Description

Technical Field

[0001] This application relates to the field of carding machine technology, specifically to a high-efficiency impurity removal structure for carding machines. Background Technology

[0002] Carding machines are used to process cotton fibers and chemical fibers. They belong to textile machinery. According to the spinning process, carding is an important step. The working principle is to open, comb, and remove impurities from the cotton laps sent from the previous process or the oily cotton layer supplied by the cotton box.

[0003] An existing patent (publication number: CN216192951U) discloses a carding machine for removing impurities, including a housing. Both ends of the housing have through-holes at the sides. Multiple rotating drums are rotatably connected to the inner wall of the housing, and a conveying tube is rotatably connected to the inner wall of the housing via bearings. Cotton material is fitted onto the circumferential side walls of the multiple rotating drums and the conveying tube. An exhaust fan is fixed to the side wall of the housing, and the air inlet of the exhaust fan extends into the interior of the housing. An impurity removal device is installed inside the housing. In this device, by setting an adjustment mechanism, the height of the horizontal plate can be adjusted during the rotation of the adjustment rod, thereby adjusting the distance between the scraper and the conveying tube, and between the pressing tube and the corresponding rotating drum. This allows for the processing of cotton materials of varying thicknesses, effectively increasing the applicability of the carding machine. Furthermore, the entire adjustment process is relatively simple and convenient for manual adjustment. The setting of scale lines allows for precise adjustment of the horizontal plate height.

[0004] However, while the distance between the scraper and the conveyor roller can be manually adjusted via an adjustment rod, it still requires manual operation and cannot respond to fluctuations in cotton layer thickness in real time. Furthermore, the adjustment accuracy depends on visual scale lines, which can easily lead to incomplete scraping of thin cotton or excessive compression of thick cotton, damaging the fibers. Secondly, while the exhaust fan expels the gas inside the machine casing to the outside, impurities or cotton lint generated by carding will float inside the casing. Direct discharge can easily pollute the workshop environment, and the accumulation of cotton lint in the workshop can pose safety hazards. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a high-efficiency impurity removal structure for a carding machine, which has advantages such as impurity interception and automatic adjustment, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a high-efficiency impurity removal structure for a carding machine, comprising a machine housing, a conveying roller disposed between the front and rear inner walls of the machine housing, a scraper disposed above the conveying roller, and a drive mechanism disposed above the scraper for driving the scraper to move up and down. An adsorption mechanism is provided on one side of the housing. The adsorption mechanism includes an installation box, which is fixedly embedded in one side of the housing along the width direction. An interception net is provided inside the installation box. The interception net is U-shaped. A discharge pipe is fixedly connected to the front end of the installation box and is coaxially arranged with the arc end of the interception net. A collection box is fixedly connected to the front end of the discharge pipe. An auger plate is rotatably connected between the inner wall of the collection box and the inner rear wall of the installation box. The outer diameter edge of the auger plate is in close contact with the inner wall of the interception net and the inner wall of the discharge pipe.

[0007] Furthermore, the drive mechanism includes a drive housing, which is installed on the inner top wall of the housing along the length of the housing. A bidirectional threaded rod is rotatably connected between the two inner side walls of the drive housing. Moving blocks are threaded to both ends of the bidirectional threaded rod. Both moving blocks are slidably connected to the drive housing. Connecting rods are hinged to the bottom ends of both moving blocks. The bottom end of each connecting rod is hinged to the upper surface of the scraper. One end of the bidirectional threaded rod is fixedly connected to the external motor output end.

[0008] The above solution enables electric adjustment of the distance between the scraper and the conveyor roller, which is much more convenient for users than the existing technology where the threaded rod is located at the top of the machine housing and requires manual adjustment.

[0009] Furthermore, the drive mechanism also includes two sleeves, the top ends of which are fixedly connected to the inner top wall of the housing, and limit rods are slidably inserted into the interior of each sleeve, with the bottom end of each limit rod fixedly connected to the upper surface of the scraper.

[0010] The above solution provides vertical guidance and constraint for the scraper block by setting the sleeve and the limiting rod, preventing the scraper block from shifting horizontally due to the resistance of the cotton material during the lifting and lowering process. This ensures that the scraping surface and the surface of the conveying roller always maintain parallel contact, improving the stability of the cleaning process. During the high-speed operation of the carding machine, the fluctuation of the cotton material thickness can easily lead to uneven force on the scraper block. The guiding structure can avoid local wear or blind spots in cleaning caused by the tilting of the scraper block.

[0011] Furthermore, a distance sensor is installed on the top of one of the limiting rods and the inner top wall of its adjacent sleeve, and the two distance sensors are optically connected.

