On, the second zero diopter section is arranged on main paragraph, and main paragraph is arranged in the 3rd zero diopter section, and the 3rd zero diopter section is arranged on screw head post
On, screw head post is arranged on screw head, and the first zero diopter section diameter is more than the second zero diopter section, and the second zero diopter section diameter is less than main paragraph
Diameter, main paragraph are followed successively by the first spiral shell rib, perpendicular rib, horizontal rib, perpendicular rib and the second spiral shell rib, two groups are set outside main paragraph from top to bottom outside
Perpendicular rib, every group of perpendicular rib quantity more than one, erect rib outer surface and multiple first steel balls are installed, four horizontal ribs are set outside main paragraph, the
Three zero diopter section diameters are less than main paragraph diameter, and screw head column diameter is less than the 3rd zero diopter section diameter, and screw head post front and rear sides are respectively installed
Four the second steel balls.
The screw head is conical structure.
The screw column is cylindrical structure.
The utility model has the advantages that：It is rapider that first spiral shell rib makes material elapse forward；Two groups of perpendicular ribs and the first steel
Ball can make mixing process adequacy, uniformity more preferably, and product quality is high, does not have bubble；Material pushes away forward with the second spiral shell rib
Enter, accelerate the discharging of material；The stepped structure declined is presented in main paragraph, the 3rd zero diopter section and screw head column diameter so that discharging
It is more rapid, while the second steel ball can play a part of friction to material and promote, the bubble in material is arranged during discharging
Go out, screw head has the function of removing bubble, and the spiral shell rib of this type nitride screw rod is complicated various, can improve plastic material
It is kneaded.
