Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a toner stirring structure for a printer toner box. Background Art

[0002] A printer is one of the output devices of a computer, used to print the computer processing results on related media. The printer toner cartridge is one of the important components of the printer and is used to store toner. Most existing toner cartridges use a stirring device to stir the toner during use, allowing the stirred toner to contact the electrostatic roller. Then, after the electrostatic roller, adsorption roller and toner drum rotate, toner particles corresponding to the pattern appear on the surface of the toner drum. However, the existing toner stirring structure stirs the toner through a spring sheet. In this way, when the spring sheet ages and loses its elasticity after long-term use, the toner is unevenly stirred, which leads to poor printing quality.

[0003] For example, a Chinese utility model patent disclosed in the Chinese patent publication number CN215867506U and with an authorization announcement date of February 18, 2022 discloses a printer toner cartridge with a toner stirring structure, including a toner cartridge body, a toner chamber and a transmission chamber in the middle of the toner cartridge body, the inner cavity of the toner chamber is movably connected to a rotating tube, a yield groove is provided in the middle of the rotating tube, and a splint is fixedly installed at both the front and rear ends of the rotating tube, and a transmission gear ring is fixedly installed on the front side of the splint.

[0004] However, in actual use, the above-mentioned toner cartridge stirring structure increases the elasticity of the spring plate by lengthening the protruding part of the spring plate, ensuring that the toner can be smoothly adsorbed on the surface of the electrostatic roller, thereby improving the printing quality of the device. However, the spring plate is fixed to the rotating shaft by winding, which will cause the spring plate to shake when stirring the toner, thereby affecting the spring plate's stirring of the toner, causing uneven stirring of the toner, and ultimately resulting in poor quality of the products printed by the printer. Utility Model Content

[0005] The utility model aims to provide a toner stirring structure for a printer toner cartridge, so as to solve the problem that the existing toner cartridge stirring structure does not stir the toner sufficiently.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a toner stirring structure for a printer toner cartridge, comprising a toner cartridge body, a toner chamber and a transmission chamber, a toner chamber being provided inside the toner cartridge body, a rotating shaft being rotatably connected inside the toner chamber, two clamping members being provided in the middle of the rotating shaft, threaded grooves being provided at both ends of the clamping members, nuts being threadedly connected to the threaded grooves of the clamping members, a plurality of positioning pins being fixedly connected to both ends of the rotating shaft, a plurality of positioning holes being provided in the middle of the clamping member, the positioning pins being movably connected to the positioning holes, and two stirring blades being provided between the two clamping members.

[0007] Preferably, a plurality of clamping blocks are fixedly connected to both ends of the clamping member, and a plurality of clamping slots are provided on one end of the clamping member, and the clamping blocks are clamped in the clamping slots.

[0008] Preferably, the carbon powder box body is provided with a transmission cavity adjacent to the carbon powder cavity.

[0009] Preferably, an electrostatic roller is provided above the carbon powder chamber in the transmission chamber, and the electrostatic roller is rotatably connected to the carbon powder chamber body.

[0010] Preferably, an adsorption roller is provided in the transmission cavity on the right side of the electrostatic roller, and the adsorption roller is rotatably connected to the carbon powder and the body.

[0011] Preferably, a toner cartridge is provided in the transmission cavity on the right side of the adsorption roller, and the toner cartridge is rotatably connected to the carbon powder and the body.

[0012] Preferably, a de-charge roller is provided below the toner cartridge in the transmission cavity, and the de-charge roller is rotatably connected to the toner cartridge body.

