[0003] The working principle of existing barcode printers is mainly based on two technologies: thermal printing and thermal transfer printing. When preparing to print a barcode, the barcode data is first transmitted to the barcode printer through a computer or other device. After the printer's processor receives this data, it will convert it into specific printing instructions. In thermal printing, the print head heats the special thermal paper to change its chemical coating color, thereby revealing the barcode, text or pattern. In thermal transfer printing, the print head heats the carbon ribbon to melt the ink on the carbon ribbon and transfer it to the label material to form a permanent barcode. The sensor monitors the position and status of the printing paper in real time to ensure that the barcode can be printed completely.

[0004] Although the existing barcode printers with RFID functions are powerful, their high cost makes it difficult for small and medium-sized enterprises to afford them, limiting their market penetration. Secondly, RFID technology is relatively complex, which places high demands on the research and development and manufacturing of equipment, increasing the difficulty of technical implementation. In addition, this type of printer is more picky about the operating environment.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1: Figures 1 to 6As shown, an RFID barcode printer capable of resisting metal interference according to an embodiment of the present invention comprises a body 1, a switch 2 is arranged on one side of the body 1, a heat pressing device 3 is rotatably arranged on the upper surface of the body 1, the heat pressing device 3 is a print head of a thermal transfer printer in the prior art, a paper outlet 13 is opened on one side of the body 1, a label tape 15 is placed on the paper outlet 13, and a printed label paper 16 is arranged on the label tape 15, an upper cover 113 is rotatably arranged on the upper part of the body 1, and two positioning blocks 112 are elastically arranged on one side of the upper cover 113, and the lower surface of each positioning block 112 is fixed A hook block 111 is connected, and the two hook blocks 111 can be snapped with the machine body 1 to complete the buckling of the upper machine cover 113 and the machine body 1, which can facilitate the replacement of the label belt 15. A driving component is rotatably arranged inside the machine body 1, and the driving component is used to drive the movement of the label belt 15. The driving component includes a rotating roller 18 rotatably arranged on the machine body 1, and the circumferential surface of the rotating roller 18 is provided with friction stripes, and the friction stripes are used to increase the friction force with the label belt 15; a limiting component 11 is arranged inside the machine body 1, and the limiting component 11 is used to limit and smooth the label belt 15, which can prevent the wrinkles of the label belt 15; In a thermal transfer printer, the print head is the most core component. It is composed of many tiny electronic components, which can quickly and accurately control the heating and cooling of each component, realize high-speed ink transfer, and enable delicate, high-definition patterns and texts to be presented. The carbon ribbon is usually composed of a substrate, an ink layer and a protective layer. The ink layer contains special ink. When heated by the print head, the ink will melt and transfer to the printing medium.

[0023] Specifically, although the existing barcode printers are powerful, their high cost makes it difficult for small and medium-sized enterprises to afford them, limiting their market penetration. Secondly, RFID technology is relatively complex, which places high demands on the research and development and manufacturing of equipment, increasing the difficulty of technical implementation. In addition, this type of printer is more picky about the use environment. It not only requires a stable power supply, but also needs to be used with specific reading and writing equipment, which undoubtedly narrows its potential application scope. In summary, cost, technical difficulty and environmental adaptability are the main obstacles to the popularization of RFID barcode printers. Therefore, the present invention solves this problem by setting a certain structure. First, the printer is started by the switch 2. Then, the rotating roller 18 in the driving component starts to rotate in the machine body 1. The friction stripes on its surface effectively increase the friction between it and the label tape 15, ensuring that the label tape 15 can move stably and smoothly. At the same time, the print head accurately controls the heating and cooling of each tiny electronic component according to the preset pattern and text information, so that the ink on the carbon tape melts after being heated and is accurately transferred to the label paper 16. During the printing process, the limiting component 11 plays a key role. It not only limits the label tape 15 to prevent it from deflecting, but also effectively avoids the wrinkle problem of the label tape 15 by smoothing it, ensuring the stability of the printing quality. The thermal transfer printer achieves high-speed and accurate printing effects by virtue of its precise hot pressing device 3 and efficient driving component. At the same time, the upper cover 113 can be buckled and separated from the machine body 1 through simple operations, so that a new label tape 15 can be replaced conveniently and quickly. Through advanced thermal transfer technology, high adhesion and durability of labels on various materials are ensured. This unique printing technology not only improves production efficiency, but also enhances the stability of labels in different environments; It solves the problems of high cost, difficult technical barriers and poor adaptability of existing barcode printing technologies.

[0024] like Figure 1 As shown, the driving assembly of this embodiment includes a built-in motor arranged inside the body 1, the output end of the built-in motor is fixedly connected to a driving gear 17, one side of the driving gear 17 is fixedly connected to a rotating roller 18, and a label belt 15 is arranged on the circumferential surface of the rotating roller 18.

