Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a fiber mixing device for hemp-cotton blended yarn. Background Art

[0002] With the rapid development of social economy and the continuous improvement of living standards, people's pursuit of clothing fabrics has gradually developed in the direction of health and comfort. With the continuous development of textile technology, blended fabrics have been widely used in clothing, home furnishing and other fields due to their excellent performance. Blended fabrics refer to the mixing of two or more fibers to form a new fiber fabric. Blended fabrics are woven with blended yarns. Blended yarns refer to yarns made by mixing two or more different fibers in a certain proportion, such as polyester-cotton blended yarns, polyester-viscose blended yarns, cotton-linen blended yarns, etc. In recent years, hemp-cotton blended fabrics have been widely used in various clothing fabrics due to their advantages such as breathability, moisture absorption, natural antibacterial and comfortable wearing. In terms of appearance, it not only maintains the unique rough and crisp style of linen fabrics, but also has the soft characteristics of cotton fabrics, improving the shortcomings of linen fabrics that are not fine and clean and easy to pilling. It has a firm and smooth texture, feels light and soft, and is natural and environmentally friendly. It has become the first choice for light clothing fabrics in summer and is loved by consumers.

[0003] Hemp blended fabrics are generally blended with 55% hemp and 45% cotton or 50% hemp and 50% cotton respectively. They can also be blended with 30% hemp and 70% cotton. The properties of yarns and fabrics obtained with different blending ratios are slightly different. Before spinning, hemp and cotton blended yarns need to be fully mixed with hemp fibers and cotton fibers, and then spinning begins. At present, hemp and cotton color spinning manufacturers all use manual mixing and manual packaging. In the actual production process, hemp fibers and cotton fibers are placed in the disc of the disc grab bag machine according to the process requirements. First, the hemp fibers and metal impurities in the fibers are manually picked, and then they are manually mixed and then transported to the packaging machine for packaging. Due to the special structure of hemp fibers, there are many impurities such as fine dust and sand. Direct mixing can easily bring impurities into the mixed fibers. In addition, due to the rough texture of hemp fibers themselves, the efficiency of artificially mixing hemp and cotton fibers is low, and it is not easy to mix hemp and cotton fibers evenly.

[0004] In summary, the uniformity of the mixing of the two fibers has a great influence on the mechanical properties of the blended yarn and the final wearability of the fabric, and the incorporation of impurities directly affects the yarn quality of the blended yarn. Therefore, how to achieve uniform mixing of hemp fiber and cotton fiber, avoid the influence of hemp fiber impurities, improve the yarn quality of the blended yarn, and improve the fiber mixing efficiency and mixing quality under the premise of effectively reducing the labor intensity of workers has become a difficult problem that technicians in the field of hemp-cotton blended yarn production need to solve urgently.

[0022] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown, a fiber mixing device for hemp-cotton blended yarn includes a disc plucking machine 1 and a cotton conveying pipeline 2 for conveying hemp fibers and cotton fibers, and a cotton feeding fan 3 is provided on the cotton combing pipeline 2. The disc plucking machine 1 grabs hemp fibers and cotton fibers according to the process ratio of hemp fibers and cotton fibers and continuously mixes the hemp fibers and cotton fibers during transportation in the cotton conveying pipeline 2, and performs a premixing process on the two fibers during transportation; the mixed hemp fibers and cotton fibers are conveyed through the cotton conveying pipeline 2, which solves the problem of low efficiency of manual conveying of hemp-cotton mixed fibers and the easy scattering of hemp-cotton fibers into the air, which not only harms the health of employees but also causes serious environmental pollution.

[0024] like Figure 2 As shown, a mixing mechanism 5 for mixing hemp fiber and cotton fiber is connected to the discharge port 4 of the combing pipe 2, and the mixing mechanism 5 includes a mixing bin 7 with a discharge port 6, and an impurity separation mechanism 8 arranged at the bottom of the mixing bin 7. The mixing bin 7 includes a cylindrical bin wall 10 with a mixing cavity 9, a cover plate 11 arranged on the top of the cylindrical bin wall 10, and the impurity separation mechanism 8 is fixedly connected to the bottom of the cylindrical bin wall 10. The discharge port 4 of the combing pipe 2 extends into the mixing cavity 9 through the cover plate 11. In order to improve the mixing efficiency and mixing quality of the fibers in the mixing bin 7, a blower 12 for providing reverse blowing into the mixing bin 7 and a cotton suction fan 13 for discharging the mixed fibers through the mixing bin 7 are arranged at the discharge port 6 of the mixing bin. The blower 12 delivers air to the discharge port 6 through the pipeline, and blows the hemp fiber and cotton fiber materials in the mixing chamber 9 to confuse them, thereby helping to improve the uniformity and mixing efficiency of the fiber mixing. Under the premise of not affecting the processes of fiber conveying, mixing, and discharging, the air volume and opening and closing conditions of the cotton feeding fan 3, the blower 12, and the cotton suction fan 13 can be adjusted according to actual conditions. This technology can be controlled by a controller, and those skilled in the art can make conventional settings according to actual needs. The specific signal control is not described in detail in this utility model.

