[0026] Working principle:

[0027] When elastic buffering protection is required for the warp knitting machine's thread group:

[0028] Buffer roller adjustment stage:

[0029] The operator pulls one end of the line group 9 through the guide roller 6, the first buffer roller 7 and the second buffer roller 8 in sequence. When the tension of the line group 9 is large, the operator turns the first knob 301, the first knob 301 drives the first rotating rod 302 to rotate, the first rotating rod 302 drives the roller 303 to rotate, the roller 303 drives the slider 304 to move through the surface-processed slide groove, the slider 304 drives the slide plate 305 to move, the slide plate 305 drives the support block 306 and the first buffer roller 7 to move, the support block 306 drives the guide rod 307 to move, the guide rod 307 drives the lifting block 310 to move, the lifting block 310 drives the second buffer roller 8 to move, and the buffer spring 309 enables the second buffer roller 8 to be lifted and lowered in a small range to buffer the line group 9. When the first buffer roller 7 and the second buffer roller 8 move to the appropriate position, the operator stops turning the first knob 301 and screws the bolt into the base 2 so that the bolt is pressed against the roller 303. This increases the distance between the two buffer rollers and the guide roller 6, so that the wire group 9 can be kept in a taut state.

[0030] Reel replacement phase:

[0031] When all the wire groups 9 wound on the surface of the wire wheel 5 are released, the operator turns the second knob 401, the second knob 401 drives the second rotating rod 402 to rotate, the second rotating rod 402 drives the cam 403 to rotate, the cam 403 drives the moving block 404 to move, the moving block 404 compresses the spring 406 and drives the moving seat 405 to move, after the moving seat 405 is no longer in contact with the wire wheel 5, the operator stops turning the second knob 401 and replaces the wire wheel 5 so that the wire wheel 5 wrapped with the wire group 9 is clamped on the moving seat 405, and then the operator continues to turn the second knob 401. Through the above method, the moving seat 405 can drive the wire wheel 5 to press against the bracket on the surface of the base 2, which eliminates the need for the operator to rewind the new wire group 9, thereby completing the wire-releasing work of the elastically buffered telescopic limit protection warp knitting machine.
