[0002] Image forming equipment, such as laser color printers, copiers, and multifunction printers, all have internal cleaners that transfer excess toner to waste toner cartridges.

[0003] However, when the image forming equipment is operated in a long-term or intermittent manner, the toner is prone to clumping on the inner wall of the toner collection chamber and at the toner inlet due to the rise in temperature, resulting in dirty images, abnormal noise from the equipment, etc. Summary of the Invention

[0004] This application provides a toner conveying mechanism and an image forming device, which aims to reduce the risk of toner agglomeration.

[0005] This application embodiment provides a toner conveying mechanism, the toner conveying mechanism comprising:

[0006] A toner collection chamber having a receiving cavity;

[0007] A rotating component is disposed in the receiving cavity and is rotatable relative to the toner collection chamber;

[0008] The cleaning component, when viewed along the axis of the rotating member, is at least partially located between the receiving cavity and the rotating member, and the cleaning component can be pushed to reciprocate along the axial direction of the rotating member.

[0009] In one possible design, the toner collection chamber also has a hopper opening that communicates with the receiving cavity;

[0010] The cleaning component is provided with a protrusion, which is located at the opening of the compartment.

[0011] In one possible design, the toner conveying mechanism further includes a cleaning scraper, which is mounted on the outside of the compartment opening and is capable of conveying toner through the compartment opening into the receiving cavity;

[0012] The cleaning scraper is positioned close to the protrusion, and the cleaning scraper can restrict the cleaning component from rotating with the rotating member.

[0013] In one possible design, as the cleaning component reciprocates along the axial direction of the rotating member, the outer peripheral wall of the cleaning component comes into frictional contact with the inner wall of the toner collection chamber.

[0014] In one possible design, the outer wall of the rotating component is provided with a guide rail, and the cleaning component is provided with a sliding part that slides with the guide rail;

[0015] When the rotating component rotates, the inner wall of the guide rail can guide the sliding part to move along the guide rail, thereby pushing the cleaning component to reciprocate along the axial direction of the rotating component.

[0016] In one possible design, the guide rail is spiral-shaped.

[0017] In one possible design, the rotating component includes a support portion;

[0018] The cleaning component is fitted around the outer ring of the support and can reciprocate along the axial direction of the support.

[0019] In one possible design, the rotating member further includes a driven part connected to the support part;

[0028] Equipment body;

[0029] A toner conveying mechanism is installed on the equipment body, and the toner conveying mechanism is the toner conveying mechanism described above.

[0030] The beneficial effects of this embodiment are as follows: When the image forming apparatus starts operating, the rotating component can rotate relative to the toner collection chamber, and at the same time, the cleaning component can be pushed to reciprocate along the axis of the rotating component (similar to piston movement). During the reciprocating motion of the cleaning component within the receiving cavity, the cleaning component can pulverize the toner that may be clumped or is about to clump within the receiving cavity, so that the rotating component can evenly deliver the toner to the toner bottle. This cycle ensures that the toner collection chamber can continuously collect toner, thereby guaranteeing the normal operation of the image forming apparatus.

[0031] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0061] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0062] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0065] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0066] This application provides an image forming apparatus, please refer to the following for details. Figure 1 , Figure 1 This is a schematic diagram of an image forming apparatus 1, which can be a multi-functional image forming apparatus 1 with functions such as printing, copying, scanning, and faxing. The image forming apparatus 1 includes an apparatus body 11, an intermediate printing module 12, and a toner delivery mechanism 13, which are mounted on the apparatus body 11.

[0067] In one embodiment, the toner conveying mechanism 13 can be a waste toner transport mechanism. The toner conveying mechanism 13 is located near the intermediate printing module 12 and is used to clean excess toner from the transfer belt 121 of the intermediate printing module 12, allowing the transfer belt 121 to continue with the next transfer and ensuring the normal operation of the intermediate printing module 12. The cleaned toner can also be conveyed to a toner bottle via the toner conveying mechanism 13 for recycling.

[0068] In other embodiments, the toner conveying mechanism 13 may also be located at other positions on the equipment body 11 to clean, convey, or clean waste toner or toner from other modules on the equipment body 11, such as the photosensitive drum. The specific configuration can be determined according to actual conditions, and this embodiment does not impose any limitations.

[0069] The specific structure of the toner conveying mechanism will be described in detail below with reference to the accompanying drawings.

[0070] Figure 2 This is a schematic diagram of the toner conveying mechanism 13. Figure 3 This is a cross-sectional schematic diagram of the toner conveying mechanism 13. Please refer to the reference. Figure 2 and Figure 3 The toner conveying mechanism 13 includes a toner collection chamber 131, which has a receiving cavity 131a and a chamber opening 131b. The chamber opening 131b is connected to the receiving cavity 131a, and both the chamber opening 131b and the receiving cavity 131a are used to receive collected toner. The toner conveying mechanism 13 also includes a cleaning scraper 134, which is installed on the outside of the toner collection chamber 131 and located outside the chamber opening 131b. The cleaning scraper 134 can convey toner through the chamber opening 131b into the receiving cavity 131a.

