The Double Cone 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 double-cone pneumatic mixing system has a very wide range of structural compatibility for quantitative packaging. For powdered and ultrafine powder materials, the feeding mechanism and auxiliary mechanisms (such as arch breaking and air extraction devices) should be selected based on the different properties and characteristics (particle size, bulk density, bulk density, etc.) of different materials. For some powdered materials with low bulk density and strong adsorption force on the silo wall.
The mixing system adopts a dedicated instrument for weighing control. The reaction pot has a very powerful function for handling the packaging process: The setting of any packaging target weight, the reaction pot automatically removes the tare weight, automatically corrects the error, and has multi-speed output control for the feeding execution mechanism. It also has the function of prohibiting the setting of sampling time, eliminating the influence of hopper vibration and material flushing on the measurement accuracy, and has the functions of over-tolerance output alarm. It is equipped with multiple communication interfaces for communication with the upper computer and corresponding operation software. It can be conveniently connected to the central control system of the complete production line.
The high-performance instrument, equipped with reliable frequency conversion (service) control technology, operates within the rigorous logic program of the programmable logic controller (PLC), making the operation process of the automatic mixing system intelligent, reliable and stable. Make manual operation very convenient. At the same time, full attention is paid to the suppression methods of gases inside the packaging bags: natural return gas channels, active suction and filtration (including suction during the metering process and suction during the sealing process), and great emphasis is placed on controlling dust pollution in the on-site operating environment.
Feeding methods: Screw feeding (horizontal and vertical), multi-position air valve, electromagnetic vibration feeding, sealed belt conveyor feeding, new type discharge valve feeding, etc.
Degassing methods: vacuum negative pressure type, return gas channel, normal pressure discharge type
Packaging speed: 300-500B/H (by net weight measurement); 200- 300/H (gross weight measurement) 60- 120B/H (for special materials)
Measurement accuracy: < = 0.2%
Optional accessories: arch-breaking device, air extraction device, heat sealing device
