DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] For example, see Figures 1 to 13 The present invention discloses a powder processing and mixing device for alloy magnetic powder cores, comprising a mixing tank 1, wherein a barrel 11 for mixing and conveying powder is arranged in the mixing tank 1, the barrel 11 is connected to an external powder storage tank through a feeding pipe 12, an air pipe 13 is connected to the bottom of the barrel 11, one end of the air pipe 13 passes through the mixing tank 1 and extends to the outside of the mixing tank 1, and the air pipe 13 is connected to an external air pump.

[0033] In this embodiment, a barrel 11 is provided in the mixing tank 1, and a feed pipe 12 is connected to the outside of the barrel 11. The feed pipe 12 is connected to an external powder storage tank. The powder in different powder storage tanks is transported to the barrel 11 by the feed pipe 12, and the external air pump is started. The air pipe 13 is connected to the external air pump to drive the air flow in the barrel 11 to evenly mix the powder.

[0034] The top of the barrel 11 is connected to a discharge port 14 with a valve, and the discharge port 14 is arranged just below the wheel disc 3 and the blades 4 .

[0035] It should be noted that a pressure valve and a pneumatic delay valve are connected between the discharge port 14 and the barrel 11. The pressure valve is used to balance the pressure inside and outside the barrel 11. The delay valve is started to control the opening time of the discharge port 14 to ensure the length of time for the powder to be initially mixed in the barrel 11.

[0036] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 13 A tank cover 2 is provided on the top of the mixing tank 1, and a motor 8 is fixedly installed at the center position of the tank cover 2. The output shaft end of the motor 8 extends into the mixing tank 1 and is connected to a stirring assembly. The stirring assembly can mix the powder. The stirring assembly includes a wheel disc 3 and blades 4 arranged in an annular array on the outer ring of the wheel disc 3. The wheel disc 3 is fixedly installed on the output shaft end of the motor 8. A material guide groove 5 is provided in the blade 4, and a material collection cavity 6 is provided at one end of the blade 4. A discharge port 7 is provided on one side of the material collection cavity 6, and the discharge port 7 is connected to the material guide groove 5.

[0037] In this embodiment, a stirring assembly is provided at the top of the mixing tank 1 above the barrel 11. When the powder is mixed in the barrel 11 and blown out, the motor 8 is started to drive the wheel disc 3 and the blades 4 on the outer ring of the wheel disc 3 to rotate, and the powder is dispersed and thrown out, so as to facilitate the subsequent further uniform mixing of the powder.

[0038] It should be noted that a material guide groove 5 is provided in the blade 4, and a collecting cavity 6 is provided at one end of the blade 4, and a discharge port 7 is provided on one side of the collecting cavity 6, and the discharge port 7 is connected to the material guide groove 5. After the powder is blown out from the discharge port 14, the powder is collected by the material guide groove 5, and the powder is thrown out through the discharge port 7 by the centrifugal force generated by the rotation of the blade 4, which can not only separate and disperse the powder, but also guide the powder, which is convenient for the subsequent mixing process of the powder.

[0039] The inner wall of the mixing tank 1 is provided with spring pieces 10 in an annular equidistant array between the discharge port 14 and the horizontal position of the blades 4 .

[0040] In this embodiment, there are spring pieces 10 in a circular equidistant array on the inner wall of the mixing tank 1 between the discharge port 14 and the horizontal position of the blades 4. When the powder is thrown out through the discharge port 7, the powder and the spring pieces 10 collide, causing the spring pieces 10 to deform and then reset, bouncing the powder up, further improving the effect of sufficient and uniform mixing between the powder particles.

[0041] It should be noted that in order to prevent the powder from returning to the original path under the bounce of the shrapnel 10, the setting of the discharge port 7 can effectively reduce the situation where the powder is bounced back to the original path; the outlet direction of the discharge port 7 is set to be inclined downward, and the powder moves obliquely downward under the guidance of the discharge port 7 during the process of being thrown out, thereby ensuring the subsequent powder collection effect.

[0042] A material guide hopper 15 is provided in the mixing tank 1. The material guide hopper 15 is provided below the barrel 11, and the discharge port of the material guide hopper 15 is located above the feed port of the collecting seat 16. The bottom of the mixing tank 1 is located below the collecting seat 16 and is connected to a discharge pipe 17 with an electric valve.

