Abstract
Description
Technical Field
[0001] The invention relates to the technical field of cable wrapping, in particular to a wrapping device for a semi-tangent wrapping machine. Background Art
[0002] In the field of wire and cable production, the half-cut wrapping machine is a key equipment that wraps wrapping materials such as insulating tape and shielding tape in a spiral manner around the cable core to achieve cable insulation layer construction, shielding protection or structural enhancement. Different from the full-cut wrapping machine's complete cutting process of the wrapping tape, the half-cut wrapping machine adopts partial cutting technology, that is, only one side of the wrapping tape is partially cut during the wrapping process, so that the wrapping tape can complete the spiral winding while maintaining a partial connection. This process characteristic causes the wrapping tape to withstand complex dynamic stresses during movement: on the one hand, the wrapping tape needs to realize spiral trajectory movement with the high-speed rotation of the wrapping device, and frequent changes in direction cause it to produce periodic bending strain; on the other hand, the partial cutting of the wrapping tape by the blade in the half-cut process will introduce instantaneous tensile stress. Coupled with the friction between the wrapping tape and the cable surface, the risk of fatigue damage to the material is further aggravated, making the comprehensive strain force on the wrapping tape significantly higher than that of the traditional full-cut wrapping process.
[0003] However, the wrapping mechanism of existing half-cut wrapping machines is susceptible to external vibration interference during operation, such as mechanical vibration from the equipment's transmission system and low-frequency vibrations in the workshop environment. To ensure a tight, gapless overlap between the wrapping tape and the cable surface, a high pulling tension is typically applied to the cable to maintain the material's position during the wrapping process. However, under high tension, the dynamic stiffness matching between the cable and the wrapping mechanism deteriorates. When external vibrations cause the wrapping mechanism to shift or change position, the tension balance between the cable and the wrapping tape is disrupted, easily leading to high-frequency, minute relative displacements. This relative displacement can create transient impact loads at stress concentration areas, such as the wrapping tape cuts and overlap edges. This is particularly true for brittle wrapping materials such as mica sheets and ceramic fiber tapes, which have weak tensile and impact resistance and are prone to fracture and failure. Reducing the cable pulling tension to alleviate the tape breakage problem can cause the cable to sag and shift during the wrapping process, resulting in defects such as excessive gaps between the wrapping layers and misaligned overlaps, seriously impacting the cable's insulation performance and structural reliability.
[0004] Based on the above problems, those skilled in the art have proposed a wrapping device for a semi-tangent wrapping machine. Summary of the Invention

[0016] The present invention has the following technical points and beneficial effects:
[0017] 1. The magnetorheological fluid can circulate in the first reservoir sleeve and the reservoir assembly. Through the circulation, the magnetorheological fluid can continuously remove the heat generated by the support seat during operation, reducing the thermal fatigue of the components. At the same time, its good lubrication and damping adjustment effects can also reduce the impact and friction between components, thereby extending the service life of the equipment and related components.
[0018] 2. While the magnetorheological fluid is circulating, the speed monitoring component can monitor the displacement stroke of the monitoring plate, and then feed the displacement stroke back to the control unit inside the control base. The control unit inside the control base calculates the relevant flow velocity of the magnetorheological fluid in the T-shaped tube based on the displacement stroke fed back by the displacement sensor, and then determines the specific speed of the magnetorheological anti-vibration wrapping mechanism based on the flow velocity, and adjusts the active end stroke of the tension adjustment electric cylinder according to the speed, thereby controlling the transmission tension of the cable.
[0019] 3. When the rotating parts in the magneto-variable anti-vibration wrapping mechanism vibrate relative to the first liquid storage sleeve, the magnetic field generator generates a magnetic field, and the viscosity and yield stress of the magneto-rheological fluid increase, thereby enabling the magneto-rheological fluid stored in the liquid storage assembly and the first liquid storage sleeve to generate a greater damping force, thereby effectively dissipating the vibration energy and achieving vibration control.
[0020] 4. When the rotating parts in the magneto-variable anti-vibration wrapping mechanism vibrate relative to the first liquid storage sleeve, the viscosity and yield stress of the magneto-rheological fluid increase, causing the displacement stroke of the spring plate to directly decrease at the same speed of the magneto-variable anti-vibration wrapping mechanism. Therefore, it will control the adaptive tension roller to reduce the cable tension, avoid vibration causing the cable to be subjected to additional alternating stress, extend the service life of the cable, and ensure the stability of its electrical and mechanical properties.
