Description

Technical Field

[0001] This utility model relates to the field of image forming equipment technology, and in particular to a processing box and an image forming device. Background Technology

[0002] In image forming equipment such as printers and copiers, the processing cartridge is the core component for image development, and it is usually assembled from multiple housings (such as toner cartridge housing and waste toner cartridge housing). In existing technology, the housings are usually installed through positioning holes between them. Precise alignment is required during assembly, which leads to long alignment time, reduced assembly efficiency, and significant deformation of the housings during installation and pushing. This can cause misalignment of the internal imaging components, reduced housing sealing performance, and ultimately affect the imaging quality of the processing cartridge and shorten its service life. Utility Model Content

[0003] This utility model provides a processing box and an image forming device that can quickly install a first housing and a second housing, improve positioning accuracy, and reduce the deformation of the first housing and the second housing.

[0004] In a first aspect, embodiments of the present invention provide a processing box for use in an image forming apparatus. The processing box includes a first housing and a second housing. The first housing includes a first end face and a second end face disposed opposite to each other along a first direction. The first end face includes a first protrusion, and the second end face includes a second protrusion. The first direction is parallel to the length direction of the processing box. The second housing includes a third end face and a fourth end face disposed opposite to each other along the first direction. The third end face includes a first positioning portion, which is detachably connected to the first protrusion. The fourth end face includes a second positioning portion, which is detachably connected to the second protrusion. The first protrusion and the second protrusion are respectively engaged with the first positioning portion and the second positioning portion to detachably connect the first housing and the second housing.

[0005] This utility model's technical solution involves providing a first protrusion on the first end face of the first housing and a first positioning part on the third end face of the second housing, with the first protrusion and the first positioning part being detachably matched and connected. It also involves providing a second protrusion on the second end face of the first housing and a second positioning part on the fourth end face of the second housing, with the second protrusion and the second positioning part being detachably matched and connected. This allows for a detachable connection between the first and second housings. Through the cooperative structure of the protrusion and the positioning part, when the first and second housings of the processing box need to be assembled, or when toner needs to be replenished or parts replaced, the first and second housings can be quickly assembled or separated, improving installation and positioning accuracy, shortening installation and disassembly time, increasing assembly and maintenance efficiency, and reducing the deformation of the first and second housings.

[0006] According to the aforementioned embodiment of the first aspect of this utility model, the first positioning part is provided with a first bending groove, a second bending groove, and a third protrusion in sequence along a second direction, wherein the second direction is parallel to the width direction of the processing box. The first bending groove is located near the side where the second housing is located, the third protrusion is located near the side where the first housing is located, and the second bending groove is located between the first bending groove and the third protrusion. When the first housing and the second housing are connected, the first protrusion slides sequentially along the first bending groove and the second bending groove, so that the second bending groove and the third protrusion engage the first protrusion. The technical solution of this utility model, by providing a first bending groove, a second bending groove, and a third protrusion, with the first bending groove providing a guide for the first protrusion, allows the first protrusion to slide in firstly through the first bending groove during assembly, and then be engaged at the third protrusion via the second bending groove. This quickly positions the first housing and the second housing during installation, improving the accuracy of installation positioning, shortening installation and disassembly time, improving assembly and maintenance efficiency, and reducing the deformation of the first housing and the second housing.

[0007] According to the aforementioned embodiment of the first aspect of this utility model, the first protrusion includes a cylindrical protrusion, and the inner walls of the first bending groove and the second bending groove have an arc-shaped structure that matches the outer peripheral shape of the first protrusion. This utility model's technical solution ensures good fit accuracy and force distribution at the contact surfaces between the first protrusion and the first and second bending grooves by providing an arc-shaped structure matching the outer peripheral shape of the first protrusion on the inner walls of the first and second bending grooves.

