Description

Technical Field

[0001] The utility model relates to the technical fields of surface pretreatment, rust removal, sandblasting, carving and the like, and in particular to a composite protective rubber template. Background Art

[0002] In the technical fields of surface pretreatment, rust removal, sandblasting, engraving, etc., protective templates for surface pretreatment, rust removal, sandblasting, and engraving protection are often used. These protective templates are usually made of materials such as PVC and polyester. The hardness of the main material is very high and there is no good elasticity, and the protection effect is not good. In order to improve the protection effect of surface pretreatment, rust removal, sandblasting, and engraving, the Chinese patent with patent number CN101691027B proposes a sandblasting protective template, which is a sheet of rubber and has elasticity, so it can absorb the impact of sandblasting. Compared with the prior art, when the template has the same thickness, the sandblasting protective template can accept a larger sandblasting speed requirement, thereby improving the efficiency of sandblasting engraving. At the same time, when the sandblasting speed is fast, the pattern of the sandblasting engraving is clearer. Due to the good elastic effect of the rubber sheet, this type of rubber protective template also achieves good protection effects in surface pretreatment, rust removal, sandblasting, engraving, etc. However, the structure of this type of rubber protective template is a separate sheet of rubber, which is easy to deform during use, and lacks the necessary visual distinction effect, and the recognition is not ideal during use.

[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only an embodiment of a part of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the utility model.

[0030] Embodiment 1

[0031] See also Figure 1-Figure 4 The composite protective rubber template provided in this embodiment is used for the surface to be protected from scratches and wear in surface pretreatment, rust removal, sandblasting or carving processes. The composite protective rubber template includes: a flat rubber sheet 1 and a colored carrier film 2. The flat rubber sheet has a first preset thickness; the colored carrier film is adapted to the size of the flat rubber sheet, connected to the bottom surface of the flat rubber sheet to form a first composite template, and forms a color difference with the flat rubber sheet; when the colored carrier film is fixed to the surface to be protected by a detachable connection, a color difference is formed with the surface to be protected.

[0032] It should be noted that, in this embodiment, the composite protective rubber template can be used for the surface to be protected from scratches and wear during surface pretreatment, rust removal, sandblasting or engraving processes. The composite protective rubber template forms a first composite template through a flat rubber sheet and a colored carrier film. Compared with a simple rubber template, the composite protective rubber template has a more stable structure and is not easily deformed during use. In addition, the colored carrier film forms a color difference with the flat rubber sheet and the surface to be protected, thereby enhancing the recognition of the rubber protective template and facilitating the use of the composite protective rubber template in a specific process.

[0033] In some preferred embodiments, the colored carrier film is detachably connected to the bottom surface of the planar rubber sheet, and the detachable connection method is bonding. The detachable connection method between the colored carrier film and the surface to be protected is bonding. In some preferred embodiments, the composite protective rubber template also includes a first adhesive layer; the first adhesive layer is adapted to the size of the colored carrier film, formed on the planar rubber sheet, and used to bond the bottom surface of the planar rubber sheet to the colored carrier film, thereby enhancing the adhesion of the planar rubber sheet to the colored carrier film. In some other preferred embodiments, the composite protective rubber template also includes a first adhesive layer; the first adhesive layer is adapted to the size of the planar rubber sheet, formed on the colored carrier film, and used to bond the bottom surface of the planar rubber sheet to the colored carrier film, thereby enhancing the adhesion of the planar rubber sheet to the colored carrier film.

[0034] It should be noted that, when the planar rubber sheet 1 is bonded to the colored carrier film 2, the first adhesive layer 4 may be formed on the planar rubber sheet 1, or the first adhesive layer 4 may be formed on the colored carrier film 2. In this embodiment, since the first adhesive layer 4 is adapted to the size of the colored carrier film 2 and formed on the planar rubber sheet 1, or the first adhesive layer 4 is adapted to the size of the planar rubber sheet 1 and formed on the colored carrier film 2, the bottom surface of the planar rubber sheet 1 may be bonded to the colored carrier film 2, thereby enhancing the adhesion of the planar rubber sheet 1 to the colored carrier film 2.

