Description
Technical Field
[0001] The utility model relates to the technical field of knife rollers, and particularly relates to a die-cutting knife roller for a film-coated RFID tag. Background Art
[0002] An RFID tag, also known as an electronic tag, is a communication technology that identifies specific targets through radio signals and reads and writes relevant data. It has the advantages of high-speed identification, resistance to harsh environments, and strong confidentiality. Therefore, it has been widely used in many fields such as logistics, warehousing management, medical care and identity recognition, food processing, and real-time monitoring of production data and quality tracking in the industrial manufacturing process.
[0003] A film-coated RFID tag is to protect the RFID tag through a film-coating process to enhance its durability, waterproofness, stain resistance, and aesthetics. The film-coating material can be a transparent or semi-transparent plastic film such as PET or PVC, so that it can closely adhere to the surface of the RFID tag to form a protective layer.
[0004] At present, the existing film-coated RFID tags are produced by die-cutting. The die-cutting equipment is a rotary die-cutting machine, which includes a die-cutting knife roller and a pressure-bearing roller that cooperate with each other up and down. It has the advantages of high efficiency and stability and is suitable for mass production. The die-cutting process is as follows: the die-cutting knife roller die-cuts the composite substrate according to the shape of the finished product. Specifically, it cuts through the film-coating layer, the first adhesive layer, Dry inaly, and the second adhesive layer, but retains the bottom substrate layer. Accordingly, a finished product area and a waste area are formed on the substrate layer.
[0005] However, as Figure 6 shown, when the forming blade on the die-cutting knife roller in the prior art die-cuts the composite substrate, due to the relatively large inner angle of its blade edge, it will strongly squeeze the film-coating layer in the finished product area, resulting in obvious deformation at the edge of the finished product area and reducing the quality of the finished product. In addition, it also makes the contact area between the inner blade surface of the forming blade and the adhesive layer larger, resulting in the adhesive being easily squeezed and remaining on the cutting surfaces of the film-coating layer and Dry inaly in the finished product area. When the finished product is wound up, it will contaminate the surface of the film-coated RFID tag, ultimately reducing the appearance cleanliness. Summary of the Utility Model
[0006] The purpose of the utility model is to provide a die-cutting knife roller for a film-coated RFID tag, which solves the technical problem of poor die-cutting effect of the die-cutting knife roller for the existing film-coated RFID tag.

[0047] Embodiment:
[0048] As Figures 1 to 5 shown, an embodiment of the present application discloses a die-cutting cutter roller for laminated RFID tags, which is used for die-cutting and producing laminated RFID tags. Its specific structure includes: a roller body 1 and a die 2.
[0049] The roller body 1 has a cylindrical structure and is used to connect and support other components.
[0050] The die 2 has a cylindrical structure and is sleeved on the roller body 1. And as Figure 2 shown, it has a number of die-cutting units arranged at intervals along the axial direction. In this embodiment, it is set to two, but not limited thereto. It can also be one, three or more, and is adjusted according to the actual working conditions without specific limitation.
[0051] Specifically, as Figure 2 shown, each die-cutting unit includes a plurality of forming blades 21 evenly distributed in a circumferential manner on the outer peripheral surface of the die 2; the forming blades 21 are integrally formed with the die 2.
[0052] Among them, the forming blade 21 has an annular structure and is used for die-cutting finished products. And as Figure 3 and Figure 4 shown, it includes a blade edge 211 and a blade body 212; among them, the inner angle 211a of the blade edge 211 is 0° to 10°, the outer angle 211b of the blade edge 211 is 0° to 40°, and the sum of the inner angle 211a and the outer angle 211b is 30° to 50°.
[0053] It should be noted that the inner angle 211a refers to the inclination angle of the cutting edge 211 on the side close to the finished product area, and the outer angle 211b refers to the inclination angle of the cutting edge 211 on the side close to the waste material area.
[0054] It can be understood that by defining the inner angle 211a of the cutting edge 211, the extrusion on the film coating layer in the finished product area during die cutting is reduced, thus avoiding obvious deformation at the edge of the finished product area, ensuring the quality of the finished product, and also reducing the contact area between the forming blade 21 and the adhesive layer. In this way, it is avoided that the adhesive remains on the film coating layer in the finished product area and the cutting surface of the Dry inaly, and further, when the finished product is wound up, it is avoided that it will contaminate the surface of the film RFID label, thereby improving the appearance cleanliness.
[0055] It can be understood that by defining the outer angle 211b of the cutting edge 211, the sharpness of the cutting edge 211 is ensured, thus ensuring the die cutting effect, avoiding the generation of burrs, tearing or unevenness during the cutting process, and improving the cutting efficiency.
[0056] It can be understood that by defining the sum of the inner angle 211a and the outer angle 211b, the structural strength of the forming blade 21 is ensured, avoiding situations such as chipping or breakage, improving the durability and cutting stability, and also improving the cutting accuracy and effect.
[0057] In this application, by defining the inner angle 211a of the cutting edge 211, obvious deformation at the edge of the finished product area is avoided, the quality of the finished product is ensured, the contact area between the forming blade 21 and the adhesive layer is reduced, and the appearance cleanliness of the finished product is improved. Then, by defining the outer angle 211b, the sharpness is improved and the die cutting effect is ensured. Finally, by defining the sum of the inner angle 211a and the outer angle 211b, the structural strength of the forming blade 21 is ensured, avoiding situations such as chipping or breakage.
[0058] In some embodiments, the inner angle 211a of the cutting edge 211 is 2° - 8°, and the outer angle 211b of the cutting edge 211 is 15° - 30°.
[0059] Exemplarily, the inner angle 211a of the cutting edge 211 is 5°, and the outer angle 211b of the cutting edge 211 is 25°.
[0060] In some embodiments, the blade height of the forming blade 21 is 1.5 mm - 1.9 mm, and the blade width of the forming blade 21 is 0.02 mm - 0.03 mm.
[0061] Exemplarily, the blade height of the forming blade 21 is 1.7 mm, and the blade width of the forming blade 21 is 0.02 mm.

[0064] In some embodiments, as Figure 2 shown, the die-cutting shape of the forming blade 21 is rectangular, and the corners have arc transitions. This can improve the cutting stability, reduce the resistance and wear of the tool during cutting, thereby improving the cutting efficiency, and also helps to reduce the material deformation and fracture phenomena during cutting, further improving the cutting quality; however, it is not limited thereto, and it can also be circular, elliptical or other shapes, which are adjusted according to the actual application situation and are not specifically limited.
[0065] In some embodiments, it further includes: two roller pillows 3, which are in a cylindrical structure and are respectively sleeved on both ends of the roller body 1, and have the same diameter as the die cutter 2.
[0066] By providing the roller pillows 3, the roller body 1 can be supported, ensuring the stability and balance of the roller body 1 during high-speed operation, and the distance between the upper and lower rollers can be guaranteed to adapt to the die-cutting materials of corresponding thicknesses.
[0067] In some embodiments, it further includes: two support shafts 4, which are respectively coaxially arranged at both ends of the roller body 1 and correspond to the insertion slots on the clamping mechanism, for supporting the film-coated RFID tag die-cutting roller and facilitating disassembly and assembly.
[0068] In some embodiments, it further includes: a driving gear 5, which is sleeved on one support shaft 4 and is fixedly connected to the end face of the roller body 1, and meshes with the gear at the corresponding position on the pressure roller, thereby realizing the synchronous rolling in opposite directions of the die-cutting roller and the pressure roller, improving the die-cutting stability.
