Description

A kind of new middling speed compounding machine developer agitating roller

Technical field

Office equipment accessory technical field is the utility model is related to, more particularly to a kind of new middling speed compounding machine developer stirs Mix roller.

Background technology

Ricoh's Series Digital compounding machine, is Ricoh's new generation product, and printing effect is good, because cost is cheap, generally 30% or so of other equal models, therefore possess extraordinary cost performance, it is adapted to vast medium and small office equipment outsourcing enterprise.

Ricoh's Series Digital compounding machine toning system is divided into：Toner cartridge, cleaning, development, magnetic roller, gear train, agitating roller etc. 6 Big unit.Toner cartridge and cleaning unit mainly provide word print service, and developing cell is to provide carbon dust conveying and effect is realized, magnetic The effect of roller unit is to realize to supply the carbon dust of toner cartridge, and gear train unit is magnetic roller, three toner cartridge, agitating roller units provide Power transmission, on the one hand the effect of agitating roller is carbon dust can be uniformly transported in magnetic roller, and the opposing party interviews to be added new Carbon dust fully mixes with carrier and allows carbon dust that electrostatic occurs and react, carrier is with magnetic iron powder.

The influence of stirring roller unit air exercise print effect is very crucial, and existing agitating roller is two unidirectional wide spirals Bar, therefore during agitating roller rotates, carrier and carbon dust can convey towards same direction with spiral, when carrier and carbon After powder is transported to the end of screw rod, the screw rod of opposite side can reversely convey carrier and carbon dust, so as to realize carrier and carbon Shuttling movement of the powder in the casket that develops, is thoroughly mixed.

, can be close in development casket when carrying out high-volume running hours, carrier and carbon dust due to being conveyed always to gear end Gear unit side forms accumulation, therefore the sealing of gear unit is easily ruptured by larger pressure, causes carrier and carbon dust to be let out Reveal in gearcase, hard carrier and plastic gear occur friction and cause gear to be disintegrated rapidly, ultimately result in gear failure, multiple Conjunction machine can not continue to supplement carbon dust, and the carbon dust in the casket that develops lacks machine alarm and is stopped.

The content of the invention

To solve above-mentioned problem of the prior art, the utility model provides a kind of new middling speed compounding machine developer agitating Roller, in the end of screw rod, the good reverse plastic spiral of increase wearability, assist to be transported to the carrier of end and carbon dust is quickly defeated It is sent in the reverse acting spiral bar of opposite side, increases carrier and carbon dust circulation rate, reduces the pressure of carrier and carbon dust to gear unit Power and the accumulation in development casket end.
