[0024] Please see Figure 1-3 A 3D printing powder unloading device includes two main shell plates 1 and a positioning component, the positioning component being disposed on the side of the main shell plate 1.

[0025] The two main shell plates 1 have a common collection base plate 10 at their bottoms, an arc-shaped plate 2 at the top of each of the two main shell plates 1, a vibration plate 9 on the outer side of each main shell plate 1, and a common jet slider 7 slidably mounted on the outer surface of each of the two main shell plates 1.

[0026] It should be noted that the main shell plate 1 provides a sturdy structural support for the device, while the collection base plate 10 is used to collect the powder unloaded from the printed sample, realizing centralized collection and processing of powder and improving the efficiency and convenience of powder unloading.

[0027] In this embodiment, printed samples can be placed on opposite sides of the two main shell plates 1, support plates 3 are fixedly installed on the outer sides of the two arc-shaped plates 2, and a common fixing rod 4 is fixedly installed on the top of the two support plates 3.

[0028] In this embodiment, the arc plate 2 has a semi-circular structure. The outer surfaces of the main shell plate 1 and the arc plate 2 are provided with a common electrically controlled sliding groove 5. The arc plate 2 not only provides stable support for the printed sample, but also guides the jet slider to slide the powder onto the collection base plate 10 through its semi-circular structure, which further improves the powder unloading efficiency. The support plate 3 and the fixing rod 4 enhance the stability and overall structural strength of the device, ensuring the stability and safety of the device during the powder unloading process.

[0029] In this embodiment, an electronically controlled slider 6 is slidably installed on the inner side of the electronically controlled slide groove 5, and a common jetting slider 7 is fixedly installed on the opposite sides of the two electronically controlled sliders 6. The jetting slider 7 is slidably installed on the inner side of the two main body shell plates 1. A jetting interface 8 is provided on the back side of the jetting slider 7, and a jetting head connected to the jetting interface 8 is provided on the inner side of the jetting interface 8. The cooperation between the electronically controlled slide groove 5 and the electronically controlled slider 6 allows the jetting slider 7 to slide flexibly on the inner side of the main body shell plate 1, thereby achieving precise jetting of different parts of the printed sample. This design not only improves the flexibility of powder unloading, but also avoids the safety hazards that may be caused by manual operation.

[0030] It should be noted that the nozzle inside the spray port 8 can accurately spray air or liquid onto the printed sample, helping the powder to separate from the sample surface more quickly. This design improves the efficiency and effectiveness of powder removal, while avoiding damage to the sample due to excessive force.

[0031] The positioning component includes a positioning slide plate 11, which is disposed on the inner side of the main shell plate 1. The inner side of the positioning slide plate 11 is fixedly installed with the vibrating plate 9. The cooperation between the positioning slide plate 11 and the positioning groove 12 ensures the stable sliding and positioning of the vibrating plate 9 on the inner side of the main shell plate 1. This design not only improves the stability and reliability of the device, but also enables the vibrating plate 9 to more effectively vibrate and remove powder from the printed sample.

[0032] In this embodiment, the inner sides of the two vibrating plates 9 are corresponding, and a row of positioning slide plates 11 is provided at both ends of the two vibrating plates 9. The inner side of the main shell plate 1 is provided with a positioning slide groove 12 that is slidably installed with the positioning slide plate 11. The vibrating plates 9 slide relative to each other and achieve stable vibration with the help of circuit control. Through the vibration, the powder on the printed sample is more easily removed. At the same time, the vibration force is controllable, avoiding damage to the sample due to excessive force. This design not only improves the efficiency and effect of powder removal, but also protects the integrity and quality of the printed sample.

[0033] The beneficial effects of this embodiment are as follows:

[0034] The electric slider 6 drives the jet slider 7, which in turn guides the powder to fall onto the collection base plate 10 through the semi-circular structure of the sliding arc plate 2, thus improving the powder unloading efficiency. The jet head precisely jets air or liquid to assist in the rapid separation of powder while avoiding damage to the sample. In addition, the vibrating plate 9 slides in the positioning groove 12 through the positioning slide plate 11 to stabilize the vibration and unload the powder, further protecting the integrity of the sample.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
