Each exemplary embodiment of the present utility model is described below with reference to accompanying drawings.
Embodiment one, the utility model is a kind of screw rod of plastic extruder, and improvement part is mainly in plastic extruder
It is improved on the body of screw rod, including screw body 1, the composition of screw body 1 is axis body 2 and the flight on axis body 2
3, the screw body 1 not only plays a part of conveying at work, will also to put into the sheet of plastic extruder, diaphragm plastics
It is ground, is finally exported from the other end of screw body 1, then form strip, cooled down afterwards and cutoff process.
Therefore, screw body 1 is divided into three parts, and transportation section 4, ground section 5, deferent segment 6 are followed successively by from left to right, defeated
Section 4 is sent to be used for pushing in raw material, ground section 5 is used for being ground the plastics of sheet, diaphragm, and deferent segment 6 is used for entering clinker
Row output.
It is that the part between each flight 3 of the part of ground section 5 is to be higher by the He of transportation section 4 in the structure of original screw rod
Deferent segment 6, is mainly used to grind, and is now in the part and intensification processing is carried out to the part between each flight 3, deepens
The diameter of axis body 2 of new ground section 7 will diminish afterwards, and the mode deepened has a variety of, such as necking tool, bite etc., or
Person is said in production, is directly deepened the original screw depth of the depth ratio of the part, is eventually become new ground section 7, Ran Hou
Part welding upper stop piece 8 between each flight 3 of new ground section 7, then operated on catch 8 notch 9.
Embodiment two, on the basis of embodiment one, it is straight that the diameter after the new intensification of ground section 7 is less than the axis body 2 of ground section 5
Footpath so that can be discharged in grinding more, accelerate discharging speed, but the axis body for being greater than transportation section 4 and deferent segment 6 is straight
