    TECHNICAL FIELD
  • This invention published a continuous roller press with flexible heating plate. It belongs to the technical field of wood working mechanicals technology.
    • TECHNICAL BACKGROUND
  • The structure and the working principle of the present continuous roller hot press for the production of MDF and particleboard is as shown in fig 1. The feeding belt conveyor transfers MDF mat or particleboard mat into the gap between the main pressing drum and the steel belt where the mat is first compressed and heated up from both sides by the main pressing drum and the steel belt. After running for roughly 3 meters the mat is compressed by the pressing drum the second time. The steel belt is heated up also by the pressing drum. After roughly 2 meters more the mat reaches another pressing drum. The mat is compressed the third time and the steel belt is heated up one more time by the pressing drum. The raw panel is made when the mat is transferred between the main pressing drum and the steel belt up to the outlet of the press.
  • Nearest prior art document US5,527,422 to Sulzer-Escher Wyss A.G . discloses a machine for continuous manufacture of chipboards, fibreboards and similar products. EP 1391279 to Voith Patent GmbH discloses an apparatus with controlled flexure rollers for making webs. This patent discloses the use of multiple rollers positioned behind a steel band; where the rollers are capable of controlling the pressure on the web.
  • The disadvantages of the present press are as below. First of all the time for the first compression step is very short. The high density layers on the surfaces of the panel are very thin. The second, the heat reserved on the steel belt is very limited. Even though it is heated up two more times by the pressing drums the heat energy is still insufficient for the process. As the result the mat can not be sufficiently compressed when the core layer of the mat is heated up to the softening temperature.

    • CONTENT OF THE INVENTION
  • This invention provides a continuous roller press with flexible heating plate without the disadvantages of the present roller press described above i.e. insufficient pressing and heating.
  • The solution of this invention is as below. Guiding drum, driving drum and tension drum are installed in the press frame in a triangular shape. The driving drum is connected to a gear reducer which is driven by a variable frequency driving motor. The main pressing drum is installed between the guiding drum and the driving drum. The main press drum and the guiding drum constitute the first pressure application mechanism of the press. Thermal oil channels are arranged in the shell of the main pressing drum. The surface profile of the main pressing drum is shaped in such a way that the diameter in the middle is a little bit bigger than on both of the ends. The circular steel belt cinctures the guiding drum, the main press drum, the driving drum and the tension drum so that a closed heat transfer and driving mechanism is formed. The steel belt transfers the driving force from the driving drum to drive the other drums. The whole system transfers the heat and pressure to the mat. It is characterized in the arc-shaped flexible heating plate with internal thermal oil channels. The heating plate is pressed against the main pressing drum by hydraulic cylinders via the roller carpet and the steel belt to form the heat and pressure transfer mechanism. Two groups of hydraulic cylinders are installed at the press inlet zone and the press outlet zone respectively. The heating plate inlet is hinged to the press frame by hydraulic cylinders to adjust the inlet angle. The heating plate outlet is hinged to the press frame by hydraulic cylinders to adjust the pressure between the heating plate and the main pressing drum. Roller carpet consists of roller rods and roller chains. The roller carpet is also a circular shaped. At the outlet of the press the roller carpet is driven by variable frequency drive motor via sprockets. The roller carpet is installed between the heating plate and the steel belt to transfer heat and pressure from the heating plate to the steel belt. The roller carpet is tensioned by a pneumatic tension device installed in the inner side of the roller carpet.
  • The driving drum is driven by motor via gear reducer with variable frequency inverter. The steel belt is driven by the driving drum due to the friction between the drum surface and the steel belt. The steel belt drives the tension drum, the main drum and the guiding drum. The mat passes through the gap between the main pressing drum and the steel belt. The pressure and the location of the hydraulic cylinders can be adjusted according to the process. Under the combined function of the pressure and the heat the mat in converted into finished panel.
  • The positive function of this invention is that the flexible heating plate is adapted to apply the pressure and the heat to the mat continuously. And also the pressure and temperature can be adjusted freely according to the process. The performance of continuous flat press can be achieved by this new type of roller press. The density on the surfaces can be higher and the surface quality is better than the present roller press. The heat transfer from the steel belt to the mat is higher which makes the heating on both sides of the mat more balanced. By better balanced heating on both sides of the mat the core layer density of the mat is higher resulting in higher internal bond property of the finished panels. Comparing with the present roller press the bending strength of the finished panel increases 30%, the internal bond increases 50%, the resin consumption reduces 40%, the production efficiency increases 5%.
