Description

Selvedge twisting device of textile machine

Technical Field

The utility model relates to the field of textile tools, in particular to a selvedge twister of a textile machine.

Background

The selvage is an important component of the fabric and its basic function is to lock the edge warp yarns on the outside of the fabric to prevent the edge warp yarns from slipping loose. In a traditional shuttle loom, a shuttle is used to introduce continuous weft yarns, the weft yarns pass by the outermost warp yarns on two sides of the fabric, and the weft yarns are woven with the whole warp yarns in a reciprocating manner, so that a smooth and good natural edge is formed. In the existing shuttle-free looms, the cheese which is still arranged outside the shed is adopted for weft supply, and in the weft insertion process, the weft needs to be cut according to the length of each weft (except for rapier looms which are introduced by double wefts), so that selvedges of discontinuous weft are formed on two sides of the fabric. Therefore, the shuttleless loom needs to adopt a selvedge twisting device.

In the operation process of the selvedge device of the textile machine, two pairs of opposite heddles swing up and down, and no device for preventing the heddles from falling off is arranged outside a hanging rod for hanging the heddles, so that once the heddles fall off from the selvedge device, yarn breakage can be generated, and the machine is stopped for repair; some weaving machine selvedge twister heddle hanging rods are provided with pin shafts and pin holes which are matched and fixed, the movable connection is unstable, and the pin shafts and the pin holes are easy to separate; for some heddles with different models or heddles buckled on a doup edge device, a device for preventing the heddles from falling off is arranged only at the outer side of a hanging rod for hanging the heddles, and the heddles are not stable enough; the holes of heddles of different types which are sleeved on the selvedge twister are not completely matched with the hanging rods for hanging the heddles, so that the heddles can change positions due to the swinging of the sliding blocks, and the hard heddle anti-falling device is easy to wear the heddles; the limit of the installation space of the machine is received, the replacement process of the healds and the selvedge device on the machine is difficult, and the replacement is very difficult for maintenance personnel, so that the working efficiency is reduced.

How to stabilize the harness wire in the operation process of the selvedge device, prevent the harness wire from falling off to cause the consequence of broken yarn shutdown, protect the harness wire, prevent the harness wire from being worn, facilitate the installation of the harness wire, and become a technical problem needing to be broken through.
