Description

Technical Field

[0001] The present invention relates to the technical field of chemical fiber spinning, and in particular to a device and a process for uniformly oiling a filament bundle. Background Art

[0002] Yarn tow oiling is a crucial process in the production of chemical fibers (such as polyester, nylon, polypropylene, acrylic, etc.). It plays the role of lubrication, bonding, improving smoothness, protecting fibers, improving surface properties and anti-static. By evenly applying a special oil (spinning oil) to the fiber surface, the yarn tow is given a series of key properties, ensuring the smooth progress of subsequent processing (stretching, winding, texturing, weaving, etc.), and ultimately affecting the quality of the finished fibers and fabrics.

[0003] Chinese patent CN219772341U discloses a nylon 6 coarse denier tow oiling device, comprising: an oil tanker oiling assembly, including a support frame, an oil tanker, an oil tank and a first drive motor; a wire guide hook, located below the oil tank and fixedly connected to the support frame; an oil nozzle oiling assembly, including an oil nozzle and an oil receiving pan, the oil nozzle being fixedly connected to the support frame and located below the wire guide hook, the oil receiving pan being located below the oil nozzle, and the oil receiving pan being provided with an oil drain hole; and an oil agent circulation assembly, including an oil tank, an oil pump, a second drive motor, a first three-way joint and a second three-way joint.

[0004] However, in the existing technology, the yarn bundle jumps at the oil nozzle position, and the oil is easily driven to diffuse to both sides, resulting in insufficient protrusion of the oil end at the oil nozzle position, unstable contact between the yarn bundle and the oil, and thus reduced oiling effect of the yarn bundle. At the same time, because the temperature of the oil is too high or air is mixed in, foam will appear at the oil nozzle position, which will cause oil spots to appear on the oiled surface of the yarn bundle. Failure to eliminate the foam in time will seriously affect the appearance of the yarn bundle and the quality of the textile. Summary of the Invention

[0005] The purpose of the present invention is to address the shortcomings of the existing technology and provide a device and process for uniform oiling of yarn bundles. The oiling mechanism cooperates with the emergency treatment mechanism to achieve stable contact between the yarn bundle and the oil agent and timely elimination of foam and resumption of production. It solves the technical problems of the yarn bundle jumping at the oil nozzle position, the oil agent being easily driven to diffuse to both sides, the unstable contact state between the yarn bundle and the oil agent, and the appearance of foam at the oil port position affecting the appearance of the yarn bundle and the quality of the textile due to the high temperature of the oil agent or the mixing of air.

[0007] Furthermore, the gathering assembly includes an active rack whose ends are respectively connected to two groups of rotating shafts, a follower rack connected to the oil nozzle, a follower gear connected to the oil nozzle and respectively engaged with the active rack and the follower rack for transmission, and two groups of gathering plates connected to the oil nozzle and respectively connected to the two ends of the follower rack.

[0008] Furthermore, the compensation component includes an oil tank opened on the oil nozzle and located below the oil port, a compensation channel opened on the oil nozzle and connected to the oil tank, a Jiaolong screw connected in the compensation channel, a second motor connected to the oil nozzle and the output end of which is connected to the Jiaolong screw, a delivery pipe connected to the compensation channel and with two groups of outlets located on both sides of the oil port, a U-shaped rod connected to the gathering plate, and a blocking block connected to the U-shaped rod through a first telescopic member and used to close the delivery pipe.

[0009] Furthermore, the pushing assembly includes a guide plate connected to the gathering plate, a first scraper connected to the gathering plate and fitting with the top slope of the oil tank, and a second scraper connected to the bottom of the gathering plate through a second telescopic member and fitting with the slopes on both sides of the oil tank.

[0010] Furthermore, the emergency treatment mechanism includes a collecting component arranged on the oil nozzle and used to collect excess oil, an oil replenishing component arranged inside the oil nozzle and used to cooperate with the collecting component to oil the filament bundle, an avoidance component arranged on the oil nozzle and used to cover the collecting component to prevent the collected oil from contacting with the air for a long time, and a defoaming component arranged on the gathering component and used to eliminate foam.

