Description
Technical field
The utility model belongs to field of textile machinery, especially relates to a kind of air-jet loom.
Background technology
In recent years, air-jet loom becomes the shuttleless loom machine that technological progress is the fastest, development is the most active, and development speed occupy first of the shuttleless looms such as water spray, arrow shaft, projectile shuttle.The feature of air-jet loom utilizes flexible year latitude body---the high velocity air that compressed air produces produces frictional force to weft yarn surface, fell is passed through in weft yarn traction and completes wefting insertion process.Its speed is fast, efficiency is high, product quality and the high advantage of automaticity level become and weave the type that industry has development potentiality most future.The main wefting insertion parts of air-jet loom are main burners, and the design object of main burner obtains velocity of sound or transonic air outlet velocity to ensure the normal wefting insertion of air-jet loom.Under the current filling insertion way being main flow with main burner+auxiliary nozzle+special-shaped reed, main burner and auxiliary nozzle are had one's own work to do, often take the design of " high pressure, low discharge ", namely less the and scheme that length is longer in very little and yarn-guide tube aperture is amassed in throat section.Corresponding also has the setting of main burner Weft insertion method.In theory, the varietal adaptation of modern air-jet weaving equipment is comparatively strong, light, in, heavy, low, high unique fabric all can produce, the fabric originally produced on gripper shuttle loom and Rapier looms, also can produce now on air-jet loom.But find from the process of production practices, current air-jet loom is main still for weaving frivolous series products, all kinds of float problem is easily there is in the thick thick grade of weaving fiber compared with when fabric and long filament class elastic type fabric, especially when carrying out wide cut and ultra-wide is weaved, this fibrid easily causes fault in the reduction of long distance wefting insertion occiput kinetic energy, cannot ensure product quality.
Summary of the invention
The utility model is for deficiency of the prior art, provide a kind of air-jet loom in wide size, extra source of the gas can be provided, improve parallel head kinetic energy, increase the length that parallel is advanced, reducing the float problem often occurred when weaving wide cut and ultra-wide is knitted, being also applicable to weave the fabric that parallel is heavier fiber, solving the problem that it comparatively fast loses because of parallel heavier parallel head kinetic energy.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of air-jet loom in wide size, comprise frame, main gas ejecting system, auxiliary gas ejecting system and special-shaped reed, also comprise the bobbin feeler that several match with described special-shaped reed, also comprise gas operated device, described gas operated device comprises the fixed mount matched with described frame, described fixed mount is provided with travelling carriage and high-speed cylinder, travelling carriage described in described high-speed cylinder connects, described fixed mount is provided with several direction recess, described travelling carriage is provided with the roller that several match with described direction recess, described travelling carriage is provided with air track, described air track is provided with sliding part, described sliding part is provided with the air-guide rod matched with described special-shaped reed, described air-guide rod is provided with air guide channel, described air track two ends are provided with electromagnet, described sliding part two ends are provided with the iron block matched with described electromagnet, described air track connects the source of the gas of described main gas ejecting system or described auxiliary gas ejecting system, described air-guide rod is connected with getter device, described air track is also provided with several photoelectricity doors, described sliding part is also provided with the shadow shield matched with described photoelectricity door, described fixed mount is also provided with several positive stop strips, described positive stop strip is positioned at above described travelling carriage, described positive stop strip is provided with the ball matched with described travelling carriage.
In technique scheme, preferably, described air guide channel is provided with dismountable guide head, described guide head is taper, and described guide head bottom is provided with annular aeroscopic plate.
In technique scheme, preferably, between described fixed mount and described frame, be provided with fixed rotating shaft, described fixed mount be also provided with the support bar matched with described frame.
In technique scheme, preferably, described gas operated device comprise can dismantle and match with described fixed mount and guard box.
In technique scheme, preferably, described fixed mount is also provided with dismountable support column.
In technique scheme, preferably, described electromagnet is provided with cushion.
The wefting insertion of existing air-jet loom, mainly compressed air sprays from main burner, and weft yarn sprays main burner under the effect of air-flow, flies in the reed groove of special-shaped reed; The reduction of the weft tracting flow speed caused to prevent Diffusion of gas stream, by pilot jet to reed groove supplemental air flow.But for pilot jet, the air pressure superposition of nozzle is not fine, namely the air-flow that ejects of nozzle before the next nozzle of arrival just similar diffusion be over, so in the flight course of parallel, because Diffusion of gas stream is rapid, the kinetic energy of parallel also lowers rapidly parallel speed is slowed down rapidly.For the fabric of general width, because parallel initial kinetic energy is comparatively large, short-range flight also can keep certain speed, can complete spinstry preferably.But for broad fabrics, present jet mode always cannot allow after parallel long-distance flight and also ensure certain flying speed, is easy to cause weaving fault; For the parallel of heavier-weight, the speed of kinetic energy rejection is faster than the parallel compared with light weight, and the wide cut of weaving is limited, and the weaving effect of air-jet loom to this kind fabric of existing structure is unsatisfactory.The utility model is the improvement to existing air-jet loom, the rear end of special-shaped reed is provided with air-guide rod, air-guide rod can be deep in special-shaped reed, air-guide rod can carry out faster reciprocal motion under the effect of air track, air-guide rod can be coordinated flown the parallel of certain distance, reduce at parallel kinetic energy, after speed loss too much, reduce the diffusion of air-flow by air guide effect allows parallel front form negative pressure simultaneously, keeps the kinetic energy of parallel in special-shaped reed rear end and speed.Because parallel flying speed is very fast, in order to the speed allowing the reciprocating motion of air-guide rod can catch up with parallel, specially adopt two-stage reciprocating motion, travelling carriage also can be moved relative to fixed mount, improve the reaction susceptibility of air-guide rod, make the speed of air-guide rod can catch up with the flying speed being in special-shaped reed end parallel completely.The air guide effect of air-guide rod is mainly to the absorption of parallel front end air, the dynamics drawn can reduce gradually along with when air-guide rod exits special-shaped reed, after parallel flies completely, air-guide rod also can be withdrawn into special-shaped reed completely, does not affect the operation that loom is later.When carrying out the flight of next root parallel, air-guide rod again stretches in special-shaped reed and carries out air guide work.By this set, air-jet loom can be allowed to obtain when weaving wide cut textiles and the heavier textiles of fiber effect of better weaving.
Compared with prior art, the beneficial effects of the utility model are: can provide extra source of the gas, improve parallel head kinetic energy, increase the length that parallel is advanced, reduce the float problem often occurred when weaving wide cut and ultra-wide is knitted, also be applicable to weave the fabric that parallel is heavier fiber, solve the problem that it comparatively fast loses because of parallel heavier parallel head kinetic energy.
