Description

Technical Field

[0001] The invention relates to the technical field of printing and drying devices, and in particular to a printing and drying device for a packaging box. Background Art

[0002] Printing is to transfer ink to the surface of paper, textiles, plastics, leather, PVC, PC and other materials through processes such as plate making, inking and pressurization of originals such as text, pictures, photos and anti-counterfeiting. After printing, the print needs to be dried by a printing dryer. The Chinese patent announcement number CN116061549B discloses a printing and drying device for packaging boxes, including a base and a printing mechanism arranged on the base, and also includes: a rotating plate, which receives the drive of a first driving mechanism to rotate and is arranged on the base, and is used to carry the packaging box; an inking mechanism, which intermittently and passively inks the silk screen on the printing mechanism when the rotating plate moves the packaging box, and the silk screen can be inked intermittently and passively as the rotating plate moves the packaging box, so that the ink on the silk screen is always kept in a sufficient state, avoiding the subsequent printing effect affected by insufficient ink caused by the staff forgetting to ink.

[0003] In the above-mentioned prior art, when printing and drying the packaging box, a reciprocating walking printing dryer is often used for drying. The existing walking printing dryer often adopts a module plate arranged on the side of the shell close to the transmission platform, and a cover plate is arranged on the top. When maintaining the printing dryer, the cover plate is removed to maintain the module plate. Since the internal space of the printing dryer on the transmission platform is narrow, it is not convenient to carry out maintenance work. In addition, when the packaging box is printed, the volatilized ink adheres to the mesh plate, which is not easy to remove and clean, and is not convenient to use. Therefore, a printing drying device for packaging boxes is proposed. Summary of the invention

[0004] In order to solve the problem that a reciprocating walking printing dryer is often used for drying when printing and drying a packaging box, the existing walking printing dryer often adopts a module plate arranged on a side of the shell close to the transmission platform, and a cover plate is arranged on the top. When maintaining the printing dryer, the cover plate is removed to maintain the module plate. Since the internal space of the printing dryer on the transmission platform is narrow, it is not convenient to carry out maintenance work, and when the packaging box is printed, the volatilized ink adheres to the mesh plate, which is not easy to remove and clean, and is not convenient to use. The present invention provides a printing drying device for packaging boxes.
