Description

Technical Field

[0001] The present invention relates to the technical field of copiers, and more particularly to a toner container and a copier equipped with the container. Background Art

[0002] For a copy machine, and an image forming apparatus such as a printer, a fax machine, or a multifunction peripheral (MFPs) similar to a copy machine, there is a toner container (developer container) detachably mounted in an apparatus body of the image forming apparatus. The toner container is bottle-shaped, and when the toner container is mounted in the apparatus, a nozzle of the apparatus body is inserted into an opening of the toner container to discharge the toner (developer) contained in the toner container.

[0003] For example, the toner container mentioned in the toner storage container and image forming device with application number CN201410312467.X applied by Ricoh Co., Ltd. of Japan, and the nozzle receiving device, powder container and image forming device with application number CN201580001041.5. Specifically, in the toner container of the above patent document, a shutter for opening and closing the opening is included, the shutter is formed in one body with a guide rod, and a nozzle is inserted in the container. The guide rod is movably supported in the toner container along the opening and closing direction (axial direction) by the valve bracket. When the toner container is installed in the device, at the same time as the toner container is installed in the device, the shutter is pushed by the nozzle and moves to the position of the opening together with the guide rod. Then, when the container body of the toner container rotatable relative to the shutter bracket rotates, the toner (developer) contained in the toner container is discharged to the outside of the toner container via the nozzle inserted in the opening.

[0004] It should be noted that in the toner container (developer container) of the above patent document, the bracket (gate support) for supporting the guide rod covers half of the entire circumference of the guide rod and the compression spring (or nozzle). As a result, the toner (developer) is agglomerated between the bracket, the guide rod and the compression spring (or nozzle). Therefore, there may be a problem that the gate and the guide rod (or nozzle) cannot move smoothly in the opening and closing direction, resulting in the gate being unable to open and close, or the toner (developer) contained in the toner box cannot be satisfactorily discharged through the nozzle.

[0005] Based on this, a Chinese invention patent with application number CN201880032915.7 discloses a developer container and an image forming device including the same, which changes the original bracket structure for supporting the guide rod so that the circumferential area around the guide rod and the compression spring facing the bridging part is smaller than the circumferential area around the guide rod and the compression spring not facing the bridging part, so that the gate plate and the guide rod (or nozzle) can move smoothly in the opening and closing directions, or the colorant (developer) contained in the colorant container can be satisfactorily discharged through the nozzle.

[0006] The problem that is not solved in the above patent document is that there is a gap between the bracket and the inserted nozzle, and the gap is at the receiving end where the toner is transported in the container body. At the same time, the nozzle shield covers one end of the gap (opening) in a limited manner, and the toner will enter the gap in a directional manner and agglomerate between the bracket and the nozzle without being able to be discharged. Therefore, the problem that may arise is that the nozzle cannot move smoothly in the direction of insertion and extraction in the container body, resulting in the nozzle being unable to be smoothly separated and disassembled from the container body, and forced disassembly is also likely to cause damage to the nozzle. Moreover, in the developer container and the image forming device including it, due to the change in the bracket structure supporting the guide rod, the bridging part cannot block the gap over a large area, reducing the difficulty of the toner entering the gap, making the agglomeration problem more likely to occur. Summary of the invention

[0007] The purpose of the present invention is to provide a colorant container to address the deficiencies of the prior art, so as to increase the difficulty of colorant agglomeration in the gap, extend the required time for agglomeration, and enable the nozzle to move smoothly in the container body along the insertion and extraction directions; and based on the colorant container, provide a copier equipped with the container.

