[0002] In the industrial production of dried noodles, a large amount of dust is generated in many key stages from raw material processing to finished product packaging. This dust mainly comes from the processes of flour conveying, mixing, rolling and forming, as well as the finishing of dried noodles after cutting and drying. In order to ensure the production environment and production safety, dust absorption equipment is needed to absorb and treat the scattered dust.

[0003] Prior art (Chinese patent publication number: CN120022672A, publication date: 2025-05-23) discloses a dust collection device for flour processing, belonging to the field of dust collection technology. It includes a base plate, an adjustment mechanism on the top of the base plate, a dust collection assembly on the top of the adjustment mechanism, and a cleaning mechanism inside the dust collection assembly. During use, turning on the switch of the electric push rod three causes a moving plate to move a brush. One end of the moving plate is arc-shaped to match the concave-convex plate, thus allowing the moving plate to move... At the same time, it can reciprocate with the concave and convex plates, allowing the mounting frame to shake left and right, thus facilitating the removal of dust adhering to the filter screen. Simultaneously, a brush is used to clean the dust, ensuring the filter screen's efficiency and improving dust collection efficiency. Meanwhile, the sleeve, under the action of a spring, can drive the mounting frame to spring back to its original position, facilitating the reciprocating shaking of the concave and convex plates. The structure is simple and easy to operate, automating the cleaning process. Existing technology (Chinese Patent No. CN219942168U, Publication Date: 2023-11-03) discloses an environmentally friendly dust removal mechanism for a flour processing plant, including a ring... The dust collector enclosure has a humidification pipe fixed to its top. A partition is installed between the dust collector enclosure and the humidification pipe. A dust interception structure is movably installed on the dust collector enclosure. The dust interception structure includes a filter, which consists of two interlocking housings. Each housing includes a conical panel with micropores distributed throughout. Inner and outer perimeter plates are respectively provided on the edges of the conical panel. Filter ring plates are provided on the inner perimeter plates inside the housings. A fan is installed on the windward side of the dust interception structure. A flow outlet is provided on the partition directly above the air outlet of the dust interception structure. The part is equipped with an antibacterial sponge block, and an exhaust cover is movably connected to the humidification pipe on the top of the antibacterial sponge block. It has the advantages of good interception and filtration effect and easy cleaning of dust accumulated in the filter. The prior art (publication number: CN219481940U, Chinese patent published on 2023-08-08) discloses a dust removal device for wheat flour processing, which relates to the field of dust removal equipment technology. It aims to solve the problem that most of the dust removal equipment used in wheat flour processing is a bag dust collector. When wheat flour is discharged, the flour easily adheres to the bag dust collector, resulting in poor performance. The bag filter dust collector has a discharge hopper at the bottom, and the discharge hopper and the bag filter dust collector are integrated into one structure. A vibrating device is installed below the discharge hopper, and the vibrating device is fixedly connected to the discharge hopper by fastening screws. A rotating shaft is installed inside the vibrating device, and the rotating shaft is rotatably connected to the vibrating device through bearings. A rotating head is installed on the outside of the rotating shaft, and the rotating head is fixedly connected to the rotating shaft by bolts. An impact head is installed at one end of the rotating head, and the impact head is rotatably connected to the rotating head. The impact head can contact the outer surface of the discharge hopper. A driven wheel is installed on the outside of the rotating shaft, and a motor is installed inside the vibrating device. While existing dust absorption equipment can clean the filter mechanism during use, the cleaning method is limited, which means that some dust stuck in the filter pores cannot be effectively removed. This can lead to clogging of the filter mechanism and affect the dust removal and filtration effect, thus exhibiting certain defects in use. Summary of the Invention

