Description

Technical Field

[0001] This utility model belongs to the technical field of cable processing equipment, specifically a guide frame assembly for a cable shielding tape winding machine. Background Technology

[0002] In the cable manufacturing industry, cable shielding tape winding machines are key pieces of equipment used to evenly wrap shielding tape around the outer layer of cables to improve their electromagnetic shielding performance and mechanical strength. In actual production, cables enter and exit the machine through its inlet and outlet pipes, which typically have fixed dimensions. However, due to the diverse diameters of cables, excessive friction when passing through these fixed-size pipes can easily lead to surface damage or uneven shielding tape winding. To address this issue, existing technologies typically employ changing different sized sleeves to accommodate cables of varying thicknesses. However, this method is cumbersome, inefficient, and lacks the flexibility to adapt to real-time cable changes. Furthermore, fixed guide structures lack effective adjustment capabilities when faced with cable eccentricity or positional deviations, further impacting production efficiency and product quality. Therefore, there is an urgent need for a guide device that can flexibly adjust to accommodate various cable specifications and reduce friction, thereby resolving the problems in existing technologies and improving the overall performance of cable shielding tape winding machines. Utility Model Content

[0003] This utility model provides a guide frame assembly for a cable shielding tape winding machine, comprising a support assembly, a cable support shaft, and a support shaft adjustment assembly. The support assembly is located at the inlet and outlet of the cable shielding tape winding machine and is connected to the inlet and outlet conduits of the machine. The support assembly has a through hole in its center, and one end is detachably fixed to the inlet and outlet conduits. The cable support shaft is mounted on both sides of the through hole of the support assembly via the support shaft adjustment assembly, and is arranged in a ring. Through this structural design, the guide frame assembly can flexibly adjust the position of the cable support shaft according to the thickness of the cable to meet the needs of cables of different sizes.

[0004] Furthermore, the support assembly comprises a guide frame base plate, guide frame support columns, a guide frame connecting flange, and connecting flange fixing bolts. The guide frame base plate is the core component of the support assembly, featuring a through hole in its center and multiple guide frame support columns connecting its edges to the guide frame connecting flange. The guide frame connecting flange is annular and is fixedly connected to the inlet and outlet conduits of the shielding tape winding machine using connecting flange fixing bolts. Multiple cable support shafts are mounted on both sides of the through hole in the guide frame base plate via multiple sets of support shaft adjustment assemblies. This modular design ensures a more stable connection between components while facilitating assembly and maintenance.

[0005] Specifically, four cable support shafts are provided, each positioned on either side of the through-hole in the guide frame base plate via four sets of support shaft adjustment assemblies. Two cable support shafts are vertically positioned on one side of the guide frame base plate, located on either side of the through-hole; the other two are horizontally positioned on the other side, above and below the through-hole. The four cable support shafts form a grid-like structure, and the size and position of the holes are adjusted via the support shaft adjustment assemblies to accommodate cables of different thicknesses. Each cable support shaft is rotatably connected to the main shaft via bearings, and one end of the main shaft is fixedly connected to a cable support shaft moving block. This design not only reduces friction during cable insertion and removal but also extends the service life of the equipment.

[0006] Furthermore, the support shaft adjustment assembly includes a guide rail bracket, a cable support shaft moving block, an adjusting screw bracket, a sliding guide rod for the moving block, and a moving block adjusting screw. The guide rail bracket is fixedly connected to the edge of the guide frame base plate, and the adjusting screw bracket is fixedly connected to the middle edge of the guide frame base plate. There are two sliding guide rods for the moving block, with both ends fixedly connected to the guide rail bracket and the adjusting screw bracket respectively, passing through the cable support shaft moving block and slidably connected to it. The two ends of the moving block adjusting screw are rotatably connected to the guide rail bracket and the adjusting screw bracket, and the middle section is threadedly connected to the cable support shaft moving block. When the moving block adjusting screw is rotated, the cable support shaft moving block slides along the sliding guide rods, thereby adjusting the position of the cable support shaft. This combination of threaded adjustment and sliding connection simplifies the adjustment process of the cable support shaft position and improves operational efficiency.

[0007] Furthermore, the adjustment process of the cable support shaft specifically includes the following steps: S1, determine the thickness of the cable and calculate the size and position of the holes in the "well" shaped structure to be adjusted; S2, rotate the adjusting screw of the moving block to make the moving block of the cable support shaft slide along the sliding rod of the moving block; S3, confirm whether the position of the cable support shaft meets the requirements by observation or measurement; S4, repeat the above steps until the position of all cable support shafts is adjusted to the correct position. Through the above steps, the guide frame assembly can accurately adjust the position of the cable support shaft, ensuring smooth and unobstructed cable insertion and exit.

