Description

Technical Field

[0001] The utility model relates to the technical field of selenium drum isolation, in particular to a selenium drum isolation component. Background Art

[0002] Toner cartridges, also known as photosensitive drums, are typically composed of a base aluminum substrate coated with a photosensitive material. In laser printers, over 70% of the imaging components are concentrated in the toner cartridge, and print quality is largely determined by the toner cartridge. This not only determines print quality but also the cost of the printer.

[0003] The toner in the toner cartridge consists of fine resin particles with an electrical charge of opposite polarity to the charge on the drum surface. As the charged drum surface passes over the inking roller, the charged areas attract the toner particles, transforming the latent image into a live image. As the drum rotates, the printing system delivers paper, which carries a charge of the same polarity as the drum surface, but much stronger. The paper then passes over the toner-laden drum, where the toner on the drum surface is attracted to the paper, forming the image. At this point, the toner and paper are held together solely by the electrical attraction. Before the paper exits the printer, it is heated to a high temperature, melting the toner and solidifying on the paper surface as it cools. After attaching the toner to the paper, the drum surface continues rotating, passing through a cleaner that removes any remaining toner, allowing for the next print cycle.

[0004] When the toner cartridge is in use, the photosensitive drum needs to be in contact with the charging roller. After the existing toner cartridge is manufactured, the photosensitive drum and the charging roller are in contact. However, after the toner cartridge is manufactured, there are still links such as warehousing and transportation. The photosensitive drum and the charging roller are in contact for a long time, and indentations are produced on the photosensitive drum, which affects the printing quality. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] like Figures 1 to 4 The toner cartridge isolation assembly shown is characterized in that it includes: a photosensitive drum 1 and a charging roller 2, the photosensitive drum 1 and the charging roller 2 are flexibly fitted to each other, mounting assemblies 3 are provided on the left and right sides of the photosensitive drum 1, sleeve assemblies 4 are provided on the left and right sides of the charging roller 2, guide assemblies 5 are provided on the left and right sides of the charging roller 2, a connecting mechanism 6 that can connect the photosensitive drum 1 and the charging roller 2 is provided between the right side of the photosensitive drum 1 and the charging roller 2, and a moving mechanism 7 that can drive the charging roller 2 to move along the guide assembly 5 between the photosensitive drum 1 and the right side of the charging roller 2.

[0022] The toner cartridge isolation assembly of the above structure can, after the toner cartridge is assembled, be driven by the user through the moving mechanism 7 to move the charging roller 2 along the guide assembly 5, so that the photosensitive drum 1 and the charging roller 2 that are flexibly bonded to each other are separated, the photosensitive drum 1 is installed in the toner cartridge through the installation assembly 3, and the charging roller is installed in the toner cartridge through the sleeve assembly 2. The photosensitive drum 1 and the charging roller 2 are connected and bonded by the connecting mechanism 6. Compared with the existing technology, it can prevent the photosensitive drum and the charging roller from being in contact for a long time after the toner cartridge is manufactured, thereby preventing indentations and affecting the printing quality.

[0023] like Figure 2 and 3As shown, in some embodiments of the present invention, the mounting assembly 3 includes a mounting seat 31 movably sleeved on the left end shaft of the photosensitive drum 1, and a split seat 32 is symmetrically clamped on the shaft at the right end of the photosensitive drum 1. Mounting holes 33 are provided on the mounting seat 31 and each of the split seats 32, and one of the split seats 32 is plugged into another of the split seats 32. The user sleeves the mounting seat 31 on the left end of the photosensitive drum 1 and fixes it in the toner cartridge through the mounting holes 33 with screws. Then the user clamps the symmetrically arranged split seats 32 on the right end of the photosensitive drum 1, and one of the split seats 32 is plugged into another of the split seats 32, and then fixes the split seat 32 to the toner cartridge through the mounting holes 33 with screws.

[0024] like Figure 3 As shown, in some embodiments of the present invention, the sleeve assembly 4 includes a sleeve 41 that is movably sleeved on the left and right sides of the charging roller 2, and a plug-in shaft 42 is fixed at the end of each sleeve 41. During installation, the user movably sleeves each sleeve 41 on the left and right ends of the charging roller 2, and the sleeve 41 is movably plugged into the guide assembly 5 through the plug-in shaft 42.

[0025] like Figure 3 As shown, in some embodiments of the present invention, the guide assembly 5 includes a first half guide groove 51 and a second half guide groove 52 symmetrically arranged on one side of each of the plug-in shafts 42, and a slot 53 and an insertion strip 54 are enclosed on the first half guide groove 51 and the second half guide groove 52. Screw holes 55 are provided on each of the first half guide grooves 51 and the second half guide grooves 52. During installation, the user docks the first half guide grooves 51 and the second half guide grooves 52 with each other so that the slots 53 and the insertion strips 54 are plugged into each other. At this time, the first half guide groove 51 and the second half guide groove 52 are combined to form a guide groove, and the plug-in shaft 42 is guided and plugged into the guide groove. Finally, the first half guide groove 51 and the second half guide groove 52 are fixedly installed in the toner cartridge through the screw holes 55 and the screws.

[0026] like Figure 3 and 4 As shown, in some embodiments of the present invention, the connecting mechanism 6 includes a first connecting rod 61 movably hinged on one of the split seats 32, a second connecting rod 62 movably hinged on one of the shaft sleeves 41, and a connecting rod 63 movably hinged between the first connecting rod 61 and the second connecting rod 62.

[0027] An extension plate 611 is fixed to each of the first connecting rod 61 and the second connecting rod 62 , and a tension spring 612 is connected and fixed between the extension plates 611 .

[0028] When in use, the user rotates the moving mechanism 7 to cause the connecting rod 63 to move. When the connecting rod 63 moves, it drives the first connecting rod 61 and the second connecting rod 62 to swing, so that the first connecting rod 61 and the second connecting rod 62 extend relative to each other. At this time, the second connecting rod 62 drives the sleeve 41 to move along the guide groove. The user rotates the moving mechanism 7 again, and the moving mechanism 7 no longer drives the connecting rod 63 to move. At this time, the tension spring 612 fixed between each of the extension plates 611 drives the sleeve 41 to reset.

[0029] like Figure 4 As shown, in some embodiments of the present invention, the moving mechanism 7 includes a baffle 71 fixedly arranged on the connecting rod 63, a rotating shaft 72 is provided on one side of the baffle 71, and an elliptical plate 73 and a rotating handle 74 are respectively fixed at both ends of the rotating shaft 72. When the user rotates the rotating handle 74, the rotating shaft 72 is driven to rotate. The rotating shaft 72 is movably sleeved on the toner cartridge, and when the rotating shaft 72 rotates, the elliptical plate 73 is driven to rotate. At this time, the raised part of the elliptical plate 73 gradually drives the baffle 71 to displace, so that the baffle 71 drives the connecting rod 63 to displace.
