Description

Technical Field

[0001] This utility model relates to the field of spinning oil extraction technology, and in particular to a pre-network oil extraction and recovery device for modified polyamide 6 filament bundles. Background Technology

[0002] The pre-network suction device is used to blow away excess oil droplets adhering to the yarn after texturing and networking, so as to avoid the excess oil droplets affecting the yarn process.

[0003] In existing pre-network suction devices, the suction force is large, and the suction port is directly connected to the negative pressure device. In particular, the airflow is uneven, resulting in uneven oil absorption. In addition, waste fibers are also sucked into the fume duct. This results in a large amount of impurities in the recovered oil mist, which cannot be processed directly and needs to be filtered before it can be recycled again. Moreover, waste fibers will adhere to the inside of the pipe, and long-term accumulation will block the airflow in the pipe, causing poor oil mist suction. All of these factors will result in the oil on the fibers not being completely sucked out, affecting the quality of subsequent processes.

[0004] Especially in the spinning process of modified polyamide 6 yarn, this yarn has a high absorption rate of oiling agent. The large amount of oiling agent absorbed can cause abnormalities in the subsequent spinning process. In particular, the large amount of oil mist and oil droplets during the subsequent winding process can cause slippage and affect the subsequent processes.

[0005] Based on this, this utility model designs a pre-networked oil suction and recovery device for modified polyamide 6 filament bundles to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a pre-network oil suction and recovery device for modified polyamide 6 filament bundles. This device optimizes oil suction, especially by isolating impurities and allowing for easy manual cleaning of waste filaments to ensure unobstructed flow through the mesh. The absorbed oil is blocked by the mesh and air filter, allowing it to flow into the oil collection tank for convenient recovery. A baffle is also installed at the filament bundle turning point to intercept oil droplets thrown out during turning, which can then be collected and recovered via a guide bucket. The device is easy to use, and the thrown-out oil droplets do not affect the filament's movement or pulling, effectively ensuring the quality of the filament bundle.

[0007] This invention is achieved as follows: a pre-networked oil suction and recovery device for modified polyamide 6 filament bundles, comprising: Suction hood, wire drawing roller, oil collection trough and suction box; The suction box is a closed box, and a guide box is provided at the bottom of the suction box. The suction box and the guide box are an integral structure that are interconnected. A guide is provided inside the suction box, and the guide groove of the guide is vertically arranged. The suction hood has a funnel-shaped structure that is wider inside and narrower outside. The left end of the suction hood is connected to a negative pressure tube, and the right end of the suction hood is covered with a mesh, which is a vertically arranged mesh plate. A flow guide plate is provided at the bottom of the suction hood. The flow guide plate is a baffle that slopes inward at the bottom and is located directly below the mesh. The oil collection trough is a long strip-shaped water trough with an open top. The oil collection trough is arranged in the front-to-back direction and is located directly below the bottom edge of the guide plate. The drawing roller is a roller that pulls the yarn forward. Multiple drawing rollers are horizontally arranged in the yarn guide box. Anti-splash plates are arranged between adjacent drawing rollers on the left and right, and liquid baffles are arranged between adjacent drawing rollers on the top and bottom. The bottom of the guide wire box is equipped with a flow guide funnel, which is a funnel-shaped structure that is wider at the top and narrower at the bottom. The lower opening of the flow guide funnel is a drain outlet.

[0008] Furthermore, the inner opening of the suction hood and the partition mesh are both within the receiving range of the guide plate.

[0009] Furthermore, the front end of the oil collection trough is also connected to an oil drain pipe. The oil collection trough is inclined in the front-to-back direction. The end of the oil collection trough connected to the oil drain pipe is lower than its rear end. The bottom edge of the guide plate extends into the oil collection trough, and the oil collection trough and the guide plate do not contact each other. Furthermore, the oil collection trough is located directly below the bottom edge of the guide plate; The oil drain pipe does not contact the silk thread or the drawing roller; The oil drain pipe and the oil collection trough are both located inside the suction box.

[0010] Furthermore, both the splash guard and the liquid baffle are made of thin stainless steel sheets; The back of the splash guard is connected to the wire guide box. The splash guard blocks the wire turning point of the front wire drawing roller. The splash guard is a curved thin plate with a lower right side and a higher left side. The bottom edge of the splash guard is outside the range of the wire drawing roller. The baffle plate blocks the turning point of the yarn on the upper drawing roller. The left side of the baffle plate is fixedly connected to the inner wall of the guide box. Multiple liquid guiding holes are opened on one side edge of the baffle plate. Each liquid guiding hole is spaced at the same interval. The liquid guiding hole is a semi-circular hole with an edge opening. The opening side of the liquid guiding hole is in contact with the inner wall of the guide box.

