Description

Technical Field

[0001] This invention belongs to the field of seat belt abrasion resistance testing technology, specifically referring to an abrasion resistance testing device for seat belt production and its usage method. Background Technology

[0002] Safety belts, as a critical safety component installed on equipment, are commonly found in various means of transportation such as airplanes and automobiles, and are also used in high-altitude operations and performance scenarios to effectively protect the safety of users. They are primarily made of materials such as polyester, polypropylene, and nylon. During the production process, safety belts undergo sampling inspection, with a focus on testing their tensile strength and abrasion resistance.

[0003] The existing abrasion resistance testing equipment used in seat belt production has the following problems:

[0004] Existing abrasion resistance testing equipment for seat belt production lacks the ability to remove and collect burrs from the surface of the seat belt. On the one hand, this causes burrs to accumulate between the abrasive and the product, forming a buffer layer and affecting the authenticity of the abrasive's abrasion resistance test results. On the other hand, it is impossible to use the amount of burrs that fall off the product surface to help determine its abrasion resistance.

[0005] Therefore, it cannot meet the existing demand for abrasion resistance testing equipment used in seat belt production. Summary of the Invention

[0009] Preferably, the hair removal assembly includes a hair removal frame, an air pump, and an air extraction hose.

The filter layer is located inside the transparent cylinder near the exhaust valve. The hair suction assembly includes a hair suction groove, an air inlet, and a filter layer. The hair suction groove is located on the bottom wall of the adjusting block and is open at the bottom. The end of the air extraction hose away from the air pump passes through the adjusting block and extends into the hair suction groove. The air inlets are symmetrically located on the upper walls at both ends of the adjusting block and communicate with the hair suction groove. The filter layer is located inside the air inlet.

[0010] Specifically, a controller is provided on the side wall of the drive platform.

[0011] The controller is electrically connected to the drive motor, the guide electromagnet, and the air pump.

[0012] A method for using an abrasion resistance testing device for seat belt production includes the following steps:

[0013] Step 1: The return spring is in its shortened state under normal conditions. The guide column moves the friction adjustment block away from the upper wall of the strip groove. Lay the section of the safety belt to be tested flat on the upper wall of the strip groove. Insert the safety belt that extends beyond both ends of the strip groove into the fixed belt groove. Rotate the fixed belt bolt. The fixed belt bolt rotates along the test platform and fits against the safety belt, fixing the safety belt that extends beyond both ends of the strip groove inside the fixed belt groove. Rotate the adjusting bolt. The adjusting bolt rotates along the guide column and drives the friction adjustment block to descend. The friction adjustment block slides down along the guide column and drives the friction layer to fit against the safety belt placed inside the strip groove.

[0014] Step 2: The guide electromagnet is energized to generate magnetism. The guide electromagnet and the drive magnetic block are set with the same poles. The drive motor drives the drive shaft to rotate through the power end. When the drive shaft drives the drive magnetic block to rotate to be opposite the guide electromagnet, the drive magnetic block is fixed to the side wall of the drive shaft and pushes the guide electromagnet through repulsion. The guide electromagnet pushes the guide column with the elastic deformation of the return spring. The guide column slides along the side wall of the test platform through the sliding frame, causing the friction layer to rub against the seat belt to test the wear resistance of the seat belt. As the drive shaft rotates continuously, the drive shaft drives the drive magnetic block to be set opposite the guide electromagnet intermittently. When the guide electromagnet and the drive magnetic block are misaligned, the magnetic shielding layers set on both sides of the drive magnetic block can shield the magnetic field, so that the guide electromagnet is reset under the deformation of the return spring, so that the guide column can drive the friction layer to perform reciprocating test on the seat belt.

[0015] Step 3: During the testing of the seat belt on the friction layer, collect the burrs that fall off the surface of the seat belt. When the driving magnetic block pushes the guiding electromagnet with repulsive force to drive the guide column to test the seat belt using the friction layer, the guide column drives the burr-collecting groove to enter above the seat belt through the friction adjustment block. The magnetic field between the driving magnetic block and the guiding electromagnet is strong, and the driving magnetic block can quickly push the guiding electromagnet to move. The guiding electromagnet can drive the friction layer to quickly test the wear resistance of the seat belt through the guide column, which greatly improves the testing efficiency and shortens the testing cycle. Under the rapid friction between the friction layer and the seat belt, the amount of burrs falling off the surface of the seat belt can be increased.

