Technical Field

[0001] This application relates to the technical field of mixing equipment, and in particular to a powder mixing equipment. Background Technology

[0002] Mixing equipment can mix metal powders of different mesh sizes together.

[0003] Currently, Chinese patent CN201855667U discloses a double cone mixer, which includes a tank, a frame separately arranged at both ends of the tank to support the tank, and a tank drive mechanism for driving the tank to rotate relative to the frame. The tank is made of PVC.

[0004] Two metal powders that need to be mixed are placed into a container, and then the drive mechanism is activated. The drive mechanism moves the container, and the two metal powders in the container will mix together. However, the mixing of the two powders can only be achieved by the metal powders tumbling up and down when the container rotates. Since there are adsorption forces between the metal powders, the mixing effect achieved by tumbling alone is not good. Utility Model Content

[0005] To improve the mixing effect, this application provides a powder mixing device.

[0006] This application provides a powder mixing device, which adopts the following technical solution:

[0007] A powder mixing device includes a main body, a mixing tank, and a rotating assembly. The mixing tank is rotatably mounted on the main body via the rotating assembly. A mixing chamber is formed inside the mixing tank. The device also includes a dispersing mechanism, which includes a first dispersing block and a second dispersing block. Both ends of the first dispersing block are connected to the side wall of the mixing chamber. One end of the second dispersing block is connected to the side wall of the mixing chamber, and the other end is located inside the mixing chamber.

[0008] By adopting the above technical solution, two metal powders of different mesh sizes to be mixed are placed in a mixing tank. The rotating component is started, and the rotating component drives the mixing and tumbling to rotate. When the metal powder in the mixing tank is tumbling, the metal powder will collide with the first and second dispersing blocks. The first and second dispersing blocks will break the metal powder apart and then mix it together. The dispersing mechanism can break the metal powder apart, and then the broken metal powder is mixed together, thereby improving the mixing effect.

[0009] Optionally, the vertical cross-sections of both the first and second disintegrating blocks are rhomboid.

[0010] By adopting the above technical solution, the rhomboid shape of the vertical cross section can reduce the phenomenon that metal powder remains on the first and second dispersing blocks when the first and second dispersing blocks disperse the metal powder.

[0011] Optionally, multiple second dispersing blocks are provided, and the multiple second dispersing blocks are not located in the same horizontal plane, and the second dispersing blocks not located in the same horizontal plane have different tilt angles.

[0012] By adopting the above technical solution, when the metal powder impacts the second dispersing block, the direction of movement of the metal powder will change, and the second dispersing block, which is not located on the same horizontal plane and has a different tilt angle, can be dispersed again.

[0013] Optionally, the main body is provided with a collection support mechanism, which includes a support block and a support disk. The support block is disposed on the main body, and the support disk is placed on the support block.

[0014] By adopting the above technical solution, a support plate is placed on a support block, and a collection bucket is placed on the support plate. When the collection bucket is full of metal powder, the metal powder will overflow from the collection bucket and fall onto the support plate. The metal powder on the support plate will be collected later, which can reduce the waste of metal powder. Therefore, the set collection support mechanism can better collect the mixed metal powder.

[0015] Optionally, a positioning component is provided on the main body. The positioning component includes a connecting block and a positioning block. The main body has multiple connecting slots. The connecting block engages with the connecting slots. The positioning block is disposed on the connecting block. The support plate can abut against the positioning block.

[0016] By adopting the above technical solution, the connecting block is snapped into the connecting groove at a suitable position on the main body according to the size of the support plate; then the support plate is placed on the support block and the support plate is made to abut against the positioning block, so that the support plate is in a suitable position on the main body, and the support plate of different sizes can still better handle metal powder.

[0017] Optionally, the connecting block has a cavity and a first sliding hole communicating with the cavity; the connecting block is provided with a reinforcing mechanism, the reinforcing mechanism including a reinforcing block and an adjusting component, the reinforcing block is slidably disposed in the first sliding hole, and a reinforcing groove is formed on the side wall of the connecting groove to engage with the reinforcing block; the adjusting component is disposed on the connecting block and connected to the reinforcing block.

[0018] By adopting the above technical solution, when the connecting block is engaged with the connecting groove, the adjusting component drives the reinforcing block to move, so that the reinforcing block is engaged with the reinforcing groove on the connecting block, thereby improving the stability of the connecting block on the main body, so that the positioning component can better achieve the positioning function.

