Description

Technical Field

[0001] The utility model relates to the field technology of plastic surface shell covered texture film production, in particular to a plastic surface shell covered texture film structure, which is mainly used for proofing products. Background Art

[0002] For plastic cover products with textured surface design, when proofing is required, if a textured mold is used to form a plastic cover with a corresponding texture on the surface, it is necessary to first design and produce the corresponding textured mold, or at least make partial changes based on the molding mold of the original smooth plastic cover. This is costly and takes a long time, and it is difficult to respond quickly to sample display needs. Obviously, it is not an ideal measure for the situation where it is only in the early design and proofing stage and whether mass production and orders will be carried out later is undecided.

[0003] Some methods also use 3D printing to produce a three-dimensional textured adhesive film, which is then pasted on the surface of the original plastic shell without texture. However, in this method, the adhesive film is thicker and is mainly suitable for flat surfaces with regular shapes. If it is pasted on a non-flat and irregular surface (with folded edges, corners, etc.), it is difficult to follow the shape and adhere firmly, resulting in inapplicability.

[0004] A new technical solution needs to be studied to solve the above problems. Utility Model Content

[0005] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a plastic surface shell covered with a textured film structure, which can realize the rapid and low-cost production of proofing products covered with the textured film.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A plastic shell covered with a textured film structure, comprising:

[0008] A plastic face shell, comprising a shell body and a side portion integrally connected to the periphery of the shell body; the outer surface of the shell body is an outer plane or an outer arc surface, and the side portion integrally extends inward from the periphery of the shell body away from the outer plane;

[0009] A textured film comprises a cloth substrate and a first soft adhesive coating coated on one side surface of the cloth substrate, a second soft adhesive coating is coated on the outer surface of the first soft adhesive coating, and a third soft adhesive coating is coated on the outer surface of the second soft adhesive coating; the outer surface of the third soft adhesive coating is embossed to form a textured surface;

[0010] The outer plane or outer curved surface is coated with water-based PU glue, the texture film is covered and fixed on the outer surface, the texture surface is arranged outward, and the texture film is covered and extended along the outer surface of the side portion and folded back to the inner surface of the side portion and glued and fixed.

[0011] As a preferred solution, the cloth substrate is a porous fabric.

[0012] As a preferred solution, the other surface of the cloth substrate is coated with a fourth soft adhesive coating.

[0013] As a preferred solution, a fifth soft adhesive coating is coated on the outer surface of the fourth soft adhesive coating.

[0014] As a preferred solution, the cloth base material is an elastic fabric.

[0015] Compared with the prior art, the utility model has obvious advantages and beneficial effects.

[0026] Please refer to Figures 1 to 9 As shown, it shows the specific structure of various embodiments of the present utility model.

[0027] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0028] A plastic surface shell covered with a textured film structure is mainly suitable for rapid proofing products, especially for existing smooth plastic surface shells, where it is necessary to present plastic surface shell samples with textured surfaces to customers. Through the technical solution of the utility model, rapid and low-cost production of proofing products covered with textured films can be achieved.

[0029] Specifically, the plastic surface shell covered with texture film structure includes a plastic surface shell 10 and a texture film 20 .

[0030] The plastic shell 10 generally refers to an existing smooth plastic shell. In actual production, an existing plastic shell 10 with other textures may also be used. The plastic shell 10 comprises a shell body 11 and a side portion 12 integrally connected to the periphery of the shell body 11; the outer surface of the shell body 11 is an outer plane 111, and the side portion 12 integrally extends from the periphery of the shell body 11 inwardly away from the outer plane 111.

[0031] The texture film 20 includes a cloth substrate 21 and a first soft adhesive coating 22 coated on one side of the cloth substrate 21. After the first soft adhesive coating 22 is dried, a second soft adhesive coating 23 is coated on the outer surface of the first soft adhesive coating 22. After the second soft adhesive coating 23 is dried, a third soft adhesive coating 24 is coated on the outer surface of the second soft adhesive coating 23. The outer surface of the third soft adhesive coating 24 is embossed to form a texture surface 25. The cloth substrate 21 is a porous fabric, which is conducive to the combination of the water-based PU adhesive 30.

[0032] A water-based PU glue 30 is applied on the outer plane of the plastic cover 10, and the other side surface of the cloth substrate 21 is bonded to the outer surface through the water-based PU glue 30, so that the texture film 20 is covered and fixed on the outer surface, the texture surface 25 is arranged outward, and the texture film 20 is covered and extended along the outer surface of the side edge and folded back to the inner surface of the side edge for bonding and fixing. Generally, before applying the water-based PU glue 30, an interface agent can be applied to at least the outer plane, which is equivalent to surface treatment, which is conducive to subsequent bonding.

[0033] In another embodiment, the other side surface of the cloth substrate 21 is coated with a fourth soft adhesive coating 26, or, further, after the fourth soft adhesive coating 26 is dried, a fifth soft adhesive coating 27 is coated on the outer surface of the fourth soft adhesive coating 26. The fourth soft adhesive coating 26, or the fourth soft adhesive coating 26 and the fifth soft adhesive coating 27 are provided, so that the texture film 20 and the plastic cover 10 are more reliably combined through the water-based PU adhesive 30.

[0034] In other embodiments, the cloth substrate 21 is an elastic fabric with only a small amount of elasticity.

[0035] The first soft glue coating 22, the second soft glue coating 23, the third soft glue coating 24, the fourth soft glue coating 26, and the fifth soft glue coating 27 can all be made of soft glue materials such as TPU. When making them, the soft glue liquid is applied to the surface. For factories, there are generally a variety of optional embossing jigs. Therefore, after the coating is completed and the soft glue on the outer surface is dried, an embossing jig can be selected to emboss the outer surface. Figure 1 , Figure 3 as well as Figure 4 As shown, by using different embossing jigs, a textured surface 25 can be embossed on the outer surface of the third soft adhesive coating 24 .

[0036] The texture film 20 is produced in small quantities according to the needs of proofing, and the coating thickness is controllable. Since TPU is a good elastomer, the controllability is good when forming embossing, and the embossing shape is ideal. Moreover, during the subsequent coating, the plastic shell can be wrapped with a flat and uniform surface, and the appearance of the sample is ideal. When studying the proofing product, the applicant also considered using leather fabrics from the market to coat the plastic shell. However, using leather fabrics to coat the plastic shell is not ideal. On the one hand, the thickness and softness of the leather fabric are difficult to take into account, while the softness and thickness of the texture film 20 are flexible and controllable. On the other hand, purchasing or customizing leather fabrics with corresponding textures from the market has a long cycle and high cost. Moreover, for the situation where the batch order has not been determined and only individual proofing products are in place, unless the leather fabrics already available on the market are selected, otherwise, the new texture product, by customizing new leather fabrics to meet the proofing product coating requirements of the plastic shell, is obviously inconsistent with the actual production and operation situation.

[0037] The design focus of the present utility model is that it is mainly through multiple coatings on the surface of the cloth substrate 21 to form a first soft glue coating 22, a second soft glue coating 23 and a third soft glue coating 24, which is easy to form a texture surface 25, and a water-based PU glue 30 is coated on the outer plane of the plastic surface shell 10 to form a reliable combination and fixation between the texture film and the plastic surface shell 10, with a good coating effect, so as to realize the rapid and low-cost production of proofing products covered with the texture film 20.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
