The rapid development of the automation industry has led to an increase in the demand for automatic batching systems year by year. The automatic batching system can be widely used in various industries such as food, chemical industry, feed, rubber and plastic, grain and oil, etc. In the rubber and plastic industry, it can be used in the batching process of rubber hoses and seals. In the feed industry, it can be used for automatic batching of pellets and powders. In the chemical industry, it can be used in small batches of raw materials; in the grain, oil, and food industries, it is also required for automatic batching of various raw materials. At present, the control systems used in these industries in our country are all methods of automatic batching control, so the automatic batching system has a very broad application prospect.
Today, when the manufacturing industry is highly prosperous and industrial automation is flourishing, it is often encountered the situation of controlling the ratio of various materials. In the manual control state, it is necessary to calculate the proportion of each material according to the production status, and then calculate the optimal cutting amount of each material according to the proportion, and set each equipment separately to meet the proportioning request. When the production status changes and the blanking amount needs to be changed, the set value of each material needs to be separately calculated and set again. The accounting operation time is long, and it is very easy to make mistakes, which brings adverse factors to the production. The novel method of PLC control and the method of frequency conversion speed regulation and blanking are selected, and then used with the batching control system.
The development of the times and the update of technology are affecting the direction of industrial automation development all the time. Researching the user's operating needs and operating habits has undoubtedly become the first choice for many industrial automation suppliers. The mainstream automation products are also changing under the condition that they constantly meet the needs of users: as the mainstream control products in the field of industrial control of automatic batching systems, PLC still occupies the leading position of the control system in automatic batching, and there are thousands of them in a small PLC. A user-friendly programming element allows very complex control functions to be realized. It has strong functions and high cost performance, which can be decentralized control and centralized management. Now it is moving towards the high-end industry of automation.

How to reduce the wear rate of pneumatic conveying?
2022.01.17Different from other conveying methods, pneumatic conveying relies on air energy to convey materials. In order to prevent the materials from being stagnant in the pipeline, it is necessary to keep the materials moving at a certain speed. The movement in the pipeline causes the loss of the pipeline and the destruction of the material. Generally speaking, the pipeline in the straight section is less worn, and the most easily worn part should be the elbow at the conveying reversal.
Read Details
The degree of wear is mainly affected by the following factors:
1. The nature of the conveyed material
The larger the particle size of the material, the greater the wear; the greater the specific gravity and hardness of the material, the greater the wear and tear. When the moisture content of the material increases within a certain limit, the faster the oxidation of the iron and steel material, the wear will be increased, but if the moisture content exceeds this limit, the mechanical wear will decrease, and the wear will decrease. The material is corrosive and will also wear more to the pipeline.
2. The influence of air supply
The material-to-air ratio is the ratio of the quality of the conveyed material in the pipeline per unit time to the air mass required to convey the material. The larger the ratio, the more serious the wear of the pipeline.
3. The effect of conveying air velocity on wear
The air velocity during conveying has the greatest influence on the wear of the pipe wall. If other conditions are the same, reducing the speed of the material hitting the wall or changing the impact angle of the material can greatly reduce the wall wear. Because wear is caused by the impact or friction of particles with the inner wall of the pipe. Therefore, the velocity of the particles is greater. The greater the energy of impact or friction, the greater the wear. Generally, the wear amount can be roughly considered to be proportional to the third power of the conveying air velocity. If the velocity of the air flow is too low, the conveyed material will deposit in the pipes and block the pipes. Therefore, reasonable selection of airflow speed is the key to ensure the normal operation of the system.
4. The influence of pipe diameter and pipe structure
Select the appropriate pipe diameter according to the conveying distance and conveying materials. If the pipe is too thin, not only the conveying capacity will be reduced, but also the conveying of large specific gravity materials will be slow, and the wear will increase.
The larger the radius of curvature of the long radius elbow. The more serious the impact. The more impact collision points, the greater the energy loss and the more serious the wear. also. The smoothness of the elbow is small, the greater the frictional resistance, the easier the elbow is to wear. Usually, smooth materials are selected at the elbow; if too many elbows are used, the energy consumption will be greater, the pipeline will be easily blocked and the wear of the elbow will be accelerated; the smaller the pipe diameter, the greater the resistance to the airflow, and the more serious the damage to the pipe wall.
In order to reduce wear and tear, first of all, the pipeline should be reasonably designed, the inclined section of the elbow should be minimized, and the elbow should be specially designed if necessary.

How does the automatic batching control system improve production efficiency
2022.01.17In various production fields, such as chemical industry, metallurgy, building materials, pharmaceuticals, grain, feed, food and other industries, the batching process is a very important link in the production process, which has a significant impact on the output and quality of production. The traditional industrial batching system is not completely intelligent, informatized and automated, and there are many problems:
Read Details
1. The batching speed and accuracy cannot meet the production needs;
2. Unable to meet the control requirements of various materials and ingredients;
3. Unable to meet the needs of formula change and adjustment;
4. Materials may be affected by ambient temperature and humidity;
5. The on-site production dust is large and the environment is harsh;
6. The information transmission is not timely, and the management and production are faulty.
In the face of many problems, traditional industrial batching methods have been unable to meet the production needs of enterprises, affecting the production efficiency and production quality of enterprises. The automatic and intelligent batching control system has become a problem that many production enterprises cannot wait to solve. The intelligent batching control system is guided by the customer's material characteristics, formula, and production process, and uses belts or batching spirals as conveying tools to complete the proportioning control of bulk materials and various data management in the production process according to user requirements. This system is an integrated system integrating software and hardware, basic production and management, helping enterprises to achieve the purpose of improving production efficiency, optimizing production environment, reducing costs and enhancing scientific management.
In terms of measurement control, the load cell and speed sensor have high sensitivity, and the core components are imported brands, which are less affected by the environment and have higher measurement accuracy. The measurement accuracy provides a guarantee for accurate control and production quality. The control system is realized by a high-performance programmable controller, and the upper computer can be used for formula management, screen man-machine dialogue, storage, query and printing of weighing data, etc., to realize the automation of ingredients. The weighing instrument is no longer a simple calculation and display function. It has many functions such as self-diagnosis, automatic zero tracking, dynamic weighing, data communication, etc., which improves the accuracy and strengthens the automation of batching control.
In the face of complex and changeable formulas and a variety of material ingredients, the automatic batching control system can flexibly adjust the proportion of various materials according to the customer's actual formula and production process, and the customer only needs to set the parameters on the upper computer.
In view of the changeable, harsh and dusty on-site environment, and the material may be affected by temperature and humidity, the batching control system can select the appropriate conveying and measuring equipment according to the material, such as vacuum feeder, screw feeder, and belt conveyor. A sealing structure can be added. On the one hand, it can improve and optimize the production environment, on the other hand, it can prevent the material from spilling and cause material waste, and at the same time protect the material.
The batching control system independently developed by Corey not only solves the difficult problem of batching control in on-site production, but also can be matched with the management system of the whole plant. The system metering control data is uploaded and displayed to the relevant management department in real time, and a visual data report is generated.
