1. IntroductionVacuum feeding machine, also known as vacuum conveyor, is a kind of dust-free closed pipeline conveying equipment which transfers particles and powder materials by means of vacuum suction. By using the air pressure difference between vacuum and environment space, the gas flow in the pipeline is formed, which drives the movement of powder materials, so as to complete the conveying of powder. It is now widely used in chemical, pharmaceutical, food, metallurgy, building materials, agricultural and sideline industries. Vacuum transportation is a closed pipeline transportation, which can eliminate dust environmental pollution, improve the working environment, reduce the pollution of the environment and personnel to the materials, and improve the cleanliness; because of the pipeline transportation, the occupied space is small, which can complete the powder transportation in the narrow space, making the workspace beautiful and generous; especially not limited by the long and short distance. At the same time, the vacuum feeding machine can reduce the labor intensity and improve the working efficiency, which is the first choice of most powder material transportation methods. 2.

1. IntroductionBig bag unloading station is used to discharge bulk materials in big bag. According to the big bag type, there are two types of big bag unloading station. One model is bag-clamp type and another model is bag-break type. Bag-clamp type is suitable for big bag with an outlet at the bottom and bag-break type is suitable for big bag without an outlet at the bottom. Bulk bag unloading machine is widely used in food industry, chemical industry, pharmaceutical industry, plastic industry, metallurgy industry and coating industry etc. The machine can save labor intensity, increase working efficiency and improve working environment. 2. Information required for model selection①What is the big bag size? What is the weight when it is full? Does the big bag have an outlet at the bottom or not?②What is the raw material? What is the bulk density of the raw material? ③What is the fluidity of the raw material? Is it easy caking or not?④What is the allowable height for installation?⑤What is terminal equipment for material discharging?⑥Is explosion proof required for electric part? If it is, what level?

Vacuum feeding machine is a device used for conveying materials such as plastic and rubber. It attracts materials through negative pressure, sucks them from the container, and transports them to the target location, which has many advantages. Below, we will provide a detailed introduction to the characteristics of the vacuum feeding machine. 1. Efficient and energy-saving The vacuum feeding machine has the characteristics of high efficiency and energy conservation. When conveying materials, it adopts a vacuum negative pressure method, which can absorb the materials and transport them to the target position. Compared to traditional methods, vacuum feeding machines can significantly reduce material loss and waste, thereby improving work efficiency and reducing material costs. 2. Easy to operate The vacuum feeding machine is easy to operate and easy to use. Its automatic control system allows the machine to operate automatically, requiring only a small number of personnel for monitoring. Moreover, the vacuum feeding machine is compact in size and occupies a small area, so it can be moved and installed at any time. 3.Safety during operation The vacuum feeding machine is very safe during operation and will not pose any threat. Its flexible hoses and sealing materials have characteristics such as wear resistance and corrosion resistance, ensuring the long-term stable operation of the equipment. Moreover, the vacuum feeding machine also has an automatic anti blocking function, which can effectively prevent the equipment from getting stuck or interrupting operation during the operation process. 4.Wide application range The vacuum feeding machine has a wide range of applications and can be used to transport various materials such as plastic, rubber, chemical raw materials, food, etc. Its efficient and fast characteristics have made it widely used in various fields. In addition, the vacuum feeding machine can also be customized and improved according to different industries and needs to better meet user requirements. 5. Environmental protection and energy conservation The vacuum feeding machine has good environmental and energy-saving effects. It adopts a vacuum negative pressure method, which reduces air pollution and dust dispersion compared to traditional conveying methods, reduces environmental pollution, and achieves energy conservation and environmental protection in the production process. 6. Convenient maintenance The vacuum feeding machine is easy to maintain. Its structure is simple and its components are clear, so it can be repaired and maintained at any time. At the same time, the design of the vacuum feeding machine takes into account the unity and universality of the components, making it easy to find and replace parts during the maintenance process. In short, vacuum feeding machines have the characteristics of high efficiency, energy conservation, easy operation, safety and reliability, wide applicability, environmental protection, energy co...
