Weighing Feeder consists of two parts, one is the weighing part: including bin, weighing frame, screw, load weighing module, speed sensor, AC or DC driving motor and Tibetan speed machine. The second is the weighing instrument part: including weighing instrument, AC or DC speed control equipment and connecting door circuit and so on. Multi-feeding batching machine, some of the electronic weighing machines are connected to the factory's computer centralized control system for centralized control, the analog signal of the field instrumentation and computer signal transmission, connecting the intelligent field equipment and automation systems, digital, bidirectional transmission, multi-branch structure of the communication network.

Weighing and feeding system mainly displays multiple weighing sensors and weighing instruments, and outputs multi-stage control signals, users can directly access the PLC raw material system, terminal control system to realize multi-stage control and automatic control. According to the pre-determined formula, all kinds of different raw materials are mixed proportionally. In order to improve the accuracy and speed of batching, ensure the quality of products and increase the output, microcomputer control technology is adopted. Microcomputer-controlled mixing production line.

Feeding system in order to carry out metering must be adjusted spiral unit of time to discharge the amount of feed, by adjusting the rotation angle of the spiral per unit of time to change the amount of feed discharged per unit of time; the bottom of each raw material silo is installed with a feeding pipeline (pipeline caliber DN65), respectively, by the automatic valves and manual valves to control the switch, the automatic valves for each powder is installed close to the pipeline exit position, the feeding pump is responsible for the feed The feeding pump is responsible for feeding the material to the metering bin through the pipeline, and the automatic valve is installed at the feeding port of the metering bin to realize the fast and slow feeding control of the material.

Between the four supporting feet of the metering bin and the base of the support frame, a weighing module is installed, which is responsible for measuring the weight of the materials entering the metering bin, and the base of the support frame needs to be leveled for debugging; the raw materials are measured through the automatic diversion device at the bottom of the metering bin, and are automatically added to the corresponding mixing silo. After the total discharge valve in the metering warehouse, install the automatic valves to each mixing warehouse horizontally, and connect the front feed pipe of each automatic valve with pipeline, so as to ensure that there is no storage material after unloading, and the unloading pipeline to each mixing warehouse can be merged with a pipeline, so as to reduce the cost of materials used in pipelines.
