Abstract
The invention provides a closed type special-shaped reed which comprises a special-shaped reed body arranged in an upper beam and a lower beam. An upper reed strip, a half-arc reed groove piece and a lower reed strip are arranged on the special-shaped reed body from top to bottom. The two ends of the reed groove piece are connected with the lower end of the upper reed strip and the upper end of the lower reed strip through thin elastic strips respectively. The reed groove piece and the thin elastic strips form a reed groove used for passing weft yarns, and pushing components are arranged in the upper beam and the lower beam and used for controlling the upper reed strip and the lower reed strip to move synchronously and relatively. The pushing components push the upper reed strip and the lower reed strip to synchronously and relatively move when each air jetting action of an air jet loom starts. A notch of the reed groove formed by the reed groove piece and the thin elastic strips becomes narrow under the extrusion of the upper reed strip and the lower reed strip, and therefore airflows are not prone to being diffused when passing through the reed groove.
Description
Affiliated technical field
The present invention relates to air-jet loom field, especially, is a kind of closed Profiled Reed that is applicable to air-jet loom.
Background technology
Pneumatic picking mechanism mainly comprises main burner and pilot jet, anti-airflow diffuser, air supply system.Anti-airflow diffuser mainly contains two kinds, and one is confuser, and another kind is special-shaped reed.Confuser composition pipeline, between confuser, to leave gap to hold warp thread, at the de-yarn groove of radially having of confuser, to complete after wefting insertion, weft yarn is deviate to stay in shed open from pipeline, the opening portion of confuser top, after completing for wefting insertion, weft yarn de-yarn groove from confuser is deviate from and stays in shed open.The anti-air-flow diffusion effect of confuser is good, but warp thread is disturbed and weighed, and sley sweep is large, is unfavorable at a high speed, therefore on novel air injection loom, all adopting the anti-airflow diffuser of special-shaped reed.
Special-shaped reed also claims groove reed, and main burner is aimed at reed groove, and the air-flow weft traction of ejection passes through shed open in the groove of this special dent.Therefore, when wefting insertion, reed groove must be positioned at shed open central authorities, and fell contacts reed groove top when beating up, weft yarn is by the fell of hitting the person, the pipeline of the anti-air-flow diffusion effect of the obvious special-shaped reed confuser composition more not as good as sealing, but can adapt to the weaving of high sley fabric, and for weaving machine high-speed provides may.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of closed Profiled Reed, this closed Profiled Reed can improve the anti-air-flow diffusion of Profiled Reed.
The technical solution adopted for the present invention to solve the technical problems is:
This closed Profiled Reed comprises the Profiled Reed being arranged in lower and upper cross-member, described Profiled Reed is divided into reed bar from top to bottom, be reed slotted vane and the lower reed bar of half arc, described reed slotted vane two ends are connected with the upper end of described lower reed bar with the lower end of described upper reed bar respectively by thin spring, described reed slotted vane and described thin spring form the reed groove that weft yarn passes through, in described lower and upper cross-member, be provided with and control described upper reed bar, the thrust member of the synchronous relative motion of lower reed bar, described thrust member when the each jet action of air-jet loom starts, promote described on reed bar, the synchronous relative motion of lower reed bar.
As preferably, described thrust member is the power transmission shaft that is separately positioned on strap cam in described lower and upper cross-member, and described power transmission shaft synchronously rotates, one end of reed bar or lower reed bar in contact corresponding to each described cam.
As preferably, the bottom of described reed slotted vane is provided with backstay, and described backstay is slidably arranged in a positioning block, is provided with the slip cavity matching with described backstay in described locating piece.
As preferably, the slip cavity in described locating piece is communicated with an air pressure and adjusts equipment.
The invention has the advantages that:
The reed groove that described reed slotted vane and described thin spring form, under the extruding of reed bar and lower reed bar, it is relatively narrow and small that the notch of reed groove becomes, and is not easy diffusion when therefore air-flow is by catching groove on described.
Accompanying drawing explanation
Fig. 1 is the structural representation of this closed Profiled Reed.
Fig. 2 is the structural representation of this closed Profiled Reed reed slotted vane.
Fig. 3 is the structural representation under this closed Profiled Reed reed groove contraction state.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In the present embodiment, consult Fig. 1 and Fig. 2, this closed Profiled Reed comprises the Profiled Reed 200 being arranged in lower and upper cross-member 500, described Profiled Reed 200 is divided into reed bar 210 from top to bottom, be reed slotted vane 300 and the lower reed bar 220 of half arc, described reed slotted vane 300 two ends are connected with the upper end of described lower reed bar 220 with the lower end of described upper reed bar 210 respectively by thin spring 320, described reed slotted vane 300 forms with described thin spring 320 the reed groove that weft yarn 10 passes through, in described lower and upper cross-member 500, be provided with and control described upper reed bar 210, the thrust member of lower reed bar 220 synchronous relative motions, described thrust member when the each jet action of air-jet loom starts, promote described on reed bar 210, the synchronous relative motion of lower reed bar 220.
Above-mentioned closed Profiled Reed, described thrust member is the power transmission shaft that is separately positioned on strap cam 510 in described lower and upper cross-member 500, described power transmission shaft synchronously rotates, one end of reed bar 210 or lower reed bar 220 in the contact of each described cam 510 correspondences, cam 510 can synchronously promote upper reed bar 210 or lower reed bar 220 accurately.
Above-mentioned closed Profiled Reed, the bottom of described reed slotted vane 300 is provided with backstay 310, described backstay 310 is slidably arranged in a positioning block 400, in described locating piece 400, be provided with the slip cavity matching with described backstay 310, described locating piece 400 can keep the position of reed slotted vane 300 not produce skew.
Above-mentioned closed Profiled Reed, slip cavity in described locating piece 400 is communicated with an air pressure and adjusts equipment, with various countries' air pressure, adjust equipment, can adjust described reed slotted vane 300 and be subject to the restriction pressure from described locating piece 400, make reed groove that described reed slotted vane 300 and described thin spring 320 form be applicable to the weft yarn 10 of unlike material.
