Description

Technical Field

[0001] This invention belongs to the field of dust separation, specifically relating to a dust removal mechanism in a feeding system for ramie textile processing. Background Technology

[0002] Ramie textiles are natural fabrics woven from the bark fibers of ramie stems. They are moisture-wicking, breathable, antibacterial, mildew-resistant, firm, and smooth, and are commonly used in summer clothing, bedding, and handkerchiefs. They become softer with each wash, but wrinkle easily and require ironing. They are environmentally friendly, durable, and high-end linen textiles. However, the feeding of ramie generates a large amount of fiber dust and impurities, which not only endangers workers' health and poses a risk of fire and explosion, but also affects the workshop environment and product quality. Dust removal systems typically consist of filter boxes or multi-stage dust filters and fans, using negative pressure to suck away dust-laden air and separating dust and impurities through multi-stage filtration.

[0003] Patent CN217247463U discloses a dust removal mechanism for a short flax feeding system, including a dust removal pipe connected to a dust collection box. The dust collection box has a dust hopper at its bottom, a filter screen at its top, a filter bag above the filter screen, a clean air chamber above the filter bag, and an exhaust fan and an air outlet at its top. A material drop plate is fixedly connected below the filter screen, and the material drop plate has several openings. A first baffle and a second baffle are installed at each opening. One end of the first baffle is movably connected to the material drop plate, and one end of the second baffle is also movably connected to the material drop plate. The other ends of the first and second baffles are connected by springs. By providing the material drop plate, waste short flax and wool materials sucked into the dust collection box can fall directly into the dust hopper, avoiding direct contact with the filter screen and preventing blockage.

[0004] The above-mentioned devices also have the following problems: dust and fiber separation is incomplete, relying mainly on a fixed single screening structure, which is prone to clogging and has low separation efficiency. They lack negative pressure adsorption and zoned recovery design, which leads to impurities mixing into the raw materials, affecting the quality of subsequent processing. At the same time, internal cleaning and fiber recovery are inconvenient, maintenance is complicated, and it is difficult to achieve continuous and efficient purification. Summary of the Invention

[0012] According to another advantageous design of the invention, a torsion spring is provided at the hinge joint of the rotating shaft and the partition, the scraper brush and the circumferential surface of the screen cylinder abut against each other, the rear side of the gear and the front side of the partition abut against each other, the reciprocating screw and the drive shaft are connected by a synchronous belt drive, the toothed plate and the inner surface of the limiting guide rail are slidably connected, and the rear end of the connecting seat and the inner surface of the feeding box are hinged.

[0015] According to another advantageous design of the present invention, the front side of the top end of the L-shaped connecting rod is fixedly connected to the rear side of the toothed plate, the L-shaped connecting rod is slidably connected to the inner surface of the slide groove, the front side of the L-shaped connecting rod abuts against the rear side of the partition plate, the rear side of the L-shaped connecting rod abuts against the front side of the guide screen plate, a spring is provided between the bottom end of the guide rod and the inner surface of the push plate, the brush plate abuts against the lower surface of the guide screen plate, and the guide rod is slidably connected to the inner surface of the inclined guide plate.

[0016] The beneficial effects of this invention are: 1. Raw materials are fed into the feeding box and screened by the guide screen plate. Dust and fibers fall below. When the screen cylinder rotates, the raw materials fall quickly from the feed port through the inside of the screen cylinder onto the guide screen plate. The fan blows the fibers and dust forward out of the screen cylinder. The raw materials are blocked by the filter screen, achieving initial separation. The fibers and dust enter the front side of the partition and fall into the dust collector. The dust below the guide screen plate is also blown into the dust collector by the fan. At this time, the dust collector rotates and generates negative pressure, sucking in the dust and intercepting the fibers, achieving complete separation. After the fan is turned off, the fibers fall back to the bottom of the feeding box. The fan in the dust collector blows the dust to the left out of the ash discharge port, completing the screening and cleaning.

[0017] 2. When the screening cylinder rotates, its bottom circumferential surface contacts and rubs against the scraper brush. The scraper brush brushes off the fibers and dust that adhere to it, preventing them from being mixed back into the raw materials, preventing accumulation, and improving the separation effect during long-term feeding. Twisting the shaft can drive the connecting seat and scraper brush to rotate, increasing the contact friction and improving the cleaning effect. When the toothed plate moves back and forth and meshes with the gear, it drives the gear to rotate. When it moves away from the rear gear and the connecting shaft, it is elastically reset by the torsion spring, causing the connecting shaft and the connecting seat to twist back and forth, thereby making the scraper brush automatically scrape the surface of the screening cylinder, achieving automatic cleaning and improving the convenience of use.

