The automatic dosage system consists of an industrial computer, PLC programmable controller, powder dosage, liquid dosage, micro dosage and control system. This control system is a kind of automatic weighing system with vacuum feeding, dosing screw quantitative dosing, weighing hopper automatic weighing and dosing, and cumulative weighing at the same time. It is suitable for precise measurement of materials and automatic dosage in the production process.
020-34563445Weighing and batching equipment combines computer technology, automatic control, communication technology and weighing technology into one, with perfect control function, centralized display and operation, convenient data processing, simple installation and maintenance, and easy system expansion. In the structure of the computer centralized control system to solve the "danger of centralized" problem, to achieve "centralized management of the danger of decentralization", the system is stable and reliable to meet the use of continuous production process.
The main components of the weighing and batching machine are: raw material storage silo (silo or bag opening station) or front-end production equipment (mixer or crusher, etc.), pneumatic conveying system equipment (positive or negative pressure), conveying pipeline, end separation equipment (cyclone separator or buffer silo), quantitative feeding devices (rotary valves or screw Feeders), the end of the weighing and metering silo, discharging device and PLC human-machine interface electronic control components.
Weighing system is specially designed for conveying a precise measurement of the amount of material conveyed, which can be equipped with positive or negative pressure conveying system at the front, end, etc., depending on the time and space conditions and process requirements.
If the dosage control system is positive-pressure dense-phase (sending tank) conveying mode, the dosing device can be above the sending tank or at the top or bottom of the silo at the end of conveying. If there are more devices at the end, it is generally better to have the dosing device at the front end.
If the feeding system is a negative-pressure thin-phase (cyclone) conveying method, the dosing device can be located above the feeding point or at the bottom of the cyclone at the end of the conveying. If there are many devices at the end, it is generally preferable to have the dosing device at the front end.
Various combinations of front and rear ends are available, depending on the space available at the site. The value of the material formula can be quantized in advance, and the whole process can be automated after quantization.
The weighing bin can be for the reduction method or incremental weighing method.
The whole process is closed structure, by the dust removal system for the automatic collection of dust, the site environment is clean.
High-precision infinitely variable rotary feeder and infinitely variable speed control screw feeder realize precise control of feeding quantity.
The upper and lower parts of weighing equipment are connected by imported PU elastic telescopic tubes to ensure the accuracy of measuring precision.
The 10.1-inch man-machine interface can display the working status of the system in real time, and can store the data and print the report.
