Description

Technical Field

[0001] The invention belongs to the technical field of fabric blending, and particularly relates to a graphene wool fabric blending device. Background Art

[0002] As a new two-dimensional material, graphene possesses excellent mechanical, electrical, thermal, and optical properties, and therefore holds broad application prospects in many fields. Wool, a traditional natural fiber, offers excellent warmth and comfort, but its mechanical and electrical properties are relatively poor. To combine the advantages of graphene and wool, researchers have proposed the concept of a graphene-wool blended fabric.

[0003] There are two main processes for multi-fiber blending: disk blending and sliver blending. Disk blending involves placing two or more fibers in bales according to a weight ratio. Sometimes, due to significant differences in fiber properties, varying sizes and tightness of the raw material packages, the disc beater may grab more or less material, resulting in uneven fiber blending and unstable blending ratios. Sliver blending involves separately processing two or more fibers into sliver through blowroom and carding, then blending them in proportion during the drawing process. This increases the number of blowroom and carding steps and management complexity, making uniform blending difficult. This necessitates increasing the number of draw lines, necessitating a three-line drawing process.

[0004] In response to the above problems, the present invention provides a graphene wool fabric blending device, which aims to solve the technical defects of disc blending and strip blending, achieve effective mixing of graphene and wool, and improve blending efficiency. Summary of the Invention

Graphene fibers and wool fibers are fed into the first feed port and the second feed port respectively, the driving assembly drives the No. 1 ring and the No. 2 ring to rotate, the No. 1 ring and the No. 2 ring drive the scraper rod to rotate around the rotating shaft, the scraper rod rotates the graphene fibers / wool fibers at the first feed port / the second feed port to the discharge port, the graphene fibers and the wool fibers are squeezed between the No. 1 ring and the No. 2 ring and then discharged from the shell through the discharge port.

[0016] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1 like Figure 1-5 As shown, a graphene wool fabric blending device includes two parallel, opposing support plates 7 fixed to the ground. A housing 4 having a first feed port 1, a second feed port 2, and a discharge port 3 is fixed between the two support plates 7. The first feed port 1, the second feed port 2, and the discharge port 3 are interconnected. The first feed port 1 and the second feed port 2 are located above the housing 4, and the discharge port 3 is located below the housing 4. A conveyor can be used to transport graphene fibers and wool fibers into the first feed port 1 and the second feed port 2.

[0018] A first ring 5 and a second ring 6 are rotatably mounted through the housing 4. Their axes are parallel and horizontal. A disc 29 is rotatably mounted on each end of the first and second rings 5 and 6. The disc 29 is fixedly mounted on a support plate 7.

[0019] The No. 1 ring 5 and the No. 2 ring 6 are each connected to a drive assembly, which includes two reducers 11 fixed on two support plates 7. The input ends of the two reducers 11 are provided with drive motors 12, and a synchronous belt 13 is provided between the output end of the reducer 11 and the No. 1 ring 5 / No. 2 ring 6. The drive motor 12 drives the synchronous belt 13 to rotate through the reducer 11, thereby realizing the respective rotation of the No. 1 ring 5 and the No. 2 ring 6.

[0020] A rotating shaft 8 is rotatably mounted in each of the No. 1 and No. 2 rings 5 and 6 at a non-axial position. The rotating shaft 8 is rotatably mounted on a disk 29. A plurality of scraper rods 9 are fixedly mounted on the rotating shaft 8. A plurality of limiting holes 10 corresponding to the scraper rods 9 are provided on the No. 1 and No. 2 rings 6. The scraper rods 9 are inserted into the limiting holes 10. The scraper rods 9 can be arranged into a plurality of scraper rod groups arranged along the circumference of the rotating shaft 8. Each group includes a plurality of scraper rods 9 in a straight line. The scraper rods 9 are arranged parallel to each other, so that the scraper rods 9 are radially distributed on the surface of the rotating shaft 8. The scraper rods 9 form a structure similar to comb teeth, which can smoothly comb the fibers so that the fibers move with the scraper rods 9. If a scraper is used instead of a scraper rod, the scraper cannot form a good grip on the fibers during rotation due to the smooth edge of the scraper. As a result, the amount of fibers captured by the scraper is not stable enough.

[0021] When the first and second rings 5 and 6 rotate, they drive the scraper 9, causing the rotating shaft 8 to rotate synchronously. Because the center of rotation of the scraper 9 is different from that of the first and second rings 5 and 6, the scraper 9 rotates in a cycle of entering the first and second rings 5 and 6, exiting, and then entering the first and second rings 5 and 6 again. When the scraper 9 enters the deepest position of the first and second rings 5 and 6, the end of the scraper 9 is flush with the outer ring of the first and second rings 5 and 6, preventing the scraper 9 from being unable to extend. Furthermore, the arrangement of the scraper 9 entering the first and second rings 5 and 6 prevents the scraper 9 from colliding with the first and second rings 5 and 6, maintaining a narrow distance between the first and second rings 5 and 6, thereby compacting the graphene fibers and wool fibers. In addition, when the scraper rod 9 enters the No. 1 ring 5 / No. 2 ring 6, the No. 1 ring 5 / No. 2 ring 6 can be used to scrape the surface of the scraper rod 9, which can successfully separate the scraper rod 9 from the fiber and prevent the fiber from adhering, thereby reducing the chance of fiber clogging at the discharge port 3 and ensuring that the fibers are mixed according to the ratio.

