Abstract
The utility model relates to a closed printing-machine ribbon cartridge, which belongs to the technical field of a printing apparatus. The utility model is formed by the improvement on the basis of the existing ink-ribbon cartridge. The utility model has the essential point that a drive wheel, a driven wheel and an ink wheel of an ink supply and strap feeding mechanism are plastic gears, the tooth tops of which form a round arc shape; the ink supply and strap feeding mechanism is directly engaged and driven. The ink wheel is arranged on an elastic support frame. When the utility model is operated, the ink wheel and the driven wheel automatically engage. When the utility model is not operated, the ink wheel and the driving wheel are separated. The ventilation hole, the ink pouring hole and the ink guide hole on an ink storage cartridge are all provided with a guide tube; the guide tubes extend to the ink storage cartridge. The ribbon cartridge has the advantages of even and stable ink supply, good anti-environment jamming and anti-leakage performance, beautiful appearance and easy production and manufacture.
Description
The utility model relates to typewriting, the used ribbon cartridges of printer such as four-way, microcomputer, belongs to the PRN device technical field.
The existing printer ribbon cartridge, comprise the accumulator on the China ink band in upper box cover, lower box body, the box chamber, last black tape-feed and the lid, go up black tape-feed and generally be by driving wheel, driven pulley, China ink wheel and belt are set, the transmission by belt drives that colour band advances and be coated with China ink on tape base.Accumulator is arranged on the lid, and outer cover is topped to connect and compose an integral body with the hot box of lid on accumulator.Accumulator is provided with Chu Moti in the chamber, and pre-oiling China ink is coated onto printing ink on the tape base through China ink wheel, belt etc. by ink-guiding body from accumulator again.For example, number of patent application is that 89217972.4 " the China ink band feeder of printer and printer " and the patent No. are 95240402.8 " ink ribbon cartridge for printer " or the like.People are for the seepage of the accumulator that prevents ribbon cartridge, improve the stability of ink supply, reduce the wearing and tearing of colour band, improve print quality, prolong the service life of ink ribbon cartridge for printer, improve though carried out many research, but still fail the effect that obtains to envision, in various degree exist seepage, the ink supply instability, influence print quality, ribbon cartridge is short service life, wasting phenomenon.
The purpose of this utility model is that a kind of black tape-feed advantages of simple that will be provided, and antiseep, water clock are good, and ink supply is stable, the closed ink ribbon cartridge for printer of long service life.
The purpose of this utility model is to form by the improvement to existing ink ribbon cartridge for printer: closed ink ribbon cartridge for printer comprises box body, storage print cartridge on China ink band in lid and the box chamber, last black tape-feed and the lid, the driving wheel, driven pulley, the China ink wheel that it is characterized in that black tape-feed are the direct geared engaged transmission, the China ink wheel is arranged on the elastic support, and black wheel shaft two ends are through in the shifting chute that is provided with on box body and the lid.Storage print cartridge box wall wall is provided with passage and pouring ink hole, storage print cartridge box body middle part is provided with obturator, storage print cartridge lid is provided with ink-guiding hole, cartridge body connects with the ink box cover heat seal, passage, pouring ink hole are provided with the conduit that stretches in the cavity of ink storage box, ink-guiding hole is provided with and stretches to the inside and outside ink guide tube of cavity of ink storage box, is provided with porous in the cavity of ink storage box and stores up black body, is provided with and stores up the contacted ink-guiding body of black body in the ink guide tube.Said driving wheel, driven pulley, China ink wheel are circular-arc plastic gear for tooth top.Elastic support comprises support, and carrier base, spring, support and carrier base adopt chute to peg graft, and spring is arranged between support and the carrier base, and support is provided with the socket that the China ink wheel is installed.When driving driven pulley of the driving wheel in the last black tape-feed and the rotation of drive China ink wheel, the spring pressurized of elastic support, China ink are taken turns with driven pulley and are close to, and printing ink is delivered on the driven pulley from the China ink wheel, is coated onto China ink by driven pulley again and is with.When last black tape-feed quit work, the China ink wheel was thrown off with driven pulley under the effect of spring, avoids printing ink to be seeped on the driven pulley when printer is not worked, and polluted the China ink band.In order to make ribbon cartridge when the transportation neutralization quits work, ink-guiding body in the ink guide tube of storage print cartridge separates with the China ink wheel, avoid continuing to China ink wheel ink bleed because of contact makes printing ink, produce and pollute and seepage, the storage print cartridge is arranged in the loose slot on the lid, one end of loose slot is provided with spring and withstands the storage print cartridge, and the other end sidewall wall of loose slot is provided with the spacing pin hole of storage print cartridge that ink-guiding body and China ink wheel are thrown off.The storage print cartridge is advanced to the end that spring is set, latch is inserted in the jack withstand the storage print cartridge and reset, ink-guiding body is taken turns with China ink separate.Passage, pouring ink hole and ink-guiding hole on the storage print cartridge all is provided with one section conduit that stretches in the cavity of ink storage box, and when being in its lowermost position, the printing ink of pre-storage can not come out from the Kong Guanzhong spill and leakage yet in the cavity of ink storage box.
The utility model is rational in infrastructure simple, manufactures easily, and storage print cartridge antiseep is good, goes up black tape-feed running steadily, is coated with China ink evenly, and printing effect is good, can prolong the service life of ribbon cartridge.
