Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, specifically to a cotton cleaning mechanism for a spinning machine used in cotton yarn production. Background Technology

[0002] In the cotton yarn production process, the spinning machine is the key equipment for twisting and winding cotton yarn. As an important part of the spinning machine, the cotton cleaning mechanism has the main function of timely removing impurities such as cotton lint, short fibers, and dust generated during the cotton yarn production process, so as to ensure the quality of cotton yarn products, reduce equipment wear, and improve the workshop working environment.

[0003] To ensure filtration efficiency, filter components need to be cleaned or replaced regularly. However, in existing cotton cleaning mechanisms, filter components are mostly rigidly connected to the inner wall of the air duct using bolts and other fasteners, making disassembly and installation cumbersome and requiring significant manpower and time. Furthermore, during replacement, if the fan is not shut down, the negative pressure inside the air duct can cause airflow leakage, potentially backflowing unfiltered impurities into the production area; if the fan is shut down, the normal operation of the spinning machine will be interrupted, affecting production efficiency. Therefore, a new solution is needed to address this problem.

[0004] When the filter components are replaced or cleaned, the lack of an effective shielding structure and the direct connection between the inside of the duct and the outside will disrupt the original negative pressure environment, leading to a decrease in the dust collection capacity of the cotton cleaning mechanism, and even local airflow turbulence, which will affect the adsorption effect on cotton dust and thus reduce the quality of cotton cleaning. Utility Model Content

[0005] In view of the shortcomings and defects of the existing technology mentioned above, such as inconvenient component maintenance and poor airflow stability, the technology is intended to address these issues.

[0006] The cotton cleaning mechanism for a spinning machine used in cotton yarn production disclosed in this utility model includes a mounting plate. A duct and a mounting shell are provided on one side of the mounting plate. The duct is connected to the mounting shell. A fan is provided inside the mounting shell. A fixing frame is installed inside the duct. Fixing frames are provided between the fixing frame and the duct on both sides. A filter assembly is provided inside the fixing frame. A shielding assembly is provided at both ends of the fixing frame and the duct.

[0007] Furthermore, the filter assembly includes a metal mesh, a non-woven fabric mesh, and an activated carbon mesh, all of which are fixedly installed on the fixed frame and arranged sequentially from the end furthest from the mounting shell to the end closest to the mounting shell.

[0008] Furthermore, the shielding assembly includes baffles, and two baffles are symmetrically installed at both ends of the fixing frame. The baffles are rotatably connected to the fixing frame via drive shafts, and a transmission component is provided between the two drive shafts near the same fixing frame.

[0009] Furthermore, the transmission component includes a drive rod, which is rotatably mounted on the air duct. Worms are symmetrically arranged at both ends of the drive rod, with the helixes of the two worms in opposite directions. A worm wheel is meshed on one side of each of the two worms, and the worm wheel is mounted on the drive shaft. A drive handle is installed in the middle of the drive rod.

[0010] Furthermore, a protective shell is provided on the outer side of the worm and the worm wheel, and the protective shell is installed on the air duct.

[0011] Furthermore, the upper and lower ends of the fixing frame are both set in an "H" shape, the fixing frame is slidably disposed with the fixing frame, the upper and lower ends of the fixing frame are both provided with sealing rings, and a limit block is rotatably installed on the air duct, with one end of the limit block contacting the fixing frame.

[0012] Furthermore, the end of the baffle away from the fixed frame is inclined, and magnets are provided on the inclined surface of the baffle and the corresponding inner wall of the air duct.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a fixed frame that slides with the air duct and the fixed bracket, and achieves quick fixation through a limiting block. Compared with the traditional bolt fixing method, it greatly simplifies the disassembly and installation process of the filter component and reduces manpower and time consumption. At the same time, the shielding component can close the corresponding area inside the air duct when replacing the filter component. It can be operated without turning off the fan, avoiding production interruption caused by machine stoppage for component replacement, and taking into account both maintenance convenience and production efficiency.

