Description

Technical Field

[0001] This application relates to the field of valve seats, and more particularly to a feeding mechanism. Background Technology

[0002] The valve seat is a detachable component inside the valve, used to support the valve core in the fully closed position and form a sealing pair. After the valve seat is manufactured, a black paint layer is often applied to its surface for protection. During finishing, the black paint needs to be removed using a milling cutter. Traditionally, the material is cut manually, which is slow and results in a low pass rate for manual inspection, leading to low valve seat processing efficiency. Utility Model Content

[0003] To address the issue of increasing the efficiency of valve seat machining, this application provides a feeding mechanism.

[0004] The feeding mechanism provided in this application adopts the following technical solution:

[0005] include:

[0006] Base plate;

[0007] First conveyor belt;

[0008] Second conveyor belt;

[0009] The transfer platform, located on the base plate, is used to transfer valve seats from the first conveyor belt to the second conveyor belt;

[0010] The first conveyor belt is provided with first baffles at both ends, and guide plates are provided on the two first baffles. The two guide plates are inclined and have a gap through which the valve seat passes.

[0011] The first baffle is provided with a discharge plate for discharging defective valve seats, and the first baffle is provided with a first pusher assembly that cooperates with the discharge plate.

[0012] The first feeding assembly includes a detector mounted on a first conveyor belt, a first bracket fixed on a base plate, a first cylinder mounted on the first bracket, and a first push plate mounted on the piston rod of the first cylinder.

[0013] By adopting the above technical solution, the valve seats on the first conveyor belt pass through in an orderly manner under the action of the guide plate. When a defective product is encountered, the first cylinder is driven to move the first push plate to one side of the valve seat and push the valve seat into the discharge plate. Then the defective product is conveyed out through the discharge plate.

[0014] In one possible implementation, the first feeding assembly further includes a second cylinder mounted on the first bracket and a retention plate disposed on the piston rod of the second cylinder, the retention plate being located at the lower end of the guide plate.

[0015] In one possible implementation, a second baffle is provided on the transfer platform, and an inclined plate is provided between the transfer platform and the second conveyor belt.

[0016] In one possible implementation, the base plate is provided with a second pushing assembly for pushing the valve seat on the transfer platform onto the second conveyor belt. The second pushing assembly includes a second bracket fixed on the base plate, a third cylinder mounted on the second bracket, and a second push plate disposed on the piston rod of the third cylinder.

[0017] In one possible implementation, a support frame is provided on the base plate, a rotating shaft is rotatably mounted on the support frame, one end of the central turntable is fixedly connected to the rotating shaft, and a drive assembly for driving the rotating shaft to rotate is provided on the base plate.

[0018] In one possible implementation, the drive assembly includes a fixed plate fixedly mounted on a base plate, a fourth cylinder mounted on the fixed plate, a first connecting rod mounted on the piston rod of the fourth cylinder, a second connecting rod with one end hinged to the first connecting rod, and the other end of the second connecting rod fixedly mounted on a rotating shaft.

[0019] In one possible implementation, the base plate is further provided with a limiting block for limiting the movement direction of the second connecting rod, and the limiting block is provided with a gasket.

[0020] In one possible implementation, the support frame is provided with a fixing ring, and one end of the rotating shaft rotates through the fixing ring and connects to the central turntable.

[0021] In one possible implementation, third baffles are provided at both ends of the second conveyor belt.

[0022] In summary, this application includes the following beneficial technical effects: under the action of the guide plate, the valve seats on the first conveyor belt pass through in sequence and in an orderly manner. When a defective product is encountered, the first cylinder is driven to move the first push plate to one side of the valve seat and push the valve seat into the discharge plate. Then, the defective product is transported to the collection box through the discharge plate.

[0023] The first connecting rod is driven to move by the fourth cylinder, and the first connecting rod drives the second connecting rod to move. As the second connecting rod moves, the rotating shaft rotates at a certain angle, and the rotating shaft drives the central turntable to rotate, thereby turning the valve seat on the central turntable toward the side of the second conveyor belt.

The first conveyor belt 2 has a first baffle 5 at both ends, and a guide plate 6 is mounted on the two first baffles 5. The two guide plates 6 are inclined and have a gap between them for the valve seat to pass through. The first baffles 5 at both ends have openings 7. A discharge plate 8 is installed at one opening 7, and the first pushing assembly is located at the other opening 7. The base plate 1 has a collection box 9 that cooperates with the guide plate 6. The first pushing assembly pushes some unqualified products into the collection box 9 through the guide plate 6 for rework. The first feeding assembly includes a detector 10, a first support 11, a first cylinder 12, and a first pusher plate 13. The detector 10 is mounted on the first conveyor belt 2 and is based on existing technology. It is used to monitor whether the product is compliant. The first support 11 is fixedly mounted on the base plate 1. The first cylinder 12 is mounted on the first support 11. The first pusher plate 13 is mounted on the piston rod of the first cylinder 12. Under the action of the guide plate 6, the valve seats on the first conveyor belt 2 pass through sequentially. When a non-conforming product is encountered, the first cylinder 12 is driven to move the first pusher plate 13 to one side of the valve seat and push the valve seat onto the discharge plate 8. Then, the non-conforming product is conveyed to the collection box 9 through the discharge plate 8.

[0035] The first feeding assembly also includes a second cylinder 14 and a retaining plate 15. The second cylinder 14 is mounted on the first bracket 11, and the retaining plate 15 is located on the piston rod of the second cylinder 14. The retaining plate 15 is located at the lower end of the guide plate 6. When the valve seat passes through the guide plate 6, it will stay on the retaining plate 15. Then the detector 10 monitors whether the valve seat is qualified.

[0036] The transfer platform 4 is provided with a second baffle 16, and the two ends of the second conveyor belt 3 are provided with a third baffle 17. There is an inclined plate 18 between the transfer platform 4 and the second conveyor belt 3.

The first connecting rod 26 is driven to move by the fourth cylinder 25, which in turn drives the second connecting rod 27 to move. As the second connecting rod 27 moves, the rotating shaft 23 rotates at a certain angle, causing the intermediate transfer platform 4 to rotate, thereby turning the valve seat on the intermediate transfer platform 4 toward the side of the second conveyor belt 3. A limiting block 28 is provided on the base plate 1, and a gasket 29 is provided on the limiting block 28. Under the action of the limiting block 28, the movement direction of the second connecting rod 27 is easily limited.
