Description

Technical Field

[0001] This utility model relates to the technical field of printing equipment, and in particular to a processing box. Background Technology

[0002] The processing cartridge is a core component of the printer, responsible for the crucial steps of image generation, toner transfer, and paper handling. Currently, when installing the processing cartridge in a printer, a force-applying component within the printer identifies the cartridge's separation mechanism. This mechanism applies force to the separation mechanism to drive the developing roller to contact or separate from the photosensitive drum. However, this structure is complex and costly, and the separation mechanism is prone to damage and unreliable identification, resulting in insufficient reliability. Furthermore, the transmission of the developing roller, photosensitive drum, and stirring frame within the processing cartridge relies on a dual-drive system, leading to poor compatibility of the processing cartridge. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a processing box with simple structure, low cost, stable recognition and good adaptability.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a box body and a moving rod. An end cap is provided at the end of the box body. One end of the moving rod is rotatably connected to the box body or the end cap. The other end of the moving rod is a force-receiving end. The force-receiving end rotates in a first direction when the force-applying component applies force, and rotates in a second direction when the force-applying component is released. The moving rod is used to make the box body recognized by the printer device when it rotates in the first direction.

[0005] Furthermore, the end cap has a movable hole, and the movable rod is provided with a limiting part located in the movable hole.

[0006] Furthermore, the limiting part is a first protrusion formed on the side end of the moving rod.

[0007] Furthermore, one end of the movable rod is provided with a mounting hole, the end cap is provided with a second protrusion, the end of the second protrusion is provided with a limit block, the end of the second protrusion passes through the mounting hole, and the limit block is provided corresponding to one end of the movable rod.

[0008] Furthermore, the movable rod is located between the box body and the end cap.

[0009] Furthermore, the force-receiving end rotates in the second direction under the action of its own gravity when the force-applying component disengages.

[0010] Furthermore, the housing is provided with a photosensitive drum and a developing roller. A photosensitive drum gear and a coupling are connected to the photosensitive drum, and a developing roller gear is connected to the developing roller. The photosensitive drum gear meshes with the developing roller gear.

[0011] Furthermore, the housing is equipped with a stirrer, and a stirrer gear is connected to the stirrer. A transmission gear is connected between the stirrer gear and the developing roller gear.

[0012] Furthermore, a transparent light guide is provided on the housing, which is located above the photosensitive drum. When the transparent light guide receives the laser from the printer, it guides the light to the surface of the photosensitive drum.

[0013] The beneficial effects of this utility model are: In contrast to the shortcomings of existing technologies, in this invention, when the processing box is placed in the printer, the force-applying component of the printer pushes the receiving end, causing the moving rod to rotate in the first direction, thus completing the printer's first recognition of the box. When the force-applying component disengages, the receiving end rotates in the second direction, causing the moving rod to rotate back to its initial position. Similarly, the force-applying component pushes the receiving end again, causing the printer to complete the second recognition of the box. Therefore, this invention identifies whether the processing box is installed correctly through secondary recognition of the moving rod. This recognition method has a simple structure and can improve the stability of recognition and the reliability of printing. As a result, this invention has the advantages of simple structure, low cost, stable recognition, and good adaptability. Attached Figure Description

[0019] like Figures 1 to 4 As shown, in this embodiment, the present invention includes a box body 1 and a movable rod 2. An end cap 3 is provided at one end of the box body 1. One end of the movable rod 2 is rotatably connected to the box body 1 or the end cap 3, and the other end of the movable rod 2 is a force-receiving end 5. The force-receiving end 5 rotates in a first direction when force is applied by the force-applying component 6, and rotates in a second direction when the force-applying component 6 is disengaged. The movable rod 2 is used to make the box body 1 recognized by the printer when rotating in the first direction. The first direction and the second direction are opposite; for example, if the first direction is clockwise, then the second direction is counterclockwise, and vice versa.

