The modified nylon plastic pelletizing and screening device is powered by the power mechanism to drive the cutting wheel to work, and the nylon plastic is processed. The processed nylon particles fall into the interior of the first sieve block. At this time, the first sieve block is rotated by the power mechanism to perform preliminary filtration of the particles. The filtered particles fall to the surface of the filter sieve plate for secondary filtration. The larger particles on the surface of the filter sieve plate are taken out by opening the movable door, and the blocking block is rotated. At this time, the blocking block moves upward, so that the large particles are discharged from the first sieve block.

Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Combined with reference Figure 1-Figure 4 The utility model provides a nylon plastic pelletizing, screening and transmission mechanism, including a conveyor belt 1 for separating and transmitting nylon plastic particles. In the present application, the conveyor belt 1 can be divided into two transmission paths by a partition. A screening plate 2 is obliquely arranged above the conveyor belt 1. The screening plate 2 is provided with sieve holes to allow small nylon plastic particles to pass through, thereby achieving a secondary screening effect. A first cover plate 3 and a second cover plate 4 are fixedly connected on both sides of the screening plate 2, respectively. A screening area is formed between the first cover plate 3 and the screening plate 2, and a collecting area is formed between the second cover plate 4 and the screening plate 2. A first discharge port 31 is provided on the first cover plate 3, and a second discharge port 41 is provided on the second cover plate 4. In the present application, the positions of the screening plate 2, the first cover plate 3 and the second cover plate 4 can be installed on the mounting surface near the conveyor belt 1 through a support.

[0024] The first discharge port 31 is fixedly connected to a first discharge pipe 11, and the second discharge port 41 is fixedly connected to a second discharge pipe 12. Both the first discharge pipe 11 and the second discharge pipe 12 extend to the transmission surface of the conveyor belt 1. The first discharge pipe 11 can be used to directly discharge large nylon plastic particles so as to be transferred to the conveyor belt 1 for transmission, and the second discharge pipe 12 can be used to directly discharge small nylon plastic particles so as to be transferred to the conveyor belt 1 for transmission.

[0025] A rotating drum 5 is rotatably connected to the screening plate 2 and the first cover plate 3, a rotating motor 51 for driving the rotating drum 5 to rotate is fixedly connected to the first cover plate 3, a plurality of rotating plates 6 are fixedly connected to the outer surface of the rotating drum 5, the rotating plates 6 are located in the sub-screening area, and the rotating plates 6 can drive the nylon plastic particles fed into the sub-screening area so as to be graded and screened through the screening plate 2, a barrel 7 is fixedly passed through the first cover plate 3, a pelletizing structure 8 is provided on the barrel 7, a plurality of stirring components 9 are provided on the rotating drum 5, each stirring component 9 is located between two adjacent rotating plates 6, and a driving structure 10 for driving the stirring component 9 to rotate is provided in the rotating drum 5.

[0026] The pelletizing structure 8 includes a pair of pelletizing rollers 81 rotatably connected to the barrel 7, a pelletizing motor 82 fixedly connected to the side of the barrel 7 and driving one of the pelletizing rollers 81 to rotate, and a first gear 83 fixedly connected to the axial end of each pelletizing roller 81. The pair of first gears 83 are meshed and connected with each other.

[0027] Specifically, by feeding nylon plastic pellets into the barrel 7 and starting the pelletizing motor 82, a pair of pelletizing rollers 81 can rotate relatively under the action of the mutual meshing of the first gear 83, so that the nylon plastic pellets can be pelletized, and the pelletized plastic particles can fall into the screening area. By starting the rotating motor 51, it can drive several rotating plates 6 on the rotating drum 5 to rotate, and two adjacent rotating plates 6 can carry the plastic particles to move. Under the setting of the inclination angle of the screening plate 2, the plastic particles can be screened through the screening plate 2 under the action of gravity and thrust. The small nylon plastic particles can enter the collection area through the screening plate 2 and be discharged through the second discharge port 41, while the unscreened small nylon plastic particles can continue to be pushed by the rotating plate 6 until the rotating plate 6 rotates to the eight o'clock position, and the small nylon plastic particles can be discharged through the first discharge port 31. In this way, the pelletizing, screening and transmission of the nylon plastic particles are continuous, thereby improving the processing efficiency of nylon plastic.

[0028] The first discharge port 31 is located at the eight o'clock direction. The advantage of such a design is that when the rotating plate 6 rotates to the eight o'clock direction, the tilting angle of the rotating plate 6 can facilitate the large nylon plastic particles pushed by it to be discharged through the first discharge port 31 .

[0029] Each stirring assembly 9 includes a shaft 91 rotatably connected to the drum 5 and a plurality of stirring rods 92 fixedly connected to the shaft 91 .

One end of the fixing frame 101 extends into the rotating drum 5. The second gear 103 is located in the rotating drum 5 and is meshed with the annular rack 102 for transmission connection.

[0031] Specifically, when the rotating plate 6 pushes the nylon plastic particles for screening, the rotation of the drum 5 can cause the second gear 103 to revolve on the path of the annular rack 102, thereby providing a rotational force for the shaft 91, so that the shaft 91 can drive the stirring rod 92 thereon to stir the nylon plastic particles between the two adjacent rotating plates 6, thereby improving the passability of the nylon plastic particles on the screening plate 2, thereby promoting the screening of the nylon plastic particles and ensuring the thoroughness of the two-stage screening.
