Description

Technical Field

[0001] This utility model belongs to the technical field of fabric color difference detection equipment, and particularly relates to a device for detecting color difference in woven fabric printing. Background Technology

[0002] Fabric color difference detection is a crucial step in the textile printing and dyeing industry, involving the detection and quality control of fabric color differences; color difference is one of the key indicators for measuring textile quality. Accurate color difference detection ensures product color consistency, meeting customer quality requirements. Furthermore, real-time monitoring allows for timely adjustments during production, preventing the mass production of substandard products, thus reducing material waste and production costs. Moreover, color difference detection capabilities help companies respond quickly to market changes and meet consumer demands for personalized and customized products.

[0003] Patent CN116609277A discloses a device for detecting color difference in printed fabrics made of high-twist woven fabrics. The device includes a worktable, a first limiting component, a connecting column, a second limiting component, and a color difference detection mechanism. The worktable contains several rollers. The first limiting component is fixedly connected to the worktable via the connecting column. The first and second limiting components are detachably connected. Both the first and second limiting components have two sliders. The color difference detection mechanism is located on the side of the first limiting component away from the worktable. This solution improves the efficiency and accuracy of color comparison by installing color sensors on a fixed-point color difference monitoring module and a moving color difference monitoring module. The fixed-point color difference monitoring module is fixed horizontally, while the moving color difference monitoring module slides horizontally.

[0004] In existing technologies, a movable color difference detection module is used to facilitate color comparison data, thereby improving the efficiency and accuracy of color comparison. However, the following problems still exist in its overall use: First, in existing technologies, when inspecting fabric, the fabric is placed at an angle on the operating table. When the fabric is tilted, it will slide due to its own gravity, causing wrinkles on the fabric surface, which will affect the detection module's ability to detect color differences. Second, if the fabric surface contains moisture, it will affect the fabric's humidity, which will also affect the accuracy of the fabric color difference detection. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a woven fabric printing and color difference detection device. By setting a slider and clamping block to fix and flatten the fabric, the problem of wrinkles appearing on the surface of the fabric during detection is solved. At the same time, a heating device and electric heating roller are set to dry the fabric, solving the problem that the presence of moisture on the fabric surface affects the accuracy of color difference detection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a testing machine body, inside which is an operating table capable of drying fabric. A base is located at the bottom of the operating table, and a drive plate is slidably mounted inside the base. Multiple connecting rods are rotatably mounted on the end face of the drive plate, and each connecting rod has a slider at one end. These sliders are slidably connected to the base, and clamping blocks are provided on the outer surface of each slider. A mounting plate is slidably mounted above the operating table, and two relatively movable electric heating rollers are rotatably mounted at the bottom of the mounting plate. Multiple color difference inspection devices for detecting color differences are mounted above the two electric heating rollers on the end face of the mounting plate.

[0007] Preferably, the drive plate has multiple connecting bases on its end face, one end of each connecting base is rotatably connected to a connecting rod, the top end face of each base is provided with a first cylinder, the output end of the first cylinder is fixedly connected to the drive plate, and two limiting rods are slidably arranged inside the drive plate, both of which are fixedly connected to the base.

[0008] Preferably, the end face of the base is provided with multiple slide rails, and the multiple slide rails are respectively connected to the slider in a sliding engagement.

[0009] Preferably, the operating table is equipped with a heating device inside, and a blower is provided on one side of the heating device.

[0010] Preferably, the inside of the detection body is provided with two limiting rails, and a movable plate is slidably arranged between the two limiting rails. A threaded rod is rotatably arranged on the bottom end face of the movable plate. An auxiliary rod is arranged on one side of the threaded rod. An adjusting rod is arranged at the bottom end of both the auxiliary rod and the threaded rod. The two adjusting rods are respectively fixedly connected to the two ends of the mounting plate.

[0011] Preferably, two threaded sleeves are slidably disposed below the movable plate. One of the threaded sleeves is threadedly connected to the threaded rod, and the other threaded sleeve is slidably connected to the auxiliary rod. Both sides of the two threaded sleeves are rotatably disposed with drive rods, and movable sleeves are slidably disposed on the outside of the multiple drive rods. The multiple movable sleeves are rotatably connected to both ends of the adjusting rod respectively.

