A device for easy installation and disassembly of high-speed spinning rotor free end

Abstract

The invention relates to the field of spinning rotors, and discloses a device for facilitating the installation and disassembly of the free ends of high-speed spinning rotors, including spinning rotors, and the fixed part on the spinning rotors is connected to the rotor shaft through a connecting mechanism. Fixed connection, the connection mechanism includes a fixed sleeve, the fixed part on the spinning rotor and one end of the rotor shaft both extend into the interior of the fixed sleeve and cooperate with each other. Through the fixed connection between the fixed sleeve and the rotor shaft, a certain force will be applied to the fixed sleeve, and the fixed sleeve can be installed on the rotor shaft. After the fixed sleeve is rotated until the position of the stopper corresponds to the position of the groove on the rotor shaft, the stopper It pops up under the action of the torsion spring and completes the clamping with the groove, and the separation of the rotor shaft and the fixed sleeve does not require dismantling the machine, only need to rotate along the direction of the rotor shaft after stopping, and press the stopper into the installation It can be removed in the tank, which is simple and convenient, effectively improves maintenance efficiency and improves the efficiency of the factory.

Description

technical field [0001] The invention relates to the field of spinning rotors, in particular to a device for facilitating the installation and disassembly of the free ends of high-speed spinning rotors. Background technique [0002] Air spinning is through the high-speed rotating cup in the spinning device and the negative pressure in the cup to complete fiber transportation, cohesion, merging, and twisting into yarn. Therefore, the speed of the spinning rotor determines the spinning efficiency. In the spinning device at the free end, for example, when the speed is above 130,000 / min, the spinning rotor is usually rotated magnetically to meet the radial deflection and support, but in order to optimize the anti-rotation force and inertia, the spinning rotor is usually rotated. The weight of the spinning rotor is reduced, so that the thickness of the spinning rotor is relatively thin.

[0002] Air spinning is through the high-speed rotating cup in the spinning device and the negative pressure in the cup to complete fiber transportation, cohesion, merging, and twisting into yarn. Therefore, the speed of the spinning rotor determines the spinning efficiency. In the spinning device at the free end, for example, when the speed is above 130,000 / min, the spinning rotor is usually rotated magnetically to meet the radial deflection and support, but in order to optimize the anti-rotation force and inertia, the spinning rotor is usually rotated. The weight of the spinning rotor is reduced, so that the thickness of the spinning rotor is relatively thin. Therefore, at the same speed, the wear of the thinner spinning rotor will be serious, and it needs to be replaced frequently.

[0003] Existing spinning rotors are usually connected to the rotor shaft by threads or pins. This connection method requires extensive disassembly of the equipment when replacing the spinning rotor, and the maintenance efficiency is low.