[0021] 5. When the amplitude and frequency generated by the rotating parts in the magnetic variable anti-vibration wrapping mechanism reach a certain value, the magnetic field strength generated by the magnetic field generator causes the magnetorheological fluid to change into a solid-like form, and the driving ring is forced to move backward. When the driving ring moves backward, it drives the driving rod to move upward, and then uses the driving T-rod to pull the connecting rod piece to drive the two binding rollers close to each other, so that the cable is clamped inside, and the clamped cable section is driven for wrapping. Using this binding method, the cable and the magnetic variable anti-vibration wrapping mechanism can maintain synchronous vibration, which effectively avoids the relative displacement of the cable and the magnetic variable anti-vibration wrapping mechanism caused by vibration, pulling the wrapping tape.

[0037] like Figure 7As shown, the conductor binding assembly 912 includes four fixing frames 9121, which are respectively fixed on the side walls of the front connecting plate 981 and the rear connecting plate 983 close to each other, and the two fixing frames 9121 installed at the same position are symmetrically distributed, and each fixing frame 9121 is connected to a sliding bracket 9122 with limited sliding, and the outside of the sliding bracket 9122 is fixedly connected to a roller frame 9123, and the inside of the roller frame 9123 is rotatably connected to a binding roller 9124, and an external bracket 9126 is fixedly connected between the front connecting plate 981 and the rear connecting plate 983, and the bottom of the external bracket 9126 is connected to a driving rod 9125 through a spring.

By using this binding method, the cable and the magnetic variable anti-vibration wrapping mechanism 9 can maintain synchronous vibration.
[0038] like Figure 9 As shown, the wrapping assembly 99 includes a central guide plate 991, and main brackets 992 are installed on both sides of the front side wall of the central guide plate 991. A sub-bracket 993 is installed on the side wall where the two main brackets 992 are close to each other. The two groups of sub-brackets 993 are distributed symmetrically in the center, and a spring roller 994 is installed at one end of the sub-bracket 993, and a guide roller 995 is installed at the other end of the sub-bracket 993.
[0039] Example 2, as Figure 7 and Figure 8As shown, this embodiment provides another technical solution based on the first embodiment. The liquid storage component 910 includes a second liquid storage sleeve 9101, and the second liquid storage sleeve 9101 is internally rotatably connected to a circulating fan blade 9102. The middle position of the front side wall of the rear connecting plate 983 is fixedly connected to a card plate placement ring 984. The card plate placement ring 984 is provided with a plurality of placement grooves 985 distributed in a circular array. The interior of each placement groove 985 is connected to a spring card plate 9104 through a spring. The inner wall of the circulating fan blade 9102 is provided with a card groove 9103 that fits with the spring card plate 9104. The interior of the rear connecting plate 983 is fixed with a card plate placement ring 984. A return spring 913 is fixedly connected at the center, and the other end of the return spring 913 is fixedly connected to a drive ring 911. The edges of the front and rear side walls of the drive ring 911 are provided with rounded corners. The rounded corners at the front side of the drive ring 911 fit together with the inner wall of the spring clamp 9104, and the rounded corners at the outer side of the drive ring 911 fit together with the drive rod 9125. The rear side wall of the second liquid storage sleeve 9101 is connected to a circulation pipe 94, and the other end of the circulation pipe 94 is connected to the rear side wall of the first liquid storage sleeve 91. The front side wall of the second liquid storage sleeve 9101 is connected to a return pipe 93, and the other end of the return pipe 93 is interconnected with the first liquid storage sleeve 91.
[0040] Such as Figure 6 and Figure 8 As shown, a reset spring 913 is fixedly connected to the inner center of the rear connecting plate 983, and the other end of the reset spring 913 is fixedly connected to a driving ring 911.

Magnetorheological fluid is stored in the second liquid storage sleeve 9101, the first liquid storage sleeve 91, the circulation pipe 94, the return pipe 93 and the T-shaped tube 971.

It can detect tiny vibrations and measure the acceleration signal of shaft vibration, thereby reflecting the vibration state of the shaft. The magnetic field generator can be selected as a solenoid magnetic field generator. When current passes through, a uniform magnetic field will be generated inside the solenoid. When the amplitude and frequency generated by the rotating parts in the magneto-variable anti-vibration wrapping mechanism 9 reach a certain value, the magnetic field intensity generated by the magnetic field generator prompts the magnetorheological fluid to become a solid-state form. It should be noted that the magnetorheological fluid can change its viscosity and yield stress according to the magnetic field, and the specific correlation coefficient can be obtained by adjusting the ratio of magnetic particles in the magnetorheological fluid according to actual needs and through a limited number of experiments.
