Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts disclosed in this invention.

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0038] Reference Figure 1 - Figure 12 This invention provides a stranding machine for cable manufacturing, including a wire feeding module, a stranding module, and a wire output module. This invention improves the wire feeding module. The stranding module and the wire output module are both existing technologies, and their specific structures and working principles are existing technologies. The implementation method adopts conventional means and is not shown in the figure, nor will it be described in detail here. The wire feeding module includes a frame 1, on which a fixed plate 2 is fixed. A drive motor 22 is installed on one side of the fixed plate 2, and a rotatable rotating plate 3 is provided on the other side. The output shaft of the drive motor 22 is connected to the rotating plate 3. When the drive motor 22 is running, it can drive the rotating plate 3 to rotate. The rotating plate 3 is coaxial with the fixed plate 2. Several wire feeding components are provided on the rotating plate 3, and the several wire feeding components are distributed in a circumferential array around the center position of the rotating plate 3.

[0039] Each wire feeding assembly includes a mounting frame 41 and a wheel axle 51. The wheel axle 51 is detachably mounted on the mounting frame 41. A winding roller 53 is fixedly sleeved on the wheel axle 51. The raw material wire for making cables is wound onto the winding roller 53. Slots 52 are provided at both ends of the wheel axle 51. A fixing structure is provided on the mounting frame 41 to fix the wheel axle 51. Figure 10As shown, the fixing structure includes two mounting ports 42, which are respectively opened at both ends of the mounting frame 41. A locking rod 43 is slidably disposed in each mounting port 42, and a collar 44 is fixedly fitted onto each locking rod 43. Both collars 44 are connected to the mounting frame 41 via first springs 45. Under the elastic force of the two first springs 45, the two locking rods 43 always tend to move closer to each other. When the two slots 52 on the axle 51 move to a position directly opposite the two mounting ports 42, the two locking rods 43 can be inserted into the two slots 52 respectively. At this time, the two locking rods 43 together fix the axle 51, thus fixing the axle 51 to the mounting frame 41, forming a... Figure 10 As shown, both the locking rod 43 and the slot 52 have circular cross-sections, which allows the axle 51 to rotate freely on the mounting bracket 41. A connecting plate 411 is fixed to the side of the mounting bracket 41, and the connecting plate 411 is connected to the rotating plate 3.

[0040] When manufacturing cables, the drive motor 22 runs and drives the rotating plate 3 to rotate. The rotating plate 3 can drive several winding rollers 53 on it to rotate synchronously. Multiple single wires are drawn out from the winding rollers 53 respectively. Under the action of the stranding module, the multiple single wires rotate around the central reinforcing core to form a spiral stranded structure. The stranded cable is discharged through the output module and finally evenly wound onto the take-up reel.

[0041] The mounting bracket 41 is provided with a disassembly structure, which is used to release the two locking rods 43 from locking the wheel axle 51. The disassembly structure includes a guide rod 61, which is fixed to the side of the mounting bracket 41. Two sliders 62 are slidably arranged on the guide rod 61. The sliders 62 are connected to the locking rods 43 at their diagonal positions through a connecting rod 63. When the two sliders 62 approach each other, the two locking rods 43 can move away from each other.

[0042] A mounting bracket 412 is fixed on the mounting bracket 41. The mounting bracket 412 has holes and a pushing structure for driving two sliders 62. The pushing structure includes a vertical rod 71 that passes through the holes and slides within them. A lifting block 72 is fixed to the bottom of the vertical rod 71. Two connecting rods 75 are rotatably mounted on the lifting block 72. The ends of the two connecting rods 75 away from the lifting block 72 are rotatably connected to the two sliders 62. The lifting block 72 is connected to the mounting bracket 412 via a second spring 73. A push rod 74 is fixed to the top of the vertical rod 71, and the push rod 74 has an L-shaped structure. Under the elastic force of the second spring 73, the lifting block 72 always tends to move away from the mounting bracket 412, ensuring that the two sliders 62 always move relative to each other. As the lifting block 72 moves toward the fixed frame 412, it can pull the two sliders 62 closer together via the two connecting rods 75. Due to the special position design of the two connecting rods 63, when the two sliders 62 are close together, the two locking rods 43 can be driven away from each other via the two connecting rods 63. When the lifting block 72 moves to the limit position near one end of the fixed frame 412, the ends of the two locking rods 43 can be completely retracted into the two mounting holes 42. In this case, the axle 51 can move between the two mounting holes 42. During the movement of the slider 62, the guide rod 61 provides guidance. The side of the slider 62 fits against the side of the mounting frame 41, which can ensure the stability of the slider 62 during the movement.

