Description

Technical Field

[0001] The invention relates to the technical field of acoustic and magnetic anti-theft, and in particular to an acoustic and magnetic anti-theft label, a shell and a manufacturing method thereof. Background Art

[0002] Acoustic-magnetic anti-theft soft tags are one of the most important anti-theft measures for open-shelf sales in the retail industry. Due to their excellent alarm performance and extremely low false alarm rate, they are widely used in retail supermarkets, shopping malls, chain stores and other places around the world. Acoustic-magnetic anti-theft soft tags are usually attached to product packaging or placed in packaging boxes. The products selected by customers are demagnetized at the checkout counter and will not trigger the alarm system at the store entrance. If a thief tries to take the product out of the store, the label on the product will quickly trigger the alarm within the sensing range of the acoustic-magnetic alarm system at the door, achieving the anti-theft effect of reminding store staff and stopping thieves.

[0003] At present, the main acoustic magnetic anti-theft labels (plate labels OR volume labels) on the market are composed of a multi-layer structure including a PS (polystyrene) / PE plastic composite shell, an amorphous resonance sheet, a bias sheet, a PE / PET plastic composite sealing cover, and a self-adhesive paper. Referring to patent documents such as US4510489, US10339776B2, CN201838126U, and CN 102930683A, the existing acoustic magnetic anti-theft labels made of heat-sealed different plastic composite films are difficult to recycle and reuse after being discarded with the outer packaging of the goods, and cannot be naturally degraded by the environment, causing environmental impact.

[0004] Although there are some degradable acoustic magnetic anti-theft labels, such as CN113706810B, an acoustic magnetic anti-theft label with a shell made of PLA degradable plastic, discloses that the label needs to be naturally degraded in a composting environment after being discarded with the outer packaging, and PLA is expensive and easy to degrade during processing, resulting in high processing difficulty, making the label expensive, and consumers need to pay a high price to replace traditional acoustic magnetic anti-theft labels. CN216161189U, an acoustic magnetic anti-theft label with a paper shell, discloses a paper material label, but this type of label will affect the label shell strength and alarm performance after being damp, and has poor stability.

BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Figure 1 This is an exploded view of the acoustic-magnetic anti-theft tag made of wood veneer or bamboo veneer of the present invention.

[0058] Figure 2 The exploded view of the acoustic-magnetic anti-theft tag made of a wooden board or a bamboo board of the present invention.

[0059] Among them: 1-main shell, 2-resonance plate, 3-sealing cover, 4-bias plate, 5-double-sided tape, 6-isolation paper. DETAILED DESCRIPTION

[0060] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0061] like Figure 1-2 As shown, an acoustic magnetic anti-theft tag of a preferred embodiment of the present invention comprises a biasing plate 4 and an acoustic magnetic anti-theft tag shell, wherein the acoustic magnetic anti-theft tag shell comprises a main shell 1 and a sealing cover 3, wherein the main shell 1 is provided with a resonance plate accommodating cavity, and the sealing cover 3 is covered on the main shell 1 and closes the resonance plate accommodating cavity; the main shell 1 and the sealing cover 3 are both made of environmentally friendly materials, preferably wood or bamboo, and the main shell 1 is formed by bending wood veneer, or is formed by machine processing of wood or bamboo boards.

[0062] The resonance sheet accommodating cavity is provided with a plurality of resonance sheets 2; the biasing sheet 4 is fixedly connected to a surface of the sealing cover 3, and the biasing sheet 4 is located outside the shell of the acoustic magnetic anti-theft label. It also includes a double-sided adhesive tape 5, one surface of which is attached to the outer surface of the sealing cover 3, and the other surface of the double-sided adhesive tape 5 is covered with a separation paper 6. When it is needed, the separation paper 6 is torn off and the other side of the double-sided adhesive tape 5 is attached to the corresponding object, which is simple and convenient to operate.

