Description

Technical Field

[0001] The present invention relates to the technical field of roller wear resistance, and specifically provides a detection device for roller wear resistance testing. Background Art

[0002] A roller wear resistance testing machine is a device used to test the wear performance of rollers. Its working principle usually involves the layer to be worn of the specimen and the friction material (such as friction paper) rubbing against each other at a specified speed under the action of a load friction body. By measuring the changes in certain characteristics of the specimen before and after friction (such as the reduction in density, the reduction in coating thickness, or weight loss, etc.), the wear resistance of the specimen is judged.

[0003] Currently, the patent with the publication number CN213209804U discloses a wear resistance testing device for roller processing in a photovoltaic device, including a testing machine body, a testing wheel, a roller frame, and a fixing mechanism. An installation mechanism is provided on the top of the testing machine body. The installation mechanism includes an installation rod and an adjustment mechanism. The roller frame is detachably installed on the installation rod through the fixing mechanism. The fixing mechanism includes a rotating rod, a fixing block, a driving turbine, and a pressing component. The fixing block is fixed on the upper surface of the installation rod, the rotating rod is vertically installed in the fixing block, the driving turbine is fixedly sleeved on the surface of the rotating rod, and the two pressing components are meshed and connected with the driving turbine. The rotating rod and the fixing block are connected through a bearing.

[0004] Although the above device solves the problem of inconvenient installation of the roller frame, it still has the following deficiencies: in the wear resistance testing of various rubber-coated rollers, only a single roller can be tested, with low efficiency, and different environments of the roller, such as high temperature, cannot be tested during the test, thus limiting the comprehensiveness and practicality of the obtained data, resulting in relatively single test results and being difficult to comprehensively reflect the comprehensive performance of the roller in actual applications.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0018] Please refer to Figure 1 - Figure 8, A detection device for roller wear resistance testing, comprising a frame 1 and a tabletop 2. A fixed box 7 is connected to the top of the tabletop 2. One end of the fixed box 7 is fixedly connected to a main shaft 3. The bottom of the main shaft 3 is fixedly connected to a connecting shaft 16. The bottom of the connecting shaft 16 is fixedly connected to a rotating disk 15. A plurality of mounting blocks 18 for mounting rubber-coated rollers are connected inside the rotating disk 15. A fixed disk 13 is fixedly installed on the top of the tabletop 2. A grinding disk 17 is connected to the top of the fixed disk 13. A control unit 9 is connected to one side of the frame 1. A heating column 26 is electrically connected to the outside of the control unit 9. One end of the heating column 26 passes through the tabletop 2 and the fixed disk 13 and is inserted into the grinding disk 17. An environment simulation structure is connected to the bottom of the fixed disk 13.

[0019] In the roller wear resistance testing detection device of the present invention, when a rubber-coated roller needs to be subjected to wear resistance testing, the rubber-coated roller can be installed in the mounting block 18 inside the rotating disk 15. Then, the main shaft 3 is started through the control unit 9 to drive the connecting shaft 16 to rotate. The connecting shaft 16 drives the rotating disk 15, driving a plurality of rubber-coated rollers to conduct wear resistance testing inside the grinding disk 17 on the fixed disk 13. The grinding disk 17 can be set as a frosted disk. In this way, after the rubber-coated roller rotates and rubs, the wear degree of its surface thickness can be realized. At the same time, the heating column 26 can also be turned on through the control unit 9. When the heating column 26 heats up, it will heat the fixed disk 13 and the grinding disk 17. When the rubber-coated roller rotates under the drive of the connecting shaft 16, the grinding disk 17 will simulate a high-temperature environment. Of course, the temperature can be set through the control unit 9 and maintained after reaching the preset value, so as to realize the high-temperature environment simulation detection of the rubber-coated roller and make the wear resistance testing effect of the rubber-coated roller more comprehensive. The grinding disk 17 here can be set with different roughnesses, aiming to provide more effective and rapid real experimental data for the rubber-coated roller.

[0020] As a preferred technical solution of the present invention, the environment simulation structure includes a container 12 and a corrosive liquid located inside the container 12. A power pump is connected inside the container 12. The power pump is electrically connected to the control unit 9 through a cable. A liquid outlet pipe 29 is connected to the top of the container 12. The top of the liquid outlet pipe 29 is fixedly connected to the fixed disk 13. A liquid groove 27 is opened on the top surface of the fixed disk 13. The liquid outlet pipe 29 is communicated with the liquid groove 27. An outer cover 14 is fixedly connected to the top of the fixed disk 13. The outer cover 14 is located outside the liquid groove 27. The cross-section of the outer cover 14 is T-shaped. The height of the outer cover 14 is higher than the height of the mounting block 18.

[0021] Specifically, during the rotation of the rubber-coated roller, the power pump can be controlled to work through the control unit 9 to pump out the corrosive liquid (such as hydrogen peroxide) inside the container 12. The liquid is pumped from the container 12 to the liquid groove 27 through the liquid outlet pipe 29. With the setting of the outer cover 14, the liquid can enter the grinding disk 17, soaking the rubber-coated roller with the corrosive liquid, and thus making the performance detection of the rubber-coated roller more comprehensive.

[0022] The grinding disc 17 and the fixed disc 13 are detachably connected, and a gasket should be provided at the connection between the two to prevent liquid from leaking out from the connection between the two.

A rubber-coated roller mounting structure is connected inside the mounting block 18. The rubber-coated roller mounting structure includes a mounting shaft 20 and two spring bolts 23. The rubber-coated roller is clamped outside the mounting shaft 20. Two symmetrically arranged spring bolts 23 are threadedly connected inside the mounting block 18. The two spring bolts 23 pass through the mounting block 18, and nuts 25 are threadedly connected to the outside of one end of the mounting shaft 20.

[0026] Specifically, when the rubber-coated roller needs to be installed, the two spring bolts 23 can be passed through the mounting block 18 and the mounting shaft 20, and nuts 25 are threadedly connected to the outside of the lower end. With this setting, the rubber-coated roller can be clamped outside the mounting shaft 20 and installed with the mounting block 18, and then the mounting block 18 is inserted into the cross groove 21 in the rotating disc 15. Through the two spring bolts 23 and the mounting shaft 20, the rubber-coated roller can be fixed outside the mounting shaft 20 and fixedly installed with the mounting block 18, so that the mounting block 18 is connected outside the rotating disc 15.

[0029] As a preferred technical solution of the present invention, a jacking spring 24 is sleeved outside the spring bolt 23.

[0030] Specifically, a jacking spring 24 can be sleeved outside the spring bolt 23, which is convenient for increasing and decreasing the pressure of the rubber-coated roller, and making the detection effect better.

[0032] Specifically, when the rubber-coated roller rotates, it will rotate in the guide rail groove 19. At the same time, the convex platform 28 is provided in the guide rail groove 19, which can simulate the state of the roller under different road conditions and make the detection data more comprehensive.
