Description
Technical Field
The utility model belongs to the technical field of rotor type open-end spinning machine connects and draws yarn, especially with a rotor spins storage yarn mechanism of single spindle drawing yarn and is related to.
Background
The spinning principle of the rotor spinning machine is that the fiber strip is opened into single fiber, the single fiber is conveyed into a rotor rotating at high speed along with air flow, contacts with a yarn leading head in a condensation groove and is twisted into yarn, the yarn is clamped and led out by a yarn leading roller consisting of a yarn leading shaft and a yarn leading leather roller, and then the yarn is directly wound into a yarn barrel by a winding device. When yarn breakage occurs, piecing is required. In the existing semi-automatic rotor spinning machine, before the joint, a yarn drum and a yarn leading leather roller are lifted, the yarn leading yarn head hung on a yarn hanging head of a sinking electromagnet is fixed in length manually, then a spinning device is opened, a rotating shaft of a rotor is separated from friction of a tangential belt, and the rotor is cleaned after stopping. When the yarn is connected, the spinning device is closed, the rotating shaft of the rotating cup is driven by the tangential belt to rotate, and the yarn end is put into the yarn-drawing tube. The spinning device feeding mechanism feeds fibers to a rotating cup rotating at a high speed, a yarn hanging head of a sinking electromagnet retracts to remove hanging yarn, the yarn head is attracted by negative pressure through a yarn guide tube to reach the rotating cup to be in contact winding with a fed fiber ring, and the yarn is twisted into yarn and led out. The joint action is completed according to the time parameters of feeding, yarn sinking, yarn leading and the like set by the process. After the joint is successful, the bobbin falls down on a winding friction roller for winding. However, in the conventional spinning and piecing process, after piecing is completed, because the starting acceleration of the yarn guiding shaft and the yarn drum is different, the condition of yarn floating can be caused, and the yarns are guided together in a lump and are not in a stretched straight state.
SUMMERY OF THE UTILITY MODEL
To current at traditional spinning joint in-process, connect the back because the start-up acceleration of drawing a yarn axle and a yarn section of thick bamboo is different, can cause the condition of the yarn that wafts, the yarn has one to stick together and draws the yarn, is not the problem of the state of straightening, the utility model aims at providing a rotor spins the yarn storage mechanism of single spindle yarn of drawing.
Therefore, the utility model adopts the following technical scheme: the utility model provides a rotor spins storage yarn mechanism of single spindle doff, rotor spins the doff mechanism and includes doff leather roller and doff roller, and the cooperation contact is drawn the yarn between doff leather roller and the doff roller, and the doff roller passes through roller motor drive and rotates, and the doff leather roller passes through the back shaft support to be installed in the one end of rotor arm, and the middle-section part of rotor arm passes through rotary driving mechanism to be connected in the frame, characterized by, storage yarn mechanism include the yarn storage tube, the one end of yarn storage tube is just to the yarn of rotor spinning doff mechanism front side, stores up the yarn tube tail portion and connects negative pressure suction mechanism.
As the supplement and improvement to the technical proposal, the utility model also comprises the following technical characteristics.
The yarn storage tube is obliquely arranged, so that yarn guiding of the yarn storage tube to yarns during joint is facilitated.
The rotor spinning yarn leading mechanism further comprises a pressure spring, a Hall sensor and magnetic steel, the pressure spring is arranged at the top of the other end of the rotating arm, the magnetic steel and the pressure spring are installed in a matched mode, the Hall sensor is installed on one side of the magnetic steel, and the Hall sensor is used for sensing the magnetic field change between the magnetic steel and the pressure spring.
The pressure spring is sleeved on the vertical supporting shaft, two ends of the supporting shaft are positioned and installed through the support, and the other end of the rotating arm is arranged below the pressure spring.
The other end of the rotating arm is provided with a ring sleeve part sleeved on the supporting shaft, and the rotating arm is sleeved on the supporting shaft through the ring sleeve part.
The utility model discloses following beneficial effect can be reached: 1. the utility model discloses a set up the yarn storage tube in the front side of yarn guide mechanism, the rotation of yarn guide roller motor is sent the yarn earlier to the yarn through the negative pressure and is stored up in the yarn to the condition that appears wafing the yarn when preventing that the yarn from connecting prevents that the yarn can run out the detection range of sensor. 2. The utility model discloses an afterbody at the rotor arm increases magnet steel and hall sensor, and when the leather roller was pressed to the dolly, hall sensor accomplished the joint action for signal to single spindle control system after the delay time of settlement to remove from and need press the repetitive motion of a sensor again after putting the yarn when connecting, improve joint efficiency.
