Description

Technical Field

[0001] The present invention relates to the technical field of mirror roller testing, and particularly to a multi-functional comparative testing device for the roller body of a mirror roller. Background Art

[0002] Mirror rollers are widely used in various industrial fields, such as textile, leather, plastic processing, etc. Different fields have different performance requirements for mirror rollers. Through comparative testing, problems that may exist in the manufacturing or use process of mirror rollers, such as uneven surfaces and unstable dimensions, can be found, so as to be repaired and improved in time, and the durability and stability of mirror rollers can be improved. Therefore, a multi-functional comparative testing device for the roller body of a mirror roller is needed.

[0003] Currently, when conducting inspection work on a mirror roller after processing: 1. Usually, manual external observation is carried out to identify whether corrosion or defects occur on the outer surface of the mirror roller. After identification, the equipment is used to detect this area, so as to repair and improve the roller body in time. During the observation process, due to the large volume and quantity of the roller body, and the narrow defect area, there is a possibility of missing areas during manual observation, thus failing to timely discover problematic materials; 2. During the production process, it is necessary to test the quality of products, but the test samples themselves may have quality problems, which will delay the accuracy of test results; 3. During the operation of the mirror roller, the roller body will be damaged due to different reasons. Some damages are obvious and can be directly repaired, while the other part has a small diameter and a deep length, which is difficult to be directly and timely discovered visually. Over time, it may affect the service life of the roller body; 4. Mirror rollers will be used in some special environmental occasions, and there may be some corrosive liquids and gases in these environments. The roller body works in these environments and is more likely to be worn, oxidized, and corroded over time; Therefore, a multi-functional comparative testing device for the roller body of a mirror roller is proposed.

[0022] Working principle: Take the test roller 4 and place one end of it in the output shaft 321 of the first test bench 3. At the same time, change the length of the adjusting bracket 34 according to the position of the other end, so that the other end of the test roller 4 is connected in the adjusting bracket 34. Then adjust the clamping block 322 to clamp the test roller 4. Take another test roller 4 and install it in the second test bench 31 in the same way. At this time, control the first motor 25 to rotate and rotate the first rotating frame 62 to the top surface; When conducting a comparative test of hardness, control the steering motor to rotate. The first driving block 71 will rotate by 90 degrees. At this time, pull the insertion block 75 backward, then rotate the flipping frame 72 by 180 degrees, then insert the insertion block 75 back to its original position, and place the impact ball 74 into the arc-shaped shell 73. Then push the first test bench 3 and the second test bench 31 towards the middle. After pushing them to the designated position, position the positioning piece 33 on the support frame 2. Then control the adjusting screw rod 21 to rotate, and the moving block 22 will move to the upper side of the first driving block 71, and the movable contact will be positioned inside the first driving block 71. At this time, the hardness test structure 7 can be adjusted to the designated position for testing. During the test, pull the bolt 76. Under the action of gravity, the impact ball 74 will impact the side wall surface of the test roller 4 from the same height. After the impact, identify the size of the groove generated by the impact and the height of the rebound of the impact ball 74, and record them. During this period, the impact ball 74 with different gravities within a certain range can be replaced. Then control the second motor 32 to rotate to switch the angle of the test roller 4 and repeat the impact test again.

The test piece 85 includes a tail rod 851, an outer rod 855, a detection needle 858, an adjustment frame plate 852, and a lifting lead screw 854. The lifting lead screw 854 is rotatably connected inside the front side frame ring 87, and its top end extends to the outside of the front side frame ring 87 for convenient manual rotation adjustment. The tail end of the adjustment frame plate 852 is threadedly connected to the outside of the lifting lead screw 854 to adjust the position of the detection needle 858 to avoid touching during non-detection. The tail end of the adjustment frame plate 852 is limited inside the front side frame ring 87 to prevent position deviation during the lifting process. A fixing ring 856 is installed on the top surface of the adjustment frame plate 852 to limit the pressing block. The bottom end of the outer rod 855 is installed on the top surface of the fixing ring 856. The adjustment frame plate 852, the fixing ring 856, and the outer rod 855 move synchronously. The top end of the outer rod 855 is spring-connected inside the tail rod 851 to conveniently adjust the vertical distance between the detection needle 858 and the test roller 4. The top end of the tail rod 851 is fixedly installed on the inner wall surface of the front side frame ring 87. A plurality of indicator lights 853 are installed on the top end of the tail rod 851. The indicator lights 853 are multi-color display lights and are located on the outer surface of the front side frame ring 87 for convenient observation.

The upper contact ring 8554 and the lower contact ring 8553 are respectively located above and below the metal contact piece 8555. The upper contact ring 8554 is used for electrical connection with the metal contact piece 8555 when there are relatively high protrusions on the surface of the test roller 4. At this time, the corresponding indicator light 853 lights up yellow. The lower contact ring 8553 is used for electrical connection with the metal contact piece 8555 when there are relatively deep holes or grooves on the surface of the test roller 4. At this time, the corresponding indicator light 853 lights up red. When between the upper contact ring 8554 and the lower contact ring 8553, the indicator light 853 is constantly green. A limit ring 8552 is fixed on the inner wall at the bottom end of the outer rod 855 to ensure the linear movement of the active inner rod 8551. A pressing block is installed at the bottom end of the active inner rod 8551, and the pressing block is limited and connected inside the fixing ring 856.

The bottom side of the adjustment frame 852 is also connected to a card plate 857, and a magnetic block is installed on the card plate 857. The magnetic block is magnetically connected to the outer end of the adjustment frame 852. The detection needle 858 is limited in the card plate 857 to prevent the detection needle 858 from breaking and popping out during the process of lifting and lowering the adjustment frame 852.

