Description

Technical Field

[0001] The present invention relates to the technical field of special equipment for cable manufacturing, and in particular to a preparation device and a preparation method for a high-strength steel-plastic composite tape. Background Art

[0002] Steel-plastic composite tape is a widely used armoring material in optical cable production. Its primary functions include signal shielding, enhancing the mechanical strength of the cable, improving corrosion resistance, and extending the service life of the cable. Steel-plastic composite tape consists of a steel tape coated with a plastic film, and its performance directly impacts the quality and performance of the optical cable. Therefore, toughness testing is an essential step in the production process. Only after passing the toughness test can the tape be released from the factory. However, research has revealed that there is currently no market-proven equipment specifically designed for toughness testing during the production of steel-plastic composite tapes.

[0003] Traditional testing methods often require independent testing steps to evaluate the deformation resistance and durability of steel-plastic composite tapes after they are prepared. This method has significant defects: on the one hand, due to the separation of testing and preparation, it is impossible to monitor product quality in real time during the preparation process, resulting in waste of resources and increased production costs when unqualified products are found after preparation; on the other hand, the lack of dedicated testing equipment for the characteristics of steel-plastic composite tapes may lead to inaccurate test results, making it difficult to fully reflect the actual performance of the steel-plastic composite tapes.

[0004] Based on the above analysis, it can be seen that the existing technology is deficient in the lack of integrated, precise toughness testing equipment for steel-plastic composite tapes, which cannot meet the needs of real-time product quality monitoring and improved detection accuracy. This deficiency leads to the high incidence of defective steel-plastic composite tapes after production, which not only affects the overall quality of the optical cable but also has a negative impact on production efficiency and economic benefits. Therefore, there is an urgent need to develop a cable manufacturing device specifically designed for toughness testing during the production of steel-plastic composite tapes to address these issues and significantly improve product quality and production efficiency.

[0023] First, the device utilizes a flexible bending mechanism, combined with a precise propulsion mechanism, to precisely bend the high-strength steel-plastic composite strip in multiple directions. An internal airbag assembly generates localized protrusions, exerting an appropriate resistance force on the surface of the high-strength steel-plastic composite strip. This design effectively simulates the bending and stress conditions that the steel-plastic composite strip may encounter during actual use, thereby testing its toughness and deformation resistance, ensuring product reliability and durability.

[0025] Furthermore, the present invention utilizes the airbag design, combined with the interaction between the plastic and elastic bladders, to ensure that during the bending process of the steel-plastic composite strip, the airbag automatically adjusts its expansion force according to the bending deformation, thereby applying a uniform and controllable force to the surface of the steel-plastic composite strip.

[0026] In addition, the device of the present invention has a rational structure and integrates multiple high-precision transmission and propulsion mechanisms, such as cylinders and push rollers. Combined with the design of the elastic moving mechanism and the swinging vertical slot, the adaptability and stability of the device during operation are enhanced. Whether during the bending process or when the device is moved or adjusted, it can ensure that the various components of the device are closely matched, avoiding damage to the device or operational failures caused by uncoordinated component movement.

[0036] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0037] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0038] The following is combined with Figures 1 to 5 , through specific embodiments and application scenarios, the preparation equipment and preparation method of a high-strength steel-plastic composite belt provided by this application are described in detail.

[0039] A preparation device for high-strength steel-plastic composite belt, such as Figure 1 、 Figure 2 as well as Figure 3 As shown, the device includes a workbench 1, a flexible bending mechanism 2 and a pushing mechanism 5; wherein, the workbench 1 is installed at the tail end of the high-strength steel-plastic composite belt after it is produced, so that after the high-strength steel-plastic composite belt is produced, the high-strength steel-plastic composite belt can be pushed into the workbench 1.