[0015] 2. The filter assembly of this utility model adopts a three-layer structure of metal mesh, non-woven fabric mesh and activated carbon mesh, which achieves graded filtration of large particulate impurities, fine cotton fibers and odors from the outside to the inside, thereby improving the cotton cleaning and purification effect. In addition, the shielding component, through the cooperation of baffle and magnet, can effectively isolate the airflow inside and outside the air duct when the filter assembly is replaced, maintain a stable negative pressure environment inside the air duct, avoid backflow of impurities or a decrease in dust suction capacity, and ensure the consistency of cotton cleaning quality.

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0023] Please see Figure 1 The cotton cleaning mechanism for a spinning machine in cotton yarn production of this utility model includes a mounting plate 1. The mounting plate 1 is made of Q235 steel plate and the surface is galvanized to improve its rust resistance and adapt to the environment of the spinning workshop with many cotton fibers and low humidity. The mounting plate 1 is provided with mounting holes 17. Multiple mounting holes 17 are provided and evenly distributed on the edge of the mounting plate 1. The hole diameter is adapted to the standard bolts of the spinning machine frame to ensure that the overall structure does not shake after installation.

[0024] See Figure 1 , Figure 2 , Figure 4 As shown, a duct 2 and a mounting shell 3 are provided on one side of the mounting plate 1. The duct 2 is connected to the mounting shell 3. The duct 2 is made of galvanized steel pipe with a smooth inner wall to reduce airflow resistance. The connection between the duct 2 and the mounting shell 3 is sealed with a flange, and a rubber gasket is installed between the flanges to prevent negative pressure leakage. A fan is installed inside the mounting shell 3, and a fixing frame 6 is installed inside the duct 2. Fixing frames 4 are provided on both sides of the fixing frame 6 and between the fixing frame 6 and the duct 2. The upper and lower ends of the fixing frame 6 are both set as "H" shapes.

[0025] See Figure 2 , Figure 4 As shown, the fixed frame 4 and the fixed bracket 6 are slidably arranged. The upper and lower ends of the fixed frame 4 are provided with sealing rings 15. The sealing rings 15 are made of food-grade silicone and are embedded in the grooves at the upper and lower ends of the fixed frame 4 respectively. They fit tightly with the inner wall of the air duct 2 and the "H"-shaped groove of the fixed bracket 6 to prevent unfiltered airflow from leaking from the gaps. A limit block 14 is rotatably installed on the air duct 2. One end of the limit block 14 contacts the fixed frame 4. One end of the limit block 14 is connected to the air duct 2 through a damping shaft. The other end is covered with a rubber pad. After rotation, it can press the outer side of the fixed frame 4 to prevent the fixed frame 4 from shifting due to airflow vibration when the fan is working.

[0026] In this embodiment, a filter assembly 5 is provided inside the fixed frame 4. The filter assembly 5 includes a metal mesh 501, a non-woven fabric mesh 502, and an activated carbon mesh 503. The metal mesh 501, non-woven fabric mesh 502, and activated carbon mesh 503 are all fixedly installed on the fixed frame 4 and are arranged sequentially from the end away from the mounting shell 3 to the end close to the mounting shell 3. The metal mesh 501 is made of 304 stainless steel and can be repeatedly washed and reused. The non-woven fabric mesh 502 uses high-density meltblown non-woven fabric, which can effectively trap fine cotton fibers and dust. The activated carbon mesh 503 uses columnar activated carbon particles, which are wrapped and fixed by non-woven fabric to adsorb residual oil, odors, and microorganisms in the cotton fibers, improve the cleanliness of the exhaust airflow, and has a certain degree of elasticity, so that some of the attached cotton fibers can be cleaned by patting.

[0027] In this embodiment, the fixed frame 4 and the air duct 2 are provided with shielding components at both ends of the fixed frame 6. The shielding components include baffles 7. Two baffles 7 are symmetrically installed at both ends of the fixed frame 6. The baffles 7 are made of cold-rolled steel plates and coated with anti-rust paint. The end of the baffle 7 away from the fixed frame 6 is inclined. Magnets 16 are provided on the inclined surface of the baffle 7 and the corresponding inner wall of the air duct 2. The magnets 16 are neodymium iron boron strong magnets, which are embedded in the inclined surface of the baffle 7 and the corresponding grooves on the inner wall of the air duct 2, respectively, and have opposite polarities. Together with the contact surface between the baffle 7 and the inner wall of the air duct 2, a double seal is achieved to prevent unfiltered airflow from flowing.

