Description
Technical Field
[0001] This utility model relates to the field of textile equipment technology, and in particular to a dyeing uniformity testing device. Background Technology
[0002] In the textile and dyeing industries, fabric dyeing uniformity is one of the key indicators for measuring product quality. Uniformly dyed fabrics not only have an attractive appearance but also exhibit more stable performance during subsequent processing and use, better meeting market and customer demands. With consumers' increasing demands for textile quality and intensifying market competition, accurately and efficiently inspecting fabric dyeing uniformity has become a crucial step for enterprises to ensure product quality and enhance competitiveness.
[0003] In recent years, some enterprises have begun to use simple instruments to assist in testing, such as colorimeters. Although colorimeters can quantify color differences to a certain extent, they can only measure local points on the fabric and are difficult to conduct comprehensive and continuous testing on the entire fabric. They are also difficult to reflect the overall dyeing uniformity of the fabric. Moreover, these traditional testing methods often require frequent manual sampling and operation, which cannot be effectively integrated with the production process and makes it difficult to achieve real-time monitoring and online testing of the fabric dyeing process. Therefore, this application provides a dyeing uniformity testing device to meet the needs. Utility Model Content

[0009] Optionally, the number of limiting plates is two sets, and they are symmetrically distributed on the inner side of the mounting frame.
[0010] Optionally, the clamping assembly includes a connecting frame fixedly connected to the inner side of the support frame, a slide rod fixedly connected to the inner side of the connecting frame, an X-shaped movable frame slidably connected to the outer side of the slide rod, and a spring fixedly connected between the X-shaped movable frame and the inner side of the connecting frame.
[0011] Optionally, a fixing plate is fixedly connected to the bottom of the X-shaped movable frame, and a roller is rotatably connected to the inner side of the fixing plate.
[0012] Optionally, the number of rollers is two sets, and they are symmetrically distributed at the bottom of the X-shaped movable frame.
[0013] Compared with the prior art, this utility model has at least the following beneficial effects:
[0014] In the above scheme, by setting a limiting component, the distance between the limiting plates can be adjusted by turning the handle according to the different sizes of the fabric, so that fabrics of different sizes are kept in the center position during transmission, which facilitates subsequent scanning and acquisition, and makes the dyeing inspection more comprehensive and specific.

[0030] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a dyeing uniformity inspection device, including a conveyor 1, a servo motor 2 fixedly connected to the side of the conveyor 1, a support frame 3 fixedly connected to the top of the conveyor 1, a limiting component 7 for ensuring that fabrics of different sizes remain in the center position during transmission, the limiting component 7 being connected to the support frame 3, a pressing component 8 for pressing the fabric in the camera scanning area, the pressing component 8 being connected to the support frame 3, an image analyzer 4 fixedly connected to the top of the support frame 3, an illumination lamp holder 5 fixedly connected to the inner side of the support frame 3, and a line scan camera 6 fixedly connected to the inner side of the illumination lamp holder 5. The dyeing uniformity inspection device provided by this application not only The dyed fabric can be scanned and acquired using a line scan camera 6. The acquired fabric images can be analyzed using an image analyzer 4 to calculate color parameter differences and dyeing unevenness indices in different parts of the fabric. The dyeing test results are presented in intuitive charts and data. The limiting component 7 keeps fabrics of different sizes in the center area during transport, ensuring that subsequent scanning and acquisition are not affected. At the same time, the pressing component 8 presses the fabric in the scanning area to prevent wrinkles from appearing during scanning, thus avoiding affecting the scanning imaging results. Meanwhile, the rotating roller 806 does not affect the transport of the fabric, facilitating the transfer of the fabric and improving the efficiency of dyeing inspection.
[0031] In this embodiment, as Figures 1 to 4 As shown, the limiting assembly 7 includes a movable plate 701 fixedly connected to the front of the support frame 3. A mounting frame 702 is fixedly connected to the end of the movable plate 701 away from the support frame 3. A limiting rod 703 is fixedly connected to the inner side of the mounting frame 702. A crank 704 is rotatably connected to the outer side of the mounting frame 702. A bidirectional threaded rod 705 is fixedly connected to one end of the crank 704 extending to the inner side of the mounting frame 702. A moving block 706 is threadedly connected to the outer side of the bidirectional threaded rod 705. A limiting plate 707 is fixedly connected to the inner side of the moving block 706. There are two sets of limiting plates 707, symmetrically distributed on the inner side of the mounting frame 702. At this time, by turning on the servo motor 2, the inner conveyor belt of the conveyor 1 is made to rotate at a uniform speed. The dyed fabric is placed on one side of the conveyor 1. By pressing down the movable plate 701, the bottom of the mounting frame 702 is brought close to the conveyor belt. At the same time, the rocker handle 704 is turned so that the moving block 706 drives the limiting plate 707 to move along the thread. According to the different sizes of the fabric, the appropriate spacing is adjusted according to the scale on the top of the mounting frame 702 so that the fabric can be conveyed according to the gap between the two sets of limiting plates 707. This makes it easy to keep the fabric in the center position during conveying, so that subsequent scanning and acquisition are not affected, and the dyeing inspection is more comprehensive and specific.
