Description

Technical Field

[0001] This invention relates to the field of spinning equipment technology, specifically to a glue removal device for spinning acrylic filaments. Background Technology

[0002] Acrylic fiber wet spinning is a key production technology that involves dissolving polyacrylonitrile polymer in an organic solvent to create a spinning solution, which is then forced through the fine orifices of a spinneret into a coagulation bath composed of a mixture of the solvent and water. Through a double diffusion process, the solvent precipitates from the fine stream of the solution, and the polymer solidifies. Subsequent post-processing steps, including stretching, washing, oiling, and drying, produce fibers. Its core significance lies in the fact that this process, through a gentle liquid-phase coagulation process, allows for precise control of the fiber's microstructure, resulting in high-performance, soft-handed, and easily dyeable acrylic fibers. It is particularly suitable for producing imitation silk, wool-like fibers, and high-performance carbon fiber precursors, and is a cornerstone technology for the industrialization, functionalization, and high-value development of modern acrylic fibers.

[0003] To address this, existing technology discloses a wet spinning device with publication number "CN222499487U," which relates to the field of spinning equipment. The device includes a coagulation bath capable of accommodating spinning movement, a spinning nozzle facing the inner side of the coagulation bath, and a first traction roller group located outside the coagulation bath. The coagulation bath is equipped with a first guide structure and a second guide structure, which are respectively located near the spinning nozzle and the first traction roller group. The first guide structure effectively prevents filaments from accumulating or gathering below the spinning nozzle, thus not affecting the continuous ejection of subsequent filaments. The second guide structure allows the spinning path formed inside the coagulation bath to smoothly tilt upwards, maintaining the continuity of the spinning process and effectively preventing the filaments from accumulating again inside the coagulation bath after passing through the first guide structure. This facilitates the rapid entry of the filaments into the next process, improving the efficiency of the spinning process.

[0004] However, the aforementioned device still has significant technical shortcomings: when cleaning the nozzles, the spinning nozzles need to be lifted upwards and removed from the coagulation bath to expose them to the air for glue removal. This method has significant drawbacks: firstly, it requires manual lifting of the spinning nozzles, resulting in low automation; secondly, it disrupts the stable coagulation bath environment. In large coagulation baths, multiple sets of spinning nozzles are typically arranged, and the spinning nozzles cause significant flow around the liquid during the tumbling process, affecting the normal spinning operation of the other spinning nozzles. These problems have become bottlenecks restricting the automation upgrade and efficient and stable operation of production lines. Therefore, it is crucial to develop a device with a high degree of automation that reduces the flow around the coagulation bath liquid during glue removal. Summary of the Invention

[0005] Therefore, it is necessary to provide a glue removal device for spinning acrylic filaments to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A glue removal device for spinning acrylic filament includes: The coagulation bath has several assembly ball openings on its side wall; A plurality of spinning balls are provided, each of which is rotatably mounted on a corresponding assembly ball opening. Each spinning ball includes a detachable spherical seat and a spinning spray plate. By rotating the spherical seat, the spinning spray plate can be selectively directed toward the spinning station inside the coagulation bath or toward the glue discharge station outside through the assembly ball opening. The plurality of spinning balls are connected to a metering pump through corresponding pipes. Several gas phase isolation hoods are respectively disposed above one of the spinning ball heads and can move up and down to displace the coagulated bath liquid around the corresponding spinning ball head and form a temporary gas phase operating space when descending. A glue discharge guide channel is fixedly installed below the assembly ball opening to receive and guide the glue discharged from the spinning ball head; A glue collection bucket is located at the end of the glue discharge channel and is used to collect glue liquid.

[0007] Preferably, the spherical seat and the spinning spray plate are threadedly fixedly connected. The spinning hole on the spinning spray plate is connected to the adhesive chamber inside the spherical seat. The spinning ball head is fixedly connected to a sealing shaft on both sides of the adhesive chamber. One of the sealing shafts is provided with an adhesive inlet hole that communicates with the adhesive chamber. The coagulation bath is also provided with an adhesive inlet channel that communicates with the adhesive inlet hole on the side of the assembly ball. The adhesive inlet channel is connected to a metering pump through a connecting pipe, so that the adhesive is pumped into the spinning ball head by the metering pump.

