Description

Technical Field

[0001] The utility model relates to the technical field of selenium cartridges, in particular to an environmentally friendly and pollution-proof selenium cartridge component which is easy to repair. Background Art

[0002] Toner cartridges, also known as photosensitive drums, are generally composed of a basic substrate made of aluminum and photosensitive materials coated on the substrate. They are the main components of laser printers. The structure of laser printer toner cartridges mainly consists of photosensitive drums, charging rollers, transfer rollers, fixing rollers, laser generator components, etc. The integrated toner cartridge also includes a toner cartridge and a developing roller. When the toner cartridge is working, the charging roller makes the surface of the photosensitive drum carry a uniform charge. Under the irradiation of the pulsed laser, the resistance of the part of the photosensitive material on the surface of the photosensitive drum that is irradiated decreases sharply, the charge is transferred, and the charge of the part that is not irradiated is retained. On the other side, the toner is evenly distributed on the developing roller, and after passing through the toner scraper, it carries a charge with the opposite polarity to the photosensitive drum. Under electrostatic attraction, the toner is adsorbed onto the photosensitive drum, and then under the action of the stronger electrostatic field of the transfer roller, the toner is transferred to the printing paper. Finally, under the action of the fixing roller, the toner is shaped on the paper, thus completing a work flow of the toner cartridge.

[0003] Currently, when the waste toner bin of the toner cartridge assembly is cleaned, the waste toner bin is opened, causing powder to escape and be adsorbed on the photosensitive drum assembly, thereby causing a decrease in subsequent printing quality and shortening its service life.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides an environmentally friendly and pollution-proof toner cartridge assembly that is easy to repair, including an upper shell 10 and a lower shell 20 rotatably connected to the upper shell, and also includes:

[0041] A magnetic roller 110 is rotatably mounted in the upper housing 10, and a powder adding bin is provided in the upper housing 10;

[0042] The photosensitive drum assembly 210 is rotatably mounted in the lower housing 20, and a waste toner bin is also provided in the lower housing 20;

[0043] A negative pressure collection assembly 30, which is installed in the lower housing 20;

[0044] A negative pressure collection pipe 310, which is installed at the negative pressure end of the negative pressure collection assembly 30, and is placed in the waste toner bin;

[0045] A collection box 320, which is installed at the positive pressure end of the negative pressure collection assembly 30, and the collection box 320 is detachably connected to the lower housing 20;

[0046] A reciprocating assembly 40, the reciprocating assembly 40 is mounted on the inner wall of the lower housing 20 and is placed in the waste toner bin;

[0047] in,

[0048] The reciprocating end of the reciprocating assembly 40 is fixedly connected to the negative pressure collection pipe 310 via a connecting rod 470;

[0049] The end cover 50 is detachably connected to the ends of the upper shell 10 and the lower shell 20 .

[0050] Reference Figure 3 , Figure 4 and Figure 5 The negative pressure collection assembly 30 includes a negative pressure pump 330 installed on the inner wall of the lower shell 20, an air inlet pipe 340 is connected between the negative pressure end of the negative pressure pump 330 and the negative pressure collection pipe 310, and an exhaust pipe 350 is connected to the positive pressure end of the negative pressure pump 330. The end of the exhaust pipe 350 away from the negative pressure pump 330 is connected to the collection box 320.

[0051] Reference Figure 3 , Figure 4 and Figure 5 The negative pressure collection pipe 310 includes a main pipe 311 fixedly connected to one end of the air inlet pipe 340 placed in the waste powder bin, and the outer wall of the main pipe 311 is fixedly connected with evenly distributed branch pipes 312.

[0052] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The reciprocating assembly 40 includes a mounting shell 410 mounted on the bottom inner wall of the lower shell body 20, and a driving cam 420 and a mounting block 430 are fixedly mounted on the bottom inner wall of the mounting shell 410. A sliding groove is provided on the mounting block 430, and a reciprocating rod 440 is slidably connected in the sliding groove. An end of the reciprocating rod 440 close to the driving cam 420 is integrally formed with a resistance block 450, and the resistance block 450 resists the outer edge of the driving cam 420. A compression spring 460 sleeved on the outer wall of the reciprocating rod 440 is fixedly connected between the resistance block 450 and the mounting block 430. When the driving cam 420 is opened, under the elastic force of the compression spring 460, the driving cam 410 drives the resistance block 450 to move along the outer edge of the driving cam 420, thereby realizing the reciprocating movement of the reciprocating rod 440 along the mounting block 430, thereby driving the main pipe 311 to reciprocate, which helps to increase the collection range of the negative pressure collection pipe 310 and effectively reduce the cleaning dead angle in the waste powder bin.

[0053] Reference Figure 1 and Figure 2 The upper shell 10 and the lower shell 20 are rotatably connected through a rotating rod.

[0054] Reference Figure 3 , Figure 4 and Figure 5 The collection box 320 is provided with an exhaust groove, and a filter is installed in the exhaust groove. The filter is used to collect waste toner to prevent it from escaping from the collection box 320 and causing pollution to the toner cartridge assembly.

[0055] Specifically, when the environmentally friendly and pollution-proof toner cartridge assembly that is easy to repair is used, when the magnetic roller and the photosensitive drum are repaired, only the end covers 50 at the ends of the upper shell 10 and the lower shell 20 need to be removed to repair the upper shell 10 and the lower shell 20;

[0056] When cleaning the waste toner in the waste toner bin, the negative pressure pump 330 is turned on, and the negative pressure pump 330 drives the air inlet pipe 340 and the negative pressure collection pipe 310 connected thereto to generate negative pressure, and the waste toner enters the air inlet pipe 340 through the branch pipe 312, and enters the collection box 320 through the exhaust pipe 350, thereby realizing centralized collection of the waste toner without opening the upper shell 10 and the lower shell 20, and effectively preventing the waste toner from escaping and contaminating the photosensitive drum and the magnetic roller;

[0057] While the branch pipe 312 absorbs the waste toner, the driving cam 420 is opened, and under the elastic force of the compression spring 460, the driving cam 410 drives the resistance block 450 to move along the outer edge of the driving cam 420, thereby realizing the reciprocating movement of the reciprocating rod 440 along the mounting block 430, thereby driving the main pipe 311 to reciprocate, which helps to increase the collection range of the negative pressure collection pipe 310 and effectively reduce the cleaning dead corners in the waste toner bin.

[0058] All technical features in this embodiment can be freely combined according to actual needs.

[0059] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
