[0023] As Figures 1-7As shown in the figure, the present utility model provides a technical solution: a wire feeding device for a high-speed knitting machine, including a wire feeding frame 1. A wire feeding plate 2 is fixedly installed on the surface of the wire feeding frame 1. A motor 4 is fixedly installed on the surface of the wire feeding plate 2. The output shaft of the motor 4 is fixedly connected to the surface of a wire feeding wheel 3. The wire feeding wheel 3 is rotatably connected to the surface of the wire feeding plate 2. A support frame 5 is fixedly installed on the surface of the wire feeding frame 1. The inner wall of the support frame 5 is rotatably connected to the surface of a roller shaft 6. A support 7 is fixedly installed on the surface of the support frame 5. A control component 8 is arranged inside the support 7. The movable rod 801 can be folded. The pushing slide plate 86 moves horizontally in the support plate 84 under the support of a spring 85. After moving, the limiting rod 87 of the slide plate 86 is clamped into two groups of fixing rings 82, and the downward movement of the support plate 84 is restricted by a support block 88. This method can apply an appropriate pressing force to the knitting thread, avoiding the situation that the knitting thread breaks due to excessive tension of the knitting thread.

[0024] A vertical hole 9 is formed on the surface of the support 7. The vertical hole 9 can ensure the stable movement of the support rod 83 and the support plate 84. The control component 8 includes: a fixed rod 81, which is fixedly installed on the inner wall of the support 7. Fixing rings 82 are fixedly installed on the surface of the fixed rod 81. The distance between the fixed rod 81 and the fixing rings 82 can limit the movement of the support plate 84. The support 7 is penetrated by the support rod 83 and is slidably connected to the support rod 83. A support plate 84 is fixedly installed on the surface of the support rod 83. One end of a spring 85 is fixedly connected to the inner wall of the support plate 84. The other end of the spring 85 is fixedly installed on the surface of the slide plate 86. The slide plate 86 penetrates the support plate 84 and is slidably connected to the support plate 84. When the slide plate 86 is stressed, it can move horizontally in the support plate 84 under the support of the spring 85. The surface of the slide plate 86 is hinged to a limiting rod 87. A support block 88 is fixedly installed on the surface of the slide plate 86. One side of a torsion spring 89 is fixedly connected to the surface of the slide plate 86. The other side of the torsion spring 89 is fixedly installed on the surface of the slide plate 86. When the limiting rod 87 is touched, it can be folded under the support of the torsion spring 89. A pressing member 80 is further arranged inside the control component 8. The pressing member 80 includes: a movable rod 801, one end of the movable rod 801 is hinged to the surface of the slide plate 86, and the other end of the movable rod 801 is hinged to the surface of a vertical rod 802. The vertical rod 802 is fixedly installed on the surface of a support block 803. The inner wall of the support block 803 is rotatably connected to a cylinder 804. When the vertical rod 802 moves, the movable rod 801 can be folded to push the slide plate 86 to move. One end of a telescopic rod 805 is fixedly connected to the surface of the support block 803. The other end of the telescopic rod 805 is fixedly installed on the surface of the support plate 84. The surface of the support plate 84 is fixedly connected to the surface of an electric push rod 806. The electric push rod 806 is arranged on the inner wall of the support 7. The electric push rod 806 can push the support plate 84 to move longitudinally, and the support block 803 connected to the support plate 84 through the telescopic rod 805 moves synchronously.

[0025] In the present utility model, during use, the braided wire on the surface of the wire pay-off wheel 3 is passed through the surface of the roller shaft 6 and drawn out from within the support frame 5. After drawing, the braided wire is connected to the structure on the surface of the high-speed braiding machine. After connection, the electric push rod 806 within the driving support 7 is driven, and the electric push rod 806 pushes the support plate 84 downward. The support rod 83 fixed on the surface of the support plate 84 moves longitudinally within the vertical hole 9 opened on the surface of the support 7. When the support plate 84 moves, the support block 803 connected to the surface of the support plate 84 through the telescopic rod 805 slides downward synchronously. The cylinder 804 within the support block 803 continuously abuts against the surface of the braided wire. When the braided wire is pressed, the tension increases, and a reverse abutting force is exerted on the cylinder 804 and the support block 803. After the support block 803 is abutted, the telescopic rod 805 is squeezed, and the telescopic rod 805 contracts. When the support block 803 moves, the vertical rod 802 fixed on the surface of the support block 803 moves synchronously. When the vertical rod 802 moves, the movable rod 801 can be folded. The sliding plate 86 is pushed to move horizontally within the support plate 84 under the support of the spring 85. After movement, the sliding plate 86 snaps the limiting rod 87 into the two fixing rings 82, and the downward movement of the support plate 84 is restricted by the support block 88. This method can apply an appropriate pressing force to the braided wire, avoiding the situation where the braided wire breaks due to excessive tension. At the same time, during the movement of the sliding plate 86, when the operator on the side of the machine sees the movement signal, the electric push rod 806 can be turned off through the device to avoid damage to the electric push rod 806. After the pressing force is adjusted, the motor 4 on the surface of the wire pay-off plate 2 is started, and the output shaft of the motor 4 drives the wire pay-off wheel 3 to rotate to pay off the braided wire. When it is necessary to press a new braided wire of different materials, the electric push rod 806 is driven to drive the support plate 84 downward, and then the fixing ring 82 can abut against the limiting rod 87 to be folded under the support of the torsion spring 89, thereby releasing the pressing of the braided wire.

[0026] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