[0008] The technical solutions of the present invention are as follows: A toner container, comprising: a container body for accommodating toner; a bracket supporting and connecting the container body, the bracket comprising a fitting portion having an opening; a shutter for opening and closing the opening of the toner container, the opening being used for inserting the nozzle of the apparatus body; and further comprising: A blocking member is installed in the fitting portion at a distance from the opening to position the shield connected to the nozzle and prevent the shield from covering the opening; and a portion communicating with the opening is present in the interval between the opening and the blocking member, and a collecting chamber is formed in the portion, and the toner in the opening is pushed into the collecting chamber by the toner in the container body; The blocking member has an insertion opening which is arranged opposite to the opening and is used for inserting the nozzle.

[0009] In the above scheme, the ports on both sides of the opening are always in an open state. As the colorant in the container body is pushed, the colorant that enters the opening later will push the colorant that enters the opening earlier to move toward the collection chamber, so as to avoid the colorant from agglomerating and piling up in the opening to form lumps, or more precisely, to form lumps in the gap left after the nozzle is inserted into the opening, so that the nozzle can move smoothly in the container body along the direction of insertion and extraction.

[0010] As a preferred solution, it also includes: a guide rod formed integrally with the shutter, the guide rod extending in the container body along the opening and closing direction of the shutter; The support also includes: a supporting portion disposed opposite to the gate, the supporting portion comprising at least two parts to movably support the guide rod in the opening and closing directions; A bridging portion, used to connect the supporting portion and the engaging portion inside the container body; A compression spring is wound on the guide rod, and the compression spring is located between the support portion and the gate plate to push the gate plate in a direction of closing the opening; A circumferential area around the guide rod and the compression spring facing the bridge portion is smaller than a circumferential area around the guide rod and the compression spring not facing the bridge portion.

[0011] As a preferred solution, the barrier is an independent component, which is detachably connected to the engaging portion.

[0012] As a preferred solution, a sealing member is installed in the embedding portion, a through hole is provided on the sealing member, and the through hole is a component of the opening, and the blocking member is connected to the sealing member and formed as a whole.

[0013] As a preferred solution, the aperture of the opening is matched to the outer diameter of the nozzle, and the aperture of the socket is larger than the aperture of the opening.

[0014] As a preferred solution, there is a step portion between the opening and the bridge portion, so that a step structure is formed between the inner wall of the opening and the bridge portion, thereby preventing the toner falling on the bridge portion from directly flowing into the opening.

[0015] As a preferred solution, the end surface of the bridge portion facing the guide rod includes two inclined surfaces arranged at an angle, and the inclined surfaces guide the toner to fall from the bridge portion to both sides.

[0016] As a preferred solution, the bridge portion includes a guide rail for slidably supporting the gate plate, and a plurality of discharge ports are provided on the guide rail at intervals to guide the toner accumulated on the bridge portion out of the bridge portion from the discharge ports through the inclined surface.

[0017] As a preferred solution, the gate plate is provided with a positioning groove adapted to the nozzle insertion end to insert the insertion end and provide positioning support.

[0018] A copying machine is equipped with the above-mentioned toner container.

[0019] The main beneficial effects of the present invention are: 1. There is no cover on both ends of the opening, and the toner can flow in from one end of the gap and out from the other end. It is not easy to be pressed into the gap due to the force to form a mass, thereby avoiding hindering the nozzle from moving smoothly in the direction of insertion and extraction in the container body.

[0020] 2. A collection chamber is formed to collect the toner flowing out of the gap in a targeted manner to prevent this part of the toner from interfering with the movement of the nozzle.

[0021] 3. You can choose a suitable barrier structure or sealing structure according to your needs.

[0022] 4. The opening is adapted to the outer diameter of the nozzle to reduce the amount of toner entering the gap, reduce the possibility of agglomeration and the impact of agglomeration; the socket is larger than the opening diameter so that the toner flowing out of the gap can be collected in a targeted manner in the socket to increase the overall toner collection space.

[0023] 5. A step structure is formed between the inner wall of the opening and the bridge portion to prevent the toner falling on the bridge portion from flowing directly into the opening, thereby increasing the difficulty of the toner entering the gap, thereby reducing the amount of toner entering the gap and reducing the possibility of agglomeration.

