TECHNICAL FIELD

[0001] The utility model relates to water -resistant conductor production technical field, especially in water -resistant yarn winding device. BACKGROUND

[0002] The existing water -resistant conductor adopts longitudinal water -resistant tape to carry out water -resistant, when producing, water -resistant tape tension is flat to water -resistant yarn winding machine, and the water -resistant yarn is wound to water -resistant tape in winding machine to make water -resistant tape completely wraps conductor, and after wrapping, enters conductor stranding mould, and after copper wire stranding, finally fills water -resistant tape to conductor gap.

[0003] In the production process, water -resistant tape wraps conductor mainly through water -resistant yarn winding, but because water -resistant tape belongs to flat state at this time, in the rotating process of winding machine, because water -resistant tape does not closely adhere to conductor, water -resistant yarn can drive water -resistant tape and conductor, mould friction in the winding process and thus wrinkle, or extrude water -resistant tape to make water -resistant tape unable to completely cover, and thus part of water -resistant tape concentrates in one place, and the surrounding appears empty, leads to water -resistant tape incomplete wrapping, influences water -resistant performance of water -resistant conductor.

[0006] The rotating disc is provided with a first through hole in the center;

[0007] The mould is provided with a second through hole in the center, and the inner diameter of the second through hole gradually decreases from one end to the other end;

[0008] The mould sleeve is sleeved on the outer periphery of the mould, the mould sleeve and the mould can relatively rotate coaxially, and the mould sleeve is fixed to the center of the rotating disc through a plurality of connecting rods.

[0009] The water -resistant yarn winding device has the beneficial effects that when the water -resistant yarn winding device is used, the water -resistant tape pre-wraps the conductor from the end of the second through hole with a larger inner diameter into the mould, and as the hole diameter becomes smaller and smaller, the two ends of the tape gradually coincide and approach, finally overlap and closely adhere to the conductor as much as possible, and after overlapping, the tape is taken out of the mould from the other end of the second through hole, and is fixed by the water -resistant yarn winding, so that the tape completely wraps the conductor, thereby effectively reducing or even avoiding the tape from wrinkling and folding in the water -resistant yarn winding process, and ensuring the water -resistant performance of the water -resistant conductor.

Water-blocking yarn is pre-wound on the winding post. During use, the turntable drives the water-blocking yarn to rotate around the conductor, causing the water-blocking yarn to wrap around the water-blocking tape, so that the water-blocking tape completely wraps the conductor.

[0012] In one embodiment of this application, multiple winding posts are provided, and the multiple winding posts are arranged at intervals around the center line of the second through hole. Multiple water-blocking yarns can be wound simultaneously.

[0013] In one embodiment of this application, a bearing is provided between the mold and the mold sleeve. If the mold rotates, it may cause friction between the water-blocking tape and the conductor, resulting in wrinkles in the water-blocking tape and affecting the effect of the water-blocking tape covering the conductor. Therefore, when the mold sleeve rotates with the turntable, the bearing is used to minimize or avoid the rotation of the mold as much as possible to ensure the covering effect of the water-blocking tape.

[0016] In one embodiment of this application, the water-blocking yarn wrapping device further includes a limiting member disposed between the mold sleeve and the turntable, and the limiting member is fixed to the turntable. The space between the limiting member and the mold sleeve defines the limited movement range of the water-blocking yarn.

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0018] 1. This water-blocking yarn wrapping device, through the design of the mold aperture from large to small and the relative rotation design of the bearing, causes the wrapping tape to fully wrap the conductor in advance and reduces the friction between the wrapping tape, the conductor and the mold.

[0030] This application provides a water-blocking yarn wrapping device, which solves the problem of water-blocking tape wrinkling easily when water-blocking yarn is wrapped in the prior art. It effectively reduces or even avoids wrinkling and folding of water-blocking tape during longitudinal wrapping, ensuring the water-blocking performance of the water-blocking conductor.