[0008] According to the aforementioned embodiment of the first aspect of this utility model, the second housing is further provided with an elastic member. The elastic member is located at the abutment point between the second housing and the first housing and is disposed near the side where the first positioning part is located. When the first housing and the second housing are connected, the first housing compresses the elastic member, causing the first protrusion to be engaged within the first positioning part. This utility model's technical solution, by providing an elastic member at the abutment point between the second housing and the first housing, and by placing the elastic member near the side where the first positioning part is located, helps to avoid mutual compression between the first housing and the second housing during assembly, and reduces the degree of deformation of the first housing and the second housing.

[0009] According to the aforementioned embodiment of the first aspect of this utility model, the second positioning part includes a first positioning hole. When the first housing and the second housing are connected, the second protrusion is engaged in the first positioning hole. The processing box also includes a first transmission head, which is disposed on the second protrusion and is connected to the rotatable imaging component in the processing box. This utility model's technical solution, by providing a first positioning hole in the second positioning part, facilitates quick installation between the first housing and the second housing when the first housing and the second housing are connected, allowing the second protrusion to engage in the first positioning hole.

[0010] According to the aforementioned embodiment of the first aspect of this utility model, the processing box further includes a second transmission head, which is connected to a rotatable imaging component in the processing box. The second positioning part includes a second positioning hole, and when the first housing and the second housing are connected, the second transmission head is engaged in the second positioning hole. This utility model's technical solution, by providing a second positioning hole in the second positioning part, allows the second transmission head to be engaged in the second positioning hole when the first housing and the second housing are connected, which helps improve the positioning accuracy between the first housing and the second housing.

[0011] According to the aforementioned embodiment of the first aspect of this utility model, the second positioning hole is an oblong hole, which provides a preset space for the movement of the second transmission head. By setting the second positioning hole to an oblong hole, this utility model provides a preset space for the movement of the second transmission head during installation. The oblong hole can compensate for assembly errors of the second transmission head and improve positioning accuracy, enhance the coaxiality of the imaging components, improve development quality, and facilitate guidance during assembly while ensuring final positioning accuracy.

[0012] According to the aforementioned embodiment of the first aspect of this utility model, a cover plate is provided on the fourth end face, and the first positioning hole and the second positioning hole are respectively provided on the cover plate.

[0013] According to the aforementioned embodiments of the first aspect of this utility model, the cover plate and the second housing are integrally formed.

[0014] In a second aspect, embodiments of the present invention provide an image forming apparatus, including a processing box according to any of the foregoing embodiments of the first aspect of the present invention.

[0015] This utility model provides a processing box in an image forming apparatus. The processing box includes a first housing and a second housing.

[0023] This utility model provides a processing box and an image forming device that can quickly install a first housing and a second housing, improve positioning accuracy, and reduce the deformation of the first housing and the second housing.

[0024] like Figures 1 to 5 As shown, this utility model embodiment provides a processing box for use in an image forming device. The processing box includes a first housing 100 and a second housing 200. Specifically, the first housing 100 is a toner hopper housing for storing toner, and the second housing 200 is a waste toner hopper housing for collecting waste toner.

[0025] like Figures 1 to 3 As shown, the first housing 100 includes a first end face 110 and a second end face 120 disposed opposite to each other along a first direction S1. The first end face 110 includes a first protrusion 111, and the second end face 120 includes a second protrusion 121. The first direction S1 is parallel to the length direction of the processing box and is also the direction of the rotation axis of the rotatable imaging component (such as the developing roller, photosensitive drum, etc.) inside the processing box. The second housing 200 includes a third end face 210 and a fourth end face 220 disposed opposite to each other along the first direction S1. The third end face 210 includes a first positioning part 211, which is detachably connected to the first protrusion 111. The fourth end face 220 includes a second positioning part 221, which is detachably connected to the second protrusion 121. The first protrusion 111 and the second protrusion 121 are respectively connected to the first positioning part 211 and the second positioning part 221 to detachably connect the first housing 100 and the second housing 200.