[0035] In some preferred embodiments, the composite protective rubber template further comprises a protective film, the protective film is adapted to the size of the colored carrier film, and is detachably connected to the bottom surface of the colored carrier film to form a second composite template; the protective film is peeled off from the bottom surface of the colored carrier film, and the colored carrier film peeled off is fixed to the surface to be protected. Further, the protective film is detachably connected to the bottom surface of the colored carrier film by bonding. Further, the protective film is made of PET, or the protective film is made of PP, or the protective film is made of PE.

[0036] It should be noted that the protective film 3 is adapted to the size of the colored carrier film 2, and is detachably connected to the bottom surface of the colored carrier film 2 to form a second composite template, so that it can not only avoid the size of the protective film 3 being too large, resulting in material waste, but also avoid the size of the protective film 3 being too small, reducing the protective effect of the protective film 3 on the bottom surface of the colored carrier film 2. It can be understood that the provision of the protective film 3 can reduce the risk of damage to the colored carrier film 2, such as impact or scratching. Once the colored carrier film 2 is damaged, the stability of the overall structure of the colored carrier film 2 will be destroyed, so that the stability of the colored carrier film 2 supporting and fixing the flat rubber sheet 1 is reduced.

[0037] In some preferred embodiments, the colored carrier film includes a second adhesive layer, a colored film layer and a carrier film; the colored film layer is adapted to the size of the carrier film and is formed on the surface of the carrier film; the second adhesive layer is adapted to the size of the colored film layer and is formed on the surface of the colored film layer, and the second adhesive layer is used to bond to the protective film and isolate the colored film layer from the protective film.

[0038] It should be noted that, in this embodiment, since the colored film layer 24 is adapted to the size of the carrier film 25 and is formed on the surface of the carrier film 25, it is possible to avoid material waste while ensuring that the overall visual recognition of the colored carrier film 2 is not affected. In addition, since the second adhesive layer 20 is adapted to the size of the colored film layer 24 and is formed on the surface of the colored film layer 24, it is possible to avoid material waste while achieving strong adhesion and bonding with the protective film. In addition, since the second adhesive layer 20 is located between the protective film and the colored film layer 24, it can be used to isolate the colored film layer 24 from the protective film and protect the colored film layer 24. Further, the colored film layer 24 is a yellow ink layer. In practice, the visual recognition of the yellow ink layer is better. It should also be noted that the carrier film 25 can be prepared by secondary processed PET, PP, PE and other materials to protect the flat rubber sheet 1, the second adhesive layer 20, and the colored film layer 24.

[0039] In some preferred embodiments, the colored carrier film includes a second adhesive layer, a third adhesive layer, a colored film layer and a carrier film; the colored film layer is adapted to the size of the carrier film and is formed on the surface of the carrier film; the second adhesive layer is adapted to the size of the colored film layer and is formed on the surface of the colored film layer; the third adhesive layer is adapted to the size of the second adhesive layer and is formed on the surface of the second adhesive layer; the third adhesive layer is bonded to the protective film; the second adhesive layer isolates the colored film layer from the third adhesive layer, and forms a composite adhesive layer with the third adhesive layer to improve the strength of the colored film layer.

[0040] It should be noted that, in this embodiment, since the colored film layer 24 is adapted to the size of the carrier film 25 and is formed on the surface of the carrier film 25, it is possible to avoid material waste while ensuring that the overall visual recognition of the colored carrier film 2 is not affected. In addition, since the second adhesive layer 20 is adapted to the size of the colored film layer 24 and is formed on the surface of the colored film layer 24, it is possible to avoid material waste while achieving strong adhesion and bonding with the protective film. In addition, since the third adhesive layer 23 is bonded to the protective film, the second adhesive layer 20 isolates the colored film layer 24 from the third adhesive layer 23, and forms a composite adhesive layer with the third adhesive layer 23, thereby increasing the distance between the colored film layer 24 and the protective film, increasing the thickness and strength of the adhesive layer, and improving the strength of the colored film layer 24. At the same time, the second adhesive layer 20 is located between the third adhesive layer 23 and the colored film layer 24, so the adhesion between the third adhesive layer 23 and the colored film layer 24 can be increased. It should also be noted that the carrier film 25 can be made of secondary processed PET, PP, PE and other materials to protect the flat rubber sheet 1, the second adhesive layer 20, the third adhesive layer 23 and the colored film layer 24. Preferably, the colored film layer can be a colored ink layer. For example, the colored film layer is a yellow ink layer.

