Description

Technical Field

[0001] This invention relates to the field of paste filling material manufacturing technology, and more specifically, to a device and method for uniformly dispersing hollow microspheres in a lightweight energy-absorbing paste filling material. Background Technology

[0002] In lightweight energy-absorbing paste filling materials, hollow microspheres are often used as core functional fillers. With their lightweight, hollow structure and excellent mechanical and physical properties, they can reduce the density of paste materials and significantly improve their energy absorption and buffering effect. They are widely applicable to scenarios such as mine filling and engineering protection that require lightweight materials and impact resistance.

[0003] Dispersion equipment is crucial for ensuring the uniform dispersion of hollow microspheres in pastes and preventing agglomeration. Dispersion equipment uses internal stirring rods to agitate the materials, achieving dispersion. However, some existing dispersion equipment uses only ordinary one-way stirring, causing the materials to move in the same direction as the stirring shaft, resulting in insufficient cross-mixing. Most importantly, the stirring rods on the stirring shaft are often integrated structures, directly welded to the shaft. This traditional rigid stirring rod has a fixed stirring range, easily creating dead zones and failing to agitate the materials, thus failing to achieve uniform dispersion. Therefore, we provide a device and method for uniformly dispersing lightweight energy-absorbing paste filling materials containing hollow microspheres. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for uniformly dispersing lightweight energy-absorbing paste-like filling materials with hollow microspheres, in order to solve the problems mentioned in the background art above:

[0005] Currently, some existing dispersion equipment uses a simple one-way stirring method for its stirring rods. The materials tend to move in the same direction as the stirring shaft, resulting in insufficient cross-mixing. Most importantly, the stirring rods on the stirring shaft are mostly one-piece structures, directly welded to the stirring shaft. The stirring range of this traditional rigid stirring rod is relatively fixed, which easily creates stirring dead zones and makes it impossible to turn the materials over, thus failing to achieve the purpose of uniform dispersion.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A device for uniformly dispersing lightweight energy-absorbing paste-like filling material hollow microspheres includes a material tank. A stirring shaft is rotatably connected inside the material tank. A first stirring rod is fixedly connected to the outside of the stirring shaft. A second stirring rod is rotatably connected to the end of the first stirring rod away from the stirring shaft. A third stirring rod is rotatably connected to the end of the second stirring rod away from the first stirring rod. A rotating frame is rotatably connected to the outside of the first stirring rod. A first connecting rod is provided between the rotating frame and the second stirring rod. One end of the first connecting rod is rotatably connected to the rotating frame, and the other end of the first connecting rod is rotatably connected to the second stirring rod. A second connecting rod is provided between the first and third stirring rods. One end of the second connecting rod is rotatably connected to the first stirring rod, and the other end of the second connecting rod is rotatably connected to the third stirring rod. When the rotating frame swings back and forth, it drives the second and third stirring rods to rotate through the first connecting rod. The third stirring rod rotates further under the action of the second connecting rod, causing the second and third stirring rods to change from a straight state to a bent state. The stirring shaft has a hollow structure, and a first transmission mechanism is set inside the stirring shaft. Under the action of the first transmission mechanism, the second and third stirring rods can automatically bend, thereby improving the stirring effect on the material. A second transmission mechanism is set on the top of the material bucket, which drives the stirring shaft to rotate as a whole.

[0008] In a preferred embodiment of the present invention, the first transmission mechanism includes a fixed rod, which is vertically placed inside the stirring shaft. The bottom end of the fixed rod is fixedly connected to the material bucket, and the top end of the fixed rod is fixedly connected to a fixed frame, which is also fixedly connected to the material bucket. An installation groove is provided inside the first stirring rod, and a rotating rod is rotatably connected inside the installation groove. The rotating rod vertically penetrates the first stirring rod and extends to the outside of the first stirring rod. The rotating frame is fixedly connected to the rotating rod. A first gear is sleeved on the outside of the rotating rod and is fixedly connected to the rotating rod. A rack is slidably connected inside the installation groove, and the first gear meshes with the rack. The rack penetrates the stirring shaft and extends to the inside of the stirring shaft. The rack is slidably connected to the stirring shaft. When the rack moves back and forth, it can drive the rotating rod to rotate back and forth in both directions through the first gear.

