Description

Technical Field

[0001] The 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 belt. Background Art

[0003] In the production process of optical cables, steel-plastic composite tape is a widely used armor material. Its main functions include shielding signals, enhancing the mechanical strength of optical cables, improving the corrosion resistance of optical cables, and extending the service life of optical cables. The steel-plastic composite tape is composed of a steel tape and a plastic film coated on the surface of the steel tape. Its performance directly affects the quality and use effect of the optical cable. Therefore, in the preparation process of the steel-plastic composite tape, testing its toughness is an indispensable step. Only after the toughness test is qualified can the steel-plastic composite tape be approved for shipment. However, through research, it is found that there is no toughness testing equipment specifically for the production process of steel-plastic composite tape on the market.

[0004] Traditional testing methods often require independent testing steps to evaluate the deformation resistance and durability of the steel-plastic composite belt after its preparation. 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 special testing equipment for the characteristics of steel-plastic composite belts may lead to inaccurate test results, making it difficult to fully reflect the actual performance of the steel-plastic composite belts.

[0005] Based on the above analysis, it can be seen that the deficiency of the existing technology lies in the lack of an integrated and precise steel-plastic composite tape toughness detection device, which cannot meet the needs of real-time monitoring of product quality and improving detection accuracy. This defect makes it easy for steel-plastic composite tapes to be defective after production, which not only affects the overall quality of the optical cable, but also has an adverse impact on production efficiency and economic benefits. Therefore, it is urgent to develop a cable manufacturing device dedicated to toughness detection during the production process of steel-plastic composite tapes to solve the above-mentioned problems of the existing technology and significantly improve product quality and production efficiency.

[0026] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0027] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] 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 in this application are described in detail.

[0029] 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 manufactured, so that after the high-strength steel-plastic composite belt is manufactured, the high-strength steel-plastic composite belt can be pushed into the workbench 1.

[0030] 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 passing 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 passing 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.

[0031] Exemplarily, the pushing mechanism 5 includes an upper pushing assembly 6 and a lower pushing assembly 7. The upper pushing assembly 6 is arranged horizontally on the workbench 1 and above the flexible bending mechanism 2, and the lower pushing assembly 7 is arranged horizontally on the workbench 1 and below the flexible bending mechanism 2. The upper pushing assembly 6 and the lower pushing assembly 7 are arranged horizontally on the workbench 1 and below the flexible bending mechanism 2. The upper pushing assembly 6 and the lower pushing assembly 7 are arranged opposite to each other in the vertical direction. The upper pushing assembly 6 and the lower pushing assembly 7 can generate a vertical thrust on the external bending assembly 3, so that the external bending assembly 3 is bent at the corresponding pushing position. When the component 3 generates a vertical downward thrust to make the corresponding pushing part of the external bending component 3 bend downward, the internal extrusion component 4 will generate a local bulge near the corresponding pushing part 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 part of the external bending component 3 bend upward, the internal extrusion component 4 will also generate a local bulge near the corresponding pushing part to generate a resistance force acting on the surface of the high-strength steel-plastic composite belt in the through channel 11.

[0032] 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 a steel belt and a 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.

[0033] Secondly, the design of the pushing mechanism 5 enhances the adjustability and precision of the equipment. The setting of the upper pushing component 6 and the lower pushing component 7 enables the bending force to be finely adjusted in different directions, thereby controlling the thrust of the external bending component 3, further improving the precise control of the bending process. This design can not only realize local detection of different parts of the steel-plastic composite belt, but also simulate a variety of different bending stress fields, further improving the comprehensiveness and authenticity of the detection process.

[0034] In addition, by applying precise resistance force during the bending process, the device can perform real-time quality control of the steel-plastic composite belt in the production line. Compared with the traditional post-test method, the device of the present invention can perform real-time toughness test at the tail end of the steel-plastic composite belt after it is manufactured, avoiding the waste of resources and production costs caused by the discovery of defective products in the later stage. This not only improves production efficiency, but also ensures that the steel-plastic composite belt meets the standard toughness requirements before leaving the factory, reducing the defective product rate in the production process.

