[0023] In order to make the technical means, creative features, achieved purposes and functions realized by the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1 to 3 shown, a roller fatigue test device described in an embodiment of the utility model includes a detection frame 1; a roller to be tested 5 is installed in the middle of the detection frame 1; a belt 6 is installed on the detection frame 1; the belt 6 is sleeved on the roller to be tested 5; a host controller 3 is installed on the side wall of the detection frame 1; the host controller 3 is used to control the rotation of the belt 6; a display panel 2 is installed on the side wall of the detection frame 1; four temperature detectors 4 are installed on the side wall of the detection frame 1; the temperature detectors 4 are respectively arranged at the four corners of the detection frame 1. During operation, the roller to be tested 5 that needs to be subjected to fatigue test is installed on the detection frame 1, the belt 6 is started by controlling the switch of the host controller 3, and the belt 6 drives the roller to be tested 5 to rotate continuously through friction. The time, temperature and other conditions during the test of the roller to be tested 5 are displayed through the display panel 2. The temperature generated by friction during the rotation of the roller is detected by the temperature detectors 4 arranged at the four corners of the detection frame 1. The speed of the belt 6 and the friction force on the roller to be tested 5 can be adjusted by controlling the host controller 3. By performing fatigue tests on rollers under different working conditions, a more detailed service life of the roller can be obtained, which is convenient for better reminding customers to replace it during later sales, reducing the problem of accidents caused by the roller wearing to the limit during use. At the same time, some parameters can be obtained through the fatigue test, such as how long the high temperature lasts before wear occurs, making the roller safer during use.

[0025] As Figures 1 to 4As shown, multiple sets of support springs 7 are fixedly connected to the inner sidewall of the detection frame 1; the support springs 7 are symmetrically arranged on the detection frame 1; a tray 8 is fixedly connected to the end of the support spring 7; a pair of fixed plates 9 are fixedly connected to the bottom of the tray 8; the fixed plates 9 are symmetrically arranged on the tray 8; a wear-resistant roller 10 is rotatably connected between the pair of fixed plates 9. During operation, by adding a load to the tray 8, the tray 8 moves downward under the action of gravity, so that the wear-resistant roller 10 located below the tray 8 presses against the surface of the belt 6, and then by making the middle of the belt 6 concave, the tension of the belt 6 is increased, and then the friction force of the belt 6 on the roller 5 to be measured is increased. By adjusting the friction force of the belt 6 on the roller 5 to be measured, the service life of the roller 5 to be measured under different pressure conditions is tested, the accuracy and application range of the test on the roller 5 to be measured are improved. At the same time, a wear-resistant roller 10 is provided between the tray 8 and the belt 6, which can change the extrusion of the tray 8 on the belt 6 from sliding friction to rolling friction, reduce the friction and wear on the surface of the belt 6, and improve the service life of the belt 6.

[0026] As Figure 3 and Figure 4 shown, multiple guide grooves 11 are fixedly connected to the inner sidewall of the detection frame 1; multiple guide rods 12 are fixedly connected to the sidewalls at the ends of the tray 8; the ends of the guide rods 12 are arranged inside the guide grooves 11 and are in sliding fit with the guide grooves 11. During operation, by providing guide grooves 11 on the detection frame 1, when the tray 8 moves downward, the tray 8 moves through the guide rods 12 inside the guide grooves 11, so that the tray 8 can descend vertically under the pressure of the load, improving the stability of the tray 8 during operation, reducing the possibility that the tray 8 sways left and right, resulting in unstable friction of the belt 6 on the roller 5 to be measured and deviation of the test results, and improving the accuracy of the test results.

[0027] As Figures 2 to 5 shown, a blower 13 is fixedly connected to the sidewall of the detection frame 1; an air duct 14 is fixedly connected to the output end of the blower 13; the end of the air duct 14 is fixedly connected to the top sidewall of the detection frame 1; multiple groups of nozzles 15 are fixedly connected to the middle of the air duct 14; the nozzles 15 are arranged in an array on the air duct 14; the air duct 14 and the nozzles 15 are communicated with each other; the ends of the nozzles 15 face the surface of the belt 6. During operation, by turning on the switch of the blower 13, the blower 13 conveys air into the air duct 14, and then the air flow is conveyed to the nozzles 15 through the air duct 14, and the air flow ejected from the ends of the nozzles 15 blows on the surface of the belt 6, thereby cleaning the impurities on the surface of the belt 6, reducing the wear of the impurities on the surface of the belt 6 on the wear-resistant roller 10, and improving the protection effect on the belt 6.

