High Quality Four Roll Rubber Calender The Thickness Of The Rubber Sheet Can Be Accurately Controlled
Introduction to rubber calender:
There are several common classification methods for the models of four-roll rubber calenders:
1. Classification by the length of the working part of the roller:
- Short working length type: such as some small four-roll rubber calenders, the working length may be around 600mm-1000mm, suitable for small-scale experiments and production in small rubber product companies or laboratories.
- Medium working length type: The more common models are 1200mm-1700mm working length, which are widely used in rubber product production and can meet the general scale production needs, such as the production of some moderate width rubber sheets, rubber plates and other products.
- Long working length type: large four-roll rubber calenders with a working length of more than 1800mm. This type of equipment has a strong production capacity and is suitable for large-scale continuous production in large rubber product companies. It can produce rubber products with a larger width, such as large rubber conveyor belts, etc.
2. Classification by roller diameter:
- Small diameter roller type: The roller diameter is small, usually around 200mm - 300mm. This type of calender is suitable for fine calendering of rubber materials, such as producing some thin rubber sheets or rubber films with high precision requirements.
- Medium diameter roller type: The roller diameter is between 350mm - 500mm. It is a more commonly used model that can meet the production needs of a variety of rubber products and has good performance in the production of rubber sheets, rubber sheets and other products.
- Large diameter roller type: The roller diameter is above 600mm. This large four-roller rubber calender is suitable for large-scale calendering of rubber materials. It can withstand greater pressure and load and is often used to produce thick rubber sheets, large rubber tire treads and other products.
3. Classification by roller arrangement:
- Type I: The four rollers are arranged in parallel up and down. This arrangement is simple in structure and easy to operate. It is suitable for the production of some rubber products that do not require particularly high calendering precision.
- T-type: three rollers are on the same horizontal plane, and another roller is in the vertical direction. This arrangement can make the rubber material subject to forces in different directions during the calendering process, which is conducive to improving the quality and performance of rubber products. It is often used in the production of rubber plates, rubber sheets and other products.
- L-type: two rollers are on the same horizontal plane, and the other two rollers are at a certain angle to the horizontal plane. This arrangement can save space and is suitable for some companies with limited production space. At the same time, it can also meet certain calendering production needs.
- S-type: four rollers are arranged in an S shape. This arrangement can make the rubber material subject to more uniform pressure and shear force during the calendering process, thereby improving the quality and precision of rubber products. It is often used in the production of rubber products with high calendering quality requirements, such as high-end rubber seals, rubber shock-absorbing products, etc.
- Z-type: the arrangement shape of the four rollers is similar to the letter "Z". This arrangement can reduce the elastic deformation of the rollers and facilitate feeding. It is also widely used in the rubber industry.
Some common four-roll rubber calender models include XY-4γ630, XY-4γ1120, XY-4γ1400, XY-4γ1730, XY-4γ2130, etc. The numbers in these models usually represent the working length of the roller and other parameter information. The model naming methods of different manufacturers may vary, but they are basically named around the key parameters such as the size, arrangement, and working length of the roller.
