[0017] Step 4: Finally, the yarn is wound on the winding drum.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The present application uses a cutter to cut the decorative yarn into short-fiber fluff, and uses a twisting drum to twist the two core yarns and the fluff, so that the fluff on the surface of the spun yarn is fluffy and not easy to fall off, and there is no need to perform traditional polishing, raising and napping processes on the fabric or yarn, thereby reducing damage to the yarn fibers and ensuring the quality of the product; and the core yarns of the fluff yarn are all composed of fine yarn, and the change of product performance is relatively convenient.

The sealing cover and the protective tube can block the cut decorative yarn to prevent the cut decorative yarn from floating into the air.

[0021] 3. In the process of preparing the fluff yarn of the present application, the decorative yarn on the surface of the decorative yarn roller passes between two driving rollers and bypasses multiple combing rollers one by one. The driving motor drives multiple rotating shafts and combing rollers to rotate. The combing roller rotates to comb the decorative yarn through the combing teeth, which can make the decorative yarn loose, convenient for subsequent cutting to form short fiber fluff, and in the process of combing the decorative yarn, the debris in it can be removed to ensure the quality of the subsequent yarn.

DETAILED DESCRIPTION

[0024] See also Figures 1-13 The present application provides a technical solution: a fluffing machine for preparing fluffy and colorful functional fluff yarn, comprising a mounting plate 1 and a decorative yarn roller 2, a driving roller 3 sequentially distributed on the mounting plate along a decorative yarn conveying path, a raising mechanism, a twisting mechanism and a winding drum 5, and a plurality of core rollers 4 for assisting twisting;

[0025] The pile raising mechanism includes a protective tube 1405 mounted on the surface of the mounting plate 1. The upper end of the protective tube 1405 is fixedly connected to a telescopic member 1403, and a cutter 1404 is provided at the end of the telescopic member 1403. When the telescopic member 1403 drives the cutter 1404 to reciprocate, the decorative yarn can be cut off, so that the decorative yarn falls into the protective tube 1405 in a broken pile state.

[0026] The twisting mechanism includes a twisting drum 17 arranged on the mounting plate 1 below the protective drum 1405. The broken wool inside the protective drum 1405 can fall into the twisting drum 17, and the core wire on the surface of the core wire roller 4 enters the twisting drum 17 from between the protective drum 1405 and the twisting drum 17. When the twisting drum 17 rotates, the core wire can wrap the broken wool and twist it into yarn, and finally the yarn is wound up by the winding drum 5.

[0027] During the preparation of the fluffy yarn, the decorative yarn on the surface of the decorative yarn roller 2 passes through between the two driving rollers 3 and extends to the inside of the protective tube 1405. The telescopic part 1403 drives the cutter 1404 to move back and forth to cut the decorative yarn moved to the inside of the protective tube 1405 into short fiber fluff. The cut-off fluff then falls down along the protective tube 1405 to the inside of the twisting tube 17. At the same time, the core wires wrapped on the surface of the two core wire rollers 4 enter the inside of the twisting tube 17 from between the protective tube 1405 and the twisting tube 17. The two core wires are fine yarns. Then the core wires and the broken fluff are gathered under the action of the twisting tube 17 to form a relatively loose yarn, in which the broken part is exposed on the outside of the yarn to cooperate with the yarn to form fluffy yarn.

[0028] The present invention uses a cutter 1404 to cut the decorative yarn into short fiber pile, and uses a twisting drum 17 to twist the two core yarns and the pile, so that the pile on the surface of the spun yarn is fluffy and not easy to fall off, and does not require traditional grinding, raising and napping processes on the fabric or yarn, thereby reducing damage to the yarn fibers and ensuring product quality.

