Automatic stop device for first time of warp-lacking of circular weaving machine

Abstract

The invention discloses an automatic stop device for the first time of warp-lacking of a circular weaving machine. The automatic stop device comprises a creel, a hanger, bobbin yarns, a detector and an annunciator, wherein the hanger is a metallic conductor and is arranged on the yarn surface of the bobbin yarns or hung on yarns between the bobbin yarns and a threading plate; when being arranged on the yarn surface of the bobbin yarns, the hanger is in contact with warps on the outer surface of the bobbin yarns, and when being hung on the yarns between the bobbin yarns and the threading plate, the hanger is in sliding contact with the yarns; and the detector is a metal bobbin or a metal warp stop piece. The automatic stop device for the first time of the warp-lacking of the circular weaving machine, disclosed by the invention, has the beneficial effects that the automatic stop device which is arranged on the creel can discover that the bobbin yarns are used up for the first time and make a stop response in time, is high in sensitivity, simple and reliable in structure and convenient to operate and can effectively overcome the tapping fault of breakage of a stretch of warps caused when the warps are used up; and multiple circular weaving machines can be operated by one person, therefore the warp waste is reduced, the working efficiency is greatly improved and the labor intensity of workers is improved.

Description

technical field [0001] The invention relates to the field of plastic circular looms, in particular to a self-stopping device at the first time when the circular loom is finished. technical background [0002] At present, the plastic circular looms manufactured, sold and used at home and abroad, whether it is the most commonly used four-shuttle circular loom or small six-shuttle circular loom, 8-shuttle circular loom, and 12-shuttle circular loom, have warp-cutting automatic The stop device is generated by the tension spring of the jumper installed on the main machine. This kind of self-stop device has poor response and sensitivity. During the production and operation, it often happens that the yarn on one bobbin is used up and a large piece of yarn is broken. The operator calls this kind of failure a tap. In order to avoid this kind of failure, the operator often replaces the bobbin yarn when the bobbin yarn is used up, resulting in a large amount of waste warp yarn. The low...

The operator calls this kind of failure a tap. In order to avoid this kind of failure, the operator often replaces the bobbin yarn when the bobbin yarn is used up, resulting in a large amount of waste warp yarn. The low yield also increases the labor intensity of the operator. also seriously affect the normal production
