Description

TECHNICAL FIELD

[0003] The working principle of the existing bar code printer is mainly based on two technologies of thermal printing and thermal transfer printing. When preparing to print a bar code, the bar code data is first transmitted to the bar code printer through a computer or other equipment. After the processor of the printer receives the data, it is converted into specific printing instructions. In thermal printing, the print head heats the specially designed thermal paper, so that the chemical coating changes color, thereby showing the bar code, text or pattern. In thermal transfer printing, the print head heats the carbon tape, so that the ink on the carbon tape melts and transfers to the label material, forming a permanent bar code. The sensor monitors the position and state of the printing paper in real time to ensure that the bar code can be printed completely.

[0004] Although the existing bar code printer with RFID function is powerful, the high cost makes it difficult for small and medium-sized enterprises to bear, which limits its market penetration.

[0033] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application will be further described below in combination with the specific embodiments.

[0034] Embodiment one: as​Figures 1 to 6 As shown, the RFID barcode printer capable of resisting metal interference provided by the embodiment of the application comprises a body 1, a switch 2 arranged on one side of the body 1, a hot pressing device 3 rotatably arranged on the upper surface of the body 1, the hot pressing device 3 being a printing head of a hot transfer printer in the prior art, a paper outlet 13 formed on one side of the body 1, a label tape 15 placed in the paper outlet 13, the label tape 15 having printed label paper 16, an upper cover 113 rotatably arranged above the body 1, two positioning blocks 112 elastically arranged on one side of the upper cover 113, a hook block 111 fixedly connected to the lower surface of each positioning block 112, the two hook blocks 111 being capable of being clamped with the body 1 to complete the clamping of the upper cover 113 with the body 1, so as to facilitate replacement of the label tape 15, a driving assembly rotatably arranged in the body 1, the driving assembly being used to drive movement of the label tape 15, the driving assembly comprising a rotating roller 18 rotatably arranged in the body 1, a friction stripe being formed on the circumferential surface of the rotating roller 18, the friction stripe being used to increase the friction force with the label tape 15, and a limiting assembly 11 arranged in the body 1, the limiting assembly 11 being used to limit and smooth the label tape 15, so as to prevent wrinkles of the label tape 15;

[0035] In the hot transfer printer, the printing head is the most core component, which is composed of many small electronic elements, can rapidly and accurately control heating and cooling of each element, realizes high-speed ink transfer, and enables fine and high-definition patterns and characters to be presented, and the carbon tape is usually composed of a substrate, an ink layer and a protective layer, the ink layer contains special ink, and when subjected to the heating action of the printing head, the ink is melted and transferred to the printing medium.

[0036] Specifically, although the existing barcode printer is powerful, the high cost makes it difficult for small and medium-sized enterprises to bear, which limits its market penetration. Secondly, the RFID technology is relatively complex, which puts high requirements on the research and manufacture of equipment, increases the difficulty of technology implementation, and in addition, such printers are picky about the use environment, not only requiring stable power supply, but also requiring to be used with specific read-write equipment, which undoubtedly narrows its potential application range. In summary, cost, technical difficulty and environmental adaptability are the main obstacles to the popularization of the RFID barcode printer at present.

[0037] Therefore, the application solves the problem by setting a certain structure. First, the printer is started by the switch 2. Then, the rotating roller 18 in the driving assembly starts to rotate in the body 1, and the friction stripes on the surface effectively increase the friction with 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 element 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. In the printing process, the limiting assembly 11 plays a key role. It not only limits the label tape 15 to prevent it from deviating, but also effectively avoids the problem of wrinkles of the label tape 15 through the straightening effect, ensuring the stability of the printing quality. The thermal transfer printer realizes high-speed and accurate printing effect by virtue of its precise hot pressing device 3 and efficient driving assembly. At the same time, the on-machine cover 113 can be buckled and separated from the body 1 through simple operation, so that the new label tape 15 can be replaced conveniently and quickly.

[0038] Through the advanced thermal transfer technology, the high adhesion and durability of the label on various materials are ensured. This unique printing technology not only improves the production efficiency, but also enhances the stability of the label in different environments.

[0039] The problems of high cost, technical barriers and poor adaptability of the bar code printing in the prior art are solved.

[0040] As shown in Figure 1 The driving assembly of the embodiment includes a built-in motor arranged inside the body 1. The output end of the built-in motor is fixedly connected with a driving gear 17. One side of the driving gear 17 is fixedly connected with a rotating roller 18. The circumferential surface of the rotating roller 18 is provided with a label tape 15.

