Description

technical field [0001] The invention relates to the field of composite plate production equipment, and more specifically relates to a composite plate production process and production equipment. Background technique [0002] The existing composite process can only use polyethylene polymer film for high-temperature and high-pressure composite bonding of the core material. The composite core material is limited to high-pressure polyethylene, but the use of corona treatment and the corresponding adhesive can effectively treat PVC. , PVC foam board, PP, PP foam board, polyethylene and other core materials for bonding. In the original aluminum-plastic panel composite process, the polyethylene core plate is calendered by the three-roller machine, and the upper and lower aluminum coils are directly fed into the five-roller precision press unit for high-temperature and high-pressure compounding. The existing production process of using polyethylene polymer film for high temperature...

Therefore, the addition of a cooling system increases the length of the production line and also increases energy consumption

[0005] 3. Although the deformation of the composite sheet caused by the release of internal stress has been greatly reduced by adding a cooling system, there are still a certain number of sheets that are deformed due to the slow release of internal stress within a certain period of time after production. After the leveling process, some parts can be used after straightening, while the other parts cannot be straightened and can only be scrapped, which also caused great losses.

[0006] 4. Due to the limitation of screw discharge volume and cooling time, the production rate of the original production line is very slow, and the production line speed is generally maintained at 3 m / min to 5 m / min. The energy consumption is huge but it is not proportional to the output. Proportional