[0043] In this embodiment, a guide hopper 15 is provided between the barrel 11 and the collecting seat 16. During the falling process of the powder, the powder smoothly enters the collecting seat 16 through the guide hopper 15 to collect the powder after the above mixing process. After the powders are fully mixed, the electric valve is finally opened, and the fully mixed powders are finally collected through the discharge pipe 17 to complete the powder mixing process.

[0044] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 13 A collecting seat 16 is provided below the barrel 11, and a mixing assembly for mixing powder is provided in the collecting seat 16. The mixing assembly includes a traction rope 21 fixedly connected to the bottom of the barrel 11 and a mixing shaft 20 rotatably connected to the collecting seat 16. The traction rope 21 is fixedly wound around the surface of the mixing shaft 20 at one end away from the barrel 11, and vortex springs 19 are fixedly installed at both ends of the mixing shaft 20. Shaft seats 18 are symmetrically provided on the inner wall of the collecting seat 16. Both ends of the mixing shaft 20 are connected to the shaft seat 18 through vortex springs 19, and a mixing wheel 22 is fixedly installed on the surface of the mixing shaft 20.

[0045] In this embodiment, a mixing shaft 20 is provided in the collecting seat 16, and a mixing wheel 22 is installed on the surface of the mixing shaft 20. At the same time, a traction rope 21 is fixedly wound around the surface of the mixing shaft 20. Since the collecting seat 16 is slidably arranged in the mixing tank 1, as the weight of the powder collected in the collecting seat 16 increases, the collecting seat 16 moves downward. During the downward movement, the mixing shaft 20 is constrained by the traction rope 21 and rotates. During the rotation, the vortex spring 19 is tightened, and the mixing wheel 22 is driven to rotate during the downward movement of the collecting seat 16, so as to further stir the powder, so that the powder of the alloy magnetic powder core is evenly mixed.

[0046] It should be noted that the vortex spring 19 is completely wrapped by the shaft seat 18 to prevent powder from entering the gap of the vortex spring 19 during use and affecting the normal use of the vortex spring 19.

[0047] Specifically, a support plate 34 is fixedly connected to the bottom of the mixing tank 1 through a support rod 40, a guide shaft 35 is slidably connected inside the support plate 34, a bottom support 39 is fixedly connected to the lower part of the collecting seat 16, the guide shaft 35 is fixedly connected to the bottom surface of the bottom support 39, a spring 36 is sleeved on the outer wall of the guide shaft 35, and both ends of the spring 36 are fixedly connected between the bottom support 39 and the support plate 34.

[0048] In this embodiment, a spring 36 is arranged between the base 39 and the support plate 34 arranged at the bottom of the collecting seat 16. When the weight of the powder in the collecting seat 16 increases, the spring 36 is compressed, and the collecting seat 16 moves downward along the guide shaft 35. After the powder is discharged from the collecting seat 16, the return force of the spring 36 drives the collecting seat 16 to move up and reset. When resetting, the vortex spring 19 separates circles, so that the mixing shaft 20 rotates in the opposite direction, and can also drive the mixing wheel 22 to rotate. During the upward movement, the remaining powder is continuously mixed and discharged from the collecting seat 16 to fall into the bottom of the mixing tank 1.

[0049] Example 4: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 13 Guide strips 38 are symmetrically arranged on both sides of the outer wall of the collecting seat 16, a sealing plate 37 is slidably installed in the guide strip 38, the sealing plate 37 and the bottom support 39 are slidably connected, a fourth wedge block 33 is fixedly connected to the bottom of the sealing plate 37, and a third wedge block 32 is fixedly installed on the upper surface of the support rod 40, and the fourth wedge block 33 and the third wedge block 32 are matched.

[0050] In this embodiment, two groups of sealing plates 37 are symmetrically arranged at the bottom of the collecting seat 16. After the collecting seat 16 is filled with powder, the weight increases, so the compression spring 36 moves downward, and when the third wedge block 32 and the fourth wedge block 33 come into contact, the weight continues to increase, and the third wedge block 32 and the fourth wedge block 33 will continue to fit along the slope opened on the fitting surface. Therefore, the two groups of sealing plates 37 are separated under the drive of the fourth wedge block 33, thereby realizing the discharge of powder from the collecting seat 16.

