Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric performance testing equipment, specifically a nonwoven fabric insulation performance testing equipment. Background Technology

[0002] Nonwoven fabrics are commonly used as insulation, heat insulation, and protective layers in electronic devices. To ensure the reliability and safety of nonwoven fabrics in actual use, their insulation performance needs to be tested before use. In actual use, nonwoven fabrics may be subjected to mechanical stresses such as friction, wear, and tension. Through friction and wear tests, these actual use conditions can be simulated to evaluate the changes in the insulation performance of nonwoven fabrics during long-term use.

[0003] Indirect measurements, such as changes in resistance or voltage, are not intuitive enough and require complex information processing and analysis. They also cannot accurately locate specific wear points or failure locations, and cannot achieve real-time monitoring, thus reducing the efficiency of nonwoven fabric insulation performance testing. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a non-woven fabric insulation performance testing device.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A nonwoven fabric insulation performance testing device includes an insulation performance testing machine and a metal rod. A groove is formed on one outer wall of the insulation performance testing machine, and a moving block is slidably connected to the inner wall of the groove. A hydraulic rod is installed on the inner wall of the insulation performance testing machine, and one end of the piston rod of the hydraulic rod is fixedly connected to the outer wall of the moving block. A mounting frame is fixedly connected to the bottom outer wall of the insulation performance testing machine. A mounting hole is formed on one outer wall of the mounting frame, and a handle is slidably connected to the inner wall of the mounting hole. A bevel gear is fixedly connected to the outer wall of the handle. A circular groove is formed on the bottom inner wall of the frame. A screw is rotatably mounted on the inner wall of the circular groove. A limit frame is connected to the outer wall of the screw via a thread. A support pad is fixedly connected to the top outer wall of the mounting frame. A non-woven fabric body is wound around the outer wall of the metal rod. A sliding hole is formed on one side outer wall of the top of the moving block. A support rod is slidably connected to the inner wall of the sliding hole. A detection head is installed on the bottom outer wall of the support rod. A wire is provided on the bottom outer wall of the insulation performance testing machine. A connecting clip is fixedly connected to the end of the wire away from the insulation performance testing machine.

[0007] Furthermore, the connecting clip is size-matched to the metal rod, the inner wall of the detection head is provided with metal wires, the metal wires are size-matched to the metal rod and the non-woven fabric body, and the detection head is located directly above the mounting frame.

[0008] Furthermore, a through hole is provided on the top outer wall of the mounting frame, the limiting frame is slidably connected to the inner wall of the through hole, and the first bevel gear and the second bevel gear mesh.

[0009] Furthermore, the top of the limiting frame is L-shaped, and anti-slip pads are adhered to the inner walls on both sides of the top of the limiting frame. A display screen and an operation panel are installed on one outer wall of the insulation performance testing machine.

[0010] Furthermore, the inner wall of the insulation performance testing machine is equipped with a time relay, an indicator light, and a processor; the inner wall of the moving block is equipped with a linear displacement sensor; the processor is electrically connected to the indicator light, the linear displacement sensor, the time relay, the display screen, the wires, the hydraulic rod, and the operation panel; and a power switch is installed on the top outer wall of the insulation performance testing machine.

[0012] The beneficial effects of this utility model are:

[0013] The system includes a metal rod, an insulation performance testing machine, a moving block, a limit frame, a display screen, and an operation panel. The metal wire inside the testing head contacts the outer wall of the non-woven fabric. A connector clamp at one end of the wire holds the end of the metal rod that is not covered by the non-woven fabric. Then, a hydraulic rod is activated, causing the moving block to periodically move left and right. The metal wire rubs against the non-woven fabric until it is worn through, and the wire contacts the metal rod, forming a circuit with the connector clamp and wire. An indicator light illuminates, and the friction time or number of cycles is recorded to evaluate the insulation durability and reliability of the non-woven fabric under specific conditions. The system is reliable; the metal wire wears through the metal rod to form a circuit, thereby controlling the indicator light to illuminate.

On the other side of the support rod, a fixed plate is connected to the limit rod, and the limit rod is slidably connected to the inner wall of the moving block to limit the support rod and improve structural stability.

[0022] The connecting clip 9 is adapted to the size of the metal rod 6. The inner wall of the detection head is provided with metal wires, which are adapted to the size of the metal rod 6 and the nonwoven fabric body 15. The detection head is located directly above the mounting frame 7. A through hole is opened on the outer wall of the top of the mounting frame 7. The limiting frame 14 is slidably connected to the inner wall of the through hole. The first bevel gear 17 and the second bevel gear 19 mesh. The top of the limiting frame 14 is L-shaped. Anti-slip pads 16 are glued to the inner walls on both sides of the top of the limiting frame 14.

An iron plate is provided at one end of the connecting clip 9 connected to the metal rod, and an insulating sleeve is provided at the other end for easy hand operation. The insulation performance of nonwoven fabric is closely related to its physical integrity. When nonwoven fabric is worn, its thickness will decrease and its structural integrity will decrease, resulting in a decrease in insulation performance. Through friction and wear testing, the change in insulation performance of nonwoven fabric under different degrees of wear can be evaluated.

[0023] The inner wall of the aforementioned insulation performance testing machine 1 is equipped with a time relay, an indicator light, and a processor. The inner wall of the moving block 11 is equipped with a linear displacement sensor.

The metal wire rubs the non-woven fabric until the non-woven fabric body 15 is worn through and the metal wire contacts the metal rod 6. It forms a circuit with the connecting clamp 9 and the wire 10. The indicator light lights up and records the friction time or number of times from start to finish to evaluate the insulation durability and reliability of the non-woven fabric body 15 under specific conditions. Anti-slip pads 16 are set on the limit frame 14 to make it more secure and less likely to fall off when clamping and limiting the metal rod 6 and the non-woven fabric body 15. On the other side of the support rod 3, it is connected to the limit rod 13 through a fixing plate. The limit rod 13 is slidably connected to the inner wall of the moving block 11 to limit the support rod 3 and improve the structural stability.
