. (1) This machine adopts computer metering device, accurately weighed, sexual stable, easy to operate; (2) body all sealed and equipped with a dust port, reasonable structure, durable truly environmentally friendly production; (3) volume small size, light weight, easy adjustment and maintenance; (4) mechanical and electrical integration, save energy, it can automatically achieve the compaction of bags, release the brake loose off and swap bags and other functions. Pneumatic components of the aircraft using the air compressor, solenoid valve and cylinder, achieved through the integration of mechanical, electrical, gas bags pressed, release, automatically closing a gray bag full off bags and other automation functions. The product design is novel, unique structure, stable performance, good sealing, bagging capacity, high degree of automation, simple operation, low maintenance costs, the production process only artificial pocket, weighing mechanism and bagging the number of microcomputer control, accurate measurement the ash mouth leak ash phenomenon bag focusing feed normal circumstances ensure that manufacturers can meet the demand.
