Definition and working principle of vacuum suction feet

A vacuum suction feet is a pneumatic actuator with a sealing lip that forms a temporary sealed space upon contact with the object being absorbed. It draws or dilutes air within the sealed space, creating an internal and external pressure difference. Its names include vacuum suction nozzle, rubber suction head, leather bowl, etc.
The materials used to produce vacuum suction feet are usually rubber, plastic, and metal. The vacuum suction feet we often see are made of NR, NBR, Si, FKM, PUR, NE, SE, and many other types of rubber. Classified by shape, it can be divided into flat suction feet, elliptical suction feet, corrugated suction feet, and special shaped suction feet. Corrugated suction feet are divided into two-layer vacuum suction feet, three-layer vacuum suction feet, and multi-layer vacuum suction feet. According to the classification of thin enclosed spaces, they can be divided into pneumatic vacuum suction feet and manual vacuum suction feet.
Due to the special structure of the vacuum suction feet, the working principle of the vacuum suction feet forms a temporary enclosed space after coming into contact with an object. We use air lines or certain devices to extract or dilute air in enclosed spaces. In this way, the air pressure in the confined space is lower than the air pressure outside the atmosphere. Therefore, the pressure difference between inside and outside has emerged. The external air pressure will squeeze objects and vacuum suction feet together.
Through this method, we can see the vacuum suction feet sucking on objects. With our creativity, we connect limited space with external atmospheric pressure and separate vacuum suction feet from objects. Based on the above principle, vacuum suction feet are commonly used for transporting and fixing objects.
