Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] like Figure 1~4 As shown, this embodiment provides a film slitting and winding method, which requires an existing slitter to cooperate with the cutting mechanism 1 of this embodiment. The structure of the existing slitting machine is an existing mature technology, and will not be described in detail here.
[0025] The slitting and winding method of above-mentioned film comprises the following steps:
[0026] (1) The window film 100 is transported forward from the large roll of window film 2, the front edge of the window film 100 is cut off as a whole, and then the release film layer 10 at the front edge of the window film 100 is cut off by 1 to 5 cm to expose the installation glue layer 20;
[0027] (2) Adhere the installation adhesive layer 20 on the outer peripheral wall of the reel 3 along the axial direction of the reel 3, and t...

Abstract
The invention relates to a film slitting and winding method, which comprises the following steps: conveying a window film forwards from a big roll roll of window film, integrally cutting off the front edge of the window film, and cutting off a release film layer at the front edge of the window film by 1-5cm so as to expose a mounting adhesive layer; adhering the mounting adhesive layer to the peripheral wall of a winding drum in the axial direction of the winding drum, and then winding the window film on the winding drum layer by layer; and after the winding thickness or length of the window film on the winding drum meets the requirement, cutting off the window film integrally. According to the film slitting and winding method provided by the invention, the characteristics of the window film are utilized, before the window film is wound, the release film layer at the front edge of the window film is cut by 1-5cm, the mounting adhesive layer is exposed, then the front edge of the window film is fixed to the winding drum through the exposed mounting adhesive layer of the window film, and then the window film is wound, since a double-sided adhesive layer is no longer needed to be pasted when winding, the thickness difference of the contact position of the window film and the winding drum is eliminated, so that generation of protrusions is avoided, the problem of deformation of the window film is solved, large-area waste of the window film is avoided, and the utilization rate of the window film is effectively increased.
Description
technical field [0001] The invention relates to the technical field of film production, in particular to a film cutting and winding method. Background technique [0002] Window film products have broad market prospects due to their energy saving, environmental protection and easy installation. Most of them are used in construction, automobile, security and other industries, with anti-ultraviolet, heat insulation and explosion-proof functions. [0003] figure 1 The structure of a traditional window film is shown, which has a release film layer 10 , an installation adhesive layer 20 , a core functional layer 30 , and a wear-resistant layer 40 adhered together in sequence. Among them, the release film layer is to isolate and protect the installation adhesive layer. In actual use, the release film layer needs to be removed, and the window film is adhered to the window glass by the installation adhesive layer; the core functional layer has anti-ultraviolet, insulation Layers o...
