Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a waste removal device for the yarn separating port of a rotor spinning machine. Background Technology

[0002] Existing rotor spinning machines are generally equipped with a waste removal device, which includes a waste removal channel, a make-up air channel, and a waste removal pipe inside the spinning box 9. The impurity inlet end of the waste removal channel of the spinning box is set on the cavity wall of the combing chamber and communicates with the combing chamber. The impurity outlet end of the waste removal channel of the spinning box is connected to the waste removal pipe. The impurities are separated and thrown out under the centrifugal force of the high-speed rotating combing roller. With the help of the negative pressure attraction of the make-up air channel, they are discharged into the impurity box of the machine through the waste removal channel and the waste removal pipe.

[0003] However, due to changes in the channel condition caused by long-term operation or insufficient negative pressure for impurity removal, impurities can easily stick to the sleeve of the impurity removal device, causing impurities to enter the rotor along with the cotton fibers, resulting in a decrease in yarn quality. In severe cases, it can even lead to blockage of the impurity removal device and cause yarn breakage.

[0004] Therefore, it is necessary to provide a waste removal device for the yarn separating port of a rotor spinning machine to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a waste removal device for the yarn separating port of a rotor spinning machine, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a waste removal device for the yarn separating port of a rotor spinning machine, comprising a spinning box body, a waste removal pipe installed on the outer surface of the spinning box body, a fixing rod provided at one end of the inner wall of the waste removal pipe, a connecting ring provided on the surface of the fixing rod, a threaded hole penetrating the surface of the connecting ring, a threaded column spirally connected inside the threaded hole, a driving rod provided at one end of the threaded column, a sleeve movably mounted on the outer surface of the driving rod via a sealed bearing, a cleaning rod provided on the outer surface of the sleeve via a connecting rod, a brush provided on the surface of the cleaning rod, the brush contacting the inner wall of the waste removal pipe, and an impeller provided on the circumferential side of the sleeve. The combined use of a waste pipe, a fixed rod, a connecting ring, a threaded hole, a drive rod, a threaded column, a sleeve, an impeller, a cleaning rod, and a brush facilitates the cleaning of impurities from the inner wall of the waste pipe and the outlet of the waste discharge channel. During operation, the impeller drives the sleeve to rotate under the gas flow rate. The sleeve then drives the cleaning rod to rotate via the fixed rod. The rotation of the cleaning rod causes the brush to clean the impurities from the waste pipe and the outlet of the waste discharge channel. The cleaned impurities are discharged with the gas, and some are adsorbed on the surface of the brush. Finally, the drive rod removes the cleaning rod from the waste pipe, and the impurities on the brush surface are cleaned. This method is simple to operate and facilitates the discharge of impurities.

[0007] Preferably, the spinning box body is provided with a diversion cavity inside, and the inner wall of the diversion cavity is provided with a waste discharge channel, which is connected to the waste discharge pipe. By providing the waste discharge channel, it is convenient to discharge impurities.

[0008] Preferably, the outer surface of the spinning box body is provided with a make-up air channel, and the make-up air channel is connected to the impurity discharge pipe through a pressure regulating cavity. The pressure regulating cavity has a trapezoidal cross-section. By setting the pressure regulating cavity, the diameter of the outlet of the pressure regulating cavity is smaller than the inner diameter of the make-up air channel. As a result, when the airflow inside the make-up air channel is discharged through the pressure regulating cavity, the air pressure increases, thereby increasing the gas flow rate and accelerating the discharge efficiency of impurities.

[0009] Preferably, a fan is installed on the outer surface of the spinning box body, and the output end of the fan is connected to the air supply channel. By setting up the fan, it is convenient to provide airflow to the air supply channel.

[0010] Preferably, the surface of the connecting rod is provided with a tapered rod. By providing the tapered rod, it is easy to divert the airflow and avoid obstructing the gas.

[0011] Preferably, a fixing ring is provided at one end of the discharge pipe, and a fixing hole is provided on the surface of the fixing ring. The fixing ring is fixedly connected to the spinning box body through the fixing hole by a fastener. By providing a fixing ring, it is convenient to fix the discharge pipe with fasteners.

[0012] Preferably, a controller is installed on the outer surface of the spinning box body, which facilitates the control of the electrical components inside the device body.

