Abstract
The utility model provides an eddy type weft catching device. The eddy type weft catching device comprises a conical cover and a weft catching component. The cone top and the cone bottom of the conical cover are provided with a first opening and a second opening respectively. The first opening is provided with a pumping negative pressure component, the second opening is formed right opposite to the weft flying-over direction, the outer side of the first opening is provided with a weft catching component, and the conical cover is internally provided with an eddy-shaped diversion sheet. According to the eddy type weft catching device, the airflow in the conical cover is attracted by the negative pressure component to move, the airflow starts to do eddy movement through the diversion sheet, and due to the fact that when the weft passes by, the weft is not subjected to the lateral force of the airflow only at the center of the airflow in the eddy, the weft flying track is automatically corrected to the center of the airflow of the eddy, and the weft throwing precision is guaranteed.
Description
Affiliated technical field
The utility model 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.
Utility model content
In order to address the above problem, the purpose of this utility model is to provide a kind of Scroll-tupe to catch Weft handling device, and this Scroll-tupe is caught Weft handling device can make weft yarn enter while catching Weft handling device, keeps flight precision.
The utility model solves the technical scheme that its technical problem adopts:
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 over against 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 located at the puff prot of the first open outer side for ring.
The utility model has the advantage of:
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 at vortical flow center, be not subject to the side force of air-flow, so weft yarn flight path is revised automatically to described vortical flow center.
Accompanying drawing explanation
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.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
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 over against 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 the gas of described gas spout 130 ejections, 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 for encircling the puff prot 200 that is located at the first opening 110 outsides, the described puff prot 200 that ring is established is when 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 when 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 at vortical flow center, be not subject to the side force of air-flow, so 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 utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included in protection domain of the present utility model.
