Description

Technical Field

[0001] This solution belongs to the technical field of pipeline cleaning equipment, specifically involving a cotton conveying pipeline cleaning device. Background Technology

[0002] Cotton conveying pipes are specialized pipeline equipment used in the carding process of the textile industry to transport cotton fibers or remove cotton dust and short fibers. They are usually made of metal or wear-resistant PVC material. One end is connected to the cotton box, doffer, or licker-in roller of the cotton conveying machine, and the other end is connected to the cotton fiber collection device or the equipment of the next process (such as the drawing frame). The loose cotton fibers are smoothly transported from the cotton conveying machine and the opening machine to the drawing frame and the roving frame through negative pressure airflow.

[0003] During long-term use, cotton fibers tend to accumulate on the inner wall of the cotton conveying pipe, while cotton dust and metal debris accumulate on the outer wall. The accumulation of fibers on the inner wall can reduce the pipe diameter and obstruct airflow, leading to a decrease in conveying efficiency or even blockage. Pollutants on the outer wall can easily spread with the airflow in the workshop and pollute the environment. Therefore, in order to maintain the normal conveying of the cotton conveying pipe, the workshop needs to clean the cotton conveying pipe regularly.

[0004] See the existing publication (announcement) number CN201485565U, which discloses a dust collection device for textile machinery, including a suction fan connected to the main air duct, the outer side of the vent hood of the licker-in roller being connected to the cotton suction hopper below the licker-in roller via a connecting pipe, the cotton suction hopper being connected to the main air duct via a branch air duct, and the inner side of the vent hood of the roller being connected to the branch air duct via a connecting pipe; the branch air duct is equipped with a fireproof gate and is a three-dimensional Z-shaped pipe.

[0005] For example, the aforementioned dust collection device connects to the main duct via a suction hopper and other air ducts, drawing in fallen debris, cotton, and dust-laden air into the dust filter chamber for processing, achieving automatic collection of fallen cotton and air filtration. However, when the air duct is directly applied to the cotton conveying pipe for cleaning, the suction hopper and branch air ducts are fixed structures, resulting in poor fit between the curved contours of the cotton conveying pipe and creating cleaning dead zones, leading to poor cleaning results. Utility Model Content

[0006] The purpose of this solution is to provide a cotton conveying pipe cleaning device to solve the problem that existing vacuuming devices have poor cleaning effects on cotton conveying pipes.

[0007] To achieve the above objectives, this solution provides a cotton conveying pipe cleaning device, including a vacuum cleaner and a suction nozzle, wherein the suction nozzle is connected to the vacuum cleaner via a suction rod, and further includes: The support is a ring-shaped support, and the suction nozzle is located on the inner side of the support; The roller is located on the inner side of the support and rolls in contact with the outer wall of the cotton conveying pipe.

[0008] The principle and effect of this solution are as follows: the ring-shaped support adapts to the outer wall of the cotton conveying tube, so that the suction nozzle and the outer wall of the cotton conveying tube are in close contact. When in use, the vacuum cleaner provides negative pressure to the suction nozzle through the suction rod. The manual hand holds the suction rod, and the support and suction nozzle move along the length of the cotton conveying tube under the drive of the roller, thereby cleaning the outer wall of the cotton conveying tube.

[0009] Furthermore, it also includes a cleaning component, which includes a drive disc and a movable rod. The drive disc is coaxially and fixedly connected to the roller, and the movable rod is disposed on the drive disc. One end of the movable rod is connected to a striking ball, which is used to strike the outer wall of the cotton conveying tube.

[0010] The principle and effect of this solution are as follows: During the long-term transport of cotton fibers, the inner wall of the cotton conveying pipe is prone to accumulating fibers due to electrostatic adsorption, which reduces the inner diameter of the pipe and hinders airflow. In this solution, as the roller moves along the cotton conveying pipe, the drive disc, which is coaxially fixed with the roller, rotates synchronously with the roller, thereby driving the movable rod to rotate. This causes the striking ball to periodically strike the outer wall of the cotton conveying pipe; the vibration generated by the striking is transmitted through the pipe wall to the inner wall, causing the accumulated fibers to fall off. Subsequently, a blower blows air onto one end of the cotton conveying pipe to clean the inner wall of the pipe.

