Description

Technical Field

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

[0002] Digital printing machines use digital printing technology to achieve high-quality printing of patterns on textiles, clothing and other materials. Compared with traditional printing technology, digital printing machines have the characteristics of high precision, free design, and high production efficiency. After the digital printing machine prints the dye, it needs to be dried by a drying roller.

[0003] At present, a Chinese utility model with publication number: CN219325661U discloses a drying roller of a digital printing machine, which belongs to the technical field of printing processing roller components. The utility model includes a roller body, an axle rod arranged inside the roller body, the axle rod is hollow, and a through hole located inside the roller body is opened on the surface of the axle rod. The number of the through holes is several and they are evenly and symmetrically arranged. The surface of the axle rod is fixedly connected with end covers, and the end covers are located on both sides of the roller body. The hot air inside the roller body of the utility model can enter the interlayer between the sleeve and the roller body through the opening, and the hot air circulating in the interlayer can be discharged to the outside of the sleeve through the exhaust groove, further increasing the contact area between the hot air and the printed product, so that the sleeve has the effect of directly drying the printed product, and solves the problem that the structure of the existing drying roller is relatively simple, and the moisture contained in the printed product is evaporated mainly by heat exchange. When the contact time between the printed product and the drying roller is short, the moisture cannot be repeatedly dried, which seriously affects the printing pass rate.

[0004] However, most of the existing drying rollers are not convenient for uniformly heating the surface temperature, so when the drying roller dries the printed matter after printing, it is easy to cause uneven drying of the moisture in the printed matter. In addition, due to the uneven surface temperature of the drying roller, the uneven high temperature parts of the drying roller are easy to cause damage and deformation to the surface of the printed matter. Therefore, a drying roller for a digital printing machine is proposed. Utility Model Content
