Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing, in particular to a circulating cooling mechanism of a five-color printing device. Background Art
[0002] Printing technology, as a technology that transfers ink from text, pictures, photos, etc. to paper and various fabrics through plate making, inking and pressurization, plays a pivotal role in modern society. Its mass reproduction characteristics make information dissemination faster and more extensive, satisfying people's consumption demand for culture and artworks.
[0003] However, in the continuous production process of printing, especially in multi-color printing equipment, due to the continuous friction between the printing cylinder and the substrate, local heat accumulation is likely to occur in a specific area of the cylinder. This heat accumulation may not only cause damage to the equipment itself, but more importantly, it will affect the performance of the printing ink.
[0004] As we all know, the performance of ink is closely related to temperature. As the temperature rises, the viscosity of the ink changes. Viscosity is an important indicator of ink fluidity and adhesion, which directly affects the distribution of ink on the roller and the amount of ink transferred to the substrate. When the viscosity of the ink decreases, the fluidity of the ink increases, which may cause blurred printed patterns or excessive ink penetration; when the viscosity increases, the adhesion of the ink increases, but it may cause uneven ink transfer or blockage of the roller.
[0005] In multi-color printing, since multiple colors of ink are needed, the performance of each ink and the degree to which it is affected by temperature may be different. Therefore, if the printing equipment does not have a corresponding cooling mechanism during continuous use, the local heat accumulation of the roller will directly affect the performance of the ink, and then affect the quality of the substrate, causing fluctuations in the quality of the substrate.
[0006] In order to solve the above problems, ensure that the printing equipment can operate stably during the continuous production process, and at the same time ensure the stability of the quality of the printed materials, this patent proposes a circulating cooling mechanism for the five-color printing equipment.

[0016] The beneficial effects of the utility model are:
[0017] The utility model can keep the ink quality stable. The performance of the ink is closely related to the temperature.

The temperature of the printing roller can be controlled through circulating cooling, thereby improving the color reproduction, clarity and detail performance of the printed matter.
[0018] By lowering the temperature of the printing roller, the drying and clogging of ink caused by high temperature can be reduced, thereby maintaining the continuity and stability of the printing process, reducing downtime and printing time, and improving production efficiency;
