Description

Technical Field

[0001] The utility model relates to the technical field of printing material equipment, in particular to a toner cartridge with a waste powder recycling function. Background Art

[0002] In the current field of printing equipment, toner cartridges with waste powder recovery functions have emerged. The specific recovery process is as follows: after the toner in the powder bin is adsorbed onto the photosensitive drum, a cleaning scraper scrapes off the toner that has not been adsorbed onto the paper on the photosensitive drum, causing it to fall into the recovery bin. The waste powder that has fallen into the recovery bin then passes through the connecting structure between the recovery bin and the powder bin and re-enters the powder bin for recycling. However, there is a significant problem with existing waste powder recycling devices: during the waste powder recovery process, the waste powder is simply naturally transferred from the recovery bin to the powder bin by the connecting structure between the recovery bin and the powder bin, and the toner cartridge does not have a structure that can actively promote the transfer of waste powder, resulting in low waste powder transfer efficiency, which in turn leads to low waste powder utilization by the toner cartridge, making the toner cartridge less competitive in the market. Therefore, there is an urgent need for a toner cartridge with a waste powder recovery auxiliary structure that, while having a waste powder recovery function, further promotes the transfer of waste powder and improves the waste powder utilization rate of the toner cartridge.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to the attached Figure 1 To the attached Figure 5 , this embodiment provides a toner cartridge with a waste powder recycling function, including a powder bin 1, a recovery bin 2 and a recovery mechanism 3 arranged between the powder bin 1 and the recovery bin 2, a recovery port 21 is provided between the powder bin 1 and the recovery bin 2, the recovery mechanism 3 includes a linkage rod 31 and a recovery part 32, the linkage rod 31 is rotatably arranged, and the recovery part 32 extends into the recovery port 21, and an eccentric section 311 is provided on the linkage rod 31 and is eccentrically arranged with respect to the rotation axis. The eccentric section 311 is connected to the recovery part 32, so that the rotation of the linkage rod 31 drives the recovery part 32 to move back and forth at the recovery port 21, so as to continuously push the waste powder in the recovery bin 2 into the powder bin 1 through the recovery port 21. The toner cartridge with waste powder recycling function of this embodiment is provided with a recycling mechanism 3 between the powder bin 1 and the recycling bin 2. The recycling mechanism 3 includes a linkage rod 31 and a recycling part 32. The rotatable linkage rod 31 adopts an eccentric section 311, and the eccentric section 311 is connected to the recycling part 32, so that when the linkage rod 31 rotates, the continuous eccentric rotation of the eccentric section 311 can drive the recycling part 32 to perform a circular reciprocating movement, thereby continuously pushing the waste powder in the recycling bin 2 back into the powder bin 1 through the recycling port 21, thereby realizing the efficient transfer of the waste powder in the recycling bin 2 by the toner cartridge for recycling, and improving the competitiveness of the toner cartridge products in the market.

[0026] The recycling member 32 includes a push plate portion 321 and a catch portion 322. The push plate portion 321 includes a low push plate 3211, a high push plate 3212, and an inclined plate 3213 connecting the edges of the low push plate 3211 and the high push plate 3212. The catch portion 322 is clamped to the outside of the eccentric segment 311 around the axial direction of the eccentric segment 311. When the recycling member 32 moves in a direction approaching the powder bin 1, the low push plate 3211 abuts the bottom surface of the inner cavity of the recycling bin 2, and the lower side of the inclined plate 3213 abuts and pushes the waste powder in the recycling bin 2. When the linkage rod 31 rotates and drives the recycling member 32 to move back and forth, the low push plate 3211 will first rise, then extend into the recycling bin 2, then press down to abut the bottom surface of the inner cavity of the recycling bin 2, and then move in a direction away from the recycling bin 2, causing the lower side of the inclined plate 3213 to push out the waste powder, and then rise again to start the next cycle.

[0027] Furthermore, a plurality of hollow portions 3214 are formed on the lower push plate 3211 and the upper push plate 3212. In this embodiment of the toner cartridge with the waste powder recycling function, a plurality of hollow portions 3214 are formed on the push plate portion 321 where the recycling member 32 extends into the recycling bin 2. This allows the portion of the push plate portion 321 extending into the recycling bin 2 to stir the waste powder in the recycling bin 2 when the recycling member 32 moves back and forth, thereby continuously breaking up the waste powder and preventing the waste powder from agglomerating in the recycling bin 2, thereby ensuring the normal recycling effect of the recycling mechanism 3.

[0028] The catch portion 322 includes a connecting arm 3221 and a semicircular catch 3222. The connecting arm 3221 is connected to the edge of the upper push plate 3212 away from the lower push plate 3211. The semicircular catches 3222 are arranged in pairs on the side of the connecting arm 3221 away from the push plate portion 321. The paired semicircular catches 3222 simultaneously clamp onto both sides of the eccentric section 311. The paired semicircular catches 3222 facilitate the connection between the linkage rod 31 and the recovery member 32 during installation, eliminating the need for a threaded connection.

[0029] The eccentric segments 311 are arranged in multiple sections on the linkage rod 31, and the catch portions 322 are arranged in multiple groups on the edge of the high-position push plate 3212. The recovery ports 21 are multiple settings opened in the recovery bin 2, and the corresponding eccentric segments 311 and the catch portions 322 are directly opposite to the corresponding recovery ports 21. This setting enables the recovery mechanism 3 to be flexibly set for toner cartridges of different specifications to ensure the recovery efficiency of the toner cartridges.

[0030] There are spacer connecting ribs 22 between adjacent recovery ports 21 on the recovery bin 2, and a plurality of clearance ports 3215 are arranged on the edge of the high-position push plate 3212 away from the low-position push plate 3211. When the recovery part 32 moves in the direction close to the powder bin 1, the spacer connecting ribs 22 extend into the corresponding clearance ports 3215. This cooperation has a certain guiding effect on the movement of the push plate part 321, making the movement of the push plate part 321 more stable.

[0031] The push plate portion 321 and the plurality of catch portions 322 are integrally formed, which facilitates the production of the recycling unit 32 .

[0032] One end of the linkage rod 31 is provided with a linkage plug connector 312, which is used to coaxially connect and rotate a linkage gear set on the toner cartridge. The linkage gear can be engaged with the driving gear set of the toner cartridge, so that the recovery mechanism 3 follows the driving gear set of the toner cartridge.

[0033] A limit plate 313 is provided at one end of the linkage rod 31 away from the linkage plug connector 312. The limit plate 313 is used to limit the movement of the catch portion 322 along the length direction of the linkage rod 31, thereby preventing the catch portion 322 from escaping from the linkage rod 31 along the length direction of the linkage rod 31.

[0034] The main shaft, the multiple eccentric sections 311 , the linkage plug connector 312 and the limiting plate 313 on the linkage rod 31 are integrally formed, which facilitates the production of the linkage rod 31 .

[0035] The recovery mechanism 3 also includes a corresponding safety seal 33 and a seal insert 34. The safety seal 33 is detachably disposed between the powder silo 1 and the recovery bin 2. The seal insert 34 is provided on the side of the powder silo 1. The safety seal 33 can be removed through the seal insert 34 to release the seal on the recovery port 21. The safety seal 33 provided between the powder silo 1 and the recovery bin 2 effectively prevents the carbon powder in the powder silo 1 from flowing back into the recovery bin 2 through the recovery port 21 during transportation. The seal insert 34 also allows the safety seal 33 to be removed from the recovery port 21 by simply withdrawing it through the seal insert 34, which is convenient and quick.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
