The invention discloses a cleaning device for environment-friendly packaging machinery. The cleaning device comprises a housing, wherein a two-axis motor is fixedly connected to the top of the inner chamber of the housing; output ends of the two sides of the two-axis motor are fixedly connected to threaded rods; a threaded sleeve is arranged on the surface of each threaded rod in a sleeving manner; a connecting plate is fixedly connected to the bottom of each threaded sleeve; a partition is fixedly connected to the inner chamber of the housing; and a through opening is formed in the surface ofthe partition. As the housing, the threaded rods, the threaded sleeves, the two-axis motor, the connecting plates, fixed blocks, the partition, motors, through pipes, sprayers, water outlet pipes, water pumps, water inlet pipes, support legs, water suction pipes, a water tank, brushes, rollers, an activated carbon plate, the through opening, a chute, a rotary bar, a connecting rod, a pulley and awater passing hole are used in cooperation, the problem that a conventional cleaning device for the environment-friendly packaging machinery has a poor cleaning effect is solved. The cleaning devicefor the environment-friendly packaging machinery has the advantage of the good cleaning effect.
