Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a metal powder packaging device with quantitative feeding function, comprising:

[0026] The barrel body 1, the cover body 2, the anti-caking component 3, and the feeding mechanism 4 are provided. The cover body 2 is threadedly installed at the top opening of the barrel body 1. The bottom of the cover body 2 is provided with the anti-caking component 3, which is used to stir the metal powder in the barrel body 1 to achieve agglomeration and breakup. The feeding mechanism 4 is installed at the bottom outlet of the barrel body 1 to achieve quantitative feeding.

[0027] The feeding mechanism 4 includes a feeding pipe 41, an upper plate 42, a ring 43 and a storage component 44. The feeding pipe 41 is connected to the discharge port at the bottom of the barrel 1. The bottom of the discharge pipe passes through the bottom of the upper plate 42 and extends therethrough. The ring 43 is fixed to the bottom of the upper plate 42 and has a storage component 44 inside, which is used to quantitatively store the metal powder discharged from the feeding pipe 41.

[0028] Specifically, a feeding mechanism 4 is installed at the feeding pipe 41 at the bottom of the barrel 1, which can put metal powder into the storage tank 442 and fill the storage tank 442. The volume of the storage tank 442 is fixed, and excess powder is removed by scraping the top of the storage tank through the bottom edge of the feeding pipe 41, so that the feeding amount is strictly consistent each time. The amount of metal powder fed into the storage tank 442 each time is the same. The multiple storage tanks 442 on the rotating disk 441 can be used in a cycle, which can realize batch and continuous feeding.

[0029] The storage component 44 includes a rotating disk 441, a storage trough 442, a base 443, and a discharge port 444. The rotating disk 441 is rotatably installed inside the ring 43 and has several evenly distributed storage troughs 442 inside. The base 443 has a discharge port 444 for discharging materials from a single storage trough 442. The base 443 is fixed inside the ring 43 and its top is attached to the bottom of the rotating disk 441.

[0030] Furthermore, when the rotating disk 441 rotates, the storage tank 442 will be filled by passing through the bottom of the feeding pipe 41 in sequence, and then rotate to the feeding port 444 to complete the unloading. With the help of the rotation of the rotating disk 441, the storage tank 442 can be recycled, achieving the purpose of continuous quantitative feeding and effectively improving the feeding efficiency.

[0031] The bottom of the feeding pipe 41 is in contact with the top of the rotating disk 441, and the storage groove 442 is smaller than the bottom opening of the feeding pipe 41;

[0032] It is worth noting that the metal powder falls from the feeding pipe 41 into the storage tank 442. During the rotation of the rotating disk 441, the bottom edge of the feeding pipe 41 will scrape the powder on the top of the storage tank 442 to ensure that the metal powder in each storage tank 442 can be accurately quantified, avoiding overfilling.

[0033] An arc-shaped baffle 5 is fixedly installed on one side of the inner wall of the ring 43. The bottom of the arc-shaped baffle 5 is in contact with the top of the rotating disk 441, and is used to push the metal powder remaining on the top of the rotating disk 441 into the storage tank 442.

[0034] It should be noted that when the rotating disk 441 rotates, the arc-shaped baffle 5 collects the metal powder remaining on the top of the rotating disk 441 and pushes it into the storage tank 442, reducing the waste of metal powder and preventing the residual powder from causing adverse effects on the operation of the equipment, such as jamming the rotating disk 441, thus extending the service life of the equipment.

[0035] A wrench 6 is fixedly installed at the bottom of the rotating disk 441, and a circular groove for installing the wrench 6 is provided at the center of the chassis 443.

[0036] The operator can manually turn the wrench 6 to drive the rotating disk 441 to rotate within the ring body 43, providing a simple, direct and easy-to-operate way to rotate the rotating disk 441, reducing the difficulty of operating the equipment, and allowing the operator to control the feeding process more conveniently. In addition, a limit ring is fixedly installed on the surface of the rotating disk 441, which is located in the annular groove on the inner wall of the ring body 43 to limit the rotation of the rotating disk 441.

