Technical Field
[0001] This utility model relates to the field of plastic production technology, and in particular to a plastic particle masterbatch addition device. Background Technology
[0002] In the plastics processing industry, to impart specific colors and properties to plastic products, it is typically necessary to mix color masterbatches with plastic particles. Color masterbatches are concentrated products made from pigments, carrier resins, and additives. The uniform mixing of color masterbatches with plastic particles is a crucial step in ensuring the color consistency and quality stability of plastic products. Currently, the common method for mixing plastic particles with color masterbatches is to directly add the color masterbatch to the plastic particle mixing tank and stir.
[0003] However, existing additive equipment has certain defects in actual use. After the color masterbatch is added, local accumulation is likely to occur. Relying solely on the conventional stirring of the stirring device, it is difficult to evenly disperse the color masterbatch in the plastic particles in a short time, resulting in a long mixing time. This not only reduces production efficiency but may also cause problems such as color deviation and unstable performance of plastic products due to uneven mixing, failing to meet the production requirements of high-quality plastic products. Therefore, this utility model proposes a new solution. Utility Model Content

[0033] Please see Figure 1-7 This utility model provides a technical solution: a plastic particle masterbatch adding device, including a plastic mixing tank 1 and a masterbatch adding component. The masterbatch adding component is disposed inside the plastic mixing tank 1 and includes two masterbatch tanks 4, which are fixedly connected to the upper end of the plastic mixing tank 1. A plastic guide plate 12 is fixedly connected inside the plastic mixing tank 1. The plastic guide plate 12 is a frustum-shaped shell, and a plastic dispersion plate 13 is rotatably connected to the surface of the plastic guide plate 12. The surface of the plastic dispersion plate 13 is fixedly connected to the plastic dispersion plate 13. Multiple dispersing strips 18 are fixedly connected. Multiple first guide grooves 19 are opened on the surface of the plastic guide plate 12. Multiple second guide grooves 20 are opened on the side of the plastic dispersing plate 13. A second drive motor 6 is fixedly connected to the upper end of the plastic mixing tank 1. A second rotating shaft 16 is fixedly connected to the output end of the second drive motor 6. The second rotating shaft 16 is rotatably connected to the plastic mixing tank 1. A gear 17 is fixedly connected to the surface of the second rotating shaft 16. The plastic dispersing plate 13 is annular. The inner side of the plastic dispersing plate 13 is provided with tooth grooves that mesh with the gear 17.
[0034] The color masterbatch addition assembly also includes a plastic guide plate 14, which is disposed inside the plastic mixing tank 1. Multiple guide plate connecting rods 15 are fixedly connected to the upper end of the plastic guide plate 14, and the upper ends of the multiple guide plate connecting rods 15 are fixedly connected to the plastic mixing tank 1. The plastic dispersion disc 13 is rotatably connected to the plastic guide plate 14, and the second rotating shaft 16 is rotatably connected to the plastic guide plate 14. The upper end of the plastic guide plate 14 is a cone shape with an upward convex shape.
[0035] A first drive motor 5 is fixedly connected to the upper end of the plastic mixing tank 1. A first rotating shaft 7 is fixedly connected to the output end of the first drive motor 5. The first rotating shaft 7 rotates through the plastic guide plate 14 and the plastic guide plate 12. Two spiral stirring blades 22 are fixedly connected to the surface of the first rotating shaft 7. Both spiral stirring blades 22 are spiral-shaped with one end larger than the other.
[0036] A stirring blade 8 is fixedly connected to the surface of the first rotating shaft 7. A through groove 9 is opened on the surface of the stirring blade 8. A first reinforcing rib 10 and a second reinforcing rib 11 are fixedly connected to the surface of the stirring blade 8. The stirring blade 8, the through groove 9, the first reinforcing rib 10 and the second reinforcing rib 11 are all arranged in three sets in a ring array on the surface of the first rotating shaft 7.
[0037] Three connecting rods 21 are fixedly connected to the side of the plastic dispersion disc 13.
[0038] A feed pipe 2 is fixedly connected to the upper end of the plastic mixing tank 1.
[0039] A discharge pipe 3 is fixedly connected to the lower end of the plastic mixing tank 1.
[0040] When using this device, different colored masterbatches are loaded into the two masterbatch cans 4 at the top of the plastic mixing tank 1, and the feeding amount is controlled by the can opening to make the masterbatches fall into the plastic mixing tank 1.
[0041] Start the second drive motor 6, and the second shaft 16 at its output end drives the gear 17 to rotate; since the inner tooth groove of the plastic dispersion disk 13 meshes with the gear 17, the plastic dispersion disk 13 begins to rotate around the surface of the plastic guide disk 12.
[0042] During rotation, the dispersion strips 18 on the surface of the plastic dispersion disk 13 exert a mechanical pushing effect on the masterbatch that falls onto its surface. At the same time, the second guide groove 20 on the side and the first guide groove 19 on the surface of the plastic guide disk 12 form an interlaced guide channel, which allows the masterbatch to diffuse in all directions under centrifugal force and guide action, avoiding local accumulation.
[0043] The upper end of the plastic guide plate 14 is a cone shape with an upward convex shape, and it is fixed to the top of the mixing tank by the guide plate connecting rod 15. When the masterbatch or plastic particles fall into the area of the plastic guide plate 14, the cone-shaped structure guides the material to slide down the slope to prevent accumulation. At the same time, the bottom of the plastic dispersion disk 13 is rotatably connected to the plastic guide plate 14. The plastic guide plate 14 provides support and limit for the plastic dispersion disk 13 to ensure its stable rotation.