[0009] In a preferred embodiment of the present invention, the outer wall of the rack is fitted with the inner wall of the mounting groove, and the rack is fitted together with the mounting groove, thereby limiting the rack by the mounting groove itself.

[0010] In a preferred embodiment of the present invention, a movable block is fixedly connected to one end of the rack near the fixed rod. A first sliding groove is vertically formed inside the movable block. A first sliding rod is slidably connected inside the first sliding groove. First circular plates are fixedly connected to both ends of the first sliding rod. A rotating shaft is fixedly connected to the side of the first circular plate away from the first sliding rod. A support frame is rotatably connected to the other end of the rotating shaft. The support frame is sleeved on the outside of the fixed rod and rotatably connected to the fixed rod. A second gear is sleeved outside the rotating shaft and between the support frame and the first circular plate. The second gear... The rotating shaft is fixedly connected, and a third gear is sleeved on the outside of the fixed rod. The third gear is fixedly connected to the fixed rod, and the second gear meshes with the third gear. A support rod is fixedly connected between the upper and lower support frames. The support rod is fixedly connected to the inner wall of the stirring shaft. The support rod has a U-shaped structure, and there are three support rods symmetrically distributed. The rotating shaft is located between two adjacent support rods. When the stirring shaft rotates, it will drive the support frame to rotate around the fixed rod through the support rod. Under the action of the second gear and the third gear, the rotating shaft on the support frame will drive the first circular plate to rotate.

[0011] In a preferred embodiment of the present invention, the second transmission mechanism includes a mounting plate fixedly connected to a material barrel. A second circular plate is rotatably connected to the bottom of the mounting plate. A swing plate is rotatably connected to the top of the material barrel and below the second circular plate. A second sliding groove is provided inside the swing plate. A second sliding rod is slidably connected inside the second sliding groove. The second sliding rod is fixedly connected to the second circular plate. An external gear ring is fixedly connected to the outer end of the swing plate near the stirring shaft. The top of the stirring shaft extends upward beyond the top of the material barrel. A fourth gear is sleeved on the top of the stirring shaft. The fourth gear is fixedly connected to the stirring shaft and meshes with the external gear ring. The center of the external gear ring is the same as the center of the swing plate when it swings back and forth. When the swing plate swings back and forth, the external gear ring rotates back and forth in opposite directions.

[0012] As a preferred embodiment of the present invention, the second slide groove is an arc-shaped structure. When the swing plate swings back and forth, the center of the arc-shaped second slide groove can coincide with the center of the second circular plate. When the center of the second slide groove coincides with the center of the second circular plate, the second slide rod on the second circular plate will not squeeze the inner wall of the second slide groove. At this time, the second circular plate continues to rotate, and the swing plate will not swing.

[0013] In a preferred embodiment of the present invention, a motor is fixedly connected to the top of the mounting plate, the output shaft of the motor vertically penetrates the mounting plate and extends to the bottom of the mounting plate, the output shaft of the motor is rotatably connected to the mounting plate, the second circular plate is fixedly connected to the output end of the motor, a control panel is fixedly connected to the outside of the material bucket, the motor is electrically connected to the control panel, the electrical equipment is powered by an external power supply and controlled by the control panel, when the user starts the motor through the control panel, the motor will directly drive the second circular plate to rotate, the second circular plate will squeeze the inner wall of the second slide groove through the second slide rod to drive the swing plate to swing back and forth, and the swing plate will drive the stirring shaft to rotate through the external gear ring and the fourth gear.

