Description

Technical Field

[0001] The present invention relates to the technical field of spinning, and in particular to a nylon elastic composite fiber spinning device and a use method thereof. Background Art

[0002] Spinning equipment is mechanical equipment used to convert polymer raw materials into fibers. It mainly includes melt spinning equipment, wet spinning equipment, dry spinning equipment and electrospinning equipment. Among them, melt spinning equipment is widely used due to its advantages of environmental protection, high efficiency and low cost.

[0003] In the process of preparing high-elastic nylon fiber (hereinafter referred to as elastic fiber) using a melt spinning machine, it is necessary to spin nylon 6 elastomer and PA6 polymers in parallel, and utilize the difference in thermal shrinkage of the two components during the composite spinning process to obtain high-elastic nylon fiber. The specific operation is: heating the two raw materials to a molten state in the barrel of the melt spinning machine, and then extruding the above two raw materials downward together. The two raw materials pass through the distribution plate and enter the spinneret together, and finally obtain high-elastic nylon fiber through the spinneret. After the molten raw materials are extruded into elastic fibers through the spinneret, air cooling is required to promote the cooling and shaping of the elastic fibers.

[0014] A method for using a nylon elastic composite fiber spinning device, based on the above-mentioned nylon elastic composite fiber spinning device, specifically comprises the following steps: S1: Add raw materials into the barrel, start the spinning machine, brushless motor and cooling element, and the raw materials in the barrel are ejected through the spinneret to form elastic fibers. At the same time, part of the raw materials splash into the inner side of the protective barrel and flow along the protective barrel to the upper side of the adjacent storage ring. The external gas is drawn into the threaded ring and the mounting element by the fan. When the gas flows in the mounting element, the concave filter intercepts the impurities contained in the gas. S2: The gas passes through the cooling element and exchanges heat with it to form cold air. The cold air enters the corresponding shunt tube through the gap between the mounting element and the shunt tube, and flows downward along the gap between the shunt tube and the adjacent protective tube to exchange heat with the elastic fiber. S3: The gas drives the power part to rotate while flowing along the mounting part.

The inner gear ring controls the extrusion part to squeeze the sponge ring through the triangular block, so that the water in the sponge ring is evenly distributed. S4: The inner gear ring rotates and releases the extrusion of the extrusion member, so that the extrusion member and the sponge ring are reset. Then the inner gear ring moves downward under the action of the guide groove, so that the knocking ball knocks the concave filter screen, and the impurities intercepted by the concave filter screen are shaken off. Then the gas entrains the impurities through the waste storage cavity and the sponge ring, and the impurities are intercepted in the sponge ring; S5: The inner gear ring moves upward and resets under the action of the guide groove, and the knocking ball moves upward and resets. After the raw materials in the barrel are completely squeezed out, the mounting parts are removed and the raw materials accumulated on the upper side of the storage ring are cleaned, and then the sponge ring is cleaned.

[0015] In summary, the present application includes at least one of the following beneficial technical effects: the present invention limits the distance between the diverter tube and the mounting member so that the circumferential air volume entering the diverter tube tends to be consistent, thereby providing a good cooling environment for the elastic fibers and ensuring the consistency of the quality of each elastic fiber.

[0016] The scraper scrapes off the condensate on the cooling element, thereby ensuring the heat exchange efficiency between the gas and the cooling element and improving the cooling effect on the elastic fiber.

[0017] The concave filter is used to filter impurities in the gas, thereby reducing the impact of impurities in the gas on the uncured elastic fibers. At the same time, the collision between the knocking ball and the concave filter is used at intervals to remove the impurities intercepted by the concave filter, thereby ensuring the filtering effect of the concave filter and further ensuring the quality of the elastic fibers.

DETAILED DESCRIPTION

[0020] Other features and advantages of the present invention will be described in the following description, and partly become obvious from the description, or be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures pointed out in the description and the drawings.

