[0002] In the processing of modified nylon masterbatch, screening devices are widely used to screen the modified nylon masterbatch. Nylon is a highly polar polymer material, in which a large number of hydrogen bonds can be formed between its molecules, thus it has a high melting point with a narrow melting range. This material exhibits excellent mechanical properties, hydrophilicity, lubricity, wear resistance, corrosion resistance, oil resistance, and barrier properties. It is non-toxic and odorless, and has good processing performance, making it widely used in various industries. Screening devices are also used in the processing of modified nylon masterbatch.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0033] Combination Figure 1This utility model discloses a screening device for modified nylon material masterbatch, comprising a shell 1, a blower 9 fixedly connected to one side of the outer wall of the shell 1, which blows air into the shell 1 when the blower 9 is working, and performs coarse screening when the masterbatch is fed in. A conveying pipe 10 is fixedly connected through and fixedly connected to the top of the blower 9. Limiting plates 27 are fixedly connected to both the front and rear sides of the inner wall of the shell 1, limiting the movement of moving rods 28 and causing them to move linearly back and forth. The moving rods 28 are slidably connected to the inner ring of the limiting plates 27. A cover 2 is provided on the top of the shell 1, and a feed hopper 3 is fixedly connected through and fixedly connected to one side of the top of the cover 2. The feed hopper 3 is used to feed materials. The top of both sides of the cover 2 is fixedly connected to a female locking block 26. The front and rear sides of the cover 2 are fixedly connected to a male locking block 25. The male locking block 25 and the female locking block 26 are locked together. After the female locking block 26 releases its limit on the male locking block 25, the cover 2 can be removed for internal maintenance. The bottom of the outer shell 1 is connected to two discharge pipes 21. The bottom of the two discharge pipes 21 is connected to a slide valve 22. When the solenoid valve 22 is opened, impurities and unqualified masterbatch can be discharged from the discharge pipes 21. The top of the moving rod 28 is fixedly connected to a second slide rail 19. The inclined plate 32 assists in allowing the masterbatch to enter the right collection box 31. The right side of the inner wall of the outer shell 1 is fixedly connected to the inclined plate 32.
[0034] Combination Figure 2 and Figure 3 The other end of the conveying pipe 10 is connected to a connecting pipe 23. A uniformly distributed nozzle 24 is connected to one side of the outer ring of the connecting pipe 23. Multiple nozzles 24 are provided to prevent areas from being missed and affecting screening. Two first connecting plates 14 are fixedly connected between the inner walls of the outer shell 1. Two support rods 15 are slidably connected to the top of each of the two first connecting plates 14. When the collecting box 31 moves under force, the support rods 15 slide on the first connecting plates 14 and compress the springs 16. When the force decreases, the springs 16 rebound. Springs 16 are fitted around the outer rings of two adjacent support rods 15. First slide rails 17 are fixedly connected to the top of two adjacent springs 16. First sliding plates 18 are slidably connected to the inner walls of the two first slide rails 17. 8. A collection box 31 is fixedly connected to the top of each of the two collection boxes 31. The inside of the two collection boxes 31 is equipped with a filter screen with different perforations, which can screen out masterbatch of different sizes. A first filter screen 12 is set at the bottom of the inner wall of the left collection box 31, and a second filter screen 13 is set at the bottom of the inner wall of the right collection box 31. Motors 11 are fixedly connected to the front and rear sides of the outer wall of the outer shell 1. When the motors 11 work, they can drive the eccentric wheel 29 to rotate, and then pull the support plate 30, which drives the moving rod 28 to move, causing the collection box 30 to shake. The output ends of the two motors 11 pass through the outer shell 1 and are fixedly connected to the eccentric wheel 29. The support plate 30 is rotatably connected to one side of the two eccentric wheels 29, and the moving rod 28 is rotatably connected to one side of the two support plates 30. A collection component is set at the center position between the inner walls of the outer shell 1.
[0035] Combination Figure 1 and Figure 4 The collection component includes a second slide rail 19, which is fixedly connected to the outer shell 1. Two second slide plates 20 are slidably connected through one side of the outer shell 1. The second slide plates 20 slide within the second slide rail 19, limiting and supporting one side of the collection box 31. The top of each of the two second slide plates 20 is fixedly connected to the collection box 31, which is used to collect the screened masterbatch for easy removal. A uniformly distributed fixing plate 4 is fixedly connected to one side of the outer wall of the outer shell 1. A transmission rod 5 is fixedly connected between two adjacent fixing plates 4. When the protective door 8 is lifted, the rotating block 7 rotates on the transmission rod 5, pulling the collection box 31 out of the outer shell 1. Two rotating blocks 7 are rotatably connected to the outer ring of the transmission rod 5. A torsion spring 6 is sleeved at the center of the outer ring of the transmission rod 5. When the force on the protective door 8 disappears, the torsion spring 6 exerts force to reset the protective door 8 for protection. A sealing gasket is provided on the protective door 8 to increase the sealing during screening. The bottom of two adjacent rotating blocks 7 is fixedly connected to the protective door 8.
[0036] Working principle: When using the screening device, firstly, the masterbatch is poured from the feed hopper 3 into the outer casing 1. At the same time, the blower 9 is started, spraying air from multiple nozzles 24 to blow the falling masterbatch. Smaller masterbatch will be blown into the left collection box 31, while larger particles will enter the right collection box 31. Then, the motor 11 is started, driving the eccentric wheel 29 to rotate. This pulls the support plate 30, causing the moving rod 28 to move up and down repeatedly under the limit of the limiting plate 27. This pulls the collection box 31 to move. When the collection box 31 moves downward, it will cause the support rod 15 to slide on the first connecting plate 14, and then squeeze the spring 16. When the collection box 31 moves downward, it will cause the support rod 15 to slide on the first connecting plate 14, and then squeeze the spring 16. 1. Move upwards, spring 16 rebounds, repeating this process to shake the collection box 31, improving the screening effect. When screening is complete and the screened masterbatch needs to be removed, open the slide valve 22 to remove the unqualified masterbatch and impurities. Then, lift the protective door 8 and pull out the corresponding collection box 31. The first slide plate 18 slides in the first slide rail 17, and the second slide plate 20 slides in the second slide rail 19, pulling the collection box 31 out of the outer shell 1 to remove the screened masterbatch. At the same time, the filter screen inside the collection box 1 can also be maintained. When the force on the protective door 8 disappears, the torsion spring 6 applies force to reset the protective door 8 for protection, making it convenient to use.