[0043] A control component is provided on the side of the fixed plate 2. The control component includes an arc-shaped slide 21 and two protrusions 23. The arc-shaped slide 21 is formed on the fixed plate 2, and a guide block 84 (e.g., ...) is slidably disposed in the arc-shaped slide 21. Figure 5 As shown), both ends of the guide block 84 extend to the outside of the arc-shaped slide 21, and one end of the guide block 84 is fixed with a mounting base 81 (as shown). Figure 12 As shown), a limiting plate 85 is fixed at one end. Both the mounting base 81 and the limiting plate 85 are in contact with the fixed plate 2. A sliding plate 82 is slidably mounted on the mounting base 81, and the sliding plate 82 has an arc surface. The sliding plate 82 and the mounting base 81 are connected by a first tension spring 83. Two protrusions 23 are fixed at the upper and lower ends of the fixed plate 2, respectively. Each protrusion 23 has an arc surface. Under the elastic force of the first tension spring 83, the sliding plate 82 always tends to move closer to the fixed plate 2. When the sliding plate 82 is in the state of moving closer to the fixed plate 2, the vertical plane where the sliding plate 82 is located is offset from the vertical plane where the push rod 74 is located. Figure 3As shown, dashed line a represents the vertical plane where the sliding plate 82 is located, and dashed line b represents the vertical plane where the push rod 74 is located. In this state, the push rod 74 will not contact the sliding plate 82 during the rotation of the mounting bracket 41. When the mounting base 81 moves along the arc-shaped slide 21, the guide block 84 slides in the arc-shaped slide 21, providing guidance for the mounting base 81. The limiting plate 85 is set to prevent the guide block 84 from falling out of the arc-shaped slide 21. Furthermore, the side of the guide block 84 is in contact with the inner wall of the arc-shaped slide 21, which makes the two have a large frictional force. This frictional force plays a role in fixing the position of the guide block 84, so that the guide block 84 and the mounting base 81 are in contact. The sliding plate 82 will not move under non-human-caused conditions, allowing staff to flexibly adjust the positions of the mounting base 81 and the sliding plate 82. In addition, anti-slip textures can be provided on the side of the guide block 84 and the inner wall of the arc-shaped slide 21 to increase the friction between them. Furthermore, a handle is installed on the side of the limiting plate 85 to facilitate staff adjustment of the position of the sliding plate 82. A limiting port is provided on the mounting base 81, and a limiting strip is slidably installed in the limiting port. The limiting strip is connected to the sliding plate 82. An anti-detachment frame is fixed at the end of the limiting strip away from the sliding plate 82 to prevent the limiting strip from falling out of the limiting port. When the sliding plate 82 moves on the mounting base 81, the limiting port and the limiting strip provide a limit.

[0044] The cable stranding machine proposed in this invention has the function of quickly disassembling the winding roller 53. In the initial state, such as Figure 2 As shown, the sliding plate 82 is positioned offset from the two protrusions 23. Under the elastic force of the first tension spring 83, the sliding plate 82 is close to the fixed plate 2. In this state, the push rod 74 will not contact the sliding plate 82 when rotating with the mounting bracket 41. After the wire on the winding roller 53 is consumed, the operator first turns off the drive motor 22, then adjusts the position of the rotating plate 3 until there are no obstructions in front of the lower protrusion 23. Next, the operator pulls the handle on the limiting plate 85, causing the limiting plate 85, guide block 84, and mounting base 81 to move. When the sliding plate 82 moves to the position directly opposite the protrusion 23 at the lower end, the arc surface of the protrusion 23 at the lower end will press against the sliding plate 82, causing the sliding plate 82 to move away from the fixed plate 2 and stretch the first tension spring 83. When the sliding plate 82 moves to the position directly opposite the protrusion 23 at the lower end, the protrusion 23 can abut against the sliding plate 82. In this case, the sliding plate 82 can move onto the rotation path of several push rods 74. That is, during the rotation of the push rods 74, the end of the push rod 74 away from the vertical rod 71 will contact the arc surface of the sliding plate 82.

[0045] After adjusting the position of the sliding plate 82, the operator controls the rotating plate 3 to rotate. As the rotating plate 3 rotates, several mounting brackets 41 on it rotate accordingly. The mounting brackets 41 have a U-shaped structure. When the mounting bracket 41 rotates to the bottom position of the fixed plate 2, the opening of the mounting bracket 41 faces downwards, and the push rod 74 contacts the arc surface of the sliding plate 82 and moves along the arc surface of the sliding plate 82. Figure 8 As shown, when the push rod 74 moves, it can drive the vertical rod 71 to move, and the lifting block 72 connected to the vertical rod 71 moves accordingly. This causes the two sliders 62 to move closer to each other, and eventually causes the two locking rods 43 to move away from each other. When the ends of the two locking rods 43 are completely retracted into the two mounting ports 42, the two locking rods 43 will exit from the two slots 52 respectively. At this time, the two locking rods 43 no longer provide constraints on the wheel axle 51, and the wheel axle 51 can fall naturally under the action of gravity. Therefore, whenever the mounting frame 41 rotates to the bottom position of the fixed plate 2, the two locking rods 43 will release the locking effect on the wheel axle 51. In summary, after adjusting the position of the sliding plate 82, the operator only needs to control the rotating plate 3 to rotate slowly to achieve quick disassembly of several winding rollers 53. This method replaces the traditional screw fixing, which not only requires no tools, but is also convenient and quick, significantly shortening the machine downtime due to the replacement of winding rollers 53 and ensuring the working efficiency of the device.

