Abstract
The utility model discloses a high speed air flow drawing machine, comprising a nozzle, an air sleeve, a drawing pipe, a housing, a hole seat and a group of air deflectors, wherein, the nozzle is positioned at the housing top, while the drawing is arranged under the nozzle, the air deflector positions between the housing and the drawing pipe, besides, the hole seat is arranged at the housing bottom, and the nozzle is provided with a fiber bundle inlet, and the housing side surface is provided with a compressed air inlet; moreover, the air sleeve wall is provided with a group of small holes, while a through hole is arranged on the air deflector. Being able to achieve the extension of the fiber at a high speed, the utility model has advantages of easy adjusting the air flow speed, greatly increasing the air flow speed and enhancing the fiber rigidity and so on.
Description
One, technical field:
The utility model relates to a kind of air drawing device, and is especially relevant with the high velocity air extension apparatus.
Two, background technology
Needing in the spun-bond process non-weaving cloth production process that fiber is carried out drawing-off handles, to improve the intensity of fiber, existing slit air drawing device is big because of its passage section, reduced air velocity, thereby the draft speed deficiency of fiber, cause fibre strength and the nonwoven product intensity made by it lower.
Three, summary of the invention
The purpose of this utility model provides a kind of air velocity height, can make fiber do the high speed drawing-off, improves the high velocity air extension apparatus of fibre strength.
For achieving the above object, the utility model is realized by following technical solution: the high velocity air extension apparatus comprises nozzle, the water conservancy diversion cover, drafting tube, shell, hole seat and one group of deflector, nozzle is located at shell upper, and drafting tube is located at the nozzle below, deflector is between shell and drafting tube, the hole seat is located at outer casing underpart, is provided with the fibre bundle inlet on nozzle, is provided with the compressed air inlet at the shell side face, on the water conservancy diversion jacket wall, establish one group of aperture, on deflector, be provided with through hole.
Described high velocity air extension apparatus, its deflector is provided with three, they are three grades of deflectors, secondary deflector and one-level deflector, lay respectively in the shell go up, in, following three positions, uniform 16 through holes on three grades of deflectors, uniform 8 through holes on the secondary deflector, uniform 4 through holes on the one-level deflector.
Described high velocity air extension apparatus, its hole seat are a band internal thread hole seat, are provided with the O RunddichtringO between hole seat and the drafting tube, and shell is a cylindrical case.
The utility model compared with prior art has the following advantages: (one) adopts the tubular type shape, can be by adjusting the spout gap, the convenient air velocity of adjusting; (2) be to have improved air velocity greatly, can do the high speed drawing-off, improved the intensity of fiber fiber.
Four, description of drawings
Fig. 1 is the structural representation of the utility model high velocity air extension apparatus.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the high velocity air extension apparatus, comprise nozzle 1, water conservancy diversion cover 2, drafting tube 4, shell 6, hole seat 9 and one group of deflector, nozzle 1 is located at shell 6 tops, and drafting tube 4 is located at nozzle 1 below, deflector is between shell 6 and drafting tube 4, hole seat 9 is located at shell 6 bottoms, is provided with fibre bundle inlet 10 on nozzle 1, is provided with compressed air inlet 11 in shell 6 sides, overlap at water conservancy diversion and to establish one group of aperture 12 on 2 walls, be provided with through hole 13 on deflector, this group deflector is provided with three, and they are three grades of deflectors 3, secondary deflector 5 and one-level deflector 7, on laying respectively in the shell 6, in, following three positions, uniform 16 through holes 13 on three grades of deflectors 3, uniform 8 through holes 13 on secondary deflector 5, uniform 4 through holes 13 on one-level deflector 7, hole seat 9 are a band internal thread hole seat, in order to regulate spout gap 14, be provided with O RunddichtringO 8 between hole seat 9 and the drafting tube 4, shell 6 is a cylindrical case.
This high velocity air extension apparatus bosom part is the passage of fiber, the compressed air that enters shell 6 by one group of deflector after, uniformity around guaranteeing, when spout is made high velocity jet, make the fiber entry place of central fiber passage produce negative pressure, this negative pressure is in the fiber suction passage, along with the high speed of air-flow is sprayed downwards, the pulling fiber moves downward, obtain up to 5000m/minute more than draft speed, this draft speed makes fiber reach full state of orientation, the quality that possesses high-strength flatness makes the non-weaving cloth of making have the quality of high-strength flatness, in addition, when if the single fiber radical of fibre bundle changes, can regulate the spout gap and adapt with it.