[0035] 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 high toughness and high strength requirements.

[0036] In some embodiments, Figure 3 , Figure 4 As shown, the external bending assembly 3 includes an elastic membrane 31 and a bending tube segment 32. The bending tube segments 32 are axially connected and provided with a plurality of them, and the adjacent bending tube segments 32 are hingedly arranged. The elastic membrane 31 is wrapped between the plurality of bending tube segments 32. After the upper push assembly 6 and the lower push assembly 7 are started, a thrust is applied between the adjacent bending tube segments 32 to drive the adjacent bending tube segments 32 to bend. For example, the elastic membrane 31 is made of a polyurethane film, which has high elasticity, wear resistance, water resistance, oil resistance, good transparency, and is suitable for long-term use.

[0037] In this way, the axial connection and hinged arrangement of the bending pipe section 32 enable the bending pipe sections 32 to rotate relatively freely, so that the mechanical stress can be evenly distributed when the thrust is applied. This structural design ensures that when the high-strength steel-plastic composite belt passes, the external bending component 3 can adaptively adapt to the steel-plastic composite belt of different widths and thicknesses, avoiding the rigidity problem caused by the fixing of the bending pipe section 32.

[0038] The covering effect of the elastic membrane 31 enables the bending pipe section 32 to maintain a certain flexibility when being pushed, avoiding local damage that may be caused by direct contact with the surface of the steel-plastic composite belt. The elastic characteristics of the membrane can further adjust the distribution of the thrust, thereby providing a more uniform bending force, reducing the damage to the composite belt or uneven bending caused by excessive local stress. In addition, the starting pushing action of the upper pushing component 6 and the lower pushing component 7 enables precise thrust to be generated between adjacent bending pipe sections 32, driving the bending pipe section 32 to bend, and through this bending, the toughness of the steel-plastic composite belt is effectively tested.

[0039] In some embodiments, in combination 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 two adjacent rotation inclined surfaces, so that the adjacent bent pipe sections 32 can rotate relative to each other at the rotation gap 33.

[0040] On this basis, the setting of the connecting ear piece 321 enables the adjacent bending pipe sections 32 to be connected by a hinge and to 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 inclined plane allows the adjacent bending pipe sections 32 to rotate relative to each other at a specific rotating 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 rotating 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 the 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 capability during the production of the steel-plastic composite belt.

[0041] In some embodiments, in combination 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 are bent downward or upward.

[0042] In this way, the first cylinder 61 and the second cylinder 71 can generate a strong pushing effect through the expansion and contraction of their piston rods in the vertical direction, ensuring that the pushing roller applies 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 rotation gap 33. This alignment setting enables the pushing force of the pushing roller to accurately act on the bent pipe section 32, ensuring that the mechanical stress distribution during the bending process is uniform, and avoiding excessive or insufficient local stress.

[0043] Through the cooperation of the upper push component 6 and the lower push component 7, the equipment can realize the precise control of the bending pipe section 32 in both directions. In particular, under the pushing action of the first push roller 62 and the second push roller 72, the adjacent bending pipe sections 32 can bend downward or upward at the rotation gap 33, thereby effectively simulating the deformation performance of the steel-plastic composite belt under different conditions. This design not only improves the flexibility during the bending process, but also can adjust the bending angle and strength as needed, thereby realizing the precise detection of the toughness and bending performance of the steel-plastic composite belt, ensuring that it meets the production requirements, and further improving the detection accuracy and stability of the equipment.

[0044] It is worth noting that during the operation of the device, when the first cylinder 61 is in operation, 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.

[0045] In some embodiments, Figure 3 , Figure 4 As shown, the internal extrusion component 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 both radial sides of the connecting ear piece 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.

[0046] 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 another adjacent first cavity 322, and a portion of another airbag 41 extends from the second cavity 323 through the rotating gap 33 to another 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 protrusion toward the passage 11 under the action of the extrusion force and bending deformation.

