Description

Technical Field

[0001] The present invention relates to the technical field of fabric production, and more specifically, to a cleaning device and cleaning method for rotor-spun fabric production. Background Art

[0002] During the production process of rotor spinning, after the fiber raw materials go through processes such as opening, carding, and conveying, they are drawn into yarns by high-speed air flow. This process will generate a large amount of free fibers, short fibers, and dust. If these impurities cannot be removed in time, it will not only reduce the quality of the spun yarn, but also accumulate inside the equipment, affecting the spinning stability and increasing the equipment maintenance frequency. Traditional cleaning methods mainly rely on manual cleaning or fixed dust collection devices, which have problems such as many cleaning dead corners and low efficiency.

[0003] To solve this technical problem, a touring suction-blow cleaning machine has emerged. This type of equipment usually moves along the production line track and removes fiber impurities by combining negative pressure dust collection and air flow blowing. However, existing equipment generally has defects such as limited dust collection range, insufficient crushing ability, and easy clogging of the filter net. Especially when dealing with fiber impurities in different accumulation forms, it often requires shutting down to clean the filter net, seriously affecting production efficiency. In addition, the dust collection pipes of traditional cleaning machines are mostly of fixed design and are difficult to adapt to the cleaning requirements of different height areas of rotor spinning equipment, resulting in uneven cleaning effects. Therefore, professionals in this field have provided a cleaning device and cleaning method for rotor-spun fabric production to solve the above-mentioned problems. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a cleaning device and cleaning method for rotor-spun fabric production.

[0005] To solve the above problems, the present invention adopts the following technical solutions;

[0006] A cleaning device for rotor-spun fabric production includes a cleaning machine housing and a cyclone separator installed inside it. An exhaust cavity is opened on the right side of the cleaning machine housing, and a centrifugal fan is fixedly installed inside the exhaust cavity. The exhaust end of the cyclone separator is connected to the inside of the exhaust cavity through a sealed pipe. A processing cavity is opened inside the cleaning machine housing, and the intake end of the cyclone separator is located inside the processing cavity. A dynamic gradient filtration system is arranged inside the processing cavity, and the dynamic gradient filtration system is located on top of the cyclone separator. The front and back of the cleaning machine housing are both equipped with a first dust suction pipe, a second dust suction pipe, and a third dust suction pipe. The first dust suction pipe, the second dust suction pipe, and the third dust suction pipe are all connected to the inside of the cleaning machine housing. An infinitely adjustable component and an air-driven crushing component are installed inside each of the first dust suction pipe, the second dust suction pipe, and the third dust suction pipe;

[0007] The described dynamic gradient filtration system includes a sealing frame, which is fixedly installed on the inner wall of the processing chamber. Inside the housing of the cleaning machine, there are two driving motors. The output shaft of the driving motor penetrates and extends into the interior of the processing chamber. A synchronous shaft is fixedly installed on the output shaft of the driving motor. Two synchronous pulleys are fixedly installed on the synchronous shaft. A synchronous belt is sleeved on the synchronous pulley. The side of the synchronous belt is in contact with the inner wall of the processing chamber. On the opposite sides of the two synchronous belts, there is a dynamic filter screen. Inside the processing chamber, there is a recovery chamber, which is located in front of and behind the dynamic filter screen. On the inner wall of the processing chamber, there are two sealing and opening / closing components, which are located on the top of the dynamic filter screen. An auxiliary component is installed on the synchronous shaft;

[0008] The sealing and opening / closing component includes an installation groove, which is opened on the inner wall of the processing chamber. A sealing strip is slidably installed on the inner wall of the installation groove. The bottom end of the sealing strip is in contact with the top of the dynamic filter screen. An electromagnet is fixedly installed on the inner wall of the installation groove. At the bottom of the electromagnet, there is a magnetic plate magnetically connected to it, and the magnetic plate is installed on the top of the sealing strip;

[0009] The auxiliary component includes a return pipe, which is rotatably connected to one end of the synchronous shaft away from the driving motor. The other end of the return pipe penetrates and extends into the interior of the exhaust chamber. An electric control valve is fixedly installed on the return pipe. On the outer side of the part of the synchronous shaft between two adjacent synchronous pulleys, there are evenly distributed air holes;

[0010] The air-driven crushing component includes a connecting flange plate, which is detachably connected to the nozzle position of the suction pipe. A rotating main shaft is rotatably installed on the connecting flange plate. On the side of the rotating main shaft, there are evenly distributed eddy current blades.

