Description
Technical Field
[0001] This utility model relates to the field of printing equipment manufacturing, and in particular to a multifunctional thermal transfer printer. Background Technology
[0002] Thermal transfer printers are widely used in the field of ID card production, enabling the printing of clear text, patterns, and photos on the surface of ID cards. As the application scenarios for ID cards continue to expand, the functional requirements for ID card production equipment are also increasing. In addition to basic printing functions, they need to possess multiple capabilities such as data writing and multi-format adaptation. Currently, most ID card printers on the market can only process ID cards of a single format, and they lack effective identification and management mechanisms for the use of printing tapes, easily leading to the problem of incorrect tape selection and affecting print quality.
[0003] Existing card printers typically have their printing and data writing modules distributed across different devices, requiring multiple transfers of cards between different machines to complete the entire production process. This not only reduces work efficiency but also easily leads to card damage or information errors. Furthermore, because the height of the conveyor channel is often fixed and cannot be adjusted to accommodate cards of varying thicknesses, the printer is limited in processing different card sizes and cannot meet diverse card production needs.

[0035] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0036] Reference Figure 1-7A multi-functional thermal transfer printer for printing ID cards includes a printing component 300, a feeding component 400, a writing component 500, and a conveying component 600. The printing component 300 performs thermal transfer printing on the ID cards. The feeding component 400 includes a feeding roller and a mounting base. The feeding roller is equipped with a first identification module 410, and the mounting base is equipped with a corresponding second identification module 420. When the two identification modules match, they provide printing tape to the printing component 300. The writing component 500 writes data to the ID cards. The conveying component 600 is located between the writing component 500 and the printing component 300, and has an adjustable-height conveying channel for conveying ID cards of different thicknesses. The writing component 500, the conveying component 600, and the printing component 300 are arranged sequentially along the ID card conveying direction.
[0037] Understandably, when this multi-functional thermal transfer printer produces ID cards, the writing component 500 first writes data onto the blank ID card, such as employee numbers and access permissions, into the card's chip. Then, the card moves towards the printing component 300 via the conveying component 600. The conveying channel of the conveying component 600 can be height-adjusted according to the card's thickness, allowing it to smoothly convey ID cards of different sizes, such as student IDs and work IDs, with thicknesses ranging from 0.3mm to 1.0mm. The printing component 300 uses thermal transfer technology to print on the card's surface, capable of printing photos, text, and patterns, thus completing the entire ID card production process. Throughout the process, the various components are arranged in an orderly manner along the card's conveying direction, ensuring the continuity and efficiency of ID card production. It should be noted that before printing, the first identification module 410 on the feed roller in the feed assembly 400 will match and identify with the second identification module 420 on the mounting base. Only when the two identification modules match successfully will the feed assembly 400 provide the correct printing tape to the printing assembly 300. This can avoid printing quality problems caused by using the wrong tape.
[0038] In some embodiments, the first identification module 410 is a first radio frequency identification (RFID) chip, fixed to the axial end of the feed roller; the second identification module 420 is an induction coil, fixed on the mounting base at a position opposite to the first RFID chip; the first RFID chip and the induction coil form an interactive verification path through electromagnetic induction coupling. Specifically, by fixing the first RFID chip as the first identification module 410 to the axial end of the feed roller, and simultaneously fixing the induction coil as the second identification module 420 on the mounting base, when the feed roller is installed in place, the first RFID chip and the induction coil will be in a relative position, and the two will generate a coupling effect through electromagnetic induction to form an interactive verification path. When the operator loads the feed roller containing the correct ribbon into the mounting base, the first RFID chip at the end of the feed roller will enter the sensing range of the induction coil. The electromagnetic field generated by the induction coil will activate the first RFID chip and transmit identification information. The printer will confirm the correct ribbon model through this interactive verification path before allowing printing to begin. This effectively prevents printing quality problems caused by using the wrong ribbon and ensures that the printing effect of each card meets the expected standard.
[0039] In some embodiments, refer to Figure 2 , 6 The writing component 500 includes a second radio frequency identification (RFID) chip 530, which is movably disposed at the entrance of the card delivery channel. The second RFID chip 530 can dynamically adjust its relative spatial position according to the physical position of the chip in the card to establish directional communication coupling with the chip.
