Problems solved by technology

However, due to the wide slit positive pressure drafting airflow and the high exit velocity of the fiber, it is easy to cause uneven laying (compared with the wide slit suction (negative pressure) drafting process); Under the action of high-speed airflow, it is arranged vertically on the lapper with less horizontal crossing, resulting in a high vertical and horizontal strength ratio of the finished nonwoven fabric, which affects product quality

Embodiment Construction

[0028] exist Figure 1 to Figure 7 In the schematic diagram of the present invention shown, the sub-filament matrix 4 is connected to the drafter through a linear bearing 5 fixed at the bottom of the drafter, and one side of the sub-filament matrix is ​​passed through the transmission mechanism 3 and the eccentric mechanism 2, frequency conversion The motor 1 is connected, and the frequency conversion motor is set on the drafting device, which drives the splitter body to move left and right. The traverse frequency is adjusted by frequency conversion, and the adjustment range is 200 times / min. The traverse amplitude is adjusted by the eccentric mechanism, and the adjustment range is 10mm. The length of the main body of the splitter is equal to the outlet of the wide slit positive pressure drafter. There are front and rear staggered slideways on the mother body of the wire splitter, and the angle between the slideway and the level of the mesh surface is 60° 0 to 100 0 , each s...

Abstract

According to a filament dividing device for a slit drawing device, a filament dividing sheet matrix is connected with the drawing device through a linear bearing fixed to the bottom of the drawing device, one side of the filament dividing sheet matrix is connected with a traversing mechanism through a transmission mechanism, and filament dividing sheets are arranged on the filament dividing sheetmatrix. According to the invention, the fiber web forming uniformity can be improved, and the longitudinal-transverse strength ratio of the product is reduced; the traverse frequency of the filament dividing device can be adjusted at will according to different varieties; the traverse width of the filament dividing device can be adjusted at will within a certain range; the filament dividing sheetmatrix is connected with the drafting device through the linear bearing fixed at the bottom end of the drafting device, so that the transverse movement is smoother and more stable; and the filament dividing sheets are independently detachable, so that the maintenance and the replacement are convenient.

Description

technical field [0001] The invention relates to the field of nonwoven fabrics, in particular to a filament separating device. Background technique [0002] At present, spunbonded nonwoven fabrics mostly use airflow drafting to achieve fiber drafting. The drafting device is mainly divided into wide slit suction (negative pressure) drafting, wide slit positive pressure drafting, and circular tube type. Three kinds of drafting. Positive pressure drawing air speed is fast, suitable for some polymers that require higher drawing speed. However, due to the wide slit positive pressure drafting airflow and the high exit velocity of the fiber, it is easy to cause uneven laying (compared with the wide slit suction (negative pressure) drafting process); Under the action of high-speed airflow, they are arranged vertically on the lapper with less horizontal crossing, resulting in a high vertical and horizontal strength ratio of the finished nonwoven fabric, which affects product quality...
