Description

Technical Field

[0001] This invention relates to the field of spinning equipment, and particularly to a three-component parallel composite fiber spinning device and method. Background Technology

[0002] Composite fiber spinning refers to a spinning method in which two or more polymer streams with different properties are fed separately into the same spinning assembly, converge at appropriate locations within the assembly, and extruded and solidified into fibers through a single spinneret. The polymers used in composite spinning generally possess different chemical or physical properties, but belong to the same chemical genus. This allows for a certain degree of adhesion (compatibility) at the interfaces of the different polymer components, preventing delamination between the components during the spinning and stretching process. The greater the difference in polymer properties, the better the fiber modification effect.

[0003] The three-component composite fibers, after being spun, will aggregate together to form spun fiber fabric. After the spun fiber fabric is made, it needs to be wound up. The general winding method is to drive the rotating shaft with a motor, that is, to rotate the roller to achieve the purpose of winding up the spinning. A winding cylinder is fitted on the rotating shaft. Existing three-component composite fiber spinning equipment cannot achieve the purpose of dust prevention when winding up the spinning. As a result, dust in the air will come into contact with the spinning during the processing, which will affect the quality of spinning.

[0004] Therefore, it is necessary to propose a three-component parallel composite fiber spinning device and method to solve the above problems. Summary of the Invention

[0015] The present invention also discloses a three-component parallel composite fiber spinning method, which further includes the following steps: First, three or more polymer materials with different properties are respectively fed into the same spinning assembly, converged at appropriate parts of the assembly, extruded and solidified into fibers from the same spinneret, and cooled to become fiber spun fabric; Second, the fiber spun fabric is clamped and supported by a clamping mechanism, and disinfection and winding are completed by a disinfection and winding mechanism.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. After being gripped by the clamping hand, the fiber spun fabric will pass through the gap between the lower pressure plate and the support block. When one end of the fiber spun fabric is continuously wound by the sterilization and winding mechanism, it will move the fiber spun fabric. The upper surface of the fiber spun fabric will contact the cleaning teeth at the bottom of the lower pressure plate to scrape off the excess fiber filaments remaining on the upper surface of the fiber spun fabric. At the same time, the distance between the lower pressure plate and the support block can be adjusted by the extension and retraction of the first cylinder and the first electric push rod to accommodate fiber spun fabrics of different thicknesses, which is convenient for actual processing needs.

[0018] 2. In the actual operation of this invention, the hot air blower discharges the generated high-temperature gas from the upper exhaust box, and the fiber spun fabric passes between the upper exhaust box and the lower air receiving box. The upper exhaust box and the lower air receiving box play a supporting and limiting role for the fiber spun fabric. At the same time, the high-temperature air is discharged from the air groove of the upper exhaust box to iron the upper surface of the fiber spun fabric, improve the flatness of the fiber spun fabric, and under the action of high temperature, the moving fiber spun fabric can be sterilized and disinfected to avoid the growth of bacteria in production and improve the hygiene and safety of winding.

[0019] 3. The generated high-temperature wind will pass through the gaps between the fibers in the spun fabric and enter the lower air receiving box, where it will be received. Because the distance between the upper air receiving box and the lower air receiving box is small, the wind is sprayed vertically, which can prevent excess wind from scattering to both sides.

[0020] 4. In addition, after the fiber spun fabric is sterilized by high temperature, the fiber spun fabric passes through the gap between the second adsorption box and the first adsorption box, and the upper and lower surfaces of the fiber spun fabric are pressed against the semi-circular ends of the second and first adsorption boxes. The two semi-circular ends can clamp and fix the fiber spun fabric. Since the fiber spun fabric has just been sterilized by high temperature, the fibers on the fiber spun fabric will shrink due to heat. Through the pressing and squeezing of the two semi-circular ends, the upper and lower surfaces of the fiber spun fabric can be more easily squeezed flat. At the same time, the air pump is started, so that the second adsorption box, the first adsorption box, and the lower air box all generate suction to adsorb the moving fiber spun fabric. On the one hand, it can adsorb excess heat to avoid heat accumulation, and on the other hand, it can adsorb dust on the upper and lower surfaces of the fiber spun fabric to improve the cleanliness of the fiber spun fabric. The suction generated by the lower air box can increase the exhaust speed of the high temperature air and prevent the high temperature air from scattering.