[0021] In the process of using air cooling to promote the cooling and shaping of elastic fibers, a row of fans are usually arranged in a position parallel to the elastic fibers, and heat exchange is performed with the elastic fibers through cold air approximately perpendicular to the elastic fibers. Since the holes on the spinneret are distributed in a ring shape, the above-mentioned air cooling method will cause different heat exchange efficiencies of the elastic fibers at different positions, resulting in differences in the quality of the final elastic fiber products.

[0022] Example 1: A nylon elastic composite fiber spinning device, please refer to Figure 1-Figure 6, including a spinning machine 1, on which a barrel 2 (for storing raw materials) is installed, a component box 3 is threadedly connected to the lower side of the barrel 2, a spinneret 4 is sealed and slidably connected to the upper and lower parts of the component box 3 (the spinning machine 1, the barrel 2, the component box 3 and the spinneret 4 are all existing devices, which are not shown in detail in the figure), the spinneret 4 is provided with holes distributed in concentric circles, and the holes are used to extrude the raw materials, a mounting member 5 is fixedly connected to the lower side of the spinneret 4, the mounting member 5 is "mushroom-shaped", a threaded ring 6 is threadedly connected to the lower side of the mounting member 5, a sealing ring is provided between the mounting member 5 and the threaded ring 6, a brushless motor 7 is installed in the threaded ring 6, a fan 8 is fixedly connected to the output shaft of the brushless motor 7, and a cooling member 9 is installed in the middle and lower part of the mounting member 5. (The cooling member 9 is an existing semiconductor refrigeration plate, and the surface of the cooling member 9 is provided with through holes for gas to pass through, which are not shown in the figure), the mounting member 5 is provided with upper through holes and lower through holes near the holes on the spinneret 4, the diameter of the upper through hole is smaller than the diameter of the lower through hole, and the lower through hole is fixedly connected with a diverter tube 10, and in the direction away from the central axis of the mounting member 5, the distance between the upper side surface of the diverter tube 10 and the adjacent upper through hole gradually increases, so as to make the gas flow rate at various points in the circumferential direction of the diverter tube 10 tend to be consistent, that is, to make the gas contacted by the elastic fiber in the circumferential direction tend to be consistent per unit time, so as to ensure the consistent cooling effect on the circumferential direction of the elastic fiber, and a cleaning component for ensuring the heat transfer efficiency of the cooling member 9 is provided in the middle part of the mounting member 5.

[0023] Please refer to Figure 3 and Figure 4 A protective tube 11 is fixedly connected to the upper through hole of the mounting member 5. The protective tube 11 is used to prevent the gas from entering the adjacent diverter tube 10 at a fast flow rate, which causes the elastic fibers just extruded by the spinneret 4 to deform. The protective tube 11 is located in the adjacent diverter tube 10, and there is a gap between the diverter tube 10 and the adjacent protective tube 11.

[0024] Please refer to Figure 5-Figure 7 The cleaning assembly includes a power member 12, and the upper part of the power member 12 is provided with annularly distributed fan blades. The power member 12 is arranged on the cooling member 9, and the cooling member 9 is upwardly convex and is used to guide the condensate thereon to flow toward the periphery. A support member 13 is fixedly connected to the middle and lower part of the mounting member 5. The power member 12 is provided with a scraper 14 rotatably connected to the lower side of the cooling member 9. The support member 13 and the cooling member 9 are both in contact with the scraper 14. The scraper 14 cannot move up and down due to the action of the support member 13 and the cooling member 9. An inclined surface is provided on the clockwise direction (the rotation perspective of this article is from top to bottom) of the upper side of the scraper 14 to guide the condensate on the cooling member 9 to flow along the scraper 14.