[0025] like Figure 2 , 3As shown in Figure 4, a rotating shaft 14 for opening, removing impurities and mixing the mixed hemp fiber and cotton fiber is provided in the mixing bin 7 along the height direction of the mixing bin 7, and a motor 15 for driving the rotating shaft to rotate is provided. A plurality of stirring components 16 are provided on the surface of the rotating shaft 14 along the axial direction of the rotating shaft 14, and a plurality of mixing rods 17 are provided on the cylindrical bin wall 10 of the mixing bin 7 and extend in the direction of the rotating shaft 14 and are arranged to cross with the stirring components 16. The rotating shaft 14 includes a rod body 18, and a first end cover 19 and a second end cover 20 respectively arranged at the top and bottom of the rod body 18, and the stirring components 16 are symmetrically arranged on the rod body 18 along the central axis of the rod body 18 or arranged at 60 degrees to each other on the rod body 18. The rotating shaft 14 passes through the cover plate 11 and is connected to the motor 15 arranged on the cover plate 11. The stirring member 16 is welded by two straight rods 19 and a plurality of arc-shaped rods 21 disposed between the two straight rods 19, and a fan-shaped structure is formed between the two straight rods 19 and the arc-shaped rods 21. At present, the existing technology mostly adopts a single rod body. Since various fibers are often entangled after mixing, the traditional single rod body is relatively smooth, and the smooth surface structure is difficult to restrain the fibers, and the loosening and collision effects are not good, and it cannot give more pulling and tearing forces to the entangled fibers. The fan-shaped structure of the utility model has a large horizontal area and a large number of rods, which can attach and push more fiber groups to rotate. In the process of making the mixing rod 17 cross the fan-shaped structure during rotation, the intersection area and overlapping time of the fan-shaped structure and the mixing rod 17 are increased, and more fiber groups can be brought into contact with the mixing rod 17 within a unit number of rotations, so that the fiber loosening is more uniform and the mixing is more sufficient. And due to the number and structure of the rods, the fiber clusters can be retained in the gaps between the rods. When they come into contact with the mixing rod 17, they can provide a certain tearing force and collision force to the retained fiber clusters, so that the hemp fibers are affected by the collision force during the stirring process, making the hemp fibers relatively loose, which helps to improve the problem of the roughness of the hemp fibers.

[0026] like Figure 3 , 5As shown, in order to further improve the mixing efficiency and uniformity between hemp fiber and cotton fiber, and improve the defect of hemp fiber being rough and hard, the utility model is provided with a position adjustment mechanism 22 on the rotating shaft 14 for adjusting the spacing between the stirring member 16 and the mixing rod 17. The position adjustment mechanism 22 includes an adjustment groove 23 continuously opened on the surface of the rod body 18 along the axial direction of the rod body 18, and a plurality of sliders 24 for fixing the stirring member 16 are provided in the adjustment groove 23, and a threaded adjustment rod 25 threadedly connected to the slider 24 for driving each stirring member 16 to rise or fall synchronously. An adjustment end 26 for rotating the threaded adjustment rod 25 is provided on the first end cover 19, and the bottom is rotatably connected to the second end cover 20. The specific connection structure of the stirring member 16 and the rotating shaft 14 is: a connecting plate 26 is provided at the end of the two straight rods 19, and the fan-shaped structure is bolted to the slider 24 through the connecting plate 27.

[0027] Please refer to Figure 2 In the utility model, the threaded adjustment rod 25 is driven to rotate by rotating the adjustment end 26. Under the push of the threaded structure, the slider 24 is synchronously raised and lowered with the rotation of the threaded adjustment rod 25. The stirring member 16 can adjust the vertical spacing between the stirring member 16 and the mixing rod 17 as the slider 24 rises or falls. When the fiber length is small, the stirring member 16 can be adjusted to reduce the spacing between the stirring member 16 and the mixing rod 17 to improve the mixing and opening effect, increase the probability of fiber stress and collision, and improve the problem of hemp fiber coarseness and hardness. When the fiber length is large, the spacing is appropriately increased to avoid fiber entanglement. The number of threaded adjustment rods 25 can be set according to the actual number of vertical settings of the stirring member 16. Taking the utility model as an example, when two groups are symmetrically set or set at 60° to each other, two or three threaded adjustment rods 25 can be set. Different threaded adjustment rods 25 can realize separate spacing adjustment without affecting each other. In theory, multi-level precision adjustment can be achieved, which has extensive and practical industrial value for the preparation of hemp fiber mixed with other fibers.

[0028] In order to improve the overall stability of the position adjustment mechanism 22 and reduce the noise when the shaft 14 rotates, the size of the slider 24 and the adjustment slot 23 should be as small as possible, and lubricating oil should be applied for protection to improve the accuracy of adjustment. In order to reduce costs and reduce the weight of the rod body 18, the rod body 18 in the utility model is made of a hollow steel pipe. Of course, the structure can be a solid rod structure according to actual needs.

[0029] like Figure 2 , 6As shown in Figures 7 and 8, the impurity separation mechanism 8 includes a chassis 28 with a central opening, a net body 30 for leaking impurities 29 is fixed at the central opening, a support and protection plate 31 for supporting the rotating shaft 14 and preventing the impurities 29 from being lifted is arranged between the chassis 28 and the bottom of the mixing bin 7, and a collecting plate 32 for storing the impurities 29 is arranged at the bottom of the chassis 28. The support and protection plate 31 includes an annular base plate 33, a support portion 34 for supporting the rotating shaft 14 is arranged at the center of the annular base plate 33, the support portion 34 and the annular base plate 33 are welded and fixed by a plurality of connecting ribs 35, and a protective net 36 is filled between adjacent connecting ribs 35. The provision of the protective net 36 not only allows the impurities 29 to leak smoothly into the collecting plate 32 through the net body 30 and the protective net 36, but also reduces the upward impact of the impurities 29 in the collecting plate 32 to a certain extent when the blower 12 blows air into the mixing bin 7, and avoids the problem that the impurities 29 dropped by stirring re-enter the mixing bin 7 and affect the fiber quality.
