Specific embodiment
For the present invention aforementioned and other technology contents, feature and effect, in following cooperation with reference to figures 1 through Fig. 2 pair
In the detailed description of embodiment, clearly can present.The structure content being previously mentioned in following examples, is attached with description
Figure is reference.
Each exemplary embodiment of the present invention is described below with reference to accompanying drawings.
Embodiment one, the present invention are a kind of screw rod of plastic extruder, and improvement part is mainly in the screw rod of plastic extruder
Body on be improved, including screw body 1, the composition of screw body 1 is axis body 2 and the flight on axis body 23, should
Screw body 1 not only plays a part of conveying at work, will also carry out to putting into the lamellar of plastic extruder, the plastics of diaphragm
Grinding, finally exports from the other end of screw body 1, then forms strip, is cooled down afterwards and cut-out is processed.
Therefore, screw body 1 is divided into three parts, is followed successively by transportation section 4, ground section 5, deferent segment 6 from left to right, defeated
Section 4 is sent for raw material are pushed, for being ground to the plastics of lamellar, diaphragm, deferent segment 6 is for entering to grog for ground section 5
Row output.
It is that the part between each flight 3 of 5 part of ground section is to be higher by 4 He of transportation section in the structure of original screw rod
Deferent segment 6, is mainly used to grind, and being now in the part carries out intensification process to the part between each flight 3, deepens
2 diameter of axis body of new ground section 7 will diminish afterwards, and the mode deepened has various, such as necking tool, cutting edge etc., or
Person says in production, directly deepens the depth ratio of the part original screw depth, eventually become new ground section 7, Ran Hou
Part welding upper stop piece 8 between each flight 3 of new ground section 7, then notch 9 has been operated on catch 8.
Embodiment two, on the basis of embodiment one, it is straight that the diameter after the intensification of new ground section 7 is less than 5 axis body 2 of ground section
Footpath so that can discharge in grinding more, accelerate discharging speed, but the axis body for being greater than transportation section 4 and deferent segment 6 is straight
Footpath, it is therefore an objective to retain original means of abrasion, if identical with transportation section 4 and 6 diameter of deferent segment, then grinding effect will become
