Description

Technical Field

[0001] This utility model relates to the field of printhead technology, and more specifically, to an ultra-high precision sand mold printhead based on piezoelectric inkjet. Background Technology

[0002] When using the ultra-high precision sand mold printhead of piezoelectric inkjet, a piezoelectric switch is needed to turn on the pressurized machine, so that the printhead can achieve pressurized jetting and complete the inkjet operation, thus achieving efficient inkjet printing.

[0003] In the piezoelectric inkjet process, a sand-shaped printhead is needed to spray ink into the print. However, when holding the printhead during inkjet printing, the overall weight is relatively heavy, making it difficult to provide support from the bottom and to rotate the printhead for auxiliary support. This results in poor printing stability and accuracy. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: an ultra-high precision sand mold printhead based on piezoelectric inkjet printing, comprising an ink cartridge, one end of which is fixedly connected to a printhead for inkjet printing, and a support displacement assembly installed at the bottom of the outer wall of the ink cartridge, the support displacement assembly comprising: A linkage column is fixedly located at the bottom of the outer wall of the ink cartridge. A handle is rotatably mounted on the outer wall of the linkage column. Limiting rings are rotatably mounted at the top and bottom of the handle. Both limiting rings are fixedly connected to the linkage column. A support sleeve is fixedly connected to the lower surface of the handle and near its edge, and a disc is fixedly connected to the outer wall of the support sleeve; Multiple branch bars are distributed and fixedly connected to the outer wall of the disk.

[0005] In a preferred embodiment, the outer wall of the linkage column and the inner wall of the grip are both smooth surfaces, and the two limiting rings are symmetrically arranged about the grip.

[0006] In a preferred embodiment, the center point of the linkage column and the center point of the support sleeve are on the same vertical line, and the cross-sectional shape of the linkage column is circular.

[0007] In a preferred embodiment, the cross-sectional shape of the disc is annular, and the plurality of branch strips are arranged in a circumferentially equidistant distribution, wherein the cross-sectional shape of the branch strips is rectangular.

[0008] In a preferred embodiment, a cover is threaded to the top of the outer wall of the ink cartridge, and the top cross-sectional shape of the cover is polygonal.

[0009] In a preferred embodiment, a displacement post is provided on one side of the cover, and the displacement post is fixedly connected to the ink cartridge. A limiting block is fixedly connected to the top of the displacement column, and a piezoelectric switch is fixedly installed on one side of the outer wall of the limiting block. A booster fan is fixedly installed at the other end of the ink cylinder, and a connecting pipe is fixedly connected to the input end of the booster fan.

[0010] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a support displacement component, where the handle drives the support sleeve to move downwards, the disc body fits against the table, multiple branch strips are distributed on the table, the ink cartridge drives the linkage column to rotate, the linkage column drives two limit rings to rotate, the two limit rings rotate stably on the handle, and the printhead achieves stable rotation and ink ejection.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 - Figure 4 The diagram shows an ultra-high precision sand mold printhead based on piezoelectric inkjet. This ultra-high precision sand mold printhead based on piezoelectric inkjet is equipped with a support displacement component. The support displacement component enables the two limiting rings 5 ​​to rotate stably on the handle 4, and achieves stable rotation and ink ejection through the printhead 2. The ink cartridge 1 rotates and ejects ink stably on the horizontal plane, which greatly improves the accuracy of inkjet printing and completes the inkjet printing of sand mold materials. The specific structural settings of the support displacement component are as follows.

[0019] In this embodiment, as Figure 1 - Figure 3 As shown, one end of the ink cartridge 1 is fixedly connected to a printhead 2 for inkjet printing. A support displacement assembly is installed at the bottom of the outer wall of the ink cartridge 1. The support displacement assembly includes: a linkage column 3, fixedly located at the bottom of the outer wall of the ink cartridge 1, with a handle 4 rotatably mounted on the outer wall of the linkage column 3. Limiting rings 5 ​​are rotatably mounted at both the top and bottom of the handle 4, and both limiting rings 5 ​​are fixedly connected to the linkage column 3; a support sleeve 6, fixedly connected to the lower surface of the handle 4 near its edge, with a disk body 7 fixedly connected to the outer wall of the support sleeve 6; and multiple branch bars 8, all distributed and fixedly connected to the outer wall of the disk body 7. The outer wall of the linkage column 3 and the inner wall of the handle 4 are both smooth surfaces, and the two limiting rings 5 ​​are symmetrically arranged about the handle 4. The center point of the linkage column 3 and the center point of the support sleeve 6 are on the same vertical line, and the cross-sectional shape of the linkage column 3 is circular. The cross-sectional shape of the disk body 7 is annular, and the multiple branch bars 8 are arranged equidistantly around the circumference, with the cross-sectional shape of the branch bars 8 being rectangular.

[0020] In this embodiment, as Figure 1 As shown, a cover 9 is threadedly connected to the top of the outer wall of the ink cartridge 1. The top cross-sectional shape of the cover 9 is polygonal, so as to facilitate the reversal of the cover 9. The cover 9 is threadedly separated from the ink cartridge 1, and the printing ink is injected into the ink cartridge 1 for storage, thus realizing the injection operation.

[0021] This technology, based on an ultra-high precision sand mold printhead using piezoelectric inkjet, involves reversing the cover 9 to separate it from the ink cartridge 1, allowing ink to be injected into the cartridge 1 for storage. Simultaneously, the cover 9 is reversed, and the hand grips the handle 4, causing the support sleeve 6 to move downwards. The support sleeve 6 then moves the disc 7 downwards, placing it against the table. The disc 7 supports multiple branch strips 8, which are distributed on the table. Rotating the ink cartridge 1 causes the linkage column 3 to rotate, which in turn rotates two limiting rings 5. These two limiting rings 5 ​​rotate stably on the handle 4. By pressurizing the inside of the ink cartridge 1, the ink is delivered to the printhead 2, where it is ejected onto the printing material. This allows the ink cartridge 1 to rotate stably on a horizontal surface during inkjet printing.

[0022] In this embodiment, as Figure 1 - Figure 4 As shown, a displacement post 10 is provided on one side of the cover 9, and the displacement post 10 is fixedly connected to the ink cylinder 1; a limit block 11 is fixedly connected to the top of the displacement post 10, and a piezoelectric switch 12 is fixedly installed on one side of the outer wall of the limit block 11; a booster fan 13 is fixedly installed at the other end of the ink cylinder 1, and a connecting pipe 14 is fixedly connected to the input end of the booster fan 13.

[0023] This technology is based on an ultra-high precision sand mold printhead using piezoelectric inkjet printing. When in use, the hand is held on the outer wall of the displacement post 10 and the outer wall of the limiting block 11. The outer wall of the limiting block 11 increases the friction of the hand. Then, the booster fan 13 is turned on by the piezoelectric switch 12. The circuit between the piezoelectric switch 12 and the booster fan 13 is connected in series, so the piezoelectric switch 12 can be energized in series to turn on the booster fan 13. The booster fan 13 draws external air into the connecting pipe 14, which then pours it into the ink cartridge 1, thus spraying the ink inside the ink cartridge 1.

[0024] The piezoelectric switch 12 and the booster fan 13, which are not described in detail in the instruction manual, are connected in series. Series control circuits are common knowledge circuits, so they are not described in detail and are all existing technologies known to those skilled in the art. The model parameters of each electrical appliance are not specifically limited and conventional equipment can be used. Electrical control components not mentioned in this technical solution are not shown in the figure because they are existing technologies, and will not be described here.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
