Description

Technical Field

[0001] This utility model relates to the field of office equipment manufacturing technology, and in particular to a non-contact air-blowing cleaning device for photosensitive drums. Background Technology

[0002] The photosensitive drum is a core component of electrostatic imaging equipment such as printers and copiers. Its surface is covered with a photosensitive coating, which attracts toner through electrostatic attraction to form images, making it a key element determining printing accuracy. The non-contact air-blowing cleaning device is a maintenance device specifically designed for photosensitive drums. Through the coordinated action of a compressed air generator, precision nozzles, and a negative pressure adsorption device, it sprays a directional airflow onto the surface of the photosensitive drum in a non-contact manner to remove residual toner and dust. The core function of equipping the photosensitive drum with this device is to avoid the wear and scratches caused by traditional contact cleaning, while also preventing secondary contamination during the cleaning process. This ensures the lifespan of the photosensitive drum and maintains stable image quality, meeting the high-precision, long-term operation requirements of office equipment.

[0003] A contactless air-blowing cleaning device for photosensitive drums typically consists of a compressed airflow generator, a precision nozzle module, an airflow guiding structure, a negative pressure adsorption device, and a control device. The compressed airflow generator, such as a fan, provides the airflow power required for cleaning. The precision nozzle module precisely guides the airflow to the surface of the photosensitive drum. The airflow guiding structure ensures that the airflow acts on the photosensitive drum at the optimal angle and velocity. The negative pressure adsorption device collects the blown-off toner and dust, preventing secondary contamination. The control device adjusts parameters such as airflow pressure and flow rate to adapt to different cleaning needs.

[0004] In existing technologies, the air jet tubes in some non-contact air-blowing cleaning devices for photoconductor drums are fixed to the equipment and cannot be adjusted, resulting in poor cleaning effect and residual toner and dust affecting print quality. Therefore, a non-contact air-blowing cleaning device for photoconductor drums is proposed to solve the above problems. Utility Model Content

The flexible hose 7 is fixed to the top of the storage shell 8 and serves as a flexible channel for connecting gas or related components. The drive mechanism 5 includes a protective shell 51, which protects the drive components and stabilizes them. The left side of the protective shell 51 is fixedly connected to the inside of the outer shell 1. A motor 53 is fixedly connected inside the protective shell 51. The motor 53 is the drive source of the drive mechanism 5, thereby driving the subsequent components to move. A rotating rod 54 is fixedly connected to the drive end of the motor 53. The rotating rod 54 receives the rotational force from the motor 53 and rotates. A gear 55 is fixedly connected to the right side of the rotating rod 54.

The guide plate 56 allows the rack 57 to move linearly, thereby stabilizing it. The rack 57 is slidably connected inside the guide plate 56. The rack 57 moves under the action of the gear 55, thereby stabilizing it. An isolation plate 52 is fixedly connected inside the protective shell 51. The isolation plate 52 separates the drive components from the operating components. An adjustment component 58 is fixedly connected to the right side of the rack 57. The adjusting assembly 58 includes a moving rod 581, the left side of which is fixedly connected to the right side of the rack 57. The moving rod 581 receives the moving force of the rack 57 and moves accordingly. A fixed block 582 is fixedly connected to the outside of the moving rod 581 and moves with the moving rod 581. A rotating block 583 is rotatably connected inside the fixed block 582 and receives external rotational force to rotate and stabilize it. An exhaust pipe 584 is fixedly connected to the top of the rotating block 583 to allow gas to be discharged. Specifically, the protective shell 51 protects the internal components such as the motor 53, ensuring their stability. The motor 53 drives the rotating rod 54 to rotate, causing the gear 55 to mesh with the rack 57. This causes the moving rod 581 in the adjusting assembly 58 to move, which in turn causes the rack 57 to move, which in turn causes the fixed block 582 to move. This causes the rotating block 583 to rotate under the action of the hose 7, which in turn causes the air pipe 584 to rotate.

