Description
Technical Field
[0001] The utility model relates to the technical field of carbon ribbon boxes, in particular to an automatic deviation-correcting carbon ribbon box. Background Art
[0002] Thermal transfer technology uses a specialized carbon ribbon to transfer a toner coating onto paper or other materials. This technology has high adhesion and can protect the printed content from external influences. Thermal transfer printers are widely used in multiple industries due to their high clarity, adaptability to a variety of materials, high weather resistance, diverse application scenarios, high efficiency, and stability. This device is the carbon ribbon cartridge used in thermal transfer printers. Carbon ribbon is a traditional printing consumable used in typewriters and fax machines. It usually consists of a text device, a carbon ribbon device, and a paper feed mechanism. During the printing process, the print is rubbed against the carbon ribbon, and then text and graphics are printed on the paper.
[0003] Thermal transfer printers all use a rubber roller to press the printing material onto the thermal sheet to print. The rubber roller rotates to transport the printing material. One end of the rubber roller is connected to the prime mover through a transmission element. Therefore, the force on both ends of the rubber roller is inconsistent, causing the transported printing material to be skewed.
[0004] Therefore, a carbon ribbon cassette with automatic deviation correction is needed to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a carbon ribbon cassette with automatic deflection correction, so as to solve the problem of deflection of consumables during the transmission process proposed in the above background technology.

[0007] Preferably, a paper roll is installed on the right side of the inner side of the lower cover of the consumable box, and a paper roll body is provided on the outer side of the paper roll.
[0008] Preferably, a carbon ribbon shaft is installed on the left side of the inner portion of the lower cover of the consumable box, and a carbon ribbon body is provided on the outer side of the carbon ribbon shaft.
[0009] Preferably, a guide column is fixed to the rear end of the lower cover of the consumable box.
[0010] Preferably, a docking rod is fixed to the bottom end of the upper cover of the consumable box, and a docking seat is fixed to the inner side wall of the lower cover of the consumable box.
[0011] Preferably, the bottom end of the docking rod extends to the interior of the docking seat.
[0012] Preferably, a thermal sheet is provided on the left side of the lower cover of the consumable box, a rubber roller is provided on the left side of the thermal sheet, and a prime mover is installed at the bottom end of the rubber roller.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: by providing a consumables box outlet and a clamping position, the consumables box outlet is composed of an upper wall surface and a lower wall surface, the lower wall surface is provided with a cutout, and the consumables box upper cover is provided with a wedge-shaped block. When the consumables box upper cover and the consumables box lower cover are closed, the oblique mouth of the wedge-shaped block abuts against the mouth of the lower wall surface and presses the lower wall surface toward the inner side of the consumables box outlet, so that the lower wall surface is inclined toward the inner side of the consumables box outlet, forming a reverse inclined surface. When the paper roll body and the carbon ribbon body pass through the consumables box outlet, When the filament box is opened, it is subjected to the reaction force of the reverse slope of the lower wall. At the same time, the rubber roller and the thermal sheet press the paper roll body and the carbon ribbon body between the outlet of the filament box and the card position. When printing, one end of the rubber roller is driven by the prime mover and continuously pulls the paper roll body and the carbon ribbon body out of the lower cover of the filament box. The power end of the rubber roller transmits a greater force than the non-power end, and the reverse slope of the lower wall of the filament box outlet just offsets the reaction force of the filament, thereby solving the problem of filament deflection.
[0014] By providing a paper roll shaft, a carbon ribbon shaft and a guide column, the paper roll shaft and the carbon ribbon shaft are provided in the lower cover of the consumable box, which are used to install the paper roll body and the carbon ribbon body respectively. After the paper roll body and the carbon ribbon body are attached to each other through the guide column, they can be extended from the outlet of the consumable box, realizing the auxiliary limit function when the carbon ribbon box is used;
[0015] By providing a rubber roller and a prime mover, the prime mover is used to drive the rubber roller. When the prime mover is started, the rubber roller can be driven to rotate. The rubber roller is driven by the prime mover to continuously pull the paper roll body and the carbon ribbon body out of the lower cover of the consumable box, thereby realizing the portability of the carbon ribbon box when used.