[0014] A method for using a device for uniformly dispersing lightweight energy-absorbing paste-like filling material hollow microspheres, the method comprising the following specific steps:

[0015] Step 1: In lightweight energy-absorbing paste filling materials, hollow microspheres are often used as core functional fillers. Due to their lightweight, hollow structure and excellent mechanical and physical properties, they can reduce the density of the paste material and significantly improve its energy absorption and buffering effect. They are widely applicable to scenarios such as mine filling and engineering protection where lightweight materials and impact resistance are required. Dispersion equipment is crucial to ensure the uniform dispersion of hollow microspheres in the paste and prevent agglomeration. During use, the motor is started via the control panel, which drives the second circular plate to rotate. The plate drives the second sliding rod to perform a circular motion. During this process, the second sliding rod will squeeze the inner wall of the second chute, thereby causing the swing plate to swing back and forth. The swing plate drives the outer gear ring to rotate back and forth in both directions. The outer gear ring drives the stirring shaft to rotate back and forth in both directions through the fourth gear. Finally, the stirring shaft drives the first stirring rod, the second stirring rod, and the third stirring rod to stir the hollow microspheres in the material barrel to achieve the purpose of dispersion. Since the second chute has an arc-shaped structure, when the swing plate swings to the point where the center of the second chute coincides with the center of the second circular plate... When the mixing is complete, the second slide bar will not press against the inner wall of the second chute, and the swing plate will remain stationary. Correspondingly, the stirring shaft will also remain stationary, allowing the stirring shaft to perform a mixing method that rotates from forward to backward, pauses, and then reverses. This mixing method can improve the uniformity of mixing and prevent clumping. In ordinary unidirectional mixing, the material tends to follow the stirring shaft in a circular motion in the same direction, forming a relatively stable material flow. This can lead to insufficient cross-mixing of the material. Reversing the mixing can break this fixed flow direction, forcing the material to collide and interweave with each other. The pause allows the moving material to be briefly buffered, preventing it from continuing to move in the same direction due to inertia, thus creating better conditions for mixing during reversal. At the same time, the bottom and edges of the material tank are difficult to reach with the force of the stirring shaft in traditional unidirectional mixing, easily forming dead corners. This causes the material in these areas to remain unmixed for a long time. During reversal, the direction of force on the stirring shaft changes, which can move the material that was originally in the dead corners towards the center. Combined with the pause, the material in the dead corners can be further loosened and brought into the mixing system by the subsequent mixing action.

[0016] Step Two: During the rotation of the stirring shaft, the stirring shaft drives the support frame to rotate via the support rod, causing the rotating shaft on the support frame to revolve around the fixed rod. Simultaneously, the rotating shaft also rotates on its own axis under the action of the second and third gears, causing the rotating shaft to drive the first circular plate to rotate. The first circular plate then drives the first sliding rod to perform circular motion. The first sliding rod, by pressing against the inner wall of the first sliding groove, causes the movable block to move back and forth radially around the stirring shaft. The movable block then drives the rack to move back and forth, and the rack, via the first gear, drives the rotating rod to rotate in both directions. Finally, the rotating rod causes the rotating frame to swing back and forth. When the rotating frame swings back and forth, it drives the second and third stirring rods to rotate via the first connecting rod. During the rotation of the second and third stirring rods, the third stirring rod will further rotate under the action of the second connecting rod, causing the second and third stirring rods to change from a straight state to a bent state, and then return to their original positions. In a straight-line configuration, based on rotary stirring, the downward bending of the second and third stirring rods achieves dynamic, multi-angle material tumbling, significantly improving stirring efficiency and uniformity. Traditional rigid stirring shafts have a fixed stirring range, easily creating dead zones at the bottom and side walls of the container. The flexible structure of the second and third stirring rods, however, automatically bends and straightens during rotation, allowing them to get closer to the bottom and side walls of the container, covering more space and resulting in more uniform material mixing. Furthermore, when bending, the second and third stirring rods create scraping and pushing actions at different angles, resulting in stronger shearing force on the material. The downward bending motion flips the material at the bottom of the container upwards while pressing the upper layer downwards, creating vertical convection and preventing material stratification. The material is divided into two groups, one rotating upwards and the other downwards, further enhancing the tumbling effect and mixing uniformity.

