[0034] First Embodiment

[0035] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a yarn breakage rapid detection device provided by this utility model; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The diagram shows a first-view, three-dimensional structure of the rapid detection device. Figure 4 for Figure 3 The enlarged schematic diagram of section B is shown below; Figure 5 for Figure 1The diagram shows a second-view perspective three-dimensional structural schematic of the rapid detection device. A rapid yarn breakage detection device includes:

[0036] The detector body 1 has multiple detection heads 2 installed inside it from left to right.

[0037] The protective component 3 is provided in two parts, which are respectively disposed on the left and right sides of the detector body 1. Each protective component 3 includes a protective cover 31 and a plurality of mounting rings 32. The plurality of mounting rings 32 are mounted on the surface of the protective cover 31, and the protective cover 31 is disposed on one side of the detector body 1.

[0038] Fixing component 4, there are two fixing components 4, and the two fixing components 4 are respectively disposed between the two protective covers 31 and the detector body 1;

[0039] Support component 5, there are two support components 5, and the two support components 5 are respectively disposed between the detector body 1 and the two protective covers 31.

[0040] The fixing component 4 includes a U-shaped fixing frame 41, two mounting sleeves 42 and two bolts 43. The U-shaped fixing frame 41 is installed on the surface of the protective cover 31. The two mounting sleeves 42 are symmetrically fitted on the left and right sides of the surface of the U-shaped fixing frame 41. Both mounting sleeves 42 are connected to the side of the detector body 1.

[0041] The two bolts 43 are respectively disposed between the U-shaped fixing bracket 41 and the two mounting sleeves 42.

[0042] The support assembly 5 includes a fixing plate 51, two mounting slots 52 and two mounting blocks 53. The fixing plate 51 is connected to the bottom of the detector body 1. The two mounting slots 52 are symmetrically opened on the left and right sides of the surface of the fixing plate 51. The two mounting blocks 53 are both disposed inside the two mounting slots 52. The two mounting blocks 52 are respectively connected to the bottom of the two protective covers 31.

[0043] The mounting groove 52 and the mounting block 53 are T-shaped and compatible. The use of the mounting groove 52 and the mounting block 52 facilitates the support and positioning of the protective cover 31 when it is installed on the side of the detector body 1. The use of the U-shaped fixing bracket 41 facilitates the use of bolts 43 to fix the U-shaped fixing bracket 41 and the mounting sleeve 42 when the protective cover 31 is installed on the side of the detector body 1.

[0044] Working principle of detector body 1 with multiple detection rings 2:

[0045] I. Photoelectric Detection Principle

[0046] Light emission: Broken yarn detectors usually have a built-in photoelectric emitting device that continuously emits infrared rays of a certain intensity. The infrared rays will form a detection light path in the working area of ​​the detector.

[0047] Yarn obstruction detection: When the yarn passes through the detection optical path normally, the yarn will block part of the light, causing a change in the intensity of the light received by the photoelectric receiver. The circuit inside the detector will analyze and process this change in light intensity to determine whether the yarn is present.

[0048] Broken yarn detection: If the yarn breaks, the light will no longer be blocked, and the intensity of the light received by the photoelectric receiver will return to its initial state (the state when there is no yarn blocking it).

[0049] The detector quickly determines that the yarn has broken by comparing changes in light intensity and issues a corresponding signal (such as an audible and visual alarm).

[0050] II. Capacitance Detection Principle

[0051] Capacitance formation: Some yarn breakage detectors utilize the principle of capacitance. There are electrodes near the detection head, and when the yarn passes through, a capacitance is formed between the yarn and the electrodes.

[0052] As a dielectric, the presence of yarn affects the capacitance.

[0053] Capacitance change detection: Under normal circumstances, the capacitance remains at a certain value when the yarn is present.

[0054] When a yarn breaks, its capacitance value changes significantly. The detector determines whether the yarn has broken by detecting the change in capacitance value.

[0055] III. Mechanical Testing Principles

[0056] Tension sensing: Some yarn breakage detectors work by sensing the tension of the yarn. When the yarn is running normally, it will generate a certain pulling force on the tension sensing component of the detector.

[0057] Yarn breakage response: Once the yarn breaks and the tension disappears, the tension sensing component will trigger the detector to send a yarn breakage signal.

[0058] A connecting frame 6 is installed on the top of the detector body 1.

[0059] The working principle of the yarn breakage rapid detection device provided by this utility model is as follows:

[0060] In use, when blocking dust generated by the yarn passing through the detector body 1 with multiple detection heads 2 and isolating dust generated by external yarn weaving, first install the protective cover 31 with mounting block 53 and U-shaped fixing bracket 41 on the side of the detector body 1. At the same time, the mounting block 53 at the bottom of the protective cover 31 is connected to the mounting groove 52 opened on the surface of the fixing plate 51, and the U-shaped fixing bracket 41 is connected to the mounting sleeve 42 installed on the surface of the detector body 1. After the protective cover 31 is installed, use bolts 43 to pass through the mounting sleeve 42 and thread them to the detector body 1 for use.

[0061] Compared with related technologies, the yarn breakage rapid detection device provided by this utility model has the following advantages:

[0062] This utility model provides a rapid yarn breakage detection device. The device consists of a protective cover 31 with multiple mounting rings 32 on both the left and right sides of a detector body 1 with multiple detection heads 2. It is used in conjunction with two fixing components 4 and a support component 5. This device can control the range of dust generated by the yarn during the yarn processing detection process and also prevent dust generated during the yarn weaving process from adhering to the surface of the detector body 1.

[0065] Specifically, the second embodiment of this application provides a yarn breakage rapid detection device in that the protective cover 31 is provided with a disassembly assembly 7. The disassembly assembly 7 includes a disassembly plate 71, two positioning blocks 72, two positioning grooves 73 and two fixing bolts 74. The two positioning blocks 72 are symmetrically connected to both sides of one side of the disassembly plate 71, and the two positioning grooves 73 are symmetrically opened on the left and right sides of the surface of the protective cover 31.

[0066] A rectangular mounting slot adapted to the disassembly plate 71 is provided on the surface of the protective cover 31. After the disassembly plate 71 is disassembled, the dust at the bottom of the inner wall of the protective cover 31 can be cleaned to prevent the dust inside the protective cover 31 from falling out after disassembly and to temporarily clean the protective cover 31. The positioning block 72 and the positioning slot 73 facilitate the installation between the disassembly plate 71 and the protective cover 31 and the installation of the disassembly plate 71 by means of the fixing bolt 74.

[0067] The two fixing bolts 74 are disposed between the two positioning blocks 72 and the protective cover 31.

[0068] The working principle of the yarn breakage rapid detection device provided by this utility model is as follows:

[0069] When cleaning the dust at the bottom of the inner wall of the protective cover 31, first remove the fixing bolt 74 between the positioning block 72 and the protective cover 31. After the fixing bolt 74 is removed, pull the disassembly plate 71 to separate it from the protective cover 31. At the same time, the disassembly plate 71 will cause the positioning block 72 to separate from the positioning groove 73, so that the dust at the bottom of the inner wall of the protective cover 31 can be cleaned.