[0025] Working principle: when the outer surface of the test roller 4 is to be inspected for defects, the two test rollers 4 are installed in the first test bench 3 and the second test bench 31 in the same manner as above, and then the rotating mechanism 6 is controlled to rotate, and the second driving block 82 is rotated to the top surface, and the moving block 22 is controlled to move, so that the moving block 22 and the second driving block 82 are connected, and then the first test bench 3 and the second test bench 31 are pushed toward the middle, and positioned by the positioning piece 33, and the moving block 22 is controlled to move to one side again, and the second driving block 82 will follow the movement, so that the plug-in rod 84 is inserted into the connecting block 83. After insertion, the positioning double rod 831 in the connecting block 83 will be connected to the limiting hole in the plug-in rod 84. At this time, the second driving block 82 and the connecting block 83 are directly fixed, and then the electromagnetic ring 35 is controlled to lose power. At this time, the moving block 22 is controlled to move forward and the detection component 81 will follow the movement. When it moves to the test roller 4, the lifting screw rod 854 is rotated, and the outer rod 855 and the adjustment frame plate 852 will move downward and remain stable under the action of the spring in the tail rod 851. When the bottom end of the detection needle 858 is connected to the outer surface of the test roller 4, the rotation stops, and then the clamping plate 857 can be removed. At this time, the metal contact piece 8555 is located between the upper contact ring 8554 and the lower contact ring 8553. At this time, the indicator light 853 shows green for normal status, and the top end of the detection needle 858 is located between the fixing ring 856 and the adjustment frame plate 852. The bottom side of the detection needle 858 has resistance and the top side has pressure so that the position can be kept stable. At this time, the test roller 4 is controlled to rotate slowly and uniformly, and the detection needle 858 will test the outer surface of the corresponding position of the test roller 4 for one circle. If the indicator light 853 shows green during the rotation, the test of this area is normal, and the moving block 22 can be controlled to move, and the test is continued at another position; If there are protrusions on the outer surface or impurities during the test, the detection needle 858 will be pushed upward, and the movable inner rod 8551 will also be pushed upward. At this time, the metal contact piece 8555 will be connected to the upper contact ring 8554, and the indicator light 853 will show yellow; When a depression or a small hole appears on the surface during the test, the detection needle 858 will sink into it, and the detection needle 858 will move downward in a small range, and the movable inner rod 8551 will also move downward in a small range. At this time, the metal contact piece 8555 will be connected to the lower contact ring 8553, and the indicator light 853 will display red; When the depth of the depression or small hole is relatively deep, the detection needle 858 will directly insert into it. At this time, the detection needle 858 will move downward over a large range until the top of the detection needle 858 breaks away from the fixed ring 856 and falls into the sliding cavity 859. At this time, the internal sensor will obtain a signal to control the device to stop. At the same time, the location of the defect can be intuitively seen directly from the position where the detection needle 858 is inserted, and it can be marked. Then, the device is reset and the test continues. After all the tests are completed, the repair treatment is carried out uniformly.

A limiting rod is installed on the inner top surface of the moving contact block 96 to prevent the synchronizing rod 962 from shifting. The top end of the synchronizing rod 962 is connected to the outside of the limiting rod. Half a test paper is glued to the bottom surfaces of the fixed contact block 95 and the moving contact blocks 96 to avoid differences in the paper.

[0027] Working principle: When performing oxidation and wear tests on the outer surface, control the rotation of the rotating rod 61 to rotate the third turntable 64 to the top surface, and then control the third motor 98 to rotate to rotate the rotating frame plate 92 to the horizontal state. At this time, control the moving block 22 to move to the top surface of the adjusting disc 91 to complete the connection between the two. Then, install the test roller 4 on the first test bench 3 and the second test bench 31, and push it to the designated position for positioning. Then, adjust the lifting block 94 downward. After the adjustment is completed, bond the two halves of the same test paper to the bottom sides of the fixed contact block 95 and the moving contact block 96 on both sides respectively. At this time, the pressing screw rod 97 can be rotated, and the cross rod 951 will move downward. The pressing piece 993 at its bottom side will press the test paper against the outer surface of the test roller 4. While the cross rod 951 is descending, its two ends will press down the synchronous rod 962 to ensure that the pressing piece 993 at the bottom side of the synchronous rod 962 also presses the test paper against the outer surface of the test roller 4. At this time, the test paper in the corresponding area is closely attached to the test roller 4. Control the test roller 4 to start rotating. After the rotation is completed, observe whether there is wear and color change on the test paper on both sides and record it. Then, control the test roller 4 to start rotating again, and at the same time control the moving block 22 to move forward, so as to realize the detection of the entire outer surface of the test roller 4, and distinguish the test results through the bottom situation of the test paper.

Move the second test bench 31 and the comparison rack 5 to the designated positions and fix them. At this time, lower the lifting block 94 and control the rotation of the gear 992. At this time, the two side driving frames 961 will extend out under the drive of the gear 992, the two side moving contact blocks 96 will move outwards, and the synchronizing rod 962 will also move outwards. Stop after moving to the designated position. Connect the test paper to the bottom sides of the moving contact block 96 and the fixed contact block 95, and rotate the pressing screw rod 97.

At this time, control the second motor 32 to rotate, and one side of the test roller 4 will rotate. Under the connection of the rotating roller, the test roller 4 on the other side will also rotate synchronously. At this time, the outer surface of the test roller 4 is in frictional contact with the test paper. After the test is completed, rotate one of the steering plates 93 by 180 degrees, raise the lifting block 94, and install the first test bench 3 at the designated position.
