Description

Technical Field

[0001] The present invention relates to the technical field of powder mixing, and in particular to a mixing mechanism, a mixing device, and a mixing method. Background Art

[0002] A mixing mechanism is a machine that facilitates the mixing of various powders and is widely used in the powder, solid-liquid, and liquid mixing in industries such as pharmaceuticals, food, chemicals, oil fields, oil refining, and nuclear materials. A high-frequency vibration mixing mechanism generates high-frequency vibrations (usually 50 - 200 Hz) through a vibration motor or an electromagnetic drive system, and uses the vibration energy to cause intense collisions and diffusion between powder particles to quickly achieve uniform mixing.

[0003] However, different powders have different angle of repose. The angle of repose refers to the angle between the free surface of a powder accumulation body and the horizontal plane when the free surface is in the limit state of equilibrium in a gravitational field. The difference in the angle of repose of different powders will affect the mixing efficiency. For example, two powders with a large difference in the angle of repose may show a layering phenomenon during mixing. The powder with good fluidity (smaller angle of repose) may sink to the bottom, while the powder with poor fluidity (larger angle of repose) remains on the upper layer. Summary of the Invention

[0004] The purpose of the present invention is to improve the problem of poor mixing fluidity caused by the angle of repose of powders in the existing mixing mechanism, and to provide a mixing mechanism, a mixing device, and a mixing method.

[0012] The first end of the support block is mounted on the rotating shaft. The second end of the support block is sleeved outside the first adjustment rod. The first end of the first adjustment rod is slidably connected to the support block.

[0013] The second end of the moving block is sleeved outside the first adjustment rod, and the second end of the first adjustment rod is threadedly connected to the moving block.

[0014] In one embodiment, the regulator further has a second adjustment assembly. The second adjustment assembly includes a second adjustment rod, a first connection sleeve, and a second connection sleeve. The first end of the first connection sleeve is in rolling connection with the support plate. The first end of the second adjustment rod is movably connected to the second end of the first connection sleeve. The second end of the second adjustment rod is threadedly connected to the first end of the second connection sleeve.

[0015] In one embodiment, the regulator includes a first adjustment assembly and a second adjustment assembly. The driving assembly includes a driving member, a sliding shaft, a rotating shaft, and a joint member. The driving member is mounted on the support platform. The first end of the rotating shaft is mounted on the output end of the driving member. The second end of the rotating shaft is sleeved with the first end of the sliding shaft. In the second direction, the sliding shaft is slidably connected to the rotating shaft.

[0016] The second end of the sliding shaft is movably cooperated with the first end of the joint member. The first adjustment assembly is mounted on the rotating shaft and cooperates with the sliding shaft. The second end of the joint member is connected to the first end of the second adjustment assembly. The second end of the second adjustment assembly is in rolling connection with the support plate.

[0017] In one embodiment, the mixing mechanism further includes a guide rail, a sliding seat, a first pulley, and a second pulley. The guide rail is installed on the lower surface of the support plate and extends along the circumferential direction of the support plate.

[0018] The sliding seat is installed at the second end of the joint member. The first pulley and the second pulley are installed on the sliding seat. The guide rail is arranged between the first pulley and the second pulley and is slidably connected to the first pulley and the second pulley respectively.

[0019] A connecting rod is fixedly arranged under the sliding seat. The driving assembly has a sliding shaft and a joint member. The connecting rod is fixed to the first end of the joint member, and the sliding shaft is movably matched with the second end of the joint member.

[0020] In one embodiment, the limiting support member includes at least three springs. The three springs are distributed along the circumferential direction of the support plate. The two ends of the springs are respectively installed on the support plate and the support table, and the installation points of the springs are offset from the center of the support plate.

[0021] The present invention also provides a mixing device, which includes a vibrator and the above-mentioned mixing mechanism. The vibrator is installed on the support plate of the mixing mechanism and is arranged close to the center of the support plate.

[0022] In one embodiment, it further includes grinding balls and a container. The container is installed on the vibrator. A sealed mixing chamber is formed in the container, and the grinding balls are movably arranged in the mixing chamber.

[0023] The present invention also provides a mixing method for the mixing device, including the following steps:

[0024] Step 1: The support plate can move up and down on the limiting support member.

