Description

Technical Field

[0001] This utility model belongs to the field of fabric testing equipment and relates to a fabric color matching light box. Background Technology

[0002] In industries such as textiles, dyeing, and garment manufacturing, accurate fabric color determination is crucial for product quality control and ensuring color consistency. Fabric color matching light boxes, as key equipment for precise color matching, are widely used.

[0003] However, traditional fabric color matching light boxes have several shortcomings. First, the platform angle for placing the fabric is fixed during the color matching process, making it impossible to flexibly adjust according to actual needs. This results in difficulty observing the fabric color from all angles, leading to poor color matching results. Second, regarding fabric fixation, there is a lack of effective clamping and limiting devices, causing the fabric to easily shift during color matching, affecting accuracy. Furthermore, there is no dedicated smoothing device, making it difficult to eliminate wrinkles on the fabric. Wrinkles alter light reflection and absorption, thus interfering with the color matching results. In addition, external light can easily enter the light box, interfering with the standard light source inside and reducing color matching accuracy.

[0004] To address the aforementioned problems, a series of improvement attempts have been made, but most of these only optimized single issues and failed to improve the overall practicality of the color matching lightbox. This utility model, a fabric color matching lightbox, achieves multifaceted innovation by incorporating various functional components, effectively overcoming the shortcomings of existing technologies and significantly improving the efficiency and accuracy of fabric color matching.

[0027] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the fabric color matching light box proposed by this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, used only to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.

[0028] Reference Figure 1-9 A fabric color matching light box includes a light box body 1, an illumination light source 13, a placement plate 2, and two square rods 31. Two symmetrically arranged box doors 11 are hinged to the front side of the light box body 1. The illumination light source 13 is fixedly installed on the top inner wall of the light box body 1. A control panel 12 is fixedly installed on the bottom inner wall of the light box body 1 at the front position. Support pins 21 are fixedly installed on both sides of the placement plate 2. The two support pins 21 are located on the same axis and are rotatably connected to the inner walls of both sides of the light box body 1, respectively.

[0029] A motor 212 is fixedly installed on the inner wall of one side of the light box body 1. A worm gear 213 is axially fixedly connected to the output shaft of the motor 212. A worm wheel 211 is fixedly sleeved on the support pin 21 near the motor 212. The worm gear 213 meshes with the worm wheel 211, which can adjust the tilt angle of the placement plate 2 as needed, and at the same time maintain good stability after adjustment.

[0030] A pointer 22 is fixedly installed on the worm gear 211. A protractor 221 is fixedly installed on the inner wall of one side of the light box body 1, with the support pin 21 as the center. The pointer 22 is adapted to the protractor 221, so that the operator can understand the tilt angle of the placement plate 2.

[0031] Strip plates 3 are fixedly installed at both ends of the top side of the placement plate 2. Slide grooves are opened on the side of the two strip plates 3 that are close to each other. The two ends of the two square rods 31 are slidably installed in the corresponding slide grooves. Slide rods 311 are slidably installed at both ends of the two square rods 31, and the two square rods 31 are arranged parallel to each other. The four slide rods 311 are fixedly installed in the two slide grooves. Two springs 312 are fixedly installed on the top inner wall of the slide grooves. The bottom ends of the two springs 312 are fixedly installed on the corresponding square rods 31, and the springs 312 are movably sleeved on the outside of the corresponding slide rods 311, which can provide stable support and guidance for the square rods 31.

[0032] Two sliders 321 are slidably installed on each of the two square rods 31. Each of the four sliders 321 has a pressure plate 32 fixedly installed on its bottom side, which abuts against the top side of the placement plate 2. This allows for pressing and limiting of the fabric placed at different positions on the placement plate 2 as needed.

