The pneumatic mixing system feeds the material into the weighing bucket according to the specified proportion of the formula, and weighs it, and then sends it to the mixing machine for a certain time to stir and evenly mix into the finished product. All kinds of fixed formulations are input into the computer in advance, and the computer controls the feeding, weighing and mixing according to the proportion of the formula, and detects the signal of the weighing module in real time, makes a judgment, and issues orders to the executive mechanism of the batching, so as to realize the batching automation. The entire production system is equipped with manual control auxiliary mechanism, which can be controlled according to automatic or manual operation.
020-34563445The mixing system has a very wide range of structural compatibility for quantitative packaging. For powder and ultra-fine powder materials, according to the different properties of different materials (particle size, bulk density, weight, etc.) to choose the appropriate feeding mechanism and ancillary institutions (arch-breaking, pumping and other devices), for some powdery materials with low bulk density, strong adsorption on the wall of the silo. For some powdery materials with small packing density, strong adsorption on the silo wall, strong air affinity and other problems affecting the feeding speed and packing accuracy, special subsidiary organizations are adopted to perfectly solve the problem of difficult packing of special powders. The mixing system adopts the special instrument for weighing control, and the reaction pot has powerful functions for dealing with the packing process: the setting of any packing target weight, the reaction pot automatically removes the tare weight, automatically corrects the error, and the multi-speed output control feeding actuator and has the function of forbidding the setting of the sampling time to eliminate the vibration of the hopper and the influence of the rushing material on the measuring accuracy, and the function of overdifference output alarm, etc. It is equipped with a variety of communication interfaces and is equipped with corresponding corresponding communication interfaces to communicate with the upper computer. Equipped with a variety of communication interfaces with the host computer and the corresponding operating software, it can be easily connected to the complete set of production line central control system. Excellent performance of the instrument with reliable frequency conversion (service) control technology, running in the programmable logic controller (PLC) within the rigorous logic program, so that the automatic mixing system operation process becomes intelligent, reliable and stable; so that the manual operation becomes very simple. At the same time pay full attention to the bag gas suppression methods: natural gas return channel, active pumping over (including metering process pumping and sealing process pumping), pay close attention to the control of the site operating environment of the dust pollution. Feeding method: Screw feeding (horizontal and vertical), multi-position air valve, electromagnetic vibration feeding, sealed belt conveyor feeding, new type of discharge valve feeding and so on. Degassing method: vacuum negative pressure type Return channel normal pressure discharge type Packing speed: 300-500B/H (net weight measurement); 200---300/H (gross weight measurement); 60--120B/H (special materials) Measuring accuracy: <=0.2% Optional accessories: arch-breaking device, pumping device, heat-sealing device
