There are four rollers of the calender machine, roller arrangement in the form of T-type, L-type, S-type and Z-type, with high efficiency, high precision.
In the rubber industry is mainly used for the fabric of the adhesive, the steel cord of the paste, the pressure of the compound, the rubber blank, paste the film and multi-layer film and so on. Z-type roller which arranged a reasonable, can reduce the elastic deformation of the roller, easy to feed, so the application of a wider.
Working principle:
One of the necessary working conditions for the calendering process: the friction angle of the compound and the roller must be greater than the contact angle α, and the compound will be pulled into the roll. In the process of rolling, the roller is operated at a certain speed ratio, further kneading and increasing the plasticity of the compound, and finally rolling through the minimum roll distance into a film having a certain thickness and width ; In the roller squeeze force, the film squeeze in the textile or steel cord. Some need to be pressed into a certain pattern and shape, and some need to be multi-layer use, color, and shape of the film together.
