[0002] In the textile industry, weft-knitted fabric is an important textile material, and its quality directly affects the quality and performance of the final product. After weaving and before entering the finished product warehouse, the semi-finished fabric usually needs to undergo strict appearance quality inspection to identify common defects such as stains, broken warp, broken weft, skipped stitches, and holes.

[0003] Traditional inspection methods primarily rely on manual visual inspection. Operators need to unfold the fabric on a specific inspection table and inspect it section by section based on experience and concentration. This method has many drawbacks: First, manual inspection is inefficient and labor-intensive, making it difficult to meet the demands of modern large-scale production; second, prolonged work can easily lead to visual fatigue, resulting in missed or false detections, and unstable and inconsistent inspection results; third, manual inspection lacks objective data recording, making it difficult to conduct quality traceability and statistical analysis. No solutions have yet been proposed to address these technical problems. Utility Model Content

[0004] To address the problems in related technologies, this utility model proposes a weft-knitted fabric semi-finished product inspection device to overcome the aforementioned technical problems existing in the prior art. The purpose of this utility model is to enable the camera to cover the entire fabric surface area on the inspection table for rapid and comprehensive scanning, and to accurately locate suspected defect points for verification at any time, thereby improving inspection efficiency and flexibility, completely avoiding visual fatigue and missed detection problems caused by manual inspection, ensuring that the camera can always capture the clearest images at the best angle and depth of field, effectively improving the accuracy of defect identification, avoiding ambient light interference, and ensuring the consistency of inspection conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a weft-knitted fabric semi-finished product testing device, including a testing box, a workbench inside the testing box, a door connected to the front end of the testing box via a hinge, a display screen on one side of the door, a camera connected to the top of the inside of the testing box via a moving mechanism, a testing platform below the camera, and the testing platform connected to the workbench via an adjustment mechanism.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Example Please see Figure 1-4 This utility model proposes a technical solution for a weft-knitted fabric semi-finished product testing device: The device includes a testing box 1, specifically made of stainless steel to extend its service life. A workbench 2 is installed inside the testing box 1, specifically serving a supporting function. A door 3 is connected to the front of the testing box 1 via a hinge, specifically forming a closed space with the door 3, avoiding ambient light interference and ensuring consistent testing conditions. A display screen 4 is installed on one side of the door 3, specifically displaying the testing data and improving convenience. A camera 5 is connected to the top of the testing box 1 via a moving mechanism, specifically collecting data from the weft-knitted fabric. A testing platform 6 is installed below the camera 5, specifically placing the weft-knitted fabric to be tested on the testing platform 6. The testing platform 6 is connected to the workbench 2 via an adjustment mechanism. The moving mechanism can adjust the lateral position and height of the camera 5, and the adjustment mechanism can adjust the lateral position of the testing platform 6. The moving mechanism includes a drive motor 7, a screw 8, a movable plate 9, a drive motor 10, a screw 11, and a base 12. Drive motor 7 is fixedly installed inside the top of the detection box 1. Both ends of screw 8 are connected to drive motor 7 and the detection box 1, respectively. Movable plate 9 is sleeved on screw 8 and threadedly connected to it. Both ends of movable plate 9 are movably connected to the inner walls of both sides of the detection box 1. Drive motor 10 is fixedly installed on movable plate 9. Both ends of screw 11 are connected to drive motor 10 and movable plate 9, respectively. Base 12 is sleeved on screw 11 and threadedly engaged with it. Base 12 and movable plate 9 are movably connected. Camera 5 is fixedly installed on base 12. Specifically, through... The drive motor 7 is started, which drives the screw 8 fixedly connected to it to rotate clockwise or counterclockwise. When the screw 8 rotates, it drives the movable plate 9, which is threaded to it, to move left and right, thereby adjusting the lateral position of the camera 5. The drive motor 10 is started, which drives the screw 11 fixedly connected to it to rotate clockwise or counterclockwise. When the screw 11 rotates, it drives the base 12, which is threaded to it, to move up and down, so as to adjust the height of the camera 5. One end of the screw 8 is fixedly connected to the output end of the drive motor 7, and the other end of the screw 8 is movably connected to the detection box 1. One end of the screw 11 is fixedly connected to the output end of the drive motor 10, and the other end of the screw 11 is movably connected to the movable plate 9.

