Description

Printer selenium drum

Technical Field

The invention belongs to the technical field of printer consumables, and particularly relates to a printer selenium drum.

Background

The laser printer selenium drum is also called a photosensitive drum. The base structure is generally composed of a base substrate made of aluminum, and a photosensitive material coated on the base substrate. The carbon powder in the printer selenium drum is the key for imaging in the printing process, the carbon powder is stored in the carbon powder bin in the printer selenium drum, but in the actual using process, after the printer selenium drum is not used for a period of time, the carbon powder can stand still in the carbon powder bin in the printer selenium drum to form a group, and therefore the problem that the carbon powder is not easy to feed is caused.

Disclosure of Invention

The invention aims to provide a toner cartridge of a printer, which solves the problem that carbon powder of the existing toner cartridge of the printer is difficult to feed.

The utility model provides a printer selenium drum, which comprises a housin, be equipped with charge roller, sensitization drum, developer roll in the casing, send whitewashed roller and carbon powder storehouse, the top of developer roll is equipped with the scraper, the scraper is fixed on the casing, the below of developer roll is equipped with useless powder box, be equipped with on the carbon powder storehouse and add the powder hole, it has sealed lid to add the powder jogged joint, the bottom in carbon powder storehouse is the elastic plate, be equipped with the pivot on the casing, rotate in the pivot and be connected with the cam, promote the elastic membrane when the cam rotates and reciprocate, be equipped with drive cam pivoted motor on the casing.

The working principle and the beneficial effects of the scheme are as follows: the carbon powder in the carbon powder bin is conveyed to the developing roller through the powder conveying roller and then is adhered to the surface of the developing roller, and the carbon powder on the developing roller is scraped uniformly by the scraper and then is adsorbed to the surface of the photosensitive drum for printing. When carbon powder just stews and conglobate in the carbon powder storehouse in printer selenium drum, start the pneumatic motor, the motor drives the cam and rotates, because the bottom in carbon powder storehouse is the elastic plate, can make the elastic plate upwards protruding deformation when the cam rotates to the carbon powder in the carbon powder storehouse of promotion cam top removes, when the cam rotated always, this part carbon powder can be fast along with the cam rotation and vibration from top to bottom, thereby makes the carbon powder dispersion of conglobation, and then the unloading work of being convenient for.

Furthermore, the cams are provided with a plurality of cams, and the cams are in transmission through a belt. Through the arrangement, the plurality of cams vibrate the carbon powder at different positions, so that the carbon powder dispersing speed is increased.

Furthermore, the shell is also provided with an elastic sheet, and the cam close to the elastic sheet stirs the elastic sheet when rotating. Through such setting, after the shell fragment was stirred downwards to the cam, the shell fragment made a round trip to vibrate, vibrated the striking to the elastic membrane, further accelerated the speed of carbon dust dispersion.

Further, the sealing cover comprises a cover body, a through hole is formed in the cover body, two sliding grooves are further formed in the cover body, the two sliding grooves are symmetrically arranged relative to the through hole, a sealing plate is connected to the sliding grooves in a sliding mode, an elastic piece is arranged between the sealing plate and the bottom of the sliding grooves, and the two sealing plates are in contact with each other to enable the through hole to be sealed when the elastic piece is in a natural state. Through such setting, when needing to add the powder, slide the closing plate to the spout, open the through-hole can, add the powder and finish the back and under the effect of elastic component the closing plate slides back and seal the through-hole.

Further, the elastic member is a compression spring. Through the arrangement, the compression spring is simple in structure, low in cost and convenient to install.

Furthermore, the through hole is connected with a guide pipe, a powder adding pipe is connected in the guide pipe in a sliding mode, the bottom of the powder adding pipe is in a conical shape, and an inclined plane is arranged on the upper surface of the sealing plate. Through the arrangement, the bottom of the powder adding pipe is in a conical shape, and the upper surface of the sealing plate is provided with the inclined surface, so that when the powder adding pipe slides downwards, the sealing plate is pushed into the sliding groove under the sliding of the inclined surface and the conical surface, the through hole is opened, and the powder adding work is simplified.

Drawings

FIG. 1 is a schematic structural diagram of a toner cartridge of a printer according to the present invention.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a shell 1, a charging roller 2, a photosensitive drum 3, a developing roller 4, a scraper 5, a powder feeding roller 6, a carbon powder bin 7, a cover body 8, a spring 9, a sealing plate 10, a powder adding pipe 11, a guide pipe 12, an elastic plate 13, an elastic sheet 14, a cam 15, a rotating shaft 16, a motor 17 and a waste powder box 18.

The embodiment is basically as shown in the attached figure 1: the utility model provides a printer selenium drum, which comprises a housin 1, be equipped with charge roller 2 in the casing 1, sensitization drum 3, developer roll 4, send powder roller 6 and carbon dust storehouse 7, developer roll 4's top is equipped with scraper 5, scraper 5 fixes on casing 1, developer roll 4's below is equipped with waste powder box 18, be equipped with the powder hole on the carbon dust storehouse 7, the powder hole connection has sealed lid, sealed lid includes lid 8, be equipped with the through-hole on the lid 8, still be equipped with two spouts on the lid 8, two spouts set up for the through-hole symmetry, sliding connection has closing plate 10 in the spout, be equipped with the elastic component between closing plate 10 and the spout bottom, and two closing plate 10 contacts so that the through-hole seals when the elastic component is under natural state, the through-hole connection has pipe 12, sliding connection has powder adding pipe 11 in pipe 12, the bottom that powder adding pipe 11 is the toper form.

The bottom in carbon powder storehouse 7 is elastic plate 13, is equipped with two pivot 16 on the casing 1, rotates on two pivot 16 and is connected with a cam 15, and two cams 15 are the symmetry and set up, through belt transmission between two cams 15, are equipped with drive cam 15 pivoted motor 17 on the casing 1, also through belt transmission between motor 17 and the cam 15, and casing 1 still is equipped with shell fragment 14, stirs shell fragment 14 when the cam 15 that is close to shell fragment 14 rotates.

The specific implementation process is as follows:

the carbon powder in the carbon powder bin 7 is sent to the developing roller 4 through the powder sending roller 6 and then is adhered to the surface of the developing roller 4, and the carbon powder on the developing roller 4 is evenly scraped by the scraper 5 and then is adsorbed to the surface of the photosensitive drum 3 for printing. When the carbon powder just stews and conglobate in the carbon powder storehouse 7 in the printer selenium drum, start gas motor 17, motor 17 drives cam 15 and rotates, because the bottom in carbon powder storehouse 7 is elastic plate 13, can make elastic plate 13 upwards protruding deformation when cam 15 rotates, thereby promote the carbon powder in the carbon powder storehouse 7 of cam 15 top to remove, when cam 15 rotates always, this part carbon powder can rotate along with cam 15 fast and vibration from top to bottom, thereby make the carbon powder dispersion of conglobation, and then the unloading work of being convenient for. In addition, the powder adding pipe 11 slides downwards, the sealing plate 10 is pushed into the sliding groove under the sliding of the inclined surface and the conical surface, so that the through hole is opened for powder adding work, and the sealing plate 10 slides back under the action of the elastic piece to seal the through hole after the powder adding is finished.
