Description

Technical Field

[0001] The utility model belongs to the technical field of yarn devices, and in particular relates to a device for quickly identifying the number of yarns and whether the yarn is broken or lacking during a movement process. Background Art

[0002] In the production process of textile, pultrusion and other fields, due to the large number of yarns, when problems occur, if they are confirmed manually, there are the following problems:

[0003] First, it is time-consuming and labor-intensive (it is impossible to quickly identify which yarn has a problem and needs to be searched for constantly);

[0004] Second, after the problem is discovered, the product has already had problems (yarn shortage, yarn breakage);

[0005] Third, it is easy to confirm errors when there are too many yarns;

[0006] Fourth, it is impossible to grasp the changes in yarn tension during movement.

[0007] Therefore, a device is provided for quickly identifying the number of yarns and whether the yarn is broken or lacking during the movement process. Utility Model Content

[0008] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a device for quickly identifying the number of yarns and whether the yarn is broken or missing during the movement process.

[0009] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0010] A device for quickly identifying the number of yarns and whether the yarn is broken or missing during the movement process, comprising a yarn threading identification control board, the yarn threading identification control board is provided with a plurality of yarn threading holes, and the left and right sides of the yarn threading identification control board are both provided with connecting shafts;

[0011] The connecting shaft on the left side of the yarn threading identification control board is connected to the motor, and the connecting shaft on the right side of the yarn threading identification control board is connected to the angle sensor;

[0012] The rear side of the yarn threading identification control panel is connected with a plurality of tension sensors, the tension sensors correspond to the yarns in the yarn threading holes, and the yarns pass through the guide wheels of the tension sensors.

[0013] It is further defined that a cross-flow fan is arranged on the upper edge of the yarn threading identification control panel. With such a structural design, the cross-flow fan has a large air supply range and can cover the distribution range of the yarn threading holes. The air supply of the cross-flow fan can avoid the accumulation of wool yarn caused by yarn threading. The gas exhausted by the cross-flow fan is evenly distributed along the width direction of the cross-flow fan and can be blown evenly. In addition, the cross-flow fan has radial air inlet and radial air exhaust, and its air inlet and exhaust directions are suitable for the yarn threading identification control panel. The air inlet direction is perpendicular to the direction of the yarn threading identification control panel, and the exhaust direction is parallel to the direction of the yarn threading identification control panel.

[0014] It is further defined that the yarn threading identification control board is connected to a grounding wire. With such a structural design, the grounding wire can conduct static electricity generated by yarn threading friction.

[0015] It is further defined that it also includes a controller for receiving tension sensor signals, and the controller is connected to a display screen. With such a structural design, the controller is used to receive tension sensor signals, and the display screen displays the signals of the tension sensor in a visual manner and provides a platform for control input by the staff.

[0016] It is further defined that the controller is connected to an alarm. With such a structural design, the alarm can sound an alarm when the tension sensor detects yarn breakage or insufficient tension. After receiving the signal actively sent by the alarm, the staff can deal with the production abnormality in time to avoid production losses.

[0017] Beneficial effects of the utility model:

[0018] 1. It can judge the yarn tension and whether there is yarn breakage or yarn shortage. The yarn passes through the guide wheel of the tension sensor through the yarn threading hole. The tension sensor detects the tension on the yarn. If the yarn is broken or missing, the tension detected by the tension sensor is zero. Therefore, it can be judged whether there is a problem with the yarn at this position. If the tension sensor is triggered, it means that there is yarn here. By counting the return signal of the tension sensor, the total number of yarns can be calculated;

[0019] 2. The rotation of the yarn threading identification control panel can adjust the tension of multiple yarns to be consistent, ensuring uniform tension of each layer of yarn;

[0020] 3. It can effectively avoid the problem of wool yarn accumulation during yarn threading. BRIEF DESCRIPTION OF THE DRAWINGS
