Description
Technical field
A kind of desktop level 3D printing consumptive material testing machine extrusion screw rod, belongs to 3D printing consumptive material technical field.
Background technology
Extrusion screw rod is one of main parts size on the formers such as extruder, injection machine, played in forming process to
Important effect is closed, is the conveying effect using screw rod in rotation mostly, material conveying is carried out, especially since existing spiral shell
The characteristics of self structure of bar, determines that existing extrusion screw rod is only used as the instrument of a conveying material substantially, only serves conveying
Effect, in extrusion, during high-temperature heating, material easily produces stagnation, accumulation, and material can go out
Consumptive material carbonization phenomenon is now extruded caused by temperature rises and stores up material, while reduces the cooling effectiveness of extrusion profile, is extended
Cool time, and make it that air-cooled water cooling can only be better than using cooling effect during cooling, cause water resource waste.
The content of the invention
Technical problem to be solved in the utility model is：Overcome the deficiencies in the prior art, there is provided one kind ensures that material exists
It is heated evenly in course of conveying, avoids material stock, blocks, the desktop level 3D printing consumptive material testing machine of shortening material cool time, which is used, is squeezed
Go out screw rod.
The utility model solves the technical scheme that its technical problem uses：The desktop level 3D printing consumptive material testing machine, which is used, to be squeezed
Go out screw rod, it is characterised in that：Including power intake joint, screw body and discharging termination, power intake joint and screw rod
The junction of body is provided with pan feeding boss, and the screw body of pan feeding boss side is provided with U-shaped feed well, and screw body is provided with
The thread protrusion that uniform pitch is set.
The utility model at the pan feeding boss of screw rod using U-shaped feed well is set up, by the U-shaped feed well in extruder
Material is delivered to discharge end by the screw thread for coordinating uniform pitch to set during material stirring, because screw thread uniform pitch is set, meanwhile, material
It is unified to be entered by U-shaped feed well so that material has certain buffering when entering screw rod by U-shaped mouth, will not disposably enter spiral shell
Bar causes the feed blocking of the conveying small generation in barrel internal cause space or carbonization, material uniformly can gradually be delivered to discharge end, also
Thermally equivalent of the material in course of conveying can be ensured simultaneously, avoid the occurrence of and consumptive material carbon is extruded caused by temperature rises and stores up material
Change phenomenon；Just because of material being heated evenly in course of conveying, material is more smooth in course of conveying, and the material of conveying is more
It is smooth, when being cooled down to material, can meet the needs of cooling using the type of cooling such as air-cooled, save resource and production
Cost.
Described U-shaped feed well is less than or equal to its present position perpendicular to the axially arranged of screw body, cell body depth
Screw body radius.
Described U-shaped feed well close to pan feeding boss side cell body inwall along screw body radially be vertically arranged, it is U-shaped enter
Cell body inwall of the hopper close to thread protrusion side is obliquely installed to the incline direction of thread protrusion.
The cell body inwall of U-shaped feed well is set for irregular shape, is simultaneously radially vertically arranged, and is simultaneously tilted for shelving
Set, wherein, the cell body inwall close to thread protrusion side is designed as gentle slope shape, is shaped as from charging aperture to discharging opening by steep
Slow down so that material there can be a transitional processes for buffering during thread protrusion is entered by U-shaped feed well, progressively,
Even entrance thread protrusion region, it is further to ensure to be uniformly distributed conveying in material conveying process, avoid solid accumulation very
To blocking.
The diameter of described screw body gradually increases from pan feeding boss to discharging termination direction.The diameter of screw body by
It is small to become big, it is possible to increase the extrusion force at screw body discharge end crown end, to be further ensured that the thorough output of material.
The screw diameter of gradual change, it may be such that and cooled down while material is in extrusion, with large-scale production consumptive material extruder
Equipment is compared, and improves the cooling effectiveness of extrusion profile, shortens cool time, and the desktop consumptive material testing machine after improvement can be realized
Blower fan cools down, and has broken away from the mode that large scale computer, the middle-size and small-size machine in part still use water cooling, has saved resource and cost, improve profit
With rate.
Described discharging termination is the end face of the projection that arc is set, the end face for the termination that discharges and the discharge end of screw body
Match.
Set circular arc raised in the discharge end of screw body, its effect is can be preferably bonded extrusion die, and reduction is deposited
Doses, in screw rod transmission material stirring, material is reached at the front end exit of extruder, can be by material by the design of arc-shaped
The as much as possible extrusion of property, guarantee are not in material stock phenomenon.Compared with large-scale production consumptive material extrudes machine equipment, screw rod improves
The material for being deposited in extrusion head end can be hoarded into rate afterwards reduces by 15%, while is not in be squeezed caused by temperature rises and stores up material
Go out consumptive material carbonization phenomenon.
The diameter of described power intake joint is less than the diameter of pan feeding boss.
Compared with prior art, beneficial effect possessed by the utility model is：The utility model uses entering in screw rod
U-shaped feed well is set up at material boss, the screw thread for coordinating uniform pitch to set in extruder material stirring by the U-shaped feed well will
Material is delivered to discharge end, because screw thread uniform pitch is set, meanwhile, material is unified to be entered by U-shaped feed well, and material can be uniform
Gradually be delivered to discharge end, can also ensure thermally equivalent of the material in course of conveying simultaneously, avoid the occurrence of because temperature rise
Expect caused extrusion consumptive material carbonization phenomenon with storing up；Just because of material being heated evenly in course of conveying, material was conveying
More smooth in journey, the material of conveying is more smooth, when cooling down material, can meet to cool down using the type of cooling such as air-cooled
Demand, save resource and production cost.
