Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile fiber technology, and in particular to a co-spinning device for preparing high-performance fibers. Background Technology
[0002] As a type of textile machinery, the co-spinning machine's main function is to effectively blend two or more different types of fibers for textile operations. Co-spinning machines are widely used in the textile production of various fibers such as chemical fibers, acrylic fibers, filaments, low-elasticity yarns, polypropylene, and nylon. They ensure the uniformity of fiber blending, thereby producing yarns or fabrics with specific properties.
[0003] Currently, wet spinning technology is commonly used for co-spinning. First, high-performance microfibers and ordinary chemical fiber raw materials are dispersed and mixed, then heated to create a spinning solution. This solution is extruded from a spinneret to form a fine stream, which solidifies in a coagulation bath to form nascent fibers. These nascent fibers are then plasticized, stretched, and shaped using a co-spinning machine. The shaped fibers are then wound onto a spool, completing the fiber formation process. The resulting yarn has a loose, porous structure, and products made from this yarn possess antibacterial, heat-insulating, warmth-retaining, filtering, and sound-absorbing properties. However, existing co-spinning machines use fiber tensile strength as a standard, with a fixed stretch limit, making them suitable only for a single production line. Different fiber ratios require different production lines, resulting in high costs.
[0004] Based on this, the present invention designs a co-spinning device for high-performance fiber preparation to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a co-spinning device for high-performance fiber preparation, thereby solving the problems in the prior art.
[0006] This utility model is achieved through the following technical solution:
[0007] A high-performance fiber preparation co-spinning device includes, in sequence, a disperser, a spinneret, a solid bath, and a stretching and winding device. The stretching and winding device includes a tension adjustment device mounted on a mounting plate, comprising several vertically fixed slide rods and lead rods. The slide rods and lead rods are evenly spaced, and adjacent slide rods are slidably connected by a slider. The slider is threadedly connected to the lead rod, the lead rod is connected to a reduction motor, and the tension shaft is rotatably connected to the slider.
[0008] The stretching and winding device also includes a winding shaft, which is rotatably connected to a mounting plate.
[0009] The winding shaft has a tension adjustment device on one side and a locking device on the other side. The locking device includes a spoon-shaped handle. The straight arm and the curved arm of the spoon-shaped handle are equipped with anti-slip pads. The straight arm and the curved arm are connected by a fixed shaft, which is rotatably connected to the mounting plate.
[0010] Two sliding rods and a lead screw form a group, and there are at least two groups.
[0011] The two adjacent tensioning shafts are arranged alternately, one above the other.
[0012] This invention has the following advantages: It improves existing co-spinning equipment. The tension adjustment device can adjust the relative distance between two adjacent tension shafts, making it suitable for spinning fibers produced from fiber dopes with different component ratios, resulting in high production efficiency. At the same time, the vertically adjustable tension shaft occupies less space, which can shorten the production line length and save factory space. The horizontally set tension shaft can simultaneously wind multiple strands of spun yarn or fabrics of different widths, so it is not only suitable for wet spinning but also for meltblown spinning, offering high flexibility and wide applicability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the terms "upper", "middle", "outer", "inner", "lower" etc., which indicate orientation or positional relationship, are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, and therefore should not be construed as a limitation of the present utility model.
[0020] The attached figures illustrate specific embodiments of this utility model, such as... Figures 1-3 As shown, this utility model discloses a high-performance fiber preparation co-spinning equipment, which sequentially includes a disperser, a spinneret, a solid bath, and a stretching and winding device. The stretching and winding device includes a tension adjustment device, which is mounted on a mounting plate 1 via a mounting bracket 14. The device includes several vertically fixed slide rods 2 and lead rods 3, which are evenly spaced and arranged in groups of two, with at least two groups. Adjacent slide rods 2 are slidably connected by sliders 4, which are threadedly connected to the lead rods. The lead rods 3 are connected to a reduction motor 6, and a tension shaft 5 is rotatably connected to the sliders 4. Adjacent sliders 4 share the same slide rod 2, and adjacent tension shafts 5 are arranged alternately, one above the other. When the reduction motor 6 drives adjacent lead rods 3 to rotate in opposite directions, the relative distance between the two sliders 2 increases. The relative distance between adjacent tension shafts 5 can be adjusted by calculation to suit the spinning of fiber dopes with different component ratios. The stretching and winding device also includes a winding shaft 7, which is rotatably connected to a mounting plate 1. One side of the winding shaft 7 is provided with a tension adjustment device, and the other side is provided with a locking device. The locking device includes a spoon-shaped handle 8. The straight arm 9 and the curved arm 10 of the spoon-shaped handle are both provided with anti-slip pads 11. The straight arm 9 and the curved arm 10 are connected by a fixed shaft 12, which is rotatably connected to the mounting plate 1. The fixed shaft 12 is a damping shaft.
[0021] When using, refer to Figure 2 The spinning yarn 15 is wound sequentially onto the tensioning shaft 5 and the winding shaft 7. After a batch of spinning yarn is wound, the anti-slip pad 11 is held and the straight arm 9 is pressed down, so that the end of the curved arm 10 is raised, making the anti-slip pad 11 on the curved arm 9 tangent to the spinning yarn roll on the winding shaft 7. After bundling, it is pulled out from the free end of the winding shaft 7 to complete one winding.
[0022] In another embodiment of this utility model, the stretching and winding device of this utility model replaces the traction winding machine of the meltblown spinning machine. The stop block 13 is threaded onto one end of the tensioning shaft 5 to prevent the fabric from shifting during winding. Similarly, the straight arm 9 is pressed down to raise the curved arm 10 to fix the fabric. A glue gun or nail gun is used to fix the fabric to prevent it from loosening. Finally, the fabric is pulled out from the free end of the winding shaft 7 to complete the winding of the fabric.
[0023] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to specific implementation methods.
