Description

Technical Field

[0001] The invention relates to the technical field of spinning processing devices, and in particular to a device and method for preparing nanofiber / short fiber blended yarn. Background Art

[0002] In recent years, the functional application of textiles has attracted wide attention, and nanofibers are one of the main means to give textiles functionalization. Electrospinning has been widely used as a technology that can continuously, quickly and mass-produce nanofibers, but its industrial development has been greatly restricted due to the low strength problem. By mixing nanofibers with short fibers, the textiles are given functionality on the basis of solving the problem that pure nanofibers cannot be spun, which opens up new ideas for the development of nanofibers.

[0003] After searching, the inventions with announcement numbers CN110205724B and CN109322023B announced technical solutions for blending nanofibers with other fibers: 1. Dissolve a polymer in a solvent and stir to prepare an electrospinning solution; 2. The raw materials are opened after being mixed with cotton to obtain a staple fiber aggregate; 3. Start the electrospinning device, and the electrostatic nanofibers generated in the electrospinning nozzle are directly sprayed onto the surface of the staple fiber aggregate at the opening station for uniform mixing to obtain a nanofiber / stub fiber complex; 4. After subsequent processing steps, nanofiber / stub fiber blended yarn is obtained.

[0004] However, the prior art still has the following disadvantages:

[0005] 1. Before blending nanofibers with other fibers, it is necessary to first prepare a short fiber aggregate. However, during the preparation of the short fiber aggregate, a large amount of dust, impurities and residual raw materials remain in the short fiber aggregate, which in turn affects the spinning quality of the subsequent blending of nanofibers and short fibers.

[0006] 2. When making staple fiber aggregates, the staple fiber aggregates tend to gather together, and when the nanofibers are blended with the staple fibers in the later stage, only the nanofibers can be blended with the surface of the staple fiber aggregates. The amount of nanofibers blended into the staple fiber aggregates is relatively small, and the nanofibers and the staple fiber aggregates cannot be fully and evenly blended;

[0007] 3. After the blending is completed, the nanofiber / short fiber blended yarn cannot be dried in time, and the humidity of the blended yarn is too high when it is rolled up, which affects the quality of the blended yarn in the later stage.

[0008] In view of the above problems, the present invention document proposes a device and method for preparing nanofiber / short fiber blended yarn. Summary of the invention

[0009] The present invention provides a device and method for preparing nanofiber / short fiber blended yarn, which solves the shortcomings of the prior art that short fiber aggregates still have a lot of dust, impurities and residual raw materials, the nanofibers and short fiber aggregates cannot be fully and evenly blended, and the blended yarn cannot be dried in time.

A second collecting tank located below the electrostatic spinning nozzle is provided on the top of the workbench. The combed short fiber aggregate enters the U-shaped plate, and the electrostatic spinning liquid stored in the liquid storage tank is passed through the electrostatic spinning nozzle to produce electrostatic nanofiber spinning. Then the electrostatic spinning nozzle directly sprays the electrostatic nanofiber spinning onto the short fiber aggregate to obtain a nanofiber / short fiber complex. The second collecting tank can recycle the scattered nanofiber spinning and use it later.

[0022] The drying assembly includes a drying box fixedly connected to the top of the workbench, the top of the workbench is rotatably connected to two second rotating rollers through a vertical plate, and the two second rotating rollers are located on both sides of the drying box, the top of the drying box is rotatably connected to two first rotating cylinders through the vertical plate, the outer wall of the first rotating cylinder is fixedly sleeved with a plurality of first combing plates, a cavity is provided in the drying box, the inner wall of the cavity on one side away from each other is fixedly connected to a plurality of heating plates, and one side of the drying box is fixedly connected to a blower for blowing air into the cavity.

[0030] S4, starting the first collecting tank, and directly spraying the electrostatic nanofibers generated in the first collecting tank onto the surface of the combed staple fiber assembly to mix them evenly to obtain a nanofiber / stub fiber composite;

[0031] S5. Drying the nanofiber / short fiber composite.