[0041] Example 3, as Figure 1 、 Figure 2 、 Figure 5 and Figure 10 As shown, this embodiment provides another technical solution based on the first and second embodiments. A speed monitoring component 97 is provided in the middle position of the return pipe 93. The speed monitoring component 97 includes a T-shaped tube 971. The top front inner wall of the T-shaped tube 971 is connected to a spring plate 972 through a yellow. The front side wall of the spring plate 972 is fixedly connected to a Z-shaped rod 973. The other end of the Z-shaped rod 973 passes through the outer wall of the T-shaped tube 971 and is connected to a monitoring plate 974. The outer wall of the T-shaped tube 971 and the outer side of the monitoring plate 974 are fixedly connected to a monitoring tube 975. A displacement sensor 976 is installed at the inner end of the monitoring tube 975 on the outer side. The adaptive tension roller 6 includes a fixed plate 61. Both ends of the right side wall of the fixed plate 61 are installed with suspension brackets 62. The top of the suspension bracket 62 is installed with a tension adjustment electric cylinder 63. The movable end of the tension adjustment electric cylinder 63 is installed with a suspension tail 64 A tension adjustment roller 65 is installed at the bottom of the hanging tail drag 64. When the wrapping speed is fast, in order to enable the cable to be wrapped according to the prescribed path and shape, a greater tension is required to overcome the inertia of the cable, so that it can quickly change the direction of movement and be tightly wound on the core wire. When the wrapping speed is slow, the inertia of the cable is small, and a smaller tension can control the movement of the cable. Moreover, a lower tension can prevent the cable from being damaged due to excessive stretching. It is also beneficial to ensure the uniformity and stability of the wrapping. The wrapping speed is positively correlated with the conveying speed of the cable. Therefore, when the wrapping speed is slow, the conveying speed of the cable is also slow. At this time, the rotation speed of the circulating fan blade 9102 in the second liquid storage sleeve 9101 is also slow, so the circulation speed of the magnetorheological fluid is slow. At this time, the displacement stroke of the spring plate 972 is short, and when the wrapping speed is fast, the circulation speed of the magnetorheological fluid is fast, and the displacement stroke of the spring plate 972 is long.
[0042] Working principle: The wrapping equipment uses an unwinder 3 to place the cable to be wrapped, and a reel 4 is used to receive the wrapped cable. At the same time, the first tension roller group 5, the adaptive tension roller 6, and the second tension roller group 7 jointly provide tension for the cable transportation, and the magnetic variable anti-vibration wrapping mechanism 9 can realize the rapid wrapping of the cable, wherein the magnetic variable anti-vibration wrapping mechanism 9 is driven by a reduction motor 8, and the two wrapping tapes are wound in the spring roller 994, and are guided by the guide roller 995 to make the wrapping fit on the outside of the cable. When the magnetic variable anti-vibration wrapping mechanism 9 rotates rapidly as a whole, the wrapping tape is continuously wound on the outside of the cable. At this time, the magnetic field generator mounted on the outside of the magnetic variable anti-vibration wrapping mechanism 9 does not work, so the magnetorheological fluid stored in the magnetic variable anti-vibration wrapping mechanism 9 becomes a low-viscosity fluid state, and When the variable anti-vibration wrapping mechanism 9 rotates, the spring clamp 9104 located inside the clamp placement ring 984 is clamped in the clamping groove 9103, so the circulating fan blade 9102 is driven to rotate together. Therefore, driven by the circulating fan blade 9102, the magnetorheological fluid will be drawn from the first liquid storage sleeve 91 through the circulation pipe 94 into the liquid storage component 910, and the magnetorheological fluid in the liquid storage component 910 is discharged into the first liquid storage sleeve 91 through the return pipe 93, thereby realizing the circulation of the magnetorheological fluid in the first liquid storage sleeve 91 and the liquid storage component 910. Through the circulating flow, the magnetorheological fluid can continuously take away the heat generated by the support seat during operation, reducing the thermal fatigue of the components. At the same time, its good lubrication and damping adjustment function can also reduce the impact and friction between components, thereby extending the service life of the equipment and related components.