[0026] This utility model's technical solution involves providing a first protrusion 111 on the first end face 110 of the first housing 100 and a first positioning part 211 on the third end face 210 of the second housing 200. The first protrusion 111 and the first positioning part 211 are detachably matched and connected. A second protrusion 121 is provided on the second end face 120 of the first housing 100, and a second positioning part 221 is provided on the fourth end face 220 of the second housing 200. The second protrusion 121 and the second positioning part 221 are detachably matched and connected, thereby detachably connecting the first housing 100 and the second housing 200. Through the cooperative structure of the protrusion and the positioning part, when the first housing 100 and the second housing 200 of the processing box need to be assembled, or when toner needs to be replenished or parts replaced, the first housing 100 and the second housing 200 can be quickly assembled or separated, improving installation and positioning accuracy, shortening installation and disassembly time, improving assembly and maintenance efficiency, and reducing the deformation of the first housing 100 and the second housing 200.

[0027] like Figure 5 As shown, the first positioning part 211 is provided with a first bending groove 2111, a second bending groove 2112, and a third protrusion 2113 sequentially along the second direction S2, wherein the second direction S2 is parallel to the width direction of the processing box. The first bending groove 2111 is located near the side where the second housing 200 is located and is inclined. The third protrusion 2113 is located near the side where the first housing 100 is located. The second bending groove 2112 is located between the first bending groove 2111 and the third protrusion 2113, and the second bending groove 2112 is also inclined. When the first housing 100 and the second housing 200 are connected, the first protrusion 111 slides sequentially along the first bending groove 2111 and the second bending groove 2112, so that the second bending groove 2112 and the third protrusion 2113 engage with the first protrusion 111. This utility model's technical solution involves setting a first bending groove 2111, a second bending groove 2112, and a third protrusion 2113. The first bending groove 2111 provides a guide for the first protrusion 111. During assembly, the first housing 100 is pushed relative to the second housing 200 along the second direction S2. During assembly, the first protrusion 111 is first guided into the first bending groove 2111, and then passes through the second bending groove 2112 to be locked at the third protrusion 2113. This allows for quick positioning of the first housing 100 and the second housing 200 during installation, improving installation positioning accuracy, shortening installation and disassembly time, increasing assembly and maintenance efficiency, and reducing the degree of deformation of the first housing 100 and the second housing 200.

[0028] like Figure 1 as well as Figure 4As shown, the first protrusion 111 includes a cylindrical protrusion, and the inner walls of the first bending groove 2111 and the second bending groove 2112 have an arc-shaped structure that matches the outer circumferential shape of the first protrusion 111. This utility model's technical solution ensures good fit accuracy and force distribution at the contact surfaces between the first protrusion 111 and the first bending groove 2111 and the second bending groove 2112 by providing an arc-shaped structure that matches the outer circumferential shape of the first protrusion 111 on the inner walls of the first bending groove 2111 and the second bending groove 2112.

[0029] like Figure 3 As shown, the second housing 200 is also provided with an elastic element 230, such as a spring or a sheet. The elastic element 230 is located at the point where the second housing 200 abuts against the first housing 100 and is located near the side where the first positioning part 211 is located. When the first housing 100 and the second housing 200 are connected, the first housing 100 compresses the elastic element 230, and the elastic element 230 generates a reaction force, driving the first housing 100 to move slightly away from the second bending groove 2112, so that the first protrusion 111 is engaged in the second bending groove 2112 and the third protrusion 2113. The present invention provides an elastic element 230 at the contact point between the second housing 200 and the first housing 100, and the elastic element 230 is located close to the side where the first positioning part 211 is located. This helps to avoid mutual squeezing between the first housing 100 and the second housing 200 during assembly, prevents the first protrusion 111 from loosening, and reduces hard contact between the first housing 100 and the second housing 200, thereby reducing the degree of deformation of the first housing 100 and the second housing 200.

[0030] like Figure 3 As shown, the second positioning part 221 includes a first positioning hole 2211. When the first housing 100 and the second housing 200 are connected, the second protrusion 121 is engaged in the first positioning hole 2211. The processing box also includes a first transmission head 300, which is disposed on the second protrusion 121. The first transmission head 300 is connected to a rotatable imaging component in the processing box, such as being connected to a photosensitive drum. This utility model's technical solution, by providing a first positioning hole 2211 in the second positioning part 221, facilitates quick installation between the first housing 100 and the second housing 200 when the first housing 100 and the second housing 200 are connected, as the second protrusion 121 is engaged in the first positioning hole 2211.