[0063] The acoustic magnetic anti-theft tag based on the above technical features uses wood or bamboo to make the main housing 1 and the sealing cover 3. After the tag is discarded after use, the wood or bamboo can be quickly degraded in the natural environment, avoiding the impact on the environment. At the same time, because wood and bamboo are common materials, they are cheap, and the production only needs to be bent or machined, the production is simple and convenient, which reduces the price of the acoustic magnetic anti-theft tag.

[0064] In this embodiment, the material of the sealing cover 3 and the main shell 1 can be the same or different, but preferably the same. The thickness of the sealing cover 3 is 0.1-0.25 mm, preferably 0.1-0.15 mm, such as 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, etc., or any value or any range between any two values. As for the main shell 1, its thickness is 2-3 mm. When the main shell 1 is made of veneer, the thickness of the veneer is 0.3-0.35 mm, such as 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, etc., or any value or any range between any two values ​​mentioned above. When the main shell 1 is made of a wooden board or a bamboo board, the thickness of the wooden board or the bamboo board is 2 to 3 mm, preferably 2.5 to 3 mm, such as 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, etc., that is, the installation groove can be directly dug out on the wooden board or the bamboo board.

[0065] In this embodiment, the inner bottom of the main shell 1 is provided with reinforcing ribs for supporting the resonance sheet 2. By providing the reinforcing ribs, not only the strength of the acoustic magnetic anti-theft tag itself can be improved, but also the contact area between the inner surface of the main shell 1 and the resonance sheet 2 can be reduced, thereby reducing resonance interference and improving alarm performance. The thickness of the reinforcing ribs needs to be determined according to the depth of the resonance sheet accommodating cavity and the number and thickness of the resonance sheets 2, so as to ensure that after the resonance sheets 2 are installed, the upper surface of the resonance sheet 2 located at the top is flush with the upper end surface of the resonance sheet accommodating cavity, or slightly lower than the upper end surface of the resonance sheet accommodating cavity. Therefore, the thickness of the reinforcing ribs is different for different products. In most cases, the thickness between the bottom wall of the resonance sheet accommodating cavity and the bottom surface of the main shell 1 can be roughly equal to the thickness of the sealing cover 3.

[0066] In this embodiment, the sealing cover 3 and the main shell 1 are bonded by water-based glue, which not only ensures the connection strength between the sealing cover 3 and the main shell 1, but also the water-based glue is easy to degrade. When the label is discarded after use, it can be quickly degraded in the natural environment to avoid impact on the environment.

[0067] At the same time, in order to ensure the bonding strength and sealing performance of the water-based adhesive, a waterproof modifier and a bonding enhancer can be added to the raw materials. Specifically, the raw materials of the water-based adhesive include, by weight: 80-120 parts of polyurethane, 1-3 parts of hydroxyethyl cellulose, 4-8 parts of polyvinyl alcohol, 0.5-1 part of triethylamine, 8-16 parts of natural latex, 4-6 parts of polymethylphenylsiloxane, 1-3 parts of diethylene glycol monobutyl ether, 4-8 parts of waterproof modifier, 1-4 parts of bonding enhancer, 12-24 parts of deionized water, 1-5 parts of preservative, and 0.5-3 parts of defoaming agent.

[0068] The waterproof modifier uses nano titanium dioxide, antimony trioxide and magnetized powder as base materials, and is modified with polyurethane together with a bonding enhancer, effectively improving the waterproof performance and connection strength of the water-based glue, thereby ensuring the connection strength and waterproof sealing between the sealing cover 3 and the main shell 1, improving the durability and reliability of the product, and improving user satisfaction.

[0069] In this embodiment, the width of the resonance plate accommodating cavity corresponds to the width of the resonance plate 2, and the width of the resonance plate 2 is 1.6 to 6.5 mm. The number of the resonance plates 2 is 1 to 7, and when the number of the resonance plates is 2 to 7, the resonance plates are stacked in the resonance plate accommodating cavity. When making the resonance plates, the number and width of the resonance plates 2 need to be considered at the same time to select which of the wood chips, wooden boards or bamboo boards to use. Specifically:

[0070] When the width of the resonance sheet 2 is less than 4 mm, and the number of the resonance sheets 2 is less than or equal to 4, the main housing 1 is made of bamboo sheets or bamboo boards. Because when the width of the resonance sheet 2 is less than 4 mm, and the number of the resonance sheets 2 is less than or equal to 4, if wood is used, the wood cannot resonate with the resonance sheet 2, so it can only be made of bamboo sheets or bamboo boards.