[0011] As a further description of the above technical solution: The rotating main shaft is in a hollow state, and the surface of the eddy current blade is provided with micron-level shark tooth-shaped protrusions.

[0012] As a further description of the above technical solution: On the inner wall of the exhaust chamber, there is an air guide cover, and the return pipe is located inside the air guide cover.

[0013] As a further description of the above technical solution: The stepless adjustment component includes a folding sleeve. The two ends of the folding sleeve are installed on the suction pipe through flange plates. A threaded sleeve is installed on the top of the folding sleeve. The bottom end of the folding sleeve is rotatably connected to a threaded shaft, and the top end of the threaded shaft is located inside the threaded sleeve and is threadedly connected to the inner wall of the threaded sleeve.

[0014] As a further description of the above technical solution: a limit sleeve and a sliding rod are respectively installed at the top and bottom of the folding sleeve, and the limit sleeve is sleeved on the sliding rod.

[0015] As a further description of the above technical solution: inspection plates are detachably connected to the front and back of the cleaning machine housing, the inspection plates shield the recovery chamber, and a one-way exhaust valve is installed on the inspection plates.

[0016] As a further description of the above technical solution: the blade thicknesses of multiple eddy current blades in the first dust suction pipe, the second dust suction pipe and the third dust suction pipe gradually become smaller in turn, and the blade thickness of the eddy current blade in the second dust suction pipe is greater than the blade thicknesses of the eddy current blades in the second dust suction pipe and the third dust suction pipe.

[0017] A cleaning method for a cleaning device used in the production of rotor-spun fabrics includes the following steps:

[0018] S1. The cleaning machine housing moves along the track to a designated position on the production line. The first dust suction pipe is automatically lowered to a certain distance from the ground through the folding sleeve. The threaded sleeve of the stepless adjustment assembly rotates synchronously, driving the limit sleeve to lock the height. At the same time, the stepless adjustment assemblies in the second dust suction pipe and the third dust suction pipe can be operated to cover the rotor-spun fabric production equipment and the surrounding environment, forming a three-dimensional dust suction network.

[0019] S2. Subsequently, after the centrifugal fan is started, a negative pressure is formed in the exhaust chamber, and a negative pressure is instantaneously formed inside the cyclone separator through the sealed pipeline, and then conducted to the treatment chamber, so that the three dust suction pipes generate suction synchronously.

[0020] When the dust-containing air flow enters the dust suction pipe, the air flow drives the rotating main shaft to drive the eddy current blade to rotate, and the cotton knots are broken into particles. The blade thicknesses of the eddy current blades inside different dust suction pipes are different, so as to adapt to different crushing environments.

[0021] S3. Subsequently, the crushed impurities rise with the air flow to the top of the treatment chamber. At this time, the sealed opening and closing assembly remains stable. The electromagnet is energized to press down the sealing strip, and the dynamic filter screen is kept stationary in cooperation with the sealing frame to intercept fabric debris such as cotton knots.

[0022] Subsequently, the air flow containing dust passes through the dynamic filter screen and is guided into the cyclone separator for centrifugal dust removal through the side wall of the sealing frame. The generated dust enters the collection box inside the cyclone separator, and the air flow is discharged through the exhaust end of the cyclone separator and enters the exhaust chamber through the sealed pipeline.

