The double-facer of the cardboard production line is an indispensable and important equipment in the cardboard production line.
The double-facer of the cardboard production line is an indispensable and important equipment in the cardboard production line. Its product introduction can be carried out from the following aspects:
1. Basic Overview
The double-facer of the cardboard production line, also known as the heating laminating machine, is a key single machine in the corrugated cardboard production line. Its main function is to bond, heat and solidify the single-sided corrugated cardboard and the face paper, and then dry and cold-form them into high-quality three-layer, five-layer or seven-layer corrugated cardboard. In this process, the double-facer not only improves the physical properties of the cardboard, but also ensures the structural stability and aesthetics of the cardboard.
2. Components
The double-facer is mainly composed of the following key parts:
Heating section: including the heating plate (also known as the hot plate or flat drying cylinder), which is used to gelatinize, bond, and solidify the adhesive, and evaporate the moisture in the adhesive to form a straight and firm cardboard. The heating plate is usually a thick-walled hollow metal container, which is heated by high-temperature steam.
Cooling section: The function of the cooling section is to further evaporate the moisture of the corrugated cardboard and cool it to shape. It usually includes cooling main beams, crossbeams and cold plate components, etc., and the cardboard reaches the final stable state through cooling.
Conveyor belt: It is divided into upper conveyor belt and lower conveyor belt, which is mainly responsible for driving and pulling corrugated cardboard, transmitting laminating pressure, and absorbing moisture evaporated from the cardboard. The conveyor belt needs to have good softness, hygroscopicity, air permeability, wear resistance and high temperature resistance.
