Description

Technical Field

[0001] The utility model relates to the technical field of toner cartridge adding powder, in particular to a toner adding powder mechanism for a printer toner cartridge. Background Art

[0002] The toner drum, also known as the photosensitive drum, is a key hardware in the printer. Inside the printer, the toner drum is responsible for converting electronic signals into actual images. When the laser beam shines on the surface of the toner drum, the light-exposed area will undergo a change in resistance, forming an electrostatic latent image. Subsequently, high-voltage static electricity is used to adsorb the toner onto these latent images to complete the printing of the image.

[0003] The toner cartridge also has the function of storing toner. Toner is one of the important consumables in the printer and is used to transfer images or text to paper during the printing process. The toner in the toner cartridge is generally added by directly adding the toner by inserting the toner bottle. However, there is generally a channel in the toner cartridge, and this channel is used to insert the bottle mouth of the toner bottle. When the toner is completely poured out of the toner bottle, it is easy for toner to remain in this powder inlet channel. In addition, there is a phenomenon that toner flows back into this channel when the toner cartridge is working. However, the toner in this channel cannot be used. For this reason, we propose a printer toner cartridge toner adding mechanism. Utility Model Content

At the same time, the blocking block 202 prevents the internal toner from flowing back into the fixed tube 201, so that the toner can be fully utilized by the toner cartridge.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] The embodiment of the utility model discloses a toner adding mechanism for a printer toner cartridge.

[0028] According to the attached Figure 1-3, including a shell 101, a powder feeding assembly, a dredging mechanism and a sealing mechanism. A powder adding port 102 is provided on one side of the shell 101. The powder adding port 102 is a channel for adding toner into the shell 101. The powder feeding assembly is arranged inside the powder adding port 102. The powder feeding assembly includes a fixed tube 201, which is fixedly inserted and connected to the inner wall of the shell 101. The fixed tube 201 is used for inserting a toner bottle to add powder into the shell 101. A blocking block 202 is inserted into the interior of the fixed tube 201. A frustum 203 is provided on the outer wall of the blocking block 202. The frustum 203 is used to block the fixed tube 201 and separate the interior of the shell 101 from the interior of the fixed tube 201. A connecting mechanism is provided between the blocking block 202 and the fixed tube 201. The dredging mechanism is arranged inside the shell 101. The dredging mechanism is used to dredge the toner bottle for adding powder. The sealing mechanism The mechanism is set at one end of the fixed tube 201 away from the blocking block 202. The sealing mechanism is used to separate the interior of the fixed tube 201 from the outside. When the toner bottle is inserted into the fixed tube 201, the blocking block 202 will move and separate from the fixed tube 201, so that the fixed tube 201 no longer presses against the outer wall of the frustum 203, that is, there is a gap between the fixed tube 201 and the frustum 203, and the oblique surface of the frustum 203 is set to facilitate the toner to flow into the interior of the shell 101. When the toner in the toner bottle is added, the toner bottle body can be slightly pinched to generate a certain air pressure at the bottle mouth of the toner bottle, so that the toner in the fixed tube 201 and the toner attached to the surface of the frustum 203 can be blown into the interior of the shell 101, avoiding the toner from staying at the powder adding position. At the same time, the blocking block 202 prevents the internal toner from flowing back into the fixed tube 201, so that the toner cartridge can fully utilize the toner.

[0029] Among them, the connecting mechanism includes a connecting rod 302, one end of each of the multiple connecting rods 302 is fixedly connected to the outer wall of the conical surface 203, and a plurality of connecting holes 301 are opened at one end of the fixed tube 201 close to the inside of the shell 101. The outer walls of the multiple connecting rods 302 are movably connected with the inner walls of the multiple connecting holes 301 respectively, and an extrusion mechanism is provided inside the connecting hole 301. The connecting rod 302 is limited and guided through the connecting hole 301, so that the moving direction of the blocking block 202 is consistent with the moving direction of the connecting rod 302 in the connecting hole 301, so that when the blocking block 202 blocks the fixed tube 201, the blocking block 202 can be stably moved to the outer wall of the conical surface 203 completely against the fixed tube 201, thereby improving the stability of the blocking block 202 in use.

