Framing scissors device for air jet loom

Abstract

A width division scissors device of an air jet loom is used for automatic width division of double-width fabric of the air jet loom. A driving wheel, a transmission wheel and a driven wheel which are meshed are fixed in a scissors box. A fixed scissors sheet is fixed at the side edge of the scissors box. A driving scissors sheet extends out of the side face of the scissors box, is fixed in the scissors box through a rotary shaft of the driving scissors sheet, and forms a scissors mouth together with the fixed scissors sheet. Special-shaped teeth on the driven wheel are meshed with the driving scissors sheet. The lower end of a return spring is fixed to a return spring hook on the driving scissors sheet; the upper end of the return spring is fixed to a return spring fixing pin on the scissors box. The scissors box is connected with a sliding base which is installed in a sliding groove of a fixed base. The fixed base is connected with the air jet loom. According to the width division scissors device of the air jet loom, no specially-assigned person needs to carry out manual width division; by the use of width division scissors special for the air jet loom, automatic width division of the double-width fabric can be completed on the air jet loom, the position of the scissors can be adjusted flexibly, length of rough selvedges is controlled, and the width division scissors device of the air jet loom has the advantages of being high in working efficiency, small in size, low in cost and the like.

Description

technical field [0001] The invention relates to the technical field of textile production and weaving, in particular to a special framing scissors device for an air-jet loom. Background technique [0002] At present, when the air-jet loom weaves double-width varieties, it lacks special framing scissors, and the double-width fabric cannot be automatically cut from the middle on the loom. Instead, the two fabric widths need to be transported to the next post-finishing process. Scissors slowly separate the two panels by hand. Its disadvantages are: 1. The operation of double-width cloth cutting is performed by a special person, which wastes manpower and material resources; 2. The middle line of the double-width cloth that is manually separated is not straight, and there are a lot of rough edges. The length of the width is long or short, and the quality cannot be controlled. ; 3, the work is time-consuming and labor-intensive, and the work efficiency is extremely low. Content...

[0002] At present, when the air-jet loom weaves double-width varieties, it lacks special framing scissors, and the double-width fabric cannot be automatically cut from the middle on the loom. Instead, the two fabric widths need to be transported to the next finishing process for special personnel to use. Scissors slowly separate the two fabrics by hand

Its disadvantages are: 1. The operation of double-width cloth cutting is performed by a special person, which wastes manpower and material resources; 2. The middle line of the double-width cloth that is manually separated is not straight, and there are a lot of burrs. The length of the width is long or short, and the quality cannot be controlled. ; 3. The work is time-consuming and labor-intensive, and the work efficiency is extremely low
