Before use, the base is installed in the desired position and the rod-shaped object to be detected is placed At the top of the conveyor belt, the power supply of the scanner and the motor is then turned on. At this time, the motor drives the conveyor belt to rotate through the drive column, and the conveyor belt drives several steering columns to move through the fixed block. At this time, the multiple rod-shaped objects between the steering columns will move synchronously. As the conveyor belt transmits, it will drive the gear to contact the gear rod. The gear rotates when it moves, and the gear drives the steering column to rotate synchronously through the rotating rod. At this time, the rod-shaped object is affected by the rotation of the steering column and will rotate synchronously, so that the rod-shaped object can rotate when entering the scanning area of ​​the scanner. Through the application of the above components, it is ensured that the backlight side of the rod-shaped object can also face the scanner, thereby improving the recognition efficiency of the equipment.

When the transmission belt rotates and forces the driving column away from the motor to rotate, the driving column drives the driving disk to rotate synchronously through the belt, and the driving disk drives the driving rod and the cleaning blades to rotate synchronously.
