Description

Nanofiber applied artificial filler manufacturing apparatus {Manufacturing apparatus to make Artificial filler with nanofiber applied}

The present invention relates to an apparatus for manufacturing artificial fillers to which nanofibers are applied, and more particularly, by electrospinning nanofibers while opening cotton to improve thermal insulation of artificial fillers, while forming only the spinning nozzle and feedroll as conductors to form nanofibers In order to reduce the risk of fire due to electric short when electrospinning, and at the same time to reduce the speed of the artificial filler transferred to the flow rate controller installed adjacent to the end of the transfer pipe, nanofibers are made to ensure sufficient time for electrospinning. It relates to an applied artificial filler manufacturing apparatus.

In general, natural materials such as wool, duck down, goose down, and synthetic fiber materials such as polyester and polyolefin are used as fillers used to provide warmth to clothing or bedding.

In the case of wool, the fiber itself is very soft, and it has good comfort, heat retention, elasticity, hygroscopicity, water repellency, and flame retardancy, making it an ideal fiber for clothing. It is applied to various types of clothing and bedding, but wool is used as a filler. In case of use, there was a problem in that the crimp (crimp) of the wool was tangled from the tip (TIP) to the root (ROOT) direction and pulled to one side.

In addition, in the case of duck down and goose down, the hair flies away, so there is a great loss in the sewing process, and the hair comes out through the sewn hole marks, resulting in poor aesthetics, contamination on other clothes or reduced volume of filler, resulting in reduced thermal insulation and clumping during washing. There were problems such as the need for a process to unfold it, and as the global awareness of animal protection grows, the limitations of its use are gradually being highlighted.

Polyester, polyolefin, etc. are used as synthetic fiber fillers used to solve the problems of these natural materials. Among them, polyester fiber fillers have excellent thermal insulation effect, excellent bulk filling ability, smooth feel, excellent volume restoration, and aesthetic texture. And because of various advantages over other fillers, they are currently being manufactured and sold commercially in large quantities, and polyolefin fibers (especially polypropylene fibers) have advantages in light weight and quick drying compared to polyester fibers.

However, the synthetic fiber filler is not suitable for products that require more heat retention because its heat retention is lower than that of natural materials despite its excellent light weight and quick-drying properties. There is a continuous demand for a filler excellent in heat retention while being light, and development of a filler material having excellent heat retention while being lighter is required.

Nanofibers are fibers that are formed by aggregation of molecules by electrical repulsive force inside a raw material when electricity is applied to a polymer material, and refer to fibers having a thickness of 1,000 nanometers or less.

Conventionally, there has been an attempt to electrospinning the nanofibers on a laminated structure, that is, a nonwoven fabric after opening the synthetic fibers.

However, since the nonwoven fabric is thick, a high voltage must be applied to electrospinning the nanofibers on the nonwoven fabric. This raises the issue that there is a risk of fire.

In addition, since the nonwoven fabric is a laminated structure of opened synthetic fibers, there was also a problem in that the nanofibers did not penetrate deep inside and thus did not show satisfactory thermal insulation.

Furthermore, when the nanofibers are electrospun onto the artificial filler, the speed of the artificial filler transferred is high, so there is a problem that the spinning efficiency of the nanofiber on the surface of the artificial filler is lowered.

Therefore, it is urgently required to develop an artificial filler manufacturing device that can safely spin nanofibers on artificial fillers, increase the spinning efficiency of nanofibers, and increase the thermal insulation of artificial fillers.

1 is a view showing an artificial filler to which nanofibers according to the present invention are applied, and FIG. 2 is a view showing an artificial filler manufacturing apparatus according to the present invention.

It will be described with reference to FIGS. 1 and 2 .

The artificial filler to which the nanofiber is applied according to the present invention is configured to include the opened synthetic fiber cotton (F1) and the nanofiber (F2) spun on the opened synthetic fiber cotton (F1) as shown in FIG. 1 .

In the above-mentioned synthetic fiber cotton (F1), any material that can be used as a filler such as natural fiber cotton, mixed fiber cotton, etc. as well as synthetic fiber cotton used as known fillers such as polyester and polyolefin can be used.

In the present invention, in order to increase the thermal insulation of the artificial filler, the nanofiber was electrospun while opening the synthetic fiber cotton. As a result, a nanofiber coating layer is formed on the surface of the synthetic fiber cotton spread thinly to block the pores of the synthetic fiber cotton.

