Description

Technical Field

[0001] This invention relates to the field of printer technology, and in particular to a multifunctional thermal transfer printer with a modular overall layout and integrated mechanism. Background Technology

[0002] Thermal transfer printers, widely used in industrial signage, logistics labels, retail receipts, and other fields, work by heating a ribbon with a printhead, which transfers the ink from the ribbon to the surface of paper or a label, thus achieving high-definition printing of images and text.

[0003] Currently, most thermal transfer printers adopt a decentralized integrated structure, where the printhead main mechanism, rollers, ribbon supply and recycling components, and electronic control board are directly fixed to an integrated bracket inside the machine casing. This lack of unified layout planning often leads to spatial interference between the printhead main mechanism, roller assembly, gear sets, and synchronous belt drive components and the electronic control and sensor components. Excessive internal space results in a large overall size, making it difficult to adapt to the installation requirements of confined industrial environments. Furthermore, some existing models, in order to reduce space, tightly integrate various functional components, with the printhead assembly, drive assembly, and electronic control assembly closely packed together without adequate heat dissipation channels. When maintaining individual parts, multiple parts must be disassembled and reassembled simultaneously, leading to low maintenance efficiency, heat buildup, and impacting long-term operational stability. This also easily causes paper jams, ribbon loosening and breakage, and label misalignment, directly affecting printing efficiency and product quality. Summary of the Invention

[0015] The technical effects and advantages of this invention are as follows: 1. This invention features a compact and independent layout of the main body, outer shell, label mechanism, ribbon mechanism, paper guide mechanism, printing component, and display component, facilitating disassembly, maintenance, and functional upgrades. The support component supports the printing component and feeds paper, while the paper guide mechanism and printing component are functionally independent yet tightly connected, improving functional integrity and ease of disassembly. The label mechanism, through a label recycling port and a motor-driven recycling group, can automatically reel in labels and waste paper that have not detached from the paper guide, avoiding paper jams and ribbon loosening or breakage, thus improving printing stability and efficiency and solving the pain point of messy paths in existing systems. The various components work together to enable the ribbon, label, and paper guide to operate along different paths. 2. This invention utilizes the appropriate gap between the paper guiding mechanism and the ribbon mechanism. In the ribbon mechanism, the filter shaft removes impurities and tensions the ribbon, the sensor detects the ribbon balance and feeds it back to the control board, and the guide shaft ensures the ribbon adheres to the print head, guaranteeing stable ribbon feeding from supply to return and reducing printing defects caused by impurities or looseness. In the paper guiding mechanism, the limiting component prevents label offset, the rubber roller is driven by the transmission assembly as the paper feeding power wheel, and the thermal sheet support component fixes the print head and protects the rubber roller. Combined with the torsion spring adjustment of the pressure rotating shaft, the contact pressure between the print head and the rubber roller can be precisely controlled to adapt to labels of different thicknesses and ensure clear and uniform printing. In the display assembly, the control board receives signals from the ribbon sensor, gap sensor, and print head heating signal, driving the transmission assembly and display panel, thus realizing systematic intelligent control of the entire printing process. 3. This invention utilizes a combination of transmission components and heat dissipation components. The transmission components centrally drive multiple rotating shafts, providing stable power for label recycling, ribbon loading and unloading, and paper guiding. This reduces transmission losses and improves operational reliability. The added detachable heat dissipation components are tightly fitted to the ventilation holes of the main body side plate and outer shell through square corrugated telescopic tubes. The negative pressure suction of the cooling fan allows hot air to enter the rectangular frame through the ventilation mesh and be discharged from both ends. Its elastic rubber material facilitates quick assembly and disassembly, effectively promoting the circulation and dissipation of heat inside the machine cavity and ensuring stability during long-term operation.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] The main component 100 includes a main side plate 101, a main bottom plate 102, a rear baffle 103, a drive body 104, and a front baffle 105. The top of the main side plate 101 is connected to the outer shell 200 via a hinge. A transmission component 700 is installed in the inner cavity of the main side plate 101.

The rear baffle 103 is fixed to one end of the main side plate 101 with screws. The drive body 104 is inserted and installed on the top of the main side plate 101. The connection between the drive body 104 and the transmission component 700 is used for the rotation of the label mechanism 300, the ribbon mechanism 400, and the paper guide mechanism 500. The front baffle 105 is snapped into the other end of the main side plate 101 and is used for label paper output. It should be noted that the transmission assembly 700 is composed of a motor, transmission gears and a conveyor belt assembly. The transmission assembly 700 is an existing drive assembly. The transmission end of the transmission assembly 700 can be connected to the rotating shaft on the drive body 104. Multiple rotating shafts on the drive body 104 are connected to the ribbon mechanism 400 and the paper guide mechanism 500, which facilitates the stable operation of the printer.

