Abstract
A kind of plastic extruder pressing mechanism is the utility model is related to, includes barrel and screw rod, it is characterised in that：Described barrel one end is feed zone, the other end is discharging section, the screw rod is provided with feed zone with the use of the pressing mechanism that can fully extrude raw material in barrel with feed zone correspondence position, the discharging section is provided with the plastifying organization that can be plastified to high/low temperature impurity, using above-mentioned technical proposal, the vapor in raw material can be distributed in the air discharge duct that feed zone is set, squeezing effect and plasticizing effect are improved, and sets air discharge duct can be by the cleaner of the vapor row in raw material on barrel.
Description
Technical field
It the utility model is related to plastic extruder accessories field, and in particular to a kind of plastic extruder pressing mechanism.
Background technology
The main frame of plastic extruder is extruding machine, and it is made up of extrusion system, transmission system and heating and cooling system, extruding
System includes screw rod, machine barrel（Also referred to as barrel）, hopper, head and mould, plastics plastified into by extrusion system it is uniform molten
Body, and in this course under established pressure, by the continuous extruder head of screw rod, screw rod is the main portion of plastic extruder
Part, it is directly connected to the application and survival rate of extruder, and it coordinates practicality with barrel, realizes the crushing to plastics, soft
To change, melting, plasticizing, exhaust and compacting, and sizing material is conveyed to formation system continuous uniform, barrel is a cylinder type hollow column,
The external diameter of its internal diameter and screw rod matches to realize mating reaction, but traditional barrel is flat configuration inside it, and screw rod
Screw thread is provided with discharging due to raw material, generally all can be in the certain impurity of barrel Inner extrusion, it is often necessary to
Barrel is cleaned, and the raw material not exclusively extruded are often left between screw rod and traditional barrel, is discharged after extruding inefficient,
Cause production efficiency low.
Utility model content
Technical problem to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art,
A kind of plastic extruder pressing mechanism is provided.
To achieve the above object, the utility model provides following technical scheme：A kind of plastic extruder pressing mechanism, bag
Include barrel and screw rod, it is characterised in that：Described barrel one end is feed zone, and the other end is discharging section, and the screw rod is with entering
Material section correspondence position is provided with the pressing mechanism for being used cooperatively with feed zone and can fully extruding raw material in barrel, and the discharging section is set
There is the plastifying organization that can be plastified to high/low temperature impurity.
Using above-mentioned technical proposal, the plastifying organization that the pressing mechanism that feed zone is set is set with discharge end can play by
The effect with fully plastifying fully is extruded into the raw material in the barrel, and its interior smooth of traditional barrel is only leaned on and barrel
Thread groove on the screw rod of cooperation is extruded and plastified, and its extruding is unsatisfactory with plasticizing effect.
A kind of above-mentioned plastic extruder pressing mechanism can be further arranged to：The pressing mechanism includes in feed zone
The groove in continuous arc spiral distribution that wall is set, the screw rod are provided with inverse-arc shape helical form point in opposite position
The projection of cloth, the plastifying organization are at least one extruding groove being twist distributed that discharging section inwall is set.
Using above-mentioned technical proposal, in the groove in continuous arc spiral distribution that feed zone inwall is set, it has
Certain depth, and the projection of its inverse-arc shape spiral distribution set with screw rod in this section is a positive and a negative being used cooperatively
Set, the principle of similar row screw rod, by the cooperation of positive arc helical groove and inverse-arc shape spiral salient by raw material
Fully extruding, it will can then treat to enter by the material of discharging section out in the extruding groove being twist distributed that discharging section inwall is set
Row fully plasticizing, and extruding groove is twist distributed, in opposite direction with screw flight, the utility model is set in discharging section
Extruding groove can play a part of improving plasticizing effect, and high/low temperature impurity material can be carried out plastifying, like the principle of flour mill.
A kind of above-mentioned plastic extruder pressing mechanism can be further arranged to：The feed zone is additionally provided with air discharge duct, institute
It is the circular hole being arranged on the inwall of feed zone side to state air discharge duct.
Using above-mentioned technical proposal, the vapor in raw material can be distributed in the air discharge duct that feed zone is set,
Squeezing effect and plasticizing effect are improved, and sets air discharge duct can be by the cleaner of the vapor row in raw material on barrel.
The beneficial effects of the utility model are：Squeezing effect is more perfect, and plasticizing effect becomes apparent from, and the air discharge duct of setting can be with
Raw material are subjected to further hydrofuge.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 is the schematic perspective view of the utility model embodiment.
Fig. 2 is the screw-rod structure schematic diagram of the utility model embodiment.
Fig. 3 is the sectional view of the utility model embodiment barrel.
Embodiment
Referring to shown in Fig. 1-Fig. 3：A kind of plastic extruder pressing mechanism, includes barrel 1 and screw rod 2, and the one end of barrel 1 is
Feed zone 11, the other end are discharging section 12, and screw rod 2 is provided with feed zone 11 with the use of can fill with the correspondence position of feed zone 11
Dividing the pressing mechanism of raw material in extruding barrel 1, discharging section 12 is provided with the plastifying organization that can be plastified to high/low temperature impurity,
Pressing mechanism includes the groove 111 in continuous arc spiral distribution of the inwall of feed zone 11 setting, and screw rod 2 is corresponding
Position is provided with the projection 21 of inverse-arc shape spiral distribution, and plastifying organization is twist being distributed for the inwall of discharging section 12 setting
At least one extruding groove 121, feed zone 11 are additionally provided with air discharge duct 112, and air discharge duct 112 is to be arranged on the side inwall of feed zone 11
Circular hole.
