Machines： The rock wool PU edge-sealed color steel sandwich panel production line is mainly composed of an uncoiling system, a film-coated cutting and pressing rib, a molding machine system, a rock wool automatic feeding system, a two-component low-pressure side foaming system, and upper and lower rock wool spray glue system, double-belt laminating machine, double-belt heating system, cutting system, stacking system, packing system and other equipment. Project consition： Output ：80～1000000㎡ Whole line length：about 120 m Double-belt effective length: 24 m Labors：6-8 Heating method ：electricity Project background： The client of this project specializes in the production of rock wool PU edge banded color steel sandwich panels. With the rapid development of modern urban construction and the rise of industrialized workshops and other buildings, steel structure buildings have been widely used in various urban buildings, office buildings, various modern industrial plants and civil buildings and other fields. With the rapid growth of demand for roof panel materials, rock wool PU edge-sealed composite panels are a new generation of decorative wall enclosure materials and roof panel materials, and are the most popular new generation steel structure building materials. It has the function of enclosure and thermal insulation, and also has the role of decoration. It is the only new wall building material that can integrate enclosure, decoration and thermal insulation. The traditional production line equipment has a low degree of automation, high labor costs, very low product accuracy and equipment quality, and low production efficiency. After many inspections, the customer decided to invest in the fully automatic rock wool PU edge banding color steel sandwich panel of Zhongji Machinery. The production line runs well after it is put into production, and the output is stable, which has brought huge economic benefits to customers. Project advantage： The production line adopts domestic and foreign advanced roll forming technology, HCFC polyurethane foaming technology, composite conveying technology, numerical control servo control technology, frequency conversion vector control technology and hydraulic control technology. The entire line requires only six to eight operators to operate normally. The characteristics of this production line are: high degree of automation, fast production efficiency, simple operation, low production cost and saving investment cost.