[0011] Furthermore, the drive disk is coaxially provided with a fixed disk, the fixed disk is fixedly connected to a support plate for supporting the roller, the edge of the fixed disk is eccentrically provided with a first hinge point, the free end of the movable rod is hinged to the first hinge point, the free end of the movable rod is fixedly connected to a limit rod, the edge of the drive disk is eccentrically provided with a second hinge point, and the limit rod is slidably connected to the second hinge point.

[0012] The principle and effect of this solution are as follows: Since the suction rod is moved manually, and in order to ensure thorough cleaning, the cotton conveying pipe cleaning device generally needs to be moved slowly. However, slow movement will directly reduce the rotation speed of the rollers that roll against the outer wall of the cotton conveying pipe on the inner side of the support. The drive disc, which is fixed coaxially with the rollers, rotates synchronously with the rollers, and its rotation speed also slows down. This, in turn, slows down the rotation speed of the movable rod connected to the drive disc. Due to insufficient movement speed, the striking ball at one end of the movable rod generates less force when striking the outer wall of the cotton conveying pipe. When the vibration is transmitted to the inner wall of the pipe, it is difficult to effectively shake off the accumulated cotton, thus affecting the cleaning effect. This solution, through the aforementioned structure, is similar to a variant of a crank-slider mechanism. By using the double eccentricity of the fixed plate and the drive plate, and the sliding constraint of the limiting rod within the second hinge point, the movement trajectory of the movable rod changes, creating a quick-return characteristic. Even if the roller rotates slowly due to the slow movement of the cleaning device, the movable rod will still experience a period of rapid speed increase due to the quick-return characteristic during rotation. During this period, the striking ball moves rapidly with the movable rod, generating a large centrifugal force at the moment of slow-to-fast turn, increasing the striking force on the outer wall of the cotton conveying pipe, producing greater vibration, and more effectively shaking off the accumulated cotton from the inner wall of the pipe. Even if the cleaning device moves slowly, the cleaning effect can still be guaranteed.

[0013] Furthermore, a drive rod is hinged to one end of the movable rod near the striking ball, and a slider is hinged to the free end of the drive rod. The inner side of the slider is in contact with the outer wall of the cotton conveying tube.

[0014] The principle and effect of this solution are as follows: In the previous solution, only the suction nozzle adsorbed the cotton dust on the outer wall of the cotton conveying tube. However, for cotton dust that adheres to the tube wall due to factors such as static electricity or oil stains, negative pressure adsorption alone is insufficient to effectively remove it, leaving some cotton dust that affects the cleaning effect. In this solution, when the movable rod rotates, it drives the drive rod to rotate, which in turn drives the slider to move horizontally back and forth. With the help of the quick-return characteristic structure, the slider moves faster when moving towards the drive plate (return stroke). In this way, the slider can scrape off the cotton dust on the outer wall of the tube during rapid movement, especially the firmly adhered cotton dust. Combined with the negative pressure adsorption of the suction nozzle, it can effectively clean the outer wall of the cotton conveying tube.

[0015] Furthermore, the striking ball is connected to a spring, and the free end of the spring is fixedly connected to one end of the movable rod.

[0016] The principle and effect of this solution are as follows: when the movable rod drives the striking ball to move and strike the outer wall of the cotton conveying tube, the deformation of the spring can adapt to the small protrusions or depressions that may exist on the outer wall of the cotton conveying tube, so that the striking ball can only make point contact with the outer wall of the cotton conveying tube, thus avoiding the movable rod from getting stuck.

[0017] Furthermore, the free end of the limiting rod is equipped with an impeller.

[0018] The principle and effect of this solution are as follows: After the slider scrapes away the cotton dust, the cotton dust in the upper part of the cotton conveying pipe (especially the top) is difficult to fall off naturally like the cotton dust in the lower part of the pipe, and remains on the pipe wall at the top of the pipe. In this solution, during the process of the slider scraping away the cotton dust on the outer wall of the cotton conveying pipe during the return stroke, due to the cooperation of the limiting rod, the movable rod, and the drive disc, when the slider moves to the return stroke stage, the limiting rod rotates to a position close to the slider. Through the eccentricity of the drive disc and the fixed disc and the sliding cooperation between the limiting rod and the second hinge point, the connection end between the limiting rod and the impeller also has a quick return characteristic when rotating to this area. The rotation speed of this end will increase during this stage, so that the impeller obtains a large centrifugal force, generates airflow, and blows it directly at the cotton dust that the slider has just scraped away, blowing the cotton dust above the cotton conveying pipe off and preventing residue.

