BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 The present invention is a schematic diagram of a yarn break detection device for a roving frame.

[0014] Figure 2 Schematic diagram of the drafting system. DETAILED DESCRIPTION

[0015] like Figure 1 and Figure 2 As shown, a yarn break detection device for a roving machine includes a drafting system 1, a spinning system 2 and a power system. The drafting system 1 drafts the yarn into the spinning system 2, and the power system provides power for the drafting system 1 and the spinning system 2. The power system enables the drafting system 1 to draft the yarn into the spinning system 2 for spinning; it includes an alarm system 3, a monitoring system 4 and a control system 5. The monitoring system 4 is located on one side of the drafting system 1 and is used to detect the real-time state of the yarn; the alarm system 3 is electrically connected to the control system 5, and the monitoring system 4 is electrically connected to the control system 5. When the yarn is bubbling, missing or disconnected, the monitoring system 4 will upload the situation of the yarn bubbling, missing or disconnected to the control system 5, and the control system 5 will stop the power system from providing power to the drafting system 1, and the alarm system 3 will also receive the signal of the yarn bubbling, missing or disconnected transmitted by the control system 5, and the alarm system 3 will emit an alarm sound to remind the staff that the yarn is in an abnormal state, and check and correct it in time.

[0016] The monitoring system 4 includes a plurality of visual detection cameras 6, each of which is electrically connected to the control system 5, and each of which monitors the yarn conditions in real time and uploads them to the control system 5; each of which is fixed on the ground through a fine-tuning component. The textile system 2 is provided with a plurality of wooden tube wheels 7 for spinning, and the drafting system 1 winds the yarn onto the wooden tube wheel 7, and the visual detection camera 6 can detect the working status of multiple yarns at the same time. Each visual detection camera 6 can detect the status of 24 yarns at the same time, and the visual detection camera 6 transmits the image to the control system 5, which simplifies the monitoring system structure 4, improves the spinning quality and efficiency, reduces the labor intensity, and is suitable for diversified spinning process requirements. The control system 5 will perform feature comparison on the imaged picture and generate a comparison result, and then convert the comparison result into a binary form, and process the binary comparison result through the PLC processing unit in the control system 5, and obtain the final detection result, so as to quickly determine the position of the yarn abnormality.

[0017] The alarm system 3 includes an alarm, which is fixedly connected to the drafting system 1. When the yarn is broken, the alarm will receive a signal transmitted by the control system 5, and the alarm will remind the staff that the yarn is broken. After the control system 5 receives the signal of yarn abnormality, the control system 5 will immediately transmit the signal to the alarm, and the alarm will warn the staff that the yarn is abnormal, and check and correct it in time.

[0018] The control system 5 includes a display 8 and a button 9. The display 8 can display the yarn image transmitted in real time by the monitoring system 4, and the staff can control the start and stop of the power system through the button 9. The display 8 enables the staff to observe the state of each yarn more intuitively, and the button 9 enables the staff to control the power system and the alarm system 3, and can stop or start the power system, and can also stop the alarm system 3.

[0019] The fine-tuning assembly includes a horizontal adjustment member 11 and a telescopic rod 12. The visual inspection camera 6 is connected to the telescopic rod 12 through the horizontal adjustment member 11. The visual inspection camera 6 can be rotated in the horizontal direction on the horizontal adjustment member 11, and the telescopic rod 12 can move the visual inspection camera 6 in the vertical direction. When the drafting system 1 and the spinning system of different specifications are replaced, the visual inspection camera 6 can be adjusted to a suitable angle in the horizontal direction through the horizontal adjustment member 11, and the telescopic rod 12 modulates the visual inspection camera 6 to a suitable height to adapt to the drafting system 1 and the spinning system of different specifications, thereby increasing the universality of the monitoring system 4.
