Description

Technical Field

[0001] This invention belongs to the field of cable processing and manufacturing, specifically a cable core coating and forming device for cable processing. Background Technology

[0002] Cables typically consist of a conductor, insulation layer, shielding layer, and sheath. The conductor is the core of the cable, made of conductive materials such as copper or aluminum, and is used to transmit current or signals. The insulation layer tightly wraps around the conductor, providing electrical insulation to prevent leakage or short circuits, and is made of materials such as cross-linked polyethylene. The shielding layer is commonly found in cables that require electromagnetic interference resistance and is made of metal braided mesh or foil to reduce external interference. The sheath, as the outermost layer of protection, is made of materials such as polyethylene and polyvinyl chloride to resist mechanical damage, chemical corrosion, and environmental effects, ensuring the reliability and durability of the cable.

[0003] In existing technologies, to improve the insulation performance and protection of cables, multiple layers of protective tape made of materials such as cross-linked polyethylene and polyvinyl chloride are wrapped around their exterior. This requires a wrapping machine to wrap the cable wire. The wrapping machine mainly includes a wrapping mechanism and a winding device. Its working principle is as follows: First, the cable is passed through the rotating head of the wrapping mechanism. Then, the strip material is placed on the rotating head. Subsequently, the motor drives the rotating head to rotate, and in conjunction with the winding device, it pulls the cable core, so that the strip material is evenly and tightly wrapped around the surface of the core in a spiral, thereby completing the wrapping of the cable core.

[0004] In the above technology, the cable core needs to pass through the rotating head of the wrapping mechanism, and the tape used for wrapping also needs to be passed through the cable core. This means that the amount of tape used must be calculated before each installation. Otherwise, the cable core needs to be cut before the tape can be reinstalled. This not only affects the winding efficiency of the cable core, but also causes the final length of the cable to be substandard.

[0005] Therefore, the present invention provides a cable core coating and forming device for cable processing. Summary of the Invention

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 6As shown in the embodiment of the present invention, a cable core coating forming device for cable processing includes a worktable 1; a drive tube 2 is rotatably connected to the top surface of the worktable 1, and the drive tube 2 is driven by a servo motor; a driven frame 3 is mounted on the top of the drive tube 2; a pair of base plates 4 are slidably connected to the bottom of the driven frame 3; mounting holes 5 are provided at the ends of the two base plates 4 that are far apart from each other, and both mounting holes 5 are fixed to the driven frame 3 by bolts; an annular groove 6 is provided on the surface of the drive tube 2 at the corresponding position of the base plate 4, and the annular groove 6 is adapted to the base plate 4; a support plate 7 is fixedly connected to one side of the top surface of the worktable 1; the top and bottom of the drive tube 2 are both Guide wheels 8 are provided, and two guide wheels 8 are rotatably connected to the bottom of the support plate 7 and the workbench 1, respectively; the top surface of the driven frame 3 is fixedly connected to a top plate 9 by bolts; a through hole 10 is opened on the surface of the top plate 9 at the corresponding position of the drive tube 2; guide rollers 12 are installed on the top of both the top plate 9 and the driven frame 3; a sleeve 13 is fixedly connected to the top surface of the workbench 1 at the corresponding position of the drive tube 2; during operation, in order to avoid insufficient wrapping material, which would require cutting the cable to add more material, the embodiment of the present invention can be used. First, the user needs to loosen the bolts between the base plate 4 and the driven frame 3, and then move the two base plates 4 away from the drive tube 2. The user can then place the two strips to be used onto the drive tube 2, and then pull one of them to the driven frame 3. Next, the two base plates 4 are joined together, inserting the base plates 4 into the annular groove 6 on the surface of the drive tube 2. This fixes one strip to the driven frame 3. The user can then pass the cable core to be wrapped through the drive tube 2 and wrap it around the surfaces of the two guide wheels 8. The two guide wheels 8 pull the cable core. The strip is then drawn and passed through the surfaces of the guide rollers 12 and fixed to the surface of the cable core. The drive tube 2 and the external traction assembly are then activated simultaneously. The drive tube 2 drives the driven frame 3 and the strip inside it to rotate, while the traction assembly pulls the cable core, allowing it to... Guided by the guide wheel 8, the strip passes vertically through the drive tube 2, allowing it to evenly cover the surface of the cable core. When the strip is used up, the user can loosen the bolts at the base plate 4 and pull the strip to be used at the bottom of the base plate 4 into the driven frame 3. Then, the base plate 4 is reinserted into the annular groove 6 on the surface of the drive tube 2 to complete the reloading of the strip. This effectively reduces the need to cut the cable core due to insufficient strip and reduces the difficulty of strip replacement while ensuring the integrity of the cable core. The sleeve 13 on the top surface of the workbench 1 can separate the strip from the drive tube 2, thereby preventing the drive tube 2 from being affected by the strip at the bottom of the base plate 4 when it rotates.

