Description
Technical field
The utility model relates to the printing consumables field, particularly a kind of ribbon cartridge that is applied to such as the PRN devices such as mini-printer that use on the taxi.
Background technology
The black rumble class ribbon cartridge that is applied to PRN device such as mini-printer generally includes colour band core 1 ' that nylon makes and the box body 2 ' that is injection molded into, box body 2 ' is made up of drain pan 21 ' and lid 22 ', and this box body 2 ' has colour band core inlet 23 ', the outlet 24 ' of colour band core and colour band core transmission channel 25 '; Box body 2 ' inside is provided with band driving wheel 3 ', driven pulley 4 ', metal clips 5 ' and film 6 ', wherein, band driving wheel 3 ' or driven pulley 4 ' are provided with the black rumble that is used for going up China ink to colour band core 1 ', band driving wheel 3 ' and metal clips 5 ' are positioned near colour band core inlet 23 ' one side, driven pulley 4 ' is positioned near colour band core outlet 24 ' one side, and film 6 ' is positioned on the colour band core transmission channel of being with between driving wheel 3 ' and the driven pulley 4 ' 25 '.Metal clips 5 ' is pressed on colour band core 1 ' on the band driving wheel 3 ', when the printer driver axle drives this band driving wheel 3 ' and moves in the direction of the clock, locate to produce with colour band core 1 ' by colour band core inlet 23 ' the driving frictional force F ' that draws in the box body 2 ' at compacted position A ', thereby realize the circle transmission of colour band core 1 ', usually should drive frictional force F ' in the industry and be called into band power, general requirement is gone into band power and is the bigger the better; Film 6 ' presses colour band core 1 ' on a support column 7 ' of box body inside, the belt carcass 1 ' of checking colors produces a tension force f ', so that making the colour band core 1 ' that is positioned at print area tightens, this tension force f ' has determined colour band core 1 ' is pulled out by colour band core outlet 24 ' pulling force of box body 2 ', usually this pulling force is called band power in the industry, going out band power should be of moderate size.Printer goes out pin regularly by printhead, constantly impacts the tape base of colour band core, the printing ink on the colour band core is transferred to realized print procedure on the print media.
Going into band power and going out band power of the ribbon cartridge of said structure controlled respectively by metal clips 5 ' and 6 ' two parts of film.This type of ribbon cartridge is many because of assembly process, part is little, and workman's neglected loading phenomenon often appears in the finding as film 6 ', and the colour band core 1 ' that causes being positioned at print area can't be tightened and influence printing; Metal clips 5 ' has only one to press salient point because of the surface, also often has dress to fall and adorn anti-phenomenon to take place, and has had a strong impact on the quality of product, the matching requirements that improved product.These problems have brought very big hidden danger of quality for the processing of these black rumble class ribbon cartridges all the time.Once had several different methods to attempt going to address these problems, for example film color by transparent redness or the dark color of changing into, more eye-catchingly when making assembling improve the neglected loading problem, but effect is undesirable, can not thoroughly address the above problem.
