Description

Technical Field

[0001] This utility model relates to the field of imaging technology, specifically to a processing box and imaging device. Background Technology

[0002] The processing cartridge is an essential component of imaging equipment, generally comprising a photosensitive unit and a developing unit. The photosensitive unit typically includes a first end cap, a photosensitive drum, and a charging component. Both the photosensitive drum and the charging component are inserted into the first end cap, with the charging component in contact with the photosensitive drum to transmit power. The developing unit includes a second end cap, a developing roller, and a supply roller. Both the developing roller and the supply roller are inserted into the second end cap, and the supply roller supplies toner to the developing roller. Since the developing roller, supply roller, and charging component all require power during operation, the processing cartridge typically contains multiple electrodes that can be electrically connected to the power-conducting components of the imaging equipment. These electrodes are electrically connected to the developing roller, supply roller, and charging component to transmit power. This arrangement of multiple electrodes results in a complex internal structure for the processing cartridge, hindering production and assembly, increasing costs, and complicating power transmission paths. A failure in a single line directly affects the imaging process, impacting the efficiency, stability, and reliability of power transmission. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a processing box that can simplify the internal structure, reduce costs, and improve power transmission efficiency, stability and reliability.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A processing box includes a photosensitive unit, a developing unit, a supply roller, and a charging component. The photosensitive unit includes a first end cover and a photosensitive drum inserted into the first end cover. The developing unit includes a second end cover and a developing roller inserted into the second end cover. The supply roller and the charging component are both connected to the second end cover. The second end cover is a conductive end cover and is provided with a first electrical contact, a second electrical contact, and a third electrical contact. The first electrical contact, the second electrical contact, and the third electrical contact can all make electrical contact with the power-conducting components of the imaging device to transmit power to the developing roller, the supply roller, and the charging component.

[0005] Compared to existing technologies, the advantages of this invention are as follows: This processing box connects the developing roller, supply roller, and charging component to the same component, namely the second end cover. The second end cover is designed to be conductive, allowing the first, second, and third electrical contacts to be located on it, achieving electrical contact with the energized components of the imaging device while simultaneously supplying power to the developing roller, supply roller, and charging component. Therefore, this processing box can use the second end cover in the developing unit as an electrode, and integrate the first, second, and third electrical contacts onto the same component, thereby reducing the number of parts, simplifying the internal structure, and lowering costs. Power can be directly transmitted to the developing roller, supply roller, and charging component through the second end cover, improving power transmission efficiency. The overall conductivity of the second end cover greatly reduces the impact of single-line failures, improving the stability and reliability of power transmission.

[0006] In the aforementioned processing box, the second end cover is elastically connected to a fixing base, and the end of the charging component is connected to the fixing base.

[0007] The aforementioned processing box has a first connecting part on the second end cover and a second connecting part on the fixing base. A first elastic element connects the first connecting part and the second connecting part.

The second coupling is inserted into the drive side cover and can be connected to an imaging device to receive driving force. The rotatable component is rotatably connected to the drive side cover and includes a gear portion and a toothed portion. When the processing cartridge is in a non-working state, the gear part engages with the photosensitive drum gear to separate the photosensitive drum from the developing roller. When the processing cartridge needs to be in a working state, the drive side cover can drive the developing roller toward the photosensitive drum, and the photosensitive drum gear engages with the gear part to rotate until the photosensitive drum gear connects with the toothed part, at which point the developing roller contacts the photosensitive drum. When the processing cartridge needs to be in a non-working state again, the drive side cover is not driven, and the elastic reset member can reset the rotatable component to re-engage with the photosensitive drum gear.

[0010] The aforementioned processing box has a third connecting portion and a fourth connecting portion on the drive side cover, and a fifth connecting portion on the rotatable component. The rotatable component is rotatably sleeved on the third connecting portion. The elastic reset component includes a first sleeve portion and a first extension portion and a second extension portion respectively connected to both ends of the first sleeve portion. The first sleeve portion is sleeved on the third connecting portion, and the first extension portion and the second extension portion are respectively fixedly connected to the fourth connecting portion and the fifth connecting portion.