[0025] When preparing nylon elastic fiber, workers add nylon 6 elastomer and PA6 into the barrel 2, then install the barrel 2 to the corresponding position on the spinning machine 1, and start the spinning machine 1. The raw materials in the barrel 2 are heated to a molten state by the spinning machine 1, and then the raw materials in the barrel 2 are squeezed downward by passing high-pressure gas into the barrel 2, so that the raw materials pass through the spinneret 4 to form elastic fibers. The elastic fibers pass through the protective tube 11 and move downward. At this time, the workers start the brushless motor 7 and the cooling member 9. The output shaft of the brushless motor 7 drives the fan 8 to rotate and draws external gas into the threaded ring 6 and the mounting member 5. The gas passes through the cooling member 9 for heat exchange during the upward flow of the gas in the mounting member 5, so that the gas temperature is reduced to form cold air. Then the gas enters the upper part of the mounting member 5, and enters between the shunt tube 10 and the adjacent protective tube 11 through the gap between the mounting member 5 and the shunt tube 10 and is ejected downward. The vertically downward cold wind cools the elastic fibers while guiding the moving trajectory of the elastic fibers, thereby reducing the probability of the uncured elastic fibers in the inner and outer circles contacting and winding with each other.

[0026] In the process of external gas passing through the cooling member 9, due to the sudden drop in temperature, the water vapor contained in the gas condenses on the surface of the cooling member 9, resulting in a reduction in the subsequent contact area between the gas and the surface of the cooling member 9. The solution is as follows: in the process of the gas flowing upward in the mounting member 5, the gas drives the power member 12 to rotate clockwise (the rotation perspective in this article is from top to bottom), and the power member 12 drives the scraper 14 to rotate. The scraper 14 scrapes off the condensate on the lower side of the cooling member 9 and guides the condensate to flow along it through the inclined surface of the scraper 14 until the condensate flows to the outside of the support member 13. This reduces the area of ​​condensate on the cooling member 9, thereby ensuring the efficiency of heat exchange between the cooling member 9 and the external gas.

[0027] When the scraper 14 guides the condensate to the outside of the support 13, the condensate flows along the outside of the support 13 and finally falls on the upper side of the threaded ring 6. After the raw materials in the barrel 2 are completely squeezed out, the worker stops the brushless motor 7 and the cooling part 9, stops the spinning machine 1 at the same time, and removes the barrel 2 for cleaning. At the same time, the threaded ring 6 is rotated to disconnect the threaded ring 6 from the mounting part 5. At this time, the condensate accumulated on the threaded ring 6 is cleaned, and then the threaded ring 6 is reinstalled on the mounting part 5.

[0028] It should be noted that, only in the present embodiment, the setting relationship between the power member 12 and the cooling member 9 is a rotational connection, and the setting relationship between the power member 12 and the scraper 14 is a fixed connection. In subsequent embodiments, the relationship between the power member 12 and the cooling member 9 is a sliding and rotational connection, and the power member 12 and the scraper 14 are splined connections.

[0029] When using cold air to cool the elastic fiber, if there are impurities such as dust in the cold air, the impurities will come into contact with the uncured elastic fiber along with the cold air and be embedded in the elastic fiber, causing the elastic fiber to become dirty and deformed, thus affecting the quality of the finished elastic fiber.

[0030] Example 2: Based on Example 1, please refer to Figure 8-Figure 10 , and also includes a support ring 22, which is fixedly connected to the lower part of the mounting member 5, and the support ring 22 is located below the support member 13. The support ring 22 is fixedly connected with a concave filter screen 15, and the concave filter screen 15 is concave and is used to guide the gas flowing from bottom to top to diffuse to the surrounding area. The power member 12 is slidably connected to the middle part of the concave filter screen 15 up and down and is rotatably connected. The lower part of the power member 12 is provided with a cleaning mechanism for cleaning the concave filter screen 15.

