[0034] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] Reference Figures 1 to 7 This application provides a developing roller detection device, including a base 1, a feeding section 2, a pressing section 3, and a detection section 4. The base 1 is characterized by having a stepped seat 11 and a damping rail 12; the feeding section 2 includes a material shell 21, a rotating roller 23 driven by a first motor 25, and a material belt 24 surrounding the rotating roller, on which several developing roller assemblies 7 are placed; the pressing section 3 includes a support seat 31 slidably connected to the damping rail 12, an electric push rod 33 mounted on the support seat 31, a folding plate 34 driven by the push rod 33, and a damping roller 36 driven by a second motor 35, used to clamp and rotate the developing roller assemblies 7; a detection host 5 and a controller 6 are sequentially installed on the side of the stepped seat 11; and the detection section 4 is located in the movable groove 13 of the base 1 and is used to detect the outer diameter of the developing roller assemblies 7.

[0036] The developing roller is continuously fed by the first motor 25 via the belt 24, replacing manual operation and improving efficiency. The electric push rod 33 of the aforementioned pressing and rotating unit 3, in conjunction with the second motor 35, precisely clamps and rotates the developing roller assembly 7, ensuring uniform contact with the inspection unit and reducing errors. The base 1 and damping rail 12 provide integrated support for all components. The inspection unit 4, controller 6, and inspection host 5 collaboratively process data, improving inspection continuity. The automatic feeding of the developing roller via the belt, linked to the pressing and rotating unit, significantly reduces the need for manual intervention, making it suitable for large-scale inspection scenarios. The modular design simplifies the equipment structure and reduces manufacturing costs.

[0037] Furthermore, the upper surface of the front seat of the stepped base 11 is provided with a movable groove 13, and a mounting position 14 is provided on the right side of the movable groove 13; the detection unit 4 adjusts its detection position through the movable groove 13. The left side of the frame plate 22 is fixedly connected to the first motor 25, and the lower rotating roller 23 is directly driven by the first motor. The pressure rotating parts 3 on both sides of the damping rail 12 are symmetrically arranged to apply pressure to both ends of the developing roller assembly 7 simultaneously. This optimizes positioning stability, improves transmission efficiency and balances clamping force, further ensuring detection accuracy.

[0038] As an example, such as Figures 1 to 7As shown, a developing roller inspection device includes a base 1, a feeding section 2, a pressing section 3, an inspection section 4, and a developing roller assembly 7. The base 1 includes a stepped seat 11. A damping rail 12 is fixedly connected to the upper end face of the front seat of the stepped seat 11. A movable groove 13 is opened at the front of the stepped seat 11, and an installation position 14 is opened on the right side of the movable groove 13. An inspection host 5 and a controller 6 are installed sequentially on the left side of the stepped seat 11. The feeding section 2 includes a material shell 21 fixed to the upper side of the rear seat of the stepped seat 11. A frame plate 22 is fixedly connected to the rear side of the material shell 21. Rollers 23 are rotatably connected to the upper and lower rotating openings of the frame plate 22. A material belt 24 is sleeved on both sides of the outer side of a set of rollers 23, and the material belt 24 is sleeved on the outer side of the middle plate of the material shell 21. Several... The dry developing roller assembly 7 has a first motor 25 fixedly connected to the left side of the frame plate 22. The output shaft end of the first motor 25 is fixedly connected to the lower rotating roller 23. Both sides of the damping rail 12 are equipped with pressing parts 3. The pressing parts 3 include a support base 31 that is slidably connected to the damping rail 12. A guide plate 32 is fixedly connected to the rear side of the support base 31. An electric push rod 33 is installed on the side of the support base 31 away from the movable groove 13. A folding plate 34 is fixedly connected to the upper end of the electric push rod 33. A second motor 35 is fixedly connected to the side of the folding plate 34 away from the movable groove 13. The output shaft end of the second motor 35 passes through the folding plate 34 and is fixedly connected to a damping roller 36. The damping roller 36 and the positioning port of the support base 31 are aligned vertically. A detection part 4 is installed at the movable groove 13.

