Description
Technical Field
The utility model belongs to weaving device field, concretely relates to weaving discontinuous seersucker fabric's intermittent type let-off motion for loom.
Background
In the weaving principle, the seersucker fabric needs to adopt double-shaft weaving, namely a large warp let-off quantity, a bubble shaft for foaming wrinkles and a ground shaft with a normal warp let-off quantity. The foam warp beam having a large warp let-off amount is used as a foam wrinkle by a length of warp yarn fed out more than that of the warp beam.
In the weaving process of the seersucker fabric, the traditional mechanical seersucker warp beam let-off mechanism adopts a ratchet wheel and pawl (support head) type let-off mechanism to actively drive a seersucker beam to let off seersucker warp.
Except for the foaming area, the non-foaming area for weaving decoration can be designed, so that the surface of the fabric is fluctuated and has more stereoscopic impression. When the warp is not foamed, the bubble beam let-off mechanism is required to stop the active let-off and keep the synchronous let-off with the ground warp beam. When the active let-off needs to be stopped, the pawl (expanding head) is controlled to lift, the expanding action is not generated on the ratchet wheel, so that the active transmission action of the ratchet wheel on the foam warp beam through the transmission mechanism is stopped, at the moment, the delivery of the foam warp is dependent on the coiling motion of a coiling roller of a weaving machine, the foam warp beam is dragged to be passively unwound by the foam warp beam and delivered out, the warp with the same length is delivered out in synchronization with the warp delivered by the ground warp beam, at the moment, no foaming and wrinkling are generated in a non-foaming area until the non-foaming area is finished and enters a foaming and wrinkling area, the pawl (expanding head) is controlled to fall down, the expanding action is generated on the ratchet wheel again, so that the positive transmission action of the ratchet wheel on the foam warp beam is recovered through the transmission mechanism, and the delivery amount of. However, the let-off method of the ratchet wheel and the pawl generates impact abrasion due to the supporting action of the pawl on the ratchet wheel, and is not suitable for a high-speed loom.
In addition to the ratchet-pawl bubble let-off mode, there is a servo motor let-off mode.

At the position of a guide rod 12 of a warp stop frame, the warp yarns are converged into a warp sheet 13 together with the ground warp beam 11 which rotates anticlockwise and is unwound from the ground warp beam 10, the warp yarns are divided into an upper layer and a lower layer by warp heald frames 14 and 14' to form a shed, and then the shed fabric 15 with the crinkle effect is formed by weft insertion, beating-up and reeling.
When the toothless area II of the interrupted toothed belt rotates anticlockwise to the outer teeth of the toothed belt 3 with the through teeth, the toothless area can not drive the toothed wheel 4 to rotate and drive the foam warp beam to rotate actively, the foam warp beam 9 is sent out, the foam warp beam can only depend on the dragging of the winding roller 16 of the fabric 15, the foam warp beam unwinds passively to release warp, and the speed is synchronous with the ground warp.
