Description

Technical Field

[0001] This utility model belongs to the technical field of spinning equipment accessories, specifically relating to a rotor of a self-cleaning rotor spinning machine. Background Technology

[0002] Rotor spinning technology, as an important branch of modern spinning processes, uses the rotor, a core component, to achieve fiber cohesion, twisting, and yarn formation through centrifugal force generated by high-speed rotation.

[0003] Traditional rotors typically employ a monolithic design, precision-machined from a single metal material. Their functional areas include the coagulation tank, the sliding surface on the inner wall, and the connecting seat. With the textile industry's increasing demands for yarn quality, equipment efficiency, and clean production, existing rotor structures operate under high-speed (60,000-120,000 rpm) and high-temperature (80-120°C) conditions. Friction between fibers and the metal surface easily generates electrostatic adsorption, leading to fiber residue buildup in the coagulation tank. Traditional solutions involve periodic shutdowns for manual cleaning or increasing surface smoothness; however, the former requires maintenance, reducing production efficiency, while the latter cannot guarantee wear resistance due to material limitations. Furthermore, different fiber raw materials (cotton, linen, synthetic fibers, etc.) and yarn counts require specific parameters such as coagulation angle and channel curvature. Traditional monolithic rotors cannot achieve process optimization through localized structural adjustments, forcing companies to stock multiple rotor components, significantly increasing equipment investment. Moreover, different functional areas of the rotor have varying material performance requirements. For example, the coagulation tank requires high hardness and wear resistance to resist fiber erosion, while the rotor matrix needs to balance lightweight and dynamic balance. Traditional single-element materials are difficult to meet these gradient performance requirements, making it difficult to simultaneously optimize rotor life and energy consumption. Therefore, this invention proposes a self-cleaning rotor for a spinning machine, which facilitates rotor replacement, reduces equipment procurement costs, and simultaneously achieves lightweight and dynamic balance characteristics, reducing friction between fibers and the rotor surface to achieve self-cleaning. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotor of a self-cleaning rotor spinning machine, comprising a rotor body, a rotor base, and a connecting assembly. The inner wall of the rotor body is provided with a sliding surface, and the rotor body is provided with a coagulation groove at the bottom end of the sliding surface. Both the sliding surface and the coagulation groove of the rotor body are coated with a non-stick coating. An interface is provided at the bottom end of the rotor body. The center of the rotor base is fastened to the rotor drive shaft of the spinning machine by screws. A positioning platform adapted to the interface at the bottom end of the rotor body is provided at the top end of the rotor base. The connecting assembly includes a positioning pin and a gasket. The positioning platform of the rotor body and the rotor base are fastened together by the positioning pin.

[0005] As a preferred embodiment of this utility model, both the cup body and the cup base are integrally formed structures.

[0006] As a preferred embodiment of this utility model, a gasket is installed between the cup body interface and the positioning platform of the cup holder.

[0007] As a preferred technical solution of this utility model, the cup body is made of lightweight alloy or ceramic composite material.

[0008] As a preferred embodiment of this utility model, the cup holder is made of high-strength steel.

[0009] As a preferred embodiment of this invention, the non-stick coating is a diamond carbon (DLC) coating.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) The split design of the cup body and cup holder facilitates the replacement of the cup body according to different fiber raw materials and yarn count specifications. Enterprises do not need to stock a large number of integral rotor components, reducing equipment procurement costs. Moreover, the split design allows the cup body and cup holder to be made of the most suitable materials. The cup body is made of lightweight alloy or ceramic composite material, achieving lightweight and dynamic balance characteristics. The low density of the lightweight alloy reduces the inertial force of the rotor when rotating at high speed, thus reducing energy consumption. The cup holder is made of high-strength steel, which can withstand the strong centrifugal force and torque generated by the high-speed rotation of the rotor. This ensures the firmness and stability of the connection between the cup holder and the rotor drive shaft of the spinning machine, avoiding problems such as unstable rotor operation and excessive vibration caused by loose connection.

[0012] (2) The diamond carbon (DLC) coating on the sliding surface of the cup and the surface of the condensation tank greatly reduces the friction between the fiber and the surface of the cup due to its low coefficient of friction. This makes it less likely for the fiber to be attracted to the surface of the cup due to static electricity generated by friction during the sliding and condensation process, thus achieving self-cleaning and effectively avoiding the problem of frequent shutdowns for cleaning caused by fiber residue accumulation in the condensation tank in traditional rotary cups.

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. Example

[0018] Please see Figure 1-2 The present invention provides the following technical solution: a rotor of a self-cleaning rotor spinning machine, comprising a rotor body 1, a rotor seat 2 and a connecting assembly. The inner wall of the rotor body 1 is provided with a sliding surface 4. A coagulation groove 5 is provided at the bottom of the rotor body 1 located on the sliding surface 4. The surfaces of the sliding surface 4 and the coagulation groove 5 of the rotor body 1 are coated with a non-stick coating 6. An interface 7 is provided at the bottom of the rotor body 1. The center of the rotor seat 2 is fastened to the rotor drive shaft of the spinning machine by screws. A positioning platform 8 adapted to the interface 7 at the bottom of the rotor body 1 is provided at the top of the rotor seat 2. The connecting assembly includes a positioning pin 3 and a gasket 9. The interface 7 of the rotor body 1 and the positioning platform 8 of the rotor seat 2 are fastened together by the positioning pin 3.

