Description
Technical field
The utility model relates to a kind of being arranged on and is used for the selvedge device that selvedge is shaped on the shuttleless loom, relates in particular to a kind of being arranged on and is used for the selvedge device that selvedge is shaped on the jet cord fabric loom.
Background technology
Existing air-jet loom, owing to be subjected to the restriction of loom mechanical structure and weaving process thereof, the fabric that weaves generally all is burr, promptly all has parallel the end of a thread to expose on the both sides of the cloth width of cloth, thereby makes many air-jet looms can't directly weave the fabric of band plain edge.In order to solve the deficiency of above-mentioned air-jet loom, the main method that adopts is that mechanical selvedge apparatus is set on air-jet loom at present, this selvedge apparatus is made up of complex mechanical construction comparatively, symmetry is installed in the both sides of the loom cloth width of cloth, when the air-jet loom weaving cord fabric, this device can make the selvedge of cord fabric form plain edge, thereby satisfies the quality requirement of cord fabric.But because the structure of this mechanical selvedge apparatus is comparatively complicated, the required precision height of machine-building, so its manufacturing ten minutes trouble, and price is also very expensive.In a single day during use, if mechanical breakdown takes place, also easily cause the damage of a plurality of parts, maintenance cost is big.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and manufacturing cost is lower, the air-jet loom selvedge device of convenient operating maintenance.
For realizing the purpose of this utility model, a kind of air-jet loom selvedge device, comprise a fixed block, the front side of fixed block offers the V-arrangement opening, the root of V-arrangement opening offers rectangular notch, be provided with the support fixing hole above the fixed block, offer weft yarn between the end face of described fixed block and the rectangular notch and grip air admission hole, corresponding with it, offer weft yarn between the back downside of rectangular notch and fixed block and grip the hole, offer weft yarn in the fixed block inside of weft yarn gripping air admission hole rear side and spray into air admission hole, weft yarn spray into air admission hole respectively with main injection jet and some guiding spout connections, main injection jet is arranged on the inboard partially root of rectangular notch, and some guiding spouts are separately positioned on the medial surface of fixed block, and is positioned at the intersection that weft yarn grips air admission hole and weft yarn gripping hole.
The utility model has the advantages that: simple in structure, manufacturing cost is lower; When cord fabric is weaved, can effectively control the forming quality of its selvedge; Use reliable and stable, easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing the utility model air-jet loom selvedge device is described in further detail:
Fig. 1 is the structure chart of the utility model air-jet loom selvedge device (left side);
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, fixed block, 2, the V-arrangement opening, 3, rectangular notch, 4, the support fixing hole, 5, weft yarn grips air admission hole, and 6, weft yarn grips the hole, 7, weft yarn sprays into air admission hole, 8, main injection jet, 9, guiding spout, 10, weft yarn sprays into auxiliary inlet port, 11, auxiliary spout.
The specific embodiment
As illustrated in fig. 1 and 2, structure chart for a kind of air-jet loom selvedge device left side, comprise a fixed block 1, the front side of fixed block 1 offers V-arrangement opening 2, the root of V-arrangement opening 2 offers rectangular notch 3, be provided with support fixing hole 4 above the fixed block 1, offer weft yarn between the end face of fixed block 1 and the rectangular notch 3 and grip air admission hole 5, corresponding with it, offer weft yarn between the back downside of rectangular notch 3 and fixed block 1 and grip hole 6, offer weft yarn in fixed block 1 inside of weft yarn gripping air admission hole 5 rear sides and spray into air admission hole 7, weft yarn sprays into air admission hole 7 and is communicated with a main injection jet 8 and four guiding spouts 9 respectively, main injection jet 8 is arranged on the inboard partially root of rectangular notch 3, four guiding spouts 9 are separately positioned on the medial surface of fixed block 1, and be symmetricly set on weft yarn and grip the intersection that air admission hole 5 and weft yarn grip hole 6, above-mentioned weft yarn sprays into and also offers weft yarn in the fixed block 1 of air admission hole 7 rear sides and spray into auxiliary inlet port 10, weft yarn sprays into auxiliary inlet port 10 and is connected with auxiliary spout 11, and auxiliary spout 11 is positioned at the medial surface of fixed block 1, and be positioned on the same horizontal line with rectangular notch 3.
In the utility model, above-mentioned selvedge device is the both sides that are installed in jet cord fabric loom in pairs symmetrically.When reality is used, weft yarn also can be set on the above-mentioned fixed block 1 spray into auxiliary inlet port 10 and auxiliary spout 11, but the selvedge device of this structure to be in use, the stability of its selvedge and reliability outline difference are a little; In addition, above-mentioned guiding spout 9 quantity can certainly, also can have more a plurality of guiding spouts 9 to be symmetricly set on the intersection that weft yarn grips air admission hole 5 and weft yarn gripping hole 6 between 2 to 4 usually.
When jet cord fabric loom was worked, this selvedge device was pressed the preset function parameter and is worked asynchronously with main frame.The weft yarn of above-mentioned selvedge device grips air admission hole 5, weft yarn and sprays into air admission hole 7 and weft yarn and spray into auxiliary inlet port 10 and be connected with controlled compressed air respectively, when weft yarn with the Loom reed forward swing to the weft yarn passage, be in the rectangular notch 3 time, weft yarn grips air admission hole 5 and does regularly air inlet, and by weft yarn gripping hole 6 the weft yarn time-delay is gripped; When putting certain position after reed is by front center, weft yarn sprays into auxiliary inlet port 10 air feed when making fixed response time, and compressed air sprays into fell from auxiliary spout 11 ejections in advance with the weft yarn middle part; This moment, weft yarn sprayed into air admission hole 7 air feed when making fixed response time, compressed air sprays from main injection jet 8 and four guiding spouts 9, weft yarn grips air admission hole 5 and does regularly to close, discharge weft yarn, at this moment, continue weft yarn is sprayed into fell by main injection jet 8, guiding spout 9 and auxiliary spout 11, regularly close then that weft yarn sprays into air admission hole 7 and weft yarn sprays into auxiliary inlet port 10, thereby finish a selvedge action, so go round and begin again, move in circles.When loom quits work into, this selvedge device also stops action.