[0022] In the modular design of this multifunctional thermal transfer printer, the main body component 100 serves as the overall structural frame. Through the combination of the main body side plate 101, the main body base plate 102, the rear baffle 103, the drive body 104, and the front baffle 105, the outer shell 200 is hinged and snapped together, ensuring that the outer shell can be opened and closed flexibly for easy maintenance. At the same time, the transmission component 700 in the inner cavity of the main body side plate 101 drives multiple rotating shafts on the main body 104 through a motor, gears, and belts, providing stable power to the label mechanism 300, the ribbon mechanism 400, and the paper guide mechanism 500. This layout enables centralized control of the transmission system, reduces transmission losses, and improves operational reliability.

[0023] Additionally, the label mechanism 300 includes a label recycling port 301 and a label recycling assembly 302. The label recycling port 301 is snapped into the inner cavity of the front baffle 105 and is used for recycling labels that have not detached from the guide paper. The label recycling assembly 302 is mounted on one end of the main body side plate 101 via a motor drive and is used for label paper recycling, allowing waste paper and waste labels to be wound up and recycled by the winding end on the label recycling assembly 302. In the label mechanism 300, the label recycling port 301 is snapped into the inner cavity of the front baffle 105 and is equipped with... The bracket assembly 503, combined with the motor-driven label recycling assembly 302, automatically rewinds and recycles labels and waste paper that have not detached from the paper guide, preventing label scattering or paper jams and improving the continuity and cleanliness of the printing process. The transmission assembly 700 within the main body side plate 101 drives multiple rotating shafts on the main body 104 via a motor, gears, and belts, providing stable power to the label mechanism 300, ribbon mechanism 400, and paper guide mechanism 500. This layout allows for centralized control of the transmission system, reducing transmission losses and improving operational reliability. In the label mechanism 300, the label recycling port 301 engages with the front baffle 105 cavity and, in conjunction with the bracket assembly 503 and the motor-driven label recycling assembly 302, automatically rewinds and recycles labels and waste paper that have not detached from the paper guide, preventing label scattering or paper jams and improving the continuity and cleanliness of the printing process.

[0024] Furthermore, the ribbon mechanism 400 includes a ribbon filter shaft 401, a ribbon sensor 402, a ribbon recycling assembly 403, a ribbon guide shaft 404, and a ribbon supply component 405. The ribbon filter shaft 401 passes through the side of the main body side plate 101 and is installed between the ribbon supply component 405 and the printing assembly 600, located in the middle section of the ribbon path. The ribbon filters impurities on the ribbon by sliding on the outer wall of the ribbon filter shaft 401, and facilitates ribbon tensioning. The ribbon sensor 402 is fixed at an angle to the side of the main body side plate 101 and is used to detect whether there is any excess ribbon. The ribbon recycling assembly 403 is rotatably inserted through the top of the main body side plate 101 via a bearing. The ribbon recycling assembly 403 is used to recycle waste ribbon after printing, and the end of the ribbon recycling assembly 403 is connected to the transmission... The component 700 is connected to facilitate the rotation and recycling of the ribbon recycling group 403. The ribbon guide shaft 404 is rotatably inserted through the side of the main body side plate 101 via a bearing. The ribbon guide shaft 404 is used to guide the ribbon and is installed on the ribbon feeding path to facilitate the ribbon to fit the print head. The ribbon supply component 405 is rotatably inserted through the top of the main body side plate 101 via a bearing. The ribbon supply component 405 is arranged adjacent to the ribbon recycling group 403, and one end of the ribbon recycling group 403 and the ribbon supply component 405 is connected to the transmission component 700. The ribbon supply component 405 is equipped with a ribbon roll to provide ribbon supply for printing. The ribbon passes through the ribbon supply component 405, the ribbon guide shaft 404, the ribbon filter shaft 401, the ribbon sensor 402, and the ribbon recycling group 403 in sequence to ensure a stable ribbon supply.

