Description

Technical Field

[0001] The utility model relates to the technical field of rotor spinning, in particular to a waste removing device for a spinning device of a rotor spinning machine. Background Technique

[0002] Rotor spinning is a spinning technique that uses a high-speed rotating rotor to agglomerate fibers and form yarn. It has the advantages of high spinning speed, simple equipment structure, strong adaptability, etc., so it is widely used in the textile industry. During the process of rotor spinning, a waste removing port and a waste removing pipe are added between the carding roller carding point and the conveying channel. By utilizing the different centrifugal forces generated by the mass differences between fibers and dust impurities, the dust impurities are thrown out of the waste removing port. To enhance the waste removing effect, a guide plate, a fixed air supply port, an adjustable air supply valve, etc. are also arranged around the waste removing port. There are two types of waste removing devices: fixed type and adjustable type. For a rotor with a waste removing device, the dust accumulation in the cup is reduced, the yarn quality is good and stable, and the breakage is also less.

[0003] At present, during the process of removing dust impurities through the waste removing pipe by the spinning device of a rotor spinning machine, the dust impurities are easily adhered to the inner wall of the waste removing pipe, which easily causes the waste removing pipe to be blocked. Therefore, we propose a waste removing device for a spinning device of a rotor spinning machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a waste removing device for a spinning device of a rotor spinning machine, which has the advantages of being able to avoid the adhesion of dust impurities to the inner wall of the waste removing pipe main body during the process of removing dust impurities through the waste removing pipe main body by the spinning device of the rotor spinning machine, thereby avoiding the blockage phenomenon, and at the same time improving the dust removal efficiency, and solves the problem that during the process of removing dust impurities through the waste removing pipe by the current spinning device of the rotor spinning machine, the dust impurities are easily adhered to the inner wall of the waste removing pipe, which easily causes the waste removing pipe to be blocked.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A waste removing device for a spinning device of a rotor spinning machine, including a waste removing pipe main body and a sealing sleeve. The outer surface of the waste removing pipe main body is fixedly installed with a sealing sleeve. The outer surface of the sealing sleeve is fixedly connected with an air inlet pipe. A plurality of inclined air holes are arranged on the outer surface of the waste removing pipe main body.

[0006] Preferably, the end of the air inlet pipe is fixedly connected with an air filter. Before the air flow enters the inside of the sealing sleeve, dust impurities are filtered by the air filter to avoid blocking the inclined air holes.

[0007] Preferably, a flow equalizing mesh plate is fixedly installed inside the sealing sleeve. The flow equalizing mesh plate can make the air flow inside the sealing sleeve evenly enter the inclined air holes, so that the air flow distribution inside the waste removing pipe main body is uniform.

[0008] Preferably, the included angle α between the air outlet direction of the inclined air holes and the axis of the dust discharge pipe body satisfies 15° ≤ α ≤ 60°. Since the air outlet direction of the inclined air holes forms an acute angle with the dust discharge direction, it is beneficial to the discharge of dust.

[0009] Preferably, a sound-absorbing sleeve is fixedly sleeved on the outer surface of the sealing sleeve. The sound-absorbing sleeve absorbs the airflow noise inside the dust discharge pipe body, thereby reducing the noise.

[0010] Preferably, a sound-insulating sleeve is fixedly sleeved on the outer surface of the sound-absorbing sleeve. During the process of the dust discharge pipe body discharging dust, the sound-insulating sleeve can isolate the airflow noise.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By providing the dust discharge pipe body, the sealing sleeve, the air inlet pipe and the inclined air holes, the present utility model can avoid dust adhering to the inner wall of the dust discharge pipe body during the process of the spinneret of the rotor spinning machine discharging dust through the dust discharge pipe body, thereby avoiding blockage, and at the same time improving the dust discharge efficiency. The air flow enters the inside of the sealing sleeve from the air inlet pipe and passes through the inclined air holes, forming a wind curtain on the inner wall of the dust discharge pipe body. During the process of the spinneret of the rotor spinning machine discharging dust through the dust discharge pipe body, the dust will not contact the inner wall of the dust discharge pipe body, so there will be no dust adhering to the inner wall of the dust discharge pipe body resulting in blockage. Moreover, since the air outlet direction of the inclined air holes forms an acute angle with the dust discharge direction, it is beneficial to the discharge of dust.

[0013] 2. By providing the flow equalizing mesh plate, the present utility model can make the air flow inside the sealing sleeve enter the inclined air holes evenly, so that the air flow distribution inside the dust discharge pipe body is uniform.

[0014] 3. By providing the sound-absorbing sleeve and the sound-insulating sleeve, the present utility model can absorb and isolate the airflow noise flowing inside the dust discharge pipe body, playing a role in reducing the noise. BRIEF DESCRIPTION OF THE DRAWINGS

A sealing sleeve 4 is fixedly installed on the outer surface of the waste discharging pipe main body 3. An air inlet pipe 1 is fixedly connected to the outer surface of the sealing sleeve 4. The end of the air inlet pipe 1 is fixedly connected to a compressed supply device. An air filter 2 is fixedly connected to the end of the air inlet pipe 1.

Then, during the process of the rotor spinning machine spinner discharging dust through the waste discharging pipe main body 3, the dust will not contact the inner wall of the waste discharging pipe main body 3, so there will be no phenomenon that the dust adheres to the inner wall of the waste discharging pipe main body 3 and causes blockage.
