Description

Technical Field

[0001] The utility model relates to the technical field of rotary printing, in particular to a water circulation heat dissipation structure of a rotary printing device. 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 mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate and mounted on the printing press. Then, ink is applied to the places with text and images on the printing plate manually or by the printing press. Then, the ink is directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating printed products identical to the printing plate. The invention and development of the printing press plays an important role in the spread of human civilization and culture. According to the classification of printed paper, printing presses can be divided into sheet-fed printing presses and rotary printing presses, which are also called roller printing presses. Due to the high printing efficiency of rotary printing presses, they are widely used in large printing plants.

[0003] During the rotary printing process, a large amount of heat will be generated due to high-speed operation and rapid drying of ink and printing ink, which poses a threat to the printing quality and stable operation of the equipment. Therefore, heat dissipation becomes an important link in rotary printing to ensure the normal operation of the equipment and extend its service life. Utility Model Content

When the utility model is in use, a worker adds water into the water tank through a water inlet pipe, cools the water in the water tank through a cooler, starts a water pump through an external power source, and the water pump extracts water into the water pump through a water pump pipe, and then outputs cooling water to the inside of a circulation pipe through an output pipe. A printing object enters the inside of a printing device body from a feed inlet, and the rotary press cooperates with the ink cartridge to perform ink jet printing. After a long period of operation, the temperature inside the ink cartridge is high, and the ink inside the ink cartridge becomes viscous due to the high temperature. When the cooling water enters the inside of the circulation pipe, the outer shell of the ink cartridge is cooled, so that the temperature inside the ink cartridge is reduced.

[0016] 2. When the utility model is in use, the air temperature around the ink cartridge is relatively high, and the heat flow around the ink cartridge is dissipated to the outside through the rotation of the heat dissipation fan. At the same time, the cooling water passes through the pressure of the water pump after use and then enters the inside of the thick pipe through the reflux pipe. A filter is arranged inside the thick pipe, and the used cooling water is filtered through the filter. The filtered cooling water enters the inside of the water tank and is then cooled by the cooler. At the same time, when part of the moisture inside the water tank evaporates in the inside of the recirculation pipe after circulation, the moisture entering the inside of the water tank becomes less and less, and moisture can be continued to be added to the inside of the water tank through the water inlet pipe. At the same time, the threaded rod is rotated to move upward on the inner wall of the thick pipe. After movement, the threaded rod is detached from the inside of the clamping block. After detachment, the threaded rod can be detached from the inside of the clamping hole. At this time, the connecting strip can be pulled to remove the filter from the inside of the thick pipe for replacement and cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
