Description

Technical Field

[0001] This application relates to the technical field of mixing of metal powder raw materials, and specifically relates to a metal material mixing and batching device. Background Art

[0002] When manufacturing typical industrial products such as metal materials and composite materials, powder metallurgy is usually used to sinter metal materials. At the same time, powder metallurgy technology has been applied in fields such as transportation, machinery, electronics, aerospace, weapons, biology, new energy, information, and nuclear industry, and has become one of the most dynamic branches in new material science. Powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high product precision, and good stability, and is suitable for mass production.

[0003] Powder metallurgy mainly includes several steps such as powder making, mixing, forming, and sintering. After the powder making operation of metal materials, the metal powder needs to be mixed. Pour various required metal powders into a double-cone mixer and perform mixing and stirring in the double-cone mixer to make different types of metal powders uniformly mixed in the double-cone mixer. After mixing, pour the metal powder into a forming mold for forming treatment.

[0004] Referring to the Chinese patent document with the publication number CN107321996B and the name of metal powder airtight continuous post-treatment device, this device realizes the airtightness of the post-treatment device through the airtight soft connection between different process equipment, and enables the materials in the drying device to be automatically transported to the screening machine through the automatic docking device and the rotary feeder.

[0005] For the above technical solution, the existing double-cone mixer usually uses a flap mechanism to control the feeding port and the discharging port. When using the double-cone mixer to mix metal materials, the mixing chamber in the double-cone mixer needs to be rotated 360 degrees. During the rotation of the mixing chamber, the metal materials will move towards the feeding port or the discharging port under the action of gravity. When the double-cone mixer operates for a long time, the metal materials are likely to damage the flap mechanism at the feeding port or the discharging port under the action of gravity, destroying the airtight state in the double-cone mixer and affecting the quality of the mixed metal materials. At the same time, due to the relatively definite moving direction of the materials inside the double-cone mixer, some metal materials may be unevenly mixed. Summary of the Invention

[0006] In view of this, this application provides a metal material mixing and batching device, aiming to solve the problem that the impact force on the feeding port and the discharging port is too large when the double-cone mixer rotates, resulting in the contact between metal powder and air.

[0007] A metal material mixing and batching device provided by the present application adopts the following technical solutions, including a support frame, a double-cone mixing cylinder rotatably connected to the support frame, a rotating mechanism for driving the double-cone mixing cylinder to rotate, a feeding end and a discharging end for adding and discharging materials respectively arranged at both ends of the double-cone mixing cylinder, and a flap mechanism for controlling the entry or exit of materials is arranged at both ends of the double-cone mixing cylinder; the flap mechanism includes a rotating motor fixedly connected to the double-cone mixing cylinder, a crankshaft fixedly connected to the output shaft of the rotating motor, a sliding rod rotatably connected to the crankshaft, the sliding rod is slidably connected to the double-cone mixing cylinder, a first conical plate for dispersing the added materials is fixedly connected to one end of the sliding rod close to the feeding end, a sealing block is fixedly connected to one end of the sliding rod close to the discharging end, and the first conical plate and the sealing block are used to reduce the impact of metal materials on the feeding end and the discharging end.

[0008] By strengthening the sealing state of the feeding end and the discharging end, the impact force generated during the flipping of metal materials can be reduced, thereby reducing the wear of the double-cone mixing cylinder, prolonging the service life of the double-cone mixing cylinder, and at the same time enabling both ends of the double-cone mixing cylinder to withstand greater material impact, reducing the probability of metal materials contacting and oxidizing with air due to excessive impact force of the materials.

[0012] Driven by the mixing auger, the materials on both sides of the double-cone mixing cylinder move towards the middle position of the double-cone mixing cylinder, enabling the materials to be more evenly distributed in the mixing cylinder, thereby improving the mixing uniformity. At the same time, the mixing dead angle of the double-cone mixing cylinder can be reduced, making it difficult for materials to accumulate in the corners, and improving the utilization efficiency of the double-cone mixing cylinder.

[0013] Optionally, a transmission bevel gear is fixedly connected to the rotating rod, and mixing bevel gears are respectively meshed on both sides of the transmission bevel gear, and mixing rods are respectively fixed on the two mixing bevel gears.

