Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, and more specifically, to a mixing device for modifying plastics. Background Art

[0002] Modified plastics refer to general-purpose and engineering plastics that have been processed and modified through methods such as filling, blending, and reinforcement to achieve superior properties. These properties include flame retardancy, strength, impact resistance, and toughness. Existing mixing devices for modified plastics do exhibit some significant shortcomings. These devices typically rely on the rotation of a stirring rod to mix the materials, but this process presents several key issues. First, as the stirring rod rotates within the mixing chamber, some of the material adheres to the inner walls of the mixing chamber due to centrifugal force, static electricity, or viscosity. Over time, this sticky material accumulates, forming a layer of difficult-to-remove residue. This not only reduces the final amount of mixed material, impacting production efficiency and cost control, but can also reduce mixing uniformity, thus affecting product quality. More seriously, if these materials adhered to the inner walls for a long time are not promptly cleaned, they will gradually deteriorate and contaminate the material. During the continuous production process, these residues may fall off and mix into the next batch of material, contaminating the purity of the next batch. This cross-contamination not only reduces the overall quality of the product, but may also have unpredictable effects on the performance of the final product, especially in the field of modified plastics where purity and performance are extremely high requirements.

[0021] When in use, the material is placed into the mixing box 1 through the feeding box 2, and then the staff starts the driving motor 7 through the external switch. The power generated by the driving motor 7 causes the main gear 6 to rotate. Since the main gear 6 and the slave gear 5 are engaged, the main gear 6 drives the slave gear 5 to rotate synchronously while rotating. The rotation of the slave gear 5 causes the rotating rod 3 to rotate through the connecting shaft 4, and the fixed rod 9 on the surface of the rotating rod 3 also rotates synchronously. The rotation of the fixed rod 9 fully mixes the material inside the mixing box 1. While the rotating rod 3 rotates, the scraper 10 at one end of the fixed rod 9 moves on the inner wall of the mixing box 1, thereby scraping off the material on the inner wall of the mixing box 1;

[0022] The power of the driving motor 7 causes the slave gear 5 meshing with the main gear 6 to rotate, and the rotation of the slave gear 5 causes the rotating rod 3 to rotate, and the rotation of the fixed rod 9 mixes the materials inside the mixing box 1. At the same time, the scraper 10 moves on the inner wall of the mixing box 1 to scrape the materials on the inner wall of the mixing box 1. Compared with the traditional device, this device can efficiently transfer raw materials such as modifiers and fillers from one place to another and mix them with other materials, thereby ensuring rapid and uniform mixing of raw materials, thereby improving production efficiency. At the same time, through the scraping action of the scraper 10, the residual material attached to the inner wall of the mixing box 1 can be effectively removed, thereby reducing material waste and ensuring the purity of the next mixing. Through efficient mixing and timely cleaning, the uniformity and consistency of the modified plastic can be ensured, thereby improving the quality and performance of the product.

[0023] Among them, a feeding pipe 11 is fixedly installed on the right surface of the mixing box 1, a discharge pipe 12 is fixedly installed on the bottom of the feeding pipe 11, a movable rod 13 is movably installed inside the feeding pipe 11, and a spiral feeding blade 14 is fixedly installed on the surface of the movable rod 13. A second driving motor 15 is fixedly installed on the right side of the feeding pipe 11, and the output shaft of the second driving motor 15 is fixedly connected to one end of the movable rod 13;

[0024] After the materials in the mixing box 1 are fully mixed, the staff starts the second drive motor 15. The power generated by the second drive motor 15 causes the movable rod 13 to rotate. The rotation of the movable rod 13 causes the spiral conveying blade 14 to rotate synchronously. During the rotation process, the spiral conveying blade 14 brings the raw materials in the mixing box 1 into the gap between the spiral conveying blades 14 and the spiral conveying blades 14 and continuously moves to the top of the discharge pipe 12, and is collected through the inside of the discharge pipe 12.

[0025] The power of the driving motor 2 15 causes the spiral conveying blades 14 on the surface of the movable rod 13 to rotate. The rotation of the spiral conveying blades 14 brings the material into the gap between the spiral conveying blades 14 and moves it to the top of the discharge pipe 12 for collection. Compared with the traditional device, this device has the characteristics of large conveying capacity, can realize the rapid transportation of a large amount of material, and can accurately control the amount of material conveyed, meeting the continuity and stability requirements in the production of modified plastics. In addition, this device has a simple structure, a long service life, and little destructive force on the material, and can maintain the integrity of the material, which means that in the process of conveying the modified plastics, the properties and quality of the material are well maintained.

[0026] Among them, three groups of legs 22 are fixedly installed on the bottom of the mixing box 1, and foot pads 23 are fixedly installed on the bottom of the three groups of legs 22;

[0027] Three groups of legs 22 are fixedly mounted on the bottom of the mixing box 1 , and foot pads 23 are fixedly mounted on the bottoms of the three groups of legs 22 . The foot pads 23 can disperse the pressure from above, thereby improving the stability of the device during operation.

[0029] A movable plate 16 and a movable plate 2 17 are movably installed inside the feeding box 2 and are in a relative state. A spring 18 is provided between the front end of the movable plate 16 and the movable plate 2 17 and the inner wall of the feeding box 2. This design can realize automatic unloading, and after unloading, the movable plate 16 and the movable plate 2 17 are closed to prevent external impurities from entering the interior of the mixing box 1.

[0030] Among them, a motor protection cover 19 is provided on the top of the main gear 6, and the drive motor 1 7 is located inside the motor protection cover 19, and a heat dissipation hole 20 is opened on the surface of the motor protection cover 19;

Stainless steel has high strength and is not easy to rust, thereby increasing the service life of the mixing box 1.

[0034] The working principle and use process of this utility model:

[0035] During use, the material is placed into the mixing box 1 through the feeding box 2, and then the staff starts the driving motor 7 through the external switch. The power generated by the driving motor 7 causes the main gear 6 to rotate. Since the main gear 6 and the slave gear 5 are engaged, the main gear 6 drives the slave gear 5 to rotate synchronously while rotating. The rotation of the slave gear 5 causes the rotating rod 3 to rotate through the connecting shaft 4, and the fixed rod 9 on the surface of the rotating rod 3 also rotates synchronously. The material inside the mixing box 1 is fully mixed by the rotation of the fixed rod 9. While the rotating rod 3 rotates, the scraper 10 at one end of the fixed rod 9 moves on the inner wall of the mixing box 1, thereby scraping off the material on the inner wall of the mixing box 1.

[0036] After the materials inside the mixing box 1 are fully mixed, the staff starts the driving motor 2 15. The power generated by the driving motor 2 15 causes the movable rod 13 to rotate. The rotation of the movable rod 13 causes the spiral feeding blade 14 to rotate synchronously. During the rotation process, the spiral feeding blade 14 brings the raw materials inside the mixing box 1 into the gap between the spiral feeding blades 14 and the spiral feeding blades 14 and continuously moves to the top of the discharge pipe 12, and collects it through the inside of the discharge pipe 12.