[0011] Furthermore, the collecting assembly includes a collecting chamber opened on the oil nozzle, a collecting channel provided on the oil nozzle and connected to the oil tank, and a collecting tank provided in the collecting chamber and located below the collecting channel; The oil replenishing assembly includes a round rod connected to the oil nozzle through a slider, a third motor connected to the slider and having its output end connected to the round rod, an oil wheel connected to the round rod, a regulating frame passing through the oil nozzle and connected to the round rod, and a second driving cylinder connected to the spinning chamber and having its output end connected to the regulating frame.

[0012] Furthermore, the avoidance assembly includes a cooperative frame connected to the output end of the second driving cylinder through a third telescopic member, a plurality of avoidance tubes connected to the cooperative frame, two sets of guide rail frames connected to the oil nozzle and connected to the round rod, a door panel connected to the guide rail frame and used to close the collection chamber, a first gear connected to the guide rail frame, and a first rack respectively connected to the collection chamber and the door panel and meshing with the first gear for transmission.

[0013] Furthermore, the defoaming assembly includes a trigger plate connected to the top of the gathering plate, a second rack connected to the bottom of the trigger plate, a screw connected to the inside of the gathering plate, a second gear connected to the screw and meshing with the second rack, a slide connected to the inside of the gathering plate, a moving block connected to the screw and located inside the slide, a conveying rod connected to the moving block and passing through the gathering plate, a storage groove opened on the conveying rod, a feeding bin connected to the inside of the gathering plate, a T-rod passing through the conveying rod and the moving block and connected to the moving block by a spring, a valve plate connected to the end of the T-rod and located in the storage groove, and a protrusion connected to the slide and used to block the T-rod.

[0014] Still further, a process for uniformly oiling a tow, applied to a device for uniformly oiling a tow, comprises the following steps: Step 1: Oiling process: The yarn tow is transferred from top to bottom. Under the joint positioning of the upper wire guide hook and the lower restraint assembly, the yarn tow is prevented from vibrating and deflecting significantly, ensuring that the yarn tow is fully in contact with the oil agent protruding from the oil port, thus completing the oiling work; Step 2: The gathering process. During the oiling process, the constraint component drives the silk thread to deviate to one side, while the gathering component drives the oil on the same side to gather and move to the silk bundle. Then the direction changes, and the constraint component drives the silk bundle to cooperate with the gathering component to oil again on the other side, consuming the oil that has deviated on both sides. During this process, the pushing component collects the falling oil in time, and a part of it is transported to both sides of the oil port by the compensation component. Step 3: Avoidance process. When foam appears at the oil port, the visual monitoring device immediately activates the avoidance component through an electrical signal to shift the tow outward, and oils the tow through the collection component and the oil replenishment component to ensure that the oiling work is carried out normally. Step 4, defoaming process, when the avoidance component moves, it drives the defoaming component into working state, and cooperates with the gathering component to deliver a small amount of defoaming agent to the oil port position to eliminate foam in time.

[0015] The beneficial effects of the present invention are: (1) The present invention provides a process for uniformly oiling the tow, which can effectively solve the problem of uneven oiling caused by the tow's own vibration during transmission and the problem of needing to stop the machine for maintenance every time foam is eliminated, thereby greatly improving the quality and output of the product.

[0016] (2) The present invention sets a constraint component and a gathering component to cooperate with each other, so that the oil that originally diffused and flowed to both sides due to the shaking of the filament bundle can be used again for oiling work. On the one hand, the utilization rate of the oil is timely improved, and the pressure for subsequent oil recovery, filtration and other operations is reduced. On the other hand, since the oil output rate at the center position of the oil port is stable, after the oil is dispersed by the filament bundle, the protruding distance of the oil at the center position is reduced. At this time, by consuming the oil diffused on both sides and then accumulating the oil at the center position, it is beneficial to ensure the stable progress of the oiling work.

