Description

Technical Field

[0001] The utility model relates to the technical field of toner cartridges, and more specifically, to a recyclable toner cartridge. Background Art

[0002] The toner drum is a cylinder coated with organic material on its surface. It is pre-charged. When light is irradiated, the irradiated parts will react with resistance, and the data signal sent controls the emission of the laser. The light scanning on the surface of the toner drum keeps changing, so that some places are irradiated, the resistance becomes smaller, and the charge disappears, while some places are not irradiated by light and still retain the charge. Finally, a latent image composed of electric charges is formed on the surface of the toner drum, and the toner powder in the toner drum is a kind of charged fine resin particles. The charge of the toner powder is opposite to the charge polarity on the surface of the toner drum. When the charged toner drum surface passes through the inking roller, the charged parts adsorb the toner particles, thus turning the latent image into a real image.

[0003] After the toner in the existing toner cartridge is used, the waste toner remaining on the photosensitive drum will be stored centrally. The waste toner needs to be poured out and processed before being recycled. The release of waste toner during this process can easily lead to environmental pollution. Utility Model Content

Electromagnets are installed at both ends of the top of the mounting plate 8. A metal sheet that is magnetically attracted to the electromagnet is provided at the bottom of the baffle 10. When the electromagnet is not turned on, the baffles 10 at both ends do not contact the photosensitive drum 2 and the developing roller 4, and do not affect the rotation of the photosensitive drum 2 and the developing roller 4. When the electromagnet is turned on, the metal sheet is driven by suction to rotate the baffle 10 to fit the photosensitive drum 2 and the developing roller 4, thereby realizing the closure of the powder bin and the waste powder bin.

[0022] The recovery mechanism includes a fixed box 11, an air suction pump 12 and a connecting pipe 13. The fixed box 11 is installed on the other end of one side of the toner cartridge frame 1. The air suction pump 12 is installed on one side of the fixed box 11. The output end of the air suction pump 12 is connected to the connecting pipe 13. The connecting pipe 13 is connected to one end of one side of the toner cartridge frame 1. The connecting pipe 13 is connected to the powder bin. A filter plate 14 is provided at the upper end of the interior of the fixed box 11. A socket adapted to the size of the filter plate 14 is provided on the top of the fixed box 11. The top of the filter plate 14 extends out of the socket part. Through holes are provided on both sides of the fixed box 11. One side of 1 is provided with a through hole that is connected to the through hole, and the through hole is connected to the waste powder bin. The input end of the suction pump 12 is connected to the through hole of the fixed box 11. The interior of the fixed box 11 is provided with a clamping assembly, which includes a fixing plate 15. The fixing plate 15 is installed at the bottom of the interior of the fixed box 11. One end of the fixing plate 15 is elastically connected to a push rod 17 through a buffer spring 16. The bottom end of the push rod 17 is slidably connected to the bottom of the interior of the fixed box 11. One end of the fixed box 11 is provided with a pressing hole that is slidably connected to the push rod 17. One end of the push rod 17 extends out of the fixed box 11 part for easy use. The user presses the push rod 17 outside the fixed box 11, and the top of the push rod 17 is engaged with a spur gear 18. The inner side of the spur gear 18 is interspersed with a rotating rod 1. One side of the rotating rod 1 is rotatably mounted on the inner wall of the fixed box 11. The other side of the rotating rod 1 is installed with a bevel gear 19. The upper end of the bevel gear 19 is engaged with a bevel gear 20. The extension lines of the center points of the bevel gear 19 and the bevel gear 20 are perpendicular to each other. The inner side of the bevel gear 20 is interspersed with a rotating rod 2. The bottom of the rotating rod 2 is rotatably mounted on the bottom of the fixed box 11. The top of the rotating rod 2 is installed with a spur gear 21. The outer side of the spur gear 21 is symmetrically provided with two tooth plates 22, which are slidably connected to the inner wall of the fixed box 11. The inner sides of the two tooth plates 22 are meshed with the outer side of the spur gear 21. The two tooth plates 22 are installed with clamping blocks 23 at one end away from each other. The rotation of the spur gear 21 realizes the movement of the two tooth plates 22 and the clamping blocks 23 towards or away from each other. The inner side of the clamping blocks 23 is provided with anti-slip strips, which are squeezed and contacted with the two ends of the filter plate 14. The friction resistance with the filter plate 14 is increased by the anti-slip strips to achieve the clamping and fixation of the filter plate 14.

[0023] Working principle: When recycling waste powder in the waste powder bin, start the electromagnet on the top of the mounting plate 8, and the metal sheet at the bottom of the baffle 10 moves under suction, driving the baffle 10 to rotate, and the baffle 10 squeezes the limit spring 9. When the baffle 10 rotates, it fits the photosensitive drum 2 and the developing roller 4 respectively. At this time, the powder bin and the waste powder bin are closed, and then start the suction pump 12 to drive the waste powder in the waste powder bin into the fixed box 11. After being filtered by the filter plate 14, it enters the powder bin for recycling through the connecting pipe 13. When in use, turn off the electromagnet, and the baffle 10 rotates in the opposite direction due to the thrust of the limit spring 9 to realize the opening of the bottom opening of the drum frame 1. When replacing the filter plate 14, press the push rod 17, and the push rod 17 squeezes the buffer spring 16. When the push rod 17 slides, it drives the spur gear 18 to rotate, and the spur gear 18 drives the rotating rod 1 and the bevel gear 19 to rotate. The bevel gear 19 drives the bevel gear 20 to rotate, and the bevel gear 20 drives the rotating rod 2 and the spur gear 21 to rotate. The spur gear 21 drives the tooth plate 22 and the clamping block 23 to slide. The two clamping blocks 23 slide toward one end away from each other, and the anti-slip strips on the clamping blocks 23 are out of contact with the filter plate 14. At this time, the filter plate 14 is pulled out and replaced, and then the push rod 17 is released. The thrust of the buffer spring 16 drives the push rod 17 to slide in the opposite direction, and the two clamping blocks 23 slide in the opposite direction. The anti-slip strips on the clamping blocks 23 clamp and fix the filter plate 14, thereby completing the replacement of the filter plate 14.
