Abstract

The utility model discloses a tight spinning pneumatic condensation device comprising a negative-pressure pipe [3] and a grid ring [4] sheathed on the negative-pressure pipe. The negative-pressure pipe is provided with a plurality of air-current guide holes and a guide slot of the grid ring. A tensioning mechanism of the grid ring is composed of a tension holdfast [5] and a spring [6] which is fixed between the negative-pressure pipe [3] and the tension holdfast [5] via a spring plunger [7]. In the utility model, owing to that the spring is installed between the tension holdfast and the negative-pressure pipe, the tension of the grid ring can be automatically adjusted via the spring, the requirement of elasticity of material of the grid ring can be reduced, and the service life can be prolonged. The utility model has the advantages of simple structure, and convenient processing and installation.

Description

A kind ofly closely spin pneumatic coacervation device

Affiliated technical field

The utility model relates to the pneumatic coacervation device of the yarn that is applied on the compact spinning machine.

Background technology

The compact spinning technology is the new spinning technique of foreign study recent years, is characterized in reducing the yam surface filoplume significantly, and yam surface is clear bright and clean, and yarn strength improves.One of its key technology is that (spinning triangular zone) increased the pneumatic coacervation device of filoplume behind traditional spinning machine front roller nip line, this pneumatic coacervation device is made up of negative pressure pipe and the grid ring that is enclosed within the densely covered pore in surface on the negative pressure pipe, have some air-flow gathering sills on the negative pressure pipe one side pipe wall, each air-flow gathering sill is corresponding to an one thread, the tube wall upper edge at each air-flow gathering sill place is circumferentially with the grid ring gathering sill, grid ring is enclosed within the gathering sill, and negative pressure Guan Yiduan communicates with negative pressure source.Grid ring is rotated around the negative pressure tube-surface by resistance twist roller driving ring, yarn is close on the grid ring under the effect of negative pressure pipe roller, because the suction function of negative pressure pipe, the filoplume on the yarn are attached to the grid ring surface and rotate with grid ring, warp yarn is wrapped on the yarn from sth. made by twisting.Because grid ring directly is enclosed within on the negative pressure pipe, the tensile force of grid ring can not be regulated, can only rely on the elasticity of self material, tension is unfavorable for rotating, cross Song Zehui and move axially and depart from the yarn walking position, thereby its elasticity is difficult to grasp, cause and use inconvenience, and the flexibility decrease of grid ring promptly need change, and service life is low.

Summary of the invention

To be solved in the utility model is that above-mentioned grid ring tensile force can not be regulated, the problem that cause its elasticity to be difficult to grasp, service life is low.

The utility model is a kind of closely to spin pneumatic coacervation device, comprise the negative pressure pipe and be enclosed within the gather grid ring of pore of surface on the negative pressure pipe, have some air-flow pilot holes on the negative pressure pipe one side pipe wall, the tube wall upper edge at air-flow pilot hole place is circumferentially with the grid ring gathering sill, grid ring is enclosed within the gathering sill, negative pressure Guan Yiduan communicates with negative pressure source, it is characterized in that it also comprises a grid ring strainer, described strainer is made up of tension support and spring, tension support is elongated, be fixed on the negative pressure pipe opposite side tube wall relative with having air-flow pilot hole tube wall by grid ring, spring is contained between negative pressure pipe and the tension support.

The utility model is owing to be equipped with spring between tension support and the negative pressure pipe, and the tensile force of grid ring can obtain the automatic adjusting of spring, can reduce the requirement to grid ring self elastic properties of materials, and can prolong its service life; And structure is also very simple, is convenient to processing and installation.