[0023] like Figure 2 , Figure 6 and Figure 7As shown, a pair of sliding columns 14 are slidably connected to the top surface of the workbench 1; connecting columns 15 are installed on the top surfaces of the two sliding columns 14; mounting grooves 16 are formed on the top surfaces of the connecting columns 15; a push rod 17 is slidably connected inside the mounting groove 16; a spring 18 is installed between the push rod 17 and the bottom of the mounting groove 16; a gear 19 is rotatably connected inside the workbench 1; toothed plates 20 are meshed on both sides of the gear 19, and the two toothed plates 20 are respectively fixedly connected to the two sliding columns 14; during operation, when the user needs to slide the two base plates 4, the user needs to first press the push rod 17 into the mounting groove 16, and After compressing the spring 18, the sliding column 14 is moved to the mounting holes 5 on the surfaces of the two base plates 4. Then, the user releases the push rod 17, the spring 18 returns to its original position, and the push rod 17 is positioned out of the mounting groove 16 and finally inserted into the mounting holes 5 on the surface of the base plate 4. At this time, the user slides one side of the sliding column 14. Since the two sliding columns 14 are connected by the gear 19 and the toothed plate 20, the user only needs to move one side of the sliding column 14, and the other side of the sliding column 14 will also move synchronously. In turn, the two push rods 17 synchronously drive the two base plates 4 to move towards or away from each other, so that the user can easily pull open or close the two base plates 4.

[0024] like Figures 7 to 8 As shown, the surface of the connecting column 15 is provided with a guide groove 21; the guide groove 21 is L-shaped and includes a horizontal part and a vertical part; a pair of symmetrically arranged guide rods 22 are fixedly connected to the bottom of the pressing rod 17, and the guide rods 22 are located in the guide groove 21; during operation, when the user needs to fix the pressing rod 17 in the mounting groove 16, the user needs to press down the pressing rod 17, which drives the guide rods 22 to descend along the guide groove 21 until they move to the horizontal part of the guide groove 21. Then the user rotates the pressing rod 17, which drives the guide rods 22 to move into the horizontal part of the guide groove 21, thereby fixing the position of the pressing rod 17, so that the user does not need to press the pressing rod 17 continuously, thus simplifying the user's operation.

[0025] like Figures 7 to 8 As shown, connecting plates 23 are rotatably connected to both sides of the connecting column 15; a slot 24 is provided at the bottom of the connecting column 15, and the slot 24 is adapted to the bolt end between the base plate 4 and the driven frame 3; during operation, when the user needs to tighten the bolt at the end of the base plate 4, the user can tighten the connecting column 15 at the top of the sliding column 14, align the slot 24 at the bottom of the connecting column 15 with the bolt at the end of the base plate 4, and then rotate the top rod 17 so that the guide rod 22 on the surface of the top rod 17 moves from the horizontal part of the guide groove 21 to the vertical part. At this time, the spring 18 will push the top rod 17 out, thereby lifting the connecting column 15 and the connecting plate 23, and locking the slot 24 at the end of the connecting column 15 onto the bolt at the base plate 4, thereby fixing the bolt and making it convenient for the user to tighten the bolt.