[0019] Optionally, the connecting block has a second sliding hole communicating with the cavity. The adjusting assembly includes a first rack, a first gear, an adjusting shaft, a second gear, an adjusting block, a second rack, a first spring, and a second spring. The first rack is disposed on the reinforcing block. The adjusting shaft is rotatably disposed within the cavity. The first gear is keyed to the adjusting shaft and meshes with the first rack. The second gear is keyed to the adjusting shaft. The adjusting block is slidably disposed within the second sliding hole. The second rack is disposed on the adjusting block and meshes with the second gear. One end of the first spring is connected to the reinforcing block and the other end is connected to the connecting block. One end of the second spring is connected to the adjusting block and the other end is connected to the connecting block.

[0020] By adopting the above technical solution, before the connecting block enters the connecting groove, the operator first presses the reinforcing block to make it enter the first sliding hole, or pulls the adjusting block. The second rack on the adjusting block drives the second gear to rotate, the second gear drives the adjusting shaft to rotate, the first gear on the adjusting shaft drives the first rack to move, and the first rack drives the reinforcing block to move, making the reinforcing block enter the first sliding hole. When the reinforcing block is in the first sliding hole, both the first spring and the second spring will deform. Then, the connecting block is engaged with the connecting groove. When the connecting block is fully engaged with the connecting groove, the reinforcing block will be aligned with the reinforcing groove. Then, the adjusting block is released, and the force of the first spring and the second spring restoring their elastic deformation drives the reinforcing block to move, making the reinforcing block engage with the reinforcing groove.

[0021] Optionally, a stop block is fixedly provided on the adjusting block located inside the cavity; an auxiliary block is fixedly provided on the adjusting block located outside the cavity.

[0022] By adopting the above technical solution, the auxiliary block can facilitate the operator to adjust the adjusting block, and the stop block limits the range of movement of the adjusting block to reduce the phenomenon of the adjusting block moving out of the second sliding hole.

[0023] Optionally, it also includes a sealing component, which includes a sealing block and a pull ring. The sealing block can engage with the connecting groove, and the pull ring is disposed on the sealing block.

[0024] By adopting the above technical solution, the sealing block is engaged with the connecting groove that is not engaged with the connecting block, reducing the phenomenon of metal powder entering the connecting groove; moreover, the pull block makes it easy to separate the sealing block from the connecting groove.

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a powder mixing device.

[0039] refer to Figure 1 The main body 1 includes a first fixing block 11, a third fixing block is fixedly connected to the first fixing block 11, and a second fixing block 12 is fixedly connected to the end of the third fixing block away from the first fixing block 11. The second fixing block 12 and the first fixing block 11 are arranged in parallel.

[0040] refer to Figure 1 and Figure 2 The rotating assembly 3 includes two rotating shafts 31. One rotating shaft 31 is rotatably mounted on the first fixed block 11, and the other rotating shaft 31 is rotatably mounted on the second fixed block 12. The axes of the two rotating shafts 31 coincide, and both rotating shafts 31 are connected to the mixing tank 2. A rotating motor 32 is fixedly connected to the first fixed block 11. A drive gear 33 is keyed to the output shaft of the rotating motor 32, and a driven gear 34 that meshes with the drive gear 33 is keyed to the rotating shaft 31 located on the first fixed block 11.

[0041] Start the rotating motor 32, which drives the driving gear 33 to rotate. The driving gear 33 drives the driven gear 34 to rotate. The driven gear 34 drives the rotating shaft 31 on the first fixed block 11 to rotate. This rotating shaft 31 drives the mixing tank 2 to rotate. The mixing tank 2 drives another rotating shaft 31 to rotate on the second fixed block 12.

[0042] refer to Figure 1 and Figure 2 The mixing tank 2 has a mixing chamber 21 inside. One end of the mixing tank 2 is the feeding end, and a feeding port communicating with the mixing chamber 21 is formed on the feeding end. A cover with a threaded connection or a clamp connection is provided on the feeding end. The end of the mixing tank 2 away from the feeding end is the discharging end, and a discharging port communicating with the mixing chamber 21 is formed on the discharging end. A switch valve, such as a butterfly valve, is provided at the position of the discharging port.

[0043] A dispersing mechanism 4 is provided on the mixing tank 2. The dispersing mechanism 4 includes a first dispersing block 41 located inside the mixing chamber 21. Both ends of the first dispersing block 41 are connected to the mixing tank 2, that is, both ends of the first dispersing block 41 are connected to the side wall of the mixing chamber 21. A second dispersing block 42 is also fixed inside the mixing tank 2. The second dispersing block 42 is located inside the mixing chamber 21, and the end of the second dispersing block 42 away from the mixing tank 2 points to the central axis of the mixing tank 2, that is, one end of the second dispersing block 42 is connected to the side wall of the mixing chamber 21. When the discharge port of the mixing tank 2 is vertically downward, the vertical cross-section of both the first dispersing block 41 and the second dispersing block 42 is rhomboid. There are multiple second dispersing blocks 42, and the multiple second dispersing blocks 42 are not located on the same horizontal plane, and the angles of inclination of the multiple second dispersing blocks not located on the same horizontal plane are different.

