[0006] A circular knitting machine that reduces the flying of lint provided by this application adopts the following technical solution:

[0007] A circular knitting machine that reduces the flying of lint, including a circular knitting machine main body, a fixed frame is provided on the circular knitting machine main body, a rotating shaft is rotatably connected to the fixed frame, a fan is provided at the upper end of the rotating shaft, a moving frame that moves along the circumferential direction of the circular knitting machine main body is provided on the circular knitting machine main body, a driving member for driving the moving frame to move is provided on the circular knitting machine main body, a suction hood with an opening facing the fan is provided on the moving frame, the suction hood is connected to a collecting box through a suction pipe, a vacuum pump is provided on the collecting box, an atomizing nozzle is provided on the inner side wall of the suction hood, the atomizing nozzle is connected to a water tank through a water inlet pipe, and a water pump is provided on the water inlet pipe.

[0008] By adopting the above technical solution, when the circular knitting machine works, the turntable drives the fan to rotate, so that the fan can blow the lint in all directions on the circular knitting machine. The driving member drives the moving frame to move around the circular knitting machine, and the moving frame drives the suction hood to always be aligned with the fan. The vacuum pump makes the inside of the suction hood in a negative pressure state, sucking away the lint blown by the fan. The water pump transports the water in the water tank to the atomizing nozzle through the water inlet pipe and sprays it out, thereby wetting the lint and reducing the flying of the lint.

[0009] Optionally, a horizontal filter screen is provided in the collection box. The suction pipe is located above the filter screen, and the vacuum pump is located below the filter screen.

[0010] By adopting the above technical solution, the filter screen intercepts the lint sucked into the collection box, reducing the entry of lint into the vacuum pump and playing a role in protecting the vacuum pump.

[0011] Optionally, the lower end of the collection box is connected to the water tank through a connecting pipe.

[0012] By adopting the above technical solution, the water in the collection box flows into the water tank through the connecting pipe, playing a role in recycling water.

[0013] Optionally, the lower end of the collection box is arranged in an inclined plane. The vacuum pump is arranged at the highest point of the inclined plane, and the connecting pipe is arranged at the lowest point of the inclined plane.

[0014] By adopting the above technical solution, the inclined plane at the lower end of the collection box plays a role in gathering water, facilitating the water to flow into the connecting pipe.

[0015] Optionally, a connecting ring is coaxially arranged on the suction pipe. A plurality of clamping grooves are formed on the connecting ring, and a plurality of clamping rods are arranged on the suction hood. The plurality of clamping rods correspond to the plurality of clamping grooves one by one and are clamped into the corresponding clamping grooves.

The clamping block and the clamping rod are connected by a torsion spring, and the torsion spring is used to maintain the state where the clamping block is perpendicular to the clamping rod.

[0018] By adopting the above technical solution, when installing the suction hood, the clamping block is rotated to a state where it coincides with the clamping rod, which is convenient for passing through the clamping groove. After the installation is completed, the torsion spring drives the clamping block to rotate to a state where it is perpendicular to the clamping rod, so that the clamping block is clamped with the connecting ring, reducing the occurrence of the suction hood falling off.

[0019] Optionally, the driving member includes an external gear ring, a gear, and a driving motor. The external gear ring is sleeved on the main body of the circular knitting machine. The gear is rotatably connected to the moving frame and meshed with the external gear ring. The transmission shaft of the driving motor is coaxially connected to the gear.

[0020] By adopting the above technical solution, the motor drives the gear to rotate. The meshing of the gear and the external gear ring causes the gear to drive the connecting frame to move around the external gear ring when rotating.

[0021] Optionally, an annular groove coaxial with the external gear ring is formed at the upper end of the external gear ring. A roller is provided on the moving frame, and the roller is in rolling cooperation with the annular groove.

[0022] By adopting the above technical solution, the cooperation between the roller and the annular groove reduces the friction between the moving frame and the external gear ring, making it more convenient for the moving frame to move on the external gear ring.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The water pump transports the water in the water tank to the atomizing nozzle through the water inlet pipe and sprays it out, thereby wetting the wool dust and reducing the flying of the wool dust.

[0025] 2. A plurality of clamping rods are inserted into the corresponding clamping grooves, so that the suction hood is fixed on the connecting ring. This installation method is relatively convenient for disassembly and assembly.

[0026] 3. When installing the suction hood, the clamping block is rotated to a state where it coincides with the clamping rod, which is convenient for passing through the clamping groove. After the installation is completed, the torsion spring drives the clamping block to rotate to a state perpendicular to the clamping rod, so that the clamping block is engaged with the connecting ring, reducing the occurrence of the suction hood falling off.

[0033] The following further elaborates on this application Figures 1-5 in conjunction with the attached drawings.

