Description

Improved rubber compression roller

Technical Field

The utility model relates to the field of machinary, especially, relate to rubber roll, especially a modified rubber compression roller.

Background

In the production and deep processing of plastic films and metal foils. In order to obtain a better rolling effect, a rubber compression roller, namely a tracking roller, a receiving and releasing roller, a rolling compression roller and the like is arranged at the rolling part. The rubber compression roller has the main effects that the air content involved between the wound film layers is reduced, and meanwhile, the air extrusion between the axial layers is uniform, so that a better uniform winding smoothness effect is obtained. Such rubber press rolls are usually made of a metal roll core or a Carbon Fiber composite (Carbon Fiber Reinforced Plastics) roll core covered with different kinds of rubber materials. According to the production of different types of films, the parameters of rubber such as hardness, medium and high diameter, conductivity value and the like are selected. The roller is usually a driven roller, and the rotation of the roller itself is realized by the friction driving force of the pressed film.

High in diameter means: the roller is in a 'waist drum shape', two ends are small, the middle is large, and the two ends to the middle are in a parabola shape. The diameter is high, namely the difference between the minimum value of the diameters at two ends and the maximum value of the diameter at the middle. Typically for a roll flattening action.

Along with the market demands of high speed and large width, the rubber rolling compression roller in the film production process can be widened along with the film, the diameter of the roller body can be increased, the whole weight of the roller body can be increased, the deflection deformation of the roller body can be increased, and the adjustment can be brought to the high-value parameters in the matched rubber surface. Because the surface of the rubber press roll is made of rubber materials, the diameter is high, and the wear is easy to occur in the production process, and the rubber press roll needs to be replaced and maintained frequently. For the production line with the width of more than 8-10 meters, the maintenance process often needs to be stopped, the production efficiency is influenced, and the maintenance cost is increased. The overweight roller body can also increase the energy consumption of transmission. The friction force of the surface needs to be increased during transmission, and the slipping phenomenon of the optical-grade film can cause the surface of the film to be scratched. In the case of optical films, scratching means that the product is scrapped.
