The bubble impurity on material surface layer is assisted in removing, the single thread tooth mouth element is arranged at the beginning section of the screw rod, as material
The starting point of transfer, wide thread mouth element are transported, the width thread mouth element one side is adjacent to the single thread tooth
Mouth element, opposite side engage with building block type tooth lobe mouth elements into intimate and are arranged at the middle position of the screw rod, and spine tooth is dashed forward
Tooth mouth element, the spine tooth lobe mouth element, which links closely, is connected to the building block type tooth lobe mouth element.
Further, the single thread tooth mouth element is respectively arranged at the feeding mouth of the twin-screw of plastic granulator and goes out
Material mouth, the structure of single screw thread realize the progradation of material under twin-screw uniform rotation as unique motive power.
Further, the screw thread of the wide thread mouth element is at intervals of 3cm, be conducive to material be heated evenly and
Material can be improved and participate in modified actually active ratio.
Further, the building block type tooth lobe mouth element engagement splicing angle can by 30 °, 45 °, 60 ° or
90 ° are made adjustment, and are conducive to more fully dissipate the reality for mixing and improving material participation modification when material is modified mixing
Effective ratio.
Further, during its unique spine type structure of the spine tooth lobe mouth element can poke material production
The blibbing of generation excludes the bubble impurity interference of material.
The beneficial effects of the utility model are：A kind of twin-screw engagement knot of the plastics-production equipment of the utility model
Structure, wherein the screw rod, the single thread tooth mouth element, the wide thread mouth element, building block type tooth lobe mouth member
Part realizes the function that the conveying in material production is shifted, is fully heated and is modified closer to desired proportions；The spine
Tooth lobe mouth element then realizes the function of excluding the interference of surface of material bubble impurity, reduces screw rod because producing for a long time
The abrasion gradually generated in journey, more practical rational device structure meet enterprise and plant maintenance are innovated and reduced to self-technique
Caused pressure improves the demand that production cost is produced and reduced for high-quality finished product.