[0051] It should be noted that although powder continues to fall into the collecting seat 16, when the sealing plate 37 is completely opened, the discharge speed of the collecting seat 16 is faster than the feeding speed. Therefore, the total weight of the collecting seat 16 is reduced, and the collecting seat 16 moves up and resets due to the reset force of the spring 36 and the shaft seat 18 and the traction force of the traction rope 21.

[0052] The inner wall of the mixing tank 1 is symmetrically mounted with fixing rods 29, a first wedge block 30 is fixedly mounted at one end of the bottom of the fixing rod 29, a second wedge block 31 is fixedly mounted at one side of the sealing plate 37, and the first wedge block 30 and the second wedge block 31 are matched.

[0053] Based on the above principle, when the collecting seat 16 moves upward, after the second wedge block 31 and the first wedge block 30 are fitted together, the first wedge block 30 is fixedly guided by the slope provided on the fitting surfaces of the first wedge block 30 and the second wedge block 31, and the sealing plate 37 is brought closer, so that the bottom of the collecting seat 16 is closed, and the powder is continuously collected and mixed. Therefore, the function of opening and closing the bottom of the collecting seat 16 is realized during the upward movement / reset of the collecting seat 16, and the powder is continuously stirred during the reciprocating movement of the collecting seat 16, so that the device can perform multiple and sufficient mixing of the powder.

[0054] Example 5: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 13 A pressure valve 9 is arranged in the tank cover 2, a filter screen 23 is arranged in the pressure valve 9, a mesh brush 24 is slidingly arranged on the surface of the filter screen 23, friction blocks 26 are arranged in a circular equidistant array inside the mesh brush 24, the friction blocks 26 and the filter screen 23 are matched, connecting rods 25 are symmetrically arranged on both sides of the mesh brush 24, a connecting plate 28 is fixedly connected to one side of the top of the collecting seat 16, a filter plate 27 is fixedly installed on the bottom of the pressure valve 9, the connecting rod 25 penetrates the filter plate 27 and is fixedly connected to the connecting plate 28.

[0055] In this embodiment, since the external pump body continuously supplies air into the barrel 11, the gas is continuously discharged into the mixing tank 1. Therefore, a pressure valve 9 is provided on the top of the mixing tank 1 to balance the air pressure in the mixing tank 1 and ensure safe operation. The mesh brush 24 and the collecting seat 16 are connected by the connecting plate 28 and the connecting rod 25. During the downward movement / reset of the collecting seat 16, the friction block 26 provided in the mesh brush 24 can be driven to reciprocate in the gap of the filter screen 23 to clean the filter screen 23, thereby preventing the airflow from accumulating powder in the gap of the filter screen 23 during the exhaust process, thereby ensuring the normal use of the pressure valve 9.

[0056] Working principle: During use, the present invention uses the feed pipe 12 to transport the powder in different powder storage tanks into the barrel 11, uses the air pipe 13 to communicate with the external air pump, starts the external air pump to supply air into the barrel 11, uses the air flow to evenly mix the powder, and after a certain period of mixing, discharges it through the discharge port 14; The motor 8 is started to drive the blade 4 to rotate, and the guide groove 5 provided in the blade 4 is used to collect the powder. The centrifugal force generated by the rotation of the blade 4 throws the powder out through the discharge port 7, which can not only separate and scatter the powder, but also guide the powder, which is convenient for the subsequent mixing of the powder. When the powder is thrown out through the discharge port 7, the powder and the spring sheet 10 collide, so that the spring sheet 10 is deformed and reset, and the powder is bounced up, further improving the effect of sufficient and uniform mixing between the powder particles. After the above treatment, the powder falls and enters the collecting seat 16 through the guide hopper 15. As the weight of the powder collected in the collecting seat 16 increases, the collecting seat 16 moves downward. During the downward movement, the mixing shaft 20 drives the mixing wheel 22 to rotate under the constraint of the vortex spring 19 and the traction rope 21, and further stirs the powder, so that the powder of the alloy magnetic powder core is evenly mixed. After the powder is discharged from the collecting seat 16, the spring 36 returns to drive the collecting seat 16 to move upward and reset. When resetting, the spiral spring 19 separates the circles, so that the mixing shaft 20 rotates in the opposite direction, which can also drive the mixing wheel 22 to rotate. During the upward movement, the remaining powder is continuously mixed and discharged from the collecting seat 16 and falls into the bottom of the mixing tank 1. After the powders are fully mixed as described above, the electric valve is opened, and finally the powder mixing process is completed through the discharge pipe 17.

[0057] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