[0031] Please refer to Figure 8-Figure 10 The cleaning mechanism includes four ring-shaped knocking balls 16, which are fixed to the lower part of the power member 12 through an elastic rod. The knocking balls 16 are matched with the concave filter screen 15 to make the concave filter screen 15 vibrate and shake off the impurities intercepted thereon. The power member 12 passes through the middle part of the concave filter screen 15 and is fixed with a lower blocking ring 17. The lower blocking ring 17 is sealingly and slidably connected to the threaded ring 6. A partition member 18 is fixedly connected to the lower part of the inner side of the support member 13. The partition member 18 is slidably connected to the power member 12. The partition member 18 is provided with symmetrically distributed semi-ring through holes. A magnetic ring 19 is fixedly connected to the lower side of the partition member 18. The knocking balls 16 are matched with the magnetic ring 19 by magnetic attraction. Initially, the knocking balls 16 are in contact with the magnetic ring 19. The power member 1 2 is fixed with a sealing member 20, which is sealed and matched with the two semi-ring through holes on the partition member 18. The sealing member 20 is located above the partition member 18. The lower side of the sealing member 20 is fixed with an upper sealing ring 21 through a bracket. The support member 13 and the support ring 22 are both sealed and slidably matched with the upper sealing ring 21. The mounting member 5, the threaded ring 6, the support member 13, the outer side of the lower sealing ring 17, the outer side of the upper sealing ring 21 and the support ring 22 cooperate to form a waste storage cavity 221. The lower sealing ring 17 and the upper sealing ring 21 are both sealed and matched with the waste storage cavity 221. The upper part of the support member 13 is provided with a plurality of square through holes distributed in an annular manner. The upper part of the outer side of the support member 13 is fixed with a sponge ring 23, and the inner side of the sponge ring 23 is in contact with the scraper 14.

[0032] Please refer to Figure 8-Figure 11 The middle upper and lower limit sliding connections of the mounting member 5 are provided with an extrusion member 24, a tension spring is fixedly connected between the upper side of the extrusion member 24 and the mounting member 5, the lower side of the extrusion member 24 is fixedly connected to the upper side of the sponge ring 23, the extrusion member 24 and the sponge ring 23 are extruded and matched, and are used to squeeze out the condensate accumulated in the sponge ring 23, and a power component for providing power to the striking ball 16 and the extrusion member 24 is provided in the mounting member 5.

[0033] Please refer to Figure 8-Figure 11 The power assembly includes a sliding frame 25, which is fixed to the upper part of the mounting member 5. The sliding frame 25 slides up and down and is rotatably connected to three annularly distributed intermediate gears 26. The intermediate gears 26 and the power member 12 are driven by gears. The intermediate gears 26 are extruded and matched with the power member 12. The annularly distributed intermediate gears 26 are meshed with an inner gear ring 27. A triangular block 28 is fixed to the right side of the inner gear ring 27. The triangular block 28 is extruded and matched with the upper side of the extrusion member 24. A limiting column 29 is fixed to the upper right part of the mounting member 5. A guide groove 291 is provided on the inner gear ring 27. The guide groove 291 consists of a lower horizontal portion, a vertical portion, an upper horizontal portion and an inclined portion. The limiting column 29 slides in a limited position in the guide groove 291. The power member 12 is slidably and rotatably connected to the cooling member 9, and the power member 12 is splined to the scraper 14.

[0034] When the brushless motor 7 and the cooling member 9 are started to cool the elastic fiber, the external gas first passes through the concave filter 15 during the flow along the mounting member 5. The concave filter 15 blocks the impurities entrained in the gas and reduces the content of impurities in the gas. Then the gas passes through the semi-annular through hole on the partition member 18 and contacts the cooling member 9. The concave filter 15 helps to improve the quality of the finished elastic fiber. Repeat Example 1, the gas drives the power member 12 to rotate, the power member 12 drives the scraper 14 to rotate, and guides the condensate on the cooling member 9 to contact the sponge ring 23 through the scraper 14 and be absorbed by the sponge ring 23. As the gas flows along the mounting member 5, the gas drives the power member 12 to rotate, and the power member 12 drives the inner gear ring 27 to rotate counterclockwise through the transfer gear 26. At the same time, the limit column 29 slides along the lower horizontal portion of the guide groove 291.

