Description

Double crawler side sealing device

technical field

The device of the invention is applied to the continuous production line of polyurethane and phenolic composite boards. Its function is to precisely match the required geometric shape of the side of the composite board when the side of the composite board is corner-wrapped and leak-proof through roll forming of the side-sealing paper, and finally reduce the amount of trimming on the side of the composite board. The invention belongs to the technical field of composite plate double crawler machine equipment.

Background technique

At present, the side edge banding of composite boards at home and abroad is arc-encapsulated (as shown in Figure 5). In order to obtain regular composite board products (as shown in Figure 6), the arc corners on both sides are cut off after the composite board is solidified and formed. In view of the characteristics of large production capacity and expensive raw materials of polyurethane and phenolic continuous production lines (the annual trimming waste of a production line in ordinary production enterprises is about 1.5 million yuan), the traditional process has caused a huge waste of materials. The appearance of this invention reduces the 20mm trimming amount of the traditional technology to within 2mm, which greatly saves the production cost and reduces the generation of industrial waste products, and fills the gap in this field at home and abroad.

The traditional arc angle wrapping method is to naturally bend the side sealing paper into an arc to wrap the sides of the upper and lower layers. During the foaming reaction of chemical materials, the standard right angle cannot be produced by the foaming tension, so it must rely on the compounding after curing. The sides of the board are cut to obtain standard geometries.
