Description
The utility model relates to a kind of picking mechanism of loom, be meant the picking mechanism of rapier shuttleless loom especially, belong to field of textile machinery.
The picking mechanism of at present common shuttle-free loom sees shown in Figure 1, and it includes: one is fixedly connected on the belt gear 102 on the power transmission shaft 101, through odontoid belt 113 and 114 transmissions, one crank gear 103; Other has linking arm 104 and ship shape link arm 105 to be connected on the crank of crank gear 103, and the other end then is connected on the odontoid belt 106; Odontoid belt 106 hangs on the gear-box 107; Inner gear of the gear box 108 is subjected to odontoid belt 106 the transmissions dual gear train 109 of transmission, gear 111 again; Gear 108 is an external gear in the split with gear 111, and the axle of gear 111 has an arrow shaft gear 112 by the aperture of gear 108 on the other end, and this arrow shaft gear is the rapier type shuttleless loom picking mechanism of an integral body of transmission arrow shaft group 110 formation again.Above working process of mechanism is: the belt gear 102 of power transmission shaft 101 by being connected on it, come driving crank gear 103 to rotate through odontoid belt 113 and odontoid belt 114, linking arm 104 and ship shape link arm 105 1 ends are connected on the crank of crank gear 103, and the other end is connected on the odontoid belt 106; So linking arm 104 and ship shape link arm 105, odontoid belt 106 can move up and down when crank gear 103 rotates; Odontoid belt 106 is hung on gear-box 107 and the toothed belt wheel of gear 108 with one again, and gear 108 transmission bidentate wheels 109 are passed gear 111 again back, and axle one end of gear 111 is an arrow shaft gear 112; Because pumping of odontoid belt, relative transmission arrow shaft gear 112 is made positive de-rotation, to reach the picking movement of the arrow shaft group that places on the arrow shaft gear.But the picking mechanism of above-mentioned structure is too complicated as a whole, thereby forms too many parts changeover mechanism; Again because crank gear 103, linking arm 104, the weight of ship shape arm 105 and gear-box 107 integral body is heavier, in rotation at a high speed and reciprocating motion, transmission, switching, can cause the significant load noise of parts; Because of above-mentioned whole mechanism, its transmission and turning point cause reciprocating play tolerance too much again, the linking of picking weft yarn is had the unsettled possibility of missing, thereby cause the rare close lane of loom weft density phenomenon.
The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, and a kind of noise that improves is provided, and reduces fault rate, makes mechanism's smooth operation smooth and easy, and then can improve the rapier shuttleless loom picking mechanism of woven product quality.
The purpose of this utility model is finished by following technical solution, promptly adopt following transmission mechanism, it include with loom in the lay sword that bent axle is connected that beats up, there is an end of a gear spindle to be connected on the lay sword, be attached with a belt gear and tension adjustment wheel on it respectively, the other end is connecting gear-box, article one, odontoid belt is hanged up in the belt gear on the lay sword, tension adjustment wheel and is placed on front and back two straining pulleys on the loom wall, is connected with odontoid belt by a swing arm again on the lay sword.
Swing arm described in the utility model is the rotating support point with the axle that is fixed on the loom machine wall, and it is not held by a connecting rod and is connected on the odontoid belt, and the other end then has a connecting rod to be connected in lay sword.
The utility model also can be provided with two adjusting fixed screws with the connecting rod that connects between swing arm and the lay sword, makes it to become an adjustable connecting-rod.
90 ° of outputs that gear-box described in the utility model includes two bevel gear engagements become a kind of steering box.
Description of drawings is as follows:
Fig. 1 is the structural representation of correlation technique.
Fig. 2 is a structural representation of the present utility model.
To be described in detail the utility model by accompanying drawing below: have a lay sword 206 to be subjected to the rotation of loom beating-up bent axle 201 own and through connecting hand in hand 204 and affecting of connecting plate 205 and reciprocating, it has rotating shaft 222, drives and the bent axle 201 that beats up is rotations by application of force motor 202 and belt pulley 203; An end of gear spindle 208 serves as the rotation strong point with steering box 207 again, the other end serves as the rotation strong point with lay sword 206 then, belt gear 210 is a fixed axis with above-mentioned gear spindle 208 then, be arranged at lay sword 206 1 sides, also be provided with tension adjustment wheel 216 simultaneously, and serve as to swing the strong point with gear spindle 208; Posttension wheels 213 and toe-out wheels 214 are supporting base with loom machine wall 215 respectively, are placed on the front and back machine wall 215 of lay sword 206, and an odontoid belt 217 is hanged up on toe-out wheels 214, tension adjustment wheel 216, belt gear 210 and posttension wheels 213; When the bent axle 201 of beating up rotate and by connect hand in hand 204, when connecting plate 205 affects lay sword 206 to make front-rear reciprocation movement, odontoid belt 217 can make belt gear 210 produce positive de-rotation, and the tension force of odontoid belt 217 is regulated in tension adjustment wheel 216 meetings this moment automatically.Have one to regulate connecting rod 219, the one end connects lay sword 206 by bearing pin 224, it is the swing arm 218 of supporting-point with the axle on the loom machine wall 215 223 that the other end is then regulated fixed screw 225 connections by two, change by regulating the link position of connecting rod 219 in swing arm 218, can adjust the variation of odontoid belt 217 reciprocating motion traverses, thereby adjust the rotating cycle of belt gear 210, can reach the traverse requirement of arrow shaft group 212 like this, obtain due picking length requirement.Not end in swing arm is connected in odontoid belt 217 by a connecting rod 220, when above-mentioned swing arm 218 is swung by lay sword 206 drives by regulating connecting rod 219, then be attached thereto odontoid belt 217 and also can be subjected to transmission and do just backward rotation and then drive belt gear 210 positive de-rotation; Link to each other with steering box 207 on being fixed in lay sword 206 at the other end of gear spindle 208, positive de-rotation by above-mentioned belt gear 210 is passed through gear spindle 208, then by steering box 207, make the arrow shaft gear 211 that is fixed on steering box 207 output shafts make crankmotion, and drive position arrow shaft group 212 is thereon done reciprocal picking campaign thereupon.There are a large umbrella gear 209 and small umbrella gear 221 to be meshing with each other in the described steering box 207, thereby constitute the steering box of speed change.According to the controllability of belt gear 210 turning collars recited above, make the traverse of sword belt group 212 obtain the requirement of due picking length relatively.
The utility model is owing to utilized the reciprocating motion of lay sword, and come uni-drive gear box to implement the picking function of arrow shaft group by a tooth belt, therefore will accumulate free tolerance on overall construction design reduces to minimum, can in the linking of picking, obtain best situation, and in the high-speed motion process of mechanism, can reduce to minimum to various motion drags, can keep motion smoothly, noise can be reduced to minimum, have simple and compact for structure, can obviously improve noise, reduce the loss fault, and can improve characteristics such as fabric product quality.