[0012] The above solution allows for real-time monitoring of the distance between the scraper and the conveyor roller, with the data fed back to the control system to dynamically adjust the scraper height. Compared to the existing technology that uses a scale for visual adjustment, this method significantly improves accuracy.

[0013] Furthermore, inlet and outlet ports are respectively provided on both sides of the housing.

[0014] The above scheme facilitates the input and output of cotton materials.

[0015] Furthermore, the front of the collection box is hinged with a cabinet door via a self-locking hinge.

[0016] With the above solution, the collection box is made of transparent acrylic material, allowing direct observation of the impurity accumulation through a visual window; the self-locking hinges automatically engage when the cabinet door is closed, and users can periodically open the cabinet door to clean the cotton fibers and sediment that have become entangled in the auger plate.

[0017] Furthermore, a centrifugal fan is installed on one side of the collection box, the input end of the centrifugal fan is fixedly connected to one side of the installation box, and a dust filter is fixedly installed on the output end of the centrifugal fan.

[0018] The above methods capture particulate matter, improve the cleanliness of exhaust air, and reduce workshop pollution.

[0019] Furthermore, the filter pore size of the interceptor mesh is 0.3–0.5 mm.

[0020] The above method intercepts short fibers and seed debris while preventing excessive fiber accumulation.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This carding machine features a high-efficiency impurity removal structure. By driving the scraper block to rise and fall with a bidirectional threaded rod, it replaces the traditional manual adjustment method, enabling rapid and precise control of the distance between the scraper block and the conveyor roller. This effectively adapts to dynamic changes in cotton layer thickness, avoiding the problems of incomplete impurity removal for thin materials or fiber damage for thick materials, and significantly improving the applicability and ease of operation of the equipment. When adjusting the distance between the scraper and the conveyor roller, the distance sensor provides real-time feedback on the scraper position data, which, together with the control system, enables dynamic adjustment, eliminates human error caused by visual scale adjustment, ensures stable scraping pressure, and guarantees consistent impurity removal quality. By using a U-shaped interceptor net and auger plates, floating impurities such as cotton fibers, short fibers, and seed scraps inside the machine casing are directed to the collection box, avoiding workshop pollution caused by traditional exhaust ventilation. This facilitates the subsequent separation and recycling of cotton fibers and impurities, promoting resource recycling. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figures 1-6 This embodiment of a high-efficiency impurity removal structure for a carding machine includes a housing 1. Inlet and outlet 7 are respectively provided on both sides of the housing 1 to facilitate the input and output of cotton material. A conveying roller 2 is provided between the front and rear inner walls of the housing 1. A scraper block 3 is provided above the conveying roller 2. A drive mechanism 4 is provided above the scraper block 3 to drive the scraper block 3 to move up and down. The drive mechanism 4 allows adjustment of the distance between the scraper block 3 and the conveying roller 2, suitable for cotton materials of different thicknesses. The drive mechanism 4 includes a drive housing 401, which is installed along the length of the housing 1 on the inner top wall of the housing 1. A bidirectional threaded rod 402 is rotatably connected between the two inner sidewalls of the drive housing 401. The two ends of the bidirectional threaded rod 402 are respectively threaded with moving blocks 403. Both moving blocks 403 are slidably connected to the drive housing 401. The bottom ends of both moving blocks 403 are hinged with connecting rods 404. The bottom end of each connecting rod 404 is hinged to the upper surface of the scraper block 3. One end of the bidirectional threaded rod 402 is fixedly connected to the external motor output end, which can realize the electric distance adjustment between the scraper block 3 and the conveying roller 2. Compared with the prior art where the threaded rod is set at the top of the housing 1 and needs to be manually adjusted, it effectively improves the convenience of the user.

[0026] The drive mechanism 4 also includes two sleeves 405. The top ends of both sleeves 405 are fixedly connected to the inner top wall of the housing 1. Limiting rods 406 are slidably inserted into the interior of each sleeve 405. The bottom end of each limiting rod 406 is fixedly connected to the upper surface of the scraper block 3. The sleeves 405 and limiting rods 406 provide vertical guidance and constraint for the scraper block 3, preventing horizontal displacement due to cotton resistance during lifting and lowering. This ensures that the scraping surface and the surface of the conveying roller 2 remain in parallel contact, improving the stability of the impurity removal process. During high-speed operation of the carding machine, the cotton material... Thickness fluctuations can easily lead to uneven force on the scraper block 3. The guide structure can avoid local wear or blind spots in the cleaning caused by the tilting of the scraper block 3. One of the limiting rods 406 has a distance sensor 6 installed on the top of its upper end and the inner top wall of its adjacent sleeve 405. The two distance sensors 6 are optically connected (the distance sensor 6 is a laser displacement sensor, forming a through-beam optical path detection structure) to monitor the change in the distance between the scraper block 3 and the conveying roller 2 in real time and feed the data back to the control system to realize dynamic adjustment of the height of the scraper block 3. Compared with the existing technology of visual adjustment by scale, the accuracy is effectively improved.