[0025] Step 2: The driving assembly abuts against the side of the support plate. In the first direction, the regulator adjusts the contact point to the first moving position. When the support plate is in a non-natural state, the output end of the driving assembly drives one side of the support plate to continuously move, and the contact point makes a continuous rotational movement.

[0026] In some embodiments, the regulator includes a first adjustment component and a second adjustment component. The mixing method further includes the following steps:

[0027] Use the first adjustment component to adjust the sliding shaft in the second direction and drive the contact point to move to the first moving position in the first direction.

[0028] Use the second adjustment component to adjust the sliding seat in the first direction and drive the contact point in the first direction. The contact point moves from the first moving position to the second moving position.

[0029] When the support plate is in its natural state supported by the limit support member, there is a first height difference between the height of the support plate and the first moving position, and a second height difference between the height of the support plate and the second moving position.

[0030] In some embodiments, by rotating the first adjusting rod, the first adjusting rod drives the moving block to drive the sliding shaft to move back and forth in the second direction, adjusting the position between the sliding shaft and the rotating shaft, and the contact point moves to the first moving position;

[0031] By rotating the second adjusting rod, the second adjusting rod drives the first connecting sleeve to move up and down in the first direction, and the contact point moves from the first moving position to the second moving position.

[0032] In some embodiments, the mixing method further includes: the grinding balls move up and down, radially, and at high speed in the container, and the grinding balls impact and roll the powder in the container.

[0033] The technical solution provided by the present invention has the following advantages and effects:

[0034] When the contact point is at the first moving position, the support plate is in an inclined state. When the support plate is inclined, the output end of the driving component acts on the side of the support plate and moves circumferentially around the support plate. The circumferential side of the support plate is continuously lifted, and the limit support member has a certain limiting effect on the side of the support plate, preventing the support plate from disengaging from the second end of the limit support member.

[0035] When the previous contact point moves to the next contact point, the acting force of the output end of the driving component on the previous contact point disappears, and the previous contact point on the support plate resets due to its own weight, and the previous contact point completes an up and down movement action; the output end of the driving component moves to the next contact point, and the next contact point will also complete the up and down movement action of the previous contact point. Therefore, under the continuous action of the driving component, the outer edge of the support plate jitters up and down continuously and regularly along the circumference of the support plate. During the jittering process, the outer edge on one side of the support plate is higher than the outer edge on the other side. The outer edge of the container follows the outer edge of the support plate to jitter, and the powder moves from the side of the container to the center of the container, realizing the radial movement of the powder in the container. The powder on the side of the container continuously moves to the center of the container, and the powder is mixed in the radial direction of the container.

[0036] The outer edge of this container jitters in an inclined manner, but the position of the container in the top view state does not shift, realizing the adjustment to adapt to the inclined angle of powder mixing, avoiding the phenomenon of powder accumulation during the mixing process in the container, changing the traditional mixing movement mode of the powder in the container, and significantly improving the mixing efficiency of the powder.

[0051] To facilitate the understanding of the present invention, the specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings of the specification.

[0053] Unless otherwise specified or defined, the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0054] It should be noted that when an element is considered to be "fixed to" another element, it can be directly fixed to the other element or there can be an intermediate element; when an element is considered to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time; when an element is considered to be "mounted on" another element, it can be directly mounted on the other element or there can be an intermediate element at the same time. When an element is considered to be "provided in" another element, it can be directly provided in the other element or there can be an intermediate element at the same time.

[0055] The present invention provides a mixing mechanism 100, as Figures 1 to 6As shown in the figure, it includes: a support plate 4, a limit support member 8, a support platform 7, and a drive assembly 6. The first end of the limit support member 8 is mounted on the support platform 7, the support plate 4 is mounted on the second end of the limit support member 8, and the support plate 4 is disposed above the support platform 7. The drive assembly 6 is mounted on the support platform 7, the output end of the drive assembly 6 is movably engaged with the support plate 4, there is a contact point 50 between the drive assembly 6 and the support plate 4, and the contact point 50 is disposed offset from the center of the support plate 4. The drive assembly 6 has a regulator 5, the regulator 5 acts on the position of the contact point 50 in a first direction, and the contact point 50 has at least a first moving position in the first direction. When the support plate 4 is in its natural state supported by the limit support member 8, there is a height difference between the height of the support plate 4 and the first moving position.