[0014] Optionally, a second conical plate is fixedly connected to the mixing rod on the side close to the feeding end, and the second conical plate is used to assist in dispersing the materials entering the double-cone mixing cylinder.

[0015] By driving the second conical plate to rotate, the materials can be mixed in the vertical direction, so that the materials can move in multiple directions, greatly improving the mixing efficiency.

[0016] Optionally, a plurality of material leakage holes are formed in the second conical plate, and the material leakage holes are used to help disperse the metal materials on the second conical plate.

Detailed Embodiment

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below in conjunction with the Figures 1 - 5 of the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. Based on the described embodiments of this application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by this application.

[0031] As Figure 1 and Figure 2As shown in the figure, this embodiment provides a metal material mixing and batching device, which includes a support frame 1, a double-cone mixing cylinder 11 rotatably connected to the support frame 1, a rotating mechanism 2, a flap mechanism 3, a mixing mechanism, and a transmission mechanism. Feed ends 12 for adding materials and discharge ends 13 for discharging materials are respectively provided at both ends of the double-cone mixing cylinder 11. The rotating mechanism 2 is arranged on the support frame 1 and is used to drive the double-cone mixing cylinder 11 to rotate. The flap mechanism 3 is arranged at the feed end 12 and the discharge end 13 of the double-cone mixing cylinder 11 to keep the feed end 12 and the discharge end 13 of the double-cone mixing cylinder 11 airtight. The mixing mechanism is arranged inside the double-cone mixing cylinder 11 to facilitate the movement of the materials inside the double-cone mixing cylinder 11 and improve the mixing efficiency. The transmission mechanism is used to drive the mixing mechanism to rotate.

[0032] As Figure 2 shown, the rotating mechanism 2 includes a turning motor 21 and a rotating block 22. The turning motor 21 is fixedly connected to the support frame 1, the rotating block 22 is fixedly connected to the output shaft of the turning motor 21, and the rotating block 22 is fixedly connected to the double-cone mixing cylinder 11. When it is necessary to drive the double-cone mixing cylinder 11 to rotate, start the turning motor 21. The output shaft of the turning motor 21 rotates to drive the rotating block 22 to rotate, and the rotating block 22 rotates to drive the double-cone mixing cylinder 11 to rotate.

[0033] Since the volumes of the double-cone mixing cylinders 11 used are different, the required power of the turning motors 21 is also different. When the production capacity of the double-cone mixing cylinder 11 is 120 liters, the power of the turning motor 21 is 3 Kw, the rotation speed is 20 R / min, the rotation speed of the material bucket is 12 rpm, and the rotation speed of the mixing auger 44 is 42 rpm. When the production capacity of the double-cone mixing cylinder 11 is 200 liters, the power of the turning motor 21 is 5.5 Kw, the rotation speed is 20 R / min, the rotation speed of the material bucket is 12 rpm, and the rotation speed of the mixing auger 44 is 28 rpm.

[0034] As Figure 2 、 Figure 3 and Figure 4As shown in the figure, the flap mechanism 3 includes a rotating motor 31, a crankshaft 32, a sliding rod 33, a first conical plate 34, a sealing block 35 and a sealing flap 36. The rotating motor 31 is fixedly connected to the double-cone mixing cylinder 11. The crankshaft 32 is fixedly connected to the output shaft of the rotating motor 31. The sliding rod 33 is rotatably connected to the crankshaft 32 and is slidably connected to the double-cone mixing cylinder 11. The first conical plate 34 is fixedly connected to one end of the sliding rod 33 extending into the double-cone mixing cylinder 11, and the first conical plate 34 is arranged at one end of the double-cone mixing cylinder 11 close to the feeding end 12. The first conical plate 34 is used to disperse the materials added to the double-cone mixing cylinder 11. The sealing block 35 is fixedly connected to one end of the sliding rod 33 extending into the double-cone mixing cylinder 11, and the sealing block 35 is arranged at one end of the double-cone mixing cylinder 11 close to the discharging end 13. The sealing block 35 and the first conical plate 34 are used to reduce the impact of metal materials on the feeding end 12 and the discharging end 13. The sealing flap 36 is fixedly connected to the crankshaft 32, and in this embodiment, there are two sealing flaps 36, and the two sealing flaps 36 are respectively arranged at the feeding end 12 and the discharging end 13.

