Abstract

A device for forming a fibrous flooring comprising a perforated drum with a fixed tube with a slit installed in it, a sealing roller, a pneumatic channel and means for distributing air flow, characterized in that the latter is made in the form of a rectangular box fixed inside a fixed pipe with symmetrically mounted arcuate vertical plates bent from the slit of the fixed pipe to the ends on which the transition diffusers are mounted.

Description

DEVICE FOR FORMATION

The utility model relates to textile engineering, in particular to the design of a condenser for textile machines, and can be used both for the intermediate layer formation of fibrous scrubs in a technological process and for the production of a final product, for example, non-woven materials.

A device for the formation of the canvas, containing a condenser adjacent to it the shaft of the duct, a sealing roller installed at the outlet of the formation zone 1.

The disadvantage of this device is the lack of uniformity of air flow on the surface of the condenser over its entire width.

As a prototype of a device for forming a fibrous flooring, a device for removing the webs on a carding machine is adopted, containing a removable roller, a chamber with an adjacent condenser equipped with means for regulating the air supply, which is made in the form of a disk condenser installed inside the mesh drum with cone-shaped mounted on it nozzles 2.

The use of this device does not sufficiently exhaust air suction along the width of the condenser, as a result of which the formed fibrous flooring is uneven in linear density along its width. IPC: D01S25 / 00 D01S15 / 46 of fibrous flooring

The technical result of the claimed utility model is to improve the quality of the resulting flooring by aligning the air flow across the width of the device.

The specified technical result is achieved in that in a device for forming a fibrous flooring containing a perforated drum with a fixed tube with a slit installed therein, a sealing roller, a pneumatic channel and means for distributing air flow, the latter is made in the form of a rectangular box fixed inside the fixed pipe with a symmetrically mounted in it arcuate vertical plates bent from the slit of the fixed pipe to the ends, and transitional diffusers are installed on the ends of the box.

The use of a rectangular box with arcuate vertical plates makes it possible to divide the main air flows passing through the ends of the mesh drum into a series of vertical component flows and by arranging a uniform air suction along the width of the drum to obtain a uniform fiber thickness on its surface.

In FIG. 1 presents a process diagram of the inventive device;

In FIG. 2 is a section AA in FIG. 1;

In FIG. 3 - non-passing diffuser.

A device for forming a fibrous flooring comprises a condenser 1, consisting of a perforated drum covered with a fine-mesh metal mesh, inside which a rectangular box 4 is mounted in a fixed tube 2 with a slit 3, in which arcuate vertical plates 5 are symmetrically fixed so that one end is located in the outlet end of the box, and the other on its open side, located against the slot 3 in the fixed pipe 2. From the ends of the box mounted transitional diffusers 6, mating directly the coal section of the duct 4 with the cross-section of the stationary pipe 2. Between the working body 7 and the condenser 1 on the side of the slot 3 there is a pneumatic chamber 8 for transporting the air-fibrous flow, and a sealing roller 9 is installed in the zone of formation of the fibrous flooring.

A device for forming fibrous naprush works as follows.

The fibrous product from the working body 7 due to the centrifugal force and the air draft created by the fan (not shown in the drawing) is sent to the pneumatic chamber 8, which, having nosed, settles on the mesh surface of the condenser 1, forming a fibrous layer on it by the addition of shreds, groups and individual fibers , which is sealed with a roller 9 and then removed from the surface of the drum.

With the help of arcuate plates 5, the end main suction air streams are divided vertically into component streams, which, being oriented to the corresponding sections of the slit 3 of the fixed pipe 2, ensure uniform suction of air from the associated zones of the mesh drum along its width. The selection of the optimal parameters thus formed of the internal non-pneumatic channels (the number of plates and the distances between them), taking into account the resistance to air flow due to the difference in the length of the internal non-pneumatic channels, will enhance the effect of uniform suction of air from all sections of the perforated condenser drum 1 along its width.

Air, sucking through the mesh surface of the drum 1, passes through the slot 3 of the fixed pipe 2, the internal non-pneumatic channels formed by the arcuate plates 5 and through the diffusers 6, connecting the duct 4 with the ends of the fixed pipe 2, are discharged through the air ducts to the fan or filters.

A device for forming a fibrous flooring receives rotation from a machine drive.

The proposed design allows to obtain a fibrous flooring of improved quality by leveling the conditions for its formation across the width of the device.
