Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Novel quantitative yarn-feeding device, comprise warp beam 1, frame (not shown), winding roller 14, Controlling System, the axial two ends of warp beam 1 are arranged in frame, winding yarn 4 in warp beam, warp beam 1 is connected with warp let-off step-down gear 8, warp let-off step-down gear 8 is connected with motor one, motor one is preferably warp let-off servomotor 9, warp let-off servomotor 9 drives warp beam 1 to rotate, step-down gear 15 is connected winding roller 14 with batching, batch step-down gear 15 to be connected with motor two, motor two is servomotor 16 preferably, motor two drives winding roller to rotate, the speed of winding roller is adjusted by batching step-down gear 15, between winding roller 14 and warp beam 1, quantitatively send deflector roll 5, quantitatively send action roller 6, the axial two ends of pressure roller 7 are quantitatively sent to be arranged in frame by bearing, wherein quantitatively send deflector roll 5, quantitatively send pressure roller 7 respectively with quantitatively to send action roller 6 tangent, and quantitatively give action roller to be positioned at quantitatively to give deflector roll, quantitatively send between pressure roller, make quantitatively to send deflector roll 5, quantitatively send action roller 6, the center line of pressure roller 7 three is quantitatively sent to form the structure of a trilateral, in order to threading is convenient, quantitatively send deflector roll 5 and quantitatively send pressure roller 7 energy movable, quantitatively send deflector roll 5 and quantitatively send pressure roller 7 to increase yarn and quantitatively send the cornerite on action roller 6, step-down gear 10 is connected with quantitatively sending quantitatively to send pressure roller 7, step-down gear 10 is quantitatively sent to be connected with motor three, motor three preferably quantitatively send servomotor 11, by quantitatively sending step-down gear 10 to adjust the rotating speed quantitatively sending action roller. in order to increase the frictional force of yarn and roller, quantitatively sending deflector roll, quantitatively send action roller, quantitatively send pressure roller all adheres to rubber, increase the frictional force of yarn.
Warp beam 1 and quantitatively send and be also provided with tensioning roller 2 between action roller 6, the axial two ends of tensioning roller are arranged in frame by bearing, and the axial two ends of tensioning roller are socketed with adapter sleeve 17 respectively, adapter sleeve 17 is socketed on tensioning roller, lower end at adapter sleeve connects tension force by bearing and shakes roller 3, or tension force shakes the lower end that roller 3 is directly fastened on adapter sleeve, and sensor 12 is installed in one end of tensioning roller simultaneously, sensor 12 arranges sensor contact block 13, the tension force of sensor contact block 13 perception yarn.
Controlling System is electrically connected with motor one, motor two, motor three respectively or signal is connected, and Controlling System has the receiver module of receiving sensor contact block 13 signal.
According to batch the reduction ratio of step-down gear, winding roller diameter, quantitatively send the diameter of action roller and quantitatively send the reduction ratio of step-down gear, in the controls, the rotating speed quantitatively sending servomotor 11 is set by a certain percentage and batches the rotating speed of servomotor 16.
In the present invention, quantitatively sending servomotor to drive quantitatively send action roller first to rotate, action roller is quantitatively sent to rotate tension yarn, when yarn is tightened up, tensioning roller and quantitatively send yarn tension between deflector roll to become big, tension force shakes roller pullling by yarn, then tension force shakes roller 3 and rotates to an angle centered by tensioning roller 2, at this moment, sensor 12 is by sensor contact block 13, signal is passed to warp let-off servomotor 9 by Controlling System, warp let-off servomotor 9 rotates, warp beam 1 warp let-off (namely sending yarn) is driven by warp let-off step-down gear 8, when the yarn amount of reaching sent, warp beam stops rotating, when the tension force quantitatively sending action roller experienced again by tensioning roller by yarn, warp beam rotates the warp let-off again, so circulation is repeatedly.
Use the length of yarn sent in the unit time of the present invention uniform and stable, when being used in loom for weaving double-layered flannelette or carpet, it is possible to reach and quantitatively send suede yarn, make the product suede height woven evenly constant.
These are only the better embodiment of the embodiment of the present invention; not in order to limit the embodiment of the present invention; within all spirit in the embodiment of the present invention and principle, any amendment of doing, equivalent replacement, improvement etc., all should be included in the protection domain of the embodiment of the present invention.
