Abstract
Description
Technical Field
[0001] The invention relates to the technical field of label production technology, and in particular to a sandwich label production technology.
[0002] The present invention also relates to the technical field of signage, and in particular to a sandwich signage. Background Art
[0003] Split signs are widely used in many fields due to their modular design, easy installation and maintenance. Split signs are easily worn, oxidized and faded due to long-term exposure to air after installation, so their actual service life is short. At the same time, the bending edge of split signs is sharp, and the sharp part is protruding when picking up, which is easy to cause scratches, which is inconvenient.
[0004] The invention patent with Chinese publication number "CN112110001A" discloses a LOGO sign to be installed and its production method and installation device, which improves the installation accuracy and efficiency by covering the surface of the LOGO with hot melt adhesive and transfer film and affixing a protective film on the surface of the hot melt adhesive, and avoids the problem of blockage caused by the viscosity of the double-sided adhesive. At the same time, it plays a certain protective role for the LOGO when it is not installed.
[0005] However, the above LOGO signs have the following defects:
[0006] First, the sign will still be exposed to the air after installation. If the sign is exposed to the air for a long time, it will easily oxidize and fade. In addition, the sign can come into direct contact with other objects, which can easily cause scratches on the sign, affecting the overall structural integrity and visual perception of the sign.
[0007] Second, after the sign is installed, since the sign is made of multiple parts, the installation firmness of each part is different during use. The part with lower adhesion will fall off earlier during use, resulting in the destruction of the overall integrity of the sign;
[0008] Third, the sharp parts of the edge of the sign are not protected or blunted, which can easily cause puncture injuries during use.
[0009] Therefore, it is necessary to make improvements to the above-mentioned defects. Summary of the invention
[0010] The purpose of the present invention is to provide a sandwich sign and a production process thereof to solve the above problems existing in the prior art.
[0011] To achieve the above object, the technical solution adopted by the present invention is: a sandwich label production process, characterized in that it includes the following steps:
[0012] S1: prepare two transparent sheets and a plurality of split labels, wherein the transparent sheets serve as the first plate body and the second plate body;
[0013] S2: placing the split labels at intervals on one side of the first plate;
[0014] S3: preparing an adhesive, and applying the adhesive to the side of the first plate body having the split label attached thereto;
[0015] S4: Laying the second plate body on the side of the first plate body coated with the adhesive, and sandwiching the split sign with the first plate body and the second plate body to form a sandwich sign board;
[0016] S5: The sandwich sign board is formed into a sandwich sign by cutting or punching.
[0017] By adopting the above technical solution: the transparent plate can reduce the impact of the interlayer on the split sign, so that the appearance of the split sign in the interlayer is not affected. At the same time, the split signs placed at intervals allow the first plate body and the second plate body to be cut into specific shapes and sizes according to actual needs. At the same time, interlayer signs can be mass-produced, which greatly improves the production efficiency of the signs.
[0018] The above-mentioned sandwich sign production process can be further configured as follows: in step S1, the first plate body and the second plate body are made of ethylene glycol terephthalate; and a primer is sprayed on the side of the first plate body opposite to the split sign.
[0019] By adopting the above technical solution: the sheet made of ethylene glycol terephthalate has high transparency. PET is the abbreviation of ethylene glycol terephthalate. The sandwich sign made of PET material can significantly improve the visual effect of the sandwich sign, and the split sign is clear and eye-catching in the sandwich. At the same time, PET material has good weather resistance, impact resistance and processing performance, which not only ensures the durability of the sign in a variety of environments, but also facilitates production to meet customer customization needs. In addition, the primer can be used to distinguish the front and back of the sandwich sign, and improve the overall appearance, thereby improving the recognition of the sandwich sign.
[0020] The above-mentioned sandwich sign production process can be further configured as follows: in step S3, the adhesive is UV light-curing glue; in step S4, the sandwich sign board is placed in a light-curing machine to irradiate the sandwich sign board with ultraviolet rays to achieve curing of the UV light-curing glue.
[0021] By adopting the above technical solution: UV light curing glue has the advantages of fast curing speed, excellent bonding performance, good weather resistance, etc. It can resist the erosion of external environmental factors and extend the service life of the sign. The second plate and the first plate use a rubber roller to apply light curing glue to ensure the uniform distribution of the glue layer, avoid bubbles and uneven glue layers, make the sign flatter and smoother, and improve the appearance quality of the product. In addition, the light curing machine can ensure that the UV light curing glue is quickly cured under uniform and efficient lighting conditions, thereby significantly improving the production efficiency and quality stability of the sign. The light curing machine can accurately control the curing time and light intensity, avoid problems such as weak bonding or aging of the glue layer due to incomplete or excessive curing, and enhance the structural stability and durability of the sandwich sign.
