Description

Powder box and refitting method thereof

Technical Field

The invention relates to the technical field of electrophotographic imaging, in particular to a large-capacity powder box and a refitting method of the powder box.

Background

The existing powder box wastes a lot of space due to the fact that a larger gap is formed between the developing box and the drum box and the size of the handle is large, and meanwhile due to the limitation of the whole structure of the powder box and the space of a printer, the space of a powder cabin of the powder box is smaller, the capacity of accommodated carbon powder is low, and the yield of printing pages is lower. When the end user uses up the carbon powder in the powder box, the photosensitive drum of the powder box can also continue to use, other parts in the powder box can also continue to use, if the powder box is discarded, unnecessary waste of parts such as the photosensitive drum and the like can be caused, and the user also needs to buy a new powder box again, so that the use cost of the end user is higher.

Disclosure of Invention

The first purpose of the invention is to provide a method for modifying a powder box for improving the capacity of carbon powder.

The second purpose of the invention is to provide a method for modifying the powder box, which realizes the capacity expansion and regeneration of the powder box through modifying the powder box.

In order to achieve the first purpose, the invention provides a powder box, which comprises a developing box and a drum box, wherein the developing box comprises a powder bin and a stirring frame, the stirring frame is rotatably installed in the powder bin, the drum box is arranged above the developing box, the drum box comprises an upper cover, a lower shell, a cleaning scraper and a photosensitive drum, the upper cover is provided with a handle, the upper cover and the lower shell are enclosed to form a waste powder storage bin, the cleaning scraper and the upper cover are enclosed to form a waste powder collecting bin, the waste powder storage bin and the waste powder collecting bin are arranged along the width direction of the powder box, two ends of the waste powder collecting bin in the width direction are respectively provided with a first opening and a second opening, the photosensitive drum is positioned at the first opening, and the waste powder collecting bin is communicated with the waste powder storage bin through the second opening. The refitting method comprises the following steps: a powder supplementing opening is formed at the top of the powder bin; cutting the upper cover and removing the extension part including the handle on the upper cover, wherein the new upper cover forms a carbon powder supplement box mounting position at the cutting position; and a carbon powder supplementing box is additionally arranged, a supply port at the bottom of the carbon powder supplementing box is in sealed butt joint with the powder supplementing port, and the carbon powder supplementing box is arranged at a carbon powder supplementing box mounting position.

According to the scheme, the capacity of the powder bin is expanded by adding the carbon powder supplementing box above the developing box, so that the printing page yield of the product is enlarged, the use cost of the product is effectively reduced for a terminal user, and the use convenience of the user is improved.
