Description

The invention relates to the building materials industry and can be used in the manufacture of a substrate of fibrous materials.

The purpose of the invention is to increase the durability of the mat used for the substrate when growing plants by increasing its quality.

1 shows a schematic flow line, side view; Fig. 2 is an axial pressing device, front view; on fig.Z - tsection Ј-D, in figure 2.

The punchline for the production of a fiber piercing mat contains a fiber deposition chamber 1, a feeding conveyor 2, a feeding fiber carpet 3. a mechanism 4 winding fiberglass canvas from a coil 5, feeding rolls 6. a corrugator 7, an axial pressing device 8, a piercing machine 9, unit 10 cutting the carpet 11 into mats of the required size and unloading conveyor 12..

The axial pressing device contains two pairs of bevel gears 13 mounted on the shaft 1F and, "fixed on the screws 15, the screws interact with the nuts 16 connected by a bracket (not shown) with the shaft of the upper axles | yugwealka 17.

In order to increase the adhesion of the main 17 and additional 18 rollers to the fiber carpet 11, they are made grooved with hollows and protrusions on the surface. In order not to destroy the main surfaces of the mat, the corners of the corrugations are rounded,

The operation of the device is carried out in the following sequence. ,

The fiber carpet 3 formed in the fiber deposition chamber 1 is supplied by the conveyor 2 to the feed rolls 6. A glass fiber canvas 4 coming from the winding mechanism 4 is fixed between the carpet 3 and the feeding rollers 6. The winding mechanism operates due to the constant contact of the bay with the glass fiber canvas mineral wool basis for its movement. A constant contact is provided by the weight of the coil fixed to a freely rotating shaft (not shown). A carpet, covered at the top and bottom or at least on one side with a glass fiber canvas, is calibrated and fed for shirring. By the mass pipeline of the corrugator 7, the carpet is fed into the device 8 for axial pressing, in which, after repeated axial compaction and acquiring the required density, is fed to the piercing machine 9. The finished fiber carpet 11 is cut into mats of the required dimensions in unit 10,

having knives for longitudinal and transverse cutting.

Example. Mineral wool carpet 2 m wide and 150 mm thick with a density of 30

kg / s3 with a hydrophilic substance introduced into it, formed in the fiber deposition chamber 1, is delivered at a speed of 4 m / min to the feed rolls 6. On the main surfaces of the carpet from above and below and between

0 feed rolls 6 are applied layers of fiberglass canvas, coming from the winding mechanism 4. The carpet, together with the fiberglass layers of the canvas, is calibrated to a thickness of 30 mm and is fed to the corrugator 7, where it is crimped together. The creased carpet has a thickness of 60 mm and a density of 75 kg / m. In order to avoid accidental clogging of the mass pipeline with a corrugated carpet, the first pair of shafts of the axial pressing device 8 has a linear speed equal to the speed of the carpet taken from the corrugation unit of 3.3 m / min. The second and third pairs of rolls have speeds of 1.2 times less than

5 of the first and second pairs, respectively, i.e. the speed of the second pair is 2.75 m / min, the third is 2.3 m / min. Accordingly, as the speed changes, the density of the carpet changes. The density of the carpet after the second pair of rolls

0 90 kg / m3, after the third 103 kg / m3. At this speed, the carpet is fed to the piercing machine 9 and to the node 10 of cutting the carpet 11 to mats having a length and width of 1000x1000 mm.

5 To change the vertical distance between the rollers, the handwheel 19 rotates the shaft 14 and two pairs of bevel gears 13, transmitting movement to the screws 15. Screws 15, rotating, raise or lower the nuts

0 16. connected by means of a bracket (not shown) with the shaft of the upper pressing roll 17. Thus, the horizontal and vertical distances between the main and additional rollers are adjusted.

5 The use of the invention allows to obtain the specified density of the substrate in a large range of 50-300 kg / m and more. At the same time, there is no clogging of the corrugated carpet during transmission.

0 carpet from one node to another, it is possible to obtain products with a greater degree of corrugation, which significantly increases the strength of products and, ultimately, increases their durability.