[0012] Preferably, one end of each of the plurality of drive rods is provided with a fixing member, and each of the plurality of fixing members is provided with a mounting shell on an adjacent side. The plurality of mounting shells are arranged in pairs, and each pair of mounting shells is slidably connected to the heating roller. A buffer spring is provided between the heating roller and the mounting shell.

[0013] Preferably, the clamping ends of the plurality of clamping blocks are provided with rubber pads.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0015] (1) By setting up a clamping block, an operating table, an electric heating roller, and a drive rod, this utility model can fix the fabric on the end face of the operating table before color difference detection, preventing the fabric from shifting and affecting the accuracy of fabric detection. The relatively moving electric heating roller and buffer spring can abut against the fabric while flattening the fabric to both sides, thereby preventing wrinkles on the surface of the fabric and further improving the accuracy of color difference detection.

[0016] (2) By setting up an operating table and heating device, as well as a blower and electric heating roller, the present invention can increase the temperature of the operating table surface through the heating device, thereby drying the fabric and preventing the fabric from containing moisture, which would affect the accuracy of color difference detection. At the same time, the heating electric heating roller can be used to iron the surface of the fabric, thereby further reducing the wrinkles on the surface of the fabric. Attached Figure Description

[0023] To enable those skilled in the art to better understand the present invention, 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.

[0024] refer to Figure 1 and Figure 4 A device for detecting printing and dyeing differences in woven fabrics includes a detection body 10. Inside the detection body 10 is an operating table 11 for drying the fabric. Before testing, the fabric sample is placed on the end face of the operating table 11 for processing. Multiple air inlets are provided on the periphery of the operating table 11. A heating device 22 is installed inside the operating table 11, and a blower 21 is located on one side of the heating device 22. By activating the heating device 22 and the blower 21, the interior of the operating table 11 is heated, and the fabric on the end face of the operating table 11 is dried. Simultaneously, the blower 21 causes hot air to circulate within the operating table 11, ensuring that the hot air is fully and evenly distributed inside the operating table 11, preventing concentrated heat from damaging the fabric and thus improving the overall stability of the operating table 11.

[0025] Further reference Figure 2 and Figure 3 The bottom of the operating table 11 is provided with a base 12. Multiple mounting recesses are provided on the end face of the base 12. Each mounting recess contains a slide rail 13, which extends outwards through the outer surface of the base 12. A slider 14 is slidably mounted on the end face of each slide rail 13. The sliders 14 can move synchronously towards the center of the base 12. Each slider 14 has a clamping block 15 on its end face. When the fabric is laid on the end face of the operating table 11, the edges of the fabric are bent downwards against the outer surface of the operating table 11. Between the clamping block 15 and the outer surface of the operating table 11, when the multiple sliders 14 move at the center of the base 12, they will drive the multiple clamping blocks 15 to move centripetally, thereby clamping the downward bending part of the fabric, fixing the fabric, preventing the fabric from shifting, and improving the overall stability of the device. The clamping ends of the multiple clamping blocks 15 are all equipped with heat-resistant rubber pads. By setting heat-resistant rubber pads, the friction between the base 12 and the fabric can be increased, improving the clamping effect. At the same time, it can prevent the clamping blocks 15 from damaging the fabric sample and improve the overall safety of the device.

[0026] It should be noted that the outer contours of the operating table 11 and the base 12 are square, so the distance between each clamping block 15 and the side wall of the operating table 11 is the same, which can ensure that multiple clamping blocks 15 can contact the end face of the base 12 synchronously to achieve the effect of synchronous clamping.

[0027] Further reference Figure 2 and Figure 3 A first cylinder 19 is provided on the inner top end face of the base 12. A drive plate 17 is provided on the output end of the first cylinder 19. Two limit rods 18 are slidably arranged inside the drive plate 17. Both limit rods 18 are fixedly connected to the inner wall of the base 12. Multiple expansion holes are provided on the outer surface of the base 12. The drive plate 17 extends outward from the expansion holes. A connecting base 20 is provided on the extended end face of the drive plate 17. A connecting rod 16 is rotatably arranged on one end of the multiple connecting bases 20. One end of the multiple connecting rods 16 is rotatably connected to the slider 14. When the output end of the first cylinder 19 pushes the drive plate 17 to move downward, the limit rods 18... 8 restricts the movement direction of the drive plate 17, allowing it to move only vertically downwards, thereby improving the stability of the drive plate 17's movement. When the drive plate 17 moves, it drives multiple connecting bases 20 on its end face to move synchronously, thereby pulling the connecting bases 20 downwards. This causes the connecting bases 20 to pull the connecting rod 16, causing the connecting rod 16 to gradually tilt in the vertical direction. The other end of the connecting rod 16 moves closer to the center of the base 12, driving multiple sliders 14 to move synchronously. This causes multiple clamping blocks 15 on the end face of the sliders 14 to move synchronously, thereby clamping the edge of the fabric.

