The disk (24) is rotated 90 degrees, so that the limiting plate (23) can limit the limiting frame (15). When the graphite felt passes through the mounting frame (14), the turntable (24) is rotated to align the limiting plate (23) with the rotating rod (22), and the mounting frame (14) is released. At this time, the spring 1 (20) will extend and push the limiting frame (15) to move downward, so that the limiting frame (15) is attached to the top of the graphite felt to limit the graphite felt. At this time, the motor 2 (13) is started to continuously transport the graphite felt.

3. After the graphite felt coil is sleeved on the surface of the material placement rod (27), the second limiting ring (36) is threadedly connected to the sliding sleeve (34), and then the sliding sleeve (34) is sleeved on the surface of the material placement rod (27), and the second limiting ring (36) is fitted with the graphite felt coil. The torsion block (38) is rotated to make the threaded rod (37) and the sliding sleeve (34) threadably move, so that the threaded rod (37) and the surface of the material placement rod (27) are fitted, and then the second limiting ring (36) limits the graphite felt coil, and the pulling block (33) is pulled to make the fixing ring (31) The second spring (32) is squeezed to make the second spring (32) contract. When the fixing rod (30) enters the inner cavity of the fixing sleeve (29), the material placement rod (27) is placed into the inner cavity of the installation opening (26), and the pulling block (33) is released to make the second spring (32) extend. The second spring (32) pushes the fixing rod (30) into the inner cavity of the fixing hole (28) through the fixing ring (31), thereby making the fixing rod (30) fix the material placement rod (27). At this time, the graphite felt can be transported by pulling the material head on the surface of the graphite felt coil.
