Description

Technical Field

[0001] The invention belongs to the technical field of dust removal for a drawing frame, and in particular relates to a novel dust removal system for a drawing frame. Background Art

[0002] The drawing frame dust removal system is a device used to remove dust, short fibers and impurities generated by the drawing frame during the production process. When the drawing frame combines and stretches fiber raw materials such as cotton strips and wool strips, a large amount of fiber dust and other impurities will be generated. The dust removal system can effectively collect and process these impurities, improve the production environment, and improve product quality. When the equipment is working, the fan is powered on to drive the blades to rotate and generate suction. The dust, flying fibers, etc. in the working area of ​​the drawing frame are sucked into the box through the suction pipe, and then the air is filtered through the filter, so that the dust and flying fibers remain on the filter. Some advanced dust removal systems will scrape off the dust and flying fibers accumulated on the filter through the scraper action, so that the dust and flying fibers remain on the bottom plate of the box.

[0003] However, the existing drawing frame dust removal system requires regular cleaning and maintenance of the internal filter or replacement of the filter, which is troublesome to operate, and the operator must stop the machine and use a scraper to manually scrape and remove the deposits. In this process, not only is labor wasted, but there is also a certain degree of danger. If the scraped dust, flying flowers and other debris are not cleaned in time, they may accumulate on the filter again through the airflow, affecting the normal operation of the filter; the equipment with a scraping system generally only moves the scraper back and forth on the surface of the filter, which will cause dust and flying flowers to accumulate on both sides, which is not concentrated enough and is more troublesome to clean. At the same time, the back and forth friction will crush the dust and flying flowers into the filter or directly pass through the filter, affecting the filtering effect. Therefore, a new dust removal system is urgently needed. Summary of the invention

[0014] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. 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 box body 1, a warehouse negative pressure dust removal pipe 5 and a filter screen 11. A scraping mechanism is arranged inside the box body 1, and the scraping mechanism includes a slide plate 10 and a scraper 12. A slide groove 19 is opened on the side of the plate body of the slide plate 10. A motor frame 20 is slidably sleeved inside the slide groove 19. A second motor 9 is fixedly sleeved inside the motor frame 20. The transmission shaft of the second motor 9 passes through the slide groove 19, and a gear 21 is fixedly sleeved on its shaft. A friction wheel 22 is fixedly connected to the end of the transmission shaft of the second motor 9, and 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 slide plate 10, and the rack 28 corresponds to the gear 21 and meshes with it, and the slide plate 10 is fixed on both sides of the edge of the filter screen 11. A plurality of bristles 16 are fixedly connected to the inner side of the scraper 12, and both ends of the scraper 12 are fixedly connected to the lower end of the friction wheel 22 through connecting blocks.

In this setting, the second motor 9 is started at regular intervals, and the friction wheel 22 is driven to rotate and move toward the bottom of the filter through the meshing relationship between the gear 21 and the rack 28, wherein the friction plate 23 increases the friction force. When the friction wheel 22 rubs against the edge of the filter 11, it rotates to push the scraper 12 toward the surface of the filter 11, and at the same time, the friction force will increase the fit between the scraper 12 and the filter. Similarly, when the second motor 9 drives the friction wheel 22 to move upward, the scraper 12 is lifted and separated from the filter 11, and at the same time, it is converted into rolling between the roller 17 and the edge of the filter 11, reducing the friction force, and repeating the cycle to achieve the effect of pushing the dust on the surface of the filter 11 in one direction.

[0016] like Figures 1 to 9As shown, in the specific embodiment, a dust removal mechanism is provided at the inner bottom of the box body, and the dust removal mechanism includes an air suction hopper 3 and a baffle 14.

The size of the vent corresponds to that of the baffle 14, and the outer side of the vent is fixedly connected to the opening of the air suction hopper 3; a rotating rod 27 is fixedly connected to one side of the position between the upper ends of the baffle 14, and the end of the rotating rod 27 is movably connected to A telescopic rod 26, the other end of which is fixedly connected to a pry bar 25, a fixing frame 24 is movably connected to the connection between the pry bar 25 and the telescopic rod 26, the other end of the fixing 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 squeezed and stressed therewith; in a specific embodiment, one end of the outer side of the suction hopper 3 is fixedly connected to a dust removal pipe 4, and the other end of the dust removal pipe is fixedly connected to the pipe body of the warehouse negative pressure dust removal pipe 5 and is connected to its interior.

