Description

toner container

technical field

The utility model relates to a toner container which is detachably installed on electrostatic imaging equipment such as laser printers, copiers and fax machines, so as to supply toner for the electrostatic imaging equipment.

Background technique

Traditional electrostatic imaging equipment, such as laser printers, copiers or fax machines, typically use fine particle toners. Toner is very fine particles and is usually stored in a separate container from the imaging device. The toner container is in a sealed state when it is not mounted on the electrostatic image forming device, and after being installed in the electrostatic image forming device, the toner outlet of the toner container is opened to supply toner to the electrostatic image forming device.

FIG. 13 shows a conventional toner container. The toner container mainly includes a container main body 6 with an outlet at one end and a connecting piece 7 arranged at the outlet end of the container main body 6 . The structure of the connector 7 is shown in FIG. 14 , including a locking protrusion 71 disposed at the front end, a sealing portion 72 and a driving force transmission portion 73 . The sealing part 72 is equipped with a sealing ring 72a made of elastic material such as rubber. The outer diameter of the sealing ring 72a is larger than the inner diameter of the outlet of the container body to seal the outlet of the container body. The driving force transmission part 73 is two thin plates arranged radially opposite to each other. When the toner container is in a sealed state as shown in FIG. 13 , the sealing ring 72 a seals the outlet of the container main body, the driving force transmission part 73 is located inside the container main body 6 , and the locking protrusion 71 is located outside the container main body 6 .

When the toner container is installed in the electrostatic image forming device, the toner container is pushed by the electrostatic image forming device, first moves in the direction indicated by arrow a in FIG. In the locking hole 81a, the side 71a of the locking protrusion 71 abuts against the side of the locking hole 81a; then, the container main body 6 is pushed back and moves in the opposite direction of the arrow a, and since the locking protrusion 71 has been locked by the driving part 81 at this time, the connection The member 7 is partially pulled out of the container main body 6, and the outlet of the container main body 6 is opened so that the toner in the container main body 6 is supplied to the electrostatic image forming apparatus through the outlet, as shown in FIG. 15 . In FIG. 15, electrostatic image forming apparatuses not belonging to the structure of the toner container are indicated by two-dot chain lines. The drive portion 81 of the electrostatic image forming apparatus is rotatably supported by a bearing or the like, and driven to rotate by a motor of the electrostatic image forming apparatus. During printing, the connecting member 7 locked by the driving part 81 rotates together with the driving part 81 . After the connector 7 idles for a certain angle, one side 73a of the driving force transmission part 73 abuts against the driving force receiving part provided inside the outlet of the container main body, thereby driving the container main body 6 to rotate together, so that the toner in the container main body 6 moves toward the Electrostatic imaging equipment supply. When the toner container needs to be resealed, the tappet 82 of the electrostatic image forming device pushes the connecting member 7 back to the outlet of the container main body 6 in the direction opposite to the arrow a in FIG. 15 .

In the electrostatic imaging device suitable for the above-mentioned toner container, first lock the connecting piece of the toner container, and then move the main body of the container away from the connecting piece to open the powder outlet. That is, after locking the connecting part of the toner container, moving the main body of the container away from the connecting part is a necessary procedure of the electrostatic image forming apparatus. However, the outlet of the toner container and the sealing ring on the connector form an interference fit to achieve sealing, which requires relatively large driving force when the electrostatic imaging device moves the container main body to open the toner outlet. Whereas, the mechanism for moving the container main body is mechanically incorporated in the electrostatic image forming apparatus, and is operated by the user when installing the toner container. This makes it laborious for the user to install the toner container and is inconvenient to operate; moreover, the mechanism for moving the main body of the container is easily damaged due to the large force. These problems are more pronounced for large-capacity toner containers.

