Description

Technical Field

[0001] The utility model belongs to the technical field of radio frequency tags, and particularly relates to a bottomless paper color printing RFID tag. Background Art

[0002] With the continuous expansion of the application of RFID tags, the requirements for cost reduction, reduction of material consumption, and environmental friendliness are getting higher and higher, and the label industry is continuously improving for this goal.

[0003] At present, the bottom paper must exist in conventional RFID tags to protect the label adhesive from being contaminated. However, in actual terminal applications, after the RFID tag is attached to the object to be pasted, the bottom paper loses its value, resulting in waste. Moreover, in the whole industry, especially in the express logistics label industry, when limited by the printer space, the winding diameter of the product cannot be increased, resulting in a limited quantity. The portable printer requires a smaller winding outer diameter, as small as less than 70 mm. The RFID tag with a bottom paper will limit the winding outer diameter. Under the winding diameter of the bottom paper, the carrying quantity of the overall label is limited, and the roll needs to be frequently changed during printing, resulting in low printing efficiency and high costs for winding, transportation, etc.

[0004] Moreover, in some scenarios with personalized printing requirements that need to use color pattern printing, the current labels cannot meet the requirements, and customers still need to print additionally on the label surface, which is relatively complicated and troublesome to operate. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a bottomless paper color printing RFID tag for solving the problems that the label bottom paper causes a small number of labels carried after winding and cannot be color printed.

[0006] The technical solution of the utility model for solving the above technical problems is as follows: A bottomless paper color printing RFID tag, which comprises:

[0007] A color printing composite layer, on the top of which a silicone oil layer is coated. The color printing composite layer includes a thermal sensitive coating and a color printing layer arranged at the bottom of the thermal sensitive coating;

[0008] A substrate layer, arranged at the bottom of the color printing composite layer;

[0009] A chip layer, arranged at the bottom of the substrate layer;

[0010] An adhesive layer, coated at the bottom of the chip layer.

[0011] Compared with the prior art, the above technical solution has the following beneficial effects:

[0012] By setting a color printing layer above the substrate layer, ink printing can be performed, and the required color printing pattern can be displayed on this layer, and the thermal coating above it can print the required content barcode or number, etc. on it by thermal printing. The top silicone oil layer can replace the original base paper. When winding, the silicone oil layer contacts the glue layer at the bottom, which can facilitate and completely tear off the entire label. Removing the base paper reduces costs and increases the number of labels when winding.

[0013] Based on the above technical solution, the embodiment of the present application can also be improved as follows:

[0014] In one embodiment, a thermal printing layer is further disposed on top of the silicone oil layer.

[0015] The beneficial effect of this step is: personalized printing needs can be achieved through the thermal printing layer. After the label is peeled off, the thermal printing layer is set on the silicone oil layer. At this time, the thermal printing layer cooperates with the thermal coating below. When used at the terminal, personalized thermal printing can be achieved using a thermal printer. Moreover, the middle silicone oil layer not only does not affect the printing, but the label has been peeled off and used, and the base paper of the silicone oil layer is no longer needed.

[0016] In one embodiment, a dark icon layer is further included, and the dark icon layer is disposed between the color printing layer and the heat-sensitive coating layer.

[0017] The beneficial effect of this step is that the setting of the dark icon layer can facilitate the needs of some printers that need to identify dark icons to determine the printing position. By adding a dark icon layer, printer recognition is facilitated.

[0018] In one embodiment, the thermal printing layer is a long-lasting thermal printing layer, and the temperature resistance range of the long-lasting thermal printing layer is not less than 80°C.

[0019] The beneficial effect of this step is: at the same time, the temperature range of the heat-sensitive material is selected to be not less than 80°C, so as to avoid the influence of glue coating on the heat-sensitive material.

[0020] In one embodiment, the glue layer is a self-adhesive layer, and the coating temperature of the self-adhesive layer is ≤80°C or ≤100°C.

[0021] The beneficial effect of this step is: the coating temperature is controlled in a lower range for low-temperature coating to avoid affecting heat-sensitive materials.

[0022] In one embodiment, the glue layer is further coated between the chip layer and the substrate layer.