[0019] Furthermore, a groove is provided inside the slider, and a driving block and a cleaning block are provided inside the groove. A tension spring is connected to the top of the cleaning block, and the free end of the tension spring is fixedly connected to the groove. A compression spring is connected to the side wall of the driving block, and the compression spring is fixedly connected to the groove. The bottom of the driving block and the top of the cleaning block are both wedge-shaped. The driving block is used to drive the cleaning block to move toward the outer wall of the cotton conveying tube.

[0020] The principle and effect of this solution are as follows: When moving the cleaning device with a handheld suction rod, if the slider remains in close contact with the outer wall of the cotton conveying tube to scrape away cotton dust during the horizontal reciprocating motion, it will generate continuous and significant friction, making it difficult for workers to push the device along the length of the tube and increasing the operational difficulty. In this solution, when the slider moves with the movable rod, it only experiences a relatively fast speed during the return stroke due to its rapid return characteristic. At this point, the drive block is subjected to a large centrifugal force, overcoming the spring force and moving towards the cleaning block. The inclined surface of the wedge structure then pushes the cleaning block to overcome the tension spring force and move towards the outer wall of the cotton conveying tube. This ensures that the cleaning block only makes close contact with the outer wall of the tube and scrapes away cotton dust during the moment of rapid return. During other movement phases, the slider moves slower, the drive block resets under the action of the spring, and the cleaning block separates from the outer wall of the tube under the action of the tension spring. This avoids the continuous friction caused by constant close contact, ensuring dust removal from the cotton conveying tube while reducing the resistance that makes pushing the device along the length of the tube difficult.

[0021] Furthermore, the bracket is connected to a vertically arranged support rod, and the free end of the support rod is fixedly connected to a horizontally arranged guide rail. The slider is slidably connected to the guide rail. The limiting rod has a through groove arranged along its length direction, and the second hinge point is slidably arranged in the through groove.

[0022] The principle and effect of this solution are as follows: the guide rail is used to provide positioning and guidance for the horizontal reciprocating motion of the slider; the through groove cooperates with the second hinge point to constrain the movement of the limit rod and prevent it from dislodging.

[0023] Furthermore, it also includes a sleeve, in which the bracket and cleaning components are both disposed, and the suction nozzle is disposed at the bottom of the sleeve; one end of the sleeve is provided with a sealing element that mates with the outer wall of the cotton conveying tube.

[0024] The principle and effect of this solution are as follows: a relatively closed cleaning space is formed by the sleeve and the seal to prevent the cotton dust raised during the cleaning process from spreading into the workshop environment; when the cotton dust scraped off falls to the inner side of the sleeve, it is sucked into the vacuum cleaner through the nozzle.

[0025] Furthermore, the number of cleaning components is two sets, and they are symmetrically arranged on both sides of the cotton conveying tube.

[0026] The principle and effect of this solution is that the two sets of cleaning components can simultaneously clean the upper and lower (or left and right) sides of the cotton conveying tube. Attached Figure Description

Detailed Implementation

[0029] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Example 1: Please see Figures 1-3 This embodiment discloses a cotton conveying pipe cleaning device, including a vacuum cleaner 1, a nozzle 2, a suction rod 3, a bracket 4, and rollers 5. The vacuum cleaner 1 is an industrial-grade portable negative pressure vacuum cleaner with a rated suction power of 22 kPa, which can meet the effective adsorption requirements for cotton dust and other impurities. The suction rod 3 is a 2mm thick telescopic steel pipe, with a length designed to be 1.6-2.2m depending on the installation height of the cotton conveying pipe 6 in the workshop. One end of the suction rod 3 is sealed to the suction port of the vacuum cleaner 1 via a corrugated pipe, and the other end is connected to the nozzle 2 via three sets of equal-diameter corrugated pipes. The bracket 4 is an arc-shaped lightweight aluminum alloy structure that can be fitted onto the outside of the cotton conveying tube 6 without causing jamming. The number of suction nozzles 2 is set to several, evenly distributed along the inner circumference of the bracket 4. The opening end of each suction nozzle 2 faces the outer wall of the cotton conveying tube 6 and maintains a contact distance of 3-4mm with the outer wall of the cotton conveying tube 6. This distance can reduce suction resistance while minimizing cleaning dead corners and avoiding cotton dust residue caused by poor contact between the suction nozzle 2 and the tube wall. There are two rollers 5, both located inside the bracket 4. Each roller 5 is fixedly connected to the inner wall of the bracket 4 via an L-shaped support plate 51. The top of the support plate 51 is welded to the inner wall of the bracket 4 by argon arc welding or compression spring. The side wall of the support plate 51 is rotatably connected to the roller 5 via a rotating shaft. A copper bushing is provided between the rotating shaft and the roller 5 to reduce rotational friction. The outer circumference of the roller 5 is covered with a nitrile rubber anti-slip layer. The surface of the rubber layer is pressed with diamond-shaped anti-slip patterns to ensure stable rolling contact between the roller 5 and the outer wall of the cotton conveying pipe 6, preventing slippage and deviation during device movement.

