The feeding system divides the bulk powder granule into the same weight individual by a certain weight unit to facilitate storage, transportation and use. When the powder granular material is quantified, the packaging equipment suitable for the material can be selected according to the requirements of the type of material, packaging specifications, packaging precision, packaging speed, etc. Based on the output signal of weighing sensor, the system realizes automatic quantitative filling of materials. Its working process is divided into four stages: feeding, weighing, unloading and bagging. At the beginning of weighing, the controller controls the electromagnetic vibration Feeder coarse and fine feeding at the same time, the material is dropped into the weighing hopper, and 90% ~ 95% of the rated weight is added in a short time. When the weight of the material in the weighing hopper reaches the set value of the coarse feed, the electromagnetic vibration feeder stops operating, the fine feeder continues to feed, enters the slow feed stage, and completes the predetermined weight of 5% to 10%. When the material amount of the weighing hopper is close to the set value, the fine feeder stops and the weighing process is completed. When the discharge switch is touched, the controller controls the hopper discharge door to open, and the material falls into the packaging container, completing a filling cycle.

The feeding system is an indispensable supporting equipment for the mixer, which realizes the process of automatic conveying, storage, weighing and feeding of raw materials. According to the physical properties of raw materials, all kinds of materials are sucked to the Electronic scale by negative pressure once or many times in order, measured and temporarily stored, waiting for the mixing tank feeding signal, and then start the next batch of sub-metering action after completion. Through the man-machine interface to set the formula and measurement batch, to achieve the effect of automatic delivery and measurement. It can display the daily and monthly cumulative amount of each raw material through the man-machine interface, and has the function of abnormal alarm warning. The system can be connected with the main machine and auxiliary machine through the industrial computer to achieve automatic management function. Set production planning management, material management, quality management and other production process control in one, to achieve the integration of management and control; Improve the stability of the mixing tank system and the accuracy of feeding, thus improving the quality and uniformity of the product; Intelligent automatic control system, improve production efficiency, reduce labor intensity and loss; The whole process is closed operation, no dust pollution, improve the working environment of employees; Realized the conveying of materials in different packaging forms; Realize the automatic weighing of different kinds of materials such as powder, particle, block and liquid.
