Description

Technical Field

[0001] The utility model relates to the technical field of polymer material processing, in particular to a device for uniformly dispersing polymer material particles. Background Art

[0002] Traditional dispersion devices generally face problems such as uneven particle dispersion, high breakage rate caused by fast falling speed, and complex structure and difficult maintenance. These problems not only affect the efficiency and quality of polymer material processing, but also increase production costs and maintenance difficulties.

[0003] In the prior art, traditional devices often lack an effective dispersion mechanism, resulting in easy concentration and accumulation of particles during the falling process, affecting subsequent processing effects. The too-fast falling speed of particles not only increases the risk of particle breakage, but also may lead to uneven distribution of materials on the conveyor belt, affecting product quality. Some traditional devices are complex in design and have many components, which not only increase the manufacturing cost, but also bring inconvenience to daily maintenance. Consistent with conventional technologies, they have poor practicability. Therefore, the utility model discloses a device for uniformly dispersing polymer material particles to solve the problems of uneven dispersion, fast falling speed, and complex structure existing in traditional polymer material particle dispersion devices. Summary of the Utility Model

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer and more understandable, the following further elaborates on this utility model in combination with specific embodiments.

[0022] This utility model provides a Figures 1 to 4 kind of polymer material particle uniform dispersion device as shown in the figure, including: two groups of mounting frames 1, four groups of support columns 2 are installed at the lower ends of the mounting frames 1, rotating rollers are installed on the opposite side walls of the mounting frames 1, a conveyor belt 3 is jointly installed on the rotating rollers, multiple groups of first circular convex blocks 4 are installed on the surface of the conveyor belt 3, and grid baffles 5 are installed on both side edges at the two ends of the conveyor belt 3; a dispersion device is installed on the assembly frame 6; the dispersion device is used to uniformly disperse the polymer material falling onto the conveyor belt 3. With the design of the teat-shaped column 21, the arc-shaped groove 20, and the arc-shaped ramp, the polymer material particles can slowly slide down on the loading round block 18, avoiding the problem of concentrated accumulation of particles due to direct impact in the traditional method, and realizing the uniform dispersion of particles. By driving the rotating shaft 13 and the mounting strip 14 to rotate through the servo motor 19, the falling speed of the particles is further finely adjusted to ensure that the particles fall onto the conveyor belt 3 at a more gentle and uniform speed, improving the consistency and stability of subsequent processing. The mounting strip 14 made of soft rubber material and the carefully designed inclined surface and the second circular convex block 16 effectively reduce the impact force of the particles during the falling process, reduce the particle breakage rate, and ensure the quality of the material. The dispersion device is fixed to the mounting plate 7 by screws 8, which is convenient for disassembly, cleaning, and maintenance. At the same time, the overall design is compact, occupies a small area, and is suitable for various production environments.