[0030] Among them, the extrusion mechanism includes a fixed ring 402, and a movable groove 401 is provided on the inner wall of the connecting hole 301. The outer wall of the fixed ring 402 is slidably connected to the inner wall of the movable groove 401. The outer wall of the connecting rod 302 is fixedly inserted and connected with the inner wall of the fixed ring 402. A spring 403 is provided between the fixed ring 402 and the inner wall of the movable groove 401. The spring 403 is sleeved on the outside of the connecting rod 302. Through the elastic action of the spring 403, the spring 403 is always squeezing the fixed ring 402, that is, under the connection of the connecting rod 302, the blocking block 202 always has a tendency to move toward the fixed tube 201, that is, when the blocking block 202 is not subjected to a large external force, the blocking block 202 can be stably stuck at the opening of the blocking block 202, thereby improving the stability of the use of the blocking block 202.

[0031] Among them, the unblocking mechanism includes an insertion rod 501, one end of the insertion rod 501 is fixedly connected to the outer wall of the blocking block 202, and a tip 502 is provided at the end of the insertion rod 501 away from the blocking block 202. The length of the insertion rod 501 is less than the length of the fixed tube 201, and a limiting mechanism is provided on the outer wall of the insertion rod 501. When adding powder, the bottle mouth of the toner bottle is inserted into the fixed tube 201, and the insertion rod 501 is inserted into the bottle mouth of the toner bottle. The toner that is blocked in the bottle mouth of the toner bottle can be poked through the tip 502, so that the toner can flow out of the toner bottle stably, ensuring the smoothness of toner addition.

[0032] Among them, the limiting mechanism includes a limiting push rod 601, which is symmetrically fixed to the outer wall of the insertion rod 501, and the limiting push rod 601 and the blocking block 202 are arranged at intervals. When the bottle mouth of the toner bottle is inserted into the fixed tube 201, the insertion rod 501 will be inserted into the bottle mouth of the toner bottle until the toner bottle abuts the limiting push rod 601. At this time, the toner bottle continues to be inserted, which can make the limiting push rod 601 move. The movement of the limiting push rod 601 drives the insertion rod 501 to move, and the movement of the insertion rod 501 can drive the blocking block 202 to move, so that the fixed tube 201 no longer abuts the outer wall of the frustum 203, that is, there is a gap between the fixed tube 201 and the frustum 203, and the inclined surface of the frustum 203 is set to facilitate the toner to flow into the interior of the shell 101.

[0033] Among them, the sealing mechanism includes a sealing cover 701, which is arranged on the outside of the shell 101, a clamping mechanism is provided between the sealing cover 701 and the fixed tube 201, and an anti-lost mechanism is provided between the sealing cover 701 and the shell 101, and the clamping mechanism includes a clamping block 702, which is fixedly connected to the outer wall of the sealing cover 701, and the clamping block 702 is clamped on the inner wall of the fixed tube 201, and the outer wall of the sealing cover 701 is fixedly connected with a shifting block 703. After the toner is added to the toner cartridge, the clamping block 702 is clamped into the fixed tube 201, so that the sealing cover 701 covers the opening of the fixed tube 201, thereby sealing the fixed tube 201 and ensuring the stable operation of the toner cartridge. The sealing cover 701 is easily pulled by the shifting block 703 so that the clamping block 702 is pulled out from the fixed tube 201, thereby improving the convenience of operating the sealing cover 701.

[0034] Among them, the anti-lost mechanism includes a connecting strip 704, one end of the connecting strip 704 is fixedly connected to the outer wall of the sealing cover 701, and a fixing hole 705 is opened on the outer wall of the shell 101. The other end of the connecting strip 704 is fixedly inserted and connected with the inner wall of the fixing hole 705. The connecting strip 704 is fixed to the inner wall of the fixing hole 705 by strong glue. That is, under the connection of the connecting strip 704, the sealing cover 701 is always connected to the shell 101 during the powder adding process, and the sealing cover 701 will not be lost, thereby improving the stability of the use of the sealing cover 701.
