Background

An electrophotographic image forming apparatus generally has an image processing unit and a toner cartridge detachably mounted to the image processing unit, the toner cartridge containing a developer (toner) such as toner for developing an electrostatic latent image formed on the image processing unit to form a visible image on a medium such as paper. Since the developer as a consumable product needs to be constantly replenished into the electrophotographic type image forming apparatus, the developing unit detachably mounted to the electrophotographic type image forming apparatus is often loaded with only a certain amount of developer, and therefore, the toner cartridge needs to be frequently replaced.

There is a toner cartridge, both sides of which are provided with guide rails, and when the toner cartridge is mounted to an electrophotographic image forming apparatus, the guide rails are engaged with a toner cartridge receiving chamber in the electrophotographic image forming apparatus along with the movement of the toner cartridge, so that the toner cartridge receiving chamber moves toward the toner cartridge in a vertical direction, thereby achieving the engagement of a toner discharge opening of the toner cartridge with a toner inlet opening of the toner cartridge receiving chamber. However, since the guide rails are disposed on both sides of the toner cartridge, once the toner cartridge is tilted or the two sliding protrusions in the toner cartridge receiving cavity, which are engaged with the guide rails, are not at the same horizontal position during the installation process, the sliding protrusions may be locked with the guide rails of the toner cartridge, and the toner cartridge cannot be smoothly installed in the electrophotographic image forming apparatus. In addition, the powder discharge port of the existing carbon powder cylinder is in rigid butt joint with the powder inlet of the powder cylinder receiving cavity, and the sealing and the positioning of the powder outlet are influenced.

Disclosure of Invention

The invention aims to provide a carbon powder barrel which is simple in structure and smooth in assembly process.

In order to achieve the above object, the present invention provides a toner cartridge detachably mountable in an electrophotographic image forming apparatus including a toner receiving member provided with a toner inlet. The carbon powder barrel comprises a barrel main body and an end cover, wherein the end cover is arranged at one end of the barrel main body, a powder discharging opening which can be communicated with the powder inlet is formed in the bottom of the end cover, a driving force receiving part is arranged on the outer surface of one end, close to the end cover, of the barrel main body, a gate is arranged on the end cover, and the gate is used for opening and closing the powder discharging opening. Only one of two opposite sides of the end cover is provided with an unsealing guide rail, the unsealing guide rail is provided with a guide inclined plane, and the guide inclined plane is inclined relative to the central shaft of the cylinder main body; the guide inclined plane is arranged obliquely from bottom to top along the axial direction of the cylinder main body from one end far away from the driving force receiving part to one end close to the driving force receiving part; a longitudinal plane perpendicular to the central axis of the cartridge body and passing through the powder discharge port intersects the guide ramp. The gate is provided with an elastic extrusion part; the guide slope guides the toner receiving member to move in the vertical direction toward the toner discharge opening until the toner receiving member abuts against the shutter in accordance with the mounting operation of the toner cartridge.

According to the scheme, when the carbon powder cylinder is installed in the electronic photography type imaging device, one matching protrusion of the carbon powder receiving piece moves upwards along the guide inclined plane of the unsealing guide rail along with the forward movement of the carbon powder cylinder so as to open the powder inlet of the electronic photography type imaging device, and therefore the connection and the communication between the powder discharge port of the carbon powder cylinder and the powder inlet of the powder cylinder receiving cavity are achieved. As the carbon powder barrel is only provided with the unsealing guide rail on one side, the phenomenon that the matching bulges on the two sides are not at the same horizontal position or incline to cause the blockage of the carbon powder barrel in the installation process can be avoided. After the carbon powder receiving piece is butted with the powder discharging opening, the contact between the carbon powder receiving piece and the flashboard is flexible contact, therefore, the position of the carbon powder receiving piece is easier to control, for example, when the carbon powder receiving piece is pulled to a higher position by a guide rail, the compression degree of the elastic extrusion part is larger, and when the carbon powder receiving piece is pulled to a lower position by the guide rail, the compression degree of the elastic extrusion part is small. Because elastic deformation can be carried out to elasticity extrusion portion atress, so even the carbon powder receives piece slope, the setting up of elasticity extrusion portion makes the flashboard can adapt to the state change that the carbon powder received piece, receives the piece with the carbon powder all the time and carries out good butt joint, and the carbon powder receives the piece and arranges the powder mouth and can keep good encapsulated situation, prevents that the carbon powder from revealing from the butt joint position. Meanwhile, due to the arrangement of the elastic pressing part, the carbon powder receiving piece can be more stably supported at the combination position of the carbon powder receiving piece and the powder discharging opening.

Preferably, the shutter comprises a plate body and a resilient seal member on a side of the plate body facing the toner receiving member and located opposite the toner receiving member, the resilient pressing portion being located on the resilient seal member.

Therefore, when the carbon powder receiving piece is jointed with the powder discharge opening, the top end of the carbon powder receiving piece abuts against the elastic sealing piece, and when the carbon powder receiving piece inclines, the elastic sealing piece can deform adaptively, so that the top end of the carbon powder receiving piece is kept to be well sealed all the time.

Preferably, the shutter includes a plate body and a resilient seal member on a side of the plate body facing away from the toner receiving member, the resilient pressing portion being on the resilient seal member.

Therefore, the elastic sealing piece is positioned between the plate body and the end cover, when the carbon powder receiving piece inclines, acting force can be applied to the plate body, and the elastic sealing piece is arranged between the plate body and the end cover, so that the plate body can follow the change of the position of the carbon powder receiving piece, and the state of tight butt joint between the plate body and the carbon powder receiving piece is always kept.

