Abstract
The utility model discloses a weft insertion mechanism that many in tube -shape fabric was weavingd, including actuating mechanism and drive mechanism, actuating mechanism includes servo motor and the speed reducer of being connected with servo motor, drive mechanism is including locating the cam on the speed reducer, the cam is connected to eccentric connecting rod one end, the eccentric connecting rod other end is connected to the initiative end of swing connecting rod, the swing end of swing connecting rod articulates to sector gear through the intermediate connecting rod for sector gear follows the pivot horizontal hunting, the meshing has gear transmission set spare on sector gear's the outer arc tooth, the meshing has long rack on the gear transmission set spare, long rack top such as is equipped with at two at least shuttles of interval distribution, the fixed short tooth strip that is equipped with in shuttle below, short tooth strip and long rack connect through gear engagement. The utility model discloses combine together weaving machines with shuttle's shuttle and shuttleless loom's wefting insertion kind of drive, weaving for many of the tube -shape fabric of realization on the loom.
Description
Technical field
The utility model relates to a kind of special mechanism of textile machine, is specifically related to one and can realizes several woven weft insertion devices of tubular fabric on loom.
Background technology
The wefting insertion of loom has mainly contained shuttle and without shuttle (comprising arrow shaft, jet, water spray and projectile shuttle etc.) two types, but the weft insertion system of this two types loom all can not meet tubular fabric several weave.The weft yarn of shuttleless loom is all discontinuous, therefore can not weave tubular fabric; The wefting insertion of fly-shuttle loom is, by shuttle, weft yarn is introduced shed open, shuttle is weft insertion device, again deposit latitude device, but its picking mechanism is the axle of throwing a spear driven by main transmission belt, realized by dish of throwing a spear, the strike such as side plate, picker stick shuttle of throwing a spear again, although weft yarn is continuous print, can only weave by single width.
Therefore, several how realizing tubular fabric are weaved, and are those skilled in the art's problems to be solved.
Utility model content
Goal of the invention of the present utility model is to provide several woven weft insertion devices of a kind of tubular fabric, the wefting insertion kind of drive of the shuttle of fly-shuttle loom and shuttleless loom is combined, and several realizing the tubular fabric on loom are weaved.
To achieve the above object of the invention, the technical solution adopted in the utility model is: several woven weft insertion devices of a kind of tubular fabric, comprise driving mechanism and transmission mechanism, the reductor that described driving mechanism comprises servomotor and is connected with servomotor, described transmission mechanism comprises the cam be located on reductor, described cam is connected to eccentric ratio one end, the described eccentric ratio other end is connected to the drive end of swing connecting bar, the swinging end of described swing connecting bar is hinged to sector gear through intermediate connecting rod, sector gear is swung along rotating shaft, the outer curved tooth of described sector gear is engaged with gear-driven assembly, described gear-driven assembly is engaged with long tooth bar, at least two shuttles be spacedly distributed are provided with above described long tooth bar, short tooth bar is fixed with below described shuttle, described short tooth bar is connected through gears meshing with long tooth bar.
Preferred technical scheme, described gear-driven assembly comprises the first gear be connected with a joggle with sector gear, the first coaxial profile of tooth belt wheel is installed with in described first gear, described first profile of tooth belt wheel is connected to the second profile of tooth belt wheel through belt, described second profile of tooth belt wheel outside is installed with the second coaxial gear, and described second gear and long tooth bar are connected with a joggle.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The wefting insertion kind of drive of the shuttle of fly-shuttle loom and shuttleless loom combines by the utility model, long tooth bar bilateral reciprocation is made through eccentric ratio, swing connecting bar, sector gear and gear-driven assembly successively by driven by servomotor cam, below gear driven, be installed with multiple shuttle reciprocating motions of short gear again by long tooth bar, thus several realizing tubular fabric are weaved.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation in embodiment one.
Wherein: 1, servomotor; 2, reductor; 3, cam; 4, eccentric ratio; 5, swing connecting bar; 6, intermediate connecting rod; 7, sector gear; 8, the first gear; 9, the first profile of tooth belt wheel; 10, belt; 11, the second profile of tooth belt wheel; 12, the second gear; 13, long tooth bar; 14, shuttle; 15, short tooth bar; 16, gear.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one: shown in Figure 1, a kind of several woven weft insertion devices of tubular fabric, comprise driving mechanism and transmission mechanism, the reductor 2 that described driving mechanism comprises servomotor 1 and is connected with servomotor, described transmission mechanism comprises the cam 3 be located on reductor, described cam is connected to eccentric ratio 4 one end, the described eccentric ratio other end is connected to the drive end of swing connecting bar 5, the swinging end of described swing connecting bar is hinged to sector gear 7 through intermediate connecting rod 6, sector gear is swung along rotating shaft, the outer curved tooth of described sector gear is engaged with gear-driven assembly, described gear-driven assembly is engaged with long tooth bar 13, at least two shuttles 14 be spacedly distributed are provided with above described long tooth bar, short tooth bar 15 is fixed with below described shuttle, described short tooth bar and long tooth bar are connected with a joggle through gear 16.
In the present embodiment, described gear-driven assembly comprises the first gear 8 be connected with a joggle with sector gear, the first coaxial profile of tooth belt wheel 9 is installed with in described first gear, described first profile of tooth belt wheel is connected to the second profile of tooth belt wheel 11 through belt 10, described second profile of tooth belt wheel outside is installed with the second coaxial gear 12, and described second gear and long tooth bar are connected with a joggle.
The utility model makes long tooth bar bilateral reciprocation through eccentric ratio, swing connecting bar, sector gear and gear-driven assembly successively by driven by servomotor cam, below gear driven, multiple shuttle reciprocating motions of short gear are installed with again by long tooth bar, therefore cop in shuttle and weft yarn enter warp thread shed open and complete whole wefting insertion process, thus several realizing tubular fabric are weaved.
In actual use, because the width of Woven fabric is different, the traverse of wefting insertion is also just different, when the change width of Woven fabric is little, can obtain desired traverse by the installation site changing swing connecting bar.