[0019] In order to ensure the stability and integrity of the rotating cup structure, reduce assembly errors, and improve the mechanical performance and reliability of the rotating cup, in this embodiment, as a preferred technical solution of the present invention, the cup body 1 and the cup base 2 are both integrally formed structures.

[0020] To increase the tightness of the connection and prevent loosening and detachment, and to enhance the sealing of the connection between the cup body 1 and the cup base 2 to prevent impurities, dust and other contaminants from entering the interior of the rotating cup, in this embodiment, as a preferred technical solution of the present invention, a gasket 9 is installed between the interface 7 of the cup body 1 and the positioning platform 8 of the cup base 2.

[0021] In order to reduce the overall weight of the rotor, reduce the inertial force and energy consumption during rotor rotation, and improve the stability of rotor operation while ensuring the strength and wear resistance of the rotor, in this embodiment, as a preferred technical solution of the present invention, the material of the rotor body 1 is a lightweight alloy or ceramic composite material.

[0022] In order to enable the cup holder 2 to withstand the huge centrifugal force and torque generated when the rotor rotates at high speed, to ensure the stability of the connection between the cup holder 2 and the rotor drive shaft of the spinning machine, and to ensure the reliability of power transmission, in this embodiment, as a preferred technical solution of the present invention, the cup holder 2 is made of high-strength steel.

[0023] In order to ensure an extremely low surface friction coefficient and good chemical inertness, reduce the frictional resistance and electrostatic adsorption between the fiber and the surface of the cup 1, effectively prevent the fiber from remaining and accumulating in the coagulation tank 5 and the sliding surface 4, and realize the self-cleaning function of the rotating cup, in this embodiment, as a preferred technical solution of the present invention, the non-stick coating 6 is a diamond carbon (DLC) coating.

[0024] In summary, with the help of the above-mentioned technical solution of this utility model, the components in the rotor structure of the self-cleaning rotor spinning machine work together to achieve efficient spinning and solve many problems faced by traditional rotors.

[0025] Overall Structure and Installation: The rotor mainly consists of a rotor body 1 and a rotor base 2. The rotor base 2 is screwed to the center of the spinning machine rotor drive shaft, providing a stable power connection and support for the entire rotor. A positioning platform 8 is located at the top of the rotor base 2, which mates with the interface 7 at the bottom of the rotor body 1. The two are secured by a positioning pin 3. This connection method ensures a precise positional relationship between the rotor body 1 and the rotor base 2, maintaining stability during high-speed rotation. Simultaneously, a gasket 9 is installed between the interface 7 of the rotor body 1 and the positioning platform 8 of the rotor base 2 to increase the tightness of the connection and prevent loosening or detachment. It also provides a good seal, preventing foreign objects from entering during high-speed rotor rotation and affecting spinning quality.

[0026] Structure and function of cup body 1: The inner wall of cup body 1 is provided with a sliding surface 4. When the rotor rotates at high speed, the fibers move along the sliding surface 4 towards the bottom of cup body 1 under the action of centrifugal force. A coagulation groove 5 is provided at the bottom of the sliding surface 4 of cup body 1, where the fibers coagulate and are ready for twisting into yarn. Both the sliding surface 4 and the coagulation groove 5 of cup body 1 are coated with a non-stick coating 6, which is a diamond carbon (DLC) coating. Due to the extremely low coefficient of surface friction and good chemical inertness of the DLC coating, it can effectively reduce the frictional resistance between the fibers and the surface of cup body 1, reduce the possibility of static electricity generation, and thus prevent the fibers from accumulating in the coagulation groove 5 due to electrostatic adsorption, achieving a self-cleaning function, reducing the number of downtime cleanings, and improving production efficiency.

[0027] Material Characteristics and Advantages: The cup body 1 is made of lightweight alloy or ceramic composite material. Lightweight alloy is characterized by its light weight and high strength, which can reduce the inertial force when the rotor rotates at high speed, reduce energy consumption, and ensure the dynamic balance performance of the rotor under high-speed operation. Ceramic composite material has the characteristics of high hardness, wear resistance, and high temperature resistance, which can adapt to the long-term operation of the rotor at high temperature conditions of 80-120℃, and can resist the erosion and wear of fibers, extending the service life of cup body 1. The cup base 2 is made of high-strength steel. High-strength steel has high yield strength and tensile strength, which can withstand the huge centrifugal force when the rotor rotates at high speed, ensuring a stable connection between the rotor and the drive shaft, and ensuring the stable operation of the entire rotor system.

[0028] Process adaptability: Different fiber raw materials (cotton, linen, chemical fibers, etc.) and yarn counts require specific parameters such as cohesion angle and channel curvature. This invention, through the structural design of the cup body 1 and cup holder 2, allows for adaptation to different process requirements to a certain extent by replacing cup bodies 1 with different specifications. Because the cup body 1 and cup holder 2 adopt a modular design, replacing the cup body 1 is relatively convenient. Enterprises do not need to stock a large number of complete rotor components of different specifications, reducing equipment investment costs. At the same time, it allows for more flexible adjustment of rotor parameters according to production needs, optimizing the spinning process.