[0024] 6. An inclined surface is provided to guide the toner to fall from the bridge portion to both sides to prevent the toner from accumulating on the bridge portion. This can prevent the toner accumulated on the bridge portion from flowing into the gap on the one hand, and prevent the toner from agglomerating between the bridge portion and the nozzle, and between the bridge portion and the gate plate on the other hand.

[0025] 7. Add guide rails to provide sliding support for the gate so that the gate can slide more smoothly. At the same time, a discharge port needs to be set on the guide rail to prevent the toner from accumulating on the bridge part.

[0026] 8. Connect the gate plate to the nozzle by plugging it into the container body. After the nozzle is inserted into the container body, the gate plate can position and support the nozzle to ensure that the nozzle can smoothly transport the toner, thereby reducing the effect of the increase in nozzle length caused by the addition of a barrier and reducing the stability of the nozzle insertion end.

[0027] Further or more detailed beneficial effects will be described in detail in conjunction with specific examples in the specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following description is only a preferred embodiment of the present invention and does not limit the scope of the present invention. In addition, the terms "vertical", "horizontal", "front", "rear" and the like mentioned in the embodiments of the present invention indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the product is usually placed when in use, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be further explained that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like in the description should be understood in a broad sense, for example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0041] It is explained in advance that the installation position and function of the colorant container in the device body (i.e., the copier) are the same as those of the existing commonly used colorant containers without modification. Those skilled in the art can understand it in conjunction with the developer container in the Chinese invention patent with application number CN201880032915.7 and the image forming device including it.

[0042] For details, please refer to the attached Figure 1 To Attachment Figure 4 , the toner container in the present invention accommodates toner as a powdery developer in an apparatus main body (ie, a copying machine) and is removable from the apparatus main body (ie, a copying machine).

[0043] Reference Figure 2 The toner container includes a container body 1, a bracket 2, a shutter 3, a guide rod 301, a compression spring 7, etc. The bracket 2 supports and connects the container body 1, and the container body 1 rotatable relative to the bracket 2 in the present invention is bottle-shaped and has a spiral protrusion formed on its inner circumference. The spiral protrusion is arranged on an inner circumference of the container body 1. Specifically, the spiral protrusion protrudes inward from its outer circumference to the inner circumference, and is used to rotate the container body 1 from the inner circumference to the outer circumference. Figure 1 The toner is transported from the left side of the container body 1 to the right side. Figure 1 The toner conveyed from the left side to the right side in the toner container is discharged to the outside of the toner container through the nozzle 4.

[0044] According to the existing assembly method, when the toner container is installed in the device body (i.e., the copier), the bracket 2 (and the shutter 3, the guide rod 301 and the compression spring 7) are fixed to the device body (i.e., the copier) without rotation. The drive motor installed in the device body (i.e., the copier) rotates the container body 1, thereby discharging the toner contained in the toner container through the nozzle 4.

[0045] The nozzle 4 is provided with a conveying screw commonly used for conveying powder. The conveying screw is connected to the motor. When the motor rotates the conveying screw, the toner flowing into the nozzle 4 from the feed port 402 deep in the toner container is conveyed by the conveying screw. Figure 1 The toner is transported from the left side to the right side, and then discharged into the external structure through the outlet of the nozzle 4, such as the developer container in the Chinese invention patent with application number CN201880032915.7 and the hopper in the image forming device including it.

[0046] The gate 3 is used to open the opening 2011 (see attached Figure 2 ) and closed opening 2011 (refer to Attachment Figure 3 ), the opening 2011 is an insertion port for the nozzle 4 (installed in the device body (i.e., the copier)) when the toner container is installed in the device body (i.e., the copier). The shutter 3 is made of a resin material and is molded as a whole with a guide rod 301 to be described later. The shutter 3 is assembled into the opening 2011 from the inside of the toner container and is locked so as not to be removed from the container body 1. When the shutter 3 closes the opening 2011, no toner is discharged from the toner container, and when the shutter 3 opens the opening 2011, toner can be discharged from the toner container. The specific installation structure of the shutter 3 will be described in detail later in conjunction with the structure of the bracket 2.

