[0032] As can be seen from the background technology, the existing fiber opening methods still need to be improved.

[0033] A fiber opening method is now analyzed, and the process steps mainly include: using a high-speed rotating beater to hit the fibers to loosen the fibers.

[0034] If the beaters are used to hit the fibers too many times, it is easy to cause fiber damage and impurities to break, resulting in an increase in fiber defects; if the beaters are used too few times, the fiber loosening degree is low and more impurities remain. Therefore, it is difficult to achieve the ideal fiber loosening effect by using beaters to hit the fibers.

[0035] The inventor has studied the above-mentioned problem, and through creative work, the inventor has noticed that opening the fibers using a fiber opening system including an initial opening component and a roller device can help improve the fiber fluffiness.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] The following first introduces in detail the fiber opening system suitable for the fiber opening method provided by the present invention.

[0038] Figure 1 Schematic diagram of the structure of a fiber opening system 100 according to an embodiment of the present invention.

[0039] refer to Figure 1 A fiber opening system 100 includes: a primary opening component 200; a roller device 300, connected to the primary opening component 200 via a first conveying pipeline 410; and a baler 500, connected to the roller device 300 via a second conveying pipeline 420.

[0040] The primary opening assembly 200 is suitable for primary opening of fibers. The roller device 300 is suitable for fine opening of fibers after primary opening. The baler 500 is suitable for baling fibers after fine opening.

[0041] Figure 2 It is a schematic structural diagram of a primary opening component 200 of a fiber opening system 100 according to an embodiment of the present invention.

[0042] refer to Figure 2 In this embodiment, the initial opening component 200 includes a slanted nail curtain 210 and a beater 220. The slanted nail curtain 210 transports fibers along a first predetermined path. The beater 220 is arranged on the first predetermined path and contacts the surface of the slanted nail curtain 210. The surface of the slanted nail curtain 210 has a plurality of combing nails 211. The beater 220 includes a roller 221 and a plurality of needle teeth 222 arranged on the surface of the roller 221.

[0043] When the oblique nail curtain 210 is conveying fibers along the first predetermined path, the combing nails 211 can comb the fibers to loosen the fibers and improve the initial opening effect.

[0044] The initial opening component 200 further includes a conveying belt 231 , and the conveying belt 231 is suitable for conveying fibers to the oblique nail curtain 210 .

[0045] In this embodiment, the initial opening and loosening component 200 also includes: a third rotating wheel 230 and a fourth rotating wheel 240 arranged at intervals, the first predetermined path has a relative input end and an output end, the third rotating wheel 230 is arranged on the input end, the fourth rotating wheel 240 is arranged between the input end and the output end, the conveying belt 231 is sleeved on the third rotating wheel 230 and the fourth rotating wheel 240; a fifth rotating wheel 250, the fifth rotating wheel 250 is arranged on the output end, the oblique nail curtain 210 is surrounded by a ring, and the oblique nail curtain 210 is sleeved on the fourth rotating wheel 240 and the fifth rotating wheel 250.

[0046] Figure 2 The straight line with an arrow in the middle indicates the fiber conveying direction.

[0047] In this embodiment, the conveying belt 231 is in a ring shape. The third rotating wheel 230 and the fourth rotating wheel 240 are arranged at intervals on the same horizontal plane, and the conveying belt 231 conveys the fiber along the horizontal plane.

[0048] In this embodiment, the fifth rotating wheel 250 is located obliquely above the fourth rotating wheel 240. The oblique nail curtain 210 conveys the fiber upward along the inclined surface. A first angle α is formed between the conveying belt 231 and the oblique nail curtain 210, and the first angle α is an obtuse angle.

[0049] In this embodiment, the combing nails 211 are arranged in rows on the entire surface of the oblique nail curtain 210, and the spacing between adjacent rows is equal. The spacing between adjacent combing nails 211 in the same row is equal.

[0050] In this embodiment, the combing pins 211 are made of metal.

[0051] The oblique nail curtain 210 transports the fibers upward along the inclined surface. The fibers on the surface of the oblique nail curtain 210 tend to move downward along the inclined surface under the action of gravity. The fibers are combed by the combing nails 211 in the process of rolling downward relative to the surface of the oblique nail curtain 210, so that the combing nails 211 can loosen the fibers.