Contents of the invention

The main purpose of the utility model is to provide a toner container that is easy to operate, labor-saving to install, and beneficial to protect electrostatic imaging equipment;

In order to achieve the above purpose, the toner container provided by the utility model includes a container main body, a connecting piece, a guiding piece and a pressing mechanism. The main body of the container is used to accommodate the toner, and one end of the container body is provided with an opening of the force-receiving part. The connecting piece and the opening of the force-receiving part are sealed and slidably matched in the axial direction. The front end is provided with a driving force receiving part for receiving the driving force of the electrostatic imaging device, and the rear end is a cylindrical structure. The rear end of the guide is provided with an engaging portion axially engaged with the cylindrical structure of the connector and the opening of the force-receiving portion of the container body. The pressing mechanism is arranged between the container main body and the guide part, so as to force the connecting part to protrude relative to the container main body in the axial direction.

In the toner container provided by the above solution, after the connecting piece is locked by the electrostatic imaging device, when the electrostatic imaging device moves the container body away from the connecting piece, the pressing mechanism forces the connecting piece to protrude relative to the container main body in the axial direction, that is, pressing The mechanism applies force to the container body in the moving direction, which reduces the driving force of the electrostatic imaging device to move the container body, that is, reduces the user's force when installing the toner container, and facilitates the operation. In addition, the mechanism for moving the container main body of the electrostatic imaging device is not easily damaged due to the reduced force.

After the connecting member is disengaged from the driving part of the electrostatic image forming apparatus, the toner container is taken out directly in the direction indicated by arrow B in FIG. 3B.

Embodiment two

If Embodiment 1 is used for the electrostatic imaging device where the toner container is installed horizontally (that is, the toner container is installed along the direction perpendicular to its axis), since the pressing member 5 always forces the connecting member 2 to protrude, the total length of the toner container It is longer than the length of the accommodating tank for placing the toner container on the electrostatic imaging device. In the process of placing the toner container in the accommodating tank, the toner container needs to be tilted, and the pressing member needs to be forced 5 Compression to shorten the overall length of the toner container, which is inconvenient for installation.

In order to solve the above shortcomings of the first embodiment, the second embodiment is proposed.

Referring to Fig. 8, the structures of the toner container body, connecting member 2 and shutter member 3 of this embodiment are the same as those of the first embodiment, wherein the same structures are denoted by the same reference numerals in this embodiment. The difference between this embodiment and the first embodiment lies in the specific structural forms of the guide piece 4' and the pressing mechanism.

The pressing mechanism in this embodiment includes an outer sleeve 51 , an inner sleeve 52 , a rotating sleeve 53 , a spring 54 and a cap 55 . The outer sleeve 51 is integrally formed with the stirring blade 14a, or may be separately formed with the stirring blade 14a and then fixed together. The front end of the outer sleeve 51 is open, and the rear end is snap-connected with the cap 55 . Referring to Fig. 10, the inner diameter of the front end of the outer sleeve 51 is smaller than the inner diameter of the rear end, and the inner wall of the middle part connecting the front end and the rear end of the outer sleeve 51 is provided with deep grooves 511 and shallow grooves 512 symmetrically arranged in the circumferential direction, deep grooves 511 and shallow grooves 512 equal width and spaced apart from each other. The groove bottom of the deep groove 511 is on the same cylindrical surface as the rear end inner wall of the inner casing 51 , and the groove bottom of the shallow groove 512 is radially inward of the groove bottom of the deep groove 511 .

Referring to Fig. 11, the outer diameter of the inner sleeve 52 is slightly smaller than the inner diameter of the front end of the outer sleeve 51, and the outer wall surface of the rear end is provided with a ring of protrusions 521 symmetrically arranged in the circumferential direction, and the width of the protrusions 521 is slightly smaller than the shallow groove 512 and the width of the deep groove 511, its top surface is on a cylindrical surface coaxial with the outer wall of the inner casing 52, and the radius of the cylindrical surface is less than the distance from the axis of the outer casing 51 to the bottom of the shallow groove 512, but greater than that of the outer casing 51 Front inner radius. The rear end surface of the protrusion 521 is an inclined plane 522a and 522b, and the tops of the two inclined planes intersect on the circumferential center plane of the protrusion. As shown in Figures 8 and 9, when the inner sleeve 52 is assembled with the outer sleeve 51, the inner sleeve 52 is inside the outer sleeve 51, and the front end of the inner sleeve 52 always extends out of the front end of the outer sleeve 51. The protrusion 521 of 52 is in the deep groove 511 and the shallow groove 512 of the outer sleeve 51, and forms a clearance fit with the deep groove 511 and the shallow groove 512. Relative to the outer sleeve 51 , the inner sleeve 52 can slide in the axial direction, but cannot rotate in the circumferential direction.

