Description

Technical Field

[0001] This invention relates to the field of cable wrapping manufacturing technology, and in particular to a four-layer cable wrapping machine. Background Technology

[0002] In the manufacturing process of medium and high voltage cables, a wrapping machine is required to wrap the insulation material around the cable core. Due to the special operating conditions of medium and high voltage cables, the safety requirements of the cables are high. Therefore, the wrapping of the insulation material is an important step in cable production. Existing cable wrapping machines can mostly wrap only 1 to 2 wrapping tapes at a time, and it is difficult to adjust the overlap rate. The overlap rate is used to characterize the ability of the wrapping tape to cover the surface of the cable core with each wrap. The wrapping tape is spirally wound along the axial direction. When wrapping two wrapping tapes, two wrapping tape reels need to be rewound successively. When the required number of wrapping tapes exceeds two, it is necessary to add a wrapping machine or use the same wrapping machine for rewinding. Adding a wrapping machine will increase the work area and production costs, while using the same wrapping machine for rewinding will increase production time and reduce wrapping efficiency. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the technical difficulties of existing cable wrapping machines, such as large size, limited number of wrapping tapes per wrapping, and low wrapping efficiency, and to provide a four-tape cable wrapping machine that has more wrapping layers and integrates them into the same wrapping machine, thereby reducing the floor space occupied.

[0004] To solve the above-mentioned technical problems, the present invention provides a four-layer cable wrapping machine, which has a cable core inserted inside and includes a wrapping device, wherein the wrapping device includes,

[0005] A pair of turntables are arranged opposite each other and can rotate coaxially around the cable core. Both ends of the turntables are equipped with wrapping reels for outputting wrapping tape.

[0006] The guide groove is spirally arranged and winds around the cable core; its guide opening is connected to the outlet end of the wrapping reel, and the outlet of the guide groove is inclined towards the front end of the moving direction of the cable core.

[0007] A sliding rod supports the guide strip groove, and its extension direction is parallel to the movement direction of the cable core. One end of the sliding rod is fixed on the turntable, and its free end is provided with a pair of sliders that can slide along its extension direction. The pair of sliders are respectively located on both sides of the width direction of the guide strip groove. The sliders adjust the position of the guide strip groove, adjust the strip delivery angle, and limit the guide strip groove by sliding.

[0008] In one embodiment of the present invention, the guide strip groove includes a plurality of connecting block units, and the two sides of the connecting block units are connected by connecting rods.

[0009] In one embodiment of the present invention, a first guide groove is provided on one side of the cable core outlet end, and a second guide groove is provided on one side of the cable core inlet end; the guide grooves connected to the wrapping discs provided on the same side of the turntable have opposite tape output directions.

[0010] In one embodiment of the present invention, the first guide strip grooves are all spirally wound around the cable core at a rate of 90° to 180°, and the second guide strip grooves are all spirally wound around the cable core at a rate of 270° to 360°.

[0011] In one embodiment of the present invention, the slide bar includes a first slide bar, a second slide bar, and a third slide bar; the first slide bar is supported on the inner side of the first guide strip groove winding path, and the second slide bar and the third slide bar are sequentially supported on the inner side of the second guide strip groove winding path.

[0012] In one embodiment of the present invention, the free end of the third slide rod supports one end of the tape outlet of the second guide groove, and the length of the second slide rod is less than that of the third slide rod.

[0013] In one embodiment of the present invention, the center of the tape reel is fixed to the turntable by a mounting shaft, and a guide groove fixing block is provided at the connection between the tape reel and the guide groove.

[0014] In one embodiment of the present invention, the wrapping device further includes a rotating shaft mounting block, the two ends of which are coaxially connected to the turntable, and the rotating shaft mounting block is hollow inside and has a cable guide tube for the cable core to pass through.

[0015] In one embodiment of the present invention, it further includes a driving device, the driving device including a drive motor, the drive motor driving the drive wheel to rotate via a transmission shaft, the drive wheel and the driven wheel being driven by a transmission belt, and the driven wheel being connected by a bearing and driving the rotating shaft mounting block to rotate.

[0016] In one embodiment of the invention, it further includes a frame, the frame including mutually perpendicular support bases and columns, and support beams at both ends respectively connecting the support bases and the columns.

[0017] The technical solution of the present invention has the following advantages compared with the prior art:

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0027] Example

[0028] Reference Figure 1As shown, the present invention provides a four-tape cable wrapping machine, which has a cable core 52 inserted inside. The four-tape cable wrapping machine includes a wrapping device, a drive device and a frame 6. The wrapping device is located at the top of the frame 6. The wrapping device includes a pair of turntables, a wrapping tape reel, a rotating shaft mounting block 51, a guide tape groove and a slide bar.