[0017] (3) The present invention provides an oil replenishing component and an avoidance component, so that once a foam problem occurs at the oil port position, the yarn bundle can be quickly moved out of the oil port position to avoid foam adhering to the yarn bundle and forming oil spots, and the yarn bundle can be replenished with oil from below in time to ensure the continuous progress of the oiling work and improve production efficiency.

[0018] (4) The present invention sets a defoaming component, and after the filament bundle is removed, cooperates with the gathering component to add a small amount of defoaming agent at the top of the oil port, and then diffuses downward along the oil agent to quickly eliminate the foam, which ensures that the foam will not diffuse to the filament bundle position and affect the appearance of the filament bundle, and also maintains the production process.

[0019] In summary, the present invention has the advantages of good tow oiling effect, high production efficiency, and full utilization of oil. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0023] Example 1 like Figures 1 to 6 As shown, this embodiment provides a device for uniformly oiling a tow, comprising a plurality of oil nozzles 200 disposed on a spinning chamber 100 and an oil port 300 disposed on the oil nozzles 200, and further comprising: The oiling mechanism 1 is provided on the oil nozzle 200 and is used to maintain a stable oiling process of the tow; An emergency treatment mechanism 2 is provided on the oil nozzle 200 and is used to transfer the tow when foam is generated at the oil port 300 and ensure that the oiling of the tow is carried out normally; The oiling mechanism 1 includes a constraint component 11 arranged on the spinning chamber 100 and used to assist the yarn bundle in reducing jitter and deviation, a gathering component 12 arranged on the oil nozzle 200 and located below the constraint component 11 and used to gather the oils on both sides, a compensation component 13 arranged inside the oil nozzle 200 and used to drive part of the oil back to the working position of the gathering component 12, and a pushing component 14 arranged on the gathering component 12 and used to drive the rapid recovery of the oil.

[0024] In this embodiment, by setting up an oiling mechanism 1 in conjunction with the emergency treatment mechanism 2, the functions of stable contact between the yarn bundle and the oil agent and timely elimination of foam and resumption of production are achieved, which solves the technical problems of the yarn bundle jumping at the oil nozzle 200 position, the oil agent being easily driven to diffuse to both sides, and the unstable contact state between the yarn bundle and the oil agent. At the same time, due to the high temperature of the oil agent or the mixing of air, foam appears at the oil port 300 position, affecting the appearance of the yarn bundle and the quality of the textile.

[0025] In detail, first, the filament bundle continuously shakes at the oil port 300 during the top-down transmission process, causing the oil at the oil port 300 to move and diffuse to both sides, thereby causing the protrusion of the oil at the oil position on the wire to be unstable. At this time, the constraint component 11 cooperates with the gathering component 12 to move the filament bundle to one side and gather the oil diffused on the same side, thereby making a part of the oil consumed by the filament bundle come from the parts diffused on both sides, and the oil at the center oil port 300 returns to a normal level, thereby dynamically maintaining the stability of the entire oiling work. In addition, the pushing component 14 collects the falling oil in time to prevent it from being contaminated by long contact with the air. A part of the collected oil will be used by the compensation component 13 on both sides of the oil port 300 to prevent the situation where there is insufficient oil on the same side of the wire after the offset.

[0026] Further, if Figures 1 to 4 As shown, the constraint assembly 11 includes a first driving cylinder 111 connected to the spinning chamber 100, a driving plate 112 connected to the output end of the first driving cylinder 111, two groups of rotating shafts 113 connected to the driving plate 112 and symmetrically arranged on both sides of the filament bundle, a regulating wheel 114 connected to the end of the rotating shaft 113, transmission gears 115 respectively connected to the corresponding rotating shafts 113 and meshing with each other, and a first motor 116 connected to the driving plate 112 and with the output end connected to the corresponding rotating shaft 113.

