A weaving shedding device for a loom

Abstract

The invention discloses a cross woven opening device of a weaving machine. The cross woven opening device comprises a heald frame mechanism, a driving device, a guide mechanism and a transmission mechanism as well as a heald frame upper beam and a heald frame lower beam, wherein the heald frame upper beam comprises a first upper heald frame and a second upper heald frame; the heald frame lower beam comprises a first lower heald frame and a second lower heald frame; the first upper heald frame and the first lower heald frame are positioned in a same vertical plane; the second upper heald frame and the second lower heald frame are positioned in a same vertical plane; multiple first cross woven reeds are transversely and uniformly arranged between the first upper heald frame and the first lower heald frame; multiple second cross woven reeds opposite to the first cross woven reeds are transversely and uniformly arranged between the second upper heald frame and the second lower heald frame; the first cross woven reeds and the second cross woven reeds comprise upper reed beams and lower reed beams; multiple sheet full reed teeth are formed between the upper reed beams and the lower reed beams; a semi-reed tooth is arranged between each two adjacent full reed teeth. According to the invention, high-speed operation is promoted, the staggered motion time of warp yarns is short, the weft insertion time can be increased, weft insertion is promoted, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of textile machinery, in particular to a weaving shedding device for a loom. Background technique [0002] Twisted fabrics such as screens, industrial twisted fabrics, etc. are special fabrics, such as attached figure 1 As shown, among them, the horizontal ones are the weft yarns, and the vertical ones are the warp yarns. One layer of warp yarns is always on the upper layer of the fabric, and the other layer of warp yarns is always on the lower layer. The warp yarns form crossings between adjacent two weft yarns. The positions are exchanged one weft and one weft. The existing twisted fabrics are mostly woven on rapier looms. Most of the shedding devices adopt the method of leno twisted healds or needle row. The loom speed is low and the mesh density range is suitable It is small, easy to make mistakes, and has many wearing parts, which cannot meet the user's requirements for high-speed, high-efficiency, and high-qual...