[0004] The purpose of this invention is to provide a dust absorption device for noodle production, in order to solve the problem mentioned in the background art that the current dust absorption devices for noodle production on the market have a single cleaning method, which makes it impossible to effectively remove some of the dust stuck in the filter holes, thus causing the filter mechanism to be blocked and affecting the dust removal and filtration effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust absorption device for noodle production, comprising an absorption cylinder fixedly installed above the processing area, a fan fixedly installed on the top of the absorption cylinder, the air inlet of the fan being connected to the upper end of the absorption cylinder, and a collection seat threadedly connected to the lower end of the absorption cylinder, while an air inlet assembly is provided on the outer side of the absorption cylinder, a fixing ring fixedly installed on the upper inner side of the absorption cylinder, and a first movable plate and a second movable plate sealed and slidingly installed on the upper inner side of the absorption cylinder, the first movable plate and the second movable plate being located on the upper and lower sides of the fixing ring respectively, a first spring fixedly connected between the fixing ring and the first movable plate, and a second spring fixedly connected between the first movable plate and the second movable plate, a pressure regulating assembly provided on the second movable plate, a fixing seat fixedly installed on the lower inner side of the absorption cylinder, and a filter assembly connected between the first movable plate and the fixing seat, and a tapping assembly for assisting in cleaning the filter assembly is also provided between the fixing ring and the first movable plate.

[0006] Preferably, the air intake assembly includes an air intake pipe that is uniformly and fixedly installed on the absorption cylinder, and a dust suction hood is fixedly connected to the lower end of the air intake pipe, and the dust suction hood is arranged in a ring structure.

[0007] Preferably, the pressure regulating component includes a through-hole structure on the second movable plate, and a sealing plug is sealed and fitted in the through-hole structure. A third spring is fixedly connected between the sealing plug and the second movable plate. When the fan is working, the second movable plate drives the first movable plate to move upward under the action of negative pressure. When the second movable plate cannot move upward, the sealing plug moves upward elastically, so that the through-hole structure can be ventilated.

[0008] Preferably, the filter assembly includes a connecting seat that is uniformly and fixedly installed through the first movable plate, and a mounting seat is threadedly connected to the lower part of the connecting seat, and a dust collector bag is fixedly connected to the lower part of the mounting seat.

[0009] Preferably, a rotating seat is evenly and elastically mounted on the fixed seat, and the rotating seat is fixedly connected to the lower end of the dust collector bag. The connecting seat, the dust collector bag and the rotating seat are coaxially arranged, and the dust collector bag is initially twisted.

[0010] Preferably, during the upward movement of the first movable plate, the dust collector bag is pulled to unfold and return to a cylindrical shape, and during the unfolding of the dust collector bag, the rotating seat on the outer side of its lower end is elastically rotated.

[0011] Preferably, an external toothed ring is fixedly installed on the outer side of the rotating seat, and an internal toothed ring is rotatably installed on the top of the fixed seat, with the external toothed ring and the internal toothed ring meshing and connected, and the upper surface of the internal toothed ring is inclined.

[0012] Preferably, a cleaning scraper is uniformly fixedly installed on the upper surface of the inner toothed ring, and the cleaning scraper is attached to the inner wall of the absorption cylinder. During the rotation of the inner toothed ring, the cleaning scraper is driven to scrape off the dust adhering to the inner wall of the absorption cylinder.

[0013] Preferably, the tapping assembly includes a guide post fixedly installed on the inner side of the upper end of the absorption cylinder, and a spiral guide groove is provided on the outer side of the guide post. A movable shaft is rotatably installed through the middle position of the second movable plate, and the movable shaft passes through the middle position of the first movable plate. The upper part of the guide post and the movable shaft form a lifting sleeve structure, and a ball is embedded in the upper inner wall of the movable shaft. The ball rolls along the guide groove. The second movable plate drives the movable shaft to lift and rotate at the same time.

[0014] Preferably, striking elements are uniformly fixedly installed on the outer side of the movable shaft, and when the movable shaft drives the striking elements to rotate, the striking elements intermittently tap the outer side of the dust collector bag.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the dust absorption equipment for noodle production can efficiently absorb and filter dust, and can achieve automatic unclogging in multiple ways after use, effectively ensuring continuous filtration effect, as detailed below; 1. The device is equipped with a first movable plate and a second movable plate. When the fan starts, the second movable plate can move upward under negative pressure. At the same time, the second movable plate will drive the first movable plate to move upward synchronously through the second spring, so that the first movable plate compresses the first spring. When the first movable plate cannot move upward, the sealing plug will move upward under air pressure, so that the air hole structure on the second movable plate can deliver air. When the fan stops working, the first movable plate will move downward and reset. At this time, it can push the airflow to backwash the dust collector bag, thereby preventing the dust collector bag from becoming blocked.