[0056] In this embodiment, a container 2 filled with powder is mounted on the support plate 4. The support plate 4 is movably mounted on the second end of the limit support member 8. The specific mounting method is not particularly limited here, but it is necessary to ensure that there is a space for the outer peripheral portion of the support plate 4 to move up and down on the limit support member 8. The drive assembly 6 is used to press against the side of the support plate 4, so that a contact point 50 is formed between the drive assembly 6 and the support plate 4. The force generated by the output end of the drive assembly 6 can continuously act on the side of the support plate 4. When the support plate 4 is in its natural state supported by the limit support member 8, it is horizontal or inclined. And the regulator 5 acts on the position of the contact point 50 in the first direction. When the contact point 50 moves to the first moving position in the first direction, when the support plate 4 is in its natural state supported by the limit support member 8, there is a height difference between the height of the support plate 4 and the first moving position. Since the support position of the output end of the drive assembly 6 is offset from the center of the support plate 4, the height of one side of the support plate 4 is significantly higher than that of the other side. Therefore, when the contact point 50 is at the first moving position, the support plate 4 is in an inclined state.

[0057] Further, when the support plate 4 is inclined, the output end of the driving assembly 6 acts on the side of the support plate 4 and moves circumferentially around the support plate 4. The circumferential side of the support plate 4 is continuously lifted, and the limiting support member 8 has a certain limiting effect on the side of the support plate 4 to prevent the support plate 4 from disengaging from the second end of the limiting support member 8. When the previous contact point 50 moves to the next contact point 50, the acting force of the output end of the driving assembly 6 on the previous contact point 50 disappears, and the previous contact point 50 on the support plate 4 resets due to its own weight, and the previous contact point 50 completes an up-and-down movement action; the output end of the driving assembly 6 moves to the next contact point 50, and the next contact point 50 will also complete the up-and-down movement action of the previous contact point 50. Therefore, under the continuous action of the driving assembly 6, the outer edge of the support plate 4 jitters up and down continuously and regularly along the circumference of the support plate 4. During the jittering process, the outer edge of one side of the support plate 4 is higher than the outer edge of the other side. The outer edge of the container 2 follows the jittering of the outer edge of the support plate 4, and the powder moves from the side of the container 2 to the center of the container 2, realizing the radial movement of the powder in the container 2. The powder on the side of the container 2 continuously moves to the center of the container 2, realizing the radial mixing of the powder in the container 2.

[0058] The outer edge of this container 2 jitters in an inclined manner, but the position of the container 2 in the top view state does not shift, realizing the adjustment to adapt to the inclined angle of powder mixing, avoiding the phenomenon of powder accumulation during the mixing process in the container 2, changing the traditional mixing and moving mode of the powder in the container 2, and significantly improving the mixing efficiency of the powder.

[0059] In some embodiments, the driving assembly 6 includes a driving member 61, a coupling 62, a rotating shaft 63, a sliding shaft 64, and a joint member 520. The driving member 61 is installed on the support platform 7. The first end of the rotating shaft 63 is installed at the output end of the driving member 61. The second end of the rotating shaft 63 and the sliding shaft 64 are sleeved with each other, and the length direction of the rotating shaft 63 intersects with the length direction of the sliding shaft 64. The regulator 5 has a first adjustment assembly 51. The first adjustment assembly 51 is installed on the rotating shaft 63 and cooperates with the first end of the sliding shaft 64. The second end of the sliding shaft 64 is movably cooperated with the first end of the joint member 520. The second end of the joint member 520 is in rolling connection with the support plate 4. In the second direction, the sliding shaft 64 is slidably connected with the rotating shaft 63.

[0060] Specifically, the driving member 61 is fixed on the support platform 7. The driving member 61 is used to drive the rotation of the rotating shaft 63. During the rotation of the rotating shaft 63, the sliding shaft 64 is driven to rotate, and then the joint member 520 is driven to rotate in sequence. The second end of the joint member 520 is in rolling connection with the support plate 4, so that the joint member 520 has a moving path of circumferential rotation around the support plate 4. When the contact point 50 between the joint member 520 and the side of the support plate 4 is at the first moving position, the joint member 520 continuously lifts the side of the support plate 4. Under the action of the limit support member 8, the side of the support plate 4 realizes self-repositioning, and further realizes that the outer edge of the support plate 4 jitters up and down continuously and regularly along the circumference of the support plate 4.

