[0033] Reference Figure 2 and Figure 6The lower roller quick positioning and assembly structure also includes a coupling 7, which is fixedly arranged on the side of the first mounting flange 3 away from the roller body 8, and one side of the coupling 7 penetrates into the first mounting flange 3. The coupling 7 is provided with a connecting portion 71 and a fixing portion 72, the connecting portion 71 is located in the first mounting portion, the fixing portion 72 is detachably fixed to the connecting portion 71, and the roller shaft end of the roller body 8 is tightly matched with the fixing portion 72 and the inner wall of the connecting portion 71. The end of the roller body 8 is connected with a flat key 81. Specifically, a key slot 82 is provided at the end of the roller shaft of the roller body 8.

[0038] First, remove the fasteners between the first positioning flange 4 and the first mounting flange 3, and between the second positioning flange 6 and the second mounting flange 5, and remove the first positioning flange 4 and the second positioning flange 6; then remove the fasteners between the fixing portion 72 and the connecting portion 71, and remove the fixing portion 72. At this time, the roller body 8 is in a removable state, and the roller body 8 is hoisted by the fixing tool; then remove the flat key 81 and the retaining rings on both sides of the roller body 8, and the bearing 83 can be replaced; after replacing the new bearing 83, assemble the roller body 8 in place in the reverse order of disassembly, and the disassembly and replacement action is completed. Since the first mounting flange 3, the second mounting flange 5 and the coupling 7 are not removed when replacing the bearing 83, the reassembled roller body 8 can also maintain the original horizontal state and remain parallel to the adjacent roller body 8, and the sealing of the structure can be ensured, and there is no need to adjust the level and leak check the installed roller body 8, which effectively reduces the difficulty of disassembly and simplifies the disassembly and assembly process, and can quickly realize the replacement of the bearing 83.