[0017] Compared with the prior art, the present invention has the following technical effects:

[0018] 1. In use, the lightweight energy-absorbing paste filling material hollow microsphere uniform dispersion equipment uses a motor to drive the second circular plate to rotate. The second slide rod squeezes the inner wall of the second slide groove, causing the swing plate to swing back and forth. The swing plate drives the stirring shaft to rotate back and forth in both directions through the external gear ring and the fourth gear. Finally, the stirring shaft drives the first, second, and third stirring rods to stir the hollow microspheres in the material barrel to achieve dispersion. Since the second slide groove is an arc-shaped structure, when the swing plate swings to the point where the center of the second slide groove coincides with the center of the second circular plate, the stirring shaft remains stationary. This allows the stirring shaft to have a stirring mode from forward rotation to pause and then to reverse rotation, which can improve the uniformity of mixing. It forces the materials to collide and interweave with each other. The pause allows the moving materials to be briefly buffered, avoiding continuous unidirectional movement due to inertia, creating better conditions for mixing during reverse rotation. At the same time, during reverse rotation, the force direction of the stirring shaft changes, which can move the materials that were originally in dead corners towards the center. Combined with the pause, it can further loosen the materials in dead corners, so that they can be brought into the mixing system by the subsequent stirring action.

[0019] 2. In use, the lightweight energy-absorbing paste filling material hollow microsphere uniform dispersion equipment operates as follows: During the rotation of the stirring shaft, the shaft revolves around the fixed rod. Under the action of the second and third gears, the rotating shaft rotates on its own axis, driving the first circular plate to rotate. The first sliding rod, by pressing against the inner wall of the first sliding groove, drives the movable block and rack to move back and forth. The rack, through the first gear and the rotating rod, drives the rotating frame to swing back and forth. The rotating frame, through the first connecting rod, drives the second and third stirring rods to rotate. The third stirring rod, under the action of the second connecting rod, further rotates, causing the second and third stirring rods to change from a straight state to a bent state, and then back to a straight state. In this system, based on rotary stirring, the downward bending of the second and third stirring rods achieves dynamic, multi-angle material tumbling. Simultaneously, the bendable structure of the second and third stirring rods allows them to fit closer to the bottom and side walls of the container during rotation, covering more space and resulting in more uniform material mixing. Furthermore, the bending of the second and third stirring rods creates scraping and pushing actions at different angles, resulting in stronger shearing force on the material. The downward bending motion flips the material at the bottom of the container upwards while pressing the upper layer downwards, creating convection currents that prevent material stratification and improve the tumbling effect and mixing uniformity.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figures 1 to 8A device for uniformly dispersing hollow microspheres in a lightweight energy-absorbing paste filling material includes a material tank 1. A stirring shaft 2 is rotatably connected inside the material tank 1. Six first stirring rods 3 are fixedly connected to the outside of the stirring shaft 2. These first stirring rods 3 are arranged symmetrically in groups of three, one group at the top and one group at the bottom. The second stirring rod 4 and the third stirring rod 5 on the upper first stirring rod 3 rotate upwards, while the second stirring rod 4 and the third stirring rod 5 on the lower first stirring rod 3 rotate downwards. A second stirring rod 4 is rotatably connected to the end of the first stirring rod 3 furthest from the stirring shaft 2, and a third stirring rod 5 is rotatably connected to the end of the second stirring rod 4 furthest from the first stirring rod 3. The outer side of the first stirring rod 3 rotates... A rotating frame 6 is movably connected, and a first connecting rod 7 is provided between the rotating frame 6 and the second stirring rod 4. One end of the first connecting rod 7 is rotatably connected to the rotating frame 6, and the other end of the first connecting rod 7 is rotatably connected to the second stirring rod 4. A second connecting rod 8 is provided between the first stirring rod 3 and the third stirring rod 5. One end of the second connecting rod 8 is rotatably connected to the first stirring rod 3, and the other end of the second connecting rod 8 is rotatably connected to the third stirring rod 5. When the rotating frame 6 swings back and forth, it will drive the second stirring rod 4 and the third stirring rod 5 to rotate through the first connecting rod 7. The third stirring rod 5 will rotate further under the action of the second connecting rod 8, so that the second stirring rod 4 and the third stirring rod 5 change from a straight state to a bent state. The stirring shaft 2 has a hollow structure and a first transmission mechanism 9 is installed inside it. Under the action of the first transmission mechanism 9, the second stirring rod 4 and the third stirring rod 5 can bend automatically, thereby improving the stirring effect on the material. The top of the material bucket 1 is equipped with a second transmission mechanism 10, which drives the stirring shaft 2 to rotate as a whole. The stirring shaft 2 drives the first stirring rod 3, the second stirring rod 4 and the third stirring rod 5 to stir the material and achieve the dispersion of the material.

