Description

Technical Field

[0001] This invention relates to the field of cable irradiation technology, specifically to an environmentally friendly flame-retardant cable irradiation testing device. Background Technology

[0002] In the production process of environmentally friendly flame-retardant cables, irradiation is used to improve the heat resistance of the cables. This causes the molecular chains of the polymer materials inside the cables to undergo a cross-linking reaction, forming a three-dimensional network structure. This improves the heat resistance of the cables and enhances their anti-aging ability. To test the performance of the irradiated cables, tests such as high temperature resistance and strong light irradiation are required. After the tests, a specialized testing device is used to inspect the outer periphery of the cables to determine whether the cables are damaged, thereby verifying whether the cables meet the standards.

[0003] Chinese Patent Publication No. CN212568401U discloses an automatic detection device for irradiation processing of halogen-free, low-smoke, flame-retardant cables. The device includes a base, with fixed frames on the upper outer side of each frame. A sliding groove is formed on the inner side of each fixed frame, and a slider is positioned inside the groove. A fixed wheel is positioned on the upper outer side of each slider. An electric lifting rod is positioned on the upper outer side of each base, with a bracket mounted on its upper end. A motor housing is positioned on the upper outer side of the bracket, with a dustproof mesh on the inner wall of the motor housing. A drive motor is mounted inside the motor housing, and a rotating block is connected to its lower end. A positioning groove is formed on the inner side of the rotating block, and a detector is mounted inside the positioning groove. A fixed rod is positioned on the upper outer side of the bracket, with a first rotating shaft positioned on the upper outer side of the fixed rod. A ball bearing is positioned inside the first rotating shaft, and a display is positioned above the surface of the ball bearing. A second rotating shaft is positioned inside the slider.

[0004] The above-mentioned method uses fixed wheels to fix the cable during inspection. However, the cable does not rotate around its own axis during the inspection process, and the inspection device can only inspect the upper half of the cable, not the lower half. Therefore, there will be a large blind spot during the inspection process, resulting in a large error in the inspection results. Moreover, most existing inspection equipment can only perform one type of inspection. In actual use, the cable is affected by multiple factors simultaneously. After inspection, a vision device is needed to visually identify the cable to confirm whether there are cracks on the cable surface. The entire inspection process is time-consuming. Summary of the Invention

[0005] To address the aforementioned issues, an environmentally friendly flame-retardant cable irradiation testing device is provided. This device comprises a transparent plate within a housing, multiple projection lamps positioned below the transparent plate, and a rolling unit positioned above the transparent plate. The cable is placed on the transparent plate, and a rotating belt within the rolling unit contacts the cable, pressing it against the transparent plate. Simultaneously, the rotating belt causes the cable to roll along the length of the housing on the transparent plate. The projection lamps activate as the rotating belt rotates, projecting light through the transparent plate onto the cable. The rolling cable is fully irradiated. Furthermore, the projected light has a specific temperature; a temperature sensor is positioned on one side of the gap where the cable rolls, ensuring the light remains within an environment between 60-80 degrees Celsius. The rotating belt causes the cable to roll back and forth on the transparent plate until the testing is complete.

[0006] To address the problems of existing technologies, this invention provides an environmentally friendly flame-retardant cable irradiation detection device, including a housing;

[0016] The follower plate passes horizontally through the inner ring of the rotating belt, the extension rod passes vertically through the follower plate and slides with the follower plate, and the upper end of the spring is fixedly connected to the follower plate.

[0017] The lifting frame is positioned above the rotating belt, and the lifting frame is fixedly connected to the follower plate;

[0018] The linear actuator is located at the top of the housing and is used to drive the lifting frame to move up and down.

[0019] Preferably, a plurality of rotating wheels that cooperate with the rotating belt drive are provided on one side of the inner ring of the rotating belt. The rotating wheels rise and fall synchronously with the rotating belt. A lifting groove is vertically opened on the side wall of the outer shell. The rolling unit also includes a follower frame, a rotary driver and an extension shaft.

