[0023] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0024] Reference Figures 1 to 3 As shown, a device for preventing strand jumping of the hinge wire of a frame stranding machine is provided, including a base 1, which is fixedly mounted on the strand center tube 5 of the frame stranding machine. A first through hole 12 for preventing the hinge wire from jumping is provided in the middle of the base 1, a column 2 is provided in the middle of the base 1, a second through hole 21 is provided in the column 2, the first through hole 12 is communicated with the second through hole 21, a fixing hole 22 is provided on the column 2, a set screw 3 is detachably mounted on the fixing hole 22, and the hinge wire passes through the first through hole 12 and the second through hole 21 in sequence.

[0025] In this embodiment, the stranded wire passes through the stranded wire center tube 5, and then passes through the first through hole 12 and the second through hole 21 in sequence to prevent the stranded wire from jumping during operation and limit its range of movement. The base 1 is fixedly installed on the stranded wire center tube 5, and the connection between the base 1 and the stranded wire center tube 5 is reinforced by the hexagon socket screw 4 so that the base 1 itself does not vibrate when the stranded wire swings. A fixing hole 22 is opened on the column 2, and a set screw 3 is detachably installed on the fixing hole 22 to make the column 2 more stable and not easily damaged when the stranded wire swings.

[0026] Furthermore, mounting holes 11 are provided on both sides of the base 1, and the mounting holes 11 are fixedly connected to the stranded wire center tube 5 through hexagon socket screws 4, so that the base 1 is fixed on the stranded wire center tube 5 to prevent the base 1 from loosening and falling when the stranded wire swings.

[0027] In one embodiment of the present invention, the diameter of the first through hole 12 is smaller than the diameter of the second through hole 21. The stranded wire first passes through the first through hole 12 to limit its range of movement. The second through hole 21 is provided to prevent the stranded wire from swinging too much. The diameter of the second through hole 21 is larger than the diameter of the first through hole 12. When the stranded wire passes through and swings, the contact between the stranded wire and the second through hole 21 is reduced, thereby reducing wear on the stranded wire.

[0028] The diameters of the first through hole 12 and the second through hole 21 cannot be too large or too small, and sufficient space must be left for the twisted wire to pass through and move. At the same time, the twisted wire cannot swing too much. Preferably, the diameter of the first through hole 12 is 15mm~16mm, and the diameter of the second through hole 21 is 24mm~25mm.

[0029] In one embodiment of the present invention, the fixing hole 22 is perpendicular to the second through hole 21 , so that the set screw 3 is also perpendicular to the second through hole 21 . The set screw 3 fixes the column 2 so that the column 2 is not affected and swings, thereby increasing the service life of the column 2 .

[0030] In one embodiment of the present invention, the column 2 is welded to the middle of the base 1 .

[0031] Preferably, if the column 2 is too long, the stranded wire will be damaged by friction with the column 2, and if the column 2 is too short, the swing of the stranded wire cannot be restricted. Therefore, the length of the column 2 is 17mm~17.5mm. In order not to affect the other outlets of the stranded wire center tube 5 for passing the stranded wire out, the length of the base 1 is 140mm~142mm.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
