Description

Technical Field

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

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, ink is applied to the places with text and images on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating the same printed product as the printing plate. The invention and development of the printing press plays an important role in the dissemination of human civilization and culture. After the printed product is removed, it needs to be quickly dried to ensure the quality of the printed product, so a drying device is needed.

[0003] When existing heating devices heat and dry paper, they usually use a heating structure in conjunction with a fan to dry the text on the paper. This heating method will not only cause the hot air to blow directly and cause the paper to deform, but also cause the ink of the printed patterns and text to be blown away, making the handwriting or pattern blurred.
