Abstract
The utility model discloses a let-off mechanism of a multi-bar Raschel machine, which comprises a plurality of pattern warp beams, wherein the pattern warp beams are parallel to one another and are rotationally mounted on the multi-bar Raschel machine; warp yarns are unwound from the pattern warp beams and sent to steel-bar pattern combs to be woven; the steel-bar pattern combs comprise a jacquard steel-bar pattern comb for jacquard weave and a serging steel-bar pattern comb for serging; the pattern warp beams, through which the warp yarns are sent to the serging steel-bar pattern comb, are driven to rotate by driving devices; the driving devices are motors preferably; the pattern warp beams, through which the warp yarns are sent to the serging steel-bar pattern comb, are two and are driven to rotate by the motors through transmission mechanisms; and each transmission mechanism comprises a pair of gears which are meshed with each other and connected with the output shaft of the corresponding motor and one end of the corresponding pattern warp beam. In a weaving process, the tension of warp yarns for serging is stable and cannot change with the change of the weaving speed; and the warp yarns for serging stop reliably, so that woven patters are beautiful and lifelike.
Description
Technical field
The utility model relates to a kind of warp-feeding mechanism of warp knitting machine, particularly relates to a kind of warp-feeding mechanism of many comb Raschel loomss.
Background technology
The warp-feeding mechanism of existing many comb Raschel loomss; Comprise some be parallel to each other and be installed in rotationally on the warp knitting machine frame the flower through the axle; Each flower rotates under the tension of warp thread through axle; Making warp thread go up unwinding from flower through axle continuously delivers to steel bar flower comb and weaves the lock seaming steel bar flower comb that steel bar flower comb comprises the jacquard weave steel bar flower comb that is used for jacquard weave and is used to lockstitch a border.The warp-feeding mechanism of this structure; Because flower warp axle is particularly delivered to spending through axle of lock seaming steel bar flower comb with warp thread and adopted the passive type warp let-off, thereby when braiding speed changes; Average tension on warp is bigger; And when the lock seaming average tension on warp that is used to lockstitch a border is big, then cause the serious distortion of flower type, thereby reduce fabric quality greatly.
Summary of the invention
The technical problem that the utility model will solve provides a kind of in the braiding process, and the tension stability of lock seaming warp thread can not change with the variation of braiding speed, and the warp-feeding mechanism of reliably a kind of many comb Raschel loomss of lock seaming warp thread stop.
For solving the problems of the technologies described above; The utility model adopts the warp-feeding mechanism of so a kind of many comb Raschel loomss; Comprise some be parallel to each other and be installed in rotationally on the warp knitting machine the flower through the axle; Warp thread is gone up unwinding from each flower through axle and is delivered to steel bar flower comb and weave, the lock seaming steel bar flower comb that said steel bar flower comb comprises the jacquard weave steel bar flower comb that is used for jacquard weave and is used to lockstitch a border, and the said flower that warp thread is delivered to lock seaming steel bar flower comb is driven by drive unit through axle and rotates.
The said flower that warp thread is delivered to lock seaming steel bar flower comb has two through axle, and these two flowers are driven by drive unit respectively through axle and rotate.
Said drive unit is preferably motor, and the said flower of warp thread being delivered to lock seaming steel bar flower comb is driven through transmission mechanism by motor through axle and rotates.
Said transmission mechanism can be made up of the gear of pair of meshing, and this links to each other with the output shaft of said motor and an end of Hua Jing axle respectively to gear.
After adopting such structure; Because warp thread being delivered to the flower of lock seaming steel bar flower comb is rotated by the drive unit driving through axle; The flower of the utility model is preferably rotated by gear drive by motor through axle; Therefore, in the braiding process, what the flower of warp thread being delivered to lock seaming steel bar flower comb adopted through axle is the initiatively warp let-off; The positive type warp let-off in other words; Thereby the tension force of lock seaming warp thread can not change along with the variation of braiding speed, and keeps stable state, thereby makes colored type attractive in appearance undistorted; In addition, when motor stopped operating, the flower that is rotated by motor-driven stopped operating through axle simultaneously, therefore, the motor stall, flower stops the warp let-off immediately through axle, guaranteed the lock seaming warp thread reliably stop stop braiding, thereby make fabric quality better.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to specify.
Fig. 1 is a kind of structural representation that the utility model is combed the warp-feeding mechanism of Raschel looms more, transmission mechanism not shown in the figures.
Fig. 2 is the right view of Fig. 1, and shown in the figure is gear drive.
The specific embodiment
Warp-feeding mechanism referring to a kind of many comb Raschel loomss illustrated in figures 1 and 2; Comprise some be parallel to each other and be installed in rotationally on the warp knitting machine the flower through the axle 1; Warp thread is delivered to steel bar flower comb from the unwinding on axle 1 of each flower and is woven; The lock seaming steel bar flower comb that said steel bar flower comb comprises the jacquard weave steel bar flower comb that is used for jacquard weave and is used to lockstitch a border, the said flower of warp thread being delivered to lock seaming steel bar flower comb is driven by drive unit 2 through axle 1 and rotates.
In the utility model, the flower of warp thread being delivered to lock seaming steel bar flower comb has two through axle 1, and these two flowers are driven by drive unit 2 respectively through axle 1 and rotate, and are as shown in Figure 1; In addition, can be according to different braiding requirements, the said flower that warp thread is delivered to lock seaming steel bar flower comb can be one or have more than two through axle 1.
The drive unit 2 of the utility model is motor preferably, and the said flower of warp thread being delivered to lock seaming steel bar flower comb is driven through transmission mechanism 3 by motor through axle 1 and rotates.As shown in Figure 2, said transmission mechanism 3 is by the gear 3-1 of pair of meshing, and 3-2 constitutes; Said gear 3-1,3-2 link to each other gear 3-1 with the output shaft of said motor and an end of Hua Jing axle 1 respectively; The gearratio of 3-2 is preferably 1 ︰ 40; According to different braiding requirements, said gear 3-1, the gearratio of 3-2 can be different.In addition, said transmission mechanism 3 also can be synchronous band, wheel drive mechanism or other known transmission mechanism.
Like Fig. 1, shown in 2, the motor 2 in the utility model is installed in an end of step-like installing plate 4, and the other end of step-like installing plate 4 is installed on the connecting plate 5, and connecting plate 5 is fixedly connected on the warp knitting machine frame 6.The said flower that warp thread is delivered to lock seaming steel bar flower comb is installed on the bearing block 7 through bearing through an end of axle 1 rotationally.
The utility model process is on probation, the tension stability of lock seaming warp thread, and stop is reliable, and fabric flower type is attractive in appearance, has obtained good practical function.
