[0035] Reference Figure 3-Figure 5 The rotating shaft 82 passes through and is rotatably connected to the left surface of the slider 74. The rotating shaft 82 and the slider 74 will move synchronously. The slot 801 is opened in a trapezoidal shape, with the opening larger at the top and smaller at the bottom. A threaded groove is opened on the left surface of the mounting ear 83. The left and right surfaces of the cleaning roller 84 are both provided with threaded grooves.

The starting motor 81 can drive the rotating shaft 82 to rotate. The left surface of the block 86 is set to an arc surface. When the arc surface of the block 86 is squeezed, the block 86 will move to the right and retract into the rotating shaft 82. The block 86 is inserted into the inner wall of the slot 802. One end of the compression spring 87 is fixedly connected to the right surface of the block 86, and the other end of the compression spring 87 is fixedly connected to the inner wall on the right side of the rotating shaft 82. When the block 86 moves to the right, it will squeeze the compression spring 87 to generate a reaction force. The block 86 passes through and is slidably connected to the left surface of the rotating shaft 82.

[0036] Working principle: When using this device, first adjust the gear position of the constant force device 4 according to the needs of processing hot-dip galvanized plates, and then adjust the height of the cleaning roller 84 according to the thickness of the hot-dip galvanized plates. When adjusting, grasp the handwheel 73 to drive the threaded rod 72 to rotate, and then drive the handwheel 73, threaded rod 72 and slider 74 to move longitudinally. When the slider 74 moves longitudinally, it will drive the rotating shaft 82, motor 81, and cleaning roller 84 to move longitudinally, so that the height of the cleaning roller 84 can be flexibly adjusted. When the height is adjusted to the appropriate height, release the handwheel 73. The device will remain stable due to the self-locking property of the threaded rod 72. Then place the hot-dip galvanized plate on the support table 1, and start the robotic arm 5 and the grinding disc 6 to grind the hot-dip galvanized plate.

[0037] During the grinding process, the hot-dip galvanized plate can be moved backward, and the impurities and dust generated by grinding will also move backward with the hot-dip galvanized plate. When the dust and impurities move to the cleaning roller 84, the motor 81 and the dust suction device 3 are started. After the motor 81 is started, it will drive the rotating shaft 82 and the cleaning roller 84 to rotate. The rotating cleaning roller 84 will sweep away the dust and impurities. The dust suction device 3 can absorb the dust and impurities and collect them. After the grinding is completed, the robotic arm 5, the grinding disc 6, the dust suction device 3 and the motor 81 can be turned off.

[0038] If the cleaning roller 84 needs to be replaced, first rotate the cleaning roller 84 to drive the rotating shaft 82 to rotate so that the end with the larger opening of the slot 801 faces upward, then unscrew the bolt, and then pull the cleaning roller 84 and the insert block 85 upward. When pulling, the arc surface of the block 86 will be squeezed, and the block 86 will retract into the rotating shaft 82 and disengage from the slot 802 to release the limit on the insert block 85. After the cleaning roller 84 and the insert block 85 are disassembled, take out the new cleaning roller 84 and the insert block 85 and align the insert block 85 with the slot 801 and move it downward. The downward moving insert block 85 will squeeze the arc surface of the block 86, and the block 86 will retract into the rotating shaft 82 to release the obstruction and squeeze the compression spring 87 to generate a reaction force. When the plug-in block 85 and the slot 801 are plugged in, they will not be able to move downward. At this time, the block 86 will also be aligned with the slot 802. Under the push of the reaction force of the compression spring 87, the block 86 will be plugged into the slot 802 to preliminarily limit the position of the block 85 and the cleaning roller 84, and then the threaded hole of the mounting ear 83 will be aligned with the threaded hole on the cleaning roller 84, and fixed with bolts to complete the installation.
