[0026] The plurality of PIN pins are sequentially conveyed to the discharge channel 2 through the vibration disk 1 and continuously conveyed, and the PIN pins in the discharge channel 2 enter the upper end of the concave plate 511 in turn, and according to the thickness of such PIN pins, the output end of the servo motor 517 drives the forward and reverse double-screw screw 518 to rotate, and the two threaded blocks 519 outside the forward and reverse double-screw screw 518 move in the same direction, and the threaded block 519 slides stably in the inner cavity of the limit groove 521 through the limit block 520, and at the same time, the two threaded blocks 519 respectively drive the first baffle 522 to move in the same direction, and one side of the first baffle 522 drives the telescopic plate 523 to tilt and move through the pin shaft, while driving the telescopic plate 523 to extend, and the other end of the telescopic plate 523 also rotates on the outside of the pin shaft, so as to facilitate the adjustment of the two telescopic plates 523. The angle between them makes it easier for the PIN needles to stably enter the upper end of the concave plate 511 from the discharge channel 2 one by one, and at the same time, when the PIN needle passes through between the two telescopic plates 523, it is wrapped by the two first baffles 522, and the PIN needle fits between the two first baffles 522, giving the PIN needle a certain clamping force, and as the PIN needle behind is continuously transported, the PIN needle in front is pushed to move, and then the PIN needle moves stably between the two first baffles 522, and the longer PIN needle directly passes through the first screening slot 513 at the upper end of the concave plate 511 and moves to the guide plate 512, and then rolls down for collection, and the PIN needles whose size matches the first screening slot 513 and whose length is less than the first screening slot 513 fall into the second screening component 53 through the first screening slot 513, and then continue the screening operation.

[0027] The second screening assembly 53 includes an L-shaped plate 531 connected to the concave plate 511. The lower end of the L-shaped plate 531 is screwed to the support frame 3. The upper end of the L-shaped plate 531 is provided with a second screening slot 532. The length of the second screening slot 532 is shorter than the length of the first screening slot 513. The upper end of the L-shaped plate 531 is symmetrically connected to a second partition 533. The upper end of the second partition 533 is connected to the concave plate 511. The upper end of the L-shaped plate 531 is symmetrically provided with a second baffle 535. The outer side of the second baffle 535 They are all connected with connecting columns 537, one end of the connecting columns 537 is connected with connecting plates 538, one side of the connecting plates 538 is connected with positioning columns 539, one end of the positioning columns 539 passes through the side plates 515 and is connected to the first baffle 522, two sets of sliding grooves 534 are provided at the upper end of the L-shaped plate 531, and the lower end of the second baffle 535 is connected to sliders 536 that slide therewith on both sides, and a straight vibrator 4 is installed on the inner side of the support frame 3 through the mounting plate, and the upper end of the straight vibrator 4 is connected to the L-shaped plate 531.

[0028] When the two first baffles 522 move in the same direction, the two first baffles 522 respectively drive the connecting plate 538 to move in the same direction through the positioning column 539, and the two connecting plates 538 respectively drive the second baffle 535 to move in the same direction through the connecting column 537, and the second baffle 535 is stably limited and slid in the inner cavity of the slide groove 534 by the slider 536, which effectively improves the stability of the movement of the second baffle 535. Subsequently, the distance between the two second baffles 535 is the same as the distance between the two first baffles 522. When the PIN needle after the first screening passes through the first screening slot 513 and falls into the L-shaped plate 531, it is opened at the same time, and the direct vibrator 4 is opened at the same time. The direct vibrator 4 vibrates the L-shaped plate 531 and transmits part of the vibration source to the concave plate 511, so that the PIN needle at the upper end of the concave plate 511 can effectively vibrate and move, and at the same time, the PIN on the L-shaped plate 531 is The N needles are vibrated and moved, and the length of the second screening slot 532 is smaller than the length of the first screening slot 513, and the second screening slot 532 is located at the lower left of the first screening slot 513. Therefore, after the PIN needles are lightly clamped between the two first baffles 522, they are vibrated and moved, and the PIN needles move one by one to the top of the second screening slot 532. When the PIN needles are larger than the second screening slot 532, they pass directly through the second screening slot 532 and fall for collection, while those smaller than the length of the second screening slot 532 pass directly through the second screening slot 532 and fall, and are arranged under the L-shaped plate 531 through an external conveyor, and the smallest PIN needles are transported and collected by the conveyor. PIN needles of this size are unqualified products. By collecting and conveying them, they are recycled and processed, which facilitates the effective layered screening of PIN needles of different lengths, thereby effectively improving the screening effect.

