Description

Technical Field

[0001] The invention belongs to the technical field of cable manufacturing, and in particular relates to a steel strip pressing mechanism, an armoring machine and an armoring method for flat cables. Background Art

[0002] Flat cables are widely used in petrochemical industry due to their excellent bending performance and excellent performance in flexible wiring in complex pipeline and equipment layout. However, the petrochemical environment is usually accompanied by extreme conditions such as high temperature, high pressure and humidity, which puts strict requirements on the corrosion resistance of flat cables. Steel tape armored flat cables are an ideal choice for such environments due to their excellent corrosion resistance.

[0003] When performing steel tape armoring, in order to enhance the protection of the cable and reduce the risk of cracks or breaks in the steel tape during the wrapping process, a steel tape with strong rigidity is usually selected. However, a steel tape with too strong rigidity is often difficult to fit tightly to the flat cable during the armoring process. This problem is more prominent in flat cables than in round cables, because the flat shape makes it more difficult for the steel tape to fit tightly when winding.

[0004] A loose fit of the steel tape will directly affect the mechanical strength of the cable. The cable is more susceptible to damage when subjected to external forces such as stretching, bending or squeezing. In addition, armored cables with loose steel tape are more susceptible to corrosion in humid or corrosive environments, further reducing their service life and reliability. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a steel strip pressing mechanism, an armoring machine and an armoring method for a flat cable, so as to solve the technical problem that the steel strip is often difficult to fit tightly to the flat cable during the armoring process.

[0006] One of the present inventions: In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention includes: Mounting plate; A first clamping portion, the first clamping portion includes a first eccentric disk, a first movable plate and a first limiting structure, wherein the first eccentric disk is vertically arranged and rotatably connected to the mounting plate, the middle portion of the first movable plate has an accommodating space for accommodating the first eccentric disk, the first eccentric disk is located in the accommodating space and is movably connected to the first movable plate, a first clamping surface is provided below the first movable plate, the first limiting structure is arranged on the mounting plate, the first limiting structure is used to limit the first movable plate from rotating as the first eccentric disk rotates, and when the first eccentric disk is rotated, the first clamping surface can move up and down along an elliptical trajectory; A second clamping portion, the second clamping portion includes a second eccentric disk, a second movable plate and a second limiting structure, wherein the second eccentric disk is vertically arranged and rotatably connected to the mounting plate, the middle portion of the second movable plate has an accommodating space for accommodating the second eccentric disk, the second eccentric disk is located in the accommodating space and is movably connected to the second movable plate, a second clamping surface is provided above the second movable plate, the second clamping surface is arranged opposite to the first clamping surface, the second limiting structure is arranged on the mounting plate and is used to limit the second movable plate from rotating as the second eccentric disk rotates, and when the second eccentric disk is rotated, the second clamping surface can move up and down along an elliptical trajectory; A driving component is used to drive the first eccentric disk and the second eccentric disk to rotate synchronously in different rotation directions so that the first clamping surface and the second clamping surface can make continuous relative or opposite movements, gradually compress the flat cable during the relative movement of the first clamping surface and the second clamping surface, and gradually loosen the flat cable during the opposite movement of the first clamping surface and the second clamping surface.

[0007] Compared with the prior art, the advantages of the present invention include: (1) The steel belt pressing mechanism for a flat cable provided by the present invention has a small number of mechanical parts, a simple structure, and is easy to maintain.

[0008] (2) The steel belt clamping mechanism for a flat cable provided by the present invention can realize dynamic clamping and release of the external steel belt of the flat cable by rotating the first eccentric disk and the second eccentric disk, thereby reducing the interference with the movement of the flat cable during clamping and reducing the damage to the flat cable.

[0009] (3) The steel belt pressing mechanism for a flat cable provided by the present invention has a first pressing surface and a second pressing surface that are flatly attached to the upper and lower surfaces of the cable during pressing, so that the pressure can be evenly distributed on the surface of the cable, which helps to reduce local deformation or damage of the cable caused by uneven pressure.

