Description

Technical Field

[0001] The present invention relates to the technical field of developer supply containers, and in particular to a developer supply container and a developer supply method. Background Art

[0002] A developer supply container and a storage container that store developer inside a known image forming device. The image forming device includes a carrier, a developing device, a developer supply container and a storage container. If developer is supplied from the developing device to the image carrier, the electrostatic latent image formed on the image carrier is visualized as a developer image. The developer supply container includes a developer discharge port to supply developer to a supply port of the developing device. At the same time, the developer supply container also has the function of collecting waste developer. After the developer passes through the image forming device, waste developer is discharged and enters the waste developer bin of the developer supply container through another waste developer inlet of the developer supply container.

[0003] However, in the process of operation of the existing developer supply container, since the developer discharge port is located in the middle, in order to make the developer flow to the middle of the developer supply container, a developer stirring rod is provided in the developer compartment of the supply container. The rotating shaft usually adopts an arched structure to realize powder feeding, but its structural design has defects and is difficult to process. In addition, in the process of stirring the developer, it is easy to cause the overall torque to be too large, resulting in unsmooth developer discharge. At the same time, in the original developer supply container, the two ends of the developer stirring rod are positioned with a shaft, so that there will be uneven force during the stirring process.

[0046] The powder return mechanism 4 is used to stir the waste developer powder generated by the image forming device received by the waste powder bin 2;

[0047] The powder loading mechanism 3 includes a powder outlet shaft 31 rotatably connected to the inside of the main powder bin 1, and the powder outlet shaft 31 extends to the external limit of the main powder bin 1 and is connected with a powder bin gear 34. After the main powder bin 1 and the image forming device are assembled, the powder bin gear 34 is meshed with the gear of the image forming device, and the image forming device drives the powder bin gear 34 device through the gear.

[0048] In an optional embodiment, a waste powder bin powder inlet 13 is provided on the outside of the waste powder bin 2 , and a waste powder bin cover 14 is inserted into the inside of the waste powder bin powder inlet 13 .

[0049] The main powder bin 1 is mounted on the image forming device, and the shifting block of the sliding cover 5 is horizontally offset from the powder bin buckle 6. At this time, the sliding cover 5 is manually pushed to the right, so that the powder bin outlet 7 of the main powder bin 1 coincides with the powder outlet 51 of the sliding cover 5, so that the developer can be supplied to the image forming device;

[0050] After the developer supply container is loaded onto the machine, its powder bin gear 34 meshes with the gear inside the image forming device. When the image forming device is working, it drives the powder bin gear 34 to rotate, and the powder outlet shaft 31 also rotates with the powder bin gear 34 to deliver the developer to supply toner to the image forming device.

[0051] refer to Figure 4 and Figure 5 In an optional embodiment: the outside of the main powder bin 1 is slidably connected with a sliding cover 5, the outside of the sliding cover 5 is provided with anti-slip grooves, the sliding cover 5 is provided with a through powder outlet 51, the middle of the main powder bin 1 is provided with a powder bin outlet 7 for connecting to an image forming device, the sliding cover 5 slides on the outside of the main powder bin 1 to control the misalignment and overlap of the powder outlet 51, the outside of the main powder bin 1 is provided with an integrally formed powder bin buckle 6, the inside of the sliding cover 5 is provided with an integrally formed shift block, the shift block is shifted horizontally, and the shift block is adapted to the powder bin buckle 6.

[0052] It should be noted that the sliding cover 5 is pushed sideways by the push block, and then the sliding cover 5 is pushed forward, so that the powder outlet 51 of the sliding cover 5 overlaps with the powder bin outlet 7, thereby realizing the powder outlet opening.

[0053] It should be noted that the locking arrangement of the sliding cover 5 and the main powder bin 1 is a universal structure.

[0054] Among them, the sliding cover 5 is controlled by pushing the block open from the side. Compared with the traditional method of pushing it open downward and then pushing it forward, the design of the sinking space can be eliminated, which is convenient for maintaining the sealing of the sliding cover 5 and the main powder bin 1, and at the same time effectively reduces the processing difficulty of the overall positioning and matching. The overall structure is simpler, and can effectively maintain the matching of the sliding cover 5 and the main powder bin 1, while reducing the processing cost of the device.

[0058] The first stirring blades 32 on both sides rotate to realize multi-point pushing. Under the push of the multiple first stirring blades 32 on both sides, the powder gradually flows to the middle, and then is pushed by the second stirring blades 33 to pass through the powder bin outlet 7.

[0059] Since two rows of first stirring blades 32 and a second stirring blade 33 horizontally arranged in the middle are arranged on the outside of the powder outlet shaft 31, the feeding effect of the developer is effectively guaranteed. In addition, the multi-point design is simpler to process than the existing arch setting, and the manufacturing difficulty and cost are effectively reduced. At the same time, since each first stirring blade 32 is in an independent state, the problem of excessive overall torque is effectively avoided, and the overall deformation caused by uneven force on the blades is effectively avoided, thereby affecting the overall feeding effect. At the same time, one end of the powder outlet shaft 31 is sleeved on the outside of the side cover inner ring 91 of the powder bin side cover 9 through the positioning ring 35, so as to avoid that both ends of the powder outlet shaft 31 are matched with the shaft through the positioning hole, thereby further improving the force uniformity of the powder outlet shaft 31 during rotation.

[0060] By arranging a powder bin side cover 9 on the side of the main powder bin 1 and adding a plug 10 on the outside of the powder bin side cover 9, compared with the traditional method of directly fixing and sealing by the side cover, the side cover cannot be reused after being fixed. By adding the plug 10 on the powder bin side cover 9, the secondary utilization effect of the main powder bin 1 can be increased, thereby improving the practicality of the overall device.

[0064] It should be noted that the first gear set 12 can select gear specifications and gear quantity according to actual processing or production requirements. The first gear set 12 is used for transmission connection between the powder bin gear 34 and the waste powder bin gear 43, and is used to maintain the synchronous rotation of the powder bin gear 34 and the waste powder bin gear 43.
