Embossing machine capable of rapidly adjusting working stroke

The embossing machine comprises a machine body, a pressing head, a piston rod and a cylinder barrel, and further comprises a hand wheel, a capstan, a steel wire rope, a valve element, an upper pulley support and a lower pulley support, the capstan is installed in the pressing head, the steel wire rope is wound around the capstan, the hand wheel is connected with the capstan, and the hand wheel controls rotation of the capstan. And a damper is arranged on the stirrer and only rotates under the adjustment of a hand wheel. A through hole is formed in the side, facing the winch, of the upper portion of the cylinder barrel, a through hole is formed in the center of the piston rod, and the steel wire rope penetrates through the side wall and the center of the cylinder barrel and the center of the piston rod to be connected with a valve element of the second integrated block. A first pulley is arranged on the inner side of the upper portion of the cylinder barrel to reverse the steel wire rope, and a second pulley is installed on the lower pulley support to reverse the steel wire rope. When the steel wire rope pulls the valve element, the valve element blocks the oil inlet channel of the second integrated block, and the cylinder barrel stops rising. The device is convenient to adjust and accords with ergonomics, the hydraulic oil cylinder does not need to be disassembled, and downtime is shortened.
