Abstract
The invention provides a yarn tension control device of a warp knitting machine, comprising a yarn guide rod supported by a frame, a tension rod, a yarn guide cap, and a control component corresponding to each guide bar, wherein the control component comprises a tension spring, a limit switch, a comb chain wheel and a restoring spring; the comb chain wheel is fixed on the tension rod and is connected with the lower end of the restoring spring through a chain; the upper end of the restoring spring is fixed on the frame; the middle part of the tension spring is connected with the tension rod; and two ends of the tension spring are connected on the yarn guide cap. The yarn tension control device of the warp knitting machine is characterized in that the tension rod is provided with a limit cam wheel; the lower part of the limit cam wheel is provided with a notch, and the switch shifting rod end of the limit switch extends into the notch of the limit cam wheel. When the device is used, if the yarns are too tight or too loose, the warp knitting machine is stopped automatically, and the problem of regulating the limit distance in the existing yarn tension control device is avoided.
Description
Technical field
The present invention relates to the warp loom yarn tension control device.
Background technology
For keeping yarn that a constant tensile force is arranged all the time, make yarn carry steadily, prevent to take place because of the phenomenon that the yarn tension tension causes knitting needle to fracture, yarn tension control device is set on the warp knitting machine.See Fig. 9; yarn tension control device comprises lever jack and tension rail 3; also comprise limit switch 7 and the Tension Control dish 16 that is fixed on the tension rail 3, the Tension Control dish is the racket shape, and the driving lever of limit switch is in the shank side of Tension Control dish; the circumferential surface that yarn is pasting the Tension Control dish passes through; along with the variation of yarn tensile force, the Tension Control dish is constantly swung, when yarn tension excessive; the shank of Tension Control dish touches the driving lever of toggle switch, and warp knitting machine is shut down.Because the control of yarn tensile force size realizes that by the shank of adjustment Tension Control dish and the spacing distance h between the driving lever spacing distance is too little, often shuts down; influence production efficiency; spacing distance is big, and yarn tension control device does not play effect, influences product quality.Existing tenslator have only one spacing, promptly can autostop during the yarn tension, but loose excessively, then uncontrollable when yarn, and the spacing distance between the shank of Tension Control dish and the limit switch driving lever do not have benchmark, adjusting is difficult.
Summary of the invention
The objective of the invention is to propose a kind of tension adjustment convenience and the warp loom yarn tension control device that can shut down is automatically all arranged when yarn is too tight or too loose.
For achieving the above object, the present invention takes following technical scheme: the present invention includes the lever jack by rack support, tension rail and guide cap, also comprise the Control Component that corresponding each sley bar is provided with, described Control Component comprises tension spring, limit switch, cockscomb sprocket wheel and back-moving spring, described cockscomb sprocket wheel is fixed on the tension rail, the cockscomb sprocket wheel is connected with the lower end of described back-moving spring by chain, the upper end of back-moving spring is fixed on the frame, the middle part of described tension spring is connected with tension rail, the two ends of tension spring are connected on the guide cap, be fixed with limit cam on the described tension rail, the bottom of limit cam has a breach, and the switch driving lever termination of described limit switch is stretched in the breach of limit cam.
Described guide cap has longitudinal opening, and the two ends of described tension spring are connected on the short column, and the short column of tension spring embeds in the guide cap by the longitudinal opening of guide cap.
The present invention has following good effect.The present invention adopts the limit cam with breach to substitute Tension Control dish of the prior art; under the yarn tension effect, limit cam is constantly swung, when yarn too tight or too loose; a wherein wall of two walls of the breach of cam can touch the driving lever termination of limit switch, and warp knitting machine promptly can autostop.Since the spacing length of the breach of limit cam according to the yarn compensation rate by calculating, so concerning limit cam, the length of breach is fixed, so there is not the adjusting problem that needs in the existing yarn tension control device spacing distance.

The specific embodiment
(embodiment 1)
See Fig. 1 to Fig. 8, present embodiment comprises lever jack 2, tension rail 3 and the guide cap 4 by frame 1 supporting, also comprises the Control Component that corresponding each sley bar is provided with.Lever jack 2, tension rail 3 and guide cap 4 and machine are wide.Control Component comprises tension spring 5, limit cam 6, limit switch 7, cockscomb sprocket wheel 8 and back-moving spring 9.Above-mentioned limit cam 6 and cockscomb sprocket wheel 8 are fixed on the tension rail 3,
The lower end of described chain 10 is connected the bottom of cockscomb sprocket wheel 8, and the upper end of chain 10 is connected with the lower end of described back-moving spring 9, and chain 10 middle parts are attached on the periphery of cockscomb sprocket wheel 8.The upper end of back-moving spring 9 is fixed on the back-moving spring bracing frame 1-1 of frame.Back-moving spring 9 plays the adjustment of tonicity size.
The middle part of described tension spring 5 is connected with tension rail 3, and the two ends of tension spring 5 are connected on the short column 5-1, and guide cap 4 has longitudinal opening 4-1, and the short column 5-1 of tension spring 5 embeds in the guide cap 4 by the longitudinal opening of guide cap 4.Limit switch 7 is fixed on the frame.
The bottom of described limit cam 6 has an arc notch 6-1, the switch driving lever termination 7-1 of described limit switch 7, and the termination 7-1 of switch driving lever stretches among the breach 6-1 of limit cam 6.
See Fig. 7 and Fig. 8, lever jack 2 walked around by the yarn 12 of drawing from coiled hair 11 and guide cap 4 passes sley point, when the yarn tensioning, drives limit cam and rotates counterclockwise, and when yarn is relaxed, is subjected to the effect of back-moving spring 9, and limit cam clockwise rotates.When yarn was too tight or too loose, the left wall of the breach of limit cam or right wall just can touch the driving lever termination of limit switch, and main motor shuts down, and warp knitting machine is shut down.