[0031] Furthermore, the first transmission mechanism 9 includes a fixed rod 11, which is vertically placed inside the stirring shaft 2. The bottom end of the fixed rod 11 is fixedly connected to the bottom of the material bucket 1, and the top end of the fixed rod 11 is fixedly connected to a fixed frame 12, which is fixedly connected to the top of the material bucket 1. The first stirring rod 3 has an installation groove 13 inside, and a rotating rod 14 is rotatably connected inside the installation groove 13. The rotating rod 14 vertically penetrates the first stirring rod 3 and extends to the outside of the first stirring rod 3. The rotating frame 6 is fixedly connected to the rotating rod 14. A first gear 15 is sleeved on the outside of the rotating rod 14 and is fixedly connected to the rotating rod 14. A rack 16 is slidably connected inside the installation groove 13. The first gear 15 and the rack 16 are meshed. The rack 16 penetrates the stirring shaft 2 and extends to the inside of the stirring shaft 2. The rack 16 is slidably connected to the stirring shaft 2. When the rack 16 moves back and forth, it can drive the rotating rod 14 to rotate back and forth in the forward and reverse directions through the first gear 15. The rotating rod 14 then drives the rotating frame 6 to swing back and forth.

[0032] Furthermore, the outer sidewall of the rack 16 fits against the inner sidewall of the mounting groove 13, and the rack 16 fits against the mounting groove 13. The mounting groove 13 itself limits the rack 16, so that the rack 16 can always maintain normal meshing with the first gear 15.

[0033] Furthermore, a movable block 17 is fixedly connected to one end of the rack 16 near the fixed rod 11. A first groove 18 is vertically formed inside the movable block 17, and this first groove 18 is strip-shaped in the horizontal direction. A first slide rod 19 is slidably connected inside the first groove 18. A first circular plate 20 is fixedly connected to both the upper and lower ends of the first slide rod 19. A rotating shaft 21 is fixedly connected to the side of the first circular plate 20 away from the first slide rod 19. The axis of the rotating shaft 21 is parallel to the axis of the first circular plate 20. One end of the rotating shaft 21 is fixedly connected to the side of the first circular plate 20 away from the first slide rod 19, and the other end of the rotating shaft 21 is rotatably connected to a support frame 22. The support frame 22 is sleeved on the outside of the fixed rod 11 and rotatably connected to the fixed rod 11. A second gear 23 is sleeved between the support frame 22 on the corresponding side of the upper and lower rotating shafts 21 and the first circular plate 20. Wheel 23 is fixedly connected to the corresponding rotating shaft 21. A third gear 24 is sleeved on the outside of the fixed rod 11. The third gear 24 is fixedly connected to the fixed rod 11. The second gear 23 meshes with the corresponding third gear 24. A support rod 25 is fixedly connected between the upper and lower support frames 22. The support rod 25 is fixedly connected to the inner wall of the stirring shaft 2. The support rod 25 has a U-shaped structure. There are three support rods 25, which are symmetrically distributed. The rotating shaft 21 is located between two adjacent support rods 25. When the stirring shaft 2 rotates, the stirring shaft 2 will drive the support frame 22 to rotate around the fixed rod 11 through the support rod 25. Under the action of the second gear 23 and the third gear 24, the rotating shaft 21 on the support frame 22 will drive the first circular plate 20 to rotate. The first circular plate 20 will press the inner wall of the first sliding groove 18 through the first sliding rod 19, thereby driving the movable block 17 and the rack 16 to move back and forth.

