[0021] The technical solution in the embodiment of the present application is to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0022] Embodiment: Refer to Figure 1 - Figure 3 As shown in the figure, a high-speed concentric wrapping machine in this embodiment includes a frame body 1, and a wrapping component is arranged at the upper end inside the frame body 1;

[0023] The wrapping component includes a pay-off reel 4 and a rotating body 6. The rotating body 6 is movably installed in the middle inside the frame body 1, and the pay-off reel 4 is movably installed in the middle inside the rotating body 6. The pay-off reel 4 is an existing mature technology, which can convey and straighten the cable product to avoid bending and deformation of the cable product during the pay-off process.

[0024] Both the pay-off reel 4 and the rotating body 6 are driven by an AC variable frequency motor 2 to perform rotational motion. The AC variable frequency motor 2 is located in the middle at the bottom end of the rotating body 6 and is fixedly installed at the bottom inside the frame body 1; A turntable 15 is arranged in the middle at the left end of the rotating body 6, and multiple groups of support rods 16 are arranged on the left end surface of the turntable 15. A wrapping head 17 is arranged at the left end of the support rod 16. Multiple groups of wrapping heads 17 are distributed around the outer side of the pay-off reel 4. The bottom of the wrapping head 17 can rotate, which is convenient for the staff to adjust the angle of the wrapping head 17 and then limit and fix it with a fastening bolt.

[0025] Among them, driven by the AC variable frequency motor 2, the pay-off reel 4 and the rotating body 6 can be driven to perform rotational motion at the same time. When the cable product is conveyed from the outlet of the pay-off reel 4, at this time, the wrapping heads 17 around the outer side will perform rotational motion under the rotation of the rotating body 6, so that the wrapping material installed on the wrapping heads 17 wraps the outer surface of the cable product. In addition, the setting of multiple groups of wrapping heads 17 facilitates the staff to perform multi-layer wrapping work on the cable according to needs.

[0026] Take-up component, the take-up component includes a mounting rack 19. The mounting rack 19 is arranged in the middle at the left end of the frame body 1. A take-up reel 21 is movably installed at the upper end inside the mounting rack 19. The take-up reel 21 is driven by a driving motor 20, and the driving motor 20 is fixedly installed at the bottom inside the mounting rack 19.

[0027] The drive motor 20 drives the take-up wheel 21 to rotate, thereby achieving the winding of the wrapped cable product.

[0028] A main synchronous wheel 3 is installed at the output end of the AC variable frequency motor 2, a first sub-synchronous wheel 5 is installed at the middle of the right end of the wire reel 4, and a second sub-synchronous wheel 7 is installed at the middle of the right end of the rotating body 6. The main synchronous wheel 3 and the first sub-synchronous wheel 5 are connected by a first circular arc tooth synchronous belt 8, and the main synchronous wheel 3 and the second sub-synchronous wheel 7 are connected by a second circular arc tooth synchronous belt 9.

[0029] Among them, under the drive of the AC variable frequency motor 2, through the transmission of the first circular arc tooth synchronous belt 8 and the second circular arc tooth synchronous belt 9, the pay-off drum 4 and the rotating body 6 can be driven to rotate at the same time.

[0030] A magnetic powder clutch 14 is fixedly installed on the inner upper end of the frame 1. The magnetic powder clutch 14 is located in the middle of the upper end of the wire reel 4. The right end of the central axis of the magnetic powder clutch 14 is installed with a fourth sub-synchronous wheel 13. The middle of the right end of the wire reel 4 is installed with a third sub-synchronous wheel 11. The third sub-synchronous wheel 11 is located in the middle of the left end of the first sub-synchronous wheel 5. The third sub-synchronous wheel 11 and the fourth sub-synchronous wheel 13 are connected for transmission through a third arc tooth synchronous belt 12.

[0031] When the pay-off drum 4 rotates, the third arc tooth synchronous belt 12 drives the magnetic powder clutch 14 to operate at the same time. The magnetic powder clutch 14 is used to control the winding tension to ensure the quality and consistency of the winding.

[0032] In some examples, a nylon mold sleeve 10 is fixedly installed on the upper right end of the frame 1. The nylon mold sleeve 10 is located in the middle of the right end of the wire reel 4. The cable product passes through the nylon mold sleeve 10 for transportation.

[0033] In some examples, a tape storage rack 18 is further provided between the wrapping assembly and the take-up assembly.

[0034] In some examples, the center lines of the pay-off reel 4 , the nylon mold sleeve 10 , and the tape storage rack 18 are in the same horizontal plane.

[0035] The working principle of this utility model is:

[0036] When the cable product needs to be wrapped, first, the cable product is passed through the nylon mold sleeve 10 into the wire drum 4, and the wire is unwound smoothly. At the same time, the wrapping material is installed on the wrapping head 17, and the angle and tension of the wrapping head 17 can be adjusted by rotating the wrapping head 17, and then it is fixed by tightening the screws. At this time, the staff needs to manually wrap the head end of the wrapping material around the cable product for preliminary wrapping.

[0037] Then, start the AC variable-frequency motor 2. Driven by the AC variable-frequency motor 2, both the wire pay-off reel 4 and the rotating body 6 perform rotational movements. As the cable product is conveyed, when the rotating body 6 drives the turntable 15 to rotate, the wrapping head 17 rotates simultaneously, thereby realizing the winding of the wrapping material on the outer surface of the cable, so as to perform the wrapping work on the cable product.

[0038] In addition, by providing a tape storage rack 18, the wrapped cable can be guided. At the same time, by providing a take-up assembly, the wrapped cable can be wound and stored.