[0040] Exemplarily, the flexible bending mechanism 2 includes an external bending component 3 and an internal extrusion component 4. The external bending component 3 is arranged on the workbench 1, and two groups of external bending components 3 are arranged in parallel above and below. A through channel 11 is formed between the two groups of bending components for the high-strength steel-plastic composite belt to pass horizontally, and the width and thickness of the through channel 11 are adapted to the width and thickness of the high-strength steel-plastic composite belt. The internal extrusion component 4 is arranged in the external bending component 3.

[0041] Exemplarily, the pushing mechanism 5 includes an upper pushing component 6 and a lower pushing component 7. The upper pushing component 6 is arranged horizontally on the workbench 1 and above the flexible bending mechanism 2. The lower pushing component 7 is arranged horizontally on the workbench 1 and below the flexible bending mechanism 2. The upper pushing component 6 and the lower pushing component 7 are arranged horizontally in sequence in the vertical direction. The upper pushing component 6 and the lower pushing component 7 can generate a vertical thrust on the external bending component 3, so that the external bending component 3 is bent at the corresponding pushing position. When the component 3 generates a vertical downward thrust to make the corresponding pushing portion of the external bending component 3 bend downward, the internal extrusion component 4 will generate a local bulge near the corresponding pushing portion to generate a resistance force acting on the surface of the high-strength steel-plastic composite belt in the through channel 11; when the lower pushing component 7 generates a vertical upward thrust on the external bending component 3 to make the corresponding pushing portion of the external bending component 3 bend upward, the internal extrusion component 4 will also generate a local bulge near the corresponding pushing portion to generate a resistance force acting on the surface of the high-strength steel-plastic composite belt in the through channel 11.

[0042] After being set up in this way, through the vertical thrust of the external bending component 3, combined with the local protrusion design of the internal extrusion component, the device can generate a stable resistance force acting on the surface of the steel-plastic composite belt, accurately simulating the pressure and stretching effects that the steel-plastic composite belt may encounter under actual working conditions. Since the structure of the steel-plastic composite belt includes a composite material of steel belt and plastic film, its toughness and bending performance are determined by the synergistic effect of the two. Therefore, the device of the present invention can comprehensively evaluate its anti-deformation ability and durability by applying forces in different directions to the composite structure. In particular, during the detection process, the local protrusion generated by the internal extrusion component 4 when it is close to the bending part can ensure that the surface of the steel-plastic composite belt is not excessively damaged while making a comprehensive assessment of its toughness. Through this process, the deformation characteristics of the steel-plastic composite belt after being subjected to bending stress can be effectively judged to ensure that it meets the required toughness standards.

[0043] Secondly, the design of the pushing mechanism 5 enhances the device's adjustability and precision. The arrangement of the upper pushing assembly 6 and the lower pushing assembly 7 allows for fine-tuning of the bending force in different directions, thereby controlling the thrust of the external bending assembly 3 and further enhancing precise control of the bending process. This design not only enables localized testing of different areas of the steel-plastic composite strip but also simulates a variety of different bending stress fields, further enhancing the comprehensiveness and authenticity of the testing process.

[0044] Furthermore, by applying precise resistance during the bending process, the device enables real-time quality control of steel-plastic composite strips on the production line. Compared to traditional post-production testing methods, the device of the present invention can perform real-time toughness testing at the end of the finished steel-plastic composite strip, avoiding the waste of resources and production costs caused by the discovery of defective products later. This not only improves production efficiency but also ensures that the steel-plastic composite strips meet standard toughness requirements before leaving the factory, reducing the defective product rate during the production process.

[0045] To sum up, the high-strength steel-plastic composite belt preparation equipment of the present invention, by virtue of its innovative combination of flexible bending mechanism 2 and pushing mechanism 5, realizes accurate detection and real-time monitoring of the toughness and bending performance of the steel-plastic composite belt, effectively improves the quality control level of the production process, and ensures that the steel-plastic composite belt products shipped from the factory can meet the use requirements of high toughness and high strength.