[0025] It should be noted that the ribbon mechanism 400 filters impurities and tensions the ribbon between the ribbon supply component 405 and the printing component 600 via the ribbon filter shaft 401. The ribbon sensor 402 detects the remaining ribbon in a slanted fixed manner and transmits a signal to the control board 803. The ribbon recycling group 403 is driven by the transmission component 700 to recycle waste ribbon. The ribbon guide shaft 404 keeps the ribbon in contact with the main print head 603, thereby ensuring stable ribbon feeding from supply to recycling and effectively reducing printing defects caused by impurities or looseness.

[0026] The paper guiding mechanism 500 includes a paper guiding limiter 501, a paper supply shaft 502, and a support assembly 503. The paper guiding limiter 501 is installed at the bottom of the main body side plate 101 and is used to limit the left and right displacement of the label paper. The paper supply shaft 502 is fixed to one end of the main body side plate 101 by screws. The paper supply shaft 502 is used to hold the label paper roll and provide a supply source for the paper. The support assembly 503 is installed at the top of the front baffle 105. The label recycling port 301 is snapped into the bottom of the inner cavity of the support assembly 503. The support assembly 503 is used in conjunction with the printing assembly 600.

[0027] The support assembly 503 includes a lower body 531 of the paper guide, a rubber roller 532, and a thermal sheet support 533. The lower body 531 of the paper guide is installed on the upper surface of the main body base plate 102 by screws. The label collection port 301 is installed in the inner cavity of the lower body 531 of the paper guide. The rubber roller 532 is rotatably engaged with the top of the lower body 531 of the paper guide. One end of the rubber roller 532 is connected to the transmission assembly 700. The thermal sheet support 533 is engaged with the top of the lower body 531 of the paper guide. The printing assembly 600 is located on one side of the top of the thermal sheet support 533. The rubber roller 532 is located at the front end of the main body assembly 100 and directly below the printing assembly 600. The rubber roller 532 acts as a paper feeding power wheel to move the label paper. The thermal sheet support 533 is connected to the top of the lower body 531 of the paper guide to protect the rubber roller 532 and to cooperate with the fixation of the main print head 603.

[0028] Furthermore, the printing assembly 600 includes a gap sensor 601, a pressure rotation shaft 602, and a main print head 603. The gap sensor 601 is installed at one end of the lower body 531 of the paper guide and is mounted on the paper feed path of the printing assembly. The gap sensor 601 is used to detect the label paper gap and label position. The pressure rotation shaft 602 is mounted on the top of the thermal sheet support 533. The main print head 603 is snapped onto one end of the thermal sheet support 533. The pressure rotation shaft 602 is installed on the side of the main body side plate 101. The torsion of the pressure rotation shaft 602 is used for the installation and removal of the main print head 603 on the thermal sheet support 533. The end of 2 is equipped with a torsion spring so that its pressure rotation shaft 602 can be rotated and adjusted on the main print head 603, which can control the contact pressure between the main print head 603 and the rubber roller 532. The printing end of the main print head 603 and the rubber roller 532 form a tangential contact printing area. Through the contact between the rubber roller 532 and the head of the main print head 603, and the connection between the side of the rubber roller 532 and the transmission component 700 through the drive body 104, the label paper is driven to rotate and be transported by the motor. The main print head 603 is the core of the printing component. The main print head 603 is fixed by the thermal sheet bracket 533, so that the main print head 603 is stable directly above the rubber roller 532.

[0029] The ribbon mechanism 400 filters impurities and tensions the ribbon between the ribbon supply unit 405 and the printing unit 600 via the ribbon filter shaft 401. The ribbon sensor 402 detects the remaining ribbon amount in a slanted fixed manner and transmits a signal to the control board 803. The ribbon recycling group 403 is driven by the transmission component 700 to recycle waste ribbon. The ribbon guide shaft 404 keeps the ribbon in contact with the main print head 603, thereby ensuring stable ribbon feeding from supply to recycling and effectively reducing printing defects caused by impurities or looseness.

In the display assembly 800, the display panel 801, the power main board 802, and the control board 803 are respectively fixed to the front and inner cavity of the main body side plate 101.

The cooling fan 904 is used to draw air into the cavity formed by the main body side plate 101 and the outer casing 200. The cooling fan 904 is driven by a motor, so that the fan blades on the cooling fan 904 can draw air under negative pressure, so that hot air can enter the inner cavity of the rectangular frame 901 through the ventilation mesh 903 and can be discharged through the square corrugated telescopic tubes 902 at both ends. The elastic rubber of the square corrugated telescopic tubes 902 makes it easy to quickly install and remove the heat sink 900 on 102 and facilitates the rapid dissipation of heat.
