The let-off motion of the rapier loom is characterized in that the stepless gear box (2) is connected with two change speed wheels (3) by a transmission device; a variable speed belt (4) is connected between the change speed wheels; the change speed wheels are meshed with let-off worm gears (6) by let-off worms (5); the let-off worm gears are coaxially fixed with let-off pinions (7); the let-off pinions are meshed with let-off gearwheels (8); the let-off gearwheels are fixed with driving shafts (9); and the wallboard is also provided with a tension roller (10).
Description
Technical field
The utility model relates to a kind of textile machine, especially relates to a kind of to the isostructural improvement of Rapier looms let-off motion.
Background technology
Loom is as a kind of ancient machinery, after entering current society, no longer independent is the service of wearing the clothes, and it is to field developments in pluralism such as industry, military affairs.Therefore, loom many special requirements have been proposed, the manufacturing of loom has also become many specifications, the product of small lot, and at present popular high speed Rapier looms adopts basically is on a left side, the frame structure outside suspension comprehensive power distribution case that right wallboard and lateral member are formed, also be provided with on this frame structure and beat up, wefting insertion, batch, the warp let-off, mechanisms such as opening, when weaving, the work of comprehensive dynamic distributor box, thereby realize beating up, wefting insertion, batch, the warp let-off, the unified motion of mechanisms such as opening, though this structure simplicity of design, intensity is suitable, but the transmission distributor box of its let-off motion is made complicated, the cost height, and it is bigger to exist the flexible difficulty of its loom, the problem that accommodation is little.
The utility model content
The utility model technical issues that need to address provide a kind of Rapier looms let-off motion, it mainly is that the transmission distributor box that solves existing in prior technology Rapier looms let-off motion is made complexity, cost is high, and it is bigger to exist the flexible difficulty of its loom, the technical problem of the little grade of accommodation.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Rapier looms let-off motion of the present utility model, comprise wallboard, wallboard is provided with infinitely variable transmission, it is characterized in that described infinitely variable transmission is connected with two change pulleys by transmission device, be connected with variable velocity zone between the change pulley, change pulley has warp let-off worm gear by warp let-off worm engaging, the coaxial warp let-off pinion that is fixed with of warp let-off worm gear, warp let-off pinion has warp let-off gear wheel, and warp let-off gear wheel is fixed with beam of a loom, also is provided with jockey pulley on the wallboard.Infinitely variable transmission can be communicated with motor, after motor starts, drive change pulley and rotate by infinitely variable transmission, transmission device, thereby change pulley is transferred to warp let-off worm screw, warp let-off worm gear with power, beam of a loom on the warp let-off this moment gear wheel can batch warp, jockey pulley can make warp have certain force of strain in transport process, makes things convenient for Rapier looms to weave cotton cloth.
As preferably, described wallboard is hinged with rocking arm; rocking arm one end is fixed with shift fork; the other end is hinged with adjusting screw(rod); the movable block that has been threaded on the adjusting screw(rod), and movable block is hinged with tension arm, and the tension arm middle part is hinged on the stator; stator is fixed on the wallboard, and the tension arm outer end connects jockey pulley.Shift fork and rocking arm are formed " L " type, stir shift fork, drive rocking arm and shake, thereby drive the tension arm swing by adjusting screw(rod), therefore can adjust the position of jockey pulley, and then adjust the tension force of warp.Movable block also can be adjusted the position on adjusting screw(rod), thereby adjusts the tension force of warp.
As preferably, described transmission device includes first gear that is connected with infinitely variable transmission, and first gear is engaged with second gear by change gear, and second gear is connected with change pulley by worm and gear.Change gear is made up of the two-layer gear of notch cuttype, two-layer respectively with first gear, second gears engaged, transmission is comparatively tight.
Therefore, the transmission distributor box that the utlity model has the let-off motion in the Rapier looms is easily manufactured, cost is lower, and can be applied to most of Rapier looms, characteristics such as flexible difficulty is less, and accommodation is big, and is simple and reasonable for structure.
