Description
Technical field
The present invention relates to the servicing unit of warp knitting machine, especially a kind of device of multi-functional adjusting jacquard comb yarn tension.
Background technology
Warp knitting machine is when running well, and yarn unwinding from coiled hair is got off, and the mechanism that sends into cam system according to certain warp run-in is called warp-feeding mechanism.Guaranteeing under the condition of normal lopping, it is accurate and constant that warp run-in should remain, yarn pushing tension is even.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 the too low Yarn relaxation that causes of minimum tension, 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, so yarn tension is all different.Thread-feeding amount and send the yarn time to send in yarn at jacquard comb to be all the key factor that affects fabric quality, to 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 type wrinkle is unfolded not open together.Even if yarn pushing tension regulates accurately, but send the yarn time to be not suitable for, weave the cloth coming also not attractive in appearance, so warp knitting machine in start process, the jacquard comb warp let-off is very important.Warp knitting machine is after start, and all sley bars and needle-bar are all in motion, and the yarn of Jacquard sley bar is when adjusting degree of tightness, because the reasons such as lifting and swinging of needle-bar all can impact pressure yarn effect, thus the quality of reduction fabric.For example, when warp knitting machine grooved-needle declines, the warp run-in of jacquard comb needs more loose, needs again tightlyer during rising, and when grooved needle bed swings forward, the warp run-in of jacquard comb needs pine, starts again tight during toward backswing.In a word, warp knitting machine thread-feeding amount is initiatively difficult to reach that Jacquard sley bar is needed uses yarn requirement, so warp knitting machine design when braiding can be restricted, is difficult to weave the design of beautiful Jacquard style.
Summary of the invention
Object of the present invention is just to provide a kind of device of multi-functional adjusting jacquard comb yarn tension, reduce the resistance of yarn tension, make even yarn tension stable, yarn is difficult for broken yarn, and send the yarn time to match with knitting cycle, be conducive to the lopping work of yarn.
In order to reach Jacquard sley bar, use yarn requirement each angle is needed, the present invention is achieved like this: described output line is connected to the control system of main electric cabinet, and described control system is mainly responsible for yarn feeding, the tractive of fabric of journal axle and is batched and main drive.It pads yarn exercise data by obtaining the colored type system from design centre, and converts them to every terms of information, the program setting is flowed to encoder simultaneously.The data such as the speed that described encoder rotates to main shaft according to programmed acquisition, angle, time send to driver, and described driver is converted into work order according to data, and instruction is flowed to servomotor.Described servomotor is according to the work order of receiving, execution work will begin in a minute.On the shaft of described servomotor, be connected with motor gear, described motor gear and auxiliary gear closely mesh, and yarn tension is tight or loose, by servomotor, drive the motor gear on shaft to rotate.When described motor gear rotates, drive the auxiliary gear on yarn passing rod to do forward and backward work, the rotation of auxiliary gear drives the rotation of tension spring and guide cap, finally realizes 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, has reduced the resistance of yarn tension, makes yarn be difficult for broken yarn, and walks around guide cap and weave for board.When yarn is close to after guide cap, send into looping mechanism for braiding lopping, at this moment control program is controlled motor according to the velocity of rotation of warp knitting machine main shaft and is carried out back rotation, and servomotor coordinates warp knitting machine lopping campaign, and control the degree of tightness of yarn tension, guarantee even yarn tension.Described servomotor assembling is simple, reduced the error that driving member is accumulated, and motor gear and auxiliary gear regulate the rotating speed of servomotor, making the adjusting 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 knitting out is good, and production efficiency is high.
Compared with prior art, usefulness of the present invention is: in this structure, regulate the tension force of yarn to realize according to warp knitting machine starting up speed, tractive coiling speed and weaving, by control system, encoder, driver and servomotor etc., realize.Design, reasonably structure and the very stable operation of a whole set of technology that this machine adopts based on hommization, the production system that it is up-to-date and meticulous maintenance work will make all precise parts of machine have permanent Production Life.Flow process of the present invention is simple, and work accurately, is not only used in the yarn-feeding device of Jacquard sley bar, also can be used on all sley bar yarn-feeding devices of warp knitting machine simultaneously, and be a kind of optimal selection that regulates yarn tension.
