Abstract
The invention discloses a low-current pneumatic knife switch comprising a first bracket, a second bracket, a base, a knife holder, a knife blade, an electric control box, and an air pipe. The first bracket and the second bracket are respectively mounted at the left and right ends of the upper part of the base. The knife holder is mounted at an upper port of the first bracket. The knife blade is transversely mounted between the second bracket and the knife holder. The electric control box is mounted at the bottom of the base. The air pipe is mounted at the bottom of the base, and is disposed at one lateral side of the electric control box. Through the scheme, the low-current pneumatic knife switch provided by the invention is simple in structure and convenient to use. Under control of low current of the electric control box, an input air source signal is converted into required pressure to make the knife blade opened to a corresponding position. Knife blade positioning can be controlled accurately. The low-current pneumatic knife switch has a high degree of automation.