[0033] Two sliders 331 are slidably mounted on each of the two square rods 31. A smoothing plate 33 is fixedly mounted on the bottom side of each of the four sliders 331, which abuts against the placement plate 2. The sliders 331 can be controlled to drive the smoothing plate 33 to smooth the fabric placed on the placement plate 2 as needed, so as to avoid wrinkles affecting normal color matching. Two guide plates 332 are slidably mounted on the upper and lower sides of the two square rods 31. A spring 333 is fixedly mounted on the side of the guide plate 332 away from the square rod 31, and the spring 333 is fixedly connected to the sliders 331. This allows the sliders 331 and the smoothing plate 33 to have good stability when moving. At the same time, it can automatically reset when not in use, and can smooth and remove wrinkles from the fabric without affecting the normal pressing limit of the pressure block.

[0034] In this embodiment, in order to facilitate the operation of the pressure plate 32 and the sliding plate 33, a handle and a lifting handle are fixedly installed on the top side of the first slider 321 and the top side of the second slider 331, respectively.

[0035] In this embodiment, in order to effectively block the light that shines obliquely from above the box door 11 and prevent the light from shining directly on the fabric placed on the placement plate 2, thereby reducing the influence of light on the color comparison of the fabric and improving the accuracy of color comparison, the fan-shaped design of the light shield 111 allows it to automatically retract and extend along with the opening and closing of the box door 11 while providing a light shielding effect. The rear top of the box door 11 is fixedly installed with a fan-shaped light shield 111.

[0036] Working principle:

[0037] Tilt adjustment of the placement plate: When it is necessary to adjust the angle of the placement plate 2, start the motor 212 on the inner wall of one side of the light box body 1. The output shaft of the motor 212 drives the worm gear 213 to rotate. Since the worm gear 213 meshes with the worm wheel 211 fixedly sleeved on the support pin 21, the worm wheel 211 rotates accordingly, which in turn drives the support pin 21 to rotate. Because the support pins 21 on both sides of the placement plate 2 are rotatably connected to the inner walls on both sides of the light box body 1, the tilt angle of the placement plate 2 is adjusted. The pointer 22 on the worm wheel 211 will rotate with the worm wheel 211. The operator can accurately know the tilt angle of the placement plate 2 by observing the position of the pointer 22 on the protractor 221. After the motor 212 stops working, the self-locking characteristic of the worm gear mechanism can keep the placement plate 2 at the adjusted angle and maintain stability.

[0038] Fabric clamping limit: When placing the fabric, according to the size and position of the fabric, manually push the slider 321 to slide on the square rod 31. The pressure plate 32 on the bottom side of the slider 321 moves accordingly until the pressure plate 32 presses the fabric onto the placement plate 2, thereby fixing the fabric in different positions and preventing the fabric from shifting during the color matching process.

[0039] Fabric smoothing operation: To avoid fabric wrinkles affecting color matching, slider 2 331 can be pushed to slide on square rod 31. The smoothing plate 33 on the bottom side of slider 2 331 moves accordingly to smooth the fabric placed on the placement plate 2. During the movement of slider 2 331, guide plate 332 cooperates with spring 2 333 to provide guidance and stable support for the movement of slider 2 331 and smoothing plate 33. After the operation is completed and slider 2 331 is released, spring 2 333 will cause slider 2 331 and smoothing plate 33 to automatically reset. It is worth noting that this design can complete the fabric smoothing operation while the pressure plate 32 keeps the fabric pressed.

[0040] Square rod stable support: The two ends of the square rod 31 slide in the groove of the strip plate 3. The slide rod 311 and the spring 312 provide stable support and guidance for the square rod 31. The spring 312 is sleeved on the outside of the slide rod 311 to ensure that the square rod 31 remains stable when moving or carrying the fabric.

[0041] Light-blocking operation: When the box door 11 is opened, the fan-shaped light-blocking plate 111 on the top rear side of the box door 11 opens accordingly, blocking the light that shines obliquely from above the box door 11, preventing the light from shining directly on the fabric, reducing the interference of external light on the color comparison of the fabric, and improving the accuracy of color comparison. When the box door 11 is closed, the light-blocking plate 111 automatically retracts with the box door 11.

[0042] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.