[0037] The anti-caking component 3 includes a stirrer 31, a gear 32, a rack 33, and an elastic element 34. The upper end of the stirrer 31 is rotatably installed inside the cover body 2, and the gear 32 is fixedly installed on its surface. The cover body 2 is provided with a rack 33 that meshes with the gear 32. The cover body 2 is provided with an elastic element 34 for the rack 33 to rebound. The top of the rack 33 is provided with a protrusion, and the protrusion is slidably installed on the top of the cover body 2.

[0038] Specifically, pushing the protrusion causes the rack 33 to move, and the meshing of the rack 33 with the gear 32 drives the agitator 31 to rotate. After releasing the protrusion, the elastic element 34 causes the rack 33 to spring back, thereby causing the agitator 31 to rotate in the opposite direction. The forward and reverse rotation of the agitator 31 can fully stir the metal powder in various positions in the barrel, effectively break up powder clumps, and ensure that the metal powder is always in a loose state, which is convenient for subsequent feeding operations.

[0039] A guide rod 7 is slidably installed inside the rack 33, and the guide rod 7 is fixedly installed inside the cover 2;

[0040] Furthermore, during the movement of the rack 33, the guide rod 7 provides guidance, ensuring that the rack 33 moves smoothly along the predetermined direction, improving the stability and accuracy of the rack 33's movement, thereby ensuring that the gear 32 can accurately drive the stirrer 31 to rotate, and enhancing the working reliability of the anti-caking component 3.

[0041] The elastic element 34 includes a rod 341, a spring 342 and a sleeve 343. The sleeve 343 is fixed inside the cover 2, and the rod 341 is slidably installed inside it. One end of the rod 341 is fixed to the surface of the toothed rod, and the spring 342 is movably sleeved on the surface of the rod 341.

[0042] When the protrusion is pushed to move the rack 33, the insert rod 341 slides within the sleeve 343 and compresses the spring 342. After the protrusion is released, the spring 342 releases its elastic potential energy, pushing the insert rod 341 and rack 33 back to their original positions, causing the stirrer 31 to rotate in the opposite direction. The elastic deformation of the spring 342 enables the rack 33 to automatically rebound, providing a stable reverse driving force for the stirrer 31. This ensures the continuity and stability of the stirrer 31's forward and reverse rotation, effectively improving the anti-caking effect. Simultaneously, the cooperation between the insert rod 341 and the sleeve 343 guides and protects the spring 342, preventing it from shifting or being damaged during stress, and extending the service life of the elastic element 34.

[0043] This device pours metal powder into the barrel 1 and seals the lid 2 to the opening of the barrel 1. Initially, the bottom opening of the feed pipe 41 is aligned with a storage slot 442. The metal powder in the barrel 1 enters the storage slot 442 through the feed pipe 41. By turning the wrench 6, the rotating disk 441 is rotated, causing the storage slot 442 filled with metal powder to move away from the bottom of the feed pipe 41. During the removal process, the bottom edge of the feed pipe 41 will scrape the top of the storage slot 442 until the next empty storage slot 442 is located at the bottom of the feed pipe 41. The material is then refilled, and the storage slot 442 containing metal powder is rotated to the discharge port 444 in the base plate 443, thereby achieving the discharge of the metal powder. A small amount of metal powder will remain on the top of the rotating disk 441. Due to the setting of the arc-shaped baffle 5, some of the remaining metal powder will be collected by the arc-shaped baffle 5. The rotating disk 441 rotates, which can push the remaining metal powder into the storage tank 442. When it is necessary to break up the metal powder that has clumped inside the barrel 1, the protrusion is pushed to drive the rack 33 to move. The rack 33 meshes with the gear 32. As the rack 33 moves, it drives the gear 32 to rotate, which can control the stirrer 31 to stir the powder inside the barrel 1. The movement of the rack 33 will drive the guide rod 7 to move inside the sleeve 343 and compress the spring 342. When the protrusion is not pushed, the spring 342 deforms, so that the stirrer 31 rotates in the opposite direction.

[0044] 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.
