Description

Technical Field

[0001] The present invention relates to the technical field of bio-based fiber production, in particular to a spinning device and a spinning method for bio-based fiber production. Background Art

[0002] Bio-based fiber refers to fiber made from renewable organisms or biological extracts, as distinguished from fiber produced from non-renewable petrochemical resources such as coal and oil. With the world's emphasis on green environmental protection and sustainable development, bio-based fiber production technologies continue to emerge and are widely used in many fields. The raw materials of bio-based fibers come from renewable biomass, with the characteristics of lower carbon footprint and overall carbon emission reduction or no carbon emission increase. After being discarded, whether it is biodegraded in the environment or burned to release carbon dioxide, no additional carbon emissions will be generated.

[0003] At present, when spinning devices are used for the production of bio-based fibers, most of the existing spinning devices do not have screening functions. The raw materials of bio-based fibers, such as plant fibers, microbial fermentation products, etc., often have differences in particle size, shape, chemical composition, etc. Impurities in the raw materials and particles that are too large or too small will affect the stability of the spinning process. For example, large particles may block the spinneret holes and cause spinning ends to break; small particles or powders may form flying flowers during the spinning process, increasing the difficulty of post-processing and even affecting the normal operation of the equipment. In addition, when spinning devices are used for the production of bio-based fibers, the fibers that have just been ejected are in a semi-fluid state. If they are directly water-cooled and fixed, it is easy to cause the bio-based fibers to have too much water content. Due to the water content of the fibers, If the diameter of the fiber is too large, the treatment agent will not be evenly distributed on the fiber surface during spraying, resulting in uneven spraying effect, which will affect the further treatment effect of the fiber, such as dyeing, coating, etc. The uneven spraying effect may cause differences in color, gloss, softness, etc. of the finished fiber, affecting product quality. After spraying the bio-based fiber, the bio-based fiber needs to be dried. The current spinning device cannot disperse the bio-based fiber. Some bio-based fibers will pile up together, which reduces the fiber drying efficiency. It takes a longer drying time to achieve the required degree of dryness. The fiber that is not fully dried may contain higher moisture, which affects the physical properties and chemical stability of the fiber, and will also affect the smooth progress of subsequent processing steps.

[0014] A spinning method for producing bio-based fibers, comprising the following steps:

[0015] A: The staff first pours the bio-based fiber raw material on the top of the filter. At this time, the staff turns on the first motor, heating pump and fan on one side. The fan will draw the hot air generated by the heating pump into the inside of the extrusion box, causing the temperature around the auger to rise. Then the hot air will flow into the heating pump again, causing the hot air to circulate continuously. The rotating second pulley drives the auger to rotate, and the first cam on one side will also rotate continuously, causing the mounting shell to shake back and forth. The filter screens the bio-based fiber raw material, and the screened bio-based fiber raw material falls into the inside of the extrusion box and is transported through the auger. In the process of transporting the bio-based fiber raw material, the bio-based fiber raw material is melted by heat and flows to the lower part of the extrusion box. The first threaded rod under the extrusion box rotates continuously, and the extrusion rod is pushed back and forth while rotating, and the melted bio-based fiber raw material is continuously pushed into the liquid pipe through the extrusion rod. At the same time, the staff turns on the second motor, so that the second threaded rod rotates, and the moving platform on the surface of the second threaded rod descends. The extrusion head approaches the water cooling box below, and the fans on both sides of the extrusion head are also turned on. The bio-based fiber raw material enters the extrusion head and is extruded through the bottom of the extrusion head. The extruded bio-based fiber is immediately cooled and shaped by the fans on both sides, and then the bio-based fiber falls into the water cooling box below. The cold water inside the water cooling box cools and shapes the bio-based fiber again, completing the extrusion molding operation of the bio-based fiber.

