[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a rivet production equipment with screening function, comprising: a screening box 1, a drive rod 2 rotatably installed inside the screening box 1, a push rod 3 rotatably installed at one end of the drive rod 2, an opening and closing plate 4 rotatably connected to the bottom of the push rod 3, two opening and closing plates 4 are provided, one of which has a first pressure sensor 5 fixedly installed on one side, and the other has a second pressure sensor 6 fixedly installed on one side, a push plate 7 is provided on one side of the first pressure sensor 5 and the second pressure sensor 6, and a drive mechanism 8 is provided on one side of the push plate 7.

[0022] By placing the finished rivets into the screening box 1, they fall onto the opening and closing plates 4, thus contacting the first pressure sensor 5 and the second pressure sensor 6 on both sides of the opening and closing plates 4. The first pressure sensor 5 and the second pressure sensor 6 measure the weight of the rivets. The weight of the rivets is checked based on the sum of the weight values ​​of the first pressure sensor 5 and the second pressure sensor 6. When the weight of the rivets meets the standard, the rotation of the drive rod 2 drives the other rotatably connected push rod 3 to push downward, causing the push rod 3 to open the two opening and closing plates 4, allowing the rivets to fall vertically for collection. Afterward, the opening and closing plates 4 return to their original positions. When the weight of the rivets does not meet the standard, the drive mechanism 8 indirectly drives the push plate 7 to move laterally, causing the push plate 7 to push the rivets laterally and push them out from the side of the screening box 1 for collection. Afterward, the push plate 7 returns to its original position. This provides the advantage of easy screening and solves the problem that the production equipment cannot effectively screen rivets that do not meet the quality standards. This solves the problem that users need to inspect all rivets one by one after all rivets have been processed, which reduces the practicality of the production equipment.

[0023] Example 2: Based on Example 1, the drive mechanism 8 includes a small motor 9, which is fixedly installed on one side wall of the screening box 1. A feed pipe 10 is fixedly fitted onto the other side wall of the screening box 1. An observation window 11 is provided on the upper side of the small motor 9 and is fixedly installed on the screening box 1. The small motor 9 is fixedly installed on the side wall of the screening box 1 and is electrically connected to the control processor 17. The feed pipe 10 fixedly fitted onto the screening box 1 facilitates connection with the rivet processing equipment, thereby guiding the finished rivets into the screening box 1. The observation window 11 is made of transparent glass, allowing personnel to observe the screening process. The output end of the small motor 9 is fixedly connected to one end of a threaded rod 12, and the other end of the threaded rod 12 is rotatably fitted onto... On the side wall of the screening box 1, a limiting rod 13 is provided on one side of the threaded rod 12. Both ends of the limiting rod 13 are fixedly sleeved on the side wall of the screening box 1. Connecting blocks 14 are sleeved on both the threaded rod 12 and the limiting rod 13. The threaded rod 12 and the connecting block 14 are threadedly connected, and the limiting rod 13 and the connecting block 14 are slidably sleeved. Both ends of the pusher plate 7 are fixedly connected to the connecting block 14. One side of the connecting block 14 is fixedly connected to the side wall of the pusher plate 7, so as to facilitate the pusher plate 7 to push the material. A qualified box 15 is provided at the bottom of the connecting block 14. A defective box 16 is fixedly connected to one side of the qualified box 15. A control processor 17 is provided on one side of the top of the qualified box 15. The control processor 17 is fixedly installed on the outer side wall of the screening box 1. A guide plate 22 is fixedly connected to one side of the upper surface of the defective box 16.

[0024] When the first pressure sensor 5 and the second pressure sensor 6 determine that the produced rivets are unqualified, the control processor 17 will control the small motor 9 to drive it. The small motor 9 will drive the threaded rod 12 to rotate. The connecting block 14 on one side is threadedly engaged with the threaded rod 12, thereby driving the connecting block 14 on one side to move, which in turn drives the pusher plate 7 to move. This causes the connecting block 14 on the other side to slide under the limit of the limit rod 13, causing the pusher plate 7 to move closer to the opening of the side wall of the screening box 1. The pusher plate 7 pushes the rivets out of the screening box 1. Under the guidance of the guide plate 22, the unqualified rivets fall into the defective box 16, thereby collecting the unqualified rivets. Then, the small motor 9 is driven in reverse to reset the pusher plate 7, which is then convenient for the next screening.

[0025] Example 3: Based on Example 2, a large motor 18 is provided on one side of the control processor 17. The large motor 18 is fixedly installed on the top of the inner side wall of the screening box 1. The output end of the large motor 18 is fixedly connected to one end of the drive rod 2. The other end of the drive rod 2 is rotatably connected to one end of the push rod 3 through the connecting pin 19. The first pressure sensor 5 and the second pressure sensor 6 are both electrically connected to the control processor 17. The control processor 17 is also electrically connected to the large motor 18 and the small motor 9. The large motor 18 is fixedly installed on the top side wall of the screening box 1, and its output end is fixedly connected to one end of the drive rod 2, thereby facilitating the rotation of the drive rod 2. The other end of the push rod 3 is rotatably connected to the connecting seat 20 through the connecting pin 19. The connecting seat 20 is fixedly installed on one side of the upper surface of the opening and closing plate 4. The two ends of the opening and closing plate 4 are rotatably connected to the screening box 1 through the limiting pin 21.

[0026] The feed pipe 10 is connected to the rivet processing equipment, allowing the processed rivets to enter the screening box 1 through the guide limit of the feed pipe 10. The rivets then come into contact with the first pressure sensor 5 and the second pressure sensor 6. The weight of the rivets is calculated by the first and second pressure sensors 5 and 6, and the sum of the values ​​from the first and second pressure sensors 5 and 6 is transmitted to the control processor 17. Based on whether the rivet weight is qualified, the control processor 17 starts the large motor 18. The large motor 18 drives the drive rod 2, which is fixedly connected to its output end, to rotate. The drive rod 2, through the rotating connection of the connecting pin 19, drives the push rod 3 downward. The push rod 3, through the rotating connection of the connecting pin 19 and the connecting seat 20, causes the opening and closing plate 4 to rotate outward around the limiting pin 21, thus opening the gap between the two opening and closing plates 4. This allows the qualified rivets to fall into the qualified box 15 for collection. Then, the large motor 18 is driven in reverse to reset the opening and closing plate 4.
