Rotary press water cooling system

Abstract

The invention discloses a rotary press water cooling system, and belongs to the technical field of rotary presses. The rotary press water cooling system comprises a water cooling roller, a first rotary joint is arranged at one end of the water cooling roller, the inner side of the end, deviating from the water cooling roller, of the first rotary joint is in communication with the end close to a flow distribution pipe. According to the rotary press water cooling system, through the mutual cooperation of the designed structures such as a first main pipe, a second main pipe, a third main pipe, aball valve, a valve pipe, a bucket-shaped body, a water cooling body, a gas collecting hood, shells, female screw rods, male screw rods, turbines, separation membranes, flow distribution bodies and spray holes, the cooling effect of the water cooling roller in unit time can be effectively controlled, the stability of a temperature difference value between the surface temperature of the water cooling roller and the room temperature is kept, water spots generated on the surface of the water cooling roller due to the temperature effect are avoided, the layer of water vapor heat energy permeatinginto the water cooling roller is shallow, and normal work and application of the water cooling roller are not affected; and heat energy released by an LED drying lamp set and a lamp set controller isutilized, such that a certain energy-saving and emission-reducing effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of rotary printing machines, and in particular relates to a water cooling system for rotary printing machines. Background technique [0002] Commercial web offset printing machine is a kind of web offset printing machine. It is a web multi-color offset printing machine capable of printing more than 175 lines / inch of color fine print. Commercial web offset printing machine is mainly used for color magazines, high-end commercial advertisements, For the printing of high-end publicity materials, pictorials, etc., due to the increasing printing volume of high-end magazines and newspapers, the use of sheet-fed offset printing machines can no longer meet the growing market demand. Due to the expansion of the market, all famous printing equipment manufacturers have developed He has built his own high-end commercial web offset printing machine, and adopted a lot of advanced technology, with a printing speed of about ...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that during the printing process of the rotary printing machine, the upper and lower water-cooled rollers are in contact with the printed matter repeatedly, and the water-cooled roller rotates at a fast speed, which is very easy to generate heat, and the printed matter needs to be dried with a drying lamp before cooling. Dry treatment, because the heat energy released by the drying lamp is not very large, most of them are directly accompanied by the water cooling system for cooling treatment, which not only causes waste of heat energy, but also increases the work of the water cooling system. Afterwards, the large difference between the surface temperature and room temperature is prone to water stains, and there will be watermarks on the printed matter, which will affect the quality of the printed matter. A water cooling system for rotary printing presses is proposed.