[0008] Preferably, the inner side of the assembly ball opening is also provided with multiple sealing grooves on the same axis, and each sealing groove is equipped with a sealing rubber ring. The sealing rubber rings are tightly abutted against the ball seat to prevent the coagulation bath liquid from flowing out through the assembly ball opening.

[0009] Preferably, the side of the coagulation bath with the assembly ball opening is inclined outward to form a slope, so that when the spinning spray plate is in the glue discharge position parallel to the outer wall of the coagulation bath, the opening of the spinning spray plate is inclined downward.

[0010] Preferably, sealing rings are installed on both sides of the sealing shaft, and a sealing assembly groove is provided on the coagulation bath for the sealing shaft and sealing ring to be embedded. The sealing shaft is limited and installed in the sealing assembly groove by a sealing seat, so that the spinning ball head rotates around the sealing shaft. A torsion spring is also sleeved on the sealing shaft, and the torsion spring causes the spinning ball head to rotate to the spinning position without external force.

[0011] Preferably, bolt mounting holes are provided on the sealing seat and the coagulation bath, and the sealing seat is fixedly installed inside the coagulation bath by tightening bolts.

[0012] Preferably, the slope of the vapor phase isolation hood is matched with that of the coagulation bath, and its bottom and the side near the coagulation bath are designed with an open type. A sealing strip is installed on the side of the vapor phase isolation hood that abuts against the coagulation bath, and a corresponding sealing groove is opened on the coagulation bath. During the raising and lowering of the vapor phase isolation hood, the airtightness of the inner space of the vapor phase isolation hood is achieved through the cooperation of the sealing strip and the sealing groove.

[0013] Preferably, the coagulation bath is also fixedly installed with several sets of lifting guide rails inside the assembly ball opening, and the two sides of the gas phase isolation cover are slidably engaged with the lifting guide rails through the installed track wheels.

[0014] Preferably, the upper end of several sets of lifting guide rails is also fixedly installed with an mounting plate, and an electric push rod is correspondingly installed on the mounting plate. The telescopic arm of the electric push rod is fixedly connected to the gas phase isolation hood, thereby driving the gas phase isolation hood to move up and down through the electric push rod.

[0015] Preferably, a telescopic guide bar is also fixedly installed inside the gas phase isolation hood. The telescopic guide bar is movably engaged with the rotating gear. The rotating gear is fixedly installed on the sealing shafts on both sides. When the gas phase isolation hood descends and the telescopic guide bar engages with the rotating gear, the descent of the gas phase isolation hood drives the rotating gear to rotate, thereby driving the spinning ball head to change from the glue discharge station to the spinning station.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The spinning nozzle of this invention adopts a special structural design, which enables it to change its working mode through its own fixed-axis rotational movement, and its flipping process no longer requires manual operation. At the same time, in order to ensure that no leakage of coagulation bath occurs during the flipping process, a gas phase isolation hood is used to form a temporary gas phase operating space. For large coagulation bath tanks with multiple sets of spinning nozzles, this kind of setting has less disturbance to the coagulation bath due to its cut-in sealing method, which fully ensures the normal operation of the remaining spinning nozzles and improves the automation level of the device.

[0025] Please see Figure 1-7 The present invention provides the following technical solution: Example

[0026] In this embodiment, the core design of this application lies in the cooperation between the rotatable spinning ball head 3 and the liftable gas phase isolation hood 6 to achieve isolation and automated glue removal of a single spinning head, thereby avoiding affecting the overall stability of the coagulation bath. Its main structure includes: Main frame and coagulation bath The main body of the device is a coagulation bath 1, which is used to contain the coagulation bath liquid. Multiple assembly nozzles 2 are machined on the side wall at the front end of the coagulation bath 1 in the liquid flow direction for installing spinning ball heads 3. Specifically, such as... Figure 1 and Figure 2 As shown, the sidewall of the coagulation bath 1, where the assembly ball nozzle 2 is located, is designed with an outwardly sloping surface. This design allows the spinneret surface to naturally tilt downwards when the subsequent spinning ball head 3 is flipped to the outside, which in turn facilitates the falling of the adhesive liquid under its own gravity.