[0020] The follower frame moves vertically within the lifting groove and rises and falls synchronously with the rotating belt;

[0021] The rotary drive is horizontally fixed on the follower frame;

[0022] The extension shaft is fixedly mounted on the output end of the rotary driver, and the rotary driver drives the rotating wheel to rotate through the extension shaft.

[0023] Preferably, telescopic covers that can cover the lifting slot are provided on the upper and lower parts of the follower frame.

[0024] Preferably, a clamping unit is also provided inside the housing, the clamping unit including a translation frame, a first roller and a second roller;

[0025] The translation frame is moved along the length of the outer shell and positioned on one side of the transparent plate;

[0026] There are two first rollers, which are arranged horizontally and form a groove between them to support the cable.

[0027] The second roller moves vertically and is positioned directly above the groove. Both the first and second rollers are in rolling contact with the cable.

[0028] Preferably, there are two translation frames, which are located on both sides of the transparent plate, and a connecting rod is provided between the two translation frames to fix them.

[0029] Preferably, a first slide is provided at the bottom of the translation frame along the length of the outer shell.

[0030] Preferably, a camera and a second sliding table are also provided below the transparent plate;

[0031] Multiple cameras are installed and arranged along the width of the housing;

[0032] The second slide is positioned below the camera along the length of the housing and is used to drive the camera to move along the length of the housing.

[0033] Preferably, lubricating oil is applied between the pressure plate and the rotating belt.

[0034] The advantages of this invention compared to the prior art are:

[0035] 1. This invention incorporates a transparent plate within a housing, with multiple projection lights positioned below the transparent plate and a rolling unit above it. The cable is placed on the transparent plate, and a rotating belt within the rolling unit contacts the cable, pressing it against the transparent plate. Simultaneously, the rotating belt causes the cable to roll along the length of the housing on the transparent plate. The projection lights activate as the belt rotates, projecting light through the transparent plate onto the cable. The rolling cable is fully illuminated. Furthermore, the projected light has a specific temperature; a temperature sensor is positioned on one side of the gap where the cable rolls, ensuring the light remains between 60-80 degrees Celsius. The rotating belt causes the cable to roll back and forth on the transparent plate until the testing is complete. In summary, this invention avoids blind spots during cable testing and allows for simultaneous light resistance and high-temperature resistance testing, more closely mimicking the actual operating environment of cables and resulting in more accurate test results.

[0036] 2. Before placing the cable onto the transparent plate, the cable must be horizontal and its extension direction parallel to the width of the casing. Then, the second roller is raised, and the cable is passed between the second roller and the groove. When the cable is fully inside the casing, the second roller is lowered. Under its own weight, the second roller presses the cable into the groove. When the rotating belt contacts the cable and causes it to roll, the cable rotates between the first and second rollers. The first and second rollers rotate synchronously with the cable. The clamping effect of the first and second rollers prevents the cable end from swinging when rolling on the transparent plate, thus avoiding non-detection damage to the cable during the detection process.

[0037] 3. When the rotating belt drives the cable rollers, the rotation speed of the belt is constant. Therefore, the rolling speed of the cable on the transparent plate is constant per unit time. As the cable rolls on the transparent plate, the first slide table drives the translation frame to move at a uniform speed. The distance the cable rolls on the transparent plate per unit time is the same as the distance the translation frame moves. This prevents the cable ends from bending due to being clamped by the first and second rollers while the cable is rolling, and also prevents the cable ends from slipping off the first and second rollers.

[0050] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0051] Reference Figures 1-6 An environmentally friendly flame-retardant cable irradiation testing device, comprising a housing 1;

[0052] It also includes a transparent panel 2, a projection lamp 21, and a scrolling unit 3;

[0053] The transparent plate 2 is horizontally arranged inside the housing 1, and the upper part of the transparent plate 2 is used to place the cable 4;

[0054] Multiple projectors 21 are provided, and the projectors 21 are arranged in an array below the transparent plate 2;

[0055] The rolling unit 3 is disposed above the transparent plate 2. The rolling unit 3 includes a rotating belt 31 rotatably disposed on the upper part of the transparent plate 2. There is a gap between the rolling unit 3 and the transparent plate 2 for placing the cable 4. The rotating belt 31 rolls with the peripheral wall of the cable 4. The horizontal end face of the rotating belt 31 in contact with the cable 4 is the working end face. A temperature sensor is disposed in the gap.

