Abstract

The invention discloses an intermittent rotary printer with cooling units. The intermittent rotary printer comprises printing units, UV curing units and the cooling units; the cooling units are arranged between the printer printing units and the UV curing units; cooling transmission devices are respectively arranged between the printing units and the UV curing units; ice roller support plates are arranged on the side surfaces of support plates of the printing units; ice rollers are mounted on the ice roller support plates; one ends of the ice rollers are sleeved and linked with ice roller servo motors fixedly connected to the ice roller support plates; the ice rollers adopt a two-direction rotating drive form; the ice rollers are hollow cylinder roller bodies; water circulating devices are arranged on one side surfaces of the ice rollers; and ice roller guide rollers are mounted on the support plates below the ice rollers. The printer is added with the cooling units, is simple in structure, cools printing materials by the rice rollers in UV curing when guaranteeing normal printing, prevents the problems of material stretching and inaccurate printing positions caused by higher curing temperature of the printing materials, and improves the printing quality and the printing efficiency.

Description

technical field [0001] The invention relates to a printing unit in the printing and packaging industry, in particular to an offset printing unit of an intermittent rotary printing machine. Background technique [0002] At present, offset printing intermittent rotary printing machine is more and more recognized by users because of its high printing dot reduction rate, vivid color, wide application range of printing format and low investment. However, the offset printing intermittent rotary printing machines currently on the market need to be cured by a UV device when the ink is dry, and the curing temperature of the UV lamp is generally between 35-55°C, and the temperature of different types of lamps is also different. The printing is affected by the temperature. For larger film materials, the high temperature heating in the UV curing process will cause the printing material to stretch, which will affect the inaccuracy of the printing set and cannot meet the needs of users. ...