[0029] Specifically, refer to Figure 1 As shown, a pair of turntables are arranged opposite each other and can rotate coaxially around the cable core 52; the two ends of the rotating shaft mounting block 51 are respectively coaxially connected to the turntables, the interior of the rotating shaft mounting block 51 is hollow and a cable inlet tube 53 is provided for the cable core 52 to pass through; wrapping reels are installed on the outer side of the turntables for outputting wrapping tape; the guide groove is spirally wound around the cable core 52; its guide opening is connected to the outlet end of the wrapping reel, and its tape outlet is located on the outer layer of the cable core 52.

[0030] Furthermore, refer to Figure 1 , Figure 2 and Figure 3 As shown, along the moving direction of the cable core 52, the turntable on one side of the cable core 52's output end is configured as a first turntable 1. The first turntable 1 has a first wrapping reel 11 and a second wrapping reel 13 installed at both ends for outputting the wrapping tape. A first guide groove is also provided on one side of the cable core 52's output end. The first guide groove includes a first guide groove A12 and a first guide groove B14. The guide opening of the first guide groove A12 connects to the output end of the first wrapping reel 11, and the guide opening of the first guide groove B14 connects to the output opening of the second wrapping reel 13. The first guide grooves connected to the two wrapping reels on the same side output tape in opposite directions. Both the first guide groove A12 and the first guide groove B14 rotate around the cable core 52 by 90° to 180°. Specifically, refer to... Figure 1 As shown, along the moving direction of the cable core 52, the turntable on one side of the cable core 52's inlet end is configured as a second turntable 2. The two ends of the second turntable 2 are equipped with a third wrapping reel 21 and a fourth wrapping reel 23 for outputting wrapping tape. A second guide groove is also provided on one side of the cable core 52's inlet end. The second guide groove includes a second guide groove A22 and a second guide groove B24. The guide opening of the second guide groove A22 is connected to the outlet end of the third wrapping reel 21, and the guide opening of the second guide groove B24 is connected to the outlet of the fourth wrapping reel 23. The second guide grooves connected to the two wrapping reels on the same side output tape in opposite directions. The second guide groove A22 and the second guide groove B24 are both wound and rotated around the cable core 52 as an axis for 270° to 360°. Since the first guide groove and the second guide groove are respectively provided on both sides of the turntable, their spiral winding angle can make the end of the guide groove close to the surface of the cable core 52, and can also adapt to the bending performance of the guide groove material.

[0031] Furthermore, the two tape reels on the same side are connected to guide grooves with opposite tape output directions, but the spiral winding directions and wrapping directions are the same; refer to Figure 2 As shown, in this embodiment of the invention, the guide tape opening and exit tape opening of the first guide tape groove A12 are located on opposite sides of the cable core 52, and the guide tape opening and exit tape opening of the first guide tape groove B14 are also located on opposite sides of the cable core 52, but opposite to the first guide tape groove A12; when the first guide tape groove A12 and the first guide tape groove B14 have the same length and the same winding angle but are wound on opposite sides, the guide tape paths of the guide tape grooves provided on the same side of the turntable do not cross, and there is no overlapping contact part. Different wrapping tape reels do not interfere with each other when wrapping tape, reducing tape wear and equipment failure rate. (Refer to...) Figure 3 As shown, the second guide strip groove A22 and the second guide strip groove B24 are also non-contact parts that are wound on opposite sides.

[0032] Furthermore, refer to Figure 1 , Figure 2 and Figure 3 As shown, the guide groove connects the wrapping reel and the cable core 52, supporting the wrapping tape used for wrapping. In this embodiment of the invention, the guide groove includes several connecting block units. The two sides of the connecting block units are connected by connecting rods. On the one hand, the free end of the guide groove can be adjusted to make the tape outlet of the guide groove tilted towards the front end of the moving direction of the cable core 52, and facilitates the adjustment of the bending and spiral winding angle of the guide groove, thereby adjusting the overlap rate of the wrapping tape on the surface of the cable core 52. On the other hand, the connecting block units have a certain mechanical strength, which can support and protect the wrapping tape, prevent slippage and damage during the conveying of the wrapping tape, and reduce the situation of cracks or tape breakage caused by excessive tension when tightening the wrapping tape.

