Abstract
The utility model provides a tractive and yarn-arranging nozzle for free ends of weft yarns for an air-jet loom. The tractive and yarn-arranging nozzle comprises a nozzle body, a nozzle core, the nozzle and pipe joints. An annular gap is formed between the nozzle core and the nozzle. The nozzle body is symmetrically provided with two air inlets, each of which is connected with a pipe joint. The tractive and yarn-arranging nozzle for the free ends of the weft yarns for the air-jet loom has following beneficial effects: machining manufacturability of parts is improved; machining procedures are reduced; machining duration is saved; the yield rate of the parts is increased; and integrated manufacturing cost is substantially lowered.
Description
Technical field
The utility model relates to a kind of mechanical device part of air-jet loom, especially relates to a kind of weft in jet looms free end tractive row yarn nozzle.
Background technology
Mostly the tractive row yarn nozzle of weft in jet looms free end tractive row yarn feeding device is to continue to use main burner structure at present, and as shown in Figure 1, described nozzle 3 comprises nozzle body 1 and is positioned at the nozzle core 2 of nozzle body 1.When compressed air by nozzle body 1 on a unique air admission hole while entering the cavity that nozzle body 1 and nozzle core 2 form, some air-flow is circulation state, the rear annular slot of axial flow state flow to nozzle core and nozzle formation that all become of rectifier tank 5 of flowing through on nozzle core 2, described rectifier tank 5 structures are shown in accompanying drawing 2, ejection at a high speed after annular slot obtains accelerating, the air-flow of high velocity jet makes the inner chamber of nozzle core form negative pressure, produces certain negative-pressure air-flow, as shown in Figure 3.Because need to process several rectifier tanks on the very little nozzle core of volume, rectifier tank distribution consistency degree, dimensional accuracy and surface smoothness require all very high, need just can complete special cutter, mould and longer process time, and difficulty of processing is large, yield rate is low, and manufacturing cost is high.
Utility model content
The utility model provides a kind of weft in jet looms free end tractive row yarn nozzle, to ensure under the prerequisite of serviceability, reach raising parts machining process, shorten process time by changing nozzle interior structure, improve yield rate, finally reach the object that reduces manufacturing cost.Its technical scheme is as described below:
A kind of weft in jet looms free end tractive row yarn nozzle, comprise nozzle body, nozzle core, nozzle, between nozzle core and nozzle, be formed with annular slot, also comprise pipe joint, described nozzle body is symmetrically arranged with two air admission holes, and each air admission hole is connected with a pipe joint.
Described nozzle body is provided with two identical, symmetrically arranged air admission holes in aperture.
Described pipe joint is connected with joint by tracheae.
Further, described pipe joint is connected with three-way connection by tracheae.
Length, the aperture of described tracheae are all identical.
The weft in jet looms free end tractive row yarn nozzle that the utility model provides, can improve parts machining process, reduces manufacturing procedure, saves process time, improves parts yield rate, and comprehensive manufacturing cost is significantly reduced.

Detailed description of the invention
The weft in jet looms free end tractive row yarn nozzle that the utility model provides as shown in Figure 4, comprise nozzle body 1, nozzle core 2, nozzle 3, pipe joint 4, described nozzle body 1 has 7, two pipe joints 4 of two identical, symmetrically arranged air admission holes in aperture to be connected with two air admission holes of nozzle body 1 respectively.
Operation principle of the present utility model is as described below, when compressed air 8 by a three-way connection 9 and two with length the tracheae with aperture, in the time that entering into the cavity that nozzle body 1 and nozzle core 2 form, two air admission holes 7 of nozzle body 1 form convection current through pipe joint 4, as shown in Figure 5, due to the pressure of two strands of air-flows, flow velocity, flow, reach the time identical, two strands of circulation compositions in air-flow are cancelled out each other completely, as shown in Figure 6, in being full of whole cavity, air-flow will accumulate the annular slot 10 high speeds ejections that one stable axial flow forms from nozzle core 2 and nozzle 3, the air-flow of high velocity jet makes the inner chamber of nozzle core 2 produce negative pressure, form certain negative-pressure air-flow 6.With negative-pressure air-flow 6, weft yarn free end is drawn onto to tractive in nozzle core and lives, after weft yarn is cut off, be discharged in collection yarn case by air-flow.
The weft in jet looms free end tractive row yarn nozzle that the utility model provides, can improve parts machining process, reduces manufacturing procedure, saves process time, improves parts yield rate, and comprehensive manufacturing cost is significantly reduced.
