At this time, the silver contacts can be directly transmitted to the pressing bin, and the silver contacts can be supported, which is convenient for the pressing block to press the silver contacts. At the same time, under the action of the positioning mechanism 27, the pressure plate 37 on the other side will press on the surface of the silver contacts to realize the positioning of the silver contacts, and the pressure plate 37 also has the function of preparatory pressing of the silver contacts, and there is a support at the bottom of the pressing bin, and the pressed silver contacts can directly fall from the discharge chute, which is convenient for material removal.

[0025] The pressing mechanism 2 includes a driving cylinder 4, which is rotatably mounted on the surface of the L-shaped main body 1. A connecting column 6 is arranged on the top of the outer surface of the driving cylinder 4. A swing plate 5 is mounted on the other end of the connecting column 6 through a rotating shaft.

A first rack 20 is provided on the top of the first sliding plate 18, and a second rack 22 is provided on the bottom of the second sliding plate 21. The first rack 20 and the second rack 22 are both meshed with the gear 17. When the first sliding plate 18 slides toward the first conveyor belt 12, the second sliding plate 21 is meshed with the gear 17 through the first rack 20 and the second rack 22. It will slide in the direction of the second conveyor belt 13. Conversely, when the first sliding plate 18 slides in the direction of the second conveyor belt 13, the second sliding plate 21 will slide in the direction of the first conveyor belt 12. The end of the first sliding plate 18 is provided with an arc head 19. The arc heads 19 at both ends of the first sliding plate 18 respectively cooperate with the end of the first conveyor belt 12 and the end of the second conveyor belt 13. Under the action of the arc head 19, the two ends of the first sliding plate 18 can respectively cooperate with the end of the first conveyor belt 12 and the end of the second conveyor belt 13, thereby closing the bottom of the pressing bin at both ends, making it convenient for the first conveyor belt 12 and the second conveyor belt 13 to transport the silver contacts into the pressing bin.

[0028] A through slot 38 is provided on the inner wall of the material discharge chute, and the bottom of the L-shaped connecting frame 39 passes through the through slot 38 and is movably installed in the material discharge chute. The bottom of the first sliding plate 18 is fixedly connected to the L-shaped connecting frame 39. When the horizontal position of the L-shaped connecting frame 39 changes, the L-shaped connecting frame 39 can drive the first sliding plate 18 to move, so that the first sliding plate 18 will change with the change of the position of the swing plate 5, and the first sliding plate 18 will move synchronously with the swing plate 5. The top of the second sliding plate 21 is fixedly installed with a limit frame 23 by bolts, and the bottom of the limit frame 23 is movably installed on the surface of the connecting block 14 through a towing platform. Under the action of the limit frame 23, the movement of the second sliding plate 21 above the connecting block 14 can be more stable.

[0029] The positioning mechanism 27 includes a first groove 28. The inner wall of the stop surface 25 and one end close to the pressing bin is provided with a first groove 28. A contraction groove 34 is provided at the bottom of the first groove 28. A push column 31 is slidably installed inside the first groove 28. A spring 36 is provided inside the contraction groove 34. A lower pressing block 35 is installed at the top of the spring 36. A pressure plate 37 is connected between the two opposite lower pressing blocks 35. An inclined surface is provided at the end surface of the push column 31 adjacent to the lower pressing block 35. A corresponding inclined surface is provided at the top of the lower pressing block 35. The four end corners of the second sliding plate 21 are all equipped with protruding blocks 24, and the protruding blocks 24 correspond to the first grooves 28. When the protruding blocks 24 move toward the inside of the first grooves 28, the protruding blocks 24 have an inward squeezing force on the push column 31. At this time, the inclined surface of the end of the push column 31 has an squeezing effect on the inclined edge of the top of the pressing block 35, so that the pressing block 35 will move downward. At this time, the pressure plate 37 will press on the surface of the silver contact to realize the positioning of the silver contact, and the pressure plate 37 also has the function of preparatory pressing of the silver contact.

[0030] A second groove 29 is provided at the top of the first groove 28, and a guide rod 30 is provided inside the second groove 29. A stabilizing block 32 is installed on the top of the pushing column 31, and the stabilizing block 32 is movably sleeved on the surface of the guide rod 30. One end of the stabilizing block 32 away from the pressing block 35 is connected to the inner wall of the second groove 29 by a tension spring 33. When the protruding block 24 is away from the first groove 28, the tension spring 33 drives the pushing column 31 and the stabilizing block 32 to move outward. At this time, the pushing column 31 is away from the pressing block 35, so that the elastic force of the spring 36 can lift the pressing block 35 and the pressure plate 37 upward. At this time, the pressure plate 37 loses the pressing effect on the silver contacts, and the silver contacts can be directly transmitted to the pressing bin.

[0031] Working principle: First, the first conveyor belt 12 and the second conveyor belt 13 will simultaneously convey the silver contacts, and then, under the action of the swing motor 3, the driving cylinder 4 will drive the connecting column 6 to swing. During the swinging of the connecting column 6, the horizontal positions of the swing plate 5 and the L-shaped connecting frame 39 will change. When the connecting column 6 swings to the end, the horizontal height of the swing plate 5 will follow the connection column 6 to drop. At this time, the pressing block at the bottom of the swing plate 5 will be inserted into the pressing bin. Since the L-shaped connecting frame 39 can drive the first sliding plate 18 to move, the first sliding plate 18 will follow the swinging The first sliding plate 18 will change with the change of the position of the swing plate 5, and the first sliding plate 18 will move synchronously with the swing plate 5. The first sliding plate 18 can alternately cooperate with the first conveyor belt 12 and the second conveyor belt 13. Then, when the first sliding plate 18 slides toward the first conveyor belt 12, the arc head 19 at the end of the first sliding plate 18 is close to the end of the first conveyor belt 12. At this time, the silver contact can be directly transmitted by the first conveyor belt 12 to the pressing bin in front of the first conveyor belt 12. Since the first sliding plate 18 will move synchronously with the swing plate 5, the pressing block at the bottom of the swing plate 5 will be plugged into the first conveyor belt 12 in front of the pressing bin, thereby achieving the pressing operation of the silver contact inside the pressing bin in front of the first conveyor belt 12, and the second sliding plate 21 will slide in the direction of the second conveyor belt 13, and the protruding block 24 at the end of the second sliding plate 21 will move into the first groove 28, and the protruding block 24 has an inward squeezing force on the push column 31. At this time, the inclined surface of the end of the push column 31 has an squeezing effect on the inclined edge of the top of the lower pressing block 35, so that the lower pressing block 35 will move downward, and at this time the pressure plate 37 will press on the surface of the silver contact to achieve the positioning of the silver contact, and the pressure plate 37 It also has the function of preparatory pressing of the silver contacts. Then, when the first sliding plate 18 slides toward the direction of the second conveyor belt 13, the bottom of the pressing bin in front of the first conveyor belt 12 is in an open state. At this time, the silver contacts inside the pressing bin in front of the first conveyor belt 12 will fall directly from the discharge chute, completing the collection of the pressed silver contacts. And when the arc head 19 at the end of the first sliding plate 18 cooperates with the end face of the second conveyor belt 13, its working process is opposite to the above working process. The device can realize a pressing block to press the silver contacts transported by the conveyor belts on both sides, thereby improving work efficiency.