[0056] After cable 4 is irradiated, its heat resistance and resistance to light aging are significantly improved. However, existing testing equipment typically only tests a single property of cable 4. Before each test, cable 4 needs to be fixed. Furthermore, due to the small diameter of cable 4, it's impossible to fix the entire length of cable 4, preventing it from being rotated during testing. This can easily lead to blind spots in light irradiation and heat resistance tests, resulting in half of cable 4 being in the testing state and the other half in the non-testing state. This results in significant errors in judging the performance of cable 4. Moreover, because the cable... Cable 4 undergoes multiple tests, requiring repeated removal and installation. Furthermore, cable 4 is not only affected by a single external factor during use, and the experimental results are more theoretical than practical. After testing, the appearance of the tested cable 4 needs to be observed to determine if there is any damage or cracks. Because some cables 4 are quite thin, it's impossible to guarantee that the entire cable 4 is rotated when its angle is changed. The same problem occurs during testing: due to the thinness of the cable 4, the existing clamping mechanism cannot stably rotate it.

[0057] To avoid the above situation, the existing testing device was optimized so that it can simultaneously perform light resistance and temperature resistance tests on cable 4, while avoiding blind spots in the testing process and improving the accuracy of the test results. The specific structure and working process of this invention are as follows:

[0058] The rolling unit 3 also includes a mounting frame 311. The rotating belt 31 is mounted on the mounting frame 311. Multiple rotating wheels 312 are also provided on the mounting frame 311, all located on one side of the inner ring of the rotating belt 31. The rotating wheels 312 are arranged in a rectangular structure and are driven by the rotating belt 31. The mounting frame 311 can drive the rotating belt 31 to rise and fall synchronously. There is a highest position on the path of the mounting frame 311's rise and fall. When the cable 4 is not placed on the transparent plate 2, the mounting frame 311 is at its highest position, at which point the gap is largest. Before testing, the cable 4 is placed on the transparent plate 2 along the width direction of the outer casing 1. Then, the mounting frame 311 drives the rotating belt 31 to descend, and the gap gradually decreases. When the rotating belt 31 contacts the cable 4, the mounting frame 311 stops descending. At this point, the vertical gap is the same size as the diameter of the cable 4. Then, the rotating belt 31 begins to... The rotating belt 31 rotates, and the projection lamps 21 located below the transparent plate 2 are turned on. The projection lamps 21 illuminate the cable 4 and generate heat around the cable 4 while illuminating it. Since the projection lamps 21 are distributed in a matrix below the transparent plate 2, they can heat the entire gap. When the rotating belt 31 rotates, the cable 4 rolls along the length of the outer shell 1. The rolling cable 4 is not only illuminated by the projection lamps 21, but also subjected to the heat from the projection lamps 21, thus achieving simultaneous testing of the cable 4's resistance to light and high temperature. A temperature sensor is installed in the gap, and the temperature sensor is preset with a monitoring value controlled between 60 and 80 degrees Celsius. That is, the temperature generated by the projection lamps 21 in the gap should be between 60 and 80 degrees Celsius, thereby simulating the temperature generated by the cable 4 when exposed to light during use. Meanwhile, since the rotating belt 31 can drive the cable 4 to roll back and forth on the transparent plate 2, the cable 4 can be fully illuminated by the projection lamp 21 during rolling, and the cable 4 is heated more evenly, avoiding the phenomenon of blind spots in the detection of the cable 4. It is worth noting that the cable 4 must be in a straight line when inserted, that is, the length direction of the cable 4 is parallel to the width direction of the outer casing 1.