[0010] (4) The steel belt clamping mechanism for a flat cable provided by the present invention is designed with a driving component that enables the first eccentric disk and the second eccentric disk to rotate synchronously in different rotation directions. This synchronous control enables the first clamping surface and the second clamping surface to be coordinated during relative or opposite movement, thereby achieving stable clamping and loosening of the external steel belt of the flat cable, which helps to reduce the distortion or misalignment of the flat cable caused by the lack of synchronization between the first clamping surface and the second clamping surface.

[0011] (5) The steel belt pressing mechanism for the flat cable provided by the present invention presses the outer steel belt of the flat cable through the pressing assembly, so that the steel belt can fit tightly with the flat cable, solving the technical problem that the mechanical strength of the flat cable is low due to the loose fitting of the steel belt. In addition, the cable is not easily damaged when subjected to external forces such as stretching, bending or squeezing. In addition, in a humid or corrosive environment, the flat cable with a tightly fitted steel belt is less susceptible to corrosion, further enhancing the service life and reliability.

[0012] (6) The steel belt clamping mechanism for flat cables provided by the present invention can realize continuous clamping and releasing actions, and is easy to operate, stable and reliable. Therefore, it can greatly improve the production efficiency of flat cables during transmission, processing and fixing. At the same time, the stable clamping effect also helps to reduce production interruptions and losses caused by loose or damaged cables.

[0013] (7) Compared with the traditional clamping method, the steel belt clamping mechanism for flat cables provided by the present invention adopts a mechanical structure design to achieve the clamping and releasing functions without the need for additional electrical control components or complex control systems. This not only reduces the manufacturing cost of the equipment, but also reduces energy consumption and maintenance costs.

[0014] Further, the second pressing surface has a groove for accommodating the flat cable, and the groove extends in a horizontal direction and passes through two sides of the second pressing surface; The first pressing surface has a pressing block that cooperates with the groove.

[0015] In the present invention: (1) The groove design on the second pressing surface can accommodate the flat cable more accurately, ensure the stability of the flat cable position during the pressing process, reduce the deviation or distortion of the flat cable during transmission, and improve the accuracy and reliability of the pressing. In addition, the side wall of the groove can also press the side wall of the flat cable during the pressing process of the outer steel belt of the flat cable, thereby achieving more comprehensive pressing.

[0016] (2) The compression block on the first compression surface can cooperate with the groove on the second compression surface to form a double compression effect on the outer steel belt of the flat cable. This design not only improves the compression stability, but also enables the flat cable to be subjected to uniform pressure distribution during the compression process.

[0017] Furthermore, both sides of the groove top in the length direction extend in opposite directions respectively so that the width of the groove top is greater than the width of the groove bottom.

[0018] Furthermore, the second pressing surface has two clamping blocks at the top, the middle parts of the two clamping blocks form the groove, and the two clamping blocks are slidably connected with the pressing surface along the width direction of the groove; The second movable plate is provided with an adjustment component for adjusting the distance between the two clamping blocks, and the width of the groove can be changed by the adjustment component; The pressing block is detachably connected to the first pressing surface, and the pressing block has multiple sizes. When the width of the groove changes, a pressing block that is adapted to the size of the groove is selected.

[0019] In the present invention, two slidable blocks are arranged on the top of the second pressing surface, and an adjustment component is provided to adjust the distance between the blocks, thereby changing the width of the groove. This design enables the pressing mechanism to flexibly adapt to flat cables of different sizes, thereby improving the versatility and applicability of the pressing mechanism.

