Description

Technical Field

[0001] This utility model relates to the field of thermal transfer printing technology, and in particular to a multi-ribbon coaxial mounting printing device. Background Technology

[0002] With the development of information technology, especially the increasing demands for automation and product traceability in industries such as logistics, apparel, agriculture, healthcare, and chemicals, thermal transfer ribbon products have entered a period of rapid growth due to their ease of application, wide compatibility with printing materials, and simple equipment maintenance. In industrial printing scenarios, such as GHS chemical labels and garment care labels, the demand for multi-color printing is increasing. Traditional single-ribbon printing can no longer meet the needs of efficient and diversified printing. Therefore, multi-ribbon coaxial printing technology has become a key area that urgently needs to be developed.

[0003] In existing multicolor ribbon printing technologies, some international manufacturers, such as CAB of Germany, use a single ribbon and single printhead configuration. This involves connecting multiple independent ribbon printing mechanisms in series and using software control to drive these mechanisms with different printing information to achieve single-sheet layer printing. This results in complex product structures, high production costs, and significant ribbon waste. Other technologies attempt to mount multiple ribbons coaxially. However, in reality, variations in ribbon thickness, length, and allowance at the factory can lead to differences in ribbon diameter. When mounted coaxially, current product designs rely on a tight fit between the ribbon shaft and the ribbon core for precise ribbon transmission. Consequently, multiple ribbons on the same coaxial axis will exhibit different linear speeds due to diameter variations at the same transmission angular velocity. During batch printing, the cumulative difference in linear speed can cause ribbon slack, misalignment, or color overlay issues during printing. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-ribbon coaxial mounting printing device, which aims to improve the problem that when multiple ribbon rolls are mounted on a coaxial axis, the difference in ribbon roll diameter will cause inconsistent tape feed during coaxial rotation, making it impossible to achieve stable multi-ribbon printing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-ribbon coaxial mounting printing device, comprising a ribbon printer core, a ribbon supply damping frame interface and a ribbon take-up motor interface on the ribbon printer core, a ribbon mounting shaft installed at the ribbon supply damping frame interface, a ribbon take-up shaft installed at the ribbon take-up motor interface, a second ribbon core and a first ribbon core installed on the ribbon mounting shaft, ribbon core key sleeves installed on both sides of the second ribbon core, passing through the ribbon mounting shaft, ribbon core sliding sleeves installed on both sides of the first ribbon core, passing through the ribbon mounting shaft, and ribbon limiting rubber rings provided at both ends of the ribbon mounting shaft.

[0006] Furthermore, the carbon ribbon key ferrule is provided with a carbon ribbon key ferrule drive connection fitting.

[0007] Furthermore, a carbon belt drive mounting groove is provided on the carbon belt mounting shaft.

[0008] Furthermore, the carbon ribbon take-up shaft is provided with a carbon ribbon positioning groove for traction and positioning of the carbon ribbon. The carbon ribbon is placed in the groove and wound around the shaft by its own weight for recycling.

[0009] This utility model has the following beneficial effects:

[0010] 1. In this utility model, by using a multi-ribbon coaxial mounting structure and the cooperation of components such as the ribbon mounting shaft and the ribbon core key sleeve, a single printhead can drive multiple ribbons and multiple colors for one-time printing. This eliminates the need for multiple independent printheads and ribbon mechanisms in series for color separation, significantly reducing product design complexity and cost. At the same time, the label can be designed horizontally according to the ribbon arrangement, making full use of the printer's printing width, which improves printing efficiency and saves ribbon.

[0011] 2. In this utility model, the design of components such as the ribbon core key sleeve and the ribbon core sliding sleeve in the device makes it easy to replace the ribbon to adapt to different printing needs. The operation is simple and labor-saving, and no special consumables are required. It is applicable to existing ribbons and machines on the market, and there are no specific requirements for its application. It has wide applicability and practicality. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-5 This utility model provides an embodiment of a multi-ribbon coaxial mounting printing device, comprising a ribbon printer core 2, a ribbon supply damping frame interface 201 and a core ribbon take-up motor interface 202, a ribbon mounting shaft 1 installed at the ribbon supply damping frame interface 201, a ribbon take-up shaft 8 installed at the core ribbon take-up motor interface 202, a second ribbon core 3 and a first ribbon core 7 installed on the ribbon mounting shaft 1, and ribbon core key sleeves 4 installed on both sides of the second ribbon core 3. A carbon ribbon mounting shaft 1 is pierced through the carbon ribbon core 7. Carbon ribbon core sliding sleeves 6 are installed on both sides of the carbon ribbon mounting shaft 1. Carbon ribbon limiting rubber rings 5 ​​are also provided at both ends of the carbon ribbon mounting shaft 1. Carbon ribbon core key sleeve 4 is provided with carbon ribbon core key sleeve transmission connection insert 401. Carbon ribbon mounting shaft 1 is provided with carbon ribbon transmission insert groove 101. Carbon ribbon take-up shaft 8 is provided with carbon ribbon positioning winding shaft groove 801, which is used to traction and position the carbon ribbon. The carbon ribbon is placed in the groove and wrapped around the shaft by its own weight for recycling.

