Automatic drawing-off auxiliary detection device for yarns

Abstract

The invention relates to the technical field of yarn textile machinery, in particular to an automatic drawing-off auxiliary detection device for yarns. The automatic yarn drawing-off auxiliary detection device comprises a machine frame, wire conveying rollers, wire pressing devices, a driving device, a tensioning device, a connecting rod groove wheel, a groove wheel frame and a clutch device, wherein the left end and the right end of the machine frame are fixedly connected with the wire conveying rollers respectively, the left end and the right end of the machine frame are fixedly connected with the wire pressing devices respectively, the two wire pressing devices are located on the inner sides of the two wire conveying rollers, the tensioning device is arranged at the middle end of the machine frame, the driving device is fixedly connected to the machine frame, the connecting rod groove wheel is in clearance fit with the groove wheel frame, the groove wheel frame is fixedly connectedto the machine frame, the connecting rod groove wheel is fixedly connected to one end of the clutch device, and the other end of the clutch device is fixedly connected with the driving device. According to the automatic drawing-off auxiliary detection device, automatic take-up tensioning can be realized when the yarns are separated, the yarn pressing devices can achieve clamping and fixing the yarns when the yarns break or fall off from the tensioning device, and the yarns are prevented from being drawn off.

Description

technical field [0001] The invention relates to the technical field of yarn textile machinery, in particular to an auxiliary detection device for automatic yarn extraction. Background technique [0002] The existing patent application number is a yarn tensioner (T) of CN201110034641.5, the yarn tensioner includes a series of rigid yarn deflection elements (1), and these yarn deflection elements jointly determine the yarn path (P), the yarn deflecting elements are spaced apart in the middle on opposite sides of the yarn path, so that a corresponding yarn deflecting element is arranged on one side and makes it relative to the yarn arranged on the opposite side The deflection elements (1) are offset in the direction of yarn travel (D), at least one of the yarn deflection elements (2a, 2b) can be adjusted substantially perpendicular to the To change the tensioning effect, the yarn path (P) consists of at least one thin-walled flexible spring leaf (8a, 8b) on each side of the ya...
