When the plastic film is processed, the reduction motor I is started, and the output shaft of the reduction motor I drives the feeding shaft 23 to rotate, thereby releasing the mesh coil on the feeding shaft 23, and the released mesh coil passes through the auxiliary material hole 22 and is output from the lower part of the forming frame 21. During the transportation of the mesh coil, the material extruded in the forming frame 21 is coated on the outside of the mesh coil, thereby realizing the forming of the plastic film.
