Description

Technical Field

[0001] The invention relates to the technical field of polyurethane foam board production, and in particular to automatic production equipment and method for polyurethane foam boards. Background Art

[0002] Polyurethane foam board is a new synthetic material with thermal insulation and waterproof functions. Due to its low thermal conductivity, it is mainly used in building exterior wall insulation, cold storage insulation, pipeline insulation, building panels, refrigerated trucks and cold storage insulation materials, etc. When producing polyurethane foam board, firstly, black material and white material need to be injected into the foaming machine for mixing to obtain foaming raw materials, which are then sent to the surface material moving at a uniform speed for foaming. At the same time, the upper surface material is combined with the foam plastic to finally obtain a polyurethane foam composite board with surface materials on both the upper and lower sides. Most of the materials used as surface materials are aluminum foil and metal materials. During the foaming and transmission process, the polyurethane foam is matured in the double-layer pressurized panel. After that, the board only needs to be cut into the required length to produce the polyurethane foam composite board of the required specifications. During production, foam boards of different thicknesses need to be manufactured according to demand, so the distance between the two surface materials needs to be adjusted. At the same time, after the foam board is produced, it needs to be trimmed, and the excess surface material of the initially matched part needs to be trimmed, which causes great waste. Therefore, we propose an automatic production device and method for polyurethane foam boards. Summary of the invention

Then the two aluminum plates are combined, and the foaming material expands and solidifies, completing the production of the foam board. With the transportation of the conveying mechanism, the foam board is continuously formed to complete the automatic production of the polyurethane foam board. Since the bent pipe is bent to the side close to the lifting component, that is, it is bent close to the position of the two aluminum plates, the foaming material is poured into the interval between the two aluminum plates as much as possible.
