Description

Technical Field

[0001] This utility model relates to the field of silicone rubber processing technology, and in particular to a silicone rubber mixed filler dispersion device with integrated ultrasonic pretreatment. Background Technology

[0002] Silicone rubber filler refers to a mixture of various solid particulate substances added to the silicone rubber matrix material to improve the mechanical and physical properties of silicone rubber or reduce production costs. Common fillers include silica, calcium carbonate, titanium dioxide, and glass microspheres. When different fillers are mixed in a specific ratio, they can give silicone rubber different functional properties to meet the application needs of different scenarios. In the production of silicone rubber, dispersion equipment is required to uniformly disperse the mixed fillers into the silicone rubber matrix. If the fillers are not dispersed evenly, it will lead to problems such as performance fluctuations and local defects in the finished silicone rubber product. Therefore, dispersion equipment is a key piece of equipment in silicone rubber processing. Its main function is to break up filler agglomerates through stirring, shearing, grinding and other actions, so that the filler particles are evenly distributed in the silicone rubber matrix, ensuring the performance stability of the finished product.

[0003] The existing technology has the following shortcomings: Existing dispersion equipment lacks a targeted pretreatment structure for the filler. Before entering the dispersion stage, the mixed filler is prone to agglomeration due to interparticle forces. Relying solely on a single stirring structure within the dispersion tank is insufficient to completely break up these agglomerates, leading to localized clumping when the silicone rubber matrix and filler are mixed. This results in significant fluctuations in the mechanical properties of the final product, failing to meet the requirements of high-precision applications. Furthermore, the filler distribution and stirring dispersion stages in existing devices are independent. After entering the dispersion tank, the filler tends to accumulate in localized areas. Moreover, the stirring structures are mostly based on single revolution or rotation, which limits the mixing coverage of high-viscosity silicone rubber and filler, easily creating dead zones and resulting in insufficient mixing in some areas. Additionally, during the dispersion process, materials tend to adhere to the inner wall of the equipment, causing raw material waste and affecting the dispersion effect of subsequent batches. Utility Model Content

[0004] This invention proposes a silicone rubber mixed filler dispersion device with integrated ultrasonic pretreatment. The pretreatment component achieves efficient dispersal of filler agglomerates, and the material distribution component distributes the material evenly, while the stirring component disperses the material through both revolution and rotation. This improves the mixing uniformity and dispersion efficiency, reduces material waste, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a silicone rubber mixed filler dispersion device with integrated ultrasonic pretreatment, comprising a dispersion tank, a discharge port provided at the bottom center of the dispersion tank, a top cover fixedly installed at the top of the dispersion tank, a silicone rubber inlet provided on the top right side of the top cover, a pretreatment component fixedly connected to the top center of the top cover, a material distribution component provided at the bottom center of the top cover, and a stirring component provided at the bottom of the material distribution component.

[0006] The pretreatment assembly includes a pretreatment tank, which is fixedly connected to the top center of the top cover. A filler inlet is provided on the front side of the top of the pretreatment tank. A first motor is fixedly connected to the top center of the pretreatment tank. The output shaft of the first motor passes through the inside of the pretreatment tank and is fixedly connected to a rotating plate. Ultrasonic vibration rods are fixedly installed on both the left and right ends of the bottom of the rotating plate. Several protrusions are provided on the outer surface of the ultrasonic vibration rods.

[0007] Preferably, the top cover has a through groove running vertically through the middle, and the top of the through groove is connected to the bottom of the pretreatment component.

[0008] Preferably, the fabric assembly includes a rotating tube, which is rotatably connected to the bottom end of the inner surface of the communicating groove, and a plurality of diversion tubes are fixedly connected to the bottom end of the rotating tube in a ring array.

[0009] Preferably, the fabric assembly further includes a second motor, the output shaft of which extends through to the bottom of the top cover and is fixedly connected to a rotating wheel.

[0010] Preferably, a transmission gear ring is fixedly connected to the outer surface of the rotating tube, and the outer surface of the rotating wheel meshes with the outer surface of the transmission gear ring.

[0011] Preferably, the stirring assembly includes a stirring shaft, the top end of which is fixedly connected to the middle of the lower surface of the rotating plate, and the bottom end of which extends into the interior of the dispersion tank and is fixedly connected to a rotating platform.

[0012] Preferably, the center of the rotating platform is rotatably connected to a rotating shaft that runs through the left and right sides, and stirring blades are fixedly connected to both the left and right sides of the outer surface of the rotating shaft.

[0013] Preferably, a bevel gear is fixedly connected to the middle of the outer surface of the rotating shaft, and a movable groove is provided in the middle of the rotating table, with the bevel gear rotatably connected inside the movable groove.

[0014] Preferably, a connecting cylinder is rotatably connected to the outer surface of the stirring shaft, and the top end of the connecting cylinder is fixedly connected to the bottom end of the rotating tube.

