[0019] The hydraulic lifting system 2 includes an oil pump 2-1, an oil pump handle 2-2 and an oil circuit conversion valve 2-3. The hydraulic lifting system 2 controls both the lifting of the fabric beam bracket 3 and the lifting of the lifting device 4, and the working switch between them is completed by the oil circuit conversion valve 2-3.
[0020] The fabric beam bracket 3 includes a fork arm shaft 3-1, fabric beam fork arms 3-2, connecting rods 3-3 and a first hydraulic piston 3-4.
[0021] The fork arm shaft 3-1 is a hexagonal shaft, and its two ends are respectively rotatably connected to two connecting seats 15 through bearings.
[0022] There are a pair of weft beam fork arms 3-2, which are respectively slidably connected to the fork arm shaft 3-1 by hexagonal sleeves, so that they can be shifted left and right on the fork arm shaft 3-1 to adjust the fork arm positions for adapting to different weft widths of weft beams. The maximum weft width of the weft beams that can be stored in this embodiment is 2300 mm.
[0023] One end of the first hydraulic piston 3-4 is connected to the fork arm shaft 3-1 through a connecting rod 3-3, and the other end is connected to the oil circuit conversion valve 2-3 of the hydraulic lifting system 2 through an oil pipeline. In order to ensure balance, there are a pair of first hydraulic pistons 3-4, and correspondingly, there are also a pair of connecting rods 3-3. When the hydraulic lifting system works, a pair of first hydraulic pistons 3-4 drive a pair of connecting rods 3-3 to drive the fork arm shaft 3-1 to rotate, so as to drive a pair of weft beam fork arms 3-2 to lift.
[0024] The yarn tension control system includes a lifting device 4 and a yarn clamping device 5.

[0031] (1) First, remove the yarn clamping plate assembly 5-2, place the warp beam to be yarn-ironed on a pair of warp beam fork arms 3-2, and then fix both ends of the first yarn clamping plate 5-2-1 to the yarn clamping bracket 5-1 by screws.
[0032] (2) Then, two people cooperate to lead the warp beam yarn out from above the yarn stop lever 4-1 and down to the position of the first yarn clamping plate 5-2-1. Rotate the second yarn clamping plate 5-2-2 to clamp the yarn between the two yarn clamping plates, and lock it with the clamping screw 5-3 to complete the yarn clamping work.
[0033] (3) Next, the hydraulic lifting system 2 adjusts the height of the lifting device 4 to obtain appropriate yarn tension. When necessary, the hydraulic lifting system 2 raises and lowers the warp beam bracket 3 to lift the warp beam, thus completing the yarn preparation work.
[0034] (4) Finally, use the operating handle 14 to push the yarn rack cart to the working position of the yarn ironing machine and start the yarn ironing work.
