Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically to a printer toner cartridge. Background Technology

[0002] A toner cartridge is a consumable used in laser printers and multifunction copiers, primarily to store toner, a solid powdery substance. A toner cartridge, also known as a toner box or toner container, is a copying consumable product provided to laser printers and multifunction copiers. Toner is a solid powdery substance used to form text and images during the printing process.

[0003] Patent CN221378485U discloses a printer toner with a toner stirring function. It includes a toner cartridge with a toner chamber inside. A rotating shaft is mounted on the inner wall of the toner chamber via a bearing. Several stirring blades are evenly mounted on the surface of the rotating shaft. This device can perform secondary stirring of the toner by the rotating blades while the stirring blades are stirring. It has a simple structure, more thorough stirring, and prevents the toner from solidifying during long-term standing. At the same time, a cleaning scraper is provided on the outer surface of the fixed frame. The cleaning scraper is in close contact with the inner surface of the toner chamber, thereby preventing a large amount of toner from sticking to the inner wall of the toner chamber.

[0004] However, this device uses a second motor and a micro motor to perform multiple stirrings on the toner in the toner chamber, and then uses a first motor in conjunction with an external cleaning scraper on the fixed frame to clean the walls of the toner chamber. However, the toner cartridge uses multiple sets of motors and several micro motors to drive the operation of various structural components. Since the longitudinal position of the rotating blades in the fixed frame and the lateral position of the stirring blades are fixed, it is difficult to fully stir the toner inside the toner chamber. At the same time, the use of too many motors also significantly increases the power consumption of the printer toner cartridge during use. Therefore, a printer toner cartridge is proposed to solve the problem that the toner in the existing toner cartridge is prone to clumping, which affects the print quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a printer toner cartridge that solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a printer toner cartridge, comprising a toner cartridge body, a toner cavity inside the toner cartridge body, a planetary gear set inside one side of the toner cavity, a motor fixedly connected to one side of the toner cartridge body, a rotating rod inside the toner cavity, several stirring plates fixedly connected to the outside of the rotating rod, a movable groove inside one side of the rotating rod, a return spring inside the movable groove, a limit groove on the left side of the movable groove, a limit plate inside the limit groove, a drive groove on the left inner wall of the toner cartridge body, two centrally symmetrical trapezoidal blocks inside the drive groove, and a rotating plate between the trapezoidal blocks.

[0007] Preferably, the planetary gear set includes a limiting groove formed on one side of the toner chamber, an internal gear ring rotatably connected inside the limiting groove, and a sun gear and multiple pinions arranged in the middle of the limiting groove.

[0008] Preferably, the motor extends through the limiting slot and is fixedly connected to the sun gear, the pinion is mounted in the limiting slot using a rotating shaft, and the internal gear ring, sun gear and pinion are all meshed.

[0009] Preferably, two scrapers are symmetrically fixedly connected to the side of the internal gear ring facing the toner chamber. The scrapers are in contact with the inner wall of the toner chamber, and several stirring plates are fixedly connected to the opposite side of the scrapers.

[0010] Preferably, the output shaft of the motor passes through the inner cavity of the movable slot, and the two ends of the return spring are fixedly connected to the movable slot and the output shaft of the motor, respectively.

[0011] Preferably, one end of the limiting plate is fixedly connected to the output shaft of the motor, the limiting plate and the limiting groove are slidably connected, and the rotating rod passes through the inner cavity of the drive groove and is fixedly connected to the rotating plate.

[0012] Preferably, a sealing plate is provided on one side of the internal gear ring, and the sealing plate is fixedly connected to the output shaft of the motor.

[0013] This printer toner cartridge uses a motor that, in conjunction with a planetary gear set and a limiting plate in a limiting slot, drives a rotating rod to rotate, which in turn drives a stirring plate to rotate. As the rotating plate rotates past a centrally symmetrical trapezoidal block, the rotating rod and stirring plate are pushed to the right. With the help of a return spring, they move back and forth, achieving the purpose of thoroughly stirring the toner and solving the problem of toner clumping in existing toner cartridges, which affects print quality.