[0061] Furthermore, since the rotating shaft 63 and the sliding shaft 64 are sleeved with each other, and the sliding shaft 64 is slidably connected to the rotating shaft 63, the joint member 520 is movably matched with the sliding shaft 64. The first adjusting assembly 51 is matched with the first end of the sliding shaft 64. The first adjusting assembly 51 is used to adjust the positional relationship between the sliding shaft 64 and the rotating shaft 63, so as to realize the adjustment of the position of the sliding shaft 64 in the second direction. In this embodiment, the first direction intersects with the second direction. As Figures 7 to 9 shown, when the first adjusting assembly 51 adjusts the sliding shaft 64 to move back and forth in the second direction, a section of the joint member 520 supporting the support plate 4 is inclined, and the contact point 50 is at a lower position, and the side of the support plate 4 is inclined downward. When the first adjusting assembly 51 adjusts the sliding shaft 64 so that one end of the joint member 520 supporting the support plate 4 is in a vertical state, the contact point 50 is at a higher position, and the side of the support plate 4 is inclined upward. Therefore, in this embodiment, the first adjusting assembly 51 can also realize the adjustment of the position of the contact point 50 acting in the first direction by adjusting the moving position of the sliding shaft 64 in the second direction, so that the contact point 50 can also move to the first moving position, improving the flexibility of adjusting the position of the contact point 50 in the first direction.

[0062] Preferably, in order to further realize the adjustment of the position of the sliding shaft 64 in the second direction by the first adjusting assembly 51, as Figure 4 and Figure 5 shown, the first adjusting assembly 51 includes a first adjusting rod 511, a moving block 512, and a support block 513. The first end of the moving block 512 is sleeved outside the sliding shaft 64 and is rotatably connected to the sliding shaft 64; and in the second direction, the sliding shaft 64 abuts against the moving block 512; the first end of the support block 513 is installed on the rotating shaft 63, the second end of the support block 513 is sleeved outside the first adjusting rod 511, and the first end of the first adjusting rod 511 is slidably connected to the support block 513; the second end of the moving block 512 is sleeved outside the first adjusting rod 511, and the second end of the first adjusting rod 511 is threadedly connected to the moving block 512.

[0063] Specifically, by driving the first adjusting rod 511 to rotate, a threaded fit occurs between the first adjusting rod 511 and the moving block 512. Since the first adjusting rod 511 is slidably connected to the support block 513 and restricted by the support block 513, by rotating the first adjusting rod 511 forward or backward, the first adjusting rod 511 drives the moving block 512 to move back and forth in the second direction, and at the same time, the moving block 512 also drives the sliding shaft 64 to move back and forth in the second direction. When the driving of the first adjusting rod 511 to rotate stops, a threaded fit exists between the first adjusting rod 511 and the moving block 512, and the first adjusting rod 511 can also restrict the forward and backward movement of the sliding shaft 64 through the moving block 512, enabling the sliding shaft 64 to stably movably cooperate with the joint member 520, realizing the adjustment of the position of the sliding shaft 64 in the second direction by the first adjusting assembly 51.

[0064] Preferably, the driving assembly 6 further has a third linear bearing 65. The third linear bearing 65 is fixed on the rotating shaft 63 and sleeved outside the sliding shaft 64. The sliding shaft 64 is slidably connected to the rotating shaft 63 through the third linear bearing 65. Specifically, the third linear bearing 65 is used to reduce the frictional force between the sliding shaft 64 and the rotating shaft 63 and improve the freedom degree of the sliding shaft 64 in the second direction. By providing the third linear bearing 65, the first adjusting rod 511 will be smoother when adjusting the movement of the sliding shaft 64, improving the practicability of the first adjusting assembly 51.

