Description

TECHNICAL FIELD

[0001] The utility model relates to electronic imaging device field, especially a general processing box. BACKGROUND

[0002] Electronic imaging devices form images on recording materials by using electrophotographic imaging types. Electronic imaging devices include electrophotographic copiers, electrophotographic printers (LED printers, laser beam printers, etc.), facsimile machines, etc. Generally, electronic imaging devices have detachable processing cartridges for providing printing consumables (developer) to the electronic imaging devices to complete the imaging process.

[0003] In current electronic imaging devices, OEMs (Original Equipment Manufacturers) face an important challenge: different models of electronic imaging devices have specific requirements for the size, shape, and interface design of processing cartridges. This results in each model of electronic imaging device requiring a processing cartridge with a specific design, especially the conductive end cap and gear cover part, which must be precisely matched to ensure correct installation and stable operation of the processing cartridge in the electronic imaging device.

[0004] However, this highly customized design has significant negative effects: different models of processing cartridges cannot be used universally, increasing user replacement costs. With the rise of environmental awareness and the popularization of resource recycling concepts, the recycling and reuse of waste processing cartridges have gradually become the focus of the industry. However, due to model incompatibility, the recycling of waste processing cartridges faces significant challenges, with a large number of waste processing cartridges being discarded due to model mismatch, causing resource waste and environmental pollution. Taking the HP brand as an example, HP1003, HP1105, HP1106, HP1007, HP1160, HP1100, HP1660, etc. Due to the slight differences in the design of the appearance structure of the processing cartridges corresponding to the electronic imaging devices, they cannot be directly interchanged. This not only increases user replacement costs but also increases the classification and processing difficulty for recycling companies.

[0005] Therefore, a technical solution is needed to solve the above problems. INVENTION CONTENTS

[0006] In order to solve the technical problems existing in the prior art, the purpose of the utility model is to provide a general processing cartridge to solve the above technical problems.

[0007] In order to achieve its purpose, the utility model adopts the following technical solutions:

[0008] A general processing cartridge is detachably installed in different models of electronic imaging devices with slide rail protrusions, characterized in that the general processing cartridge comprises:

[0009] A cartridge body for containing developer;

[0010] A cover is arranged at the end of the cartridge body, and the cover is provided with an extension part extending along the length direction of the universal process cartridge, and the extension part and the cartridge body form a clearance;

[0011] When the universal process cartridge is installed into the electronic imaging device, the clearance is not in contact with the slide rail protrusion.

[0012] In some embodiments, the cartridge body is provided with a recess matched with the extension part, and the extension part and the recess form the clearance when the cover is installed at the end of the cartridge body.

[0013] In some embodiments, the extension part does not exceed the edge of the cover in the height direction of the universal process cartridge.

[0014] In some embodiments, the recess is provided with an opening in the length direction of the cartridge body for the extension part to extend into.

[0015] In some embodiments, the recess is further provided with a side surface.

[0016] In some embodiments, the cover is detachably installed at the end of the cartridge body; or the cover is integrally formed with the cartridge body.

[0017] In some embodiments, the cover is further provided with a positioning part.

[0018] In some embodiments, the positioning part is a protrusion of the cover protruding outwardly along the length direction of the cartridge body, and when the universal process cartridge is installed into the electronic imaging device, the protrusion moves along the guide rail of the electronic imaging device to guide the installation of the universal process cartridge.

[0019] The universal process cartridge in the utility model ingeniously extends the extension part of the cover to the cartridge body of the universal process cartridge, and forms a clearance by cooperating with the recess on the cartridge body, so that the universal process cartridge can not interfere with the slide rail protrusion on various electronic imaging devices. This design not only simplifies the conversion process between different models of process cartridges, but also enables the universalization of different models of process cartridges by simply replacing the cover and cutting the recess of the process cartridge, thereby significantly improving the universality and reusability of the process cartridge and effectively solving the recycling problem of waste process cartridges caused by model differences. This not only helps to save resources and reduce environmental pollution, but also promotes the sustainable development of the process cartridge recycling industry.

[0020] In addition, the implementation of the technical scheme also reduces the production cost of OEM manufacturers and recycling enterprises, enhances the market competitiveness, and provides a new idea and direction for the recycling of electronic imaging devices and their consumables.BRIEF DESCRIPTION OF DRAWINGS BRIEF DESCRIPTION OF DRAWINGS

In addition, those skilled in the art can combine and combine different embodiments or examples described in the specification and the features of different embodiments or examples without contradiction.

