Description
Technical Field
The invention belongs to the technical field of textile equipment, and particularly relates to an anti-protruding edge folding mechanism.
Background
The processing of natural or chemical fibers into textile products by a textile machine requires various mechanical devices, while a bobbin is an indispensable auxiliary component of the spinning machine, which is used for winding spun yarn, the yarn is wound on the bobbin by a winding device, as shown in fig. 7, which is a schematic diagram of the yarn on the bobbin after winding, after the yarn is tightly wound on the bobbin, both ends of a yarn layer are inclined, the inclined edges of both ends form a triangular yarn layer, which is collectively called as a edging in the textile industry, for preventing the yarn at both ends from falling loose during the winding process or during the transportation process; as shown in FIG. 8, the existing edge trimming mechanism is composed of an adjusting screw, a screw fixing sleeve and a swinging support rod, wherein the upper end of the adjusting screw is provided with an adjusting knob, an internal thread is arranged in the screw fixing sleeve, the internal thread is matched with the external thread of the adjusting screw, the screw fixing sleeve is arranged on the adjusting screw, the outer side of the screw fixing sleeve is fixed on a machine body of the existing edge trimming mechanism, the swinging support rod is of a lever structure, the middle lower part of the swinging support rod is provided with a swinging support point, the left end of the swinging support rod is provided with a contact block, the right end of the swinging support rod is tilted upwards and is movably connected with the lower end of the adjusting screw, when a debugging worker is about to adjust the edge trimming size of the edge trimming mechanism, the adjusting knob is manually rotated to drive the adjusting screw, the adjusting screw is enabled to feed downwards through the screw fixing sleeve, and then the right end of the swinging support rod is enabled to move downwards, so that the left end of the swinging support rod moves upwards. Because a plurality of winding mechanisms are arranged on a large yarn winding device, workers can manually adjust the edging mechanisms for each winding mechanism, the production efficiency is reduced, the manual adjustment cannot be unified, the edging size of each edging mechanism is different, when the edging of the yarn layers is different, the tension of the yarns on each bobbin is different, when the yarns are dyed in the later stage, under the same dyeing time, the dyes on the yarn layers with the tight tension are difficult to enter the inner layer due to the different tension of the yarns, and the dyes on the yarn layers with the tension of Zhang Lisong quickly enter the inner layer, so that the dyeing of the yarn bobbins with the same batch is uneven. Therefore, the existing edge trimming mechanism has poor independence and poor consistency, and the structure is complex, and once the machining size of a certain part is in error, the later adjustment of an adjustment worker is difficult.