Referring to Fig. 8 and Fig. 12, the rotating sleeve 53 is arranged in the outer sleeve 51, and its front end is a cylinder which forms a clearance fit with the inner wall of the inner sleeve 52, and a circle of symmetrically arranged rings is arranged on the outer wall of the rear end. The protrusion 531 , the distance from the axis of the rotating sleeve 53 to the top surface of the protrusion 531 is slightly smaller than the inner radius of the rear end of the outer sleeve 51 . The front end surface of the protrusion 531 is a slope 532 inclined to one side, the slope 532 is in the same direction as the slope 522b of the inner sleeve 52, and the slope 532 is less than or equal to the slope of the slope 522b, so that the top of the slope 522b can Sliding within the ramp 532 . The spring 54 is placed between the rotating sleeve 53 and the cap 55, and its two ends press on the rotating sleeve 53 and the cap 55 respectively.

Referring to Fig. 8, the structure of the guide 4' in this embodiment is different from that of the guide 4 in Embodiment 1 in that the guide 4' removes the slot 43 in the guide 4, and a rear end is designed The cylinder of the inner sleeve 52 can be inserted.

Fig. 8 is a partial cross-sectional view of the toner container of this embodiment, wherein the pressing mechanism is in a compressed and locked state; Fig. 9 is an enlarged cross-sectional view of the pressing mechanism in Fig. 8 along the D-D direction; Fig. 12 is a pressing mechanism in the Perspective view of inner sleeve and swivel sleeve mating in compression-locked state. The working process of the pressing mechanism will be described below with reference to FIG. 8 , FIG. 9 and FIG. 12 .

The urging mechanism in Fig. 8 is in the compressed locking state, the compression here refers to that the spring 54 has a relatively large compression amount, and the total length of the toner container is relatively short, and the locking refers to that if the urging mechanism is not subjected to a large enough External forces will maintain this state. At this time, the top of the inclined surface 522b of the protrusion 521 on the inner sleeve 52 is on the side close to the top of the inclined surface 532, and is in contact with the inclined surface 532, as shown in FIG. 12 . Referring to FIG. 8 and FIG. 12 , when the inner sleeve 52 receives a force along the arrow C direction and greater than the force of the spring 54 , the inner sleeve 52 pushes the rotating sleeve 53 to move along the arrow C direction. During this process, because the rotating sleeve 53 is simultaneously affected by the inner sleeve 52 and the spring 54, the top of the inclined surface 522b on the inner sleeve 52 slides in the inclined surface 532 of the rotating sleeve 53, and the rotating sleeve 53 is opposite to the inner sleeve. The tube 52 rotates in the direction of arrow E in FIG. 12 until the top of the slope 522 b slides to the bottom edge of the slope 532 . At this point, the top edge of the slope 532 has slid into the deep groove 511 . In this state, cancel the pushing of the inner sleeve 52 in the direction of the arrow C, and under the restoring force of the spring 54 , the slope 532 of the rotating sleeve 53 will slide into the deep groove 511 along the edge of the deep groove 511 . When the protrusion 531 on the rotating sleeve 53 slides into the deep groove 511 completely, the top of the inclined surface 522b contacts the middle or near the middle of the inclined surface 532, and the spring 54 pushes the rotating sleeve 53 and the inner sleeve 52 to the opposite direction of the arrow C in FIG. 8 Move until the front end of the protrusion 521 on the inner sleeve 52 is blocked by the front ends of the deep groove 511 and the shallow groove 512. At this time, the front end of the inner sleeve 52 extends the longest distance from the front end of the outer sleeve 51, and the total length of the toner container reaches At longest, the pressing mechanism is in the extended locked state. The extension here means that the compression amount of the spring 54 is relatively small, and the total length of the toner container is relatively long, and the locking means that the pressing mechanism will maintain this state if it is not subjected to a large enough external force. In this state, the top of the slope 522b is in contact with the middle or near the middle of the slope 532 . To sum up, when the pressing mechanism is in the compression locking state, apply a large enough force to the inner sleeve 52 in the direction of the arrow C, and then cancel the force, the pressing mechanism will move from the compression locking state to the extension locking state.

