A screw 11 is fixed on the fixing plate 10, and a connecting plate 12 is fixed on the side of the limiting plate 9 away from the baffle 8. A sliding hole 13 is provided on the connecting plate 12 to be slidably connected to the screw 11, and a nut 14 is threadedly connected to the screw 11. After loosening the screw 11, the sliding hole 13 can be moved on the screw 11, so that the limiting plate 9 can move in a direction close to or away from the baffle 8, thereby changing the distance between the limiting plate 9 and the baffle 8, which can adapt to the loading of products of different sizes in the vibration plate 1, and increase the applicability of the detection device;

[0022] A first blowing nozzle 4 is installed on the side of the weighing conveyor 2, and a first unloading chute 17 is provided on the side of the weighing conveyor 2 opposite to the first blowing nozzle 4. The first blowing nozzle 4 blows the unqualified balancing block toward the direction of the first unloading chute 17, so that the balancing block slides into the waste box along the first unloading chute 17; an infrared height detector 15, a projection detector 16, a second blowing nozzle 5 and a third blowing nozzle 6 are installed in sequence above the turntable 3 along the rotation direction of the turntable 3, and the sides of the turntable 3 are respectively aligned with the second blowing nozzle 5 and the third blowing nozzle 6 The second unloading chute 18 and the third unloading chute 19 are respectively provided at the positions, and the outer dimensions of the balancing block can be detected by the infrared height detector 15 and the projection detector 16. The second blowing nozzle 5 blows the balancing block with unqualified outer dimensions toward the second unloading chute 18, so that the balancing block slides along the second unloading chute 18 into the waste box, and the third blowing nozzle 6 blows the balancing block with qualified weight and outer dimensions toward the third unloading chute 19, so that the balancing block slides along the third unloading chute 19 into the collection box;

[0024] Working principle:

[0025] like Figure 1-2 As shown, when the compressor balance block detection device is in use, the balance block with detection is poured into the vibration plate 1, the vibration plate 1 automatically discharges the material, and the balance block flows into the weighing conveyor 2 through the bottom plate 7. The weighing conveyor 2 can weigh and transmit the product. When the weighing conveyor 2 detects that the weight of the balance block is unqualified, the weighing conveyor 2 will feed back the signal to the PLC controller. When the balance block is transported to the front of the first blowing nozzle 4, the PLC controller will control the blowing pump to start. The blowing pump blows the unqualified balance block to the direction of the first unloading chute 17 through the first blowing nozzle 4, so that the balance block slides along the first unloading chute 17 into the waste box;

[0026] The balancing block with qualified weight is transferred to the turntable 3 along the weighing conveyor belt 2. The balancing block rotates with the turntable 3 and passes under the infrared height detector 15 and the projection detector 16 in turn. The infrared height detector 15 and the projection detector 16 can detect the external dimensions of the balancing block. When it is detected that the external dimensions of the balancing block are unqualified, the infrared height detector 15 or the projection detector 16 will feed back a signal to the PLC controller. When the balancing block is transported to the front of the second blowing nozzle 5, the PLC controller will control the blowing pump to start. The second blowing nozzle 5 will blow the balancing block with unqualified external dimensions toward the direction of the second unloading chute 18, so that the balancing block slides along the second unloading chute 18 into the waste box;

[0027] The balancing block with qualified external dimensions will be transported to the front of the third blowing nozzle 6 along the turntable. The third blowing nozzle 6 will blow the balancing block with qualified weight and external dimensions toward the third unloading chute 19, so that the balancing block slides along the third unloading chute 19 into the collection box.
