In a broad sense, textile machinery also includes chemical machinery for producing chemical fibers. Textile machinery is the means of production and material basis of the textile industry.

[0003] The current textile equipment is generally a mechanical equipment for processing yarn or processing yarn into fabric. Therefore, the operation of the textile equipment is inseparable from the yarn, and the running yarn generally has tension. When the external force is greater than the limit tension of the yarn, it will cause the yarn to break. After the yarn breaks, the textile equipment needs to be stopped in time to avoid greater losses. Therefore, general textile equipment needs to be equipped with a yarn break detection device to control the stop of the textile equipment;

[0004] However, the detection accuracy of traditional broken thread detection devices is average, and broken threads are often not discovered. Although traditional broken thread detection devices can monitor the broken thread of yarn, the yarn will fall off after it breaks, causing the staff to need to find the thread ends and connect the broken threads. However, the broken yarn is too thin, which is not convenient for the staff to find. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0030] Please refer to Figures 1 to 4As shown, a yarn breakage detection device of the utility model comprises a mounting platform 1, a guide assembly, a clamping assembly, an air pressure piece 13 and a detection mechanism, a plurality of the guide assemblies are arranged on both sides of the mounting platform 1, a plurality of the detection mechanisms are installed in the middle of the mounting platform 1, a detection mechanism is arranged between two guide assemblies arranged opposite to each other, a clamping assembly is arranged on one side of the guide assembly away from the detection mechanism, and the clamping assembly is connected to the air pressure piece 13;

[0031] The detection mechanism includes an adjustment component and a detection component, the bottom of the adjustment component is fixedly connected to the mounting platform 1, and the top of the adjustment component is installed with the detection component;

[0032] The clamping assembly comprises two clamping parts, a connecting pipe 18, a connecting pipe 15 and a valve body 14. The two clamping parts are arranged relative to each other and are installed on the mounting platform 1. The clamping parts are respectively connected to the top of the connecting pipe 18, and the bottom of the connecting pipe 18 is connected to the upper part of the connecting pipe 15. The valve body 14 is arranged at the lower part of the connecting pipe 15, and the valve body 14 is connected to the air compressor 13 through an air guide pipe.

[0033] The working principle of the utility model is as follows: during the actual yarn processing process, when it is necessary to detect the yarn breakage, the yarn can be guided into the guide component on one side of the mounting platform 1, and the yarn can be passed through the detection component, and then the yarn can be guided out of the guide component on the other side of the mounting platform 1, and then the yarn can be tensioned by adjusting the component, and the yarn breakage can be detected by the detection component. When the yarn breaks, the detection component detects the breakage and transmits a signal, and then the valve body 14 is operated to make the air compressor 13 introduce the compressed air into the connecting pipe 15 through the air guide pipe, and introduce the compressed air into the clamping components through the connecting pipe 15, and the broken wire is clamped by the clamping components.

[0034] Furthermore, the clamping member includes a mounting plate 4 and an airbag 5, the bottom of the mounting plate 4 is fixedly connected to the mounting platform 1, the airbag 5 is arranged on the mounting plate 4, an airway is arranged inside the mounting plate 4, the airbag 5 is connected to the airway, and the top of the connecting tube 18 is connected to the airway.

[0035] From the above description, it can be seen that when the broken wire needs to be clamped, the valve body 14 is opened, and the compressed air enters the airway through the connecting pipe 15 and the connecting pipe 18, and inflates the airbag 5 through the airway, causing the airbag 5 to swell quickly, and the broken wire is clamped by two opposite airbags 5.

[0037] It can be seen from the above description that when the yarn needs to be guided, the yarn can pass through the gap between the two guide wheels 3, and the friction force generated on the yarn can be reduced by the guide wheels 3.

[0038] Furthermore, the adjustment component includes a mounting tube 12, a telescopic member 11 and a linear drive member 19.

When the yarn breaks, the pressure value on the pressure sensor 16 changes and a signal is transmitted.

[0042] Furthermore, the outer surface of the pressing wheel 8 is inwardly recessed to form a limiting groove 17, and the limiting groove 17 is used to limit the random movement of the yarn.

[0043] As can be seen from the above description, it is beneficial to limit the random movement of the yarn through the limiting groove 17 to avoid changes in the pressure value.

[0044] Furthermore, it also includes an infrared sensor 7 . An infrared sensor 7 is respectively disposed on both sides of the pressing wheel 8 , and the infrared sensors 7 are connected to the second mounting frame 9 .

[0045] As can be seen from the above description, it is beneficial to sense the yarn through the infrared sensor 7 and transmit a signal when the yarn breaks.