[0030] Example 2: The difference between this embodiment and the previous embodiment is that it achieves further cleaning of the accumulated cotton on the inner and outer walls of the cotton conveying pipe 6. Please refer to [link / reference]. Figures 4-9 This device is equipped with two sets of cleaning components 7. The two sets of components are symmetrically distributed on the inner side of the support 4 along the axis of the cotton conveying pipe 6 (corresponding to the upper and lower sides of the cotton conveying pipe 6 respectively). They have the same structure and work synchronously, which can improve the efficiency of shaking off accumulated cotton on the inner wall.

[0031] Please see Figure 5 and Figure 6The sleeve 8 is a cylindrical stainless steel tube with an inner diameter larger than the outer diameter of the bracket 4. The bracket 4 and the cleaning component 7 are both located inside the sleeve 8. The bottom of the sleeve 8 has an installation hole that matches the nozzle 2. After the nozzle 2 branch tube passes through the installation hole, it is sealed to the inner wall of the sleeve 8 by a rubber sealing ring. A sealing element 9 (this is the prior art) is provided on the left side of the sleeve 8. The sealing element 9 is mainly used to hold and fix the outer wall of the cotton conveying tube 6 and to form a relatively closed cleaning space between the sleeve 8 and the cotton conveying tube 6, so as to prevent cotton dust from spreading to the workshop environment during the cleaning process. At the same time, the fallen cotton dust can be concentrated and sucked into the vacuum cleaner 1 by the nozzle 2.

[0032] Please see Figure 7 The cleaning component 7 includes a drive plate 71, a movable rod 72, a striking ball 73, a fixed plate 74, a limit rod 75, a drive rod 76, and a slider 77. The drive plate 71 has a shaft hole in the center that matches the rotating shaft of the roller 5. It is fixedly connected to the rotating shaft of the roller 5 by a flat key, so that the drive plate 71 rotates synchronously when the roller 5 rotates. The fixed plate 74 is coaxially arranged with the drive plate 71 and is fixedly connected to the support plate 51 that supports the roller 5 by four sets of M4 bolts. The fixed plate 74 remains stationary when the drive plate 71 rotates. The fixed plate 74 has a first hinge point 741 eccentrically located on its edge. The first hinge point 741 is a cylindrical convex shaft. The movable rod 72 is a long rod in the shape of a strip. One end of the rod has a hinge hole that matches the first hinge point 741. The rod is hinged to the first hinge point 741 through the hinge hole and can rotate around the first hinge point 741 (rotation angle range 0-360°). The other end of the movable rod 72 is connected to the striking ball 73 through a spring 731. The spring 731 is a cylindrical compression spring. One end of the spring 731 is fixed to the end of the movable rod 72 by argon arc welding, and the other end is fixed to the striking ball 73 through a threaded connector (not shown). The striking ball 73 is a solid stainless steel ball. The free end of the movable rod 72 is also fixed with a limiting rod 75 by argon arc welding. The limiting rod 75 is a long, strip-shaped rod, set along the same central axis as the movable rod 72. A rectangular through groove 751 is formed on the limiting rod 75 along its length. The width of the through groove 751 is adapted to the diameter of the second hinge point 711 provided on the edge of the drive disk 71. The second hinge point 711 is a cylindrical convex shaft, and it is located on both sides of the axis of the two disks (i.e., both are located at the edge of the two disks) respectively with the first hinge point 741. The second hinge point 711 is slidably disposed in the through groove 751. This creates a transmission structure similar to a crank-slider mechanism variant. This structure allows both the movable rod 72 and the limiting rod 75 to have quick-return characteristics. Even if the device is manually pushed slowly, resulting in low rotational speeds for the roller 5 and drive disc 71 (e.g., ≤10 r / min), the movable rod 72 will still experience a sudden speed increase under the quick-return characteristic. At this time, the striking ball 73 moves rapidly with the movable rod 72, generating a large centrifugal force at the instant of speed change, increasing the striking force on the outer wall of the cotton conveying pipe 6. The vibration generated by the striking is transmitted through the pipe wall to the inner wall (e.g., ...). Figure 9As shown, it can shake off the cotton fibers that are attracted by static electricity on the inner wall. Then, a high-pressure airflow of 0.3MPa is introduced into one end of the cotton conveying pipe 6, which can blow the shaken-off fibers out from the other end, thus cleaning the inner wall.

