Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a mixing mechanism for a pellet extruder. Background Technology

[0002] Plastic extruders (main machines) can be matched with various auxiliary plastic molding machines, such as those for pipes, films, rods, monofilaments, flat filaments, strapping, extruded mesh, sheets, profiles, granulation, and cable sheathing, to form various plastic extrusion molding production lines for producing a wide range of plastic products. Therefore, plastic extrusion molding machinery remains one of the most widely used types of machinery in the plastics processing industry, both now and in the future.

[0003] If extruder materials need to be mixed, users mostly use manual mixing to achieve the purpose. However, the materials are not mixed thoroughly, and manual mixing is inefficient. Therefore, mixing mechanisms for extruders have appeared on the market. However, existing mixing mechanisms can only stir the materials in one direction, resulting in poor material mixing effect and still low material mixing efficiency. Utility Model Content

Then, the transmission structure drives the second stirring structure to rotate, which mixes the materials longitudinally, making the materials more thoroughly mixed. During the material mixing process, the sealing structure rotates with the rotation of the first stirring structure, so that the mixed materials can be discharged from the discharge port in batches, avoiding the accumulation of materials inside the extruder.

[0009] Preferably, a bracket is mounted on the outer surface of the first housing, and a control panel is provided on one side of the second housing.

[0010] By adopting the above technical solution, the control panel and the motor are electrically connected, allowing the user to operate the motor through the control panel and fix the mixing mechanism on the extruder through the bracket.

[0013] Preferably, the sealing structure is conical, and arc-shaped baffles are provided on both sides of the top of the sealing structure.

[0014] By adopting the above technical solution, the cone-shaped sealing structure can guide the material, while the arc-shaped baffle on the sealing structure can allow the material to be discharged from the outlet in stages.

The bottom end of the outer surface of the first stirring structure is provided with the second conical tooth, and the end of the second stirring structure near the first stirring structure is provided with the first conical tooth. The first and second conical teeth are provided with a protective cover.

The first stirring structure 8 and the second stirring structure 10 are connected by a transmission structure. The user adds material into the first housing 2 and the second housing 4 through the feed port 6, and then starts the motor 7 through the control panel 5. The output end of the motor 7 drives the first stirring structure 8 to rotate, performing transverse mixing of the material. Then, the transmission structure drives the second stirring structure 10 to rotate, performing longitudinal mixing of the material, making the material more thoroughly mixed. During the mixing process, the sealing structure 9 rotates with the rotation of the first stirring structure 8, allowing the mixed material to be discharged from the discharge port 3 in stages, preventing material from accumulating inside the extruder.

[0029] In this embodiment, a bracket 1 is installed on the outer surface of the first housing 2, and a control panel 5 is provided on one side of the second housing 4. The control panel 5 is electrically connected to the motor 7. The user can operate the motor 7 through the control panel 5, and the user can fix the mixing mechanism on the extruder through the bracket 1.

[0030] In this embodiment, the output end of the motor 7 passes through the bottom of the first housing 2 and is connected to the first stirring structure 8. The top of the first stirring structure 8 is rotatably connected to the top of the interior of the second housing 4. The first stirring structure 8 can be stably placed inside the first housing 2 and the second housing 4, avoiding shaking when the first stirring structure 8 rotates.

[0031] In this embodiment, the sealing structure 9 is conical, and arc-shaped baffles are provided on both sides of the top of the sealing structure 9. The conical shape of the sealing structure 9 can guide the material, while the arc-shaped baffles on the sealing structure 9 can allow the material to be discharged from the discharge port 3 in stages.

[0032] In this embodiment, the outer surface of the second stirring structure 10 is provided with multiple stirring blades, and the two sides and two ends of the inner surface of the second housing 4 are provided with connecting structures. The second housing 4 is rotatably connected to the second stirring structure 10 through the connecting structures. The multiple stirring blades on the second stirring structure 10 can mix the materials longitudinally, while the connecting structures enable the second stirring structure 10 to be stably and firmly installed inside the second housing 4.

[0033] In this embodiment, the transmission structure between the first stirring structure 8 and the second stirring structure 10 includes a first bevel tooth 11, a second bevel tooth 12 and a protective cover 13. The bottom end of the outer surface of the first stirring structure 8 is provided with the second bevel tooth 12, and the end of the second stirring structure 10 near the first stirring structure 8 is provided with the first bevel tooth 11. The first bevel tooth 11 and the second bevel tooth 12 are provided with a protective cover 13.

[0035] In this embodiment, the first conical tooth 11 and the second conical tooth 12 mesh with each other, the discharge port 3 is connected to the first housing 2, and the feed port 6 is connected to the second housing 4. The first stirring structure 8 rotates, driving the second conical tooth 12 to rotate, and the second conical tooth 12 can drive the first conical tooth 11 to rotate, so that the second stirring structure 10 can rotate with the first conical tooth 11. While the first stirring structure 8 stirs the material laterally, the second stirring structure 10 can stir the material longitudinally. The protective cover 13 can prevent the material from contacting the first conical tooth 11 and the second conical tooth 12, and avoid damage to the meshing relationship between the first conical tooth 11 and the second conical tooth 12.

[0036] Working principle: The user starts the motor 7 through the control panel 5, which drives the first stirring structure 8 to rotate. The second conical tooth 12 can rotate with the first stirring structure 8. Since the first conical tooth 11 and the second conical tooth 12 mesh, the first conical tooth 11 can rotate with the second conical tooth 12. Since the first conical tooth 11 is connected to the second stirring structure 10, the first conical tooth 11 can drive the second stirring structure 10 to rotate. Then, the user puts the material to be mixed into the first shell 2 and the second shell 4 through the feed port 6. The material can be stirred laterally by the first stirring structure 8, and the material can be stirred longitudinally by the second stirring structure 10, so that the material can be fully mixed. Since the sealing structure 9 is connected to the first stirring structure 8, the mixed material can be discharged from the discharge port 3 in batches through the sealing structure 9, avoiding the accumulation of material inside the extruder.
