Detailed Description
The utility model is further described with reference to the following figures and detailed description.
The gluing mechanism 3 is used for gluing two double-sided adhesive tapes to corresponding areas of the base film 1.
As shown in fig. 1 and 2, the rubberizing mechanism 3 comprises a frame 21, and the frame 21 is sequentially provided with a pinch roller set and a wind-up roller 25 according to the conveying direction of the base film 1; meanwhile, a double-sided tape unwinding roller is further mounted on the frame 21 and used for outputting double-sided tapes. The folded base film 1 is input from one end of the gluing mechanism 3, the double-sided adhesive tape on the double-sided adhesive tape unwinding roller is adhered to the folded base film 1, and finally output and wound on the winding roller 25 through the compression roller set.
The two double-sided tape unwinding rollers are a first double-sided tape unwinding roller 26 wound around the first double-sided tape 11 and a second double-sided tape unwinding roller 27 wound around the second double-sided tape 12.
The pressing roller group is provided with three groups, namely a first pressing roller group 22, a second pressing roller group 23 and a third pressing roller group 24, wherein the first pressing roller group 22 is used for pressing the first double-sided adhesive tape 11 and the base film 1, and the second pressing roller group 23 is used for pressing the second double-sided adhesive tape 12 and the base film 1; the third press roller group 24 is for simultaneously pressing the first double-sided adhesive tape 11, the second double-sided adhesive tape 12 and the base film 1.
Each group of pressing roller sets consists of two pressing rollers, and the base film 1 adhered with the double-sided adhesive tape passes between the two pressing rollers, so that the double-sided adhesive tape and the base film 1 are adhered more closely. The roller center distance between the two compression rollers is adjustable; the surface coating of the pressing roller is made of Teflon materials, and the double-sided adhesive tape is stuck to the surface of the pressing roller after being stuck to be inclined, so that the double-sided adhesive tape can be conveniently peeled off from the pressing roller.
The third pressing roller group 24 consists of two pressing rollers, and the base film 1 for adhering the double-sided adhesive tape is arranged between the two pressing rollers in a penetrating way; because the base film 1 is folded, the first area 14 is overlapped with the second area 15, and the third area 16 is not overlapped, the thicknesses of different areas of the base film 1 are different, when winding, if a single-layer area is wound tightly, deformation can occur due to the larger thickness of the overlapped area, the base film 1 can be deviated, and the side edge of each circle of the base film 1 is not overlapped with the side edge of the previous circle; therefore, the deviation of the base film 1 is avoided by arranging the third pinch roller set 24. The specific structure of the third compression roller set 24 is as follows:
as shown in fig. 1, in one of the pressure rollers, the pressure roller is divided into two parts, a first pressure roller section 241 and a second pressure roller section 242, in the axial direction, and the roller diameter of the first pressure roller section 241 is larger than that of the second pressure roller section 242; the overlapped area, i.e. the thicker part, on the base film 1 is arranged between the first pinch roller sections 241 of the two pinch rollers in a penetrating way, and the single-layer area, i.e. the thinner part, on the base film 1 is arranged between the second pinch roller sections 242 of the two pinch rollers in a penetrating way; therefore, the thicker area is tightly wound, the single-layer area is not tightly wound, and the deformation and the deviation can not occur.
The first double-sided tape 11 is wound on the first double-sided tape unwinding roller 26, and the second double-sided tape 12 is wound on the second double-sided tape unwinding roller 27; the first double-sided adhesive tape 11 fed out from the first double-sided adhesive feeding roller 26 is stuck to the first region 14 of the folded base film 1, and the base film 1 with the first double-sided adhesive tape 11 stuck thereto is fed into the first pinch roller group 22; the second double-sided tape 12 fed from the second double-sided tape feeding roller 27 is fed to the second pinch roller set 23 on the third region 16 of the base film 1 fed from the first pinch roller set 22, and fed to the third pinch roller set 24, and finally fed and wound on the winding roller 25.
The above is the preferred embodiment of the present invention, and several other simple substitutions and modifications made on the premise of the inventive concept should be considered as falling into the protection scope of the present invention.
