Detailed ways

In order to further understand the inventive content, features and effects of the present invention, the following examples are hereby described in detail.

1 and 2, the braiding device for a high-speed braiding machine of the present invention includes a base plate 1, on which is mounted a first turntable 4 with three first notches 4-1 on the outer edge through a shaft seat and a second turntable 5 with three second notches 5-1 on the outer edge, a drive motor 2 is also installed on the base plate 1, and a first driven gear coaxial with the first turntable 4 is installed below the base plate 1 7 and the second driven gear 6 coaxial with the second turntable 5, the two are engaged for transmission, and the driving gear 9 installed on the motor shaft of the driving motor 2 drives one of the driven gears to rotate. Under the driving action of the driving motor 2, the first turntable 4 and the second turntable 5 both rotate synchronously, at high speed and in opposite directions.

In this embodiment, a transmission gear 8 that meshes with the first driven gear 7 or the second driven gear 6 is also installed below the base plate 1 , and the driving gear 9 meshes with the transmission gear 8 for transmission.

Three winding assemblies 3 are installed between the corresponding notches of the two turntables. Under the combined action of the first turntable 4 and the second turntable 5, the three winding assemblies 3 each follow a "8"-shaped path. Move to create a braided motion and braided effect similar to a "twist braid".

Referring to Figure 3, it can be seen that the winding assembly 3 includes an "I"-shaped ingot seat 3-3 with a slider 3-2 at the bottom, and a let block 3-1 is installed in the middle of the ingot seat 3-3, allowing The block 3-1 falls into the corresponding slot (let the block 3-1 be clamped between a set of corresponding first slots 4-1 and the second slot 5-1), correspondingly, on the surface of the substrate 1 , The bottom of the first turntable 4 and the second turntable 5 are respectively provided with a circular first slideway and a second slideway, and the first slideway and the second slideway are connected in the middle to form a complete "8" shape. Slide way, each slider 3-2 is located in the slide way.

Therefore, under the driving action of both the first turntable 4 and the second turntable 5, when the three winding assemblies 3 move along the above-mentioned through "8"-shaped slideway, the slider 3-2 moves between the first slideway and the When the penetrating position between the second slideways is moved, one slideway can enter the other slideway (correspondingly, the let block 3-1 of each winding assembly 3 is transferred from the notch of the previous turntable to the notch of the latter turntable). notches), so each winding assembly 3 also moves on an "8"-shaped path, and the three winding assemblies 3 together form a "twist braid" braiding action.

A base 3-4 is installed on the spindle base 3-3 (fixed by fixing screws); 10 is loaded on the bobbin central axis 3-12. Specifically, the base 3-4 is provided with a rotating shaft, and a bearing is installed between the rotating shaft and the bobbin seat 3-5, so the bobbin central axis 3-12 (and the yarn bobbin 10) is connected to the bobbin seat 3-5.
