[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Reference Figures 1-5 This utility model provides a device for testing the adhesive coating of polyester yarn, including a housing 1. Two symmetrical first clearance openings 2 are provided on the upper and lower surfaces of the housing 1. A U-shaped plate 3 is bolted into one of the first clearance openings 2 on the upper surface and the other on the lower surface. An ultrasonic thickness detection probe 12 is provided on one side of the U-shaped plate 3. A first display screen 4 and a second display screen 6 are bolted to the upper end of the housing 1. Using the ultrasonic thickness detection probe 12, ultrasonic signals are emitted to the polyester yarn as it passes through the housing 1, thereby detecting the thickness of the adhesive coating on its surface. The detected data is transmitted to the first display screen 4, facilitating observation, simplifying use, saving manpower, and improving detection accuracy.
[0025] In this invention, the first display screen 4 is electrically connected to the ultrasonic thickness detection probe 12 located above the housing 1, and the second display screen 6 is electrically connected to the ultrasonic thickness detection probe 12 located below the housing 1. With the two ultrasonic thickness detection probes 12, simultaneous detection can be performed on the top and bottom of the polyester line as it passes through the housing 1, allowing for multi-point detection and further enhancing the detection effect of the device while significantly reducing detection errors. Two L-shaped strips 13 are mirror-arranged on each of the two U-shaped plates 3. A mounting ring 14 is welded between the two L-shaped strips 13, and the ultrasonic thickness detection probe 12 is fitted inside the mounting ring 14. The L-shaped strips 13 and the mounting ring 14 further secure the ultrasonic thickness detection probe 12, increasing its installation stability and ensuring that the transmitting end of the ultrasonic thickness detection probe 12 is aligned with the polyester line for detection.
[0026] To facilitate the splicing of multiple housings 1, two mirror-shaped L-shaped limiting rods 7 are fixedly connected to one side of housing 1 by bolts, and a T-shaped sliding plate 8 is fixedly connected to the other side of housing 1 by bolts. The shape of the T-shaped sliding plate 8 is the same as the shape formed between the two L-shaped limiting rods 7. By providing L-shaped limiting rods 7 and T-shaped sliding plates 8 on both sides of housing 1, multiple housings 1 can be spliced together to simultaneously detect polyester lines, thereby accelerating the detection efficiency.
[0027] To ensure that the polyester wire passes through the center of the housing 1, a wire guide 10 is bolted between the inner walls of the two sides of the housing 1 near both ends. Two wire guides 21 are bolted between the inner walls of the two sides of the housing 1 near the middle. The wire guides 10 and 21 ensure that the polyester wire passes through the center of the housing 1, which facilitates testing. Two mirror-shaped support frames 9 are bolted to both ends of the lower surface of the housing 1. A second clearance opening 5 is provided in the middle of the upper and lower surfaces of the housing 1. The second clearance opening 5 allows the operator to easily pass the polyester wire through the housing 1.
[0028] To facilitate the splicing and positioning of multiple housings 1, rotating columns 15 are rotatably connected to both ends of each housing 1. Connecting rings 16 are welded to the outer circumference of each rotating column 15. Stops 17 are fixedly connected to the outer circumference of each connecting ring 16 by bolts. The stops 17 can limit the position of both ends when splicing multiple housings 1, thereby preventing the two housings 1 from sliding.
[0029] The use of this utility model involves the following steps:
[0030] S1: Before testing the adhesive layer on the surface of the polyester thread, the polyester thread is first passed through the lead frame 10 at one end of the housing 1, then through two lead frames 11, and finally out through another lead frame 10 at the other end of the housing 1.
[0031] S2: The polyester thread passing through the inside of the housing 1 is subjected to two ultrasonic thickness detection probes 12, which detect the thickness of the polyester thread above and below. The multi-point detection further enhances the detection effect of the device and greatly reduces the detection error.
[0032] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