[0034] An embodiment of this application discloses a circular knitting machine for reducing the flying of lint. Refer to Figure 1 , a circular knitting machine for reducing the flying of lint includes a main body 1 of the circular knitting machine. A fixed frame 2 is installed on the main body 1 of the circular knitting machine. A vertical rotating shaft 21 is rotatably connected to the fixed frame 2. The rotating shaft 21 is driven to rotate by a motor. A fan 22 is installed at the upper end of the rotating shaft 21, so that the fan 22 can blow the lint in all directions.

[0035] Refer to Figure 1 and Figure 2 , a moving frame 3 that moves circumferentially along the main body 1 of the circular knitting machine is slidably connected to the main body 1 of the circular knitting machine. A driving member 4 for driving the moving frame 3 to move is installed on the main body 1 of the circular knitting machine. The driving member 4 includes an outer tooth ring 41, a gear 42 and a driving motor 43. The outer tooth ring 41 is coaxially fixed to the main body 1 of the circular knitting machine. The gear 42 is rotatably connected to the moving frame 3 and is engaged with the outer tooth ring 41. The driving motor 43 is fixed to the moving frame 3. The transmission shaft of the driving motor 43 is coaxially connected to the gear 42. When the gear 42 rotates, it drives the moving frame 3 to move through meshing with the outer tooth ring 41. An annular groove 411 is coaxially opened at the upper end of the outer tooth ring 41. A roller 412 is rotatably connected to the moving frame 3. The roller 412 is in rolling cooperation with the annular groove 411, which plays a role in reducing friction.

[0036] Refer to Figure 2 and Figure 3, an air suction hood 31 with an opening facing the fan 22 is installed on the moving frame 3. One end of the air suction hood 31 far from the fan 22 is detachably connected to an air suction pipe 32. A connecting ring 321 is coaxially connected to the air suction pipe 32. Two clamping grooves are formed on the connecting ring 321. Two clamping rods 312 are fixed at one end of the air suction hood 31 close to the air suction pipe 32. The sizes and positions of the two clamping rods 312 respectively correspond to those of the two clamping grooves. One end of the clamping rod 312 far from the air suction hood 31 is rotatably connected to a clamping block 313. The clamping block 313 is connected to the clamping rod 312 through a torsion spring 314. The torsion spring 314 is used to maintain the state where the clamping block 313 is perpendicular to the clamping rod 312. When installing the air suction hood 31, the clamping block 313 is rotated to a state where it coincides with the clamping rod 312, which is convenient for passing through the clamping groove. After the installation is completed, the torsion spring 314 drives the clamping block 313 to rotate to a state where it is perpendicular to the clamping rod 312, so that the clamping block 313 is engaged with the connecting ring 321, reducing the occurrence of the air suction hood 31 falling off.

[0037] Refer to Figure 1 , Figure 2 and Figure 5 , one end of the air suction pipe 32 far from the air suction hood 31 is connected to a collection box 33. The collection box 33 is installed on the moving frame 3. The lower end of the collection box 33 is arranged in an inclined plane. A horizontal filter screen 332 is installed inside the collection box 33. The air suction pipe 32 is located above the filter screen 332. A vacuum pump 331 is installed on the side wall of the collection box 33. The vacuum pump 331 is located below the filter screen 332 and at a high position on the inclined plane. The vacuum pump 331 creates a negative pressure in the collection box 33 and the air suction hood 31, thereby sucking away the lint blown off by the fan 22. The filter screen 332 is used to intercept the lint and reduce the lint from entering the vacuum pump 331.

[0038] Refer to Figure 2 , Figure 3 and Figure 4 , the lower end of the collection box 33 is connected to a connecting pipe 35. The connecting pipe 35 is located at a low position on the inclined plane. The other end of the connecting pipe 35 is connected to a water tank 34. The water tank 34 is installed on the moving frame 3. A water inlet pipe 341 is connected to the water tank 34. The other end of the water inlet pipe 341 is connected to the side wall of the air suction hood 31. An atomizing nozzle 311 is installed on the inner side wall of the air suction hood 31. The atomizing nozzle 311 is supplied with water through the water inlet pipe 341. When the atomizing nozzle 311 sprays water, the lint is wetted, thereby reducing the flying of the lint.

[0039] The implementation principle of a circular knitting machine for reducing lint flying in an embodiment of the present application is as follows: When the circular knitting machine is working, the fan 22 blows the lint on the main body 1 of the circular knitting machine, and the suction hood 31 generates negative pressure through the vacuum pump 331 to suck away the lint blown by the fan 22. When sucking away the lint, the water in the water tank 34 is sprayed out through the atomizing nozzle 311 to wet the lint and reduce the flying of the lint. The lint sucked into the collection box 33 is intercepted by the filter screen 332, and the water in the collection box 33 is drained to a lower place through the inclined plane and flows into the water tank 34 through the connecting pipe 35 for recycling, playing a role in saving water.

[0040] The above are all preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
