Abstract
A kind of FDM 3D printing equipment anti-blocking sprayer device of the present invention, nozzle body are connected in FDM 3D printing equipment, and coolant liquid is arranged by import to outlet through supercooling, are reached in water tank, then are pumped into cooling liquid inlet by water pump and are completed circulation.The present apparatus is designed by reasonable structure, can be allowed and be met and discussed temperature stabilization in certain section, wire rod will not be allowed, which to melt in advance, causes spray head to block, and greatly reduces the replacement frequency of spray head internal insulation material, improves the stability of FDM 3D printer.
Description
Technical field
The present invention relates to 3D printing technique field, in particular to a kind of FDM 3D printing equipment anti-blocking sprayer device.
Background technique
3D printing fused glass pellet technology (FDM) be called fuse deposition, it be by Filamentous heat-fusible materials heating and melting,
It is squeezed and is gushed out by the spray head with a minute nozzle.Hot melt material melt after from nozzle spray, be deposited on production panel or
On the cured material of person's preceding layer, temperature starts to solidify after being lower than solidification temperature, is formed finally by the layer upon layer of material
The working principle of finished product.
Common 3D printer is using fusion sediment rapid shaping.Fusion sediment existing FDM 3D printing on the market
The case where equipment often occurs wire vent in actual use and has some setbacks, and spray head blocks.
Summary of the invention
The object of the present invention is to provide a kind of FDM 3D printing equipment anti-blocking sprayer devices.
In order to solve the above technical problems, the present invention realizes as follows:
A kind of FDM 3D printing equipment anti-blocking sprayer device, including hot melt nozzle body (1), inner flow passage (2), transition every
Thermal (3), the cold row (4) of heat dissipation, water tank and temperature sensor (5), water pump (6)；
The inside of inner flow passage (2) is equipped with transition heat-proof device (3), and inner flow passage (2) and hot melt nozzle body (1) are even
It connects, one end of inner flow passage (2) is connect by cooling liquid outlet with the one end for cold row (4) of radiating, the other end for cold row (4) of radiating
It is connect with water tank and temperature sensor (5), water tank and temperature sensor (5) are connect with water pump (6), and water pump (6) passes through coolant liquid
Import is connect with the other end of inner flow passage (2).
The positive effect of the present invention is: the present apparatus improves the stability of FDM 3D printing equipment, and product one-pass molding is kept away
Having exempted from printing, equipment greatly improves product quality because spray head blocks the tomography occurred on the way.
Furthermore it decreases since spray head front-end temperature is excessively high, it is necessary to which the often frequency of replacement transition thermal insulator subtracts significantly
The consumption of vulnerable part is lacked.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the prior art；
Fig. 2 is FDM 3D printing equipment anti-blocking sprayer apparatus structure schematic diagram.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in Fig. 2, a kind of FDM 3D printing equipment anti-blocking sprayer device of the present invention, including hot melt nozzle body
1, inner flow passage 2, transition heat-proof device 3, the cold row 4 of heat dissipation, water tank and temperature sensor 5, water pump 6.
The inside of inner flow passage 2 is equipped with transition heat-proof device 3, and inner flow passage 2 is connect with hot melt nozzle body 1, inside stream
The one end in road 2 is connect by cooling liquid outlet with the one end for cold row 4 of radiating, and the other end and water tank and temperature for cold row 4 of radiating pass
Sensor 5 connects, and water tank and temperature sensor 5 are connect with water pump 6, and water pump 6 passes through the other end of cooling liquid inlet and inner flow passage 2
Connection.
It is anti-blocking meet and discuss be mounted in FDM 3D printing equipment after, water pump be powered, coolant liquid by water pump smoke by import to
Outlet takes away hot melt and meets and discusses feed end heat, arranges through supercooling, transfers heat to air, and coolant temperature is restored to can be used
And it reaches in water tank, then cooling liquid inlet is pumped by water pump and completes circulation.
The present invention is not limited to above-mentioned preferred forms, anyone can show that other are various under the inspiration of the present invention
The product of form, however, make any variation in its shape or structure, it is all that there is the identical or similar skill with the present invention
Art scheme, is within the scope of the present invention.