[0046] In some embodiments, Figure 3 、 Figure 4 As shown, the external bending assembly 3 includes an elastic membrane 31 and bending tube segments 32. Multiple bending tube segments 32 are axially connected and hinged between adjacent bending tube segments 32. The elastic membrane 31 wraps between the multiple bending tube segments 32. When the upper push assembly 6 and the lower push assembly 7 are activated, they apply a thrust between adjacent bending tube segments 32 to cause the adjacent bending tube segments 32 to bend. For example, the elastic membrane 31 is made of polyurethane film, which has high elasticity, wear resistance, water resistance, oil resistance, good transparency, and is suitable for long-term use.

[0047] This arrangement, with its axial connection and hinged arrangement, allows the individual bending segments 32 to rotate relatively freely, thereby evenly distributing mechanical stress when thrust is applied. This structural design ensures that the external bending assembly 3 can adaptively adapt to the varying widths and thicknesses of the high-strength steel-plastic composite tape as it passes through, avoiding rigidity issues associated with fixed bending segments 32.

[0048] The sheathing effect of the elastic membrane 31 allows the bending tube segments 32 to maintain a certain degree of flexibility when pushed, preventing local damage that could result from direct contact with the steel-plastic composite strip surface. The membrane's elastic properties further regulate the distribution of thrust, providing a more uniform bending force and reducing damage to the composite strip or uneven bending caused by localized excessive stress. Furthermore, the activation of the upper and lower pusher assemblies 6 and 7 generates precise thrust between adjacent bending tube segments 32, driving them to bend and effectively testing the toughness of the steel-plastic composite strip.

[0049] In some embodiments, combined with Figure 3、 Figure 4 , connecting ears 321 are provided on both sides of the adjacent ends of adjacent bent pipe sections 32, and the adjacent connecting ears 321 are hingedly connected; further, rotation inclined surfaces are provided at the ends of the bent pipe sections 32 and on both sides of the connecting ears 321, and a rotation gap 33 is formed between the two adjacent rotation inclined surfaces, so that the adjacent bent pipe sections 32 can rotate relative to each other at the rotation gap 33.

[0050] On this basis, the setting of the connecting ear piece 321 allows the adjacent bending pipe sections 32 to be connected by a hinge, and can rotate relative to each other when a thrust is applied. This design effectively avoids the rigidity limitation caused by the fixed connection, and realizes the free rotation and coordinated bending of the bending pipe section 32. The design of the rotating bevel allows the adjacent bending pipe sections 32 to rotate relative to each other at a specific rotation gap 33, so that the external bending component 3 can form a smooth and uniform bending process when subjected to a thrust. At the same time, the existence of the rotation gap 33 ensures that the bending pipe sections 32 can be fine-tuned according to actual needs, avoiding uneven bending caused by the inability of adjacent pipe sections to adapt to mechanical changes. Through this design, the distribution of bending force can be controlled more accurately, reducing the risk of uneven pressure or damage to the surface of the steel-plastic composite belt, and ensuring that the toughness detection of the steel-plastic composite belt is more accurate and reliable. Therefore, the design of the present invention further improves the reliability of the equipment and the quality control capabilities during the production of the steel-plastic composite belt.

[0051] In some embodiments, combined with Figure 3 、 Figure 4 The upper pushing assembly 6 includes a first cylinder 61 and a first pushing roller 62, the piston rod of the first cylinder 61 extends vertically downward, and the first pushing roller 62 is arranged at the end of the piston rod of the first cylinder 61; exemplarily, the lower pushing assembly 7 includes a second cylinder 71 and a second pushing roller 72, the piston rod of the second cylinder 71 extends vertically upward, and the second pushing roller 72 is arranged at the end of the piston rod of the second cylinder 71, wherein the first pushing roller 62 and the second pushing roller 72 are both opposite to the rotating gap 33 in the vertical direction, and under the pushing action of the first pushing roller 62 or the second pushing roller 72, the adjacent bent pipe sections 32 bend downward or upward.

