[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] like Figures 1-4As shown, this invention illustrates an adjustable tension cable stranding machine according to one embodiment of the present invention, comprising: a base plate 1, a drive assembly 2 mounted on the top of the base plate 1, a fixed column 3 fixedly connected to the right end of the drive assembly 2, a rotating assembly 5 mounted on the fixed column 3 near the left side, and a positioning assembly 6 mounted on the top of the rotating assembly 5; a fixed plate 4, rotatably connected to the drive assembly 2, a through groove 8 opened on the left end of the fixed plate 4, a detection assembly 9 installed inside the through groove 8, and through holes 7 opened on the fixed plate 4, with a plurality of through holes 7 corresponding one-to-one with the through groove 8.

[0030] For example, such as Figure 1 As shown, the drive assembly 2 includes a drive motor 21. The drive motor 21 is fixedly connected to the top of the base plate 1. A rotating rod 22 is fixedly installed at the output end of the drive motor 21. A guide frame 24 is fixedly connected to the top of the base plate 1 and to the right of the drive motor 21. The right end of the rotating rod 22 extends into the interior of the guide frame 24 and is fixedly connected to a drive gear 23. A driven gear 25 is rotatably connected inside the guide frame 24. A second guide frame 26 is fixedly connected to the top of the base plate 1 and to the right of the guide frame 24. The interior of the second guide frame 26 is rotatably connected to the fixed plate 4. When the drive motor is started, the rotating rod 22 drives the drive gear 23 to rotate. The drive gear 23 drives the driven gear 24, causing the fixed column 3 and the fixed plate 4 to rotate. By reasonably designing the number of teeth of the double gears, a large transmission ratio is achieved, which can convert the high speed of the input shaft into the low speed of the output shaft.

[0031] For example, such as Figure 4 As shown, the rotating assembly 5 includes a base block 51, which is fixedly connected to the fixed column 3. The top of the base block 51 is also fixed with a support frame 52. The top of the support frame 52 is fixedly connected to a guide rail 53. A rotating plate 54 is rotatably connected to the guide rail 53. A main shaft motor 55 is fixedly connected to the top wall of the inner cavity of the support frame 52. An active shaft 56 is fixedly installed at the output end of the main shaft motor 55. The upper end of the active shaft 56 is fixedly connected to the bottom end of the rotating plate 54. A support rod 57 is fixedly connected to the top of the rotating plate 54. A limit block 58 is fixedly connected to the support rod 57. A connecting rod 59 is fixedly connected to the top of the support rod 57. The main shaft motor 55 drives the active shaft 56 to rotate. The active shaft 56 drives the rotating plate 54 to rotate under the limitation of the guide rail 53. The rotating plate 54 drives the support rod 57 and the limit block 58 to move the raw material. The tension can be adjusted according to the cable type and the cable feeding requirements to ensure that the cable is taut during the feeding process and to avoid slack and knotting.

[0032] For example, such as Figure 4As shown, the positioning component 6 includes a top plate 61, which is threaded onto the connecting rod 59. A slide rod 62 is slidably connected inside the top plate 61. A limit ring 63 is fixedly connected to the bottom of the top plate 61 and outside the slide rod 62. A positioning plate 65 is fixedly connected to the bottom of the slide rod 62. A spring 64 is sleeved on the slide rod 62. There are several rotating components 5, positioning components 6, and detection components 9. The multiple rotating components 5, positioning components 6, and detection components 9 form a circumferential array around the central axis of the fixed column 3. The top plate 61 is installed on the connecting rod 59 by a screw. When the positioning component 6 is installed, the top plate 61 rotates and moves downward. The spring 64 is compressed and pushes the positioning plate 65 downward, which facilitates the determination of the position of the raw material.

[0033] In some examples, before stranding, the raw material is first placed on the support rod 57, and the top plate 61 is installed on the connecting rod 59 by screws. The positioning component 6 is activated. After the positioning component 6 is installed, the top plate 61 rotates and moves downward. The spring 64 is compressed and pushes the positioning plate 65 downward, which facilitates the determination of the raw material's position. At the same time, the spring 64 can further absorb and dissipate energy. When stranding is in progress, the rotating component 5 is activated. The main shaft motor 55 drives the drive shaft 56 to rotate. The drive shaft 56 drives the rotating plate 54 to rotate under the constraint of the guide rail 53. The rotating plate 54 drives the support rod 57 and the limit block 58 to move the raw material. This can be adjusted according to the cable type and laying requirements. The tension is adjusted to ensure the cable remains taut during the feeding process, preventing slack and knots. The main spindle motor 55 is a servo motor equipped with a high-precision encoder, providing accurate feedback on the rotor position for precise position and speed control, facilitating adjustment of the feeding speed. During the wire twisting process, the drive assembly 2 operates. The start-up drive motor drives the rotating rod 22 to rotate the drive gear 23, which in turn drives the driven gear 24, causing the fixed column 3 and fixed plate 4 to rotate. Through a well-designed double gear system, a large transmission ratio is achieved, converting the high speed of the input shaft into a low speed of the output shaft, meeting the needs of low-speed, high-torque equipment and providing the power source for wire twisting.

[0034] like Figures 1-5 As shown, this invention illustrates an adjustable tension cable stranding machine according to another embodiment of the present invention. The detection component 9 includes a fixing member 91. The fixing member 91 is fixedly installed inside the through groove 8 by a screw. The left end of the fixing member 91 is fixedly connected to a fixing box 92. The bottom wall of the inner cavity of the fixing box 92 is fixedly connected to a cylinder 93. The output end of the cylinder 93 is fixedly connected to a support plate 94. The top end of the support plate 94 is fixedly connected to a fixing frame 95. The fixing frame 95 is rotatably connected to a detection roller 96 through a fixing rod. The raw material is fed to the rear through the through groove 8. At the same time, the detection component 9 works. The cylinder 93 is activated to drive the support plate 94, causing the fixing frame 95 to move. The fixing frame 95 drives the detection roller 96 to contact the raw material. According to the system calculation, the feeding speed of the rotating component 5 and the position of the detection roller 96 are further controlled to prevent the tension from being too high or too low.

[0035] In some examples, during the twisting process, the rotating assembly 5 feeds the material, which is then conveyed to the rear through the through groove 8. Simultaneously, the detection assembly 9 operates, and the starting cylinder 93 drives the support plate 94 to move the fixed frame 95. The fixed frame 95 then drives the detection roller 96 to contact the material. A tension sensor is mounted on the fixed rod to facilitate the detection of the pressure on the detection roller 96. Based on the system calculations, the feeding speed of the rotating assembly 5 and the position of the detection roller 96 are further controlled to prevent excessive or insufficient tension and ensure the normal operation of production.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
