Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to an insulation testing device for cable production. Background Technology

[0002] With the rapid development of society and economy, wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of the following parts: one or more insulated cores, and their respective possible covering layers, overall protective layer and outer sheath. Cables may also have additional uninsulated conductors. Insulation testing devices are equipment used to test the performance of wires and cables.

[0003] In the prior art, patent publication number CN219997226U discloses an insulation testing device for cable production, including support plates. A first support sleeve is fixedly connected between the left side of the top center of two support plates. A conveyor belt is arranged between the two support plates. A second support sleeve is fixedly connected between the top center of the support plates. Evenly distributed fixed plates are fixedly connected to the outer wall of the conveyor belt. A hot air blower is fixedly connected to the top center of the first support sleeve. A fixed roller is rotatably connected through two adjacent fixed plates. In this invention, the two ends of the cable are first fixed by the fixed sleeve through an electric push rod and a fixing ring in the inner wall, preventing inaccurate insulation measurement due to insecure fixing.

[0004] Although the aforementioned insulation testing device for cable production can achieve the effect of insulation testing of cables through insulation resistance testers and electric push rods, it still has the following shortcomings in practical applications: when testing cables, the cables are in a straight position, and it is impossible to test the insulation of cables in a bent position during actual use, resulting in poor test results. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an insulation testing device for cable production.

[0006] To achieve this objective, the present invention adopts the following technical solution: an insulation testing device for cable production, comprising a workbench, a conveying component, a guiding component, and a second detection component fixedly installed on the top of the workbench, the guiding component being located between the conveying component and the second detection component, the conveying component comprising a fixed frame fixedly installed on the top of the workbench, two conveying frames fixedly installed on the inner wall of the top of the fixed frame, two conveying rollers rotatably installed inside each conveying frame, a first detection component fixedly installed on the top of the fixed frame, and a winding component rotatably installed on the top of the workbench, the winding component being located inside the second detection component.

[0007] Preferably, the first detection component includes a cylinder fixedly installed on the top of the mounting frame, the telescopic shaft of the cylinder passing through the top wall of the mounting frame, and an insulation resistance tester fixedly connected thereto.

[0008] Preferably, the guiding assembly includes a guide frame fixedly installed on the top of the workbench, with a threaded rod rotatably installed on the upper and lower inner walls of the guide frame, and a servo motor fixedly installed on the top of the guide frame. The output end of the servo motor passes through the top wall of the guide frame and is fixedly connected to the top end of the threaded rod.

[0009] Preferably, a sliding rod is fixedly installed on the upper and lower inner walls of the guide frame, and a lifting block is slidably sleeved on the periphery of the sliding rod and the threaded rod, and the lifting block is threadedly engaged with the threaded rod, and a guide ring is fixedly installed at the bottom of the lifting block.

[0010] Preferably, the winding assembly includes a turntable rotatably mounted on the top of the workbench and a drive motor fixedly mounted on the inner wall of the top of the workbench. The output end of the drive motor passes through the top wall of the workbench and is fixedly connected to the bottom of the turntable.

[0011] Preferably, a fixing post is fixedly installed on the top of the turntable, a take-up drum is sleeved around the fixing post, and a clamping nut is threaded onto the outer periphery of the fixing post. The take-up drum is clamped and fixed on the turntable by the clamping nut.

[0012] Preferably, the second detection component includes a shield that is fixedly installed on the top of the workbench. Multiple electric field sensors are uniformly fixedly installed on the inner wall of the shield, and an opening is provided on the side of the shield near the guide ring.

[0013] The beneficial effects of this utility model are as follows: When using this device, the cable is passed sequentially between two conveyor rollers, then through a guide ring and a through-hole to connect with the take-up drum. The drive motor is started to rotate the turntable on top of the worktable, and the take-up drum follows the turntable to wind up the cable. The cylinder is started to raise and lower the insulation resistance tester. Once the insulation resistance tester is adjusted to a suitable height, it is turned on to perform insulation testing on the cable in a horizontal or vertical state. The servo motor is started to rotate the threaded rod between the upper and lower inner walls of the guide frame. The rotation of the threaded rod causes the lifting block to move around the threaded rod and the sliding rod. The device reciprocates, causing the guide ring to reciprocate. This reciprocating motion of the guide ring, in turn, causes the cable inside the guide ring to reciprocate, ensuring the cable is evenly wound up by the winding drum. Multiple electric field sensors monitor the electric field distribution on the surface and inside of the bent cable in real time, detecting the integrity of the insulation layer. A shielding cover blocks external electromagnetic interference, ensuring the measurement accuracy of the sensors. These features enable the device to perform insulation testing not only on cables in both straight and bent states, enhancing the insulation detection effect, but also ensure that the cable is evenly wound up after testing.