[0047] The opening 2011 is a roughly cylindrical hole centered at the rotation center of the container body 1. The shutter 3 is shaped so as to fit into the cylindrical opening 2011. The aperture of the opening 2011 is larger than the outer diameter of the nozzle 4, so that the nozzle 4 can be smoothly inserted into the container body 1 without wear to transport the toner. Therefore, there is inevitably a gap between the nozzle 4 and the inner wall of the opening 2011 where the toner can gather. Since the transport efficiency of the nozzle 4 is constant, when the container body 1 rotates from the opening 2011, the toner can be transported to the container body 1. Figure 4 When the toner is transported from the left side to the right side of the container body 1, part of the toner will enter the opening 2011 along with the transport impact, more specifically, enter the gap left after the nozzle 4 is inserted into the opening 2011.

[0048] Therefore, in order to prevent the toner in the gap from being impacted and pushed by the toner entering the gap later and agglomerated, the present invention sets a barrier 5 in the bracket 2. Figure 1 One side thereof is spaced apart from the opening 2011, and the other side thereof supports the baffle 401 contacting the nozzle 4 to form a barrier structure between the opening 2011 and the baffle 401, so as to prevent the baffle 401 from directly covering the opening 2011 or covering the gap, so as to keep the two ends of the opening 2011 or the two ends of the gap in an uncovered opening state, so that the colorant that enters first and exists in the gap will flow out from the gap toward the opening at the end of the baffle 401 under the impact and push of the colorant that enters the gap later, so as to avoid being squeezed and agglomerated in the gap.

[0049] Specifically, refer to Figure 1 (as well as Figures 4 to 6 ), the bracket 2 includes a supporting portion 202, a fitting portion 201, a bridging portion 203, etc., and when the bracket 2 is installed in the device body (ie, the copier), the bracket 2 is fixed to be non-rotatable.

[0050] The engaging portion 201 (cover portion) of the bracket 2 has an opening 2011, and the container body 1 is rotatably assembled on the engaging portion 201; and the container body 1 is attached to the engaging portion 201 through a sealing structure so that the toner does not leak out from the gap between the engaging portion 201 and the container body 33. The above-mentioned sealing structure is a commonly used mounting structure between the existing container body 1 and the bracket 2. The engaging portion 201 also includes an engaging portion for engaging with an engaged portion formed in the toner container to fix the engaging portion 201 along the circumference of the container body 1 and the toner container. As a result, when the toner container is installed in the device body (i.e., the copier), the bracket 2 is positioned in a state where the bridge portion 203 to be described later is located below the guide rod 301.

[0051] A blocking member 5 is installed in the interlocking portion 201 at a distance from the opening 2011 to position the shield 401 connected to the nozzle 4 and block the covering opening 2011; the blocking member 5 has a socket 501 arranged opposite to the opening 2011 and used to insert the nozzle 4, and the nozzle 4 is inserted through the socket 501 and the opening 2011 in sequence to enter the container body 1.

[0052] Reference Figure 4 To Attachment Figure 5 The barrier 5 may be an independent component, which is detachably mounted in the fitting portion 201 with reference to the sealing member 8 mounted in the fitting portion 201, or detachably mounted in the fitting portion 201 by twisting with a common thread structure.

[0053] Reference Figure 6The barrier 5 may also be a part of the sealing member 8 in the fitting part 201. The sealing member 8 is installed in the fitting part 201, and the sealing member 8 is provided with a through hole, and the through hole is a component of the opening 2011. The barrier 5 is connected with the sealing member 8 and formed as a whole.

