Exemplary winding pin pushing and pulling pin mechanism

As shown in fig. 1, the winding pin pushing and pulling pin mechanism 100 includes: the position switching mechanism 110 includes a first moving portion 111 reciprocating along a first direction, and a plurality of pushers connected to the first moving portion 111 respectively and disposed at intervals and offset in a second direction, the second direction being different from the first direction, and preferably perpendicular to the first direction and the second direction. The driving mechanism 120 includes a second moving portion 121 reciprocating in the second direction, and the second moving portion 121 is connected to the position switching mechanism 110 so that the plurality of pushers can push or pull the needle in the second direction.

The plurality of pushing pieces and the plurality of winding needle bodies of the winding needle are arranged in a one-to-one correspondence mode, and the first direction and the second direction can be perpendicular to each other. In the used state of the needle winding and pulling mechanism 100, the first direction is a vertical direction, and the second direction is a direction parallel to the axis of the needle winding cylinder. The plurality of pushing members are respectively connected to the first moving part 111 such that the plurality of pushing members can move upward or downward in the first direction. The first moving portion 111 of the position switching mechanism 110 is connected to the second moving portion 121, so that the first moving portion 111 can drive the plurality of pushing members to move in the second direction, and the pushing members can push or pull the plurality of winding needle bodies of the winding needle in the axial direction. Taking the two pushing members as an example, after one pushing member pulls out one needle winding body, the other pushing member moves to the position of the other needle winding body synchronously due to the distance of the two pushing members in the second direction, and when the second moving portion 121 continues to move, the other pushing member pulls out the other needle winding body.

When the needle bodies of the winding needle are all pulled out and the second moving part 121 returns, the other pushing piece can push the winding needle body close to the winding drum in the winding needle group rotating to the station into the needle cylinder. When the needle winding group which does not need to push or pull the needle rotates to the station, the first moving part 111 can drive the second moving part 121 to slide upwards, so that the needle winding group is avoided, and the normal rotation of the needle winding group cannot be influenced.

The distance of the straight line distance between the second pusher 133 and the first pusher 131 in the second direction satisfies the following relationship: when the first rolled needle body which is pulled out reaches the preset position, the second pushing piece 133 synchronously moves to the upper side of the right side of the end plate of the second rolled needle body, at the moment, the position switching mechanism 110 drives the first moving part 111 to move downwards, the second pushing piece 133 synchronously moves downwards to abut against the side face of the end plate of the second rolled needle body, and when the second moving part 121 continuously slides, the second pushing piece 133 can pull out the second rolled needle body outwards, so that the rolled needle in the rolled needle group can be pulled out.
