[0001] The application belongs to the technical field of carbon fiber production, and particularly relates to a PAN precursor non-contact transfer tool. BACKGROUND

[0002] PAN precursor is an important raw material for producing carbon fiber, and its quality needs to be ensured during production and transportation. At present, PAN precursor is usually wound on a winding drum for transfer during long-distance transportation, but the existing transfer device has many problems.

At the same time, the existing transfer tool structure is not stable enough, and is inconvenient to load and unload, which is difficult to meet the needs of large-scale and long-distance transportation. Therefore, there is an urgent need for a tool that can stably fix the winding drum and prevent the PAN precursor from being damaged during long-distance transportation. SUMMARY
