In the working process, the needle jack on the needle selection rod needs to be lifted, and the existing needle selection piece is thin, so that the needle jack is easy to laterally move when being lifted, the needle jack can slide to the side edge of the needle selection piece, the needle jack is not completely lifted, the stitch is not lifted, the needle selection failure is caused, and the knitting effect is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a select needle stick, this project organization is ingenious, and solution jack that can be fine takes place to incline and moves, leads to the problem that the jack is not lifted up completely, guarantees that this department weaves and goes on smoothly, improves and weaves the quality.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a needle selection stick comprises a cylindrical stick, the cylindrical stick is tangentially fixed in a transverse groove of a roller, a plurality of needle selection pieces are arranged on the cylindrical stick according to needle selection requirements, and the needle selection pieces are positioned in a needle selection groove of the roller; the upper end of the needle selection piece is provided with a thickened extension part which is used for ensuring that the needle jack can still be completely lifted by the selected needle piece when the needle jack laterally moves.
The two sides of the upper end of the needle selection piece are respectively provided with an extension part.
The total length of the upper end of the needle selection piece and the extension part is larger than the width of the needle selection groove.
The extension length of the extension part is 0.3-1 mm.
The lower end of the needle selection piece is provided with an opening, and the needle selection piece is installed in a matched mode with the cylindrical rod through the opening.
The opening comprises a round hole and a through groove, the needle selection piece is matched with the cylindrical rod through the round hole to realize installation, and the through groove is connected with the round hole.
The width of the connecting end of the through groove and the round hole is smaller than that of the other end of the through groove; the width of the through groove is gradually enlarged from the connecting end of the through groove and the round hole downwards.
The utility model discloses following beneficial effect has:
a needle selection rod comprises a cylindrical rod, the cylindrical rod is tangentially fixed in a transverse groove of a roller, a plurality of needle selection pieces are arranged on the cylindrical rod according to the needle selection requirement, the needle selection pieces are positioned in the needle selection grooves of the roller, and a selected needle piece is lifted when a needle jack passes through the needle selection piece, so that needle selection is realized; the upper end of the needle selection piece is provided with a thickened extension part which is used for ensuring that the needle jack can still be completely lifted by the needle selection piece when the needle jack laterally moves; this project organization is ingenious, and solution needle jack that can be fine takes place the side and moves, leads to the problem that the needle jack did not lift up completely, guarantees that this department weaves and goes on smoothly, improves and weaves the quality.