[0032] In this embodiment, as Figures 1 to 5As shown, the clamping assembly 8 includes a connecting frame 801 fixedly connected to the inner side of the support frame 3. A slide rod 802 is fixedly connected to the inner side of the connecting frame 801, and an X-shaped movable frame 804 is slidably connected to the outer side of the slide rod 802. A spring 803 is fixedly connected between the slide rod 802 and the inner side of the connecting frame 801. A fixing plate 805 is fixedly connected to the bottom of the X-shaped movable frame 804, and a roller 806 is rotatably connected to the inner side of the fixing plate 805. There are two sets of rollers 806, symmetrically distributed at the bottom of the X-shaped movable frame 804. When the fabric reaches the scanning area of the line scan camera 6, the brightness is increased by turning on the lighting fixture 5, so that the line scan camera 6 can acquire clear, high-quality images. The scanning speed of the camera is matched with the conveying speed of the fabric, ensuring that image information can be acquired completely and continuously during the uniform movement of the fabric. The process involves using the spring 803 inside the connecting frame 801 to press the X-shaped movable frame 804, causing the X-shaped movable frame 804 to press down on the fixed plate 805. This drives the two sets of rollers 806 to press the dyed fabric in the scanning area below. Simultaneously, the rollers 806 rotate while pressing, without affecting the uniform conveying of the fabric. This significantly improves the dyeing inspection efficiency, eliminating the need for manual comparison, which is inefficient. Finally, the image analyzer 4 analyzes the image and assesses the uniformity of fabric dyeing based on the distribution of color parameters. Uniformly dyed fabrics appear as having a relatively consistent color distribution in the image, while unevenly dyed areas show color differences. By analyzing these color differences, the dyeing uniformity can be quantitatively assessed, thus achieving the effect of inspecting whether the fabric dyeing is uniform.
[0033] The working principle of the technical solution provided by this utility model is as follows:
[0034] In use, by turning on the servo motor 2, the inner conveyor belt of the conveyor bed 1 rotates at a uniform speed. The dyed fabric is placed on one side of the conveyor bed 1. By pressing down the movable plate 701, the bottom of the mounting frame 702 is brought close to the conveyor belt. At the same time, the rocker handle 704 is turned, causing the moving block 706 to move the limiting plate 707 along the thread. Depending on the size of the fabric, the appropriate spacing is adjusted according to the scale on the top of the mounting frame 702, allowing the fabric to be conveyed according to the gap between the two sets of limiting plates 707. This ensures that the fabric is kept in the center during conveying, facilitating subsequent scanning and acquisition without interference, and making the dyeing inspection more comprehensive and specific. When the fabric reaches the scanning area of the line scan camera 6, the brightness is increased by turning on the lighting fixture 5, allowing the line scan camera 6 to acquire clear, high-quality images. The scanning speed of the camera is matched with the conveying speed of the fabric to ensure that... During the uniform movement of the fabric, image information can be collected completely and continuously. At the same time, the spring 803 inside the connecting frame 801 squeezes the X-moving frame 804, causing the X-moving frame 804 to press down on the fixed plate 805. This drives the two sets of rollers 806 to press the dyed fabric in the scanning area below. As the conveyor belt moves, the rollers 806 rotate while pressing, without affecting the uniform conveying of the fabric. Compared with manual comparison, this greatly improves the efficiency of dyeing inspection. Finally, the image analyzer 4 is used to analyze the image and evaluate the uniformity of fabric dyeing based on the distribution of color parameters. Because uniformly dyed fabric appears to have a relatively consistent color distribution in the image, while unevenly dyed areas will show color differences. By analyzing these color differences, the uniformity of dyeing can be quantitatively evaluated, thereby achieving the effect of inspecting whether the fabric dyeing is uniform.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