[0035] During the counterclockwise rotation of the inner gear ring 27, the inner gear ring 27 drives the triangular block 28 and the guide groove 291 to rotate. The triangular block 28 first contacts the extrusion piece 24 and gradually squeezes the extrusion piece 24 downward, stretching the tension spring adjacent to the extrusion piece 24, so that the extrusion piece 24 squeezes the sponge ring 23 downward, the volume of the sponge ring 23 is reduced, and the condensate accumulated in the sponge ring 23 flows along the outer side of the support piece 13 to the upper side of the threaded ring 6. At the same time, the remaining condensate in the sponge ring 23 is evenly distributed in the sponge ring 23. As the inner gear ring 27 rotates, the triangular block 28 gradually loses its squeezing of the extrusion piece 24. At this time, the extrusion piece 24 moves upward under the action of its adjacent tension spring, and at the same time, the extrusion piece 24 pulls the sponge ring 23 upward to restore the sponge ring 23 to its deformation.

[0036] After the sponge ring 23 recovers its shape, as the inner gear ring 27 continues to rotate, the limiting column 29 gradually contacts the vertical part of the guide groove 291. At this time, the inner gear ring 27 moves downward under the gravity of the parts above it, and the inner gear ring 27 drives the power member 12 to move downward through the transfer gear 26. The power member 12 drives the knocking ball 16, the lower blocking ring 17, the sealing member 20, and the upper blocking ring 21 to move downward. In this process, the knocking ball 16 is affected by the magnetic attraction, causing the elastic rod of the knocking ball 16 to bend and deform. As the power member 12 moves downward, the elastic force of the elastic rod of the knocking ball 16 overcomes the magnetic attraction between the knocking ball 16 and the magnetic ring 19. The rear knocking ball 16 moves downward rapidly under the resetting action of its adjacent elastic rod, and finally collides with the upper side of the concave filter 15, causing the concave filter 15 to vibrate and vibrate out the impurities intercepted therein. Before the knocking ball 16 contacts the concave filter 15, the power part 12 drives the lower sealing ring 17, the sealing part 20, and the upper sealing ring 21 to move downward, and the sealing part 20 gradually contacts the partition part 18 and seals the two semi-ring through holes on the partition part 18. At the same time, the lower sealing ring 17 and the upper sealing ring 21 both release the blockage of the waste storage chamber 221. At this time, the limit column 29 moves to the end of the vertical part of the guide groove 291 and moves along the upper horizontal part.

[0037] During the movement of the limiting column 29 along the upper horizontal portion of the guide groove 291, a portion of the gas flowing in the mounting member 5 carries the impurities shaken off the concave filter screen 15 and flows along the inclined surface of the concave filter screen 15 to the waste storage chamber 221, and another portion of the gas passes through the concave filter screen 15 and carries the impurities shaken off the concave filter screen 15 and flows along the lower side of the partition member 18 and the sealing member 20 to the waste storage chamber 221. The gas entering the waste storage chamber 221 eventually passes through the sponge ring 23. The sponge ring 23, combined with the residual condensate therein, intercepts the impurities in the gas, reduces the content of impurities in the gas, and completes the concave filter screen 15. The filter screen 15 is cleaned. After the limit post 29 moves to the end of the horizontal part of the guide groove 291, the limit post 29 moves along the inclined part of the guide groove 291 and moves the inner gear ring 27 upward. The inner gear ring 27 drives the power member 12 to move upward. At this time, the above-mentioned step of moving the power member 12 downward is repeated in reverse, that is, the power member 12 drives the knocking ball 16 to move upward and re-contact the magnetic ring 19. At the same time, the lower sealing ring 17 and the upper sealing ring 21 re-seal the waste storage chamber 221. At the same time, the sealing member 20 releases the sealing of the two semi-ring through holes on the partition member 18. The above steps are repeated to cool the elastic fiber.

