Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1-7 , the present invention provides a technical solution: a plastic particle screening and impurity removal device, including an impurity removal box 10, a material guiding hopper 20 is arranged inside the impurity removal box 10, and a conical filter cylinder 40 is rotatably installed at the inner bottom of the impurity removal box 10; the plastic particles to be screened are conveyed into the conical filter cylinder 40 through the material guiding hopper 20, and then the plastic particles are screened and filtered through the conical filter cylinder 40 to screen out the debris in the plastic particles.

[0019] A feed pipe 41 is arranged at the center of the top of the conical filter cylinder 40, the top of the feed pipe 41 is rotatably installed at the center of the bottom of the material guiding hopper 20, a discharge pipe 42 penetrating through the bottom of the impurity removal box 10 is arranged at the center of the bottom of the conical filter cylinder 40, and chip discharging holes 43 are uniformly formed on the surface of the conical filter cylinder 40; the plastic particles to be screened enter the feed pipe 41 through the material guiding hopper 20, and then are conveyed into the conical filter cylinder 40 through the feed pipe 41. At the same time, the conical filter cylinder 40 rotates, so that the plastic particles in the conical filter cylinder 40 move in a centrifugal motion, and the debris doped in the plastic particles is screened out. The screened debris is discharged from the chip discharging holes 43, and the screened plastic particles are discharged from the discharge pipe 42.

[0020] Furthermore, the aperture of the chip discharging hole 43 is smaller than the cross-sectional dimension of the plastic particles. When the conical filter cylinder 40 rotates, the plastic particles passing through the conical filter cylinder 40 move in a centrifugal motion, and then the debris doped in the plastic particles will be separated from the plastic particles, and the separated debris will be discharged from the chip discharging holes 43. The screened plastic particles rotate and fall downward along the conical filter cylinder 40 and are discharged from the discharge pipe 42, realizing the purpose of screening and impurity removal of the plastic particles.

[0021] Among them, a collar 50 is provided at the position corresponding to the discharge pipe 42 at the inner bottom of the impurity removal box 10. The discharge pipe 42 penetrates through the center of the collar 50. A gear ring 44 is sleeved on one side of the surface of the discharge pipe 42 located inside the collar 50. An extension shell 51 is provided on one side of the surface of the collar 50. A servo motor 52 is provided inside the extension shell 51. A driving gear 53 meshing with the gear ring 44 is provided at the output end of the servo motor 52. When it is necessary to drive the conical filter cylinder 40 to rotate, the servo motor 52 is started, and then the servo motor 52 drives the driving gear 53 to rotate. Through the cooperation of the driving gear 53 and the gear ring 44, the discharge pipe 42 is driven to rotate, so as to drive the conical filter cylinder 40 to rotate synchronously. In this way, when the plastic particles enter the conical filter cylinder 40, the plastic particles passing through the conical filter cylinder 40 perform a centrifugal motion, and then the debris doped in the plastic particles will be separated from the plastic particles, and the separated debris will be discharged from the chip discharge hole 43. The screened plastic particles rotate and fall downward along the conical filter cylinder 40 and are discharged from the discharge pipe 42, achieving the purpose of screening and removing impurities from the plastic particles.

[0022] Among them, a hollow opening is provided at the position of the surface of the collar 50 corresponding to the extension shell 51. The edge of the driving gear 53 extends into the collar 50 through the hollow opening. The hollow opening is provided at the position of the surface of the collar 50 corresponding to the driving gear 53 to facilitate one side of the driving gear 53 to extend into the collar 50 and ensure that the driving gear 53 can mesh with the gear ring 44 on the surface of the collar 50.

[0023] Specifically, the servo motor 52 is powered by an external power supply. When the servo motor 52 works, the servo motor 52 can drive the driving gear 53 to rotate. Since the driving gear 53 meshes with the gear ring 44, the driving gear 53 can drive the gear ring 44 to rotate, so as to drive the discharge pipe 42 to rotate synchronously, achieving the purpose of driving the conical filter cylinder 40 to rotate.

[0024] Among them, the conical filter cylinder 40 is an inverted conical structure, and the inside of the conical filter cylinder 40 is hollow. When it is necessary to screen and filter the plastic particles, the plastic particles to be screened are conveyed into the conical filter cylinder 40 through the feed pipe 41, and at the same time, the conical filter cylinder 40 is driven to rotate. Then the plastic particles passing through the conical filter cylinder 40 perform a centrifugal motion, and then the debris doped in the plastic particles will be separated from the plastic particles, and the separated debris will be discharged from the chip discharge hole 43. The screened plastic particles rotate and fall downward along the conical filter cylinder 40 and are discharged from the discharge pipe 42, achieving the purpose of screening and removing impurities from the plastic particles.

[0025] Among them, the servo motor 52 drives the conical filter cylinder 40 to rotate through the cooperation of the driving gear 53 and the gear ring 44. During the rotation of the conical filter cylinder 40, the plastic particles perform a centrifugal motion, and the debris in the plastic particles is discharged through the chip discharge hole 43.