[0059] A transparent plate 2 is installed in the outer casing 1, and multiple projection lights 21 are installed below the transparent plate 2. A rolling unit 3 is installed above the transparent plate 2, so that the cable 4 is placed on the transparent plate 2. The rotating belt 31 in the rolling unit 3 contacts the cable 4 and presses the cable 4 onto the transparent plate 2. At the same time, the rotating belt 31 can also make the cable 4 roll along the length of the outer casing 1 on the transparent plate 2 during rotation. The projection lights 21 are activated when the rotating belt 31 rotates, and the light passes through the transparent plate 2 and is projected onto the cable 4. The rolling cable 4 can be fully illuminated by the light. At the same time, the light projected by the projection lights 21 has a certain temperature. A temperature sensor is installed on one side of the gap for the cable 4 to roll. Through the detection of the temperature sensor, the light is kept in an environment between 60-80 degrees. The rotating belt 31 makes the cable 4 roll back and forth on the transparent plate 2 until the detection ends. In summary, this invention avoids blind spots in the testing of cable 4, and can simultaneously conduct light resistance and high temperature resistance tests on cable 4, which is closer to the actual use environment of cable 4, making the test results more accurate.

[0060] Reference Figure 7 The rolling unit 3 includes a pressure plate 32 and a spring 33;

[0061] The pressure plate 32 is disposed on one side of the inner ring of the rotating belt 31 and provides support for the working end face of the rotating belt 31. When the rotating belt 31 rotates, the pressure plate 32 slides with the rotating belt 31.

[0062] Spring 33 is vertically mounted on the upper part of pressure plate 32, and the lower end of spring 33 is fixedly connected to pressure plate 32.

[0063] Spring 33 provides support for pressure plate 32. Since rotating belt 31 can circulate above transparent plate 2, when rotating belt 31 contacts cable 4, the support of rotating belt 31 for cable 4 is poor, which can easily cause the working end face of rotating belt 31 to be concave and bent, which in turn causes cable 4 to slip during the rolling process. However, after setting pressure plate 32 and spring 33, pressure plate 32 can provide support for rotating belt 31 during rotation, avoiding bending of rotating belt 31 when in contact with cable 4, and thus avoiding slippage of cable 4 due to insufficient pressure when rolling on transparent plate 2.

[0064] Reference Figure 7 and Figure 8 The rolling unit 3 also includes an extension rod 34, a follower plate 35, a lifting frame 36, and a linear driver 37;

[0065] The extension rod 34 is vertically fixed on the upper part of the pressure plate 32;

[0066] The follower plate 35 passes horizontally through the inner ring of the rotating belt 31, the extension rod 34 passes vertically through the follower plate 35 and slides with the follower plate 35, and the upper end of the spring 33 is fixedly connected to the follower plate 35.

[0067] The lifting frame 36 is positioned above the rotating belt 31, and the lifting frame 36 is fixedly connected to the follower plate 35;

[0068] Linear actuator 37 is located on the upper part of housing 1 and is used to drive the lifting frame 36 to rise and fall.

[0069] The connection between the lifting frame 36 and the follower plate 35 extends horizontally through the mounting frame 311. The connection is vertically mounted on the mounting frame 311. The linear actuator 37 raises the follower plate 35 via the lifting frame 36. When the rotating belt 31 just contacts the cable 4, the cable 4 is at one end of the pressure plate 32. Driven by the rotating belt 31, the cable 4 moves from one end of the pressure plate 32 to the other end, causing the pressure plate 32 to tilt when applying pressure to the rotating belt 31. To ensure the horizontal state of the pressure plate 32, an extension rod 34 is fixedly installed on the upper part of the pressure plate 32 and extends through the follower plate 35, ensuring that the pressure plate 32 will not tilt when subjected to force. It is worth noting that the linear actuator 37 is preferably a linear cylinder. Before the rotating belt 31 contacts the cable 4, the output end of the linear actuator 37 is in a retracted state, the mounting bracket 311 is in the highest position, and the spring 33 is in a non-compressed state. When the cable 4 is placed on the transparent plate 2 along the width direction of the outer casing 1, the linear actuator 37 drives the lifting frame 36 and the follower plate 35 to descend synchronously. At the same time, the mounting bracket 311 also descends synchronously with the lifting frame 36. When the rotating belt 31 contacts the cable 4, the mounting bracket 311 stops descending, while the lifting frame 36 continues to descend, causing the distance between the follower plate 35 and the lifting frame 36 to gradually shorten, and the spring 33 to gradually compress. The compressed spring 33 provides support force for the pressure plate 32.