[0013] Reference Figure 2 and Figure 4 The rotating mechanism 6 includes a second motor 61, the left side of which is fixedly connected to the right side of the fixed plate 2. The second motor 61 is the driving source of the rotating mechanism 6. A rotating rod 62 is fixedly connected to the driving end of the second motor 61. The rotating rod 62 receives the rotational force from the second motor 61 and thus rotates. A fixed frame 64 is fixedly connected to the right side of the rotating rod 62. The fixed frame 64 is used to protect the photosensitive drum and can be opened. An air inlet 63 is provided on the outside of the fixed frame 64. The air inlet 63 receives the air pressure inside the outer shell 1 to clean the internal photosensitive drum.

[0014] Specifically, motor 61 drives rotating rod 62 to rotate, which in turn causes fixed frame 64 to rotate. Fixed frame 64 can be opened, allowing photosensitive drum to be inserted and cleaned under the action of air inlet 63.

[0015] Reference Figure 2 , Figure 3 and Figure 5The external rotating rod 54 is rotatably connected to the inside of the isolation plate 52. The rotating rod 54 receives the rotational force from the motor 53, thus rotating within the isolation plate 52. The external part of the gear 55 contacts the external part of the rack 57. The gear 55 receives the rotational force from the rotating rod 54 and rotates with the rack 57. The external part of the gear 55 is rotatably connected to the inside of the protective shell 51, and the external part of the rack 57 is slidably connected to the inside of the protective shell 51. The gear 55 and rack 57 rotate under the action of the rotating rod 54, thus rotating within the protective shell 51. The external rotating rod 62... The rotating rod 62 is connected to the inside of the fixed plate 2 and receives the rotational force of the motor 61 to rotate. The outside of the fixed frame 64 is rotatably connected to the adjacent side of the two fixed plates 2. The outside of the fixed frame 64 receives the rotation of the rotating rod 62 to rotate. The right side of the air supply pipe 3 is fixedly connected to the left side of the air chamber block 4. The air supply pipe 3 provides air power to the air chamber block 4, thereby supplying air and turning the air into wind blades. The top of the hose 7 is fixedly connected to the bottom of the rotating block 583. The top of the outer shell 1 is provided with a ventilation slot, which allows the wind blades inside the outer shell 1 to be released. The right side of the protective shell 51 is provided with a slot. Specifically, the first rotating rod 54 receives power from the first motor 53, causing it to rotate, which in turn causes the gear 55 to rotate, which in turn causes the rack 57 to move, which in turn causes the moving rod 581 to move, thus causing the subsequent components to move. The second rotating rod 62 receives power from the second motor 61, causing it to rotate, which in turn causes the fixed frame 64 to rotate, thus placing the photosensitive drum inside and stabilizing it.

[0016] The implementation principle of this application embodiment is as follows: First, the operator connects the air supply pipe 3 to the air chamber block 4 inside the storage shell 8, thereby allowing air to flow out of the storage shell 8 and into the air outlet pipe 584 under the action of the hose 7, thus ventilating the ventilation slot of the outer shell 1. When the operator feels that the air force is suitable, the operator first places the photosensitive drum into the fixed frame 64 of the rotating mechanism 6, and then uses the rotating mechanism 6 to rotate. At this time, the operator can use the motor 53 in the protective shell 51 of the drive mechanism 5 to drive the rotating rod 54 to rotate, thereby causing the gear 55 to rotate and contact the rack 57, thereby causing the rack 57 to move in the guide plate 56, thereby causing the moving rod 581 in the adjustment component 58 to move under the action of the rack 57, thereby causing the moving rod 581 to drive the fixed block 582 to move, thereby causing the air outlet pipe 584 connected to the hose 7 to move under the action of the rotating block 583, thereby cleaning the photosensitive drum at the top.

[0017] Secondly, after placing the photosensitive drum inside, the operator uses the motor 61 of the rotating mechanism 6 to drive the rotating rod 62 to rotate, thereby causing the rotating rod 62 to drive the fixed frame 64 containing the photosensitive drum to rotate, thus ensuring that the photosensitive drum is cleaned evenly.
