① The range of packaging specifications should not be too different as far as possible. The larger the range difference is, the greater the accuracy error will be. Range range refers to the distance between small quantitative point and large quantitative point. The scientific range is that the small range is greater than or equal to 10% of the large range, that is, the large range point is 10 times of the small range. Relatively speaking, 1. Automatic quantitative packaging scale without bucket The hopper less automatic quantitative packaging scale is also known as gross weight scale and auger scale. Its weighing and quantitative control process is relatively simple. The packaged items are directly put into the container or packaging bag for weighing, and the quantitative control process is achieved by controlling the size of the opening of the discharge door. The fixed value filling of liquid mostly adopts this form. Features: simple structure, high precision Select a weighing module to form a scale body with the scale platform, or directly select a platform scale, and then connect a weighing instrument and some simple control buttons to form a gross weight type quantitative control device. 2. Automatic quantitative packaging scale with bucket The bucket automatic quantitative packaging scale is also known as the net weight scale. Its control process is to complete the quantitative feeding process through an intermediate measuring bucket. At the beginning, the feeding door of the measuring bucket is closed, and the upper feeding port is opened for constant value feeding. When the target value is reached, the feeding port is closed, and the opening port is opened to put the material into the container or package, and then enter the next control cycle.