[0016] 2. The device is equipped with a first movable plate, a dust collector bag, and a rotating seat. As the first movable plate moves down and resets, the distance between the upper and lower ends of the dust collector bag is shortened. At the same time, the rotating seat will rotate and reset elastically, thereby twisting the dust collector bag and creating wrinkles on its surface. This loosens the dust filtered from the surface of the dust collector bag and further improves the cleaning effect of the dust collector bag.

[0017] Furthermore, it is also equipped with an outer toothed ring, an inner toothed ring, and a cleaning scraper. As the rotating seat rotates, it can drive the outer toothed ring to rotate, so that the outer toothed ring drives the inner toothed ring to rotate synchronously through meshing. This allows the cleaning scraper on the outside of the inner toothed ring to slide against the inner wall of the absorption cylinder, thereby achieving automatic cleaning of the inner wall of the absorption cylinder.

[0018] 3. Equipped with guide columns, a movable shaft, and striking components, the second movable plate moves downward, which in turn drives the movable shaft to move downward synchronously. This causes the balls on the upper inner wall of the movable shaft to roll along the guide groove on the outer side of the guide column, thereby driving the movable shaft to move downward and rotate simultaneously. This allows the striking components on the outer side of the movable shaft to intermittently tap different positions of the dust collector bag, thereby further improving the cleaning effect.

[0021] Example 1: Existing dust absorption equipment for noodle production uses a single cleaning method for its filtration mechanism, making it prone to clogging and reducing filtration efficiency. To solve this technical problem, this example discloses the following technical content. Please refer to [link / reference]. Figures 1-7 As shown; a dust absorption device for noodle production includes an absorption cylinder 1 fixedly installed above the processing area. A fan 2 is fixedly installed on the top of the absorption cylinder 1, and the air inlet end of the fan 2 is connected to the upper end of the absorption cylinder 1. A collection seat 3 is threadedly connected to the lower end of the absorption cylinder 1. An air inlet assembly is provided on the outer side of the absorption cylinder 1. A fixing ring 6 is fixedly installed on the upper inner side of the absorption cylinder 1. A first movable plate 7 and a second movable plate 9 are also sealed and slidably installed on the upper inner side of the absorption cylinder 1. The first movable plate 7 and the second movable plate 9 are located on the upper and lower sides of the fixing ring 6, respectively. A first spring 8 is fixedly connected between the fixing ring 6 and the first movable plate 7, and a second spring 10 is fixedly connected between the first movable plate 7 and the second movable plate 9. A pressure regulating assembly is provided on the second movable plate 9. A fixing seat 16 is fixedly installed on the lower inner side of the absorption cylinder 1, and a filter assembly is connected between the first movable plate 7 and the fixing seat 16. A tapping assembly for assisting in cleaning the filter assembly is also provided between the fixing ring 6 and the first movable plate 7.

[0022] The air intake assembly includes an air intake pipe 4 uniformly and fixedly installed on the absorption cylinder 1, and a dust suction hood 5 is fixedly connected to the lower end of the air intake pipe 4. The dust suction hood 5 is arranged in a ring structure. The pressure regulating assembly includes an air hole structure that is uniformly and fixedly installed on the second movable plate 9. A sealing plug 11 is sealed and fitted in the air hole structure. A third spring 12 is fixedly connected between the sealing plug 11 and the second movable plate 9. When the fan 2 is working, the second movable plate 9 drives the first movable plate 7 to move upward under the negative pressure. When the second movable plate 9 cannot move upward, the sealing plug 11 elastically moves upward, allowing air to pass through the air hole structure. The filter assembly includes an air intake pipe 4 uniformly and fixedly installed on the second movable plate 1. A connecting seat 13 is mounted on a movable plate 7, and a mounting seat 14 is threadedly connected to the lower part of the connecting seat 13. A dust collector bag 15 is fixedly connected to the lower part of the mounting seat 14. A rotating seat 17 is evenly and elastically mounted on a fixed seat 16. The rotating seat 17 and the lower end of the dust collector bag 15 are fixedly connected. The connecting seat 13, the dust collector bag 15 and the rotating seat 17 are coaxially arranged. The dust collector bag 15 is initially twisted. During the upward movement of the first movable plate 7, the dust collector bag 15 is pulled to unfold and return to a cylindrical shape. During the unfolding of the dust collector bag 15, the rotating seat 17 on the outer side of its lower end is elastically rotated.