[0022] During mixing, graphene fibers and wool fibers are fed into the mixing apparatus through the first and second feed ports 1 and 2, respectively. The feeding amount of the graphene fibers and wool fibers can be controlled by controlling the width of the first and second feed ports 1 and 2. The scraping amount of fibers can also be controlled by controlling the diameters of the first and second rings 5 and 6 and adjusting the length of the scraper rod 9.

[0023] When the first and second feed ports 1 and 2 are filled with fibers, the drive assembly rotates the first and second rings 5 and 6, which in turn drive the scraper rods 9 around the rotation axis 8. During rotation, the scraper rods 9 contact the fibers at the bottom of the first and second feed ports 1 and 2. As they rotate upward, they penetrate the accumulated fibers. As they continue to rotate, they scrape a portion of the accumulated fibers, carrying this portion of fibers with them as they rotate within the housing 4. When the scraper rods 9 on the first and second rings 5 and 6 reach the center of the two rings, they press the scraped fibers together and drive them downward until they exit the discharge port 3. The squeezing action of the first and second rings 5 and 6 compresses the graphene fibers and wool fibers, forming two composite layers. The two composite layers have different thicknesses, but are bonded together according to the designed blending ratio. Subsequent processing produces a uniform yarn, which is then woven into a graphene-wool blended fabric.

[0024] Since a large amount of fibers are accumulated at the first feed port 1 and the second feed port 2, the fibers at the bottom are squeezed into a dense state under the action of gravity, and the amount of fibers scraped by the scraping rod 9 each time is basically the same.

[0025] Furthermore, a channel 14 is fixed between the two support plates 7, and a through hole 15 is provided on the channel 14. A slider 16 is movably installed in the through hole 15. A plurality of extrusion parts 17 are provided at one end of the slider 16 facing the inner cavity of the channel 14, and the slider 16 is connected to a reciprocating moving component.

[0026] It should be noted that the graphene fibers and wool fibers are mixed in proportion and then enter the channel 14 from the discharge port 3. Since the mixed fibers are a two-layer composite structure, the combination is not firm and is prone to stratification during subsequent processing.

[0027] To this end, the wool fibers and graphene fibers are mixed together using the extruder 17 so that the two layers of fibers can be mixed more fully, the two fibers cross each other and are difficult to separate, and stratification is not likely to occur during subsequent operations.

[0028] The reciprocating assembly includes a drive shaft 18 rotatably mounted on the support plate 7. The drive shaft 18 and the secondary ring 6 share a synchronous belt 13, meaning the synchronous belt 13 on the secondary ring 6 simultaneously drives both the secondary ring 6 and the drive shaft 18. Control of the rotational speeds of the secondary ring 6 and the drive shaft 18 is achieved by controlling the diameters of the secondary ring 6 and the drive shaft 18. A rotating wheel 19 is concentrically fixedly mounted on the drive shaft 18. A connecting plate 20 is rotatably mounted on the rotating wheel 19 at a non-central position. The connecting plate 20 is hingedly connected to the slider 16.

[0029] The working principle of the reciprocating assembly is as follows: the synchronous belt 13 on the second ring 6 drives the transmission shaft 18 to rotate, so that the rotating wheel 19 rotates, and the rotating wheel 19 drives the connecting plate 20 to move. The connecting plate 20 drives the slider 16 to reciprocate in the through hole 15.

[0030] Because the mixed fibers are connected by multiple parts of fibers scraped from the scraper rod 9, they are discontinuous in their moving direction. For this reason, the channel 14 includes a vertical section 22, a transition section and a horizontal section 23. The through hole 15 is located above the horizontal section 23, and there is an angle between the through hole 15 and the horizontal section 23, so that when the slider 16 enters the through hole 15, it moves in the direction of fiber movement, which can make the upper wool fibers obliquely downward into the graphene fibers, so that the two can be mixed with each other in the vertical direction, and can also be interspersed with each other in the horizontal direction to form a continuous fiber sheet, and finally a fiber roll is made.

[0031] The extrusion element 17 has a pointed tip, which is provided with a plurality of grooves 21 extending parallel to the length of the slider 16. The grooves 21 have sharp corners. When the extrusion element 17 squeezes the wool fibers, the sharp corners create a hooking effect on the wool fibers, allowing the wool fibers in the upper layer to follow the tip into the layered structure formed by the graphene fibers in the lower layer. When the tip moves upward, the wool fibers are blocked by the graphene fibers and then retained.

[0032] The extrusion piece 17 is made of rubber material. When the extrusion piece 17 contacts the bottom of the channel 14, it is deformed and can insert the wool fibers toward both sides of the graphene fibers in the horizontal direction, further improving the mixing degree of the wool fibers and the graphene fibers.

[0033] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
