Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, specifically to an anti-tangle combing roller for rotor spinning machines. Background Technology

[0002] The carding roller is one of the core components of a rotor spinning machine (also known as an air-jet spinning machine). It directly participates in the fiber pretreatment and yarn forming process, and its performance directly affects the uniformity, strength and cleanliness of the yarn. The carding roller is located between the fiber feeding system and the rotor of the rotor spinning machine. It is responsible for pretreating the fed fibers to provide a uniform and loose fiber flow for subsequent cohesion and twisting.

[0003] Chinese Patent Publication No. CN201952544U discloses an integral end cap and a fixed gear ring between the combing roller body and the end cap. The key feature is that an internal thread is formed in the inner hole of the end cap, and an external thread matching the internal thread of the end cap is formed on the outer circumference of the combing roller body. The end cap and the combing roller body are fixed together by the combination of the internal and external threads, thus securing the gear ring between them. This utility model provides a combing roller for a rotor spinning machine, using a threaded connection between the combing roller body and the end cap. This simplifies the manufacturing process and ensures machining accuracy. During use, because the tightening direction of the end cap is consistent with the bearing's rotation direction, the connection between the combing roller body and the end cap tightens with each rotation, completely preventing the end cap from loosening.

[0004] The existing combing rollers have combing needles or combing teeth fixed on them. When working, there is a certain probability that the fibers will get tangled on the combing needles or combing teeth. Over time, a large number of fibers will get tangled on the combing roller, which will affect the working effect and efficiency of the combing roller. To address this, we propose an anti-tangling combing roller for rotor spinning machines. Utility Model Content

[0021] Please refer to Figures 1-4. An anti-tangle combing roller for a rotor spinning machine includes a combing roller 1. An mounting cylinder 11 is installed on the left side of the combing roller 1. A second connecting bearing 17 is installed inside the mounting cylinder 11. A transmission cylinder 12 passes through the second connecting bearing 17. An internal gear 18 is installed on the inner wall of the transmission cylinder 12. A first transmission gear 13 is installed inside the internal gear 18. A second transmission gear 14 is installed below the first transmission gear 13. A third transmission gear 16 is installed below the second transmission gear 14. A third connecting bearing 19 is installed inside the first transmission gear 13. A first connecting bearing 15 is installed on the left side of the inner wall of the mounting cylinder 11. A transmission shaft 10 passes through the first connecting bearing 15. A first magnet 2 and a third magnet 9 are installed on the outer surface of the transmission shaft 10. A limiting movable pin hole 20 is opened on the inner wall of the combing roller 1. A combing needle 4 passes through the limiting movable pin hole 20. A limiting plate 3 is installed below the combing needle 4. A second magnet 6 is installed below the sizing roller 1, a first rubber buffer pad 5 is installed on the upper surface of the limiting plate 3, a limiting cylinder 8 is installed inside the combing roller 1, and a second rubber buffer pad 7 is installed on the outer surface of the limiting cylinder 8.

[0022] In this implementation scheme: by setting a retractable combing needle 4, which cooperates with the second magnet 6 and the rotating first magnet 2 and third magnet 9, the combing needle 4 is pushed to extend and retract within the limiting movable needle hole 20, thereby pushing down the yarn wrapped on the combing needle 4 and playing an anti-tangling role.

[0023] Furthermore:

[0024] In an optional embodiment, the diameter of the combing needle 4 matches the diameter of the limiting movable needle hole 20, and the combing needle 4 moves inside the limiting movable needle hole 20.

[0025] In this implementation scheme: when the combing needle 4 extends or retracts inside the limiting movable needle hole 20, the limiting movable needle hole 20 can push down the fibers wrapped around the combing needle 4.

[0026] Furthermore:

[0027] In an optional embodiment, the transmission cylinder 12 is movably connected to the mounting cylinder 11 via a second connecting bearing 17, and the transmission cylinder 12 is fixedly connected to the combing roller 1.

[0028] In this implementation scheme: when the transmission cylinder 12 rotates, it can drive the combing roller 1 to rotate and work.