[0016] Please see Figure 2-4 As shown, the adjustment mechanism further includes a drive motor 313 and a screw 314. The drive motor 313 is fixedly installed on the worktable 2. The two ends of the screw 314 are respectively connected to the drive motor 313 and the worktable 2. The bottom end of the detection table 6 is sleeved on the screw 314 and threadedly engaged with the screw 314.

[0017] In this embodiment, one end of the screw 3 14 is fixedly connected to the output end of the drive motor 3 13, and the other end of the screw 3 14 is movably connected to the worktable 2. By starting the drive motor 3 13, the screw 3 14 fixedly connected to it is driven to rotate clockwise or counterclockwise. When the screw 3 14 rotates, it drives the detection table 6, which is threaded with it, to move laterally, so as to facilitate the adjustment of the position of the detection table 6.

[0018] Please see Figure 2-3 As shown, the top of the testing platform 6 is further provided with a boss 15.

[0019] In this embodiment, the boss 15 serves to support the weft-knitted fabric.

[0020] Please see Figure 1 As shown, a controller 16 is further provided below the workbench 2.

[0021] In this embodiment, the controller 16 is electrically connected to drive motor 7, drive motor 10 and drive motor 13 respectively, so that the controller 16 can control drive motor 7, drive motor 10 and drive motor 13 respectively.

[0022] Please see Figure 2-4 As shown, further, guide rails 17 are provided on both sides of the movable plate 9. The guide rails 17 are fixedly installed on the detection box 1. Movable blocks 18 are movably connected to the guide rails 17. The movable blocks 18 and the movable plate 9 are fixedly connected.

[0023] In this embodiment, when the movable plate 9 moves under the action of the drive motor 7, it drives the movable block 18 to move on the guide rail 17, thereby improving the stability of the movement of the movable plate 9.

[0024] Please see Figure 1 As shown, a visual observation window is provided on the door 3, and a handle is installed on the door 3.

[0025] In this embodiment, the internal state of the cabinet door 3 can be observed through a visual observation window, and the cabinet door 3 can be easily opened through a handle.

[0026] The working principle of this utility model: The operator opens the door 3 using the handle on the door 3, lays the semi-finished weft-knitted fabric to be tested flat on the protrusion 15 on the top of the testing table 6, closes the door 3, and starts the device through the controller 16 below the workbench 2. The enclosed space formed by the testing box 1 and the door 3 effectively isolates the interference of external ambient light.

[0027] The controller 16 issues a command to start drive motor 7, which drives screw 8, fixedly connected to its output end, to rotate. Since the movable plate 9 is threadedly engaged with screw 8 and its sides are constrained to the fixed guide rail 17 by movable blocks 18, the rotational motion of screw 8 is converted into stable, linear motion of the movable plate 9 along the length of the detection box 1. The controller 16 then starts drive motor 10, fixedly mounted on the movable plate 9, which drives screw 11, fixedly connected to its output end, to rotate. The base 12, threadedly engaged with screw 11, then moves linearly along its height on the movable plate 9. Through the coordinated operation of drive motors 7 and 10, the camera 5, fixedly mounted on the base 12, can move arbitrarily in the two-dimensional plane above the detection table 6, achieving a seamless scan of the entire fabric surface. Simultaneously, by controlling the height movement of the base, the distance between the camera 5 and the fabric surface can be finely adjusted to obtain the optimal shooting focal length and image clarity.

[0028] If a specific area of ​​the fabric needs to be finely inspected or the position of the fabric relative to the camera 5 needs to be adjusted, the adjustment mechanism can be activated. The controller 16 controls the drive motor 3 13 to operate. The drive motor 3 13 drives the screw 3 14, which is fixedly connected to its output end, to rotate. Since one end of the bottom of the inspection table 6 is threadedly engaged with the screw 3 14, the rotation of the screw 3 14 will drive the inspection table 6 to move along its own plane, thereby achieving fine adjustment of the fabric position and making the area to be inspected precisely located directly below the camera 5.

[0029] With the cooperation of the moving and adjusting mechanisms, camera 5 acquires high-speed, clear image data of the fabric surface. The acquired image data is transmitted to the control system for processing and analysis to identify defects. The status, results, and analysis data of the inspection process can be displayed in real time on the display screen 4 on one side of the door 3. Operators can also directly observe the internal inspection status through the visual observation window on the door 3.
