Polyurethane foam sandwich panels are produced on a continuous production line, the lower layer is a soft material such as nonwoven fabric, middle interlayer of polyurethane sandwich board special equipment, the specifications of the sandwich plate with a thickness of 20 - 90 mm, a width of 1200 mm, the length of the self - identification.The operation principle is as follows:Polyurethane foam stock solution by the metering pump of the filling machine in a definite proportion is fed into the mixing head are mixed uniformly cast sandwich plate in a bottom surface of said circuit, and on the dimensions and material into the laminating conveyor, in the laminated above and below the conveyor chain between the foamed and cured to form; and curing material because of the production line after forming of the sandwich on both sides after trimming is automatically tracking cutter according to the required cut - to - length product

The equipment consists of
& nbsp; & nbsp; & nbsp; & nbsp; & nbsp; This line 由放料 device sets, 面材预 heating device set, a low pressure PU foaming machine, the direction of the movement of a machine, 1 set of 贴侧 paper, laminated to a hot - air circulating device set, a set of the trimming device, automatic tracking cutter machine, the roller frame, etc.
The four major equipment upgrades.
1. was used instead of plastic stoppers and aluminum stoppers, using self - developed 120 mm thick 铝挡 block, in the production of various specifications of the thickness of the sheet without the replacement block, and to save a set of 贴侧 paper device, to a great extent on the coating.
2, was used instead of the hydraulic lifting system, has been losing high screw elevator system, reduction in the total system power, thereby reducing the energy consumption of the elevator system to function more smoothly, freely, lifting size more precisely, in order to overcome the pressure of the hydraulic system unstable, inconsistent, so as to achieve simple operation, easy maintenance, easy maintenance.
3. materials was used instead of the above arrangement, there are two unreeling devices are placed on the ground, so as to solve the problem of workshop of no service, and more easily to a reel, and the operation is more convenient, reduces the use of the investment cost.
4, uses a new type of adjustable double mitre saw blade, so as to reach 900 mm, 1200 mm, 1800 mm and 2400 mm - four arbitrary adjustable length specification