[0041] Embodiment 2

[0042] When the composite protective rubber template is applied to the engraving process to protect the surface to be protected, the surface to be protected is a plane body to be engraved.

[0043] See also Figure 1-Figure 4 This embodiment provides a composite protective rubber template, including:

[0044] A flat rubber sheet 1, wherein the surface of the flat rubber sheet 1 is processed by a first engraving process to form a hollow pattern or text;

[0045] The colored carrier film 2 is adapted to the size of the flat rubber sheet 1, connected to the bottom surface of the flat rubber sheet 1 to form a first composite template, and forms a color difference with the flat rubber sheet 1; the flat rubber sheet 1 is fixed on the colored carrier film 2 when undergoing the first engraving process, and the engraving depth is maintained above the upper surface of the colored carrier film 2; the colored carrier film 2 is fixed on the plane body to be engraved by a detachable connection and undergoes the second engraving process, and the color of the colored carrier film 2 and the plane body to be engraved form a color difference; the second engraving process uses the hollow pattern or text as the engraving path, penetrates the colored carrier film 2, and forms a pattern or text consistent with the hollow pattern or text on the plane body to be engraved.

[0046] It should be noted that, in this embodiment, the surface of the planar rubber sheet 1 is pierced by a first engraving process to form a hollow pattern or text. The first engraving process can be a computer engraving process or a manual engraving process. It is understandable that both the computer engraving process and the manual engraving process belong to the existing engraving process, and this embodiment will not be described in detail. When the surface of the planar rubber sheet 1 is pierced by the first engraving process, whether it is a computer engraving process or a manual engraving process, due to the elasticity of the planar rubber sheet 1, if the planar rubber sheet 1 is not attached and fixed, the planar rubber sheet 1 will produce a certain degree of deformation, causing the hollow pattern or text to be formed to be deformed, thereby reducing the engraving process. In this embodiment, a colored carrier film 2 is provided on the bottom surface of the flat rubber sheet 1, the colored carrier film 2 is adapted to the size of the flat rubber sheet 1, and is connected to the bottom surface of the flat rubber sheet 1 to form a first composite template, and forms a color difference with the flat rubber sheet 1. The flat rubber sheet 1 is fixed on the colored carrier film 2 when undergoing the first engraving process, and the engraving depth is maintained above the upper surface of the colored carrier film 2. Therefore, when the first engraving process occurs, the colored carrier film 2 firmly attaches and fixes the flat rubber sheet 1. At the same time, the colored carrier film 25 forms a color difference with the flat rubber sheet 1. Therefore, it can not only avoid deformation of the flat rubber sheet 1 during engraving, but also improve the visual recognition during engraving, so that the hollow pattern or text is accurately formed on the flat rubber sheet 1. In addition, when the colored carrier film 2 is fixed on the plane body to be engraved by a detachable connection, it is subjected to a second engraving process. The colored carrier film 2 forms a color difference with the color of the plane body to be engraved. The second engraving process uses the hollow pattern or text as the engraving path, penetrates the colored carrier film 2, and forms a pattern or text consistent with the hollow pattern or text on the plane body to be engraved. Therefore, when the second engraving process occurs, the colored carrier film 2 firmly attaches and fixes the flat rubber sheet 1 on the plane body to be engraved. At the same time, the color carrier film 25 forms a color difference with the plane body to be engraved, so that not only can the deformation of the flat rubber sheet 1 be avoided during engraving, but also the visual recognition during engraving can be improved, so that a pattern or text consistent with the hollow pattern or text is formed on the plane body to be engraved, thereby improving the engraving accuracy. It should be noted that the colored carrier film 2 forms a color difference with the flat rubber sheet 1 and the color of the plane body to be engraved. When engraving, whether it is through manual visual recognition or machine visual recognition, the existence of color difference can provide significant visual recognition for engraving, thereby improving engraving accuracy.