[0034] Furthermore, the second transmission mechanism 10 includes a mounting plate 26, which is fixedly connected to the material bucket 1. In this embodiment, one end of the mounting plate 26 is bent downward and fixed to the top of the material bucket 1 near the outer side. The other end of the mounting plate 26 is located above the top of the material bucket 1 and towards the center of the top of the material bucket 1. A second circular plate 27 is rotatably connected to the bottom of the other end of the mounting plate 26. A swing plate 28 is rotatably connected to the top of the material bucket 1 and below the second circular plate 27. A second sliding groove 29 is provided inside the swing plate 28. A second sliding rod 30 is slidably connected inside the second sliding groove 29. The top end of the second sliding rod 30 is fixedly connected to the second circular plate 27. The end of the swing plate 28 away from the stirring shaft 2 is rotatable by a positioning pin. The oscillating plate 28 is connected to the top of the material tank 1. An external gear ring 31 is fixedly connected to the outer end of the oscillating plate 28 near the stirring shaft 2. The top of the stirring shaft 2 extends upwards from the top of the material tank 1 and rotates with the top of the material tank 1. The top of the fixing rod 11 extends upwards from the top of the material tank 1 and rotates with the top of the material tank 1. A fourth gear 32 is fitted onto the top of the stirring shaft 2. The fourth gear 32 is fixedly connected to the stirring shaft 2 and meshes with the external gear ring 31. The center of the external gear ring 31 is the same as the center of the oscillating plate 28 when it oscillates back and forth. When the oscillating plate 28 oscillates back and forth, the external gear ring 31 rotates back and forth in both directions. At this time, the external gear ring 31 then drives the stirring shaft 2 to rotate back and forth in both directions through the fourth gear 32. In this embodiment, the fixing frame 12 is located above the fourth gear 32. One end of the fixing frame 12 is fixedly connected to the top of the fixing rod 11, and the other end of the fixing frame 12 extends outwards from the fourth gear 32 and bends downwards before being fixedly connected to the top of the material tank 1.

[0035] Furthermore, the second slide groove 29 has an arc-shaped structure. When the swing plate 28 swings back and forth, the center of the arc-shaped second slide groove 29 can coincide with the center of the second circular plate 27. When the center of the second slide groove 29 coincides with the center of the second circular plate 27, the second sliding rod 30 on the second circular plate 27 will not squeeze the inner wall of the second slide groove 29. At this time, the second circular plate 27 continues to rotate, and the swing plate 28 will not swing until the second sliding rod 30 moves from one end of the second slide groove 29 to the other end. Only then will the swing plate 28 start to swing.

[0036] Furthermore, a motor 33 is fixedly connected to the top of the mounting plate 26. The output shaft of the motor 33 extends vertically downward through the mounting plate 26 and reaches the bottom of the mounting plate 26. The output shaft of the motor 33 is rotatably connected to the mounting plate 26. The second circular plate 27 is fixedly connected to the output end of the motor 33. A control panel 34 is fixedly connected to the outside of the material bucket 1. The motor 33 is electrically connected to the control panel 34. The electrical equipment is powered by an external power source and controlled by the control panel 34. When the user starts the motor 33 through the control panel 34, the motor 33 will directly drive the second circular plate 27 to rotate. The second circular plate 27 squeezes the inner wall of the second slide groove 29 through the second slide rod 30, causing the swing plate 28 to swing back and forth. The swing plate 28 drives the stirring shaft 2 to rotate through the external gear ring 31 and the fourth gear 32. The stirring shaft 2 stirs the material through the first stirring rod 3, the second stirring rod 4 and the third stirring rod 5 to achieve the purpose of dispersion.