[0052] In this way, the first cylinder 61 and the second cylinder 71 can generate a strong pushing force through the vertical expansion and contraction of their piston rods, ensuring that the pushing rollers apply a uniform thrust to the bent pipe section 32. The first pushing roller 62 and the second pushing roller 72 are respectively located at the ends of the upper pushing assembly 6 and the lower pushing assembly 7, and are aligned with the rotating gap 33. This alignment allows the pushing force of the pushing rollers to be precisely applied to the bent pipe section 32, ensuring a uniform distribution of mechanical stress during the bending process and avoiding excessive or insufficient local stress.

[0053] Through the coordination of the upper and lower pusher assemblies 6 and 7, the equipment achieves precise, bidirectional control of the bending tube segments 32, both vertically and horizontally. Specifically, driven by the first and second pusher rollers 62 and 72, adjacent bending tube segments 32 can bend downward or upward at the rotational gaps 33, effectively simulating the deformation properties of the steel-plastic composite strip under different conditions. This design not only enhances flexibility during the bending process but also allows for adjustment of the bending angle and force as needed, enabling precise testing of the steel-plastic composite strip's toughness and bending performance, ensuring compliance with production requirements and further enhancing the equipment's detection accuracy and stability.

[0054] It is worth noting that during the operation of the device, when the first cylinder 61 is running, the corresponding second cylinder 71 needs to be closed to ensure that the first push roller 62 and the second push roller 72 will not conflict with each other to a certain extent.

[0055] In some embodiments, Figure 3 、 Figure 4 As shown, the internal extrusion assembly 4 includes an airbag 41, and a first cavity 322 and a second cavity 323 are opened in the bending tube segment 32 along its own axial direction. The first cavity 322 and the second cavity 323 are respectively located on the radial sides of the connecting ear 321. When two adjacent bending tube segments 32 are axially parallel, the first cavity 322 and the second cavity 323 on the two bending tube segments 32 are horizontally opposite.

[0056] Exemplarily, the end openings of the first cavity 322 and the second cavity 323 are both located on the rotating inclined plane, and a portion of one airbag 41 extends from the first cavity 322 through the rotating gap 33 to the adjacent first cavity 322, and a portion of another airbag 41 extends from the second cavity 323 through the rotating gap 33 to the adjacent second cavity 323, wherein, after the first push roller 62 or the second push roller 72 moves in the vertical direction and applies a thrust to the rotating gap 33, the airbag 41 automatically generates a local bulge toward the passage 11 under the action of the extrusion force and bending deformation.

[0057] Building on this foundation, the introduction of an airbag 41 within the internal extrusion assembly 4 further enhances the accuracy and adaptability of testing the toughness and bending properties of the steel-plastic composite strip. This design allows the device to create localized protrusions on the surface of the steel-plastic composite strip through the extrusion force of the airbag 41 during the rotation of the bending tube segment 32, simulating the deformation conditions the steel-plastic composite strip may experience in actual use. This localized protrusion not only facilitates detailed physical testing of the steel-plastic composite strip, but also enables precise measurement of its deformation and stress response during bending.

[0058] Specifically, a first cavity 322 and a second cavity 323 are provided within the bending tube segment 32, and the two are horizontally aligned on adjacent bending tube segments 32. This design allows the airbag 41 to freely transfer gas between two adjacent bending tube segments 32, ensuring that the expansion and compression effects of the airbag 41 can be normally applied to the surface of the steel-plastic composite belt through the local protrusion. Part of the airbag 41 extends from the first cavity 322 through the rotating gap 33 to the adjacent second cavity 323, while another part extends from the second cavity 323 to the adjacent first cavity 322, forming a closed loop structure. This design allows the airbag 41 to adjust its shape in real time during the bending process, generating precise resistance force, thereby detecting and evaluating the toughness of the steel-plastic composite belt.

