Description
Technical field
The utility model relates to petroleum equipment technical field, in particular to a kind of dynamic liquid level of photocuring 3D printing equipment
Control device.
Background technique
Photocuring 3D printing technique (SLA) is that occur and realize a kind of rapid prototyping technology of commercialization earliest in the world,
It is also one of most deep, most widely used rapid prototyping technology of research.It mainly uses photosensitive resin as raw material, benefit
It can quick-setting characteristic under UV laser beam irradiation with liquid photosensitive resin.Photosensitive resin is generally liquid, it is certain
Cause polymerization reaction at once under ultraviolet light (250nm~400nm) irradiation of wavelength, completes solidification.SLA is by specific wavelength and by force
The ultraviolet light of degree focuses on photo-curing material surface, is allowed to by point to line, by the consecutive solidification of line to face, to complete a layer
The molding in section.
Photocuring 3D printing technique is-item energy conservation and clean and environment-friendly technology, it is energy saving --- and energy consumption is only tradition
/ 10th of mercury lamp, and be free of solvent, have protective effect to ecological environment, poison gas and carbon dioxide will not be discharged to atmosphere,
Therefore it is known as " green technology ".
Due to the particularity of ultraviolet curing process, the moulding cylinder size of equipment determines its disposable Quick formed part appearance
The size of size.What therefore the moulding cylinder size of uv equipment often designed is very big, then needs to be completely filled with liquid light in cylinder
Quick resin.But print demand it is not high when, resin can occur slowly rotten with environment temperature and humidity in cylinder, eventually lead to
Photosensitive resin failure, causes lot of materials to waste.
The moulding cylinder size of the photocuring 3D printing equipment of market is larger at present, and when printing needs a large amount of liquid resin complete
Moulding cylinder is filled up entirely, and the amount of resin actually used in printing is lower, stock utilization is low.
Utility model content
The purpose of the utility model is to provide a kind of dynamic liquid level control devices of photocuring 3D printing equipment.
In order to solve the above technical problems, the utility model is realized as follows:
A kind of dynamic liquid level control device of photocuring 3D printing equipment, including scraper assembly (1), metal cap (2), molding
Cylinder (3), heating module (4), closed air bag (5), tracheae (6), air pump (7), angle bar frame (8), welding bottom plate (9), liquid level pass
Sensor (10), assembly positioning plate (11)；
The assembly positioning plate (11) is equipped with the metal cap (2)；Internal in the metal cap (2), the scraper is total
It is arranged on the assembly positioning plate (11) at (1), is equipped with the liquid level sensor (10) on the outside of the scraper assembly (1)；
It is fixedly connected at the top of the bottom and the moulding cylinder (3) of assembly positioning plate (11)；Moulding cylinder (3) week
Enclosing close fit has the heating module (4)；The bottom of the moulding cylinder (3) is connect with the top of the angle bar frame (8), institute
The bottom for stating angle bar frame (8) is connect with the welding bottom plate (9)；
The closed air bag (5) is bolted on the moulding cylinder (3) bottom, and closed air bag (5) bottom surface connects
The tracheae (6) are connected to, the air pump (7) passed through in the moulding cylinder (3) bottom and the angle bar frame (8) connects, composition one
Cover closed gas exchange systems.
The good effect of the utility model is: the present apparatus can adjust moulding cylinder material infilling space effectively to make material
Utilization rate greatly improves, and greatly reduces in cylinder resin as environment temperature and humidity can occur slowly rotten and lead to photosensitive resin
The generation of failure conditions reduces resin raw material waste.
Detailed description of the invention
The structural schematic diagram of Fig. 1 the utility model.
Wherein: 1 is scraper assembly；2 be metal cap；3 be moulding cylinder；4 be heating module；5 be air bag；6 be tracheae；7 are
Air pump；8 be angle bar frame；9 be welding bottom plate；10 be liquid level sensor；11 be assembly positioning plate.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, a kind of dynamic liquid level of photocuring 3D printing equipment of the utility model one embodiment controls dress
It sets, including scraper assembly 1, metal cap 2, moulding cylinder 3, heating module 4, closed air bag 5, tracheae 6, air pump 7, angle bar frame 8, weldering
Connect bottom plate 9, liquid level sensor 10, assembly positioning plate 11.
It assembles positioning plate 11 and is equipped with metal cap 2；Inside metal cap 2, the setting of scraper assembly 1 is in assembly positioning plate 11
On, liquid level sensor 10 is equipped on the outside of scraper assembly 1.
The bottom of assembly positioning plate 11 is fixedly connected with the top of moulding cylinder 3；3 surrounding close fit of moulding cylinder has heated mould
Block 4；The bottom of moulding cylinder 3 is connect with the top of angle bar frame 8, and the bottom of angle bar frame 8 is connect with welding bottom plate 9.
Closed air bag 5 is bolted on 3 bottom of moulding cylinder, and closed 5 bottom surface of air bag is connected with tracheae 6, passes through molding
Air pump 7 in 3 bottom of cylinder and angle bar frame 8 connects, and forms a set of closed gas exchange systems.
After the starting of photocuring 3D printer, heating module 4 starts, and scraper assembly 1 is in the photosensitive tree of special liquid in moulding cylinder 3
Rouge surface walks back and forth, a certain proportion of ultraviolet initiator of liquid photosensitive resin mixing, can be in the ultraviolet light of certain wavelength
Polymerization reaction solidification immediately occurred under irradiation；Ultraviolet laser is respectively layered cross section profile along part, carries out to liquid resin point-by-point
Scanning；The thin resin layer being scanned can generate polymerization reaction, gradually form line by point, ultimately form a thin layer of part
Solidify section, and the resin not being scanned keeps original liquid；When one layer of solidification finishes, self-powered platform moves a layer
The distance of piece thickness covers one layer of new liquid resin in upper one layer of resin surface having been cured, to carry out again again
Scanning solidification；Air pump 7 is controlled by the returned data that liquid level sensor 10 detects；When liquid photosensitive resin liquid level is reduced to zero-bit
When, air pump 7 starts automatically, develops gas processed, and transtracheal 6 is inflated into air bag 5, and air bag expansion makes air bag gradually be lifted liquid with tolerance
State photosensitive resin liquid level, liquid level lifting is until reach zero-bit, to effectively increase liquid photosensitive resin in the height of moulding cylinder 3
Degree, it is ensured that circulation solidification, new cured one layer is firmly bonded in preceding layer, loops back and forth like this, until entire part is former
Type manufacture finishes.When liquid level monitoring value is more than zero-bit, the starting pumping of air pump 7, balloon contraction, liquid level reduction；Whole process is whole
It is completed in closed exchange system.
