[0002] The mica tape wrapping machine for fire-resistant cables is a type of equipment specifically used to produce fire-resistant cables. It is usually used to wrap mica tape (a material that is resistant to high temperatures and has good insulation properties) around the cable conductor to enhance the cable's fire resistance and insulation properties. This wrapping machine has automated functions that enable efficient production and usually has an adjustment function to accommodate the production of fire-resistant cables of different specifications and requirements.

[0003] In the prior art, most wrapping machines directly fix the mica tape through a bearing seat and a fixing frame and then use a motor to drive it to rotate for wrapping.