[0047] It should also be noted that, in this embodiment, the flat rubber sheet 1 is fixed on the colored carrier film 2 when undergoing the first engraving process, and the engraving depth is maintained above the upper surface of the colored carrier film 2, thereby avoiding piercing the upper surface of the colored carrier film 2. It should be noted that if the upper surface of the colored carrier film 2 is pierced during the first engraving process, the stability of the overall structure of the colored carrier film 2 will be destroyed, so that the stability of the colored carrier film 2 supporting and fixing the flat rubber sheet 1 is reduced, thereby causing the flat rubber sheet 1 to be deformed when the first engraving process and the second engraving process occur, resulting in reduced engraving accuracy.

[0048] It should also be noted that, in the present embodiment, the colored carrier film 2 is adapted to the size of the planar rubber sheet 1 and is connected to the bottom surface of the planar rubber sheet 1 to form a first composite template, thereby not only avoiding the waste of materials caused by the colored carrier film 2 being too large, but also avoiding the colored carrier film 2 being too small, thereby reducing the adhesion and support effect on the planar rubber sheet 1.

[0049] It should be noted that the second engraving process is a sandblasting engraving process. The sandblasting engraving process is a prior art and will not be described in detail in this embodiment. In addition, the planar rubber sheet 1 can strongly protect the protected object from external impact, collision, and damage.

[0050] In some preferred embodiments, the colored carrier film 2 is detachably connected to the bottom surface of the planar rubber sheet 1 by bonding. The colored carrier film 2 is detachably connected to the planar body to be engraved by bonding.

[0051] In some preferred embodiments, the composite protective rubber template further includes a protective film 3, the protective film 3 is adapted to the size of the colored carrier film 2, and is detachably connected to the bottom surface of the colored carrier film 2 to form a second composite template; before the second engraving process is implemented, the protective film 3 is peeled off from the bottom surface of the colored carrier film 2, and the colored carrier film 2 peeled off from the protective film 3 is fixed to the plane body to be engraved. The protective film 3 is detachably connected to the bottom surface of the colored carrier film 2 by bonding. Further, the protective film 3 can be made of PET, PP, or PE.

[0052] It should be noted that the protective film 3 is adapted to the size of the colored carrier film 2, and is detachably connected to the bottom surface of the colored carrier film 2 to form a second composite template, so that it can not only avoid the size of the protective film 3 being too large, resulting in material waste, but also avoid the size of the protective film 3 being too small, reducing the protective effect of the protective film 3 on the bottom surface of the colored carrier film 2. It can be understood that the provision of the protective film 3 can reduce the risk of damage to the colored carrier film 2, such as being hit or scratched. Once the colored carrier film 2 is damaged, the stability of the overall structure of the colored carrier film 2 will be destroyed, so that the stability of the colored carrier film 2 supporting and fixing the flat rubber sheet 1 is reduced, thereby causing the flat rubber sheet 1 to be deformed when the first engraving process and the second engraving process occur, resulting in reduced engraving accuracy.

[0053] In some preferred embodiments, the composite protective rubber template further includes a first adhesive layer 4; the first adhesive layer 4 is adapted to the size of the colored carrier film 2, formed on the planar rubber sheet 1, and used to bond the bottom surface of the planar rubber sheet 1 to the colored carrier film 2, thereby enhancing the adhesion of the planar rubber sheet 1 to the colored carrier film 2. Alternatively, the composite protective rubber template further includes a first adhesive layer 4; the first adhesive layer 4 is adapted to the size of the planar rubber sheet 1, formed on the colored carrier film 2, and used to bond the bottom surface of the planar rubber sheet 1 to the colored carrier film 2, thereby enhancing the adhesion of the planar rubber sheet 1 to the colored carrier film 2.