[0023] S4. When the equipment operates for a certain period of time, the cotton knots and the like stored on the top of the dynamic filter screen block the air intake. At this time, the dynamic gradient filtration system operates, and the electromagnet changes the direction of the current. In actual use, a spring can be used instead. At this time, the sealing strip is lifted into the installation groove, so that the passage between the treatment chamber and the recovery chamber is opened.

[0024] Meanwhile, the drive motor starts to drive the synchronous shaft to rotate. At this time, the synchronous pulley on the synchronous shaft rotates accordingly, and the synchronous belt starts to drive the dynamic filter screen to operate through the teeth. The dynamic filter screen with neps continuously enters the inside of the recovery cavity and falls inside the recovery cavity;

[0025] Meanwhile, during the above process, the electromagnetic control valve opens, and part of the air flow in the exhaust cavity enters the air duct in the synchronous shaft through the return pipe and sprays out in a spiral shape from the rotating air holes. The air holes rotate with the shaft to form a dynamic air flow network, covering the fan-shaped area on the surface of the dynamic filter screen, blowing off the attached particulate neps. At the same time, the incoming air flow is discharged through the one-way exhaust valve on the inspection plate;

[0026] S5. After the dynamic filter screen moves a certain distance, the drive motor stops rotating, and the electromagnet presses down on the sealing strip again to achieve sealing. Meanwhile, the electromagnetic control valve closes. After the treatment cavity is resealed, the centrifugal fan sucks to restore the negative pressure in the cavity, and the dust suction pipe restores the maximum suction force;

[0027] S6. When the equipment finishes the operation, it shuts down in sequence, and then the power supply of each equipment is cut off for maintenance. The user can expose the inside of the recovery cavity by removing the inspection plate, so that the inside can be processed.

[0028] Compared with the prior art, the advantages of the present invention are as follows:

[0029] In the present invention, the core advantage of the cleaning equipment for air-jet spun fabric production lies in its highly intelligent three-pipe collaborative cleaning system and dynamic self-cleaning filter screen design, which realizes efficient, continuous, and maintenance-free cleaning operations. The equipment adopts three groups of adjustable dust suction pipes to form a three-dimensional cleaning network, in which precise positioning is achieved through the stepless adjustment component, and it is specifically used to adsorb scattered fibers to ensure full coverage of the middle and upper regions of the equipment;

[0030] All three groups of dust suction pipes are equipped with air-driven crushing components inside. The eddy current blades of the air-driven crushing components adopt a gradient blade thickness design, and cooperate with shark tooth-shaped protrusions to form a three-stage crushing system, which can not only efficiently process large particle neps but also avoid pipeline blockage;

[0031] When the neps accumulate, the dynamic filter screen system can automatically release the seal of the opening and closing component, and the drive motor drives the filter screen to translate, and cooperate with the auxiliary blowing of the return air flow to realize self-cleaning without stopping the machine, completely solving the pain point that traditional equipment needs to stop for cleaning. The whole set of system ensures long-term stable operation through secondary dust removal by the cyclone separator and closed-loop air flow control, and significantly improves the continuity and cleaning efficiency of air-jet spun fabric production.

[0044] The sealing opening and closing component 708 includes an installation groove 7081. The installation groove 7081 is opened on the inner wall of the processing chamber 6.

[0046] The air-driven crushing component 12 includes a connecting flange 1201 which is detachably connected to the nozzle position of the dust suction pipe. A rotating main shaft 1202 is rotatably installed on the connecting flange 1201, and evenly distributed eddy current blades 1203 are installed on the side of the rotating main shaft 1202;

[0047] The rotating main shaft 1202 is in a hollow state, and micron-level shark tooth-shaped protrusions 1204 are arranged on the surface of the eddy current blade 1203;

[0048] The stepless adjustment component 11 includes a folding sleeve 1101. Both ends of the folding sleeve 1101 are installed on the dust suction pipe through flanges. A threaded sleeve 1102 is installed at the top of the folding sleeve 1101, and a threaded shaft 1103 is rotatably connected to the bottom end of the folding sleeve 1101. The top end of the threaded shaft 1103 is located inside the threaded sleeve 1102 and is threadedly connected to the inner wall of the threaded sleeve 1102;