[0046] Similarly, when installing the winding roller 53 fully wound with wire, the operator adjusts the sliding plate 82 to face the protrusion 23 located at the upper end of the fixed plate 2. When the mounting bracket 41 rotates to a position close to the upper protrusion 23, the push block can also contact the arc surface of the sliding plate 82, and the two locking rods will move away from each other. At this time, the operator can place the axle 51 of the winding roller 53 between the two mounting openings 42, and simultaneously control the rotating plate 3 to rotate. When the push rod 74 is misaligned with the sliding plate 82, the lifting block 72 resets under the action of the second spring 73, and the two locking rods 43 also reset under the action of the corresponding first spring 45. This allows... The two locking rods 43 can be inserted into the two slots 52 at both ends of the axle 51 respectively, so as to quickly fix the axle 51. It should be noted that the mounting bracket 41 can be provided with a positioning structure for positioning the winding wheel. Under the action of the positioning structure, when the axle 51 is placed on the mounting bracket 41, the slots 52 at both ends of the axle 51 are exactly aligned with the two locking rods 43 respectively. This allows the two locking rods 43 to be smoothly inserted into the two slots 52 while rotating with the rotating plate 3. The positioning structure can be a positioning protrusion or other structure with positioning function. This is the prior art and is not shown in the figure. It will not be described in detail here.

[0047] The rotating plate 3 has several guide rails 91 on its side, and each guide rail 91 has a sliding seat. Several connecting plates 411 are fixed on the sliding seats. The guide rails 91 and the sliding seats allow the connecting plates 411 to slide on the rotating plate 3. The connecting plates 411 are connected to the rotating plate 3 by a second tension spring 92. Under the elastic force of the second tension spring 92, the connecting plates 411 always tend to move closer to the center of the rotating plate 3. A bladder 911 is fixed to the end of the guide rail 91 away from the center of the rotating plate 3, and the bladder 911 is positioned directly opposite the connecting plate 411. A fixing block 741 is fixedly sleeved on the push rod 74, and the fixing block 741 has a slot 742 (e.g., Figure 6 As shown), a telescopic rod 93 is fixed on the connecting plate 411. The telescopic rod 93 is connected to the bladder body 911 through a connecting pipe 931. A locking block 94 is fixed to the telescopic end of the telescopic rod 93, and the locking block 94 is set opposite to the locking slot 742.

[0048] To improve the stability of the winding roller 53 during rotation, this invention designs a structure for locking the position of the push rod 74. When the rotating plate 3 and several winding rollers 53 rotate together, the position of the push rod 74 is fixed. When the push rod 74 is locked, the positions of the vertical rod 71, the lifting block 72, the two sliders 62, and the two locking rods 43 are also locked. This ensures the stability of the two locking rods 43 during the rotation of the winding roller 53. Based on the quick-release function of the winding roller 53, this provides a guarantee for the stability of the winding roller 53 during operation. Specifically, when the rotating plate 3 and several winding rollers 53 are in a stationary state or a low-speed rotating state, under the elastic force of the second tension spring 92, the connecting plate 411 is positioned close to the center of the rotating plate 3. At this time, the connecting plate 411 and the bladder 911 are separated (e.g., Figure 6As shown, the telescopic rod 93 is in the retracted state, and the locking block 94 is not locked into the locking groove 742, which allows the push rod 74 to move freely, so that the staff can disassemble and assemble the winding roller 53. When the rotating plate 3 and several winding rollers 53 are rotating at high speed, the mounting frame 41 will overcome the elastic force of the second tension spring 92 under the action of centrifugal force. This causes the connecting plate 411 to move away from the center of the rotating plate 3. At this time, the connecting plate 411 will squeeze the bladder 911. The gas in the bladder 911 can enter the telescopic rod 93 through the connecting pipe 931, causing the telescopic end of the telescopic rod 93 to extend. The telescopic end of the telescopic rod 93 can drive the locking block 94 to move, so that the locking block 94 is inserted into the slot 742. In this state, the locking block 94 locks the push rod 74. Based on the above process, when the rotating plate 3 is stationary or rotating at low speed, the position of the push rod 74 is not locked. When the rotating plate 3 rotates at high speed (when the machine is in working state), the position of the push rod 74 is locked. When the push rod 74 is locked, the positions of the two locking rods 43 are locked accordingly, thereby ensuring the stability of the winding roller 53 in the high-speed rotating state and preventing the winding roller 53 from falling off and flying away in the high-speed rotating state.