[0023] Furthermore, in this example, as Figure 2 , Figure 3 and Figure 4As shown in the figure, the dispersion device includes a mounting plate 7, which is mounted on the cross arm of the assembly frame 6. Screws 8 are installed at both ends of the mounting plate 7. Thread grooves that match the screws 8 are provided at the positions corresponding to the screws 8 on both the mounting plate 7 and the assembly frame 6. A rib plate 10 is installed on the upper end surface of the screw 8. A cylinder 9 is installed on the side wall of the rib plate 10. A cover plate 11 is installed at the top of the cylinder 9. A circular hole is provided in the middle of the cover plate 11. An inlet 12 is installed at the upper end of the circular hole. The upper end of the inlet 12 is in an upward trumpet shape. Four groups of mounting rods 17 are installed around the circular hole at the lower end of the cover plate 11. A loading round block 18 is jointly installed at the lower ends of the mounting rods 17. A nipple-shaped cylinder 21 is installed in the middle of the top of the loading round block 18. An arc-shaped groove 20 is provided at the connection between the loading round block 18 and the nipple-shaped cylinder 21. The edge of the loading round block 18 is provided with a downward arc-shaped ramp, and the upper end of the arc-shaped ramp is connected to the edge of the arc-shaped groove 20. A groove is provided in the middle of the bottom end of the loading round block 18. A servo motor 19 is installed in the groove. A rotating shaft 13 is installed at the output end of the servo motor 19. A plurality of mounting strips 14 are installed on the side of the rotating shaft 13. The mounting strips 14 are made of soft rubber strips. A circular ring 15 is installed on the upper part of the inner wall of the cylinder 9 below the loading round block 18. An inclined surface from the outside to the inside is provided at the edge of the middle of the top of the circular ring 15. A plurality of second circular bumps 16 are installed on the inclined surface. A bottom plate 22 is installed on the inner wall of the bottom end of the cylinder 9. The bottom plate 22 is provided with a ramp along the direction of the conveyor belt 3, and there is a gap between the bottom of the ramp and the inner wall of the cylinder 9. The polymer material particles are first introduced into the inlet 12 at the top of the cylinder 9. The inlet 12 adopts a unique upward trumpet-shaped design, which not only increases the contact area of the particles but also guides the particles to fall into the interior of the cylinder 9 in a more uniform manner. At the moment when the particles enter the cylinder 9, due to the shape and size of the inlet 12, slight collisions and frictions will occur between the particles, thus achieving a preliminary dispersion effect. After entering the cylinder 9, it first contacts the loading round block 18. The loading round block 18 is installed on the cover plate 11 through the mounting rods 17, and the nipple-shaped cylinder 21 at the top of the loading round block 18 is designed like a miniature "speed bump", which can effectively slow down the falling speed of the particles. This design not only avoids the particles from breaking due to direct impact but also enables the particles to be gradually dispersed during the sliding process. At the same time, the arc-shaped groove 20 at the connection between the nipple-shaped cylinder 21 and the loading round block 18 provides a buffer area for the particles, further reducing the impact force and the risk of breakage of the particles. When the particles continue to slide along the arc-shaped ramp at the edge of the loading round block 18, they will contact the mounting strips 14. The mounting strips 14 are made of soft rubber material and have good elasticity and wear resistance. Driven by the servo motor 19, the mounting strips 14 can generate a weak centrifugal force to help the particles disperse further. At the same time, the design of the tiny protrusions or grooves on the surface of the mounting strips 14 can generate slight friction and collision on the particles during the sliding process, thus realizing the fine adjustment of the particles.This fine-tuning effect can ensure that the particles fall onto the conveyor belt 3 at a more uniform speed and distribution. When the particles slide near the circular ring 15 on the inner wall of the cylinder 9, they will be blocked by the second circular bumps 16 on the circular ring 15. These bumps act like miniature "stumbling blocks" that can further disrupt the movement trajectories of the particles. This disruption not only promotes the uniform distribution of the particles but also causes more collisions and frictions among the particles during the sliding process, thereby enhancing the dispersion effect. Finally, the particles fall onto the conveyor belt 3 through the slope on the bottom plate 22 at the bottom of the cylinder 9. The design of the slope of the bottom plate 22 enables the particles to flow out of the cylinder 9 smoothly without causing accumulation or blockage. At the same time, the inclination angle and length of the slope are also carefully calculated to ensure that the particles can continue to disperse during the sliding process. This design not only improves the dispersion efficiency of the particles but also ensures that the particles are distributed in a uniform manner on the conveyor belt 3. In summary, through the synergistic effect of physical structures such as the guidance of the feed inlet 12, the deceleration and buffering of the loading round block 18, the rotation and fine-tuning of the mounting strip 14, the blocking and disruption of the circular ring 15 and the second circular bumps 16, and the smooth outflow of the slope provided on the bottom plate 22, the dispersion device realizes the efficient and uniform dispersion of polymer material particles. This dispersion method not only improves the efficiency and quality of material processing but also reduces the production cost and maintenance difficulty.