[0035] When it is necessary to add metal materials into the double-cone mixing cylinder 11, start the rotating motor 31. The output shaft of the rotating motor 31 rotates, driving the crankshaft 32 to rotate. The rotation of the crankshaft 32 drives the sealing flap 36 to rotate, so that the sealing flap 36 at the feeding end 12 rotates, and then the feeding end 12 can communicate with the external storage bin, enabling the metal materials to be introduced into the double-cone mixing cylinder 11. After the crankshaft 32 rotates, the sliding rod 33 located on the crankshaft 32 moves towards the end extending into the double-cone mixing cylinder 11 under the drive of the crankshaft 32. After the sealing flap 36 is opened, the materials are introduced from the feeding end 12. The materials move from the outside of the first conical plate 34 into the double-cone mixing cylinder 11. And under the influence of the shape of the first conical plate 34, the metal materials entering the double-cone mixing cylinder 11 are dispersed, which is convenient for subsequent mixing. And after the materials are introduced, the output shaft of the rotating motor 31 continues to rotate, driving the crankshaft 32 to rotate. The rotation of the crankshaft 32 drives the sealing flap 36 to close the feeding end 12 and the discharging end 13. At this time, the sliding rod 33 moves towards the end away from the inside of the double-cone mixing cylinder 11, so that the outer wall of the first conical plate 34 abuts against the inner wall of the double-cone mixing cylinder 11. At this time, the outer wall of the sealing block 35 abuts against the inner wall of the double-cone mixing cylinder 11 to seal the inside of the double-cone mixing cylinder 11.

[0036] As Figure 2 and Figure 3As shown in the figure, the transmission mechanism includes a rotating bevel gear 4, a driven bevel gear 41, a mixing bevel gear 42, a rotating rod 43, and a mixing auger 44. The rotating bevel gear 4 is fixedly connected to the rotating block 22 on the side of the double-cone mixing drum 11 away from the tilting motor 21, and the rotating bevel gear 4 is arranged inside the support frame 1. The driven bevel gear 41 is rotatably connected to the support frame 1, and the driven bevel gear 41 can mesh with the rotating bevel gear 4. The mixing bevel gear 42 is rotatably connected to the support frame 1, and the mixing bevel gear 42 can mesh with the driven bevel gear 41. The rotating rod 43 is fixedly connected to the mixing bevel gear 42, and the rotating rod 43 extends into the double-cone mixing drum 11. The mixing auger 44 is fixedly connected to the rotating rod 43, and the mixing auger 44 is used to drive the metal materials located in the double-cone mixing drum 11 to move towards the middle position of the double-cone mixing drum 11.

[0037] When the materials are mixed into the double-cone mixing drum 11 and the tilting motor 21 is started, the double-cone mixing drum 11 rotates to drive the rotating block 22 to rotate. The rotating block 22 rotates to drive the rotating bevel gear 4 to rotate. The rotating bevel gear 4 rotates to drive the driven bevel gear 41 to rotate. The driven bevel gear 41 rotates to drive the mixing bevel gear 42 to rotate. The mixing bevel gear 42 rotates to drive the rotating rod 43 to rotate. The rotating rod 43 rotates to drive the mixing auger 44 to rotate. The mixing auger 44 rotates to drive the metal materials located on both sides of the double-cone mixing drum 11 to move towards the middle position of the double-cone mixing drum 11, accelerating the mixing between the metal materials.

[0038] As Figure 4 and Figure 5 shown in the figure, the mixing mechanism includes a driving bevel gear 5, a mixing bevel gear 51, a mixing rod 52, a second conical plate 53, and a spiral stirring blade 55. The driving bevel gear 5 is fixedly connected to the rotating rod 43. In this embodiment, there are two mixing bevel gears 51. The two mixing bevel gears 51 are respectively meshed with the driving bevel gear 5 and can rotate under the drive of the driving bevel gear 5. The mixing rod 52 is fixedly connected to the mixing bevel gear 51, and a second conical plate 53 is fixedly connected to the mixing rod 52 near the feeding end 12. The second conical plate 53 is used to assist in mixing the impurities located in the double-cone mixing drum 11. Leakage holes 54 for helping mixing are provided on the second conical plate 53. The spiral stirring blade 55 is fixedly connected to the mixing rod 52 near the discharging end 13. The spiral stirring blade 55 is used to drive the metal materials located in the double-cone mixing drum 11 to be mixed.

