Description

Technical Field

[0001] This invention relates to, specifically, a novel stranding and brazing device for a cabling machine. Background Technology

[0002] A cabling machine is a piece of equipment used in cable manufacturing. Its main function is to process slender insulated core wires into cables capable of withstanding high pressure. In the cable industry, cabling machines play a crucial role. The cabling process involves twisting the core wires and fillers together to form a cable, then covering it with mica tape and rubber tape to improve the cable's strength and corrosion resistance. Because steel cables have low plasticity, the covering speed of the mica tape cannot be precisely adjusted synchronously when the cable's transmission speed changes. This results in inconsistent tightness of the mica tape wrapping, leading to uneven cable shapes, inconvenience during storage and installation, and the generation of waste. Summary of the Invention

[0003] This invention proposes a novel stranding and bundling device for cable forming machines, which solves the problem in related technologies where the wrapping speed of mica tape is difficult to adjust precisely and synchronously when the cable transmission speed changes. This results in varying degrees of tightness of the mica tape wrapping, causing uneven cable shape, inconvenience in the installation process of storage and transportation, and the generation of waste.

[0004] The technical solution of the present invention is as follows:

[0005] A novel stranding and winding device for a cable-forming machine, used to wind mica tape onto a cable, includes a body having a first cable guide hole for guiding the cable.

[0006] A rotating frame, rotatably mounted on the machine body, has a shaft portion with a wire passage, and is used to mount at least two mica tape rolls.

[0007] A transmission disc is slidably mounted on the rotating frame. When the transmission disc is driven to rotate, it causes the rotating frame to rotate as well. The transmission disc has a transmission part located on its outer edge.

[0008] The drive wheel, located on one side of the machine body, has a truncated cone portion. This truncated cone portion engages in frictional contact with the transmission unit, driving the transmission disc to rotate. As the transmission disc slides, it contacts the truncated cone portion at different positions, changing the transmission ratio.

[0009] A pushing component is used to push the transmission disk to slide.

[0010] As a further technical solution, the driving component includes:

[0011] A drive wheel, rotatably mounted on the machine body, is used to make frictional contact with the cable and be driven to rotate by the cable.

[0012] A rotating disk, which is coaxially arranged with the transmission wheel.

[0013] The throwing blocks are radially slidable on the rotating disk and are arranged in several circular patterns.

[0014] A sliding block is slidably disposed on the machine body and located between the transmission disk and the swing block. The swing block is used to push the sliding block to slide, and the sliding block pushes the transmission disk to slide.

[0015] As a further technical solution, it also includes:

[0016] A thrust bearing is provided on the sliding block and the transmission disk, with one end on the transmission disk and the other end for abutting against the sliding block.

[0017] As a further technical solution, it also includes:

[0018] A first elastic element, one end of which acts on the throwing block and the other end of which acts on the rotating disk, provides a force for the throwing block to slide towards the center of the rotating disk.

[0019] The second elastic element has one end acting on the transmission disk and the other end acting on the rotating frame, providing a force to bring the transmission disk closer to the swing block.

[0020] As a further technical solution, the rotating frame also has a belt coiling section, which is arranged perpendicularly to the rotating shaft of the rotating frame, and there are several belt coiling sections; it also includes a belt guide, which is disposed on the rotating frame and has a belt guide hole for guiding the mica belt after it passes through the belt guide hole.

[0021] As a further technical solution, it also includes:

[0022] A support frame is mounted on the machine body and located on one side of the rotating frame. The support frame has a second wire guide hole, which is coaxially arranged with the first wire guide hole.

[0023] A turntable, which is rotatably mounted on the support frame.

[0024] A fixing component, one end of which is disposed on the guide belt or the rotating frame, and the other end of which is disposed on the turntable.

[0025] As a further technical solution, the rotating frame has a keyway, and the transmission disk has a sliding part, which is slidably disposed in the keyway.

[0026] As a further technical solution, the transmission wheel has an arc-shaped groove, the arc-shaped groove having the same curvature as the cable, and the transmission wheel is provided in several forms.

[0027] As a further technical solution, the guide belt is rhomboid or rectangular.

[0028] As a further technical solution, the system also includes a platform having a mounting cavity, and the transmission wheel is located within the mounting cavity.

[0029] The working principle and beneficial effects of this invention are as follows:

[0030] In this invention, a transmission disc is designed on the rotating frame, and a drive wheel is also provided at the motor output end. Transmission is achieved through frictional contact between the drive wheel and the transmission disc. The drive wheel is fixed in position and tilted so that one side of the truncated cone is always in contact with the transmission disc. The transmission disc can slide on the rotating frame. After the driven component pushes the transmission disc to slide, the contact position with the truncated cone changes, and the ratio of the motor's output speed to the transmission disc's input speed changes. Through this design, the rotational speed of the rotating frame can be precisely adjusted in real time according to the pushing component, avoiding the continuous accumulation of mica tape after a failure during cable winding, and enabling rapid adaptive adjustment after a failure.