When the pressing mechanism is in the extended locking state, push the inner sleeve 52 in the direction of arrow C in FIG. The spring 531 is completely slid out of the deep groove 511 of the outer sleeve 51, and the spring 54 is further compressed. During this process, since the protrusion 531 on the rotating sleeve 53 has been limited in the deep groove 511 of the outer sleeve 51, the rotating sleeve 53 only slides axially and cannot rotate circumferentially. When the rotating sleeve 53 completely slides out of the deep groove 511 of the outer sleeve 51, since the rotating sleeve 53 is pushed by the inner sleeve 52 and the spring 54 at the same time, the inner sleeve 52 moves axially while its The top of the inclined surface 522 b slides in the inclined surface 532 of the rotating sleeve 53 , and the rotating sleeve 53 rotates clockwise until the top of the inclined surface 522 b slides to the bottom edge of the inclined surface 532 . In this state, cancel the pushing of the inner sleeve 52 in the direction of arrow C, and the restoring elastic force of the spring 54 will push the rotating sleeve 53 and the inner sleeve 52 to slide in the opposite direction of arrow C. During this process, the rotating sleeve The tube 53 only slides axially until the edge of the shallow groove end surface 513 (see FIG. 10 ) of the outer sleeve 51 connected to the deep groove 511 touches the slope 532 of the rotating sleeve 53 . , the rotating sleeve 53 rotates clockwise while continuing to slide in the opposite direction of the arrow C until the rotating sleeve 53 returns to the connection state with the inner sleeve 52 as shown in FIG. 12 . At this time, since the inclined surface 532 of the rotating sleeve 53 is blocked by the end surface 513 of the shallow groove 512 and stops axial sliding, the pressing mechanism returns to the compressed locking state shown in 8 . To sum up, when the pressing mechanism is in the extension locking state, apply a large enough force to the inner sleeve 52 in the direction of arrow C, and then cancel the force, the pressing mechanism will move from the extension locking state to the compression locking state.

The loading and unloading and working process of the toner container in this embodiment will be described below in conjunction with the pressing mechanism.

When the toner container has not been installed on the electrostatic imaging device, the pressing mechanism is in the locked and contracted state as shown in Figure 8, the total length of the toner container is relatively short, and the toner container is installed on the electrostatic imaging device , the toner container can be put into the accommodating groove of the electrostatic imaging device in parallel along the direction perpendicular to its axis. Then, the electrostatic image forming device pushes the toner container in the opposite direction of the arrow C in FIG. Pushing to open the powder outlet, the inner sleeve 52 is pushed by the guide 4' along the arrow C direction. After the driving part 81 locks the connector 2, the electrostatic imaging device moves the container body 1 in the direction of the arrow C in FIG. Move to the extended locking state, the total length of the toner container increases, the main body of the container retreats to a predetermined position, and the toner container can start to work. The process of the pressing mechanism moving from the compressed locked state to the extended locked state has been described in detail above and will not be repeated here.

The process of supplying toner from the toner supply container to the electrostatic imaging device and resealing the toner outlet in this embodiment is the same as that in the embodiment, and will not be repeated here. After the connecting piece is detached from the driving part of the electrostatic imaging device, the toner supply container is directly taken out from the accommodating groove of the electrostatic imaging device along the direction perpendicular to its axis. The toner supply container is taken out from the electrostatic image forming apparatus, and its pressing mechanism is in an extended locked state. If the toner supply container needs to be installed on the electrostatic imaging device again, first move the pressing mechanism of the toner supply container to the compression lock state, shorten the total length of the toner container, and then put the toner container along the vertical axis Orientation into the receiving slot of the electrostatic imaging device. The process of the pressing mechanism moving from the extended locked state to the compressed locked state has been described in detail above, and will not be repeated here.