[0026] like Figure 8 As shown, the top surface of the sliding column 14 has a limiting hole 25, which is adapted to the top rod 17; the end of the connecting column 15 near the slot 24 is fixed with a magnetic ring 26, and the sliding column 14 is made of magnetized metal; during operation, when the slot 24 of the connecting column 15 faces the top of the sliding column 14, the connecting column 15 will attract the sliding column 14 to each other, thereby fixing the connecting column 15 and preventing the connecting column 15 from rotating when the top rod 17 moves the base plate 4. When the user rotates the connecting column 15 and inserts the top rod 17 into the limiting hole 25 at the top of the sliding column 14, the connecting column 15 is restricted again, preventing the connecting column 15 from deflecting when the user rotates the bolt.

[0027] like Figure 2 and Figure 9 As shown, a pair of support rods 27 are installed on the top surface of the workbench 1 at the bottom of the driven frame 3, and the planes on which the two support rods 27 are located are perpendicular to the planes on which the two sliding columns 14 are located; a support block 28 is installed on the top surface of the support rods 27; a limiting ring 29 is fixedly connected to the bottom surface of the driven frame 3; a limiting groove 30 is opened on the top surface of the support block 28 at the corresponding position of the limiting ring 29, and the limiting groove 30 is adapted to the limiting ring 29; the inner wall and bottom surface of the limiting groove 30 are both rolled with balls 31; during operation, when the driven frame 3 rotates, the support rods 27 will restrict the limiting ring 29 on the bottom surface of the driven frame 3 through the support block 28 and the limiting groove 30 on their top surfaces, thereby preventing excessive shaking when the driven frame 3 rotates, which would cause the strip to not be tightly wrapped around the surface of the cable core, while the balls 31 in the mounting groove 16 can reduce the friction of the limiting ring 29 when it slides therein, thereby reducing the wear on both.

[0028] like Figure 2 and Figure 9As shown, a receiving groove 32 is provided on the top surface of the workbench 1 at the position corresponding to the support rod 27; the support rod 27 is rotatably connected in the receiving groove 32, and the support rod 27 is rotatably connected to the support block 28; a moving plate 33 is threadedly connected to the surface of the support rod 27; a straight rod 34 is fixedly connected in the receiving groove 32, and the moving plate 33 is slidably connected to the straight rod 34; a support column 35 is installed at the end of the moving plate 33 away from the support rod 27; the two support rods 27 are driven by a servo motor inside the workbench 1 through a gear set 19; during operation, when the user needs to lift the strip located at the bottom of the base plate 4 into the driven frame 3, the user can use the servo motor to drive the two support rods 27 to rotate and the straight rod 34 to restrict the movement of the moving plate 33 and the support column 35 on the surface of the support rod 27, thereby lifting the strip at the top of the receiving groove 32. This eliminates the need for manual operation by the user, simplifying the user's operation and making it easier for the user to control the posture of the strip when it rises, preventing it from tilting and getting stuck in the annular groove 6 on the surface of the drive tube 2.

[0029] like Figure 9 As shown, a diagonal rod 36 is fixedly connected to the top surface of the movable plate 33, and the end of the diagonal rod 36 away from the movable plate 33 is adapted to the support column 35; the support column 35 is rotatably connected to the movable plate 33; elastic bands 37 are fixedly connected to both sides of the support column 35, and the ends of the two elastic bands 37 away from the support column 35 are respectively fixedly connected to both sides of the movable plate 33; during operation, after the support column 35 raises the strip into the driven frame 3, the user also needs to control the two base plates 4 to move towards each other. At this time, the base plates 4 press against the support column 35 and cause the support column 35 to rotate away from the diagonal rod 36, so that the two base plates 4 can be smoothly engaged in the annular groove 6. When the strip rises on the support rod 27, the elastic band 37 will pull the support rod 27 towards the diagonal rod 36, so that the diagonal rod 36, the movable plate 33 and the support plate 7 form a triangle, thereby enabling the support column 35 to support the strip more stably.

