TECHNICAL FIELD

[0001] The utility model relates to selenium drum technical field, concretely is a buckle type selenium drum. BACKGROUND

[0002] Selenium drum is an important component in laser printer or copier, also called photosensitive drum. Selenium drum plays a crucial role in the process of laser printing or copying. It is responsible for converting laser beam into charge image and transferring the image to the printing medium. Specifically, laser beam is projected onto the surface of selenium drum through laser scanning device, causing photosensitive material to generate charge image under the action of light. Then, through the adsorption and transmission of powder ink particles to the charge image, the image is finally transferred to the printing medium, completing the printing or copying process.

[0003] The existing Chinese patent (CN221225324U) discloses a buckle type selenium drum, which includes a selenium drum body, the surface of the mounting frame is provided with a convenient maintenance mechanism, the surfaces of the mounting frame and the carbon powder bin are provided with convenient assembly mechanisms, and the surface of the cover body is provided with a carbon powder adding mechanism. The utility model not only makes the selenium drum more convenient to maintain, but also makes it easier for users to operate, which is beneficial for users to maintain the selenium drum body and mounting frame, making the selenium drum more convenient to use. At the same time, the overall stability between the carbon powder bin and the mounting frame during installation of the selenium drum is ensured, and the carbon powder in the carbon powder bin can be quickly added during use of the selenium drum, so that the carbon powder in the carbon powder bin can be supplemented in time during use of the selenium drum, ensuring normal use of the selenium drum.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments only represent some of the embodiments of the utility model, not all the embodiments.

[0022] Please refer to Figures 1-4 The utility model provides a technical scheme: a buckle type selenium drum, which comprises a selenium drum main body 1 and an upper blocking shell 5. The selenium drum main body 1 is the core structure of the selenium drum and bears key components such as a photosensitive drum and toner, and is the basis for image formation in the printing process. The upper blocking shell 5 is arranged on the inner wall of the bottom of the selenium drum main body 1. The waste powder collecting box 2 is connected to the bottom of the upper blocking shell 5. The outer wall of the waste powder collecting box 2 is in interference fit with the inner wall of the upper blocking shell 5. The upper blocking shell 5 is located at the bottom of the selenium drum main body 1 and forms interference fit with the waste powder collecting box 2, thereby playing a sealing and fixing role.

[0023] The waste powder collecting box 2 collects the waste powder scraped off in the printing process, preventing the waste powder from polluting the inside of the printer or affecting the printing quality. The electrostatic roller 12 is arranged on the inner wall of the waste powder collecting box 2. The waste powder in the waste powder collecting box is adsorbed by the electrostatic adsorption principle. The adhesive tape 13 is also arranged on the inner wall of the waste powder collecting box 2. The adhesive side of the adhesive tape 13 faces the upper blocking shell 5. As can be understood, the adhesive tape 13 is pasted on the inner wall of the waste powder collecting box, and the adhesive side faces the upper blocking shell, which is used to further prevent the waste powder from flying.

[0024] Further, the contact 4 is arranged on the outer wall of the bottom of the waste powder collecting box 2. The contact 4 is electrically connected to the electrostatic roller 12 through an electric wire. Specifically, the contact 4 is electrically connected to the contact sheet of the printer, thereby providing power supply for the electrostatic roller.

[0025] Further, the waste powder collecting box 2 is provided with an outer flange. The arc-shaped grooves 3 are arranged on the both sides of the outer flange of the waste powder collecting box 2. The outer flange is a protruding part of the waste powder collecting box, which not only increases the structural strength of the waste powder collecting box, but also provides a surface convenient for holding and operating. The arc-shaped grooves on the bottom of the selenium drum main body cooperate with the outer flange of the waste powder collecting box, thereby facilitating the removal of the waste powder collecting box 2.

[0026] Furthermore, the waste powder collection box 2 has fixing clips 11 on both sides of its bottom outer wall. The bottom of the upper baffle housing 5, above the fixing clips 11, has a fixing sleeve 6. Inside the fixing sleeve 6 is a spring 7, with a piston connecting rod 9 at its bottom end. The piston connecting rod 9 has a retaining sleeve 10 at its bottom end, which engages with the fixing clips 11. The bottom of the fixing sleeve 6 has a base plate 8, with a through hole in the center for the rod-shaped portion of the piston connecting rod 9 to pass through. The top of the spring 7 is fixed to the upper baffle housing 5, and the spring 7 exerts an upward pulling force on the piston connecting rod 9. The fixing clips 11 are engaged and fixed in the retaining sleeve 10. The spring exerts an upward pulling force on the piston connecting rod 9 and the retaining sleeve 10, further preventing the waste powder collection box 2 from detaching.

[0027] The retaining clip 11 has a small diameter at the bottom and a large diameter at the top. Once the retaining clip 11 is inserted into place, the larger diameter part at the top will prevent it from falling out.

[0028] When using the snap-on toner cartridge, the waste toner collection box 2 is connected to the upper housing 5 by an interference fit, so that the waste toner collection box 2 is snapped and fixed. At the same time, when the waste toner collection box 2 is fixed, the fixing head 11 is snapped and fixed in the sleeve 10. The spring generates an upward pulling force on the piston connecting rod 9 and the sleeve 10, which can further prevent the waste toner collection box 2 from falling off.

[0029] During the printing process, the waste toner generated is scraped off and passes through the slot in the middle of the upper housing 5 into the waste toner collection box 2 for collection. During the storage of waste toner, the adhesive side of the tape 13 is facing upwards to adhere some of the waste toner and prevent it from flying out. At the same time, the bottom of the printer drum is equipped with a contact piece that is electrically connected to the contact point 4. When the drum is powered on, the contact point 4 is also powered on, which causes the electrostatic roller 12 to generate static electricity, attracting the waste toner and effectively preventing it from flying out.

[0030] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