[0018] 3. After the ramie raw material is fed in and the dust is removed, the cover can be opened to recycle the fibers at the bottom of the feeding box, reducing raw material waste. The push plate can gather the fibers on the right side of the cover for easy collection and improve recycling convenience. The L-shaped connecting rod drives the push plate to automatically push the fibers, accelerating fiber gathering and improving recycling efficiency. The push plate drives the brush plate to slide back and forth on the lower surface of the guide screen plate through the guide rod, sweeping off the fibers stuck in the screen holes, improving the collection and separation effect. The brush plate is guided by the guide screen plate and moves up and down automatically. The guide rod slides in the push plate and cooperates with the spring force to keep the brush plate always in contact with the guide screen plate, improving applicability. The falling fibers slide down to the left side of the push plate through the inclined guide plate, avoiding falling to the right side and causing recycling inconvenience. Attached Figure Description

[0021] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figure 1-8As shown, one embodiment of the present invention is a dust removal mechanism in a feeding system for ramie textile processing, comprising: a feeding box 1, a guide screen plate 2 snapped into the inside of the feeding box 1, a dust collector 5 rotatably connected to the inner wall of the feeding box 1, a drive shaft 6 fixedly connected to the right side of the dust collector 5, a main shaft 10 rotatably connected to the front inner surface of the feeding box 1, a bracket 11 fixedly connected to the circumferential surface of the main shaft 10, a screen cylinder 12 fixedly connected to the end of the bracket 11 away from the main shaft 10, a feed inlet 13 opened on the circumferential surface of the screen cylinder 12, and a filter screen 15 fixedly connected to the front side of the inner surface of the screen cylinder 12. Raw materials are fed into the feeding box 12. In the feeding bin 1, the material is screened by the guide screen plate 2, with dust and fibers falling below. When the screen cylinder 12 rotates, the raw material falls rapidly from the inlet 13 through the inside of the screen cylinder 12 onto the guide screen plate 2. The blower 14 blows the fibers and dust forward out of the screen cylinder 12. The raw material is blocked by the filter screen 15, achieving preliminary separation. The ramie cleaning device 8 is installed inside the feeding bin 1 to clean the residual material adhering to the device. The ramie recycling device 9 is installed at the bottom of the feeding bin 1 to recover the residual material after separation. The feeding bin 1 includes a partition plate 3, which is fixedly connected to the inner surface of the feeding bin 1. An observation port 4 is opened at the feeding bin. The front side of the feeding box 1 also includes a ash discharge port 7, which is fixedly connected to the left side of the feeding box 1. A blower 14 is fixedly connected to the rear side of the feeding box 1. A support plate 16 is fixedly connected to the inner surface of the feeding box 1. A baffle 17 is fixedly connected to the inner surface of the feeding box 1. Fibers and dust enter the front side of the partition 3 and fall into the dust collector 5. Dust below the guide screen plate 2 is also blown into the dust collector 5 by the blower 14. At this time, the dust collector 5 rotates to generate negative pressure, sucking in dust and intercepting fibers, achieving complete separation. The drive shaft 6 is rotatably connected to the inner surface of the right side of the feeding box 1, and the screen cylinder 12 is rotatably connected to the inner surface of the rear side of the feeding box 1. The inner surface of the filter screen 12 and the partition 3 are rotatably connected. The filter screen 15 and the support 11 are fixedly connected. A transparent plate is fixedly connected to the inner surface of the observation port 4. Multiple main shafts 10 are set on the top of the feeding box 1, and the multiple main shafts 10 are connected by synchronous belt drive. The support plate 16 and the circumferential surface of the screen cylinder 12 abut against each other. The front end of the support plate 16 and the rear side of the partition 3 are fixedly connected. The front end of the baffle 17 and the rear side of the partition 3 are fixedly connected. The left side of the baffle 17 and the right end of the guide screen plate 2 are hinged. After the fan 14 is turned off, the fiber falls back to the bottom of the feeding box 1. The fan in the dust collector 5 blows the dust to the left out of the ash discharge port 7, completing the screening and cleaning.

