[0002] Vacuum roller is usually assembled by roll body, journal and other components. In the assembly process, the concentricity between components is a crucial index. Poor concentricity can cause a series of serious problems.

The outer wall of the adjusting screw 14 is provided with symmetrically distributed left-hand threads and right-hand threads. Symmetrically distributed movable blocks 15 are sleeved on the outer wall of the adjusting screw 14 and are slidably installed on the guide grooves 16. Movable plates 5 are fixedly installed on the top of the two movable blocks 15. Fixed arms 6 are fixedly installed on the upper sides of the two movable plates 5 on opposite sides. Clamps 8 are provided at the opposite ends of the two fixed arms 6.
[0035] In one embodiment, slots 22 are provided at the opposite ends of the two fixed arms 6, and a plug 19 is fixedly installed on the side of the clamp 8 near the fixed arm 6, and the plug 19 is slidably inserted into the slot 22. A positioning mechanism is provided on the fixed arm 6.
[0036] In one preferred embodiment, the positioning mechanism includes a fixing hole 21, which is located at the top of the fixing arm 6. A vertical groove 27 is provided on the inner wall of the fixing hole 21. A slide rod 26 is fixedly installed inside the vertical groove 27. A slider 24 is sleeved on the outer wall of the slide rod 26 and is slidably installed on the vertical groove 27. A spring 25 is sleeved on the outer wall of the slide rod 26 above the top of the slider 24. A positioning rod 23 is fixedly installed on one side of the slider 24 and is slidably inserted into the fixing hole 21. A pull ring 7 is fixedly installed at the top of the positioning rod 23. A positioning groove 20 is provided at the top of the insert block 19 and engages with the positioning rod 23, thereby enabling quick assembly and disassembly of the clamp 8.
[0037] In one embodiment, the slider 24 has a sliding hole that matches the slider 26, and the slider 24 is slidably connected to the slider 26 through the sliding hole.
[0038] In one preferred embodiment, the adjusting block 13 has a threaded hole that matches the threaded rod 12, and the adjusting block 13 is threadedly connected to the threaded rod 12 through the threaded hole.
[0039] In one embodiment, the movable block 15 has a threaded hole that matches the adjusting screw 14, and the movable block 15 is threadedly connected to the adjusting screw 14 through the threaded hole.
[0040] In one preferred embodiment, the inner surface of the clamp 8 is bonded with an anti-slip pad, which increases the friction with the surface of the vacuum roller, making the clamp 8 more stable when clamping the vacuum roller and preventing the vacuum roller from sliding or shifting during the testing process.
[0041] The working principle of this utility model is as follows: The entire device is controlled by controller 3. Since the device matched with controller 3 is a common device and belongs to existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described in detail here. The parts of this device not mentioned are the same as existing technology or can be implemented using existing technology. In use, the vacuum roller to be tested is placed above the laser emitter 17 and between the two clamps 8. Based on the height of the vacuum roller, the second servo motor 11 is first controlled to run. The drive end of the second servo motor 11 drives the threaded rod 12 to rotate. By utilizing the threaded transmission between the threaded rod 12 and the adjusting block 13, and the sliding cooperation between the adjusting block 13 and the slide groove 10, the adjusting block 13 is moved vertically in a stable manner, thereby driving the receiving screen 9 to move and adjusting the receiving screen 9 to a suitable height for detecting vacuum rollers of different heights. Simultaneously, the first servo motor 4 is activated, driving the adjusting screw 14 to rotate. Through the thread transmission of the left-hand and right-hand threads on the adjusting screw 14, and the sliding relationship between the movable block 15 and the guide groove 16, the two movable blocks 15 move stably relative to or in opposite directions. The movement of the movable blocks 15 drives the movable plate 5 to move, which in turn drives the clamp 8 to move via the fixed arm 6, causing the two clamps 8 to move relative to each other to clamp the vacuum roller. Then, the laser emitter 17 is activated, causing its emitted light to pass through the center hole of the vacuum roller and be directed towards the receiving screen 9 on the opposite side. If the vacuum roller is perfectly coaxial, the laser spot should fall precisely at the preset center mark on the receiving screen 9; if there is a deviation, the magnitude and direction of the eccentricity can be determined by observing the degree of deviation. This device has a high degree of automation during use, requiring no manual operation, effectively improving detection efficiency and ensuring the accuracy and reliability of the detection results.
[0042] When vacuum rollers of different outer diameters need to be inspected, the pull ring 7 can be pulled. The movement of the pull ring 7 causes the positioning rod 23 to slide within the fixing hole 21. During this process, the positioning rod 23 drives the slider 24 to slide on the outer wall of the slider 26 and compress the spring 25. As the positioning rod 23 moves upward, it disengages from the positioning groove 20 on the insert 19. At this time, the insert 19 can be pulled out from the slot 22 of the fixing arm 6, thus completing the disassembly of the clamp 8. Afterwards, to replace the clamp 8 of different specifications, the insert 19 on the clamp 8 is directly inserted into the slot 22 of the fixing arm 6. The positioning rod 23 is locked into the positioning groove 20 of the insert 19 under the elastic reset action of the spring 25, thus ensuring the stability of the clamp 8 after installation. With the detachable design of the clamp 8, the operator can easily replace the clamp 8 of different specifications to adapt to different specifications of vacuum rollers. Moreover, the detachable structure is simple, easy to operate, and facilitates quick disassembly and assembly by the operator, making it highly practical.