[0008] Specifically, the guide rail bracket and the adjusting screw bracket are fixedly connected by bolts or welding to ensure stability during use. The surface of the sliding rod of the moving block is polished to reduce friction with the moving block of the cable support shaft. The thread of the adjusting screw of the moving block adopts a trapezoidal thread design to improve stability and accuracy during adjustment. These detailed design features further enhance the reliability and durability of the guide frame assembly.

[0009] Furthermore, the guide frame base plate has multiple mounting holes on both sides of the through hole for fixing the guide rail bracket and the adjusting screw bracket. The diameter and spacing of the mounting holes are designed according to actual needs to meet the installation requirements of different equipment models. A sealing ring is provided on the inner side of the guide frame connecting flange to prevent dust and impurities from entering the guide frame assembly. This sealing design improves the protective performance of the guide frame assembly and extends its service life.

[0010] The beneficial effects of this utility model are:

[0011] First, the position of the cable support shaft is adjusted via the support shaft adjustment assembly. This guide frame assembly can accommodate cables of varying thicknesses, eliminating the need for frequent sleeve replacements and significantly improving the equipment's adaptability. Second, the combination of threaded adjustment and sliding connection simplifies the adjustment process of the cable support shaft, improving operational efficiency. Third, the cable support shaft is rotatably connected to the main shaft via bearings, reducing friction during cable insertion and removal and extending the equipment's lifespan. Finally, the bracket assembly employs a modular design, with components connected via detachable fixing methods, facilitating assembly and maintenance and further enhancing the equipment's practicality.

[0012] In summary, this utility model, through structural optimization design of the guide frame assembly, solves the problems of poor adaptability, troublesome sleeve replacement, and high friction in the prior art, providing reliable technical support for the efficient operation of cable shielding tape winding machines.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] like Figure 1 and Figure 2 As shown, the guide frame assembly of this utility model mainly includes a support assembly, a cable support shaft 7, and a support shaft adjustment assembly. The support assembly is the core part of the entire guide frame assembly, and it includes a guide frame base plate 1, guide frame support columns 9, a guide frame connecting flange 10, and connecting flange fixing bolts 11. The guide frame base plate 1 has a rectangular plate structure with a through hole in the middle for accommodating cables. The edge of the guide frame base plate 1 is fixedly connected to the guide frame connecting flange 10 through multiple guide frame support columns 9. The guide frame connecting flange 10 has an annular structure with a sealing ring on its inner side to prevent dust and impurities from entering the interior of the guide frame assembly, thereby improving the protective performance. The guide frame connecting flange 10 is detachably fixedly connected to the edge of the shielding tape winding machine inlet / outlet conduit 12 through the connecting flange fixing bolts 11. This connection method not only facilitates assembly and maintenance but also ensures a stable connection between the guide frame assembly and the shielding tape winding machine inlet / outlet conduit 12.

[0020] Multiple cable support shafts 7 are mounted on both sides of the through hole of the bracket assembly via multiple sets of support shaft adjustment components. There are four cable support shafts 7, each positioned on both sides of the through hole of the guide frame base plate 1 via four sets of support shaft adjustment components. Two cable support shafts 7 are vertically positioned on one side of the guide frame base plate 1, located on both sides of the through hole; the other two are horizontally positioned on the other side, located above and below the through hole. The four cable support shafts 7 form a "well" shaped structure. This arrangement allows for flexible adjustment of the size and position of the central hole to accommodate cables of different thicknesses. The cable support shafts 7 are rotatably connected to the main shaft via bearings, and one end of the main shaft is fixedly connected to the cable support shaft moving block 3. This rotatable connection design reduces friction during cable insertion and removal, while extending the service life of the equipment.

