The first motor 42 drives the first conveying belt 1 to run clockwise. When the box to be processed passes through the counting sensor 15, the box to be processed is counted. Then, the box to be processed passes through the weighing sensor 11 to be weighed to obtain weight information. The box to be processed after weighing enters the cleaning chamber 12.