[0023] Working principle: The clumps of ramie raw material are poured into the feeding box 1. The raw material falls onto the guide screen plate 2 and rolls to the left along the inclined surface of the guide screen plate 2, thus being fed into the processing device. Because the guide screen plate 2 has sieve holes, dust and fibers that enter the feeding box 1 along with the ramie raw material fall below the guide screen plate 2, thereby separating the raw material suitable for processing from the fibers and dust impurities, improving the quality of subsequent processing. During the feeding process, when the raw material falls onto the support plate 16, the main shaft 10 is started. The main shaft 10 drives the bracket 11 to rotate, and the bracket 11 then drives... As the screening cylinder 12 rotates, friction occurs between its circumference and the raw material, loosening the accumulated material. The material then enters the screening cylinder 12 through the feed inlet 13 and, as the cylinder rotates, falls from the lower feed inlet 13 onto the guide screen plate 2. During this process, the blower 14 is activated, blowing a large amount of fiber and dust forward out of the screening cylinder 12. The raw material, blocked by the filter screen 15, remains inside the screening cylinder 12 and falls onto the guide screen plate 2 as the cylinder rotates. This process results in a large amount of material being removed from the screen. Fibers and dust are quickly separated from the raw materials, further improving the quality of the raw materials. After being blown out from the filter screen 15, the fibers and dust enter the front side of the baffle 3 and then fall downwards into the dust collector 5. The fibers and dust falling below the guide screen plate 2 are blown forward by the fan 14 due to the screen holes on the guide screen plate 2 and are drawn into the dust collector 5. At this time, the drive shaft 6 is activated, which drives the dust collector 5 to rotate and generate negative pressure, thereby sucking the dust into its interior, while the ramie fibers are intercepted on its surface, so that the dust is completely separated from the material. When closed... After the fan 14 slows down the speed of the dust collector 5, the fibers can fall back to the bottom of the feeding box 1. Then, the fan set on the right side of the dust collector 5 is started. The fan blows the dust inside the dust collector 5 to the left out of the ash discharge port 7, thus completing the dust discharge and quickly completing the screening of raw materials and cleaning of the feeding box 1. Since the right end of the guide screen plate 2 is hinged to the baffle 17, after the dust is discharged, the guide screen plate 2 is lifted to facilitate the recovery of the fibers at the bottom of the feeding box 1. The working condition inside the feeding box 1 can be observed in real time through the observation port 4.

[0024] like Figure 1-8As shown, based on the above embodiment, the ramie cleaning device 8 includes a rotating shaft 81, which is hinged to the inner surface of the partition plate 3. A connecting seat 82 is fixedly connected to the rear end of the rotating shaft 81. A scraper brush 83 is fixedly connected to the side of the connecting seat 82 near the screen cylinder 12. When the screen cylinder 12 rotates, its bottom circumferential surface contacts and rubs against the scraper brush 83. The scraper brush 83 brushes off the adhered fibers and dust, preventing them from being mixed back into the raw materials, preventing accumulation, and improving the separation effect during long-term feeding. The ramie cleaning device 8 also includes a gear 84, which is fixedly connected to the circumferential surface of the rotating shaft 81. A reciprocating screw 85 is rotatably connected to the inner surface of the feeding box 1. A sleeve shaft 86 is threadedly connected to the circumferential surface of the reciprocating screw 85. A connecting shaft 87 is fixedly connected to the circumferential surface of the sleeve shaft 86. A toothed plate 88 and a limiting guide rail are fixedly connected to the rear end of the connecting shaft 87. 89 is fixedly connected to the front side of the partition 3. Twisting the rotating shaft 81 can drive the connecting seat 82 and the scraper brush 83 to rotate, increasing the contact friction and improving the cleaning effect. A torsion spring is provided at the hinge of the rotating shaft 81 and the partition 3. The scraper brush 83 abuts against the circumferential surface of the screen cylinder 12. The rear side of the gear 84 abuts against the front side of the partition 3. The reciprocating screw 85 and the drive shaft 6 are connected by synchronous belt transmission. The toothed plate 88 and the inner surface of the limit guide rail 89 are slidably connected. The rear end of the connecting seat 82 is hinged to the inner surface of the feeding box 1. When the toothed plate 88 moves back and forth and meshes with the gear 84, it drives the gear 84 to rotate. When it moves away, the gear 84 and the connecting shaft 87 are elastically reset by the torsion spring, causing the connecting shaft 87 and the connecting seat 82 to reciprocate and twist, thereby making the scraper brush 83 automatically scrape the surface of the screen cylinder 12, realizing automatic cleaning and improving the ease of use.

[0025] Working principle: During the rotation of the screening cylinder 12, its bottom circumferential surface contacts and rubs against the scraper brush 83. The scraper brush 83 uses friction to brush off the fibers and dust adhering to the circumferential surface of the screening cylinder 12, thus preventing fibers and dust from being re-mixed into the raw materials entering the feeding box 1, causing fibers and dust to accumulate. This promotes the separation of fibers and dust during long-term feeding. Furthermore, twisting the rotating shaft 81 causes the connecting seat 82 to rotate at a certain angle, which in turn causes the scraper brush 83 to rotate at a certain angle. This relative movement between the scraper brush 83 and the screening cylinder 12 enhances the removal of fibers and dust from the surface of the screening cylinder 12. The dust removal effect is achieved by the synchronous drive of the reciprocating screw 85 when the drive shaft 6 rotates. The reciprocating screw 85 drives the sleeve shaft 86 to move back and forth, and the sleeve shaft 86 drives the connecting shaft 87 to move back and forth. The connecting shaft 87 then drives the toothed plate 88 to slide back and forth within the limit guide rail 89. When the toothed plate 88 meshes with the gear 84, it rotates at a certain angle. When the toothed plate 88 moves away from the gear 84, the gear 84 and the connecting shaft 87 are rotated and reset by the elastic reset effect of the torsion spring. This causes the connecting shaft 87 and the connecting seat 82 to twist back and forth. The connecting seat 82 then drives the scraper brush 83 to twist back and forth, so that the scraper brush 83 automatically scrapes the surface of the screen cylinder 12, improving the ease of use of the device.

