Abstract
The invention discloses a vortex type weft catching device. The vortex type weft catching device comprises a cone-shaped cover body and a weft catching component, a first opening is formed in the cone top of the cone-shaped cover body while a second opening is formed in the cone bottom, the first opening is provided with an air exhaust negative pressure component, the second opening faces to the weft yarn flying direction, the weft catching component is arranged at the outer side of the first opening, and a vortex-shaped flow deflector is mounted in the cone-shaped cover body. According to the vortex type weft catching device, air current in the cone-shaped cover body is attracted by the negative pressure component to move, the air current begins to move in a vortex mode under the influence of the flow defector, when the weft yarn passes, the weft yarn does not bear the lateral force of the air current at the vortex air current center, and therefore, the weft yarn flight path is automatically corrected to the vortex air current center, and the weft yarn picking precision is guaranteed.
Description
Affiliated technical field
The present invention relates to textile weaving machine apparatus field, especially, is that the Scroll-tupe on a kind of shuttleless loom is caught Weft handling device.
Background technology
Shuttleless loom is after fly-shuttle loom, a kind of new loom of birth.Shuttleless loom with its weigh light, vibrate little, noise is low, the speed of a motor vehicle is fast, efficiency advantages of higher, has captured rapidly loom market.The common basic characteristics of shuttleless loom are that weft yarn package is separated from shuttle, or only carrying a small amount of weft yarn replaces massive shuttle with small and light weft insertion device, for high speed wefting insertion provides favourable condition.
The filling insertion way of shuttleless loom is with media such as jet, water sprays, weft yarn to be drawn, because the media such as jet, water spray itself do not have the same weight of shuttle of fly-shuttle loom, therefore, the weft yarn of shuttleless loom easily searches out the interference of weight, air-flow, static etc., therefore shuttleless loom is higher to the required precision of catching Weft handling device of seizure weft yarn, if adopt to catch Weft handling device precision not high enough, be easy to occur sluff-offs accident, affect production efficiency.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of Scroll-tupe to catch Weft handling device, this Scroll-tupe is caught Weft handling device can make weft yarn enter while catching Weft handling device, keeps flight precision.
The technical solution adopted for the present invention to solve the technical problems is:
This Scroll-tupe is caught Weft handling device and is comprised taper cover body and catch latitude member, the vertex of a cone of described taper cover body and the cone end, are respectively arranged with the first opening and the second opening, described the first opening is provided with the negative pressure member of bleeding, described the second opening is just to the sudden direction setting of described weft yarn, described in described the first open outer side arranges, catch latitude member, in described taper cover body, be equipped with circinate flow deflector.
As preferably, in described taper cover body, be also equipped with the gas spout that whirlpool shape distributes.
As preferably, described negative pressure member is the puff prot that ring is located at the first open outer side.
The invention has the advantages that:
Air-flow in described taper cover body is by negative pressure member attractive motion, under the impact of described flow deflector, air-flow starts the motion of whirlpool shape, because weft yarn is through out-of-date, only be not subject to the side force of air-flow at vortical flow center, therefore weft yarn flight path is revised automatically to described vortical flow center.
Brief description of the drawings
Fig. 1 is the structural representation that this Scroll-tupe is caught Weft handling device.
Fig. 2 is the distributed architecture schematic diagram that this Scroll-tupe is caught Weft handling device flow deflector.
Fig. 3 is the structural representation that this Scroll-tupe is caught Weft handling device gas spout.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the present embodiment, consult Fig. 1 and Fig. 2, this Scroll-tupe is caught Weft handling device and is comprised taper cover body 100 and catch latitude member 300, the vertex of a cone of described taper cover body 100 and the cone end, are respectively arranged with the first opening 110 and the second opening, described the first opening 110 is provided with the negative pressure member of bleeding, described the second opening is just to the sudden direction setting of described weft yarn, catches latitude member 300 described in described the first opening 110 arranged outside, is equipped with circinate flow deflector 120 in described taper cover body 100.
Consult Fig. 3, in described taper cover body 100, be also equipped with the gas spout 130 that whirlpool shape distributes, the rotation of air-flow of described taper cover body 100 of accelerating to flow through of gas that described gas spout 130 sprays, coordinates with described negative pressure member simultaneously, increases the flow velocity of described taper cover body 100 interior air-flows.
Above-mentioned Scroll-tupe is caught Weft handling device, described negative pressure member is the puff prot 200 that ring is located at the first opening 110 outsides, the described puff prot 200 that ring is established is in the time of ejection high velocity air, the air-flow that is positioned at described puff prot 200 centers is driven, on described the first opening 110, form air-breathing negative pressure, owing to not adopting traditional pipeline air suction mode, ensure unimpeded in weft yarn flight path.
Above-mentioned Scroll-tupe is caught the principle of Weft handling device:
The described puff prot 200 that ring is established is in the time of ejection high velocity air, the air-flow that is positioned at described puff prot 200 centers is driven, on described the first opening 110, form air-breathing negative pressure, air-flow in described taper cover body 100 is by vacuum suction campaign, under the impact of described flow deflector 120, air-flow starts the motion of whirlpool shape, because weft yarn is through out-of-date, only be not subject to the side force of air-flow at vortical flow center, therefore weft yarn flight path is revised automatically to described vortical flow center (being taper cover body 100 center).
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., all should be included in protection scope of the present invention.
