Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of circular looms, and in particular relates to a warp completion detection device for a circular loom creel. Background Art
[0002] The warp completion detection device of the circular loom creel is a device for detecting whether the weft and warp yarns on the circular loom creel are used up. The warp completion detection device of an ordinary circular loom is installed in front of the warp feed roller of the circular loom. All the warp yarns on one side of the circular loom pass through a warp completion detection device for short-circuit alarm. This causes the alarm range to be too large, and workers cannot immediately determine the position of the warp completion, resulting in a long downtime and reduced production efficiency. Utility Model Content
[0003] The technical problem to be solved by the utility model is: in order to solve the problem in the prior art that all the warp yarns on one side of a circular loom are short-circuited through a warp completion detection device to give an alarm, resulting in an alarm range that is too large, workers cannot immediately determine the position of the warp completion, resulting in a long downtime and reduced production efficiency, a circular loom creel warp completion detection device is now provided.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a circular loom yarn frame warp detection device, comprising a plurality of rows of yarn frames distributed along the longitudinal direction, each row of yarn frames is provided with a yarn package and a detection device for detecting the warp yarn on the yarn package, each row of detection devices comprises a wire hook hung on the warp yarn, a yarn guide plate fixed on the yarn frame and a detection plate located above the yarn guide plate and insulated from the yarn guide plate, the yarn guide plate is provided with a guide hole for the wire hook to pass through, the end of the detection plate away from the yarn frame is bent to form a detection portion for contacting the wire hook, and when the wire hook falls, the wire hook connects the yarn guide plate in this row and the detection plate in the lower row to form a short circuit.
[0005] Furthermore, the wire hook includes a hooking portion and a rod portion located at the bottom of the hooking portion, and the hooking portion is twisted to form a spiral shape for the warp yarn to pass through.
[0006] Furthermore, the detection portion includes a first bending section that bends upward from an end of the detection plate away from the creel and a second bending section that bends from the tail of the first bending section toward the creel.
[0007] Furthermore, the yarn guide plate of each row of detection devices is threadedly connected to the detection plate, and a nylon flat washer and a T-shaped nylon washer are installed between the two.
[0008] Furthermore, the yarn guide plate includes a longitudinal section fixed to the yarn frame and a transverse section fixed to the detection plate, the longitudinal section is provided with a through hole for the warp yarn to pass through, and the guide hole is provided on the transverse section.
[0009] Furthermore, the ends of the longitudinal section and the transverse section are bent to form bent portions.
[0010] Beneficial effects of the utility model:
[0011] 1. The utility model is equipped with a detection device corresponding to each row of creels, so that each row of warp yarns can be detected at the same time. When a certain warp yarn is used up, the creel warp end detection device can locate a certain row of creels, so as to realize more accurate zoned warp end alarm, and the alarm area is smaller. At the same time, the warp end alarm light will light up red, and the warp end position will be displayed on the circular loom control screen. The operator can determine the warp end position more quickly and replace the used warp yarn, which reduces the downtime, improves the working efficiency and reduces the energy consumption.
[0012] 2. The wire hook detects by connecting the upper yarn guide plate with the lower detection plate. The wire hook has a long falling stroke, which can better maintain the tension of the warp yarn after the warp is broken. The wire hook falls naturally and touches the lower detection plate and then slides down. It is efficient and stable and will not cause false alarms. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] When the warp yarn 3 is conveyed normally, the wire hook 4 is hung on the warp yarn 3, and the lower end passes through the guide hole 501 on the yarn guide plate 5. When the warp yarn 3 is used up or disconnected, the wire hook 4 falls along the guide hole 501 under the action of gravity. When the wire hook 4 falls to the point where its upper end contacts the yarn guide plate 5 and its lower end contacts the detection plate 6 in the lower row, the yarn guide plate 5 and the detection plate 6 are connected to form a short circuit, the machine alarm stops, and the indicator light indicates the completed warp area.