[0027] In this embodiment, by setting two groups of regulating wheels 114 with grooves in the constraint component 11, cooperating with the avoidance tube 233 in the avoidance component 23, the filament bundle is controlled in a specified area to prevent it from jumping over a large range, and when the filament bundle is driven to one side, it can be kept in the middle position under the guidance of the grooves on the regulating wheel 114, ensuring the stability of oiling when the filament bundle is offset. In addition, the rotation speed of the regulating wheel 114 is set corresponding to the transmission speed of the filament bundle, thereby reducing the friction between the filament bundle and the regulating wheel 114.

[0028] In detail, first, the first motor 116 drives the two sets of regulating wheels 114 to rotate through the rotating shaft 113 and the transmission gear 115, and then the first driving cylinder 111 extends through the output end to drive the driving plate 112 to move. At this time, the rotating shaft 113 connected to the driving plate 112 drives the two sets of regulating wheels 114 to move to one side, and then the regulating wheel 114 on the rear side along the moving direction squeezes and pushes the filament bundle to deviate to one side, and then leaves the position in the axial direction of the oil port 300.

[0029] Further, if Figures 2 to 6 As shown, the gathering assembly 12 includes an active rack 121 whose two ends are respectively connected to two groups of rotating shafts 113, a follower rack 122 connected to the oil nozzle 200, a follower gear 123 connected to the oil nozzle 200 and respectively engaged with the active rack 121 and the follower rack 122 for transmission, and two groups of gathering plates 124 connected to the oil nozzle 200 and respectively connected to the two ends of the follower rack 122.

[0030] In this embodiment, by providing a gathering component 12 that cooperates with the constraint component 11, the oil that originally diffused and flowed to both sides due to the shaking of the filament bundle can be used again for oiling work. On the one hand, the utilization rate of the oil is timely improved, and the pressure for subsequent oil recovery, filtration and other operations is reduced. On the other hand, since the oil output rate at the center position of the oil port 300 is stable, after the oil is dispersed by the filament bundle, the protruding distance of the oil at the center position is reduced. At this time, by consuming the oil diffused on both sides and accumulating the oil at the center position, it is beneficial to ensure the stable progress of the oiling work.

[0031] In detail, when the regulating wheel 114 squeezes and pushes the filament bundle to deviate to one side, the active rack 121 connected to the rotating rod also moves accordingly, and drives the two sets of gathering plates to move in the opposite direction of the movement of the driving plate 112 through the follower gear 123 and the follower rack 122, so that when the filament bundle deviates to one side, the gathering plate on the same side drives the diffused oil agent to move toward the filament bundle, and when the first driving cylinder 111 contracts, the same action is completed on the other side.

[0032] Further, if Figures 2 to 6As shown, the compensation component 13 includes an oil groove 130 opened on the oil nozzle 200 and located below the oil port 300, a compensation channel 131 opened on the oil nozzle 200 and connected to the oil groove 130, a dragon screw 132 connected to the compensation channel 131, a second motor 133 connected to the oil nozzle 200 and whose output end is connected to the dragon screw 132, a delivery pipe 134 connected to the compensation channel 131 and with two groups of outlets located on both sides of the oil port 300, a U-shaped rod 135 connected to the gathering plate 124, and a blocking block 137 connected to the U-shaped rod 135 through a first telescopic member 136 and used to close the delivery pipe 134.

[0033] In this embodiment, a portion of the collected oil is returned to both sides of the oil port 300 by providing a compensation component 13, thereby preventing the filament bundle from shaking unstably and causing less diffusion of oil on one side, which affects the uniform oiling. In addition, in conjunction with the movement of the gathering component 12, the outlet on the same side of the filament bundle can be closed, which can prevent the leakage of oil between the contact surface between the gathering plate and the oil nozzle 200 on the one hand, and ensure sufficient oil in the offset direction of the filament bundle when it is offset next time on the other hand.