[0016] B: After the bio-based fiber is cooled and shaped inside the water-cooled box, the staff will fish out the bio-based fiber inside the water-cooled box and wind it on the surface of the winding roller on the right, and wind one end of the bio-based fiber on the surface of the winding roller on the left. At this time, the staff will turn on the third motor at the rear, and the rotating rod above will rotate, so that the second cam will push the extrusion plate down, and the extrusion plate will reciprocate to squeeze the bio-based fiber above the fixed plate, thereby squeezing out excess water on the surface of the bio-based fiber after water cooling and shaping. The winding rollers on both sides rotate, so that the bio-based fiber wound on the surface of the right winding roller gradually winds around the surface of the left winding roller. When the bio-based fiber keeps moving, the installation rod below also rotates, and the fan blades are used to continuously blow air to the bio-based fiber above the fixed plate, further improving the treatment effect of excess water on the surface of the bio-based fiber;

[0017] C: After the bio-based fiber has been extruded, the staff removes the bio-based fiber wound on the surface of the left winding roller and places it on the right side of the top of the conveyor belt. At this time, the staff turns on the water pump so that the water pump draws the bio-based fiber treatment agent in the water tank into the water pipe, and the nozzle sprays the bio-based fiber treatment agent. At the same time, the staff turns on the drive motor, and the output shaft of the drive motor drives the third threaded rod to rotate, so that the moving blocks on the front and rear sides move in opposite directions. The rack plate drives the gear below to rotate, and controls the rotation direction of the output shaft of the drive motor, so that the adjustment rod rotates back and forth continuously, and the nozzle swings back and forth to sprinkle the bio-based fiber treatment agent, so that the bio-based fiber treatment agent is evenly sprayed on the surface of the bio-based fiber on the surface of the conveyor belt, completing the spraying operation on the bio-based fiber;

[0018] D: The conveyor belt moves the sprayed bio-based fibers to the left. At this time, the staff turns on the fifth motor, and the rotating roller on the right rotates. When the bio-based fibers on the surface of the conveyor belt move to the right side of the rotating roller, the rotating vibration plate will pick up the bio-based fibers and vibrate them, thereby dispersing the accumulated bio-based fibers through vibration. The rotating vibration plate moves the bio-based fibers to the left side of the rotating roller and falls on the surface of the conveyor belt again. The staff turns on the heating fan, and the hot air enters the exhaust drying hood through the retractable hose. The moving plate on the surface of the fourth threaded rod drives the exhaust drying hood to move back and forth. When the bio-based fibers pass under the exhaust drying hood, the exhaust drying hood evenly blows the hot air on the dispersed bio-based fiber surface, thereby drying the bio-based fibers, thereby completing the spinning operation of the bio-based fibers.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention has a screening function. During the feeding process, the bio-based fiber raw material is screened. The screening process can remove large particles of impurities, foreign matter, etc. in the raw material, ensure the purity of the raw material entering the extrusion equipment, and reduce equipment wear and failure caused by impurities. Through screening, the particle size of the raw material can be made more uniform, which helps to obtain more stable fiber quality during the extrusion process. The device can first air-cool the bio-based fiber when the bio-based fiber is extruded, and then water-cool it to avoid excessive water content in the bio-based fiber. The device also has an extrusion function. By extruding to remove excess water, the tightness of the fiber structure can be maintained, thereby improving the strength of the fiber. After removing the excess water, the stability of the fiber is enhanced. The removal of excess water makes the fiber surface drier. When spraying, the water and the spray liquid can be more evenly attached to the fiber, avoiding the uneven spraying caused by excessive water. The device also has a dispersion function, avoiding the accumulation of the bio-based fiber after spraying, maintaining the loose state of the fiber, and can evenly dry the fiber, thereby improving the overall quality of the fiber.

[0050] A spinning method for producing bio-based fibers, comprising the following steps:

[0051] A: The staff first pours the bio-based fiber raw material onto the top of the filter 107. At this time, the staff turns on the first motor 52, the heating pump 7 and the fan 8 on one side. The fan 8 draws the hot air generated by the heating pump 7 into the interior of the extrusion box 2, so that the temperature around the auger 4 rises. Then the hot air will flow into the heating pump 7 again, so that the hot air circulates continuously. The rotating second pulley 54 drives the auger 4 to rotate, and the first cam 104 on one side also rotates continuously, so that the mounting shell 106 shakes back and forth. The filter 107 screens the bio-based fiber raw material, and the screened bio-based fiber raw material falls into the interior of the extrusion box 2 and is transported by the auger 4. In the process of transporting the bio-based fiber raw material, the bio-based fiber raw material is melted by heat and flows to the bottom of the extrusion box 2. The first threaded rod 62 rotates continuously, and the extrusion rod 61 is pushed back and forth while rotating, and the melted bio-based fiber raw material is continuously pushed into the liquid passage 14 through the extrusion rod 61. At the same time, the staff turns on the second motor 122, so that the second threaded rod 123 rotates, and the moving platform 124 on the surface of the second threaded rod 123 descends, and the extrusion head 125 approaches the water cooling box 13 below. The fans 127 on both sides of the extrusion head 125 are also turned on, and the bio-based fiber raw material enters the extrusion head 125 and is extruded through the bottom of the extrusion head 125. The extruded bio-based fiber is immediately air-cooled and shaped by the fans 127 on both sides, and then the bio-based fiber falls into the water cooling box 13 below. The cold water in the water cooling box 13 cools and shapes the bio-based fiber again, completing the extrusion molding operation of the bio-based fiber;