[0016] Step 4: The air pump draws air from the suction tank through the suction hose. The air from the suction tank enters the transparent cylinder through the suction hose and connecting hose, where it becomes negative pressure. Outside air, after being filtered by the filter layer, enters the cavity formed by the suction tank and the strip groove. Under the action of the airflow, the burrs that have fallen off the surface of the seat belt are drawn into the transparent cylinder. The air inside the transparent cylinder is then filtered by the filter layer and discharged through the exhaust valve. The collected burrs adhere to the side of the filter layer away from the exhaust valve. After completing the abrasion resistance test of the seat belt, the operator unscrews the connecting hose from the side wall of the transparent cylinder, removes the transparent cylinder, and observes the amount of burrs inside. When the amount of burrs inside the transparent cylinder is small, it indicates that the abrasion resistance of the seat belt is high and meets the usage requirements; otherwise, it does not meet the usage requirements.

[0017] The beneficial effects achieved by this solution using the above structure are as follows:

[0018] Compared with existing technologies, this solution combines a pull-out testing mechanism with a burr-collecting detection mechanism. Through the combination of driving components, friction components, positioning components, force adjustment components, burr-collecting components, filtering components, and burr-absorbing components, it can perform abrasion resistance testing on longer seat belts, providing a more realistic and comprehensive evaluation of the seat belt's overall performance under actual use. Utilizing the strong magnetic field between the driving magnet and the guiding electromagnet, the guiding electromagnet can quickly drive the friction layer to test the seat belt's abrasion resistance under the deformation of the return spring. On the one hand, this shortens the testing cycle; under the same high-frequency conditions, it can quickly eliminate the worst-performing option by identifying which formulation shows wear signs faster. On the other hand, rapid pushing and pulling significantly increases the probability of burr removal, facilitating burr collection and reflecting the seat belt's abrasion resistance. Simultaneously, the filtering layer prevents external burrs from interfering with the final results, improving the testing efficiency of the seat belt. Attached Figure Description

[0039] The drive platform 1 is equipped with a controller 35 on its side wall.

[0040] The controller 35 is electrically connected to the drive motor 5, the guide electromagnet 12 and the air pump 24 respectively.

[0041] A method for using an abrasion resistance testing device for seat belt production includes the following steps:

[0042] Step 1: The return spring 36 is in the shortened state under normal conditions. The guide post 11 drives the friction adjustment block 18 away from the upper wall of the strip groove 14. The section of the safety belt to be tested is laid flat on the upper wall of the strip groove 14. The safety belt extending beyond both ends of the strip groove 14 is inserted into the fixed belt groove 15. The fixed belt bolt 16 is rotated. The fixed belt bolt 16 rotates along the test platform 2 and fits with the safety belt, fixing the safety belt extending beyond both ends of the strip groove 14 inside the fixed belt groove 15. The adjusting bolt 19 is rotated. The adjusting bolt 19 rotates along the guide post 11 and drives the friction adjustment block 18 to descend. The friction adjustment block 18 slides down along the guide post 11 and drives the friction layer 20 to fit with the safety belt placed inside the strip groove 14.