[0015] Preferably, a bevel gear ring is fixedly connected to the bottom end of the connecting cylinder, and the bevel gear ring is rotatably connected to the upper surface of the rotating platform and its outer surface meshes with the outer surface of the bevel gear.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. In this utility model, through the cooperation between the first motor, rotating plate, ultrasonic vibrating rod, protrusion and connecting groove in the pretreatment component, the first motor drives the rotating plate to rotate the ultrasonic vibrating rod in the pretreatment tank. The ultrasonic vibrating rod generates high-frequency vibration, which, together with the protrusion on the outer surface, forms a physical impact on the filler. At the same time, the rotational motion expands the ultrasonic action range. The pretreated filler enters the feeding component through the connecting groove. This structure can completely break up the agglomerates in the mixed filler, solving the problem of filler clumping caused by the lack of pretreatment in existing equipment. This ensures the uniformity of subsequent mixing with the silicone rubber matrix, reduces the fluctuation of finished product performance, and meets the requirements of high-precision applications. At the same time, the protrusion enhances the breaking effect on stubborn agglomerates and avoids the blind zone of ultrasonic vibration.

[0017] 2. In this utility model, through the mutual cooperation between the second motor, rotating wheel, transmission gear ring, rotating tube, and diverter pipe in the material distribution assembly and the stirring shaft, rotating table, rotating shaft, stirring blades, connecting cylinder, bevel gear ring, and bevel gear in the stirring assembly, the second motor drives the rotating wheel to rotate, which in turn drives the rotating tube to rotate. The rotating tube drives the diverter pipe to evenly distribute the filler into the dispersion tank. At the same time, the rotating tube drives the bevel gear ring to rotate through the connecting cylinder. The bevel gear ring meshes and drives the bevel gear to rotate the rotating shaft, so that the stirring blades rotate on their own axis while revolving with the rotating table. The material distribution assembly can avoid local accumulation of filler. The revolution and rotation of the stirring assembly cover all areas in the dispersion tank, solving the problem of dead zones in existing equipment and improving mixing efficiency. At the same time, the turbulence effect formed by the dual motion enhances the shear mixing effect between the silicone rubber matrix and the filler, reduces the adhesion of materials to the tank wall, and reduces the waste rate of raw materials.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, this utility model provides a technical solution: it includes a dispersion tank 1, a discharge port 2 at the bottom center of the dispersion tank 1, a top cover 3 fixedly installed at the top of the dispersion tank 1, a silicone rubber inlet 4 at the top right side of the top of the top cover 3, a pretreatment component 5 fixedly connected to the top center of the top of the top cover 3, a material distribution component 6 at the bottom center of the top of the top cover 3, and a stirring component 7 at the bottom of the material distribution component 6. The pretreatment component 5 includes a pretreatment tank 51, which is fixedly connected to the top center of the top of the top cover 3. A filler inlet 52 is provided on the front side of the top of the pretreatment tank 51. A first motor 53 is fixedly connected to the top center of the pretreatment tank 51. The output shaft of the first motor 53 passes through the inner side of the pretreatment tank 51 and is fixedly connected to a rotating plate 54. Ultrasonic vibration rods 55 are fixedly installed at both the left and right ends of the bottom of the rotating plate 54. Several protrusions are provided on the outer surface of the ultrasonic vibration rods 55. A through groove 31 is opened in the middle of the top cover 3. The top end of the through groove 31 is connected to the bottom end of the pretreatment component 5. The fabric assembly 6 includes a rotating tube 61. The rotating tube 61 is rotatably connected to the bottom end of the inner surface of the through groove 31. Several diversion tubes 62 are fixedly connected in a ring array at the bottom end of the rotating tube 61. The fabric assembly 6 also includes a second motor 64. The output shaft of the second motor 64 passes through to the bottom of the top cover 3 and is fixedly connected to a rotating wheel 65. A transmission gear ring 63 is fixedly connected to the outer surface of the rotating tube 61. The outer surface of the rotating wheel 65 is meshed with the outer surface of the transmission gear ring 63. The overall effect achieved in Embodiment 1 is as follows: When the mixed packing enters the pretreatment tank 51 from the packing inlet 52, the first motor 53 starts and drives the rotating plate 54 connected to the output shaft to rotate inside the pretreatment tank 51. The rotating plate 54 synchronously drives the ultrasonic vibration rods 55 at the bottom left and right ends to rotate together. At this time, the ultrasonic vibration rods 55 are energized to generate high-frequency vibration. Several protrusions on their outer surface continuously contact and collide with the mixed packing in the pretreatment tank 51 as the ultrasonic vibration rod vibrates and rotates, forming a physical impact on the agglomerates formed by the interparticle forces in the packing. Combined with the high-frequency vibration, the agglomerates are completely broken up. At the same time, the connecting groove 31 in the middle of the top cover 3... The bottom of the pretreatment tank 51 is connected to the top of the rotating tube 61, so that the pretreated and dispersed filler can fall smoothly into the rotating tube 61. Then, the second motor 64 of the feeding assembly 6 starts, driving the rotating wheel 65 connected to the output shaft to rotate. The rotating wheel 65 drives the rotating tube 61 sleeved at the bottom of the connecting groove 31 to rotate through meshing with the transmission gear ring 63. The rotating tube 61 synchronously drives the rotation of several diversion tubes 62 in the annular array at the bottom, so that the filler in the tube is evenly thrown into different areas of the dispersion tank 1 through multiple diversion tubes 62, avoiding the filler from accumulating in a local area of ​​the dispersion tank 1, and providing a uniform material distribution basis for the subsequent mixing and dispersion of silicone rubber matrix and filler.

