Abstract

The utility model provides a kinetic energy compensation structure of a water-jet loom. The kinetic energy compensation structure of the water-jet loom comprises a spray nozzle arranged at the weft insertion end of the loom and comprises a spray nozzle core and a yarn guiding tube surrounding the mouth portion of the spray nozzle core, a weft yarn passes through the spray nozzle core, high-pressure water flows pass through a high-pressure space formed by the outer side of the spray nozzle core and the inner side of the yarn guiding tube, the high-pressure space is communicated with a water inlet channel for supplying high-pressure water flows, and a second spray opening with the axis parallel to the axis of the yarn guiding tube is evenly distributed at the mouth portion of the yarn guiding tube and communicated with the water inlet channel. The high-pressure water flows sprayed by the second spray opening compensate insufficient weft yarn kinetic energy and rectify deviating weft yarn tracks.

Description

Water jet looms kinetic energy collocation structure

Affiliated technical field

The utility model relates to field of textile machinery, especially, is a kind of kinetic energy collocation structure for water jet looms shower nozzle.

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 filling insertion way of shuttleless loom is diversified, has the modes such as arrow shaft, injection (jet, water spray), projectile shuttle, multiple-shed (heterogeneous) and braiding.

Water jet looms belongs to jet loom, is to utilize water as wefting insertion medium, by jet water course, weft yarn is produced to frictional traction, makes the weft yarn on fixed bobbin introduce shed open.The current convergence of water jet looms is good, and water is also large to the frictional traction of weft yarn in addition, therefore makes the weft yarn flying speed of water jet looms, loom speed all occupy first of all kinds of looms.Because the concentration of current is better, on water jet looms without any anti-current disperser, even if its reed width also can reach more than two meters like this.But use water jet looms will to expend a large amount of water as the mode of wefting insertion, in-flight at weft yarn, weft yarn can't be faster by straight ahead and kinetic energy decay simultaneously.

Utility model content

In order to address the above problem, the purpose of this utility model is to provide a kind of water jet looms kinetic energy collocation structure, and this water jet looms kinetic energy collocation structure can supplement kinetic energy in-flight at weft yarn.

The utility model solves the technical scheme that its technical problem adopts:

This water jet looms kinetic energy collocation structure comprises the nozzle that is arranged on loom picking end, described nozzle comprises nozzle core and is centered around the yarn-guide tube in described nozzle core oral area outside, described nozzle core passes through weft yarn, in the high-pressure space that described nozzle core outside and described yarn-guide tube inner side form, there is High-Pressure Water to pass through, described high-pressure space is communicated with the intake tunnel of the described High-Pressure Water of a supply, the oral area of described yarn-guide tube is evenly equipped with the second spout that axis is parallel to described yarn-guide tube axis, and described the second spout is communicated with described intake tunnel.

As preferably, the quantity of described the second spout is even number.

As preferably, in described the second spout, be provided with electromagnetic valve, described the second spout of switching that described electromagnetic valve is interrupted in the time of picking.

As preferably, when each picking, the High-Pressure Water of described the second spout ejection is later than the High-Pressure Water of described yarn-guide tube ejection.

The utility model has the advantage of:

Utilize the High-Pressure Water of described the second spout injection around the weft yarn of motion, described High-Pressure Water is owing to moving in the same way with weft yarn, and therefore, the air between High-Pressure Water and weft yarn is owing to being crowded together, the flow velocity of air is larger than outside, and pressure will be smaller than outside.Like this, the pressure differential of air will make the combination at the volley of High-Pressure Water and weft yarn, and at picking end, High-Pressure Water will supplement the deficiency of weft yarn kinetic energy and the skew of correction weft yarn track.

Fig. 2 is the A-A sectional structure schematic diagram of this water jet looms kinetic energy collocation structure Fig. 1.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is further illustrated:

In the present embodiment, consult Fig. 1 and Fig. 2, this water jet looms kinetic energy collocation structure comprises the nozzle that is arranged on loom picking end, described nozzle comprises nozzle core 300 and is centered around the yarn-guide tube 100 in described nozzle core 300 oral area outsides, described nozzle core 300 is by weft yarn 10, in the high-pressure space that described nozzle core 300 outsides and described yarn-guide tube 100 inner sides form, there is High-Pressure Water to pass through, described high-pressure space is communicated with the intake tunnel 120 of the described High-Pressure Water of a supply, the oral area of described yarn-guide tube 100 is evenly equipped with the second spout 200 that axis is parallel to described yarn-guide tube 100 axis, described the second spout 200 is communicated with described intake tunnel 120.

Above-mentioned water jet looms kinetic energy collocation structure, the quantity of described the second spout 200 is even number, described in even number, the second spout 200 can make being distributed in around weft yarn 10 axis of High-Pressure Water symmetry that the second spout 200 sprays, can offset the attraction of weft yarn 10 to two of symmetry strands of High-Pressure Waters, prevent weft yarn 10 offset movement tracks.

Above-mentioned water jet looms kinetic energy collocation structure, is provided with electromagnetic valve 210 in described the second spout 200, described the second spout 200 of switching that described electromagnetic valve 210 is interrupted in the time of picking, and the High-Pressure Water of interruption can reduce the use amount of water.

Above-mentioned water jet looms kinetic energy collocation structure, when each picking, the High-Pressure Water that described the second spout 200 sprays is later than the High-Pressure Water that described yarn-guide tube 100 sprays, because the cross section of weft yarn 10 is larger, therefore the suffered air drag of High-Pressure Water that the air drag being subject to sprays with respect to described the second spout 200 is larger, therefore the weak higher pressure current of weft yarn 10 speed are faster, therefore High-Pressure Water is later than weft yarn 10 and sprays, the head of High-Pressure Water could be in the end of picking and weft yarn 10 combinations, otherwise the head of High-Pressure Water is by the head faster than weft yarn 10.

The principle of above-mentioned water jet looms kinetic energy collocation structure:

When picking, the second spout ejection High-Pressure Water, nozzle core 300 sprays the bond of weft yarn 10 and High-Pressure Water, and the air between High-Pressure Water and weft yarn 10 is owing to being crowded together, and the flow velocity of air is larger than outside, and pressure will be smaller than outside.Like this, the pressure differential of air will make High-Pressure Water and weft yarn 10 combination at the volley, and at picking end, High-Pressure Water will supplement the deficiency of weft yarn 10 kinetic energy and the skew of correction weft yarn 10 tracks.

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 amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
