The extrusion head used to extrude the slurry will be provided with a stirring element to prevent the slurry from solidifying;

However, the number and position of the stirring parts are generally fixed, and the staff cannot adjust it according to the viscosity of the slurry.

In view of the above shortcomings, the creator of this new model believes that it is necessary to make corrections, so with years of experience in related technologies and product design and manufacturing, adhering to good design concepts, research and creation for the above shortcomings, after continuous efforts, finally. This new type of slurry 3D printing mixing and extruding device is launched, in order to correct the product structure and improve the product's excellent efficacy.

The main purpose of this new type of slurry 3D printing stirring and extruding device is to provide a slurry extrusion head structure that can adjust the number and position of stirring pieces.

In order to achieve the purpose of the previous disclosure, the new type of slurry 3D printing stirring and extruding device includes:

A main unit has a base, a connecting portion and a cover below the connecting portion are fixed on the outside of the base, a driver is fixed on the top of the base, and the driver has a drive shaft, the drive shaft passes downward. A rotating shaft is fixedly connected to the base, the outside of the rotating shaft is concavely provided with a plurality of assembly holes, and the outside of the rotating shaft is formed with a push screw thread below each assembly hole;

at least one stirring piece, the stirring piece has an assembling rod, a blade is formed on the outside of the assembling rod, and the assembling rods of each stirring piece are respectively assembled in each of the assembling holes;

A material holding pipe has a pipe body, the outside of the pipe body is provided with a feeding port connecting the inside and the outside of the pipe body, the pipe body is detachable and tightly fixed under the cover, so that the rotating shaft, the The pushing screw and each of the stirring elements are located in the pipe body.

In this way, in this creation, a plurality of assembly holes are provided on the rotating shaft, and the stirring element is assembled after the assembly hole. When using this creation for stirring and extruding, the staff can freely adjust the stirring element according to the situation of stirring and extruding. The number, angle and position of the assembly, so that the pipe body can have the best stirring fluidity, so as to avoid the uneven homogenization of the slurry, which can improve the shortcomings of the previous stirring parts that cannot be adjusted freely. It is obvious that this work is a very progressive The product.

[Please refer to the first to the third picture] The new creation relates to a slurry 3D printing stirring and extruding device, which includes:

A main unit (1) has a base (11), a connecting portion (12) and a cover (13) below the connecting portion (12) are fixed on the outside of the base (11), the base (11) ) top is fixed with a driver (14), the driver (14) has a drive shaft (141), the drive shaft (141) goes down through the base (11) and is exposed at the bottom end of the base (11), The drive shaft (141) is fixedly connected to a rotating shaft (15), and a plurality of assembly holes (16) are concavely formed on the outside of the rotating shaft (15). Push screw (17);

A plurality of stirring pieces (2), the stirring pieces (2) have an assembly rod (21), a blade (22) is formed on the outside of the assembly rod (21), and the assembly rods (21) of the stirring pieces (2) are respectively assembled in each of the assembly holes (16);

a material-containing pipe (3), which has a pipe body (31), and the outside of the pipe body (31) is provided with a material inlet (32) connecting the inside and the outside of the pipe body (31), the pipe body (31) It is detachably and tightly fixed under the cover (13), so that the rotating shaft (15), the pushing screw teeth (17) and the stirring pieces (2) are all located in the pipe body (31).

[Please refer to the first to the third picture] The tube body (31) is set in two stages and tapers downward, and the outer diameter of the upper half of the push screw thread (17) is matched with the tube body (31) The shape is tapered from top to bottom, and the connecting part (12) is used to connect to the three-dimensional driving frame (10) of a 3D printer, so that the creation can be driven to move three-dimensionally, and the feeding port (32) It is used to connect a slurry conveying equipment (not shown in the figure) through a pipe;

Therefore, when printing, the three-dimensional driving frame (10) will drive the three-dimensional displacement of the work, and the slurry conveying device will send the slurry from the feeding port (32) into the tube body (31), while the driver (14) Then the rotating shaft (15) is driven to rotate, so that the stirring element (2) stirs the slurry in the pipe, and then the slurry material is extruded from the end of the pipe body (31) by the push screw (17), and then gradually formed into a predetermined shape of slurry body material finished product;

The feature of this creation is that the staff can increase or decrease the number of the stirring pieces (2) assembled on the rotating shaft (15) according to the stirring and extruding conditions of the slurry, and can adjust the position of the stirring pieces (2) so that the The slurry in the material holding pipe (3) is kept at the best stirring fluidity to avoid uneven stirring, and the gap between the assembly rod (21) and the assembly hole (16) of the stirring member (2) can be adjusted. Thread and other suitable combination methods to achieve the effect of quick disassembly and assembly.

[Please refer to Figures 1 to 3] In the present embodiment, the assembly holes (16) are all orthogonal to the axis of the rotating shaft (15), while in other embodiments, the assembly holes (16) It can be set to have different angles with the axis of the rotating shaft (15), so that the stirring piece (2) is inclined after being assembled, so the staff can assemble the stirring piece (2) in the holes of different angles according to the needs, which can make the stirring piece (2) more stable. Satisfy the needs of homogeneous materials.

Only the above is only a preferred embodiment of the novel creation, and should not be used to limit the scope of the novel creation. That is to say, all equivalent changes and modifications made in accordance with the scope of the patent application should still fall within the scope of the invention patent.

In summary, when it is known that the new creation is novel and progressive, and the new creation has not been seen in any publications, it shall comply with the provisions of Article 104 of the Patent Law and Article 120 of the Patent Law and Article 22 of the Patent Law.