[0036] As shown in Figures 1 to 8 A general processing cartridge is provided, which stores a developer therein, and can be detachably mounted in different models of electronic imaging devices (such as electronic imaging devices with or without slide rail protrusions), and the electronic imaging devices can perform imaging work using the developer in the general processing cartridge.

[0037] In this manual, to better explain the various components of the general processing box, the length direction of the general processing box is configured as the X-axis direction, the width direction as the Y-axis direction, and the height direction as the Z-axis direction. The X-axis, Y-axis, and Z-axis directions are perpendicular to each other.

[0038] The universal processing cartridge includes a developing unit and a photosensitive unit. The developing unit and the photosensitive unit are integrated and fixed together by pins or screws to form an integrated processing cartridge.

[0039] The developing unit includes a developing frame 110, a developing roller, a powder feeding roller, and a stirring frame. The photosensitive unit includes a photosensitive frame 120, a photosensitive drum, and a charging roller.

[0040] The developing frame 110 includes a toner hopper for storing toner. The developing frame 110 is a long, rectangular box shape, with end faces at both ends along its length. A stirring rack, a toner delivery roller, and a developing roller are rotatably supported on the developing frame 110. These components can rotate under the driving force of a drive gear; that is, the axial directions of the stirring rack, toner delivery roller, and developing roller are all along the length of the developing frame 110. The toner in the hopper is agitated by the stirring rack to prevent agglomeration, and the stirring rack also conveys the toner towards the toner delivery roller, which then delivers the toner to the developing roller where it is attracted by the charged developing roller.

[0041] like Figure 1 As shown, the length direction of the photosensitive frame 120 is aligned with the length direction of the developing frame 110. The photosensitive drum is rotatably supported on the photosensitive frame 120. The photosensitive frame 120 and the developing frame 110 are fixedly connected by pins or screws to form the housing of the universal processing cartridge. Within the housing composed of the developing unit and the photosensitive unit, the developing roller and the photosensitive drum are in contact with each other. The toner adsorbed by the developing roller is transferred to the photosensitive drum through the potential difference between the developing roller and the photosensitive drum. The toner on the photosensitive drum is then transferred by an electro-imaging device to form an image on a recording material (e.g., paper). The charging roller is used to uniformly charge the surface of the photosensitive drum, giving it a charge capable of adsorbing toner.

[0042] The general processing cartridge further comprises a gear assembly comprising a plurality of gears for receiving driving force from the driving gear of the electronic imaging device to drive the rotating components such as the developing roller to rotate and make the general processing cartridge work. For example, the gear assembly comprises a photosensitive drum gear, a developing roller gear, a powder feeding roller gear, a stirring frame gear and the like. After the general processing cartridge is installed to the imaging device, the photosensitive drum gear is engaged with the driving gear of the electronic imaging device to receive driving force. The developing roller gear, the powder feeding roller gear and the stirring frame gear are respectively arranged at one end of the developing roller, the powder feeding roller and the stirring frame, and the photosensitive drum gear, the developing roller gear, the powder feeding roller gear and the stirring frame gear can be engaged with each other to transmit driving force, so that the driving force of the electronic imaging device can be transmitted to the developing roller, the powder feeding roller and the stirring frame to make the developing unit transmit developer to the photosensitive unit.

[0043] Preferably, the gear assembly can be arranged at one end or both ends of the general processing cartridge in the length direction. In the embodiment, the photosensitive drum gear, the developing roller gear, the powder feeding roller gear and the stirring frame gear of the gear assembly are arranged at the same end of the general processing cartridge in the length direction.

[0044] The electronic imaging device is provided with a mounting portion, wherein the inner wall of the mounting portion is provided with a guide rail. The general processing cartridge is provided with a positioning portion 220, which can move along the guide rail to make the general processing cartridge correctly installed in the electronic imaging device.

[0045] Specifically, in the embodiment, the cartridge body has a first end 100a and a second end 100b arranged oppositely in the length direction, a third end 100c and a fourth end 100d arranged oppositely in the width direction, and a fifth end 100e and a sixth end 100f arranged oppositely in the height direction. The first end 100a and the second end 100b of the cartridge body of the general processing cartridge are both provided with the positioning portion 220, and the corresponding positions of the mounting portion of the electronic imaging device are both provided with the guide rail. During the installation of the general processing cartridge to the electronic imaging device, the positioning portions 220 arranged at both ends of the cartridge body can move along the guide rail to guide the installation of the general processing cartridge in the mounting portion, so that the general processing cartridge is installed in place in the electronic imaging device and the printing is completed.

[0046] The specific structure and working mode of the electronic imaging device (not shown) and the general processing cartridge are prior art, which will not be described herein. In the present application, only the structure and working process of the general processing cartridge cooperating with the electronic imaging device to drive are disclosed.