[0040] Understandably, data is written using a movable second RFID chip 530, which is positioned at the entrance of the card delivery channel. This second RFID chip 530 can adjust its position according to the specific location of the chip in different cards, thereby achieving precise data writing. Since different batches or types of access cards may have differences in chip position, the second RFID chip 530 automatically adjusts its spatial position based on the physical location of the chip in the card to be written, ensuring optimal communication coupling with the chip within the card. This improves the success rate and stability of data writing. Specifically, when a card enters the card delivery channel, the second RFID chip 530 first detects the specific location of the chip within the card, then moves to the most suitable position, establishes stable directional communication coupling, and then accurately writes the data into the card chip, thus ensuring that each card is correctly written with the required data information.
[0041] Furthermore, refer to Figure 6The writing component 500 further includes a partition 510 and a cover plate 520. The second RFID chip 530 is detachably mounted on the mounting surface of the partition 510. The partition 510 has a signal port, and the projection area of the signal port covers the antenna radiation area of the second RFID chip 530. The cover plate 520 is detachably connected to the partition 510 to form a closed accommodating space. It is understood that the writing component 500 includes a partition 510 and a cover plate 520, wherein the second RFID chip 530 is detachably mounted on the mounting surface of the partition 510, and the projection area of the signal port designed on the partition 510 completely covers the antenna radiation area of the second RFID chip 530, ensuring effective transmission of radio frequency signals. The enclosed space formed by the detachable connection between the cover plate 520 and the partition plate 510 not only protects the second RFID chip 530 from external environmental influences, but also effectively shields against external electromagnetic interference. For example, when the printer is used in a complex office environment, this enclosed design can ensure that the data writing process is not interfered with by surrounding electronic devices, thus guaranteeing the data writing quality and accuracy of each card.
[0042] In some embodiments, refer to Figure 2 , 3 The conveying assembly 600 includes a fixed first conveying roller 610 and a movable second conveying roller 620. The first conveying roller 610 is located below as the driving roller, and the second conveying roller 620 is located above as the driven roller. The second conveying roller 620 is connected via an elastic component 630 and can move up and down relative to the first conveying roller 610 to form the height-adjustable conveying channel. It is understood that the second conveying roller 620 can move up and down relative to the first conveying roller 610 to form a height-adjustable conveying channel. When printing different types of cards, such as switching from thinner cards to thicker cards made of special materials, the second conveying roller 620 will automatically adjust its distance from the first conveying roller 610 under the action of the elastic component 630, achieving adaptive clamping of cards of different thicknesses. Adaptive adjustment ensures that cards of different specifications receive appropriate clamping force, thereby guaranteeing the stability and reliability of card conveying.
[0043] Furthermore, refer to Figure 2-5The printer also includes two opposing upright plates 200, with the first conveyor roller 610 and the printing assembly 300 positioned between the two upright plates 200. Both ends of the first conveyor roller 610 are fixedly connected to the upright plates 200. Each upright plate 200 has a guide groove 210, and both ends of the second conveyor roller 620 have bushings 621 slidably disposed within the guide groove 210. The guide groove 210 has parallel sidewalls arranged opposite to each other, and the outer wall of each bushing 621 is symmetrically provided with parallel guide planes that slide in contact with the sidewalls. It can be understood that the multi-functional thermal transfer printer has two opposing upright plates 200, which support and fix the conveyor assembly 600 and the printing assembly 300. The two ends of the first conveyor roller 610 are fixedly connected to the upright plates 200 to ensure its stability, while the guide grooves 210 designed on the upright plates 200 provide guiding support for the movement of the second conveyor roller 620. The bushings 621 at both ends of the second conveyor roller 620 can slide freely within the guide groove 210. The two parallel sidewalls of the guide groove 210 cooperate with the parallel guide planes symmetrically arranged on the outer wall of the bushing 621 to form a sliding guide mechanism. In use, the second conveyor roller 620 slides up and down within the guide groove 210 through the bushings 621 at both ends. Since the guide planes of the bushings 621 and the sidewalls of the guide groove 210 always maintain sliding contact, it can be ensured that the second conveyor roller 620 always remains horizontal when adjusting its height, avoiding tilting or deviation, thereby ensuring the stability and reliability of the card conveying process.