[0021] 5. In the actual operation of this invention, the start of the third motor can drive the winding drum to rotate, thereby winding the sterilized fiber spun fabric into a U-shaped sterilization box, which can prevent the entry of external dust. At the same time, the sterilizer can continuously sterilize the wound fiber spun fabric, improving the hygiene level. In addition, one end of the U-shaped sterilization box can be opened by rotating a door, which is convenient for personnel to move and process the wound fiber spun fabric.

[0022] 6. A gap is left between the two vertically corresponding pressure rollers. The fiber-spun fabric after the fiber filaments have been scraped off passes between the two pressure rollers. The two pressure rollers are driven by the corresponding second motors to rotate relative to each other, thereby crushing the passing fiber-spun fabric, making the fiber-spun fabric flatter and avoiding the formation of bulges that would affect the winding quality. At the same time, the two pressure rollers also play a supporting role for the moving fiber-spun fabric, preventing the fiber-spun fabric from sinking due to its own weight during the movement.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To address the issue of winding up the spun fiber fabric after production, the conventional method involves rotating a shaft (i.e., a roller) driven by a motor to achieve the winding process. A winding cylinder is typically fitted onto the shaft. However, existing three-component composite fiber spinning devices cannot effectively prevent dust from entering the spun fibers during winding. This allows airborne dust to come into contact with the fibers during processing, affecting the spinning quality. This invention provides a solution... Figure 1 - Figure 8 The three-component parallel composite fiber spinning device shown includes a worktable 1. A clamping mechanism 2 for supporting the fiber spinning fabric is fixed at the top of the worktable 1. A sterilization and winding mechanism 3 is provided on one side of the clamping mechanism 2. The sterilization and winding mechanism 3 is used to wind and sterilize the supported fiber spinning fabric. One end of the fiber spinning fabric is supported by the clamping mechanism 2, and the other end of the fiber spinning fabric is continuously wound by the sterilization and winding mechanism 3. During the winding process, the fiber spinning fabric is moved.

[0034] A slide rail 7 is provided on the other side of the clamping mechanism 2. A sliding seat 8 is slidably fitted on the slide rail 7. A first motor 9 is fixed on the sliding seat 8. A drive shaft is provided on the side of the first motor 9 near the clamping mechanism 2. A turntable 16 is fixed on the drive shaft. A drive cylinder 17 is fixed on the side of the turntable 16 near the clamping mechanism 2. A gripper 13 is connected to one side of the drive cylinder 17. The fiber spun fabric passes through the gripper 13. A second cylinder is connected to one end of the sliding seat 8. The second cylinder is fixed on the worktable 1. The second cylinder is used to push the sliding seat 8 to move back and forth.

[0035] In the actual use of the present invention, the fiber spinning cloth can be clamped and supported by the clamp 13. At the same time, the second cylinder can push the sliding seat 8 and the clamp 13 on the sliding seat 8 to move back and forth, so as to change the distance between the clamp 13 and the clamping mechanism 2, so as to facilitate tightening or loosening of the fiber spinning cloth and facilitate actual operation.

[0036] The clamping mechanism 2 includes a support frame 4. The top and bottom of the support frame 4 are respectively connected to a lower pressure plate 10 and a support block 5. A gap is left between the lower pressure plate 10 and the support block 5 for the fiber spinning cloth to pass through. The bottom of the lower pressure plate 10 is provided with cleaning teeth 11 along the length direction. The bottom of the support frame 4 is fixed with a support plate 19, which is fixed to the top of the workbench 1. The bottom of the workbench 1 is fixed with a first electric push rod 18. The top of the first electric push rod 18 extends out of the support plate 19 and the extended end is connected to the bottom of the support block 5. The top of the support frame 4 is fixed with a first cylinder 6. The bottom of the first cylinder 6 is provided with a telescopic end, and the bottom of the telescopic end is connected to the top of the pressure plate 10. A triangular block 12 is provided on one side of the lower pressure plate 10. The tip of the triangular block 12 faces down and the top of the triangular block 12 is connected to the telescopic end. The bottom of the lower pressure plate 10 and the triangular block 12 are flush.

[0037] In the actual operation of this invention, the fiber spun fabric held by the clamp 13 will pass through the gap between the lower pressure plate 10 and the support block 5. When one end of the fiber spun fabric is continuously wound by the sterilization and winding mechanism 3, it will drive the fiber spun fabric to move. The upper surface of the fiber spun fabric will contact the cleaning teeth 11 at the bottom of the lower pressure plate 10 to scrape off the excess fiber strands remaining on the upper surface of the fiber spun fabric. At the same time, the distance between the lower pressure plate 10 and the support block 5 can be adjusted by the extension and retraction of the first cylinder 6 and the first electric push rod 18 to adapt to fiber spun fabrics of different thicknesses, which is convenient for actual processing needs.