[0033] Specifically, the wrapping device also includes a slide bar, as shown in the reference. Figure 1 , Figure 2 and Figure 3 As shown, the sliding rod supports the guide groove, and its extension direction is parallel to the movement direction of the cable core 52. One end of the sliding rod is fixed on the turntable, and its free end is provided with a pair of sliders 4 that can slide along its extension direction. The pair of sliders 4 are respectively located on both sides of the width direction of the guide groove. The sliders 4 drive the guide groove to move horizontally by sliding, which, in conjunction with the adjustment of the tape outlet direction of the guide groove, adjusts the tape outlet angle of the guide groove, increases the tape overlap rate, and limits the guide groove in the width direction to prevent slippage. Since the guide grooves on the same side have tape outlets in opposite directions, it is convenient to set sliding rods supporting the guide grooves on both sides of the radial direction of the rotating shaft mounting block 51.

[0034] Furthermore, refer to Figure 2 and Figure 3As shown, the slide bar includes a first slide bar 31, a second slide bar 32, and a third slide bar 33. The first slide bar 31 is supported on the inner side of the winding path of the first guide strip groove, and the second slide bar 32 and the third slide bar 33 are sequentially supported on the inner side of the winding path of the second guide strip groove. It should be noted that since the second guide strip groove is located on the side of the cable core 52 inlet end, the guide strip opening direction of the second guide strip groove is opposite to the moving direction of the cable core 52, while the outlet of the second guide strip groove is inclined towards the front end of the moving direction of the cable core 52. Therefore, the winding rotation angle of the second guide strip groove is larger than that of the first guide strip groove, and the length of the second guide strip groove is longer than that of the first guide strip groove. In order to ensure the spiral winding angle of the second guide strip groove, in this embodiment of the invention, the second slide bar 32 and the third slide bar 33 are both supported on the inner side of the second guide strip groove, and the free end of the third slide bar 33 is used to support one end of the outlet of the second guide strip groove. Therefore, the length of the second slide bar 32 is smaller than that of the third slide bar 33.

[0035] Furthermore, refer to Figure 4 As shown, the center of the tape reel is fixed to the turntable by a mounting shaft 81. The tape reel includes a tape reel upper seat 83 and a tape reel base 84 arranged coaxially. The tape used for wrapping is wound between the tape reel upper seat 83 and the tape reel base 84, which facilitates the overall replacement of the tape reel core 85. In this embodiment of the invention, the tape reel and the tape reel core 85 are fixed by a fastening bolt 82 at one end of the mounting shaft 81. A guide groove fixing block 41 is provided at the connection between the tape outlet end of the tape reel and the guide groove opening, which is used to fix the guide groove to the tape reel.

[0036] Reference Figure 1 As shown, the four-layer cable wrapping machine also includes a frame 6 and a drive unit. The frame 6 includes mutually perpendicular support bases 62 and columns 61. The two ends of the support base 62 are fixed by bolts 64 to enhance the overall stability of the wrapping machine. The frame 6 also includes support beams 63 that connect the support bases 62 and columns 61 at both ends respectively. When the wrapping machine is wrapping, the upper turntable and the wrapping tape reel have a certain weight and are wrapping while rotating. Therefore, the frame 6 of the wrapping machine needs to have strong support. The support beams 63, support bases 62, and columns 61 form a triangular structure, which provides better stability. Specifically, the drive unit includes a drive motor 71, which is located above the support base 62. It drives the drive wheel 73 to rotate through a transmission shaft 72. The drive wheel 73 and the driven wheel 74 are driven by a transmission belt 75. The driven wheel 74 is connected by a bearing 76 and drives the rotating shaft mounting block 51 to rotate, thereby causing the turntable to rotate and wrap the tape.

[0037] The working principle of the four-layer cable wrapping machine described in this invention is as follows:

[0038] A wrapping reel core 85 is installed between the wrapping reel upper seat 83 and wrapping reel base 84 of the first wrapping reel 11, second wrapping reel 13, third wrapping reel 21, and fourth wrapping reel 23, and is fixed by mounting shaft 81 and fastening bolt 82. The slider 4 is adjusted and limited in the width direction of the guide groove according to the wrapping overlap rate of the cable core 52 and the properties of the wrapping tape material. The drive motor 71 is started, driving the drive wheel 73 to rotate via the transmission shaft 72, and then driving the driven wheel 74 to rotate via the transmission belt 75. The driven wheel 74 is connected by a bearing 76 and drives the rotating shaft mounting block 51 and the turntable to rotate coaxially. The rotation direction of the turntable is consistent with the tape wrapping direction of the guide groove. The first and second guide grooves wrap around the outer layer of the cable core 52 sequentially as the cable core 52 moves. The four-wrap cable wrapping machine of the present invention can wrap four wrapping tapes simultaneously, reducing equipment space occupation and improving production efficiency.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
