Pneumatic Mesh-stretcher

Operation Theory
YA Series Mesh-Stretcher is composed by four completely same mechanic parts, which are connected into a rectangle stretching area. With the chain-drive and trapezium whorl silk-pole-moving structure, the machine operator can easily control the tensile strength of the stretcher by turning the plastic covered handle.

The lamination of the frame and the stretching surface is furnished by the moving of the four cylinders. The stroke of the cylinder can be used for varied thickness of frames by adjusting the spiral bolt and therefore guarantee the quality of the silk net.

Mechanic Structure
YA series Mesh-Stretcher is mainly composed by the following five parts: frame, silk pole moving structure, chain driving structure, net collets and the pneumatic system. Each part has its special features: the frame is light and firm; the silk pole moving structure is accurate and has outstanding self-lock function; the chain driving structure is light and reasonably distributed; the net collets are composed with reliable and firm double rocker which is patented by YongAn\'s only. Strong clamping force is the main reason to decide the quality of net stretching and our product is right beyond all other products at this point.
