The invention relates to a
powder body packing machine valve, which comprises front section air cylinders, back section air cylinders, a rubber
pipe, a valve frame and a rubber
pipe clamping rod, wherein the front section air cylinders are connected with the back section air cylinders for forming double-section air cylinders, the two identical double-section air cylinders are respectively arranged at the left side and the right side of the valve frame, the center position of the valve frame is provided with the rubber
pipe, the rubber pipe is respectively and fixedly arranged at the upper end and the lower end of the valve frame through an upper end pipe joint and a lower end pipe joint, the double-section air cylinders arranged at the left side and the right side of the valve frame are connected with the rubber pipe clamping rod through a
piston rod, the rubber pipe clamping rod moves leftwards and rightwards through being driven by the air cylinders so that the cross area of the rubber pipe is increased or decreased, meanwhile, the valve is opened or closed, and a fixed valve structure of the left double-section air cylinder and the right double-section air cylinder is formed. The double-section air cylinder can also be arranged at one side of the valve frame, an adjustable stoke air cylinder is arranged at the other side of the valve frame, and an adjustable valve structure is formed. The
powder body packing machine valve has the advantages that the packing speed is greatly accelerated, the
package weight precision is greatly improved, the service lives of each part of the rubber pipe and the valve air cylinders are prolonged, the maintenance cost is reduced, and the maintenance time is saved.
