Description
Technical field
The utility model relates to plastic extrusion machinery field, relates in particular to a kind of machine head port mould adjusting bolt of plastic extruder.
Background technology
Plastic pipe is as the important component part of chemical building material, with physical and mechanical properties such as its superior corrosion-resistant, rigidity, toughness, shock resistances, health, environmental protection, low consumption etc., by users are accepted extensively, are widely used in the fields such as building, water conservancy, municipal works.Duct products in continuous expansion, has become the product of being extensively familiar with being seen everywhere from the market of plastic conduit, and plastic conduit product receives the concern of every aspect.The production of plastic conduit relies on plastic extruder, and cross-head mould determines one of key factor of pipe workpiece quality.The quality that the inclined to one side extent of tube wall thickness not only affects tubing also can cause the rising of raw materials for production cost.And the control of tubing production wall thickness deviation is mainly the adjustment that realizes plug and mouthful die clearance by the adjustment screw of machine head port mould outside.
At present, by hexagonal adjustment screw in conventional, the wall thickness deviation of plastic pipe cannot be completed wall thickness deviation is controlled more accurately, and complex operation, need to repeatedly adjust the dimensional requirement that could meet tubing, produce a large amount of processing waste products.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of machine head port mould adjusting bolt of plastic extruder of effective control tubing wall thickness deviation.
For addressing the above problem, the machine head port mould adjusting bolt of a kind of plastic extruder described in the utility model, comprise fixed sleeving, be the bolt of interior hexagonal and cover and have the screw of spring, it is characterized in that: described bolt head is provided with annular boss, and stretch in described fixed sleeving; The periphery of described annular boss is provided with the circular orbit being parallel to each other
, circular orbit
, this circular orbit
with circular orbit
between spacer region be symmetrically distributed with three through holes; In a through hole in described three through holes, be provided with spherical roller
, in all the other two through holes, be provided with spherical roller
; Described screw be placed in a through hole of described three through holes and with described spherical roller
join; Described annular boss end is provided with location baffle ring, and this location baffle ring joins by location jump ring and described fixed sleeving end.
The excircle of described bolt is provided with trapezoidal coarse thread, and the screw thread that the inner periphery of this trapezoidal coarse thread and described fixed sleeving is provided with matches.
On the inner periphery of described fixed muffle and the excircle of described bolt, be equipped with graduation mark.
The utility model compared with prior art has the following advantages:
1,, because the excircle of bolt in the utility model is provided with trapezoidal coarse thread, the screw thread that the inner periphery of this trapezoidal coarse thread and fixed sleeving is provided with matches, and the periphery of bolt head annular boss is provided with the circular orbit being parallel to each other
, circular orbit
utilize screw principle can realize to plug and mouthful die clearance compared with fine adjustment, thereby complete the accurate control to tube wall thickness, reach the rapid adjustment to tube wall thickness deviation in process of production, reduce the object that waste product produces, saves raw materials for production cost.
2, the utility model is simple in structure, practical.

Detailed description of the invention
A machine head port mould adjusting bolt for plastic extruder, comprises fixed sleeving 1, is the bolt 11 of interior hexagonal and overlaps the screw 6 that has spring 7.
Bolt 11 heads are provided with annular boss, and stretch in fixed sleeving 1; The periphery of annular boss is provided with the circular orbit being parallel to each other
4, circular orbit
12, this circular orbit
4 and circular orbit
spacer region between 12 is symmetrically distributed with three through holes 5; In a through hole in three through holes 5, be provided with spherical roller
8, in all the other two through holes, be provided with spherical roller
10; Screw 6 is placed in a through hole of three through holes 5 and and spherical roller
8 join, with the face composition Auxiliary Track 9 of the annular boss circumference of bolt 11 heads; Annular boss end is provided with location baffle ring 3, and this location baffle ring 3 joins with fixed sleeving 1 end by location jump ring 2.
Wherein: the excircle of bolt 11 is provided with trapezoidal coarse thread, the screw thread that the inner periphery of this trapezoidal coarse thread and fixed sleeving 1 is provided with matches.
On the excircle of the inner periphery of fixed muffle 1 and bolt 11, be equipped with graduation mark.This graduation mark is n equal portions by circumference equal dividing, and according to screw principle, when bolt 11 rotates a circle, bolt 11 advances or a slow astern pitch--P millimeter.Like this, bolt 11 rotates after a calibration relative to dial, and it has turned over 1/n week, and at this moment screw rod has moved 1/n × P millimeter=P/n millimeter along axis, i.e. the degree of depth of bolt precession mouth mould is P/n mm.
When use, in plastic extruder mouth die mandrel installation process, will reconcile in advance screw 6 precession mouth mould adjustment holes 13, and keep concordant with mouth mould inner surface; Then use the gap between kind of calliper mouth mould and plug, after the gap between mouth mould and plug being adjusted to always as far as possible by the screw-in/back-out of adjusting bolt 11, the utility model is adjusted to plug and is contacted, plug and the distance of mouthful mould are fixed.Until charging barrel of plastic extruder and mold temperature reach be incubated 30 minutes after setting after start produce.Measure tubing wall thickness deviation, if the deviation of tube wall thickness not within standard prescribed limit, regulates the conciliation bolt 11 of the corresponding wall thickness deviation of tubing position, until tube wall thickness deviation meets standard-required.
