Description

Technical Field

[0001] The utility model relates to the field of yarn warping machines, and specifically to a broken yarn monitoring device for a warping machine. Background Technique

[0002] In a Chinese patent with the publication number CN213896132U, a broken yarn monitoring device for a warping machine used in the weaving of anti-deformation polyester cloth is disclosed, including a support table. A number of support columns are connected to the bottom end surface of the support table. A workbench is arranged above the support table. A yarn rack and a warping mechanism are respectively arranged on the left and right sides of the support table. When in use, during normal operation, the first spring is in a stretched state. Under the action of the baffle, the infrared receiver cannot receive infrared rays, and the alarm lamp does not light up. At the same time, the second spring is in a compressed state, and the first contact switch is not connected to the second contact switch, and the warning lamp does not light up. When the yarn breaks, the first spring and the second spring reset. The infrared receiver receives the infrared rays emitted by the infrared emitter. The infrared contactor transmits the received signal to the controller, and the controller controls the alarm lamp to light up. At the same time, the first contact switch contacts the second contact switch, causing the warning lamp to light up. When the alarm lamp and the warning lamp light up simultaneously, it can be judged that the yarn is broken, and the monitoring is more accurate. In this patent, the hook and the wire wheel respectively abut against the yarn under the action of two groups of elastic members. When the yarn breaks, the states of the two groups of elastic members change, thereby controlling the start of the alarm, etc. However, in this patent, the elastic restoring forces of the two groups of elastic members directly act on the yarn, causing the yarn to bear the acting forces of the elastic members and the detection device, increasing the internal tension and making the structure of the yarn itself unstable.

[0003] Based on this, the utility model designs a broken yarn monitoring device for a warping machine to solve the above problems. Content of the Utility Model

[0021] Preferably, an adjustment seat 31 is arranged on the detection table 3. A first telescopic component 32 is arranged between the detection table 3 and the adjustment seat 31. The installation rack 4 is arranged on the adjustment seat 31.

[0025] Preferably, an anti-slip layer 8 is arranged on the first roller 5 and the second roller 6.

[0026] Specific application embodiments of the present utility model:

[0027] The detection table 3 is arranged on one side of the yarn rack 1 close to the yarn rack 1 between the yarn rack 1 and the warping mechanism 2. When the yarn breaks, the yarn on the side close to the yarn rack 1 loses the drive of the warping mechanism 2 and thus stops moving. The first roller 5 arranged in the detection table 3 abuts and matches the yarn. When the yarn moves driven by the warping mechanism 2, the movement of the yarn drives the first roller 5 to rotate. The first detection component 51 arranged in the detection table 3 can be a photoelectric sensor. The first detection component 51 detects the rotation speed of the first roller 5. By detecting whether the first roller 5 rotates through the first detection component 51, the detection of whether the warping machine breaks yarn is achieved.

[0028] The first telescopic component 32 can be made of an electric telescopic rod. By driving the adjusting seat 31 to move longitudinally through the first telescopic component 32, the longitudinal height of the mounting bracket 4 and the first roller 5 provided on the adjusting seat 31 is adjusted, which is beneficial for the first roller 5 to be in mutual contact with the yarn, ensuring that the movement of the yarn can drive the first roller 5 to rotate.

[0029] The second roller 6 and the first roller 5 are respectively arranged on opposite sides of the yarn, avoiding misjudgment of whether the yarn is broken due to factors such as roller slippage, where the yarn is not broken but the roller does not rotate.

[0030] The first elastic member 71 can be made of a spring. Driven by the elastic restoring force of the spring, the moving plate 7 moves towards the first roller 5. The second roller 6 is arranged on the moving plate 7 and also moves towards the first roller 5, which is beneficial for ensuring that the first roller 5 and the second roller 6 are in mutual contact with the yarn. The second detection component 61 and the first detection component 51 are the same photoelectric sensors, and the second roller 6 is detected. The structures of the second roller 6, the second detection component 61 and the first roller 5, the first detection component 51 are the same.

[0031] The anti-slip layer 8 is arranged on the side surface where the roller is in mutual contact with the yarn, which is beneficial for ensuring that the movement of the yarn drives the roller to rotate.
