When screws are conveyed from the second conveyor belt 9, they fall onto the first conveyor belt 7. Through the extension and retraction of the electric telescopic rod 6, the slider 11 slides in the sliding groove 10 to adjust the position between the conveyor belts 7. When screws come off the second conveyor belt 9, they fall through the gaps between the conveyor belts 7, so that the bolts are fixed on the conveyor belts 7 for conveying. By adjusting the position between the conveyor belts 7, small screws fall down for screening.

[0029] In this embodiment, a rectangular block 3 is fixedly installed above the base plate 2. An electric telescopic rod 4 is fixedly installed on the right side of the rectangular block 3, and a cylinder 5 is fixedly installed on the right side of the electric telescopic rod 4. The rectangular block 3 is used to limit the position of the screw. The electric telescopic rod 4 is used to adjust the position of the cylinder 5 by extending and retracting, thus regulating the position of the screw. A second conveyor belt 9 is fixedly installed inside the base plate 2. Fixed posts 25 are fixedly installed on both sides of the second conveyor belt 9. An electric slide rail 13 is fixedly installed above the base plate 2. A second slider 14 is slidably installed inside the electric slide rail 13. A limiting plate 12 is fixedly installed above the second slider 14. The second conveyor belt 9 is fixed to the base plate 2 by the fixed posts 25. The screws transmitted from the conveyor frame 19 are transported by the second conveyor belt 9. The second slider 14 slides in the electric slide rail 13, so that the limiting plate 12 is fixed. The limiting plate 12 is adjusted by sliding through the position of the adjusting frame 15. The device body 1 is fixedly provided with a conveyor frame 19, and the conveyor frame 19 is fixedly provided with an electric slide rail 21. The electric slide rail 21 is slidably provided with a slider 4 20. The electric slide rail 21 is set in the conveyor frame 19. By sliding the slider 4 20 in the electric slide rail 21, the adjusting frame 15 and the adjusting frame 2 16 are adjusted according to the size of the screw. The adjusting frame 15 is fixedly provided above the slider 4 20. The adjusting frame 15 has a slide groove 23 inside. The slider 3 18 is slidably provided inside the adjusting frame 15. The connecting plate 17 is fixedly provided on the right side of the slider 3 18. The adjusting frame 2 16 is fixedly provided on the right side of the connecting plate 17. While the slider 4 20 slides in the electric slide rail 21, the slider 3 18 slides in the slide groove 23 to adjust the position of the adjusting frame 15 and the adjusting frame 2 16.

[0030] Working principle and process of a screw feeding device with screening function:

[0031] In use, a screw feeding device with a screening function involves the extension and retraction of the electric telescopic rod 6, while simultaneously sliding the slider 11 within the slide groove 10 to adjust the position of the conveyor belt 7. The slider 4 20 slides within the electric slide rail 21, and the slider 3 18 slides within the slide groove 23, allowing the adjusting frame 15 and adjusting frame 2 16 to be adjusted according to the screw size. After adjustment, the slider 2 14 slides within the electric slide rail 13, causing the limiting plate 12 to slide. The position of the limiting plate 12 is adjusted according to the position of the adjusting frame 15. Then, the screw is fed into the device body 1. When the pulse electromagnet is energized, electromagnetic force is generated, causing the device body 1 to rotate vertically. The device vibrates, and the tilted spring plate drives the main body 1 to torsionally vibrate around its vertical axis. Under the action of this combined vibration, the screw inside the main body 1 rises along the conveyor frame 19. When it rises to the top, the screw enters the second conveyor belt 9 for transmission. It is then transmitted to the first conveyor belt 7. When the screw comes off the second conveyor belt 9, it falls through the gap between the first and second conveyor belts 7, fixing the bolt on the first conveyor belt 7 for transmission. By adjusting the position between the first and second conveyor belts 7, smaller screws can fall and be screened. This design makes it more convenient to screen screws without manual screening, which is very convenient. It is also more suitable for screws of other sizes and has a wider range of applications.