[0052] B: After the bio-based fiber is cooled and shaped inside the water-cooled box 13, the staff will fish out the bio-based fiber inside the water-cooled box 13 and wind it on the surface of the winding roller 17 on the right, and wind one end of the bio-based fiber on the surface of the winding roller 17 on the left. At this time, the staff will turn on the third motor 186 at the rear, and the rotating rod 182 on the top will rotate, so that the second cam 184 will push the extrusion plate 181 to descend, and the extrusion plate 181 will reciprocate to squeeze the bio-based fiber above the fixed plate 19, thereby squeezing out excess water on the surface of the bio-based fiber after water cooling and shaping. The winding rollers 17 on both sides rotate, so that the bio-based fiber wound on the surface of the right winding roller 17 gradually winds around the surface of the left winding roller 17. When the bio-based fiber keeps moving, the mounting rod 188 below also rotates, and the fan blades 183 are used to continuously blow air to the bio-based fiber above the fixed plate 19, further improving the treatment effect of excess water on the surface of the bio-based fiber;

[0053] C: After the bio-based fiber is extruded, the staff removes the bio-based fiber wound on the surface of the left winding roller 17 and places it on the right side of the top of the conveyor belt 20. At this time, the staff turns on the water pump 23, so that the water pump 23 draws the bio-based fiber treatment agent in the water tank 22 into the water pipe 24, and the nozzle 27 sprays the bio-based fiber treatment agent. At the same time, the staff turns on the drive motor 262, and the output shaft of the drive motor 262 drives the third threaded rod 263 to rotate, so that the moving blocks 264 on the front and rear sides move in opposite directions, and the rack plate 265 drives the gear 267 below to rotate, and controls the rotation direction of the output shaft of the drive motor 262, so that the adjustment rod 266 rotates back and forth continuously, so that the nozzle 27 swings back and forth to sprinkle the bio-based fiber treatment agent, so that the bio-based fiber treatment agent is evenly sprayed on the surface of the bio-based fiber on the surface of the conveyor belt 20, completing the spraying operation on the bio-based fiber;

[0054] D: The conveyor belt 20 moves the sprayed bio-based fibers to the left. At this time, the staff turns on the fifth motor 311, and the rotating roller 291 on the right rotates. When the bio-based fibers on the surface of the conveyor belt 20 move to the right side of the rotating roller 291, the rotating vibration plate 295 will pick up the bio-based fibers and vibrate them, thereby dispersing the accumulated bio-based fibers through vibration. The rotating vibration plate 295 moves the bio-based fibers to the left side of the rotating roller 291 and falls on the surface of the conveyor belt 20 again. The staff turns on the heating fan, and the hot air enters the exhaust drying hood 32 through the retractable hose. The moving plate 315 on the surface of the fourth threaded rod 314 drives the exhaust drying hood 32 to move back and forth. When the bio-based fibers pass under the exhaust drying hood 32, the exhaust drying hood 32 evenly blows the hot air on the dispersed bio-based fiber surface, thereby drying the bio-based fibers, thereby completing the spinning operation of the bio-based fibers.