[0047] On this basis, by introducing the design of the airbag 41 in the internal extrusion component 4, the accuracy and adaptability of the toughness and bending performance detection of the steel-plastic composite belt are further improved. The setting of the airbag 41 enables the device to form a local protrusion on the surface of the steel-plastic composite belt through the extrusion force of the airbag 41 during the rotation of the bending tube section 32, thereby simulating the deformation state that the steel-plastic composite belt may encounter in actual use. This local protrusion not only helps to perform fine physical testing on the steel-plastic composite belt, but also can accurately measure its deformation and stress response when bending.

[0048] Specifically, a first cavity 322 and a second cavity 323 are provided in the bending tube section 32, and the two are horizontally aligned on the adjacent bending tube section 32. This design enables the airbag 41 to freely transfer gas between two adjacent bending tube sections 32, ensuring that the expansion and extrusion 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, and the other part extends from the second cavity 323 to the adjacent first cavity 322, forming a closed loop structure. This design enables the airbag 41 to adjust its shape in real time during the bending process, generate precise resistance, and thus detect and evaluate the toughness of the steel-plastic composite belt.

[0049] In addition, when the first push roller 62 or the second push roller 72 moves in the vertical direction and applies thrust to the rotation gap 33, the airbag 41 automatically expands under the force and forms a local protrusion at the rotation gap 33 of the bending tube section 32. This local protrusion can not only accurately simulate the deformation process of the steel-plastic composite belt after being subjected to external extrusion force, but also effectively generate local resistance force, simulate the complex mechanical environment that may be encountered in actual use, and further improve the authenticity and reliability of toughness detection. Through this design, the equipment can dynamically adjust the strength and position of the local protrusion according to different detection requirements, thereby realizing comprehensive detection of different material properties.

[0050] In some embodiments, Figure 3 , Figure 4 As shown, a first radial cavity 324 and a second radial cavity 325 are provided 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 opened to connect and pass 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 opened to connect and pass through the channel 11.

[0051] 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 between the two second cavities 323, and the elastic sac 412 is embedded in the first radial cavity 324 and the second radial cavity 325, wherein, 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 pushed The force is converted into an expansion force of the elastic sac 412, so that the end of the elastic sac 412 away from the plastic sac 411 expands into the through channel 11; when the first push roller 62 or the second push roller 72 applies a pushing force to cause the adjacent bent tubes to bend relative to each other, the plastic sac 411 will be subjected to a deformation force and bend synchronously, and the deformation force will be converted into an expansion force acting on the elastic sac 412, so that the end of the elastic sac 412 away from the plastic sac 411 expands into the through channel 11. Exemplarily, a hole is also 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, and the elastic sac 412 can extend through the hole and enter the through channel 11 when it expands.

[0052] On this basis, the first radial cavity 324 and the second radial cavity 325 in the bending tube section 32 are respectively vertically connected to the first cavity 322 and the second cavity 323, and are connected to the through channel 11 through the openings at their ends. This design enables the airbag 41 system to apply force evenly and accurately during the bending process through the guidance of the cavity, ensuring a balanced pressure distribution during the detection process, thereby effectively simulating the external force in the actual working environment.

[0053] The airbag 41 is composed of a plastic sac 411 and an elastic sac 412. The plastic sac 411 is embedded between the first cavity 322 and the second cavity 323, while the elastic sac 412 is embedded in the radial cavity. The synergistic effect of the plastic sac 411 and the elastic sac 412 is the core innovation of the design. When the first push roller 62 or the second push roller 72 applies a driving force, the plastic sac 411 is subjected to the force and bends and deforms. At this time, the plastic sac 411 converts the driving force into the expansion force of the elastic sac 412, forcing the elastic sac 412 to expand into the passage 11. The expansion force of the elastic sac 412 can accurately control and simulate the mechanical response of the steel-plastic composite belt in actual work.