[0033] Please continue reading. Figure 7 To clean stubborn cotton dust adsorbed by oil or strong static electricity on the outer wall of the cotton conveying pipe 6, a drive rod 76 is hinged to one end of the movable rod 72 near the striking ball 73 via a pin. The drive rod 76 is a long rod, and a slider 77 is hinged to its free end via another pin. The slider 77 is a block structure made of polytetrafluoroethylene, with an inner wall that is an arc-shaped surface adapted to the outer wall of the cotton conveying pipe 6 (the radius of the arc is the same as the radius of the outer wall of the cotton conveying pipe 6), and a dovetail groove (not shown) on the outer wall. A vertically arranged support rod 79 is fixed to the bracket 4 by argon arc welding. The support rod 79 is a stainless steel rod with a length of 120mm. A horizontally arranged dovetail-shaped guide rail 710 is fixed to its free end by argon arc welding. The slider 77 is slidably connected to the guide rail 710 through the dovetail groove. The guide rail 710 provides positioning and guidance for the horizontal reciprocating motion of the slider 77, preventing the slider 77 from deviating. When the movable rod 72 moves, it drives the drive rod 76 to swing back and forth, which in turn pushes the slider 77 to move horizontally back and forth along the guide rail 710. Utilizing the quick-return characteristic of the movable rod 72, the slider 77 moves faster when moving towards the drive disc 71 (return stroke). Its inner arc-shaped surface can quickly scrape away stubborn cotton dust from the outer wall of the cotton feeding tube 6, and in conjunction with the negative pressure suction of the suction nozzle 2, it improves the cleaning effect on the outer wall. Furthermore, a rectangular groove 771 (such as...) is provided on the inner side of the slider 77. Figure 7(As shown in the enlarged schematic diagram), a drive block 772 and a cleaning block 773 are provided in the groove 771. The cleaning block 773 is a rectangular polytetrafluoroethylene block. Cleaning cotton is provided on the inner side of the cleaning block 773 (the side closest to the cotton conveying pipe 6). The top left side of the cleaning block 773 is fixedly connected to the top wall of the groove 771 by a tension spring 774. In its natural state, the cleaning block 773 is pulled away from the outer wall of the cotton conveying pipe 6 to avoid friction with the pipe wall during non-working periods. The drive block 772 is a rectangular polytetrafluoroethylene block located above the cleaning block 773. The right side of the drive block 772 is fixedly connected to the side wall of the groove 771 by a compression spring 775. In its natural state, the compression spring 775 drives the drive block 772 away from the cleaning block 773. Both the bottom of the drive block 772 and the top of the cleaning block 773 are machined into 35° wedge-shaped surfaces, and the two wedge-shaped surfaces fit together. When the slider 77 returns at a relatively fast speed, the drive block 772 moves towards the cleaning block 773 under the action of centrifugal force, overcoming the elastic force of the compression spring 775. The wedge-shaped surfaces squeeze and push the cleaning block 773 towards the wall of the cotton conveying pipe 6, overcoming the elastic force of the tension spring 774, so that the cleaning cotton of the cleaning block 773 is in close contact with the pipe wall, enhancing the effect of scraping off stubborn cotton dust. In other stages, the slider 77 moves at a slower speed, the drive block 772 resets under the action of the compression spring 775, and the cleaning block 773 also separates from the pipe wall under the action of the tension spring 774, avoiding friction throughout the process, increasing the movement resistance of the device, and reducing the intensity of manual operation. It should be noted that, since the movable rod 72, the limiting rod 75, the first hinge point 741, the second hinge point 711, the drive rod 76 and the slider 77 need to be set as a crank-slider structure with quick-return characteristics, those skilled in the art can adaptively adjust the length of the above structure, the hinge point and the length of the through groove 751 so that the above structure has quick-return characteristics during the return stroke.