[0020] The second of the present invention: An armoring machine comprises a bracket, a winding mechanism and the above-mentioned steel belt pressing mechanism; Wherein, the driving component of the steel belt pressing mechanism includes a first gear, a second gear and a driving motor, the first gear is fixedly connected to the eccentric position of the first eccentric disk through a first rotating shaft, the first rotating shaft is rotatably arranged on the mounting frame, the second gear is fixedly connected to the eccentric position of the second eccentric disk through a second rotating shaft, the second rotating shaft is rotatably arranged on the mounting frame, the first gear and the second gear are meshed with each other, the driving motor is installed on the bracket, and the output shaft of the motor is transmission-connected to the first gear or the second gear to drive the first gear and the second gear to rotate synchronously; The winding mechanism includes a gear ring, which is rotatably arranged on a bracket, and a third gear that meshes with the gear ring is rotatably arranged on the bracket, and a suspension component for mounting a steel belt roll is fixedly connected to the gear ring, and the gear ring can be synchronously driven to rotate by rotating the third gear, thereby causing the suspension component to drive the steel belt roll to rotate, and the steel belt is gradually released and wound on the flat cable during the rotation of the steel belt roll; A transmission assembly is provided between the winding mechanism and the driving component, the transmission assembly comprising a worm wheel and a worm, the worm wheel is coaxially fixedly connected to the third gear, one end of the worm is transmission-connected to the worm wheel, and the other end is transmission-connected to the driving motor; The bracket is provided with a channel for the flat cable to pass through, the channel extends along the axis of the gear ring, and two ends of the channel pass through two ends of the gear ring respectively.

[0021] In the present invention, the steel belt winding work and the steel belt pressing work are linked together through a transmission component, which has a high degree of automation and is relatively convenient to use. The steel belt winding work and the steel belt pressing work are linked together through mechanical linkage. Since the mechanical linkage is achieved through physical connection, this will make the transmission process more reliable and reduce the problem of linkage failure caused by electronic component failure or signal interference. At the same time, the mechanical linkage has high stability and is not easily affected by external environment interference, such as electromagnetic interference and temperature changes.

[0022] Furthermore, the suspension component includes a mounting block fixed on the gear, the mounting block is provided with a winding disk that can slide along the diameter direction of the gear ring, the winding disk and the mounting block are detachably connected, a steel belt is wound on the winding disk, and an elastic member is provided between the winding disk and the mounting block, through which the steel belt can be kept in a tensioned state at all times when it is wound around the flat cable.

[0023] In the present invention: (1) By setting the elastic member, the steel belt always maintains a tensioned state during the winding process, avoiding the problem of loosening or knotting of the steel belt. This tensioning effect helps to improve the fit between the steel belt and the flat cable and enhance the armoring effect.

[0024] (2) The setting of the elastic member enables the winding drum to automatically adjust its position when subjected to external force, thereby reducing the risk of equipment damage caused by external force. At the same time, the elastic member also plays a buffering role, extending the service life of the equipment.

[0025] The third invention: An armoring method comprises the following steps: S1. Install the winding drum with the wound steel strip on the mounting block; S2, the end of the flat cable is first pulled through the channel, and then passed through the middle of the first pressing part and the second pressing part, so that the end is connected to the external traction mechanism; S3, pull the steel belt along the diameter direction of the gear ring to move its end to the flat cable, and fix the end of the steel belt and the flat cable together; S3. Start the external traction mechanism and the driving motor. The driving motor drives the gear ring to rotate under the transmission action of the worm, the worm wheel and the third gear. The rotation of the gear ring drives the winding disk to rotate. During the rotation of the winding disk, the steel belt is gradually wound on the flat cable. At the same time, the driving motor drives the first gear and the second gear to rotate arbitrarily to make the first eccentric disk and the second eccentric disk rotate in different rotation directions, so that the first pressing surface and the second pressing surface continuously move relative to or opposite to each other, thereby realizing the compression and loosening of the external steel belt of the flat cable. The synchronous start of the traction mechanism will keep the cable moving, thereby realizing continuous winding and continuous compression of the steel belt.

[0026] Furthermore, before step S2, according to different types of flat cables, the adjusting component is adjusted to change the groove width to adapt to different types of flat cables, and the pressing block adapted to the groove width is replaced at the same time.

[0035] One of the present inventions: See also Figure 1-2 The present invention provides a technical solution: a steel belt clamping mechanism for a flat cable 29, comprising a mounting plate 1, a first clamping portion, a second clamping portion and a driving component.

