Description

Technical Field

[0001] This utility model relates to the field of nylon filament production technology, and in particular to a cooling device for recycled nylon waste filament extrusion. Background Technology

[0002] Nylon waste filament recycling is a process involving the technology of chemical fibers. It aims to transform waste nylon filaments into reusable recycled chips through a series of technological steps. The sorted nylon waste filament mixture is fed into a melting machine for melting, transforming it into polyamide melt. This step is part of chemical recycling or pyrolysis recycling, where the waste filaments are depolymerized through a chemical reaction to directly recover caprolactam monomers. Therefore, cooling treatment is required after molding.

[0003] An existing nylon waste filament recycling and extrusion cooling device incorporates a cooling tank to cool the nylon waste filament. The device also includes a guiding mechanism and a lifting and limiting mechanism. The lifting and limiting mechanism helps to better contain the nylon waste filament within the cooling tank, while the guiding mechanism facilitates its transport. This device effectively cools the nylon waste filament. However, because cooling occurs through contact with water, a large amount of moisture remains on the surface of the nylon filament. This moisture not only increases the weight of the nylon filament, affecting the winding effect, but also drips onto the ground, impacting the operating environment. A search revealed that the technical solution provided by utility model application number CN202122676165.9 also suffers from the aforementioned problems. Utility Model Content

[0026] Reference Figure 1-4This utility model discloses a nylon waste filament recycling extrusion cooling device, which includes a cooling tank 1, a guide roller 2 inside the cooling tank 1, a first chute 3 inside the cooling tank 1, a first slider 4 slidably connected to the inner surface of the first chute 3, two first sliders 4 distributed front and back, a first threaded rod 5 threadedly connected to the inside of the first slider 4, the outer surface of the first threaded rod 5 rotatably connected to the cooling tank 1, a knob 20 fixedly connected to the upper end of the first threaded rod 5, a first synchronous wheel 6 fixedly connected to the outer surface of the first threaded rod 5, the lower surface of the first synchronous wheel 6 slidably connected to the cooling tank 1, and a first synchronous belt 7 drivingly connected to the outer surface of the first synchronous wheel 6. Through the cooperation between the first synchronous wheel 6 and the synchronous belt 7, the threaded rod on the other side can be rotated simultaneously, reducing the difficulty of operation. The position of the limiting roller 9 can be adjusted by rotating only one side. A mounting frame 8 is fixedly connected to the rear surface of the first slider 4, the rear surface of the mounting frame 8 is slidably connected to the cooling tank 1, and the limiting roller 9 is rotatably connected inside the mounting frame 8.

[0027] A collection trough 10 is provided on the left surface of the cooling pool 1. A bracket 11 is fixedly connected to the front surface of the collection trough 10. There are two brackets 11, which are arranged one in front of the other. A second sliding groove 12 is provided inside the bracket 11. A second slider 13 is slidably connected to the inner surface of the second sliding groove 12. A second threaded rod 14 is threaded inside the second slider 13. The second threaded rod 14 is a bidirectional threaded rod that can control the two second sliders 13 to move in opposite directions. The outer surface of the second threaded rod 14 is rotatably connected to the bracket 11. A second synchronous wheel 15 is fixedly connected to the upper end of the second threaded rod 14. The lower surface of the second synchronous wheel 15 is connected to the bracket 11. The bracket 11 is slidably connected, and the outer surface of the second synchronous pulley 15 is connected to the second synchronous belt 16. Through the cooperation between the second synchronous pulley 15 and the second synchronous belt 16, the use of motors is reduced, the cost of equipment is reduced, and the transmission speed on both sides is kept consistent. The bracket 11 is internally fixedly connected to a servo motor 17. The output end of the servo motor 17 is fixedly connected to the second threaded rod 14.

[0028] Working principle: By passing the nylon yarn through the limiting groove on the limiting roller 9, the knob 20 is rotated. The rotation of the knob 20 drives the first threaded rod 5 to rotate, which in turn drives the first slider 4 to slide. The sliding of the first slider 4 drives the mounting frame 8 to slide, which in turn drives the limiting roller 9 to slide up and down, thereby controlling the nylon yarn to be immersed in the cooling pool. The nylon yarn is then passed through the absorbent sponge 19. When the nylon yarn is wound up, it rubs against the two absorbent sponges 19, thereby wiping away the moisture on the surface of the nylon yarn. By starting the servo motor 17, the servo motor 17 drives the second threaded rod 14 to rotate. The rotation of the second threaded rod 14 drives the two second sliders 13 to slide, which in turn drives the connecting plate 18 to slide. The connecting plate 18 causes the two absorbent sponges 19 to squeeze against each other, thereby squeezing out the moisture inside the absorbent sponges 19.
