[0008] As a further improvement of the above technical solution: the negative pressure compaction unit generates negative pressure during the loading process, so that the powdery materials form clusters and reduce dust emission.
[0009] As a further improvement of the above technical solution: the buffer silo is provided with a plurality of independent chambers, each chamber corresponds to a charging head, and the total capacity meets the charging requirements of a single row of crucibles.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0032] A powder automatic crucible charging system comprises: a kiln car 1, which is provided with multiple rows of empty crucibles, each row comprising multiple crucibles arranged in parallel; a crucible pushing mechanism 2, which is used to push the kiln car 1 to the charging station in sections and position it; a multi-head loader 3, which comprises: a top silo 31, which is connected to a material source through a negative pressure suction pipe and is provided with a rotary valve 32 to control the feed flow rate; a buffer silo 33, which stores the amount of material required for charging a single row of crucibles; an adjustable charging head assembly 34, which comprises charging heads corresponding to the number of crucibles, and the charging head is vertically moved by a lifting mechanism 35; a negative pressure compacting unit 36, which is arranged at the end of the charging head for compacting the material; a spiral feeding mechanism 37, which controls the material conveying rate; a position adjustment mechanism 4, which is used to correct the concentricity of the charging head and the crucible; a control system 5, which coordinates the action sequence of the pushing mechanism, the loader and the adjustment mechanism.
[0033] The position adjustment mechanism 4 includes a lateral adjustment mechanism, a longitudinal adjustment mechanism and an angle adjustment mechanism, and can be driven manually or automatically.
[0034] The lifting mechanism 35 comprises a servo drive assembly, a lead screw transmission assembly and a guide limit assembly, so that the charging head stops after descending to a preset position in the crucible.
[0035] The negative pressure compacting unit 36 generates negative pressure during the loading process, so that the powdery materials are clustered and dust emission is reduced.
[0036] The buffer bin 33 is provided with a plurality of independent chambers, each chamber corresponds to a charging head, and the total capacity meets the charging requirements of a single row of crucibles.
[0037] The speed of the screw feeding mechanism 37 is adjustable to suit the conveying characteristics of different materials.
[0038] After completing the loading of a single row of crucibles, the control system 5 triggers the crucible pushing mechanism 2 to move the next row of empty crucibles to the loading station.
[0039] The top silo 31 starts to refill when the material amount in the buffer silo 33 is lower than a threshold value, and the timing of refilling is synchronized with the pushing action of the kiln car 1 .

The charging effect is faster and more environmentally friendly than direct charging of powder, with almost no dust emission.
[0046] S7, at this time, the vertical feeding mechanism composed of a motor, a reducer, and a screw rod intervenes and starts feeding. The feeding speed can be adjusted by the frequency of the motor. Different speeds can be set according to the different characteristics of the material.
[0047] S8. The above charging machine starts to charge the crucible. After a certain period of time, the charging head automatically rises to a safe position and stops the negative pressure.
[0048] S9, the crucible pushing mechanism 2 intervenes again, pushes the next row of empty crucibles to the bottom of the charging head, and repeats 4-8 again, repeatedly loading until all the empty crucibles on the kiln car 1 are filled;
[0049] S10. Since the kiln car 1 generally has 6 rows of crucibles, when the third row of crucibles is loaded, the top silo 31 of the single machine starts to refill the buffer silo 33, thereby achieving the purpose of continuous production.
[0050] By adopting the segmented pushing by the kiln car 1, synchronous loading of multiple rows of crucibles (such as 5-head loading machines working at the same time) and the dynamic feeding mechanism of the buffer silo 33, the loading stations are seamlessly connected to avoid downtime and waiting; when filling the third row of crucibles, the top silo 31 is triggered to replenish materials to ensure that the material supply matches the charging rhythm and supports continuous production; the negative pressure compaction unit 36 at the end of the charging head squeezes the material through negative pressure and absorbs cavitations, so that the powder forms dense clusters and reduces dust emission during the loading process; the spiral feeding mechanism 37 is combined with variable frequency speed regulation technology to adapt to different material characteristics and avoid material stratification or blockage; the position adjustment mechanism The structure 4 (lateral / vertical / angle adjustment) cooperates with the manual or automatic detection system to realize the rapid alignment of the charging head and the crucible; the servo-driven lifting mechanism 35 accurately controls the descent depth of the charging head to avoid collision with the inner wall of the crucible, and the stability of the equipment is significantly improved; the buffer bin 33 is divided into multiple independent chambers (such as 5 bins corresponding to 5 crucibles), and the capacity of a single bin matches the crucible charging requirements, supporting flexible adaptation to different kiln car 1 specifications (such as 6 rows × 5 columns or other arrangements); the control system 5 integrates a process parameter database, and quickly switches production tasks by presetting parameters such as charging speed and replenishment threshold to meet the charging requirements of multiple varieties of materials.
