Abstract
PE pipe extruder screws are regenerated the utility model discloses one kind, it is characterised in that：Including screw body, screw thread in the middle of the screw body includes some positive clockwise thread segments and reverse anticlockwise thread segment, positive clockwise thread segment and reversely anticlockwise thread segment interval setting, the pitch of positive clockwise thread segment is bigger than the pitch of reverse anticlockwise thread segment, is provided with groove on the spiral shell of positive clockwise thread segment and reverse anticlockwise thread segment is stupefied.Positive clockwise thread segment of the present utility model can make raw material forward flow, groove on positive clockwise thread segment spiral shell is stupefied can make a small amount of raw material reverse reflux, reverse anticlockwise thread segment can make part material reverse reflux, groove on reverse anticlockwise thread segment spiral shell is stupefied can make a small amount of raw material forward flow, it ensure that raw material is well mixed, it is ensured that the quality of product.
Description
Technical field
The utility model is related to a kind of regeneration PE pipe extruder screws, belongs to machining equipment field.
Background technology
Because PE has good corrosion resistance, good pliability and impact resistance, long lifespan, safe and reliable form of construction work
The advantages of, therefore it is quite extensive using scope, and gas piping, natural gas pipe, blow-off line, change are mainly used at present
Conveying of the factory such as work, pharmacy, papermaking feed liquid etc..The country is quickly grown using PE tubing, and annual average rate of increase is 18-20%, is cut
To the end of the year 2014, domestic annual special material for tube is consumed up to 1,500,000 tons or so.Traditional PE can be caused to environment into dirt
Dye, therefore turn into current main flow now with regeneration PE production pipelines.When traditional extruder production regenerates PE pipes, extruder
Screw rod be only that compound from end is entered is delivered to extruding end, it is easy to cause raw material mixing uneven, influence product quality.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of regeneration PE pipe extruder screws.
In order to achieve the above object, the technical scheme that the utility model is used is：
The screw thread regenerated in the middle of PE pipe extruder screws, including screw body, the screw body is suitable including some forward directions
Conterclockwise thread segment and reverse anticlockwise thread segment, reversely positive clockwise thread segment and side counterclockwise
To thread segment be arranged at intervals, the pitch of the pitch of positive clockwise thread segment than reverse anticlockwise thread segment
Greatly, the spiral shell of positive clockwise thread segment and reverse anticlockwise thread segment it is stupefied on be provided with groove.
The screw thread at the screw body two ends is positive clockwise thread segment.
Positive clockwise screw thread segment length is more than reverse anticlockwise reach.
The central shaft of the texturearunaperpendicular screw rod is opened up.
The groove be evenly distributed on spiral shell it is stupefied on.
The groove is arc groove.
The beneficial effect that the utility model is reached：Positive clockwise thread segment of the present utility model can make original
Expect forward flow, the groove on positive clockwise thread segment spiral shell is stupefied can make a small amount of raw material reverse reflux, reverse inverse time
The thread segment in pin direction can make part material reverse reflux, and the groove on reverse anticlockwise thread segment spiral shell is stupefied can make
A small amount of raw material forward flow, it is ensured that raw material is well mixed, it is ensured that the quality of product.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As shown in figure 1, regeneration PE pipe extruder screws, including screw body, the screw thread at screw body two ends is forward direction
Screw thread in the middle of clockwise thread segment, screw body includes some positive clockwise thread segments and reverse inverse time
The thread segment in pin direction, middle positive clockwise screw thread segment length is more than reverse anticlockwise reach,
Positive clockwise thread segment and reversely anticlockwise thread segment interval setting, positive clockwise thread segment
Pitch it is bigger than the pitch of reverse anticlockwise thread segment, positive clockwise thread segment and reversely counterclockwise
Thread segment spiral shell it is stupefied on be provided with groove, the central shaft of texturearunaperpendicular screw rod is opened up, groove be evenly distributed on spiral shell it is stupefied on, it is recessed
Groove is arc groove.
The positive clockwise thread segment of above-mentioned screw rod can make raw material forward flow, positive clockwise spiral shell
Groove on line section spiral shell is stupefied can make a small amount of raw material reverse reflux, and reverse anticlockwise thread segment can make part material anti-
To backflow, the groove on reverse anticlockwise thread segment spiral shell is stupefied can make a small amount of raw material forward flow, it is ensured that raw material is mixed
Close uniform, it is ensured that the quality of product.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and deformation can also be made, these change
Enter and deform and also should be regarded as protection domain of the present utility model.