[0011] Furthermore, an air mesh is provided between the negative pressure pipe and the outer port of the suction hood. The air mesh is a vertically arranged fence-like structure, and the bottom of the air mesh is directly above the inclined side wall of the suction hood.

[0012] The beneficial effects of this utility model are: 1. This utility model adds a partition screen and a wind screen. The partition screen filters impurities in the suction box and disperses the airflow in the negative pressure pipe, making the negative pressure suction more uniform. It effectively prevents waste wire from entering the negative pressure pipe and ensures the smooth flow of the pipe. More importantly, the partition screen is particularly easy to clean. It can be removed manually without stopping the machine. The wind screen can also block the oil again and intercept the oil mist, so that the oil droplets are blocked as much as possible, effectively reducing the total amount of oil droplets entering the negative pressure pipe. 2. The guide box of this device is equipped with a splash guard and a liquid baffle, which can block the oil droplets thrown out by the high-speed traveling wire when it turns, so as to prevent the oil droplets from splashing and affecting each other when the wire is traveling. The splash guard and liquid baffle can also guide the oil droplets to be discharged outside the guide box for collection. Attached Figure Description

Detailed Implementation

[0016] Please see Figures 1 to 3 As shown, this utility model provides a pre-networked oil suction and recovery device for modified polyamide 6 filament bundles. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.

[0017] In a specific embodiment of the technical solution of this utility model: Includes suction hood 1, wire drawing roller 2, oil collection trough 3, and suction box 4; The suction box 4 is a closed box. A guide wire box 41 is set at the bottom of the suction box 4. The suction box 4 and the guide wire box 41 are an integral structure that are interconnected. The suction box 4 and the guide wire box 41 form an L-shaped hollow box. A guide wire device 42 is set inside the suction box 4. The guide wire groove of the guide wire device 42 is set vertically, which allows the wire to travel vertically from top to bottom. It also allows the wire traveling in the guide wire device 42 to form a parallel state with the mesh 11. Furthermore, it allows the wire to spread out in parallel, which is convenient for the suction of oil fumes. The function of the guide wire device 42 is to guide the wire, change the direction of the wire, and spread out the wire to avoid contact and interference with other structures. The suction hood 1 has a funnel-shaped structure that is wider inside and narrower outside, that is, as shown in the image. Figure 1 The suction hood 1 has a narrow left and wide right constriction-shaped structure. The left end of the suction hood 1 is connected to the negative pressure pipe 14. A wind net 12 is also provided between the negative pressure pipe 14 and the outer port of the suction hood 1. The wind net 12 is a vertically arranged grid-like structure. The bottom of the wind net 12 is directly above the inclined side wall of the suction hood 1. The wind net 12 is inside the suction hood 1, so that the oil mist drawn in by the strong suction negative pressure can condense on the inner wind net 12. This allows the oil droplets to flow down the wind net 12 to the inclined side wall of the suction hood 1, and then flow down the inclined surface of the side wall of the suction hood 1 into the guide plate 13 and the oil collection groove 3.

[0018] The right end of the suction hood 1 is covered by a mesh 11, which is a vertically set mesh plate. The mesh 11 can block waste filaments and other impurities. It only needs to be cleaned regularly. Moreover, it is not necessary to disassemble the mesh 11 during cleaning because the impurities are basically not other substances, but waste filaments. The waste filaments are continuous long filaments. You only need to pull the waste filaments away from the mesh 11 by hand. The operation is simple. A guide plate 13 is provided at the bottom of the suction hood 1. The guide plate 13 is a baffle that slopes inward at the bottom and is located directly below the partition screen 11. The inner opening of the suction hood 1 and the partition screen 11 are both within the receiving range of the guide plate 13, thereby guiding and collecting the oil.

[0019] The oil collection trough 3 is a long strip-shaped water trough with an open top, and the oil collection trough 3 is located directly below the bottom edge of the guide plate 13, which facilitates the collection and discharge of oil from the guide plate 13. The oil collection trough 3 is inclined in the front-to-back direction. An oil drain pipe 33 is also provided at the front end of the oil collection trough 3. The end of the oil collection trough 3 connected to the oil drain pipe 33 is lower than its rear end. The bottom edge of the guide plate 13 extends into the oil collection trough 3, and the oil collection trough 3 and the guide plate 13 do not contact each other.