[0039] When the rotating rod 43 rotates, it drives the transmission bevel gear 5 to rotate. The transmission bevel gear 5 drives the mixing bevel gear 51 to rotate, and the mixing bevel gear 51 drives the mixing rod 52 to rotate. The rotation of the mixing rod 52 drives the second conical plate 53 and the spiral stirring blades 55 to rotate. When the feeding end 12 of the double-cone mixing cylinder 11 is at one end close to the horizontal plane, the metal material drops into the interior of the second conical plate 53 and falls through the material leakage holes 54 to the first conical plate 34, and moves towards the discharging end 13 during the continuous flipping process. When the discharging end 13 of the double-cone mixing cylinder 11 is at one end close to the horizontal plane, the metal material drops onto the spiral stirring blades 55, and the material located on the spiral stirring blades 55 is dispersed and mixed during the rotation of the mixing rod 52.

[0040] When this application is in use, start the rotating motor 31. The output shaft of the rotating motor 31 rotates, driving the crankshaft 32 to rotate. The rotation of the crankshaft 32 drives the sealing flap 36 to rotate, causing the sealing flap 36 at the feeding end 12 to rotate, so that the feeding end 12 can communicate with the external storage bin, enabling the metal material to enter the double-cone mixing cylinder 11. After the crankshaft 32 rotates, the sliding rod 33 on the crankshaft 32 moves towards the end extending into the double-cone mixing cylinder 11 under the drive of the crankshaft 32. When the sealing flap 36 is opened, the material enters from the feeding end 12, and the material moves from the outside of the first conical plate 34 to the inside of the double-cone mixing cylinder 11. Under the influence of the shape of the first conical plate 34, the metal material entering the inside of the double-cone mixing cylinder 11 is dispersed, facilitating subsequent mixing.

[0041] After the material enters, the output shaft of the rotating motor 31 continues to rotate, driving the crankshaft 32 to rotate. The rotation of the crankshaft 32 drives the sealing flap 36 to close the feeding end 12 and the discharging end 13. At this time, the sliding rod 33 moves towards the end away from the inside of the double-cone mixing cylinder 11, causing the outer wall of the first conical plate 34 to abut against the inner wall of the double-cone mixing cylinder 11. At this time, the outer wall of the sealing block 35 abuts against the inner wall of the double-cone mixing cylinder 11 to seal the inside of the double-cone mixing cylinder 11.

[0042] Start the flipping motor 21. The rotation of the double-cone mixing cylinder 11 drives the rotating block 22 to rotate. The rotation of the rotating block 22 drives the rotating bevel gear 4 to rotate. The rotation of the rotating bevel gear 4 drives the driven bevel gear 41 to rotate. The rotation of the driven bevel gear 41 drives the stirring bevel gear 42 to rotate. The rotation of the stirring bevel gear 42 drives the rotating rod 43 to rotate. The rotation of the rotating rod 43 drives the mixing auger 44 to rotate. The rotation of the mixing auger 44 drives the metal materials on both sides of the double-cone mixing cylinder 11 to move towards the middle position of the double-cone mixing cylinder 11, accelerating the mixing between the metal materials.

[0043] When the rotating rod 43 rotates, it drives the transmission bevel gear 5 to rotate. The transmission bevel gear 5 drives the mixing bevel gear 51 to rotate, and the mixing bevel gear 51 drives the mixing rod 52 to rotate. The rotation of the mixing rod 52 drives the second conical plate 53 and the spiral stirring blades 55 to rotate. When the feeding end 12 of the double-cone mixing cylinder 11 is at one end close to the horizontal plane, the metal material drops into the interior of the second conical plate 53 and falls through the material leakage holes 54 to the first conical plate 34, and moves towards the discharging end 13 during the continuous flipping process. When the discharging end 13 of the double-cone mixing cylinder 11 is at one end close to the horizontal plane, the metal material drops onto the spiral stirring blades 55, and the material located on the spiral stirring blades 55 is dispersed and mixed during the rotation of the mixing rod 52.

