Packaging scale manufacturers tell you how packaging

When the quantitative packaging scale enters the automatic operation state, the weighing control system opens the feeding door to start feeding, and the feeding device is a fast and slow two-stage feeding method; when the weight of the material reaches the fast feeding set value, the fast feeding is stopped When the weight of the material reaches the final set value, close the feeding door to complete the dynamic weighing process. At this time, the system detects whether the bag clamping device is in a predetermined state. When the packaging bag is clamped, the system issues The control signal opens the discharge door of the weighing hopper, and the material enters the packaging bag. After the material is put in, the discharge door of the weighing hopper is automatically closed. After the material is emptied, the bag clamping device is released, and the packaging bag automatically drops; Sewing and conveying to the next station. This cycle runs automatically. ???The quantitative packaging scale is composed of a weighing unit, a trolley, a package conveying device, a pneumatic system, a dust removal system, and a quantitative packaging control instrument. The key component that affects the speed and accuracy of packing is the weighing unit, which includes a storage bin, a gate, a cutting device, a scale body, a bag clamping device, a bracket, and an electrical control device. The storage silo is a buffer silo, which is used for material storage and provides a nearly uniform material flow. The gate is located at the bottom of the storage silo. When the equipment is overhauled or malfunctions, it is used to block the material in the storage silo. The feeding device is composed of a cutting hopper, a cutting door, a pneumatic element, and a supplementary valve. It provides fast and slow feeding in the weighing process, and the material flow of the fast and slow feeding can be adjusted separately to ensure the quantitative The packaging scale meets the measurement accuracy and speed requirements; the role of the supplementary valve is to balance the air pressure difference in the system during weighing; the scale body is mainly composed of a weighing bucket, a load-bearing bracket and a load cell, which completes the weight-to-electric signal It is transformed and transmitted to the control unit. The bag clamping device is mainly composed of a bag clamping mechanism and pneumatic components. It functions to clamp the packaging bag and let all the weighed materials fall into the packaging bag. The electrical control device is controlled by the weighing display controller, It is composed of electrical components and control cabinet, which is used to control the work of the system and make the whole system work in an orderly manner according to a preset procedure.