[0037] A method for using a device for uniformly dispersing lightweight energy-absorbing paste-like filling material hollow microspheres includes the following steps:

[0038] Step 1: In lightweight energy-absorbing paste filling materials, hollow microspheres are often used as core functional fillers. Due to their lightweight, hollow structure and excellent mechanical and physical properties, they can reduce the density of the paste material and significantly improve its energy absorption and buffering effect. They are widely applicable to scenarios such as mine filling and engineering protection where lightweight materials and impact resistance are required. Dispersion equipment is crucial to ensure the uniform dispersion of hollow microspheres in the paste and prevent agglomeration. During use, the motor 33 is started via the control panel 34. The motor 33 drives the second circular plate 27 to rotate, and the second circular plate 27 drives... The second slide bar 30 performs a circular motion. During this process, the second slide bar 30 will squeeze the inner wall of the second slide groove 29, thereby driving the swing plate 28 to swing back and forth. The swing plate 28 drives the outer gear ring 31 to rotate back and forth in both directions. The outer gear ring 31 drives the stirring shaft 2 to rotate back and forth in both directions through the fourth gear 32. Finally, the stirring shaft 2 drives the first stirring rod 3, the second stirring rod 4, and the third stirring rod 5 to stir the hollow microspheres in the material barrel 1 to achieve the purpose of dispersion. Since the second slide groove 29 has an arc-shaped structure, when the swing plate 28 swings to the second slide groove 29... When the center of the first circular plate 27 coincides with the center of the second circular plate 27, the second sliding rod 30 will not press against the inner wall of the second sliding groove 29, and the swing plate 28 will also remain stationary. Correspondingly, the stirring shaft 2 will also remain stationary, allowing the stirring shaft 2 to have a stirring mode that rotates from forward to pause and then to reverse. This stirring mode can improve the uniformity of stirring and avoid clumping. Because during ordinary unidirectional stirring, the material tends to follow the stirring shaft 2 in the same direction of circular motion, thus forming a relatively stable material flow. This will cause the material to not be fully cross-mixed. Reversing the direction can break this fixed flow. The direction of the stirring shaft 2 forces the materials to collide and interweave with each other. The pause allows the moving materials to be briefly buffered, avoiding continuous unidirectional movement due to inertia and creating better conditions for mixing during the reversal. At the same time, the bottom and edges of the material bucket 1 are difficult to reach with the force of the stirring shaft 2 during traditional unidirectional stirring, which can easily form dead corners. As a result, the materials in these areas cannot be stirred for a long time. When the reversal is performed, the direction of the force on the stirring shaft 2 changes, which can drive the materials that were originally in the dead corners to move towards the center. Combined with the pause, the materials in the dead corners can be further loosened and thus brought into the mixing system by the subsequent stirring action.

[0039] Step 2: During the rotation of the stirring shaft 2, the stirring shaft 2 drives the support frame 22 to rotate via the support rod 25, causing the rotating shaft 21 on the support frame 22 to revolve around the fixed rod 11. Simultaneously, the rotating shaft 21 also rotates on its own axis under the action of the second gear 23 and the third gear 24, causing the rotating shaft 21 to drive the first circular plate 20 to rotate. The first circular plate 20 then drives the first sliding rod 19 to perform circular motion. The first sliding rod 19, by pressing against the inner wall of the first sliding groove 18, drives the movable block 17 to move back and forth radially in the stirring shaft 2. The movable block 17 then drives the rack 16 to move back and forth. The rack 16, through the first gear 15, drives the rotating rod 14 to rotate back and forth in both directions. Finally, the rotating rod 14 drives the rotating frame 6 to swing back and forth. When the rotating frame 6 swings back and forth, it drives the second stirring rod 4 and the third stirring rod 5 to rotate via the first connecting rod 7. During the rotation of the second stirring rod 4 and the third stirring rod 5, the third stirring rod 5 will further rotate under the action of the second connecting rod 8, causing the second stirring rod 4 and the third stirring rod 5 to rotate. The third stirring rod 5 changes from a straight state to a bent state and then back to a straight state. Based on the rotational stirring, the downward bending of the second stirring rod 4 and the third stirring rod 5 achieves dynamic, multi-angle material tumbling, which greatly improves the stirring efficiency and uniformity. Because the stirring range of the traditional rigid stirring shaft 2 is fixed, it is easy to form stirring dead corners at the bottom and side walls of the material tank 1. However, the bendable structure of the second stirring rod 4 and the third stirring rod 5 can automatically bend and straighten when rotating, which can get closer to the bottom and side walls of the container, cover more space, and make the material mix more evenly. In addition, when the second stirring rod 4 and the third stirring rod 5 bend, they will form scraping and pushing actions at different angles, which will have a stronger shearing force on the material. The downward bending motion can turn the material at the bottom of the material tank 1 upward and press the upper layer of material downward, forming an upward and downward convection, avoiding material stratification. It is divided into two groups, one group rotating upward and the other group rotating downward, which can improve the tumbling effect and stirring uniformity.