[0030] like Figure 2 , Figure 3 and Figure 10As shown, the top plate 9 has mating grooves 38 on both sides of the through hole 10; the drive tube 2 is fitted with a sleeve 381; a mating plate 39 is fixedly connected to the sleeve 38 at the corresponding position of the mating groove 38, and the mating plate 39 is adapted to the mating groove 38; the top of the sleeve 381 is threaded with a pressing tube 40, and the outer diameter of the pressing tube 40 is larger than the through hole 10; during operation, after the user installs the strip in the driven frame 3, the user also needs to insert the sleeve 381 into the through hole 10 and insert the mating plate 39 on its surface into the mating groove 38, and then the user screws in the pressing tube 40, thereby pressing the sleeve 381 onto the top plate 9, thus connecting the drive tube 2 and the driven frame 3 together, thereby avoiding the problem of slippage that easily occurs when the bottom plate 4 and the driven frame 3 are rotated only through the annular groove 6.

[0031] like Figure 10 As shown, a pressure plate 41 is threadedly connected to the surface of the sleeve 381 near the bottom; the pressure plate 41 is arranged in a ring shape; during operation, after the user has installed the sleeve 381 and the extrusion tube 40, the pressure plate 41 at the bottom of the sleeve 381 will press against the surface of the strip, thereby firmly fixing the strip in the driven frame 3, preventing the strip from shaking in the driven frame 3 when the driven frame 3 rotates, which would prevent the strip from being tightly wound on the surface of the cable core. At the same time, turning the pressure plate 41 can also adjust the position of the pressure plate 41 on the surface of the sleeve 381, thereby adapting to strips of different heights.

[0032] During operation, to avoid insufficient wrapping tape, which necessitates cutting the cable to add more tape, this embodiment of the invention can be used. First, the user needs to loosen the bolts between the base plate 4 and the driven frame 3. Then, the two base plates 4 are moved away from the drive tube 2. At this point, the user can place the two tapes to be used onto the drive tube 2, and then pull one of them to the driven frame 3. Subsequently, the two base plates 4 are closed together, and the base plates 4 are inserted into the annular groove 6 on the surface of the drive tube 2. This fixes one tape to the driven frame 3. Then, the user can pass the cable core to be wrapped through the drive tube 2 and wrap it around the surface of the two guide wheels 8. The two guide wheels 8 pull the cable core, and then the tape is drawn and fixed to the surface of the cable core after passing through the surfaces of each guide roller 12. Then, the drive tube 2... Simultaneously activated with the external traction component, the drive tube 2 drives the driven frame 3 and the strip inside it to rotate. The traction component pulls the cable core, allowing it to pass vertically through the drive tube 2 under the guidance of the guide wheel 8. This ensures that the strip evenly covers the surface of the cable core. When the strip is used up, the user can loosen the bolts at the base plate 4 and pull the strip to be used at the bottom of the base plate 4 into the driven frame 3. Then, the base plate 4 is reinserted into the annular groove 6 on the surface of the drive tube 2 to complete the reloading of the strip. This effectively reduces the need to cut the cable core due to insufficient strip and reduces the difficulty of strip replacement while ensuring the integrity of the cable core. The sleeve 13 on the top surface of the workbench 1 can separate the strip from the drive tube 2, thereby preventing the drive tube 2 from being affected by the strip at the bottom of the base plate 4 when it rotates.

[0033] When the user needs to slide the two base plates 4, the user first needs to press the push rod 17 into the mounting groove 16 and compress the spring 18. Then, the user moves the sliding column 14 to the mounting hole 5 on the surface of the two base plates 4. Then the user releases the push rod 17, the spring 18 returns to its original position, and the push rod 17 is fixed out of the mounting groove 16 and finally inserted into the mounting hole 5 on the surface of the base plate 4. At this time, the user slides the sliding column 14 on one side. Since the two sliding columns 14 are connected by the gear 19 and the toothed plate 20, the user only needs to move the sliding column 14 on one side, and the sliding column 14 on the other side will also move synchronously. In turn, the two push rods 17 synchronously drive the two base plates 4 to move towards or away from each other, so that the user can easily pull the two base plates 4 apart or fasten the two base plates 4 together.

