Description
Technical Field
[0001] The utility model relates to the technical field of ribbon racks, in particular to a printer ribbon rack. Background Art
[0002] The ribbon holder and the ribbon cassette are the same concept. They both refer to containers for fixing ribbons, which are specially used in dot matrix printers. The ribbon is installed on the ribbon holder, which is fixed on the printer to provide ink when printing. This device is very common in dot matrix printers, because the printing principle of dot matrix printers is to pierce the ribbon with a needle on the print head to leave an imprint on the paper, thereby realizing the printing function. The quality of the ribbon directly affects the effect and quality of printing. The ribbon is usually made of nylon braided fabric soaked and dyed with ink, and the ribbon holder or ribbon cassette provides a structure for installing and fixing these ribbons. When replacing the ribbon, usually only the ribbon itself needs to be replaced, while the ribbon holder or ribbon cassette can be reused, and the new ribbon only needs to be inserted into the original ribbon holder. This design not only reduces the cost of use, but also improves environmental protection, because users do not have to buy a brand new ribbon holder every time, thus reducing waste.
[0003] The ribbon is then manually straightened and passed through the bottom of the ribbon cassette. After the ribbon passes through the bottom, it is also necessary to pass it between two gears, and the meshing rotation of the two gears is used to move the ribbon, so as to facilitate normal use with the needle of the printer. The ribbons used in conjunction with the traditional ribbon cassette are all connected end to end to form a loop. If the ribbon slips or gets tangled during use, the ribbon cassette needs to be disassembled and readjusted. At this time, since there is no boundary between the used and unused parts of the ribbon inside, it is not convenient to straighten the ribbon, and the ribbon is transmitted under the rotation of the gears. The ribbon is not subjected to a certain resistance during this process, which makes the ribbon easy to become loose during use, resulting in overlapping shadows during printing, which is inconvenient for actual use.

The ribbon body 4 and the winding reel 13 can be rotated by the rotating shaft, and the two winding reels 13 can rotate synchronously under the winding of the ribbon body 4, so the wound ribbon body 4 can be unwound step by step, which is convenient for use and further reduces the disorder of the ribbon body 4. When the extrusion mechanism is in use, when the ribbon body 4 is installed, the ribbon body 4 needs to be located on the top of the connecting plate 12. At this time, the handle 8 is held by hand and forced upward, so that the handle 8 drives the connecting rod 9 and the pressure plate 11 to move upward. At this time, the first spring 10 will be compressed. After the pressure plate 11 moves upward, the ribbon body 4 can be placed on the connecting plate 12, and then the handle 8 is released. Under the action of the first spring 10, the pressure plate 11 can squeeze the ribbon body 4, so that the ribbon body 4 The ribbon body 4 is squeezed on the connecting plate 12, wherein the ribbon body 4 can still slide after being squeezed, but a large force needs to be applied to the sliding of the ribbon body 4, so that when the first gear 6 and the second gear 7 transmit the ribbon body 4, the ribbon body 4, which is working at the bottom, can be in a tensioned state, which is convenient for use. The first gear 6 and the second gear 7 are both installed in the ribbon box 1. The traditional installation method is that one gear is directly connected to the ribbon box 1 for rotation, and the other gear needs to be detachably connected to the ribbon box 1 for rotation. Therefore, when the ribbon body 4 is installed, the gear is removed, and then the ribbon body 4 is placed between the two gears, and finally the gear is installed. In order to improve the convenience of installation, the first gear 6 is connected to the ribbon box 1 for rotation.The second gear 7 and the slider 17 are rotatably connected. The slider 17 can be pulled downward by the pull ring 20 and the vertical rod 19, so that the second gear 7 is away from the first gear 6, so as to facilitate the placement of the ribbon body 4 between the first gear 6 and the second gear 7. Then, the pull ring 20 is released, and under the action of the second spring 18, the slider 17 moves upward, driving the second gear 7 to move upward synchronously, so that the second gear 7 and the first gear 6 are meshed again, and the ribbon body 4 is located between the first gear 6 and the second gear 7. This installation method can avoid the situation where the second gear 7 is disassembled, which causes the installation of the second gear 7 to be cumbersome or the second gear 7 is lost. The three guide wheels 5 can guide the ribbon. The baffle 21 can block the used ribbon body 4 transmitted by the first gear 6 and the second gear 7, so as to reduce the phenomenon that the ribbon body 4 is entangled again during the rotation of the first gear 6 and the second gear 7, causing the ribbon body 4 to be disordered.