10. A spinning method for producing bio-based fibers, applied to the spinning device for producing bio-based fibers as claimed in claim 9, It is characterized in that The following steps are involved: A: The staff first pours the bio-based fiber raw material onto the top of the filter (107). At this time, the staff turns on the first motor (52), the heating pump (7) and the fan (8) on one side. The fan (8) draws the hot air generated by the heating pump (7) into the interior of the extrusion box (2), so that the temperature around the auger (4) rises. The hot air then flows into the interior of the heating pump (7) again, so that the hot air circulates continuously. The rotating second pulley (54) drives the auger (4) to rotate. The first cam (104) on one side also rotates continuously, thereby causing the mounting shell (106) to shake back and forth. The filter (107) screens the bio-based fiber raw material. The screened bio-based fiber raw material falls into the interior of the extrusion box (2) and is transported through the auger (4). In the process of transporting the bio-based fiber raw material, the bio-based fiber raw material is melted by the heat and flows to the bottom of the interior of the extrusion box (2). The bottom of the extrusion box (2) The first threaded rod (62) is continuously rotated, and the extrusion rod (61) is pushed back and forth while rotating, and the melted bio-based fiber raw material is continuously pushed into the liquid passage (14) through the extrusion rod (61). At the same time, the staff turns on the second motor (122), thereby causing the second threaded rod (123) to rotate, and the moving platform (124) on the surface of the second threaded rod (123) descends, and the extrusion head (125) approaches the water cooling box (13) below. The fans (127) on both sides of the extrusion head (125) are also turned on, and the bio-based fiber raw material enters the extrusion head (125) and is extruded through the bottom of the extrusion head (125). The extruded bio-based fiber is immediately air-cooled and shaped by the fans (127) on both sides, and then the bio-based fiber falls into the water cooling box (13) below. The cold water in the water cooling box (13) cools and shapes the bio-based fiber again, completing the extrusion molding operation of the bio-based fiber; B: After the bio-based fiber is cooled and shaped inside the water-cooling box (13), the staff takes out the bio-based fiber inside the water-cooling box (13) and winds it around the surface of the winding roller (17) on the right, and winds one end of the bio-based fiber around the surface of the winding roller (17) on the left. At this time, the staff turns on the third motor (186) at the rear, and the rotating rod (182) at the top rotates, thereby causing the second cam (184) to push the extrusion plate (181) down, and the extrusion plate (181) reciprocates back and forth against the fixed plate (19). The bio-based fibers above are squeezed, thereby squeezing out excess water on the surface of the bio-based fibers after water cooling and setting, and the winding rollers (17) on both sides are rotated, so that the bio-based fibers wound on the surface of the right winding roller (17) are gradually wound on the surface of the left winding roller (17), and when the bio-based fibers are continuously moved, the mounting rod (188) below is also rotated, and the fan blades (183) are continuously used to blow air to the bio-based fibers above the fixed plate (19), thereby further improving the treatment effect of excess water on the surface of the bio-based fibers; C: After the bio-based fiber has been squeezed, the staff removes the bio-based fiber wound on the surface of the left winding roller (17) and places it on the right side of the top of the conveyor belt (20). At this time, the staff turns on the water pump (23) so that the water pump (23) draws the bio-based fiber treatment agent in the water tank (22) into the water pipe (24), and the nozzle (27) sprays the bio-based fiber treatment agent. At the same time, the staff turns on the drive motor (262), and the output shaft of the drive motor (262) drives the third screw The pattern rod (263) rotates, thereby causing the moving blocks (264) on the front and rear sides to move in opposite directions, and the rack plate (265) drives the gear (267) below to rotate, thereby controlling the rotation direction of the output shaft of the drive motor (262), so that the adjustment rod (266) continuously rotates back and forth, causing the spray head (27) to swing back and forth to spray the bio-based fiber treatment agent, so that the bio-based fiber treatment agent is evenly sprayed on the surface of the bio-based fibers on the surface of the conveyor belt (20), thereby completing the spraying operation on the bio-based fibers; D: The conveyor belt (20) moves the sprayed bio-based fibers to the left. At this time, the staff turns on the fifth motor (311), and the rotating roller (291) on the right rotates. When the bio-based fibers on the surface of the conveyor belt (20) move to the right side of the rotating roller (291), the rotating vibration plate (295) picks up the bio-based fibers and vibrates them, thereby dispersing the accumulated bio-based fibers through vibration. The rotating vibration plate (295) moves the bio-based fibers to the left side of the rotating roller (291) and drops them on the surface of the conveyor belt (20) again. The staff turns on the heating fan, and the hot air enters the exhaust drying hood (32) through the retractable hose. The moving plate (315) on the surface of the fourth threaded rod (314) drives the exhaust drying hood (32) to move back and forth. When the bio-based fibers pass under the exhaust drying hood (32), the exhaust drying hood (32) evenly blows the hot air on the surface of the dispersed bio-based fibers, thereby drying the bio-based fibers, thereby completing the spinning operation of the bio-based fibers.
