Technical Field

The invention relates to the technical field of rapier looms, in particular to a heald frame shifting structure convenient for warp thread penetration.

Background

The rapier loom is the most widely used shuttleless loom at present, and has the characteristics of high speed, high automation degree and high-efficiency production of the shuttleless loom, and besides, the positive weft insertion mode has strong variety adaptability, can adapt to the weft insertion of various yarns, and has obvious advantages.

When the rapier loom in the prior art is used, each yarn needs to be drafted first. On some rapier looms, the distance between two heald frames is relatively close, which can affect the heald-penetrating process, thereby reducing the working efficiency.

Disclosure of Invention

The invention aims to provide a heald frame shifting structure facilitating warp thread penetration.

The technical purpose of the invention is realized by the following technical scheme: the heald frame shifting structure convenient for warp threads to penetrate through comprises a rack, wherein two heald frames are arranged on the rack, a fixed plate is vertically arranged on the inner side of the rack, a transverse groove is formed in the fixed plate, two extending plates are arranged on the transverse groove, and springs which are respectively abutted to the outer sides of the fixed plate are arranged at the two ends of the transverse groove; the heald frame comprises an upper crossbeam and a lower crossbeam, clamping strips are arranged on two sides of two ends of each crossbeam, an extension plate is abutted against the clamping strips which are relatively close to the outside, and limiting hooks are arranged on the extension plate and hooked on the clamping strips on the other side; the fixed plate is provided with a retainer, the retainer is provided with an expansion head which slides in the vertical direction, and the lower end of the expansion head intermittently abuts between the cross beams.

Further setting the following steps: the expansion head is internally provided with rotating teeth, both sides of the expansion head are provided with through holes, racks meshed with the rotating teeth are arranged in the through holes, and rotating handles extend outwards on the rotating teeth.

Further setting the following steps: at least two racks are arranged in the vertical direction, a connecting rod is arranged between the racks, and a moving groove for the connecting rod to move is arranged in the expansion head.

Further setting the following steps: the retainer is provided with a limit rail, the expansion head slides on the limit rail, the fixing plate is provided with a strip-shaped vertical rail, and the rotating handle extends out of the vertical rail.

Further setting the following steps: the rotation handle slides relative to the rotation wheel, a strip-shaped limiting block is arranged at the front end of the rotation handle, and the length of the limiting block is larger than the thickness of the rotation wheel.

In conclusion, the invention has the following beneficial effects: through setting up the extension board, can realize the effect of strutting to the nearer heald frame of distance to reduce the drafting process and produce the influence, guaranteed work efficiency.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Make things convenient for 2 toggle structures of heald frame that warp wore to establish, including rapier weaving machine's frame 1, be provided with two heald frames 2 in rapier weaving machine's frame 1, heald frame 2 receives the control of original mechanism of rapier weaving machine to move on vertical direction.

The equal vertical fixed plate 3 that is provided with in both sides inboard of frame 1 fixes through the connecting axle between fixed plate 3 and the frame 1, and the below position on the fixed plate 3 is provided with transverse groove 4, and transverse groove 4's both ends all are provided with inside spring 6. Extension plates 5 are arranged on two sides of the transverse groove 4, and the springs 6 are abutted against the extension plates 5 from the opposite outer sides of the two extension plates 5.

The heald frame 2 comprises an upper cross beam 7 and a lower cross beam 7, a plurality of vertical healds are arranged between the two cross beams 7, clamping strips 8 are arranged on the outer sides of two ends of the upper cross beam 7 and the lower cross beam 7, and the clamping strips 8 clamp the cross beams 7 from two sides and are fixed at the upper position and the lower position through screws. Extension board 5 supports on the centre gripping strip 8 in relative outside, is provided with restriction hook 9 on the extension board 5, and restriction hook 9 colludes on the centre gripping strip 8 of opposite side to fix 8 interlude of centre gripping strip, increase stability.

The fixing plate 3 is provided with a retainer 10, the retainer 10 is provided with a vertical limiting rail 18, and the limiting rail 18 is provided with an expansion head 11 in a vertical sliding manner. The fixing plate 3 is provided with a vertical rail 19 coinciding with the limit rail 18. The rotating teeth 12 are arranged below the expansion head 11, the two sides of the expansion head are provided with through holes 13, racks 14 meshed with the rotating teeth 12 penetrate through the through holes 13, the racks 14 face the two sides respectively, the racks 14 on the same side are preferably arranged up and down, and the racks 14 are connected through a connecting rod 16 to increase reliability. The lower end of the expansion head 11 is provided with a trapezoidal end part which can facilitate the downward entering of the expansion head 11 between the two extension plates 5, thereby facilitating the expansion of the heald frame 2.

The rotating handle 15 is arranged on one side of the rotating tooth 12, the front end of the rotating handle 15 is provided with a strip-shaped limiting block 20, the length of the limiting block 20 is larger than the thickness of the rotating wheel, the rotating handle 15 can move inwards, and therefore the rotating handle 15 is clamped in the vertical rail 19 and is kept stable.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
