The role of rollers in calenders
The calender is one of the basic equipment in the plastic production process. It can form plastic or other materials into materials of a certain thickness by controlling speed, excitation and other conditions.
There are two or more rollers in the calender. The rollers are arranged in a certain form to compress rubber or plastic. The following are the uses of rollers in calenders.
1. Shaping rubber and plastic materials. The rollers in the calender are connected by a transmission, and as the plastic or rubber passes through these rollers, pressure is exerted between the rollers. Under the combined action of friction and pressure, the rubber or plastic deforms to the required thickness.
2. Print. Rubber and plastic materials are pressed and colored by rollers in the calender, thereby lengthening, thinning, and widening, and finally reaching the desired size and thickness. At the same time, the surface of the roller is generally flat, and the pattern can also be customized according to needs to imprint rubber and plastic materials into the required shape.
3. Control the calendering effect. When rolling rubber and plastic materials, the speed of rolling is very important. The running speed of the roller needs to be determined according to the material and size of the rubber and plastic material. Therefore, adjusting the speed of the roller according to the actual situation can ensure the processing quality of the rubber and plastic material and guarantee the next step of processing.