[0036] The mounting plate 1 serves as the foundation and supporting structure of the entire clamping mechanism and is used to fix and connect the first clamping part and the second clamping part.

[0037] The first clamping portion includes a first eccentric disk 2, a first movable plate 3 and a first limiting structure. Among them, the first eccentric disk 2 is vertically arranged and rotatably connected to the mounting plate 1, and the first eccentric disk 2 can produce an eccentric effect when it rotates. The first movable plate 3 is vertically arranged, and the middle part of the first movable plate 3 has a storage space for accommodating the first eccentric disk 2. The first eccentric disk 2 is located in the storage space and is movably connected to the first movable plate 3. The storage space of the first movable plate 3 allows the first eccentric disk 2 to move inside it. Specifically, the first movable plate 3 is provided with a first through hole that penetrates the first movable plate 3 along the thickness direction, the first eccentric disk 2 is located in the first through hole, and the first eccentric disk 2 and the first movable plate 3 are movably connected through a bearing. A first clamping surface 4 is provided below the first movable plate 3, and the first clamping surface 4 is used to contact the top surface of the flat cable 29 and apply a clamping force. The first limiting structure is arranged on the mounting plate 1, and is used to limit the first movable plate 3 from rotating along with the first eccentric disk 2. When the first eccentric disk 2 is rotated, the first pressing surface 4 can move up and down along an elliptical trajectory.

[0038] Specifically, the first limiting structure includes a first connecting rod 5, which is extended in the horizontal direction. The first connecting rod 5 is provided with a first limiting hole 6 that penetrates the first connecting rod 5 in the vertical direction. The first limiting hole 6 is in the shape of a strip, and the length direction is consistent with the horizontal direction. A first limiting rod 7 is arranged in the first limiting hole 6. The first limiting rod 7 is slidably arranged on the mounting plate 1 in the vertical direction. Two first limiting rings 8 are arranged on the first limiting rod 7. The two first limiting rings 8 are respectively located on the upper and lower sides of the first connecting rod 5, and respectively abut against the upper and lower sides of the first connecting rod 5. When the first movable plate 3 moves, the first limiting hole 6 can only move the first movable plate 3 in the horizontal direction. At the same time, the first limiting rod 7 can only move the first movable plate 3 in the vertical direction, so that the first movable plate 3 is not easy to rotate with the first eccentric disk 2.

[0039] The second clamping part includes a second eccentric disk 9, a second movable plate 10 and a second limiting structure. Among them, the second eccentric disk 9 is vertically arranged and rotatably connected to the mounting plate 1, the second movable plate 10 is vertically arranged, and the middle part of the second movable plate 10 has a storage space for accommodating the second eccentric disk 9, the second eccentric disk 9 is located in the storage space and is movably connected to the second movable plate 10, and the storage space of the second movable plate 10 allows the second eccentric disk 9 to move inside it. Specifically, the second movable plate 10 is provided with a second through hole that penetrates the second movable plate 10 along the thickness direction, the second eccentric disk 9 is located in the second through hole, and the second eccentric disk 9 and the second movable plate 10 are movably connected through a bearing. A second clamping surface 34 is provided above the second movable plate 10, and the second clamping surface 34 is arranged opposite to the first clamping surface 4, and the second clamping surface 34 is used to contact the bottom surface of the flat cable 29 and apply a clamping force. The second limiting structure is disposed on the mounting plate 1 and is used to limit the second movable plate 10 from rotating along with the second eccentric disk 9 . When the second eccentric disk 9 is rotated, the second pressing surface 34 can move up and down along an elliptical trajectory.

[0040] Specifically, the second limiting structure includes a second connecting rod 11, which is extended in the horizontal direction. A second limiting hole 12 is provided on the second connecting rod 11 and passes through the second connecting rod 11 in the vertical direction. The second limiting hole 12 is in the shape of a strip, and the length direction is consistent with the horizontal direction. A second limiting rod 13 is provided in the second limiting hole 12. The second limiting rod 13 is slidably provided on the mounting plate 1 in the vertical direction. Two second limiting rings 14 are provided on the second limiting rod 13. The two second limiting rings 14 are respectively located on the upper and lower sides of the second connecting rod 11, and respectively abut against the upper and lower sides of the second connecting rod 11. When the second movable plate 10 moves, the second limiting hole 12 can only move the second movable plate 10 in the horizontal direction. At the same time, the second limiting rod 13 can only move the second movable plate 10 in the vertical direction, so that the second movable plate 10 is not easy to rotate with the second eccentric disk 9.

