Description

Technical Field

[0001] The utility model belongs to the field of printing, and in particular relates to a printing plate roller cooling device. Background Art

[0002] Printing is a technology that transfers ink to the surface of paper, fabric, plastic, leather and other materials through processes such as plate making, inking and pressurization to copy the content of the original manuscript in batches. The printing plate roller is also called a steel roller, which can be divided into hollow rollers and solid rollers, shaft rollers and non-shaft rollers. It is generally used for plate making. The surface of the roller is copper-plated, and the pattern is engraved by a gravure electronic engraving machine, and then a layer of chrome is plated. After completion, it is delivered to the printing factory and is often used for printing plastic packaging.

[0003] The working principle of a printing press is: first, the text and images to be printed are made into a printing plate and installed on a printing press. Then, ink is applied to the places with text and images on the printing plate manually or by a printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate. The printing plate roller and the impression roller need to be used together during the printing process.

[0004] The prior art has the following deficiencies: after the existing printing roller is used for a long time, the heat accumulated causes the printing plate roller to heat up. If the machine is not stopped in time to cool down, the printing effect will be poor due to its own high temperature, causing the aging of the printing plate roller. In severe cases, it may even cause damage to the printing machine, increase the user's maintenance cost, reduce the printing efficiency and the service life of the printing plate roller, and bring great trouble to the user.

[0005] Therefore, a printing plate roller cooling device is necessary. Utility Model Content
