Description

Technical Field

[0001] This invention belongs to the field of dust removal technology for drawing frames, specifically, it relates to a novel dust removal system for drawing frames. Background Technology

[0002] A dust removal system for a drawing frame is a device used to remove dust, short fibers, and impurities generated during the drawing frame's production process. When the drawing frame performs operations such as combining and drawing slivers and wool slivers, a large amount of fiber dust and other impurities are produced. The dust removal system can effectively collect and treat these impurities, improving the production environment and product quality. When the equipment is working, the fan is powered on, driving the blades to rotate and generating suction. Dust and fly ash from the drawing frame's working area are drawn into the housing through the suction pipe, and then filtered through a filter screen, leaving the dust and fly ash on the screen. Some advanced dust removal systems also use scrapers to scrape off the accumulated dust and fly ash from the filter screen, leaving it on the bottom plate of the housing.

[0003] However, existing dust collection systems for drawing frames require regular cleaning, maintenance, or replacement of the internal filters, which is cumbersome and necessitates stopping the machine and having a worker manually scrape and remove accumulated debris. This process is not only labor-intensive but also poses certain risks. Dust, shavings, and other debris not promptly removed may re-accumulate on the filters via airflow, affecting their normal operation. Equipment with scraping systems typically only moves a scraper back and forth across the filter surface, causing dust and shavings to accumulate on the sides, making cleaning difficult. Furthermore, the back-and-forth friction can force dust and shavings into the filter or even pass through it, affecting filtration efficiency. Therefore, a new type of dust collection system is urgently needed. Summary of the Invention

[0004] To address the technical problems of existing dust removal systems for drawing frames, which require regular cleaning, maintenance, or replacement of internal filters—a cumbersome process that necessitates stopping the machine and having a worker manually scrape and remove accumulated material—the basic concept of this invention is as follows: A novel dust removal system for a drawing frame includes a housing, a negative pressure dust removal pipe in the storage compartment, and a filter screen.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0015] like Figures 1 to 9 As shown, a novel dust removal system for a drawing frame includes a housing 1, a negative pressure dust removal pipe 5 in the storage compartment, and a filter screen 11. The housing 1 is equipped with a scraping mechanism, which includes a sliding plate 10 and a scraper 12. The sliding plate 10 has a sliding groove 19 on its side. A motor frame 20 is slidably sleeved inside the sliding groove 19. A second motor 9 is fixedly sleeved inside the motor frame 20. The drive shaft of the second motor 9 passes through the sliding groove 19, and a gear 21 is fixedly sleeved on its shaft. A friction wheel 22 is fixedly connected to the end of the drive shaft of the second motor 9. A friction plate 23 is fixedly installed on the inner side of the friction wheel 22. A rack 28 is fixedly connected to the inner side of the sliding plate 10. The rack 28 corresponds to and meshes with the gear 21. The sliding plate 10 is fixed on both sides of the edge of the filter screen 11. Several bristles 16 are fixedly connected to the inner side of the scraper 12, and the two ends of the scraper 12 are fixedly connected to the lower end of the friction wheel 22 through connecting blocks. A support rod 18 is fixedly connected to the upper end of the friction wheel 22, and a roller 17 is movably installed on the upper end of the support rod 18. In this setup, at regular intervals, the second motor 9 is activated, driving the friction wheel 22 to rotate and move downwards towards the filter screen via the meshing relationship of gear 21 and rack 28. The friction plate 23 increases friction. When the friction wheel 22 rubs against the edge of the filter screen 11, it rotates and pushes the scraper 12 against the surface of the filter screen 11. At the same time, the friction increases the adhesion between the scraper 12 and the filter screen. Similarly, when the second motor 9 drives the friction wheel 22 upwards, the scraper 12 lifts up and disengages from the filter screen 11. Simultaneously, it switches to rolling between the roller 17 and the edge of the filter screen 11, reducing friction. This cycle repeats, effectively pushing the dust on the surface of the filter screen 11 in one direction.

[0016] like Figures 1 to 9As shown, in a specific embodiment, a dust removal mechanism is provided on the inner bottom of the housing. The dust removal mechanism includes a suction hopper 3 and a baffle 14. The upper sides of the baffle 14 are movably connected to the inner side of the housing 1 via hinges. A ventilation opening is provided at the corresponding position of the housing 1 and the baffle 14. This ventilation opening corresponds to the size of the baffle 14, and the outer side of this ventilation opening is fixedly connected to the opening of the suction hopper 3. A rotating rod 27 is fixedly connected to one side of the upper end of the baffle 14, and the end of the rotating rod 27 is movably connected to... The telescopic rod 26 has a pry bar 25 fixedly connected to its other end. A fixed frame 24 is movably connected to the connection between the pry bar 25 and the telescopic rod 26. The other end of the fixed frame 24 is fixedly connected to the edge of the filter screen 11, and the end of the pry bar 25 corresponds to the lower end of the scraper 12 and is subjected to pressure by it. In a specific embodiment, a dust removal pipe 4 is fixedly connected to one end of the outer side of the suction hopper 3. The other end of the dust removal pipe is fixedly connected to the pipe body of the negative pressure dust removal pipe 5 in the warehouse and communicates with its interior.

