Description

Technical Field

[0001] The utility model relates to the technical field of selenium drums, and more specifically to a moisture-proof selenium drum toner box. Background Art

[0002] Carbon powder, also known as toner, is a powdered substance used in laser printers to form images on paper. Black toner is composed of binder resin, carbon black, charge control agent and external additives. The toner cartridge is the core component of the printer, and the toner cartridge is the component used to hold toner.

[0003] The Chinese patent with the authorization announcement number CN218601685U is a moisture-proof toner cartridge, comprising a toner cartridge and a motor. The toner cartridge is provided with a photosensitive drum, a magnetic roller and a charging roller. The toner cartridge also comprises a cartridge body, the cartridge body being mounted on the toner cartridge, and the cartridge body having a cavity inside. This application achieves the closure of the discharge port when not in operation by adopting the coordinated arrangement of a metal intercepting plate and an electromagnet, thereby enhancing the sealing performance of the cartridge body and preventing water vapor from entering the cartridge body, thereby playing a moisture-proof role. Subsequently, by adopting the design of a drying tube, the water vapor inside the cartridge body is adsorbed by the desiccant inside the drying tube, thereby reducing the water vapor content inside the cartridge body and preventing the carbon powder from condensing into agglomerates. This improves the moisture-proof performance of the toner cartridge, making it difficult for water to enter and become damp in the cavity, thereby ensuring that no damp carbon powder enters the toner cartridge and causes damage to the cartridge. Although the toner cartridge is provided with a flow limiting plate to limit the flow of toner at the discharge port, the design uses a torsion spring to drive the metal intercepting plate to close the discharge port. Since the flow of toner out of the flow limiting plate is fixed, when closed, the toner on the metal intercepting plate is easily stuck between the metal intercepting plate and the cartridge body, resulting in reduced sealing. External moisture can easily enter the interior of the cartridge body through the gap between the metal intercepting plate and the cartridge body, reducing the moisture-proof effect of the toner cartridge. When the toner cartridge is laid down for use, the transmission rod and the protrusion stir the toner, and the toner is lifted up and enters the drying tube, which will cause the toner to adhere to the desiccant in the drying tube, affecting the dehumidification function of the desiccant.

[0027] The moisture-proof structure includes a fixed box 12, a guide rail 1202, a compression spring 22, a bottom plate 23, a rotating drum 24, a connecting drum 25, an installation drum 26, a desiccant bag 27 and a cover plate 28. The top of the toner cartridge 8 is symmetrically provided with a placement hole connected to the fixed box 12. The fixed box 12 is flush with the top of the toner cartridge 8. A pressing groove is provided on the top of the fixed box 12. The bottom of the pressing groove is elastically connected to the bottom plate 23 through a compression spring 22. The top of the bottom plate 23 is rotatably installed with the rotating drum 24. The outer array of the rotating drum 24 is installed with a slider 2401. The guide rail 1202 is installed at the lower end of the pressing groove and is slidably sleeved on the outer side of the rotating drum 24. The bottom of the guide rail 1202 is provided with a guide groove slidably connected to the slider 2401. The top of the slider 2401 is provided with an inclined surface 1. The bottom of the guide rail 1202 is also provided with an inclined surface connected to the inclined surface. The top of the rotating cylinder 24 is provided with a connecting cylinder 25, and the top of the connecting cylinder 25 is provided with a mounting cylinder 26 with a top opening. A desiccant bag 27 is placed inside the mounting cylinder 26. The top of the outer end of the mounting cylinder 26 is threadedly connected to a cover plate 28. A sealing ring 2 is provided on the side where the cover plate 28 and the mounting cylinder 26 are in contact. The gap between the cover plate 28 and the mounting cylinder 26 is closed by the sealing ring 2. When the inclined surface 1 of the slider 2401 is located in the slot of the guide rail 1202, the compression spring 22 is in a partially semi-compressed state. At this time, the through hole of the mounting cylinder 26 and the fixed box 12 is connected. When the slider 2401 is located in the guide groove of the guide rail 1202, the compression spring 22 is in an expanded state. At this time, the through hole of the mounting cylinder 26 and the fixed box 12 are not connected, and the connecting cylinder 25 closes the through hole of the fixed box 12.

[0028] Both ends of the mounting cylinder 26 and the fixed box 12 are provided with through holes, and a filter screen 1201 is embedded in the through hole of the fixed box 12. The mesh of the filter screen 1201 is smaller than the diameter of the carbon powder, which plays a role in filtering the carbon powder. The two ends of the fixed box 12 are slidably connected with a slide plate 13. The upper end of the slide plate 13 is provided with a connecting hole adapted to the size of the through hole. A plurality of scrapers are equidistantly installed inside the connecting hole. The scraper is slidably connected to the filter screen 1201, and the filter screen 1201 is cleaned by sliding the scraper up and down. The end of the scraper away from the filter screen 1201 is tilted downward, which reduces the friction resistance between the scraper and the carbon powder and prevents the carbon powder from staying on the scraper. The bottom of 13 is provided with a second inclined surface that slides against the stirring blade 11. The stirring blade 11 is in a M shape. A limit block 1301 is installed at one end of the skateboard 13. Both ends of the fixed box 12 are provided with connecting grooves that are slidably connected to the limit block 1301. The top of the connecting groove is slidably connected to the top of the limit block 1301 through a buffer spring 21. When the stirring blade 11 contacts the second inclined surface of the skateboard 13, the skateboard 13 is pushed upward, and the limit block 1301 squeezes the buffer spring 21. When the stirring blade 11 is out of contact with the second inclined surface of the skateboard 13, the thrust of the buffer spring 21 drives the limit block 1301 and the skateboard 13 to slide downward, causing the skateboard 13 to slide up and down.