[0065] In some embodiments, the regulator 5 further has a second adjusting assembly 52. The second adjusting assembly 52 includes a second adjusting rod 523, a first connecting sleeve 521, and a second connecting sleeve 522. The first end of the first connecting sleeve 521 is in rolling connection with the support plate 4. The first end of the second adjusting rod 523 is movably connected to the second end of the first connecting sleeve 521. The second end of the second adjusting rod 523 is in threaded connection with the first end of the second connecting sleeve 522. The second end of the second connecting sleeve 522 is installed on the output end of the driving assembly 6.

[0066] Specifically, the second adjusting rod 523 is movably connected to the first connecting sleeve 521 to prevent the first connecting sleeve 521 from rotating when the second adjusting rod 523 is rotated, ensuring the stability of the contact point 50 between the first connecting sleeve 521 and the support plate 4; by rotating the second adjusting rod 523 clockwise, a threaded fit occurs between the second adjusting rod 523 and the second connecting sleeve 522, thereby adjusting the distance between the second adjusting rod 523 and the second connecting sleeve 522, and thus adjusting the length of the second adjusting assembly 52 in the first direction, realizing the direct action on the position of the contact point 50 in the first direction through the second adjusting assembly 52. In this embodiment, the first connecting sleeve 521 and the second connecting sleeve 522 can be interchanged in position, and no special limitation is made here.

[0067] In some embodiments, the regulator 5 includes a first adjustment component 51 and a second adjustment component 52. The drive component 6 includes a drive member 61, a sliding shaft 64, a rotating shaft 63, and a joint member 520. The drive member 61 is mounted on the support platform 7. The first end of the rotating shaft 63 is mounted on the output end of the drive member 61. The second end of the rotating shaft 63 and the first end of the sliding shaft 64 are sleeved with each other. In the second direction, the sliding shaft 64 is slidably connected to the rotating shaft 63. The second end of the sliding shaft 64 is movably engaged with the first end of the joint member 520. The first adjustment component 51 is mounted on the rotating shaft 63 and cooperates with the sliding shaft 64. The second end of the joint member 520 is connected to the first end of the second adjustment component 52. The second end of the second adjustment component 52 is in rolling connection with the support plate 4.

[0068] Specifically, in this embodiment, the first adjustment component 51 and the second adjustment component 52 are used together to adjust the position of the contact point 50 in the first direction. As Figures 6 to 9 shown, the first adjustment component 51 adjusts the position of the sliding shaft 64 in the second direction, which can indirectly adjust the position of the contact point 50 in the first direction. After the first adjustment component 51 adjusts the contact point 50 to the highest point it can adjust, an angle 53 is formed between the support plate 4 and the horizontal line 55. The second adjustment component 52 is used to continue adjusting the contact point 50, so that the contact point 50 is further adjusted, the side part of the support plate 4 is further lifted, and the angle 53 between the support plate 4 and the horizontal line 55 becomes larger, increasing the inclination angle of the support plate 4. Therefore, by using the first adjustment component 51 and the second adjustment component 52 in cooperation, the limitation of the angular movement range of the joint member 520 is avoided. Under the action of the first adjustment component 51 and the second adjustment component 52, the adjustment range of the joint member 520 with the same angle is maximally increased.

[0069] In this embodiment, the specific structures of the first adjustment component 51 and the second adjustment component 52 can refer to other embodiments of this specification, and will not be elaborated here one by one.

[0070] In addition, assuming that the adjustment angle of the joint member 520 is ±20°, the characteristics of different powder materials are different. The inclination angle is determined according to the angle of repose of the powder. The angle of repose of conventional powder is between 20° and 45°. By cooperating the first adjustment component 51 and the second adjustment component 52, the adjustment range 54 of the contact point 50 can be increased, so that the maximum angle of the mixing mechanism 100 can be adjusted to 40°, which can meet the mixing of more than 85% of the conventional powder materials.

[0071] In some embodiments, the mixing mechanism 100 further includes a guide rail 41, a sliding seat 42, a first pulley 43, and a second pulley 44. The guide rail 41 is installed on the lower surface of the support plate 4 and extends along the circumferential direction of the support plate 4. The sliding seat 42 is installed at the second end of the joint member 520. The first pulley 43 and the second pulley 44 are installed on the sliding seat 42. The guide rail 41 is disposed between the first pulley 43 and the second pulley 44 and is in rolling connection with the first pulley 43 and the second pulley 44 respectively. A connecting rod is fixedly disposed under the sliding seat 42. The driving assembly 6 has a sliding shaft 64 and a joint member 520. The connecting rod is fixed to the first end of the joint member 520, and the sliding shaft 64 is movably engaged with the second end of the joint member 520.

