Detailed description of the invention
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of Venturi tube false twisting buncher, comprise: a preferably Venturi tube 2 and 10 or 2 arms 10 of 6 arms of being tightly connected with Venturi tube 2, the compression section 4 that Venturi tube 2 two ends are horn opening and expansion segment 8, centre is the trunnion section 6 that cross section radius is less, arm 10 is tilted to compression section 4 and is communicated with 6 sealings of trunnion section, arm 10 axis and trunnion section 6 axis angles are acute angle, preferably acute angle angle is 15 °-90 °, and the air-flow in arm 10 can be easy to be driven towards expansion segment 8 and flow by Venturi tube 2 like this.Be communicated with external device sealing for the ease of the free end of Venturi tube 2 and the free end of arm 10, each free end is designed to the clamping ring 12 turning up, and compound rubber circle is as sealing auxiliary component.In order to reduce the impact of arm 10 air inlets on trunnion section 6 internal gas pressures, arm 10 internal diameters are less than trunnion section 6 internal diameters.Compression section 4, trunnion section 6 and expansion segment 8 are designed to coaxial configuration and are convenient to gas and yarn 14 fast smoothly by Venturi tube 2.In several embodiment of the present invention, the number of arm 10 is respectively 2 or 3 or 4 or 6, for the active force that in balance every arm 10, gas is aspirated by Venturi tube 2, the gas flow rate that reaches every arm 10 is consistent, all arms 10 are arranged into centrosymmetric structure taking the center of circle of trunnion section cross section as the center of circle, the internal diameter size of every arm 10 simultaneously, and every arm 10 axis are all identical with Venturi tube 2 axis angles.As shown in Fig. 2 or 3 along in the perspective view of Venturi tube 2 axis directions, each arm axis 16 is tangent with the circle of compression section 4 peripheries, there is anticlockwise rotation in the interior meeting of trunnion section 6 in the yarn 14 being drawn by high velocity air like this from every arm 10, when threads 14 converges, mutually rotating and be intertwined, in this process, the boundling of yarn 14 and false twisting are carried out simultaneously, filament fiber in yarn 14 is broken up network by high velocity air and is added the false twisting effect being temporarily added on yarn 14 together, and yarn 14 can be by boundling closely together.
The present invention in use, as shown in Figure 4, compressed air enters Venturi tube 2 with certain speed from compression section 4, because the compression section 4 cross section radiuses of air stream warp dwindle gradually, compressed-air actuated flow velocity increases thereupon, air velocity maximum while arriving trunnion section 6, from Bernoulli equation, air velocity is inversely proportional to air pressure herein, it is the air pressure minimum of trunnion section 6, air pressure in arm 10 is greater than the air pressure in trunnion section 6, air in arm 10 is also inhaled into trunnion section 6 in arm 10, now the air-flow in every arm 10 be pooled to trunnion section 6 with the air-flow in Venturi tube 2 in together with move to expansion segment 8, the direction top rail section radius that air-flow is flowed through at expansion segment 8 becomes large gradually, gas flow rate diminish gradually slow down and, last air-flow flows out Venturi tube 2.Yarn 14 enters arm 10 separately from the free end of every arm 10, and all yarns 14 converge in trunnion section 6, enters expansion segment 8 finally leave Venturi tube 2 in company with air-flow.The tractive force maximum of the air-flow that yarn 14 is subject in trunnion section 6, multi-strand yarns 14 converges the rear mutual entanglement that is rotated counterclockwise, and high velocity air is broken up mutual network together by filament fiber, above false twisting and network boundling interact, and make threads 14 have each other obvolvent effect comparatively closely.
Be enlightenment according to desirable embodiment of the present invention above, by above-mentioned description, related personnel can, not departing from the scope of this invention technological thought, carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to claim scope.