[0032] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0033] In the present invention, a slide plate is slidably connected in the first collecting groove, and a wave plate is fixedly connected to the bottom of the slide plate. A nut block is threadedly sleeved on the outer wall of the reciprocating screw rod, and a convex block matching with the wave plate is fixedly connected to the top of the nut block. A driving motor drives the reciprocating screw rod to rotate, and the reciprocating screw rod is threadedly connected to the nut block. The nut block drives the convex block and the U-shaped bracket to move back and forth along the thread groove of the reciprocating screw rod, and the convex block matches with the wave plate. Then, when the convex block moves, the slide plate can reciprocate up and down, and the slide plate can drive the short fiber aggregate to move up and down to vibrate the short fiber aggregate, which is not only convenient for uniform blending with nanofibers in the later stage, but also convenient for shaking off dust and impurities in the short fiber aggregate.

The inner walls of the first collecting grooves that are away from each other are provided with a lower slide groove and an upper slide groove, and the round rod and the push plate are slidably matched. A fixed column is fixedly connected to an inner wall of one side of the lower slide groove, and a guide plate is rotatably sleeved on the outer wall of the fixed column. The rotation of the reciprocating screw rod can drive the U-shaped bracket and the push plate to reciprocate, so that impurities and raw material residues dropped from the fixed plate are discharged to the outside. At the same time, the round rod cooperates with the upper slide groove on the way back. At this time, the bottom of the push plate is out of contact with the top of the fixed plate, thereby preventing the dust, impurities and residual raw materials on the fixed plate from being driven in the direction of the driving motor when the push plate returns.

[0035] In the present invention, a drying box is fixedly connected to the top of the carding machine, and the top of the drying box is rotatably connected to two first rotating cylinders through a vertical plate, and the outer wall of the first rotating cylinder is fixedly sleeved with a plurality of first carding plates, and a cavity is provided in the drying box, and the inner wall of the cavity on one side away from each other is fixedly connected with a plurality of heating plates, and the blower and the heating plate are started, and the blower blows the hot air in the cavity upward, so as to dry the composite body, thereby preventing the blended yarn from being too high in humidity when winding, thereby affecting the quality of the blended yarn in the later stage;

[0036] In the present invention, a rotating shaft is rotatably connected inside the U-shaped frame, and a first rotating roller is fixedly sleeved on the outer wall of the rotating shaft, and a plurality of second combing plates are fixedly sleeved on the outer wall of the first rotating roller, and a first fan blowing air downward is fixedly connected to the top of the exhaust plate, and a plurality of strip holes are provided in the slide plate. The rotation of the first rotating roller and the second combing plate can comb the dispersed short fiber aggregate, which is convenient for later uniform mixing, and the wind blown by the first fan blows in the direction of the slide plate, and cooperates with the dispersion component to blow the dust, impurities and raw materials remaining in the short fiber aggregate into the first collecting tank through the strip holes, thereby ensuring the cleanliness of the short fiber aggregate.

[0037] In the present invention, the prepared short fiber aggregate can be dispersed and cleaned by the dispersion component and the first fan to prevent the short fiber aggregate from containing too much dust and impurities and affecting the subsequent blending. The dispersed short fiber aggregate can be re-combed by the second combing plate to facilitate the subsequent uniform blending with the nanofibers. In addition, the blended body can be dried in time after the blending is completed to prevent the blended yarn from being too humid when winding, which affects the quality of the blended yarn in the later stage.

A rotating motor 45 is fixedly connected to one side of one of the base plates 41 by bolts, and the output shaft of the rotating motor 45 is fixedly connected to one end of the rotating shaft 42 by a coupling. When the staple fiber aggregate passes through the second rotating cylinder 43, the rotating motor 45 drives the rotating shaft 42, the second rotating cylinder 43 and the bidirectional thread 44 to rotate, and the bidirectional thread 44 touches the staple fiber aggregate. The bidirectional thread 44 can separate the staple fiber aggregate that is gathered together to both sides, thereby dispersing the staple fiber aggregate.

