Printing Roller

Functions and Features The rubber coating roller is an important accessory for the production enterprise to carry out the material conveying process in the production process, and it is also an important part of the transportation and transportation system. The rubber coating roller is used for packaging and processing the roller, and according to the production requirements of different production enterprises, the drum body of the roller is wrapped or cast. It is mainly divided into cold vulcanization and hot vulcanization methods, which are commonly referred to as encapsulation and casting. The casting rubber is a uniform layer of rubber material wrapped around the drum, and the production of the hot-glued casting rubber is more effective when used in production operations. However, the production cost of the casting rubber is relatively high. After the wear of the roller rubber surface appears on the production site, the conveyor bolts are exposed and the top tape is broken, and the rubber surface is difficult to repair immediately. The manufacturing process of hot-stick adhesives is relatively complicated. Not only does it take a long time to maintain, but also the intensity and difficulty of production work are high, and the requirements for production workers are also high. Therefore, it is difficult to meet the needs of large-scale production enterprises. The cold-vulcanized casting rubber is exposed between the upper and lower belts of the drive roller, and the selected rubber material is uniformly adhered to the surface of the roller with a normal-temperature-curing adhesive, thereby increasing the friction between the belt and the roller. force. The drum adopting the cold vulcanization rubber packaging method eliminates the heavy work of disassembling the drum and the belt, and the production process is simple. It saves labor and time in production and production, and not only the production cost is relatively low, but also used in production operations. The effect is also better. Cold glue sticking glue In the production operation, if the roller rubber surface appears damaged or worn, the drum can be repaired on the spot. At present, the cold glue sticking process is widely used. Therefore, the drum adopting the cold glue sticking process is one of the most commonly used fittings used by factories and mines in production operations for material transport production.

The water roller and the ink roller are all kinds of rollers used in the printing machine. A water roller is a roller that applies a dampening solution onto a plate in a lithographic printing press. His production of raw materials is water fleece, water jacket, so it has a very good hydrophilic properties. Because the fleece sleeve has countless pores, all the water rollers also have good water absorption properties. These two properties ensure that it can provide good wetting of the printing plate. An ink roller is a rubber roller that applies ink to a printing plate.

At present, China's rubber roller sales market is still uneven and uneven, and the high-quality, reliable and reliable rubber roller needs a large amount. It is very demanding in the water roller and UV roller market. In order to ensure the market share in China, Large and medium-sized companies in China should increase the scope of product research and development, focusing on improving the quality of commercial rubber rollers, especially in high-end rubber rollers, improving the reliability of products and improving the after-sales service system. The rubber roller manufacturing industry has greatly improved and upgraded. The French rubber roller sales market is an institutional and technical upgrade. It is this fair and just confrontation.