[0043] Step 2: The guide electromagnet 12 is energized to generate magnetism. The guide electromagnet 12 and the drive magnetic block 6 are set with the same pole. The drive motor 5 drives the drive shaft 37 to rotate through the power end. When the drive shaft 37 drives the drive magnetic block 6 to rotate to be opposite the guide electromagnet 12, the drive magnetic block 6 is fixed on the side wall of the drive shaft 37 and pushes the guide electromagnet 12 with repulsive force. The guide electromagnet 12 pushes the guide column 11 by the elastic deformation of the return spring 36. The guide column 11 slides along the side wall of the test platform 2 through the sliding frame 10, causing the friction layer 20 to rub against the seat belt to test the wear resistance of the seat belt. As the drive shaft 37 rotates continuously, the drive shaft 37 drives the drive magnetic block 6 to be set opposite the guide electromagnet 12 intermittently. When the guide electromagnet 12 and the drive magnetic block 6 are misaligned, the magnetic shielding layer 7 set on both sides of the drive magnetic block 6 can shield the magnetic field, so that the guide electromagnet 12 is reset under the deformation of the return spring 36, so that the guide column 11 can drive the friction layer 20 to perform reciprocating test on the seat belt.

[0044] Step 3: During the testing of the seat belt by the friction layer 20, the burrs that fall off the surface of the seat belt are collected. When the driving magnetic block 6 pushes the guiding electromagnet 12 with the repulsive force to drive the guide column 11 to test the seat belt using the friction layer 20, the guide column 11 drives the burr-collecting groove 32 to enter above the seat belt through the friction adjustment block 18. The magnetic field between the driving magnetic block 6 and the guiding electromagnet 12 is strong, and the driving magnetic block 6 can quickly push the guiding electromagnet 12 to move. The guiding electromagnet 12 can drive the friction layer 20 to quickly test the wear resistance of the seat belt through the guide column 11, which greatly improves the testing efficiency and shortens the testing cycle. Under the rapid friction between the friction layer 20 and the seat belt, the amount of burrs falling off the surface of the seat belt can be increased.

[0045] Step 4: The air pump 24 draws air from the suction groove 32 through the suction hose 25. The air from the suction groove 32 enters the transparent cylinder 27 through the suction hose 25 and the connecting hose 29, where it becomes negative pressure. Outside air enters the cavity formed by the suction groove 32 and the strip groove 14 after being filtered by the filter layer 30. Under the action of the airflow, the burrs that have fallen off the surface of the seat belt are drawn into the transparent cylinder 27. The air inside the transparent cylinder 27 is filtered by the filter layer 34 and discharged from the exhaust valve 28. The collected burrs adhere to the side of the filter layer 34 away from the exhaust valve 28. After completing the abrasion resistance test of the seat belt, the operator unscrews the connecting hose 29 from the side wall of the transparent cylinder 27 and takes out the transparent cylinder 27 to observe the amount of burrs inside. When the amount of burrs inside the transparent cylinder 27 is small, it indicates that the abrasion resistance of the seat belt is high and meets the usage requirements; otherwise, it does not meet the usage requirements.

[0046] In actual use, in the initial state, the return spring 36 is in the shortened state under normal conditions. The guide column 11 drives the friction adjustment block 18 away from the upper wall of the strip groove 14. The section of the safety belt to be tested is laid flat on the upper wall of the strip groove 14. The safety belt extending beyond both ends of the strip groove 14 is inserted into the fixed belt groove 15. The fixed belt bolt 16 is rotated, and the fixed belt bolt 16 rotates along the test platform 2 to fit with the safety belt, fixing the safety belt extending beyond both ends of the strip groove 14 inside the fixed belt groove 15. The adjusting bolt 19 is rotated, and the adjusting bolt 19 rotates along the guide column 11 to drive the friction adjustment block 18 down. The friction adjustment block 18 slides down along the guide column 11 to make the friction layer 20 fit with the safety belt placed inside the strip groove 14.

[0047] In the early stages of research and development, this device can be used to quickly screen the merits of different materials or process solutions. Under the same high-frequency conditions, by observing which formulation shows signs of wear faster, the worst-performing option can be quickly eliminated. The controller 35 controls the start of the guide electromagnet 12. The guide electromagnet 12 generates magnetism when energized. The guide electromagnet 12 and the drive magnetic block 6 are set with the same pole. The controller 35 controls the start of the drive motor 5. The drive motor 5 drives the drive shaft 37 to rotate through the power end. When the drive shaft 37 drives the drive magnetic block 6 to rotate to the position opposite to the guide electromagnet 12, the drive magnetic block 6 is fixed to the side wall of the drive shaft 37 and pushes the guide electromagnet 12 through repulsion. Since there is a strong magnetic field between the drive magnetic block 6 and the guide electromagnet 12, the guide electromagnet 12 uses the elastic deformation of the return spring 36 to push the guide column 11. The guide column 11 slides along the side wall of the test platform 2 through the sliding frame 10, causing the friction layer 20 to move in a straight line. The friction layer 20 and the seat belt rub against each other rapidly, thereby shortening the test cycle of the wear resistance of the seat belt and eliminating the worst-performing option.

