Problems solved by technology

[0006] The purpose of the present invention is to provide a height-difference adjustable backrest structure, which uses the difference in backrest height to solve the problem of warp yarn tension (warp let-off) to realize weft yarn bending. The method is simple, the modification of the loom is small, and the effect is obvious

Embodiment

[0056] Embodiment: The preparation of a height difference-adjustable back beam structure mainly adopts a special back beam with height-adjustable insert rods. The specific method is as follows:

[0057] (1) Preparation of the central axis of the regular hexagon:

[0058] a. Make 6 strip metal plates with the same material, shape and size as the central axis panel, including two central axis panels A 11, two central axis panels B12, two central axis panels C13, and central axis panels The length is equal to the total width of the loom, the width ranges from 10mm to 20mm, and the thickness is 3mm to 5mm.

[0059] b. Set several rectangular rod holes 14 of the same shape and size on the central axis panel along the length direction. The length of the rectangular rod holes 14 along the length direction of the central axis panel is 5mm~20mm, and the width perpendicular to the length direction is 5mm~8mm ; The rectangular rod hole 14 is located in the middle of the central axis pa...

Abstract

The invention discloses a back rest structure with adjustable height difference. The structure comprises a regularly hexagonal center shaft, a plurality of metal insertion rods and warp platforms correspondingly arranged at the two ends of each metal insertion rod one to one. The regularly hexagonal center shaft comprises two center shaft panels A, two center shaft panels B and two center shaft panels C. The two center shaft panels A, the two center shaft panels B and the two center shaft panels C are spliced in pairs oppositely to form the regularly hexagonal center shaft. Rectangular insertion rod holes identical in shape and size are formed in the two center shaft panels A, the two center shaft panels B and the two center shaft panels C in the length direction. Every two metal insertion rods are correspondingly inserted into the two corresponding symmetric rectangular insertion rod holes one to one; a plurality of round positioning holes identical in shape and size are formed in the metal insertion rods in the length direction; the metal insertion rods are fixed into the rectangular insertion rod holes through positioning lead wires. The back rest structure has the advantage that yarns on adjacent sections have tightness difference by fixing, interchanging and changing the height difference of the adjacent insertion rods.

Description

technical field [0001] The invention belongs to the technical field of weaving machinery, and in particular relates to a height difference adjustable back rest structure. Background technique [0002] The back beam of the ordinary loom is a cylinder. Under the configuration of single warp beam quantitative feeding, the tension of all warp yarns in the weaving process is basically equal within a certain small range, which can be used for weaving single structure, or structure Regular fabric with similar elastic and flat surface without special appearance. [0003] In the production of grid fabrics with large differences in structure and tightness, such as plain weave and vertical stripe fabrics with more than 8 satin weaves, it is usually necessary to switch to double warp beams and adopt the method of different let-off amounts. [0004] The seersucker fabric is a kind of appearance effect fabric with concave and convex arches in some areas and flat other areas. Usually, the...
