The invention discloses a connecting pipe for a thermal blowing device. The connecting pipe comprises a connecting pipe body, wherein the outside of the connecting pipe body is wrapped with a heat insulating layer. According to the connecting pipe, the outside of the connecting pipe body is wrapped with the heat insulating layer, and thus the heat insulating function in the process that hot air reaches a blowing pipe can be achieved and the effects of energy economization and environment friendliness are achieved.
Description
Technical field [0001] The invention relates to a hot air blowing device, in particular to a connecting pipe for the hot air blowing device. Background technique [0002] The offset printing machine includes a plate cylinder, a blanket cylinder, and an impression cylinder. The ink delivery system and water delivery system of the offset printing machine supply ink and fountain solution to the printing plate of the printing plate cylinder. Using the principle of immiscibility between oil and water, the graphics and text on the printing plate are ink-friendly, and only the ink supply system is accepted. Ink: The blank part is hydrophilic and only accepts fountain solution. The printing plate cylinder transfers the graphics and text that have received ink and fountain solution on the printing plate to the blanket cylinder, and the blanket cylinder transfers the printing plate. Graphic ink and fountain solution are printed on the paper bitten by the impression cylinder to complete on...
