Description

Technical Field

[0001] The present invention relates to the technical field of fiber manufacturing, in particular to a cooling and winding device for manufacturing hollow bicomponent fibers and a method thereof. Background Art

[0002] Bicomponent fibers, also known as composite fibers, are composed of two different fiber-forming polymers or similar fiber-forming polymers with different properties. Since the two components contained in this fiber complement each other, the performance of the composite fiber is usually better than that of conventional synthetic fibers, and it has a wide range of uses. Composite fibers can be divided into two categories according to their morphology, namely, double-layer and multi-layer types. The double-layer type includes parallel type and skin-core type, while the multi-layer type includes parallel multi-layer type, radial type, multi-core type, wood grain type, embedded type, multi-island type and cloud type. The forming method of bicomponent fibers can adopt a composite spinning method to make parallel type, skin-core type and multi-core type composite fibers; or a blended spinning method can be adopted to make sea-island type composite fibers. By utilizing the different properties of the two component polymers, three-dimensional permanent curled fibers, thermal bonding fibers (such as ES fibers), conductive fibers, etc. can be made;

[0045] The cooling and winding device for manufacturing hollow bicomponent fibers also includes:

[0046] The stirring device 7 is provided to stir the hollow bicomponent fibers agglomerated in the inner cavity of the cooling box 4, so that the heat in the hollow bicomponent fibers that still have residual temperature is dissipated during the stirring of the hollow bicomponent fibers, thereby achieving a cooling effect.

The end of the second support rod 71 is fixedly connected to a first servo motor 72, and the output end of the first servo motor 72 is fixedly connected to a first rotating rod 73, which passes through the cooling box 4. The arrangement of the first servo motor 72 and the first rotating rod 73 can make the hollow bicomponent fibers in the inner cavity of the cooling box 4 start to rotate in the inner cavity of the cooling box 4 and make the attachment device 8 start to rotate.

[0047] The stirring device 7 further includes a first fixing plate 74, which is fixedly connected to the inner wall of the cooling box 4. A first limiting ring 75 is fixedly connected to the end of the first fixing plate 74. A rotating block 76 is fixedly connected to the end of the first rotating rod 73 away from the first servo motor 72.

The second servo motor 92 starts to work, thereby driving the first rolling column 94 to start rotating. By moving the sliding block 99 in the inner cavity of the track frame 98, the distance between the second rolling column 913 and the first rolling column 94 is changed, thereby changing the thickness of the hollow bicomponent fiber roll. Under the rolling of the first rolling column 94 and the second rolling column 913, the hollow bicomponent fiber is rolled into a cake, which facilitates the rolling of the hollow bicomponent fiber.

[0053] A cooling and winding method for producing hollow bicomponent fibers comprises the following steps:

[0054] Step 1: Before rolling the hollow bicomponent fibers, the still warm hollow bicomponent fibers are divided into apple-sized balls. The apple-sized balls are then poured from the opening of the hopper 5 into the inner cavity of the cooling box 4.

[0055] Step 2: After the hollow bicomponent fibers enter the inner cavity of the cooling box 4, the first servo motor 72 is connected to a power source and turned on. The first rotating rod 73 is driven by the first servo motor 72 to rotate, and the first striking rod 713 strikes the hollow bicomponent fiber mass in the inner cavity of the cooling box 4, thereby dispersing the hollow bicomponent fibers into a loose state.

[0056] Step 3: As the first rotating rod 73 continues to rotate, the breaking device 78 cooperates with the first striking rod 713 to strike the clumped and stuck hollow bicomponent fibers. After ten minutes of striking, the clumped hollow bicomponent fibers are completely broken up and eventually fall out from the gaps between the partition rods 10.

[0057] Step 4: After the hollow bicomponent fibers become loose and uniform, the second servo motor 92 is connected to a power source and turned on. The second servo motor 92 starts to work, thereby driving the first rolling column 94 to start rotating.

[0058] Step 5: By moving the sliding block 99 in the inner cavity of the track frame 98, the distance between the second rolling column 913 and the first rolling column 94 is changed, thereby changing the thickness of the hollow bicomponent fiber roll. Under the rolling of the first rolling column 94 and the second rolling column 913, the hollow bicomponent fiber is rolled into a cake, which facilitates the rolling of the hollow bicomponent fiber.