[0017] In this setup, the scraped dust and fly debris will concentrate at the bottom of the housing 1. At the same time, when the scraper 12 moves down to the bottom of the filter screen 11, it will squeeze and rotate the pry bar 25. The baffle 14 will be opened by the telescopic rod 26 and the rotating rod 27, and the dust and fly debris at the bottom of the housing 1 will be sucked into the negative pressure dust removal pipe 5 of the warehouse through the suction hopper 3 and the dust removal pipe.

[0018] like Figures 1 to 9 As shown, in a specific embodiment, an air suction pipe 6 is fixedly installed at the upper end of the inside of the box 1. One end of the air suction pipe 6 passes through the back panel of the box 1, and the outlet of the other end of the air suction pipe 6 is located at the upper end of the filter screen 11. A ventilation mechanism is provided inside the box 1. The ventilation mechanism includes a ventilation box 29 and a first motor 8. A fixing plate 15 is fixedly connected to the periphery of the first motor 8. One end of the outer side of the fixing plate 15 is fixedly connected to the inner wall of the ventilation box 29.

[0019] In this setup, when the device is working, the first motor 8 starts, which drives the airflow through the fan blades 13, and then filters the dust and flying particles in the air through the filter screen 11.

[0020] like Figures 1 to 9 As shown, in a specific embodiment, a fan blade 13 is fixedly installed on the drive shaft of the first motor 8, the inner end opening of the ventilation box 29 is fixedly connected to the edge of the filter screen 11, the outer end of the ventilation box 29 penetrates the back plate of the box body 1 and is fixedly connected thereto, and an air outlet grille 7 is fixedly installed at the outer end opening of the ventilation box 29.

[0021] In this design, the invention uses a unidirectional scraping mechanism to push dust and fly ash in one direction, solving the problem of non-concentrated accumulation. This also prevents dust from being rubbed back and forth on the filter screen 11 and being crushed into the filter screen's interior. Furthermore, the device incorporates a dust removal system at the bottom of the housing 1, which uses negative pressure to suck up the scraped dust and fly ash. This equipment has a simple structure, is easy to maintain, reduces labor waste, improves production efficiency, and ensures timely discharge of dust, fly ash, and other debris, guaranteeing the normal operation of the filter screen 11. It also reduces the impact of dust, fly ash, and other debris on the product during operation, improving product quality.

[0022] The implementation principle of a novel dust removal system for a drawing frame in this embodiment is as follows: This invention solves the problem of dust and fly ash accumulation by using a unidirectional scraping mechanism to push dust and fly ash in one direction. It also prevents dust from being ground into the filter screen 11 due to repeated friction. Furthermore, the device incorporates a dust removal system at the bottom of the housing 1, which uses negative pressure to suck up the scraped dust and fly ash. This equipment has a simple structure, is easy to maintain, reduces labor waste, improves production efficiency, and ensures timely removal of dust, fly ash, and other debris, guaranteeing the normal operation of the filter screen 11. It also reduces the impact of dust, fly ash, and other debris on the product during operation, improving product quality. When this device is in operation, the first motor 8 starts, driving airflow through the fan blades 13. The air then passes through the filter screen 11 to filter dust and debris. At regular intervals, the second motor 9 starts, driving the friction wheel 22 to rotate and move it downwards from the filter screen via the meshing of gears 21 and rack 28. The friction plates 23 increase friction. When the friction wheel 22 rubs against the edge of the filter screen 11, it rotates, pushing the scraper 12 against the surface of the filter screen 11. Simultaneously, the friction increases the adhesion between the scraper 12 and the filter screen. Similarly, when the second motor 9 drives the friction wheel... When the wheel 22 moves upward, the scraper 12 lifts up and disengages from the filter screen 11. At the same time, it transforms into a roller 17 that rolls between the edge of the filter screen 11, reducing friction. This cycle repeats, pushing the dust on the surface of the filter screen 11 in one direction. The scraped dust and lint will concentrate at the bottom of the housing 1. Meanwhile, when the scraper 12 moves down to the bottom of the filter screen 11, it will squeeze and rotate the pry bar 25. The telescopic rod 26 and the rotating rod 27 pry open the baffle 14, drawing the dust and lint from the bottom of the housing 1 into the negative pressure dust removal pipe 5 of the warehouse through the suction hopper 3 and the dust removal pipe.
