The screw slenderness ratio is 29:1.
The utility model has the advantages that: arc-shaped cavity is bonded the first perpendicular rib, the size phase of the size of arc-shaped cavity and the first perpendicular rib
Mutually matching, moves up and down screw rod set, and screw rod is made to cover upper second spiral shell rib and the second perpendicular rib as screw rod set moves up and down, adjusting the
The position of two spiral shell ribs and the second perpendicular rib on screw body outer wall, since arc-shaped cavity and the first perpendicular rib are not fixed and welded together
, hush panel can be moved up and down, moves up and down the arc-shaped cavity of hush panel along the first perpendicular rib, and hush panel is moved to screw rod
The upper and lower ends of set weld together hush panel with screw rod set, while by the arc-shaped cavity position of hush panel and the first perpendicular rib, spiral shell
The body of rod welds together, and realizes that hush panel welds together with the first perpendicular rib, screw body, screw rod set is fixed on outside screw body；
The screw rod is suitable for production barrier film, nylon film, medical film, and helicitic texture design comparison is special, can prevent injection molding from producing
Contain bubble, slight crack in product.
