Abstract

The invention provides a carbon powder feeding device of a laser printer and a laser duplicating all-in-one machine and an application method of the carbon powder feeding device, belongs to accessories of printing and duplicating machines, and is especially applicable to feeding powder to a carbon powder box of the laser printer and the duplicating machine or the all-in-one machine. According to the carbon powder feeding device, the structure of the carbon powder box is improved, a special powder feeding device is additionally arranged, and powder feeding holes and discharge holes are mainly formed in two edges of the carbon powder box; the powder feeding holes and the discharge holes are sealed by seals; a work drum and a dust collecting bag full of carbon powder are also arranged; an opening of the dust collecting bag is matched with the discharge holes. The device provided by the invention is simple, convenient to operate, reliable, and free of carbon powder escape when the carbon powder is fed, does not pollute air, and does not damage human health.

Description

A kind of laser printer and laser, duplicating all-in-one add carbon powder device and using method

Technical field

A kind of laser printer that the present invention proposes and laser, duplicating all-in-one add carbon powder device and user's printing owned by France, duplicating machine annex, be especially suitable for the cartridge of laser printer and duplicating machine or all-in-one to add powder.

Background technology

Printer and duplicating machine or all-in-one are the modern major equipments of office, for printing, duplicate the data such as word, figure, drawing, certificate, advertisement and publicity, the kind of printing, duplicate is a lot, laser printing, copy application are more general, and the whole process of optical printer work can be described as charging, exposure, video picture, image rotation, photographic fixing, removing and the circulation except seven large steps such as looking like.Whole laser printing flow process is launched by " charging " action, first in photosensitive drums, be full of negative charge or positive charge, in print control unit, raster bitmap view data is converted to the laser beam information of laser scanner, by reflecting prism to photosensitive drums " exposure ", photosensitive drum surface just formed represent with positive charge with the identical image information of print image, then adsorb the carbon powder particle in cartridge, formed the carbon dust image of photosensitive drum surface.And printer paper is full of negative charge by a charhing unit before contacting with photosensitive drums, in the time that printer paper is passed by photosensitive drums, because positive and negative charge attracts each other, the carbon dust image of photosensitive drums is just transferred on printer paper.Make carbon powder particle completely and paper fibre absorption through overheated transfer printing unit heating, formed print image.Then by carbon dust residual in photosensitive drums " removing ", last action is " except picture ", namely removes static, makes the current potential of photosensitive drum surface be returned to original state, to launch next do action.

When printing, duplicating, need carbon dust, carbon dust is sealed in cartridge, after carbon dust in cartridge is finished, duplicate if continue, there are two kinds of ways to obtain carbon dust, the one, change a new cartridge that has carbon dust, the second is that carbon dust is added to former cartridge, included in the carbon dust 50-200ml of the cartridge of different model.Cartridge is the exquisite sealing capsule that its periphery has been installed toner cartridge and other part, add powder, first unload toner cartridge and other part, open carbon dust lid, clear clean cartridge inside and the useless carbon dust of removing, then carefully install new carbon dust additional, then, then toner cartridge and other part again, also to clean cartridge, this process, carbon dust can fly upward, and pollutes periphery and is sucked by people.Carbon dust is a kind of very harmful material to the person, carbon dust principal ingredient is: F-Fe3O4 crystal powder: account for 20%-30%, polyacrylate-styrol copolymer: account for 50%-60% charge adjusting agent: account for 10%-20%, the surface modification machine polyethylene/polypropylene paraffin such as flowing agent SIO2.Carbon dust has eight large technical indexs; wherein the granularity volume distributed median index of carbon dust is: 5-20 micron; so little particle; be easy to be suspended in the air and sucked by people; after human body multiple-contact sucks; carcinogenic probability will exceed 10% left and right than normal person; and after surface modifier polyethylene/polypropylene paraffin is inhaled in body; its little molecule particle can be absorbed in blood circulation system; finally by vegetation in kidney; extremely be difficult for being discharged from (the insoluble and water because of carbon dust), will exceed 3 times thereby bring out the probability of the illnesss such as kidney stone than normal person.Because carbon dust is harmful, and the existing process that adds carbon dust can not avoid producing carbon dust and fly upward, so, change the existing present situation that adds carbon dust necessary.

Summary of the invention

A kind of laser printer that the present invention proposes and laser, duplicating all-in-one add carbon powder device and using method, be in the process that adds carbon dust, carbon dust can not enter air, guarantees personnel's health.

For this reason, improved the structure of cartridge and increased special powder adding device.

Laser printer and laser, duplicating all-in-one add a carbon powder device, contain cartridge and carbon dust, it is characterized in that described cartridge has flour feeding hole and powder outlet, flour feeding hole and powder outlet have sealing sealing; Syringe, the collection flour bag of having filled in addition carbon dust, the sack of collection flour bag mates with powder outlet.

Above-mentioned a kind of laser printer and laser, duplicating all-in-one add carbon powder device, it is characterized in that described flour feeding hole can perforate on the both sides of the relative two sides of cartridge or the same face with powder outlet.

The above a kind of laser printer and laser, duplicating all-in-one add carbon powder device, it is characterized in that described flour feeding hole and the sealing of powder outlet are plug or abrasive paper.

A kind of laser printer and laser, duplicating all-in-one add carbon powder device and using method is:

1, collect useless carbon dust

Remove the sealing of powder outlet, the sack of collection flour bag, to connecting powder outlet, is scavenged into collection flour bag completely the carbon dust in cartridge, then, and with sealing good seal powder outlet;

2, carbon dust is added to cartridge

Remove the sealing of flour feeding hole, the carbon dust in syringe is advanced in cartridge, then, with sealing good seal flour feeding hole.

Device of the present invention is simple, easy to operate, reliable, while installing carbon dust additional, overflows without carbon dust, and not contaminated air, is not detrimental to health.

Accompanying drawing explanation

Fig. 1 is the front view of carbon powder device;

Fig. 2 syringe figure;

Fig. 3 is the constitutional diagram of syringe while adding carbon dust

Fig. 4 is the constitutional diagram while collecting useless carbon dust.

Embodiment

By a specific embodiment explanation the technical program, Fig. 1-4 have shown the structure and the using method that add carbon powder device

Add carbon powder device and be made up of cartridge 1, syringe 5, collection flour bag 4 and carbon dust 6, it is characterized in that described cartridge has flour feeding hole 3 and powder outlet 2, flour feeding hole and powder outlet have sealing sealing 7; Syringe 5, the collection flour bag 4 of having filled in addition carbon dust 6, the sack of collection flour bag mates with powder outlet.When use, first collect useless carbon dust, the sealing 7 of removing powder outlet, the sack of collection flour bag 4, to connecting powder outlet 2, is scavenged into collection flour bag completely the useless carbon dust in cartridge, then, with sealing 7 good seal powder outlets 2.Remove after useless carbon dust, just carbon dust can be added to cartridge, first remove the sealing of flour feeding hole 3, the carbon dust 6 in syringe 5 is advanced in cartridge, then, with sealing 7 good seal flour feeding holes.
