Changzhou Longkai Machinery specializes in manufacturing a complete set of production line for exterior wall insulation and decorative panels
One, wall panels Introduction
Metal engraved exterior wall panels Continuous Production Line is a decorative wall panels based on production of new environmentally friendly lightweight building materials, polyurethane foam, which is currently popular in the international market. It can produce fire-retardant, flame-retardant, heat-insulating and decorative wall panels with steel plate on the surface, polyurethane in the middle and aluminum foil or steel plate on the bottom. The main application scope of the product: the old building appearance transformation, high-grade villa apartment, villa, hotel, light steel structure, mobile house, farmhouse, large shopping malls, factory interior and exterior walls, and so on.
Two, equipment composition
Composite polyurethane insulation board continuous production line is mainly unwinding machine → embossing machine → calibrating machine → side molding machine → heated platform → AB material foaming machine injection → aluminum chain plate laminating machine → sawing board cut off → coloring → packaging and other components.

Four, polyurethane insulation composite board continuous production line unit machine structure and function introduction
Ⅰ. Unwinding machine
Function: used for unloading embossing of steel coil.
Structural form: welded steel frame, through the hydraulic cylinder to achieve lateral displacement, to prevent the coil from running off, uncoiling passive type, with pneumatic brake to achieve tension control.
II. Embossing machine
Function: According to different flower color wall panels, use the upper and lower two pairs of pressure relief metal flower rollers to press out different patterns of color steel.
III. Foaming machine:
BLC(R) type low-pressure continuous foaming machine or PH(R/F) high-pressure foaming machine, adopting one resin (A) material tank and one hardener (B) material tank; two metering pump units are driven by independent frequency conversion motors, and the output flow rate of the metering pumps is controlled by changing the rotation speed of the metering pumps. Finally, the components are mixed according to the required ratio and evenly sprayed between the lower steel plate or other substrates.
Ⅳ, molding machine
Function: to emboss the color steel for many rounds of folding shape processing.
V, laminating machine
Function: to complete the polyurethane online foaming and shaping; chain plate unit consists of driving motor, sprocket, aluminum alloy chain plate, pin and rolling bearings. Adopting electric heat pipe heating; it can quickly heat the double belt machine to the temperature needed for production. When the temperature reaches the preset value, you can choose to turn on or off the electric heating during the normal operation of the production line according to the needs of the actual situation.
VI.Sawing and Cutting Machine
Function: Saw off the molded sheet according to the set size.
Structure: the machine base, machine body and upper moving frame are made of section steel and plate welding structure, which are connected together by linear guide rail, and the mounting surface of the guide rail has been finely machined to ensure the mounting precision; the sawing motor is mounted on the upper moving frame, and the moving frame is driven by the speed reducer motor to move horizontally; the clamping device is mounted on the machine body, and it consists of a cylinder and a pressurized block; the reset device consists of a cylinder and buffer; when the plate reaches the set length, the clamping device is mounted on the machine body, and it is driven by the speed reducer motor to move horizontally. When the plate reaches the set length, the clamping cylinder pushes down the clamping block, and the reset cylinder pushes the machine body to move along with the plate; at the same time, the sawing motor starts, and the geared motor drives the upper moving frame to move transversely, so as to realize the transverse cutting of the plate; after cutting off the plate, the clamping device lifts up, and the reset cylinder pushes the machine body to return to the origin and reset.
Five, polyurethane insulation composite board continuous production line automation control
Automation control system is divided into uncoiling embossing area control, molding laminating area control, foam area control and sawing area control of the four parts of the total power of about 60KW; which the heating platform about 30KW. the whole set of control system can be programmed controller, detection switch, Delta frequency converter drive. Detection switch, Delta inverter driver and other components, through the touch screen parameter input and button with the operation, to realize the automatic production line, its performance is reliable and stable, easy to operate.
