Description
Technical Field
The utility model relates to a torque sensor and receive silk machine.
Background
The yarn collecting machine is used for collecting and winding the yarn on a winding roller. And the yarn is paid off from the pay-off mechanism, travels to the yarn collecting machine and is wound by the yarn collecting machine. In the winding process, the uniformity of the yarn wound on the winding roller is determined by the tightness of the yarn. Also, over-loosening or over-tightening yarn breakage is to be avoided. In the prior art scheme, the distance between the yarn guide rod and the yarn guide rod is adjusted by adjusting the height position of the swinging rod, so that the tightness of the yarn is adjusted. And the tightness of the yarn is realized by sensing the rotation angle of the swinging rod by an angle sensor. Then, the corresponding high-low position of the swinging rod is adjusted according to the data of the angle sensor, and further the adjustment of the yarn tightness is realized.
The above method has many problems, when in first and second production, the multiple yarn collecting machines work simultaneously, and the height positions of the swing rods of the different yarn collecting machines are not consistent, so that the reacted yarn tension, namely the tightness, is different, and the difference can not be adjusted, so that the tightness of the wound yarn is different. Secondly, the adjustment of the height position of the oscillating lever is experience-dependent. And thirdly, the angle sensor indirectly senses the yarn tightness, and feeds back an approximate analog quantity or duty ratio by sensing the rotation angle of the swinging rod, so that the accuracy is not high. Fourthly, because the swinging rod has a stroke range, when the stroke range is not timely adjusted because of the advancing speed of the yarn fed by the front end, the phenomenon of stroke overflow or over-low can be generated, when the stroke overflows, the yarn can not bear the pulling after the swinging rod overflows to cause yarn breakage, and when the stroke is over-low, the yarn tension is over-low. Fifth, the oscillating lever rotates to cause loss of the bearings.
