WS1000 polyurethane/rock wool composite board automatic integrated production line is an automatic equipment for producing polyurethane/rock wool composite board. The equipment integrates an automatic production line with the functions of uncoiling, laminating machine cutting, forming rock wool, preheating, foaming, curing, cutting, cooling, stacking, packaging, etc. The whole line combines mechanical, chemical, electronic control, hydraulic, Pneumatic and temperature control technologies.

　　Main components:

Uncoiler: usually single-station, manual centering, section steel welding frame, lateral displacement through thread nut to prevent coil deviation, uncoiling adopts passive type, and pneumatic brake to realize tension control.

Tension control device: air inflation control, easy to operate, used to control the tension of the coil.

Preheating unpowered roller table: used for conveying the lower supporting material, heating the metal coil, aluminum foil, glass fiber cloth, non-woven fabric, welding frame, unpowered roller, with protective heating device and temperature control device.

Foaming machine: such as BLC(R) type low-pressure continuous foaming machine or PH(R/F) high-pressure foaming machine, using resin (A) tank and curing agent (B) tank, through two metering pump units are respectively driven by independent frequency conversion motor, according to the required proportion of mixing components and evenly sprayed between the lower steel plate or other substrates.

Mobile cloth machine: realize the uniform arrangement of various core materials. The main frame is installed on the base, the distance between the cloth machine and the double belt machine is adjustable, and the height can be adjusted by the adjustment device on the base.

Upper uncoiler platform: used to support the upper layer uncoiler, section steel welding structure, with guide roller device.

Press machine: metal coil for a variety of shape processing.

Double crawler: complete polyurethane online foaming and shaping, including the fuselage, chain plate unit, lifting unit, insulation unit and other parts. The fuselage is used for installation and positioning of each part; the chain plate unit carries the core material and ensures its foaming and shaping to ensure the flatness and thickness consistency of the surface of the plate; the lifting unit adjusts the thickness of the plate and supports the upper and lower fuselage; the heat preservation unit provides heat source to ensure the foaming temperature and consistency of the core material.

Unpowered roller table: after the double belt machine, it is used for plate cooling and shaping, steel welding structure, unpowered roller.

Fixed-length sawing machine: sawing the formed plate according to the set size. The machine base, fuselage and upper moving frame adopt section steel and plate welding structure. The sawing motor is installed on the upper moving frame and is driven to move laterally by a deceleration motor. The clamping device and reset device are composed of a cylinder and related components.

Working principle: The production line realizes the automatic production of polyurethane/rock wool composite board through the cooperative work of various links. First, the uncoiler unrolls the coil and maintains an appropriate tension through the tension control device, and the preheating unpowered roller table preheats the substrate. Then, the foaming machine mixes the polyurethane raw materials according to a certain proportion and evenly sprays them on the substrate, and the mobile cloth machine evenly arranges the core materials such as rock wool on the polyurethane. Next, the board enters the double track machine, in which the foaming and setting of the polyurethane are completed to form the composite board. After cooling and shaping without power roller table, the fixed-length sawing machine saws the composite board according to the set size to obtain the final product.

     Product performance characteristics

1. The composite board produced by this production line is beautiful and practical, with heat insulation, sound insulation, flame retardant and other functions.

2. The production line uses a hot air circulating heating furnace to foam the polyurethane, and the curing temperature is strictly controlled within the specified range to ensure a high quality composite board.

3. The high-pressure foaming system used in the production line has accurate measurement, high stability, and less floating particles in the field environment, ensuring the health of personnel.

4. The double track system is adopted to solve the polygon effect, so that the layout of the composite board is flat, the thickness is uniform, and it is not easy to deform.

5. Strong expansibility of the production line: unit equipment such as cool plate, palletizing and packing are added at the rear, which can fully automatically produce various sandwich plates such as double-sided color plate sandwich plate, color plate and soft-sided sandwich plate.

6. The production line adopts European technology design, with high degree of intelligence, low cost, high rigidity, precision and stability of the equipment, and simple and convenient operation.