[0011] The aforementioned processing box, wherein the third connecting part includes a main body part and an elastic part, the first ends of the main body part and the elastic part are both fixedly connected to the drive side cover, and when the rotatable component and the first sleeve part are sleeved on the main body part and the elastic part, the elastic part can undergo elastic deformation relative to the main body part, and the second end of the elastic part is provided with a buckle.

[0012] The aforementioned processing box, wherein the photosensitive unit further includes a second elastic member, which is capable of pressing against the side of the photosensitive drum toward the first end cap.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below: Example 1 Reference Figures 1 to 8 Embodiment 1 of this utility model provides a processing box and an imaging device. The imaging device in this embodiment is similar to that in the prior art, having power-conducting components, including a DR power-conducting unit, an SR power-conducting unit, and a PCR power-conducting unit, for transmitting power to the developing roller 220, the supply roller 300, and the charging unit 400, respectively. It should be noted that in this embodiment, the DR power-conducting unit, the SR power-conducting unit, and the PCR power-conducting unit are the original structure of the imaging device, and this embodiment does not improve the power-conducting components of the imaging device.

[0019] The processing unit includes a photosensitive unit 100, a developing unit 200, a supply roller 300, and a charging component 400. The photosensitive unit 100 includes a first end cap 110 and a photosensitive drum 120 inserted into the first end cap 110. The developing unit 200 includes a second end cap 210 and a developing roller 220 inserted into the second end cap 210. The second end cap 210 has holes for inserting the developing roller 220 and the supply roller 300 to fix them together. The second end cap 210 also has a connection portion for connecting the charging component 400. The second end cap 210 is a conductive end cap made of conductive material and is conductive throughout. The second end cap 210 is provided with a first electrical contact 211, a second electrical contact 212, and a third electrical contact 213. The first electrical contact 211, the second electrical contact 212, and the third electrical contact 213 can all make electrical contact with the power-conducting components of the imaging device. The first electrical contact 211, the second electrical contact 212, and the third electrical contact 213 can respectively contact the DR power-conducting component, the SR power-conducting component, and the PCR power-conducting component of the imaging device to transmit power to the developing roller 220, the supply roller 300, and the charging component 400.

[0020] This processing unit connects the developing roller 220, the supply roller 300, and the charging component 400 to the same component, namely the second end cap 210. The second end cap 210 is configured as a conductive end cap, allowing the first electrical contact 211, the second electrical contact 212, and the third electrical contact 213 to be disposed on it. This enables electrical contact with the energized components of the imaging device, while simultaneously supplying power to the developing roller 220, the supply roller 300, and the charging component 400. Therefore, this processing unit can use the second end cap 210 in the developing unit 200 as an electrode, and integrate the first electrical contact 211, the second electrical contact 212, and the third electrical contact 213 onto the same component, thereby reducing the number of parts, simplifying the internal structure, and lowering costs. Power can be directly transmitted to the developing roller 220, the supply roller 300 and the charging component 400 through the second end cover 210, which can improve the power transmission efficiency. The second end cover 210 is conductive as a whole, which can greatly reduce the impact of single-line failure and improve the stability and reliability of power transmission.

[0021] Reference Figure 4 and Figure 5In some embodiments, the second end cap 210 is elastically connected to a fixing seat 230, and the end of the charging component 400 is connected to the fixing seat 230. Under elastic action, the fixing seat 230 will drive the charging component 400 to press against the photosensitive drum 120, so that the charging component 400 contacts the photosensitive drum 120, thereby transmitting power to the photosensitive drum 120. In some embodiments, a first positioning groove 215 is provided on the inner side of the second end cap 210, and the fixing seat 230 is movably connected to the first positioning groove 215. Further, guide portions 216 are provided on both sides of the first positioning groove 215, and guide grooves 233 are provided on both sides of the fixing seat 230. The guide grooves 233 are movably connected to the guide portions 216, thereby providing guidance and limiting for the movement of the fixing seat 230 in the first positioning groove 215. Further, a second positioning groove 232 is provided on the fixing seat 230, and the end of the charging component 400 is connected to the second positioning groove 232.

