Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a drying device for printing. Background Art

[0002] Printing is a technology that transfers the ink of text, pictures, photos, anti-counterfeiting manuscripts to the surface of paper, fabrics, plastics, leather and other materials through plate making, inking, pressurization and other processes to reproduce the contents of the manuscripts in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. In the literal sense, leaving traces is called printing, rubbing is called brushing, and rubbing with a brush to leave traces on other objects is called printing. In short, printing is the industry of producing printed materials. The production of printed materials is similar to that of seals. First, the seal (plate) is engraved, and then the seal (plate) is stained with printing oil. Then the printing oil on the seal (plate) is transferred to paper, silk, leather and other substrates to form a printed product. In order to avoid damage to the printed pattern after printing, the printed ink needs to be dried to improve the printing effect. At first, there are some problems in the existing printing drying device during the drying process:

[0003] Drying is not thorough. Since the ink in the printing process is applied to the surface of paper or fabric, when the ink is used too much and accumulated, the existing drying device cannot quickly dry the ink deep inside, and can only dry the surface ink, which will cause the printed pattern to be damaged during the storage process, reducing the overall printing quality.