[0031] like Figure 3As shown, the processing box also includes a second drive head 400, which is driveably connected to a rotatable imaging component in the processing box, such as being driveably connected to a developing roller. The second positioning part 221 includes a second positioning hole 2212, in which the second drive head 400 is engaged when the first housing 100 and the second housing 200 are connected. This invention, by providing a second positioning hole 2212 in the second positioning part 221, allows the second drive head 400 to be engaged when the first housing 100 and the second housing 200 are connected, thus improving the positioning accuracy between the first housing 100 and the second housing 200.

[0032] like Figure 5 As shown, the second positioning hole 2212 is an oblong hole, providing a preset space for the movement of the second transmission head 400. This utility model's technical solution, by setting the second positioning hole 2212 as an oblong hole, provides a preset space for the movement of the second transmission head 400 during installation. The oblong hole can compensate for assembly errors of the second transmission head 400 and improve positioning accuracy, enhance the coaxiality of the imaging components, improve development quality, and facilitate guidance during assembly while ensuring final positioning accuracy.

[0033] like Figure 5 As shown, a cover plate 222 is provided on the fourth end face 220, and a first positioning hole 2211 and a second positioning hole 2212 are respectively provided on the cover plate 222. The relative position between the first transmission head 300 and the second transmission head 400 is determined by the hole positions of the first positioning hole 2211 and the second positioning hole 2212 on the cover plate 222. The cover plate 222 serves as an installation and positioning reference, ensuring that the axial and radial relationships of the first transmission head 300 and the second transmission head 400 match with the internal imaging components, thereby ensuring synchronous transmission of the imaging components and improving the positioning accuracy.

[0034] Preferably, the cover plate 222 and the second housing 200 are integrally formed to avoid assembly gaps and improve structural strength.

[0035] This utility model embodiment also provides an image forming apparatus, including a processing box according to any of the foregoing embodiments of this utility model.

[0036] like Figures 1 to 5As shown, this embodiment of the present invention provides a processing box for use in an image forming apparatus. The processing box includes a first housing 100 and a second housing 200. The first housing 100 includes a first end face 110 and a second end face 120 disposed opposite to each other along a first direction S1. The first end face 110 includes a first protrusion 111, and the second end face 120 includes a second protrusion 121. The first direction S1 is parallel to the length direction of the processing box. The second housing 200 includes a third end face 210 and a fourth end face 220 disposed opposite to each other along the first direction S1. The third end face 210 includes a first positioning portion 211, which is detachably connected to the first protrusion 111. The fourth end face 220 includes a second positioning portion 221, which is detachably connected to the second protrusion 121. The first protrusion 111 and the second protrusion 121 are respectively connected to the first positioning part 211 and the second positioning part 221 to detachably connect the first housing 100 and the second housing 200.

[0037] This utility model provides a processing box in an image forming apparatus. The processing box includes a first housing 100 and a second housing 200. A first protrusion 111 is provided on the first end face 110 of the first housing 100, and a first positioning part 211 is provided on the third end face 210 of the second housing 200. The first protrusion 111 and the first positioning part 211 are detachably connected. A second protrusion 121 is provided on the second end face 120 of the first housing 100, and a second positioning part 221 is provided on the fourth end face 220 of the second housing 200. The first housing 100 and the second housing 200 are detachably matched and connected. Through the cooperation structure between the protrusion and the positioning part, when the first housing 100 and the second housing 200 of the processing box need to be assembled, or when toner needs to be replenished or parts need to be replaced, the first housing 100 and the second housing 200 can be quickly assembled or separated, which improves the accuracy of installation and positioning, shortens the installation and disassembly time, improves the efficiency of assembly and maintenance, reduces the degree of deformation of the first housing 100 and the second housing 200, and improves the imaging quality of the image forming device.
