Description
Technical Field
[0001] The utility model relates to the technical field of 3D printing, in particular to a heat insulation and dust removal device for a printing module and a 3D printer. Background Art
[0002] The wax-type 3D printer belongs to a kind of additive manufacturing equipment. By spraying the wax material in a liquid state after high-temperature heating onto the printing platform, the wax material then solidifies into a solid state at normal temperature, and a model is built by stacking layer by layer. Due to the advantages of high precision and smooth surface of the wax-sprayed 3D printing model, the wax-sprayed 3D printer is widely used in manufacturing industries such as jewelry, aerospace, and engines.
[0003] At present, during the printing process of the wax-type 3D printer, the printing module of the spray vehicle needs to be heated at a high temperature (the maximum temperature can reach 120 °C). When the wax liquid is ejected from the printing module, a large amount of dust will be generated, and there are high-temperature and high-dust phenomena around the spray vehicle. This will not only have a greater impact on the forming quality of the model in the printing area, but also pose a relatively dangerous safety hazard to the operator. Therefore, a heat insulation and dust removal device is needed to achieve the effects of heat insulation, heat dissipation, and dust removal for the printing module. Summary of the Utility Model
[0004] To solve the above technical problems, the utility model provides a heat insulation and dust removal device for a printing module with dust removal, heat insulation, and heat dissipation functions and a 3D printer thereof.

The printing module is fixed to the suspension bracket. The first heat insulation and dust removal cover is arranged on the side of the suspension bracket away from the printing module. The first heat insulation and dust removal cover is provided with a first dust removal and heat dissipation port. The second heat insulation and dust removal cover is arranged around the side wall of the printing module. An air suction groove is arranged in the second heat insulation and dust removal cover. The air suction groove covers one or more side walls of the printing module. The air suction groove is communicated with a second dust removal and heat dissipation port.
[0007] Further, the first dust removal and heat dissipation port and the second dust removal and heat dissipation port are communicated with a dust removal fan; the air suction groove covers three or four side walls of the printing module.

By making the opening area of the air suction groove as large as possible, the air suction and heat dissipation effect is enhanced. When the hot air is sucked in from the notch of the air suction groove, it is discharged through the second dust removal and heat dissipation port.

A third heat insulation cotton is arranged on the outer wall of the second flow channel block, and a fourth heat insulation cotton is arranged on the outer wall of the first flow channel block.
[0011] Further, the first flow channel block is connected to an ink inlet pipe; a third heat insulation and dust removal cover is arranged to cover the first flow channel block; the shape of the third heat insulation and dust removal cover matches that of the first flow channel block; the third heat insulation and dust removal cover is provided with a second opening, and the second opening corresponds to the position of the ink inlet pipe.
[0012] Further, a heat insulation plate is arranged on one side of the printing module away from the hanging bracket, and the heat insulation plate is provided with a first opening corresponding to the nozzle opening of the printing module. The heat insulation plate can effectively insulate heat and does not affect normal printing.
[0013] Further, a heat insulation pad is arranged between the hanging bracket and the printing module. The heat insulation pad is provided to prevent a large amount of heat from being conducted to the hanging bracket.
[0014] A 3D printer includes the printing module heat insulation and dust removal device as described above.

[0028] See Figures 1-4 , which is an embodiment of a heat insulation and dust removal device 1 for a printing module of the present application. The heat insulation and dust removal device 1 for a printing module includes a printing module 2, a suspension bracket 3, a first heat insulation and dust removal cover 4, and a second heat insulation and dust removal cover 5.

The printing module 2 is provided with a heating component for heating the printing module, so that phase change ink such as wax material can be ejected in a liquid state from the nozzle opening 21 of the printing module.
[0029] The first heat insulation and dust removal cover 4 is disposed on the side of the suspension bracket 3 away from the printing module 2, that is, on the top of the suspension bracket 3. The first heat insulation and dust removal cover 4 is provided with a first dust removal and heat dissipation opening 41, and the first dust removal and heat dissipation opening 41 is connected to a dust removal fan (not shown in the drawings) through a pipeline to suck away the excess heat and dust of the printing module 2, thereby playing a role in heat insulation, heat dissipation, and dust removal. An insulation pad 61 is provided between the suspension bracket 3 and the printing module 2 to prevent a large amount of heat from being conducted to the suspension bracket 3.
[0030] The second heat insulation and dust removal cover 5 is disposed around the side wall of the printing module 2. An air suction groove 51 is provided in the second heat insulation and dust removal cover 5. The air suction groove 51 covers one or more side walls of the printing module 2, and the air suction groove 51 communicates with a second dust removal and heat dissipation opening 52. The second dust removal and heat dissipation opening 52 is connected to a dust removal fan (not shown in the drawings) through a pipeline. See, for example, Figure 3 、 Figure 4 the red part. In this embodiment, due to structural limitations, the air suction groove 51 covers three side walls of the printing module and has a C-shaped structure. It can be understood that the air suction groove 51 can also cover four side walls of the printing module to play a better role in air suction and heat dissipation.
[0031] Preferably, the notch of the air suction groove 51 is disposed downward away from the suspension bracket 3, the bottom of the air suction groove 51 is close to the top of the second heat insulation and dust removal cover 5, and the depth of the air suction groove 51 is close to the height of the second heat insulation and dust removal cover 5, so that the opening area of the air suction groove 51 is as large as possible to enhance the air suction and heat dissipation effect.

Pipelines are respectively arranged inside the first flow channel block 23 and the second flow channel block 24 for pipeline transfer with the nozzle head main body 22 and other components. The first flow channel block 23 is connected to the ink inlet pipe 7. The first flow channel block 23 and the second flow channel block 24 are arranged above the nozzle head main body 22.
[0035] In order to achieve a better heat insulation and heat preservation effect, first heat insulation cotton 81 and second heat insulation cotton 82 are respectively arranged on the two side walls of the printing module 2 with relatively large areas. The first heat insulation cotton 81 and the second heat insulation cotton 82 are arranged between the side walls of the printing module 2 and the second heat insulation and dust removal cover 5. The second flow channel block 24 is provided with third heat insulation cotton 83, and the third heat insulation cotton 83 covers two adjacent side walls of the second flow channel block 24. The third heat insulation cotton 83 is arranged close to the first flow channel block 23 to prevent heat transfer between the first flow channel block 23 and the second flow channel block 24.