[0028] Further reference Figure 2 and Figure 3 The internal structure of the testing machine body 10 is equipped with two limiting rails 36, and a movable plate 23 is slidably arranged between the two limiting rails 36. A second cylinder is arranged on the end face of the testing machine body 10 above the movable plate 23. The output shaft of the second cylinder is fixedly connected to the movable plate 23. A threaded rod 24 is rotatably arranged on the bottom end face of the movable plate 23. A drive motor is arranged on one end of the threaded rod 24 on the end face of the movable plate 23. The output shaft of the drive motor is connected to the threaded rod 24. An auxiliary rod 25 is arranged on one side of the threaded rod 24. An adjusting rod 2 is arranged at the bottom end of both the auxiliary rod 25 and the threaded rod 24. 8. The length of the adjusting rod 28 is greater than the length of the threaded sleeve 27. A mounting plate 34 is provided between the two adjusting rods 28. Multiple color difference inspection devices 35 for detecting color difference are provided on the end face of the mounting plate 34. When the fabric is subjected to color difference detection, the second cylinder is activated, which pushes the bottom movable plate 23 downward. At the same time, the threaded rod 24 pushes the two adjusting rods 28 downward. The color difference inspection devices 35 between the two adjusting rods 28 move downward synchronously, so that the color difference inspection devices 35 are located on the top end face of the fabric, thereby detecting the color difference of the fabric.

[0029] Further reference Figure 5Before color difference detection of the fabric, the heating roller 32 can be started via electrical connection to heat the roller body. After the heating roller 32 moves downward, it heats and irons the fabric, reducing wrinkles on the fabric surface. Two threaded sleeves 27 are slidably arranged below the movable plate 23. One threaded sleeve 27 is threadedly connected to the threaded rod 24. By starting the drive motor, the threaded rod 24 can be rotated, and the rotation of the threaded rod 24 drives the threaded sleeve 27 to move up and down. The other threaded sleeve 27 is slidably connected to the auxiliary rod 25. Drive rods 26 are rotatably arranged on both sides of the two threaded sleeves 27. After the threaded sleeves 27 move downward, they will drive the drive rods 26 at the bottom to move downward. Movable sleeves 29 are slidably arranged on the outside of the multiple drive rods 26. The multiple movable sleeves 29 are respectively connected to the adjusting rod 28. With the two ends rotatably connected, the drive rod 26 moves under the drive of the threaded sleeve 27, causing the electric heating roller 32 at one end of the drive rod 26 to abut against the surface of the fabric. Due to the restriction of the movable sleeve 29 and the downward movement of the threaded sleeve 27 towards the adjusting rod 28, the two drive rods 26 slide downward along the movable sleeve 29, while simultaneously causing the movable sleeve 29 to rotate. The angle and distance between the bottom ends of the two drive rods 26 gradually increase and become farther apart. As the height of the movable plate 23 increases, it is continuously pushed downward by the second cylinder, causing the two electric heating rollers 32 to move relative to each other along the upper surface of the fabric. This moves the heated electric heating rollers 32 on the upper surface of the fabric, unfolding the fabric. After the two electric heating rollers 32 are unfolded and ironed to both sides, the color difference inspection device 35 at the top can accurately detect the information of the fabric.

[0030] Further reference Figure 5 Each of the multiple drive rods 26 has a fixing member 30 at one end, and each of the multiple fixing members 30 has a mounting shell 31 on one side. The multiple mounting shells 31 are arranged in pairs. Each set of mounting shells 31 has an electric heating roller 32 slidably installed inside. A buffer spring 33 is installed between the electric heating roller 32 and the mounting shell 31. During the process of the multiple electric heating rollers 32 flattening to both sides, the continuous downward movement of the movable plate 23 will cause downward pressure on the electric heating rollers 32. The buffer spring 33 can buffer the pressure and prevent the electric heating rollers 32 from moving downward and damaging the fabric and the operating table 11, thereby improving the overall stability of the device.
