[0020] A preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.

[0021] See also Figures 1 to 3 The utility model provides an embodiment of an adjustable detection device for protrusions on the surface of textile fabrics, which includes a receiving rack 1 and a group of optical fibers 2. The receiving rack 1 includes a base 11 and two side panels 12 arranged on the base 11 in parallel and at intervals. A plurality of rollers 4 for transmitting textile fabrics 3 are rotatably connected between the two side panels 12. The two ends of each roller 4 are rotatably connected to the two side panels 12, and the rollers 4 are staggered according to certain requirements to ensure that the textile fabrics remain flat during the transmission process. Among them, a plurality of detection blocks (not shown in the figure) arranged in sequence along the X direction are arranged at a roller near the optical fiber 2. When the textile fabric passes through the roller, a protrusion of a certain size on it collides with the detection block at the corresponding position, so that the detection block tilts up to block the signal of the optical fiber 2. After receiving the signal, the textile machine controller makes a corresponding response action. The detection structure and process of the protrusions on the surface of the textile fabrics are the same as those in the prior art, and this application will not repeat them.

[0022] Specifically, in the present embodiment, a group of opposing optical fibers 2 are respectively arranged on two side panels 12 through adjustable components 5, so that the opposing optical fibers 2 can not only move in the X, Y, and Z directions, but also can be quickly disassembled and replaced; each adjustable component 5 includes an X-direction adjustment unit 51, a Y-direction adjustment unit 52, and a Z-direction adjustment unit 53, the X-direction adjustment unit 51 is movably arranged on the corresponding side panel 12, the Y-direction adjustment unit 52 is movably arranged on the X-direction adjustment unit 51, the Z-direction adjustment unit 53 is movably arranged on the Y-direction adjustment unit 52, and the opposing optical fiber 2 is arranged on the Z-direction adjustment unit 53.

[0023] Further, the X-axis adjustment unit 51 includes a movable plate 511 arranged along the X-axis, and a first waist-shaped slot 5111 is provided on the movable plate 511 along the X-axis. The movable plate 511 is movably connected to the upper end surface of the corresponding side plate 12 through the first positioning bolt 512 passing through the first waist-shaped slot 5111. It can be understood that the upper end surface of the side plate 12 is provided with a threaded hole matching the first positioning bolt 512. When it is necessary to move the optical fiber along the X-axis, the first positioning bolt 512 is loosened, and the movable plate 511 is pushed. The first waist-shaped slot 5111 of the movable plate 511 moves under the guidance of the first positioning bolt 512, driving the optical fiber 2 on it to move toward the negative side of the X-axis to approach the side plate 12 for the insertion of the textile before the operation; or to move toward the positive side of the X-axis away from the side plate 12 for the detection of the protrusions on the surface of the textile.

[0024] Furthermore, the Y-axis adjustment unit 52 includes a horizontal portion 521 and a vertical portion 522 connected to the horizontal portion 521 and extending vertically downward. The horizontal portion 521 is arranged on the upper portion of the X-positive end of the movable plate 511, and the side surface of the X-negative side of the vertical portion 522 abuts against the end surface of the X-positive end of the movable plate 511, that is, the Y-axis adjustment unit 52 has a "7" shape structure, and its bending part is adapted to the bending part of the X-positive end of the movable plate 511 to ensure the stable positioning of the Y-axis adjustment unit 52.

[0025] Among them, a second waist-shaped slot hole 5211 is opened on the horizontal part 521 along the Y direction, and the Y-direction adjustment unit 52 is movably connected to the movable plate 511 through the second positioning bolt 523 passing through the second waist-shaped slot hole 5211. That is, a threaded hole matching the second positioning bolt 523 is provided on the movable plate 511 near the positive end of the X direction. When it is necessary to move the opposite optical fiber 2 on the Y axis, the second positioning bolt 523 is loosened, and the Y-direction adjustment unit 52 is pushed. The second waist-shaped slot hole 5211 of the horizontal part 521 moves on the Y axis under the guidance of the second positioning bolt 523 and the X-direction end of the movable plate 511, thereby driving the opposite optical fiber 2 to move on the Y axis.

[0026] Furthermore, the Z-direction adjustment unit 53 includes a positioning slider 531, and a third waist-shaped slot 5311 is provided on the positioning slider 531 along the Z direction. The positioning slider 531 is slidably connected to the X-positive side of the vertical portion 522 through the third waist-shaped slot 5311 via a third positioning bolt 532, and the opposite-direction optical fiber 2 is arranged on the positioning slider 531. That is, a threaded hole matching the third positioning bolt 532 is provided on the vertical portion 522 of the Y-direction adjustment unit 52. When it is necessary to move the opposite-direction optical fiber 2 on the Z axis, the third positioning bolt 532 can be loosened to adapt to textile fabrics of different thicknesses or to meet the needs of adjusting and detecting different protrusion heights at any time. At the same time, by unscrewing the third positioning bolt 532, the opposite-direction optical fiber 2 can be quickly removed from the adjustable component 5, which is convenient for quick disassembly and assembly of the opposite-direction optical fiber 2 and has strong applicability.

[0027] Furthermore, a slide groove 5221 adapted to the positioning slider 531 is provided on the X-positive side of the vertical portion 522 along the Z direction. The setting of the slide groove 5221 enables the positioning slider 531 to keep the Z-axis movement to ensure the vertical movement of the irradiated optical fiber 2.

[0028] Furthermore, to ensure the stability of the reflected optical fiber 2 in the Z direction, the Z direction adjustment unit 53 also includes a fixed block 533, an adjustment screw 534 and a hand wheel 535. The fixed block 533 is arranged in the positioning groove 5212. The adjustment screw 534 is arranged along the Z direction, and its lower end is connected to the positioning slider 531. The upper end passes through the fixed block 533 and is connected to the hand wheel 535. The adjustment screw 534 is threadedly connected to the fixed block 533. By turning the hand wheel 535, the adjustment screw 534 rotates relative to the fixed block 533, thereby driving the positioning slider 531 to move up and down along the Z direction.

[0029] In addition, a T-slot 5312 is provided at the upper end of the positioning slider 531, and a connecting block 5341 adapted to the T-slot 5312 is provided at the lower end of the adjusting screw 534. That is, the T-slot 5312 and the connecting block 5341 are in a quick-disassembly matching mode, and by unscrewing the third positioning bolt 532 and moving the positioning slider 531 along the positive X-direction side, the T-slot 5312 of the positioning slider 531 and the connecting block 5341 at the lower end of the adjusting screw 534 can be quickly separated, thereby realizing quick disassembly of the positioning slider 531; conversely, realizing quick assembly of the positioning slider 531.

[0030] In summary, the adjustable detection device for protrusions on the surface of textile cloth provided by the utility model arranges a group of opposing optical fibers on two side panels through adjustable components, so that the opposing optical fibers can not only move upward in X, Y, and Z directions, but also can be quickly disassembled and replaced, which is convenient for the insertion of textile cloth, and can adjust the position according to the height of the protrusion to be detected. It has a simple structure, is easy to operate, and has strong applicability.
