Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a high-speed dispersion device for polypropylene nanofillers. Background Technology

[0002] In the processing of polymer materials, especially in the preparation of composite materials requiring highly uniform dispersion, traditional mixing equipment often struggles to achieve comprehensive and deep mixing of materials within the container. This is primarily because conventional mixers typically employ a single or limited number of mixing shafts, resulting in a restricted mixing area and impacting the uniformity and efficiency of material dispersion. Particularly when processing high-viscosity polymers or those containing multiple components, inadequate mixing directly restricts the quality and performance of the final product.

[0003] For example, patent application number 202421306781.2 discloses a high-speed disperser for polymer materials. This utility model discloses a high-speed disperser for polymer materials, including: a stirring cylinder mechanism, a power mechanism, and a support mechanism; the stirring cylinder mechanism includes: a stirring cylinder sealing cover and a stirring cylinder body, and the interior of the stirring cylinder body is provided with a first stirring shaft, a second stirring shaft, a third stirring shaft, and a fourth stirring shaft arranged in a cross shape. Thus, in this utility model, the cross-shaped arrangement of the first, second, third, and fourth stirring shafts can expand the stirring range, ensuring that the material is fully mixed and dispersed in three-dimensional space, which is suitable for fine mixing of multiple components and greatly improves the consistency of product quality and performance stability. However, when this high-speed disperser for polymer materials is stirring, since it uses stirring rods for stirring and crushing, there are inevitably dead zones in the stirring, which affects the crushing and mixing efficiency of the material.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a high-speed dispersion device for polypropylene nanofillers. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-3 As shown, a high-speed dispersion device for polypropylene nanofillers includes a placement seat 1, a mixing cylinder 100 is provided on the upper surface of the placement seat 1, and a support frame 101 is provided on the rear surface of the placement seat 1. The surface of the support frame 101 is provided with a guide groove 103, and fixed feet 102 are provided on both sides of the rear surface of the support frame 101. This technical solution can improve the overall stability of the device when the mixing cylinder 100 is tilted and stirred by the fixed feet 102.

[0025] Furthermore, a support plate 2 is provided on the rear surface of the support frame 101, and a screw drive rod 201 is rotatably mounted on the inner surface of the support plate 2. With this technical solution, the mixing cylinder 100 can be lifted by screw drive to perform rotation and tilting operations.

[0026] Furthermore, a guide slide plate 202 is spirally mounted on the outer surface of the screw drive rod 201, and the guide slide plate 202 and the guide slide groove 103 are slidably connected. A servo motor 203 is also provided on the surface of the guide slide plate 202. With this technical solution, by setting the guide slide plate 202, when the mixing cylinder 100 is mixing materials, the screw drive rod 201 lifts the mixing cylinder 100 mounted on the guide slide plate 202 through the screw drive, and then drives the mixing cylinder 100 to rotate and tilt through the rotating rod 205, which optimizes the mixing trajectory of the stirring blades 303, reduces dead corners during material mixing, and adjusts the material residence time to improve crushing efficiency.

[0027] Furthermore, a reducer 204 is provided at the output end of the servo motor 203, and a rotating rod 205 is provided at the output end of the reducer 204. A connecting sleeve 206 is provided at the end of the rotating rod 205, and the connecting sleeve 206 is fixedly connected to the outer surface of the mixing cylinder 100. This technical solution can fix the mixing cylinder 100 by setting the connecting sleeve 206, and prevent the mixing cylinder 100 from loosening when tilted.

[0028] like Figures 4-5 As shown, a connecting cover 3 is installed on the upper surface of the mixing cylinder 100, and a servo motor 301 is provided on the upper surface of the connecting cover 3. A rotating rod 302 is provided at the output end of the servo motor 301, and a stirring blade 303 is provided on the outer surface of the rotating rod 302. In this technical solution, the stirring blade 303 can be used to stir and crush the material.

[0029] Furthermore, rotating sleeves 304 are provided on the outer surfaces of the upper and lower ends of the rotating rod 302, and support rods 305 are provided on the outer surface of the rotating sleeves 304. A slot 306 is provided on the end surface of the support rod 305, and a guide slide rod 307 is slidably installed through the inner surface of the slot 306. With this technical solution, the scraper 309 can be guided and slid by the guide slide rod 307.

[0030] Furthermore, a pressure relief spring 308 is provided on the outer surface of the guide slide rod 307, and a scraper 309 is provided at the end of the guide slide rod 307. The scraper 309 and the inner surface of the mixing cylinder 100 are connected by friction. With this technical solution, the scraper 309 can be used to scrape off the material adhering to the inner wall of the mixing cylinder 100 caused by the tilt of the mixing cylinder 100 when the mixing cylinder 100 is tilted and stirred. This improves the cleanliness of the inner wall surface of the mixing cylinder 100 and reduces material residue. With the pressure relief spring 308, the scraper 309 can be kept in contact with the inner surface of the mixing cylinder 100 by elastic reset. At the same time, the scraper 309 can be protected by elastic compression when it encounters large fluctuations.

[0031] Working principle: When using this high-speed dispersion equipment for polypropylene nanofillers, firstly, the material to be processed is placed in the mixing cylinder 100, and then the mixing cylinder is sealed by the connecting cover 3, which is equipped with a servo motor 301. After sealing is completed, the servo motor 301 is started, and its power is transmitted to the rotating rod 302, which drives the stirring blades 303 to rotate at high speed, so as to fully stir and crush the material.

[0032] After the initial mixing achieves the desired effect, the screw drive rod 201 is activated. The rotation of the screw drive rod 201 drives the guide slide plate 202 on its outer surface, causing it to move upward along the guide groove 103 opened on the surface of the support frame 101. When the mixing cylinder 100 rises to a suitable height, the servo motor 203 is activated. The power of the servo motor 203 is reduced and amplified by the reducer 204, driving the mixing cylinder 100 to rotate and tilt. At this time, the stirring blades 303 continue to work, mixing the material at multiple angles, significantly improving the mixing efficiency.

[0033] To address the issue of materials adhering to the inner wall of the mixing cylinder 100 due to electrostatic attraction, the scraper 309 is connected to the rotating rod 205 via a pressure relief spring 308, ensuring that the scraper 309 remains in close contact with the inner surface of the mixing cylinder 100. As the rotating rod 205 rotates, the scraper 309 continuously scrapes away the material adhering to the inner wall. When encountering stubborn clumps, the pressure relief spring 308 compresses and deforms, causing the guide rod 307 to slide inward, resulting in a rebound action of the scraper 309. This effectively removes stubborn clumps while protecting the scraper 309 from damage. This is the working principle of this high-speed dispersion equipment for polypropylene nanofillers.
