[0034] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] This utility model embodiment provides a fabric inspection machine, such as Figure 1 As shown, the machine includes a frame 1, with a feeding roller group 2 at one end and a discharging roller group 3 at the other end. Undetected rolls 16 are located at the feeding roller group 2, while detected rolls 17 are located at the discharging roller group 3. Correspondingly, a guide roller group is provided on the frame 1. The guide roller group is used to guide the fabric 18, so that the fabric 18 moves in a certain direction. Thus, the fabric 18 that is not detected at the feeding roller group 2 can be guided by the guide roller group to the detected rolls 17 at the discharging roller group 3 for collection.

[0038] Specifically, to achieve automated inspection, a visual inspection device 5 is also provided. This device performs image detection on the fabric 18 and feeds the results back to the operating end of the fabric inspection machine, thus achieving automated inspection. However, this is existing technology. In existing technology, the visual inspection device 5 is mounted on the frame 1, and the motors for the feeding roller group 2 and the discharging roller group 3 are also correspondingly mounted on the frame 1. When the fabric inspection machine starts, the motor vibration is transmitted to the frame 1, and thus to the visual inspection device 5, causing it to vibrate as well. This vibration can affect the imaging effect of the visual inspection device 5. Therefore, to prevent this from happening, in this embodiment, as... Figures 1-2 As shown, a separate mounting rack 4 is provided for placing the visual inspection device 5. The detection end of the visual inspection device 5 faces the front of the fabric 18 to photograph it. This independent mounting rack 4 ensures that the visual inspection device 5 has no physical contact with the fabric inspection machine body, achieving vibration isolation and effectively preventing the impact of motor vibration on the photographing effect of the visual inspection device 5. Furthermore, the mounting rack 4 is located inside the frame 1, specifically in the space below the frame 1, and is placed on the ground like the frame 1. This significantly saves space, making the entire fabric inspection machine more compact and efficient.

[0039] Specifically, the guide roller group includes a first roller group 6, a first reversing roller 7, a second roller group 8, and a third roller group 9. The fabric 18 not yet detected at the feeding roller group 2 is sequentially wound around the outside of the first roller group 6, the first reversing roller 7, the second roller group 8, and the third roller group 9, ultimately guiding it to the detected fabric roll 17. In other words, the movement direction of the fabric 18 is defined by the first roller group 6, the first reversing roller 7, the second roller group 8, and the third roller group 9. Specifically, the first roller group 6 and the second roller group 8 are positioned close to the feeding roller group 2, with the first roller group 6 located below the second roller group 8. The third roller group 9 is located at the discharge roller group 3. The fabric 18 is wound around the outside of the first roller group 6 with its front side facing upwards. Then, the fabric 18 passes through the first reversing roller 7 and is wound around the outside of the second roller group 8, with the front side of the fabric 18 wound from the lower part of the second roller group 8 facing downwards. Correspondingly, the placement frame 4 includes a support plate 41 and a placement plate. 42, wherein two support plates 41 are provided to form a goal frame structure. Correspondingly, the fabric between the feeding roller group 2, the first roller group 6 and the first reversing roller 7 will be arranged to form a placement space. The two support plates 41 are respectively located on the front and rear sides of the fabric at the first roller group 6, and are respectively connected to the two ends of the placement plate 42. They are used to place the placement plate 42 on the external ground to support the placement plate 42. Except for the ends, the support plates 41 are all located in the placement space. The vision inspection device 5 is installed in the middle of the placement plate 42 and is positioned facing the fabric 18 wrapped around the lower part of the second roller group 8 to take pictures of the front of the fabric 18. The vision inspection device 5 is not higher than the feeding roller group 2, that is, the vision inspection device 5 is also located in the placement space and is wrapped in the space formed by the movement of the fabric 18. This avoids the problem of workers accidentally touching the vision inspection device 5 and affecting the shooting effect, and further improves the reliability and stability of the equipment.

[0040] Specifically, the second roller group 8 is located at the upper end of the frame 1, the first roller group 6 is located at the lower end of the frame 1, and the vision inspection device 5 is located at the first roller group 6. This increases the detection distance of the vision inspection device 5 to the fabric 18 to a certain extent, allowing the vision inspection device 5 to capture a larger area. Preferably, the vision inspection device 5 is a line scan camera, and in actual use, the shooting distance between the line scan camera and the fabric 18 wrapped around the lower part of the second roller group 8 is set to at least 1.2 meters.