[0026] Among them, a partition plate 11 is provided above the interior of the impurity removal box 10. Three material guiding cylinders 12 are equidistantly arranged on the partition plate 11. A feed pipe 13 is inserted at a position corresponding to the material guiding cylinder 12 at the top of the impurity removal box 10. The bottom of the feed pipe 13 extends into the material guiding cylinder 12. The plastic particles to be screened are added into the impurity removal box 10 through the feed pipe 13, and the plastic particles fall into the material guiding cylinder 12. Then, the plastic particles passing through the material guiding cylinder 12 fall into the material guiding hopper 20. Next, the plastic particles in the material guiding hopper 20 enter the conical filter cylinder 40 through the feed pipe 41, and the plastic particles are screened and filtered by the conical filter cylinder 40.

[0027] Among them, an air pump 14 is provided on one side of the outer surface of the impurity removal box 10 corresponding to the partition plate 11. An air blowing pipe 15 is provided at the output end of the air pump 14. Three branch air pipes 16 corresponding to the material guiding cylinders 12 are respectively provided on the air blowing pipe 15. The branch air pipes 16 extend into the material guiding cylinders 16. Air outlet holes 17 are evenly formed on the surface of the branch air pipes 16. In order to disperse the plastic particles to be screened, gas is generated by the air pump 14, and then the air pump 14 enters and exits the gas into the material guiding cylinder 12 through the air blowing pipe 15 and the branch air pipes 16, forming a dispersed air flow in the material guiding cylinder 12. When the plastic particles fall into the material guiding cylinder 12, the dispersed air flow blows the plastic particles apart, preventing the plastic particles from adhering together and facilitating subsequent screening and impurity removal.

[0028] Among them, the air blowing pipe 15 is arranged parallel to the partition plate 11, and the air blowing pipe 15 is located above the partition plate 11; the material guiding cylinder 12 is a cylindrical structure with openings at both ends, the material guiding cylinder 12 is arranged perpendicular to the partition plate 11, and the branch air pipe 16 is arranged parallel to the material guiding pipe 12.

[0029] Specifically, when screening and removing impurities from plastic particles, first add the plastic particles into the impurity removal box 10 through the feed pipe 13, and make the plastic particles fall into the material guiding cylinder 12. At the same time, turn on the air pump 14. Gas is generated by the air pump 14, and then the air pump 14 enters and exits the gas into the material guiding cylinder 12 through the air blowing pipe 15 and the branch air pipes 16, forming a dispersed air flow in the material guiding cylinder 12. When the plastic particles fall into the material guiding cylinder 12, the dispersed air flow blows the plastic particles apart, preventing the plastic particles from adhering together and facilitating subsequent screening and impurity removal.

[0030] Among them, a box door 30 is rotatably installed at a position corresponding to the conical filter cylinder 40 on the front of the impurity removal box 10. When the plastic particles are screened and removed impurities through the conical filter cylinder 40, the debris in the plastic particles enters the bottom inside the impurity removal box 10 through the chip discharge hole 43 under the action of centrifugal force. In order to facilitate the cleaning of the filtered debris, an openable box door 30 is installed at the bottom of the front of the impurity removal box 10, facilitating subsequent cleaning of the debris.

[0031] Among them, support legs are provided at the four corners of the bottom of the impurity removal box 10, which are not shown in the drawings. The impurity removal box 10 is supported by the support legs, so that the bottom of the impurity removal box 10 is separated from the ground, facilitating the discharge of the discharge pipe 42.

[0032] Working principle: First, plastic particles are added into the impurity removal box 10 through the feed pipe 13, and the plastic particles fall into the guide cylinder 12. At the same time, the air pump 14 is turned on. The air pump 14 generates gas, and then the air pump 14 enters and exits the gas into the guide cylinder 12 through the air blowing pipe 15 and the air distribution pipe 16, forming a dispersed air flow in the guide cylinder 12. When the plastic particles fall into the guide cylinder 12, the dispersed air flow blows the plastic particles apart to prevent the plastic particles from adhering together. Then the plastic particles fall into the guide hopper 20 and are transported to the conical filter cylinder 40 through the feed pipe 41. At the same time, the servo motor 52 is turned on, and then the servo motor 52 drives the driving gear 53 to rotate. Through the cooperation of the driving gear 53 and the gear ring 44, the discharge pipe 42 is driven to rotate, thereby driving the conical filter cylinder 40 to rotate synchronously. In this way, when the plastic particles enter the inside of the conical filter cylinder 40, the plastic particles passing through the conical filter cylinder 40 perform a centrifugal motion, and then the debris mixed in the plastic particles will be separated from the plastic particles, and the separated debris will be discharged from the chip discharge hole 43. The screened plastic particles rotate and fall downward along the conical filter cylinder 40 and are discharged from the discharge pipe 42, achieving the purpose of screening and removing impurities from the plastic particles.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