[0071] When the width of the resonance sheet 2 is greater than or equal to 5.5 mm, or when the number of the resonance sheets 2 is greater than 4, the main housing 1 can be made of any one of wood sheets, wooden boards or bamboo boards. When the number of the resonance sheets 2 is sufficient, or the width of the resonance sheets 2 is sufficient, the resonance sheets 2 can achieve resonance with wood or bamboo, so any one of wood sheets, wooden boards or bamboo boards can be selected.

[0072] In addition, the thickness of the resonance sheet is 20 to 40 μm. After the number and thickness of the resonance sheets are determined, the material used by the main shell 1 is also determined accordingly. At the same time, based on the thickness of the main shell 1 being within 2 to 3 mm, a resonance sheet accommodating cavity of a corresponding depth needs to be set to install the resonance sheet 2. Therefore, the thickness between the bottom surface of the main shell 1 and the bottom wall of the resonance sheet accommodating cavity is also relatively determined. In order to ensure the overall strength of the acoustic magnetic anti-theft tag shell, the thickness of the sealing cover 3 needs to correspond to the minimum wall thickness of the main shell 1 (i.e., the thickness between the bottom wall of the resonance sheet accommodating cavity and the bottom surface of the main shell 1). Since the minimum wall thickness of the main shell 1 is related to the depth of the resonance sheet accommodating cavity, and its depth is related to the number of the resonance sheets 2, the thickness of the sealing cover 3 is related to the main shell 1 and the number of the resonance sheets 2. Specifically:

[0073] Assuming the number of the resonance sheets 2 is n, the thickness of the resonance sheets 2 is t, the thickness of the main housing 1 is H1, and the thickness of the sealing cover 3 is H2, the following conditions are satisfied:

[0074] When the main shell 1 and the sealing cover 3 are made of the same material, H2 = (0.05-0.25) (H1-10nt);

[0075] When the material of the main housing 1 is bamboo and the material of the sealing cover 3 is wood, H2=(0.1-0.25)(H1-10nt);

[0076] When the material of the main housing 1 is wood and the material of the sealing cover 3 is bamboo, H2=(0.05-0.2)(H1-10nt);

[0077] At the same time, the above three cases all satisfy that when n≤4, H2≤0.2mm; when n≥5, H2≥0.15mm.

[0078] From the above, it can be seen that when making the acoustic magnetic anti-theft tag shell, first select the corresponding material to make the main shell 1 according to the width of the resonance piece 2, and ensure the thickness of the main shell 1; then according to the thickness of the sealing cover plate 3 of 0.1~0.25mm, and according to the number and thickness of the resonance pieces 2, according to the above relationship, select the material to make the sealing cover 3 and make it satisfy the above relationship.

[0079] It can be seen that the number and width of the resonance plates 2, the material and thickness of the main shell 1, and the material and thickness of the sealing cover 3 are interrelated and influence each other. All factors should be fully considered during production so that each factor meets the above requirements.

[0080] In addition, it should be noted that if veneer is directly used to make the main shell 1, the thickness of the veneer can be the thickness between the bottom wall of the resonance plate accommodating cavity and the bottom surface of the main shell 1. At this time, the thickness between the bottom wall of the resonance plate accommodating cavity and the bottom surface of the main shell 1 may not be equivalent to the thickness of the sealing cover 3. The thickness of the sealing cover plate 3 is directly determined by the relationship between H2 and H1 mentioned above.