[0054] It should be noted that, when the planar rubber sheet 1 is bonded to the colored carrier film 2, the first adhesive layer 4 may be formed on the planar rubber sheet 1, or the first adhesive layer 4 may be formed on the colored carrier film 2. In this embodiment, since the first adhesive layer 4 is adapted to the size of the colored carrier film 2 and formed on the planar rubber sheet 1, or the first adhesive layer 4 is adapted to the size of the planar rubber sheet 1 and formed on the colored carrier film 2, the bottom surface of the planar rubber sheet 1 may be bonded to the colored carrier film 2, thereby enhancing the adhesion of the planar rubber sheet 1 to the colored carrier film 2.

[0055] In some further preferred embodiments, the colored carrier film 2 includes a second adhesive layer 20, a colored film layer 24 and a carrier film 25; the colored film layer 24 is adapted to the size of the carrier film 25 and is formed on the surface of the carrier film 25; the second adhesive layer 20 is adapted to the size of the colored film layer 24 and is formed on the surface of the colored film layer 24, and the second adhesive layer 20 is used to bond to the protective film and isolate the colored film layer 24 from the protective film.

[0056] It should be noted that, in this embodiment, since the colored film layer 24 is adapted to the size of the carrier film 25 and is formed on the surface of the carrier film 25, it is possible to avoid material waste while ensuring that the overall visual recognition of the colored carrier film 2 is not affected. In addition, since the second adhesive layer 20 is adapted to the size of the colored film layer 24 and is formed on the surface of the colored film layer 24, it is possible to avoid material waste while achieving strong adhesion and bonding with the protective film. In addition, since the second adhesive layer 20 is located between the protective film and the colored film layer 24, it can be used to isolate the colored film layer 24 from the protective film and protect the colored film layer 24. Further, the colored film layer 24 is a yellow ink layer. In practice, the visual recognition of the yellow ink layer is better. It should also be noted that the carrier film 25 can be prepared from secondary processed PET, PP, PE and other materials to protect the flat rubber sheet 1, the second adhesive layer 20, the colored film layer 24, and to carry and position the split piece of the flat rubber sheet 1 during engraving.

[0057] In some other preferred embodiments, the colored carrier film 2 includes a second adhesive layer 20, a third adhesive layer 23, a colored film layer 24 and a carrier film 25; the colored film layer 24 is adapted to the size of the carrier film 25 and is formed on the surface of the carrier film 25; the second adhesive layer 20 is adapted to the size of the colored film layer 24 and is formed on the surface of the colored film layer 24; the third adhesive layer 23 is adapted to the size of the second adhesive layer 20 and is formed on the surface of the second adhesive layer 20; the third adhesive layer 23 is bonded to the protective film; the second adhesive layer 20 isolates the colored film layer 24 from the third adhesive layer 23, and forms a composite adhesive layer with the third adhesive layer 23 to improve the strength of the colored film layer 24.

[0058] It should be noted that, in this embodiment, since the colored film layer 24 is adapted to the size of the carrier film 25 and is formed on the surface of the carrier film 25, it is possible to avoid material waste while ensuring that the overall visual recognition of the colored carrier film 2 is not affected. In addition, since the second adhesive layer 20 is adapted to the size of the colored film layer 24 and is formed on the surface of the colored film layer 24, it is possible to avoid material waste while achieving strong adhesion and bonding with the protective film. In addition, since the third adhesive layer 23 is bonded to the protective film, the second adhesive layer 20 isolates the colored film layer 24 from the third adhesive layer 23, and forms a composite adhesive layer with the third adhesive layer 23, thereby increasing the distance between the colored film layer 24 and the protective film, increasing the thickness and strength of the adhesive layer, and improving the strength of the colored film layer 24. At the same time, the second adhesive layer 20 is located between the third adhesive layer 23 and the colored film layer 24, so the adhesion between the third adhesive layer 23 and the colored film layer 24 can be increased. It should also be noted that the carrier film 25 can be made of secondary processed PET, PP, PE and other materials, and is used to protect the flat rubber sheet 1, the second adhesive layer 20, the third adhesive layer 23, and the colored film layer 24, and to carry and position the split pieces of the flat rubber sheet 1 during engraving. Preferably, the colored film layer can be a colored ink layer. For example, the colored film layer is a yellow ink layer.
