3 3 non-continuous polyurethane laminating machine

The laminated mold greatly reduces the labor intensity of workers, saves labor time and improves production efficiency. The equipment occupies a reduced area and reduces capital investment. This equipment adopts contact heater, which can set the preheating time and automatically disconnect the power supply during the operation of workers, which is safe and reliable. This equipment adopts the left and right rotation pressing, the left mold in the pressing process, the workers operate the right mold, when the right mold for pressing, assembling the left mold, a cycle of time greatly improve the work efficiency. The hydraulic system of this equipment is self-starting and self-rest, which can save energy consumption better. Equipped with 7-inch touch screen, man-machine interface, simple operation.

Non-continuous polyurethane laminating machine

The discontinuous line is used for the production of PU sheets. Different from the continuous line, the discontinuous line uses a single-block production mode. Although the production capacity is not as good as the continuous line, the discontinuous line is relatively flexible. It is suitable for small batch orders and some orders with large width and small quantity. It is also suitable for matching with the continuous line in cold storage production to cover various order requirements. Type 2 continuous line produces 2 plates at a time, and simultaneously loads and unloads the other two plates during pressure keeping, which improves efficiency.

Hinge type laminating machine

Polyurethane composite plate hinge laminator is a new generation of intermittent composite plate production line launched by WEIHUA company, which can produce PIR high flame retardant polyurethane composite plate, which is not achieved by the original injection process laminator. The equipment has good flexibility, fast switching performance of various specifications, can be fully suitable for small batch production of many varieties, the use of small sites, with good flexibility, less initial investment, this product is very suitable for intermittent mass production. The production line has been successfully applied to Shandong Wucheng Company. After two years of production test, it has obtained very good results and verified all the original ideas through practice.

Continuous polyurethane sandwich panel production line

After 15 years of hard work, Wuxi WEIHUA Machinery Co., Ltd. has completed the overall production of polyurethane sandwich panel production line by itself and obtained a number of patents. Among them, the foaming machine and flat polyurethane panel are the leaders in this field. WEIHUA not only has cold roll forming technology, but also has foaming technology and rock wool whole line technology. The key technology of the foaming system inherits the advanced technology of European manufacturers, and the mirror flat sandwich panel is the leader in this field. The whole PU & rock wool sandwich panel production line includes: uncoiler, steel panel lifting device, shooting and cutting equipment, ribbing equipment, main forming machine, steel panel connecting device, steel guard plate preheating equipment, rock wool system, high pressure foaming machine, side sealing device, double belt conveyor machine, heating device of double belt conveyor, automatic tracking band saw, output roller path, panel cooling system, automatic stacker, packaging machine, etc.

Rock wool system

The rock wool system is to change the fiber direction (horizontal into vertical silk) by slitting, transporting and turning the large pieces of rock wool with horizontal tiling fibers, so as to increase the bearing strength of the finished rock wool composite board, so as to meet the requirements of the strength of the building composite board. Then the rock wool strips are reasonably arranged cross each other to avoid the weak link of fault concentration in the longitudinal butt joint of the rock wool strips, and a high-strength composite board product is obtained. The arranged rock wool strips are cut, milled on the lap surface, sprayed with upper and lower rock wool, and finally bonded and solidified with upper and lower color steel plates, glass fiber cloth, calcium silicate board and other materials to form an integral composite board. Rock wool is composed of storage hoist, rock wool slitting machine, steering conveyor, plate copying and turning vertical silk machine, rock wool typesetting and feeding machine, edge milling machine, rock wool glue spraying machine, dust suction machine and other equipment.

Soft surface layer system

In July 2012, our company provided a full set of soft surface composite board production line to Nanjing Hongbaoli Co., Ltd. The production line applies a number of WEIHUA patented technologies, mainly including side edge sealing technology during the production of soft surface insulation board, upper and lower surface material correction detection technology, continuous production surface material docking technology, and energy-saving technology of double crawler. At present, the precision of the composite plate out crawler before trimming can reach 1203mm. According to the output of two shifts, 1.5 million of polyurethane raw materials can be saved every year, while the special crawler insulation system can save 30% of energy consumption for users.

Pentane storage system

The pentane storage and conveying system is mainly used to store cyclopentane unloaded from the tanker and automatically feed the foaming machine. Because pentane vapor is flammable and explosive, the system must be strictly in accordance with the relevant standards. The pentane storage system includes: tank body, pentane delivery system, tank body breathing system, liquid level system, unloading system and pentane detection system. Technical parameters: Tank volume: 35m ³ Tank type: double tank Interlayer medium: ethylene glycol Delivery pump: red jacket submersible pump Quantity of delivery pump: 2 sets (one for standby and one for use) Pentane detector: Messien or Derg Energy: electricity, three-phase five-wire system, 380 volts, error 10%; Compressed air, 6-8bar, nitrogen 6-8bar. Ground stud (less than 2 ohms) Lightning protection facilities Foundation (drawings provided by the Supplier) Fire protection system

Rock wool storage material lifting

Rock wool storage hoist is to meet the continuous production of rock wool automatic continuous feeding machine.

Soft surface layer uncoiler tightening and storage docking and correction device

The uncoiling and storage of soft surface layer is one of the core parts of the production line, which can smoothly uncoiling soft surface materials such as kraft paper, cement mortar cloth and aluminum foil for crawler curing and compounding. The core point is to solve the problem of centering and correcting the deviation of the upper and lower surface layers, so that the upper and lower surface layers do not deviate and are controlled at an accuracy of 2mm, thus laying a foundation for greatly saving raw materials for the sealing materials on the curing side of the crawler.
