Requirements for rollers during production

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.

As far as the coating on the roller will actually have a certain anti-peeling ability, the chrome-plated roller manufacturer can directly guarantee the working surface of the roller to a large extent. Good wear resistance as well as 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. Textured chrome plating means that 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 the quality of the product.

Next, the material of the roller should pay attention to good thermal conductivity. Generally speaking, the textured chrome plating should pay attention to the use of chilled cast iron to a large extent. In special circumstances, it should be noted that the use of cast steel or molybdenum-chromium alloy steel, whether it is heating or cooling, can achieve the purpose of rapid and uniform.
