Description

Yarn tension control device for doubling winder

Technical Field

The utility model relates to a doubling equipment technical field, concretely relates to yarn tension control device for doubling winder.

Background

With the wide popularity of high-count and high-density fabrics, the multi-jet technology is also popularized in a plurality of weaving factories, the premise of multi-jet is that a plurality of weft yarns are required to be fed into a weaving opening together, and most enterprises select to pass a single cone yarn through a doubling machine and combine the single cone yarn into two or more cone yarns as the weft yarns, so that the weaving efficiency is improved, and the weaving defects are reduced. However, the larger the number of yarns to be combined in the doubling winder, the larger the difference in yarn count, and particularly in the case of combining yarns and yarns, the difference in tension of individual single yarns occurs, resulting in non-uniform yarn combination, and a large number of defects such as weft shrinkage and small braids occur in the subsequent process, both weaving and double twisting. The reason for the single yarn tension inconsistency is often generated on a tension control device of a doubling winder, most of the tension control devices of the doubling winder at present adopt a tray type tension control device, the device generally controls the yarn tension by using the weight of a pressing sheet above the device or the elastic force of a spring, but in the actual production of the device, especially yarns with high hairiness and filaments with oil agents, if the cleaning is not in place, the flyings can be gathered in the middle of the tension control sheet, so that the tension control is invalid, and finally the phenomenon of the inconsistent doubling is generated.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, a yarn tension control device for a doubling winder, which comprises a controller 1, a data bus 2, a plurality of units, wherein the data bus 2 is connected with the controller 1, the units comprise a direct current brushless motor 3, a tension sensor 7, a machine body control panel 5, a tension motor 8, a stepping drive plate 6, a filament cutter 9, a plurality of cone yarns 11, the filament cutter 9, the tension motor 8 and the tension sensor 7 are sequentially arranged along the advancing direction of yarns 12, a grooved drum 4 is connected on a motor shaft of the direct current brushless motor 3, the input end of the machine body control panel 5 is connected with the tension sensor 7, the output end of the machine body control panel 5 is connected with the data bus 2, and the input end of the machine body control panel 5 is connected with the data bus 2.

The unit also comprises yarn detectors 10, the number of the yarn detectors 10 is equal to that of the cone yarns 11, and the yarn detectors 10 are correspondingly arranged with the cone yarns 11. The yarn detector 10 is arranged corresponding to the bobbin yarn 11 and used for detecting the conditions of yarn breakage or winding ending of the yarn 12 and the like, and the problems of single yarn or strand missing and the like in production are avoided.

Three cone yarns 11 and three yarn detectors 10 are arranged.

The controller 1 is provided with a display for displaying the tension condition of the yarn 12 in each unit, so that the working personnel can know the running state of the units more intuitively and can perform manual intervention if necessary.

In specific implementation, a plurality of yarns 12 on the cone yarn 11 are combined and wound on the grooved drum 4 driven by the direct current brushless motor 3 through the filament cutter 9, the tension motor 8 and the tension sensor 7, and the tension of the yarns 12 in the process is controlled by the rotating speed of the tension motor 8.
