Through the cylinder 13, whose input end is connected to the output end of the PLC controller, when the weight of the yogurt product is detected to be unqualified, the cylinder 13 works, causing the rejection plate 14 to gradually move away from the rejection frame 12, thereby removing the unqualified yogurt product from the roller conveyor.

[0026] In some embodiments, the movement direction of the rejection plate 14 is perpendicular to the conveying direction of the roller conveyor. Alternatively, a conveying roller conveyor for defective finished products can be provided on the front side of the roller support 3 to convey the defective yogurt products rejected onto the conveying roller conveyor.

[0027] The working principle of this utility model is as follows: When the photoelectric detector 6 detects that the finished product has arrived at the weighing area, it sends a signal to the PLC controller. The PLC controller triggers the weighing sensor 5 to detect the weight of the yogurt product. The weighing sensor 5 transmits the detected weight data to the PLC controller, and the PLC controller compares the data with the preset qualified weight range. If the weight is within acceptable limits, the PLC controller will control the roller conveyor to continue running and transport the finished yogurt to the next process. If the weight is not up to standard, the PLC controller will stop the roller conveyor and control the warning light 7 to flash red, while the buzzer will sound an alarm. After the staff finishes processing the yogurt product with abnormal weight and presses the weighing switch 11, the PLC controller receives a reset signal, controls the roller conveyor to resume operation, the warning light 7 returns to green, and the buzzer on the warning light stops sounding.
