Description

Technical Field

[0001] This utility model relates to the field of fiber spinning technology, specifically a filter assembly for nylon fiber spinning. Background Technology

[0002] When spinning nylon fibers, the nylon fiber raw material particles need to be processed into a molten state. Large particles have low melting efficiency, and incomplete melting of particles during processing will affect the normal operation of spinning. Therefore, it is necessary to filter and separate the nylon fiber raw material particles delivered by the vacuum pump to filter out the large particles.

[0003] As disclosed in the patent announcement CN219664342U, a polyester fiber spinning filtration and separation device includes a support assembly, a feeding assembly, a filtration and separation assembly, and a drive mechanism. The feeding assembly is installed on top of the support assembly; the filtration and separation assembly is installed on the left side of the feeding assembly; and the drive mechanism is installed on the left side of the feeding assembly. The beneficial effects of this invention are as follows: when the motor is working, the filtration and separation cylinder rotates, preventing larger particles from clogging the filtration and separation holes. The ring of filtration and separation holes effectively filters and separates the polyester fiber raw material particles. The sealing cap facilitates the removal of larger particles from inside the filtration and separation cylinder by the operator.

[0004] Although the aforementioned patent features a sealing cap, the design of the horizontally elongated cylindrical body with a single-sided door makes it extremely difficult to clean particles far from the end cap. For nylon production, ensuring thorough cleaning each time is crucial, as any large, unmelted particles remaining could become a hidden danger for the next production run. Utility Model Content

The guiding mechanism includes an annular groove 8 formed on the inner wall of the end cap 3 and an annular groove 9 formed on the inner wall of the guide shell 4. A sealing ring 27 rotatably connected to the annular groove 8 is fixedly connected to the left outer periphery of the screening roller 5, and a sealing ring 10 rotatably connected to the annular groove 9 is fixedly connected to the right outer periphery of the screening roller 5.

At the top right side of the vertical frame 6, a rotating mechanism is provided between the vertical frame 6 and the bottom of the screening drum 5. The rotating mechanism includes a horizontal plate 11 fixedly connected to the right side support 2 and the vertical frame 6, and a gear ring 12 fixedly connected to the outer circumference of the right side of the screening drum 5. A motor 13 is fixedly connected to the top of the horizontal plate 11, and a gear 14 meshing with the gear ring 12 is fixedly connected to the output shaft of the motor 13. A fixed barrel 15 is fixedly connected to the top left side of the vertical frame 6. One end of the fixed barrel 15 extends into the screening drum 5, and the outer circumference of the fixed barrel 15 is rotatably connected to the corresponding inner circumference of the screening drum 5 through a sealed bearing. The middle part of the fixed barrel 15 and the upper part of the vertical frame 6 are also connected. A feeding pipe 16 is fixedly connected between the ends, and an arc-shaped pusher plate 7 is located inside the screening drum 5 on the lower right side. A feeding mechanism is provided between the arc-shaped pusher plate 7 and the end cover 3. The feeding mechanism includes an electric push rod 17 that is horizontally fixedly connected to the middle of the right side of the vertical frame 6, and an arc-shaped guide groove 18 that passes through the bottom of the end cover 3. The output shaft of the electric push rod 17 passes through the fixed barrel 15 and is fixedly connected to the right side of the arc-shaped pusher plate 7. An arc-shaped baffle 19 is slidably connected inside the arc-shaped guide groove 18. Horizontal crossbars 20 are fixedly connected to both sides of the arc-shaped pusher plate 7 near the arc-shaped baffle 19. A through-hole is provided at the middle of the bottom end of the end cover 3. The feeding trough 21 is connected to the arc-shaped guide trough 18. The feeding mechanism also includes a telescopic groove 22 opened on the left side of the end cover 3 and close to the arc-shaped guide trough 18, and a connector 23 vertically fixedly connected to the outside of the left side of the arc-shaped baffle 19. A telescopic rod 24 that slides with the telescopic groove 22 is fixedly connected to the top right side of the connector 23. A limit ring 25 is fixedly connected to the right end of the telescopic rod 24. A spring 26 is movably sleeved on the outside of the telescopic rod 24. The two ends of the spring 26 abut against the telescopic groove 22 and the limit ring 25 respectively. An arc-shaped hopper 28 is fixedly connected between the two supports 2 and below the screening drum 5.

[0028] In this embodiment, the mechanized automatic discharge of large particles is achieved by using the screening drum 5 in conjunction with the arc-shaped pusher plate 7, which effectively solves the problem of difficult cleaning of particles at the far end inside the transverse long cylinder.

[0029] Furthermore, the automatic opening, closing and sealing of the discharge chute 21 are achieved through the combined use of the arc-shaped pusher plate 7 and the spring 26, which greatly improves the efficiency and convenience of cleaning operations while ensuring the sealing performance during normal screening operations.

[0030] Working principle: Nylon fiber raw material particles are conveyed through the feeding pipe 16 to the inside of the fixed barrel 15 and then enter the continuously rotating screening drum 5. The motor 13 drives the screening drum 5 to rotate around its axis through the meshing of the gear 14 and the gear ring 12. The sealing ring 27 and sealing ring 10 at both ends of the screening drum 5 rotate in the annular groove 8 of the end cover 3 and the annular groove 9 of the guide shell 4, respectively, to achieve dynamic sealing. Qualified fine particles are thrown out through the screen holes on its wall by centrifugal force during the rotation of the screening drum 5 and are finally collected by the arc-shaped hopper 28. Unqualified large particles are retained on the inner wall of the screening drum 5. When it is necessary to remove these residual large particles... The electric push rod 17 is activated to push the arc-shaped pusher plate 7 to slide along the inner wall of the screening drum 5. The arc-shaped pusher plate 7 pushes the arc-shaped baffle 19 to slide along the arc-shaped guide groove 18 through the crossbars 20 at both ends of the arc-shaped pusher plate 7, thus opening the channel connected to the discharge chute 21. Then the arc-shaped pusher plate 7 continues to move forward and pushes the residual particles out of the screening drum 5 through the discharge chute 21 via the channel. After cleaning is completed, the electric push rod 17 retracts and the arc-shaped pusher plate 7 returns to its original position. At this time, under the action of the spring 26, the arc-shaped baffle 19 is pulled in the opposite direction in the arc-shaped guide groove 18 by the telescopic rod 24 and the connecting piece 23 until the discharge chute 21 is closed again, and the screening operation is restored.

[0031] In the specific implementation of this technical solution, the control method for motor 13 and electric push rod 17 can be configured with conventional controllers in the prior art (such as PLC controllers, microcontroller controllers, industrial PCs, or dedicated motor motion controllers). Although these controllers are not described in detail in the technical solution, they are standard components that can be conventionally selected by those skilled in the art according to actual automation control needs. Their programming logic, signal interfaces, and control algorithms follow well-known technologies in the field and do not affect the implementation of the core innovation of this solution. In practical applications, the controller is mainly used to coordinate the start, stop, and speed of motor 13, as well as the extension and retraction stroke and timing of electric push rod 17. However, its specific model and control strategy can be adjusted according to the degree of automation and control accuracy requirements of the production line, all of which fall within the reasonable extension range of this technical solution.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
