Usually, if we want to understand the functions of a device, we start from the functions of its various parts. The same is true of batch warping machines. What are the components and functions of each part! It is generally composed of the bobbin frame and the warping head: tension device, yarn breaking self-stop device, warp winding mechanism, warp pressing mechanism, brake device, length measurement and full shaft self-stop device.
Key points of batch warping machine for producing warp weaving shaft:
(1) Arrange the position of each color yarn package of each warp shaft on the warping frame according to the color warp arrangement sequence on the yarn dyed fabric shaft, so that after the warp shafts are combined on the sizing machine, the color yarn arrangement sequence basically conforms to the color warp arrangement sequence on the yarn dyed fabric. In order to reduce the number of cylinder changes and facilitate the later operation, the same color warp should be numbered in tandem when arranging the warp axis serial number. For example, there are 16 red yarn dyed fabrics The full cylinder yarn needs 12 warp shafts. At this time, two red yarn slips can be placed in the corresponding position basin of the warping frame. The 1st to 8th warp shafts are finished, or the 5th to 12th warp shafts are finished. There can be no serial number discontinuity in the middle. When merging the warp shafts on the sizing machine, the warp yarns shall be arranged according to the number of the warp shafts from the upper layer to the lower layer, and attention shall be paid to making the unwinding direction of each warp shaft consistent.
Sizing machine
(2) The warping can also be arranged according to the color of the warp. The same color yarn can be warped on one warp shaft or several warp shafts in series, and then the yarn is arranged in the order of the color warp arrangement on the dyed fabric at the expansion box in front of the sizing machine. If the number of warp threads of a certain color is too small or the number of warp threads of a certain color is too large but it is inconvenient to arrange, the two color warp threads can also be warped on the same warp axis. The above i-th yarn can also be discharged on the sizing machine for a second time.
(3) If the colors of a certain two color warp are similar, the strands shall be separated during warping and sizing. After the winding shaft is put on the loom, the strands shall be replaced with a stripper bar (located between the rear beam and the stoppers) to facilitate the operation of the on duty lathe operator.
