The invention discloses a printed matter surface drying mechanism. The printed matter surface drying mechanism comprises an upper roller and a lower roller which are mounted on a printing machine frame in a rotary manner, wherein a plurality of upper pinch rollers and lower pinch rollers are respectively mounted on the upper roller and the lower roller; the plurality of upper pinch rollers and lower pinch rollers are mutually staggered; air cavities which are communicated are respectively defined inside the upper roller, the lower roller and the plurality of upper pinch rollers and lower pinch rollers; a plurality of air outlets are respectively formed in the periphery of the outer circular surfaces of the plurality of upper pinch rollers and lower pinch rollers; hemispherical plugs are respectively arranged inside the plurality of air outlets. The printed matter surface drying mechanism disclosed by the invention is reasonable in structure, utilizes the pinch rollers on the rollers of the existing printing machine, is provided with the air cavities in the rollers and the pinch rollers, air outlets in the outer circular surfaces of the pinch rollers and the hemispherical plugs in the air outlets, so that when the printed matter passes through the pinch rollers, the hemispherical plugs float in the air outlets respectively and continuously rotate to enable air to dry the surfaces of the printed matters sequentially, therefore, the printing quality can be ensured.
Description
technical field [0001] The invention relates to the field of printing equipment, in particular to a printing surface drying mechanism. Background technique [0002] In the field of printing, printing presses are common production equipment. In the prior art, the printed matter passes between the rollers located in each printing area in the printing machine. In order to ensure that the fonts or patterns printed in each printing area will not interfere with each other, in the transition area between each printing area Make the transition while getting to air dry. However, in areas with relatively cold climate conditions, when the paper is in the transition area between the various printing areas, it is not well dried naturally, thus affecting the printing quality. Contents of the invention [0003] The object of the present invention is to provide a kind of printed matter surface drying mechanism, utilize the pressing roller on the rotating roller of existing printing mach...