[0072] Specifically, in this embodiment, this connecting rod can be the second adjustment assembly 52. The connecting rod is fixed to the lower end of the sliding seat 42, so that the connecting rod and the sliding seat 42 form an integral structure. The connecting rod is also fixed to the joint member 520. Therefore, in the first direction, the joint member 520 is fixed to the sliding seat 42 and drives the sliding seat 42 to move. When the sliding seat 42 moves, the first pulley 43 and the second pulley 44 on the sliding seat 42 are in rolling engagement with the inner and outer sides of the guide rail 41, reducing the friction between the sliding seat 42 and the guide rail 41, reducing the power consumption of the driving assembly 6 acting on the side of the support plate 4, and further realizing the movable engagement between the output end of the driving assembly 6 and the outer edge of the support plate 4.

[0073] In some embodiments, other methods can also be used to achieve the movable engagement between the sliding seat 42 and the support plate 4. For example, magnetic levitation propulsion. The working principle of magnetic levitation propulsion is mainly based on electromagnetic force and the interaction of magnetic poles. Specifically, magnetic levitation technology uses the force generated by an electromagnetic field. By controlling the direction and intensity of the magnetic field, the magnetic fields between the object and the track are like poles facing each other, thereby generating a repulsive force to lift the object and keep it at a certain height, thus realizing the movable engagement between the output end of the driving member 61 and the outer edge of the support plate 4.

[0074] In some embodiments, the limiting support member 8 includes six springs 81. The six springs 81 are distributed along the circumferential direction of the support plate 4. The two ends of the spring 81 are respectively installed on the support plate 4 and the support platform 7, and the installation points of the spring 81 deviate from the center of the support plate 4.

[0075] Specifically, the upper end of the spring 81 exerts a restraining force on the side of the support plate 4, and the six springs 81 are arranged circumferentially around the support plate 4. Therefore, there are restraining forces at different positions in the circumferential direction of the support plate 4, which are used to limit the moving distance of the support plate 4. When the support plate 4 is lifted by the output end of the driving assembly 6, the spring 81 will generate a corresponding reaction force. When the previous contact point 50 moves to the next contact point 50, the spring 81 will act on the previous contact point 50 to reset the side of the support plate 4 located at the previous contact point 50. When the support plate 4 moves to the next contact point 50, it will also cause the spring 81 to generate a corresponding reaction force. When the output end of the driving assembly 6 continuously acts on the circumference of the support plate 4 and is in active cooperation with the circumference of the support plate 4, the outer edge of the support plate 4 will vibrate up and down continuously and regularly along the circumference of the support plate 4. In this embodiment, the limiting support member 8 is not limited to the spring 81.

[0076] In addition, the outer edge of the support plate 4 is fixed by the spring 81, and the spring 81 is pulled or squeezed to generate a reaction force. When the joint member 520 continuously rolls on the circumference of the support plate 4, the outer edge of the support plate 4 is shaken by the springs 81 at different positions. If the rotation speed of the sliding seat 42 is relatively fast, the outer edge of the support plate 4 will continuously shake in the circumferential direction of the support plate 4, further increasing the vibration frequency of the container 2 on the support plate 4.

[0077] In another embodiment, the limiting support member 8 includes a plurality of support rods and a plurality of first linear bearings (not shown in the drawings). The plurality of support rods are arranged around the support plate 4. The first end of each support rod is installed on the support platform 7, and each of the first linear bearings is sleeved on the second end of the support rod; in the first direction, the support plate 4 is slidably connected to the support rod through the first linear bearing, and the second end of the support rod has a limiting portion that abuts against the top of the support plate 4. Specifically, the friction between the support plate 4 and the support rod during the active cooperation is reduced by the first linear bearing. When the side of the support plate 4 is lifted by the output end of the driving assembly 6 and the previous contact point 50 moves to the next contact point 50, the side of the support plate 4 can be reset automatically, and the outer edge of the support plate 4 can also vibrate up and down continuously and regularly along the circumference of the support plate 4.

