Description

Technical Field

[0001] This application relates to the field of anti-theft tags, and more specifically, to EAS electronic anti-theft tags based on fractal adhesive layer distribution. Background Technology

[0002] Anti-theft tags, belonging to Electronic Article Surveillance (EAS) technology, are used to identify reusable soft anti-theft tags affixed to merchandise or hard anti-theft tags (such as those attached to clothing and footwear) placed at the entrances or checkout lanes of shopping malls and supermarkets. When a tag that has not been handled by a cashier (soft tag not demagnetized or hard tag not removed) passes through the system, the system will sound an alarm to alert staff. Existing EAS anti-theft tags mainly focus on optimizing circuit performance and cost control, such as reducing the thickness of aluminum foil through specific designs without sacrificing performance.

[0003] Currently, when anti-theft tags are illegally removed during use, they do not easily leave obvious marks or damage, thus reducing their anti-theft effectiveness and practicality. Utility Model Content

[0004] To overcome the above shortcomings, this application provides an EAS electronic anti-theft tag based on fractal adhesive layer distribution, which aims to improve the anti-theft tag during use. When the anti-theft tag is illegally removed, it is not easy to leave obvious marks or damage, thereby reducing the anti-theft effect and practicality.

[0005] This application provides an EAS electronic anti-theft tag based on fractal adhesive layer distribution, including a tag structure and a positioning structure. The tag structure includes a tag layer, an isolation layer, a dye layer, and an adhesive layer. The isolation layer is disposed on one side of the tag layer, and the dye layer is disposed on one side of the isolation layer. The adhesive layer is connected to the isolation layer, and the dye layer is disposed within the adhesive layer. The positioning structure includes a positioning frame and a sliding component. The tag layer, the isolation layer, the dye layer, and the adhesive layer are all disposed within the positioning frame, and the sliding component is slidably connected to the positioning frame.

[0006] In one specific implementation, the sliding component includes a sliding plate, connecting paper, and release paper. The sliding plate is slidably connected to the positioning frame. The two sides of the connecting paper are fixedly connected to the sliding plate and the release paper, respectively. The release paper is disposed on one side of the adhesive layer.

[0007] In the above implementation process, the design of the skateboard, connecting paper, and release paper allows for easy removal of the skateboard while simultaneously peeling off the release paper, facilitating label application.

[0008] In one specific implementation, the inner wall of the positioning frame is provided with a placement groove, and the connecting paper is placed in the placement groove.

[0009] In the above implementation process, by placing the connecting paper in the placement slot, it is possible to conveniently provide storage space for the connecting paper and avoid wrinkles or tears during transportation.

[0010] In one specific implementation, two limiting plates are arranged opposite each other on one side of the skateboard, and a limiting groove is opened on one side of the positioning frame, with the limiting plates and the limiting groove being slidably connected.

[0011] In the above implementation process, the movement of the skateboard can be conveniently limited by the sliding connection between the limiting plate and the limiting groove.

[0012] In one specific implementation, an arc-shaped rubber block is fixedly connected to one side of the skateboard, and a slot is provided on one side of the positioning frame, with the arc-shaped rubber block engaging with the slot.

[0013] In the above implementation process, the arc-shaped rubber block engages with the slot, which can easily fix the position of the slide plate and make it easy to pull it out.

[0014] In one specific implementation, a pull block is fixedly connected to one side of the skateboard.

[0015] In the above implementation process, by fixing a pull block to one side of the skateboard, the user can easily pull the skateboard and facilitate the separation of the curved rubber block from the slot.

[0016] In one specific implementation, a through slot is provided at the top of the positioning frame.

[0017] In the above implementation process, by opening a through groove at the top of the positioning frame, it is convenient for users to press the anti-theft label, thereby facilitating the application of the label.

[0018] Compared with existing technologies, the beneficial effects of this application are as follows: The isolation layer isolates the label from the label layer, preserving the label's original electromagnetic properties; the dye layer facilitates the release of dye when the label is peeled off, creating an irreversible mark; the adhesive layer provides strong adhesion, making it difficult to remove. Thus, the EAS anti-theft label not only possesses traditional anti-theft functions but also leaves a mark on the surface of the object when illegally peeled off, providing additional security for goods and enhancing the practicality and security of the EAS anti-theft label. This helps to better protect goods from theft or tampering. Furthermore, the positioning frame facilitates easy positioning of the label, improving the adhesion effect. Attached Figure Description

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Please see Figure 1 This application provides an EAS electronic anti-theft tag based on fractal adhesive layer distribution, including a tag structure 10 and a positioning structure 20.

