Weighing and counting packaging machine is an automated equipment that can weigh, count, and package items according to a preset weight range. The working process is as follows: the materials to be packaged are placed in the stock bin and sent to the conveyor through a hoister. The conveyor uses double belt counting, with large belts feeding and small belts supplementing. The counting can be accurate to single digits, and after the counting is completed, it is automatically sealed and cut. The machine uses PE film sealed on both sides, which is both economical and beautiful. After the sealing is completed, it is labeled and falls into the conveyor belt for automatic output. This machine is labor-saving, fast and efficient, and has strong versatility, suitable for various types of screws, fasteners, small hardware accessories, and other items. It has the advantages of accurate counting, beautiful packaging, stable operation, and convenient maintenance.