[0029] Furthermore:

[0030] In an optional embodiment, the first transmission gear 13 is movably connected to the mounting cylinder 11 via the third connecting bearing 19, the second transmission gear 14 is movably connected to the mounting cylinder 11, the first transmission gear 13 is meshed with the internal gear 18, the first transmission gear 13 is meshed with the second transmission gear 14, and the second transmission gear 14 is meshed with the third transmission gear 16.

[0031] In this implementation scheme: when the drive shaft 10 rotates, it drives the drive cylinder 12 to rotate in the same direction as the drive shaft 10 through the third drive gear 16, the first drive gear 13, the second drive gear 14, and the internal gear 18. At the same time, the size and number of teeth of the third drive gear 16 are different from those of the internal gear 18, ensuring that the rotational speeds of the drive shaft 10 and the drive cylinder 12 are different.

[0032] Furthermore:

[0033] In an optional embodiment, the drive shaft 10 is movably connected to the mounting cylinder 11 via a first connecting bearing 15, the drive shaft 10 passes through the interior of the third drive gear 16, and the drive shaft 10 is fixedly connected to the third drive gear 16.

[0034] In this implementation scheme: when the drive shaft 10 rotates, it can drive the drive cylinder 12 to rotate stably.

[0035] Furthermore:

[0036] In an optional embodiment, both the first magnet 2 and the third magnet 9 are rotated inside the limiting cylinder 8 via the transmission shaft 10, with the first magnet 2 and the second magnet 6 having opposite poles facing each other, and the third magnet 9 and the second magnet 6 having the same poles facing each other.

[0037] In this implementation scheme: when the first magnet 2 and the second magnet 6 are opposite to each other, opposite poles attract each other, causing the combing needle 4 to retract into the interior of the limiting movable needle hole 20. When the third magnet 9 and the second magnet 6 are opposite to each other with the same poles, the combing needle 4 is pushed out from the interior of the limiting movable needle hole 20, thereby realizing the extension and retraction of the combing needle 4 inside the limiting movable needle hole 20.

[0038] Working Principle: When using the anti-tangle combing roller for a rotor spinning machine, firstly, the mounting cylinder 11 is installed onto the rotor spinning machine using bolts, and then the combing roller 1 is installed inside the rotor spinning machine. The output end of the motor is keyed to the drive shaft 10. When the rotor spinning machine is working, the motor drives the drive shaft 10 to rotate at high speed, simultaneously driving the first magnet 2 and the third magnet 9 to rotate. Simultaneously, the rotating drive shaft 10, through the third drive gear 16, the second drive gear 14, the first drive gear 13, and the internal gear 18, drives the drive cylinder 12 and the combing roller 1 to rotate in the same direction as the drive shaft 10. Because the third drive gear 16 and the internal gear 18 have different dimensions, the drive shaft 10 and the drive cylinder 12 rotate at different speeds, resulting in a certain speed difference. This causes the first magnet 2 and the third magnet 9 to rotate relative to each other inside the combing roller 1. When the first magnet 2 rotates to the position corresponding to the second magnet 6, due to the rotation of the first magnet 2 to the position corresponding to the second magnet 6... Due to the attraction between opposite poles, the second magnet 6 moves towards the direction of the first magnet 2. When the second magnet 6 contacts the second rubber buffer pad 7 on the limiting cylinder 8, it stops moving, thereby causing the combing needle 4 to retract into the interior of the limiting movable needle hole 20. In this way, the yarn wrapped around the combing needle 4 is pushed off. As the drive shaft 10 rotates, when the third magnet 9 rotates to the position corresponding to the second magnet 6, the third magnet 9 and the second magnet 6 move in opposite directions, pushing the second magnet 6 away from the limiting cylinder 8. This causes the combing needle 4 to extend out from the interior of the limiting movable needle hole 20. When the first rubber buffer pad 5 on the limiting plate 3 contacts the inner wall of the combing roller 1, it stops moving. This is the working principle of the anti-winding combing roller of the rotor spinning machine.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