[0022] Furthermore, the second end cap 210 is provided with a first connecting portion 214, and the fixing seat 230 is provided with a second connecting portion 231. A first elastic member 240 is connected between the first connecting portion 214 and the second connecting portion 231. Under the action of the first elastic member 240, the fixing seat 230 will drive the charging component 400 to press against the photosensitive drum 120, so that the charging component 400 contacts the photosensitive drum 120, thereby transmitting power to the photosensitive drum 120. In some embodiments, the first connecting portion 214 and the second connecting portion 231 are both connecting protrusions, and the first elastic member 240 is a cylindrical spring. The two ends of the spring are respectively sleeved on the outer periphery of the first connecting portion 214 and the second connecting portion 231, and the two ends of the spring abut against the fixing seat 230 and the second end cap 210, respectively. After assembly, the first elastic element 240 is compressed. Under the action of elastic restoring force, the first elastic element 240 will push the fixing seat 230 towards the photosensitive drum 120, so that the charging component 400 in the fixing seat 230 keeps in contact with the photosensitive drum 120 in the photosensitive unit 100.

[0023] Reference Figure 6 and Figure 7In some embodiments, the photosensitive unit 100 further includes a photosensitive drum gear 130 and a first coupling 140. The photosensitive drum 120 is coaxially connected to the photosensitive drum gear 130, and the end of the photosensitive drum 120 is connected to the first coupling 140. The first coupling 140 is inserted into the first end cover 110. The first coupling 140 can be connected to an imaging device to receive driving force. After receiving driving force, the first coupling 140 can drive the photosensitive drum 120 and the photosensitive drum gear 130 to rotate together relative to the first end cover 110, thereby performing subsequent printing work. In some embodiments, the photosensitive unit 100 further includes a second elastic member 150. The second elastic member 150 can press against the side of the photosensitive drum 120 towards the first end cover 110, so that the photosensitive drum 120 can be reliably positioned, preventing the photosensitive drum 120 from radially moving during the printing process, thereby ensuring print quality. Furthermore, the outer side of the first end cap 110 is provided with a protrusion 111, and the second elastic member 150 includes a second sleeve portion 151 and a third extension portion 152 and a fourth extension portion 153 respectively connected to both ends of the second sleeve portion 151. The second sleeve portion 151 is sleeved on the protrusion 111, and the third extension portion 152 and the fourth extension portion 153 respectively abut against the first end cap 110, and the side of the third extension portion 152 or the fourth extension portion 153 abuts against the side of the photosensitive drum 120, thereby providing radial positioning of the photosensitive drum 120 under the action of elastic force.

[0024] Reference Figures 6 to 8 In some embodiments, the developing unit 200 further includes a drive side cover 260, a rotatable component 270, an elastic reset component 280, and a second coupling 250. The drive side cover 260 has a protrusion 263, and the second coupling 250 is inserted into the protrusion 263 of the drive side cover 260. The two ends of the developing roller 220 are respectively connected to the second end cover 210 and the drive side cover 260. The second coupling 250 can be connected to the imaging device to receive driving force. When the second coupling 250 receives driving force, it can generate torque on the drive side cover 260, causing the developing roller 220 to move toward the photosensitive drum 120. Further, the rotatable component 270 is rotatably connected to the drive side cover 260. The rotatable component 270 includes a gear portion 271 and a toothed portion 272. The radius of the rotatable component 270 at the toothed portion 272 is smaller than the radius at the gear portion 271. The outer surface of the toothed portion 272 is an inwardly concave arc-shaped surface.