[0034] In detail, in order to ensure that there is no contact friction between the tow and the oil nozzle 200, the oil at the oil port 300 will form a certain protrusion height. During the oiling process, the oil also flows downward with the traction and enters the oil tank 130 for collection. Part of the collected oil flows into the compensation channel 131, and then the second motor 133 drives the dragon screw 132 to rotate, and the oil is delivered to both sides of the oil port 300 through the delivery pipe 134. In addition, when the gathering plate moves, it drives the U-shaped rod 135 to move, and the first telescopic member 136 connected to the U-shaped rod 135 drives the blocking block 137 to close the delivery pipe 134 on the same side, and the delivery pipe 134 on the other side is in an open state, thereby completing the alternating replenishment of the two sides.

[0035] It should be noted that the contact position between the delivery tube 134 and the blocking block 137 is an elastic hose.

[0036] Further, if Figure 2 and Figures 4 to 6 As shown, the pushing assembly 14 includes a guide plate 141 connected to the gathering plate 124, a first scraper 142 connected to the gathering plate 124 and fitting with the top inclined surface of the oil tank 130, and a second scraper 144 connected to the bottom of the gathering plate 124 through a second telescopic member 143 and fitting with the inclined surfaces on both sides of the oil tank 130.

[0037] In this embodiment, the pushing component 14 is provided to timely push the oil agent flowing down over a large area for centralized collection, thereby reducing the contact area and contact time between the oil agent and the air, ensuring that the oil agent is not contaminated, and reducing the workload of filtering treatment during subsequent recovery and storage.

[0038] In detail, when the gathering plate 124 on one side moves toward the oil port 300, the oil gathers on one side. When oiling, the oil begins to move downward and is guided into the oil tank 130 by the guide plate 141. During the movement, the first scraper 142 at the bottom of the gathering plate scrapes the top inclined surface of the oil tank 130, causing the upper oil to fall to the lower inclined surface. Subsequently, with the cooperation of the second scraper 144 and the second telescopic member 143, the oil on the lower inclined surface is pushed to the middle position for centralized collection.

[0039] It should be noted that the pushing component 14 performs collection work at the positions on both sides of the oil port 300 because the oil flow rate on both sides is small and flows slowly, and the pushing component 14 is reduced to be close to the center to prevent the tow from coming into contact with it, resulting in burrs.

[0040] Further, if Figures 2 to 3 and Figures 6 to 10 As shown, the emergency treatment mechanism 2 includes a collecting component 21 arranged on the oil nozzle 200 and used to collect excess oil, an oil replenishing component 22 arranged inside the oil nozzle 200 and used to cooperate with the collecting component 21 to oil the filament bundle, an avoidance component 23 arranged on the oil nozzle 200 and used to cover the collecting component 21 to prevent the collected oil from contacting with the air for a long time, and a defoaming component 24 arranged on the gathering component 12 and used to eliminate foam.

[0041] In this embodiment, by setting up the emergency treatment mechanism 2, the device can make rapid adjustments in extreme cases of foam generation, ensuring production while preventing the large-scale generation of tows with oil spots, thereby improving production efficiency and ensuring production quality.

[0042] In detail, when the visual monitoring device recognizes that foam is generated, the avoidance component 23 quickly drives the filament bundle away from the oil port 300 position, and at the same time the oil replenishment component 22 uses the oil collected by the collection component 21 for the oiling work to ensure that the oiling work is continued. At the same time, the avoidance component 23 drives the defoaming component 24 to be in a working state, and cooperates with the aggregation component 12 to add a small amount of defoaming agent to the oil from above the oil port 300 to eliminate foam.

[0043] It should be noted that the visual monitoring device is an existing technology and will not be described in detail here. When the defoaming component 24 is working, the staff will quickly analyze the situation. If the foam disappears in time, the avoidance component 23 can be controlled to reset, and the yarn bundle transported during the reset process can be manually oiled to ensure that there is no break on the oil surface of the yarn bundle. Then the device maintains normal operation. If foam continues to be generated, it means that the source of the foam is not air mixing or a sudden change in the oil temperature, but from damage to the device or a major problem with the airtightness. At this time, it is necessary to stop the machine for investigation.