[0078] In some embodiments, the joint member 520 includes a first connection head 524 and a second connection head 525. The first connection head 524 has an activity groove, at least part of the second connection head 525 is disposed in the activity groove, and the outer wall of the second connection head 525 is rotatably connected to the inner wall of the activity groove. Specifically, the second connection head 525 moves in the activity groove of the first connection head 524 to achieve the active cooperation between the first connection head 524 and the second connection head 525. In addition, the joint member 520 can also be a universal joint structure, etc., which is not specifically limited herein.

[0079] The present invention also provides a mixing device, which includes a vibrator 3 and the mixing mechanism 100 as described above. The vibrator 3 is installed on the support plate 4 of the mixing mechanism 100 and is disposed near the center of the support plate 4. Specifically, the container 2 filled with powder is installed on the vibrator 3, and the vibrator 3 is arranged on the support plate 4. The vibrator 3 drives the powder in the container 2 to be mixed in a way of moving up and down. The driving component 6 abuts against the side of the support plate 4. Under the action of the limit support member 8, the powder on the side of the container 2 on the support plate 4 continuously moves towards the center of the container 2, realizing the movement of the powder in the radial direction and the axial line direction of the container 2. Through two completely different mixing methods, the mixing efficiency of the powder is greatly improved.

[0080] Preferably, as Figure 1 and Figure 10 shown, the vibrator 3 includes a magnetic cylinder 31, a moving plate 34, a second linear bearing 32, a guide rod 33, and a coil (not shown in the figure). The magnetic cylinder 31 and the second linear bearing 32 are both installed on the support plate 4. The moving plate 34 is installed at the upper end of the guide rod 33. The second linear bearing 32 is sleeved outside the guide rod 33. The guide rod 33 is slidably connected to the second linear bearing 32. The coil is installed at the lower end of the moving plate 34 and is located above the magnetic cylinder 31. The container 2 is fixed at the upper end of the moving plate 34. After the magnetic cylinder 31 is electrified, it drives the coil to move. By changing the direction of the current, the coil moves up and down, and the coil drives the moving plate 34 and the container 2 to vibrate up and down at a high frequency. The second linear bearing 32 restricts the moving direction of the guide rod 33, improves the stability of the up and down vibration of the container 2, and at the same time reduces the friction force of the up and down movement of the guide rod 33, reducing the power consumption required for the moving plate 34 to drive the container 2 to vibrate.

[0081] In some other embodiments, the vibrator 3 can also adopt a piezoelectric vibrator, an electric vibrator, or a pneumatic vibrator, which is not specifically limited herein.

[0082] Preferably, as Figure 10 shown, the mixing mechanism 100 further has a pressing mechanism 1. The pressing mechanism 1 includes a support frame 11 and a pressing member 12. The pressing member 12 includes a push rod 122 and a sealing plug 121. The support frame 11 is installed on the moving plate 34. The sealing plug 121 is installed at the lower end of the push rod 122. The push rod 122 is threadedly connected to the support frame 11. By rotating the push rod 122, the push rod 122 drives the sealing plug 121 to seal the opening of the container 2, preventing the powder from splashing and falling from the opening of the container 2 when the container 2 vibrates under the action of the vibrator 3.

[0083] In some embodiments, the mixing device further includes grinding balls and a container 2. The container 2 is mounted on a vibrator 3. A sealed mixing chamber is formed inside the container 2, and the grinding balls are movably arranged inside the mixing chamber. Specifically, the grinder is placed inside the container 2. Under the action of the vibrator 3 and the driving assembly 6, the grinder impacts the powder inside the sealed mixing chamber to achieve grinding of the powder.

[0084] In addition, the grinding balls move along the axial line and in the radial direction of the container 2. Therefore, the mixing and grinding efficiency of this mixing device is higher, 3-5 times that of traditional mechanical stirring; there is no mixing structure such as a paddle during the mixing and ball milling processes, avoiding the adhesion of the powder, which can not only ensure the purity of the powder but also avoid waste of the powder; due to the absence of a traditional stirrer, the energy consumption of the mixing device during operation is lower, reducing the energy consumption by about 30%; traditional mixing devices can only be used for one purpose, while this device can be used for two purposes, that is, it can be used for mixing and also for grinding, achieving dual use.

