Description

Meticulous powder feeding machine
Technical field
The utility model relates to laser printer carbon powder box employed specialized equipment in the printing test process, especially a kind ofly can accurately control the meticulous powder feeding machine that adds the powder amount to the magnetic roller.
Background technology
The laser printer carbon powder box must print test to each product before product export, come the cartridge product is carried out quality testing and judgement by printing effect.Because the toner strip of paper used for sealing of cartridge can not break a seal before the user uses once sealing, therefore, can not use the carbon dust that is sealed in the toner to print test.
The way of existing printing test is: 1. cartridge is assembled into developing device and drum assembly two large divisions; 2. after adding the capacity carbon dust that printing test uses toward magnetic roller place developing device and drum assembly two parts are fitted together; 3. promptly be engraved in after assembling is finished and carry out actual printing test on the laser printer; 4. after the test passes, the developing device and the drum assembly of laser powder box are taken apart again, respectively the surplus powder of test toner in two parts is removed, particularly the magnetic roller segment of developing device also must be pulled down the magnetic roller, and magnetic roller and developing chamber are aspirated surplus powder; 5. surplus powder is reinstalled the magnetic roller after removing, and again developing device and drum assembly two parts is fitted together, and packing is dispatched from the factory at last.
Above method operation is very complicated, repeated disassembled and assembled again after cartridge detects, and the end product quality to the laser printer carbon powder box exerts an influence easily.
At the problems referred to above, utilize the principle of work of laser printer, the applicant invents a kind of new printing test method: make on charging roller, the photosensitive drums not charged, the magnetic force that the negative high voltage that produces by electric wiring makes carbon dust overcome the magnetic roller is transferred on the photosensitive drums, when printer moves, the unnecessary carbon dust scraper income waste powder hopper that all is cleaned has reached the requirement of photosensitive member drum nothing left powder in the cartridge.
The utility model just provides the above-mentioned method of testing of a kind of employing, can accurately control the specialized equipment that adds the powder amount to the magnetic roller.
Summary of the invention
The purpose of this utility model provides a kind ofly can accurately control the meticulous powder feeding machine that adds the powder amount to the magnetic roller.
For achieving the above object, the utility model provides following technical scheme: meticulous powder feeding machine comprises
Pedestal and be fixed in the powder bucket of pedestal top;
Described powder bucket below is provided with cassette holder;
Wherein,

The meticulous powder feeding machine of the utility model is transported to the carbon dust in the powder bucket on the magnetic roller by measuring tank, can accurately control the powder amount of carrying to the magnetic roller by the size of control measuring tank volume.Driven unit drives spool Rotate 180 degree at every turn, and when measuring tank departs from the strip passage of powder bucket, the outside surface of spool will seal the strip passage, and the carbon dust in the powder bucket can not flow out.In addition, seal between the inwall of valve portion and the spool outer wall, make that the carbon dust in the measuring tank can not leak between valve portion inwall and the spool in rotary course.The carbon dust that adds when control cartridge developing device and the assembling of drum assembly on the left magnetic roller adds the powder amount in 1～5 gram (being preferably the 2-3 gram), the micro-carbon dust that enters so in the laser printer powder box waste powder hopper will not produce any influence to product export and use, thereby needn't tear box open, inhale surplus powder, re-assembly again, not only save operation but also fully guaranteed the outgoing behind the product printing test.
For realizing better technique effect, the meticulous powder feeding machine of the utility model further comprises following technical characterictic:
Also comprise shaft, this shaft along self axial wobble, is equipped with stirring vane by cylinder or driven by motor on the shaft, and the part of shaft and stirring vane are positioned at described powder storehouse.
Increase is to the stirring of carbon dust in the powder bucket, keeps when making carbon dust be lowered to measuring tank evenly, and the carbon dust amount of guaranteeing at every turn to put into measuring tank is basic identical.
Also comprise and be fixed on the pedestal, be used for driving and wait to add powder cartridge magnetic roller motor rotating.
Increase to drive and wait to add powder cartridge magnetic roller motor rotating, the magnetic roller that drives cartridge rotates the carbon dust that can make on the magnetic roller and distributes more even.
Described poppet shaft to the end connect a rotary cylinder.
Use the rotary cylinder driving to add the rotation of powder axle and realize that it is more prone to.
Described cassette holder is arranged on the described pedestal movably along described base plane, and is connected with a promotion cylinder.
Cassette holder can move horizontally conveniently to be waited to add putting into of powder cartridge, saves the volume of whole meticulous powder feeding machine.
The volume of described measuring tank is identical with 2-3 gram carbon dust volume.
The Sheng Fenliang of measuring tank is best at 2-3 gram, if Sheng Fenliang very little print paper very little, may not reach the test effect, if Sheng Fenliang is too much then be unfavorable for follow-up cleaning to cartridge.
