It will appear the problem of influencing printed product appearance when particulate material, i.e., still have material from print head in the place for not needing printing
Nozzle at flow out, fall on the product printed.The self weight of material in the molten state is primarily due to cause, and
Existing print head structure not can solve material because caused by self weight the problem of this influence printing appearance.
Summary of the invention
The problem of will appear material leakage the present invention overcomes the print head of FDM printer in the prior art, provide a kind of spiral shell
The print head for revolving structure, solves the problems, such as material leakage of the print head of existing FDM printer when printing particulate material.
The technical scheme is that
A kind of print head applied to FDM printer, it is characterised in that: the print head of FDM printer includes spirally beating
It prints head (1)；The scroll print head (1) includes squeezing out shell (2) and rifle bar (3)；The rifle bar (3) is inserted in extrusion
In shell (2).
Further, the extrusion shell (2) includes hollow cylindrical part and hollow frusto-conical portion.
Further, the rifle bar (3) is inserted in the column part for squeezing out shell (2), and the periphery of rifle bar (3)
Shell (2) inner wall is closely coupled with squeezing out.
It further, is top-down helicla flute inside the rifle bar (3).
Further, the helicla flute and the angle of horizontal direction are less than 10 degree.
Further, the high-temperature material that the rifle bar is resistance to 400 degree or more.
Further, the spiral groove surface roughness of the rifle bar is between 3.2-25.
Compared with prior art, beneficial effects of the present invention are as follows:
The present invention passes through the self weight of equalizing molten material, provides a kind of print head of helical structure, not only solves existing
Have FDM and 3D printer when printing particulate material the problem of one direct current material, and solve with FDM and 3D printer printing
The bad defects such as the coarse, wire drawing of product surface.Scroll print head of the invention can be saved effectively in printing portion product
The process for going printing post-processing, improves FDM and 3D printer printing effect.It is also printed simultaneously because of FDM and 3D printer
Product has better surface quality and can be applied to more areas, has expanded the market demand of FDM and 3D printer.
Detailed description of the invention
Fig. 1 is scroll print head center section plan of the present invention
Fig. 2 is the connection type of scroll print head and main body of the present invention
Wherein, 1- scroll print head, 2- rifle bar, 3- squeeze out shell, the big sleeve of 4-.
Specific embodiment
To facilitate the understanding of the present invention, a more comprehensive description of the invention is given in the following sections with reference to the relevant attached drawings.In attached drawing
Give better embodiment of the invention.But the invention can be realized in many different forms, however it is not limited to herein
Described embodiment.On the contrary, the purpose of providing these embodiments is that making to understand more the disclosure
Add thorough and comprehensive.
It should be noted that it can directly on the other element when element is referred to as " being set to " another element
Or there may also be elements placed in the middle.When an element is considered as " connection " another element, it, which can be, is directly connected to
To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ",
" right side ", " top ", " bottom ", " bottom end ", " top " and similar statement for illustrative purposes only, are not offered as being only
One embodiment.
Unless otherwise defined, all technical and scientific terms used herein and belong to technical field of the invention
The normally understood meaning of technical staff is identical.Term as used herein in the specification of the present invention is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term " and or " used herein includes one or more
Any and all combinations of relevant listed item.To facilitate the understanding of the present invention, below with reference to relevant drawings to this
Invention is described more fully.Better embodiment of the invention is given in attached drawing.But the present invention can be with many not
With form realize, however it is not limited to embodiments described herein.On the contrary, the purpose of providing these embodiments is that making
It makes the present disclosure more fully understandable.
The present invention will be further described with specific embodiment with reference to the accompanying drawing.
A kind of print head applied to FDM printer, refers to attached drawing 1, and the print head of FDM printer includes spirally beating
It prints head (1)；The scroll print head (1) includes squeezing out shell (2) and rifle bar (3)；The rifle bar (3) is inserted in extrusion
In shell (2).
Further, the extrusion shell (2) includes hollow cylindrical part and hollow frusto-conical portion.
Further, the rifle bar (3) is inserted in the column part for squeezing out shell (2), and the periphery of rifle bar (3)
Shell (2) inner wall is closely coupled with squeezing out.
It further, is top-down helicla flute inside the rifle bar (3).
Further, the helicla flute and the angle of horizontal direction are less than 10 degree.
Further, the high-temperature material that the rifle bar is resistance to 400 degree or more.
Further, the spiral groove surface roughness of the rifle bar is 3.2~25.
A kind of print head working principle applied to FDM printer: the helical flow passage to form melted material, spiral
The effect of stick (3) is the self weight resistance increased to melted material, and principle is the gravity straight down melted material, is relied on
Helicoid resolves into two power: X gravity and Y gravity not only change original gravity direction, but also the size of original gravity
Two power are decomposed into, the size of gravity is changed.
Workflow of the invention:
As shown in Fig. 2, when needing FDM printer to print, under the extruding force given by dynamical element, melted material
After excessive sleeve (4), flow into scroll print head (1) of the present invention, the material of melting spiral shell in print head (1) of the invention
Eddy flow is dynamic；When not needing printing, dynamical element stops working at once, acts on the melting in print head of the present invention (1)
The extruding force of material disappears, and because helical structure print head (1) of the invention to the melted material in print head (1) from
There is great resistance again, prevent melted material is from continuing to flow.