[0029] Moreover, the core yarns of the fluffy yarns are all composed of fine yarns, and the change of product performance is relatively convenient. In this application, since the raising method of cutting and then covering is adopted, it can be ensured that when the two core yarns and decorative yarns can use different colors and different functional yarns, compared with the polished raising method, the product color and texture are clearer and more controllable; therefore, the raising method of this application increases the diversity of the appearance and color of the yarn, making the finished yarn uniquely fluffy, colorful and functional.

[0030] During the preparation of the fluff yarn, the decorative yarn cannot move stably into the inside of the protective tube 1405. As a further solution of the present application, a blowing frame 14 located above the protective tube 1405 is fixedly installed on the surface of the mounting plate 1. The decorative yarn passes through the blowing frame 14 and enters the protective tube 1405. The cutter 1404 is fitted with the bottom of the blowing frame 14. An air storage box 12 is fixedly installed on the surface of the mounting plate 1. A connecting pipe 13 is connected between the air storage box 12 and the blowing frame 14. An air inlet 1401 is provided on the surface of the blowing frame 14 at a connection position corresponding to the connecting pipe 13. A guide plate 1402 is fixedly connected to the inner wall of the blowing frame 14 near the air inlet 1401, and a sealing cover 1701 is fixedly connected to the bottom of the protective tube 1405.

[0031] During the preparation of the fluff yarn, the decorative yarn moves to the inside of the blowing frame 14, and the compressed gas in the air storage box 12 is blown out from the blowing frame 14 through the connecting pipe 13 and the air inlet 1401. The airflow in the blowing frame 14 flows to the bottom of the blowing frame 14 under the action of the guide plate 1402. The decorative yarn in the blowing frame 14 passes through the blowing frame 14 under the action of the airflow and moves to the protective tube 1405. The airflow is conducive to guiding the decorative yarn, so that the conveyed decorative yarn can reliably enter the protective tube 1405, and then the cutter 1404 cuts the decorative yarn into short fiber fluff. The cut decorative yarn moves downward along the protective tube 1405 to the inside of the twisting tube 17 under the action of the airflow. The sealing cover 1701 and the protective tube 1405 can block the cut decorative yarn to prevent the cut decorative yarn from floating into the air.

[0032] During the preparation of fluff yarn, the surface of the decorative yarn is easily contaminated with debris during storage and transportation, and the decorative yarn is arranged in disorder, and the broken piles are entangled when cut. As a further solution of the present application, a plurality of rotating shafts 7 are rotatably connected to the surface of the mounting plate 1, and combing rollers 8 are fixedly installed on the surfaces of the multiple rotating shafts 7. A plurality of combing teeth 9 are fixedly connected to the surface of the combing roller 8. The decorative yarn wrapped on the surface of the decorative yarn roller 2 passes through two driving rollers 3 and then bypasses the surfaces of the multiple combing rollers 8 one by one. A fixed plate 10 is fixedly connected to the surface of the mounting plate 1 facing away from the combing roller 8, and a drive motor 11 is fixedly installed on the surface of the fixed plate 10. The rotating shaft 7 passes through the mounting plate 1, and the drive motor 11 is used to drive one of the rotating shafts 7 to rotate, and the other rotating shafts 7 are synchronously rotated through synchronous belts and gears.

[0033] During the preparation of the fluff yarn, the decorative yarn on the surface of the decorative yarn roller 2 passes between the two driving rollers 3 and bypasses multiple combing rollers 8 one by one. The driving motor 11 drives the multiple rotating shafts 7 and the combing rollers 8 to rotate. The combing rollers 8 rotate to comb the decorative yarn through the combing teeth 9, which can make the decorative yarn loose and facilitate subsequent cutting to form short fiber fluff. In addition, in the process of combing the decorative yarn, the debris in it can be removed to ensure the quality of the subsequent yarn.