[0041] Furthermore, the second roller group 8 includes a third roller 81, a fourth roller 82, and a fifth roller 83. The third roller 81 is located to the lower left of the first reversing roller 7, the fourth roller 82 is located to the upper left of the third roller 81, and the fifth roller 83 is located to the upper right of the fourth roller 82. Thus, the fabric 18 is redirected by the first reversing roller 7 to a position below the third roller 81, with the front of the fabric 18 facing down. The fabric 18 is then sequentially wound around the outside of the third roller 81, the fourth roller 82, and the fifth roller 83, so that the front of the fabric 18 is outside the space enclosed by the third roller 81, the fourth roller 82, the fifth roller 83, and the first reversing roller 7. This ensures that the front of the fabric 18 wound around the outside of the third roller 81 faces the visual inspection device 5. The device 5 can directly capture an image of the front of the fabric 18 outside the third roller 81. Due to the position of the third roller 81, it protrudes downward relative to the first reversing roller 7 and the fourth roller 82. This design allows the fabric at this position to form a smoother and more uniform transition when pressed by the rollers, thereby effectively reducing the generation of creases. As a result, the fabric 18 in the image captured by the visual inspection device 5 is basically free of creases, which can more effectively detect whether there are defects on the front of the fabric 18 and avoid the situation where the defects are covered by creases and are not detected. In actual use, it can filter out more than 85% of ordinary fabric creases, greatly reducing the interference of creases on the visual inspection results.

[0042] Specifically, in order to improve the imaging effect of the visual inspection device 5, a positive light source 12 and a bottom light source 13 are provided at the second roller group 8. Both the positive light source 12 and the bottom light source 13 are mounted on the frame 1. The positive light source 12 is located below the second roller group 8 and is used to illuminate the front side of the fabric 18 wound around the bottom of the second roller group 8. The bottom light source 13 is located in the space enclosed by the second roller group 8 and the first reversing roller and is used to illuminate the back side of the fabric 18 wound around the bottom of the second roller group 8. This can enhance the brightness of the fabric 18 wound around the bottom of the second roller group 8, making the features in the image captured by the visual inspection device 5 more obvious and easier to identify.

[0043] Preferably, the guide roller group further includes a second reversing roller 10 and a third reversing roller 11 arranged along the movement direction of the fabric 18. The second reversing roller 10 is arranged close to the second roller group 8, and the third reversing roller 11 is arranged close to the third roller group 9. The third reversing roller 11 is located below the second reversing roller 10, so that the fabric 18 will sequentially pass around the first roller group 6, the first reversing roller 7, the second roller group 8, the second reversing roller 10, the third reversing roller 11, and the third roller group 9 to the discharge roller group 3. Specifically, a lower polishing plate 14 is provided between the second reversing roller 10 and the third reversing roller 11. The lower polishing plate 14 is inclined and parallel to the fabric 18 between the second reversing roller 10 and the third reversing roller 11, and is located inside the fabric 18. So that during the operation of the fabric inspection machine, the lower polishing plate 14 emits light, illuminating the fabric 18 between the second reversing roller 10 and the third reversing roller 11, and the operator can visually observe defects here and then mark them. Specifically, during the operation of the fabric inspection machine, the visual inspection device 5 captures an image of the fabric 18 at the second roller group 8. If a defect is detected in the image, the motor on the fabric inspection machine will stop. Due to inertia, the defective fabric 18 will move to the front of the lower polishing plate 14. The operator at the front of the lower polishing plate 14 will then observe the defect on the fabric 18 and mark it with a label. Correspondingly, an upper polishing plate is also installed on the frame 1, located above the fabric 18 at the lower polishing plate 14. The upper polishing plate works in conjunction with the lower polishing plate 14 to further brighten the environment in which the fabric 18 is located at the lower polishing plate 14, making it easier for the operator to observe.

[0044] It also includes a tension roller 15, which is located between the first roller group 6 and the first reversing roller 7 along the direction of movement of the fabric 18. In terms of height, the tension roller 15 is located between the first roller group 6 and the first reversing roller 7, and plays the role of tensioning the fabric 18.

[0045] To further illustrate the structure of the first roller group 6, the second roller group 8, and the third roller group 9, it is specified here that the feed roller group 2 is located at the left end of the frame 1, and the discharge roller group 3 is located at the right end of the frame 1. Specifically, the first roller group 6 includes a first roller 61 and a second roller 62, and the third roller group 9 is located between the sixth roller 91 and the seventh roller 92. The first roller 61 and the second roller 62 are arranged side by side and located to the lower right of the feed roller group 2. The tension roller 15 is located above the second roller 62, and the first reversing roller 7 is located above the tension roller 15. The third roller 8... Roller 1 is located to the lower left of the first reversing roller 7; roller 82 is located to the upper left of the third roller 81; roller 83 is located to the upper right of the fourth roller 82 and above the first reversing roller 7; roller 10 is located to the right of the first reversing roller 7, and both are set at the same height; roller 11 is located to the lower right of the second reversing roller 10; roller 91 is located to the lower left of the third reversing roller 11; roller 92 is located to the right of the sixth roller 91; and discharge roller group 3 is located above the seventh roller 92. The specific winding direction of the fabric 18 is as follows: Figure 1 As shown.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model.
