Description

A kind of variable Profiled Reed

Technical field

The utility model relates to air-jet loom apparatus field, especially, is a kind of variable Profiled Reed for air-jet loom.

Background technology

Air-jet loom is to adopt jet-stream wind weft traction to pass through the shuttleless loom of shed open.Operation principle is to utilize air as wefting insertion medium, with the compressed air stream ejecting, weft yarn is produced to frictional traction and draws, and weft yarn band is crossed to shed open, reaches the object of wefting insertion by the jet of jet generation.This filling insertion way can make loom realize high speed high yield.In several shuttleless looms, air-jet loom is the highest a kind of of the speed of a motor vehicle, because filling insertion way is reasonable, enter latitude rate higher, running operation handy and safe, has varietal adaptation wider, machine material consumption is few, the advantages such as efficiency is high, and the speed of a motor vehicle is high, noise is low, have become one of Novel cloth machine of tool development prospect.

Air-jet loom abnormity Profiled Reed makes wefting insertion and the vitals beating up in weaving process, its life-span and operating condition are directly connected to loom efficiency and fabric quality, prolongation along with the duration of runs on Profiled Reed machine, abrasion condition progressively increases, reed trench bottom and weft yarn contact area is less causes when this beats up due to Profiled Reed, same weft yarn, because each reed groove active force point-like distributes, can make weft yarn unbalance stress, causes weft yarn to enter latitude too loose.

Utility model content

In order to address the above problem, the purpose of this utility model is to provide a kind of variable Profiled Reed, and this variable Profiled Reed makes weft yarn stressed evenly when can prevent reed trench bottom Fast Wearing.

The utility model solves the technical scheme that its technical problem adopts:

This variable Profiled Reed comprises the Profiled Reed being arranged on entablature and sill, and described Profiled Reed comprises the reed groove beating up, and the bottom land of described reed groove is provided with the member that can broaden, and the direction that broadens of the described member that broadens parallels with the weft yarn that need beat up.

As preferably, the described member that broadens comprises two horizontal stripes arranged side by side, and one end of described horizontal stripe is articulated in respectively the bottom land of described reed groove, and the other end of described horizontal stripe is provided with to be controlled described horizontal stripe and merge separated magnet.

As preferably, one of described magnet is that one of electromagnet is permanent magnet, and described electromagnet can change switching pole orientation.

In another is preferred, described magnet is the permanent magnet that magnetic pole is identical, and the opposite side of described reed groove bottom land is provided with the magnetic stripe same with described permanent magnet Magnetic Phase, and described magnetic stripe is parallel with described weft yarn.

The utility model has the advantage of:

By the member that can broaden, increase Profiled Reed and when beating up, act on the wearing and tearing that active area on weft yarn reduces Profiled Reed, weft yarn is stressed evenly simultaneously.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated:

Embodiment mono-:

In the present embodiment, consult Fig. 1, this variable Profiled Reed comprises the Profiled Reed 100 being arranged on entablature 150 and sill 160, described Profiled Reed 100 comprises the reed groove 110 beating up, the bottom land of described reed groove 110 is provided with the member 120 that can broaden, the direction that broadens of the described member 120 that broadens parallels with the weft yarn 20 that need beat up, in the shed open that described weft yarn 20 interweaves at warp thread 10.

Consult Fig. 2, the described member 120 that broadens comprises two horizontal stripes arranged side by side 300, and one end of described horizontal stripe 300 is articulated in respectively the bottom land of described reed groove 110, and the other end of described horizontal stripe 300 is provided with the described horizontal stripe of control and merges separated magnet 310.

Above-mentioned variable Profiled Reed, 310 1 of described magnets are that one of electromagnet is permanent magnet, described electromagnet can change switching pole orientation, by controlling the magnetic of electromagnet, make Profiled Reed 100 separated horizontal stripe 300(electromagnet when beating up identical with permanent magnet pole), when non-beating up, make Profiled Reed 100 when beating up, merge horizontal stripe 300(electromagnet contrary with permanent magnet pole).

Embodiment bis-:

In the present embodiment, consult Fig. 3, this variable Profiled Reed comprises the Profiled Reed 100 being arranged on entablature 150 and sill 160, described Profiled Reed 100 comprises the reed groove 110 beating up, the bottom land of described reed groove 110 is provided with the member 120 that can broaden, the direction that broadens of the described member 120 that broadens parallels with the weft yarn 20 that need beat up, in the shed open that described weft yarn 20 interweaves at warp thread 10.

Consult Fig. 4, the described member 120 that broadens comprises two horizontal stripes arranged side by side 300, and one end of described horizontal stripe 300 is articulated in respectively the bottom land of described reed groove 110, and the other end of described horizontal stripe 300 is provided with the described horizontal stripe of control and merges separated magnet 310.
