The automatic batching system weighs the complete feeding system by static scale and controls the discharge flow of the loose material by variable speed motor or vibrating machine. The material is removed from the system, the "weight loss" measured per unit time is compared to the desired feed (preset), and the difference between the actual (measured) flow and the desired (preset) flow is corrected by a feed controller, which automatically adjusts the feed speed to maintain accurate feed without process lag.
020-34563445The microcomputer Batching system can be divided into feeding part and batching part. The feeding part is mainly composed of crusher, elevator, fan, Feeder and distributor. The batching section includes the silo, feeder, Electronic scale and mixer. The main function of the batching part is that after the feeding equipment puts various different raw materials into their respective hopper, the material is fed into the weighing hopper according to the given proportion of the formula, and is weighed, and then sent to the mixing machine for a certain time to stir, and evenly mixed into the finished feed. 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.
The microcomputer batching control system mainly includes the system hardware and system software of the industrial computer, as well as the electrical equipment corresponding to the sampling, detection, alarm and other actuators. The function of man-machine interaction and management is an important aspect of real-time control system performance. Use the menu mode for Chinese prompts. The operator can select and perform various actions through function keys or cursor movements. The system provides a fixed recipe library. Up to 100 formulations. The operator can query, modify, or assign a working recipe to the stored recipe, and can also temporarily enter and erase a recipe. The system has dynamic display and printing functions. In the dosing process, the computer can display the dosing control flow chart on the CRT screen, and dynamically indicate with the cursor, which can display the title and the weight of the dosing at the same time, so that the operator can see the dosing situation at a glance.
The feeding system can collect the weighing signal of each ingredients in real time, can automatically peel, automatically correct and automatically correct the error, and select and control the feeding according to the specified formula proportion and relevant algorithms, and make judgments at any time, and send a switch signal to the corresponding feeder, electronic weighing door and mixing door. It is an important guarantee for safe production to detect the running state of the controlled equipment in the batching process and find the problem in time. The batching system can dynamically detect the status of each feeder, the drive motor of the weighing door, the travel switch and other equipment, and immediately alarm once errors and faults are found.