[0027] Spinning ball assembly The spinning ball head 3 is a key actuator of this device, which switches its working position through fixed-axis rotation. For example... Figure 3 As shown, each spinning ball head 3 is mainly composed of two parts: a spherical seat 4 and a spinning spray plate 5, which are detachably connected by threads. The spherical seat 4 is hollow inside to form a glue chamber 11, and the spinning spray plate 5 is densely covered with spinning holes 10 for extruding the spinning solution. The spinning holes 10 are connected to the glue chamber 11.

[0028] To achieve fixed-axis rotation and sealing, sealing shafts 12 are integrally formed on both sides of the spherical seat 4. One of the sealing shafts 12 has a glue inlet hole 13, which communicates with the glue tank 11. The coagulation bath 1 has a glue inlet channel 14 machined at the corresponding position. The glue inlet channel 14 is connected to an external metering pump through a connecting pipe 15, thereby accurately pumping the spinning solution into the glue tank 11. The metering pump and the connecting pipe are not shown in detail. This part of the structure is a mature technical solution in the prior art and will not be described in detail here.

[0029] The rotational support and sealing of the spinning ball head 3 are achieved through the following structure: a sealing assembly groove 17 is correspondingly opened on the coagulation bath 1, the sealing shaft 12 and the sealing ring 16 fitted on it are embedded therein, and then the sealing seat 18 is covered by the sealing seat 18, and the sealing seat 18 is fastened to the coagulation bath 1 by passing the fastening bolt 20 through the bolt assembly hole 19, thereby rotatably limiting the spinning ball head 3 at the assembly ball opening 2. The sealing seat 18 and the coagulation bath 1 are correspondingly opened with bolt assembly holes 19, and the sealing seat 18 is fixedly installed inside the coagulation bath 1 by the fastening bolt 20. In addition, a torsion spring is also fitted on the sealing shaft 12. When no external force is applied, the torsion spring keeps the spinning ball head 3 pointing towards the spinning position inside the coagulation bath 1. The structure of the torsion spring is not shown in the attached drawings. This structure is also a common structure in the prior art. The torsion spring fitted on the sealing shaft 12 applies torque to the sealing shaft 12, thereby keeping it in the spinning position when no external force is applied. This technical solution will not be described in detail. In order to further ensure the accuracy of the rotation position of the spinning ball head 3, a limiting block can be installed on the sealing shaft 12, so that it can be more accurately positioned in the spinning position or the glue discharge position. Refer to the attached manual. Figure 1 and Figure 2 In the spinning station, the spinning nozzle 5 of the spinning ball head 3 is set perpendicular to the bottom plate of the coagulation bath 1, so that the orientation of the spinning nozzle 5 is consistent with the flow direction of the coagulation bath liquid, thereby improving the spinning operation. In the glue removal station, the spinning nozzle 5 is set parallel to the outer side of the coagulation bath 1, which ensures that all the spinning holes 10 on the spinning nozzle 5 are unobstructed, thus enabling the glue removal operation to proceed smoothly.

[0030] To ensure that the coagulation bath does not leak when the spinning ball head 3 transitions from the spinning station to the glue discharging station, such as Figure 5 As shown, multiple coaxial sealing grooves are machined on the inner side of the assembly ball 2, and sealing rings, such as O-rings, are installed in the grooves. When the ball seat 4 rotates to different angles, these sealing rings can always maintain close contact with the spherical surface of the ball seat 4, thereby achieving dynamic sealing.

[0031] Vapor phase isolation hood and its drive mechanism The vapor phase isolation hood 6 is the core of the isolation operation. Each spinning ball head 3 is equipped with a corresponding vapor phase isolation hood 6 above it. The side shape of the vapor phase isolation hood 6 matches the inclined side wall of the coagulation bath 1. Its bottom and the side near the coagulation bath 1 are open, so that the spinning ball head 3 can be covered smoothly during the descent.