[0027] An adsorption mechanism 5 is provided on one side of the housing 1. The adsorption mechanism 5 includes a mounting box 501, which is fixedly embedded in one side of the housing 1 along its width. An intercepting mesh 502 is provided inside the mounting box 501. The filter pore size of the intercepting mesh 502 is 0.3–0.5 mm (mesh wire diameter 0.15 mm, open area ≥45%). Through the above arrangement, short fibers and seed dust are intercepted, while avoiding excessive fiber accumulation. The intercepting mesh 502 is U-shaped. A discharge pipe 503 is fixedly connected to the front end of the mounting box 501 and is coaxially arranged with the arc-shaped end of the intercepting mesh 502. The front end of the discharge pipe 503 is fixedly connected to... There is a collection box 504, and an auger plate 505 is rotatably connected between the inner wall of the collection box 504 and the inner rear wall of the mounting box 501 (the rotating shaft of the auger plate 505 is fixedly connected to the output end of the motor). The outer diameter edge of the auger plate 505 is in close contact with the inner wall of the interception net 502 and the inner wall of the discharge pipe 503. Through the above settings, floating impurities or cotton fibers generated by carding inside the machine casing 1 can be intercepted. With the auger plate 505, cotton fibers and impurities can be continuously pushed into the collection box 504 to avoid being discharged into the external environment. By separating the impurities in the cotton fibers, the cotton fibers can be reused.

[0028] The front of the collection box 504 is hinged to a cabinet door 8 via a self-locking hinge. The self-locking hinge is a type of hinge with an automatic locking function. The collection box 504 is made of transparent acrylic material, allowing direct observation of the impurity accumulation state through a viewing window. The self-locking hinge automatically engages when the cabinet door 8 is closed. Users can periodically open the cabinet door 8 to clean the cotton fibers and sediment deposited impurities entangled in the auger plate 505. A centrifugal fan 9 is installed on one side of the collection box 504. The input end of the centrifugal fan 9 is fixedly connected to one side of the mounting box 501. A dust filter 10 is fixedly installed on the output end of the centrifugal fan 9. The dust filter 10 is a prior art filter for filtering dust, which will not be described in detail here. It captures fine dust, improves the cleanliness of the exhaust air, and reduces workshop pollution.

[0029] The working principle of the above embodiment is as follows: the cotton material enters the machine housing 1 through the inlet and outlet 7 on both sides. The scraper block 3 is located above the conveyor roller 2 and is adjusted to the initial working height by the drive mechanism 4 to maintain a suitable distance from the surface of the conveyor roller 2. The bottom end of the moving block 403 is hinged to the scraper block 3 through the connecting rod 404, which pushes the scraper block 3 to rise and fall vertically, thereby achieving precise adjustment of the distance between it and the conveyor roller 2. The sleeve 405 and the limiting rod 406 can limit the movement of the scraper block 3 when it rises and falls, ensuring that the scraper block 3 only moves in the vertical direction. The distance sensor 6 detects the distance between the top of the limiting rod 406 and the inner top wall of the sleeve 405 in real time, indirectly reflecting the distance between the scraper block 3 and the conveyor roller 2. After the centrifugal fan 9 is started, impurities such as cotton fibers, short fibers, and seed dust floating inside the casing 1 are drawn into the installation box 501 with the airflow. The intercepting net 502 has a U-shaped structure, with its arc-shaped end coaxial with the discharge pipe 503. The filter pore diameter is 0.3–0.5 mm, which can intercept small impurities such as short fibers and seed dust, while allowing air to pass through. The auger plate 505 rotates between the installation box 501 and the collection box 504. Its outer edge is in close contact with the inner wall of the intercepting net 502 and the inner wall of the discharge pipe 503. When rotating, the auger plate 505 continuously pushes the impurities attached to and captured by the intercepting net 502 to the discharge pipe 503, and finally into the collection box 504. The centrifugal fan 9 extracts the gas from the installation box 501, which first passes through the dust filter 10 to capture residual micro-dust particles, ensuring that the cleanliness of the discharged air meets the standards.
