Description

The invention relates to the production of nonwoven materials, mainly to the production of nonwoven materials by the method of hydro-entangling fibers with high-pressure jets of liquid, such as water.

A known installation for the production of non-woven materials bonded by the method of fiber hydro-entangling (spunlaze method), comprising a bed, a material storage device, a perforated flexible belt conveyor, a conveyor drive, a nozzle device with high-pressure liquid supply means, a nozzle mounting device mounted on the bed with the possibility of impact on fibrous material placed on a perforated flexible conveyor belt, means for removing excess liquid with a pallet, mater separator ala from the grid and the platen roller (see. № Canadian Patent CA 841938 A PROCESS FOR PRODUCING A NONWOVEN WEB, applicant E.I. DU FONT DE NEMOURS AND COMPANY, publ. 19.05.1970).

The known installation has limited capabilities, since the attachment device of the nozzle device placed on the bed with the possibility of impact on the fibrous material does not have the ability to move, and the material storage device does not have the ability to reverse the movement and revolution of the material.

A known installation for processing materials containing a bed, two storage media, a perforated flexible belt conveyor, conveyor drive, fluid supply means placed on the bed with the possibility of impact on the fibrous material placed on a perforated flexible belt conveyor, means for removing excess liquid with a pallet, separator material from the mesh and the support roller (see UK patent No. GB 924348 A Improvements in and relating to the treatment of tricot tubular fabric, applicant FLEISSNER & CO., GMBH, publ. 04.24.1963). In this case, the material stores are box-shaped. Speed, productivity, output are suitably controlled by a stepless drive, which can be obtained by known mechanical hydraulic or pneumatic means. The purpose and means of processing are described in a limited amount, which does not allow to fully describe the installation capabilities.

A known installation for the production of non-woven materials bonded by hydro-entangling fibers (spunlaze method), comprising a bed, two storage media, a perforated flexible conveyor belt and two storage endless conveyor belt, conveyor drive, nozzle device with means for supplying high pressure liquid; a nozzle attachment device mounted on the bed with the possibility of acting on a fibrous material placed on a perforated flexible conveyor belt; means for removing excess liquid with a tray, a separator of material from the mesh and a support roller (see RF patent No. RU 2364668 C2 "Non-woven material bonded with fiber hydro-entangling, and a method for manufacturing such a material", applicant SKA Hygin Products AB (publ. 20.08) .2009). The insufficiently described arrangement of the parts of the installation for the production of nonwoven materials does not allow to fully describe all the properties of the installation.

An object of the invention is to expand the arsenal of tools and functionality with minimal tools used.

The technical problem is solved in that the installation for the production of nonwoven materials containing a bed, two storage media, a perforated flexible belt conveyor and two storage belt conveyor, conveyor drive, nozzle device with means for supplying high pressure liquid, nozzle mounting device mounted on the bed with the possibility of exposure to the fibrous material placed on a perforated flexible belt conveyor; means for removing excess liquid with a pallet, a separator of material from the perforated tape and a support roller, while the material stores are configured to rotate and turn over the accumulated material, the perforated flexible belt conveyor, its drive and two conveyor belt drives are made with the possibility of reverse movement, nozzle attachment device devices made with the possibility of spatial movement and movement of the nozzle device, and the separator of the material from the grid and the support roller with the ability to separate the material from the perforated conveyor belt in any direction of its movement after passing through the nozzle device. The material accumulator is made in the form of a drum mounted on a pallet with the possibility of rotation and inversion of the axis of rotation of the drum with the material, or the material accumulator is made in the form of a box-type accumulator installed with the possibility of rotation and revolution of the material.

A conveyor belt of limited length simplifies the process of replacing it, for example, if different perforations are required, it greatly simplifies and reduces the cost of replacing the belt during operation, since it does not require the installation of an expensive seamless endless belt and disassembly of its drive.

Installation, in which at least one drive material is made in the form of a drum mounted on a pallet with the possibility of rotation and flipping the axis of rotation of the drum with the material, which speeds up and simplifies the process of multiple and multilateral processing of the material.

Installation, in which at least one material is made in the form of a box-shaped drive installed with the possibility of rotation and revolution of the material, which allows to expand the variety of processed materials and to simplify the work of multiple processing of non-woven material.

The proposed invention is illustrated by graphic materials:

figure 1 shows a longitudinal section of an installation with a drum drive;

figure 2 shows a cross section of the installation with drum drives along the line aa of figure 1;

figure 3 is a partial longitudinal section through the installation of the separator material made in the form of a thin wire.

The apparatus for producing non-woven materials bonded by hydro-entangling fibers (spunlace method) comprises a frame 1, two material stores 2 and 3, a perforated flexible belt conveyor 4 and two drives 5 and 6 of a perforated belt conveyor 4, a drive 7 of the conveyor 4, a nozzle device 8 with means 9 for supplying high-pressure liquid, the device 10 for fixing the nozzle device 8, placed on the bed 1 with the possibility of affecting the fibrous material placed on a perforated flexible belt conveyor 4, means 11 Allenia excess fluid with a pallet 12, the separator 13 of the material from the perforated tape 14 and the support roller 15. In this case, the drives 2 and 3 of the tape material 16 are made with the possibility of rotation and reversal of the accumulated material, for example, using known quick-disconnect connections of drum storage media (see Figure 1) and devices for their installation on the frame 1.