[0041] The driving component is used to drive the first eccentric disk 2 and the second eccentric disk 9 to rotate synchronously in different rotation directions so that the first clamping surface 4 and the second clamping surface 34 can make continuous relative or opposite movements, gradually compressing the flat cable 29 during the relative movement of the first clamping surface 4 and the second clamping surface 34, and gradually loosening the flat cable 29 during the opposite movement of the first clamping surface 4 and the second clamping surface 34.

[0042] When the driving component is started, the first eccentric disk 2 and the second eccentric disk 9 start to rotate synchronously in opposite directions. Due to the eccentric design, the first movable plate 3 and the second movable plate 10 move in the vertical direction respectively. The first movable plate 3 moves downward, and at the same time, the second movable plate 10 moves upward, so that the first pressing surface 4 and the second pressing surface 34 gradually approach the flat cable 29. In this process, the first pressing surface 4 and the second pressing surface 34 move downward and upward respectively according to the elliptical trajectory, and gradually apply a pressing force to the flat cable 29.

[0043] As the first eccentric disk 2 and the second eccentric disk 9 continue to rotate, the first movable plate 3 and the second movable plate 10 begin to change their moving directions. The first movable plate 3 moves upward, while the second movable plate 10 moves downward, so that the first pressing surface 4 and the second pressing surface 34 gradually move away from the flat cable 29. In this process, the first pressing surface 4 and the second pressing surface 34 also move up and down along an elliptical trajectory, and gradually release the pressing force on the flat cable 29.

[0044] By continuous rotation of the driving member, the first eccentric disc 2 and the second eccentric disc 9 will continuously change their positions relative to the mounting plate 1 and the movable plate. This will cause the first pressing surface 4 and the second pressing surface 34 to move on a continuous elliptical trajectory and apply periodic pressing and loosening actions to the flat cable 29.

[0045] In this embodiment, the second pressing surface 34 has a groove 15 for accommodating the flat cable 29 , and the groove 15 extends horizontally through both sides of the second pressing surface 34 . The first pressing surface 4 has a pressing block 16 that cooperates with the groove 15 .

[0046] The groove 15 on the second pressing surface 34 is designed to accommodate the flat cable 29 more accurately, ensure the stability of the position of the flat cable 29 during the pressing process, reduce the deviation or distortion of the flat cable 29 during the transmission process, and improve the accuracy and reliability of the pressing. In addition, the side wall of the groove 15 can also press the steel belt on the side wall of the flat cable 29, thereby achieving more comprehensive pressing.

[0047] The compression block 16 on the first compression surface 4 is designed to cooperate with the groove 15 on the second compression surface 34 to form a double compression effect on the outer steel belt of the flat cable 29. This design not only improves the compression stability, but also enables the flat cable 29 to be subjected to uniform pressure distribution during the compression process.

[0048] In this embodiment, the two sides of the top of the groove 15 in the length direction extend in opposite directions respectively so that the width of the top of the groove 15 is larger than the width of the bottom. The flared design in which the width of the top of the groove 15 is larger than the width of the bottom makes it easier for the flat cable 29 to be guided into the groove 15 when pressed. At the same time, the flared design will also reduce the damage to the side of the flat cable 29 caused by the interference of the two sides of the groove 15 with the side of the flat cable 29 when the flat cable 29 enters the groove 15.