[0049] Limit sleeves 1104 and sliding rods 1105 are respectively installed at the top end and the bottom end of the folding sleeve 1101, and the limit sleeve 1104 is sleeved on the sliding rod 1105;

[0050] Maintenance plates 14 are detachably connected to the front and back of the cleaner housing 1. The maintenance plates 14 shield the recovery chamber 707, and a one-way exhaust valve 15 is installed on the maintenance plates 14;

[0051] The blade thicknesses of the multiple eddy current blades 1203 in the first dust suction pipe 8, the second dust suction pipe 9 and the third dust suction pipe 10 gradually become smaller in sequence. The blade thickness of the eddy current blade 1203 in the second dust suction pipe 9 is greater than the blade thicknesses of the eddy current blades 1203 in the second dust suction pipe 9 and the third dust suction pipe 10.

[0052] A cleaning method for a cleaning device used in the production of air-jet spun fabrics includes the following steps:

[0053] S1. The cleaner housing 1 moves along the track to a designated position on the production line. The first dust suction pipe 8 is automatically lowered to a certain distance from the ground through the folding sleeve 1101. The threaded sleeve 1102 of the stepless adjustment component 11 rotates synchronously, driving the limit sleeve 1104 to lock the height. At the same time, the stepless adjustment components 11 in the second dust suction pipe 9 and the third dust suction pipe 10 can be operated to cover the air-jet spun fabric production equipment and the surrounding environment, forming a three-dimensional dust suction network;

[0054] S2. Subsequently, after the centrifugal fan 4 is started, a negative pressure is formed in the exhaust chamber 3, and a negative pressure is instantaneously formed inside the cyclone separator 2 through the sealed pipe 5, and then conducted to the treatment chamber 6, so that the three groups of dust suction pipes generate suction force synchronously;

[0055] During the above process, the first dust suction pipe 8 is automatically lowered to a suitable height from the ground through the stepless adjustment assembly 11. Its folding sleeve 1101 adjusts the height through the meshing of the threaded sleeve 1102 and the threaded shaft 1103, and the position is locked by the limit sleeve 1104 to ensure stable adsorption of fiber debris scattered on the ground. The second dust suction pipe 9 and the third dust suction pipe 10 correspond to different positions of the production equipment to form a three-dimensional dust suction network covering the middle and upper regions of the equipment. An air-driven crushing assembly 12 is equipped inside all three groups of dust suction pipes. Among them, the rotating main shaft 1202 drives the eddy current blade 1203 to rotate at high speed under the drive of air flow, and the blade edge thickness gradient decreases, ensuring that large cotton knots are decomposed into debris in the first-stage crushing, and the subsequent pipes further refine the treatment. The shark-tooth-shaped protrusions 1204 on the surface of the eddy current blade 1203 enhance the fiber pulling and crushing effect;

[0056] When the dust-containing air flow enters the dust suction pipe, the air flow drives the rotating main shaft 1202 to drive the eddy current blade 1203 to rotate, and the cotton knots are broken into particles. The edge thicknesses of the eddy current blades 1203 inside different dust suction pipes are different, so as to adapt to different crushing environments;

[0057] S3. Subsequently, the crushed impurities rise with the air flow to the top of the treatment chamber 6. At this time, the seal opening and closing assembly 708 remains stable. The electromagnet 7083 is energized to press down the sealing strip 7082, and the dynamic filter screen 706 is kept stationary in cooperation with the sealing frame 701 to intercept fabric debris such as cotton knots.