[0022] The above-mentioned sandwich label production process can be further configured as follows: step S4 also includes preparing a fixing glue, and sticking the fixing glue to the side of the first plate body to which the split label is attached.
[0023] By adopting the above technical solution: the fixing glue allows the sandwich sign to be quickly bonded to the specified position, thereby realizing the rapid installation of the sandwich sign and improving the convenience of the sandwich sign during the installation process.
[0024] The above-mentioned sandwich sign production process can be further configured as follows: in step S5, a laser cutting machine is used to cut the sandwich sign board.
[0025] By adopting the above technical solutions: the laser cutting machine can achieve high-precision cutting, ensure that the edge of the sandwich sign is flat and smooth, avoid the burrs or dimensional errors that may occur in traditional cutting methods, and at the same time, the laser cutting has a long service life. Laser cutting has the characteristics of non-contact processing, which reduces the pressure on the sandwich sign board and reduces the risk of deformation of the sandwich sign board, thereby ensuring the overall quality and appearance of the sandwich sign. In addition, compared with the method of die punching, the laser cutting machine can adjust the preset cutting pattern to quickly adjust the shape of the sandwich sign.
[0026] The above-mentioned laminated label production process can be further configured as follows: in step S1, a plurality of NFC chips are affixed to the side of the first plate body opposite to the primer at intervals, and the split label covers the side of the first plate body affixed with the NFC chip.
[0027] By adopting the above technical solution: the NFC chip expands the function of the sandwich sign, so that the sandwich sign has the ability of sensing and identification, and can accurately obtain the detailed information carried by the sign. At the same time, the NFC chip is placed on the first plate before the split sign. The NFC chip can provide a positioning point for the split sign, and the split sign can play a certain protective role for the NFC chip and hide it, which will not affect the overall appearance of the sign.
[0028] The above-mentioned laminated sign production process can be further configured as follows: step S5 also includes quality inspection of the laminated sign, and the quality inspection includes smoothness inspection, edge inspection and flatness inspection.
[0029] By adopting the above technical solutions: smoothness detection, edge detection and flatness detection are used to detect the smoothness of the surface and edges of the laminated signs and the flatness of the laminated signs. The product quality of the laminated signs can be controlled more comprehensively, and unqualified laminated signs that do not meet the factory conditions can be effectively identified to ensure that the products meet customer requirements.
[0030] The invention also discloses a sandwich label, which comprises a first plate body, a split label and a second plate body, wherein the split label is attached to one side of the first plate body, and the second plate body is fixedly connected to the first plate body by an adhesive.
[0031] By adopting the above technical solution: the second plate body and the first plate body increase the overall thickness of the product, that is, the color of the split label is protected, the split label will not be exposed to the air, effectively preventing the oxidation of the external color of the split label, and extending the service life of the split label. The edge of the split label is passivated to solve the problem of easy puncture at the edge of the split label, and the sign can better fit the installation depth.
[0032] The sandwich sign can be further configured as follows: a primer is sprayed on the side of the first plate body opposite to the split sign, and a fixing glue is also attached to the primer side of the first plate body.
[0033] By adopting the above technical solution: the primer can be selected according to customer needs, and spraying primers of different colors or patterns can increase the layering of the split signs in the interlayer. In addition, it can improve the overall appearance of the interlayer sign and improve the recognition of the interlayer sign. At the same time, the fixing glue improves the installation speed of the interlayer sign and effectively improves the convenience of fixing the interlayer sign.
[0034] The sandwich label may be further configured as follows: an NFC chip is attached to the side of the first plate away from the primer, and the split label covers the side of the first plate attached to the NFC chip.
[0035] By adopting the above technical solution: the composite design of the sandwich label realizes the functional expansion of the sandwich label. By attaching the NFC chip, it can store and transmit product information, traceability data or personalized content, meet the customized needs of different customers, and bring users a convenient interactive experience. At the same time, the split label covering the top of the NFC chip effectively protects the NFC chip from external physical damage and environmental interference, ensuring its stable operation and extending its service life.
[0036] The beneficial effects of the present invention are:
[0037] First, the first plate body and the second plate body increase the overall thickness of the sandwich sign, which can fully cover the split sign, that is, the color of the split sign is protected, the split sign will not be exposed to the air, effectively preventing the oxidation of the external color of the split sign, extending the service life of the split sign, and passivating the sharp part of the split sign to prevent the sharp part of the split sign from causing damage to the sign installer;
[0038] Second, the sandwich label can be further bonded with the NFC chip during production to expand the function of the sandwich label, and the NFC can provide positioning points for the placement of the split label during production, thereby improving the consistency of the split label during production. The split label can protect the NFC chip from external physical damage and environmental interference, ensuring its stable operation and extending its service life.
[0039] Third, through the composite design of multiple split signs and the second plate body and the first plate body, the sandwich signs can be produced quickly, which improves the production efficiency and provides an effective way for the customization of the signs.