[0028] See Figure 1 , Figure 2 , Figure 3As shown, an arc-shaped plate 18 is provided at the end of the fixed frame 6 away from the mounting shell 3. The arc-shaped plate 18 contacts one end of the baffle 7. The baffle 7 is rotatably connected to the fixed frame 6 through the drive shaft 8. A transmission component is provided between the two drive shafts 8 near the same fixed frame 4. The transmission component includes a drive rod 11, which is rotatably mounted on the air duct 2. Worms 10 are symmetrically arranged at both ends of the drive rod 11. The spiral directions of the two worms 10 are opposite. A worm wheel 9 is meshed on one side of each of the two worms 10. The worm wheel 9 is mounted on the drive shaft 8. The self-locking characteristics of the worm wheel 9 and the worm 10 can fix the baffle 7 in any position and prevent it from shifting due to vibration.

[0029] In this embodiment, a protective shell 13 is provided on the outer side of the worm gear 10 and the worm wheel 9. The protective shell 13 is installed on the air duct 2. The protective shell 13 is made of ABS plastic injection molding and is fixed to the outer wall of the air duct 2 by bolts. The inside is filled with grease to protect the worm gear 10 and the worm wheel 9 from dust and lubrication, and to extend the service life of the transmission components. A drive handle 12 is installed in the middle of the drive rod 11. The drive handle 12 is cylindrical and has a knurled surface, which makes it easy for the operator to grip and apply force.

[0030] The implementation principle is as follows: During normal cotton cleaning operation, the mounting plate 1 provides overall installation support and fixes the equipment in the preset position of the spinning machine. The fan inside the mounting shell 3 starts and generates negative pressure through the connected air duct 2, which sucks in impurities such as cotton lint, short fibers, and dust generated during the spinning machine production process. At this time, the shielding component is in the open state, and the baffles 7 at both ends of the fixing frame 6 are kept open by the drive shaft 8, so as not to block the airflow channel.

[0031] After the airflow carrying impurities enters the duct 2, it passes through the filter components 5 inside the fixed frame 4 in sequence. The metal mesh 501 first filters large particles of impurities, the non-woven fabric mesh 502 in the middle filters fine cotton fibers, and the activated carbon mesh 503 adsorbs odors and fine dust, thus achieving graded filtration. The purified airflow is then drawn in and discharged by the fan.

[0032] When the filter assembly 5 needs to be cleaned or replaced, there is no need to turn off the fan: the operator turns the drive handle 12 in the middle of the drive rod 11, the drive rod 11 drives the worm gear 10 with opposite spiral directions at both ends to rotate, the worm gear 10 meshes with the worm wheel 9 on the drive shaft 8, so that the two baffles 7 on both sides of the same fixed frame 4 rotate synchronously until the inclined end of the baffle 7 contacts the inner wall of the air duct 2, the magnet 16 of the baffle 7 and the inner wall of the air duct 2 attract each other, enhance the seal, and close the airflow channel corresponding to the fixed frame 4;

[0033] Rotate the limiting block 14 on the air duct 2 to disengage it from the fixed frame 4, and directly pull the fixed frame 4 and the inner filter assembly 5 out of the air duct 2 for cleaning or replacement; after cleaning the filter assembly 5 or replacing it with a new filter assembly 5, push the fixed frame 4 back into its original position along the slide between the air duct 2 and the fixed frame 6, and rotate the limiting block 14 to make it contact the fixed frame 4 to achieve the limiting and fixing of the fixed frame 4; the sealing rings 15 at the upper and lower ends of the fixed frame 4 can enhance the sealing performance with the air duct 2 and the fixed frame 6;

[0034] The reverse rotation of the drive handle 12, through the worm gear 10 and worm wheel 9, causes the baffle 7 to rotate in the opposite direction, opening the airflow channel, separating the magnet 16, restoring the shielding component to the open state, and allowing the filter component 5 to re-engage in the cotton cleaning and filtration work. The entire process does not require machine downtime, ensuring continuous production.

[0035] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
