DETAILED DESCRIPTION
[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0017] like Figure 1-Figure 2 As shown, the yarn auxiliary unwinding mechanism for warp knitted fabric production includes a column 1 for connecting to a warp knitting machine frame, specifically: the column 1 also has at least two connecting ears 2; a track 10 is vertically fixed on the column 1, an adjusting seat 12 is slidably connected to the track 10, a connecting platform 5 is fixed on the adjusting seat 12, a placing plate 6 for placing the bobbin is provided on the connecting platform 5, a limiting shaft 7 is vertically fixed on the placing plate 6, and the limiting shaft 7 can prevent the bobbin on the placing plate 6 from accidentally falling off; the placing plate 6 is connected to the lower end of a flexible bendable rod 20, a yarn guide ring 21 is connected to the upper end of the flexible bendable rod 20, and a locking member 13 is threadedly connected to the adjusting seat 12; in this embodiment, the traction transmission of the yarn at the bobbin on the placing plate 6 is driven by the warp knitting machine, that is, the yarn can be transported to the warp knitting machine together with the yarn on the disk head for weaving.
[0018] A guide block 18 is fixed on the connecting platform 5, and a movable rod 19 is vertically slidably connected to the guide block 18. The upper end of the movable rod 19 is connected to the placement plate 6, and the lower end of the movable rod 19 has a detection head 17. A spring 14 is also installed between the placement plate 6 and the guide block 18. A micro switch 16 that matches the detection head 17 is installed on the connecting platform 5, a warning light 9 is installed on the upper end of the column 1, and an electric control box 3 is also installed on the lower end of the column 1. The micro switch 16 and the warning light 9 are electrically connected to the electric control box 3 through a line. With this structure, in the early stage of unwinding, the weight of the bobbin is Under the action of force, the entire placement plate 6 is located at the lowest position. When the yarn on the bobbin is almost gone, due to the reduction in the weight of the bobbin, the placement plate 6 will be lifted upward under the elastic force of the spring 14. Finally, the detection head 17 is separated from the contact of the microswitch 16, and the signal is transmitted to the electric control box 3. The electric control box 3 controls the prompt light 9 to work, thereby reminding the operator to replace the bobbin. In the present embodiment, the microswitch 16 and the prompt light 9 are both electrically connected to the electric control box 3 through the line. This adopts the existing technology, and its circuit does not need to be redesigned.
[0019] A protective cover 15 is also installed on the connection platform 5 , and a micro switch 16 is arranged inside the protective cover 15 .
[0020] A reinforcement block 11 is further provided between the adjustment seat 12 and the connection platform 5 .
[0021] The locking member 13 is a thumb screw.
[0022] An upper limit block 8 is provided at the upper end of the track 10, and a lower limit block 4 is provided at the lower end of the track 10. Both the upper limit block 8 and the lower limit block 4 are rubber blocks.
[0023] In the utility model, when the warp knitted fabric is being knitted by the warp knitting machine, the bobbin is sleeved on the limiting shaft 7, the yarn on the bobbin passes through the guide wire ring and enters the warp knitting machine, and the entire bobbin is lifted upward along the track 10 by the adjusting seat 12, so that the entire bobbin is moved to a high position, that is, the position where the operator will not touch the bobbin when walking normally; the bobbin can unwind the yarn to the warp knitting machine, and at the same time, it will not affect the normal walking of the operator.
