[0031] A multi-strand wire stranding device, such as Figures 1-3As shown, the device includes a wire stranding machine housing 10 for cable production. A door 20 is installed on one side of the housing 10. Several evenly spaced, linearly arranged stranding shafts 30 for mounting stranding reels 50 are installed on the top of the housing 10. A servo geared motor 40 is installed inside the housing 10. Several sets of driven shafts 12 coaxially connected to the stranding shafts 30 are installed inside the housing 10. The driven shafts 12 are connected to the upper and lower sides of the housing 10 via bearings 14. Each set of driven shafts 12 is connected to two sets of parallel transmission sprockets 13. Adjacent sets of driven shafts 12 are connected to the transmission sprockets 13 via a transmission chain 60. The drive shaft 41 of the servo geared motor 40 is coaxially connected to one set of stranding shafts 30. A drive sprocket 42 is installed on the drive shaft 41, and the drive sprocket 42 is connected to the adjacent transmission sprocket 13 via a transmission chain 60. The wire stranding machine housing 10 has a door 20 for easy maintenance and operation of the interior. The top of the housing has evenly spaced, linearly arranged stranding shafts 30 for mounting stranding discs 50, facilitating the stranding of multiple wires. A servo geared motor 40 is installed inside the housing; its drive shaft 41 is coaxially connected to a set of stranding shafts 30, and is connected to adjacent drive sprockets 13 via a drive chain 60 through a drive sprocket 42, thus transmitting power. Simultaneously, several sets of driven shafts 12 are installed inside the housing, coaxially connected to the stranding shafts 30. These driven shafts 12 are connected to the upper and lower sides of the housing via bearings 14. Each set of driven shafts 12 has two parallel drive sprockets 13 connected to it, and adjacent sets of driven shafts 12 are connected to each other via a drive chain 60, allowing multiple stranding shafts 30 to rotate synchronously, thereby achieving uniform stranding of multiple wires.

[0032] Furthermore, an anti-collision shell 11 is installed on the outer wall of the wire stranding machine box 10. The anti-collision shell 11 effectively protects the wire stranding machine box 10 from external impacts, preventing damage to the box or loosening of internal parts, and improving the durability and safety of the equipment.

[0033] The wire stranding machine box 10 has fixed bases 15 symmetrically installed at both ends of its bottom. The fixed bases 15 ensure that the wire stranding machine box 10 can be placed stably on the ground, preventing shaking or displacement during use and ensuring the stability of the equipment and the accuracy of operation.

[0034] Specifically, the bottom of the door 20 is connected to the wire stranding machine box 10 via a hinge 21. A door lock strip 23 is installed at the top center of the side of the wire stranding machine box 10 near the door 20. The door lock strip 23 is rotatably connected to the outer wall of the wire stranding machine box 10 via a pivot 24. Through the hinge 21 and the door lock strip 23, the door 20 can be opened and closed easily, and the door lock strip 23 can securely lock the door.

[0035] It is worth noting that a groove 22 is installed in the middle of the outer wall of the box door 20, which makes it easier for operators to grab and pull open the box door 20, improving the convenience and efficiency of operation.

[0036] Furthermore, the stranding shaft 30 is connected to the drive shaft 41 and the driven shaft 12 via a rotating rod 31. A limiting disc 32 is coaxially connected to the bottom of the outer wall of the stranding shaft 30. Through the rotating rod 31 and the limiting disc 32, the stranding shaft 30 can be firmly connected to the drive shaft 41 and the driven shaft 12, and maintain a stable position during rotation, preventing the stranding shaft 30 from shaking or falling off, and ensuring the stability and reliability of the stranding process. At the same time, the limiting disc 32 also serves as a limit, preventing the stranding disc 50 from slipping or shifting during the stranding process.

[0037] Working principle of this multi-strand wire stranding equipment:

[0038] First, the operator installs the prepared strand spool 50 onto the stranding shaft 30. The stranding shaft 30 is connected to the drive shaft 41 and the driven shaft 12 via a rotating rod 31, ensuring stable rotation of the stranding shaft 30. At the same time, the limiting plate 32 at the bottom of the stranding shaft 30 can prevent the strand spool 50 from slipping or shifting during the stranding process.

[0039] Then, the operator starts the servo geared motor 40. The drive shaft 41 of the servo geared motor 40 transmits power to the drive sprocket 13 on the driven shaft 12 connected to the stranded wire shaft 30 through the drive sprocket 42 and the drive chain 60. In this way, multiple stranded wire shafts 30 can rotate synchronously to achieve uniform stranding of multiple wires.

[0040] During the stranding process, the operator can ensure smooth stranding by observing the inside of the chassis and monitoring the operating status of the equipment. Once stranding is complete, the operator can turn off the servo geared motor 40 and reopen the chassis door 20 to remove the stranded wire.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