[0039] The detection unit 4 includes an electric telescopic rod 41 fixed inside the mounting position 14. The left end of the drive rod of the electric telescopic rod 41 is fixedly connected to a support plate 42 located inside the movable groove 13. A laser emitter 43 and a laser receiver 44 are sequentially installed on the front and rear sides of the upper end of the support plate 42, respectively. Both the laser emitter 43 and the laser receiver 44 are positioned on the front and rear sides of the damping rail 12. The laser emitter 43 and the laser receiver 44 are electrically connected to the detection host 5. The detection unit 4 can detect the outer diameter of the rotating developing roller assembly 7, and the detected data can be transmitted to the detection host 5 for processing and result generation. The electric push rod 33, the electric telescopic rod 41, the first motor 25, and the second motor 35 are all electrically connected to the controller 6. This configuration allows the controller 6 to control various electrical devices. The damping roller 36 consists of a rod and a damping sleeve. The diameter of the damping roller 36 is related to the fixed position of the support base 31. The width of the slots is the same, which ensures that the downward movement of the damping roller 36 can reliably position the developing roller assembly 7 and drive the developing roller assembly 7 to rotate after rotation. Several equally spaced annular grooves are opened on both sides of the rotating roller 23. This allows the material belt 24 to be repositioned to accommodate developing roller assemblies 7 of different lengths. The material belt 24 consists of a damping ring belt and several support strips fixed to the outside of the damping ring belt. The damping ring belt of the material belt 24 is set inside the annular groove of the rotating roller 23. This ensures that the material belt 24 will not slip off from the rotating roller 23. The guide plate 32 is a vertical plate structure with a multi-sloped inclined surface at the top. The guide plate 32 is set below the connecting rods at both ends of the developing roller assembly 7. The laser emitter 43 is set below the guide plate 32. This allows the guide plate 32 to guide the developing roller assembly 7 to the support seat 31, while the laser emitter 43 will not cause interference.

[0040] The outer diameter detection operation for the developing roller assembly 7 is as follows. Note that all electrical equipment in this solution is externally powered. The damping ring of the material belt 24 has a certain degree of extensibility, facilitating the repositioning of the material belt 24 to accommodate developing roller assemblies 7 of different lengths. First, multiple developing roller assemblies 7 are placed on the front support strip of a set of material belts 24. When feeding is required, the controller 6 starts the first motor 25, causing the rotating roller 23 to rotate a fixed number of revolutions, which in turn causes the set of material belts 24 to move a fixed distance. This displacement of the material belt 24 causes multiple developing roller assemblies 7 to move downwards simultaneously. During this downward movement, the lowest developing roller assembly 7 will contact the guide plates 32 on both sides, causing it to detach from the material belt 24 and move towards the support base 31 under the guidance of the guide plates 32. Finally, the two connecting rods of the developing roller assembly 7 will fall into the positioning openings of the support base 31, thus completing the automatic feeding. Afterwards, each feeding only requires the controller 6 to control the first motor 25 to move a fixed quantity. The device automatically feeds the developing roller assembly 7 by rotating the control rod 33. After feeding, the controller 6 controls the electric push rod 33 to retract and the second motor 35 to run. The retraction of the electric push rod 33 drives the damping roller 36 to move down through the folding plate 34 and into the positioning port of the support base 31 to press down and position the connecting rod of the developing roller assembly 7. The operation of the second motor 35 drives the damping roller 36 to rotate, which in turn causes the developing roller assembly 7 to rotate. At this time, the electric telescopic rod 41 is controlled to reciprocate, driving the support plate 42, laser emitter 43 and laser receiver 44 to reciprocate to the sides of the rotating developing roller assembly 7. The outer diameter of the developing roller assembly 7 is detected by laser. The detected data is processed by the detection host 5 to generate a chart to determine whether there is a problem with the developing roller assembly 7. After the detection is completed, the operator only needs to remove the developing roller assembly 7. This device can automatically feed the developing roller assembly 7, making it easier for operators to detect a large number of developing roller assemblies 7.
