Embodiment Construction
[0017] Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.
[0018] The weft insertion mechanism driven by the curved groove shown in the accompanying drawings includes a box body and a sword pulley 52 installed on the box body for driving the weft insertion sword belt 51; Slot mechanism and rocker mechanism.
[0019] Described box body is made up of front box body 12 and rear box body 11 (referring to figure 1 ), all be shaped on some mounting holes on the front casing and the rear casing, and the rotating shaft is all installed in the mounting holes by bearing 31. The rotating shaft includes a main shaft 41, a balance shaft 42, and a pinion shaft 43, and the axes of these rotating shafts are arranged parallel to each other.
[0020] The curved groove mechanism includes a curved groove plate positioned in the box so that it can slide laterally (the sliding direction is parallel to the axis of the aforementioned rot...

The invention relates to a curved-groove-driven wefting insertion mechanism, and aims at realizing the characteristics of high movement precision, simple structure and low manufacturing cost of the wefting insertion mechanism. According to the technical scheme, the curved-groove-driven wefting insertion mechanism comprises a box body, and a rapier belt wheel which is mounted onto the box body to drive wefting rapier belt. The curved-groove-driven wefting insertion mechanism is characterized in that a curved groove mechanism and a rocking bar mechanism which are sequentially driven through a main shaft are mounted to the box body; the curved groove mechanism comprises a curved groove board and a crank chute mechanism, wherein the curved groove board can be transversely glidingly positioned into the box body through a sliding structure, and while the crank chute structure is used for transferring the power of the main shaft to the curved groove board; the rocking bar mechanism comprises a gear set which drives the rapier belt wheel, a rocking bar which drives the gear set to move by reciprocating, and a connecting rod of which two ends are respectively hinged with the curved groove board and the rocking bar.
Description
technical field [0001] The invention relates to a textile machine, in particular to a weft insertion mechanism driven by a curved groove, which is mainly used for weft insertion of a rapier loom. Background technique [0002] The weft insertion mechanism is one of the core components of the rapier loom, and has high requirements on the motion characteristics. The existing weft insertion mechanisms can be divided into conjugate cam weft insertion mechanisms, spatial four-bar linkage weft insertion mechanisms, variable pitch Weft insertion mechanism, and electronic weft insertion mechanism. Among them, the structure of the conjugate cam weft insertion mechanism is complex and difficult to manufacture; the movement law of the rapier head of the space four-bar mechanism is not ideal, and it is difficult to adjust; although the structure of the variable pitch weft insertion mechanism is simple, the movement accuracy is not high, and high precision cannot be achieved. Weft insert...