[0021] Specifically, when the printer is working, the paper feed motor of the printer core 2 drives the paper feed shaft to move the printing paper. At the same time, the ribbon take-up motor drives the ribbon take-up shaft 8 to rotate through the interface, pulling and winding the ribbon. Since the largest diameter ribbon core 3 is fixed to the ribbon mounting shaft 1 through the ribbon core key sleeve 4, the ribbon supply damping mechanism of the printer core 2 maintains the ribbon tension based on the amount of ribbon core 3 fed. The smaller diameter ribbon core 7 is slidably engaged with the ribbon mounting shaft 1 through the ribbon core sliding sleeve 6. Due to the characteristic that the smaller the diameter, the lower the linear velocity when rotating on the same axis, the sliding adjustment of the ribbon core sliding sleeve 6 compensates for the difference in ribbon feed with the ribbon core 3, achieving synchronous ribbon feed with the coaxial ribbon. At the same time, the ribbon limiting rubber rings 5 ​​on both sides of the ribbon group on the ribbon mounting shaft 1 limit the axial displacement caused by the traction force when the ribbon core is fed. The ribbon positioning groove 801 of the take-up shaft 8 achieves automatic ribbon tightening through gravity winding, reducing offset tension and ultimately ensuring consistent ribbon feed when printing multiple ribbons coaxially, significantly improving print quality and efficiency. The ribbon mounting shaft 1, which carries the ribbon, is installed on the ribbon supply damping frame interface 201 of the ribbon printer core 2. When the ribbons are coaxially installed, the ribbon core key sleeves 4 are installed on both sides of the largest diameter ribbon core 3, and are installed in the corresponding positions through the ribbon drive insert 101 designed on the ribbon mounting shaft 1. The ribbon core sliding sleeves 6 are installed on both sides of other smaller diameter ribbon cores 7, and are inserted into the ribbon mounting shaft 1 accordingly. After the ribbon mounting shaft 1 inserts the corresponding ribbon, ribbon limiting rubber rings 5 ​​are respectively fitted on both sides of the shaft body at the corresponding position of the installed ribbon group. The ribbon take-up shaft 8 is used to fix and position the ribbon traction end, and is installed on the ribbon take-up motor interface 202 of the ribbon printer core.

[0022] Working Principle: This multi-ribbon coaxial printing device uses a printer core 2 to control the paper feed motor and ribbon rewind motor for synchronous printing. The ribbon is primarily driven by the ribbon rewind motor, which pulls the ribbon on the ribbon mounting shaft 1 via the ribbon rewind shaft 8 at its mounting interface. Since the main factor affecting the ribbon feed rate in multi-ribbon coaxial transmission is the inconsistent linear velocity despite the same angular velocity due to different ribbon diameters, this invention uses a ribbon core 3 with the largest diameter to be fixedly connected to the ribbon mounting shaft 1 via a ribbon core key sleeve 4. This allows the printer's ribbon transmission mechanism to maintain tension via a damping mechanism on the ribbon mounting shaft 1, and controls the ribbon feed rate according to the printing speed. The remaining smaller diameter ribbon cores 7 are mounted on the ribbon mounting shaft 1 via ribbon core sliding sleeves 6 and are in a free sliding state. Because the coaxial transmission angular velocity is the same, they will passively follow the feeding rhythm of the large diameter ribbon. Through the sliding adjustment of the ribbon core sliding sleeves 6 and the ribbon mounting shaft 1, the feeding amount is made consistent with the large diameter ribbon. The ribbon limiting rubber ring 5 restricts the positional deviation of the sliding ribbon core 2 3 on the ribbon mounting shaft 1. The ribbon positioning winding groove 801 of the ribbon take-up shaft 8 achieves automatic ribbon tightening through gravity winding. It automatically tightens during feeding without adhesion, reduces offset tension, solves the problem of inconsistent feeding amount caused by different diameters of multiple coaxial ribbons, and ensures the printing quality of coaxial multicolor printing.