[0023] When dust absorption is required, fan 2 is activated, drawing air from above the second movable plate 9. This causes the second movable plate 9 to move upward under negative pressure. Simultaneously, the second movable plate 9, via the second spring 10, drives the first movable plate 7 to move upward, compressing the first spring 8. At this point, the connecting seat 13 on the first movable plate 7 pulls the upper end of the dust collector bag 15, causing the dust collector bag 15 to gradually straighten. This causes the lower end of the dust collector bag 15 to drive the rotating seat 17 to rotate elastically. When the first movable plate 7 cannot move upward, the sealing plug 11 moves upward under air pressure, allowing air to be delivered through the pore structure on the second movable plate 9. The absorption cylinder 1 can extract dust generated in the processing area through the suction pipe 4 and the dust hood 5, and filter it through the dust collection bag 15. When the fan 2 stops working, the first movable plate 7 will move down and reset. At this time, it can push the airflow to backwash the dust collection bag 15, thereby preventing the dust collection bag 15 from becoming blocked. As the first movable plate 7 moves down and resets, the distance between the upper and lower ends of the dust collection bag 15 can be shortened. At the same time, the rotating seat 17 will rotate elastically and reset, thereby twisting the dust collection bag 15, making wrinkles on the surface of the dust collection bag 15, thereby loosening the dust filtered from the surface of the dust collection bag 15, and further improving the cleaning effect of the dust collection bag 15.

[0024] The tapping assembly includes a guide post 21 fixedly installed on the inner side of the upper end of the absorption cylinder 1, and a spiral guide groove 22 is provided on the outer side of the guide post 21. A movable shaft 23 is rotatably installed through the middle position of the second movable plate 9, and the movable shaft 23 passes through the middle position of the first movable plate 7. The upper parts of the guide post 21 and the movable shaft 23 form a lifting sleeve structure, and a ball bearing 24 is embedded in the upper inner wall of the movable shaft 23. The ball bearing 24 rolls along the guide groove 22. The second movable plate 9 drives the movable shaft 23 to lift and rotate at the same time. A tapping element 25 is evenly fixedly installed on the outer side of the movable shaft 23. When the movable shaft 23 drives the tapping element 25 to rotate, the tapping element 25 intermittently taps the outer side of the dust collector bag 15.

[0025] As the second movable plate 9 moves downward, it can drive the movable shaft 23 to move downward synchronously, causing the ball bearings 24 on the upper inner wall of the movable shaft 23 to roll along the guide groove 22 opened on the outer side of the guide post 21, thereby driving the movable shaft 23 to move downward and rotate at the same time, so that the striking part 25 on the outer side of the movable shaft 23 can intermittently tap different positions of the dust collector bag 15, thereby further improving the cleaning effect.

[0026] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Most existing dust absorption equipment for noodle production only cleans the filtration mechanism, resulting in insufficient recovery of some dust remaining on the inner wall of the equipment. To further solve this technical problem, this example discloses the following technical content: Figures 8-9 As shown; an external toothed ring 18 is fixedly installed on the outer side of the rotating seat 17, and an internal toothed ring 19 is rotatably installed above the fixed seat 16. The external toothed ring 18 and the internal toothed ring 19 are meshed and connected. At the same time, the upper surface of the internal toothed ring 19 is inclined. A cleaning scraper 20 is evenly fixedly installed on the upper surface of the internal toothed ring 19. The cleaning scraper 20 is attached to the inner wall of the absorption cylinder 1. During the rotation of the internal toothed ring 19, the cleaning scraper 20 is driven to scrape off the dust attached to the inner wall of the absorption cylinder 1.

[0027] As the rotating seat 17 rotates, it can drive the outer toothed ring 18 to rotate, so that the outer toothed ring 18 drives the inner toothed ring 19 to rotate synchronously through meshing. This allows the cleaning scraper 20 on the outer side of the inner toothed ring 19 to slide against the inner wall of the absorption cylinder 1, thereby achieving automatic cleaning of the inner wall of the absorption cylinder 1.