[0081] In this embodiment, a wooden board or a bamboo board is used. In actual production, if the four corners of the resonance plate accommodating cavity are right angles, the wood or bamboo may crack or break during machining. Therefore, arcs need to be provided at the four corners of the resonance plate accommodating cavity to avoid cracking or breaking of the wood or bamboo. If the diameter of the arc is D, D may be slightly smaller than half the width of the resonance plate accommodating cavity.

[0082] In summary, the acoustic magnetic anti-theft label of the present invention has a label shell made of natural environmentally friendly materials such as wood or bamboo, and utilizes the better antistatic effect and better mechanical rigidity of wood or bamboo than plastic to improve the performance of the label; utilizes the surface processing characteristics of wood or bamboo, increases the design of reinforcing ribs, improves the strength of the label, and reduces the contact area between the inner surface of the label shell and the resonance plate 2, reduces resonance interference, and improves the alarm performance. After the label is used and discarded, the wood and bamboo can be degraded in the natural environment, meeting the real environmental protection requirements. The appearance is natural color, beautiful and elegant, and is suitable for the anti-theft protection needs of handicrafts, gifts and other commodities.

[0083] In order to solve the above technical problems, the present invention also provides a method for making an acoustic-magnetic anti-theft label, which includes two situations:

[0084] 1. When the main housing 1 is made of wood veneer, the manufacturing method includes the following steps:

[0085] Select wood skin with a thickness of 0.3mm-0.35mm and make it into a roll shape to facilitate continuous production;

[0086] The rolled wood bark is humidified and heated with steam to soften the rolled wood bark. The humidification temperature of the wood bark is room temperature, preferably 20-25°C, and the humidification time needs to be determined according to the dryness of the wood bark, generally 1-10 seconds, to ensure that the humidity of the wood bark after humidification is 40%-60% rh; the temperature of the steam is 70-95°C. After humidification and heating, the wood bark becomes soft and easy to bend.

[0087] The softened rolled wood sheet is cut and bent to prepare a main housing 1 having a resonance sheet accommodating cavity;

[0088] Apply glue on the top edge surface of the main shell 1, and the glue is preferably water-based glue;

[0089] Put a plurality of resonance sheets 2 into the resonance sheet accommodating cavity of the main housing 1;

[0090] The sealing cover 3 is made of wood or bamboo veneer with a thickness of 0.1mm-0.25mm according to the shape of the upper end surface of the main shell 1. The material of the sealing cover 3 is preferably the same as that of the main shell 1;

[0091] Adhere the sealing cover 3 to the main housing 1 to seal the resonance plate accommodating cavity;

[0092] The biasing sheet 4 is fixed to the surface of the sealing cover 3 with double-sided adhesive, and a release paper is attached to the double-sided adhesive. The double-sided adhesive 5 is a double-sided adhesive made of water-based acrylic adhesive.

[0093] 2. When the main housing 1 is made of wood or bamboo, the manufacturing method includes the following steps:

[0094] A wood board or bamboo board with a thickness of 2 to 3 mm is selected and machined to prepare a main housing 1 having a cavity for accommodating a resonance plate;

[0095] Apply glue on the top edge surface of the main shell 1, and the glue is preferably water-based glue;

[0096] Put a plurality of resonance sheets 2 into the resonance sheet accommodating cavity of the main housing 1;

[0097] A wood or bamboo veneer with a thickness of 0.1 to 0.25 mm is selected, and a sealing cover 3 is made according to the shape of the upper end surface of the main shell 1. The material of the sealing cover 3 is preferably the same as that of the main shell 1.

[0098] Adhere the sealing cover 3 to the main housing 1 to seal the resonance plate accommodating cavity;

[0099] The biasing sheet 4 is fixed to the surface of the sealing cover 3 by double-sided adhesive tape, and a release paper is attached to the double-sided adhesive tape 5 .

