[0002] Plastic granulator is a kind of equipment that makes plastic raw materials into plastic particles. At present, the market basically adopts the motor hot extrusion method to make plastic granules, that is, the plastic raw materials are added into the horizontal barrel, and the barrel melts the plastic raw materials at high temperature through high-power electric heating on the surface. Then there is a long screw in the barrel to feed the material and extrude the melted plastic from the die head into thin strips, which are then cooled by water and cut into plastic particles by blades.

[0003] However, when the traditional plastic granulator extrusion die extrude and cut the plastic into plastic particles, dust and debris may be generated on the surface of the plastic particles. When the plastic particles with dust attached fall into the collection box, the dust on the surface of the plastic particles may float into the air. In addition, a large amount of plastic chips and dust may affect the health of workshop personnel. Therefore, the utility model proposes a dust collection device for a plastic granulator to solve the above-mentioned technical problems. Utility Model Content

[0023] When using the plastic granulator to make plastic particles, the extruded plastic particles can be directly dropped into the dust removal pipe 7, and then the drive motor 10 and the dust suction pump 11 can be started. When the drive motor 10 drives the stirring plate 9 to rotate, the plastic particles are stirred to make the dust on the surface of the plastic particles fall off, and then the suction force of the dust suction pump 11 can be used to suck the stirred dust on the surface of the plastic particles out of the dust removal pipe 7 for centralized treatment, which is more convenient.

[0024] Embodiment 2

[0025] On the basis of the first embodiment, in order to facilitate dust removal on the surface of the plastic particles, a dust removal pipe 7 is provided, a positioning ring 6 is fixedly connected to the surface of the dust removal pipe 7, a discharge port 14 is opened on the side of the dust removal pipe 7, a material guide frame 15 is provided at the bottom of the dust removal pipe 7, a filter plate 16 is provided in the material guide frame 15, an air suction end of the dust suction pump 11 is provided on a hose 17, one end of the hose 17 is connected to the bottom of the material guide frame 15, a support frame plate 18 is provided in the dust removal pipe 7, a driving motor 10 is fixedly connected to the surface of the supporting frame plate 18, a driving end of the driving motor 10 is fixedly connected to the surface of the rotating shaft 8, a stirring plate 9 is fixedly connected to the surface of the rotating shaft 8, a scraper 19 is provided at one end of the stirring plate 9, a protective cover 20 is provided on the surface of the supporting frame plate 18, and the protective cover 20 can cover the driving motor 10;

[0026] When in use, the plastic particles are first allowed to fall into the dust removal pipe 7, and then the drive motor 10 and the dust suction pump 11 can be started. The drive motor 10 can be used to drive the rotating shaft 8 to rotate, so that the rotation of the stirring plate 9 can be used to stir and turn the plastic particles in the dust removal pipe 7. The scraper 19 is set to prevent a large amount of plastic particles from adhering to the inner surface of the dust removal pipe 7. Then, the dust suction pump 11 is used to make the material guide frame 15 generate a suction force, so that the dust floating due to stirring or the dust detached from the plastic particles can be sucked into the material guide frame 15. The filter plate 16 is set to prevent plastic particles from falling into the material guide frame 15.

[0027] Embodiment 3

[0028] On the basis of the second embodiment, in order to facilitate the removal of the plastic particles after dust removal, an electric push rod 3 is provided, the support frame 2 and the electric push rod 3 are fixedly connected to the surface of the support base 1, the bottom plate 5 can rotate around the support shaft 4, and the bottom plate 5 is provided with two groups, and the two groups of bottom plates 5 are symmetrically distributed about the positioning ring 6. A rotating rod 12 is provided on the side of one group of bottom plates 5, and a lifting frame 13 is sleeved on the surface of the rotating rod 12. The bottom of the lifting frame 13 is fixedly connected to the lifting end of the electric push rod 3, and the lifting frame 13 can rotate around the rotating rod 12;

[0029] When the plastic particles need to be removed during use, the discharge port 14 can be opened first, and then the electric push rod 3 can be started to move the lifting frame 13 upward. Because the lifting frame 13 can rotate around the rotating rod 12, the dust removal pipe 7 can be tilted in coordination with the support frame 2, so that the plastic particles in the dust removal pipe 7 can be poured out from the discharge port 14 more conveniently.

[0030] In actual use, when a plastic granulator is used to manufacture plastic granules, the extruded plastic granules can be directly dropped into the dust removal pipe 7, and then the drive motor 10 and the dust suction pump 11 can be started. When the drive motor 10 drives the stirring plate 9 to rotate, the plastic granules are stirred to make the dust on the surface of the plastic granules fall off, and then the suction force of the dust suction pump 11 can be used to suck the stirred dust on the surface of the plastic granules out of the dust removal pipe 7 for centralized treatment, which is more convenient. This avoids the problem that dust debris may be generated on the surface of the plastic granules when the traditional plastic granulator extrusion die extrudes and cuts the plastic into plastic granules. When the plastic granules with dust attached fall into the collection box, the dust on the surface of the plastic granules may float into the air. In addition, a large amount of plastic chips and dust may affect the health of workshop personnel.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
