The Spiral 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 spiral automatic Batching system can be divided into the feeding section and the batching section. The feeding section is mainly composed of equipment such as crushers, elevators, fans, Feeders and distributors. The batching section includes silos, feeders, Electronic scales and mixers. The main function of the ingredient section is that after the feeding equipment places various raw materials into their respective hoppers, the materials are fed into the weighing hopper in the proportion given by the formula, weighed, and then sent to the mixer for a certain period of stirring to evenly mix into feed products. The computer controls the feeding, weighing and mixing according to the proportion of the formula, and detects the signals of the weighing module in real time, makes judgments, and issues commands to each batching actuator, thereby achieving batching automation. The entire production system is equipped with a manual control auxiliary mechanism, which can be controlled to operate in either automatic or manual mode.
The microcomputer batching control system mainly includes the system hardware and software of the industrial control computer, as well as the corresponding electrical equipment for the sampling, detection, alarm and other actuating mechanisms. The various functions reflected in human-computer interaction and management are an important aspect of the performance of real-time control systems. Chinese prompts are provided in the menu mode. Operators can select and perform various operations by using function keys or cursor movement. The system provides a fixed recipe library. There are as many as 100 recipes. Operators can query, modify or specify a working formula for the stored formulas, and can also temporarily input and erase a formula. The system has dynamic display and printing functions. During the batching process, the computer can display the batching control flow chart on the CRT screen and provide dynamic indications with a cursor. It can simultaneously show the name and batching weight, etc., allowing the operator to have a clear understanding of the batching situation at a glance.
The feeding system can collect the weighing signals of each ingredient scale in real time, automatically remove tare, automatically zero and automatically correct errors. It can also select and control the feeding according to the specified formula ratio and relevant algorithms, and make judgments at any time, sending on and off signals to the corresponding feeders, electronic scale doors and mixer doors. Monitoring the operating status of controlled equipment during the batching process and promptly identifying problems is an important guarantee for safe production. The batching system can dynamically detect the status of the drive motors, limit switches and other equipment of each feeder and weighing gate. Once an error or fault is detected, it will immediately alarm.