[0085] The present invention also proposes a mixing method for a mixing device, including the following steps:

[0086] Step 1: Mount the container 2 filled with powder on the vibrator 3;

[0087] Step 2: Start the vibrator 3. The vibrator 3 drives the container 2 to move up and down, and the powder inside the container 2 moves up and down for mixing;

[0088] Step 3: The support plate 4 can move up and down on the limit support 8;

[0089] The driving assembly 6 abuts against the side of the support plate 4. In the first direction, the regulator 5 adjusts the contact point 50 to the first moving position. In a non-natural state of the support plate 4, the output end of the driving assembly 6 drives one side of the support plate 4 to continuously move, and the contact point 50 makes a continuous rotational movement.

[0090] Through the above mixing method, the powder can be mixed up and down inside the container 2. By the action of the regulator 5 on the position of the contact point 50 in the first direction, the contact point 50 is at the first moving position. In a non-natural state of the support plate 4, an angle 53 is formed between the support plate 4 and the horizontal plane. The joint 520 is in sliding fit with the outer edge of the support plate 4, realizing the mixing of the powder from the side of the container 2 towards the center of the container 2. Using two completely different mixing methods to achieve high-frequency mixing of the powder and improve the mixing efficiency of the powder.

[0091] Preferably, the mixing method further includes the following steps:

[0092] Use the first adjustment assembly 51 to adjust the sliding shaft 64 in the second direction and drive the contact point 50 to move to the first moving position in the first direction;

[0093] The second adjusting component 52 is used to adjust the sliding seat 42 in the first direction, and drive the contact point 50 in the first direction, and the contact point 50 moves from the first moving position to the second moving position;

[0094] In the natural state when the support plate 4 is supported by the limit support member 8, there is a first height difference between the height of the support plate 4 and the first moving position, and a second height difference between the height of the support plate 4 and the second moving position.

[0095] Specifically, the first adjusting component 51 is used to adjust the sliding shaft 64 in the second direction. During the movement of the sliding shaft 64, the contact point 50 moves in the first direction, indirectly adjusting the position of the contact point 50 in the first direction, so that the contact point 50 moves to the first moving position; the second adjusting component 52 is used to continue to adjust the sliding seat 42 in the first direction, further adjusting the position of the contact point 50 in the first direction, so that the contact point 50 moves from the first moving position to the second moving position. Through secondary adjustment of the contact point 50, the moving range of the contact point 50 in the first direction is further increased, so that the contact point 50 has different height positions. Moreover, the first adjustment method is indirect adjustment, and the second adjustment method is active adjustment. By using two completely different adjustment methods, the flexibility of adjustment is increased.

[0096] Preferably, rotate the first adjusting rod 511, and the first adjusting rod 511 drives the moving block 512 to drive the sliding shaft 64 to move back and forth in the second direction, adjusting the position between the sliding shaft 64 and the rotating shaft 63, and the contact point 50 moves to the first moving position; rotate the second adjusting rod 523, and the second adjusting rod 523 drives the first connecting sleeve 521 to move up and down in the first direction, and the contact point 50 moves from the first moving position to the second moving position. Specifically, by rotating the first adjusting rod 511 clockwise or counterclockwise, the first adjusting rod 511 drives the sliding shaft 64 to move back and forth in the second direction through the moving block 512, thereby adjusting the up and down movement of the contact point 50 to satisfy that the contact point 50 has the first moving position. By rotating the second adjusting rod 523 clockwise or counterclockwise, the second adjusting rod 523 drives the first connecting sleeve 521 to move up and down, driving the sliding seat 42 to move up and down in the first direction, thereby adjusting the up and down movement of the contact point 50 to satisfy that the contact point 50 has the second moving position.

[0097] Preferably, the mixing method further includes that the grinding balls move up and down, radially and at high speed in the container 2, and the grinding balls impact and roll the powder in the container 2. Specifically, if the grinding balls are placed in the container 2 and the grinding balls move with the container 2, the grinding balls can play a grinding effect in the container 2. Therefore, this mixing method can simultaneously have the functions of mixing and grinding, further realizing the dual use of one machine.
