Edge folding-in device for gripper shuttle loom

Abstract

The invention provides an edge folding-in device for a gripper shuttle loom, and relates to the field of textile machines. The edge folding-in device comprises two parallel supporting plates and a supporting platform; the supporting platform is located above the supporting plates, the upper end of the supporting platform is provided with a sliding track, two moving trolleys are slidingly installedon the sliding track, an edge folding machine is installed at the upper end of each moving trolley, a transmission shaft is installed between the two edge folding machines, one end of the transmission shaft is rotatably connected to one edge folding machine, the other end of the transmission shaft penetrates through the moving trolley close to the right side and is rotatably installed on a transmission shaft base, crochet hooks are installed on the opposite surfaces of the two edge folding machines, the portion, at the left side of the edge folding machine at the left side, of the supportingplatform is provided with bending-type scissors, and a width adjusting device is installed at the inner sides of the supporting plates. According to the edge folding-in device, through a series of transmission mechanisms, smooth-edged fabrics of different specifications are woven; through the arrangement of the width adjusting device, the distance between the two edge folding machines is changed to adapt to fabrics of different widths; the whole device is simple in structure and high in practicability and has a good edge folding effect.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a tuck-in device for a projectile loom. Background technique [0002] With the increase of labor cost and people's improvement of textile quality, shuttleless looms are generally equipped with folding-in devices to produce smooth-edged fabrics. It is quite common in China to install hemming devices on shuttleless looms to produce ordinary one-weft-folded smooth-edged fabrics, and the technology is relatively mature. But like some special fabrics that need two or three wefts to be folded in at a time, such as towels. At present, among the domestic towel enterprises, only Standard Textile is making smooth-edged towels normally, and the rest are not in normal production. Therefore, the tuck-in technology of fabrics such as towels is almost blank in China. This requires the tuck-in device to be able to meet the requirements for tuck-in of different fabric selvedges, realize one-we...

Problems solved by technology

[0003] Due to the special structure of the weft insertion mechanism in the weaving process of popular shuttleless looms, the selvedges are raw edges, which cannot form natural selvedges in the process of weft insertion like shuttle looms, which affects the effect of textile fabrics, especially Decorative fabrics are more prominent, and post-processing such as cutting, hemming, and sewing is required, which is labor-intensive and time-consuming, and wastes a lot of raw materials

Although imported high-end shuttleless looms use folding devices, due to their complex structure and very expensive equipment, it is often difficult to popularize and apply them due to financial reasons.