[0038] Two vertically corresponding pressure rollers 14 are provided on the side of the lower pressure plate 10 near the disinfection and winding mechanism 3. The two ends of the two pressure rollers 14 are rotatably connected to the two sides inside the support frame 4. Two second motors 15 are fixed on the outside of the support frame 4, and the two second motors 15 are respectively connected to the two pressure rollers 14 for driving.

[0039] A gap is left between the two vertically corresponding pressure rollers 14. The fiber spun fabric after the fiber filaments have been scraped off passes between the two pressure rollers 14. The two pressure rollers 14 are driven by the corresponding second motors 15 to rotate relative to each other, thereby crushing the passing fiber spun fabric, making the fiber spun fabric flatter and avoiding the formation of bulges that would affect the quality of winding. At the same time, the two pressure rollers 14 also play a supporting role for the moving fiber spun fabric, preventing the fiber spun fabric from sinking due to its own weight during the movement.

[0040] The disinfection and winding mechanism 3 includes a U-shaped disinfection box 22. The U-shaped opening of the U-shaped disinfection box 22 faces the lower pressure plate 10. An upper moving plate 28 and a lower moving plate 29 are raised and lowered on the side of the U-shaped disinfection box 22 near the lower pressure plate 10. An upper exhaust box 36 for discharging high-temperature steam and a lower steam receiving box 39 for receiving steam are respectively fixed on the side of the upper moving plate 28 and the lower moving plate 29 that are close to each other. A winding drum 32 is rotatably connected inside the U-shaped disinfection box 22. Fiber spun cloth passes through the gap between the upper exhaust box 36 and the lower steam receiving box 39 and is wound on the winding drum 32. A side plate 26 is fixed on one side of the U-shaped disinfection box 22, and a third motor 23 is fixed on one side of the side plate 26.

[0041] A hot air blower 35 is fixed at the top of the upper movable plate 28. A connecting pipe 37 is connected between the interior of the upper exhaust box 36 and the hot air blower 35. Air grooves 40 are opened on the opposite side of the upper exhaust box 36 and the lower air receiving box 39. The upper exhaust box 36 and the lower air receiving box 39 are vertically aligned.

[0042] In the actual operation of this invention, the hot air blower 35 discharges the generated high-temperature gas from the upper exhaust box 36, and the fiber spun fabric passes between the upper exhaust box 36 and the lower air receiving box 39. The upper exhaust box 36 and the lower air receiving box 39 provide support and limit for the fiber spun fabric. At the same time, the high-temperature air is discharged from the air groove 40 of the upper exhaust box 36 to iron the upper surface of the fiber spun fabric, improve the flatness of the fiber spun fabric, and sterilize the moving fiber spun fabric under the action of high temperature, so as to avoid the growth of bacteria in the production process and improve the hygiene and safety of the winding.

[0043] Furthermore, the generated high-temperature wind will pass through the gaps between the fibers in the spun fabric and enter the lower air receiving box 39, where it will be received. Since the distance between the upper air receiving box 36 and the lower air receiving box 39 is small, the wind is ejected vertically, which can prevent excess wind from scattering to both sides.

[0044] The upper exhaust box 36 and the lower air receiving box 39 are respectively fixed to the side away from the clamping mechanism 2, with the second adsorption box 20 and the first adsorption box 41 respectively. The opposite ends of the second adsorption box 20 and the first adsorption box 41 are each fixed with a semi-circular end 43. The semi-circular surfaces of the two semi-circular ends 43 are arranged opposite each other, and each of the opposite sides of the two semi-circular ends 43 is provided with an adsorption port 44. The two adsorption ports 44 are respectively connected to the interior of the corresponding second adsorption box 20 and the first adsorption box 41. The interiors of the second adsorption box 20 and the first adsorption box 41 are connected by an air pipe 42. The bottom end of the lower moving plate 29 is fixed with a vacuum pump 38. The air intake of the vacuum pump 38 is connected to the interior of the first adsorption box 41 and the lower air receiving box 39. The second adsorption box 20 and the first adsorption box 41 are respectively fixed to the ends of the upper moving plate 28 and the lower moving plate 29 that are close to each other.

