[0032] Reference below Figure 1-Figure 6 The winding device 10 of the adhesive film 11 according to the embodiment of the utility model comprises: a winding roller 100 , a roll-splitting cutter 200 , at least two winding shafts 300 and an air knife assembly 400 .
[0033] Specifically, the winding roller 100 is used to introduce the adhesive film 11; the splitting cutter 200 is arranged on the upper side of the winding roller 100, and the splitting cutter 200 is used to split the adhesive film 11; the split adhesive film 11 is transported to at least one winding shaft 300 for winding; the wind knife assembly 400 is arranged on the lower side of the winding roller 100, and the air outlet side of the wind knife assembly 400 is arranged opposite to the adhesive film 11.
[0034] It should be noted that during the use of the adhesive film 11, it is suitable to introduce the adhesive film 11 through the winding roller 100, and the adhesive film 11 can be rolled up by the roll cutting knife 200, so that the rolled film 11 can be rolled up to a specified length according to the design for subsequent use. After the adhesive film 11 is cut, it is suitable to transport the adhesive film 11 to one of the winding shafts 300 for winding, and after a proper amount of adhesive film 11 is rolled up on the winding shaft 300, use the roll cutting knife 200 to split it, and transport the adhesive film 11 to another winding shaft 300 for subsequent winding.
[0035] During the transportation of the film 11 on the winding roller 100, the film 11 may stick to the winding roller 100, which may affect the subsequent transportation and winding of the film 11. Therefore, an air knife assembly 400 is provided on the lower side of the winding roller 100, and the air outlet side of the air knife assembly 400 is provided in the circumferential direction of the winding roller 100, so that during the transportation of the film 11 on the winding roller 100, the film 11 that may be attached to the winding roller 100 can be peeled off from the winding roller 100 by the air knife assembly 400, so that the film 11 can be better transferred to the winding shaft 300 for winding according to the design, so as to improve the performance and service life of the winding device 10 of the film 11.
[0036] According to the winding device 10 of the adhesive film 11 of the embodiment of the utility model, a wind knife assembly 400 is provided at the bottom of the winding roller 100. Since the air outlet direction of the wind knife assembly 400 is toward the circumferential direction of the winding roller 100, the wind knife assembly 400 can peel the adhesive film 11 wound on the winding roller 100 from the winding roller 100, and allow the adhesive film 11 to be transferred to the winding shaft 300 for winding, so as to more reliably realize the separation and winding of the adhesive film 11.
[0037] In some embodiments, an air inlet 401 and an air outlet 402 are respectively provided on both sides of the wind knife assembly 400. The air inlet 401 is connected to a driving member, and the driving member is used to drive the air flow into the air inlet 401. The air outlet 402 has an air outlet direction in the circumferential direction of the winding roller 100.
[0038] In this way, by providing an air inlet 401 and an air outlet 402 on both sides of the wind knife assembly 400, the air inlet 401 is suitable for connecting with a driving member, so that the driving member is suitable for driving the airflow to enter the wind knife assembly 400 through the air inlet 401, and to be discharged through the air outlet 402 provided on the other side of the wind knife assembly 400, so as to form the use performance of the wind knife assembly 400.

[0040] In some embodiments, both ends of the air knife assembly 400 are sealed by hot melt or welding. That is, in the process of constructing the air knife assembly 400, it is suitable to use hot melt sealing or welding sealing to seal both ends of the air knife assembly 400, so that the structural construction process of the air duct assembly is simpler, and the structure of the constructed air flow channel 403 is more reliable, so that the air flow can flow more reliably according to the design, so that the air knife assembly 400 can more reliably peel the adhesive film 11 from the winding roller 100.
[0041] In some embodiments, the air outlet 402 is arranged in a plurality of intervals on the wind knife assembly 400.

[0045] In some embodiments, the fixing nut 410 is welded to both ends of the wind knife assembly 400. In this way, by connecting the fixing nut 410 to both ends of the wind knife assembly 400 by welding, not only can the setting of the fixing nut 410 at the end of the wind knife assembly 400 be more reliable, but also the fixing nut 410 can be used as designed, so that the performance of the winding device 10 is improved.
[0046] In some embodiments, the air knife assembly 400 is made of metal. Therefore, by setting the air knife assembly 400 to be made of metal, not only can the cost be reduced, but also the structural setting of the air knife assembly 400 can be made more reliable, so as to improve the performance and service life of the air knife assembly 400, so that the winding device 10 can wind up the film 11 according to the design, so that the performance of the winding device 10 is improved.
