The multihead weigher batching system is mostly used to carry out continuous batching of various raw materials. It can realize many functions. The display instrument of the control part can display data. This article will introduce you the principle knowledge of the multihead weigher batching system and multihead weigher batching. Knowledge of the characteristics of the automatic control system: the principle of the multihead weigher batching system The principle of the multihead weigher is the net weight damage according to the control plan. When the net weight is lower than the net weight limit and exceeds the net weight lower limit, the multihead weigher is in the state of loss-in-weight batching, and the net weight damage in the enterprise time is equivalent to the actual total flow of cutting material, and the actual total flow of cutting material is compared with the set total flow. Carry out a comparison to calculate the error, and immediately adjust the vibration amplitude of the vibrating feeder, so as to make the feeding amount uniform. When the raw material in the metering and verification hopper is reduced to the lower limit of net weight, the multihead weigher control panel will switch to the volumetric feeding state under the condition that the feeding rate will not change, and the output data signal of the control panel is loss-in-weight feeding. stable value under machine conditions.
Start the feeding machine and equipment of the batching system. The raw materials of the feeding machine and equipment enter the measurement and verification hopper. When the raw material of the measurement and verification hopper reaches a certain net weight, the feeding will be terminated. At this time, the measurement and verification control panel will accurately weigh and open according to the set total flow. The vibrating feeder is unloading, and the multihead weigher enters the weightless batching state again, and the weightless batching and volumetric batching are replaced. After knowing the working principle of the multihead weigher batching system, let's take a look at the characteristics of the multihead weigher batching automatic control system: The batching system uses a 24-bit high-precision A/D converter. The batching instrument panel uses a variety of EMI filtering technologies, with distinctive digital filtering and high-quality noise filtering, and can obtain a stable net weight value.
Program-controlled power switch input, power switch output. Customer program control enables the instrument panel to accept inputs and commands from other machinery and equipment, such as start and stop of machinery and equipment, and alarm input. The customer program control outputs a variety of power switch data signals for displaying various information content or triggering various auxiliary tools and equipment.
Multi-level account maintenance provides customers with different levels of changeable account maintenance. Strong anti-interference, there are noise and other interference sources around the multihead weigher, XK3120 has made sufficient consideration in the design of the scheme, and has strong anti-noise or other interference capabilities. Personalized man-machine system page, select VFD with high brightness and high fluorescent display, all Chinese and single animation reminder, can choose a variety of weighing pages, and the actual operation is convenient and fast.
After reading this article, everyone has an understanding of the principle and knowledge of the multihead weigher feeding system and its characteristics. If you want to know more about the multihead weigher, then pay attention to the Zhongshan Smart weigh website.