[0044] In this embodiment, strengthening the sealing state of the feeding end 12 and the discharging end 13 can reduce the impact force generated by the metal material during flipping, thereby reducing the wear of the mixing cylinder, extending the service life of the equipment, and enabling both ends of the double-cone mixing cylinder 11 to withstand greater impact forces of the material, reducing the probability of oxidation of the metal material due to contact with air caused by impact.

[0045] In this embodiment, driven by the mixing auger 44, the materials on both sides of the double-cone mixing cylinder 11 move towards the middle position of the double-cone mixing cylinder 11, enabling the materials to be more evenly distributed in the mixing cylinder, thereby improving the mixing uniformity. At the same time, it can reduce the mixing dead corners of the double-cone mixing cylinder 11, making it difficult for the materials to accumulate in the corners and improving the utilization efficiency of the double-cone mixing cylinder 11.

[0046] In this embodiment, by pushing the materials from the bottom and the side towards the center position of the mixing cylinder and driving the dispersion of the metal materials during rotation, the mixing uniformity of the materials is improved. At the same time, the spiral stirring blades 55 can drive the metal materials to move axially and radially, and the rotation of the second conical plate 53 drives the materials to be mixed in the vertical direction, thereby enabling the materials to be stirred in multiple directions and greatly improving the mixing efficiency.

[0047] In the embodiment of the present application, the implementation principle of a metal material mixing and batching device is as follows: Start the rotating motor 31. The output shaft of the rotating motor 31 rotates, driving the crankshaft 32 to rotate. The rotation of the crankshaft 32 drives the sealing flap 36 to rotate, causing the sealing flap 36 at the feeding end 12 to rotate, so that the feeding end 12 can communicate with the external storage bin, enabling the metal material to be introduced into the double-cone mixing cylinder 11. When the crankshaft 32 rotates, the sliding rod 33 on the crankshaft 32 moves towards the end extending into the double-cone mixing cylinder 11 under the drive of the crankshaft 32. When the sealing flap 36 is opened, the material is introduced from the feeding end 12. The material moves from the outside of the first conical plate 34 to the inside of the double-cone mixing cylinder 11. And under the influence of the shape of the first conical plate 34, the metal material entering the inside of the double-cone mixing cylinder 11 is dispersed, facilitating subsequent mixing.

[0048] After the material is introduced, the output shaft of the rotating motor 31 continues to rotate, driving the crankshaft 32 to rotate. The rotation of the crankshaft 32 drives the sealing flap 36 to close the feeding end 12 and the discharging end 13. And at this time, the sliding rod 33 moves towards the end away from the inside of the double-cone mixing cylinder 11, making the outer wall of the first conical plate 34 abut against the inner wall of the double-cone mixing cylinder 11. At this time, the outer wall of the sealing block 35 abuts against the inner wall of the double-cone mixing cylinder 11, sealing the inside of the double-cone mixing cylinder 11.

The rotation of the driven bevel gear 41 drives the stirring bevel gear 42 to rotate. The rotation of the stirring bevel gear 42 drives the rotating rod 43 to rotate. The rotation of the rotating rod 43 drives the mixing auger 44 to rotate. The rotation of the mixing auger 44 drives the metal materials on both sides of the double-cone mixing cylinder 11 to move towards the middle position of the double-cone mixing cylinder 11, accelerating the mixing between the metal materials.

[0050] When the rotating rod 43 rotates, it drives the transmission bevel gear 5 to rotate. The transmission bevel gear 5 drives the mixing bevel gear 51 to rotate. The mixing bevel gear 51 drives the mixing rod 52 to rotate. The rotation of the mixing rod 52 drives the second conical plate 53 and the spiral stirring blades 55 to rotate. When the feeding end 12 of the double-cone mixing cylinder 11 is at the end close to the horizontal plane, the metal material drops into the inside of the second conical plate 53 and falls through the leakage holes 54 to the first conical plate 34, and moves towards the discharging end 13 during the continuous flipping process. When the discharging end 13 of the double-cone mixing cylinder 11 is at the end close to the horizontal plane, the metal material drops onto the spiral stirring blades 55, and the rotation of the mixing rod 52 drives the material on the spiral stirring blades 55 to be dispersed and mixed.