[0041] Reference Figures 1-4An embodiment of the invention proposes a novel stranding and winding device for a cable forming machine, used to wind mica tape onto a cable. The device includes a body 1 with a first cable guide hole 101 for guiding the cable. A rotating frame 2 is rotatably mounted on the body 1, and its shaft has a cable guide channel 201. The rotating frame 2 is used to mount at least two mica tape rolls. A transmission disc 3 is slidably mounted on the rotating frame 2. When driven to rotate, the transmission disc 3 drives the rotating frame 2 to rotate. The transmission disc 3 has a transmission part 301 located on its outer edge. A drive wheel 4 is located on one side of the body 1 and has a truncated cone 401. The truncated cone 401 rubs against the transmission part 301 and drives the transmission disc 3 to rotate. After sliding, the transmission disc 3 contacts the truncated cone 401 at different positions, and the transmission ratio changes. A pushing component 5 is used to push the transmission disc 3 to slide.

[0042] In this embodiment, considering that the existing technology uses a method of placing mica tape on a rotating frame 2 and driving the rotating frame 2 to rotate during cable feeding to wind the mica tape onto the cable, the actual cable feeding speed is affected by various factors during production, while the rotation speed of the rotating frame 2 is constant. This can lead to mica tape accumulation or gaps during the winding process, and the malfunction will continue to occur in subsequent mica tape winding processes. This solution designs a transmission disk 3 on the rotating frame 2 and also provides a drive wheel 4 at the motor output end. The drive wheel 4 is used to achieve transmission through frictional contact with the transmission disk 3. The position of the drive wheel 4 is fixed and it is inclined so that one side of the truncated cone 401 is always in contact with the transmission disk 3. The transmission disk 3 can slide on the rotating frame 2. After the driven component 5 pushes the transmission disk 3 to slide, the contact position with the truncated cone 401 changes, and the ratio of the motor output speed to the input speed of the transmission disk 3 changes. Through the above design, the rotation speed of the rotating frame 2 can be precisely adjusted in real time as the pushing component 5 is pushed, avoiding the continuous accumulation of mica tape after a failure during the winding process on the cable, and enabling rapid adaptive adjustment after a failure.

[0043] Furthermore, the driving component 5 includes a transmission wheel 6, which is rotatably mounted on the body 1 for frictional contact with the cable and is driven to rotate by the cable. The rotating disk 7 is coaxially mounted with the transmission wheel 6. The swing block 8 is radially slidably mounted on the rotating disk 7 and is arranged in several circumferences. The sliding block 9 is slidably mounted on the body 1 and is located between the transmission disk 3 and the swing block 8. The swing block 8 is used to push the sliding block 9 to slide, and the sliding block 9 pushes the transmission disk 3 to slide.

[0044] In this embodiment, considering the need to adjust the rotational speed of the rotating frame 2 according to the changes in the cable feed speed, a transmission wheel 6 is designed. The transmission wheel 6 is in frictional contact with the cable, and the transmission wheel 6 is driven to rotate by the cable, converting the cable's movement speed into the rotational speed of the transmission wheel 6. This embodiment also includes a rotating disk 7, within which a swing block 8 is slidably disposed. When the cable feed speed is too fast, the swing block 8 will be subjected to centrifugal force, sliding out of the rotating disk 7 and abutting against a sliding block 9, pushing the sliding block 9, which in turn pushes the transmission disk 3, causing a change in the rotational speed of the rotating frame 2. The sliding block 9 can prevent damage to the device caused by direct collision between the two rotating objects, the rotating disk 7 and the transmission disk 3. The sliding block 9 is only a schematic structure; in actual production and use, pulleys or similar structures can be added to both ends to further reduce collisions and friction.

[0045] Furthermore, it also includes a thrust bearing 10, which is disposed on the sliding block 9 and the transmission disk 3, with one end disposed on the transmission disk 3 and the other end used to abut against the sliding block 9.

[0046] In this embodiment, one end of the thrust bearing 10 is set on the transmission disk 3, and the other end abuts against the sliding block 9. When the swing block 8 pushes the sliding block 9 to slide, the thrust is transmitted to the transmission disk 3 through the intermediate of the thrust bearing 10, which can reduce the impact of collisions on the transmission disk 3 when it rotates.

[0047] Furthermore, it also includes a first elastic element 11, one end of which acts on the swing block 8 and the other end of which acts on the rotating disk 7, providing a force for the swing block 8 to slide toward the center of the rotating disk 7. A second elastic element 12, one end of which acts on the transmission disk 3 and the other end of which acts on the rotating frame 2, provides a force for the transmission disk 3 to move closer to the swing block 8.