[0058] Subsequently, the air flow containing dust passes through the dynamic filter screen 706 and is guided by the side wall of the sealing frame 701 into the cyclone separator 2 for centrifugal dust removal. The generated dust enters the collection box inside the cyclone separator 2, and the air flow is discharged through the exhaust end of the cyclone separator 2 and enters the exhaust chamber 3 through the sealed pipe 5;

[0059] S4. When the equipment has been running for a certain period of time, the cotton knots and the like stored on the top of the dynamic filter screen 706 block the air intake. At this time, the dynamic gradient filtration system 7 operates, and the electromagnet 7083 changes the direction of the current. In actual use, a spring can be used instead. At this time, the sealing strip 7082 is lifted into the installation groove 7081, so that the passage between the treatment chamber 6 and the recovery chamber 707 is opened;

[0060] At the same time, the drive motor 702 is started to drive the synchronous shaft 703 to rotate. At this time, the synchronous pulley 704 on the synchronous shaft 703 rotates accordingly, and the synchronous belt 705 starts to drive the dynamic filter screen 706 to rotate through the teeth. The dynamic filter screen 706 with the cotton knot part continuously enters the inside of the recovery chamber 707 and falls inside the recovery chamber 707;

[0061] Meanwhile, during the above process, the electro-control valve 7092 is opened, and a part of the air flow in the exhaust chamber 3 enters the air duct in the synchronous shaft 703 through the return pipe 7091, and is ejected in a spiral shape from the rotating air holes 7093. The air holes 7093 rotate with the shaft to form a dynamic air flow network, covering the fan-shaped area on the surface of the dynamic filter screen 706, blowing off the attached particulate cotton knots, and at the same time, the incoming air flow is discharged through the one-way exhaust valve 15 on the maintenance panel 14;

[0062] S5. After the dynamic filter screen 706 moves a certain distance, the driving motor 702 stops rotating, and the electromagnet 7083 presses down on the sealing strip 7082 again to achieve sealing. Meanwhile, the electro-control valve 7092 is closed. After the treatment chamber 6 is resealed, the centrifugal fan 4 sucks to restore the negative pressure in the chamber, and the dust suction pipe restores the maximum suction force;

[0063] S6. When the equipment finishes the operation, it shuts down in sequence, and then the power supply of each equipment is cut off for maintenance. The user can expose the inside of the recovery chamber 707 by removing the maintenance panel 14, so that the inside can be processed.

[0064] In the present invention, the core advantage of the cleaning equipment for air-jet spun fabric production lies in its highly intelligent three-pipe collaborative cleaning system and dynamic self-cleaning filter screen design, which realizes efficient, continuous, and maintenance-free cleaning operations. The equipment adopts three groups of adjustable dust suction pipes to form a three-dimensional cleaning network, and the precise positioning is realized through the stepless adjustment component 11, which is specifically used to adsorb scattered fibers to ensure full coverage of the middle and upper regions of the equipment;

[0065] Air-driven crushing components 12 are equipped inside all three groups of dust suction pipes. The eddy current blades 1203 of the air-driven crushing components 12 adopt a gradient blade thickness design, and cooperate with the shark tooth-shaped protrusions 1204 to form a three-stage crushing system, which can not only efficiently process large cotton knots but also avoid pipeline blockage;

[0066] When cotton knots accumulate, the dynamic filter screen 706 system can automatically release the seal of the sealing and opening / closing component 708. The driving motor 702 drives the filter screen to translate, and cooperates with the return air flow for auxiliary blowing to realize self-cleaning without shutting down, completely solving the pain point that traditional equipment needs to shut down for cleaning. The whole set of system ensures long-term stable operation through the secondary dust removal of the cyclone separator 2 and the closed-loop air flow control, and significantly improves the continuity and cleaning efficiency of air-jet spun fabric production.

[0067] Please refer to Figure 2 , in which: a wind guide cover 13 is installed on the inner wall of the exhaust chamber 3, and the return pipe 7091 is located inside the wind guide cover 13.

[0068] In the present invention, the setting of the wind guide cover 13 can improve the air supply efficiency of the return pipe 7091, thereby realizing the rapid return of the air flow and improving the blowing efficiency of the attached cotton knots.

