It is also one of the core equipment of tile line, can be said to be the heart of tile line, its main role is to tile paper pressure tile and paper fitting molding, the final formation of two layers of single-sided corrugated board.It is mainly composed of base paper temperature, humidity adjustment part, pressure tile forming part, sizing part, fitting part, guide part, transmission and other parts of the combination. The temperature and humidity adjustment part is composed of preheating roller and spray humidification system, etc. Speaking of these, we must be curious why to adjust the temperature and humidity? What’s the point of adjusting that? Let me talk about it for you: the size of the humidity has a great impact on the size change of the base paper, the dry humidity of the base paper itself will affect the absorption of water in the glue. Temperature is one of the important conditions for humidity adjustment of base paper. The temperature of base paper itself plays an important role in the bonding of glue and base paper. Changing the relative humidity of the base paper is conducive to the absorption of moisture in the glue, so that the glue coated on the paper can mature in a suitable time, which is conducive to bonding. At the same time, it can also eliminate the wrinkling of the surface of the base paper caused by excessive moisture, and control the humidity of the base paper and the humidity of other machine positions can also control the bending of the board. The pressure tile forming part is mainly composed of upper and lower corrugated roller, pressure roller, strong paper mechanism and so on. The role of the upper and lower tile roller is to make tile paper corrugated molding, “at present we commonly used corrugated for UV shape, less use is u-shaped corrugated and V-shaped corrugated.V-shaped corrugated cardboard has higher hardness and stiffness, but there are also shortcomings, V-shaped corrugated corrugated peak and coating roller contact surface is small, so the glue is also small, in theory, to save glue, but the peak is easy to wear, short service life, and because of the peak is pointed production is easy to crush corrugated. The compressive strength of U-shaped corrugations is lower than that of V-shaped corrugations. At the same time, due to the large circular arc of corrugations, the wear is slow and the life is slightly longer than that of V-shaped corrugations. Because the U-shaped corrugated peak is smooth, it will not cut off the phenomenon of corrugated paper, but because the peak radian is large, the contact surface between the peak and the rubber roller is large, so the glue is relatively large, and the glue consumption is also large. UV corrugated is a kind of corrugated between U and V, absorbing the advantages of both, so it is the most widely used. ” Under tile roll and pressure roll is mainly tile paper and paper together.