[0041] Specifically, the built-in motor provides power. The output end of the motor drives the fixed driving gear 17 to rotate, thereby driving the rotating roller 18 to rotate. The label tape 15 on the circumferential surface of the rotating roller 18 moves accordingly, realizing the printing process. This design simplifies the transmission structure, improves the transmission efficiency, ensures the stable and continuous conveying of the label tape 15, is conducive to improving the printing quality and efficiency, reduces the energy consumption and noise, and enhances the stability and durability of the printer.

[0042] As shown in Figure 1 During the rotation of the thermal transfer printer, the driving assembly drives the rotating roller 18 to rotate.

[0043] Specifically, by driving the rotating roller 18 to rotate, the rotating roller 18 not only assists the hot pressing device 3 to apply uniform heat and pressure to the printing material to ensure clear printing of the image, but also undertakes the important task of driving the label tape 15 to move stably and continuously to the paper outlet 13.

[0047] Specifically, the limiting assembly 11 further optimizes the transmission and printing effect of the label tape 15 by adding two elastic sheets 110 fixed to the inner wall of the body 1. The two elastic sheets 110 moderately press the two sides of the label tape 15 during the transmission process of the label tape 15, which not only effectively straightens the label tape 15 that may be folded due to external force or uneven internal tension, but also ensures the stable transmission of the label tape 15 in the longitudinal direction, avoiding the occurrence of deviation. This design significantly improves the printing accuracy and the stability of the label tape 15 transmission, lays a solid foundation for high-quality and efficient printing, and also prolongs the service life of the printing equipment and the label tape 15.

[0049] Specifically, the auxiliary plate 12 and the limiting plate 14 fixedly connected on one side of the body 1 are ingeniously combined to jointly constitute the paper outlet 13, which 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 label paper 16 after printing, effectively preventing the curling phenomenon of the label paper 16 due to thermal expansion and contraction after heating printing. Not only does it improve the flatness and aesthetics of the printed product, but also ensures the smoothness and stability of the label paper 16 during the paper outlet process.

[0050] As Figure 4 and Figure 5 shown, the body 1 of the embodiment is fixedly connected with a partition plate 41 inside, one side of the partition plate 41 is fixedly connected with a conversion module 45, and the conversion module 45 is used for signal and data conversion.

[0051] Specifically, the partition plate 41 fixedly connected inside the body 1 carries the conversion module 45, which is responsible for signal and data conversion. This design ensures efficient and stable data transmission and improves the operating efficiency of the equipment.

In addition, a plurality of fixing columns 48 are used to fixedly connect the conversion module 45.

[0053] Specifically, the protective cover 4 fixedly connected on the surface of the conversion module 45 effectively resists potential damage to the conversion module 45 from the external environment, improving the durability and safety of the equipment. At the same time, the fixing columns 48 on the partition plate 41 not only stably support the chip modules 44, but also undertake the fixing task of the conversion module 45, ensuring the stability and efficiency of data transmission. This design optimizes the internal layout and enhances the overall performance and reliability of the equipment.

[0055] Specifically, the partition plate 41 realizes firm fixation of the chip module 44 and the adapter module 45 through the rotating bolt 43 on one side, ensuring stable operation of the internal components; and the fixing bolt 42 on the other side stably installs the partition plate 41 inside the machine body 1, enhancing the overall structural strength of the equipment.

[0056] As shown in Figure 5 and Figure 6 , the upper surface of the partition plate 41 of the embodiment is fixedly connected with the connecting plate 47, the inside of the connecting plate 47 is fixedly connected with the antenna plate 46, the connecting plate 47 can be clamped with 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. The lower surface of the partition plate 41 is provided with an antenna module 49, one side of the antenna module 49 is fixedly connected with a top plate 410, and the top plate 410 is used for protection of the antenna module 49.

This design not only ensures stable transmission of the antenna signal, but also greatly improves the durability and safety of the equipment, providing a strong guarantee for stable operation of the equipment in various complex environments.

[0058] The working principle is that first, the printer is started through the switch 2, then the rotating roller 18 in the driving assembly starts to rotate in the machine body 1, the friction stripes on the surface effectively increase the friction between the label tape 15, ensuring that the label tape 15 can move stably and smoothly, and at the same time, the print head accurately controls the heating and cooling of each tiny electronic element 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.
