Description

Technical Field

[0001] The utility model relates to the field of screening machines, and more specifically, to a feeding component for an optical image screening machine. Background Art

[0002] An optical image screening machine is a device that realizes automatic detection and recognition functions through visual sensing technology. The patent publication number CN220411539U discloses a feeding device for an optical screening machine, belonging to the technical field of screening machines, including a material box for an optical screening machine and a guide plate rotatably connected inside the material box. One inner wall of the material box is provided with a stepping motor, and the output end of the stepping motor is fixedly connected with a moving screw. The outer wall of the moving screw is threadedly connected with a guide block, and a support rod for supporting the guide plate is arranged on the surface of the guide block. An outlet is opened on one outer wall of the material box, and a fixed box is fixedly connected to one outer wall of the material box. Two connecting boxes are symmetrically fixed on the surface of the fixed box, and a baffle for blocking the outlet is movably connected between the two connecting boxes. This feeding device for an optical screening machine can not only adjust the feeding speed according to the feeding requirements, but also effectively prevent the outlet from discharging materials continuously.

[0003] In the existing technology, although the existing guide plate can be adjusted in angle, in the actual use process, during the material transportation, the workpieces on the top surface of the guide plate may cause the parts in contact with the surface layer to fall slowly due to accumulation, and when the inclination angle of the guide plate is relatively low, the parts on the surface layer of the guide plate are more likely to be affected by resistance and difficult to slide down, thus affecting the overall blanking speed and reducing the feeding speed of the overall device.

[0027] Embodiment 1:

[0028] Please refer to Figures 1-4 , a feeding component for an optical image screening machine, including a material box 1. A motor 2 is fixedly installed at the bottom of the inner wall of the material box 1. A screw rod 3 is fixedly sleeved on the output shaft of the motor 2. A transmission ring 4 is threadedly installed on the surface of the screw rod 3. A connecting rod 5 is rotatably installed at the top end of the transmission ring 4. A connecting rod 6 is rotatably installed inside the top end of the connecting rod 5. A guide plate 7 is fixedly installed at the top end of the connecting rod 6. At the front and rear ends on the right side of the guide plate 7, a first rotating rod 701 is fixedly installed. A groove is formed on the top surface of the guide plate 7. A limiting rod 702 and a spring 703 are respectively movably sleeved and fixedly connected inside the groove. The top ends of the limiting rod 702 and the spring 703 are fixedly installed on the same top layer plate 704. A shock-absorbing component 8 is movably installed on the inner wall of the material box 1 on the left side of the guide plate 7. The first rotating rod 701 is rotatably installed on the inner wall of the material box 1. The shape of the groove is adapted to the corresponding limiting rod 702 and spring 703.

[0029] It should be noted that the material box 1, the motor 2, the screw rod 3, the transmission ring 4, the connecting rod 5, and the connecting rod 6 described in this utility model are all existing technical means in the comparative document, so they will not be elaborated too much in this utility model.

[0030] Specifically, the limiting rod 702 can be used to limit the top layer plate 704 to reach the limiting purpose when moving upward under vibration, prevent it from detaching from the top surface of the guide plate 7 as a whole, and prevent excessive pulling force on the spring 703, thereby extending the overall service life of the spring 703. Secondly, the first rotating rod 701 can be used to limit the rotation of the guide plate 7 as a whole, so that it can achieve the purpose of rotational adjustment along a fixed center of the circle.

[0031] Please refer to Figure 4, the shock component 8 includes an arc plate 801. Both the front and rear sides of the bottom end of the arc plate 801 are fixedly installed with second rotating rods 802. The second rotating rods 802 are rotatably installed on the inner wall of the material box 1. A resilient plastic clamping plate 803 is fixedly installed on the right side surface of the arc plate 801. The number of the resilient plastic clamping plates 803 is several, and several of the resilient plastic clamping plates 803 are sequentially and equidistantly distributed on the right side surface of the arc plate 801. The top end of the outer wall on the left side of the arc plate 801 is fixedly installed with a fixing frame 804. A transfer plate 805 is rotatably installed outside the fixing frame 804. The left end of the transfer plate 805 is rotatably installed with a connecting frame 806. A stud 807 is rotatably installed inside the left side of the connecting frame 806. The stud 807 is threadedly installed inside the material box 1. The center of the arc plate 801 and the center of the first rotating rod 701 are the same point.

[0032] Specifically, the resilient plastic clamping plates 803 can intermittently apply a downward pressure to the top plate 704 during the angle adjustment process, thereby driving the spring 703 to be compressed, so that when it leaves the resilient plastic clamping plate 803, it has a greater power to lift the top plate 704, ensuring that the parts on its surface can move quickly through vibration and preventing accumulation. And when the center of the arc plate 801 and the center of the first rotating rod 701 are the same point, it is ensured that the top end of the top plate 704 does not always contact the resilient plastic clamping plate 803 during the angle adjustment, achieving the purpose of applying pressure. Finally, by rotatably connecting the connecting frame 806 and the fixing frame 804 at both ends of the transfer plate 805, it is ensured that the arc plate 801 will not have mutual movement exclusion during the contraction and storage process, affecting its rotation, and ensuring the normal operation of the overall shock component 8.

[0033] The working principle of the present utility model is as follows: When the material falls on the top surface of the top plate 704, its falling and its own gravity inertia drive the top plate 704 to move along the direction of the spring 703. At this time, the spring 703 is compressed, and then drives the top plate 704 to reset, so that the workpiece is subjected to a certain vibration and will not accumulate locally. When the guide plate 7 adjusts the angle along with the rotation of the first rotating rod 701, the top plate 704 intermittently contacts the bottom end of the resilient plastic clamping plate 803 and then passes through. The spring 703 is compressed and stretched during this process, driving the top plate 704 to continuously vibrate, quickly vibrating the material, and realizing rapid feeding. When the resilient plastic clamping plate 803 is not needed, rotate the stud 807 to drive the entire arc plate 801 to contract into the interior of the inner wall of the material box 1.

[0034] The above are only the preferred specific embodiments of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improved concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
