Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, it is difficult to realize automatic production due to the large number of opening layers of the 2.5 fabric in the prior art and the small number of openings of the cloth fell, and it is used as a rapier for weft insertion in the prior art. , it cannot be moved according to the height and position of the opening, so that the problem of automatic weft insertion cannot be realized; the present invention proposes a multi-layer 2.5D fabric forming opening device

Embodiment 1

[0034] A multi-layer 2.5D fabric forming opening device, including a bracket 1, the upper and lower ends of the side wall of the bracket 1 are evenly connected with a No. No. 1 slide rail 12 is slidably connected with No. 1 slide rail 12, and No. 1 electric telescopic rod 111 is fixedly connected in the No. 1 slide rail 11, and No. 1 electric telescopic rod 111 is connected with No. Fixed;

[0035] The inside of the No. 2 slide rail 12 is slidably connected to a No. 1 block 13 through the No. 2 slide block 121. There is a gap between the No. 1 block 13 and the No. 2 slide rail 12. The lower end of the No. 1 block 13 is fixedly connected with a No. 2 electric telescopic rod 131, said No. 2 electric telescopic rod 131 is slidably connected to the lower end of support 1;

[0036] A No. 1 column 132 is evenly arranged on the side of the No. 1 block 13 away from the No. 2 slide rail 12, and one end of the No. 1 post 132 passes through the No. 1 block 13 and is rotatably connected ...

Embodiment 2

[0053] The difference between the first embodiment and the second embodiment is that the transmission unit includes a motor 22, a pulley 23 and a belt 24; the motor 22 is fixedly connected to the upper end of the second block 14, and each of the first pillar One end of 132 away from the second block 14 is fixedly connected with a shaft pulley 23, and the motor 22 and the shaft pulley 23 are connected by a belt 24;

[0054] During use, the transmission unit includes a motor 22, a shaft pulley 23 and a belt 24, and the motor 22 is fixedly connected to the upper end of the second block 14, so that the end of the first column 132 away from the second block 14 is fixedly connected to the shaft pulley 23 , and the motor 22 and the shaft pulley 23 are connected by a belt 24, by controlling the rotation angle of the motor 22, the motor 22 is controlled by the belt 24 to control the rotation angle of the shaft pulley 23, thereby realizing the control of the rotation angle of the first c...

Abstract

The invention relates to the technical field of fabric forming, in particular to an opening device for multi-layer 2.5D fabric forming; Slider and No. 1 block; the central axis of the two acute angles of No. 2 block is parallel to the horizontal plane. By placing multiple layers of fabric on the upper and lower sides of No. 2 block, and by setting No. 1 slide rail and No. 2 slide rail, The No. 1 electric telescopic rod in the No. 1 slide rail is stretched, so that No. 1 drives the telescopic rod to push the two ends of the No. 2 slide rail to slide left and right inside the No. 1 slide rail at the upper and lower ends. The rod is stretched, so that the No. 1 block drives the No. 2 block and the transmission unit to slide up and down in the No. 2 slide rail, so that the No. 1 block can realize two-axis linkage in the same opening plane through the No. 1 slide rail and the No. 2 slide rail. control.

Description

technical field [0001] The invention relates to the technical field of fabric forming, in particular to a multi-layer 2.5D fabric forming opening device. Background technique [0002] The multi-layer 2.5D flat fabric woven with special fibers such as carbon fiber and quartz fiber is a fiber-reinforced prefabricated body for various composite nozzles, throat linings and combustion chambers. It has excellent properties such as high strength modulus, small thermal deformation, low density, erosion resistance and friction resistance, and is widely used in solid rocket motor nozzle ablation composite materials; [0003] But when the textile equipment multi-layer fabric in the prior art carries out weft insertion by shedding, the quantity of the weaving mouth of multi-layer 2.5D fabric weaving is particularly many, and the woven fabric of many weaving mouths in the prior art is mostly by artificial weft insertion, but due to many Layer 2.5 fabric has many layers of openings, and ...