[0047] Reference Figures 1 to 8 In the embodiment, the general processing cartridge is further provided with a clearance portion 130 for avoiding the sliding rail protrusion arranged in the mounting portion of the electronic imaging device when the general processing cartridge is installed to the electronic imaging device, so that the general processing cartridge can be used in the electronic imaging device with or without the sliding rail protrusion.

[0048] With reference to Figure 1 The gear assembly can be arranged at one end or both ends of the universal processing cartridge in the length direction, and the protective cover 200 is arranged outside the gear assembly and can protect the gear assembly, i.e., in the +X direction, the protective cover 200 is arranged at the front side of the gear assembly.

[0049] Specifically, in the present embodiment, the gear assembly is arranged at the first end 100a of the cartridge body, and the protective cover 200 is also arranged at the first end 100a and outside the gear assembly to protect the gear assembly. Alternatively, in some other embodiments, the gear assembly and the protective cover 200 can also be arranged at the second end 100b of the cartridge body.

[0050] Preferably, the protective cover 200 is detachably fixedly mounted at the first end 100a of the cartridge body, for example, the protective cover 200 is detachably mounted at the first end 100a of the cartridge body through bolts or buckle structures, and the protective cover 200 covers at least the gear assembly and is used to protect the gear assembly.

[0051] Alternatively, in some other embodiments, the protective cover 200 can be integrally formed with the cartridge body.

[0052] When the protective cover 200 is mounted at the end of the cartridge body, it is used to cover at least part of the end of the developing frame 110 and the end of the photosensitive frame 120. Preferably, when the protective cover 200 is mounted at the cartridge body, it is located at the +X axis side of the developing frame 110 and the +X axis side of the photosensitive frame 120, can be used to connect the developing frame 110 and the photosensitive frame 120, and in the present embodiment, the protective cover 200 can completely cover the first end 100a of the developing frame 110 and the first end 100a of the photosensitive frame 120, and when viewed in the length direction of the universal processing cartridge, the protective cover 200 at least partially overlaps the first end 100a of the cartridge body.

[0053] Preferably, the first end 100a of the developing frame 110 is the first end 100a of the cartridge body, and the protective cover 200 is detachably fixedly mounted at the first end 100a of the developing frame 110.

[0054] With reference to Figure 2 and Figure 3 The clearance 130 is arranged between the end of the cartridge body and the protective cover 200, and when the universal processing cartridge is mounted to the electronic imaging device, the position of the clearance 130 corresponds to the slide rail protrusion of the electronic imaging device, and the clearance 130 can avoid the slide rail protrusion in the electronic imaging device, i.e., the clearance and the slide rail protrusion maintain a distance and do not contact each other. Preferably, the clearance 130 is located at the inner side of the protective cover 200 (the -X axis side) in the X axis direction.

[0055] Preferably, the clearance 130 is a recess formed in the sixth end 100f of the cartridge body, and the clearance 130 has a dimension in the X-axis direction greater than that of the slide rail protrusion in the X-axis direction, so that the clearance 130 can completely avoid the slide rail protrusion.

[0056] With reference to Figure 5 - Figure 8 The cover 200 is provided with an extension 210 on the inner side (-X-axis side), and the cartridge body is also provided with a recess 111, when the cover 200 is installed on the end of the cartridge body, the extension 210 cooperates with the recess 111 to form a clearance 130 for avoiding the slide rail protrusion in the electronic image forming device.

[0057] Preferably, the recess 111 is a recess formed in the sixth end 100f of the developing frame 110 along the +Z-axis direction, and is located at the first end 100a of the developing frame 110, and the recess 111 is provided with a side surface 111a in the X-axis direction, wherein the recess 111 further has an opening for the extension 210 to be inserted from the X-axis direction.

[0058] Preferably, the extension 210 does not protrude beyond the two ends of the cover 200 in the Y-axis direction, that is, the projection of the extension 210 in the Y-axis direction falls entirely within the cover 200.

[0059] Alternatively, in some other embodiments, the projection of the extension 210 in the Y-axis direction at least partially falls within the cover 200.

[0060] Preferably, as shown in Figure 7 viewed in the height direction of the universal process cartridge, the extension 210 does not protrude beyond the edge 200a of the cover, that is, the extension 210 is located on the +Z-axis side of the edge 200a of the cover.

[0061] Preferably, the bottom of the recess 111 is also a hollow structure, and when the cover 200 is installed on the cartridge body, the extension 210 is used to shield the hollow structure of the bottom of the recess 111, so that the clearance 130 is not in communication with the inside of the cartridge body.

