[0002] As an important grinding tool, the uniformity of the abrasive layer thickness of abrasive cloth directly affects grinding efficiency, workpiece surface quality, and the service life of the abrasive cloth. In the industrial production of abrasive cloth, the abrasive layer laying is the core step that determines the quality of the abrasive layer.

This makes it difficult to adjust the thickness in time when it exceeds the tolerance, and easily leads to batches of unqualified products. Utility Model Content

[0016] In one embodiment of this utility model, such as Figure 1-7As shown, a device for real-time monitoring and adjustment of abrasive cloth thickness includes a first frame 11, a second frame 12, a lower electrode plate 21, an upper electrode plate 22, a first mounting base 31, a second mounting base 32, a high-voltage electrostatic generator, a conveyor belt 4, a drive roller 5, a first driving device, and a monitoring component 7. The second frame 12 is mounted on the first frame 11, the conveyor belt 4 is mounted on the first frame 11 and is used to convey abrasive, the drive roller 5 is rotatably mounted on the second frame 12 and is used to convey abrasive cloth base, the first driving device is used to drive the drive roller 5 to rotate, and the high-voltage electrostatic generator... The electrostatic generator is electrically connected to the lower electrode plate 21 and the upper electrode plate 22 respectively; the first mounting base 31 is mounted on the first frame 11, and the lower electrode plate 21 is mounted on the first mounting base 31. The lower electrode plate 21 is located below the conveying surface of the conveyor belt 4. The second mounting base 32 is mounted on the second frame 12, and the upper electrode plate 22 is mounted on the second mounting base 32. The upper electrode plate 22 is directly opposite the lower electrode plate 21 and is located above the conveying surface of the drive roller 5. The monitoring component 7 is used to monitor the thickness of the abrasive after it is laid, and the monitoring component 7 is electrically connected to the high-voltage electrostatic generator.In this embodiment, the high-voltage electrostatic generator is commercially available. The lower electrode plate 21 and the upper electrode plate 22 are respectively connected to the positive and negative terminals of the high-voltage electrostatic generator, thereby facilitating the formation of a high-voltage electric field between the lower electrode plate 21 and the upper electrode plate 22. The use of the conveyor belt 4 is existing technology. The conveyor belt 4 is equipped with conveyor rollers and a motor. The two conveyor rollers are rotatably mounted at the front and rear ends of the first frame 11. The two ends of the conveyor belt 4 are respectively mounted on the two conveyor rollers. The motor is correspondingly mounted on the first frame 11, and the output end of the motor is connected to the conveyor rollers, thereby driving the conveyor belt to convey abrasive. The drive roller 5 and the first... Two drive devices are provided. Two drive rollers 5 are respectively installed at the front and rear ends of the second frame 12. The two first drive devices are motors, and their output ends are respectively connected to the corresponding drive rollers 5. The abrasive cloth base is wrapped around the two drive rollers 5, and the abrasive cloth base is moved by the two drive rollers 5. Specifically, the lower electrode plate 21 is located inside the conveyor belt 4 and below the conveying surface of the conveyor belt 4, while the upper electrode plate 22 is located above the conveying surface of the drive rollers 5, facilitating the adsorption of abrasive onto the abrasive cloth base under the action of the electric field. The monitoring component 7 is located on one side of the second frame 12. Component 7 is used for real-time monitoring of the thickness of the abrasive cloth after the abrasive is laid. During operation, when the high-voltage electrostatic generator starts working, a high-voltage electric field is formed between the lower electrode plate 21 and the upper electrode plate 22. Simultaneously, the conveyor belt transports the abrasive from front to back. The first driving device drives the drive roller 5 to rotate and transport the abrasive cloth base. Under the action of the high-voltage electric field, the abrasive moves upward and adheres to the abrasive cloth base. Then, the monitoring component 7 measures the thickness of the abrasive cloth. If the measured thickness exceeds the set range, the monitoring component 7 feeds back to the high-voltage electrostatic generator. The high-voltage electrostatic generator adjusts the voltage to adjust the electric field force (thickness) between the upper electrode plate 22 and the lower electrode plate 21. When the abrasive layer is too thick, the voltage is reduced to weaken adsorption; when it is too thin, the voltage is increased to enhance adsorption, thereby achieving the purpose of real-time monitoring and adjustment. This utility model uses a first frame 11, a second frame 12, a lower electrode plate 21, an upper electrode plate 22, a first mounting base 31, a second mounting base 32, a high-voltage electrostatic generator, a conveyor belt 4, a drive roller 5, a first drive device, and a monitoring component 7 to capture the thickness of the abrasive cloth after the abrasive is laid in real time. Once it deviates from the set range, it can be directly fed back to the high-voltage electrostatic generator. By adjusting the voltage between the electrode plates, the electric field force is changed, thereby accurately controlling the amount of abrasive adsorption, ensuring that the thickness of the abrasive layer of the entire roll of abrasive cloth is uniform and consistent, and improving the product qualification rate.

[0017] like Figure 1-2 and Figure 6As shown, the monitoring component 7 includes a mounting rod 71, clamping blocks 72, a connecting seat 73, a laser sensor 74, a locking element 75, and a locking nut 76. The two clamping blocks 72 are movable up and down on the mounting rod 71, and the clamping blocks 72 can be fixed to the mounting rod 71 by the locking element 75 and the locking nut 76. One end of the connecting seat 73 is connected to the clamping blocks 72, and the other end of the connecting seat 73 is equipped with the laser sensor 74. The two laser sensors 74 are arranged opposite to each other. In this embodiment, there are two clamping blocks 72, two connecting seats 73, two laser bed holders 74, two locking components 75, and two locking nuts 76. The locking component 75 is a locking screw. During operation, the two clamping blocks 72 can be moved up and down to adjust the distance between the two laser sensors 74. After the two laser sensors 74 are adjusted, the clamping blocks 72 are clamped and fixed to the mounting rod 71 by the locking component 75 and the locking nut 76. During monitoring, based on the principle of through-beam laser sensors, the two laser sensors 74 measure the distance between the top and bottom surfaces of the abrasive cloth, respectively. The distance between the two laser sensors 74 is subtracted from the measured distance and the thickness of the abrasive cloth layout to obtain the abrasive laying thickness, which is convenient and quick.

Four guide blocks 321 are provided on the left and right sides of the second mounting base 32 to cooperate with the guide posts 122, thereby ensuring the smooth lifting and lowering of the second mounting base 32. The second drive device 81 is a motor. When working, the second drive device 81 drives the gear 82 at the output end to rotate. The rotation of the gear 82 causes the gear rail 83 to drive the second mounting base 32 to move up and down, thereby realizing the adjustment of the height position of the upper electrode plate 22. Preferably, the second drive device 81 can be electrically connected to the monitoring component 7. The monitoring component 7 can not only adjust the electric field force by adjusting the voltage of the high-voltage electrostatic generator, but also adjust the electric field force by adjusting the distance between the two electrodes through the second drive device 81, thereby obtaining a larger adjustment range and being applicable to more adjustment scenarios, achieving the effect of improving the versatility of the real-time monitoring and adjustment equipment for the abrasive cloth thickness.

[0022] like Figure 7 As shown, it also includes a third frame 92, a third drive device 93, a third mounting base 94, and a lifting airbag 95. Two third frames 92 are located on the left and right sides of the first frame 11. The left and right ends of the screen 91 are respectively mounted on the two third mounting bases 94.