[0013] Compared with related technologies, the impurity removal device for the yarn separating port of the rotor spinning machine provided by this utility model has the following beneficial effects: Compared with existing technologies, the impurity removal device for the yarn separating port of a rotor spinning machine, through the coordinated use of an impurity removal pipe, a fixed rod, a connecting ring, a threaded hole, a drive rod, a threaded column, a sleeve, an impeller, a cleaning rod, and a brush, facilitates the cleaning of impurities on the inner wall of the impurity removal pipe and at the outlet of the impurity removal channel. During operation, under the gas flow rate, the impeller drives the sleeve to rotate, and then the sleeve drives the cleaning rod to rotate via the fixed rod. Under the rotation of the cleaning rod, the brush cleans the impurities at the outlet of the impurity removal pipe and the outlet of the impurity removal channel. The cleaned impurities are discharged with the gas, and some are adsorbed on the surface of the brush. Finally, the drive rod removes the cleaning rod from the impurity removal pipe, and then the impurities on the brush surface are cleaned. This method is simple to operate and facilitates the removal of impurities. By setting up a pressure regulating chamber, the diameter of the outlet of the pressure regulating chamber is smaller than the inner diameter of the air supply channel. As the airflow inside the air supply channel is discharged through the pressure regulating chamber, the air pressure increases, thereby increasing the gas flow rate and accelerating the removal efficiency of impurities.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] First Embodiment Please refer to the following: Figure 1-4A waste removal device for the yarn separating port of a rotor spinning machine includes a spinning box body 1. A waste removal pipe 4 is installed on the outer surface of the spinning box body 1. A fixing rod 17 is provided at one end of the inner wall of the waste removal pipe 4. A connecting ring 10 is provided on the surface of the fixing rod 17. A threaded hole 11 is opened through the surface of the connecting ring 10. A threaded column 14 is spirally connected inside the threaded hole 11. A drive rod 5 is provided at one end of the threaded column 14. A sleeve 18 is movably installed on the outer surface of the drive rod 5 through a sealed bearing 19. A cleaning rod 15 is provided on the outer surface of the sleeve 18 through a connecting rod 6. A brush 16 is provided on the surface of the cleaning rod 15 and contacts the inner wall of the waste removal pipe 4. An impeller 20 is provided on the circumferential side of the sleeve 18. The device is constructed by setting up the waste removal pipe 4 and the fixing rod 17. The combined use of the connecting ring 10, threaded hole 11, drive rod 5, threaded column 14, sleeve 18, impeller 20, cleaning rod 15, and brush 16 facilitates the cleaning of impurities on the inner wall of the discharge pipe 4 and at the outlet of the discharge channel 3. During operation, under the flow rate of gas, the impeller 20 drives the sleeve 18 to rotate. Then, the sleeve 18 drives the cleaning rod 15 to rotate via the fixing rod 17. Under the rotation of the cleaning rod 15, the brush 16 cleans the impurities at the outlet of the discharge pipe 4 and the discharge channel 3. The cleaned impurities are discharged with the gas, and some are adsorbed on the surface of the brush 16. Finally, the drive rod 5 removes the cleaning rod 15 from the discharge pipe 4, and then the impurities on the surface of the brush 16 are cleaned. This method is simple to operate and facilitates the discharge of impurities.

[0019] The working principle of the impurity removal device for the yarn separating port of the rotor spinning machine provided by this utility model is as follows: The impurity removal device at the yarn separating port of the rotor spinning machine operates by rotating the sleeve 18 via the impeller 20 under the gas flow rate. The sleeve 18 then rotates the cleaning rod 15 via the fixed rod 17. Under the rotation of the cleaning rod 15, the brush 16 cleans the impurities at the outlet of the impurity removal pipe 4 and the impurity removal channel 3. The cleaned impurities are discharged with the gas, and some are adsorbed on the surface of the brush 16. Finally, the cleaning rod 15 is removed from the impurity removal pipe 4 by the drive rod 5, and the impurities on the surface of the brush 16 are cleaned. This method is simple to operate and facilitates the discharge of impurities. By setting a pressure regulating chamber 7, the diameter of the air outlet of the pressure regulating chamber 7 is smaller than the inner diameter of the air supply channel 8. When the airflow inside the air supply channel 8 is discharged through the pressure regulating chamber 7, the air pressure increases, thereby increasing the gas flow rate and accelerating the discharge efficiency of impurities.

[0020] Compared with related technologies, the impurity removal device for the yarn separating port of the rotor spinning machine provided by this utility model has the following beneficial effects: The impurity removal device at the yarn separating port of a rotor spinning machine, through the coordinated use of an impurity removal pipe 4, a fixed rod 17, a connecting ring 10, a threaded hole 11, a drive rod 5, a threaded column 14, a sleeve 18, an impeller 20, a cleaning rod 15, and a brush 16, facilitates the cleaning of impurities from the inner wall of the impurity removal pipe 4 and the outlet of the impurity removal channel 3. During operation, under the gas flow rate, the impeller 20 drives the sleeve 18 to rotate, and then the sleeve 18 drives the cleaning rod 15 to rotate via the fixed rod 17. The rotation of the cleaning rod 15 causes the brush 16 to clean the impurity removal pipe 4. The impurities at the discharge port of the impurity discharge channel 3 are cleaned. The cleaned impurities are discharged with the gas, and some of them are adsorbed on the surface of the brush 16. Finally, the cleaning rod 15 is moved out of the impurity discharge pipe 4 by the drive rod 5, and then the impurities on the surface of the brush 16 are cleaned. This method is simple to operate and facilitates the discharge of impurities. By setting the pressure regulating chamber 7, the diameter of the air outlet of the pressure regulating chamber 7 is smaller than the inner diameter of the air supply channel 8. As a result, when the airflow inside the air supply channel 8 is discharged through the pressure regulating chamber 7, the air pressure increases, thereby increasing the gas flow rate and accelerating the discharge efficiency of impurities.