[0014] The printer toner cartridge uses a motor to drive the sun gear on the output shaft, which in turn drives the pinion on the rotating shaft to rotate the internal gear ring in the limiting groove along with the scraper. This causes the stirring plate on the scraper to rotate in the opposite direction to the stirring plate outside the rotating rod, achieving multi-directional stirring and improving the stirring effect. At the same time, the scraper can be used to scrape the cavity wall of the toner chamber to prevent a large amount of toner from sticking. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figure 1-5A printer toner cartridge includes a toner cartridge body 1, a toner cavity 2 inside the toner cartridge body 1, a planetary gear set 3 inside one side of the toner cavity 2, a motor 4 fixedly connected to one side of the toner cartridge body 1, a rotating rod 6 inside the toner cavity 2, several stirring plates 7 fixedly connected to the outside of the rotating rod 6, a movable groove 8 on one side of the rotating rod 6, a return spring 9 inside the movable groove 8, a limiting groove 11 on the left side of the movable groove 8, a limiting plate 10 inside the limiting groove 11, a driving groove 12 on the left inner wall of the toner cartridge body 1, two centrally symmetrical trapezoidal blocks 13 inside the driving groove 12, and a rotating plate 14 between the trapezoidal blocks 13.

[0023] Furthermore, the planetary gear set 3 includes a limiting groove 301 opened on one side of the toner chamber 2. An internal gear ring 302 is rotatably connected inside the limiting groove 301. A sun gear 303 and a plurality of pinions 304 are arranged in the middle of the limiting groove 301.

[0024] Furthermore, the motor 4 extends through the limiting slot 301 and is fixedly connected to the sun gear 303. The pinion 304 is set in the limiting slot 301 by means of the rotating shaft 305. The internal gear ring 302, the sun gear 303 and the pinion 304 are all meshed.

[0025] Furthermore, two scrapers 5 are symmetrically fixedly connected to the side of the internal gear ring 302 facing the toner chamber 2. The scrapers 5 are in contact with the inner wall of the toner chamber 2, and several stirring plates 7 are fixedly connected to the opposite side of the scrapers 5.

[0026] Furthermore, the output shaft of the motor 4 passes through the inner cavity of the movable groove 8. The two ends of the return spring 9 are fixedly connected to the movable groove 8 and the output shaft of the motor 4, respectively. The motor 4 drives the sun gear 303 on the output shaft, which, together with the pinion 304 on the rotating shaft 305, drives the internal gear ring 302 in the limiting rotating groove 301 to rotate together with the scraper 5. This causes the stirring plate 7 on the scraper 5 to rotate in the opposite direction to the stirring plate 7 outside the rotating rod 6, achieving the purpose of multi-directional stirring and improving the stirring effect. At the same time, the scraper 5 can be used to scrape the cavity wall of the toner chamber 2 to prevent a large amount of toner from sticking.

[0027] Furthermore, one end of the limiting plate 10 is fixedly connected to the output shaft of the motor 4, the limiting plate 10 and the limiting groove 11 are slidably connected, and the rotating rod 6 passes through the inner cavity of the drive groove 12 and is fixedly connected to the rotating plate 14.

[0028] Furthermore, a sealing plate 15 is provided on one side of the internal gear ring 302. The sealing plate 15 is fixedly connected to the output shaft of the motor 4. The sealing plate 15 is used to shield the internal gear ring 302 to prevent carbon powder from entering the interior and affecting the operation of the planetary gear set 3.

[0029] Working principle: When using this printer toner cartridge, the motor 4, in conjunction with the planetary gear set 3 and the limiting plate 10 in the limiting groove 11, drives the rotating rod 6 to rotate, which in turn drives the stirring plate 7 to rotate, along with the rotating plate 14. When the rotating plate 14 rotates past the centrally symmetrical trapezoidal block 13, the rotating rod 6 and the stirring plate 7 are pushed to the right, and with the help of the return spring 9, they move back and forth left and right, achieving the purpose of moving and stirring the toner. This solves the problem of toner easily clumping in existing toner cartridges, which affects print quality.