[0054] When the blocking member 5 is installed in the fitting portion 201, there is a portion in communication with the opening 2011 in the interval between the opening 2011 and the blocking member 5, and the portion forms a collecting chamber 6, and the collecting chamber 6 forms a directional collecting structure for the toner flowing out of the gap. Specifically, the toner first stored in the gap will flow out from the end opening of the gap toward the shielding plate 401 to the collecting chamber 6 under the impact and pushing action of the toner entering the gap later. The toner entering the collecting chamber 6 will not form a limit on the toner in the gap until it is filled to cover the opening of one end of the gap, that is, the end opening of the gap toward the shielding plate 401, so that the toner cannot be discharged from the gap, and will be gathered and pressed and agglomerated in the gap under the impact and pushing action of the toner entering the gap later. Therefore, by increasing the space size of the collection chamber 6 according to demand, the amount of colorant collected and contained can be adjusted to extend the agglomeration time of the colorant in the gap. When the required time is longer than the use time of the colorant container, agglomeration will not or is unlikely to occur.

[0055] Specifically, the aperture of the opening 2011 in the present invention is adapted to the outer diameter of the nozzle 4, that is, under the assembly condition that the nozzle 4 can be smoothly inserted into the opening 2011, the outer diameter of the nozzle 4 should be as close to the aperture of the opening 2011 as possible, so as to reduce the gap between the opening 2011 and the nozzle 4, so as to reduce the amount of toner entering the gap and reduce the possibility of agglomeration. At the same time, the aperture of the socket 501 is larger than the aperture of the opening 2011, so that the socket 501 can also collect the toner flowing out of the gap in a directional manner, so as to increase the overall toner collection space, so as to prolong the time for the toner in the collection chamber 6 to fill up to cover the opening at one end of the gap, thereby prolonging the time for agglomeration to occur in the gap and reducing the possibility of agglomeration.

[0056] The guide rod 301 of the present invention is integrally provided with the shutter 3. The guide rod 301 is arranged in the toner container along the opening and closing direction of the shutter 3 (in Figure 1 to Figure 2 The transverse direction of the Figures 4 to 6 As shown, the guide rod 301 is arranged so that its axis line substantially coincides with the rotation center of the container body 1 .

[0057] The support portion 202 of the bracket 2 is located on the opposite side to the shutter 3 installed inside the toner container ( Figure 2 and 3 On the left side, Figure 4 and 6The support portion 202 includes at least two parts to movably support the guide rod 301 in the direction of opening and closing the opening 2011 of the gate 3, wherein the two parts refer to the presence of two structures on the support portion 202 for movably supporting the guide rod 301.

[0058] More specifically, the support portion 202 is a U-shaped frame, such as the U-shaped frame in the developer container of application number N201880032915.7, which is provided with two holes, which are separated from each other in the direction of movement of the shutter 3. When the U-shaped frame is combined with the bridge portion 203 described later, the guide rod 301 is sequentially inserted through the two holes on the U-shaped frame to be positioned and installed on the support portion 202, and the guide rod 301 is supported by the support portion 202 in the direction of the rotation axis of the container body 1.

[0059] The bridge portion 203 of the bracket 2 connects the support portion 202 and the fitting portion 201 inside the toner container (container body 1). Here, in the present embodiment, the bridge portion 203 does not cover the periphery of the guide rod 36 (and the compression spring 7) in a large range, but covers the periphery of the guide rod 301 (and the compression spring 7) in a narrow range.

[0060] Reference Figure 8 There is a step portion 204 between the opening 2011 and the bridge portion 203, so that a step structure is formed between the inner wall of the opening 2011 and the bridge portion 203, which prevents the toner falling on the bridge portion 203 from directly flowing into the opening 2011 laterally. At the same time, the end surface of the bridge portion 203 facing the guide rod 301 includes two inclined surfaces 2031 arranged at an angle. Such a structure enhances the strength of the bridge portion 203, and at the same time enables the inclined surfaces 2031 to guide the toner to fall from the bridge portion 203 to both sides, thereby preventing the toner from accumulating on the bridge portion 203. In this way, on the one hand, the toner accumulated on the bridge portion 203 can be prevented from flowing into the gap, and on the other hand, the toner agglomeration between the bridge portion 203 and the nozzle 4, and between the bridge portion 203 and the gate plate 3 can be prevented.

