Disclosed is an automatic die cleaning device with reusable cleaning fluid. The automatic die cleaning device includes a robot, a cleaning fluid cyclic-spraying system and a die overturning mechanism. The automatic die cleaning device can spray the cleaning fluid to a die to clean oil stains off the surface of the wheel die, thus realizing the function of automatically cleaning the oil stains off the surface of the die; and the automatic die cleaning device also has the function of reusing the cleaning fluid, thereby saving the cleaning fluid and reducing the influence on the environment. The cleaned die surface is smooth, and the effect is ideal. The automatic die cleaning device reduces the labor intensity, meets the requirement of high-efficiency production, and improves the production efficiency.

This invention discloses a mechanical boost type cup spray-washing unit integrated with temperature-adjustment and press-control. This unit may regulate the mixing proportion of the cold water and hot water. It in combination with the boosting spray-wash effectively dissolves and washes the residues and juice on the inner wall of cup. This unit is clever in structure, integrates the temperature-adjustment and flush-washing, is directly hidden in the intermediate of the desk installation holes, never occupies surplus space of the kitchen desk, and may be installed in the standard small-hole of the kitchen water-trough desk without extra-opening, or may be directly fixed above the bottom of the water-trough after removal of the drain-panel.