[0059] Furthermore, when the first or second push roller 62, 72 moves vertically and applies thrust to the rotational gap 33, the airbag 41 automatically expands under the applied force, forming a localized protrusion at the rotational gap 33 of the bent tube segment 32. This localized protrusion not only accurately simulates the deformation process of the steel-plastic composite strip after being subjected to external extrusion, but also effectively generates a localized resistance force, simulating the complex mechanical environment likely to be encountered in actual use, further improving the authenticity and reliability of toughness testing. Through this design, the equipment can dynamically adjust the strength and position of the localized protrusion according to different testing requirements, thereby achieving comprehensive testing of different material properties.

[0060] In some embodiments, Figure 3 、 Figure 4 As shown, a first radial cavity 324 and a second radial cavity 325 are formed on the bent pipe section 32. One end of the first radial cavity 324 is vertically connected to the end of the first cavity 322, and the other end is open and connected through the channel 11. One end of the second radial cavity 325 is vertically connected to the end of the second cavity 323, and the other end is open and connected through the channel 11.

[0061] Exemplarily, the airbag 41 includes a vertically connected plastic sac 411 and an elastic sac 412. The plastic sac 411 is embedded between the two first cavities 322 and the two second cavities 323. The elastic sac 412 is embedded in the first radial cavity 324 and the second radial cavity 325. When the portion of the plastic sac 411 located in the rotating gap 33 is pushed by the first pushing roller 62 or the second pushing roller 72, the plastic sac 411 will push the The force is converted into an expansion force of the elastic bladder 412, so that the elastic bladder 412 expands toward the through-channel 11 at the end away from the plastic bladder 411; when the first pushing roller 62 or the second pushing roller 72 applies a pushing force to cause the adjacent bent tubes to bend relative to each other, the plastic bladder 411 is subjected to a deformation force and bends synchronously, and the deformation force is converted into an expansion force acting on the elastic bladder 412, so that the elastic bladder 412 expands toward the through-channel 11 at the end away from the plastic bladder 411. Exemplarily, a hole is coaxially opened at the position of the elastic membrane 31 corresponding to the port of the first radial channel 324 and the second radial channel 325, so that the elastic bladder 412 can extend through the hole and enter the through-channel 11 when it expands.

[0062] On this basis, the first radial channel 324 and the second radial channel 325 in the bending tube segment 32 are perpendicularly connected to the first channel 322 and the second channel 323, respectively, and are connected to the through-channel 11 through the openings at their ends. This design enables the airbag 41 system to apply force uniformly and precisely during the bending process through the guidance of the channels, ensuring a balanced pressure distribution during testing, thereby effectively simulating the external forces acting in an actual working environment.

[0063] The airbag 41 consists of a plastic bladder 411 and an elastic bladder 412. The plastic bladder 411 is embedded between the first cavity 322 and the second cavity 323, while the elastic bladder 412 is embedded in the radial cavity. The synergistic effect of the plastic bladder 411 and the elastic bladder 412 is the core innovation of this design. When the first push roller 62 or the second push roller 72 applies a pushing force, the plastic bladder 411 is affected by the force and bends and deforms. At this time, the plastic bladder 411 converts the pushing force into the expansion force of the elastic bladder 412, forcing the elastic bladder 412 to expand into the passage 11. The expansion force of the elastic bladder 412 can accurately control and simulate the mechanical response of the steel-plastic composite belt in actual operation.

[0064] At the same time, when the driving force causes the adjacent bending tube section 32 to bend, the plastic bladder 411 will bend synchronously, generating a deformation force. This deformation force will in turn be converted into an expansion force on the elastic bladder 412, causing the elastic bladder 412 to further expand and exert a local resistance force on the surface of the steel-plastic composite belt, thereby achieving accurate testing of the toughness and bending performance of the steel-plastic composite belt. Through the coordinated work of the plastic bladder 411 and the elastic bladder 412, the high-strength steel-plastic composite belt can bend under external force while also being resisted by the local protrusions, achieving the effect of simultaneously testing the deformation resistance and durability of the high-strength steel-plastic composite belt, ensuring the accuracy and consistency of the mechanical response during the testing process.