[0022] Example 1

[0023] like Figure 1-3As shown, the present invention proposes an insulation testing device for cable production, comprising a workbench 1. A conveying assembly 2, a guiding assembly 4, and a second detection assembly 6 are fixedly installed on the top of the workbench 1. The guiding assembly 4 is located between the conveying assembly 2 and the second detection assembly 6. The conveying assembly 2 includes a fixed frame 21 fixedly installed on the top of the workbench 1. Two conveying frames 22 are fixedly installed on the inner wall of the top of the fixed frame 21. Two conveying rollers 23 are rotatably installed inside each of the conveying frames 22. A first detection assembly 3 is fixedly installed on the top of the fixed frame 21. A winding assembly 5 is rotatably installed on the top of the workbench 1, and the winding assembly 5 is located inside the second detection assembly 6.

[0024] In this embodiment: the first detection component 3 includes a cylinder 31 fixedly installed on the top of the fixed frame 21. The telescopic shaft of the cylinder 31 passes through the top wall of the fixed frame 21 and is fixedly connected to an insulation resistance tester 32. This configuration allows the cylinder 31 to drive the insulation resistance tester 32 to move up and down. When the insulation resistance tester 32 is adjusted to a suitable height, it can be turned on to perform insulation testing on horizontal and vertical cables. The guide component 4 includes a guide frame 41 fixedly installed on the top of the workbench 1. A threaded rod 42 is rotatably installed on the upper and lower inner walls of the guide frame 41. A servo motor 43 is fixedly installed on the top of the guide frame 41. The output end of the servo motor 43 passes through the top wall of the guide frame 41 and is fixedly connected to the top end of the threaded rod 42. The fixed connection allows the starter servo motor 43 to drive the threaded rod 42 to rotate between the upper and lower inner walls of the guide frame 41. A slide rod 44 is fixedly installed on both the upper and lower inner walls of the guide frame 41. A lifting block 45 is slidably sleeved around the slide rod 44 and the threaded rod 42, and the lifting block 45 is threadedly engaged with the threaded rod 42. A guide ring 46 is fixedly installed at the bottom of the lifting block 45. This configuration allows the rotation of the threaded rod 42 to drive the lifting block 45 to reciprocate up and down around the threaded rod 42 and the slide rod 44, thereby driving the guide ring 46 to reciprocate up and down. The cable passes through the guide ring 46, and when the guide ring 46 rises and falls, it drives the cable inside the guide ring 46 to rise and fall, thus achieving uniform winding of the cable by the winding assembly 5.

[0025] Example 2

[0026] like Figure 1-3As shown, the insulation testing device for cable production proposed in this utility model, compared with Embodiment 1, further includes a winding assembly 5 comprising a turntable 51 rotatably mounted on the top of the workbench 1 and a drive motor 52 fixedly mounted on the inner wall of the top of the workbench 1. The output end of the drive motor 52 penetrates the top wall of the workbench 1 and is fixedly connected to the bottom of the turntable 51. This arrangement allows the drive motor 52 to rotate the turntable 51 on the top of the workbench 1. A fixing post 53 is fixedly mounted on the top of the turntable 51, and a winding drum 54 is sleeved around the fixing post 53. A clamping nut 55 is threaded onto the outer side of the fixing post 53, and the winding drum 54 is clamped and fixed on the turntable 51 by the clamping nut 55. This arrangement allows the winding drum 54 to be inserted into the turntable 51. Around the fixed column 53, the winding drum 54 is pressed and fixed onto the turntable 51 by rotating the clamping nut 55. The winding drum 54 rotates with the turntable 51 to wind up the cable. The second detection component 6 includes a shield 61 fixedly installed on the top of the workbench 1. Multiple electric field sensors 62 are evenly fixedly installed on the inner wall of the shield 61. The shield 61 has an opening 63 on the side near the guide ring 46. Through this setting, the cable passing through the guide ring 46 enters the shield 61 through the opening 63 and is wound up by the winding drum 54. The multiple electric field sensors 62 can monitor the electric field distribution on the surface and inside of the cable in a bent state in real time and detect the integrity of the insulation layer. The shield 61 can shield external electromagnetic interference and ensure the measurement accuracy of the sensors.

[0027] Working principle: When using this device, the cable is passed sequentially between the two conveyor rollers 23, then through the guide ring 46 and the through-hole 63 to connect with the take-up drum 54. The drive motor 52 is started to rotate the turntable 51 on top of the worktable 1. The take-up drum 54 follows the turntable 51 to rotate, thus winding the cable. The cylinder 31 is started to raise and lower the insulation resistance tester 32. Once the insulation resistance tester 32 is adjusted to the appropriate height, it is turned on to perform insulation testing on the cable in its horizontal or vertical state. The servo motor 43 is started to drive the threaded... The rod 42 rotates between the upper and lower inner walls of the guide frame 41. The rotation of the threaded rod 42 will drive the lifting block 45 to reciprocate around the threaded rod 42 and the slide rod 44, thereby driving the guide ring 46 to reciprocate. When the guide ring 46 reciprocates, it will drive the cable inside the guide ring 46 to reciprocate, so that the cable is evenly wound by the winding drum 54. Multiple electric field sensors 62 can monitor the electric field distribution on the surface and inside of the bent cable in real time and detect the integrity of the insulation layer. The shielding cover 61 can shield external electromagnetic interference and ensure the measurement accuracy of the sensors.
