Pneumatic scissors and selvage folding device used in medium width loom

Abstract

The invention discloses a pneumatic scissors and selvage folding device used in a medium width loom. The pneumatic scissors and selvage folding device comprises two end part units and a middle unit, wherein the two end part units are of a same structure and are symmetrically arranged on a reed part; the middle unit is positioned between the two end part units; the end part units comprise first scissors bases and first scissors modules; the middle unit comprises a second scissors base and a second scissors module; first scissors modules are arranged on the outer sides of the first scissors bases; the second scissors module is arranged on one side of the second scissors base; the first scissors module and the second scissors module are of a same structure; first folding blocks for bending cut line ends inwards are arranged on the inner sides of the two first scissors bases; and second folding blocks for bending the cut line ends to two sides are respectively arranged on two sides of the second scissors bases. As the scissors and the selvage folding device are integrated together and mounted on the reed part, a steel reed does not need to be cut when the cloth width is changed, the reed width universality is improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a pneumatic scissors and a tuck-in device applied to a middle-width loom. Background technique [0002] At present, the scissors and the folding device of the loom on the market mainly have the following problems: [0003] First, most of them adopt two schemes of mechanical mechanism or electronic structure. These two schemes contain many mechanical parts, complex structures, and are not easy to assemble and debug. [0004] Thirdly, at present, most of the fold-in device and the scissors device adopt a split structure, that is, the two completely independent devices are installed on the loom separately, and then the matching position between the two is adjusted. This kind of scheme has a complicated structure. There are many types of components, high cost, and difficult installation and debugging. [0005] Third, for the middle framing loom, when it is necessary to ch...

[0003] First, most of them adopt two schemes of mechanical mechanism or electronic structure. These two schemes contain many mechanical parts, complex structures, and are not easy to assemble and debug.

[0004] Thirdly, at present, most of the fold-in device and the scissors device adopt a split structure, that is, the two completely independent devices are installed on the loom separately, and then the matching position between the two is adjusted. This kind of scheme has a complicated structure. There are many types of components, high cost, and difficult installation and debugging

And because the reed of the traditional loom is in a relative rotational motion relationship with the scissors and the tuck-in device, after the scissors and the tuck-in device are adjusted, during the reciprocating movement of the reed, the reed will inevitably be in the same position as the adjusted one. The scissors and the tuck-in device interfere. In order to avoid this phenomenon, the reed must be cut off to keep a certain distance between the reed and the tuck-in device. Therefore, one set is required for each cloth type. Matching the corresponding reed models will not only increase the equipment cost, but also the adjustment process is quite cumbersome, which seriously affects the production efficiency and brings a lot of inconvenience to customers
