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. Step two: the guide electromagnet 12 is powered to generate magnetism, the guide electromagnet 12 is arranged with the same polarity as the driving magnetic block 6, the driving motor 5 drives the driving shaft 37 to rotate through the power end, the driving shaft 37 drives the driving magnetic block 6 to rotate to the opposite side of the guide electromagnet 12, the driving magnetic block 6 is fixed on the side wall of the driving shaft 37 and pushes the guide electromagnet 12 through repulsion, the guide electromagnet 12 pushes the guide column 11 through the elastic deformation of the reset spring 36, the guide column 11 drives the friction layer 20 to rub against the safety belt through the sliding frame 10, and the wear resistance of the safety belt is tested, with the continuous rotation of the driving shaft 37, the driving shaft 37 drives the driving magnetic block 6 to be arranged opposite to the guide electromagnet 12 intermittently, when the guide electromagnet 12 is arranged opposite to the driving magnetic block 6, the magnetic shielding layer 7 arranged on both sides of the driving magnetic block 6 can shield the magnetic field, so that the guide electromagnet 12 resets under the deformation of the reset spring 36, so that the guide column 11 can drive the friction layer 20 to reciprocatingly test the safety belt; Step three: collect the burrs falling off the surface of the safety belt during the test of the safety belt by the friction layer 20, when the driving magnetic block 6 pushes the guide electromagnet 12 through repulsion to drive the guide column 11 to test the safety belt by the friction layer 20, the guide column 11 drives the burr suction groove 32 to enter above the safety belt through the adjusting block 18, the magnetic field between the driving magnetic block 6 and the guide electromagnet 12 is strong, 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 safety belt through the guide column 11, greatly improving the test efficiency and compressing the test period, and under the rapid friction between the friction layer 20 and the safety belt, the burr falling off the surface of the safety belt can be increased; Step four: the air suction pump 24 sucks the air in the burr suction groove 32 through the air suction hose 25, the air in the burr suction groove 32 enters the inside of the transparent cylinder 27 through the connecting hose 29 after passing through the connecting hose 29, and the inside of the transparent cylinder 27 changes to a negative pressure state, the external air enters the cavity formed by the burr suction groove 32 and the strip-shaped groove 14 after being filtered by the filter layer 30, and under the action of the airflow, the burrs falling off the surface of the safety belt are sucked into the inside of the transparent cylinder 27, the air in the inside of the transparent cylinder 27 is filtered by the filter layer 34 and discharged from the exhaust valve 28, the collected burrs are attached to the side of the filter layer 34 away from the exhaust valve 28, after the wear resistance test of the safety belt is completed, 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 in the inside of the transparent cylinder 27, when the amount of burrs in the inside of the transparent cylinder 27 is small, it indicates that the wear resistance of the safety belt is high and meets the use requirements, otherwise, it does not meet the use requirements.

