Problems solved by technology

[0003] However, the printing quality of the existing thermal transfer ribbon cartridge is poor, and the printing effect is unstable: the handwriting is often unclear when printing, which makes the staff unclear, and then there may be work errors; under normal circumstances: the print head Heating to a certain temperature to print the toner on the ribbon to the label, while the existing ribbon cassette, the ribbon shaft in the ribbon cassette does not rotate smoothly during the working process, the reason is that the ribbon shaft and the ribbon cassette and The deviation of the coaxiality of the printer is relatively large, and it is not easy to align during installation, and the assembly is difficult
When the ribbon is wrinkled, it will reduce the heating energy of the print head, and eventually the printed writing (at the pen) will have poor weather resistance
At the same time, the structure of the existing thermal transfer carbon ribbon cassette is complicated, especially when assembling the positioning parts used to support the two ends of the carbon ribbon shaft, the positioning parts at the front end must first be put into the inner shell, and fixed on the inner shell by buckles, etc. , and then assemble the positioning parts at the rear end, the shell spring, etc. In this process, special tools are required, the assembly speed is slow, and the labor intensity is high, resulting in low production assembly efficiency and poor coaxiality

Embodiment 1

[0053] Such as Figure 1 to Figure 3 As shown, the present invention provides a thermal transfer ribbon cassette structure, including a ribbon cassette shell 1, two hollow support shafts 4 and two hollow ribbon shafts 3, the support shaft 4 passes through the center of the ribbon shaft 3 However, the outer wall of the support shaft 4 is provided with a plurality of convex strips 41 parallel to the axis of the support shaft 4. The convex strips 41 are distributed along the circumferential direction, and the height of the convex strips 41 gradually decreases from the middle to both ends in the length direction, forming a The arc shape is convenient for inserting the carbon ribbon shaft 3. The support shaft 4 has an interference fit with the inner wall of the carbon ribbon shaft 3 through the convex strip 41. The inner wall of the carbon ribbon shaft 3 can also be provided with a card slot to cooperate with the convex strip 41, so that the carbon ribbon The shaft 3 can rotate synch...

Embodiment 2

[0059] Such as Figure 4 As shown, in order to better fix the carbon ribbon shaft 3 and improve the coaxiality and stability during rotation, this example adds a carbon ribbon cassette inner shell 2 on the basis of embodiment 1, and the carbon ribbon cassette inner shell 2 includes a base 22 and two carbon ribbon bins 21 vertically arranged on the base 22 for accommodating the ribbon shaft 3, the ribbon bin 21 is integrally formed with the base 22, and the ribbon shaft 3 includes the ribbon supply end ribbon shaft 3 and the ribbon recovery The end carbon ribbon shaft 3, the base 22 is provided with a plurality of second snap joints 24 and a plurality of wedge-shaped bosses 23, the ribbon cassette shell 1 is provided with a third snap joint 12 corresponding to the second snap joint 24, and The limit groove 13 matched with the wedge-shaped boss 23; through the limit groove 13 for guidance and alignment, the second clamping joint 24 and the third clamping joint 12 are clamped tog...

Embodiment 3

[0062] Such as Figure 5 As shown, the difference between this example and Embodiment 2 is that the support assembly is an annular round platform 55 made of elastic material, the support assembly is in clearance fit with the positioning shaft 11, and the rear end of the support shaft 4 extends into the support assembly. or gap fit. The annular round platform 55 can be made of elastic materials such as sponge body and rubber. The pressure on the carbon ribbon shaft 3 through the support assembly is converted into the friction force when the ribbon shaft 3 rotates, so that it has a supporting effect and prevents wrinkles. The clearance fit can reduce the swing of the rear end, thereby improving the stability of the rotation. The possibility of unclear text caused by wrinkles during printing is reduced, and the rest of the structure is the same as that of Embodiment 2.

[0063] The support assembly of the present invention can also be a part extended from the ribbon cassette sh...

Abstract

The invention provides a heat transfer printing ribbon box structure. The heat transfer printing ribbon box structure comprises a ribbon box shell, two supporting shafts and two hollow ribbon shafts, wherein the ribbon shafts sleeve the corresponding supporting shafts fixedly and rotate with the corresponding supporting shafts synchronously. A fastening mechanism for matching with a driving device of a printer and a limiting part for limiting each ribbon shaft to move forwards are arranged at the front end of each supporting shaft, a positioning shaft coaxial with each supporting shaft is arranged on the ribbon box shell, a supporting component sleeves each positioning shaft and butts against the rear end face of each ribbon shaft, and the rear ends of the supporting shafts are movably connected with the corresponding positioning shafts or the corresponding supporting components in a sleeved manner. The heat transfer printing ribbon box structure has the advantages that the heat transfer printing ribbon box structure is simple and fewer than a traditional structure in component, so that assembly error is reduced; aligning and assembling are facilitated through various fastening modes, and accordingly, production efficiency is high; since the whole supporting shafts pass through the ribbon shafts and are supported by the supporting components, rotating coaxiality of the ribbon shafts is good, wrinkling conditions can be reduced, and printing quality is improved.

Description

technical field [0001] The invention relates to the technical field of printing consumables, in particular to a thermal transfer carbon ribbon box structure. Background technique [0002] The existing printing technology is divided into: pin type, heat sensitive, thermal transfer printing. Due to its slow speed, the needle type is currently used for bill printing; the thermal printing speed is fast, and it is now used in conventional printing fields (including label printing), but its weather resistance is poor. For light, sweat, water, etc., handwriting can only be preserved for a few months, and it is not suitable for environments that require long-term preservation of handwriting. Such as grid labeling system, network labeling system, pipeline labeling system and so on. They need labels with better weather resistance, longer shelf life, and more stability. Because thermal transfer printing can meet these needs, it is widely used. [0003] However, the printing quality ...
