Embodiment 1
[0034] Such as figure 1 Shown is a typical tension fluctuation curve.
[0035] figure 1 It is on the KS4-EL warp knitting machine, only GB2 is used, 83.3dtec polyester low elastic yarn is fully worn, the lapping weave is 1-0 / 1-2 / / , and the let-off is 1320mm / rack. The tension fluctuation obtained from the test curve.
[0036] From figure 1 It can be seen that the main peak appears in the range of 100°-250° of the main axis, and the maximum, minimum and average value of the tension value can be read.
[0037] The relationship between △θ and △H is: △θ=△H / R, where R is the length of the steel plate;
[0038] The relationship between △a and △i is: △a=k·△i, where k is a constant term.
Embodiment 2
[0040] Such as figure 2 As shown, it is a schematic diagram of functional components of warp knitting positive tension compensation device, including: motor drive device 1, coupling 2, rigid tension rod 3-1, steel plate 3-2, shaft 3-3, bearing seat 4; Described bearing seat 4 can be installed on the frame of warp knitting machine, and described bearing seat 4 is sleeved with shaft 3-3, and one end of described shaft 3-3 is provided with coupling 2, and described shaft coupling 2 The other end is provided with a motor drive device 1, and the coupling 2 is connected to the shaft of the motor drive device 1; the rigid tension rod 3-1 is connected to the shaft 3-3 through a steel plate 3-2.
[0041] Such as image 3Shown is the warp-knitted positive compensation device and its working flow chart of the present invention. The warp knitting positive tension compensation device includes a motor drive device 1 and a rigid tension rod 3-1; the motor drive device 1 drives and control...