[0044] Furthermore, refer to Figure 2The bushing 621, protruding from the end of the upright plate 200, has an annular groove 6211. The elastic component 630 is a helical torsion spring, with an axially extending fixed arm and an abutting arm at its two ends. The fixed arm is fixedly connected to the upright plate 200, and the abutting arm is embedded in the annular groove 6211 and abuts against the bushing 621. The helical torsion spring has an annular elastic energy storage portion, which provides clamping force through radial compression deformation. Specifically, by providing an annular groove 6211 at the end of the bushing 621 protruding from the upright plate 200 and using a helical torsion spring as the elastic component 630, the two ends of the helical torsion spring are designed as an axially extending fixed arm and an abutting arm. The fixed arm is fixedly connected to the upright plate 200 to provide stable support, while the abutting arm is embedded in the annular groove 6211 of the bushing 621 and maintains abutment against the bushing 621. The annular elastic energy storage portion of the helical torsion spring provides appropriate clamping force through radial compression deformation. The second conveyor roller 620 will automatically adjust its position under the action of the helical torsion spring. At this time, the annular elastic energy storage part of the helical torsion spring will generate corresponding radial compression deformation, and transmit the pressure to the bushing 621 through the abutment arm, thereby enabling the second conveyor roller 620 to apply a suitable clamping force to the card. The design of the annular card groove 6211 ensures that the abutment arm can always act stably on the bushing 621, avoiding the deviation of the direction of the spring force, thus ensuring that cards of different thicknesses can obtain a stable and uniform clamping force during the conveying process.
[0045] In some embodiments, refer to Figure 3 The print head 310 of the printing assembly 300 is connected to the upright plate 200 via a rotatable bracket. The rotatable bracket includes a laterally extending adjusting bar 320, on which the print head 310 is fixed. The vertical distance between the print head 310 and the card is adjusted by rotating the adjusting bar 320. Understandably, during use, the operator can adjust the height of the print head 310 by rotating the adjusting bar 320 to maintain the optimal printing distance between the print head 310 and the card surface. Specifically, when processing thicker cards, the print head 310 can be moved upwards by rotating the adjusting bar 320 clockwise, increasing the vertical distance between the print head 310 and the card; when processing thinner cards, the print head 310 can be moved downwards by rotating the adjusting bar 320 counterclockwise, decreasing the vertical distance. This adjustable design ensures optimal printing results for cards of different thicknesses, avoiding printing quality problems caused by improper printing distance.
[0046] In some embodiments, refer to Figure 1-3It also includes a platform 700 set at the card entry point. The platform 700 is provided with a horizontally extending through groove 710 and two horizontally movable limiting parts 720. The two limiting parts 720 are arranged opposite each other to form a card positioning channel. A limiting post 730 with a screw structure is fixed at the bottom of the limiting part 720. The limiting post 730 passes through the through groove 710 and is slidably connected to the platform 700. The lower end of the limiting post 730 is provided with an abutment part with a diameter greater than the width of the through groove 710. The abutment part is locked to the bottom surface of the platform 700 by screwing. Understandably, each limiting part 720 has a fixed limiting post 730 with a screw structure at its bottom. These limiting posts 730 pass through the through slot 710 on the platform 700 and maintain a sliding connection with the platform 700. The lower end of the limiting post 730 is designed with an abutment part with a diameter larger than the width of the through slot 710. By rotating the screw, the abutment part can be locked to the bottom surface of the platform 700. In use, the operator can first loosen the locking state of the limiting post 730, then move the two limiting parts 720 laterally to adjust the width of the card positioning channel to match the width of the card to be processed. After adjustment, the limiting post 730 is rotated to lock the abutment part to the bottom surface of the platform 700, thereby fixing the position of the limiting part 720. This adjustable positioning structure ensures that cards of different sizes can obtain accurate entry positions and avoids card deviation when entering the conveying channel.
[0047] In some embodiments, refer to Figure 1-3 The system also includes a housing 100 and a display screen 800 mounted on the housing 100. The display screen 800 is electrically connected to the printing assembly 300, the feeding assembly 400, the writing assembly 500, and the conveying assembly 600. The display screen 800 is configured to display printing parameters and receive user input to adjust at least one parameter, such as printhead 310 pressure, conveyor channel height, and conveyor speed. Understandably, during use, operators can view the current printing parameter status through the display screen 800 interface and adjust parameters such as printhead 310 pressure, conveyor channel height, or conveyor speed as needed. Specifically, when processing thicker access cards, the printhead 310 pressure can be increased through the display screen 800 to ensure print clarity, while simultaneously increasing the conveyor channel height to accommodate the card thickness, and possibly reducing the conveyor speed to ensure print quality. Conversely, when processing thinner employee ID cards, the printhead 310 pressure and conveyor channel height can be reduced accordingly, and the conveyor speed can be appropriately increased to improve printing efficiency. This intelligent parameter adjustment interface allows the printer to more flexibly adapt to the printing needs of different types of cards, ensuring print quality while improving operational convenience.
