重量選別秤の原理は何ですか?
Various electronic scales are often used in daily life, which facilitates the weighing and sorting of related items and ensures that people’s weighing work is easier and more convenient. Then what principle does the weight sorting scale adopt?
The online checkweigher is divided into three sections, namely the speed matching section, the weighing section, and the reject section. The inspected product flows into the first section of the DH series online checkweigher through the conveyor belt-the speed matching section, for sorting, and the product and For the distance in front of the product, a single product enters the second section—weighing section.
After the product is in the weighing section, the detected weight is automatically weighed and the equipment data high-speed processing system compares the measured weight with the standard weight set by the staff in advance, and distinguishes the normal weight range, light weight, and heavy weight. Species. After the product is in the weighing section, the detected weight is automatically weighed and the equipment data high-speed processing system compares the measured weight with the standard weight of the equipment prepared by the staff in advance, and distinguishes the normal weight range, light weight, and heavy weight. Species.
Products in the normal weight range flow directly through the third section of the equipment-the rejection section. After the equipment is identified, the heavier and lighter products will be prompted by the sound and light alarm device, and the unqualified product will be automatically rejected through the rejection device in the rejection section.
