The invention belongs to the technical field of textile machinery, and specifically relates to an amplitude-variation weft-pulling device. The amplitude-variation weft-pulling device comprises a weft-pulling trolley guide machine frame and a weft-pulling trolley; the weft-pulling trolley guide machine frame includes a first supporting body, a second supporting body and a cross beam, wherein the first supporting body and the second supporting body move linearly along two parallel guide rails, and the cross beam is separately connected with the first supporting body and the second supporting body; the weft-pulling trolley moves along the cross beam, the cross beam is rotatably connected with the first supporting body, and a first movable body is movably arranged on the cross beam in the length direction. The first movable body and the second supporting body are rotatably connected; an angle adjusting device is arranged on the weft-pulling trolley and is used for adjusting the horizontalangle of the weft-pulling trolley relative to the cross beam. According to the amplitude-variation weft-pulling device, when the distance between the two guide rails is set, the angle of the cross beam relative to the two guide rails determines the moving distance and angle of the weft-pulling trolley on the cross beam, the laying length and laying angle of a weft in the moving direction are determined, different fabric structures can be obtained by changing the angles, and the flexibility of the equipment is improved.
Description
technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a variable amplitude weft pulling device. Background technique [0002] In the field of textile machinery, a group or several groups of yarns arranged in parallel are formed into loops on the left and right working needles of the warp feeding machine at the same time to form knitted fabrics. This method is called warp knitting, and the equipment used is warp knitting machine. [0003] When weaving, a number of weft yarns drawn from the weft creel are sent to the weft pulling trolley, and the weft pulling trolley is driven by the driving device to perform the weft pulling action, and the weft laying is completed with the use of the weft laying trolley. However, in current warp knitting equipment, the angle of weft laying in the longitudinal direction is fixed, that is, the angle at which the weft pulling trolley moves in the longitudinal direction is fixed. ...