[0021] The support shaft adjustment assembly includes a guide rail bracket 2, a cable support shaft moving block 3, an adjusting screw bracket 4, a moving block sliding rod 5, and a moving block adjusting screw 6. The guide rail bracket 2 is fixedly connected to the edge of the guide frame base plate 1, and the adjusting screw bracket 4 is fixedly connected to the middle edge of the guide frame base plate 1. There are two moving block sliding rods 5, each fixedly connected at both ends to the guide rail bracket 2 and the adjusting screw bracket 4 respectively, passing through and slidably connecting to the cable support shaft moving block 3. The surface of the moving block sliding rod 5 is polished to reduce friction with the cable support shaft moving block 3, thereby improving the smoothness of sliding. The two ends of the moving block adjusting screw 6 are rotatably connected to the guide rail bracket 2 and the adjusting screw bracket 4, and the middle section is threadedly connected to the cable support shaft moving block 3. The thread of the moving block adjusting screw 6 adopts a trapezoidal thread design to improve stability and accuracy during adjustment. When the moving block adjusting screw 6 is rotated, the cable support shaft moving block 3 slides along the moving block sliding rod 5, thereby adjusting the position of the cable support shaft 7. This combination of threaded adjustment and sliding connection simplifies the adjustment process of the cable support shaft 7 position and improves operational efficiency.

[0022] In practical applications, the guide frame assembly works as follows: the cable passes through the cable shielding tape winding machine 8 from the inlet / outlet tube 12 of the shielding tape winding machine, and then exits from the outlet tube 12 of the cable shielding tape winding machine 8. Inside the cable shielding tape winding machine 8, the winding mechanism rotates, wrapping the shielding tape around the outer layer of the cable. Due to the different thicknesses of the cables, the size of the inlet / outlet tube 12 of the shielding tape winding machine cannot directly adapt to the needs of all cables. Therefore, by rotating the adjusting screw 6 of the moving block, the cable support shaft moving block 3 slides along the sliding rod 5 of the moving block, thereby adjusting the position of the cable support shaft 7. The two cable support shafts 7 on one side move to both sides, and the two cable support shafts 7 on the other side also move to both sides, thereby adjusting the size and position of the central hole of the "well" shaped structure. Through the above adjustment steps, the guide frame assembly can accurately adapt to cables of different thicknesses, ensuring smooth and unobstructed cable insertion and exit.

[0023] The adjustment process of the cable support shaft 7 includes the following steps: S1, determine the thickness of the cable and calculate the size and position of the holes in the "well" shaped structure to be adjusted; S2, rotate the adjusting screw 6 of the moving block to make the moving block 3 slide along the sliding rod 5 of the moving block; S3, confirm whether the position of the cable support shaft 7 meets the requirements by observation or measurement; S4, repeat the above steps until the position of all cable support shafts 7 is adjusted to the correct position. Through the above steps, the guide frame assembly can accurately adjust the position of the cable support shaft 7 to ensure smooth and unobstructed cable insertion and exit.

[0024] The guide frame base plate 1 has multiple mounting holes on both sides of the through hole for fixing the guide rail bracket 2 and the adjusting screw bracket 4. The diameter and spacing of the mounting holes are designed according to actual needs to meet the installation requirements of different equipment models. A sealing ring is provided on the inner side of the guide frame connecting flange 10 to prevent dust and impurities from entering the guide frame assembly. This sealing design improves the protective performance of the guide frame assembly and extends its service life.

[0025] The beneficial effects of this utility model are as follows: First, by adjusting the position of the cable support shaft 7 through the support shaft adjustment assembly, the guide frame assembly can adapt to cables of different thicknesses, eliminating the need for frequent sleeve replacements and significantly improving the equipment's adaptability. Second, the combination of threaded adjustment and sliding connection simplifies the adjustment process of the cable support shaft 7, improving operational efficiency. Third, the cable support shaft 7 is rotatably connected to the main shaft via bearings, reducing friction during cable insertion and removal and extending the equipment's service life. Finally, the bracket assembly adopts a modular design, with components connected by detachable fixing methods, facilitating assembly and maintenance and further enhancing the equipment's practicality.

[0026] In practical applications, the guide frame assembly of this invention is suitable for cable shielding tape winding machines 8 of various specifications. For example, in the actual production of a cable manufacturing plant, the diameter of the cables ranges from 5mm to 20mm. By using the guide frame assembly of this invention, operators can quickly adjust the position of the cable support shaft 7 according to the diameter of the cable without changing different inlet and outlet pipes, thereby significantly shortening the equipment adjustment time and improving production efficiency. In addition, since the cable support shaft 7 is rotatably connected to the main shaft through bearings, there is almost no additional friction during the cable insertion and exit process, further reducing equipment wear and extending service life.

[0027] In summary, this utility model, through structural optimization design of the guide frame assembly, solves the problems of poor adaptability, troublesome sleeve replacement, and high friction in the prior art, providing reliable technical support for the efficient operation of cable shielding tape winding machines.