[0029] Two support plates 8 are integrally connected to the left side of the upper end of the support frame 3. The upper ends of the support plates 8 are symmetrically provided with sockets 9. The upper end inner cavities of the sockets 9 are plugged with plug blocks 7. The upper ends of the plug blocks 7 are commonly connected to the collection box 6, and the inner cavity of the collection box 6 is connected to the partition plate 10.

[0030] By setting up the collection box 6 and the partition plate 10, the PIN needles that roll down from the guide plate 512 can fall to the left side of the partition plate 10, while the PIN needles that fall from the L-shaped plate 531 enter the right side of the partition plate 10, and finally are separated and collected by the collection box 6, which facilitates effective screening and collection.

[0031] Working principle: The utility model is controlled and connected with the vibration plate 1, the straight vibrator 4 and the servo motor 517 through an external controller. When in use, multiple PIN pins are sequentially conveyed to the discharge channel 2 through the vibration plate 1 and continuously conveyed, and the PIN pins in the discharge channel 2 sequentially enter the upper end of the concave plate 511, and according to the thickness of such PIN pins, the output end of the servo motor 517 drives the positive and negative double-screw screw 518 to rotate, and the two threaded blocks 519 outside the positive and negative double-screw screw 518 move in the same direction, and at the same time, the two threaded blocks 519 respectively drive the first baffle 522 to move in the same direction, and one side of the first baffle 522 drives the telescopic plate 523 to move tiltedly through the pin shaft, while driving the telescopic plate 523 is extended to facilitate adjustment of the angle between the two telescopic plates 523, so that the PIN needles can stably enter the upper end of the concave plate 511 from the discharge channel 2 one by one. At the same time, after the PIN needle passes through between the two telescopic plates 523, it is wrapped by the two first baffles 522, and the PIN needle fits between the two first baffles 522, giving the PIN needle a certain clamping force. As the rear PIN needle is continuously transported, the front PIN needle is pushed to move, and then the PIN needle moves stably between the two first baffles 522. The longer PIN needle directly passes through the first screening slot 513 at the upper end of the concave plate 511 and moves to the guide plate 512, and then rolls down for collection, and the size matches the first screening slot 513 and The PIN needle whose length is shorter than the first screening slot 513 falls to the upper end of the L-shaped plate 531 through the first screening slot 513. When the two first baffles 522 move in the same direction, the two first baffles 522 respectively drive the connecting plate 538 to move in the same direction through the positioning column 539, and the two connecting plates 538 respectively drive the second baffle 535 to move in the same direction through the connecting column 537. Then, the distance between the two second baffles 535 is the same as the distance between the two first baffles 522. By turning on the straight vibrator 4, the straight vibrator 4 vibrates the L-shaped plate 531 and transmits part of the vibration source to the concave plate 511, so that the PIN needle at the upper end of the concave plate 511 can effectively vibrate and move, and at the same time, the L-shaped plate The PIN pins on 531 are vibrated and moved, and the length of the second screening slot 532 is smaller than the length of the first screening slot 513. Therefore, after the PIN pins are lightly clamped between the two first baffles 522, they are vibrated and moved one by one to the top of the second screening slot 532. When the PIN pins are larger than the second screening slot 532, they pass through the second screening slot 532 directly and fall for collection, while the PIN pins smaller than the length of the second screening slot 532 pass through the second screening slot 532 directly and fall, and are set below the L-shaped plate 531 by an external conveyor, and the PIN pins with the smallest size are transported and collected by the conveyor. The PIN pins of this size are unqualified products and are collected and transported for recycling.It is convenient to carry out effective layered screening of PIN needles of different lengths, which effectively improves the screening effect. By providing the collection box 6 and the partition plate 10, the PIN needles that roll off the guide plate 512 can fall to the left side of the partition plate 10, while the PIN needles that fall off the L-shaped plate 531 can enter the right side of the partition plate 10. Finally, they are separated and collected by the collection box 6, which facilitates effective screening and collection.
