The plate blank runs along with the steel belt, the hot pressing time of different stages of different pressures and temperatures required by the plate manufacturing process is completed in the whole hot pressing plate area, and then the finished plate is gradually separated from the steel belt under the driving of the steel belt and is sent to a plate discharging conveyor.
In recent years, people have higher requirements on environmental protection, and a formaldehyde-free MDI adhesive is generally applied to artificial board products. The artificial board of MDI glue is pressed by a press, the process requires that the hot pressboard is set to have higher temperature, and because the traditional press has no cooling and shaping function, the temperature of the finished board discharged from the press is higher, so that the finished board has larger deformation, and is more obvious particularly in high-speed operation, and the quality and the yield of the finished board are greatly influenced.

Fig. 2 is a top view of fig. 1.
Detailed Description
The invention is described in detail below with reference to the drawings and the detailed description.
Referring to fig. 1 and 2, the continuous press for artificial boards with cooling function shown in the figures includes a continuous press 100, which is different from a conventional continuous press except that a cooling section 200 is additionally provided at a board discharging end of the continuous press 100, and the rest of the continuous press is not different from a driven continuous press, and will not be described herein again for brevity.
The artificial board continuous press with the cooling function of the invention is additionally provided with the cooling section 200 at the board outlet end of the continuous press 100, so that the finished board from the heating and pressurizing section 130 is cooled and shaped, and the heat of the finished board is recycled.
The cooling section 200 includes a frame 210, an upper cooling platen 220, a lower cooling platen 230, a plurality of pressurization cylinders 240, an upper chain blanket mechanism 250, a lower chain blanket mechanism 260, and a cooling circulation system 270.
The upper cooling platen 220 is mounted on the frame 210 by a plurality of pressurizing cylinders 240, the cylinder portions of the plurality of pressurizing cylinders 240 are mounted on the frame 210, and the upper cooling platen 220 is mounted on the cores of the plurality of pressurizing cylinders 240. The pressurizing oil cylinder can be a piston cylinder or a plunger cylinder. The specific type and mounting method thereof can be referred to the mounting method of the hot press plate and the pressurizing oil cylinder in the driven continuous press, which should be well known to those skilled in the art.
The lower cooling pressing plate 230 is fixed on the frame 210 and located below the upper cooling pressing plate 220, and a plurality of pressurizing oil cylinders 240 pressurize the upper cooling pressing plate 230 and cooperate with the lower cooling pressing plate 230 to cool and shape the finished plate passing between the upper cooling pressing plate 220 and the lower cooling pressing plate 230. After the finished board is cooled and shaped, the temperature is reduced to the cooling temperature required by the board making process, so that the deformation of the formaldehyde-free finished board can be greatly reduced, the product quality and the yield are improved, and the production of thin boards and ultrathin boards is particularly obvious.