[0023] In one embodiment, the substrate layer is a paper substrate layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will describe in detail the embodiments of the technical solutions of the present utility model in conjunction with the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0029] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which the present utility model belongs.

[0030] In the description of this application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation of the present utility model.

[0031] In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0032] In this application, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0033] As Figure 1 shown, a bottomless paper color printing RFID tag provided by the utility model includes: a color printing composite layer, a substrate layer, a chip layer, and an adhesive layer.

[0034] A silicone oil layer is coated on the top of the color printing composite layer. The color printing composite layer includes a thermal sensitive coating and a color printing layer disposed at the bottom of the thermal sensitive coating. The substrate layer is disposed at the bottom of the color printing composite layer. The color printing layer can be directly bonded and fixed to the substrate layer after UV curing or thermal curing after printing with corresponding color inks. The color printing layer can meet the needs of customers to use color patterns. The chip layer is disposed at the bottom of the substrate layer. The chip layer includes a chip and a printed antenna layer bound to the chip. The adhesive layer is coated on the bottom of the chip layer. The adhesive layer is specifically coated with non-drying adhesive on the bottom layer for contacting the overall surface layer.

[0035] By providing a color printing layer above the substrate layer, ink printing can be performed, and the required color printing pattern can be displayed on this layer. The thermal sensitive coating above it can print out the required content barcodes or numbers, etc. by thermal printing. The silicone oil layer at the top can replace the original bottom paper. When winding, the silicone oil layer contacts the adhesive layer at the bottom. The setting of the silicone oil layer can facilitate the complete tearing off of the entire label, and there is no need to set a bottom paper. After removing the bottom paper, the cost is reduced. Under the same winding diameter, the number of labels during winding can be increased, improving the transportation efficiency.

[0036] In an embodiment, a thermal printing layer is further disposed on the top of the silicone oil layer.

[0037] Through the thermal printing layer, personalized printing requirements can be achieved during terminal use. After uncovering the label, the thermal printing layer is set on the silicone oil layer. At this time, the thermal printing layer cooperates with the thermal sensitive coating below. The thermal sensitive coating is pressed and heated to change color to form the required patterns, numbers, or letters, etc., and personalized thermal printing is realized by using a thermal printer. Moreover, the middle silicone oil layer not only does not affect the printing effect. At this time, the label has been uncovered and used, and the bottom paper function of the silicone oil layer is no longer needed.

[0038] To meet the usage requirements of some printers, it further includes a dark icon layer, which is arranged between the color printing layer and the thermal coating layer. Since some printers need to identify the dark icon to determine the printing position, the setting of the dark icon layer can facilitate these printers. By adding the dark icon layer, it is convenient for the printer to identify.

[0039] In this embodiment, the thermal printing layer is a long-lasting thermal printing layer, and the temperature resistance range of the long-lasting thermal printing layer is not less than 80 °C. To control costs, the adhesive is coated while heating during production. At this time, there is a contradiction between the thermal coating layer and the heating coating. Therefore, the temperature resistance range of the thermal material is selected to be not less than 80 °C to avoid the influence of the glue coating on the thermal material.

[0040] At the same time, the glue layer is an adhesive layer, and the coating temperature of the adhesive is ≤80 °C or ≤100 °C. When the adhesive is coated while heating during simultaneous production, when a long-lasting thermal material with a temperature resistance of not less than 80 degrees Celsius is selected, low-temperature coating is required, and the temperature at which the glue applicator contacts the thermal paper is ≤80 °C or ≤100 °C, which specifically needs to be determined according to the temperature resistance of the thermal material to ensure the effectiveness of the thermal material. By controlling the coating temperature within a lower range for low-temperature coating, the influence on the thermal material is avoided;

[0041] The adhesive layer can select a tape coated outside the line or use a directly purchased tape for lamination, which avoids the influence on the thermal material during gluing.

[0042] In this embodiment, the glue layer is also coated between the chip layer and the substrate layer, that is, both the upper and lower surfaces of the chip layer are coated and wrapped with the glue layer, and then connected to the substrate layer. Among them, the substrate layer is a paper substrate layer.

[0043] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