[0031] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0032] Example:

[0033] like Figs. 1-3 As shown, a water-blocking yarn wrapping device is used in a water-blocking yarn wrapping machine, comprising: a turntable 1, a mold 2, a mold sleeve 3, a bearing 4, and a retaining spring 5.

[0034] The turntable 1 has a first through hole 11 at its center, and the turntable 1 is driven to rotate by the wrapping machine;

[0035] The mold 2 has a second through hole 21 at its center, and the inner diameter of the second through hole 21 gradually decreases from one end to the other.

[0036] The mold sleeve 3 is fitted around the outer periphery of the mold 2. A bearing 4 is provided between the mold 2 and the mold sleeve 3. The mold sleeve 3 and the mold 2 can rotate coaxially relative to each other. The mold sleeve 3 is connected to the turntable 1 through several connecting rods 31. In use, the mold sleeve 3 rotates together with the turntable 1, while the mold 2 has less friction relative to the water-blocking wrapping tape 8.

[0037] The inner edge of the mold sleeve 3 and the outer edge of the mold 2 are respectively provided with a bearing mounting groove 32 and a snap ring mounting groove 33. The snap ring mounting groove 33 is located on the side of the bearing mounting groove 32. The bearing 4 and the snap ring 5 are respectively installed in the bearing mounting groove 32 and the snap ring mounting groove 33. The snap ring 5 is installed on both sides of the bearing 4, and the bearing 4 and the mold 2 are secured by the snap ring 5.

[0038] Furthermore, the turntable 1 is provided with multiple winding posts 12, the center line of which is parallel to the center line of the second through hole 21. The multiple winding posts 12 are arranged at intervals around the center line of the second through hole 21. Water-blocking yarn 9 is pre-wound on the winding posts 12. During use, the turntable 1 drives the water-blocking yarn 9 to rotate around the conductor 7, so that the water-blocking yarn 9 wraps around the water-blocking tape 8, and the water-blocking tape 8 completely wraps the conductor 7. Multiple winding posts can perform multiple water-blocking yarn windings simultaneously.

[0039] Furthermore, the water-blocking conductor 7 wrapping device also includes a limiting member 6, which is disposed between the mold sleeve 3 and the turntable 1 and is fixed to the turntable 1. The space between the limiting member 6 and the mold sleeve 3 defines the limited movement range of the water-blocking yarn 9.

[0040] Optionally, the connecting rod 31 can be a bolt for easy installation and disassembly.

[0041] The process of using the water-blocking conductor 7 wrapping device is as follows:

[0042] Fix the bearing 4 and the retaining ring 5 to the mold sleeve 3, and then fix the mold sleeve 3 to the turntable 1 with bolts (connecting rod 31). After completion, start the machine to pass the conductor 7 through the mold sleeve 3. After passing through the mold sleeve 3, install the half mold 2 with a suitable aperture size, and drag the water-blocking wrapping tape 8 into the mold 2. Fix it with tape and straighten the wrapping tape 8 to ensure that the two ends of the wrapping tape 8 overlap and adhere to the conductor at the exit of the mold 2. Then, open the water-blocking yarn 9 wrapping machine control to start normal production.

[0043] During normal production, the conductor 7, covered with water-blocking tape 8, passes through the second through hole 21 at the end with the larger inner diameter, and then passes through the first through hole 11 after being wrapped by water-blocking yarn 9, and enters the conductor stranding mold for the next production process.

[0044] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0045] 1. This water-blocking yarn wrapping device, through the design of the mold aperture from large to small and the relative rotation design of the bearing, enables the wrapping tape to fully wrap the conductor in advance, and reduces the friction between the wrapping tape and the conductor and the mold, as well as the squeezing of the water-blocking yarn on the water-blocking wrapping tape when it is wrapped. This effectively prevents the water-blocking wrapping tape from wrinkling and folding during the use of water-blocking yarn wrapping, and ensures the water-blocking performance of the water-blocking conductor throughout the entire production process.

[0046] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
