Novel packing printer

Abstract

The invention discloses a novel packing printer. The packing printer comprises a frame, a printing roller and an ink pool; a dispersion roller floats on the surface of ink in the ink pool beside the printing roller; the dispersion roller comprises a nonmagnetic cylinder whose two ends are sealed through sealing covers; a spiral rod is spirally wound and fixed on the outer side wall of the cylinder; multiple airbags are uniformly distributed at the inner side periphery of the cylinder; multiple high-magnetism magnetic rings are arranged at the end parts of the airbags; and a charging barrel issurrounded in the center of the multiple airbags. Through arrangement of the dispersion roller, the defects in a traditional machine can be overcome, the ink at the front end of the printing roller isfurther uniformly distributed and dispersed, and the packing and printing quality is greatly improved. Meanwhile, the airbags are arranged inside to prevent the accident of the dispersion roller sinking to the bottom due to permeation of a lot of ink inside caused by weak sealing or cracking of the hollow cylinder of the dispersion roller. The charging barrel is arranged in the airbags for placing a ballast to adjust the depth of the dispersion roller sinking in the ink.

Description

technical field [0001] The invention relates to the technical field of packaging printing, in particular to a novel packaging printing machine. Background technique [0002] In the processing process of the prior art packaging printing machine, the workpiece to be printed passes through the printing cylinder and the ink pool, and the ink is applied to the workpiece. However, due to the continuous movement of the printing cylinder and the uneven viscosity of the ink, the ink near the printing cylinder attachment will A small amount of local unevenness occurs, resulting in low local printing quality. It is necessary to further disperse the ink in front of the printing cylinder to make the ink evenly distributed and improve the printing quality. In the prior art, a stirring drum and a stirring motor are often added at the front end of the printing drum, but since high-intensity dispersion stirring is not required there, adding a stirring drum and a stirring motor results in an ...

[0002] In the processing process of the prior art packaging printing machine, the workpiece to be printed passes through the printing cylinder and the ink pool, and the ink is applied to the workpiece. However, due to the continuous movement of the printing cylinder and the uneven viscosity of the ink, the ink near the printing cylinder attachment will A small amount of local unevenness occurs, resulting in low local printing quality. It is necessary to further disperse the ink in front of the printing cylinder, so that the ink is evenly distributed and the printing quality is improved.

In the prior art, a stirring drum and a stirring motor are often added at the front end of the printing drum, but since high-intensity dispersion stirring is not required there, adding a stirring drum and a stirring motor results in an increase in equipment costs and an extremely high operating cost. big waste