[0100] In addition, for the above two situations, after the acoustic magnetic anti-theft label is manufactured, its performance needs to be tested. The testing method is as follows:

[0101] In the single-door Ultra-post system, the alarm distances of the acoustic-magnetic anti-theft tag in the three directions of X, Y, and Z are measured and defined as X1, Y1, and Z1 respectively;

[0102] Define the alarm distances of the acoustic and magnetic anti-theft tags with plastic shells as X2, Y2, and Z2 respectively;

[0103] Compare the above alarm distance with the alarm distance of the acoustic magnetic anti-theft tag with a plastic shell, and obtain X1-X2=X0, Y1-Y2=Y0, Z1-Z2=Z0;

[0104] Compare X0, Y0, and Z0 with the threshold S respectively. If X0, Y0, and Z0 are all within the threshold, the system is qualified. If any one of them is not within the threshold, the system is unqualified. The value range of the threshold S is different in different directions. Specifically:

[0105] Corresponding to the X direction of the acoustic magnetic anti-theft tag, that is, corresponding to X0, the threshold is S1, and the value range of S1 is ±10cm, such as ±5cm, ±6cm, ±7cm, ±8cm, ±9cm, etc.;

[0106] Corresponding to the Y direction of the acoustic magnetic anti-theft tag, that is, corresponding to Y0, the threshold is S2, and the value range of S2 is ±5cm, such as ±2cm, ±3cm, ±4cm, etc.;

[0107] Corresponding to the Z direction of the acoustic-magnetic anti-theft tag, that is, corresponding to Z0, the threshold is S3, and the value range of S3 is ±7 cm, such as ±3 cm, ±4 cm, ±5 cm, ±6 cm, etc.

[0108] To illustrate the technical effect of the present application, specific embodiments are listed below to prove:

[0109] Embodiment 1

[0110] The wood veneer with a thickness of about 0.3 to 0.35 mm is selected and made into a roll to facilitate continuous production. The wood roll is humidified, steam heated, and then bent to prepare the shell of the acoustic magnetic anti-theft soft tag with a resonance plate accommodating cavity structure, and water-based glue is applied on the top of the main shell 1 for use.

[0111] Three 6mm resonance sheets 2 are placed in the resonance sheet accommodating cavity of the acoustic magnetic anti-theft label shell, and then a sealing cover 3 is made of 80g of wood veneer with a thickness of 0.1mm to 0.15mm. The main shell 1 and the sealing cover 3 are glued together, and the biasing sheet 4 is fixed to the surface of the sealing cover 3 with a double-sided adhesive 5 of a water-based acrylic adhesive, and then covered with double-sided adhesive 5 and isolation paper 6 to make the label of the present invention ( Figure 1 ). The performance of this tag is compared with that of plastic shell tags with the same resonance plate and bias plate. In a single-door Ultra-post system, the alarm distances in the X, Y, and Z directions are 80-90cm, 30-40cm, and 40-60cm, respectively, which are basically the same as the alarm distances of three 6mm tags with PS / PE and PE / PET sealed shells.

[0112] The above values ​​are verified by H2=(0.05-0.25)(H1-10nt); and when n≤4, H2≤0.2mm, satisfying the above relationship.

[0113] Embodiment 2

[0114] The bamboo skin with a thickness of about 0.25mm to 0.3mm was selected and made into a roll to facilitate continuous production. The bamboo skin roll was humidified, steam heated, and then bent to prepare the shell of the acoustic magnetic anti-theft soft tag with a resonance plate accommodating cavity structure. However, the bamboo skin roll was relatively hard and brittle, and could not be successfully made. This method failed.

[0115] Embodiment 3

[0116] The wood veneer with a thickness of about 0.25mm to 0.3mm is selected and made into a roll to facilitate continuous production. The wood veneer is humidified, steam heated, and then subjected to a hot molding process. The wood veneer is easy to crack and cannot be made into a shell with a resonance plate accommodating cavity structure.

[0117] Embodiment 4

[0118] The bamboo skin with a thickness of about 0.25mm to 0.3mm is selected and made into a roll to facilitate continuous production. The bamboo skin roll is humidified, steam heated, and then subjected to a hot molding process. The bamboo skin roll is easy to crack and cannot be made into a shell with a resonance plate accommodating cavity structure.

[0119] Embodiment 5