[0025] When the processing cartridge is not in operation, the gear section 271 engages with the photosensitive drum gear 130, separating the photosensitive drum 120 from the developing roller 220. This prevents prolonged contact between the photosensitive drum 120 and the developing roller 220 during non-operational periods, avoiding contamination of the photosensitive drum 120 and affecting print quality. When the processing cartridge needs to be in operation, the drive side cover 260 drives the developing roller 220 towards the photosensitive drum 120, and the photosensitive drum gear 130 engages with the gear section 271 until it connects with the toothed section 272. Under the drive of the drive side cover 260, the developing roller 220 presses against the photosensitive drum 120, and the drive side... The driving force provided by the cover 260 to the developing roller 220 is greater than the resetting force of the elastic reset member 280, thereby keeping the developing roller 220 in contact with the photosensitive drum 120. Subsequently, when the photosensitive drum gear 130 continues to rotate, the rotatable part 270 will no longer continue to rotate because the toothed part 272 is connected to the photosensitive drum gear 130. When the processing cartridge needs to be in a non-working state again, the drive side cover 260 is not driven. At this time, the resetting force of the elastic reset member 280 can reset the rotatable part 270, so that the gear part 271 re-engages with the photosensitive drum gear 130, thereby separating the photosensitive drum 120 from the developing roller 220 again. Compared to using a separate separator to achieve separation and contact between the developing roller and the photosensitive drum, this processing cartridge uses a rotatable component 270 to achieve separation and contact between the developing roller 220 and the photosensitive drum 120. This simplifies the internal structure, reduces costs, and the rotatable component 270 is less prone to damage and has a longer service life. It also ensures separation and contact between the developing roller 220 and the photosensitive drum 120, improving the reliability of the processing cartridge and the printing quality of the imaging equipment.

[0026] In some embodiments, the drive side cover 260 has a third connecting portion 261 and a fourth connecting portion 262, the rotatable component 270 has a fifth connecting portion 273, the rotatable component 270 is rotatably sleeved on the third connecting portion 261, and the elastic reset component 280 includes a first sleeve portion 281 and a first extension portion 282 and a second extension portion 283 respectively connected to both ends of the first sleeve portion 281. The first sleeve portion 281 is sleeved on the third connecting portion 261, and the first extension portion 282 and the second extension portion 283 are respectively fixedly connected to the fourth connecting portion 262 and the fifth connecting portion 273. When the processing cartridge is in the working state, the photosensitive drum gear 130 rotates, which in turn drives the rotatable component 270 to rotate. At this time, the elastic reset member 280 is subjected to tensile force or compressive torque. When the processing cartridge changes from the working state to the non-working state, neither the first coupling 140 nor the second coupling 250 is driven by any force. At this time, the elastic restoring force of the elastic reset member 280 can cause the rotatable component 270 to rotate in the opposite direction, thereby causing the gear part 271 to re-mesh and connect with the photosensitive drum gear 130, and causing the photosensitive drum 120 to separate from the developing roller 220.

[0027] In some embodiments, the third connecting portion 261, the fourth connecting portion 262, and the fifth connecting portion 273 are all connecting protrusions. The end of the third connecting portion 261 furthest from the drive side cover 260 is also provided with a latch 2613 to prevent the first sleeve portion 281 from disengaging from the third connecting portion 261. In some embodiments, the third connecting portion 261 includes a main body portion 2611 and an elastic portion 2612, which are separate from each other. The first ends of both the main body portion 2611 and the elastic portion 2612 are fixedly connected to the drive side cover 260. This can be achieved by integral molding or by other connection methods. The buckle 2613 is located at the second end of the elastic portion 2612. When the rotatable component 270 and the first sleeve portion 281 are both sleeved on the main body portion 2611 and the elastic portion 2612, the elastic portion 2612 can undergo elastic deformation relative to the main body portion 2611, and generate radial tension on the rotatable component 270 and the first sleeve portion 281 due to the elastic restoring force, thereby providing a limit for the rotatable component 270 and the first sleeve portion 281.

[0028] Example 2 Reference Figure 9 In this embodiment, the power-conducting component 500 of the imaging device is disposed within the photosensitive unit 100. The power-conducting component 500 includes a first conductive component 510 and a second conductive component 520, which are electrically connected. They can be an integral design or a separate design. The first conductive component 510 is disposed on the side of the photosensitive drum 120 and contacts the photosensitive drum 120, thereby transmitting power to the photosensitive drum 120. It can be a conductive block or a brush structure. The second conductive component 520 is disposed at the end of the first conductive component 510 and is electrically connected to a first electrical contact 211, a second electrical contact 212, or a third electrical contact 213, thereby transmitting power to the second end cap 210. For example, in... Figure 9 In this embodiment, the second conductive component 520 is electrically connected to the third electrical contact 213. In other embodiments, the second conductive component 520 may also be electrically connected to the first electrical contact 211 or the second electrical contact 212, as long as it can transmit power to the second end cap 210.
