In order to avoid yarn defects, a cleaning device is generally arranged for cleaning, and the currently adopted method needs the cleaning device to be in contact with the roller, such as a velvet belt, a steel bar, a scraper and the like. To solve the above problems.

Wherein, the roller structure 110 comprises a roller, and the cotton sliver 400 is clamped by the roller for processing. The cleaning component 120 is arranged on the periphery of the roller, and when cleaning operation is performed, the cleaning component 120 can cause the airflow on the surface of the roller to change, so that flying dust 300 on the surface of the roller is blown, yarn defects formed by the flying dust 300 gathering and falling into the cotton sliver 400 are avoided, and the quality of the cotton sliver 400 is improved. And the cleaning component 120 only needs to cause the airflow change on the surface of the roller to enable the flying dust 300 to leave the surface of the roller without contact, so that the cleaning component 120 and the roller are prevented from being scratched, the cleaning component 120 and the roller are prevented from being abraded, and the service life of the cleaning component 120 and the roller is prolonged. The flying dust 300 blown up by the cleaning assembly 120 is sucked by the dust suction assembly 130 to collect the flying dust 300, so that the flying dust 300 is prevented from falling back, and the cleaning reliability is improved.

It will be appreciated that the cleaning assembly 120 may cause the flow rate of the air flow over the surface of the roller to vary, thereby creating a pressure differential over the surface of the roller to draw the airborne dust 300 off the surface of the roller and along with the air flow until it is drawn into the suction assembly 130.

In some examples, as shown in fig. 1, the cleaning assembly 120 described above includes: a cleaning member located on the periphery of the roller; a drive member connected to the cleaning member for driving the cleaning member to cause a change in the air flow at the surface of the roller.

Specifically, the cleaning roller 121 is provided with a fixed member 1211, a fixed shaft 1212, and a rotating member 1213. The fixing element 1211 is fixedly connected to the roller structure 110, the fixing element 1211 has a through hole, the fixing shaft 1212 is disposed through the through hole, and the fixing element 1211 can limit the rotational degree of freedom of the fixing shaft 1212. The driving member can be a hub motor 122, the hub motor 122 is sleeved on the fixing shaft 1212, the hub motor 122 and the fixing shaft 1212 do not rotate, only the outer ring rotates, and the rotating member 1213 is wound around the hub motor 122. Under the condition that the hub motor 122 drives the rotating member 1213 to rotate, the rotation of the rotating member 1213 can change the airflow speed on the surface of the roller, so that the flying dust 300 is pulled to be separated from the surface of the roller, and the roller is cleaned. By adopting the hub motor 122, additional transmission parts such as a belt and a gear are not needed, the fixed shaft 1212 is not needed to rotate, an additional bearing is not needed, the structure is simplified, and the maintenance difficulty and probability are reduced.

For example, the fixing element 1211 may be a fixing block having a through hole, and a bolt, wherein the fixing block has a through hole, the fixing shaft 1212 is disposed through the through hole, and the fixing block has a threaded hole, and the bolt is screwed into the threaded hole and abuts against the fixing shaft 1212 to limit the rotational degree of freedom of the fixing shaft 1212.

In some examples, as shown in fig. 3 to 6, the rotating element 1213 is a rubber sleeve, a plurality of protrusions are formed on the surface of the rubber sleeve, and a recess is formed between adjacent protrusions; or the above-mentioned rotating element 1213 is the blade 1214.

The rotating member 1213 may further include a blade 1214, and the plurality of blades 1214 are spaced outside the hub motor 122, so that when the hub motor 122 rotates, the blade 1214 can be driven to rotate, thereby causing the airflow velocity on the surface of the roller to change, and drawing the flying dust 300 off the surface of the roller.

Illustratively, the plurality of blades 1214 may be connected by a rubber sleeve, and the rubber sleeve is disposed on the hub motor 122. Or a plurality of blades 1214 may be adhesively bonded to the outside of hub motor 122. The vanes 1214 or projections may be arranged in a slanted thread pattern.

In some examples, the cleaning device 100 further comprises: a rotational speed detecting unit for detecting rotational speed information of the in-wheel motor 122; and a controller respectively connected to the rotation speed detector and the in-wheel motor 122, and configured to adjust the rotation speed of the in-wheel motor 122 to an ideal rotation speed range according to the rotation speed information of the in-wheel motor 122 sent by the rotation speed detector.

Wherein, the rotational speed detects the rotational speed information that the piece is used for detecting in-wheel motor 122, and the controller can be connected with rotational speed detects the piece and in-wheel motor 122 electricity respectively. When the cleaning device 100 performs a cleaning operation, the in-wheel motor 122 rotates, and the detected rotational speed information of the in-wheel motor 122 is sent to the controller through the rotational speed detecting member. The controller adjusts the rotational speed of the in-wheel motor 122 according to the rotational speed information so that the rotational speed is within the desired rotational speed range. The phenomenon that the flying dust 300 on the surface of the roller cannot be blown up due to the fact that the rotating speed of the hub motor 122 is too slow is avoided, and the phenomenon that the cotton sliver 400 of the roller is blown up due to the fact that the rotating speed of the hub motor 122 is too fast to influence normal operation of the roller is also avoided. Ensures that the rotating element 1213 can stably and reliably blow up the flying dust 300 from the surface of the roller.

For example, the hub motor 122 can be electronically controlled to speed and operate at a constant rotational speed after speed regulation. The hub motor 122 can be a direct current motor, and the direct current motor can be speed-regulated by a Programmable Logic Controller (PLC) analog module. The alternating current motor can be controlled by a PLC control frequency converter or a servo driver for speed regulation control. And the controller can also be provided with a touch screen, can show operating parameters such as the rotational speed of present in-wheel motor 122, and cleaning assembly 120 can automatic operation, or can control through the staff. A worker can click a control button of the touch screen to adjust the rotating speed of the hub motor 122 and the operation of the dust collection assembly 130, and the cleaning assembly 120 and the dust collection assembly 130 synchronously operate to ensure that flying dust 300 blown up by the cleaning assembly 120 can be sucked by the dust collection assembly 130 in time, so that the cleaning reliability is ensured.

The cradle 114 is connected to the seat 113, located above the first roller 111, and can move in a direction close to the first roller 111, and under the condition that the pressure of the first roller 111 and the second roller 112 on the cotton sliver 400 is lower than the ideal pressure range, the cradle 114 can be adjusted to abut against the first roller 111 and apply pressure to the first roller 111, so that the pressure on the cotton sliver 400 is increased, and the pressure falls into the ideal pressure range. In the case where the pressure of the first roller 111 and the second roller 112 against the tampon 400 exceeds the desired pressure range, the adjustable cradle 114 is moved away from the first roller 111 to reduce the pressure against the tampon 400 so that the pressure falls within the desired pressure range.
