Structure: welding steel rack, wire mother lateral displacement, to prevent roll material deviation, uncoiling the passive type, pneumatic brake tension control. 1.2, tension control device: gas up control, simple operation. 2, preheat the powered roller function: double with machine conveyor used to lower child care, as well as the metal coil, aluminum foil, glass fiber cloth, non-woven heating structure: welding rack, unpowered roller belt protection heating and temperature control devices. 3, foam machines: PF-1-type low-pressure continuous foaming machine or a high pressure foaming machine, using a resin (A) feed tank, the feed tank of a curing agent (B); two metering pump unit were used to separate variable frequency motor drive, controlled by changing the speed of the metering pump metering pump output flow. Finally each group required proportion are mixed and uniformly sprayed between the lower steel plate or other substrate. 4, mobile fabric machine function: uniform layout structure of raw materials to achieve a variety of core materials: the main frame is mounted on the base. The distance between the the fabric machine with machine adjustable base regulating device is equipped with adjustable height. 5, the upper uncoiler platform functionality: uncoiler used to support the above layer structure: welding steel structure, with a guide roller device; 6, roll forming machine functions: processing various metal coil shape. 7, the dual track machine function: complete online polyurethane foam and stereotyped; wherein the fuselage for the unit of the chain plate, lifting the part of the installation and positioning of the unit, holding unit, etc.; chain plate unit for the hair of the carrier core material and the core material bulbs and styling, to ensure the consistency of the flatness and thickness of the plate surface; lift unit for adjusting the plate thickness and the supporting body of the lower portion; insulation unit is used to provide heat to the unit and the body of the chain plate, ensure and maintain the temperature of the core material foam to ensure the consistency of the foam core material; structure: Rack and nose using H-shaped steel plate welded structure CNC machining equipment has been a fixture positioning processing, ensure that all the critical dimensions and The installation accuracy; the rail board CrlZ plate, quenched after grinding to ensure its dimensional accuracy and surface finish, install the rack on the next plane to ensure smooth and reliable operation of the chain plate unit; chain plate unit by the drive motor, chain wheel, crawler plate, a chain block, the pin and Rolling. K series high precision hardened gear motor, smooth and reliable operation; shoe plates welded profiles and sheet to stress treatment after welding, machining CNC machining equipment, to ensure that the size and shape accuracy. The chain block consists of a welded steel plate, welding after removal of the stress, machined to ensure that all the critical dimensions. Lifting unit, the precision hydraulic lifts drive on the fuselage mobile that can serve as a guide supporting role, and can fine adjustment. Insulation unit form of a framework, the framework of the main profiles and sheet production, various components are used bolt connection without welding work on-site with easy disassembly, reducing the labor intensity of the on-site construction. Insulation block box-shaped structure of steel production, which filled glass fiber cotton, good insulation properties, less heat loss. Electric tube with the fuel furnace heating. Double belt machine can quickly heated to the temperature of the production needs. When the temperature reaches a preset value, according to the actual needs of the situation, the normal operation of the production line, select to turn on or off the electric heating. 7, powered roller features: dual-band machine for sheet metal cooling stereotypes. Structure: welding steel structure, unpowered roller. 8, cut to length sawing machine: molding plate in accordance with the set size amputated. Structure: base, body and move the frame made of steel and plate welded structure, with a linear guide connection rail mounting surface finishing, ensure the accuracy of the installation; sawing motor is mounted in the upper part of the mobile shelves, mobile rack by deceleration motor drive, transverse movement; clamping device is mounted in the machine body, and is composed of a cylinder and the pressing block; reset means by the cylinder and the buffer means; when the sheet reaches the set length, the clamp cylinder to push clamping block depressed, the reset cylinder promote the body to move together with the plate; sawing motor start, gear motor driven upper mobile the frame lateral movement, plate transection; cutting is completed, the clamping device to lift and reset the cylinder to drive the body to return to the origin reset . Fifth, the advantages of the product, extended performance: rear increase the dry plate, palletizing, packaging unit, can be fully automated production of sided color plates sandwich panels, color plates and soft surface layer sandwich panels, soft surface layer sandwich panels and other types of sandwich panel; technical advantages: the entire production line using the European technical information design, technological innovation, reduce costs, especially for the newly launched company. Device stiffness, high strength, accuracy, stability; 3, the entire electrical control leading international system, reliable operation, low failure rate; 1, the flatness of the finished sheet, uniform density core material; automation control automation control The system is divided into the uncoiling regional control, The double belt molding machine area control and cold plate sawing regional control of three parts, with a total power of about 120KW; heating platform approximately 50KW.