[0061] Reference Fig. 9 The bridge portion 203 includes a guide rail 2032 that is in sliding contact with the gate plate 3 moving in the opening and closing direction. Specifically, the guide rail 2032 is vertically arranged on the inclined surface 2031, and the two spaced guide rails 2032 together constitute a sliding support structure of the gate plate 3. Through such a structure, the gate plate 3 and the guide rail 2032 are in line contact, so that the gate plate 3 moves smoothly with a small sliding resistance. At the same time, a plurality of discharge ports 2033 are spaced apart on the guide rail 2032, one side of the discharge port 2033 faces the space formed between the two spaced guide rails 2032, and the other side faces the outside, so as to guide the toner accumulated on the bridge portion 203 out of the bridge portion 203 through the inclined surface 2031 from the discharge port 2033.

[0062] Reference Figures 4 to 6 The compression spring 7 (energizing member) is between the gate plate 3 and the support portion 202 and is wound around the guide rod 301. The compression spring 7 is compressed in the direction of closing the opening 2011 (in Figure 2 and 3 to the right, in Figures 4 to 6 Push gate plate 3 (to the left).

[0063] With such a configuration, as the toner container is mounted, the nozzle 4 pushes the shutter 3 , and the shutter 3 overcomes the urging force of the compression spring 7 and moves to the inside of the toner container, thereby opening the opening 2011 .

[0064] On the other hand, accompanying the removal of the toner container from the device body (i.e., the copier), the nozzle 4 releases the shutter 3 from the push, and the shutter 3 moves toward the opening 2011 under the action of the force of the compression spring 7, thereby closing the opening 2011. When the operation of installing the toner container in the device body (i.e., the copier) is completed, the shutter 3 contacts the support portion 202, and the compression spring 7 is accommodated in the recess of the shutter 3. Therefore, when the toner container is placed in the device body (i.e., the copier), the toner in the container can be prevented from adhering to the compression spring 7.

[0065] In the toner container of this embodiment, the range where the bridge portion 203 faces the guide rod 301 and the compression spring 7 is smaller than the range where the bridge portion 203 does not face the guide rod 301 and the compression spring 7. Therefore, the bridge portion 203 has limited support for the gate plate 3. At the same time, due to the addition of the barrier 5, the size of the nozzle 4 needs to be increased to allow the nozzle 4 to push the gate plate 3 to connect with the support portion 202. Therefore, the installation stability of the nozzle 4 when inserted into the container body 1 is greatly reduced, which may result in the nozzle 4 swinging or even deflecting, causing the conveying screw inside the nozzle 4 for conveying the toner to be stuck with the nozzle 4, resulting in the conveying screw being unable to run smoothly, and the toner cannot be conveyed stably.

[0066] Reference Fig.11 , the gate plate 3 is provided with a positioning groove 302 with a notch facing the nozzle 4, and the notch profile of the positioning groove 302 is determined according to the structure of the end of the nozzle 4 inserted into the container body 1, so that the nozzle 4 is inserted into the positioning groove 302 in an adaptive manner, and then the gate plate 3 is pushed to connect with the support part 202. At this time, the gate plate 3 is stably attached to the support part 202, and can provide stable positioning support for the insertion end of the nozzle 4, so as to reduce the influence of the increase in the length of the nozzle 4 due to the addition of the barrier 5, which reduces the stability of the insertion end of the nozzle 4, so as to avoid the nozzle 4 from swinging or even deflecting, so as to ensure that the nozzle 4 can stably transport the toner in the container body 1.

[0067] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
