The requirements of the roller when it is made

Speaking of rollers, on the other hand, it is actually called a roller. To a large extent, it is actually widely used in rotary screen printing machines and its digital Above the printer, and in terms of roller equipment, it is used in different types of transmission and conveying systems and sorting and conveying equipment such as mine conveying equipment, papermaking and its packaging machinery.

The roller should have sufficient rigidity. Therefore, we should pay attention to the fact that the bending deformation will not exceed the allowable value under the action of heavy load. Next, as far as the surface of the roller is concerned, it should be noted that it should have sufficient hardness, and the general requirement is actually to reach HRC50 degrees or more. Has relatively strong corrosion resistance.

In fact, the coating on the roller will have a certain anti-peeling ability, so to a large extent, it can directly ensure that the working surface of the roller will have better resistance. Abrasiveness and its corrosion resistance.

Then, to a large extent, the working surface of the roller should pay attention to fine processing. In terms of six aspects, to a large extent, it will directly ensure the dimensional accuracy and Surface roughness. And the roughness should be above Ra0.16, and there should be no pores or grooves. As far as the wall thickness of the working surface of the roller should be kept uniform, otherwise, the chrome-plated roller manufacturer will directly lead to the uneven temperature of the roller surface to a large extent, which will affect the quality of the product. quality.

Next, for the material of the roller, it should be noted that it has better thermal conductivity. Generally speaking, the manufacturers of chrome-plated rollers should pay attention to the use of chilled cast iron to a large extent. , under special circumstances, it should be noted that the use of cast steel or molybdenum-chromium alloy steel, whether it is heating or cooling, the rope drum can achieve the purpose of rapid and uniform.
