Big Bag Filling Machine is used for quantitative weighing packaging solid particulate material and powdery materials into big bags suck as 500kg, 1000kg, 2000kg, etc., and the main component parts as following: the feeding mechanism, weighing mechanism, pneumatic actuators, rail section, folder bag section, dust-removing section(optional), electric control system, etc..
Introduction of the packing machine structure:
1- Feeding device: it adopts intelligent material feeding structure, via computer transducer or reducing motor control module, to realize the fast and slow speed feeding. And, according to different materials, you could adjust the feeding speed by adjusting the transducer ( no interference ). The maximum adjustment range is 100%. Meanwhile, if also adjust the parameter setting, it could achieve the best optimal proportion of fast and slow speed feeding and ensure to increase the packing speed and keep good accuracy.
2- Bag clamping device:It adopts pneumatic clamping device, consist of annular bag clamping bucket, clamping system, executive device and bag placing signal. And the annular bag clamping bucket installed with air return way. If there's dust during filling into bag, in the outlet, it could equip trumpet shaped air suction hood and connect with the factory dust-collect system to improve the workers' working environment.
3- Weighing system:It adopts USA Sensors Systems, IL series weighing load cells which with high accuracy, durability, steady working, and impact resistance. They are matched with sole drive connection structure to fix them with the bag clamping device and weighing system.
4- Weighing control unit: It includes weighing control cabin, electromagnetic valve, proximity switch, weighing terminal with PANTHER, programmed weighing controller, isolation transformer, power supply switch and relative components. It's the brain of the packing machine working.
Working flow of the packing machine:
Work Flow: Load the materials into the hopper of packing machine. When the materials volume arrives to the height of material level, the material level indicates the packing machine to start work. Then, manually place the empty bag to the outlet body, then the weighing controller instrument will automatic deduct the self weight of the bag. Next, material level inspects that there's material in storage hopper, then the feeding system starts the fast-slow feeding procedures. When arriving to pre-set weight for fast feeding, it stops fast feeding to slow feeding. When arriving to pre-set weight for slow feeding, it stops feeding. After that, the machine will automatic check the weight if it's up to the required target weight. If it's up to standard, then unload the bag on the bag conveyor and the conveyor will transport the filled bags to the sealing machine for sealing bag top. After finishing, move the finished product for storage. The whole process is finished.
Weighing system with the metering scales electronic scales, weighing controller, with comprehensive panel digital calibration and parameter setting, with automatic tare weighing, automatic calibration, automatic error correction, alarm and fault-tolerance self-diagnostic function, high sensitivity, strong anti-interference ability.
Suitable and reasonable feeding methods, high accuracy and capacity.
Completed automatically drop off from the folder bag hooks, can be automatically transported to the next step by the free roller, powered roller or belt conveyor.
Advanced dust removal design, reduce dust pollution of the working environment.
Can be designed with shake function and/or with the flexibility to adjust the hooks height.
More flexible on-site installation, to maximize the system for the reasonable arrangements for the site, and can be customized design combined with user's requirements and the actual factory situation to make special processing to meet the conditions required.
