[0002] The start-up method of the existing rotor spinning machines on the market is completed by starting the whole vehicle, and then the operator starts jointing one spindle at a time. Since the number of spindles in rotor spinning reaches as many as 500 spindles or even more, this jointing operation The method is equivalent to that the whole vehicle needs to be driven empty for more than 2 hours after starting, which leads to waste of production energy consumption of the rotor spinning machine, and the production efficiency is also greatly reduced

Embodiment Construction
[0010] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0011] like figure 1 As shown, the rotor spinning method of the present invention based on the energy-saving start-up method of the yarn drawing and winding device includes the following steps:
[0012] In the first step, before the whole vehicle of the rotor spinning machine is started, the process fan on the spinning-in device of each spindle is turned on in turn and the yarn is drawn, and the yarn on the spinning-in device of each spindle is wound 1. Lead down from the paper tube 2 and pass through the broken yarn sensor 4, then pass through the middle of the top roller 5 and the yarn delivery shaft 6 and be pressed and fixed by the top roller. Turn off the process fan when finished;
[0013] In the second step, after all yarn drawing and winding devices finish yarn drawing, start all rotor motors, carding motors and process fans on the v...

The invention discloses an energy-saving start method for rotor spinning based on doffing and winding threading devices. The method comprises the following steps: sequentially starting process fans oneach spindle of doffing and winding threading device and performing doffing before complete start of a rotor spinning machine, leading down yarns of each spindle of doffing and winding threading device from a paper tube so as to pass through a broken yarn sensor, passing through the middle of a leather roller and a doffing axis, fixedly pressing by the leather roller, enabling the yarn heads to stretch into a doffing tube to complete doffing, and stopping the process fans after the doffing operation is completed; starting all rotor motors, carding motors and process fans after all the doffingand winding threading devices complete doffing; transmitting instructions by a PLC (Programmable Logic Controller) after start completion, respectively starting servo motors capable of controlling the doffing axis and a winding roller to rotate on the doffing and winding threading device of each spindle, and doffing the yarns to the paper tube by virtue of reverse fit of the doffing axis and thewinding shaft. According to the method disclosed by the invention, the energy consumption of the rotor spinning machine is greatly reduced, and the production efficiency of the rotor spinning machineis improved.
Description
technical field [0001] The invention belongs to the technical field of starting methods for rotor spinning machines, and in particular relates to an energy-saving starting method for rotor spinning based on a yarn drawing winding spinning-in device. Background technique [0002] The starting method of the existing rotor spinning machines on the market is completed by starting the whole vehicle, and then the operator starts splicing one spindle by one. Since the number of spindles in rotor spinning is as high as 500 spindles or even more, this kind of splicing operation The method is equivalent to that the whole vehicle needs to be driven empty for more than 2 hours after starting, which leads to waste of production energy consumption of the rotor spinning machine, and the production efficiency is also greatly reduced. Contents of the invention [0003] In view of the problems existing in the above-mentioned background technology, the present invention aims to provide an en...
