The series of automatic quantitative packaging scales belong to the packaging and weighing industry. China's earliest automatic quantitative packaging scales were imported from Germany and the United States in the late 1990s. With the development of the domestic weighing industry, by the middle of the 1990s, automatic quantitative packaging had been successfully produced in China. scale business. In the 1990s, under the good situation of reform and opening up, my country's food and chemical industries have developed rapidly. During this period, the weighing instrument industry has also developed rapidly. At the same time, the automatic quantitative packaging scale industry has also experienced a leap in development speed. Therefore, automatic quantitative packaging The development of the scale industry is inseparable from the development of the weighing instrument industry.
Use weighing sensors, weighing instruments, and weighing transmitters to convert weighing signals into identifiable signals, and then use programmable ones to program the various actions we need. Reasonable use of mechanical design, machining, sheet metal technology, surface treatment and other technologies to produce actuators and form a perfect combination with the control system.
, bucketless automatic quantitative packaging scale
Bucketless 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. Weighing achieves quantitative control process by controlling the size of the discharge door. This form is often used for fixed-value filling of liquids.
Features: Simple structure, high precision
Choose to use a weighing module and a scale platform to form the scale body, or directly use a platform scale and then connect a weighing instrument and some simple control buttons to form a gross weight quantitative controlling device.
, automatic quantitative packaging scale with bucket
Automatic quantitative packaging scale with bucket, also known as net weight scale, its control process is to complete the quantitative discharging process through an intermediate measuring hopper. At the beginning of the measuring hopper, the discharging door of the measuring hopper is closed. Open the upper feeding port for fixed-value feeding. When the target value is reached, close the feeding port and open the discharging port to put the material into the container or package before entering the next control cycle.
In order to improve work efficiency, a variety of feeding speeds can be used, usually two speeds, namely fast feeding and slow feeding. High-speed fixed value control of double scale rotation can also be used.
Features: Integrated structure, high precision and fast speed. This structure is mostly used by special weighing control equipment.
Use cooperative weighing sensors or weighing modules, weighing instruments and operating buttons to form a net weight quantitative control system