[0071] Specifically, the cleaning scraper 134 is inclinedly positioned above the transfer belt 121 of the intermediate printing module 12, with one side of the cleaning scraper 134 fixedly connected to the toner collection chamber 131, and the other side of the cleaning scraper 134 positioned close to the transfer belt 121. Along the moving direction of the transfer belt 121, the cleaning scraper 134 is positioned behind the chamber opening 131b. As the transfer belt 121 moves, when the toner on the transfer belt 121 passes the cleaning scraper 134, the cleaning scraper 134 can prevent the toner from continuing to move with the transfer belt 121, allowing the toner on the transfer belt 121 to enter the receiving cavity 131a from the chamber opening 131b in front of the cleaning scraper 134, thereby achieving toner collection.

[0072] In some embodiments, the toner delivery mechanism 13 can also deliver toner from the receiving cavity 131a to a toner bottle for recycling.

[0073] When the image forming equipment 1 operates for a long time, the toner is prone to clumping on the inner wall of the toner collection chamber 131 and at the chamber opening 131b due to the temperature rise, causing image contamination, abnormal noises and other abnormalities.

[0074] Currently, most solutions to prevent toner clumping in the toner collection chamber either leave it untreated or add a heat dissipation control strategy. Without any treatment, the risk remains; once toner clumping occurs in the toner collection chamber 131, the device can only be restored to function through after-sales service. Adding a heat dissipation control strategy can reduce the risk of clumping, but triggering the strategy requires stopping the image forming equipment 1 and turning on the fan, impacting the user experience.

[0075] Please continue to refer to this. Figure 2 and Figure 3 To address the aforementioned technical problems, in this embodiment, the toner conveying mechanism 13 further includes a rotating member 132 and a cleaning member 133. The rotating member 132 is disposed in the receiving cavity 131a and is rotatable relative to the toner collection chamber 131. The rotating member 132 can convey the toner in the receiving cavity 131a to the toner bottle. When viewed along the axis of the rotating member 132, the cleaning member 133 is at least partially located between the receiving cavity 131a and the rotating member 132, and the cleaning member 133 can be pushed to reciprocate along the axial direction of the rotating member 132.

[0076] In this embodiment, when the image forming apparatus 1 starts operating, the rotating member 132 can rotate relative to the toner collection chamber 131. Simultaneously, the cleaning member 133 can be pushed to reciprocate along the axial direction of the rotating member 132 (similar to piston movement). During the reciprocating motion of the cleaning member 133 within the receiving cavity 131a, the cleaning member 133 can pulverize any toner that may be agglomerated or is about to agglomerate within the receiving cavity 131a, so that the rotating member 132 can evenly deliver the toner to the toner bottle. This cycle ensures that the toner collection chamber 131 can continuously collect toner, thereby guaranteeing the normal operation of the image forming apparatus 1.

[0077] This embodiment effectively prevents toner from clumping inside the toner collection chamber 131 by incorporating a rotating component 132 and a cleaning component 133 within the toner collection chamber 131, significantly reducing the risk of clumping without affecting the user experience. Furthermore, it avoids expanding the overall structure of the toner delivery mechanism 13, facilitating the miniaturization of the image forming device 1.

[0078] The cleaning component 133 can be ring-shaped and can be sleeved on the outer periphery of the rotating component 132, that is, the rotating component 132 is the supporting structure for the cleaning component 133. While the rotating component 132 rotates, it can drive the cleaning component 133 to reciprocate along the axis of the rotating component 132 (the following describes in detail how the rotating component 132 drives the cleaning component 133 to reciprocate).

[0079] Alternatively, in other embodiments, the toner conveying mechanism 13 may further include a support component and a drive assembly. The cleaning component 133 may be sleeved on the support component, and the drive assembly drives the cleaning component 133 to reciprocate along the axial direction of the rotating component 132. The specific configuration can be adjusted according to actual conditions to achieve the reciprocating movement of the cleaning component 133 along the axial direction of the rotating component 132, thereby crushing agglomerated toner. This embodiment does not impose any limitations on this aspect.

[0080] Please continue to refer to this. Figure 3 During the reciprocating movement of the cleaning component 133 along the axial direction of the rotating component 132, the outer peripheral wall of the cleaning component 133 comes into frictional contact with the inner side wall of the toner collection chamber 131.