[0017] In this arrangement, the scraped dust and flying flowers will be concentrated at the bottom of the box body 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, and pry the baffle 14 open through the telescopic rod 26 and the rotating rod 27, and the dust and flying flowers at the bottom of the box body 1 will be sucked into the warehouse negative pressure dust removal pipe 5 through the suction hopper 3 and the dust removal pipe.

[0018] like Figures 1 to 9 As shown, in a specific embodiment, a suction pipe 6 is fixedly installed at the upper end of the interior of the box body 1, one end of the suction pipe 6 passes through the back plate of the box body 1, and the other end of the suction pipe 6 is arranged at the upper end of the filter 11, and a ventilation mechanism is arranged inside the box body 1, the ventilation mechanism includes a ventilation box 29 and a first motor 8, and the periphery of the first motor 8 is fixedly connected to a fixing plate 15, and 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 configuration, when the device is working, the first motor 8 is started, the airflow is driven by the fan blades 13, and the dust and flying flowers in the air are filtered through the filter 11.

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

[0021] In this setting, the present invention pushes the dust and flying flowers in one direction through a one-way scraping mechanism, thereby solving the problem of uneven accumulation, and preventing the dust from rubbing back and forth on the filter 11 and being crushed into the filter. At the same time, the device sets a dust removal system at the bottom of the box 1 to suck the scraped dust and flying flowers through negative pressure; the device has a simple structure and is easy to maintain, reduces labor waste, improves production efficiency, and enables dust, flying flowers and other debris to be discharged in time to ensure the normal operation of the filter 11; at the same time, it reduces the impact of dust, flying flowers and other debris on the product during work, thereby improving product quality.

[0022] The implementation principle of a new dust removal system for a drawing frame in this embodiment is as follows: The present invention uses a one-way scraping mechanism to push dust and flying flowers in one direction, thereby solving the problem of uneven accumulation, and at the same time preventing dust from rubbing back and forth on the filter screen 11 and being crushed into the filter screen. At the same time, the device sets a dust removal system at the bottom of the box body 1 to suck the scraped dust and flying flowers through negative pressure. The device has a simple structure and is easy to maintain, which reduces labor waste, improves production efficiency, and enables dust, flying flowers and other debris to be discharged in time, thereby ensuring the normal operation of the filter screen 11. At the same time, it reduces the impact of dust, flying flowers and other debris on the product during work, thereby improving product quality. When the device is working, the first motor 8 is started, and the airflow is driven by the fan blades 13, and then the dust and flying flowers in the air are filtered through the filter 11, and the second motor 9 is started at a certain interval, and the friction wheel 22 is driven to rotate and move under the filter through the meshing relationship between the gear 21 and the rack 28, wherein the friction plate 23 has the effect of increasing the friction force. When the friction wheel 22 rubs against the edge of the filter 11, it will rotate to push the scraper 12 to the surface of the filter 11, and the friction force will increase the fit between the scraper 12 and the filter. Similarly, when the second motor 9 drives the friction plate 23 to rotate, the friction plate 23 will rotate and push the scraper 12 to the surface of the filter 11. When the wheel 22 moves upward, the scraper 12 is lifted and separated from the filter 11, and at the same time it is converted into rolling between the roller 17 and the edge of the filter 11, reducing friction, repeating the cycle, and having the effect of pushing the dust on the surface of the filter 11 in one direction; the scraped dust and flying flowers will be concentrated at the bottom of the box body 1. At the same time, when the scraper 12 moves down to the bottom of the filter 11, it will squeeze and rotate the pry bar 25, and pry the baffle 14 open through the telescopic rod 26 and the rotating rod 27, and the dust and flying flowers at the bottom of the box body 1 will be sucked into the warehouse negative pressure dust removal pipe 5 through the suction hopper 3 and the dust removal pipe.