8. A method for using a lightweight energy-absorbing paste filling material hollow microsphere uniform dispersion device, characterized in that, The method includes the following steps: Step 1: In the use of lightweight energy-absorbing paste filling material, the motor (33) is started through the control panel (34). The motor (33) drives the second circular plate (27) to rotate. The second circular plate (27) drives the second slide rod (30) to make a circular motion. During the process, the second slide rod (30) will squeeze the inner wall of the second slide groove (29), thereby driving the swing plate (28) to swing back and forth. The swing plate (28) drives the outer gear ring (31) to rotate back and forth in the forward and reverse directions. The outer gear ring (31) drives the stirring shaft (2) to rotate back and forth in the reverse and forward directions through the fourth gear (32). Finally, the stirring... The mixing shaft (2) drives the first mixing rod (3), the second mixing rod (4) and the third mixing rod (5) to stir the hollow microspheres in the material bucket (1) to achieve the purpose of dispersion. Since the second chute (29) is an arc-shaped structure, when the swing plate (28) swings to the point where the center of the second chute (29) coincides with the center of the second circular plate (27), the second sliding rod (30) will not squeeze the inner wall of the second chute (29). The swing plate (28) will also remain stationary at this time, and the mixing shaft (2) will also remain stationary, so that the mixing shaft (2) has a stirring mode from forward rotation to pause and then to reverse rotation. Step 2: During the rotation of the stirring shaft (2), the stirring shaft (2) will drive the support frame (22) to rotate through the support rod (25), causing the rotating shaft (21) on the support frame (22) to revolve around the fixed rod (11). At the same time, the rotating shaft (21) will also rotate on its own axis under the action of the second gear (23) and the third gear (24), causing the rotating shaft (21) to drive the first circular plate (20) to rotate. The first circular plate (20) will then drive the first sliding rod (19) to perform circular motion. The rod (19) drives the movable block (17) to move back and forth radially in the stirring shaft (2) by squeezing the inner wall of the first chute (18). The movable block (17) then drives the rack (16) to move back and forth. The rack (16) drives the rotating rod (14) to rotate back and forth in the forward and reverse directions through the first gear (15). Finally, the rotating rod (14) drives the rotating frame (6) to swing back and forth. When the rotating frame (6) swings back and forth, the rotating frame (6) will drive the second stirring rod (4) through the first connecting rod (7). As the second stirring rod (4) and the third stirring rod (5) rotate, the third stirring rod (5) will also rotate further under the action of the second connecting rod (8), so that the second stirring rod (4) and the third stirring rod (5) change from a straight state to a bent state, and then return to a straight state. On the basis of rotational stirring, dynamic and multi-angle material turning is achieved by bending the second stirring rod (4) and the third stirring rod (5) downward. The bendable structure of the second stirring rod (4) and the third stirring rod (5) can automatically bend and straighten when rotating. When the second stirring rod (4) and the third stirring rod (5) bend, scraping and pushing actions at different angles will be formed between the second stirring rod (4) and the third stirring rod (5). The downward bending motion can turn the material at the bottom of the material bucket (1) upward and press the upper material downward to form an upward and downward convection, avoid material stratification, and divide into two groups, one group rotating upward and the other group rotating downward.