[0052] It should be noted that, since the speed at which the fiber rolls downward relative to the surface of the oblique nail curtain 210 is lower than the speed at which the oblique nail curtain 210 moves upward along the inclined surface, the fiber can eventually reach the output end of the first predetermined path under the conveyance of the oblique nail curtain 210 .

[0053] The surface of the roller 221 is fixed with a plurality of fixing strips (not shown) arranged at intervals along the circumferential direction. The fixing strips extend along the length direction of the roller 221, extending from one end of the roller 221 to the other end. The needle teeth 222 are arranged at intervals on the fixing strips. The roller 221 rotates so that the needle teeth 222 on the fixing strips contact the surface of the oblique nail curtain 210 in turn.

[0054] When the fibers are transported to the beater 220, the needle teeth 222 on the surface of the drum 221 of the beater 220 extend into between adjacent combing pins 211, and the needle teeth 222 and the combing pins 211 move relative to each other, so that the needle teeth 222 can further loosen the fibers between adjacent combing pins 211 and promote the separation of impurities between the fibers from the fibers.

[0055] In this embodiment, the needle teeth 222 are made of metal.

[0056] Combined with reference Figure 1 and Figure 2 In this embodiment, the fiber opening system 100 also includes: a first metal detector 610, which is arranged on the first conveying pipeline 410 and is located between the initial opening component 200 and the roller device 300.

[0057] During the initial opening process, the combing pins 211 or the needle teeth 222 may break and then be mixed into the fiber. Since the materials of the combing pins 211 and the needle teeth 222 are both metal, the first metal detector 610 can detect whether there are broken combing pins 211 or needle teeth 222 in the fiber by detecting whether there is metal material in the fiber after the initial opening, so as to ensure that the broken combing pins 211 or needle teeth 222 in the fiber can be removed in time, and prevent the broken combing pins 211 or needle teeth 222 from moving with the fiber and causing damage to the roller device 300 during the fine opening process. In addition, the first metal detector 610 can also detect other metal impurities in the fiber, which helps to improve the quality of the fiber.

[0058] Figure 3 It is a schematic structural diagram of a roller device 300 of a fiber opening system 100 according to an embodiment of the present invention.

[0059] refer to Figure 3 , the first delivery pipeline 410 (reference Figure 1) transports the fiber along a second predetermined path. The roller device 300 comprises a feeding roller 310 and a cotton opening roller 320 which are arranged front and back on the second predetermined path. The feeding roller 310 is suitable for transporting the fiber to the cotton opening roller 320, and the cotton opening roller 320 is suitable for finely opening the fiber.

[0060] The fibers are transported to the opening roller 320 by the feeding roller 310 for fine opening, which facilitates the control of the feeding process and reduces the risk of fiber blockage at the opening roller 320 .

[0061] In this embodiment, an arc plate 330 is provided on the periphery of the cotton opening roller 320. The arc plate 330 has a plurality of combing teeth (not shown in the figure) on the surface facing the cotton opening roller 320. The combing teeth separate the fibers that move to the gap between the arc plate 330 and the cotton opening roller 320, making the fibers more fluffy and further removing impurities between the fibers.

[0062] In this embodiment, the gap between the arc plate 330 and the cotton opening roller 320 is 1 mm to 1.5 mm.

[0063] In this embodiment, the roller device 300 further includes: a first motor 340; a first rotating wheel 341 disposed on the motor shaft of the first motor 340; and a first annular belt 351 sleeved on the first rotating wheel 341 and the outer circumference of the cotton feeding roller 310.

[0064] The first motor 340 drives the first rotating wheel 341 to rotate, and the first endless belt 351 moves and drives the cotton feeding roller 310 to rotate. By regulating the first motor 340, the cotton feeding roller 310 can be controlled to rotate clockwise.

[0065] In this embodiment, the roller device 300 further includes: a first auxiliary rotating wheel 381 , which is disposed on the surface of the first endless belt 351 and is suitable for modulating the shape of the first endless belt 351 .

[0066] In this embodiment, the roller device 300 also includes: a rotating shaft 360, fixed on the center of the cotton feeding roller 310; a second rotating wheel 342, arranged close to the cotton feeding roller 310; a second annular belt 352, the second annular belt 352 is sleeved on the second rotating wheel 342 and the rotating shaft 360; a recycled cotton roller member 370, the outer surface of the recycled cotton roller member 370 is in contact with the surface of the second annular belt 352, and the second annular belt 352 drives the recycled cotton roller member 370 to rotate.

