Description

Technical Field

[0001] This utility model relates to the field of rotor spinning machine technology, specifically a rotor spinning machine with a waste removal and combing mechanism. Background Technology

[0002] Rotor spinning machines are a mainstream type of spinning equipment. The principle is that the fed fiber sliver (such as cotton sliver) is opened into single fibers by a rotating carding roller covered with carding cloth. These fibers are then transported by airflow to the inner wall of a high-speed rotating rotor, where they form yarn tails in a condensing trough. At the same time, they are twisted into yarn and drawn out. It is also called an air-jet spinning machine. It includes multiple spinning units (or spinnerets). Each spinning unit mainly includes a feeding mechanism, a carding mechanism, a waste removal mechanism, and a condensing and twisting mechanism.

[0003] A search revealed that existing technologies, such as the one in publication number CN221877274U, for a waste removal and combing mechanism in a rotor spinning machine, include a waste removal duct body, a combing roller body, a fan, a cleaning component, and a spraying component. The cleaning component includes an air guide duct located on the inner wall of the waste removal duct body away from the fan, a drive shaft located inside the air guide duct, and a support plate detachably installed at the bottom of the waste removal duct body. An electric telescopic rod is installed on the top of the support plate. A second storage rod is detachably installed in a ring at equal intervals on the outer wall of the drive shaft. A second extension rod is elastically connected to the inner wall of the second storage rod via a second return spring. The cleaning component guides and collects generated impurities, and effectively cleans and discharges the collected impurities using sweeping and scraping methods, ensuring the normal operation of the waste removal process. The spraying component wets the impurities, reducing the probability of impurities accumulating and adhering to the inner wall of the air guide duct.

[0004] In summary, existing rotor spinning machines can reduce the probability of impurities accumulating and adhering to the inner wall of the air guide tube. However, it is inconvenient to replace the carding roller body in the later stages of existing rotor spinning machines. Therefore, a rotor spinning machine with a waste removal and carding mechanism is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a rotor spinning machine with a waste removal and combing mechanism, wherein two sets of L-shaped fixing plates 2 are symmetrically arranged on the outer side of the housing 1, and the L-shaped fixing plates 2 are connected to the positioning plate 202 through an electric telescopic rod 201.

[0025] To further explain, a fan 4 is installed inside the housing 1, and a gas flow port 401 is provided on the housing 1 to cooperate with the fan 4. A dust filter is installed inside the gas flow port 401. By setting the dust filter, dust can be prevented from entering the housing 1.

[0026] Specifically, the housing 1 has symmetrically arranged limiting plates 501 that cooperate with the collection box 5. The blower 4 can blow impurities into the collection box 5. A pull ring can be provided at the outer end of the collection box 5 to facilitate pulling the collection box 5 later. The housing 1 has symmetrically installed telescopic baffles 6 that cooperate with the collection box 5 on both sides of the opening end. The telescopic baffles 6 include baffles 601, and one end of the baffles 601 extends into the mounting box 602 and is connected to the sliding plate 603. One side of the sliding plate 603 is connected to the inner wall of the mounting box 602 by a spring 604, and the sliding plate 603 is connected to the mounting box 602. 02 Internal sliding connection, the outer side of the mounting box 602 is provided with a pull plate 605 to drive the sliding plate 603 to move. The position of the collection box 5 can be limited by the setting of the limiting plate 501 and the telescopic baffle 6. When it is necessary to remove the collection box 5 from the inside of the housing 1, the pull plate 605 is pulled. Under the action of the pull plate 605, the sliding plate 603 moves. At this time, the spring 604 is in a compressed state. The sliding plate 603 drives the baffle 601 to move. When the baffle 601 no longer obstructs the movement of the collection box 5, the collection box 5 can be removed from the inside of the housing 1.

[0027] Specifically, a set of positioning plates 202 are equipped with a drive motor 203. The positioning plates 202 and the L-shaped fixing plate 2 are slidably connected, and the drive motor 203 can drive the first rotating groove 204 to rotate. Another set of positioning plates 202 are rotatably connected to the second rotating groove 205. A rectangular limiting block 206 is provided at the center of the first rotating groove 204 and the second rotating groove 205. A combing roller 3 is provided inside the housing 1, and a drive column 301 is fixedly provided at the center of both ends of the combing roller 3. The drive column 301 is respectively inserted into the first rotating groove 204 and the second rotating groove 205.

[0028] To further explain, the housing 1 is provided with a movable through groove that works in conjunction with the first rotating groove 204 and the second rotating groove 205.

[0029] In a further embodiment, a limiting block groove is provided at the center of the drive column 301 to cooperate with the rectangular limiting block 206. By setting the rectangular limiting block 206 and the limiting block groove, the drive column 301 can be prevented from rotating inside the first rotating groove 204 and the second rotating groove 205.

[0030] When it is necessary to drive the combing roller 3 to rotate and comb, turn on the drive motor 203. Under the action of the drive motor 203, the drive column 301 and the combing roller 3 are driven to rotate and comb through the first rotating groove 204. When it is necessary to replace the combing roller 3, take out the impurity collection box 5. After taking it out, turn on the electric telescopic rod 201. Under the action of the electric telescopic rod 201, the first rotating groove 205 and the second rotating groove 204 move further and further away. When the first rotating groove 205 and the second rotating groove 204 are no longer in contact with the drive column 301, the combing roller 3 can be taken out and replaced.
