[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 to 5, a weighing device for alloy mixed powder in this embodiment includes a base 1. A moving device is arranged outside the base 1. A discharging device is arranged above the moving device. A material collecting device is arranged on the side surface of the discharging device. A weighing device is arranged above the base 1. A limiting device is arranged at the side of the base 1 close to the weighing device. The discharging device includes an alloy mixed powder storage box 11 fixedly connected to the upper side of the moving device and a second discharging pipe 13 communicated with the front end surface of the upper side of the alloy mixed powder storage box 11. The material collecting device includes a storage box 14 fixedly connected to the right side of the alloy mixed powder storage box 11, an air suction fan 16 embedded and installed under the storage box 14, a filter plate 15 slidably connected to the inside of the right side of the storage box 14, and a cylinder 17 communicated with the front end surface of the storage box 14. The limiting device includes two columns 2 fixedly connected to the upper side of the base 1, a limiting plate 3 fixedly sleeved outside the columns 2, a movable plate 4 abutted against the upper side of the limiting plate 3, a powder weighing container 5 inserted into the inside of the movable plate 4, a first discharging pipe 8 communicated with the lower end of the right side of the powder weighing container 5, and an adjusting device arranged under the movable plate 4. The adjusting device includes a plurality of supporting structures 6 fixedly connected to the lower side of the movable plate 4 and a second limiting plate 7 fixedly connected to the lower side of the supporting structures 6.

[0028] Among them, the moving device includes a motor 10 fixedly installed on the left side of the base 1, a threaded rod 20 fixedly connected to the output end of the motor 10, a threaded block 21 threadedly connected to the outside of the threaded rod 20, and a slide rod 22 slidably sleeved on the side of the threaded block 21 away from the threaded rod 20. The weighing device includes three electronic scales 9 fixedly installed on the upper side of the base 1. The supporting structure 6 includes a cylinder 17 fixedly connected to the lower side of the movable plate 4, a spring telescopic rod 18 fixedly connected to the inner top wall of the cylinder 17, and a movable sleeve 19 fixedly connected to the lower side of the spring telescopic rod 18. The upper side of the alloy mixed powder storage box 11 is integrally connected with an external thread. The outer wall of the upper side of the alloy mixed powder storage box 11 is threadedly connected with a box cover 12, and the inner wall of the box cover 12 is integrally connected with an internal thread matching the external thread of the alloy mixed powder storage box 11. One side of the cylinder 17 away from the storage box 14 is inserted outside the first discharging pipe 8. A first solenoid valve is arranged on the upper side of the second discharging pipe 13. The supporting structures 6 are divided into three groups in pairs, and the lower side of each group of supporting structures 6 is vertically connected to the edge of the upper side of the second limiting plate 7.

[0029] It should be noted that a through hole penetrating the powder weighing container 5 is opened in the second limiting plate 7 for limiting the middle part outside the powder weighing container 5. A second solenoid valve of the same model as the outside of the second discharging pipe 13 is arranged inside the first discharging pipe 8. The box cover 12 and the alloy mixed powder storage box 11 are fixedly connected by threads. When the second discharging pipe 13 discharges into the powder weighing container 5, it is avoided that dust and impurities enter the alloy mixed powder storage box 11 and contact the powder.

[0030] The working principle of the above embodiment is as follows:

[0031] Pour the powder into the alloy mixing powder storage box 11 and tighten the box cover 12 with internal threads. On the outside of the alloy mixing powder storage box 11, the powder weighing container 5 penetrates through the movable plate 4 and the second limiting plate 7 and is fixed. Then, the movable plate 4 penetrates through the column 2 and abuts against the upper side of the limiting plate 3 and is fixed at the upper end of the electronic scale 9. The motor 10 drives the alloy mixing powder storage box 11 above the threaded block 21 to move above the powder weighing container 5 on the left. Then, one end of the cylinder body 17 is sleeved outside the first discharge pipe 8 and fixed. Open the first solenoid valve of the second discharge pipe 13, and the powder naturally falls into the powder weighing container 5. As the weight increases, the spring telescopic rod 18 extends its own length, and the movable sleeve 19 separates from the outside of the cylinder body 17, driving the second limiting plate 7 and the powder weighing container 5 to contact the upper side of the electronic scale 9 and weighing the weight. When the weight is greater than the set weight, disconnect the first solenoid valve, open the second solenoid valve in the first discharge pipe 8, and start the suction fan 16 to cooperate with the cylinder body 17 to absorb the powder to the upper end of the filter plate 15 in the storage box 14 for collection. Observe the electronic scale 9 again as the powder is lost until the weight is the same as the set weight. Then, close the second solenoid valve, and the motor 10 drives the alloy mixing powder storage box 11 to move above the adjacent powder weighing container 5 again and perform the same operation. During the movement above the adjacent powder weighing container 5, it is necessary to remove the filter plate 15 from the storage box 14 to clean the absorbed dust and reduce the blockage of the filter plate 15 caused by accumulation.
