Detailed Description
In order to better understand the technical solution of the present invention, the following embodiments are described in detail with reference to the accompanying drawings.
Referring to the embodiment shown in fig. 1 to 3, a crash-proof chenille automatic stop detection device includes a detection box 1, a base 4 and a mounting frame 6. Detect box 1 and pass through the bolt fastening on base 4, base 4 passes through torsional spring 5 and mounting bracket 6 activity links to each other, and base 4 provides the installation position and protects the bottom that detects box 1 to a certain extent for detecting box 1, receives the striking back when base 4, makes base 4 turn over through the resilience of torsional spring 5 and turns over, and then the protection detects box 1 and is not broken by the collision. The front end of the detection box 1 is provided with a detection notch 2 for monitoring the on-off condition of the chenille yarns in real time, a limit metal sheet 3 is arranged at the detection notch 2, and the limit metal sheet 3 is provided with an oblique U-shaped notch 9 for accommodating the chenille yarns.

The limiting metal sheet 3 provides a contact point for the chenille yarns, and the inclined U-shaped notches 9 formed in the limiting metal sheet limit the displacement of the chenille yarns to a certain extent, so that the chenille yarns are prevented from being directly contacted with the detection box 1 to influence the twist of the chenille yarns. Further, the material of spacing sheetmetal 3 is aluminium oxide, because the chenille yarn is high-speed pull motion under the drive of machine, even if spacing sheetmetal 3 of stainless steel or tungsten steel material, also can pull out the wire casing on spacing sheetmetal 3 for a long time, and aluminium oxide material is hard and plasticity is strong, and low price can effectively avoid yarn wearing and tearing machine and accessory around.
Referring to the embodiment shown in fig. 1, the detection notch monitors the on-off condition of the chenille yarn in real time through an optical device arranged in the detection box 1, and the optical device for detection is a photoelectric emitter 11 and a photoelectric receiver 13 which are used in a matched mode. The detection box 1 is used for detecting the positions required by mounting all electronic components of the chenille yarns, and is sealed in the box, so that the detection effect is prevented from being influenced by any flying and all dust.
