Therefore, developing an extruder specifically tailored to the needs of sugar painting 3D printing is crucial for advancing the automation of sugar painting production and enabling personalized customization.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides an extrusion device for a sugar painting 3D printer, such as Figure 1-Figure 3 As shown, it includes a storage barrel 1, one end of the storage barrel 1 is equipped with a discharge end 12, the other end of the storage barrel 1 is equipped with a shell 2, a bracket 3 is installed in the shell 2, a feeding drive motor 15 is installed on the bracket 3, and the output shaft of the feeding drive motor 15 is equipped with a rotating shaft 13, and the outer wall of the bottom end of the rotating shaft 13 is equipped with a spiral feeding piece 14, and the blade spacing of the spiral feeding piece 14 is changed to a gradual distance. The gradual distance can enhance the extrusion force and prevent the raw material from clogging the nozzle. An adjusting motor 32 is also installed on the bracket 3. The output shaft of the adjusting motor 32 drives the storage barrel 1 to move up and down through the screw assembly, driving the end of the rotating shaft 13 to extend out or extend into the discharge end 12. A discharge port is provided at one end of the discharge end 12 to facilitate material extrusion. The discharge end 12 is installed at one end of the storage barrel 1, which is used to accurately control the extrusion of sugar material, thereby ensuring the accuracy and fineness of sugar painting printing. Secondly, the bracket 3 mounted within the housing 2 firmly supports the feed drive motor 15 and the adjustment motor 32, ensuring the structural stability and operational reliability of the entire extruder. The output shaft of the feed drive motor 15 is mounted with a rotating shaft 13, and the outer wall of the bottom end of the rotating shaft 13 is mounted with a spiral feed piece 14. This design ensures efficient and uniform feeding of the sugar material, avoiding problems such as material blockage and uneven extrusion, thereby improving the printing quality and efficiency of sugar paintings.

[0023] It's particularly noteworthy that the output shaft of the adjustment motor 32 drives the accumulator 1 up and down via a screw assembly, thereby driving the end of the rotating shaft 13 to extend into or out of the discharge end 12. This innovative design allows the extruder to flexibly adjust the amount and position of the sugar material extruded according to the specific needs of sugar painting printing, further enhancing the automation and customization capabilities of sugar painting production.

[0024] In this embodiment, a feeding port 11 is provided on one side of the top of the storage barrel 1 , and a cover plate is detachably mounted on the feeding port 11 to facilitate the addition of materials and the sealing effect.

[0025] Specifically, a heat dissipation hole 21 is provided on the surface of the housing 2, and a heat dissipation fan 22 is installed inside the housing 2 to improve the heat dissipation effect of the device.

[0026] Furthermore, a lifting adjustment plate 31 is installed at the bottom of the storage barrel 1, and the screw assembly includes an adjusting screw 33. The output shaft of the adjusting motor 32 is connected to the adjusting screw 33. A screw slider 34 is installed on the adjusting screw 33. The screw slider 34 is connected to the lifting adjustment plate 31 through a fixed plate. The adjusting motor 32 drives the adjusting screw 33 to rotate, thereby realizing the lifting and lowering of the lifting adjustment plate 31, driving the storage barrel 1 to move up and down, so that the end of the rotating shaft 13 extends out or extends into the discharge end 12.

[0027] Furthermore, a slide rail 311 is installed on the top of one end of the lifting adjustment plate 31, and a track groove is provided near the slide rail 311 of the bracket 3. The slide rail 311 slides with the track groove of the bracket 3 to ensure stable lifting of the lifting adjustment plate 31.

[0028] Furthermore, the feeding drive motor 15 and the regulating motor 32 are both fixed to the bracket 3 by bolts, and a partition is provided between the feeding drive motor 15 and the regulating motor 32 to ensure that the two motors work independently without interfering with each other.

[0029] Furthermore, the discharge end 12 is a cylindrical structure, and one end of the rotating shaft 13 close to the spiral feeding piece 14 extends into the inner side of the discharge end 12 to facilitate the discharge of materials in the discharge end 12.

[0030] When using the extruder device of the sugar painting 3D printer of the present invention, sugar material is first added to the storage barrel 1 through the feed port 11, and then the cover plate is closed to ensure a tight seal. An adjustment motor 32 drives the storage barrel 1 up and down via a screw assembly, depending on the specific printing requirements. Specifically, the output shaft of the adjustment motor 32 is connected to the adjustment screw 33, and the screw slider 34 on the adjustment screw 33 is connected to the lifting adjustment plate 31 via a fixed plate. When the adjustment motor 32 rotates, the adjustment screw 33 also rotates, driving the screw slider 34 and the lifting adjustment plate 31 up and down, thereby achieving the up and down movement of the storage barrel 1. This design allows the end of the rotating shaft 13 to extend into or out of the discharge port 12, allowing for flexible adjustment of the sugar material extrusion rate and position. Once the material enters the discharge port 12, the feed drive motor 15 is activated, and its output shaft rotates the rotating shaft 13. The spiral feed piece 14 at the bottom of the rotating shaft 13 rotates accordingly, evenly and efficiently extruding the sugar material in the storage barrel 1 from the discharge port 12.

[0031] At the same time, the heat dissipation holes 21 on the surface of the housing 2 and the internal heat dissipation fan 22 work together to effectively reduce the operating temperature of the equipment and ensure that the extrusion device can operate stably for a long time.

[0032] Finally, the precisely controlled sugar material is extruded through the discharge port of the discharge end 12 to form a delicate and precise sugar painting. The entire extrusion process is efficient and stable, and can be flexibly adjusted according to demand, realizing the automation and personalized customization of sugar painting production.

[0033] Finally, it should be noted that the electronic components of the feeding drive motor 15, the adjustment motor 32, etc. in this embodiment are all universal standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods.