[0054] At the same time, when the driving force causes the adjacent bending tube section 32 to bend, the plastic capsule 411 will bend synchronously, generating a deformation force, which will be converted into an expansion force on the elastic capsule 412, causing the elastic capsule 412 to further expand and exert a local resistance force on the surface of the steel-plastic composite belt, thereby achieving accurate detection of the toughness and bending performance of the steel-plastic composite belt. Through the coordinated work of the plastic capsule 411 and the elastic capsule 412, the high-strength steel-plastic composite belt can be resisted by local protrusions while being bent by external forces, achieving the effect of simultaneously detecting the deformation resistance and durability of the high-strength steel-plastic composite belt, ensuring the accuracy and consistency of the mechanical response during the detection process.

[0055] In some embodiments, in combination Figure 3 , Figure 4 as well as Figure 5 Horizontal channels 12 are provided on both side walls of the workbench 1 located on the through channel 11. The horizontal channel 12 is connected to the through channel 11. Moving channels 13 are provided on the upper and lower sides of the horizontal channel 12 in parallel and connected. An elastic moving mechanism 8 is provided in the moving channel 13. The elastic moving mechanism 8 can move adaptively when the flexible bending mechanism 2 is bent to adaptively cooperate with the bending of the flexible bending mechanism 2.

[0056] Exemplarily, the elastic moving mechanism 8 includes a spring 81 and a moving block 82, the moving block 82 is slidably disposed in the moving channel 13, and the moving block 82 is hinged to the end of the bending tube section 32 at the end; further, 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, and the spring 81 always has a tendency to horizontally drive the moving block 82 to a side away from the flexible bending mechanism 2. Exemplarily, the horizontal channel 12 and the moving channel 13 are connected through a transverse groove, and the width of the transverse groove is smaller than the width of the horizontal channel 12 and the width of the moving channel 13, so that it can be ensured that the moving block 82 can stably move in the moving channel 13 and is not easy to fall into the horizontal channel 12.

[0057] Exemplarily, a swinging vertical groove 14 is further provided on the side wall of the workbench 1 close to the flexible bending mechanism 2. The swinging vertical groove 14 is connected to the moving channel 13, and the swinging vertical groove 14 can accommodate the bent pipe section 32 at the end in a bent state. After such arrangement, the horizontal channel 12 is connected to the through channel 11, so that the equipment can accurately control the moving path of the material during the bending process of the steel-plastic composite belt. In addition, the upper and lower sides of the horizontal channel 12 are provided with moving channels 13 connected thereto, and an elastic moving mechanism 8 is provided in the moving channel 13. This design can ensure that when the flexible bending mechanism 2 is bending, the elastic moving mechanism 8 can automatically adjust its position according to the deformation during the bending process, so that the equipment can adapt to different bending requirements. Through this design, the equipment can flexibly respond to and effectively cooperate with the action of the flexible bending mechanism 2 when the steel-plastic composite belt is bent, avoiding material damage or measurement errors caused by uneven bending or uneven force.

[0058] Furthermore, by sliding the moving block 82 in the moving channel 13 and hinged with the end of the bending tube section 32 at the end, it is ensured that the bending tube section 32 can be smoothly displaced during the bending process, and the spring 81 always drives the moving block 82 horizontally to the side away from the flexible bending mechanism 2. This design ensures that the equipment can be fine-tuned smoothly when bending the steel-plastic composite belt, and effectively avoids affecting the bending quality due to excessive or insufficient force.

[0059] In addition, a swinging vertical slot 14 is provided on the side wall of the workbench 1 near the flexible bending mechanism 2, which is connected to the moving channel 13 and can accommodate the bent pipe section 32 at the end in the bending state during the bending process. The design of the swinging vertical slot 14 enables the bent pipe section 32 to move more freely during the bending process, avoiding operational difficulties caused by space limitations or excessive friction resistance during the bending process, and further improving the stability of the equipment and the flexibility of operation.