[0032] The vapor phase isolation hood 6 moves via a lifting mechanism. Specifically, several sets of vertical lifting guide rails 22 are fixedly installed inside the coagulation bath 1, and track wheels (not shown in the figure) are installed on both sides of the vapor phase isolation hood 6, allowing it to rise and fall smoothly along the lifting guide rails 22. A mounting plate 23 is fixedly fixed to the top of all the lifting guide rails 22, and an electric push rod 24 is correspondingly installed on the mounting plate 23. The telescopic arm of the electric push rod 24 is fixedly connected to the top of the vapor phase isolation hood 6, thereby driving the rise and fall of the vapor phase isolation hood 6 by controlling the extension and retraction of the electric push rod 24.

[0033] To achieve airtight isolation, such as Figure 7 As shown, a sealing strip is installed at the edge where the vapor phase isolation hood 6 contacts the side wall of the coagulation bath 1. Correspondingly, a sealing groove 21 that mates with the sealing strip is machined on the side wall of the coagulation bath 1. When the vapor phase isolation hood 6 descends, the sealing strip is pressed into the sealing groove 21, thereby forming a temporary, basically sealed vapor phase operating space around the target spinning ball head 3 between the vapor phase isolation hood 6, the side wall of the coagulation bath 1, and the liquid surface, displacing the internal coagulation bath liquid.

[0034] glue collection system On the outside of the coagulation bath 1, below the assembly ball inlet 2, a glue discharge guide trough 7 is fixedly installed. The glue discharge guide trough 7 is used to collect waste glue or cleaning liquid flowing out from the spinning ball head 3 at the glue discharge station. The end of the glue discharge guide trough 7 is connected to a glue collection tank 9 for centralized collection and temporary storage of waste liquid. Example

[0035] A telescopic guide bar 25 is also fixedly installed inside the gas phase isolation cover 6. The telescopic guide bar 25 is movably engaged with the rotating gear 26. The rotating gear 8 is fixedly installed on the sealing shafts 12 on both sides. When the gas phase isolation cover 6 descends and the telescopic guide bar 25 engages with the rotating gear 26, the descent of the gas phase isolation cover 6 drives the rotating gear 8 to rotate, thereby driving the spinning ball head 3 to change from the glue discharge station to the spinning station.

[0036] In this embodiment, to reduce the need for an electrically driven structure, a telescopic guide bar 25 is fixedly installed inside the gas phase isolation shield 6. This telescopic guide bar 25 is in movable engagement with the rotating gear 8 mounted on the sealing shaft 12. (Refer to the appendix of the instruction manual.) Figure 6 and Figure 7When the gas phase isolation hood 6 is in the upper position, the telescopic guide 25 disengages from the sealing shaft 12. At this time, the raising and lowering of the gas phase isolation hood 6 will not cause the spinning ball head 3 to rotate. During the descent of the gas phase isolation hood 6, the gas inside the gas phase isolation hood 6 is gradually emptied. When the telescopic guide 25 engages with the rotating gear 8, the spinning ball head 3 is ready to rotate. As the gas phase isolation hood 6 moves downward, the telescopic guide 25 pushes the rotating gear 8 to rotate, thereby causing the sealing shaft 12 to overcome the elastic force of the torsion spring and rotate downward, thus changing its state. This achieves the linkage switching from the spinning operation to the glue discharge station. To ensure the spinning... To ensure that the spinning ball head 3 can accurately stop at the glue discharge station, the telescopic guide 25 and the number of teeth of the rotating gear 8 need to be properly set so that when the gas phase isolation cover 6 reaches its lowest position, the spinning ball head 3 is exactly at the glue discharge station. This setting allows the spinning ball head 3 to rotate without the need for an additional motor. Furthermore, by linking its rotational movement with the gas phase isolation cover 6, the rotational sequence of the two can be matched more accurately. This ensures that a temporary gas phase operating space has been formed inside the gas phase isolation cover 6 before the spinning ball head rotates. After the glue discharge is completed, the telescopic guide 25 moves upward along with the gas phase isolation cover 6, driving the spinning ball head 3 to rotate and reset during this process.

[0037] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