[0044] Further, if Figures 2 to 3 and Figures 6 and 7As shown, the collecting assembly 21 includes a collecting chamber 211 opened on the oil nozzle 200, a collecting channel 212 provided on the oil nozzle 200 and connected to the oil tank 130, and a collecting tank 213 provided in the collecting chamber 211 and located below the collecting channel 212; The oil replenishing assembly 22 includes a round rod 222 connected to the oil nozzle 200 through a slider 221, a third motor 223 connected to the slider 221 and having its output end connected to the round rod 222, an oil wheel 224 connected to the round rod 222, a regulating frame 225 passing through the oil nozzle 200 and connected to the round rod 222, and a second driving cylinder 226 connected to the spinning chamber 100 and having its output end connected to the regulating frame 225.

[0045] In this embodiment, by providing an oil replenishing assembly 22, the tow is replenished with oil from below in a timely manner, thereby ensuring the continuous progress of the oiling work, improving production efficiency, and reducing downtime problems.

[0046] In detail, most of the oil in the oil tank 130 flows into the collecting tank 213 through the collecting channel 212 for collection, and is then collected and processed by pumping. When foam appears at the oil port 300, the second driving cylinder 226 quickly drives the avoidance component 23 to move the tow away from the oil port 300, and then drives the round rod 222 and the oil tanker 224 to move to the contact position with the tow through the regulating frame 225. The collecting channel 212 is also located above the oil tanker 224. At this time, driven by the third motor 223, the oil tanker 224 directly uses the oil flowing down the collecting channel 212 for oiling the tow.

[0047] It should be noted that the lower end of the collecting channel 212 is a pipe made of flexible material, which facilitates the movement of the oil tanker 224 and prevents the oil from splashing when it falls on the oil tanker 224.

[0048] Further, if Figures 2 to 4 and Figures 7 and 8 As shown, the avoidance assembly 23 includes a cooperative frame 232 connected to the output end of the second driving cylinder 226 through a third telescopic member 231, a plurality of avoidance tubes 233 connected to the cooperative frame 232, two groups of guide rail frames 234 connected to the oil nozzle 200 and connected to the round rod 222, a door panel 235 connected to the guide rail frame 234 and used to close the collection chamber 211, a first gear 236 connected to the guide rail frame 234, and a first rack 237 respectively connected to the collection chamber 211 and the door panel 235 and meshing with the first gear 236 for transmission.

[0049] It is worth mentioning here that by setting the avoidance component 23, the filament bundle can be quickly moved out of the oil port 300 position once a foam problem occurs, so as to avoid foam adhering to the filament bundle and forming oil spots. At the same time, the door panel 235 of the collection chamber 211 not only plays a sealing role, but also maintains a certain distance from the filament bundle when unfolded to prevent contact and friction.

[0050] In detail, when the output end of the second driving cylinder 226 extends, the cooperative frame 232 is driven to slide on the oil nozzle 200 through the third telescopic member 231, and the fiber bundle is moved away from the oil port 300 through the avoidance tube 233. Then the cooperative frame 232 is limited by the oil nozzle 200 and no longer moves. As the output end of the second driving cylinder 226 continues to extend, the third telescopic member 231 contracts, and the oil replenishing assembly 22 is in place. During this process, the round rod 222 drives the guide frame 234 to move. After the door panel 235 moves out of the collecting chamber 211, the first gear 236 connected to the guide frame 234 engages with the first rack 237 on the inner wall of the collecting chamber 211 for transmission, and then drives the door panel 235 to open to one side through the first rack 237 on the door panel 235 to avoid the fiber bundle.

[0051] It should be noted that the avoidance tube 233 is hollow and can rotate freely, thereby reducing the temperature of the filament bundle friction by passing coolant.