[0065] In some embodiments, combined with Figure 3 、 Figure 4 as well as Figure 5 Horizontal channels 12 are provided on both side walls of the workbench 1, and the horizontal channels 12 are connected to the through channel 11. The upper and lower sides of the horizontal channel 12 are parallel and connected to each other, and a movable channel 13 is provided. An elastic movable mechanism 8 is provided in the movable channel 13, and the elastic movable mechanism 8 can adaptively move when the flexible bending mechanism 2 bends to adaptively cooperate with the bending of the flexible bending mechanism 2.

[0066] Exemplarily, the elastic moving mechanism 8 includes a spring 81 and a moving block 82. The moving block 82 is slidably disposed within the moving channel 13 and is hingedly connected to the end of the bending tube section 32 at the endmost portion. Furthermore, one end of the spring 81 is connected to the inner end wall of the moving channel 13, and the other end is connected to the moving block 82. The spring 81 always has a tendency to horizontally drive the moving block 82 toward a side away from the flexible bending mechanism 2. Exemplarily, the horizontal channel 12 and the moving channel 13 are connected by a transverse groove. The width of the transverse groove is smaller than the width of both the horizontal channel 12 and the width of the moving channel 13. This ensures that the moving block 82 can stably move within the moving channel 13 and is not easily dropped into the horizontal channel 12.

[0067] Illustratively, a swinging vertical slot 14 is further provided on the side wall of the workbench 1 close to the flexible bending mechanism 2 . The swinging vertical slot 14 is connected to the moving channel 13 and can accommodate the bent pipe section 32 at the end in a bent state.

[0068] With this arrangement, horizontal channel 12 is connected to through channel 11, allowing the device to precisely control the material's path of movement during the bending process of the steel-plastic composite strip. Furthermore, movable channels 13 are provided on both the upper and lower sides of horizontal channel 12, communicating therewith. Within movable channels 13, an elastic movable mechanism 8 is positioned. This design ensures that when the flexible bending mechanism 2 performs a bending operation, the elastic movable mechanism 8 automatically adjusts its position based on deformation during the bending process, allowing the device to adapt to varying bending requirements. This design allows the device to flexibly respond to and effectively coordinate with the movement of the flexible bending mechanism 2 during bending of the steel-plastic composite strip, avoiding material damage or measurement errors caused by uneven bending or uneven force.

[0069] Furthermore, by sliding the movable block 82 within the movable channel 13 and hingedly connected to the end of the bending tube segment 32 at the extreme end, the bending tube segment 32 can be smoothly displaced during the bending process. At the same time, the spring 81 always drives the movable block 82 horizontally toward the side away from the flexible bending mechanism 2. This design ensures that the equipment can smoothly perform fine adjustments when bending the steel-plastic composite strip and effectively avoids the impact of excessive or insufficient force on the bending quality.

[0070] Furthermore, a swinging vertical slot 14 is provided on the side wall of the workbench 1 near the flexible bending mechanism 2, communicating with the movable channel 13. This slot 14 accommodates the bent tube segment 32 at the end of the bending process. This swinging vertical slot 14 allows the bent tube segment 32 to move more freely during the bending process, avoiding operational difficulties caused by space limitations or excessive frictional resistance, further improving the stability and operational flexibility of the equipment.

[0074] At the same time, the internal extrusion assembly 4 is driven to locally extrude the high-strength steel-plastic composite strip in the through channel 11 to test the local toughness of the high-strength steel-plastic composite strip;

[0075] After the test is completed, the high-strength steel-plastic composite belt can be pulled out from the other end of the workbench 1.