[0049] In this embodiment: the second pressing surface 34 has two blocks 17 at the top, the middle of the two blocks 17 form a groove 15, and the two blocks 17 are slidably connected to the pressing surface along the width direction of the groove 15. The second movable plate 10 is provided with an adjustment component for adjusting the distance between the two blocks 17, and the width of the groove 15 can be changed by adjusting the component. By arranging two slidable blocks 17 at the top of the second pressing surface 34 and equipping the adjustment component to adjust the distance between the blocks 17, the width of the groove 15 can be changed. This design enables the pressing mechanism to flexibly adapt to flat cables 29 of different sizes, thereby improving the versatility and applicability of the pressing mechanism.

[0050] The pressing block 16 is detachably connected to the first pressing surface 4, and the pressing block 16 has multiple sizes. When the width of the groove 15 changes, a pressing block 16 that is adapted to the size of the groove 15 is selected. The detachable connection design of the pressing block 16 and the first pressing surface 4 allows the pressing block 16 to be easily replaced as needed. When the width of the groove 15 changes, a pressing block 16 that is adapted to the size of the groove 15 can be selected to improve the pressing effect.

[0051] Specifically, the adjustment assembly includes a screw rod 18 rotatably arranged on the second movable plate 10, the screw rod 18 is composed of two rod parts with different spiral directions, both rod parts are threadedly matched with sliders 19, and the two sliders 19 are respectively fixedly connected to the two clamping blocks 17. By rotating the screw rod 18, the two sliders 19 can move relative to or away from each other, thereby driving the two clamping blocks 17 to move relative to or away from each other.

[0052] The second of the present invention: See also Figure 3-4 , an armoring machine includes a bracket 20, a winding mechanism and the above-mentioned steel belt pressing mechanism.

[0053] Among them, the driving components of the steel belt clamping mechanism include a first gear 21, a second gear 22 and a driving motor 23. The first gear 21 is fixedly connected to the eccentric position of the first eccentric disk 2 through a first rotating shaft, and the first rotating shaft is rotatably set on the mounting frame. The second gear 22 is fixedly connected to the eccentric position of the second eccentric disk 9 through a second rotating shaft, and the second rotating shaft is rotatably set on the mounting frame. The first gear 21 and the second gear 22 are meshed with each other. The driving motor 23 is installed on the bracket 20, and the output shaft of the driving motor 23 is transmission-connected to the first gear 21 or the second gear 22 to drive the first gear 21 and the second gear 22 to rotate synchronously.

[0054] It should be noted that the drive motor 23 is used to drive the first gear 21 and the second gear 22 to rotate synchronously in the following two ways: one is that the drive motor 23 drives the first gear 21 to rotate, and the first gear 21 drives the second gear 22 to rotate; the other is that the drive motor 23 drives the second gear 22 to rotate, and the second gear 22 drives the first gear 21 to rotate. Specifically, the drive motor 23 and the first gear 21 or the second gear 22 can be connected to each other in a sprocket type, a belt type or a synchronous belt type transmission mode.

[0055] The winding mechanism includes a gear ring 24, which is rotatably arranged on the bracket 20, and a third gear 25 meshing with the gear ring 24 is rotatably arranged on the bracket 20, and a suspension component for mounting a steel belt roll 32 is fixedly connected to the gear ring 24. The gear ring 24 can be synchronously driven to rotate by rotating the third gear 25, and then the suspension component drives the steel belt roll 32 to rotate. During the rotation of the steel belt roll 32, the steel belt is gradually released and wound on the flat cable 29; A transmission assembly is provided between the winding mechanism and the driving component, and the transmission assembly includes a worm wheel 26 and a worm 27. The worm wheel 26 is coaxially fixedly connected with the third gear 25. One end of the worm 27 is transmission-connected with the worm wheel 26, and the other end is transmission-connected with the driving motor 23. Specifically, one end of the worm 27 away from the worm wheel 26 is transmission-connected with the output shaft of the driving motor 23 through a coupling. The driving motor 23 drives the worm 27 to rotate, and the rotation of the worm 27 drives the worm wheel 26 to rotate, and the rotation of the worm wheel 26 drives the third gear 25 to rotate, and the rotation of the third gear 25 drives the gear ring 24 to rotate.