[0013] Preferably, the carbon powder and the body are provided with a powder adding hole at one end of the carbon powder chamber.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model clamps the stirring blade by arranging two clamping members, and then clamps the two clamping members by a nut, thereby fixing the stirring blade to the column. By arranging a positioning pin on the rotating shaft and opening a positioning hole on the clamping member, the clamping member can be firmly connected to the rotating shaft during the stirring of the carbon powder by the stirring blade, and there will be no slipping. In addition, by arranging blocks at both ends of the clamping member and opening a slot on the stirring blade, the clamping block can be clamped in the slot when the stirring blade is installed on the clamping member. In this way, the stirring blade is firmly fixed between the two clamping members when stirring the carbon powder, and there will be no shaking. In this way, the stirring blade can stir the carbon powder more fully, and there will be no uneven stirring. It is very practical. BRIEF DESCRIPTION OF THE DRAWINGS

The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figure 1-8 The utility model provides a technical solution: a toner stirring structure for a printer toner cartridge, comprising a toner cartridge body 1, a toner chamber 2 and a transmission chamber 3. The toner cartridge body 1 is provided with a toner chamber 2, a rotating shaft 4 is rotatably connected in the toner chamber 2, two clamping members 5 are provided in the middle of the rotating shaft 4, both ends of the clamping members 5 are provided with threaded grooves 6, the clamping members 5 are threadedly connected with nuts 7 at the threaded grooves 6, a plurality of positioning pins 8 are fixedly connected at both ends of the rotating shaft 4, a plurality of positioning holes 9 are provided in the middle of the clamping members 5, the positioning pins 8 are movably plugged into the positioning holes 9, and two stirring blades 10 are provided between the two clamping members 5.

[0027] When the stirring blade 10 needs to be installed in the toner cartridge body 1, a clamping piece 5 is first installed on the rotating shaft 4 so that the positioning hole 9 on the clamping piece 5 is plugged into the positioning pin 8 on the rotating shaft 4, and then the stirring blade 10 is installed on the clamping piece 5. After the stirring blade 10 is installed on both ends of the clamping piece 5, another clamping piece 5 is installed on the rotating shaft 4, and the positioning hole 9 on the clamping piece 5 is plugged into the positioning pin 8 on the rotating shaft 4. Then the nut 7 is installed to the position where the thread groove 6 is provided at both ends of the clamping piece 5. In this way, the two clamping pieces 5 are firmly fixed on the rotating shaft 4, and then the stirring blade 10 is firmly fixed. In this way, when the stirring blade 10 stirs the toner, the clamping piece 5 will not slip on the rotating shaft 4, and the stirring blade 10 will not shake during the stirring process, so that the stirring blade 10 can stir the toner more fully.

[0028] like Figure 5-8 As shown, a plurality of blocks 11 are fixedly connected at both ends of the clamping member 5, and a plurality of slots 12 are provided at one end of the clamping member 5, and the blocks are engaged with the slots 12. In this embodiment, by providing the blocks 11 on the clamping member 5 and opening the slots 12 on the stirring blade 10, when the stirring blade 10 is installed between the two clamping members 5, the blocks 11 will be engaged with the slots 12, so that the stirring blade 10 will be firmly connected to the clamping member 5 during the stirring process, and will not fall off or shake.

[0029] like Figure 2 As shown, the toner cartridge body 1 is provided with a transmission cavity 3 adjacent to the toner cavity 2. In this embodiment, the toner cartridge body 1 is provided with the transmission cavity 3 so that the toner can be smoothly transferred to the paper.

[0030] like Figure 2 As shown, an electrostatic roller 13 is provided above the toner chamber 2 in the transmission chamber 3. The electrostatic roller 13 is rotatably connected to the body of the toner chamber 2. In this embodiment, the design of the electrostatic roller 13 can adsorb the toner in the toner chamber 2 to facilitate the transfer of the toner to the paper.

[0031] like Figure 2 As shown, an adsorption roller 14 is provided on the right side of the electrostatic roller 13 in the transmission chamber 3. The adsorption roller 14 is connected to the carbon powder and the main body in rotation. In this embodiment, when the electrostatic roller 13 adsorbs the carbon powder, the laser generating device provided in the rotating chamber of the toner cartridge body 1 will irradiate the adsorption roller 14, so that the irradiated part of the adsorption roller 14 is charged. At this time, when the charged part of the adsorption roller 14 contacts the electrostatic roller 13, the carbon powder on the electrostatic roller 13 will be transferred to the adsorption roller 14.