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The label structure 10 includes a label layer 110, a release layer 120, a dye layer 130, and an adhesive layer 140. The release layer 120 is disposed on one side of the label layer 110, and the dye layer 130 is disposed on one side of the release layer 120. The adhesive layer 140 is connected to the release layer 120, and the dye layer 130 is disposed within the adhesive layer 140. The release layer 120 is made of a transparent material with excellent barrier properties to prevent the dye layer 130 from directly contacting the label layer 110 and causing premature dye leakage. The dye layer 130 contains dye components that are easily released and form a durable mark on the product surface. The adhesive layer 140 is made of a high-viscosity colloid to ensure that the dye layer 130 and the adhesive layer 140 remain firmly attached to the product surface after the label is peeled off.

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The positioning structure 20 includes a positioning frame 210 and a sliding component 220. The label layer 110, the isolation layer 120, the dye layer 130 and the adhesive layer 140 are all disposed within the positioning frame 210, and the sliding component 220 is slidably connected to the positioning frame 210.

[0032] In a specific configuration, the sliding component 220 includes a sliding plate 221, a connecting paper 222, and a release paper 223. The sliding plate 221 is slidably connected to the positioning frame 210. The two sides of the connecting paper 222 are fixedly connected to the sliding plate 221 and the release paper 223, respectively. The release paper 223 is disposed on one side of the adhesive layer 140. The arrangement of the sliding plate 221, the connecting paper 222, and the release paper 223 allows the release paper 223 to be peeled off simultaneously while the sliding plate 221 is being removed, facilitating the attachment of the label.

[0033] In the specific setup, the inner wall of the positioning frame 210 is provided with a placement groove 230, and the connecting paper 222 is placed in the placement groove 230. By placing the connecting paper 222 in the placement groove 230, it is convenient to provide storage space for the connecting paper 222 and avoid the connecting paper 222 from being wrinkled or torn during transportation.

[0034] In the specific setup, two limiting plates 240 are arranged opposite each other on one side of the skateboard 221, and a limiting groove is opened on one side of the positioning frame 210. The limiting plates 240 are slidably connected to the limiting groove. The slidable connection between the limiting plates 240 and the limiting groove can conveniently limit the movement of the skateboard 221.

[0035] In the specific setup, an arc-shaped rubber block 250 is fixedly connected to one side of the skateboard 221, and a slot 260 is provided on one side of the positioning frame 210. The arc-shaped rubber block 250 is engaged with the slot 260. The engagement of the arc-shaped rubber block 250 with the slot 260 facilitates fixing the position of the skateboard 221 and makes it easy to pull it out.

[0036] In the specific setup, a pull block 270 is fixedly connected to one side of the skateboard 221. By fixing the pull block 270 to one side of the skateboard 221, the user can easily pull the skateboard 221, which facilitates the separation of the arc-shaped rubber block 250 from the slot 260.

[0037] In the specific setup, a through groove 280 is provided through the top of the positioning frame 210. By providing a through groove 280 through the top of the positioning frame 210, users can easily press the anti-theft label, thus facilitating the attachment of the label.

[0038] The working principle of the EAS electronic anti-theft tag based on fractal adhesive layer distribution is as follows: When using the EAS electronic anti-theft tag based on fractal adhesive layer distribution, the isolation layer 120 isolates it from the tag layer 110, without affecting the original electromagnetic properties of the tag. The dye layer 130 facilitates the release of dye when the tag is peeled off, creating an irreversible mark. The adhesive layer 140 provides strong adhesion, making it difficult to remove. Therefore, the EAS anti-theft tag not only possesses traditional anti-theft functions but also leaves a mark on the surface of the object when illegally peeled off, providing additional security for the product and enhancing the anti-theft capabilities of EAS. The practicality and security of the anti-theft label help to better protect goods from theft or tampering. When a label needs to be affixed, the overall position of the label is fixed by the positioning frame 210. The user applies a pulling force by pulling the pull block 270 to disengage the arc-shaped rubber block 250 of the slide plate 221 from the slot 260 and release the latch. The slide plate 221 moves along the sliding connection direction between the limiting plate 240 and the limiting slot, and simultaneously drives the connecting paper 222 to pull the release paper 223 off the adhesive layer 140. When the slide plate 221 is completely pulled out, the release paper 223 is completely detached from the adhesive layer. At this time, the label layer 110 is pressed by the through slot 280 to make the adhesive layer adhere to the target object, thus completing the affixing.

[0039] It should be noted that the specific models and specifications of the label layer 110, the isolation layer 120, the dye layer 130, and the adhesive layer 140 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0040] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