[0069] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.

8. A cleaning method for a cleaning device used in the production of rotor spun fabrics according to any one of claims 1-7, characterized in that, Including the following steps: S1. The cleaner housing (1) moves along the track to a specified position on the production line. The first dust suction pipe (8) is automatically lowered to a certain distance from the ground through the folding sleeve (1101). The threaded sleeve (1102) of the stepless adjustment component (11) rotates synchronously, driving the limit sleeve (1104) to lock the height. At the same time, the stepless adjustment components (11) in the second dust suction pipe (9) and the third dust suction pipe (10) can be operated to cover the air-jet spinning fabric production equipment and the surrounding environment, forming a three-dimensional dust suction network. S2. Subsequently, after the centrifugal fan (4) starts, a negative pressure is formed in the exhaust chamber (3). A negative pressure is instantaneously formed inside the cyclone separator (2) through the sealing pipeline (5), and then conducted to the treatment chamber (6), causing the three dust suction pipes to generate suction synchronously; When the dusty airflow enters the dust suction pipe, the airflow drives the rotating main shaft (1202) to drive the eddy current blade (1203) to rotate, and the neps are broken into particles. The blade thicknesses of the eddy current blades (1203) inside different dust suction pipes are different, so as to adapt to different crushing environments; S3. Subsequently, the crushed impurities rise with the airflow to the top of the treatment chamber (6). At this time, the sealing opening and closing assembly (708) remains stable. The electromagnet (7083) is energized to press down the sealing strip (7082), and cooperate with the sealing frame (701) to make the dynamic filter screen (706) in a static state, so as to intercept fabric debris such as neps; Subsequently, the airflow containing dust passes through the dynamic filter screen (706), is guided by the side wall of the sealing frame (701) and enters the cyclone separator (2) for centrifugal dust removal. The generated dust enters the collection box inside the cyclone separator (2), and the airflow is discharged through the exhaust end of the cyclone separator (2), and enters the exhaust chamber (3) through the sealing pipeline (5) and is discharged; S4. When the equipment runs for a certain period of time, the neps and the like stored on the top of the dynamic filter screen (706) block the air intake. At this time, the dynamic gradient filtration system (7) operates, and the electromagnet (7083) changes the direction of the current. In actual use, a spring can be used instead. At this time, the sealing strip (7082) is lifted into the installation groove (7081) inside, so that the passage between the treatment chamber (6) and the recovery chamber (707) is opened; At the same time, the drive motor (702) starts to drive the synchronous shaft (703) to rotate. At this time, the synchronous pulley (704) on the synchronous shaft (703) rotates accordingly, and the synchronous belt (705) starts to drive the dynamic filter screen (706) to rotate through the teeth. The part of the dynamic filter screen (706) with neps continuously enters the inside of the recovery chamber (707) and falls inside the recovery chamber (707); At the same time, during the above process, the electric control valve (7092) is opened. Part of the airflow in the exhaust chamber (3) enters the air duct in the synchronous shaft (703) through the return pipe (7091), and is sprayed out in a spiral shape from the rotating air holes (7093). The air holes (7093) rotate with the shaft to form a dynamic airflow network, covering the fan-shaped area on the surface of the dynamic filter screen (706), blowing off the attached particulate neps, and at the same time, the entering airflow is discharged through the one-way exhaust valve (15) on the inspection plate (14); S5. After the dynamic filter screen (706) moves a certain distance, the drive motor (702) stops rotating, and the electromagnet (7083) presses down the sealing strip (7082) again to achieve sealing. At the same time, the electric control valve (7092) is closed. After the treatment chamber (6) is resealed, the centrifugal fan (4) sucks to restore the negative pressure in the cavity, and the dust suction pipe restores the maximum suction; S6. When the equipment finishes the operation, it shuts down in sequence, and then powers off and repairs each equipment. The user can expose the inside of the recovery chamber (707) by removing the inspection plate 14, so that the inside can be processed.
