The utility model belongs to the technical field of ink-jet printing machines, and particularly relates to a continuous ink-jet printing
machine which comprises a conveying belt, an adjusting ink-jet printing structure installed at the left end of the top face of the conveying belt, a clamping structure installed at the bottom of the adjusting ink-jet printing structure, and a
drying structure installed at the right end of the top face of the conveying belt. The adjusting unit comprises an asynchronous motor, the output end of the asynchronous motor is connected with a
threaded rod, the outer surface of the
threaded rod is connected with a sleeve, a sliding block is installed on the outer surface of the sleeve, a first
hydraulic cylinder is installed on the bottom face of the sliding block, a first telescopic rod is installed in the middle of the bottom face of the first
hydraulic cylinder, and a code spraying
machine is installed at the bottom end of the first telescopic rod. According to the continuous ink-jet printing
machine, the asynchronous motor is used for driving the
threaded rod to rotate, the sleeve drives the sliding block to move when the threaded rod rotates, and therefore the first
hydraulic cylinder, the first telescopic rod and the ink-jet printing machine are driven to move, the first hydraulic cylinder and the first telescopic rod can effectively adjust the height of the ink-jet printing machine, and the ink-jet printing machine can conduct ink-jet printing more flexibly.
