AI Technical Summary
When using a thermoplastic printer, the edges of the PVC layer melt and roll up due to high temperature, resulting in high curling and poor yield.
A mobile phone decorative sticker including the PVC usage layer, the base layer and the anti-roll layer of the pattern to be printed is designed. The anti-roll layer is made of PET material, with a melting point temperature higher than 200°C, and is set along the width direction of the PVC layer to avoid high temperature melting and rolling.
Through the use of the anti-roll layer, the problem of the PVC usage layer melting and rolling up at high temperature of the thermoplastic printer is avoided, the working efficiency is improved, and the defective yield is reduced.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mobile phone decoration, in particular to a mobile phone decoration sticker. Background Art
[0002] Mobile phone decorative stickers are decorative paper used to decorate the back of mobile phones, making the phone more beautiful without affecting the feel of the phone. During the production process, a thermal printer is required to print patterns on the use layer of the mobile phone decorative stickers.
[0003] The material of the layer used for mobile phone decorative stickers is generally PVC, and the melting point of PVC is about 70℃, while the temperature of the printing area on the thermal printer can reach 200℃ during operation. This causes the edge to melt and curl up at high temperature the moment one end of the layer is extended into the printing area of the thermal printer, which in turn causes the entire layer to curl. In severe cases, the layer may stick to the thermal printer and cause damage. Utility Model Content
[0004] The purpose of the utility model is to provide a mobile phone decorative sticker which can solve the above-mentioned problem.
[0005] To achieve the above-mentioned purpose, an embodiment of the utility model provides a mobile phone decorative sticker, comprising a PVC use layer with a pattern to be printed and a supporting layer, the supporting layer being pasted on the lower end of the PVC use layer, and an anti-curling layer with a melting point higher than 200°C is provided on the upper end of the PVC use layer, the anti-curling layer is arranged along the width direction of the PVC use layer and is flush with one side of the PVC use layer.
[0006] Optionally, the anti-curl layer is a PET anti-curl layer.
[0007] Optionally, a protective layer is further included, and the protective layer is pasted on the upper end of the PVC use layer.
[0008] Compared with the prior art, the utility model has the beneficial effect that the anti-curling layer can prevent the end of the PVC layer that first extends into the printing area of the thermal printer from melting at high temperature and curling up, thereby improving work efficiency and reducing the defective product rate. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0011] Figure 2 It is a top view of the utility model.
[0012] In the figure: a PVC use layer 100, an anti-curling layer 200, a bottom support layer 300, and a protective layer 400. DETAILED DESCRIPTION
[0013] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.
[0014] In the description of the embodiments of the present invention, it should be understood that if there are directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, inside, outside, etc., the directions or positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of describing the embodiments of the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.
[0015] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.
[0016] In the embodiments of the present invention, unless otherwise clearly specified and limited, if there are terms such as "installed", "connected", "connected", "fixed", etc., they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection. It can be a mechanical connection or an electrical connection. It can be directly connected or indirectly connected through an intermediate medium. It can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.
[0017] like Figures 1-2As shown, the embodiment of the utility model provides a mobile phone decorative sticker, comprising a PVC use layer 100 with a pattern to be printed, a bottom layer 300 and a protective layer 400, wherein the bottom layer 300 is pasted on the lower end of the PVC use layer 100, and the protective layer 400 is pasted on the upper end of the PVC use layer 100. Further, the upper end of the PVC use layer 100 is provided with an anti-rolling layer 200 with a melting point higher than 200°C, and the anti-rolling layer 200 is preferably a PET anti-rolling layer, and the melting point of PET is about 250°C; the anti-rolling layer 200 is formed along the PVC use layer 10 0 is set in the width direction and is flush with one side of the PVC use layer 100. Specifically, the length of the PVC use layer 100 is the same as the width of the PVC use layer 100. When in use, the PVC use layer 100 is first extended into the printing area of the thermal printer where the anti-curling layer 200 is installed. Since the melting point of the anti-curling layer 200 is higher than 200°C, the anti-curling layer 200 can prevent the end of the PVC use layer 100 that first extends into the printing area of the thermal printer from melting at high temperature and rolling up, thereby improving work efficiency and reducing the defective product rate.
[0018] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