[0032] like Figure 2As shown, a toner cartridge 15 is provided in the transmission chamber 3 on the right side of the adsorption roller 14. The toner cartridge 15 is rotatably connected to the toner and the body. In this embodiment, after the toner is transferred to the adsorption roller 14, the laser printing device irradiates the toner cartridge 15 to charge the toner cartridge 15. At this time, when the toner on the adsorption roller 14 contacts the toner cartridge 15, the toner will be transferred to the toner cartridge 15. When the toner cartridge 15 contacts the paper, the toner will be transferred to the paper.

[0033] like Figure 2 As shown, a de-charge roller 16 is provided below the toner cartridge 15 in the transmission cavity 3 , and the de-charge roller 16 is rotatably connected to the toner cartridge body 1 . In this embodiment, the de-charge roller 16 is designed to de-charge the charged parts of the toner cartridge 15 .

[0034] like Figure 1 As shown, a powder adding hole 17 is provided at one end of the toner chamber 2 . In this embodiment, since the toner in the toner cartridge body 1 will be consumed after the printer has been printing for a long time, people can add toner to the toner cartridge body 1 through the powder adding hole 17 .

[0035] Working principle: When in use, when it is necessary to install the stirring blade 10 in the toner cartridge body 1, first install a clamping piece 5 on the rotating shaft 4, and make the positioning hole 9 on the clamping piece 5 and the positioning pin 8 on the rotating shaft 4 plug together, then install the stirring blade 10 on the clamping piece 5, and make the clamping block 11 on the clamping piece 5 snap into the clamping groove 12 provided on the stirring blade 10, after the stirring blade 10 is installed on both ends of the clamping piece 5, install the other clamping piece 5 on the rotating shaft 4, and make the positioning hole 9 on the clamping piece 5 and the positioning pin 8 on the rotating shaft 4 plug together. At the same time, the block 11 on the clamping piece 5 is clamped into the slot 12 of the stirring blade 10, and then the nut 7 is installed to the position where the thread groove 6 is provided at both ends of the clamping piece 5, so that the two clamping pieces 5 are firmly fixed on the rotating shaft 4, and then the stirring blade 10 is firmly fixed, so that the stirring blade 10 will not slip on the rotating shaft 4 when stirring the toner, and the stirring blade 10 will not shake during the stirring process. When the stirring blade 10 is installed, the rotating shaft 4 can be installed in the toner cartridge body 1, and then through The powder adding hole 17 adds toner to the toner chamber 2 in the toner cartridge body 1. At this time, the toner cartridge body 1 filled with toner can be installed in the printer. Driven by the driving motor in the printer, the rotating shaft 4, electrostatic roller 13, adsorption roller 14, toner drum 15 and de-electrification roller 16 in the toner cartridge body 1 will start to rotate. During this process, the rotating shaft 4 drives the stirring blade 10 to stir the toner, and the electrostatic roller 13 adsorbs the stirred toner. At this time, the laser generating device provided in the rotating chamber of the toner cartridge body 1 will irradiate the adsorption roller 14. The irradiated part of the adsorption roller 14 is charged. When the charged part of the adsorption roller 14 contacts the electrostatic roller 13, the toner on the electrostatic roller 13 will be transferred to the adsorption roller 14. Then the laser printing device charges the toner drum 15 in the same way. When the toner on the adsorption roller 14 contacts the toner drum 15, the toner will be transferred to the toner drum 15. When the toner drum 15 contacts the paper, the toner will be transferred to the paper, thereby achieving the purpose of printing. A de-charge roller 16 is set under the toner drum 15 to de-charge the charged part of the toner drum 15.
