Description

Technical Field

[0001] This utility model relates to a nylon fiber production apparatus, and more particularly to a nylon fiber production apparatus applied in the field of nylon fiber production. Background Technology

[0002] Nylon fiber is widely used in many fields such as textiles, clothing, and industrial manufacturing due to its excellent abrasion resistance and high strength. In the production process of nylon fiber, the spinning process is crucial. However, in this process, due to friction and other reasons, fiber fibers will adhere to the nylon spinning due to static electricity.

[0003] Chinese utility model patent CN202321355814.8 discloses a highly realistic nylon fiber production device, including a textile machine body. An unwinding shaft and a spiral rod are rotatably connected to the inner wall of the textile machine body. Fabric connected to the spiral rod is sleeved on the unwinding shaft. The device achieves this by winding the fabric around the unwinding shaft and spiral rod onto a take-up shaft. A drive motor rotates the spiral rod to take up the fabric. After one roll is taken up, a pusher plate is moved outwards, causing the spiral rod to rotate and push the upper roll onto a bracket in the feeding box for unloading from the discharge port. Subsequently, a spare roll is automatically inserted into the bracket from the feeding box. The pusher plate then pushes the spare roll onto the spiral rod in the feeding port. The position of the pusher plate is fixed, positioning the spare roll on the spiral rod to prevent it from being pushed out when the spiral rod rotates, effectively achieving automatic and rapid roll replacement.

[0004] However, the aforementioned nylon fiber production equipment typically uses cleaning brushes, air jets, or suction to clean the fibers on the spinning process. Because nylon spinning exhibits a strong attraction to these fibers under electrostatic effects, these traditional cleaning techniques are insufficient to completely remove them. As a result, the residual fibers not only affect the appearance quality of the nylon fibers, making their surface less smooth, but may also cause fiber entanglement and increased breakage during subsequent stretching, twisting, and weaving processes, thereby reducing production efficiency, increasing production costs, and in severe cases, affecting the performance and quality of the final product. Therefore, developing a production device that can effectively remove fiber fuzz from nylon spinning is an urgent practical need to improve the quality and efficiency of nylon fiber production. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is how to effectively remove fiber fuzz from nylon spinning.

[0006] To address the aforementioned problems, this utility model provides a nylon fiber production device, including a cleaning cylinder, and further comprising: a first hollow ring, fixedly connected inside the cleaning cylinder near the feed end; a first jet pipe, circumferentially and equidistantly connected to the first hollow ring, with the jet nozzle of the first jet pipe inclined towards the discharge end of the cleaning cylinder; a gas delivery pipe, installed on the cleaning cylinder, with its gas delivery port connected to the first hollow ring, and its gas inlet connected to an external device capable of generating a large number of positively and negatively charged gas masses; a semi-circular hollow ring, symmetrically and fixedly connected inside the cleaning cylinder, with multiple suction pipes equidistantly connected to the semi-circular hollow ring; a vacuum pump, located on one side of the cleaning cylinder; a first three-way pipe, with its outlet connected to the suction port of the vacuum pump, and its two suction ports each connected to one of the semi-circular hollow rings; a conveying pipe connected to the outlet end of the vacuum pump, and a filter assembly for filtering out fiber fibers from the gas.

[0007] In the aforementioned nylon fiber production device, positively charged air masses are used to eliminate the negative static charge on the nylon spinning fibers, so that the fiber fibers are no longer firmly attached due to static electricity and are easier to remove. By combining air jetting and suction, not only can the fiber fibers be effectively blown off, but the blown-off fiber fibers can also be promptly absorbed and collected.

[0008] As a further improvement of this application, the filtration assembly includes a separation tank, a tank cover, and a separation filter plate. The separation tank is disposed on one side of the cleaning cylinder, the tank cover is closed on the opening at the upper end of the separation tank, the air pump is installed on the tank cover, the delivery pipe passes through the tank cover and extends into the separation tank, an exhaust pipe is connected to the lower end of one side of the separation tank, and the separation filter plate is disposed inside the separation tank and located above the exhaust pipe.

[0009] As a further improvement to this application, the separation filter plate is a conical filter plate.

[0010] As a further improvement of this application, a ring-shaped protrusion is provided inside the separation barrel below the separation filter plate. The separation filter plate is placed on the ring-shaped protrusion. A vertical rod is fixedly connected to the upper end of the separation filter plate. A fan blade assembly is fixedly connected to the upper end of the vertical rod. The air outlet of the conveying pipe faces the fan blade assembly.

[0011] As another improvement of this application, a ring-shaped collection box is fixedly connected to the outside of the separation filter plate.