[0067] The rotating shaft 360 rotates together with the cotton feeding roller 310. Since one end of the second endless belt 352 is sleeved on the rotating shaft 360, the rotating shaft 360 rotates to drive the second endless belt 352 to move, and the second endless belt 352 further drives the cotton recycling roller member 370 to rotate.

[0068] The cotton opening roller 320 is located on one side of the cotton feeding roller 310 , and the cotton returning roller member 370 is located on the other side of the cotton feeding roller 310 .

[0069] In this embodiment, the cotton opening roller 320 is located on the right side of the cotton feeding roller 310, and the cotton recycling roller member 370 is located on the left side of the cotton feeding roller 310. When the cotton feeding roller 310 rotates clockwise, the fibers at the cotton feeding roller 310 are transported toward the cotton opening roller 320, and when the cotton feeding roller 310 rotates counterclockwise, the fibers at the cotton feeding roller 310 are transported toward the cotton recycling roller member 370.

[0070] The return cotton roller member 370 helps to reduce the risk of cotton blockage caused by excessive fibers to be finely opened at the cotton opening roller 320.

[0071] At the cotton feeding roller 310, by adjusting the rotation direction of the cotton feeding roller 310, part of the fibers can be transferred to the cotton opening roller 320 for fine opening, and the other part of the fibers can be transferred to the return cotton roller member 370 via the second endless belt 352. After the fiber congestion at the cotton opening roller 320 is improved, the fibers at the return cotton roller member 370 are returned to the cotton feeding roller 310 via the second endless belt 352 and then reach the cotton opening roller 320 for fine opening. Therefore, the return cotton roller member 370 helps to reduce the risk of cotton blockage.

[0072] In this embodiment, the outer surface of the recycled cotton roller member 370 has a plurality of combing needles 371. When the fibers transmitted to the recycled cotton roller member 370 rotate with the recycled cotton roller member 370, the combing needles 371 further loosen the fibers to improve the uniformity of fiber mixing.

[0073] In this embodiment, the roller device 300 further includes: a second auxiliary rotating wheel 382 , and the second annular belt 352 is not only sleeved on the second rotating wheel 342 and the rotating shaft 360 , but also sleeved on the second auxiliary rotating wheel 382 .

[0074] refer to Figure 1In this embodiment, the fiber opening system 100 also includes: a fan 700, which is arranged on the second conveying pipeline 420, the first conveying pipeline 410 and the second conveying pipeline 420 are connected, and the fan 700 is suitable for conveying wind into the first conveying pipeline 410 and the second conveying pipeline 420.

[0075] The fibers after initial opening are moved along the first conveying pipeline 410 and the second conveying pipeline 420 under the action of wind delivered by the blower 700 .

[0076] The fiber opening system 100 further includes: a second metal detector 620 disposed on the second conveying pipeline 420 .

[0077] The second metal detector 620 can detect whether there are metal impurities in the fibers after fine opening, so as to facilitate timely removal of metal impurities, prevent metal impurities from being mixed into the fibers and affecting the fiber quality, and avoid metal impurities from moving with the fibers and causing damage to the baler 500 during the baling process.

[0078] Figure 4 4 is a flow chart of a fiber opening method according to an embodiment of the present invention.

[0079] Reference Figure 4 The present invention also provides a fiber opening method implemented by using the above-mentioned fiber opening system 100.

[0080] Execute step S11 to perform preliminary opening of the fibers using the preliminary opening component 200 .

[0081] In this embodiment, the fiber is a chemical fiber with a purity of 100%. The chemical fiber material is light and thin, and is not easy to form a ball after washing.

[0082] Combined with reference Figure 2 and Figure 4 In this embodiment, the initial opening component 200 includes a slanted nail curtain 210 and a beater 220. The slanted nail curtain 210 transports the fiber along a first predetermined path. The beater 220 is arranged on the first predetermined path and contacts the surface of the slanted nail curtain 210. The surface of the slanted nail curtain 210 has a plurality of combing nails 211. The beater 220 includes a roller 221 and a plurality of needle teeth 222 arranged on the surface of the roller 221.

[0083] In this embodiment, during the initial opening process, the combing pins 211 and the needle teeth 222 comb the fibers.