[0028] As Figure 4As shown, a pair of connecting plates 16 are fixedly connected to the side wall of the tray 8; multiple groups of cleaning brushes 17 are fixedly connected to the bottom side wall of the connecting plates 16; the cleaning brushes 17 are arranged in an array on the connecting plates 16; the cleaning brushes 17 are in contact with the surface of the belt 6. During operation, by providing the cleaning brushes 17 on the tray 8 that are in contact with the surface of the belt 6, when the belt 6 rotates, the cleaning brushes 17 can clean the impurities on the surface of the belt 6, causing the impurities to fall off from the belt 6, making it easier to be blown off, and improving the cleaning effect on the surface of the belt 6.

[0029] As Figure 4 shown, a pulling rope 18 is fixedly connected between multiple groups of the cleaning brushes 17; the pulling rope 18 is arranged in the middle of the cleaning brushes 17. During operation, by providing the pulling rope 18, the connection between multiple groups of cleaning brushes 17 can be made stronger, and the cleaning effect of the cleaning brushes 17 can be enhanced.

[0030] Working principle: The roller to be tested 5 that needs to undergo fatigue testing is installed on the detection frame 1. By turning on the belt 6 through the switch of the main control controller 3, the belt 6 drives the roller to be tested 5 to rotate continuously through friction. The display panel 2 displays the time, temperature, etc. during the testing of the roller to be tested 5. The temperature sensors 4 arranged at the four corners of the detection frame 1 detect the temperature generated by friction during the rotation of the roller. The main control controller 3 can adjust the speed of the belt 6 and the friction force on the roller to be tested 5. By conducting fatigue tests on rollers in different working conditions, a more detailed service life of the roller can be obtained, which is convenient for better reminding customers to replace it during later sales, reducing the problem of accidents caused by the roller wearing to the limit during use. At the same time, some parameters are obtained through the fatigue test, such as how long the high temperature lasts before wear occurs, making the roller safer during use.

[0031] By adding a load to the tray 8, the tray 8 moves downward under the action of gravity, and then the anti-wear roller 10 located below the tray 8 presses against the surface of the belt 6, causing a depression in the middle of the belt 6, improving the tension of the belt 6, and thus increasing the friction force of the belt 6 on the roller to be tested 5. By adjusting the friction force of the belt 6 on the roller to be tested 5, the service life of the roller to be tested 5 under different compression conditions can be tested, improving the accuracy and application range of the test on the roller to be tested 5. At the same time, an anti-wear roller 10 is provided between the tray 8 and the belt 6, which can change the extrusion of the tray 8 on the belt 6 from sliding friction to rolling friction, reducing the frictional wear on the surface of the belt 6 and increasing the service life of the belt 6.

[0032] By turning on the switch of the blower 13, the blower 13 conveys air into the inside of the air duct 14, and then the air flow is conveyed to the nozzle 15 through the air duct 14. The air flow ejected from the end of the nozzle 15 blows onto the surface of the belt 6, thereby cleaning the impurities on the surface of the belt 6, reducing the wear of the anti-wear roller 10 caused by the impurities on the surface of the belt 6, and improving the protection effect on the belt 6.

[0033] By turning on the switch of the blower 13, the blower 13 conveys air into the inside of the air duct 14, and then the air flow is conveyed to the nozzle 15 through the air duct 14. The air flow ejected from the end of the nozzle 15 blows onto the surface of the belt 6, thereby cleaning the impurities on the surface of the belt 6, reducing the wear of the anti-wear roller 10 caused by the impurities on the surface of the belt 6, and improving the protection effect on the belt 6.

[0034] By providing a cleaning brush 17 on the tray 8 that is in contact with the surface of the belt 6, when the belt 6 rotates, the cleaning brush 17 can clean the impurities on the surface of the belt 6, causing the impurities to fall off from the belt 6 and being more easily blown off, thereby improving the cleaning effect on the surface of the belt 6.

[0035] By providing a pull rope 18, the connection between multiple cleaning brushes 17 can be enhanced, making the cleaning effect of the cleaning brushes 17 stronger.