[0025] Specifically, the power is provided by the built-in motor, and the output end of the motor drives the fixed driving gear 17 to rotate, which in turn drives the rotating roller 18 to rotate, and the label tape 15 on the circumferential surface of the rotating roller 18 moves accordingly to realize the printing process. This design simplifies the transmission structure, improves the transmission efficiency, ensures the smooth and continuous transportation of the label tape 15, is conducive to improving the printing quality and efficiency, while reducing energy consumption and noise, and enhancing the stability and durability of the printer.

[0026] like Figure 1 As shown, the driving component of this embodiment drives the rotating roller 18 to rotate during the rotation of the thermal transfer printer. The rotation of the rotating roller 18 assists the hot pressing of the hot pressing device 3 and drives the label tape 15 to move toward the paper outlet 13 to complete the printing work.

[0027] Specifically, the driving assembly drives the rotating roller 18 to rotate. The rotating roller 18 not only assists the heat pressing device 3 to apply uniform heat pressure to the printing material to ensure clear printing of the image, but also undertakes the important task of transmitting the label belt 15 to enable it to move smoothly and continuously toward the paper outlet 13. This design not only improves the printing efficiency, but also ensures the stability of the printing quality, realizes efficient and accurate printing operations, and greatly improves the practicality of the thermal transfer printer.

[0028] like Figure 1 As shown, the limiting assembly 11 of this embodiment includes a limiting column 19 fixedly connected to the inside of the body 1, the limiting column 19 is a rectangular parallelepiped, and a long cleaning plate 114 fixedly connected to one side thereof, the cleaning plate 114 can clean the surface of the label tape 15 before printing, and remove dust and oil stains that may be attached to the surface of the label tape 15. A positioning plate 31 is fixedly connected to the body 1, and the positioning plate 31 is used to limit the label tape 15 when the label tape 15 is output.

[0029] Specifically, it is achieved through the cooperation between the limiting column 19 fixed inside the body 1 and the long cleaning plate 114, as well as the auxiliary role of the positioning plate 31. Before printing, the long cleaning plate 114 uses its structural advantage of being fixed with the limiting column 19 to clean the surface of the passing label tape 15, effectively remove dust and oil stains, and ensure the printing quality. At the same time, the positioning plate 31 limits the label tape 15 when the label tape 15 is output, ensuring that the label tape 15 moves stably along the predetermined path to avoid dislocation or deviation. This design not only improves the printing clarity, but also enhances the stability and reliability of the equipment, providing a strong guarantee for high-quality printing.

[0030] Embodiment 2: Figures 1 to 6 As shown, compared with Example 1, another implementation of the present invention is: the limiting component 11 also includes two spring pieces 110 fixedly connected to the inner wall of the body 1, and the two spring pieces 110 are used to press the label tape 15. The two spring pieces 110 press the two sides of the label, which can straighten the position where the label tape 15 may be deflected during the transmission and printing process, and at the same time limit the longitudinal deviation of the label tape 15.

[0031] Specifically, the limit component 11 further optimizes the transmission and printing effects of the label tape 15 by adding two spring pieces 110 fixed to the inner wall of the body 1. During the transmission of the label tape 15, the two spring pieces 110 exert moderate pressure on both sides of the label tape 15, which can not only effectively smooth out the deflection that may be caused by external force or uneven internal tension, but also ensure the stable transmission of the label tape 15 in the longitudinal direction and avoid the occurrence of offset. This design significantly improves the printing accuracy and the smoothness of the transmission of the label tape 15, laying a solid foundation for high-quality and efficient printing operations, and also prolongs the service life of the printing equipment and the label tape 15.

[0032] like Figure 4 and Figure 5 As shown, an auxiliary plate 12 is fixedly connected to one side of the body 1 of this embodiment, and a limiting plate 14 is fixedly connected to the upper surface of the auxiliary plate 12. A paper outlet 13 is formed between the auxiliary plate 12 and the limiting plate 14, which can limit the printed label paper 16 to prevent curling due to heating after printing.

[0033] Specifically, the auxiliary plate 12 fixed on one side of the body 1 is cleverly combined with the limiting plate 14 to form a paper outlet 13. This design plays a key role in the thermal transfer printing process. The space formed between the auxiliary plate 12 and the limiting plate 14 effectively limits the printed label paper 16, effectively preventing the label paper 16 from curling due to thermal expansion and contraction after heated printing, which not only improves the flatness and aesthetics of the printed product, but also ensures the smoothness and stability of the label paper 16 during the paper output process.

[0034] like Figure 4 and Figure 5 As shown, a partition 41 is fixedly connected inside the body 1 of this embodiment, and a switching module 45 is fixedly connected to one side of the partition 41. The switching module 45 is used for signal and data conversion.

[0035] Specifically, the partition 41 fixed inside the body 1 carries the adapter module 45, which is responsible for the conversion of signals and data. This design ensures efficient and stable data transmission and improves the operating efficiency of the equipment.

[0036] like Figure 5 As shown, in this embodiment, a protective cover 4 is fixedly connected to the surface of the adapter module 45, and the protective cover 4 is used to protect the adapter module 45. A plurality of fixing columns 48 are fixedly connected to the surface of the partition 41, wherein the chip modules 44 are fixedly connected to a plurality of fixing columns 48, and another plurality of fixing columns 48 are used to fix the adapter module 45.