[0020] The outlet of the oil drain pipe 33 is located directly above the guide bucket 31, and the oil drain pipe 33 does not contact the silk thread or the drawing roller 2. Both the oil drain pipe 33 and the oil collection trough 3 are located inside the suction box 4. The drawing roller 2 is a roller that pulls the yarn forward. The drawing roller 2 is a common structure for changing the direction of the yarn. Multiple drawing rollers 2 are horizontally arranged in the yarn guide box 41. A splash guard 21 is set between adjacent left and right drawing rollers 2, and a liquid baffle 22 is set between adjacent upper and lower drawing rollers 2. The bottom of the guide box 41 is provided with a guide bucket 31, which is a funnel-shaped structure that is wider at the top and narrower at the bottom. The lower opening of the guide bucket 31 is the drain port 32.

[0021] Both the splash guard 21 and the liquid baffle 22 are made of thin stainless steel sheets; The back of the anti-splash plate 21 is connected to the wire guide box 41. The anti-splash plate 21 blocks the wire turning point of the front wire drawing roller 2, which is the oil ejection path of the front wire drawing roller 2. The anti-splash plate 21 is a curved thin plate with a lower right side and a higher left side. The bottom edge of the anti-splash plate 21 is outside the range of the wire drawing roller 2. The baffle plate 22 blocks the oil at the turning point of the upper drawing roller 2, which is the path where the oil is thrown out of the lower drawing roller after the yarn turns. This prevents the oil from interfering with each other when it is thrown out between the yarns, effectively preventing the yarn from being affected by the front drawing roller 2. The oil is mainly thrown out where the centrifugal force is greater at the turning point of the drawing roller 2. As the yarn turns, the oil continues to move due to inertia, causing excess oil adhering to the yarn to be thrown out. This device uses multiple drawing rollers 2 to turn the yarn, thereby throwing out the excess oil. The thrown-out oil is basically blocked by the splash plate 21 and the baffle plate 22 and flows out along the yarn guide box 41, ensuring that the thrown-out excess oil does not affect the subsequent yarn. The baffle plate 22 The left side of the baffle plate 22 is fixedly connected to the inner wall of the wire guide box 41. The baffle plate 22 is lower on the left and higher on the right, and lower in the front and higher in the back, forming an inclined flat plate. The wire travels relatively close to the back plate of the wire guide box 41. Therefore, the oil droplet guide on the front side can effectively guide the oil away and prevent the oil droplets from contacting the wire. Multiple guide holes 23 are opened on one side edge of the baffle plate 22. Each guide hole 23 is spaced at the same interval. The guide hole 23 is a semi-circular hole with an edge opening. The opening side of the guide hole 23 is in contact with the inner wall of the wire guide box 41. The guide hole 23 forms a closed semi-circular hole through the wire guide box 41. In this way, the oil droplets intercepted by the baffle plate 22 will flow away along the guide hole 23 and be recycled and treated, preventing the oil droplets from accumulating and dripping onto the wire.

[0022] In use, the yarn enters the suction box 4 from top to bottom. The yarn is guided and pulled by the yarn guide 43. The suction force of the negative pressure pipe 14 is transmitted in the suction box 4. The strong suction force will draw in the oil mist and disperse it evenly through the partition 11. It can also block broken or floating yarn. After several days of blocking, the yarn will accumulate on the partition 11. The yarn blocked by the partition 11 can be taken out according to the actual spinning state. Since the front of the suction box 4 and the yarn guide box 41 also has a door with the same structure as the cabinet door, it can be flipped open directly. The broken yarn can be easily taken out directly. The whole process does not require stopping the machine and can be done manually.

[0023] The intercepted oil will be guided downward by the partition 11, and will continue to drip into the oil collection tank 3 through the guide plate 13. Then it will be discharged into the guide bucket 31 through the oil discharge pipe 33, and then collected and processed together through the drain port 32.

[0024] The thread will continue to travel downwards, and will be guided and turned within the guide box 41, such as... Figure 1 As shown, the yarn will repeatedly turn on multiple drawing rollers 2. Each time it turns, the oil on the yarn will be squeezed and thrown out by high-speed centrifugal force. At the same time, it will be blocked by the splash plate 21 and the baffle plate 22, and the oil will be guided back to be collected on the guide bucket 31.

[0025] The splash guard 21 is higher on the left and lower on the right, causing the blocked oil to drip to the right and flow downwards to drip outside the path of the thread, effectively preventing the thread from contacting the oil droplets.

[0026] The baffle plate 22 is connected to the left side where the wire leaves, which is the opening of the wire guide box 41. The wire will flow forward along the baffle plate 22 and simultaneously flow towards the inner wall of the wire guide box 41 on the left side, and then flow away along the inner wall of the wire guide box 41.

[0027] The suction box 4 and guide wire box 41 referred to in this device are inside the boxes, while the negative pressure pipe 14 is inside the pipe. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the attached drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.
