Organic fertilizer packaging scale consists of weighing unit, trolley, sewn bag conveying device, pneumatic system, dust removal system, quantitative packaging control instrument, etc. The key component that affects the packing speed and accuracy is weighing unit, which includes storage bin, gate, cutting device, scale body, bag clamping device, bracket, electrical control device, etc.
The storage bin is a buffer bin for storing materials and providing almost uniform material flow; the gate is located at the bottom of the bin and is used to seal the materials in the bin during equipment maintenance or failure; the cutting device consists of a cutting hopper, cutting gate, pneumatic components, air supply valve, etc., which provides fast and slow feeding during the weighing process, and the material flow rate of fast and slow feeding can be adjusted separately to ensure that the quantitative packaging scale meets the metering accuracy and speed requirements.
The role of the air supply valve is to balance the air pressure difference in the system during weighing; the scale body is mainly composed of weighing hopper, load bearing bracket and load cell, which completes the conversion from weight to electric signal and transmits it to the control unit; the bag clamping device is mainly composed of bag clamping mechanism and pneumatic components.
It is used to clamp the bags, so that all the weighed materials fall into the bags; the electrical control unit consists of weighing display controller, electrical components and control cabinet. It is used to control the system and make the whole system work in order according to the predetermined procedure.