[0048] In this embodiment, the first elastic element 11 is disposed inside the rotating disk 7. When the cable is conveyed at an accelerated speed, the swing block 8 is thrown out. After the speed returns to normal, the first elastic element 11 pulls the thrown block 8 back into the rotating disk 7. At the same time, the first elastic element 11 constrains the swing block 8, so that the extension length of the swing block 8 is different when the rotation speed of the rotating disk 7 is different. This allows the transmission disk 3 to adjust the sliding distance according to the cable conveying speed to achieve the speed difference in transmission to the rotating frame 2. After the swing block 8 retracts, the second elastic element 12 resets the transmission disk 3, so that the rotating frame 2 returns to the rotation speed under normal working conditions.

[0049] Furthermore, the rotating frame 2 also has a belt reel section 202, which is arranged perpendicularly to the rotating shaft of the rotating frame 2, and there are several belt reel sections 202; it also includes a belt guide 13, which is arranged on the rotating frame 2 and has a belt guide hole 1301 for guiding the mica belt after it passes through the belt guide hole 1301.

[0050] In this embodiment, the rotating frame 2 has a winding section 202, which can be provided in multiple ways to allow multiple mica tape rolls to work simultaneously, thus avoiding gaps in the cable. It also includes a guide belt member 13 with angled guide holes 1301. The mica tape passes through the guide holes 1301 to form the angle required to wrap around the mica tape. This simple structure achieves the effect of wrapping the cable with mica tape at a suitable angle.

[0051] Furthermore, it also includes a support frame 14, which is mounted on the body 1 and located on one side of the rotating frame 2. The support frame 14 has a second wire passage hole 1401, which is coaxially arranged with the first wire passage hole 101. The turntable 15 is rotatably mounted on the support frame 14. One end of the fixing member 16 is mounted on the guide belt member 13 or the rotating frame 2, and the other end is mounted on the turntable 15.

[0052] In this embodiment, considering that the rotating frame 2 is an extended structure with a long extension length, it may be damaged or even affect safety if it is not fixed. Therefore, this solution also includes a support frame 14, on which a turntable 15 is rotatably mounted. A fixing member 16 is used to connect the turntable 15 and one end of the rotating frame 2, so that both ends of the rotating frame 2 are fixed to a certain extent, thus achieving stable rotation of the rotating frame 2. This makes the cable more stable during the winding of the mica tape and also prevents the occurrence of malfunctions during the rotation of the rotating frame 2.

[0053] Furthermore, the rotating frame 2 has a keyway 203, and the transmission disk 3 has a sliding part 302, which is slidably disposed in the keyway 203.

[0054] In this embodiment, the rotating frame 2 is provided with a keyway 203, and the transmission disk 3 is provided with a sliding part 302. By using the cooperation of the keyway 203 and the sliding part 302, the transmission disk 3 can slide smoothly while rotating on the rotating frame 2, preventing technical problems such as the inability to transmit normally caused by gaps between the transmission disk 3 and the rotating frame 2 after a long period of rotation and sliding.

[0055] Furthermore, the transmission wheel 6 has an arc-shaped groove 601, which has the same curvature as the cable, and the transmission wheel 6 has several of these grooves.

[0056] In this embodiment, considering that the linear feed of the cable is converted into the rotation of the transmission wheel 6 by the frictional contact between the cables, and that multiple sets of transmission wheels 6 can also center the cable and ensure smooth transport, this solution provides an arc-shaped groove 601 on the transmission wheel 6, and the arc-shaped groove 601 has the same curvature as the cable, which can achieve close contact between the transmission wheel 6 and the cable. While stabilizing and centering the cable, it also achieves good synchronization of the linear speed of the cable and the transmission wheel 6.

[0057] Furthermore, the guide belt 13 is rhomboid or rectangular.

[0058] In this embodiment, the guide belt member 13 is set as a rhombus or rectangle, the guide belt hole 1301 is set on the long side of the guide belt member 13, and the fixing member 16 is set on the outside of the guide belt hole 1301, which can provide more support position and can set or adjust the position of various guide belt holes 1301 according to the actual use.

[0059] Furthermore, it also includes a table 17, which has a mounting cavity 1701, and the drive wheel 6 is located in the mounting cavity 1701.

[0060] In this embodiment, considering that the contact between the transmission wheel 6 and the cable needs to maintain a relatively stable working environment, this solution provides a platform 17, in which the transmission wheel 6 is placed in the mounting cavity 1701 of the platform 17, so that the overall device can obtain a more stable working condition, making the structure more reasonable and reducing the difficulty of maintenance of the transmission wheel 6.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
