RU39602U1 - DEVICE FOR FORMING FIBROUS FLOORS - Google Patents

Abstract

The utility model relates to textile engineering, in particular to the design of a condenser for textile machines, and can be used both for intermediate layer formation of fibrous webs in the process, and for the production of the final product, for example, non-woven material. To do this, in the device for forming the fibrous flooring, the straight sections of the plates are located stepwise from the ends to the center, with the length of each subsequent straight section starting from the end of the previous one.

Description

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

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 the fibrous flooring on the surface of the condenser over its entire width.

There is also known a device for forming flooring, which has found application in the composition of the combing unit AChM-14U [2]. The disadvantage of this device is its complexity due to the presence of rotating elements inside the condenser, its clogging with fiber and dust when the air stream leaves the condenser body and the difficulty in maintenance.

As a prototype, a device for forming a fibrous flooring [3] is taken, containing a perforated drum with a fixed tube installed in it with a slit and means for distributing the fibrous flooring, made in the form of a rectangular box with symmetrically mounted arcuate plates in it.

The disadvantage of this device is that the plates coming from the ends of the box create increased resistance to the movement of the air stream when dividing it into components of the stream.

The technical result of the claimed utility model is to reduce the resistance to movement of the air stream and increase the efficiency of formation of the fibrous flooring on the surface of the condenser.

The specified technical result is achieved in that in a device for forming a fibrous flooring containing a perforated drum with a perforated pipe installed inside it with a slit and means for distributing the air flow, made in the form of a rectangular box fixed inside it with symmetrically mounted arcuate plates in it ending in rectilinear

sections, according to the utility model, the straight sections of the plates are located stepwise from the ends to the center, while the length of each subsequent straight section begins from the end of the previous one.

The offset of the separation pneumatic channels inside the duct relative to each other provides a sequential separation from the main stream of the component air jets and a decrease in the area of interaction of the air flow with the pneumatic channels.

The drawing shows a process diagram of a device for forming a fibrous flooring.

The device comprises a mesh drum 1, in which a fixed tube 2 with a slit 3 is installed. A duct 4 is mounted in the tube 2 with symmetrically and stepwise arranged arcuate plates 5. Transitional diffusers are installed at the ends of the box 6. The plates consist of rectilinear and arcuate sections and are installed in each parts of the box with an offset to each other from the ends to the center so that the length of each subsequent straight section starts from the end of the previous one.

The device operates as follows. The air-fibrous flow from the working body of the machine through the pneumatic channel (not shown) is directed to the mesh drum 1, where the fibrous component of the flow settles on the surface of the drum and when it is rotated is removed from the machine, and air passes through the mesh of the drum 1, slot 3 of the fixed pipe 2 and, falling into the box 4, it is evenly distributed along the pneumatic channels formed by the plates 5, through diffusers 6 it is discharged to the suction line. In this case, the sequential integration of the suction air jets into a single main flow is ensured as they exit the corresponding pneumatic channels with minimal loss of resistance to movement from the side of the air flow distribution means.
