Description

Technical Field

[0001] The utility model relates to the technical field of imaging printing, in particular to the technical field of processing boxes required for laser printing. Background Art

[0002] The processing box is a commonly used consumable for imaging printing equipment, which stores toner. When the electronic photographic imaging device is working, an electrostatic latent image is formed on the surface of the photosensitive drum installed in the processing box or the imaging printing device. The toner develops the electrostatic latent image, and then the image is transferred to the imaging medium by the transfer mechanism.

[0003] When the toner in the processing cartridge is consumed, the user needs to replace it with a new one. Therefore, for the user, the more toner in the processing cartridge, the longer the service life of the processing cartridge, and correspondingly, the lower the user's cost of use. However, the capacity of existing processing cartridges is often small. When the toner is consumed, the core components of the processing cartridge still have use value. Therefore, it is necessary to improve the existing processing cartridge and expand the toner capacity of the processing cartridge without affecting the smooth combination and disengagement of the processing cartridge with the electronic photographic imaging device, thereby ultimately reducing the user's cost of use and avoiding wasting the use value of the core components of the processing cartridge.

This design enables the waste toner bin assembly 112 to store more waste toner without increasing the overall height of the processing box 100 (i.e., the size in the z-direction).

[0049] Reference Figure 2 Specifically, viewed along the axial direction of the photosensitive drum 111 (i.e., the y-axis direction), the size of the powder bin assembly along the x-axis direction is L1, the size of the main powder bin along the z-axis direction is L2, and the size L1 of the powder bin assembly along the x-axis direction is greater than the size L2 of the main powder bin along the z-axis direction, i.e., L1>L2. This design enables the powder bin to store more toner and to make the most of the space in the x-axis direction. Specifically, the size L1 of the powder bin assembly along the x-axis direction is the size of the accommodating inner cavity of the powder bin assembly along the x-axis direction, and the size L2 of the powder bin assembly along the z-axis direction is the size of the accommodating inner cavity of the powder bin assembly along the z-axis direction.

This design further utilizes the space of the processing box 100 in the z-axis direction, further increasing the storage capacity of waste powder. Preferably, the size of the second expanded waste powder bin 112b2 can be adjusted according to actual needs to ensure that it will not interfere with other components during installation and use.

[0053] Preferably, the main powder bin 122a, the first capacity expansion powder bin 122b1 and the second capacity expansion powder bin 122b2 are connected to ensure that carbon powder will not be left in the capacity expansion powder bin 122b when the processing box 100 is used.

[0054] Preferably, a stirring member (not shown in the figure) is provided in the powder bin assembly 122. The function of the stirring member is to prevent the toner from agglomerating for a long time by stirring the toner in the powder bin assembly 122. The stirring of the stirring member can deliver the toner to the developing roller 121 more quickly, shortening the process from stirring the toner to forming an image. This helps to improve the overall working efficiency of the printer and reduce the waiting time of users.

The first gear 131a receives the driving force from the imaging device and transmits the driving force to the second transmission member 132, so that the photosensitive drum 111 and the developing roller 112 rotate.

[0058] In this embodiment, a laser passing gap 140 is provided between the developing unit 120 and the photosensitive unit 110. The imaging device emits laser light, and the laser light passes through the laser passing gap 140 and then hits the photosensitive drum 111. A layer of photosensitive material (not shown) is coated on the surface of the photosensitive drum 111. When the laser light hits the photosensitive drum 111, the photosensitive drum receives the light signal during the imaging process and converts it into an electrostatic latent image.

The photosensitive drum protective shell 150 is used to protect the photosensitive drum 111 to avoid damage to the photosensitive drum 111 during transportation or other situations, which would result in poor imaging quality.

[0060] The present invention further provides an imaging device (not shown in the figure), which includes the process box 100 of the above-mentioned embodiment, a transfer roller (not shown in the figure), a driving component and a housing.