[0037] Specifically, the protective cover 4 fixed to the surface of the adapter module 45 effectively protects the potential damage of the external environment to the adapter module 45, thereby improving the durability and safety of the equipment. At the same time, the fixing column 48 on the partition 41 not only firmly supports the chip module 44, but also undertakes the task of fixing the adapter module 45, thereby ensuring the stability and efficiency of data transmission. This design optimizes the internal layout and enhances the overall performance and reliability of the equipment.

[0038] like Figure 6 As shown, one side of the partition 41 of this embodiment is threadedly connected with a plurality of rotating bolts 43, and the rotating bolts 43 are used to fix the chip module 44 and the adapter module 45. The other side of the partition 41 is threadedly connected with a plurality of fixing bolts 42, and the plurality of fixing bolts 42 are used to fix the partition 41 inside the body 1.

[0039] Specifically, the partition 41 securely fixes the chip module 44 and the adapter module 45 through the rotating bolts 43 on one side, ensuring the stable operation of the internal components; while the fixing bolts 42 on the other side firmly install the partition 41 inside the body 1, enhancing the overall structural strength of the device.

[0040] like Figure 5 and Figure 6 As shown, in this embodiment, a connecting plate 47 is fixedly connected to the upper surface of the partition 41, and an antenna plate 46 is fixedly connected to the interior of the connecting plate 47. The connecting plate 47 can be snapped into the limiting plate 14, and the antenna plate 46 can be buckled between the connecting plate 47 and the limiting plate 14 to protect the antenna plate 46. An antenna module 49 is provided on the lower surface of the partition 41, and a top plate 410 is fixedly connected to one side of the antenna module 49, and the top plate 410 is used to protect the antenna module 49.

[0041] Specifically, the connecting plate 47 fixed to the upper surface of the partition 41 and the internal antenna plate 46 form a protective structure. By snapping with the limiting plate 14, the antenna plate 46 is effectively buckled in the middle, which plays a good protective role and avoids interference and damage to the antenna plate 46 by external factors. At the same time, the antenna module 49 on the lower surface of the partition 41 is covered by the top plate 410, further enhancing the protection of the equipment. This design not only ensures the stable transmission of the antenna signal, but also greatly improves the durability and safety of the equipment, and provides a strong guarantee for the stable operation of the equipment in various complex environments.

[0042] Working principle: first, start the printer through the switch 2, then, the rotating roller 18 in the driving component starts to rotate in the machine body 1, and the friction stripes on its surface effectively increase the friction between it and the label tape 15, ensuring that the label tape 15 can move stably and smoothly. At the same time, the print head accurately controls the heating and cooling of each tiny electronic component according to the preset pattern and text information, so that the ink on the carbon tape melts after being heated and is accurately transferred to the label paper 16. During the printing process, the limiting component 11 plays a key role. It not only limits the label tape 15 to prevent it from deflecting, but also effectively avoids the wrinkle problem of the label tape 15 by smoothing it, ensuring the stability of the printing quality. The thermal transfer printer achieves high-speed and accurate printing effects by virtue of its precise hot pressing device 3 and efficient driving component. At the same time, the upper cover 113 can be buckled and separated from the machine body 1 through simple operations, so that a new label tape 15 can be replaced conveniently and quickly. During the printing process, the built-in motor provides power, and the output end of the motor drives the fixed driving gear 17 to rotate, thereby driving the rotating roller 18 to rotate, and the label tape 15 on the circumferential surface of the rotating roller 18 moves accordingly to realize the printing process. This design simplifies the transmission structure, improves the transmission efficiency, ensures the smooth and continuous transportation of the label tape 15, is conducive to improving the printing quality and efficiency, and at the same time reduces energy consumption and noise, and enhances the stability and durability of the printer; In addition, the cooperation between the limiting column 19 fixed inside the machine body 1 and the long cleaning plate 114, as well as the auxiliary function of the positioning plate 31, is realized. Before printing, the long cleaning plate 114 uses the structural advantage of being fixed to the limiting column 19 to clean the surface of the passing label tape 15, effectively remove dust and oil, and ensure the printing quality. At the same time, the positioning plate 31 limits the label tape 15 when the label tape 15 is output, ensuring that the label tape 15 moves stably along the predetermined path to avoid dislocation or deviation. This design not only improves the printing clarity, but also enhances the stability and reliability of the equipment, providing a strong guarantee for high-quality printing. The limit assembly 11 further optimizes the transmission and printing effects of the label tape 15 by adding two spring pieces 110 fixed to the inner wall of the body 1. During the transmission of the label tape 15, the two spring pieces 110 exert moderate pressure on both sides of the label tape 15, which can not only effectively smooth out the deflection that may be caused by external force or uneven internal tension, but also ensure the stable transmission of the label tape 15 in the longitudinal direction and avoid the occurrence of offset. This design significantly improves the printing accuracy and the smoothness of the transmission of the label tape 15.