[0023] In specific use, in the initial state, the reset spring 36 is in a shortened state, the guide column 11 drives the adjusting block 18 away from the upper wall of the strip-shaped groove 14, a section of the safety belt to be tested is laid on the upper wall of the strip-shaped groove 14, the safety belt exceeding the two ends of the strip-shaped groove 14 is inserted into the fixed belt groove 15, the fixed belt bolt 16 is rotated, the fixed belt bolt 16 is combined with the safety belt along the test bench 2, the safety belt exceeding the two ends of the strip-shaped groove 14 is fixed in the fixed belt groove 15, the distance adjusting bolt 19 is rotated, the distance adjusting bolt 19 drives the adjusting block 18 to descend along the guide column 11, the adjusting block 18 is slid downward along the guide column 11 to drive the friction layer 20 to be combined with the safety belt placed in the strip-shaped groove 14; The device can be used for quickly screening the pros and cons of different materials or process schemes in the early stage of research and development; under the same high-frequency condition, by observing which formula appears wear signs faster, the worst option can be quickly ruled out, the controller 35 controls the starting of the guide electromagnet 12, the guide electromagnet 12 generates magnetism after being electrified, the guide electromagnet 12 is arranged with the same polarity as the driving magnetic block 6, the controller 35 controls the starting of the driving motor 5, the driving motor 5 drives the driving shaft 37 to rotate through the power end, the driving shaft 37 drives the driving magnetic block 6 to rotate to the position opposite to the guide electromagnet 12, the driving magnetic block 6 is fixed on the side wall of the driving shaft 37 and pushes the guide electromagnet 12 by repulsion, because there is a strong magnetic field between the driving magnetic block 6 and the guide electromagnet 12, the guide electromagnet 12 pushes the guide column 11 by the elastic deformation of the reset spring 36, the guide column 11 drives the friction layer 20 to move linearly through the sliding frame 10 along the side wall of the test bench 2, the friction layer 20 and the safety belt are quickly rubbed with each other, thereby shortening the test period of the wear resistance of the safety belt, and the worst option is further ruled out; With the continuous rotation of the driving shaft 37, the driving magnetic block 6 is intermittently driven by the driving shaft 37 to drive the guide column 11 to rub the friction layer 20 with the safety belt, when the guide electromagnet 12 and the driving magnetic block 6 are misaligned, the magnetic shielding layer 7 arranged on the two sides of the driving magnetic block 6 can shield the magnetic field, the guide electromagnet 12 is reset under the deformation of the reset spring 36, so that the guide column 11 can drive the friction layer 20 to reciprocally rub the safety belt for test; During the process of the friction layer 20 rubbing the safety belt, the excessive fuzz of the safety belt means that the fibers on the surface of the belt are being rapidly abraded and separated, resulting in a decrease in the effective cross-sectional area of the belt and a loosening of the structure, which is a clear sign of a significant decrease in the tensile strength of the safety belt. During the test of the safety belt by the friction layer 20, the collected fuzz is collected when the driving magnetic block 6 pushes the guide electromagnet 12 to drive the guide column 11 to rub the safety belt by the friction layer 20. When the driving magnetic block 6 and the guide electromagnet 12 have a strong magnetic field, 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 safety belt through the guide column 11. Under the rapid friction and pulling between the friction layer 20 and the safety belt, the fuzz on the surface of the safety belt falls off into the sealed cavity formed between the fuzz suction groove 32 and the strip-shaped groove 14. The controller 35 controls the start of the air suction pump 24, which extracts the air in the fuzz suction groove 32 through the air suction hose 25. The air in the fuzz suction groove 32 changes to a negative pressure state after entering the transparent cylinder 27 through the connecting hose 29. The external air enters the cavity formed by the fuzz suction groove 32 and the strip-shaped groove 14 after being filtered by the filter layer 30. Under the action of the airflow, the fuzz on the surface of the safety belt is brought into the transparent cylinder 27. The air in the transparent cylinder 27 is filtered by the filter layer 34 and discharged from the exhaust valve 28. The collected fuzz is attached to the side of the filter layer 34 away from the exhaust valve 28. On the one hand, the transparent cylinder 27 is used to collect the amount of fuzz generated after the surface of the safety belt is rubbed, which facilitates the operator to judge the wear resistance of the safety belt. On the other hand, as the test progresses, the accumulated fuzz forms a soft buffer layer, changing the direct contact state between the friction layer 20 and the safety belt, avoiding the loss of authenticity of subsequent friction due to the fuzz buffer layer. The suction effect of the air suction hose 25 can eliminate the buffer layer formed by the fuzz, ensuring the authenticity of the friction between the friction layer 20 and the safety belt. After completing the wear resistance test of the safety belt, the controller 35 controls the air suction pump 24 to stop working. 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 fuzz inside. When the amount of fuzz inside the transparent cylinder 27 is small, it means that the wear resistance of the safety belt is high and meets the use requirements. Otherwise, it does not meet the use requirements. The above operation can be repeated next time.