In the case of electrospun nanofibers on a laminated structure after opening the synthetic fibers, that is, non-woven fabrics, there was a problem in that the thermal insulation was poor because the nanofibers were difficult to penetrate deep inside.

In addition to this, since a high voltage must be applied to electrospinning on the thick nonwoven fabric, there is a risk of fire.

Accordingly, in the present invention, by electrospinning nanofibers before aligning the opened cotton to form a laminated structure, the two conventional problems, namely, the fire occurrence problem due to high voltage application, and the thermal insulation problem due to the shallow penetration depth of the nanofibers are simultaneously solved. did.

As shown in FIG. 2 , the artificial filler manufacturing apparatus according to the present invention includes an opener 100 , a first nanofiber spinning machine 170 , and a storage tank 200 .

The fiber opener 100 is configured to form an artificial filler by introducing the aggregated synthetic fiber cotton and spreading it thinly so that it is separated.

The first nanofiber spinning machine 170 is configured to form a nano-coating layer by electrospinning nanofibers on the surface of the synthetic fiber cotton to be opened by being disposed on one side of the fiber opening machine 100 .

The storage tank 200 is configured to store the artificial filler on which the nano-coating layer is formed.

3 is a view showing the opener 100 according to the present invention, FIG. 4 is a view showing the cylinder drum 111 on which the feed roll 113 according to the present invention is mounted, and FIG. 5 is the present invention. A front view of the first cylinder assembly according to the embodiment.

It will be described with reference to FIGS. 3 to 5 .

The cardamom 100 according to the present invention includes a body 101, a driving unit (not shown), a primary cylinder assembly 110, a pin roll 104 for input, a pin roll 105 for division, and a secondary cylinder assembly 120. ), and an air blower 130 .

The body 101 corresponds to the case of the fiber opener 100, and an inlet 102 through which synthetic fiber cotton is introduced is formed on one side, and an outlet 103 through which the opened artificial filler is discharged is formed on the other side.

The driving unit is configured to provide rotational power to the input pin roll 104 , the primary cylinder assembly 110 , and the split pin roll 105 , and includes a motor and a power transmission device such as a belt.

Since the detailed configuration of the driving unit is a known configuration, a detailed description thereof will be omitted.

The input pin roll 104 with teeth formed on the surface introduces the cotton, which is gathered while rotating, into the body 101 and guides it to the primary cylinder assembly 110 .

The primary cylinder assembly 110 is disposed adjacent to the inlet 102 of the body 101, and a tooth is formed on the surface to rip and separate the incoming cotton while rotating.

A detailed configuration of the primary cylinder assembly 110 will be described.

The primary cylinder assembly 110 includes a cylinder drum 111 , a rotating shaft 112 , a feed roll 113 , and a feed roll cover 114 .

The opened synthetic fiber cotton is wound around the cylinder drum 111 .

The rotating shaft 112 is mounted on one side of the cylinder drum 111 to receive rotational driving force from the driving unit.

The feed roll 113 is formed in a ring shape and is coupled to the outer circumferential surface of the cylinder drum 111 . The feed roll 113 has teeth formed on the outer circumferential surface to tear the synthetic fiber cotton wound around the drum to separate it and spread it.

The feed roll cover 114 is coupled to the outside of the cylinder drum 111 to prevent separation of the feed roll 113 .

A voltage is applied between the feed roll 113 and the first nanofiber spinning machine 170 for electrospinning. At this time, the opened single-layer cotton has a thin thickness, so that the applied voltage can be spun with a small voltage, and the risk of fire is small.

In order to allow electricity to flow only between the feed roll 113 and the first nanofiber spinning machine 170 during electrospinning, only the feed roll 113 and the first nanofiber spinning machine 170 are formed as conductors. The remaining components of the primary cylinder assembly 110, that is, the cylinder drum 111, the rotating shaft 112, and the feed roll cover 114 are formed of a non-conductor, so that electricity does not flow when electrospinning is performed.

The split pin roll 105 is disposed in contact with the primary cylinder assembly 110, and teeth are formed on the surface.

Since the detailed structure of the pin roll 105 for division has the same structure as that of the primary cylinder assembly 110, a detailed description thereof will be omitted.

The split pin roll 105 is to tear the synthetic fiber cotton wound on the surface of the primary cylinder assembly 110 and spread it thinly so as to be separated, and one or more are disposed on the outer peripheral surface of the cylinder drum 111 .

