Embodiment Construction

[0021] Such as figure 1 The mold of the forming equipment of the hollow filter rod has a shell mold 3 and a core mold 8 located at the center of the shell mold 3, and also has a steam source connected to the shell mold 3 and the inner cavity of the core mold 8 respectively. Pipeline 2; the main part of the inner wall of the shell mold 3 is a cylindrical shape, and the inner wall has a length of 40-50 cm and is distributed with numerous shell steam holes 4; the main part of the outer wall of the mandrel 8 is a cylindrical shape. The outer wall has a section with a length of 30-35cm and numerous core steam holes 9 distributed therein.

[0022] The number of shell steam holes 4 and core steam holes 9 is moderate, so that the injection amount of steam can meet the heating and bonding requirements of triacetin and cellulose acetate tow in the filter element, and is not saturated. The diameter of each shell steam hole 4 is 0.3-0.6mm, and the size of the core steam hole 9 is not lar...