[0012] As a further improvement of this application, a second hollow ring is fixedly connected to the side of the cleaning cylinder near the discharge end. Multiple second air jet pipes are connected in a circular pattern at equal intervals on the second hollow ring. The air jet nozzles of the second air jet pipes are inclined towards the feed end of the cleaning cylinder. The air delivery pipe is a second three-way pipe, and the other air outlet of the second three-way pipe is connected to the second hollow ring.

[0013] As a further improvement of this application, both the feed end and the discharge end of the cleaning cylinder are rotatably connected to a rotating shaft, and a support wheel is fixedly connected to the rotating shaft.

[0014] In summary, compared with existing technologies that simply use cleaning brushes, air jets, or suction to clean fiber lint, this nylon fiber production device utilizes positively charged air masses to eliminate the negative static charge on the nylon spinning process. This prevents the fiber lint from adhering firmly due to static electricity, making it easier to remove. By combining air jets and suction, not only can the fiber lint be effectively blown off, but it can also be promptly absorbed and collected to prevent it from re-adhering or scattering and affecting the production environment. Furthermore, the separation filter plate in the separation tank can intercept and filter out the fiber lint, achieving gas-solid separation and ensuring the cleanliness of the discharged gas. This effectively reduces the impact of fiber lint on subsequent processing steps, improving the production quality and efficiency of nylon fibers. Attached Figure Description

[0021] The first embodiment of this application will now be described in detail with reference to the accompanying drawings.

[0022] First implementation method:

[0023] Figures 1-4The diagram shows a nylon fiber production apparatus, including a cleaning cylinder 1, and further comprising: a first hollow ring 103 fixedly connected inside the cleaning cylinder 1 near the feed end; a first air jet pipe 104 circumferentially and equidistantly connected to the first hollow ring 103, the air jet nozzle of the first air jet pipe 104 being inclined towards the discharge end of the cleaning cylinder 1; an air supply pipe 105 installed on the cleaning cylinder 1, the air supply port being connected to the first hollow ring 103, and the air inlet of the air supply pipe 105 being connected to an external device capable of generating a large number of positively and negatively charged air masses; and a semi-circular hollow ring 10... 8. Symmetrically fixedly connected inside the cleaning cylinder 1, a plurality of suction pipes 109 are equidistantly connected on the semi-circular hollow ring 108; a vacuum pump 202 is set on one side of the cleaning cylinder 1; a first three-way pipe 203, the outlet of the first three-way pipe 203 is connected to the suction port of the vacuum pump 202, and the two suction ports of the first three-way pipe 203 are respectively connected to one of the semi-circular hollow rings 108; the outlet end of the vacuum pump 202 is connected to a delivery pipe 204, and the outlet end of the delivery pipe 204 is connected to a filter assembly for filtering out fibers in the gas.

[0024] The filtration assembly includes a separation tank 2, a tank cover 201, and a separation filter plate 206. The separation tank 2 is located on one side of the cleaning tank 1. The tank cover 201 covers the opening at the upper end of the separation tank 2. The air pump 202 is installed on the tank cover 201. The delivery pipe 204 passes through the tank cover 201 and extends into the separation tank 2. An exhaust pipe 2010 is connected to the lower end of one side of the separation tank 2. The separation filter plate 206 is located inside the separation tank 2 and above the exhaust pipe 2010.

[0025] In the spinning stage of nylon fiber production, after the nylon filaments enter the cleaning cylinder 1, the air supply pipe 105, which is connected to the external equipment that generates a large number of positively charged air masses, starts working, delivering the positively charged air masses to the first hollow ring 103. Since the first jet pipe 104 is circumferentially and equidistantly connected to the first hollow ring 103, and the jet nozzle is inclined towards the discharge end of the cleaning cylinder 1, the positively charged air masses are sprayed onto the nylon filaments through the first jet pipe 104. Because the static electricity on the nylon filaments is usually negative, the sprayed positively charged air masses interact with it, thereby eliminating the static electricity on the nylon filaments. At the same time, the high-speed compressed air can blow away the fiber fuzz that was originally firmly attached to the nylon filaments due to static electricity. While the air jet is cleaning the fiber fuzz, the vacuum pump 202 is activated. The air pump 202 is connected to the semi-circular hollow ring 108 symmetrically arranged inside the cleaning cylinder 1 through the first three-way pipe 203. Multiple suction pipes 109 are connected at equal intervals on the semi-circular hollow ring 108. When the air pump 202 is working, it will cause the suction pipes 109 to generate suction force, which will draw the blown-away fibers into the separation tank 2. The separation tank 2 is equipped with a separation filter plate 206. After the fibers enter the separation tank 2 with the airflow, the separation filter plate 206 can intercept and filter out the fibers. The purified gas is discharged through the exhaust pipe 2010 at the lower end of one side of the separation tank 2.

