[0028] like Figure 1-3 As shown, an embodiment of the present invention provides a nylon plastic pellet processing and crushing device, comprising a frame 1, on which a crushing device and a screening device are fixedly mounted;

[0029] The mincing device includes a chassis 2 fixed to a frame 1, a feed hopper 3 connected to the top of the chassis 2, a transmission box 4 fixedly mounted on one side of the chassis 2, one end of the transmission box 4 fixedly connected to a servo motor 5, an output end of the servo motor 5 fixedly connected to a transmission gear 6 inside the transmission box 4, the transmission gear 6 meshes with a driven gear 7, and a crushing roller shaft 8 is fixedly connected at the center of the transmission gear 6 and the driven gear 7;

[0030] The screening device is installed below the discharge port at the bottom of the mincing device chassis 2. The screening device includes a support leg 9 fixed to the frame 1. The support leg 9 is provided with a spring column 10. A material plate 12 is installed on the support leg 9. A vibration motor 11 is fixed to the support leg 9 below the material plate 12. The material plate 12 is provided with a grid leakage hole 13.

[0031] 1. Mincing device

[0032] Chassis 2: Fixed to frame 1, providing installation space and protection for the mincing components.

[0033] Feed hopper 3: Funnel-shaped, convenient for pouring nylon plastic pellets into the equipment.

[0034] Transmission box 4: fixed on one side of the chassis 2, with the transmission gear 6 and the driven gear 7 installed inside.

[0035] Servo motor 5: provides power for the mincing device.

[0036] Transmission gear 6: connected to the output end of the servo motor 5 and meshing with the transmission driven gear 7.

[0037] Driven gear 7: cooperates with transmission gear 6 to drive the crushing roller shaft 8 to rotate.

[0038] Crushing roller 8: moves in opposite directions and is provided with cross cutting blades to crush the nylon plastic particles.

[0039] 2. Screening device

[0040] Support legs 9: fixed to the frame 1, supporting the entire screening device, with spring columns 10 inside.

[0041] Spring column 10: plays the role of shock absorption and increasing screening effect.

[0042] Vibration motor 11: fixed on the support leg 9, located below the material plate 12, providing power for screening.

[0043] The material plate 12 is arranged to be tilted downward, and is provided with a grid hole 13 for screening nylon plastic particles.

[0044] Grille leakage hole 13: The aperture size can be adjusted according to actual needs.

[0045] 3. Auxiliary structure

[0046] Conveyor belt 14: located on the frame 1 below the material plate 12, used to transport the screened nylon plastic pellets.

[0047] Working principle:

[0048] Nylon plastic pellets first enter chassis 2 through a funnel-shaped feed hopper 3. A servo motor 5 on one side of chassis 2 is activated, driving drive gear 6. Drive gear 6 engages with driven gear 7, causing a grinding roller 8 at the center of drive gear 6 and driven gear 7 to move in opposite directions. The cross-cutting blades on grinding roller 8 grind the nylon plastic pellets entering chassis 2.

[0049] The shredded nylon plastic pellets fall from the outlet at the bottom of the chassis 2 onto the screening device's feed plate 12. The vibration motor 11 on the legs 9 is activated, and the elastic action of the spring column 10 causes the feed plate 12 to vibrate. Smaller particles of nylon plastic pellets fall through the grating holes 13 on the feed plate 12, while larger particles continue to slide forward due to the tilt of the feed plate 12, waiting to be re-entered into the mincing device for crushing.

[0050] The qualified nylon plastic pellets falling from the grid leak holes 13 fall onto the conveyor belt 14 below and are transported by the conveyor belt 14 to a designated location for subsequent processing.

[0051] like Figure 1 As shown, in some embodiments, the feed hopper 3 is funnel-shaped; the funnel-shaped design makes the feed opening larger, and the nylon plastic pellets can be poured into the equipment more conveniently, reducing the difficulty and time of feeding and improving work efficiency.

[0052] like Figure 2As shown, in some embodiments, the crushing rollers 8 move in opposite directions, and the crushing rollers 8 are provided with cross cutting blades; improving the crushing efficiency: the two crushing rollers 8 move in opposite directions, so that the nylon plastic particles are subjected to bidirectional extrusion and shear forces between the two, and can be crushed into smaller particles more quickly, greatly improving the crushing efficiency.

[0053] like Figure 1 As shown, in some embodiments, the material plate 12 is arranged to be tilted downward; the tilted downward material plate 12 allows the nylon plastic particles falling thereon to slide naturally downward under the action of gravity, and the material can be transported without additional power, thereby improving the screening efficiency.

[0054] like Figure 1 As shown, in some embodiments, a conveyor belt 14 is provided on the frame 1 below the material plate 12; the conveyor belt 14 can promptly transport the qualified nylon plastic pellets screened from the material plate 12 to the next processing link or a designated storage location, thereby avoiding the accumulation of materials at the bottom of the equipment and ensuring the continuity of production.

[0055] like Figure 3 As shown, in some embodiments, the aperture size of the grille leakage hole 13 is adjusted according to actual needs; the aperture size of the grille leakage hole 13 can be adjusted according to different nylon plastic pellet processing requirements to obtain crushed materials of different particle sizes.

[0056] like Figure 2 As shown, in some embodiments, the inner wall of the chassis 2 is consistent with the inclined shape of the feed hopper 3; when the inclined shape of the feed hopper 3 is consistent with the inner wall of the chassis 2, the nylon plastic pellets will not encounter obvious obstacles or corners when entering the chassis 2 from the feed hopper 3, and can slide more smoothly into the grinding device for crushing, reducing the risk of material accumulation and blockage in the transition area.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