The primary cylinder assembly 110 and the pin roll 105 for division rotate at different rotational speeds. This is to increase the efficiency at which the cotton is torn and separated by inducing a relative speed between the two components, that is, the opening efficiency.

The secondary cylinder assembly 120 is disposed adjacent to the outlet 103 of the body 101 to contact the cylinder drum 111 of the primary cylinder assembly 110 .

The secondary cylinder assembly 120 separates and winds the artificial filler wound on the cylinder drum 111 of the primary cylinder assembly 110 .

Since the detailed structure of the secondary cylinder assembly 120 is the same as that of the primary cylinder assembly 110 , a detailed description thereof will be omitted.

6 is a view for explaining the principle of the air blower 130 to transfer the artificial filler according to the present invention.

It will be described with reference to FIG. 6 .

The air blower 130 is disposed adjacent to the secondary cylinder assembly 120 . The air blower 130 transfers the artificial filler wound around the secondary cylinder assembly 120 to the outlet 103 by spraying air.

Teeth are formed on the outer peripheral surface of the cylinder drum 111 of the secondary cylinder assembly 120 . The opened and separated artificial filler is wound in the tooth and the groove between the teeth.

The air injected from the air blower 130 separates the artificial filler sandwiched in the groove from the secondary cylinder assembly 120 to be transferred to the outlet 103 .

The windbreak plate 140 is formed to protrude from the inner surface of the body 101 of the opener 100 toward the front of the air blower 130 .

The windshield 140 serves to block the air injected by the air blower 130 from flowing to the primary cylinder assembly 110 .

When the air injected by the air blower 130 flows to the primary cylinder assembly 110, not only does the opening by the primary cylinder assembly 110 not occur smoothly, but also in the first nanofiber spinning machine 170 This is because electrospinning cannot be performed smoothly.

The artificial filler manufacturing apparatus according to the present invention is further provided with a conveying pipe 160 and a blower 150 .

The transfer pipe 160 has one end connected to the outlet 103 of the carding machine 100 and the other end connected to the inlet of the storage tank 200 . The transfer pipe 160 is configured to form a flow path through which the artificial filler is moved.

The blower 150 is mounted on one side of the transfer pipe 160 to transfer the artificial filler to the storage tank 200 .

7 is a view showing the artificial filler at each processing position of the opener 100 according to the present invention.

It will be described with reference to FIG. 7 .

The bundled cotton is transferred to the body 101 of the carding machine 100 by the input pin roll 104, and is thinly torn apart as the primary cylinder assembly 110 and the dividing pin roll 105 rotate.

Then, a nanofiber coating layer is formed on the surface of the artificial filler opened by electrospinning by the first nanofiber spinning machine 170 , and it is transferred to the outlet 103 by the secondary cylinder assembly 120 .

The artificial filler formed with the nanofiber coating layer is rolled to form an approximately spherical shape.

In the present invention, the second electrospinning is performed using the second nanofiber spinning machine 180 to increase the heat retention.

The second nanofiber spinning machine 180 is disposed adjacent to the inlet of the storage tank 200 and electrospun nanofibers on the surface of the artificial filler to be transferred to form a nanocoating layer.

The artificial filler transferred through the transfer pipe 160 is transferred to the storage tank 200 at a high speed by the blower 150 . Therefore, if the speed of the artificial filler at the entrance of the storage tank 200 is not properly reduced, electrospinning cannot be smoothly performed by the second nanofiber spinning machine 180 .

Accordingly, in the present invention, a flow rate regulator 190 disposed adjacent to the end of the conveying pipe 160 is provided to reduce the speed of the artificial filler being conveyed.

The flow rate regulator 190 can be proposed in various structures, but it is preferable to form a wire mesh structure in terms of manufacturing convenience and cost.

The present invention relates to an apparatus for manufacturing artificial fillers to which nanofibers are applied, and while opening the cotton, the nanofibers are electrospun to improve the thermal insulation of the artificial fillers, while only the spinning nozzle and the feed roll 113 are formed as conductors to form the nanofibers. At the same time to reduce the risk of fire due to electric short during electrospinning, sufficient time for electrospinning is secured by decelerating the speed of the artificial filler transferred to the flow rate controller 190 installed adjacent to the end of the transfer pipe 160 It relates to an artificial filler manufacturing apparatus to which nanofibers are applied as much as possible.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and it is common in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Various modifications may be made by those having the knowledge of, of course, and these modified embodiments should not be individually understood from the technical spirit or perspective of the present invention.