[0045] In addition, after the fiber spun fabric is sterilized by high temperature, the fiber spun fabric passes through the gap between the second adsorption box 20 and the first adsorption box 41, and the upper and lower surfaces of the fiber spun fabric are pressed against the semi-circular ends 43 on the second adsorption box 20 and the first adsorption box 41. The two semi-circular ends 43 can clamp and fix the fiber spun fabric. Since the fiber spun fabric has just been sterilized by high temperature, the fibers on the fiber spun fabric will shrink when heated. Through the pressing and squeezing of the two semi-circular ends 43, it is easier to press and flatten the upper and lower surfaces of the fiber spun fabric. At the same time, the air pump 38 is started, so that the second adsorption box 20, the first adsorption box 41 and the lower air receiving box 39 all generate suction to adsorb the moving fiber spun fabric. On the one hand, it can adsorb excess heat to avoid heat accumulation, and on the other hand, it can adsorb dust on the upper and lower surfaces of the fiber spun fabric, improving the cleanliness of the fiber spun fabric.

[0046] The suction generated by the lower air box 39 can increase the exhaust speed of the high-temperature air and prevent the high-temperature air from scattering.

[0047] A sliding groove 27 is provided on the side of the side plate 26 near the clamping mechanism 2. Sliding blocks are fixed on one side of the upper moving plate 28 and the lower moving plate 29. The two sliding blocks are slidably engaged in the sliding groove 27. The upper moving plate 28 is located above the lower moving plate 29. One end of the winding drum 32 is driven and connected to the third motor 23. The end of the U-shaped disinfection box 22 away from the side plate 26 is rotatably connected to the pull door 33. An auxiliary handle 34 is fixed on one side of the pull door 33.

[0048] The top and bottom of the U-shaped disinfection box 22 are fixed with L-shaped brackets 30. The opposite sides of the two L-shaped brackets 30 are fixed with second electric push rods 31. The opposite ends of the two second electric push rods 31 are respectively fixedly connected to the upper moving plate 28 and the lower moving plate 29. Multiple sterilizers are provided on the inner wall of the U-shaped disinfection box 22. The sterilizers can use sterilization devices such as ultraviolet germicidal lamps. Since the winding time of the fiber spun fabric is relatively long, there is enough time to use ultraviolet germicidal lamps for sterilization. At the same time, the wound fiber spun fabric can also stay in the U-shaped disinfection box 22 to increase the sterilization time.

[0049] In the actual operation of this invention, the start of the third motor 23 can drive the winding drum 32 to rotate, thereby causing the winding drum 32 to wind and wrap the sterilized fiber spun fabric. The fiber spun fabric is wound into the U-shaped sterilization box 22, which can prevent the entry of external dust. At the same time, the sterilizer can continuously sterilize the wound fiber spun fabric, improving the hygiene level.

[0050] In addition, one end of the U-shaped disinfection box 22 can be opened by rotating the sliding door 33, which makes it convenient for personnel to move and process the rolled-up fiber spun fabric.

[0051] Support legs 21 are fixed at the four corners of the bottom of the workbench 1. Upright plates 25 are fixed on both sides of the bottom of the U-shaped disinfection box 22. A base plate 24 is fixed to the bottom of the two upright plates 25. The base plate 24 is fixed to the top of the workbench 1.

[0052] This invention also discloses a method for spinning three-component parallel composite fibers, comprising the following steps:

[0053] S1. Three or more polymers with different properties are fed into the same spinning assembly, merged at appropriate parts of the assembly, extruded and solidified into fibers from the same spinneret, and cooled to become fiber spun fabric.

[0054] S2. The spun fiber fabric is clamped and supported by the clamping mechanism 2, and disinfection and winding are completed by the disinfection and winding mechanism 3.

[0055] Three or more polymeric materials with different properties can include carbon nanotubes, polypropylene, and polylactic acid composite fiber materials. Specifically, carbon nanotube nanopowder is placed on a special transmission device of plasma processing equipment. Under atmospheric pressure and an open environment, plasma is directly sprayed onto the surface of carbon nanotube nanopowder, causing the carbon nanotube nanopowder to move in the plasma atmosphere. Other materials are also made into slices in this way to obtain composite slices, which are then melted to obtain fiber spun fabric.

[0056] Working principle: The top of the workbench 1 is fixed with a clamping mechanism 2 that supports the fiber spinning cloth. A disinfection and winding mechanism 3 is provided on one side of the clamping mechanism 2. The disinfection and winding mechanism 3 is used to wind up and disinfect the supported fiber spinning cloth. One end of the fiber spinning cloth is supported by the clamping mechanism 2, and the other end of the fiber spinning cloth is continuously wound up by the disinfection and winding mechanism 3. During the winding process, the fiber spinning cloth is moved.