[0052] Example 2 like Figure 6 and Figures 9 and 10 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: like Figure 6 and Figures 9 and 10 As shown, the defoaming assembly 24 includes a trigger plate 241 connected to the top of the gathering plate 124, a second rack 242 connected to the bottom of the trigger plate 241, a screw rod 243 connected to the inside of the gathering plate 124, a second gear 244 connected to the screw rod 243 and meshing with the second rack 242 for transmission, a slide 245 connected to the inside of the gathering plate 124, a moving block 246 connected to the screw rod 243 and located inside the slide 245, and a moving block 246 connected to the moving block 246 and passing through the moving block 245. A conveying rod 247 passing through the gathering plate 124, a storage groove 248 opened on the conveying rod 247, a feeding bin 249 connected to the inside of the gathering plate 124, a T-rod 2411 passing through the conveying rod 247 and the moving block 246 and connected to the moving block 246 through a spring 2410, a valve plate 2412 connected to the end of the T-rod 2411 and located in the storage groove 248, and a protrusion 2413 connected to the slide 245 and used to block the T-rod 2411.

[0053] In this embodiment, a defoaming component 24 is provided, and after the filament bundle is removed, a small amount of defoaming agent is added to the top of the oil port 300 in conjunction with the gathering component 12, and then diffuses downward along the oil agent to quickly eliminate the foam, thereby ensuring that the foam will not diffuse to the filament bundle position and affect the appearance of the filament bundle, and also maintaining the production process.

[0054] In detail, when the rear avoidance tube 233 moves, it drives the trigger block on the top of the gathering plate to move, and the trigger block drives the second gear 244 to rotate through the second rack 242, thereby causing the screw rod 243 to rotate, and then the moving block 246 connected to the screw rod 243 moves in the slide 245, pushing the delivery rod 247 outward, and at the same time the gathering assembly 12 moves the gathering plate with the defoaming agent to the oil port 300 position. When the delivery rod 247 is fully extended, it is just above the oil port 300, and because the protrusion 2413 blocks the T-rod 2411, the T-rod 2411 drives the valve plate 2412 to open, and the defoaming agent falls from the storage tank 248 into the oil agent.

[0055] It should be noted that the two sides of the feed bin 249 can be used alternately, and only one side is used each time foam appears, thereby reducing the amount used. The amount of defoaming agent used needs to be strictly controlled, and adding too much can easily affect the performance of the tow.

[0056] Example 3 like Figure 11 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The differences between the third embodiment and the first embodiment are: like Figure 11 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that: A process for uniformly oiling a tow, applied to a device for uniformly oiling a tow, comprises the following steps: Step 1: Oiling process: The yarn tow is transferred from top to bottom. Under the joint positioning of the upper wire guide hook and the lower restraint assembly 11, the yarn tow is prevented from vibrating and deviating significantly, ensuring that the yarn tow is fully in contact with the oil agent protruding from the oil port 300, thus completing the oiling work; Step 2, the gathering process: during the oiling process, the constraint component 11 drives the silk thread to deviate to one side, while the gathering component 12 drives the oil on the same side to gather and move toward the silk bundle. Then the direction changes, and the constraint component 11 drives the silk bundle to cooperate with the gathering component 12 to oil again on the other side, consuming the oil that has deviated on both sides. During this process, the pushing component 14 collects the falling oil in time, and a part of it is delivered to both sides of the oil port 300 by the compensation component 13; Step 3: Avoidance process. When foam appears at the oil port 300, the visual monitoring device immediately activates the avoidance component 23 through an electrical signal to deflect the tow outward, and oils the tow through the collection component 21 and the oil replenishment component 22 to ensure that the oiling process is carried out normally. Step 4, defoaming process, when the avoidance component 23 moves, it drives the defoaming component 24 to enter the working state, and cooperates with the gathering component to deliver a small amount of defoaming agent to the oil port 300 position to eliminate foam in time.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