[0072] A method for preparing nanofiber / short fiber blended yarn, using the above-mentioned device for preparing nanofiber / short fiber blended yarn, comprises the following steps:

[0073] S1, dissolving a polymer in a solvent, stirring to prepare an electrospinning solution, and injecting the electrospinning solution into a liquid storage tank 28;

[0074] S2, the raw material short fiber is mixed with cotton, the cotton is opened and cleaned, and is put into the carding machine 1 for carding to obtain a short fiber aggregate;

[0075] S3, vibrating the staple fiber aggregate, then removing the dust and impurities contained therein, and then combing the vibrated staple fiber aggregate again;

[0076] S4, starting the first collecting tank 3, the electrostatic nanofibers generated in the first collecting tank 3 are directly sprayed onto the surface of the combed staple fiber assembly, and are evenly mixed to obtain a nanofiber / stub fiber composite;

[0077] S5. Drying the nanofiber / short fiber composite.

[0078] Working principle: the raw material staple fiber and cotton are put into the carding machine 1, and the staple fiber aggregate is obtained after the carding machine 1 combs the raw material. The staple fiber aggregate moves to the left, and when it passes through the second rotating cylinder 43, the rotating motor 45 is started, and the output shaft of the rotating motor 45 drives the rotating shaft 42, the second rotating cylinder 43 and the bidirectional thread 44 to rotate, and the bidirectional thread 44 touches the staple fiber aggregate. With the rotation of the second rotating cylinder 43 and the bidirectional thread 44, the bidirectional thread 44 can separate the staple fiber aggregate gathered together to both sides, and then disperse the staple fiber aggregate. When the staple fiber aggregate moves to the left to the top of the slide 7, the driving motor 14 is started to drive the reciprocating screw rod 10 to rotate, and the reciprocating screw rod 10 is threadedly connected to the nut block 11, and the nut block 11 drives The protrusion 12 and the U-shaped bracket 13 reciprocate back and forth along the thread groove of the reciprocating screw rod 10, and the protrusion 12 cooperates with the wave plate 9, and then when the protrusion 12 moves, the slide plate 7 can reciprocate up and down, and the slide plate 7 can drive the staple fiber aggregate to move up and down, and further disperse the staple fiber aggregate, and then start the first fan 19, and the wind blown by the first fan 19 blows in the direction of the slide plate 7, and the wind force can blow the dust, impurities and raw materials remaining in the staple fiber aggregate into the first collecting tank 3 through the strip hole 39, and the U-shaped bracket 13 can drive the push plate 20 to move, and the push plate 20 pushes the dust, impurities and residual raw materials on the fixed plate 8 toward the discharge port 26, and when the U-shaped bracket 13 drives the push plate 20 to move, the round rod 21 moves along the lower groove When the U-shaped bracket 13 moves to the end position, the round rod 21 is out of contact with the guide plate 25, and the guide plate 25 is reset clockwise under the action of its own gravity. Then the reciprocating screw 10 drives the push plate 20 and the round rod 21 to move back through the U-shaped bracket 13, and the round rod 21 enters the upper slide groove 23 through the guidance of the guide plate 25. At this time, the bottom of the push plate 20 is out of contact with the top of the fixed plate 8, thereby preventing the push plate 20 from driving the dust, impurities and residual raw materials on the fixed plate 8 toward the driving motor 14 when returning. When the staple fiber aggregate moves into the U-shaped bracket 4, the reciprocating screw 10 passes through the first synchronous wheel 15, the second synchronous wheel 16 and the synchronous belt 17. The cooperation of the first rotating roller 6 and the second combing plate 38 drives the rotation, and the second combing plate 38 combs the dispersed staple fiber aggregate, and then the staple fiber aggregate enters the U-shaped plate 27, and the electrostatic spinning liquid stored in the liquid storage tank 28 is spun into electrostatic nanofibers generated by the electrostatic spinning nozzle 29, and then the electrostatic spinning nozzle 29 directly sprays the electrostatic nanofibers onto the staple fiber aggregate to obtain a nanofiber / stub fiber composite, and then the composite is guided by the second rotating roller 31 and is located at the top of the drying box 32, and the blower 35 and the heating plate 34 are started, and the blower 35 blows the hot air in the cavity 33 upwards, so as to dry the composite, so as to prevent the humidity of the blended yarn from being too high when winding, thereby affecting the quality of the blended yarn in the later stage.