[0084] When the fibers are transported to the beater 220, the needle teeth 222 on the surface of the drum 221 of the beater 220 extend into between adjacent combing pins 211, which can further loosen the fibers between adjacent combing pins 211 and destroy the connection between the fibers and between the fibers and impurities, thereby achieving the purpose of further loosening the fibers and removing impurities; thus, the combing pins 211 and the needle teeth 222 cooperate with each other, which helps to improve the combing effect on the fibers in the initial opening stage.

[0085] In other embodiments, the needle teeth 222 can also strike the fibers transported to the beater 220 to loosen the fibers.

[0086] In this embodiment, the speed of the oblique nail curtain 210 is 1200 rpm to 1500 rpm, so as to ensure the pre-opening effect of the oblique nail curtain 210 on the fibers.

[0087] In this embodiment, before the fibers are initially opened, the method further includes: spraying an antistatic agent on the surface of the fibers.

[0088] In the case of low humidity, the fiber is prone to generate static electricity. Spraying antistatic agent helps to suppress the generation of static electricity.

[0089] In this embodiment, during the initial opening of the fibers, feeding and stopping of feeding are performed cyclically, wherein the feeding operation time is 3s to 5s and the feeding stop time is 3s to 5s, so as to reduce the risk of cotton blockage.

[0090] refer to Figure 4 After the initial opening, step S12 is executed to transport the fibers along the second predetermined path through the first conveying pipeline, and the fibers are finely opened using the roller device 300.

[0091] Combined with reference Figure 3 and Figure 4 In this embodiment, the roller device 300 includes a cotton feeding roller 310 and a cotton opening roller 320 which are arranged front and back on the second predetermined path.

[0092] The feeding roller 310 is suitable for conveying the fibers to the opening roller 320, and the opening roller 320 is suitable for finely opening the fibers to decompose the bundled fibers into single fibers and remove fine impurities remaining in the fibers so as to fully mix the single fibers.

[0093] The fibers are transported to the opening roller 320 by the feeding roller 310 for fine opening, which facilitates the control of the feeding process and reduces the risk of fiber blockage at the opening roller 320 .

[0094] In this embodiment, in order to prevent the broken combing nails 211 or the needle teeth 222 from being mixed into the fibers and avoid introducing other metal impurities into the fibers, after the initial opening and before the fine opening, it also includes: performing a first metal impurity detection on the fibers.

[0095] In this embodiment, an arc plate 330 is provided on the periphery of the cotton opening roller 320. The arc plate 330 has a plurality of combing teeth (not shown in the figure) on the surface facing the cotton opening roller 320. The gap between the arc plate 330 and the cotton opening roller 320 is 1 mm to 1.5 mm, thereby ensuring the combing teeth's pulling effect on the fibers passing through the gap.

[0096] In this embodiment, the first conveying pipeline conveys the fibers by means of wind force generated by the fan 700, and the speed of the fan 700 is 1800 rpm to 2000 rpm, thereby reducing the risk of cotton blockage while ensuring the fiber opening effect.

[0097] In this embodiment, the speed of the opening roller 320 is 1500 rpm to 1800 rpm, which improves the fiber fluffiness and reduces fiber damage.

[0098] In this embodiment, the speed of the cotton feeding roller 310 is 5 m / min to 7 m / min. On the one hand, it ensures sufficient fiber supply at the cotton opening roller 320; on the other hand, it reduces the risk of blockage at the cotton opening roller 320.

[0099] In this embodiment, in order to reduce the risk of cotton blocking, feeding and stopping of feeding are cyclically performed during the fine opening of fibers, wherein the feeding operation time is 3s to 5s, and the feeding stop time is 3s to 5s.

[0100] After fine opening, step S13 is performed to pack the fibers.

[0101] In this embodiment, in order to timely remove the metal impurities that may be introduced into the fibers during the fine opening process, after the fine opening and before packaging, the process further includes: performing a second metal impurity detection on the fibers.

[0102] The fiber opening method can obtain a bulkiness of 550in 3 / 30g~570in 3 / 30g of fiber.

[0103] In summary, the fiber opening method is helpful to improve fiber bulkiness, remove impurities, and ensure uniform fiber mixing. The fiber is used as a clothing filling material, and has a good warmth-keeping effect due to its good bulkiness.

[0104] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
