Weight testing system for electrolytic manganese metal polar plate

The utility model relates to the technical field of pole plate weight testing, and discloses an electrolytic manganese metal pole plate weight testing system which comprises a top plate, and a weight testing mechanism is arranged at the bottom of the top plate. According to the utility model, the motor drives the first rotating rod to rotate to cooperate with the second rotating rod to convey the polar plate, when the infrared detection device judges that the polar plate is completely located on the weight testing mechanism, the first rotating rod and the second rotating rod stop rotating, the weighing sensor records the weight of the polar plate, and the weight detection counts the number of power-off plates every day; when the polar plate is located on the upper sides of the first rotating rod and the second rotating rod, the rod body of the telescopic rod stretches out and draws back to enable the brush to descend, the brush makes contact with the top of the polar plate, and the generated friction force en