[0026] Compared with existing technologies that simply use cleaning brushes, air jets, or suction to clean fiber lint, this nylon fiber production device utilizes positively charged air masses to eliminate the negative static charge on the nylon spinning process. This prevents the fiber lint from adhering firmly due to static electricity, making it easier to remove. By combining air jets and suction, not only can the fiber lint be effectively blown off, but the blown-off fiber lint can also be promptly absorbed and collected to prevent it from re-adhering or scattering and affecting the production environment. Furthermore, the separation filter plate 206 in the separation tank 2 can intercept and filter out the fiber lint, achieving gas-solid separation and ensuring the cleanliness of the discharged gas. This effectively reduces the impact of fiber lint on subsequent processing steps and improves the production quality and efficiency of nylon fiber.

[0027] Figures 3-4 As shown, the separation filter plate 206 is a conical filter plate. On the one hand, its special conical shape increases the contact area with the airflow, making it easier to intercept fibers in the airflow and improve the filtration efficiency. On the other hand, the conical structure allows the intercepted fibers to slide down the inclined surface to the bottom of the separation filter plate 206, making it less likely to accumulate on the filter plate surface, reducing the risk of clogging, ensuring the air permeability of the filter plate, and continuously and stably separating and filtering fibers in the airflow.

[0028] Inside the separation tank 2, below the separation filter plate 206, there is a ring of protrusions 205. The separation filter plate 206 is placed on the ring of protrusions 205. A vertical rod 208 is fixedly connected to the upper end of the separation filter plate 206. A fan blade assembly 209 is fixedly connected to the upper end of the vertical rod 208. The air outlet of the conveying pipe 204 faces the fan blade assembly 209.

[0029] An annular protrusion 205 is provided inside the separation tank 2 to house the separation filter plate 206. This design facilitates the installation and disassembly of the separation filter plate 206, and makes it easy to clean and maintain the filter plate. The vertical rod 208 and the fan blade assembly 209 connected to the upper end of the separation filter plate 206 cooperate with the air outlet of the conveying pipe 204 facing the fan blade assembly 209. When the air pump 202 is working, the gas is ejected through the conveying pipe 204 and impacts the fan blade assembly 209, which will drive the fan blade assembly 209, the vertical rod 208 and the separation filter plate 206 to rotate together. The centrifugal force generated by the rotation of the separation filter plate 206 can throw the fiber hairs attached to the surface of the filter plate towards the inner wall of the separation tank 2, avoiding the accumulation of fiber hairs on the surface of the filter plate, thereby effectively reducing the clogging of the filter plate. This not only ensures the continuous good filtration effect of the separation filter plate 206, but also makes the air extraction process stable, improving the fiber hair removal efficiency and stability of the entire nylon fiber production device.

[0030] A ring-shaped collection box 207 is fixedly connected to the outer side of the separation filter plate 206.

[0031] The annular collection box 207 can effectively collect fiber fluff, which is convenient for later cleaning. It eliminates the need for a complete cleaning of the entire separation tank 2, saving maintenance time and effort, improving the ease of use of the device, and ensuring the continuity and efficiency of fiber fluff filtration in the nylon fiber production device.

[0032] Figure 2 As shown, a second hollow ring 106 is fixedly connected to one side of the cleaning cylinder 1 near the discharge end. Multiple second air jet pipes 107 are circumferentially and equidistantly connected on the second hollow ring 106. The air jet nozzles of the second air jet pipes 107 are inclined towards the feed end of the cleaning cylinder 1. The air supply pipe 105 is a second three-way pipe. The other air outlet of the second three-way pipe is connected to the second hollow ring 106. After the nylon spinning is cleaned by the air jet of the first hollow ring 103 and the first air jet pipe 104, some fiber hairs may still remain. At this time, the positively charged air mass sprayed from the second air jet pipe 107 inclined towards the feed end can perform a secondary cleaning of the nylon spinning. These reverse-jet airflows can impact the nylon spinning at various angles, blowing away the fiber hairs that were not completely blown off or that re-attached to the spinning due to the airflow, further improving the fiber hair removal rate and ensuring that the nylon spinning carries as few fiber hairs as possible when leaving the cleaning cylinder 1, thereby improving product quality.

[0033] The feed end and discharge end of the cleaning cylinder 1 are rotatably connected to a rotating shaft 101. A support wheel 102 is fixedly connected to the rotating shaft 101. The support wheel 102 can provide stable support for nylon spinning. When the spinning moves inside the cleaning cylinder 1, it can be positioned at the central axis of the cleaning cylinder 1 so that the gas can blow on it more comprehensively.

[0034] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