[0023] Example 2: Figure 3 , Figure 4 and Figure 5As shown, this utility model provides a technical solution: the stirring assembly 7 includes a stirring shaft 71, the top end of the stirring shaft 71 is fixedly connected to the middle of the lower surface of the rotating plate 54, the bottom end of the stirring shaft 71 penetrates into the interior of the dispersion tank 1 and is fixedly connected to a rotating platform 72, the middle of the rotating platform 72 is rotatably connected to a rotating shaft 73 that passes through from left to right, stirring blades 74 are fixedly connected to both sides of the outer surface of the rotating shaft 73, a bevel gear 77 is fixedly connected to the middle of the outer surface of the rotating shaft 73, a movable groove is opened in the middle of the rotating platform 72, the bevel gear 77 is rotatably connected to the interior of the movable groove, a connecting cylinder 75 is rotatably connected to the outer surface of the stirring shaft 71, the connecting cylinder 75 rotates in the opposite direction to the stirring shaft 71, the top end of the connecting cylinder 75 is fixedly connected to the bottom end of the rotating tube 61, a bevel gear ring 76 is fixedly connected to the bottom end of the connecting cylinder 75, the bevel gear ring 76 is rotatably connected to the upper surface of the rotating platform 72 and its outer surface meshes with the outer surface of the bevel gear 77; The overall effect achieved in Embodiment 2 is as follows: when the stirring shaft 71 rotates synchronously with the rotating plate 54, the rotating platform 72 fixed at its bottom rotates around the axis of the stirring shaft 71. The rotating platform 72 synchronously drives the rotating shaft 73 connected in the middle and the stirring blades 74 on both sides of the rotating shaft to revolve around the stirring shaft 71. At the same time, the top of the connecting cylinder 75 is fixed to the bottom of the rotating tube 61. As the rotating tube 61 rotates, it synchronously drives the bevel gear ring 76 at its bottom to rotate on the upper surface of the rotating platform 72. The bevel gear ring 76 meshes with the bevel gear 77 through the teeth on its outer surface, driving the bevel gear 77 to move in the movable groove of the rotating platform 72. The rotating bevel gear 77 synchronously drives the centrally fixed rotating shaft 73 to rotate, which in turn drives the stirring blades 74 on both sides to rotate around the axis of the rotating shaft 73. The dual motion of the stirring blades 74, which revolves and rotates, can cover all areas from the center to the edge and from the top to the bottom of the dispersion tank 1, completely eliminating the stirring dead zones that exist in traditional single-motion stirring. At the same time, the complex turbulence formed by the dual motion enhances the shearing and kneading effect on the high-viscosity silicone rubber and fillers, further breaking down any possible residual micro-agglomerates, improving the uniformity of the mixture, accelerating the mixing and dispersion speed, and improving the overall dispersion efficiency.

[0024] The working principle of the entire equipment is as follows: During use, the mixed packing is first fed into the pretreatment tank 51 through the packing inlet 52, and the silicone rubber matrix is ​​injected into the dispersion tank 1 through the silicone rubber inlet 4. The first motor 53 and the ultrasonic vibrating rod 55 are started. The first motor 53 drives the rotating plate 54 to rotate, which in turn drives the ultrasonic vibrating rod 55 to rotate within the pretreatment tank 51. The ultrasonic vibrating rod 55 generates high-frequency vibration, and its outer surface protrusions continuously impact the mixed packing, thoroughly breaking up the agglomerates. The pretreated packing enters the rotating tube 61 through the connecting groove 31. Simultaneously, the second motor 64 is started, driving the rotating wheel 65 to rotate. The rotating wheel 65 drives the rotating tube 61 and the diversion tube 62 to rotate through the transmission gear ring 63, thus dispersing the packing... The material is evenly distributed into the dispersion tank 1 through multiple diversion pipes 62, making initial contact with the silicone rubber matrix. When the rotating plate 54 rotates, it synchronously drives the stirring shaft 71 to rotate. The stirring shaft 71 drives the rotating table 72 and the stirring blades 74 to revolve around the stirring shaft 71. When the rotating pipe 61 rotates, it drives the connecting cylinder 75 and the bevel gear ring 76 to rotate. The bevel gear ring 76 meshes and drives the bevel gear 77 and the rotating shaft 73 to rotate, so that the stirring blades 74 rotate around the rotating shaft 73 while revolving around the rotating shaft. Through the dual motion, the silicone rubber matrix and the filler are sheared and mixed in all directions, eliminating the stirring dead zone and reducing the adhesion of materials to the inner wall of the dispersion tank 1. After the mixing and dispersion are completed, the discharge port 2 is opened, and the dispersed material is discharged from the discharge port 2, completing the entire dispersion operation.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