[0034] When the user needs to fix the push rod 17 in the mounting groove 16, the user needs to press down the push rod 17, which will drive the guide rod 22 to descend along the guide groove 21 until it moves to the horizontal part of the guide groove 21. Then the user rotates the push rod 17, which will drive the guide rod 22 to move into the horizontal part of the guide groove 21, thereby fixing the position of the push rod 17. This eliminates the need for the user to keep pressing the push rod 17, thus simplifying the user's operation.

[0035] When the user needs to tighten the bolts at the end of the base plate 4, the user can tighten the connecting post 15 at the top of the sliding post 14, align the slot 24 at the bottom of the connecting post 15 with the bolt at the end of the base plate 4, and then rotate the top rod 17 so that the guide rod 22 on the surface of the top rod 17 moves from the horizontal part of the guide groove 21 to the vertical part. At this time, the spring 18 will push the top rod 17 out, thereby lifting the connecting post 15 and the connecting plate 23, and locking the slot 24 at the end of the connecting post 15 into the bolt at the base plate 4, thereby fixing the bolt and making it convenient for the user to tighten the bolt.

[0036] When the connecting post 15 has a slot 24 facing the top of the sliding post 14, the connecting post 15 will attract the sliding post 14 to each other, thereby fixing the connecting post 15 and preventing the connecting post 15 from rotating when the top rod 17 moves the base plate 4. When the user rotates the connecting post 15 and inserts the top rod 17 into the limiting hole 25 at the top of the sliding post 14, the connecting post 15 is restricted again, preventing the connecting post 15 from deflecting when the user rotates the bolt.

[0037] When the driven frame 3 rotates, the support rod 27 restricts the limiting ring 29 on the bottom surface of the driven frame 3 through the support block 28 on its top surface and the limiting groove 30, thereby preventing excessive shaking when the driven frame 3 rotates, which would prevent the strip from tightly wrapping the surface of the cable core. Meanwhile, the ball bearing 31 in the mounting groove 16 can reduce the friction when the limiting ring 29 slides in it, thereby reducing the wear on both.

[0038] When the user needs to lift the strip located at the bottom of the base plate 4 into the driven frame 3, the user can drive the two support rods 27 to rotate and the straight rod 34 to lift the moving plate 33 and support column 35 on the surface of the support rods 27, thereby lifting the strip at the top of the receiving groove 32. This eliminates the need for manual operation by the user, simplifying the operation and making it easier for the user to control the posture of the strip when it rises, preventing it from tilting and getting stuck in the annular groove 6 on the surface of the drive tube 2.

[0039] After the support column 35 raises the strip into the driven frame 3, the user needs to control the two base plates 4 to move towards each other. At this time, the base plates 4 press against the support column 35 and cause the support column 35 to rotate away from the inclined bar 36, so that the two base plates 4 can be smoothly engaged in the annular groove 6. When the support rod 27 raises the strip, the elastic band 37 will pull the support rod 27 towards the inclined bar 36, so that the inclined bar 36, the moving plate 33 and the support plate 7 form a triangle, so that the support column 35 can support the strip more stably.

[0040] After the user installs the strip into the driven frame 3, the user also needs to insert the sleeve 381 into the through hole 10 and insert the mating plate 39 on its surface into the mating groove 38. Then the user screws in the extrusion tube 40, thereby pressing the sleeve 381 onto the top plate 9, thus connecting the drive tube 2 and the driven frame 3 together. This avoids the problem of slippage that can easily occur when the bottom plate 4 and the driven frame 3 are rotated only through the annular groove 6.

[0041] After the user has installed the sleeve 381 and the extrusion tube 40, the pressure plate 41 at the bottom of the sleeve 381 will press against the surface of the strip, thereby firmly fixing the strip in the driven frame 3. This prevents the strip from shaking inside the driven frame 3 when the driven frame 3 rotates, which would prevent the strip from being tightly wound on the surface of the cable core. At the same time, turning the pressure plate 41 can also adjust the position of the pressure plate 41 on the surface of the sleeve 381, thereby adapting to strips of different heights.
