Definitions

  • the present invention relates to a developing toner cartridge for an image forming apparatus of the electrophotographic principle, and more particularly to a developing toner cartridge having a powder outlet provided at the bottom. Background technique
  • a developing device for developing an electrostatic latent image formed on a photosensitive drum is provided, and the developing device applies the developing powder to the electrostatic latent image and the image is placed thereon.
  • Developing on the medium, and the developing powder consumed in the image forming process is generally provided by the developing toner cartridge, and the developing toner cartridge is usually detachably mounted in the mounting position in the developing device, and the developing powder in the developing toner cartridge is exhausted. After that, a new toner cartridge will be replaced.
  • CN 1109933C discloses a structure of a developing powder container, the specific structure of which is: a box body with a developing powder inside, a powder outlet at the bottom; a flange, which is arranged at the out Around the powder mouth; a shutter which is slidably disposed relative to the flange to close or open the powder outlet, the shutter including a support portion extending toward the flat plate and the side wall of the lower surface of the flange And a claw integrally formed with one of the supporting portions, the claw comprising a rigid portion connected to the supporting portion, an elastic portion extending outward from the rigid portion, and a guiding portion disposed at a side of the elastic portion near the flange and away from a locking portion on one side of the flange, when the guiding portion of the claw cooperates with the notch of the flange, the shutter opens the powder outlet; when the shutter is offset from the notch and the flange, the claw is used by the image
  • An object of the present invention is to provide a developing toner cartridge which can reliably realize engagement of a claw of a valve plate with a flange of a powder discharge port.
  • a developing toner cartridge comprising a casing for containing toner, a powder outlet at the bottom thereof, and a flange around the powder outlet, a shutter connected to the powder port and the flange, the opening or closing of the shutter movement, the powder outlet and the detachable group

  • Figure 3 is a schematic view showing the structure of the powder outlet when the powder opening is opened
  • Figure 4 is a schematic view showing the structure of the powder outlet when the powder outlet is closed
  • Figure 5 is a front view of the developing toner cartridge when it is in operation
  • Figure 6 is a bottom view of the structure of the powder outlet when the developing toner cartridge is in operation
  • Figure 7 is a front view of the developing toner cartridge
  • Figure 8 is a bottom view of the structure of the powder outlet when the developing toner cartridge is removed;
  • the mounting portion 7 of the image generating device for the sake of clarity, the mounting portion of Figure 1 is illustrated in detail in the drawings. 7 is a schematic structure, and the mounting portion 7 includes a stopper 1, a guide plate 3, a handle 4, a sealing sponge 8 at the toner replenishing port 10, and a toner replenishing port 10 which are engaged with the developing toner cartridge 2. Among them, the sealing sponge 8 is disposed around the toner replenishing port 10.
  • Xb indicates the direction of disengagement opposite to Xa
  • Ya indicates that the developer cartridge 2 is inserted into the mounting portion.
  • Yb indicates the direction in which the developing cartridge is taken out opposite to Ya.
  • the developing toner cartridge 2 includes a main body 21 for containing toner, an upper cover 22, a shutter 5 and a snap member 6 provided at the bottom of the developing toner cartridge 2, and a second end portion of the developing toner cartridge.
  • the side wall of the main body 21 is provided with a push rod 21a near the bottom, and the bottom is provided with a powder outlet 29, and a flange 27 is arranged around the powder outlet 29, and the flange 27 is disposed on the side wall near the powder outlet.
  • the snap member 6 is hinged to the outer side wall of the shutter 5 via a hinge 51.
  • the outer side wall of the shutter 5 is further provided with a limiting post 52 to limit the range in which the latching member 6 is rotated to one side.
  • the shutter 5 is slidable along the flange 27, so that the push rod 21a controls the snap member 6 to rotate about the hinge shaft 51 to realize the opening of the shutter 5 And the effect of closing the powder outlet 29.
  • a buckle la is provided to limit the range in which the fastening member 6 is rotated to the other side.
  • the entire developing toner cartridge 2 works as follows: Initially, the powder supply port 29 is closed. The developing toner cartridge 2 is inserted into the mounting portion 7 in the Ya direction, and then the handle 4 (see FIG. 1) is pulled to move the developing toner cartridge 2 in the Xa direction on the guide plate 3, when the shutter 5 is in contact with the sealing sponge 8. When the force of the boss 27a and the groove 5a cooperate with the frictional force of the shutter 5 and the sponge 8, the shutter 5 and the toner cartridge continue to move along the Xa direction. When the shutter 5 contacts the limiting block 1, the brake is opened.
  • the plate 5 stops moving, and the developing toner cartridge 2 continues to move in the Xa direction.
  • the powder discharging port 29 is opened and docked with the toner replenishing port 10 shown in Fig. 1, and at the same time, the push rod 21a pushes one end of the buckle member 6.
  • the developing toner cartridge 2 enters the supplementary toner working state; when the handle 4 is pulled to move the developing toner cartridge 2 on the guiding plate 3 in the Xb direction, The latching member 6 is still in the state of holding the buckle position la, the shutter 5 and the latching member 6 are stationary relative to the buckle position la, and the developing toner cartridge 2 continues to move along the Xb, the powder discharging port is closed, and then the push rod 21a is pushed.
  • the other end of the fastening member 6 is rotated clockwise around the hinge 51 and buckled
  • the toner cartridge 2 and the shutter 5 and the snap member 6 are moved together along the Xb until the toner cartridge 2 and the stopper 1 are completely separated, the toner cartridge 2 can be taken out in the Yb direction.
  • the snap member 6 and the shutter 5 are separated, and even if the snap member 6 is broken, the scraping of the shutter 5 is not affected; in this embodiment, the snap member is made of a tough POM.
  • the shape of the cross section may be rectangular or "H" type.
  • the present invention has the following advantages: the detachable assembly of the fastening member 6 is disposed on the valve plate 5, and the engagement of the fastening member 6 with the flange 7 can be easily controlled and reliably realized; At the same time, since the snap member 6 is a separate member, if it is damaged, only the snap member 6 can be replaced without having to replace the entire shutter 5, thereby reducing the cost of use.

Abstract

L’invention concerne une cartouche de toner comprenant un corps de cartouche contenant du toner et muni d’une ouverture d’écoulement du toner formée dans sa face inférieure. Une bride est disposée autour de l’ouverture d’écoulement du toner. Un obturateur est conçu pour coulisser par rapport à la bride et pour se déplacer entre une position fermée dans laquelle l’ouverture d’écoulement du toner est fermée et une position ouverte dans laquelle l’ouverture d’écoulement du toner est ouverte. Une griffe est installée de manière détachable sur l’obturateur.