[0044] The first drive motor 5 drives the first rotating shaft 7 to rotate, which in turn drives two symmetrical spiral stirring blades 22 to rotate. The spiral blades are spiral-shaped with one end larger than the other. When rotating, they generate an axial conveying force from bottom to top, which lifts the material at the bottom upward. At the same time, the outer large-diameter blades generate a stronger stirring and shearing effect on the edge material, realizing the circulation and mixing of the upper and lower layers of material.
[0045] The three sets of stirring blades 8 on the first rotating shaft 7 are arranged in a ring array. The through grooves 9 on the surface of the blades reduce stirring resistance and at the same time form local turbulence, enhancing the collision and mixing between materials. The first reinforcing rib 10 and the second reinforcing rib 11 improve the structural strength of the blades and ensure long-term stable operation.
[0046] The connecting rod 21 on the side of the plastic dispersion disk 13 rotates with the plastic dispersion disk 13. Its end is close to the surface of the plastic guide disk 12, which can scrape the masterbatch or plastic particles accumulated on the surface of the plastic guide disk 12 and make them fall back into the mixing area.
[0047] The plastic guide plate 12 is a frustum-shaped shell with a structure that is narrow at the top and wide at the bottom, guiding the material to disperse towards the edge of the mixing tank. Combined with the movement of the stirring blades, this further improves the uniformity of mixing.
[0048] Plastic particles enter the mixing tank 1 through the feed pipe 2 and are mixed with color masterbatch under the action of plastic dispersion disc 13, spiral stirring blade 22 and stirring blade 8; after mixing, the material is discharged from the lower discharge pipe 3.
[0049] The second drive motor 6 and the first drive motor 5 can have their speeds adjusted independently. The matching relationship between the speeds of the plastic dispersion disc 13, the spiral stirring blade 22, and the stirring blade 8 is controlled by an external PLC and frequency converter to ensure uniform dispersion in a short time and improve production efficiency.
[0050] Furthermore, the plastic dispersion disc 13 is linked to the second drive motor 6 via gear 17. When the dispersion strips 18 on its surface rotate, they generate a mechanical pushing force on the masterbatch. Combined with the staggered flow guiding structure of the second guide groove 20 on the side and the first guide groove 19 of the plastic guide disc 12, a dual effect of centrifugal force and flow guiding channel is formed, so that the masterbatch is forced to diffuse into the circumferential area of the mixing tank during the falling process. Compared with the traditional direct pouring method, the initial dispersion area is expanded, local accumulation is reduced from the source, and the efficiency of the device is improved.
[0051] The tapered protrusion design at the upper end of the plastic guide plate 14 uses the inclined angle to quickly guide the accumulated material to the mixing area, which can reduce the residence time of the material in the area of the plastic guide plate 14 and prevent the masterbatch from forming agglomerates due to long-term residence, thereby improving the efficiency of the device.
[0052] Structural Description: Plastic Mixing Tank 1: As the container of the whole device, it holds plastic particles and masterbatch, providing a mixing space; the upper end is connected to the feed pipe, masterbatch tank and drive motor, and the lower end is connected to the discharge pipe to realize the input and output of materials;

[0056] Plastic dispersion disc 13: When the surface dispersion strip 18 rotates, it generates a mechanical pushing force on the masterbatch, forcibly dispersing the material;
[0057] The second guide groove 20 on the side cooperates with the first guide groove 19 of the plastic guide plate to form a dual effect of centrifugal force and guide flow, thereby expanding the initial dispersion area of the masterbatch.
[0058] The inner tooth groove meshes with gear 17 and is driven to rotate by the second drive motor. The bottom is rotatably connected to plastic guide plate 14 to ensure stable rotation.
[0059] As the side connecting rod 21 rotates, it scrapes the material accumulated on the surface of the plastic guide plate, causing it to fall back into the mixing area.
[0060] Plastic guide plate 14: The conical structure guides the falling masterbatch or plastic particles to slide down the slope, preventing them from accumulating or clumping at the top;
[0061] The guide plate connecting rod 15 is fixed to the top of the mixing tank to provide support and limit the plastic dispersion disc 13;
[0062] Second drive motor 6, second rotating shaft 16, gear 17:
[0063] The second drive motor drives the second rotating shaft to rotate, and through the meshing of the gear 17 with the tooth groove of the plastic dispersion disk 13, it drives the plastic dispersion disk to rotate, thereby realizing the dispersion function of the color masterbatch.
[0064] The rotation speed can be independently adjusted via an external controller to match the stirring efficiency.
[0065] First drive motor 5, first rotating shaft 7:
[0066] The first drive motor drives the first rotating shaft to rotate, which in turn drives the spiral stirring blades and stirring blades to rotate, thereby realizing the stirring and circulating mixing of materials;
[0067] The rotation speed can be adjusted independently, and when combined with the rotation speed of the dispersing disc, it can improve mixing efficiency;
[0068] Spiral mixing blade 22: When rotating, it generates an axial conveying force from bottom to top, lifting the material at the bottom upwards and realizing the circulation of materials between the upper and lower layers;
[0069] The large-diameter blades on the outer side exert a stronger mixing and shearing effect on the edge material, enhancing the uniformity of mixing.
[0070] Stirring blade 8: Surface grooves 9 reduce stirring resistance, create local turbulence, and promote material collision and mixing;
[0071] The first reinforcing rib 10 and the second reinforcing rib 11 enhance the structural strength of the blade and ensure long-term stable operation.
[0072] Feed pipe 2: Used to feed plastic particles and mix them with color masterbatch;
[0073] Discharge pipe 3: Discharges materials after mixing is complete.
