Description

one

The invention relates to the textile industry, in particular to the production of nonwoven materials from warp and weft.

A known apparatus for producing a nonwoven material from warp and weft, comprising a multi-storey core, guides for warp and weft threads, a warp spool for warp threads, a spool reel for weft threads, made in the form of a rotor with bobbins, a drive for moving warp threads and a weft, glueing shchey, substantial and winding device, knife adaptation 1.

In this installation, the guides of the warp and weft threads are made in the form of endless cables with outer braid located in the corners of the polyhedron. Such a structure does not ensure uninterrupted operation of the installation, since under the action of a constant load the cables are pulled out (their lock joints are broken), and the braid from constant friction on the polyhedron quickly collapses, which ultimately leads to frequent stops to replace the damaged cables.

The purpose of the invention is to increase plant productivity.

The goal is achieved by the fact that each guide of the warp and weft threads consists of closed chains and hollow cylindrical elements fixed to chains with X-shaped brackets, while the end surfaces of each cylindrical element are inclined relative to its longitudinal axis at an angle 45 °.

FIG. 1 shows the proposed installation, a general view (without a front drum and a miner); in fig. 2 shows section A-A in FIG. one; in fig. 3 is a diagram of the movement of the warp and weft threads; in fig. 4 - closed circuit element; in fig. 5 is a view along arrow B in FIG. four; in fig. 6 - section

B-B in FIG. five; in fig. 7 - rotor clamping device; in fig. 8 - section G-Y in FIG. 7

The installation contains a three-story metal structure 1, on the first floor

which has a ventilation device 2, and on the second floor there are drying devices 3, devices 4 for winding finished material, devices 5 for trimming the fringe and pull devices 6. These

The devices are connected to the camshaft 7 chain drives 8. Adjustable couplings in the winding devices provide a constant tensioning of the winding material. On the second floor also

drive 9 is installed moving the threads

bases and an adhesive application device 10. In the corners of the polyhedron 11, special guides 12 are installed along which the closed chains 13 move with the cylindrical elements 15 which are inclined at 45 ° fixed to them by means of X-shaped brackets 14. The knives 16 are also located here, which serve to cut the wound material into flat webs according to the number of sides of the winding.

The third floor is a service platform 17, on which is placed the spool of weft threads, made in the form of a rotating rotor 18, covering the winding polyhedron. The rotor has 19 quick-detachable spider-holders 19 weft threads and a yarn break alarm mechanism, which consists of an annular current collector 20, fixed brushes 21, individual sensors 22, plug connector 23 and light signaling 24. The rotor is exposed on rollers and receives rotation through a gear. On the third floor there are 25 warp threads, thread guides 26 and a rotor drive.

The installation works as follows.

From the cores 25, the warp threads from four sides (by the number of winding faces) through the thread guides 26, which distribute all the threads in the planes between the pairs of chains, are directed to the winding devices 4.

The size of the gaps between the threads in the yarn ducts depends on the required structure of the material.

The polyhedron formed by a combination of all the chains is wrapped with weft yarns, which are wound from shpulya installed in the spider holders 19 on the rotating rotor 18. As a result, four mesh webs are formed by weft yarns interconnected by transverse yarns that move

cylindrical elements 15, fixed on closed chains 13, to drying devices (drums) 3. Upon contact of the webs with the essential drums 3, the transverse threads are clamped at the edges of each web between the flexible elements 27 and the surface of the drum, and the webs are separated by cutting the joints their transverse yarns with knives 16. An adhesive is applied to the canvas by the device 10. The passage around the drum 3, the web dries, the duck is connected to the base, and is wound on a sleeve installed in the device 4.

Thus, the proposed installation can significantly improve performance.
