[0025] The positioning adjustment component includes a perforated slide rail 5, which is mounted on the top of the turntable 2. A positioning mounting plate 6 is connected to the outer side of the perforated slide rail 5, and a fixing plate 7 is connected to the inner side of the positioning mounting plate 6. A positioning card plate 11 is provided on the inner side of the fixing plate 7. The positioning adjustment component is used to adjust the angle adjustment range of the wire.
[0026] Specifically, such as Figure 3 As shown, a positioning slot 8 is provided at the top of the inside of the fixing plate 7, and a positioning screw is connected to the outside of the fixing plate 7. The positioning plate 11 can be fixedly connected to the positioning slot 8 inside the fixing plate 7 by the positioning screw.
[0027] Specifically, such as Figure 3 As shown, a movable connecting block 9 is connected to the inner side of the fixed plate 7, and an adjusting wheel 19 is connected to the inner side of the movable connecting block 9. A support slide frame 10 is connected to the top of the movable connecting block 9. The movable connecting block 9 slides in the U-shaped groove inside the fixed plate 7, and can be adjusted to a certain position.
[0028] Specifically, such as Figure 3As shown, the positioning plate 11 is slidably connected to the inner side of the support slide frame 10, and the top of the positioning plate 11 is connected to a tension rod 12. A reset connector 13 is provided on the outer side of the tension rod 12. Through the elastic force of the reset connector 13, the positioning plate 11 will be pressed downward inside the support slide frame 10 until the positioning plate 11 is stuck inside the positioning slot 8.
[0029] The buffer connection assembly includes a fixed connection plate 14, which is disposed at the bottom end of the wire threading tube 1. A guide roller 17 is disposed at the bottom end of the fixed connection plate 14, and a buffer connector 18 is disposed on the inner side of the guide roller 17. The buffer connection assembly is used for buffer protection during wire conduction.
[0030] Specifically, such as Figure 4 As shown, a rotating block 15 is connected to the bottom end of the fixed connecting plate 14, and a guide connecting rod 16 is connected to the bottom end of the rotating block 15. The guide connecting rod 16 is rotatably connected to the bottom end of the rotating block 15 to facilitate the elastic stretching of the buffer connecting piece 18.
[0031] Specifically, such as Figure 4 As shown, the guide roller 17 is located inside the guide connecting rod 16, and a screw is provided inside the guide roller 17. The connection of the screw facilitates the removal and replacement of the guide roller 17.
[0032] Specifically, such as Figure 4 As shown, the buffer connector 18 is connected to the inner side of the guide connecting rod 16. The buffer connector 18 is used for the elastic connection of two adjacent guide connecting rods 16, so that the guide clamping rollers 17 on both sides are close to each other and the cable transmission position is flexibly clamped.
[0033] A pre-twist angle adjustment device, wherein the composite cradle cable forming machine is equipped with a pre-twist angle adjustment device as described above.
[0034] In this embodiment: the positioning installation between the perforated slide rail 5 and the positioning mounting plate 6, and the sliding adjustment of the movable connecting block 9 inside the fixed plate 7, with the setting of dual position adjustment, increases the adjustment range. The pre-twist angle can be adjusted for transmission wires of different sizes. When the wire is guided and transmitted into the wire-passing drum 1, it is first flexibly clamped and transmitted by the elasticity of the buffer connector 18 through the adjacent guide roller 17. The entry position of the wire can be limited and protected, improving the accuracy of the wire transmission position.
[0035] The specific solution is as follows: First, when adjusting the pre-twist angle of the wire on the composite cradle-type cable forming machine, adjacent guide rollers 17 are brought closer to the wire, and then the elasticity of the buffer connector 18 is used for flexible clamping and transmission. This limits and protects the wire as it enters the threading drum 1. During the adjustment process, the wire is clamped by the two adjusting wheels 19 at the top. By rotating the connecting block 4, the turntable 2 is rotated, which controls the transmission angle of the wire. When adjustments are needed due to changes in the wire's dimensions during transmission, the moving connecting block 9 is used to... The fixed plate 7 slides in the U-shaped groove on its inner side, allowing for certain position adjustments. Then, through the elastic force of the reset connector 13, the positioning plate 11 is pressed downward inside the support slide frame 10 until the positioning plate 11 is locked inside the positioning slot 8. The positioning plate 11 can then be fixedly connected to the positioning slot 8 inside the fixed plate 7 by the positioning screw, which can position the adjustment position of the adjusting wheel 19. The perforated slide rail 5 at the bottom and the positioning mounting plate 6 can also slide and adjust, further increasing the adjustment range between the adjusting wheels 19 and improving the efficiency of use.