[0044] The metal powder to be mixed is fed into the mixing chamber 21 through the feed inlet, and then the cover is attached to the mixing tank 2 to seal the feed inlet. When the rotating shaft 31 rotates, the tumbling mixing tank 2 causes the metal powder in the mixing chamber 21 to tumble. The tumbling metal powder will collide with the first dispersing block 41 and the second dispersing block 42. The first dispersing block 41 and the second dispersing block 42 disperse the tumbling metal powder and then gather it together, thereby improving the mixing effect.

[0045] refer to Figure 1 and Figure 3 The collection support mechanism 5 includes two support blocks 51, one of which is fixedly connected to the first fixed block 11, and the other support block 51 is fixedly connected to the second fixed block 12; the two support blocks 51 together support a support disk 52.

[0046] refer to Figure 3 and Figure 4Both the first fixing block 11 and the second fixing block 12 are provided with connecting grooves 121, which are located at the end of the support block 51 away from the rotating shaft 31. Both the first fixing block 11 and the second fixing block 12 are provided with positioning components 6. The positioning components 6 include connecting blocks 61 that engage with the connecting grooves 121. A positioning block 62 is fixedly connected to the connecting block 61, and the end of the positioning block 62 away from the connecting block 61 is located between the support block 51 and the rotating shaft 31.

[0047] Engage the end of the connecting block 61 away from the positioning block 62 with the connecting groove 121 on the first fixing block 11 and the second fixing block 12, so that the positioning block 62 is connected to both the first fixing block 11 and the second fixing block 12; then place the support plate 52 on the two support blocks 51 and make the support plate 52 abut against the positioning block 62 on the first fixing block 11 and the second fixing block 12. After the metal powder is mixed in the mixing tank 2, the collection bucket containing the mixed metal powder is placed on the support plate 52. Then, the valve is opened, allowing the mixed metal powder to fall into the collection bucket through the discharge port in the mixing chamber 21. If the metal powder is flowing out of the discharge port and the collection bucket is not directly below the discharge port, the position of the collection bucket needs to be adjusted so that it is directly below the discharge port. The metal powder flowing out of the discharge port will then fall onto the support plate 52. Alternatively, when the metal powder overflows from the collection bucket, the overflowing metal powder will fall onto the support plate 52. Later, the operator will move the support plate 52, which is located on the support block 51, out and collect the mixed metal powder on the support plate 52.

[0050] refer to Figure 4 and Figure 5The connecting block 61 has a cavity 611, a first sliding hole communicating with the cavity 611, and a second sliding hole communicating with the cavity 611. Both the first fixing block 11 and the second fixing block 12 have reinforcing grooves communicating with the connecting groove 121. The connecting block 61 is provided with a reinforcing mechanism 7, which includes a reinforcing block 71 slidably connected within the first sliding hole. One end of the reinforcing block 71 is located within the cavity 611, and the other end can engage with the reinforcing groove. An adjusting component 72 is provided on the connecting block 61. The adjusting component 72 includes a first rack 721 integrally mounted on the reinforcing block 71, located within the cavity 611. A fourth fixing block 729 is fixedly connected to the connecting block 61, located within the cavity 611. An adjusting shaft 723 is rotatably connected to the fourth fixing block 729. One end of the adjusting shaft 723 is keyed to a first gear 722 that meshes with the first rack 721, and the other end of the adjusting shaft 723 away from the first gear 722 is keyed to a second gear 724.

Furthermore, when the reinforcing block 71 is engaged with the reinforcing groove, the stop block 81 will not abut against the connecting block 61. When the end of the reinforcing block 71 furthest from the cavity 611 is located inside the first sliding hole, the stop block 81 abuts against the connecting block 61. A conspicuous red mark is provided on the adjusting block 725 between the auxiliary block 82 and the connecting block 61.

[0052] Before the connecting block 61 engages with the connecting slot 121, the operator pulls the auxiliary block 82.

The red mark on the adjusting block 725 is located outside the connecting block 61. Then, the end of the connecting block 61 away from the positioning block 62 is engaged with the connecting groove 121, and the reinforcing block 71 enters into the connecting groove 121. Then, the auxiliary block 82 is released, and the reinforcing block 71 abuts against the side wall of the connecting groove 121.