[0081] Specifically, in this embodiment, the cleaning component 133 is disposed within the receiving cavity 131a, and the outer wall of the cleaning component 133 is in contact with the inner wall of the toner collection chamber 131. When the rotating component 132 drives the cleaning component 133 to reciprocate along the axial direction of the rotating component 132, the outer peripheral wall of the cleaning component 133 can rub against the inner wall of the toner collection chamber 131, so that the cleaning component 133 can impact the toner powder clumps on the inner wall of the toner collection chamber 131 during the movement, thereby breaking up the toner powder clumps on the inner wall of the toner collection chamber 131, so that the pulverized toner powder can be conveyed out of the receiving cavity 131a by the rotating component 132.

[0082] Alternatively, by making frictional contact between the outer peripheral wall of the cleaning component 133 and the inner side wall of the toner collection chamber 131, the risk of toner agglomeration in the toner collection chamber 131 is reduced, so as to ensure that the toner collection chamber 131 can circulate and transport toner.

[0083] Please continue to refer to this. Figure 3 The cleaning component 133 is provided with a protrusion 133a, which is located at the opening 131b.

[0084] Specifically, in this embodiment, the cleaning component 133 is disposed within the receiving cavity 131a, and the protrusion 133a of the cleaning component 133 extends to the opening 131b. When the rotating component 132 drives the cleaning component 133 to reciprocate along the axial direction of the rotating component 132, the protrusion 133a of the cleaning component 133 also reciprocates at the opening 131b, so that the protrusion 133a can impact the carbon powder clumps at the opening 131b, thereby breaking up the carbon powder clumps at the opening 131b, so that the pulverized carbon powder can enter the receiving cavity 131a.

[0085] Alternatively, by having the protrusion 133a move back and forth at the opening 131b, the risk of clumping at the opening 131b is reduced, thus ensuring that the opening 131b can properly collect toner.

[0086] Please continue to refer to this. Figure 3 In some embodiments, the cleaning member 133 may be configured as a cam shape, so that the cleaning member 133 can be sleeved on the outside of the rotating member 132, and the outer peripheral wall of the cleaning member 133 can rub against the inner side wall of the toner collection chamber 131. The cleaning member 133 also has a protruding portion located at the chamber opening 131b.

[0087] Alternatively, in other embodiments, the cleaning component 133 may be configured with other structures, which can be set according to the actual situation. This embodiment is limited in this respect.

[0088] Please continue to refer to this. Figure 3 The protrusion 133a of the cleaning component 133 can extend to contact the transfer belt 121, so that the protrusion 133a can contact the toner at the opening 131b as much as possible, thereby improving the effect of dispersing the toner at the opening 131b.

[0089] In this embodiment, the cleaning component 133 may be made of an elastic material, so that the cleaning component 133 is elastic, thereby reducing the risk of the cleaning component 133 scratching the transfer belt 121 and ensuring that the transfer belt 121 works normally.

[0090] Figure 4 This is a schematic diagram showing the interaction between the rotating component 132 and the cleaning component 133. Figure 5This is a cross-sectional view of the mating position of the rotating component 132 and the cleaning component 133. Figure 6 for Figure 3 Please refer to the enlarged image of part A. Figure 4 , Figure 5 and Figure 6 The outer side wall of the rotating component 132 is provided with a guide rail 132a, and the cleaning component 133 is provided with a sliding part 133b that slides with the guide rail 132a. When the rotating component 132 rotates, the inner side wall of the guide rail 132a can guide the sliding part 133b to move along the guide rail 132a, so as to push the cleaning component 133 to reciprocate along the axial direction of the rotating component 132.

[0091] Specifically, in this embodiment, the cleaning component 133 is sleeved on the outside of the rotating component 132. The cleaning component 133 has a protruding sliding portion 133b facing the rotating component 132 on its side near the rotating component 132. The outer wall of the rotating component 132 has a recessed guide rail 132a, and the sliding portion 133b slides in cooperation with the guide rail 132a. That is, when the rotating component 132 rotates, the sliding portion 133b can move along the guide rail 132a.

[0092] In addition, the guide rail 132a is arranged in a circumferential manner on the outer wall of the rotating member 132, that is, the guide rail 132a forms a closed loop structure on the outer wall of the rotating member 132, so that the cleaning member 133 can reciprocate along the guide rail 132a.

[0093] Therefore, when the rotating component 132 rotates, the inner wall of the guide rail 132a can push the sliding part 133b to move along the guide rail 132a, and the sliding part 133b drives the cleaning component 133 to move, thereby realizing the circumferential reciprocating motion of the cleaning component 133 along the rotating component 132.

[0094] Please continue to refer to the reference. Figure 3 and Figure 4 The cleaning scraper 134 is disposed near the protrusion 133a, and the cleaning scraper 134 can restrict the cleaning component 133 from rotating with the rotating component 132.

