tape roll is set on the adhesive tape unwinding shaft 12 and unwound therefrom. The pulled-out adhesive tape 20 is guided by the release layer winding shaft 13 and the adhesive tape guide wheel 14 in turn, and then transferred to the head roller 15. After passing through the head roller 15, the adhesive tape 20 is wound by the release layer winding shaft 13. When the adhesive tape 20 passes through the head roller 15, the adhesive layer of the double-sided adhesive tape faces outward. When the adhesive tape is needed, the head roller 15 presses the film 8 passing below the winding pressing roller 4 upward, and the film 8 drives the head roller 15 to rotate to realize the pasting of the adhesive layer 21 on the film. At this time, the rotation of the release layer winding shaft 13 is driven by the friction force generated when the adhesive tape 20 is unwound upward, so that the release layer 22 is finally realized by the friction force.

[0029] Before the take-up shaft 3 moves from the take-up position to the unloading position, the take-up pressure roller 4 moves away from the take-up shaft 3. When the take-up shaft 3 moves from the take-up position to the unloading position, the support beam 7 of the tape supply device 10 moves upward under the drive of the lifting cylinder 6, causing the head roller 15 on the tape supply device 10 to press upward and contact the film 8 passing the bottom of the take-up pressure roller 4. After contact, due to the friction generated by the film 8 moving forward on the head roller 15, the head roller 15 will be driven to rotate. The rotation of the head roller 15 will drive the tape 20 to automatically wind through the take-up position. The adhesive layer 21 of double-sided adhesive tape is transferred to the outer surface of the film 8 at the bottom of the pressure roller 4. The length of the transferred adhesive layer 21 is controlled so that its tail end can stick to the new empty take-up shaft 3 transferred to the take-up station. After the adhesive layer 21 is long enough, the tape cutting head 17 driven by the tape cutting cylinder 16 performs a preliminary cut on the adhesive layer 21. Then, the support beam 7 moves down with the tape supply device 10 and completely breaks the cut point of the adhesive layer 21 on the tape 20. The release layer 22 peeled off from the tape 20 during the adhesive layer application process is wound up by the release layer take-up shaft 13.

[0030] After a new empty take-up reel 3 arrives at the winding station, the winding pressure roller 4 rests against the new empty take-up reel 3 again. Then, the film cutter 5 cuts the film 8, which spans between the unloading station and the winding station, downwards (the front end of the film is wound on the fully rolled take-up reel at the unloading station, and its rear end is already resting on the new empty take-up reel at the winding station), cutting the section of film with adhesive layer 21 in half. At this time, the tape pressure roller 31 next to the take-up reel 3 at the unloading station presses down on the take-up reel 3, allowing the take-up reel 3 at the unloading station to continue winding several times while being pressed down by the tape pressure roller 31. This allows the tail end of the film 8 to be smoothly wound and fixed to the film roll under the adhesive effect of the adhesive layer 21. The new empty take-up reel 3 at the winding station is already adhered to the roller surface by its own adhesive layer 21 as soon as the head of the film 8 first contacts the roller surface, and it is firmly adhered as the take-up begins.

[0031] This utility model discloses a four-axis high-speed slitting machine capable of automatically applying adhesive tape. Its ingenious structure, through the coordination of a double-layer, double-station winding structure, a winding pressure roller device, a tape supply device, and a tape pressure roller device, allows for the automatic application of a section of tape onto the film after winding. This tape, after being cut, has two halves: one half is used to bond and fix the film tail to the film roll at the end of winding, ensuring the roll is securely fixed and does not unravel; the other half is used to quickly fix the film to a new winding shaft. This achieves the effect of effectively fixing both the beginning and end of the film roll, with fast fixing speed, high automation, and good fixing quality, significantly improving production speed and the winding quality of film rolls with broken beginnings and ends. The tape supply device is also ingeniously designed, enabling unpowered unwinding and release layer winding, making it highly practical and worthy of promotion.