[0056] The bracket 20 is provided with a channel 28 for the flat cable 29 to pass through, and the channel 28 extends along the axis of the gear ring 24, and the two ends respectively pass through the two ends of the gear ring 24. The channel 28 is provided to provide a moving channel 28 for the transmission of the flat cable 29, and also has a positioning function, so that the flat cable 29 is always located at the center of the gear ring 24 during transmission.

[0057] The steel belt winding work and the steel belt pressing work are linked together through the transmission component, which has a high degree of automation and is relatively convenient to use. The steel belt winding work and the steel belt pressing work are linked together through mechanical linkage. Since the mechanical linkage is achieved through physical connection, this will make the transmission process more reliable and reduce the problem of linkage failure caused by electronic component failure or signal interference. At the same time, the mechanical linkage has high stability and is not easily affected by external environment interference, such as electromagnetic interference and temperature changes.

[0058] In this embodiment: the suspension component includes a mounting block 30 fixed on the gear. The mounting block 30 is the basis of the suspension component. It is fixedly connected to the gear ring 24 and rotates with the rotation of the gear ring 24. The design of the mounting block 30 needs to consider its strength and stability so that it can bear the weight of the steel belt roll 32 and the force generated during rotation. The mounting block 30 is provided with a winding disk 31 that can slide along the diameter direction of the gear ring 24. The winding disk 31 is detachably connected to the mounting block 30, which is convenient for replacing steel belt rolls 32 of different specifications. The winding disk 31 is wound with a steel belt. An elastic member 33 is provided between the winding disk 31 and the mounting block 30. Through the elastic member 33, when the steel belt is wound on the flat cable 29, the steel belt can always be in a tensioned state. The elastic member 33 can be a spring, elastic rubber, etc., and its selection needs to be carried out according to the material, thickness and winding tension requirements of the steel belt. In this embodiment, the elastic member 33 is a spring, one end of which is hinged to the axis of the winding disk 31 close to the gear ring 24 , and the other end of the spring is hinged to the mounting block 30 after extending outward.

[0059] By setting the elastic member 33, the steel belt always maintains a tensioned state during the winding process, avoiding the problem of loosening or knotting of the steel belt. This tensioning effect helps to improve the fit between the steel belt and the flat cable 29 and enhance the armoring effect. In addition, the setting of the elastic member 33 enables the winding disk 31 to automatically adjust its position when subjected to external force, reducing the risk of equipment damage caused by external force. At the same time, the elastic member 33 also plays a buffering role, extending the service life of the equipment.

[0060] The third invention: An armoring method comprises the following steps: S1, installing the winding drum 31 on which the steel strip has been wound on the mounting block 30; S2, the end of the traction flat cable 29 first passes through the channel 28, and then passes through the middle of the first pressing part and the second pressing part, so that the end is connected to the external traction mechanism; S3, pulling the steel belt along the diameter direction of the gear ring 24, so that its end moves to the flat cable 29, and fixing the end of the steel belt and the flat cable 29 together; S3. Start the external traction mechanism and the drive motor 23. The drive motor 23 drives the gear ring 24 to rotate under the transmission action of the worm 27, the worm wheel 26 and the third gear 25. The rotation of the gear ring 24 drives the winding disk 31 to rotate. During the rotation of the winding disk 31, the steel belt is gradually wound on the flat cable 29. At the same time, the drive motor 23 drives the first gear 21 and the second gear 22 to rotate arbitrarily to make the first eccentric disk 2 and the second eccentric disk 9 rotate in different rotation directions, so that the first clamping surface 4 and the second clamping surface 34 continuously move relative to or opposite to each other, thereby realizing the compression and loosening of the external steel belt of the flat cable 29. The synchronous start of the traction mechanism will keep the cable in motion, thereby realizing continuous winding and continuous compression of the steel belt.

[0061] In this embodiment: before step S2 , according to different models of flat cables 29 , the adjusting assembly is adjusted to change the width of the groove 15 to adapt to different models of flat cables 29 , and the pressing block 16 adapted to the width of the groove 15 is replaced.
