Eccentric driving mechanism for griffe of jacquard

Abstract

The invention discloses an eccentric driving mechanism for a griffe of a jacquard. The eccentric driving mechanism comprises an eccentric wheel, a driving shaft, a first rotating roll, a second rotating roll and a travelling locking mechanism, wherein the first rotating roll and the second rotating roll are respectively mounted on the upper and lower sides of the eccentric wheel; an eccentric holeis formed in the eccentric wheel; the travelling locking mechanism comprises a positioning screw and two locking nuts; the positioning screw is mounted in the eccentric hole; the two ends of the positioning screw are fixed at the two ends of the eccentric hole; the two locking nuts are connected with the two ends of the positioning screw through threads; the driving shaft penetrates through the eccentric hole; the driving shaft penetrates through the positioning screw through a penetrating hole in the side part; the two locking nuts are propped against the side part of the driving shaft and lock the side part of the driving shaft. The eccentric driving mechanism adjusts the eccentric position by adjusting the position of the driving shaft on the positioning screw, so as to achieve the purpose of adjusting the eccentric amplitude.

Description

Technical field [0001] The invention relates to an eccentric drive mechanism of a jacquard machine. Background technique [0002] At present, the lifting knife of the jacquard machine is generally driven by an eccentric drive mechanism. The eccentric structure of the eccentric wheel drives the rocker arm to move, thereby driving the lifting knife to swing up and down. However, in the existing structure, the swing amplitude of the eccentric wheel cannot be adjusted. , It can only be adjusted by replacing eccentric wheels of different specifications. The replacement of eccentric wheels requires complicated disassembly procedures. If the eccentricity of an eccentric wheel can be adjusted, it can solve a large disassembly and replacement problem, improve work efficiency, and use more flexible. Summary of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the problem solved by the present invention is to provide a jacquard knife eccentric drive mechani...

[0002] At present, the lifting knife of the jacquard machine is generally driven by an eccentric drive mechanism, and the eccentric structure of the eccentric wheel drives the rocker to move, thereby driving the lifting knife to swing up and down. However, in the existing structure, the swing range of the eccentric wheel cannot be adjusted. , can only be adjusted by replacing the eccentric wheel of different specifications, and the replacement of the eccentric wheel requires a complicated disassembly process. If the eccentric range of an eccentric wheel can be adjusted, it can solve a large problem of disassembly and replacement, improve work efficiency, and use more flexibly