[0034] Please continue reading. Figure 7 The free end of the limiting rod 75 is equipped with an impeller 78, which is a plastic six-bladed impeller. The central shaft of the impeller 78 is interference-fitted with the inner ring of the miniature bearing, and the outer ring of the bearing is interference-fitted with the mounting hole opened at the free end of the limiting rod 75. When the slider 77 returns to scrape away the cotton dust, the limiting rod 75 rotates with the movable rod 72 to a position close to the slider 77. Due to the rapid return characteristic, the speed of this end increases, driving the impeller 78 to rotate at high speed and generating airflow towards the pipe wall (such as...). Figure 8 As shown in the figure, the cotton dust remaining in the upper part (especially the top) of the cotton conveying tube 6 can be blown off, so as to avoid the accumulation of cotton dust and affect the cleaning effect.

[0035] The workflow of this embodiment is as follows: The sleeve 8 (with built-in support 4 and cleaning component 7) is fitted onto the starting end of the cotton conveying tube 6 to be cleaned. The position of the sleeve 8 is adjusted so that the sealing element 9 fits tightly against the outer wall of the cotton conveying tube 6, ensuring a closed space is formed inside the sleeve 8 to prevent cotton dust from spilling out during subsequent cleaning. At this time, the roller 5 inside the support 4 naturally contacts the outer wall of the cotton conveying tube 6, and the suction nozzle 2 maintains a 3-4 cm contact distance with the outer wall of the cotton conveying tube 6. Then, the device is started for cleaning: the vacuum cleaner 1 is turned on to generate a negative pressure of 22 kPa. This negative pressure is transmitted to the suction nozzle 2 through the suction rod 3, and the suction nozzle 2 begins to absorb cotton dust, metal fragments, and other impurities from the outer wall of the cotton conveying tube 6. The person holds the suction rod 3 at the middle position and slowly pushes the sleeve 8 along the length of the cotton conveying tube 6 (pushing speed controlled at 0.1-0.2 m / s). At this time, the roller 5 rolls along the outer wall of the cotton conveying tube 6, driving the drive disc 71 to rotate synchronously. During the rotation of the drive disk 71, the second hinge point 711 slides in the through groove 751 of the limit rod 75, driving the limit rod 75 and the movable rod 72 to move around the first hinge point 741. Due to the eccentric setting of the fixed disk 74 and the drive disk 71, the movable rod 72 forms a quick-return characteristic motion trajectory. During the rapid return phase, the movable rod 72 drives the striking ball 73 to move rapidly and strike the outer wall of the cotton conveying tube 6. The vibration generated by the striking is transmitted through the tube wall to the inner wall of the cotton conveying tube 6, shaking off the cotton fibers accumulated on the inner wall. At the same time, the movement of the movable rod 72 drives the drive rod 76 to swing back and forth, driving the slider 77 to move horizontally back and forth along the guide rail 710. When the slider 77 returns (its speed is faster due to the rapid return characteristics), the drive block 772 pushes the cleaning block 773 to contact the outer wall of the cotton conveying tube 6 under the action of centrifugal force. The cleaning cotton of the cleaning block 773 scrapes off the stubborn cotton dust on the outer wall, and the scraped cotton dust is immediately absorbed by the suction nozzle 2. During this process, the impeller 78 at the free end of the limit rod 75 rotates at high speed with the limit rod 75, and the airflow generated blows off the cotton dust remaining in the upper part of the cotton conveying tube 6, so that the outer wall is cleaned without dead corners. After the sleeve 8 is pushed to the end of the cotton conveying tube 6, turn off the vacuum cleaner 1 and remove the sleeve 8 from the end of the cotton conveying tube 6. If it is necessary to clean the accumulated cotton fibers shaken off the inner wall of the cotton conveying tube 6, the high-pressure air hose (output pressure 0.3MPa) can be connected to one end of the cotton conveying tube 6, and the high-pressure air valve can be opened. The high-pressure airflow will flow along the inside of the cotton conveying tube 6, blowing the shaken-off accumulated cotton fibers out from the other end of the cotton conveying tube 6, thus completing the inner wall cleaning. Finally, perform a final check of the device: clean the dust collection chamber of the vacuum cleaner 1 and empty the collected cotton dust and impurities; check the condition of each component of the device, and confirm that the nozzle 2 is not blocked and the cleaning cotton of the cleaning block 773 is not excessively worn, etc.
