Description

The invention relates to the production of heat insulating building materials, in particular for lining decorative acoustical mineral wool or glass wool.

 The purpose of the invention is to intensify the process and increase the quality of products.

FIG. I pbkazan installation for cladding fiber products, the general view; in fig. 2 - the same plan view; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section B-B in FIG. one.

The installation for lining mineral wool or glassy fiber products includes a feed conveyor, a coating supply unit for: materials, including coil holders 2 and 3 for finishing material 4 and a plastic film 5. A knotting unit, including heated 6 and cooled 7 plates, and an adjustable Belt in height clamping conveyors 8, arranged in a staggered pattern along the movement of products, a longitudinal and transverse cutting unit 9, heated by a 10 and cooled 11 horizontal-rake skids, top-imii and five-sided ffly legs Anspoter 12 and removable device 13.

The installation works as follows ...

The finishing material 4 and the polymer film 5 are continuously wound from the first roll holders 2 and 3 to the feeding conveyor 1. On top of the film 5 to the feeding conveyor 1-to-. . pieces are laid down, for example, mineral wool plates 14, which, together with the finishing material 4 and the polymer film 5, are supplied; to the heating plate 6 gluing knots. Mineral wool plates 14 with a finishing material 4 and a polymer film 5 (prizhmpm) 1M conveyor 8, which is located on the opposite side of the surface to be coated, are pressed against the heating plate & As a result of contact heating, the polymer film 5 melts; the film melts during the movement of the mineral wool plate 14 along with the release material 4 and the polymer film 5. The temperature of the heating plate 6 and the pressure of the mineral wool plate

14, uniform penetration of the molten polymer material 5 into the pores of the mineral wool plate 14 and the finishing material 4 is achieved,

what provides its high-quality attachment. In addition, in the process of moving the mineral wool plate 14 pressed against the surface of the heating plate 6, an iron effect is created that smoothes the finishing material 4, which makes it possible to obtain a smooth, smooth surface of the veneered mineral wool plate 14. Further mineral wool plates 14

together with the finishing material 4 and the molten polymer film 5 are received. to the cooling plate 7,. and in the process of movement on its surface, deflation of the molten polymer material occurs, which ensures uniform and durable bonding of the finishing material over the entire surface of the mineral wool plate 14. Stepless regulation of the position of the pressure plate

conveyor 8 at the height of security

It does not have the possibility of finishing various types of mineral wool. The finishing of the second surface of the coated ones. The slab occurs when the kx passes through a similar gluing unit, located in a staggered order along the movement of the products.

Mineral-wool plates 14, lined on both sides, go to cutting site 9, where cutting of excess decorative material 4 and polymer film 5 occurs. Further, facing 14 plates go to heated slider m 10, which bend the finishing material 4 hanging from the edges polymer film 5 and press them to the surface of the side

the edges of the plate 14. Next, the passage of the cooling skids 1 1, is the curing of the molten polymer layer and gluing the cladding material. To ensure that the finishing material 4 is evenly pressed against the edges of the mineral wool plate 14, the heated rails 10 are provided with spouting devices 5 to compensate for the spread.

sizes of mineral wool 14 by

width. For the processing of mineral wool slabs of various widths

made sliding. Further, in

31

the second cutting node 9 is transverse cutting facing materials.

Lined mineral wool. The plates are fed to the removable device 13 and are further fed to the packaging and storage.

The application of the proposed installation for cladding mineral wool or glass wool plates provides high-quality finish their surface and edges. By adjusting gluing modes, it can be made lined with 407404

mineral and glass wool slabs with desired properties. At higher temperatures, ensuring complete melting of the polymeric material, the adhesive layer is made porous, which ensures the preservation of the sound-absorbing properties of the base plate. At lower temperatures, only the size of the polymer film occurs, which ensures the preparation of a continuous, non-porous yoke-fiber layer that enhances the vapor impermeability of the product. .
