Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy, in particular to a weighing mechanism for a powder metallurgy batching machine. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. Powder metallurgy is similar to the production of ceramics, both of which belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used to prepare ceramic materials. The material utilization rate of powder metallurgy itself is already very high, but the current powder metallurgy batching mechanism needs to weigh the metal powder once before each preparation when configuring different metal powders or configuring the same metal powder multiple times, which is very cumbersome. In view of this, we propose a weighing mechanism for powder metallurgy batching machine. Utility Model Content

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the 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.

[0024] Embodiment 1

[0025] As Figures 1-3As shown in the figure, the utility model provides a weighing mechanism for a powder metallurgy batching machine, which includes a device main body 1. A weighing mechanism 2 is arranged on the device main body 1, and a knocking mechanism 3 is arranged on the weighing mechanism 2. The weighing mechanism 2 includes: a support frame 21, which is fixedly installed on the top of the device main body 1. The inner wall of the top of the support frame 21 is fixedly connected with a first spring 22. The bottom end of the first spring 22 is fixedly connected with a support plate 23. The inside of the support frame 21 is hollow and open on the left side. The support plate 23 is slidably connected with the inner wall of the support frame 21. The left side of the support plate 23 is fixedly connected with a connecting frame 24. A hopper 25 is fixedly connected to the connecting frame 24. The connecting frame 24 is arranged in a "U" shape. The hopper 25 is located in the inner cavity of the connecting frame 24. A control valve is arranged below the inner wall of the hopper 25. An inlet channel is arranged on the top of the device main body 1 and corresponds to the position of the hopper 25. An installation plate 26 is slidably connected with the inner wall of the support frame 21. An inductor 27 is fixedly installed on the top of the installation plate 26. The bottom end of the support plate 23 is fixedly connected with a contact rod 28. The bottom end of the contact rod 28 is fixedly connected with a contact head 29 and is located directly above the inductor 27. By putting metal powder into the hopper 25, the hopper 25 drives the connecting frame 24 to move under the action of gravity. The connecting frame 24 drives the support plate 23 to move, so that the support plate 23 slides along the inner cavity of the support frame 21 and stretches the first spring 22. Thus, the support plate 23 drives the contact rod 28 to move, and the contact rod 28 drives the contact head 29 to move. When the contact head 29 contacts the inductor 27, it is the preset weight of the metal powder. The operation is convenient and greatly saves the measurement time. The knocking mechanism 3 includes: a fixing plate 31, which is fixedly connected to the outer wall of the hopper 25. A micro motor 32 is fixedly installed on the right side of the fixing plate 31. The output end of the micro motor 32 is fixedly connected with a rotating shaft 33 through a coupling. The right end of the rotating shaft 33 is fixedly connected with a sleeve 34. The inner wall of the sleeve 34 is fixedly connected with a second spring 35. The front end of the second spring 35 is fixedly connected with a rubber ball 36. By starting the micro motor 32 to drive the rotating shaft 33 to rotate, the rotating shaft 33 drives the sleeve 34 to rotate. The sleeve 34 drives the second spring 35 to rotate, and the second spring 35 drives the rubber ball 36 to rotate. Thus, the rubber ball 36 continuously knocks the outer wall of the hopper 25, so that the hopper 25 vibrates, which is convenient for the metal powder to be discharged and avoids the metal powder from adhering to the outer wall of the hopper 25, thus avoiding waste.

[0026] In this embodiment, by putting metal powder into the hopper 25, the hopper 25 drives the connecting frame 24 to move under the action of gravity. The connecting frame 24 drives the support plate 23 to move, so that the support plate 23 slides along the inner cavity of the support frame 21 and stretches the first spring 22. Thus, the support plate 23 drives the contact rod 28 to move, and the contact rod 28 drives the contact head 29 to move. When the contact head 29 contacts the inductor 27, it is the preset weight of the metal powder. The operation is convenient and greatly saves the measurement time. By starting the micro motor 32 to drive the rotating shaft 33 to rotate, the rotating shaft 33 drives the sleeve 34 to rotate, the sleeve 34 drives the second spring 35 to rotate, and the second spring 35 drives the rubber ball 36 to rotate. Thus, the rubber ball 36 continuously knocks on the outer wall of the hopper 25, so that the hopper 25 vibrates, which is convenient for the metal powder to be discharged and avoids the adhesion of the metal powder to the outer wall of the hopper 25, thus avoiding waste.

By starting the electric telescopic rod 4 to drive the mounting plate 26 to slide along the inner cavity of the support frame 21, the mounting plate 26 drives the inductor 27 to move, so that the position of the inductor 27 can be adjusted as needed, which is convenient for weighing metal powders of different weights and improves the practicability.

[0029] In this embodiment, by starting the electric telescopic rod 4 to drive the mounting plate 26 to slide along the inner cavity of the support frame 21, the mounting plate 26 drives the inductor 27 to move, so that the position of the inductor 27 can be adjusted as needed, which is convenient for weighing metal powders of different weights and improves the practicability.

[0030] Next, the working principle of the weighing mechanism of the powder metallurgy batching machine will be specifically described.

[0031] As Figures 1-3As shown, when in use, by putting metal powder into the hopper 25, the hopper 25 drives the connecting frame 24 to move under the action of gravity. The connecting frame 24 drives the support plate 23 to move, so that the support plate 23 slides along the inner cavity of the support frame 21 and stretches the first spring 22, thereby causing the support plate 23 to drive the contact rod 28 to move, and the contact rod 28 drives the contact head 29 to move. When the contact head 29 contacts the inductor 27, it is the preset weight of the metal powder. By opening the control valve, the discharge port of the hopper 25 is opened, and the metal powder can be discharged. By starting the micro motor 32 to drive the rotating shaft 33 to rotate, the rotating shaft 33 drives the sleeve 34 to rotate, the sleeve 34 drives the second spring 35 to rotate, and the second spring 35 drives the rubber ball 36 to rotate, so that the rubber ball 36 continuously knocks on the outer wall of the hopper 25, thereby vibrating the hopper 25 to prevent the metal powder from adhering to the outer wall of the hopper 25; By starting the electric telescopic rod 4 to drive the mounting plate 26 to slide along the inner cavity of the support frame 21, the mounting plate 26 drives the inductor 27 to move, so that the position of the inductor 27 can be adjusted as needed, facilitating the weighing of metal powders of different weights.
