Description

Technical Field

[0001] The utility model relates to the technical field of thermal transfer printers, in particular to an integrated carbon ribbon box. Background Art

[0002] A ribbon cassette is a device used to store and supply ribbons, mainly used in barcode printers, label printers and other printing devices. A ribbon is a plastic or paper ribbon coated with special ink, used to print barcodes, labels and other information. A thermal transfer printer is a printing device that uses thermal transfer technology, which transfers the ink on the ribbon to various media such as paper, plastic, metal or fabric by heating.

[0003] If the pressure and damping of the ribbon cassette are not designed properly, the tension will be too small and the printing will be prone to wrinkles. At the same time, due to the high friction coefficient of the plastic parts, the damping during the rotation process is unstable, and the ribbon will get stuck. The supply end rotates on an axis. Due to the loose fit, the parallelism of the supply end is relatively low, resulting in inconsistent tension. The ribbon is prone to wrinkles during printing, affecting the printing effect.

[0004] Moreover, the tension requirements at the supply end and the recovery end are inconsistent. If the tension is adjusted using a spring, it will cause difficulty in adjusting the tension, which is not convenient for meeting the tension requirements. Utility Model Content

[0005] The purpose of the utility model is to provide an integrated carbon ribbon box to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Integrated ribbon cassette, including:

[0008] An end cover, wherein a supply end support rib is fixedly installed at one end of the inner lower surface of the end cover, and a recovery end support rib is fixedly installed at a position symmetrical to the supply end support rib on the inner lower surface of the end cover;

[0009] The ribbon holder is detachably connected to the inside of the end cap;

[0010] A plurality of hooks are arranged and fixedly installed on the inner surface of the end cover at equal intervals;

[0011] Two Teflon gaskets are arranged and symmetrically disposed inside the carbon ribbon holder.

[0012] Furthermore, a plurality of slots are equidistantly provided on the outer surface of the carbon ribbon holder, the hooks are movably engaged with adjacent slots, and a supply end positioning hole is fixedly provided on the upper end of the carbon ribbon holder.

[0013] Furthermore, a supply shaft is movably provided at one end of the carbon ribbon holder, and a recovery shaft is movably provided at the other end of the carbon ribbon holder.

[0014] Preferably, a carbon ribbon is rolled up at the outer sides of the supply shaft and the recovery shaft, and a consumable chip is bonded to the surface of one side of the carbon ribbon holder by glue.

[0015] Preferably, the upper ends of the recovery shaft and the supply shaft penetrate the adjacent Teflon gaskets and are rotatably connected to the carbon ribbon bracket.

[0016] Preferably: a supply end positioning column is fixedly installed at one end of the inner lower surface of the end cover, a recovery end positioning column is fixedly installed at the other end of the inner lower surface of the end cover, the other end of the supply shaft is rotatably sleeved on the outside of the supply end positioning column, and the other end of the recovery shaft is rotatably sleeved on the outside of the recovery end positioning column.

[0017] Preferably: the outer side of the supply end positioning column is located between the supply end support rib and the supply shaft, and a supply end spring is movably provided on the sleeve; the outer side of the recovery end positioning column is located between the recovery end support rib and the recovery shaft, and a recovery end spring is movably provided on the sleeve.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The design of the consumable chip approaching the hook helps to maintain the contact stability of the consumable chip. The carbon ribbon holder is designed with a supply end positioning hole. The raised shaft on the host can be used to assist the supply end of the carbon ribbon holder to maintain the parallelism of the supply end under high tension and prevent the carbon ribbon from wrinkling.

[0020] 2. By setting supply-end support ribs and recovery-end support ribs of different heights inside the end cover, springs of the same specification can obtain different pressures on the supply shaft and the recovery shaft, and the height of the supply-end support ribs is higher than that of the recovery-end support ribs, so that the pressure of the supply-end spring is greater, so that the supply shaft obtains greater pressure than the recovery shaft, which is converted into different carbon ribbon tensions, thereby making the supply end have greater tension than the recovery end. At the same time, springs with the same elastic force are used without distinguishing between the supply end and the recovery end, and the production process is simpler.

[0021] 3. By setting Teflon gaskets on the outer sides of the upper ends of the recovery shaft and the supply shaft, a smaller friction coefficient is provided to prevent jamming between the two during rotation and maintain normal winding of the carbon ribbon. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In this embodiment, the carbon ribbon holder 6 is buckled inside the end cover 1 by the hook 11 being stuck in the slot 17. The design of the consumable chip 7 being close to the hook 11 helps to maintain the contact stability of the consumable chip 7. The carbon ribbon holder 6 is designed with a supply end positioning hole 16.