[0048] As the drive shaft 37 continues to rotate, multiple sets of drive shafts 37 drive the drive magnetic block 6 to intermittently drive the guide column 11 to drive the friction layer 20 to rub against the seat belt. When the guide electromagnetic body 12 and the drive magnetic block 6 are misaligned, the magnetic shielding layer 7 set on both sides of the drive magnetic block 6 can shield the magnetic field. The guide electromagnetic body 12 is reset under the deformation of the reset spring 36, so that the guide column 11 can drive the friction layer 20 to perform reciprocating friction test on the seat belt.

[0049] During the friction test of the seat belt by the friction layer 20, excessive shedding of the seat belt means that the fibers on the surface of the webbing are being rapidly worn off and detached, resulting in a reduction in the effective cross-sectional area of ​​the webbing and a looser structure. This is a clear precursor to a significant decrease in the tensile strength of the seat belt. During the test of the seat belt by the friction layer 20, the burrs that fall off the surface of the seat belt are collected. When the driving magnetic block 6 pushes the guide electromagnet 12 with repulsive force to drive the guide column 11 to test the seat belt by the friction layer 20, the guide column 11 drives the burr-attracting groove 32 to enter above the seat belt through the friction adjustment block 18. The magnetic field between the driving magnetic block 6 and the guide electromagnet 12 is strong, and the driving magnetic block 6 can quickly push the guide electromagnet 12 to move. The guide electromagnet 12 can drive the friction layer 20 to quickly test the wear resistance of the seat belt through the guide column 11. Under the rapid friction and pushing and pulling between the friction layer 20 and the seat belt, the burrs on the surface of the seat belt fall off into the sealed cavity formed between the burr-attracting groove 32 and the strip groove 14.

[0050] The controller 35 controls the start of the air pump 24. The air pump 24 draws air from the inside of the hair suction groove 32 through the air suction hose 25. The air inside the hair suction groove 32 enters the transparent cylinder 27 through the air suction hose 25 and the connecting hose 29. The inside of the cylinder is changed to a negative pressure state. The outside air enters the cavity formed by the hair suction groove 32 and the strip groove 14 after being filtered by the filter layer 30. Under the action of the airflow, the burrs that fall off the surface of the seat belt are brought into the transparent cylinder 27. The air inside the transparent cylinder 27 is discharged from the exhaust valve 28 after being filtered by the filter layer 34. The collected burrs are attached to the side of the filter layer 34 away from the exhaust valve 28.

[0051] On the one hand, the transparent tube 27 collects the amount of burrs generated after friction on the surface of the seat belt, which makes it easier for operators to judge the wear resistance of the seat belt; on the other hand, as the test proceeds, the accumulated burrs will form a soft buffer layer, changing the direct contact state between the friction layer 20 and the seat belt, and preventing the subsequent friction from losing its authenticity due to the burr buffer layer. The suction effect of the suction hose 25 can eliminate the buffer layer formed by the burrs, ensuring the authenticity of the friction between the friction layer 20 and the seat belt.

[0052] After the abrasion resistance test of the seat belt is completed, the controller 35 controls the air pump 24 to stop working. The operator unscrews the connecting hose 29 from the side wall of the transparent cylinder 27, takes out the transparent cylinder 27, and observes the amount of burrs inside. When the amount of burrs inside the transparent cylinder 27 is small, it indicates that the abrasion resistance of the seat belt is high and meets the usage requirements. Otherwise, it does not meet the usage requirements. The above operation can be repeated for the next use.