The further scheme is that a mounting groove is formed in the side wall, back to the carbon powder receiving piece, of the plate body, an opening is formed in the bottom of the mounting groove, the opening penetrates through the plate body in the vertical direction, and the elastic sealing piece is mounted in the mounting groove; the elastic sealing piece comprises a moving piece and a sealing ring, and the sealing ring is arranged on one side of the moving piece, which is back to the carbon powder receiving piece; the moving part comprises a main body part and a limiting part, the limiting part protrudes outwards from the side wall of the main body part, the limiting part is abutted to the bottom wall of the mounting groove, the main body part extends downwards into the opening, the butt joint groove is formed in the lower side of the main body part, and the butt joint groove can be engaged with the carbon powder receiving part.

Therefore, the carbon powder receiving piece abuts against the elastic sealing piece, when the carbon powder receiving piece inclines, acting force can be applied to the moving piece, only the elastic sealing piece part and the carbon powder receiving piece are subjected to adaptive position adjustment, the position of the whole flashboard cannot be changed, and a better sealing effect can be achieved.

Preferably, the gate is made of an elastic material.

Therefore, the whole gate is an elastic part, and an elastic sealing part is not required to be additionally arranged, so that the assembly process is reduced, and the assembly efficiency is improved.

Preferably, the end cap is provided with a support on the side opposite the unsealing guide, the support comprising a support surface extending in the axial direction of the cartridge body.

Therefore, when the carbon powder barrel is installed in place, the powder inlet of the electronic photography type imaging device is opened, the matching protrusion moves upwards to the limit position, and the matching protrusion on the side opposite to the unsealing guide rail is supported by the supporting surface, so that the positioning stability of the carbon powder receiving piece in the electronic photography type imaging device is ensured.

Further, the support member further includes a stop surface extending from an end of the support surface remote from the driving force receiving portion toward a lower side of the support surface.

It can be seen that the stop surface serves to prevent the co-operating projections on the same side from moving to the underside of the stop surface, so that no supporting action is possible.

Preferably, the stop surface and the support surface are connected by an arc surface.

It follows that smooth movement of the mating projection above the support surface is ensured.

It is preferable that an end of the guide slope near the driving force receiving portion is higher than an intersection position of the longitudinal plane and the guide slope.

Therefore, the matching protrusion can be moved to a position where the powder discharge port of the carbon powder cylinder can be jointed with the powder inlet of the powder cylinder receiving cavity along the unsealing guide rail, and the matching protrusion is prevented from being separated from the unsealing guide rail due to the fact that the unsealing guide rail is not long enough.

One preferred scheme is that the end cover comprises an outer cover and a shell, the outer cover is covered outside the shell, the powder discharging port is located on the shell, the gate is detachably mounted on the shell, the shell is provided with a sliding groove extending along the axial direction of the cylinder main body, and the gate is in sliding fit with the sliding groove.

Therefore, when the carbon powder barrel is assembled, the gate is clamped in the electronic photography type imaging device, the carbon powder barrel is continuously pushed forwards, the gate slides relative to the sliding groove, and the powder discharging opening is opened.

In a further aspect, the unsealing guide rails are provided on the side walls of the housing.

The further proposal is that the unsealing guide rail is arranged on the outer cover.

The further proposal is that the unsealing guide rail is arranged on a first side wall of the outer cover, and the first side wall is connected with a first supporting wall, a second supporting wall and a third supporting wall; first support wall and first lateral wall parallel arrangement, second support wall and third support wall all connect between first support wall and first lateral wall, unseal the guide rail setting on first support wall and outwards bulge from first support wall, unseal the guide rail and lie in the space that is enclosed by first support wall, second support wall and third support wall. The second supporting wall is located at one end, close to the driving force receiving portion, of the unsealing guide rail, the third supporting wall is located above the unsealing guide rail, and a first opening is formed in the position, opposite to the first supporting wall, of the first side wall. The first supporting wall and the first side wall are provided with a second opening at one side opposite to the unsealing guide rail and the second supporting wall, the first supporting wall and the first side wall are provided with a third opening at the lower side of the unsealing guide rail, and the second opening is connected with the third opening.

Therefore, the opening guide rail is provided with the end cover, and when the matching protrusion moves upwards along the opening guide rail, the friction force between the carbon powder receiving piece and the first side wall of the outer cover can be reduced due to the arrangement of the first opening, so that the installation process of the carbon powder cylinder is smoother.

The further scheme is that the gate is provided with a powder outlet in a penetrating manner in the vertical direction, and when the gate is positioned at an opening position, the powder outlet is opposite to and communicated with the powder outlet.

One preferred scheme is that the carbon powder receives piece includes main part, two bracing pieces and two cooperation archs, goes into the setting of powder mouth and runs through the main part along vertical direction on the main part, and two bracing pieces set up the both sides at the main part relatively, and the cooperation is protruding to be set up with the bracing piece one-to-one, cooperation protruding setting on the relative lateral wall of two bracing pieces and with guide inclined plane sliding fit.

Therefore, the carbon powder barrel is only provided with the unsealing guide rail on one side, so that the phenomenon that the carbon powder barrel is clamped in the installation process due to the fact that the matching protrusions on the two sides are not in the same horizontal position or the carbon powder barrel inclines in the installation process can be avoided.