[0034] During the preparation of the fluff yarn, after the two core wires are twisted with the broken fluff, the fluff still falls off. As a further solution of the present application, an installation opening 18 is provided on the surface of the mounting plate 1 corresponding to the lower side of the twisting drum 17. A fixed yarn tube 19 is fixedly installed in the installation opening 18. The surface of the fixed yarn tube 19 is wound with a fixed yarn 6. The upper end of the fixed yarn tube 19 is rotatably connected to a rotating ring 20. The surface of the fixed yarn tube 19 is fixedly connected to a small motor 21 for driving the rotating ring 20 to rotate. An L-shaped winding rod 22 is fixedly connected to the surface of the rotating ring 20. A winding hole 23 is provided on the surface of the winding rod 22. The fixed yarn 6 passes through the winding hole 23 and is wound around the twisted core wire and the fluff surface. A mounting block 15 is fixedly installed on the surface of the mounting plate 1. A driving ring 16 that passes through the mounting block 15 is fixedly connected to the surface of the mounting block 15. The twisting drum 17 is located on the inner side of the driving ring 16 and is fixedly connected to the driving ring 16.

[0035] During the preparation of the fluff yarn, the driving ring 16 on the surface of the mounting block 15 drives the twisting drum 17 to rotate to twist the two core wires and the broken fluff once. After passing through the twisting drum 17, the yarn after one twist moves to the position of the fixed yarn tube 19 and passes through the middle of the fixed yarn tube 19. The small motor 21 drives the rotating ring 20 to rotate synchronously with the winding rod 22. The winding rod 22 rotates and winds the fixed yarn 6 around the surface of the yarn. The present application uses the fixed yarn 6 to wrap and cover the two core wires and the fluff. The fixed yarn 6 wraps the core wire and the fluff to further fix the state of the core wire and the fluff, thereby making the connection between the core wire and the fluff tighter and ensuring the stability of the yarn.

[0036] During the preparation of the fluff yarn, the wound solid yarn 6 cannot be tightly combined with the core wire. As a further solution of this application, the bottom of the solid yarn tube 19 is rotatably connected to a hollow spindle 24, and the bottom of the hollow spindle 24 is rotatably connected to a twister 25, which is located above the winding drum 5.

[0037] During the preparation of the fluffy yarn, the yarn wrapped by the solid yarn 6 moves to the position of the hollow spindle 24 and the twister 25. The hollow spindle 24 and the twister 25 cooperate to twist the reinforced fiber bundle to form a tight yarn. The twisting direction of the two core wires in the twisting drum 17 is opposite to the twisting direction of the hollow spindle 24, and the twisting amount is equal. The two core wires above the hollow spindle 24 have no twist. The finally prepared fluffy yarn is wound up by the winding drum 5. This application uses the hollow spindle 24 to combine the traditional four processes, namely spinning, primary twisting, secondary twisting, and winding into one process for yarn processing, with high production efficiency, rich product variety, and good economic benefits.

[0038] In the process of preparing the fluff yarn, the rotation speed adjustment of the combing roller 8 is relatively cumbersome. As a further solution of the present application, a conical wheel 26 is fixedly connected to the surface of the rotating shaft 7 close to the driving motor 11, and a driving shaft 27 is fixedly connected to the end of the output shaft of the driving motor 11. The driving shaft 27 is parallel to the busbar of the conical wheel 26. The surface of the driving shaft 27 is slidably connected to a transmission wheel 28 that fits the conical wheel 26. The surface of the transmission wheel 28 is slidably connected to an adjusting rod 29. The adjusting rod 29 passes through the fixed plate 10, and a through groove 30 is opened on the surface of the fixed plate 10 corresponding to the position of the adjusting rod 29. A threaded rod 31 that passes through the fixed plate 10 is rotatably connected in the through groove 30, and the threaded rod 31 is threadedly connected to the adjusting rod 29.