[0070] Reference Figure 2 and Figure 10 Multiple rotating wheels 312 are provided on one side of the inner ring of the rotating belt 31, which are driven and cooperate with the rotating belt 31. The rotating wheels 312 rise and fall synchronously with the rotating belt 31. A lifting groove 11 is vertically opened on the side wall of the outer shell 1. The rolling unit 3 also includes a follower frame 38, a rotary driver 381 and an extension shaft 382.

[0071] The follower frame 38 is vertically movable and installed in the lifting groove 11 and rises and falls synchronously with the rotating belt 31;

[0072] The rotary actuator 381 is horizontally fixed on the follower frame 38;

[0073] The extension shaft 382 is fixedly mounted on the output end of the rotary driver 381, and the rotary driver 381 drives the rotating wheel 312 to rotate through the extension shaft 382.

[0074] The rotary driver 381 is preferably a servo motor, and the follower frame 38 is fixedly mounted on the mounting frame 311. When the mounting frame 311 moves in the vertical direction, the follower frame 38 moves synchronously with the mounting frame 311. Since the temperature inside the housing 1 is high during the detection process, which is not conducive to the normal operation of the rotary driver 381, the follower frame 38 is fixedly mounted on the mounting frame 311 in order to extend the service life of the rotary driver 381. The follower frame 38 extends from the inside of the housing 1 to the outside of the housing 1. By mounting the rotary driver 381 on the follower frame 38, the influence of the temperature inside the housing 1 on the rotary driver 381 is reduced.

[0075] Reference Figure 2 Telescopic covers 39 that can cover the lifting slot 11 are respectively provided on the upper and lower parts of the follower frame 38.

[0076] When the follower frame 38 moves in the vertical direction, the telescopic cover 39 extends and retracts, so that the follower frame 38 can rise and fall normally, while also preventing the high-temperature air inside the outer shell 1 from being discharged through the lifting groove 11.

[0077] Reference Figure 5 , Figure 6 and Figure 9 A clamping unit 5 is also provided inside the outer casing 1. The clamping unit 5 includes a translation frame 51, a first roller 52, and a second roller 53.

[0078] The translation frame 51 is movable along the length of the outer shell 1 and is disposed on one side of the transparent plate 2;

[0079] There are two first rollers 52, which are arranged horizontally and form a groove between the two first rollers 52 to support the cable 4.

[0080] The second roller 53 is vertically positioned directly above the groove, and both the first roller 52 and the second roller 53 are in rolling contact with the cable 4.

[0081] Before placing the cable 4 onto the transparent plate 2, the cable 4 needs to be horizontal and its extension direction parallel to the width direction of the outer casing 1. Then, the second roller 53 is raised, and the cable 4 is passed between the second roller 53 and the groove. When the cable 4 is fully inside the outer casing 1, the second roller 53 is lowered. Under its own weight, the second roller 53 presses the cable 4 into the groove. When the rotating belt 31 contacts the cable 4 and drives the cable 4 to roll, the cable 4 rotates between the first roller 52 and the second roller 53. The first roller 52 and the second roller 53 rotate synchronously with the cable 4. Under the clamping of the first roller 52 and the second roller 53, the end of the cable 4 is prevented from swinging when it rolls on the transparent plate 2, thus preventing non-detection damage to the cable 4 during the detection process.

[0082] Reference Figure 6 There are two translation frames 51, and the two translation frames 51 are located on both sides of the transparent plate 2 respectively. A connecting rod 54 is provided between the two translation frames 51 to fix the two translation frames 51.

[0083] By setting up two translation frames 51, each with a first roller 52 and a second roller 53, the clamping and restriction of both ends of the cable 4 is achieved, thus preventing the cable 4 from swinging rapidly when it rolls on the transparent plate 2.

