Description

Technical Field

[0001] This utility model relates to the field of printer toner cartridge feeding technology, specifically a printer toner cartridge feeding mechanism. Background Technology

[0002] The printer toner cartridge is a key component in a laser printer, responsible for storing and delivering toner to the photosensitive drum for printing.

[0003] Existing printer toner cartridges require frequent refilling, necessitating the use of a feeding mechanism. For example, Chinese Patent Publication No. CN221273606U discloses a printer toner cartridge feeding mechanism. This mechanism involves a vertical rod that is movable on the outer periphery of a central rod between limiting plates. A pull plate is fixedly connected to both ends of the toner cartridge and the vertical rod, with an elastic element fixed between the limiting plates and the vertical rod. The central rod is positioned in the middle of this elastic element. Pulling the pull plate causes a rubber brush head to clean the toner from the gaps in the toner cartridge. The cleaned toner can then be poured out through the discharge pipe at the bottom of the toner cartridge, improving printing quality. The toner is stirred evenly in the material tank by a stirring shaft before being introduced into the feeding hopper. A quantitative valve on the front of the filling head controls the amount of toner, preventing insufficient toner in the cartridge (reducing usability) or excessive overflow, thus improving the device's practicality.

[0004] While existing technologies enable the cleaning of toner cartridges and the quantitative addition of toner, they involve aligning the filling port on the top of the toner cartridge with the filling head for dispensing. However, due to the characteristics of toner, powder may fly during the dispensing process, causing toner to escape and posing a safety hazard. Furthermore, the alignment of the toner cartridge's filling port and the filling head is done manually, which can lead to incomplete alignment and affect toner addition. Therefore, those skilled in the art have proposed a printer toner cartridge dispensing mechanism to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a printer toner cartridge feeding mechanism to solve the problems mentioned in the background art.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] Please see Figures 1-3 A printer toner cartridge feeding mechanism includes a base 1, a support platform 2 mounted on the base 1, a storage bin 3 mounted on the support platform 2, brackets 4 and a feeding bin 13 mounted on both sides of the support platform 2, a conversion block 5 mounted on the brackets 4, a rotating shaft 6 rotatably mounted inside the conversion block 5, a conversion disc 7 mounted on the rotating shaft 6 and fitting against the inner wall of the conversion block 5, a guide channel 9 provided on the conversion disc 7, a suction pipe 10 connected to the conversion block 5, a delivery pump 11 mounted on the suction pipe 10, and a delivery pipe 12 between the conversion block 5 and the feeding bin 13, and further includes:

[0022] A feeding head 14 is set at the bottom of the feeding box 13. The bottom of the feeding head 14 is a funnel cavity 15. A metering valve 16 is set in the funnel cavity 15. A sealing retaining ring 17 is also installed on the feeding head 14.

[0023] An alignment connection mechanism is provided to achieve alignment between the feeding head 14 and the toner cartridge feeding port.

[0024] The cleaning mechanism, which is connected to the conversion block 5, is used to clean the residual carbon powder in the feeding box 13.

[0025] The alignment mechanism ensures proper alignment between the feeding head 14 and the toner cartridge filling port, and also seals the filling port, preventing toner from scattering into the environment during toner addition and making the process safer. The metering valve 16 then adds the toner in a measured quantity. After adding the toner, a cleaning mechanism collects and cleans any residual toner in the feeding box 13, feeding head 14, and conveying pipe 12, enabling the recycling of the residual toner.

[0026] In one embodiment, the flow channel 9 is V-shaped.

[0027] In this embodiment, since the guide channel 9 is V-shaped, in the initial state, the two ends of the guide channel 9 are connected to the suction pipe 10 and the conveying pipe 12 respectively. At this time, under the operation of the conveying pump 11, the suction pipe 10 will suck up the toner inside the storage box 3 and convey the toner into the guide channel 9, and then enter the feeding box 13 from the conveying pipe 12. When the conversion disk 7 rotates 90 degrees, the two ends of the guide channel 9 are connected to the conveying pipe 12 and the cleaning mechanism respectively. At this time, the cleaning mechanism can clean the residual toner in the feeding box 13, the feeding head 14, etc.

[0028] In one embodiment, the alignment connection mechanism includes hydraulic rods 22 installed on both sides of the base 1, and a limiting alignment frame 23 is installed on the hydraulic rods 22. The limiting alignment frame 23 has the same size and specifications as the toner cartridge.

[0029] In this embodiment, when adding toner to the toner cartridge, the cleaned toner cartridge is placed inside the limiting alignment frame 23. The limiting alignment frame 23 ensures that the feeding port on the toner cartridge automatically aligns with the feeding port after the toner cartridge is placed in place. Then, the external controller activates the hydraulic rod 22, which drives the limiting alignment frame 23 to rise, causing the toner cartridge to rise synchronously until the funnel cavity 15 of the feeding port enters the toner cartridge from the feeding port. The sealing ring 17 of the feeding head 14 then adheres to the top surface of the toner cartridge. This prevents toner from scattering into the external environment during the toner cartridge addition process, making toner addition safer.

[0030] In one embodiment, the cleaning mechanism includes brackets 4 installed on both sides of the base 1. A powder collection and filter box 20 is installed on the brackets 4. The powder collection and filter box 20 is connected to the conversion block 5 through a guide pipe 19. The powder collection and filter box 20 is connected to a fan 21. In order to facilitate the generation of airflow, a ventilation filter structure can be provided on the top of the feeding box 13 to facilitate air intake and prevent carbon powder from overflowing.

[0031] The conversion block 5 is equipped with a motor 8, and the output shaft of the motor 8 is connected to the rotating shaft 6.

[0032] In this embodiment, after the toner cartridge is filled, the external controller starts the motor 8, which drives the rotating shaft 6 to rotate 90 degrees, causing the conversion disk 7 to rotate 90 degrees. This allows the guide channel 9 in the conversion disk 7 to connect with the conveying pipe 12 and the connecting pipe 19. Then, the fan 21 is started, causing the connecting pipe 19 to generate suction force, thereby sucking up the residual toner in the feeding head 14, feeding box 13, etc., and collecting the toner in the powder collection filter box 20. This achieves the recycling of residual toner and also cleans the residual toner, preventing the toner from being in the feeding box 13 and feeding head 14 for a long time, which could cause blockage of the contact block.

[0033] This invention utilizes an alignment connection mechanism to ensure proper alignment between the feeding head 14 and the toner cartridge filling port, and to seal the filling port, thus preventing toner from scattering into the environment during toner addition and making toner addition safer. The toner is then quantitatively added via the metering valve 16. After toner addition, a cleaning mechanism collects and cleans residual toner from the feeding box 13, feeding head 14, and conveying pipe 12, enabling the recycling of residual toner.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