[0043] While the magnetorheological fluid circulates, the speed monitoring component 97 can monitor the flow rate of the magnetorheological fluid, thereby realizing the tension adjustment of the cable. When the magnetorheological fluid flows into the T-shaped tube 971, it will push the spring plate 972 to move backward, and then drive the monitoring plate 974 to move backward together through the Z-shaped rod 973. The displacement sensor 976 can monitor the displacement stroke of the monitoring plate 974, and then feed back the displacement stroke to the control unit inside the control base 1. The control unit inside the control base 1 calculates the relevant flow rate of the magnetorheological fluid in the T-shaped tube 971 based on the displacement stroke fed back by the displacement sensor 976, and then determines the specific speed of the magnetic variable anti-vibration wrapping mechanism 9 based on the flow rate, and adjusts the movable end stroke of the tension adjustment electric cylinder 63 according to the speed, thereby controlling the transmission tension of the cable.
[0044] It should be noted that when the wrapping speed is fast, in order to enable the cable to be wrapped according to the prescribed path and shape, greater tension is required to overcome the inertia of the cable, so that it can quickly change the direction of movement and be tightly wound around the core wire. When the wrapping speed is slow, the inertia of the cable is small, and smaller tension can control the movement of the cable. Moreover, lower tension can prevent the cable from being damaged due to excessive stretching. It is also beneficial to ensure the uniformity and stability of the wrapping. The wrapping speed is positively correlated with the conveying speed of the cable. Therefore, when the wrapping speed is slow, the conveying speed of the cable is also slow. At this time, the rotation speed of the circulating fan blade 9102 in the second liquid storage sleeve 9101 is also slow, so the circulation speed of the magnetorheological fluid is slow, and the displacement stroke of the spring plate 972 is short. When the wrapping speed is fast, the circulation speed of the magnetorheological fluid is fast, and the displacement stroke of the spring plate 972 is longer.
[0045] When the rotating components within the magneto-variable anti-vibration wrapping mechanism 9 vibrate relative to the first liquid storage sleeve 91, two mutually perpendicular vibration detection sensors 92 on the first liquid storage sleeve 91 can monitor the amplitude and frequency of the rotating components of the magneto-variable anti-vibration wrapping mechanism 9 and adjust the magnetic field size of the magnetic field generator according to the amplitude and frequency. The amplitude and frequency are positively correlated with the magnetic field generated by the magnetic field generator. Therefore, when the amplitude and frequency are large, the magnetic field generated by the magnetic field generator is also large. At this time, the viscosity and yield stress of the magneto-rheological fluid increase, thereby enabling the magneto-rheological fluid stored in the liquid storage assembly 910 and the first liquid storage sleeve 91 to generate a greater damping force, thereby effectively dissipating vibration energy and achieving vibration control. At the same time, as the viscosity and yield stress of the magneto-rheological fluid increase, the displacement stroke of the spring plate 972 directly decreases at the same rotation speed of the magneto-variable anti-vibration wrapping mechanism 9. Therefore, it controls the adaptive tension roller 6 to reduce the cable tension, preventing the cable from being subjected to additional alternating stress due to vibration, extending the service life of the cable, and ensuring the stability of its electrical and mechanical properties.
[0046] When the amplitude and frequency generated by the rotating parts in the magnetic variable anti-vibration wrapping mechanism 9 reach a certain value, the magnetic field strength generated by the magnetic field generator causes the magnetorheological fluid to become a solid-state form. At this time, the circulating fan blades 9102 cannot rotate in the second liquid storage sleeve 9101, and the rotation of the card plate placement ring 984 causes the spring card plate 9104 to be squeezed out of the card slot 9103, thereby causing the inner side of the spring card plate 9104 to drive the drive ring 911 to move backward, and when the drive ring 911 moves backward, it will drive the drive rod 9125 to move upward, and then use the driving T-bar 9128 to pull the connecting rod piece 9127 to drive the two binding rollers 9124 to move closer to each other, so that the cable is The clamped cable section is driven for wrapping, and this binding method can make the cable and the magnetic variable anti-vibration wrapping mechanism 9 maintain synchronous vibration, which effectively avoids the relative displacement of the cable and the magnetic variable anti-vibration wrapping mechanism 9 caused by vibration, pulling the wrapping tape, causing the wrapping tape to break and the wrapping work to be forced to stop. At the same time, since the magnetorheological fluid is in a solid-state form, the spring plate 972 cannot move relative to each other, so the tension adjustment electric cylinder 63 will mobilize the tension adjustment roller 65 to rise to the top. At this time, the cable tension is at the lowest value, which can avoid the cable breakage caused by the binding of the magnetic variable anti-vibration wrapping mechanism 9 to the cable while ensuring the wrapping and conveying work.
