[0060] In an exemplary embodiment, the roller shaft disassembly and assembly equipment further includes a fixing device 5. The fixing device 5 can abut against the roller 10 to fix the roller 10 to the frame 1.

[0061] In this embodiment, by fixing the roller 10 to the frame 1 with the fixing device 5, the shaking during the disassembly and assembly of the fastener 30 can be reduced. Among them, the fixing device 5 can be, for example, an elbow clamp, and its specific structure can adopt the relevant structures in the prior art and will not be elaborated here. Since the graphite roller is more brittle than materials such as metal pipes, in order to avoid the wear of the elbow clamp on the graphite roller during clamping and improve the clamping stability, when using the elbow clamp to fix the graphite roller, the relative height between the clamping head of the elbow clamp and the graphite roller can be adjusted by providing a padding block on the frame 1, and the relative position between the elbow clamp and the graphite roller can be adjusted so that the clamping head of the elbow clamp can clamp the middle part of the roller 10 of the graphite roller.

[0066] Wherein, the frame 1 further includes a chassis 13 and two first support plates 14 located at both ends of the chassis 13. Two first rectangular tubes 15 are arranged between the two first support plates 14. A switching bottom plate 16 is arranged on the tops of the two first rectangular tubes 15.

The support block 11 is arranged on the third rectangular tube 19. Through the above frame 1 structure, the stability of the overall structure of the roller shaft disassembly and assembly equipment can be improved.

[0067] In an exemplary embodiment of the present application, a working process of a roller shaft disassembly and assembly equipment is provided. For the convenience of description, in this embodiment, the workpiece 100 is taken as a graphite roller and the fastener 30 is taken as a nut for illustration.

[0068] Place the graphite roller on the frame 1, support the roller 10 through the support block 11, support the graphite roller through the accommodation groove 12, and fix the roller 10 through the fixing device 5; Start the switching device 4, drive the sliding structure 41 to move through the third driving mechanism 42 to adjust the relative position between the sleeve 21 located on the sliding structure 41 and the graphite roller, so that the axis of the sleeve 21 coincides with the axis of the roller shaft 20; Drive the support structure 221 to move towards the nut through the second driving mechanism 25, so that the sleeve 21 is sleeved on the nut; Drive the sleeve 21 to rotate through the first driving mechanism 22, and at the same time drive the support structure 221 to move away from the nut through the second driving mechanism 25 to disassemble the nut and separate it from the roller shaft 20. Then drive the sliding structure 41 to move through the third driving mechanism 42 to adjust the relative position between the ejector device 3 located on the sliding structure 41 and the graphite roller, so that the axis of the push rod of the ejector device 3 coincides with the axis of the roller shaft 20; Start the ejector device 3 to eject the roller shaft 20 from the roller 10 to realize the separation of the roller shaft 20 and the roller 10; In this way, the disassembly work of the old roller 10 is completed.

[0069] When a new roller 10 needs to be installed on the roller shaft 20, place the new roller 10 on the frame 1 and fix the roller 10 through the fixing device 5; Adjust the relative position between the ejector device 3 located on the sliding structure 41 and the graphite roller through the switching device 4, so that the axis of the push rod of the ejector device 3 coincides with the axis of the roller shaft 20; Install the roller shaft 20 on the ejector device 3, and push the roller shaft 20 into the roller 10 through the push rod of the ejector device 3; Then adjust the relative position between the sleeve 21 located on the sliding structure 41 and the graphite roller through the switching device 4, so that the axis of the sleeve 21 coincides with the axis of the roller shaft 20, place the nut on the sleeve 21, drive the support structure 221 to move towards the nut through the second driving mechanism 25, and drive the sleeve 21 to rotate in the opposite direction through the first driving mechanism 22 to install the nut on the roller shaft 20 and make the nut abut against the end of the roller 10 to realize the assembly of the roller shaft 20 and the roller 10.

[0070] In summary, through the roller shaft disassembly and assembly equipment of the present application, the disassembly and installation of the roller shaft 20 of the graphite roller can be realized, effectively solving the problems of complex installation process, long time consumption, and poor installation quality of the graphite roller. The roller shaft disassembly and assembly equipment can replace manual operation, which can not only reduce the labor intensity of workers, improve the replacement efficiency of accessories, but also reduce the labor cost; Moreover, it can also avoid direct disassembly and assembly by operators, which helps to improve the operation safety; In addition, through the high-precision disassembly and assembly of the roller shaft disassembly and assembly equipment, damage to the graphite roller can be effectively avoided, resulting in scrapping, significantly improving the quality of the graphite roller after disassembly and assembly, extending the service life of the graphite roller, and reducing costs.
