Abstract
Description
Technical Field
[0001] This utility model belongs to the field of material mixing technology, and relates to a mixing device for ultrafine talc powder and polypropylene material. Background Technology
[0002] In the plastics processing industry, polypropylene (PP) is a commonly used thermoplastic resin with advantages such as low density, good mechanical properties, and strong chemical resistance. To improve the performance of polypropylene materials, various fillers are often added, and ultrafine talc is one such commonly used filler. The addition of ultrafine talc can improve the rigidity, heat resistance, and dimensional stability of polypropylene materials. However, due to its small particle size, ultrafine talc is prone to agglomeration. If the mixing is uneven when mixed with polypropylene materials, it will affect the material's performance. Currently, existing mixing devices typically use simple stirring methods when mixing ultrafine talc with polypropylene materials, resulting in poor stirring effects and a tendency for uneven mixing.

Detailed Implementation
[0025] The present invention will be further described below with reference to the accompanying drawings.
[0026] like Figures 1-5As shown, a mixing device for ultrafine talc powder and polypropylene includes a main body 1. The main body 1 includes a machine support 2, a material mixing box 3, a feeding mechanism, and a discharging mechanism 4. The material mixing box 3 is installed above the machine support 2. The feeding mechanism is located at the top of the material mixing box 3, and the discharging mechanism 4 is located on one side of the material mixing box 3. The material mixing box 3 includes an outer static box 5 and an inner movable box 6. The inner movable box 6 is located inside the outer static box 5. The outer static box 5 and the inner movable box 6 are cylindrical structures. A stirring motor 7 is installed on one side of the inner movable box 6. The output end of the stirring motor 7 is connected to a stirring assembly 8, which is movably installed inside the inner movable box 6. A swinging mechanism is installed at the bottom of the inner movable box 6.
[0027] Furthermore, the swing mechanism includes a swing motor 9, a fixed base 10, and a transmission rod 11. The swing motor 9 is fixedly installed inside the body support 2. The fixed base 10 is located on both sides of the upper surface of the body support 2. A connecting block 12 is fixedly installed at the bottom of the inner movable box 6. A rotating shaft 13 is provided on the connecting block 12. One end of the rotating shaft 13 is movably hinged to the fixed base 10.
[0028] In this embodiment, when the swing motor 9 is started, the transmission rod 11 drives the connecting block 12 and the inner movable box 6 to swing. This swing design allows the material in the inner movable box 6 to swing back and forth while being stirred, further enhancing the uniformity of the material mixing.
[0029] Furthermore, the transmission rod 11 is located below the connecting block 12, and both ends of the transmission rod 11 are fixedly connected to the connecting block 12 respectively. A slide rod 14 is fixedly provided in the middle of the transmission rod 11, and a connecting sleeve 16 is sleeved on the slide rod 14. The connecting sleeve 16 is slidably connected to the slide rod 14, and a cylindrical rod 15 is fixedly installed at the bottom of the connecting sleeve 16.
[0030] In this embodiment, the transmission rod 11, driven by the swing motor 9, not only drives the connecting block 12 and the inner movable box 6 to swing, but also increases the stability and flexibility of the swing through the sliding connection of the slide rod 14 and the connecting sleeve 16.
[0031] Furthermore, a rotating rod 17 is fixedly mounted on the output shaft of the rocking motor 9, and one end of the rotating rod 17 is sleeved on the cylindrical rod 15.
[0032] In this embodiment, when the swing motor 9 is started, its output shaft drives the rotating rod 17 to rotate. One end of the rotating rod 17 is sleeved on the cylindrical rod 15. This design allows the cylindrical rod 15 and the connected sleeve 16, slide rod 14 and transmission rod 11 to follow the rotation of the rotating rod 17 and produce a certain swing or rotation effect.
[0033] Furthermore, the feeding mechanism includes a first feeding funnel 18 and a second feeding funnel 19. The first feeding funnel 18 is fixedly installed on the top of the outer static box 5, and the second feeding funnel 19 is fixedly installed on the top of the inner movable box 6. A material outlet 20 is fixed at the bottom of the first feeding funnel 18, and the material outlet 20 is located above the second feeding funnel 19.
[0034] In this embodiment, the material can easily enter the inner movable box 6 through the first feeding funnel 18 and the second feeding funnel 19. The first feeding funnel 18 is fixed and convenient for feeding, while the second feeding funnel 19 is movable and inconvenient for feeding.
[0035] Furthermore, the discharge mechanism 4 includes a discharge pipe 21 and a discharge valve 22. The discharge pipe 21 is located on one side of the bottom of the inner movable box 6, and the discharge valve 22 is located on the discharge pipe 21.
[0036] In this embodiment, the discharge of the mixed ultrafine talc powder and polypropylene material can be easily controlled. The discharge valve 22 can be opened or closed as needed to achieve quantitative discharge of the material or to stop the discharge.
[0037] Furthermore, the discharge pipe 21 is fixedly installed on one side of the inner movable box 6, and the outer static box 5 has a slot for the discharge pipe 21 to move.
[0038] In this embodiment, the slots on the outer static housing 5 allow the discharge pipe 21 to remain connected when the movable housing moves, ensuring the continuity of material discharge.
[0039] Furthermore, the stirring assembly 8 includes a stirring shaft 23 and stirring blades. The output shaft of the stirring motor 7 is connected to the stirring shaft 23. One end of the stirring shaft 23 extends into the inner movable housing 6, and the stirring blades are arranged on the stirring shaft 23.
[0040] Furthermore, the stirring blades include a main stirring blade 24 and a secondary stirring blade 25. The main stirring blade 24 is spiral-shaped, and the secondary stirring blade 25 is inclined. The main stirring blade 24 and the secondary stirring blade 25 are arranged alternately.
[0041] In this embodiment, the synergistic effect of the main stirring blade 24 and the auxiliary stirring blade 25 also enhances the stirring effect and improves the mixing efficiency, so that the ultrafine talc powder and polypropylene material can be mixed more thoroughly and evenly.
[0042] Furthermore, support rods 26 are fixedly installed on both sides of the stirring shaft 23, and scraper 27 is fixedly installed on the top of the support rods 26. The scraper 27 is in contact with the inner wall of the inner movable box 6.
[0043] In this embodiment, the scraper 27 is provided to clean the inner wall of the inner movable box 6 during the mixing process, preventing the ultrafine talc powder and polypropylene material from adhering to the inner wall, and ensuring the uniformity of mixing and the cleanliness of the device.
[0044] The working principle of this utility model is as follows:
[0045] In use, ultrafine talc powder and polypropylene material are added to the material mixing box 3 through the first feed funnel 18. The stirring motor 7 is started, driving the stirring shaft 23 to rotate, which in turn drives the stirring blades to stir. Simultaneously, the swing motor 9 is started. Through the coordinated action of the transmission rod 11, slide rod 14, connecting sleeve 16, and cylindrical rod 15, the swing motor 9 drives the inner movable box 6 to swing. This combined swinging and stirring action ensures that the materials are fully mixed and evenly distributed in the mixing box. When the desired mixing degree is reached, the stirring motor 7 and swing motor 9 are turned off, and the discharge valve 22 is opened, allowing the mixed material to be discharged through the discharge pipe 21.