[0039] During the preparation of the fluff yarn, the driving motor 11 drives the driving shaft 27 and the transmission wheel 28 to rotate synchronously, the transmission wheel 28 drives the conical wheel 26 and the rotating shaft 7 to rotate synchronously, and the rotating shaft 7 drives the combing roller 8 and the combing teeth 9 to rotate synchronously to comb the decorative yarn. When the rotation speed of the combing roller 8 needs to be adjusted, the threaded rod 31 is rotated, and the adjustment plate 38 moves under the action of the threaded rod 31. The adjustment plate 38 drives the transmission wheel 28 to move along the surface of the driving shaft 27. The contact position of the transmission wheel 28 and the conical wheel 26 changes with the movement. The transmission ratio of the transmission wheel 28 and the conical wheel 26 gradually increases as the transmission wheel 28 moves from the end with a smaller radius of the conical wheel 26 to the end with a larger radius, which is conducive to simplifying the operation of adjusting the speed of the combing roller 8, reducing the time of additional operations, and improving production efficiency.

[0040] When the speed of the combing roller 8 changes, the movement of the decorative yarn changes with the combing speed of the combing roller 8, the amount of fluff blown out of the blowing frame 14 changes, and the tightness of the fixed yarn 6 when winding the fiber bundle cannot change together. As a further solution of the present application, the winding rod 22 is laterally retractable, and the bottom of the winding rod 22 is fixedly connected to a tilted pushing plate 32, and the surface of the fixed yarn tube 19 is fixedly connected to a plurality of telescopic blocks 33, and the bottoms of the plurality of telescopic blocks 33 are commonly fixedly connected to an adjusting ring 34 with an inclined side surface, and the side of the adjusting ring 34 is in contact with the pushing plate 32, and the bottom of the adjusting ring 34 is rotatably connected to a pulling ring 3401, and the surface of the pulling ring 3401 is provided with a The give way opening 3402, the push plate 32 extends into the give way opening 3402, the bottom of the pull ring 3401 is slidably connected with an L-shaped extension rod 35, the extension rod 35 passes through the mounting opening 18 and extends to the bottom of the adjustment rod 29, the surface of the mounting plate 1 is fixedly connected with a stabilizing plate 36, the surface of the stabilizing plate 36 is provided with a stabilizing groove 37 that passes through the stabilizing plate 36, the extension rod 35 passes through the stabilizing groove 37, the surface of the extension rod 35 is fixedly connected with an adjustment plate 38, the surface of the adjustment plate 38 is provided with an inclined adjustment groove 39, the adjustment groove 39 is slidably connected with an L-shaped sliding rod 40, the upper end of the sliding rod 40 is connected to the adjustment rod 29, and the part of the sliding rod 40 inside the adjustment groove 39 can be laterally extended and retracted.

[0041] In the process of preparing the fluff yarn, when the rotation speed of the combing roller 8 needs to be adjusted, the threaded rod 31 is first rotated to drive the adjusting rod 29 to move in the through groove 30. The movement of the adjusting rod 29 drives the sliding rod 40 to move. The bottom of the sliding rod 40 moves in the adjusting groove 39. The adjusting plate 38 moves up or down under the action of the sliding rod 40 and the adjusting groove 39. The adjusting plate 38 drives the extension rod 35 to move synchronously. The stabilizing groove 37 can make the extension rod 35 move stably. The movement of the extension rod 35 drives the pulling ring 3401 to move synchronously with the adjusting ring 34. When the adjusting ring 34 moves, the side surface of the pushing plate 32 is attached. The surface moves, and the winding rod 22 extends or contracts under the action of the adjusting ring 34 and the pushing plate 32, which is beneficial for the winding rod 22 to extend or contract when the speed of the combing roller 8 is adjusted, so that the winding rod 22 can adjust the tension of the fixed yarn 6, and realize the tightness of the fixed yarn 6 when winding the fiber bundle, and ensure the strength of the prepared yarn. When the pushing plate 32 moves, the pushing plate 32 moves in the yielding port 3402, and the pulling ring 3401 is driven to rotate synchronously during the rotation of the pushing plate 32. The fixed yarn 6 passes through the yielding port 3402, and the pulling ring 3401 will not affect the normal winding of the fixed yarn 6.
