Description

Technical Field

[0001] The utility model relates to a roller, in particular to a roller with a cooling function, belonging to the technical field of cooling rollers. Background Art

[0002] A roller is a cylindrical component, usually made of metal or other materials. It can rotate and transfer or carry objects on its surface. It is often used in industrial processes such as material transportation, printing, rolling, and extrusion. The structural characteristics of the roller can provide stable rotation and load-bearing capacity. It can be smoothed, textured or coated according to specific needs to adapt to different materials and process requirements. It is fixed to the equipment through a bearing seat, bracket or other structure, and is used in logistics, printing, papermaking, packaging, metallurgy, textile and other industries.

[0003] Existing rollers are generally composed of a roller body, a roller shaft and a bearing, and do not have a cooling function. When in some high-temperature environments or after the roller has been running for a long time, the roller will generate a lot of heat. The high temperature will cause the roller to deform and reduce the quality of the product. Overheating of the roller will cause accelerated wear of the roller and shorten the service life of the roller, which is not conducive to the use of the roller. In addition, when the roller is overheated during production, it needs to be stopped for cooling, which greatly reduces production efficiency.

[0004] Therefore, it is urgent to improve the roller with cooling function to solve the above-mentioned problems. Utility Model Content
