Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-4, a yarn tension control device for a rotor spinning machine includes a spinning cup sensor, a yarn guiding device, a yarn detector, a yarn absorbing device and a winding device, which are sequentially arranged, wherein the yarn absorbing device includes a yarn absorbing tube, a gas collecting tube, a valve for controlling the on-off of the port of the gas collecting tube, and a stepping motor for enabling the gas collecting tube and the yarn absorbing tube to generate negative pressure, two ends of the gas collecting tube are respectively provided with a plurality of yarn absorbing tubes, and the yarn absorbing tubes are communicated with the gas collecting tube; the rotor spinning machine is provided with a machine head display, a machine head controller in two-way connection with the machine head display and a machine body control panel arranged on each section of machine body, the machine body control panel of each section of machine body is in two-way connection with the machine head controller through a data bus, the input end of each section of machine body control panel is connected with a plurality of rotor sensors arranged on the section of machine body, and the output end of each section of machine body control panel is connected with a stepping motor of the section of machine body.
The gas collecting pipe is a pipeline with an L-shaped structure, two ends of the gas collecting pipe are correspondingly arranged on the left side machine body and the right side machine body of the section, and the gas collecting pipe is provided with a plurality of yarn absorbing pipes communicated with the gas collecting pipe.
And a control chip is arranged in the machine body control panel of each section of machine body and is used for receiving signals sent by a plurality of spinning cup sensors of the section of machine body.
The utility model provides a control yarn tension device for rotor type open-end spinning machine is last, open the valve through fuselage control panel control step motor, the yarn that the suction tube is not enough with tension is inhaled the suction tube and is kept in by the yarn of convoluteing, thereby guarantee the elasticity and the shaping of yarn section of thick bamboo, on the other hand, step motor of each section fuselage control panel individual control, and then the negative pressure volume that does not influence the complete machine, can effective control yarn tension, single section independent control, any one spinning cup sensor in a section detects the joint signal and can both trigger the action, furthest reduces the change of complete machine technology negative pressure, it is higher to improve the resultant yarn quality and control the precision.
When a signal joint is monitored by a rotor sensor, a stepping motor is controlled by a machine body control panel to open a valve, so that a gas collecting pipe and an absorbing bobbin connected with a process negative pressure pipe generate certain negative pressure, a section of yarn with insufficient tension between a yarn guiding device and a winding device is sucked into the absorbing bobbin for temporary storage, the tightness and the forming of a yarn bobbin are ensured, and when the joint is successful, the yarn which is temporarily stored is pulled out of the absorbing bobbin to enter normal spinning.