This allows you to change the side of the impact on the material through the nozzle device 8 of the means 9 for supplying high pressure liquid. Changing the speed of movement of the material allows you to change the intensity and depth of the impact on the material of the liquid from the nozzle device 8. Means of supplying high-pressure liquid can be any, for example plunger pumps with liquid preparation devices.

When the perforated flexible belt conveyor 4, its drive 7 and two drives 5 and 6 of the conveyor belt 4 are made with the possibility of reverse movement of the material, this allows for multiple processing of the material, and taking into account the possibility of turning the material together with its drives 2 and 3 allows you to change the side of exposure on the material of the nozzle device 8 with means 9 for supplying high-pressure liquid and to increase the uniformity of impact on the material in thickness. When the device 10 for fixing the nozzle device 8 is configured to spatially move and move the nozzle device 8, this allows you to change the depth and intensity of the effect of liquid on the material, to achieve and determine the experimental effect and result, for example, to create a pattern on the surface of the material. The separator 13 of material from the mesh belt of the conveyor 4 and the support roller provides the ability to separate the material from the mesh belt of the conveyor in any direction of movement after passing the nozzle device 8.

An installation in which at least one material storage device 2 or 3 is made in the form of a drum mounted on a pallet with the possibility of rotation and inversion of the axis of rotation of the drum with the material, for example using quick disconnect connections, allows to simplify the work with the processed material and accelerate preparation for subsequent processing steps.

Installation, in which at least one drive material 2 or 3 is made in the form of a box-shaped drive, for example, as is done in an analogue (see UK patent No. GB 924348), installed with the possibility of rotation and revolution of the material, allows to simplify and facilitate work with tape material.

Installation for non-woven materials works as follows.

Before starting work, a tape is prepared from the fibers of the processed material. It is possible to obtain a tape of fibrous material immediately before being fed into the unit, for example, by applying a uniform layer of this material to the conveyor belt 4. After passing through the unit and under the influence of the nozzle device 8 with means 9 for supplying high pressure liquid, the fibers are mixed up in the material belt, and it becomes unified, consisting of interconnected intertwined individual fibers of the primary fibrous material. Mixing liquid can be any known liquid substance, but the most common liquid in nature - water, is preferred for use. After exiting from the nozzle device 8, excess liquid can be removed by suction due to discharge in a vacuum box. The distribution of entangled fibers will be uneven over the thickness of the material layer, the upper outer surface of the material will be denser, and the inner lying on the mesh belt of the conveyor 4 more fluffy. To eliminate this unevenness, the material tape must be processed on the other hand. The material tape can be separated from the mesh belt of the conveyor 4 by any known method or device, the simplest and most common is the device with a string (thin wire), which is tightly stretched across the mesh belt of the conveyor 4 and pulls the material fibers from the mesh belts or breaks them, thereby breaking the mechanical connection of the tape of fibrous material and the mesh belt of the conveyor 4. After that, the tape of fibrous material is fed into the material storage device 2 or 3, for example, wound on a storage drum I either fit in a box drive.

A material tape, for example, wound on a drum, is removed from the quick couplers and turned over together with the drum and again placed on the mesh belt of the conveyor 4 and tucked into the gap under the nozzle device 8 with means 9 for supplying high pressure liquid and the device 10 for attaching the nozzle device 8. Again mounted on the second drum and drive the mesh belt of the conveyor 4 and the drum winding drive, reprocessing the material tape from the other side.

The material separator 13 from the perforated mesh belt 14 and the support roller 15 can be rearranged when the direction of movement of the belt 14 is changed, or two material separators 13 from the perforated tape 14 and the support roller 15 at both ends of the conveyor 4 can be manufactured and installed.

The required number of passes is determined by the desired end result.

The more passes, the denser the final material tape. If necessary, the tape of the material can be processed in certain predetermined places repeatedly and at the same time a pattern will be obtained on the surface of the specified tape, for example in the form of rhombuses. The resulting pattern is determined by the speed of movement of the mesh belt of the conveyor 4 and the movement of the drive of the device 10 for fastening the nozzle device 8. When plane-parallel rotational movement relative to the selected center of rotation of the device 10 for fastening the nozzle device 8, complex curves of epicycloids or trochoids will be obtained. Changing the mounting height of the nozzle device 8 above the material tape will change the width and depth of the part of the material processed by one nozzle. The farther the nozzle is, the wider the processing strip and the less depth and intensity of the impact. The complex spatial movement of the device 10 for mounting the nozzle device 8 will allow you to change the properties of the processed material over a wide range.

The implementation of the storage of material in the form of a box-shaped drive installed with the possibility of rotation and revolution of the material, does not fundamentally change the sequence of work with the tape of fibrous material, but simplifies the manipulation of its position; since the rotation of the box-type drive around the vertical axis does not require unlocking the quick-connects, and the design of the box-shaped drive does not require material winding devices, the material itself fits into the drive.