[0026] like Figure 1-8As shown, based on the above embodiment, the ramie recycling device 9 includes a cover plate 91, which is hinged to the inner surface of the left side of the feeding box 1. A push plate 92 is slidably connected to the inner surface of the feeding box 1. An L-shaped connecting rod 93 is fixedly connected to the front side of the upper surface of the push plate 92. After the ramie raw material is fed in and the dust is discharged, the cover plate 91 can be opened to recycle the fibers at the bottom of the feeding box 1, reducing raw material waste. The push plate 92 can gather the fibers on the right side of the cover plate 91 for easy collection and improved recycling convenience. The ramie recycling device 9 also includes a chute 94, which is opened inside the partition 3. A guide rod 96 is slidably connected to the inner surface of the push plate 92. A brush plate 95 is fixedly connected to the top of the guide rod 96. An inclined guide plate 97 is fixedly connected to the upper surface of the push plate 92. The L-shaped connecting rod 93 drives the push plate 92 to automatically push the fibers, accelerating fiber aggregation and improving recycling efficiency. The push plate 92 is connected to the guide rod 93. The brush plate 95 slides back and forth on the lower surface of the guide screen plate 2, sweeping away fibers stuck in the screen holes, improving the collection and separation effect. The front side of the top of the L-shaped connecting rod 93 is fixedly connected to the rear side of the toothed plate 88. The L-shaped connecting rod 93 is slidably connected to the inner surface of the slide groove 94. The front side of the L-shaped connecting rod 93 abuts against the rear side of the partition plate 3. The rear side of the L-shaped connecting rod 93 abuts against the front side of the guide screen plate 2. A spring is provided between the bottom end of the guide rod 96 and the inner surface of the push plate 92. The brush plate 95 abuts against the lower surface of the guide screen plate 2. The guide rod 96 is slidably connected to the inner surface of the inclined guide plate 97. The brush plate 95 is guided by the guide screen plate 2 and moves up and down automatically. The guide rod 96 slides in the push plate 92 and cooperates with the spring force to keep the brush plate 95 always in contact with the guide screen plate 2, improving applicability. The falling fibers slide down to the left side of the push plate 92 through the inclined guide plate 97, avoiding falling to the right side and causing inconvenience in recycling.

[0027] Working principle: After all the ramie raw materials are fed into the processing device and all the dust is discharged from the feeding box 1, the cover plate 91 is opened. At this time, the fibers that have fallen to the bottom of the feeding box 1 can be recovered from inside the feeding box 1, thereby reducing the waste of raw materials. Pushing the push plate 92 from right to left, the push plate 92 can push the fibers at the bottom of the feeding box 1 to the left and gather them on the right side of the cover plate 91, making it convenient for workers to collect and improving the ease of use of the device. As the toothed plate 88 slides back and forth in the limiting guide rail 89, it drives the L-shaped connecting rod 93 to slide back and forth in the slide groove 94. The L-shaped connecting rod 93 then drives the push plate 92 to automatically push the fibers, thereby quickly gathering the fibers and improving the raw material recovery efficiency. During the movement of the push plate 92, the guide rod 96 drives the brush plate 95 to slide back and forth on the lower surface of the guide screen plate 2. During its movement, the brush plate 95 sweeps away fibers stuck in the screen holes of the guide screen plate 2, thus preventing fibers from getting stuck on the guide screen plate 2 and further improving the collection and raw material separation effects. As the brush plate 95 moves back and forth, it is guided by the guide screen plate 2 and moves up and down automatically. When the brush plate 95 moves up and down, it slides up and down in the push plate 92 through the guide rod 96 and squeezes or moves away from the spring set between the bottom end of the guide rod 96 and the inner surface of the push plate 92. The elastic force of the spring can push the guide rod 96 and the brush plate 95 upward, so that the brush plate 95 can always be in contact with the guide screen plate 2, improving the applicability of the device. The falling fibers fall onto the inclined guide plate 97 and slide down the inclined surface of the inclined guide plate 97 to the left side of the push plate 92, avoiding the fibers falling to the right side of the push plate 92 and causing inconvenience in recycling.