[0057] In the actual use of the present invention, the fiber spinning cloth can be clamped and supported by the clamp 13. At the same time, the second cylinder can push the sliding seat 8 and the clamp 13 on the sliding seat 8 to move back and forth, so as to change the distance between the clamp 13 and the clamping mechanism 2, so as to facilitate tightening or loosening of the fiber spinning cloth and facilitate actual operation.

[0058] The clamping mechanism 2 includes a support frame 4. The top and bottom ends of the support frame 4 are respectively connected to a lower pressure plate 10 and a support block 5. A gap is left between the lower pressure plate 10 and the support block 5 for the fiber spinning cloth to pass through. The fiber spinning cloth clamped by the clamp 13 will pass through the gap between the lower pressure plate 10 and the support block 5. When one end of the fiber spinning cloth is continuously wound by the sterilization and winding mechanism 3, it will drive the fiber spinning cloth to move. The upper surface of the fiber spinning cloth will contact the cleaning teeth 11 at the bottom of the lower pressure plate 10 to scrape off the excess fiber strands remaining on the upper surface of the fiber spinning cloth. At the same time, the distance between the lower pressure plate 10 and the support block 5 can be adjusted by the extension and retraction of the first cylinder 6 and the first electric push rod 18 to adapt to fiber spinning cloth of different thicknesses and facilitate actual processing needs.

[0059] A gap is left between the two vertically corresponding pressure rollers 14. The fiber spun fabric after the fiber filaments have been scraped off passes between the two pressure rollers 14. The two pressure rollers 14 are driven by the corresponding second motors 15 to rotate relative to each other, thereby crushing the passing fiber spun fabric, making the fiber spun fabric flatter and avoiding the formation of bulges that would affect the quality of winding. At the same time, the two pressure rollers 14 also play a supporting role for the moving fiber spun fabric, preventing the fiber spun fabric from sinking due to its own weight during the movement.

[0060] In the actual operation of this invention, the hot air blower 35 discharges the generated high-temperature gas from the upper exhaust box 36, and the fiber spun fabric passes between the upper exhaust box 36 and the lower air receiving box 39. The upper exhaust box 36 and the lower air receiving box 39 provide support and limit for the fiber spun fabric. At the same time, the high-temperature air is discharged from the air groove 40 of the upper exhaust box 36 to iron the upper surface of the fiber spun fabric, improve the flatness of the fiber spun fabric, and sterilize the moving fiber spun fabric under the action of high temperature, so as to avoid the growth of bacteria in the production process and improve the hygiene and safety of the winding.

[0061] Furthermore, the generated high-temperature wind will pass through the gaps between the fibers in the spun fabric and enter the lower air receiving box 39, where it will be received. Since the distance between the upper air receiving box 36 and the lower air receiving box 39 is small, the wind is ejected vertically, which can prevent excess wind from scattering to both sides.

[0062] In addition, after the fiber spun fabric is sterilized by high temperature, the fiber spun fabric passes through the gap between the second adsorption box 20 and the first adsorption box 41, and the upper and lower surfaces of the fiber spun fabric are pressed against the semi-circular ends 43 on the second adsorption box 20 and the first adsorption box 41. The two semi-circular ends 43 can clamp and fix the fiber spun fabric. Since the fiber spun fabric has just been sterilized by high temperature, the fibers on the fiber spun fabric will shrink when heated. Through the pressing and squeezing of the two semi-circular ends 43, the upper and lower surfaces of the fiber spun fabric can be more easily pressed flat. At the same time, the air pump 38 is started, so that the second adsorption box 20, the first adsorption box 41 and the lower air box 39 all generate suction to adsorb the moving fiber spun fabric. On the one hand, it can adsorb excess heat to avoid heat accumulation, and on the other hand, it can adsorb dust on the upper and lower surfaces of the fiber spun fabric to improve the cleanliness of the fiber spun fabric. The suction generated by the lower air box 39 can increase the exhaust speed of the high temperature air and prevent the high temperature air from scattering.

[0063] In the actual operation of this invention, the start of the third motor 23 can drive the winding drum 32 to rotate, thereby causing the winding drum 32 to wind and wrap the sterilized fiber spun fabric. The fiber spun fabric is wound into the U-shaped sterilization box 22, which can prevent the entry of external dust. At the same time, the sterilizer can continuously sterilize the wound fiber spun fabric, improving the hygiene level. In addition, one end of the U-shaped sterilization box 22 can be opened by rotating the door 33, which makes it convenient for personnel to move and process the wound fiber spun fabric.
