Two-roll calender

The two-roll calender is widely used in the field of polymer material processing, mainly for continuously forming thermoplastic or thermosetting materials into films, sheets, or composite products through heating and roller pressure.
Its core application scenarios cover multiple industrial fields such as rubber, plastics, artificial leather, papermaking, and electronic materials. For example: rubber industry, plastics and film manufacturing, composite materials and functional materials, special industrial materials.

Product Features: Multi-roller structure design, high-rigidity frame, precise gap adjustment system, good temperature control uniformity, high degree of automation integration.

Advantages: High production efficiency, excellent product quality, strong process adaptability, energy-saving and environmentally friendly design, intelligent monitoring and convenient maintenance.

Application: This rubber two-roll calender is mainly suitable for calendering rubber sheets of different widths such as conveyor belts and rubber sheets, and for laminating tire tread cushion layers in tire factories. It can be matched with a composite tread extrusion tandem production line.

Structural Features:

1. The base is an integral welded base, which has been annealed for good stability;

2. The bearings at both ends of the roller are rolling bearings, resulting in high precision of the produced rubber sheet and long service life of the equipment;

3. The gap adjustment method is electric adjustment or manual adjustment;

4. The lubrication method is thin oil lubrication. When the main machine is started, the lubrication oil must be started, and oil is supplied in real time to ensure the equipment is not short of oil;

5. The motor adopts a variable frequency motor plus a variable frequency speed regulator for adjustment;

6. The roller material is chilled alloy cast iron, and the surface smoothness can reach a mirror finish according to requirements. The reducer is a hard-tooth surface square box reducer with long service life and low noise;

7. The motor adopts a variable frequency motor plus a variable frequency speed regulator for adjustment.