[0038] After the raw materials in the barrel 2 are completely squeezed out, the worker stops the spinning machine 1, the brushless motor 7 and the cooling part 9, and then repeats the steps of Example 1 to remove the threaded ring 6 from the mounting part 5, and clean the condensate and impurities accumulated in the threaded ring 6, and then clean the sponge ring 23 with clean water, and finally reinstall the threaded ring 6 to the mounting part 5.

[0039] During the process of the melt spinning machine extruding the molten raw materials through the spinneret, a small portion of the raw materials will "splash" at the spinneret position and eventually stick to the surface of the part next to the spinneret. As the raw materials accumulate on the surface of the part, they drip due to their own gravity. In this way, the raw materials are easy to drip onto the surface of the solidified elastic fiber, causing the finished elastic fiber to be rough. The existing device needs to be stopped at intervals for cleaning during operation, resulting in low production efficiency.

[0040] Example 3: Based on Example 2, please refer to Fig.12 , and further includes a plurality of storage rings 30 that are evenly distributed. The storage rings 30 are used to collect the raw materials flowing on the adjacent protective tubes 11 . The storage rings 30 are fixedly connected to the lower side of the adjacent protective tubes 11 .

[0041] After the raw material is ejected from the spinneret 4, it diffuses around the holes of the spinneret 4, a part of the raw material contacts the inner side of the protective tube 11 and flows downward along it, and finally accumulates on the upper side of the protective tube 11 and the adjacent storage ring 30, thereby reducing the influence of the splashing raw material on the smoothness of the elastic fiber. After the spinning is completed, the worker removes the mounting part 5, and then cleans the raw material accumulated on the upper side of the storage ring 30 for next use.

[0042] Example 4: Based on Example 3, please refer to Figure 1-Figure 12 A method for using a nylon elastic composite fiber spinning device, based on the above-mentioned nylon elastic composite fiber spinning device, specifically comprises the following steps: S1: Add raw materials into the barrel 2, start the spinning machine 1, the brushless motor 7 and the cooling member 9, the raw materials in the barrel 2 are ejected through the spinneret 4 to form elastic fibers, and at the same time, a portion of the raw materials splash to the inside of the protective cylinder 11, and flow along the protective cylinder 11 to the upper side of the adjacent storage ring 30, and the external gas is sucked into the threaded ring 6 and the mounting member 5 by the fan 8. When the gas flows in the mounting member 5, the concave filter 15 intercepts the impurities contained in the gas; S2: The gas passes through the cooling member 9 and exchanges heat with it to form cold air. The cold air enters the corresponding shunt tube 10 through the gap between the mounting member 5 and the shunt tube 10, and flows downward along the gap between the shunt tube 10 and the adjacent protective tube 11 to exchange heat with the elastic fiber. S3: The gas drives the power member 12 to rotate while flowing along the mounting member 5. The power member 12 drives the scraper 14 to scrape off the condensed liquid condensed on the lower side of the cooling member 9 and guide it to the sponge ring 23. Then the power member 12 drives the inner gear ring 27 to rotate. The inner gear ring 27 controls the extrusion member 24 to squeeze the sponge ring 23 through the triangular block 28, so that the water in the sponge ring 23 is evenly distributed. S4: the inner gear ring 27 rotates and releases the extrusion member 24, so that the extrusion member 24 and the sponge ring 23 are reset. Then, the inner gear ring 27 moves downward under the action of the guide groove 291, so that the knocking ball 16 knocks the concave filter screen 15, and the impurities intercepted by the concave filter screen 15 are shaken off. Then, the gas entrains the impurities through the waste storage cavity 221 and the sponge ring 23, and the impurities are intercepted in the sponge ring 23; S5: The inner gear ring 27 moves upward and resets under the action of the guide groove 291, and the knocking ball 16 moves upward and resets. After the raw materials in the barrel 2 are completely squeezed out, the mounting part 5 is removed and the raw materials accumulated on the upper side of the storage ring 30 are cleaned, and then the sponge ring 23 is cleaned.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present application, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of this application.