[0095] In this embodiment, by placing the cleaning scraper 134 close to the protrusion 133a, when the cleaning component 133 is about to rotate with the guide rail 132a, the cleaning scraper 134 can abut against the protrusion 133a. That is, the cleaning scraper 134 restricts the rotation of the protrusion 133a, thereby restricting the rotation of the cleaning component 133. This allows the cleaning component 133 to move only along the axial direction of the rotating component 132 under the push of the inner wall of the guide rail 132a, thereby ensuring that the protrusion 133a can continuously reciprocate at the opening 131b, reducing the risk of toner agglomeration at the opening 131b.

[0096] Please continue to refer to this. Figure 4In some embodiments, the guide rail 132a may be spiral-shaped, so that when the rotating member 132 rotates, the inner sidewall of the guide rail 132a can apply a certain thrust to the sliding part 133b to push the sliding part 133b to move.

[0097] Understandable. Figure 4 The shape and number of spiral turns of the guide rail 132a shown are only examples. The specific shape and number of spiral turns of the guide rail 132a can be set according to the actual situation. This embodiment does not limit them here.

[0098] Alternatively, in other embodiments, the guide rail 132a may be configured in other shapes as long as it can guide the sliding part 133b of the cleaning component 133 to move. This embodiment does not impose specific limitations here.

[0099] Please refer to Figure 7 , Figure 7 The diagram shows a cross-sectional view of the structure of the toner conveying mechanism 13. The rotating component 132 includes a support part 132b, and a cleaning part 133 is sleeved on the outer ring of the support part 132b and can reciprocate along the axial direction of the support part 132b.

[0100] In this embodiment, the support portion 132b can be a cylindrical structure, and the support portion 132b can be arranged in a spiral shape (not shown in the figure) to match the position of the guide rail 132a, so as to reduce the space occupied by the support portion 132b. That is to say, part of the structure of the support portion 132b can be arranged in a spiral structure, and a spiral guide rail 132a is provided on the spiral support portion 132b.

[0101] Please continue to refer to this. Figure 7 The rotating component 132 also includes a driven part 132c, which is connected to the support part 132b. The toner conveying mechanism 13 also includes a drive gear 135, which engages with the driven part 132c.

[0102] In this embodiment, the drive gear 135 is used to cooperate with the drive component (not shown in the figure) on the device body 11. The drive gear 135 is sleeved on the outer periphery of the driven part 132c, and the driven part 132c is connected to the support part 132b. When the image forming apparatus 1 is working, the drive component drives the drive gear 135 to rotate, the drive gear 135 drives the driven part 132c to rotate, the driven part 132c drives the support part 132b to rotate, and during the rotation of the support part 132b, the cleaning component 133 is driven to reciprocate along the axial direction of the support part 132b, thereby realizing the operation of the cleaning component 133.

[0103] The driven part 132c and the supporting part 132b can be integrally formed to simplify the manufacturing process of the rotating component 132. Alternatively, the driven part 132c and the supporting part 132b can be separate structures to simplify the manufacturing process of the rotating component 132.

[0104] Please continue to refer to this. Figure 7 The toner conveying mechanism 13 also includes a stirring member 136. The rotating member 132 has a receiving space 132e communicating with the receiving cavity 131a. The stirring member 136 is installed in the receiving space 132e and can rotate with the rotating member 132. The side of the support part 132b away from the driven part 132c is an opening structure (not shown in the figure) communicating with the receiving space 132e. The opening structure is correspondingly provided with the toner bottle, and the toner in the receiving space 132e can be conveyed to the toner bottle through the opening structure.

[0105] In this embodiment, the toner in the receiving cavity 131a can enter the receiving space 132e, and as the stirring member 136 rotates, the toner can be transported to the toner bottle by the stirring member 136.

[0106] Please continue to refer to this. Figure 7 The rotating member 132 is also provided with a connecting part 132d, which is disposed in the accommodating space 132e. One end of the stirring member 136 is connected to the connecting part 132d so that the stirring member 136 can rotate together with the rotating member 132. The other end of the stirring member 136 is a free end, which can be located at the opening structure of the support part 132b.

[0107] In this embodiment, by providing a connecting part 132d in the receiving space 132e of the rotating member 132 to connect the stirring member 136, the stirring member 136 can rotate together with the rotating member 132, eliminating the need to provide a driving structure for the stirring member 136 and simplifying the structure.

[0108] In some embodiments, the stirring member 136 can be a helical spring structure, and as the stirring member 136 rotates, the toner is pushed out by the stirring member 136. Alternatively, the stirring member 136 can be configured with other shapes, which are not limited in this embodiment.

[0109] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
