Silk collecting device for spinning and silk collecting method

The invention relates to a silk collecting device for spinning and provides a corresponding silk collecting method, in particular to a device for collecting silk threads in spinning production and processing. The silk collecting device for spinning is characterized by comprising a box body and a collecting vehicle, the top of the box body is provided with a wire guide device and a wire winding mechanism; the wire winding mechanism comprises clamping devices at the two ends and a roller shaft installed between the two clamping devices. The clamping device comprises a bearing seat and a spline bearing installed on the bearing seat, a roller shaft seat with a spline sleeve is sleeved with the spline bearing through the spline sleeve, and the spline sleeve is connected with an air cylinder through a driving frame. The air cylinder stretches out and draws back to drive the spline sleeve to move on a spline of the spline bearing by driving the driving frame; a spline shaft of the spline bearing of one clamping devi
