Four Roll Rubber calender

Four Roll Rubber calender
Four-roll rubber calender machine is the most technologically advanced and highly efficient precision calendering equipment in the rubber industry. The four precision rollers are typically arranged in an "L", "Γ", or a diagonal "Z" shape, allowing for simultaneous double-sided coating of fabric reinforcement in a single pass.
It represents the pinnacle of high-efficiency, high-precision, and highly automated calendering technology, and is a core piece of equipment for the production of large tires, high-end conveyor belts, and high-quality composite products.

Advantage and Main Feature

1.Roller: Chrome-plated roller, roller surface hardness can reach 70±2 HSD.


2.Rolling bearing: Automatic aligning roller bearing, high carrying capacity, energy saving more than 5% than the traditional nylon bush.


3.Bearing lubrication: Automatic lubrication device, perspective materials are adopted to facilitate observation and timely replenishment of lubricating oil. Each pipe is equipped with a pressure gauge to prevent pipe clogging, improper lubrication caused by bearing damage


4.Nip adjustment device: Standard by motor automatic nip adjustment. Digital display for greater precision, and adopt PLC touchscreen to adjust it.


5.Ratio gear: forged and carburized chromium molybdenum alloy steel or forged 45# steel quenched and hardened.


6.Gear box (reducer): hard tooth surface reducer, adopt top brand in china, with four-axis three-stage transmission, the safety factor is above 2.0.


7.The frame and base: The frame is welded and annealed, and precision machine processed; the cover is steel and annealed;


8.Stock guide: Standard with manual control, movable. The material is MC nylon.

Option with hydraulic stock guide system for automatic control.


9.Safety Device: four emergency stop buttons, two installed on the front and back of the main machine. And one main control box stop button.

Utilizes electro-hydraulic brakes or emergency stop switches to activate reversing brakes. In emergency situations, the brake-applied roller rotates no more than 1/6 of a revolution.


10.Other configurations: Frequency inverter system, motor nip adjustment device, hydraulic brake
