Obviously, the accompanying drawings described below are only one embodiment of the utility model. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on this drawing and embodiment, which all belong to the protection scope of the utility model.

[0018] according to Figure 1-4As shown, a valve plate structure of a flow regulating valve includes a hopper 1, a first valve plate 6 is rotatably installed in the middle of the hopper 1, a second valve plate 7 and a third valve plate 8 are respectively provided on the left and right sides of the first valve plate 6, the second valve plate 7 and the third valve plate 8 are both rotatably installed on the hopper 1, the first valve plate 6, the second valve plate 7, and the third valve plate 8 are interconnected by a sprocket transmission assembly, and a driving mechanism is fixedly installed on the front side wall of the hopper 1.

[0019] In this embodiment, a feed port 2 is provided at the top of the hopper 1, a first discharge port 3 is provided at the bottom of the hopper 1, a second discharge port 4 is provided on the left side of the first discharge port 3, and a third discharge port 5 is provided on the right side of the first discharge port 3, and the angles between the second discharge port 4 and the third discharge port 5 and the first discharge port 3 are both 45 degrees.

[0020] In this embodiment, the first valve plate 6 is located in the middle of the first discharge port 3, the second valve plate 7 is located between the second discharge port 4 and the first discharge port 3, the bottom ends of the second valve plate 7 and the third valve plate 8 are rotatably connected to the hopper 1, and the third valve plate 8 is located between the third discharge port 5 and the first discharge port 3. A baffle plate 9 is provided above the second valve plate 7 and the third valve plate 8, and the baffle plate 9 is fixedly connected to the inner wall of the hopper 1, and the bottom end of the baffle plate 9 is inclined toward the middle of the hopper 1.

[0021] In this embodiment, the transmission assembly includes a sprocket 10, which is fixedly mounted on the rotating shafts of the first valve plate 6, the second valve plate 7 and the third valve plate 8, respectively. The sprockets 10 are interconnected by chains 11. When any group of valve plates rotates, the other valve plates will rotate synchronously with the cooperation of the sprocket 10 and the chain 11.

[0022] In this embodiment, the driving mechanism includes an electric telescopic rod 12, which is fixedly mounted on the front outer wall of the hopper 1. A connecting plate 13 is fixedly mounted on the power output end of the electric telescopic rod 12. A slider 14 is fixedly mounted on the top of the connecting plate 13. The slider 14 is slidably mounted on a guide rod 15. The guide rod 15 is fixedly mounted on the front outer wall of the hopper 1. A rack 16 is fixedly mounted on the bottom of the connecting plate 13. A gear 17 matching the rack 16 is fixedly mounted on the rotating shaft of the first valve plate 6. The connecting plate 13 is driven by the electric telescopic rod 12 to slide along the guide rod 15, and the rack 16 moves synchronously with the connecting plate 13. When the rack 16 moves, it drives the gear 17 to rotate, thereby driving the first valve plate 6 to rotate. Under the cooperation of the sprocket 10 and the chain 11, the second valve plate 7 and the third valve plate 8 rotate synchronously with the first valve plate 6.

[0023] The specific working process of the utility model is as follows: when adjusting the material flow direction, the connecting plate 13 is driven by the electric telescopic rod 12 to move along the guide rod 15. When the connecting plate 13 is in the middle position of the guide rod, the first valve plate 6, the second valve plate 7 and the third valve plate 8 are all in a vertical state. At this time, the feed port 2 is connected to the first discharge port 3. When the connecting plate 13 moves to the rightmost end of the guide rod 15, the gear 17 rotates 45 degrees clockwise under the action of the rack 16, and the first valve plate 6 rotates 45 degrees synchronously with the gear 17. The second valve plate 7 and the second valve plate 8 are in the chain. Under the action of the wheel 10 and the chain 11, it flips 45 degrees clockwise. At this time, the top end of the first valve plate 6 abuts against the baffle plate 6 on the right, and the bottom end of the first valve plate 6 abuts against the second valve plate 7. At this time, the feed port 2 is connected with the second discharge port 4. When the connecting plate 13 moves to the leftmost end of the guide rod 15, the feed port 2 is connected with the third discharge port 5. Therefore, the flow direction of the material can be adjusted by a group of driving mechanisms, thereby avoiding damage to the valve plate and other components caused by misoperation, and using an electric telescopic rod to control the angle of the valve plate can effectively reduce production costs.
