[Chinese Packaging Network News] The benefits and principles of the quantitative packaging scale, structure
importance
Packaging Scales In the tendering of the state-owned food reserve warehouse organized by the State Grain Administration, many units have ordered quantitative packing scales. Its performance and proficiency in use directly affect the economic benefits of the national grain reserves. Under this background, it is very urgent and necessary for the grain reserves to be proficient in the necessary debugging knowledge. From the above, we can see that the packaging scale is an important food packaging equipment, and it is also very important for the country’s grain reserve warehouse equipment. The use of the quantitative packaging scale has been well reflected, and production and benefits have also been obtained. With great improvement, the quantitative packaging scale has further promoted the economic benefits of the food packaging industry.
Basic working principle
When the quantitative packing scale enters the automatic running state, the weighing control system opens the feeding door and starts feeding. The feeding device is a fast and slow feeding mode; when the material weight reaches the fast feeding set value, the fast feeding is stopped. Material, keep slow feeding; When the weight of the material reaches the final set value, close the feed door to complete the dynamic weighing process; at this time the system detects whether the bag clamping device is in the predetermined state, when the packaging bag is clamped, the system issues The control signal opens the weighing hopper discharge door, and the material enters the packaging bag. After the material is discharged, the hopper discharge door is automatically closed. After unloading the material, the bagging device is released and the packaging bag is automatically dropped; after the packaging bag is dropped, the bag is dropped. Sew and transport to the next station. This cycle runs automatically.
structure
Quantitative packing scale consists of weighing unit, trolley, sewing package conveying device, pneumatic system, dust removal system, and quantitative packaging control instrument. Among the key components that affect the speed and accuracy of the packaging are the weighing cells, which include storage bins, gates, cutting devices, scale bodies, bagging devices, brackets, and electrical control devices. The storage silo is a buffer silo, used for material storage and provides a nearly uniform material flow; the gate is located at the bottom of the storage silo, and is used to block the materials in the storage silo when the equipment is overhauled or fails; The feeding device consists of cutting hoppers, cutting doors, pneumatic components, replenishing valves, etc. It provides fast and slow two-stage feeding during the weighing process. The material flow of fast and slow feeding can be individually adjusted to ensure quantitative The packing scale meets the accuracy requirements and speed requirements for metering; the role of the compensating valve is to balance the air pressure difference in the system; the scale body is mainly composed of a weighing bucket, a load-bearing bracket and a weighing sensor, and the weight is completed to the electrical signal. Transformation and transmission to the control unit; the bagging device is mainly composed of a bagging mechanism, pneumatic components, etc. The role is to clamp the packaging bag so that the weighed materials all fall into the packaging bag; the electrical control device consists of a weighing display controller, Electrical components and control cabinets are used to control the system and make the entire system work in an orderly manner.
The above is about some of the relevant understanding of the quantitative packaging scales, to allow everyone to have a certain understanding and definition of packaging equipment, in some of the more unconventional for the packaging scales, there are some help.
