Description
Technical field
The present invention relates to the servicing unit of warp knitting machine, especially a kind of device of multi-functional adjustment jacquard comb yarn tension.
Background technology
Warp knitting machine is when running well, and yarn gets off from unwinding coiled hair, and the mechanism sending into cam system according to certain warp run-in is called warp-feeding mechanism.Under the condition ensureing normal lopping, warp run-in should remain that yarn pushing tension is even accurately with constant.Too high mean tension and peak tension not only affect carrying out smoothly of warp knitting machine braiding process, also hinder appearance of fabrics; Mean tension is too low, can make that minimum tension is too low causes Yarn relaxation, makes yarn can not be close to loop-forming element and completes accurate lopping campaign.
Because jacquard comb plays jacquard weave effect in braiding, so yarn warp run-in is different, therefore yarn tension is all different.Thread-feeding amount is all the key factor affecting fabric quality with sending the yarn time to send in yarn at jacquard comb, and send yarn many, fabric broken yarn is many, patterns of fabric is unintelligible, plain; Send yarn few, fabrics cloth cover is too tight, and flower pattern wrinkle is unfolded not open together.Even if yarn pushing tension regulates accurately, but send the yarn time to be not suitable for, weave next cloth also unsightly, so warp knitting machine is in start process, the jacquard comb warp let-off is very important.After powering, all sley bars and needle-bar are all moving warp knitting machine, and the yarn of Jacquard sley bar, when adjusting degree of tightness, because reasons such as the lifting and swingings of needle-bar, all can impact pressure yarn effect, thus reduce the quality of fabric.Such as when warp knitting machine grooved-needle declines, the warp run-in of jacquard comb needs more loose, and need again relatively tighter during rising, when grooved needle bed swings forward, the warp run-in of jacquard comb needs pine, tight toward starting again during backswing.In a word, warp knitting machine thread-feeding amount is initiatively difficult to reach uses yarn requirement required for Jacquard sley bar, so warp knitting machine design when weaving can be restricted, is difficult to the design weaving beautiful Jacquard style.
Summary of the invention
Object of the present invention is just the device providing a kind of multi-functional adjustment jacquard comb yarn tension, reduce the resistance of yarn tension, even yarn tension is stablized, and yarn is broken yarn not easily, and send the yarn time to match with knitting cycle, be conducive to the lopping work of yarn.
Required for each angle, yarn requirement is used in order to Jacquard sley bar can be reached, the present invention is achieved like this: described output line is connected to the control system of main electric cabinet, the tractive of the feeding of the yarn of described control system primary responsibility journal axle, fabric and batching and main drive.It by obtaining pad yarn exercise data from the flower pattern system of design centre, and converts them to every terms of information, the program set is flowed to encoder simultaneously.Described encoder sends to driver according to programmed acquisition to the speed of main axis, angle, the data of time, and described driver is work order according to data transformations, and instruction is flowed to servomotor.Described servomotor is according to the work order received, and will begin in a minute execution work.The shaft of described servomotor is connected with motor gear, and described motor gear closely engages with auxiliary gear, and yarn tension is tight or loose, drives the motor gear on shaft to rotate by servomotor.When described motor gear rotates, drive the auxiliary gear on yarn passing rod to do forward and backward work, the rotating band dynamic tension spring of auxiliary gear and the rotation of guide cap, finally realize the control of jacquard comb yarn degree of tightness.
The rotation at the uniform velocity under the traction action of yarn of described yarn passing rod, the rotation of yarn passing rod, reduces the resistance of yarn tension, makes yarn not easily broken yarn, and walks around guide cap and weave for board.After guide cap is close to by yarn, send into looping mechanism for braiding lopping, at this moment control program controls motor according to the velocity of rotation of warp knitting machine main shaft and carrys out back rotation, and servomotor coordinates warp knitting machine lopping campaign, and control the degree of tightness of yarn tension, ensure even yarn tension.Described servomotor assembling is simple, decrease the error that driving member accumulation is got up, and motor gear and auxiliary gear regulate the rotating speed of servomotor, make the adjustment of yarn tension degree of tightness more accurate, and send the yarn time to match with knitting cycle, be conducive to the lopping work of yarn.The grey quality knit out is good, and production efficiency is high.
Compared with prior art, usefulness of the present invention is: regulate the tension force of yarn to realize according to warp knitting machine starting up speed, tractive coiling speed and weaving in this structure, realized by control system, encoder, driver and servomotor etc.The a whole set of technology that this machine adopts is based on the design of hommization, reasonably structure and very stable operation, and its up-to-date production system and meticulous maintenance work have permanent Production Life by making all precise parts of machine.Flow process of the present invention is simple, and work accurately, is not only used in the yarn-feeding device of Jacquard sley bar, and also can be used on all sley bar yarn-feeding devices of warp knitting machine, be a kind of optimal selection regulating yarn tension simultaneously.
