Technical Field

[0001] The utility model relates to the technical field of thread break warning for textile machinery, in particular to a high-precision thread break warning device for textile machinery. Background Art

[0002] Textile machinery refers to the various mechanical equipment required to process natural or chemical fibers into textiles. Although the machinery for producing chemical fibers includes a variety of chemical machinery, it is now considered an extension of textile machinery and belongs to the broad category of textile machinery. The processes required to process different fibers such as cotton, linen, silk, and wool into textiles are not the same, and some are completely different, so the machines required are also of various types. Textile machinery is usually classified according to the production process, including: spinning equipment, weaving equipment, printing and dyeing equipment, finishing equipment, chemical fiber spinning equipment, reeling equipment, and non-woven fabric equipment.

[0003] When existing textile machinery is performing textile operations, if the thread is broken when the thread reel is being pulled, due to the large number of thread reels, when the thread of some reels is broken, due to the lack of warning devices, it is not easy for operators to find it, resulting in the collapse of the produced products, and even damage to the machinery and equipment, causing great losses, and even causing major accidents. Utility Model Content

[0004] Based on this, it is necessary to provide a high-precision textile machinery breakage warning device to address the above technical problems.

[0010] Preferably, a second spring is installed in the through slot, the second spring corresponds to the limiting plate one-to-one, and one end of the second spring is connected to the limiting plate.

[0011] Compared with the prior art, this technical solution has at least one of the following beneficial effects:

[0012] Through the coordinated setting of sensor 1 and sensor 2, when the yarn breaks, the extrusion block squeezes the slider to cause pressure on sensor 1, thereby giving a prompt, and when the extrusion block moves upward, the lower extrusion wheel and the brake plate rub against each other to brake, thereby sending a signal from sensor 2. The two detection methods are carried out simultaneously, avoiding inaccurate detection by a single detection method;

[0013] Through the setting of the limit plate, when the extrusion block moves up, the limit plate is also driven to move up, so that the limit plate cooperates with the upper extrusion wheel or the lower extrusion wheel to clamp the yarn inlet end, so that the broken end of the yarn can be easily found, thereby reducing the burden on the staff.

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0019] See also Figures 1 to 3The embodiment of the present application provides a high-precision textile machinery broken wire warning device, including a frame 1 and a yarn 101. A front guide wheel 2 and a rear guide wheel 3 are installed on the frame 1. A through slot 4 is provided on the frame 1. A squeezing block 5 is slidably connected in the through slot 4. A lower squeezing wheel 6 is rotatably connected to the squeezing block 5. A spring 7 is installed in the through slot 4. One end of the spring 7 is connected to the squeezing block 5. A slide slot 8 is provided on the frame 1. A slider 9 is slidably connected in the slide slot 8. An upper squeezing wheel 10 is rotatably connected to the slider 9. A sensor 11 is installed in the slide slot 8. The sensor 11 can be a pressure sensor. A sensor 2 12 is installed on the squeezing block 5. The sensor 2 12 can be a rotation detection sensor. The sensor 2 12 is connected to the lower squeezing wheel 6. Brake plates 13 are installed on both sides of the frame 1. The brake plates 13 are arranged in cooperation with the lower squeezing wheel 6. When working, the yarn 101 is located between the lower squeezing wheel 6 and the upper squeezing wheel 10 and abuts against both of them.

[0020] In this embodiment, the yarn 101 passes through the bottom of the front guide wheel 2, between the lower extrusion wheel 6 and the upper extrusion wheel 10, and the bottom of the rear guide wheel 3 in sequence, so that the yarn 101 exerts a certain pressure on the lower extrusion wheel 6 due to the stretching effect of the front guide wheel 2 and the rear guide wheel 3. When the yarn 101 is disconnected, the pressure of the yarn 101 on the lower extrusion wheel 6 disappears, so that the compressed spring 7 can drive the lower extrusion wheel 6 to move upward through the extrusion block 5, and the lower extrusion wheel 6 moves upward and squeezes the upper extrusion wheel 10, and the upper extrusion wheel 10 drives the slider 9 to move upward, thereby The sensor 19 generates pressure, so that the sensor 19 can generate a signal, and when the lower extrusion wheel 6 moves up, it will rub against the brake plate 13, so that the lower extrusion wheel 6 stops rotating, so that the sensor 12 can send a signal to indicate that the yarn 101 is broken. The two detection methods are carried out in parallel, so when a single detection method is damaged and cannot be detected, the other detection method can also detect the breakage of the yarn 101; because of the gravity of the slider 9 and the upper extrusion wheel 10, the upper extrusion wheel 10, the yarn 101, and the lower extrusion wheel 6 are in contact with each other in sequence.

[0021] In some embodiments, in order to further improve the practicality of the device, two limit plates 16 are slidably connected in the through groove 4. The through groove 4 is a mountain-shaped through groove. The two limit plates 16 are connected to the extrusion block 5. The two limit plates 16 are respectively arranged in cooperation with the front guide wheel 2 and the rear guide wheel 3. After the wire is broken, the extrusion block 5 moves up while the two limit plates 16 move up with the extrusion block 5, so that at the inlet end of the yarn 101, the limit plate 16 cooperates with the front guide wheel 2 or the rear guide wheel 3 to fix the broken yarn 101, which is convenient for subsequent staff to reconnect it; when the yarn 101 is pulled, it is pulled by its outlet end, so when the inlet end is fixed, the yarn 101 can be fixed; the setting of the two limit plates 16 makes it unnecessary to determine the order of installing the inlet and outlet when installing the device, which improves practicality.

[0022] In some embodiments, in order to facilitate friction braking of the lower extrusion wheel 6, chamfers are provided on the brake plate 13 and the lower extrusion wheel 6. The chamfers increase the friction area and the friction force.

[0023] In some embodiments, in order to protect the friction part of the brake plate 13 , a rough wear-resistant layer 14 is provided on the brake plate 13 .

[0024] In some embodiments, in order to facilitate the transmission of the yarn 101 breakage signal, a warning light 15 is installed on the frame 1.

[0025] In some embodiments, in order to prevent the elastic force of spring 17 from being insufficient to move the added limit plate 16 to the specified position, a spring 2 17 is installed in the through slot 4, and the spring 2 17 corresponds to the limit plate 16 one by one, and one end of the spring 2 17 is connected to the limit plate 16.