[0029] Working principle: When in use, put the whole into the printer. When the printer is started, the electromagnet 20 is energized, and the metal plate 19 slides due to the suction of the electromagnet 20. When the metal plate 19 slides, it drives the diverter plate 2 15 to slide. When the diverter plate 2 15 slides, the diverter hole on the diverter plate 2 15 gradually approaches the diverter hole of the diverter plate 1 14. At the same time, the diverter plate 2 15 stretches the limit spring 18 to gradually increase the flow rate of toner in the diverter hole. The toner flows out of the diverter hole and falls on the sponge roller 7. At the same time, the motor 2 drives the photosensitive drum 4 to rotate, and drives the charging roller 5, the developing roller 6, the sponge roller 7 and the idler wheel 3 to rotate in turn through the driving gear at one end. When the sponge roller 7 rotates, it drives the toner on the developing roller 6. The toner on the developing roller 6 adheres to the charging roller 5, and the charging roller 5 drives the toner to adhere to The photosensitive drum 4 is placed on the photosensitive drum 4, and a layer of charge is attached to the surface of the photosensitive drum 4. With the cooperation of the laser and the transfer roller in the printer, imaging is achieved on the paper. The idler wheel 3 drives the two rollers 10 to rotate through the spur gear 9. The roller 10 drives the stirring blade 11 to stir the toner. The dust raised by the toner during stirring is filtered through the filter 1201 to prevent the toner from entering the through hole of the mounting cylinder 26 and the fixed box 12 and adhering to the desiccant bag 27. When the stirring blade 11 rotates, it contacts the second inclined surface at the bottom of the slide plate 13. The slide plate 13 is squeezed and slides upward, driving the limit block 1301 to slide upward when sliding. The limit block 1301 squeezes the buffer spring 21. When the stirring blade 11 is out of contact with the second inclined surface of the slide plate 13, the thrust of the buffer spring 21 drives the limit block 1301 and the slide plate 13 Slide downward to make the slide plate 13 slide up and down. When the slide plate 13 slides up and down, it drives the scraper to slide up and down to clean the surface of the filter 1201 to prevent carbon powder from adhering to the surface of the filter 1201 and causing the mesh of the filter 1201 to be blocked. When adding carbon powder, when the electromagnet 20 is not energized, the metal plate 19 is not subjected to suction. At this time, the diverter plate 15 slides in the opposite direction due to the rebound force of the limiting spring 18, so as to gradually close the diverter hole. Loosen the pipe cover and add carbon powder to the carbon powder box 8 through the feed pipe 801. After adding, tighten the pipe cover again. When not in use, the moisture inside the carbon powder box 8 is adsorbed by the desiccant bag 27 to prevent the carbon powder from condensing into agglomerates. When replacing the desiccant bag 27, press the cover plate 28, which drives the installation cylinder 26, the connecting cylinder 25, the rotating cylinder 24, and the slider 2 401 and the bottom plate 23 slide downward, and the compression spring 22 is squeezed when the bottom plate 23 slides, and the slider 2401 disengages from the slot at the bottom of the guide rail 1202. Then the cover plate 28 is rotated to drive the installation cylinder 26, the connecting cylinder 25, the rotating cylinder 24, the slider 2401 and the bottom plate 23 to rotate. The slider 2401 rotates to the lower end of the guide groove at the bottom of the guide rail 1202, and the cover plate 28 is released. The rebound force of the compression spring 22 drives the cover plate 28, the installation cylinder 26, the connecting cylinder 25, the rotating cylinder 24, the slider 2401 and the bottom plate 23 to slide upward, and the slider 2401 enters the guide groove at the bottom of the guide rail 1202. At this time, the through hole of the connecting cylinder 25 and the fixing box 12 is closed, and the cover plate 28 is unscrewed, and the desiccant bag 27 inside the installation cylinder 26 is taken out and replaced. After replacement, tighten the cover plate 28 again.Pressing the cover plate 28 causes the installation cylinder 26, connecting cylinder 25, rotating cylinder 24, slider 2401, and bottom plate 23 to slide downward. As the bottom plate 23 slides, the compression spring 22 is squeezed, causing the slider 2401 to disengage from the guide groove at the bottom of the guide rail 1202. The cover plate 28 is then rotated in the opposite direction, causing the slider 2401 to rotate to the lower end of the slot on the guide rail 1202. The cover plate 28 is released, and the rebound force of the compression spring 22 causes the cover plate 28, installation cylinder 26, connecting cylinder 25, rotating cylinder 24, slider 2401, and bottom plate 23 to slide upward. The slider 2401 enters the slot at the bottom of the guide rail 1202 and is fixed. At this point, the installation cylinder 26 is connected to the through hole of the fixing box 12, thereby completing the replacement of the desiccant pack 27.