[0084] Reference Figure 8 A first slide 55 is provided at the bottom of the translation frame 51 along the length of the outer shell 1.

[0085] When the rotating belt 31 drives the cable 4 rollers, the rotation speed of the rotating belt 31 is constant. Therefore, the rolling speed of the cable 4 on the transparent plate 2 is constant per unit time. When the cable 4 rolls on the transparent plate 2, the first slide 55 drives the translation frame 51 to move at a constant speed. In a unit time, the distance that the cable 4 rolls on the transparent plate 2 is the same as the distance that the translation frame 51 moves. This avoids the bending phenomenon at both ends of the cable 4 due to the clamping of the first roller 52 and the second roller 53 when the cable 4 rolls, and also avoids the end of the cable 4 slipping off the first roller 52 and the second roller 53.

[0086] Reference Figure 4 A camera 22 and a second slide 23 are also provided below the transparent panel 2;

[0087] Multiple cameras 22 are provided and arranged along the width direction of the housing 1;

[0088] The second slide 23 is positioned below the camera 22 along the length of the housing 1 and is used to drive the camera 22 to move along the length of the housing 1.

[0089] After the inspection is completed, there is no need to remove the cable 4. The second slide 23 drives the camera 22 to move, and the rotating belt 31 drives the cable 4 to roll again. The speed at which the second slide 23 drives the camera 22 is the same as the speed at which the cable 4 moves in the horizontal direction, thereby completing the inspection of whether the perimeter of the cable 4 is damaged, which improves the inspection efficiency.

[0090] Reference Figures 1-10 Lubricating oil is applied between the pressure plate 32 and the rotating belt 31.

[0091] By applying lubricating oil between the pressure plate 32 and the rotating belt 31, the coefficient of friction between the pressure plate 32 and the rotating belt 31 is reduced, thereby reducing the wear on the rotating belt 31 when the pressure plate 32 applies pressure to the rotating belt 31.

[0092] Working principle: The rolling unit 3 also includes a mounting frame 311. The rotating belt 31 is mounted on the mounting frame 311. Multiple rotating wheels 312 are also provided on the mounting frame 311, all located on one side of the inner ring of the rotating belt 31. The rotating wheels 312 are arranged in a rectangular structure and are driven by the rotating belt 31. The mounting frame 311 can drive the rotating belt 31 to rise and fall synchronously. There is a highest position on the path of the mounting frame 311's rise and fall. When the cable 4 is not placed on the transparent plate 2, the mounting frame 311 is at its highest position, at which point the gap is largest. Before testing, the cable 4 is placed on the transparent plate 2 along the width direction of the outer casing 1. Then, the mounting frame 311 drives the rotating belt 31 to descend, and the gap gradually decreases. When the rotating belt 31 contacts the cable 4, the mounting frame 311 stops descending. At this point, the vertical gap is the same size as the diameter of the cable 4. Then, the rotating belt 311... 1. The system begins to rotate, and simultaneously, the projection lamps 21 located below the transparent plate 2 are turned on, illuminating the cable 4. While illuminating the cable 4, the projection lamps 21 also generate heat around the cable 4. Since the projection lamps 21 are distributed in a matrix below the transparent plate 2, they can heat the entire gap. When the rotating belt 31 rotates, the cable 4 rolls along the length of the outer shell 1. The rolling cable 4 is not only illuminated by the projection lamps 21 but also subjected to their temperature, thus simultaneously testing the cable 4's resistance to light and high temperatures. A temperature sensor is installed in the gap, with a preset monitoring value controlled between 60-80 degrees Celsius. This means the temperature generated by the projection lamps 21 in the gap should be between 60-80 degrees Celsius, simulating the temperature generated by the cable 4 when exposed to light during use. Meanwhile, since the rotating belt 31 can drive the cable 4 to roll back and forth on the transparent plate 2, the cable 4 can be fully illuminated by the projection lamp 21 during the rolling process, and the cable 4 is heated more evenly, thus avoiding the phenomenon of detection blind spots in the cable 4.