[0062] Preferably, the clearance 130 is arranged on the side of the developing frame 110 away from the photosensitive frame 120 in the height direction (i.e. along the Z-axis direction), that is, the clearance 130 is arranged on the sixth end 100f of the cartridge body, so that when it is installed on the electronic image forming device, the clearance 130 will not interfere with the slide rail protrusion, so as to avoid interference between the universal process cartridge and the slide rail protrusion, and affect the installation.

[0063] Specifically, in the present embodiment, the extension 210 is a plate-shaped structure of the cover 200 extending along the X-axis direction on the side close to the end of the cartridge body, and the recess 111 is a substantially square-shaped through hole cut on the bottom of the first end 100a of the developing frame 110; when the cover 200 is installed on the cartridge body, the extension 210 is inserted into the recess 111 from the opening of the recess 111 along the X-axis direction, at this time, the extension 210 is used to form the bottom of the avoidance portion 130, while the edge 200a of the cover 200 and the side surface 111a of the recess 111 form two side walls of the avoidance portion 130 in the X-axis direction, i.e. the avoidance portion 130 for avoiding the slide rail protrusion of the electronic imaging device is formed between the cartridge body and the cover 200. As shown in Figure 8 illustrated, when viewed along the width direction of the universal processing cartridge, in the -Z-axis direction, the extension 210 does not protrude from the side surface 111a and the edge 200a.

[0064] At the first end 100a of the universal processing cartridge, the positioning portion 220 is arranged on the cover 200. Specifically, the positioning portion 220 is a protrusion protruding along the +X-axis direction on the opposite side of the mounting surface of the cover 200 matched with the cartridge body, when the universal processing cartridge is installed on the electronic imaging device, the protrusion can be moved along the slide rail to guide the installation of the universal processing cartridge.

[0065] It is worth noting that in order to correctly install the universal processing cartridge at both ends in the length direction, the universal processing cartridge needs to be provided with the positioning portion 220 at both ends in the length direction for guidance, and the positioning portion 220 at the second end 100b of the cartridge body can be a protrusion protruding along the -X-axis of the cartridge body, or a protrusion arranged on the cover 200 arranged at the second end 100b of the cartridge body, which is not limited here.

[0066] It can be understood that the above-mentioned universal processing cartridge can be a recycled processing cartridge remanufactured, or a brand-new processing cartridge, which is not limited here.

[0067] The recycled processing cartridge remanufacturing method can be, for example, replacing the cover 200 of HP1003, HP1105, HP1106, HP1007 and HP1160 models with the cover 200 with the extension 210, and cutting the recess 111 as shown in Figure 6 on the powder tank to adapt to the cover 200. Figure 4 .

[0068] Reference Figure 2 - Figure 8After the cover 200 is installed on the box body, the avoidance portion 130 is formed by the recessed portion side surface 111a of the box body, the cover edge 200a and the extension portion 210 of the cover 200, and the avoidance portion 130 does not interfere with the slide rail protrusion in the imaging device corresponding to the HP1100 / HP1660 model, so that the universal processing cartridge is normally installed, and the toner cartridges of different models but similar appearance are universalized.

[0069] The use mode of the universal processing cartridge installed on the electronic imaging device is as follows:

[0070] The positioning portion 220 of the universal processing cartridge is aligned with the guide rail in the mounting portion of the electronic imaging device, the universal processing cartridge is pushed to move along the guide rail, and meanwhile, since the avoidance portion 130 does not interfere with the slide rail protrusion, the universal processing cartridge can be smoothly installed in place.

[0071] The universal processing cartridge in the utility model, the extension portion 210 of the cover 200 is extended to the box body of the universal processing cartridge, and the avoidance portion 130 is formed by cooperating with the recessed portion 111 on the box body, so that the avoidance portion 130 can avoid interference with the slide rail protrusion on various electronic imaging devices when the universal processing cartridge is installed in the electronic imaging device. This design not only simplifies the conversion process between different models of processing cartridges, but also only needs to replace the cover 200 and cut the recessed portion 111 of the processing cartridge, so that the universalization of different models of processing cartridges can be realized, the universality and reusability of the processing cartridge are significantly improved, and the problem of waste processing cartridge recycling caused by model difference is effectively solved. This is not only beneficial to save resources and reduce environmental pollution, but also promotes the sustainable development of the processing cartridge recycling industry.

[0072] The above only describes some embodiments of the utility model. For ordinary skilled persons in the art, without departing from the creative concept of the utility model, a number of modifications and improvements can be made, and these all belong to the protection scope of the utility model.