[0020] When ready to print, place the processing box in the printer. The force-applying component 6 of the printer pushes the receiving end 5, causing the moving rod 2 to rotate in the first direction, completing the printer's first recognition of the box 1. After recognition, the force-applying component 6 disengages from the receiving end 5, causing the moving rod 2 to rotate in the second direction and return to its initial position. Then, the force-applying component 6 makes secondary contact with the receiving end 5, causing the moving rod 2 to rotate in the first direction again, completing the printer's second recognition of the box 1. When the printer successfully completes two recognitions, printing begins. If either recognition fails, an alarm will sound, requiring the printer door to be opened, the processing box repositioned, and recognition repeated until successful before printing can proceed. In contrast to the shortcomings of existing technologies, in this invention, when the processing box is placed in the printer, the force-applying component 6 of the printer pushes the force-receiving end 5, causing the moving rod 2 to rotate in the first direction, thus completing the printer's first recognition of the box 1. When the force-applying component 6 disengages, the force-receiving end 5 rotates in the second direction, causing the moving rod 2 to rotate back to its initial position. Similarly, the force-applying component 6 pushes the force-receiving end 5 again, causing the printer to complete the second recognition of the box 1. Therefore, this invention identifies whether the processing box is installed correctly through the secondary recognition of the moving rod 2. This recognition method has a simple structure and can improve the stability of recognition and the reliability of printing, making this invention have the advantages of simple structure, low cost, stable recognition, and good adaptability.

[0021] It should be noted that when the movable lever 2 rotates to the corresponding position in the first direction, the control unit in the printer device identifies the movement of the movable lever 2. For example, identification is achieved by the movable lever 2 contacting the detection plate of the control unit when it rotates to the corresponding position in the first direction. Alternatively, a magnet is provided on the movable lever 2, and when the movable lever 2 moves to the corresponding position, the magnet approaches the sensing element (such as a reed switch) of the control unit, causing the sensing element to output an electrical signal to achieve identification. Alternatively, identification is achieved by the photoelectric sensor of the control unit, ensuring that the movable lever 2 is within the detection range of the photoelectric sensor when it rotates to the corresponding position in the first direction.

[0022] In some embodiments, the end cap 3 has a movable hole 7, and the movable rod 2 is provided with a limiting part located in the movable hole 7; the limiting part is a first protrusion 8 formed on the side end of the movable rod 2. Specifically, the movement of the limiting part in the movable hole 7 limits the travel of the movable rod 2.

[0023] In some embodiments, one end of the movable rod 2 is provided with a mounting hole 9, the end cap 3 is provided with a second protrusion 10, the end of the second protrusion 10 is provided with a limiting block 11, the end of the second protrusion 10 passes through the mounting hole 9, and the limiting block 11 is correspondingly provided with one end of the movable rod 2; the movable rod 2 is located between the box body 1 and the end cap 3.

[0024] In some embodiments, the force-receiving end 5 rotates in the second direction under its own weight when the force-applying component 6 disengages. Specifically, the force-receiving end 5 can be reset by its own weight.

[0025] In some embodiments, the cartridge 1 is provided with a photosensitive drum 12 and a developing roller 13. A photosensitive drum gear 15 and a coupling 16 are connected to the photosensitive drum 12, and a developing roller gear 17 is connected to the developing roller 13. The photosensitive drum gear 15 meshes with the developing roller gear 17. The cartridge 1 is provided with a stirrer, and a stirrer gear 18 is connected to the stirrer. A transmission gear 19 drives the stirrer gear 18 and the developing roller gear 17. Specifically, the printer is connected to the coupling 16 and drives the photosensitive drum gear 15 to rotate, which in turn drives the developing roller gear 17, the transmission gear 19, and the stirrer gear 18 to rotate together. Therefore, the processing cartridge uses a single-drive mode for transmission, making the cartridge structure simple, easy to install, and more adaptable.

[0026] It should be noted that during the above identification process, the photosensitive drum 12 and the developing roller 13 do not come into contact or separate. The photosensitive drum 12 and the developing roller 13 are always in contact, and the cartridge 1 remains stationary while the moving rod 2 is moving.

[0027] In some embodiments, a transparent light guide 20 is provided on the housing 1, located above the photosensitive drum 12. When receiving laser light from the printer, the transparent light guide 20 guides the light to the surface of the photosensitive drum 12. The transparent light guide 20 is made of transparent rubber. Specifically, when the laser light from the printer shines on the transparent light guide 20, it directs the laser light to the surface of the photosensitive drum 12, enabling the photosensitive drum 12 to function normally.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
