Description

Technical Field

[0001] This utility model relates to the field of color matching light box technology, specifically to a color matching light box for dyeing knitted fabrics. Background Technology

[0002] In industries such as textiles and dyeing, color fastness assessment of materials is performed visually. Color matching and sampling are also conducted to identify color differences and fluorescent substances. This ensures that the sampling, production, quality inspection, and acceptance are carried out under the same standard light source, accurately calibrating the color deviation of the product and ensuring that the color quality of the product meets the requirements. In this case, color matching light boxes are required.

[0003] According to the search, CN214251975U discloses a new type of standard light source color matching light box, including a light box, a dimming structure, and a support structure. The light box has an opening on one side, and a support platform is provided on the side of the opening. A support structure is provided on the support platform. The dimming structure is installed inside the light box near the top.

[0004] The aforementioned utility model, by incorporating an outer cover, a light-transmitting sheet, and different light sources, allows for the electrical connection of the light sources to an external power source during use. By rotating a lever, different colored lights can be rotated to positions coinciding with the light-transmitting sheet, thus projecting the light emitted by different light sources onto the supporting structure for color comparison and observation of fabric color changes. Furthermore, by placing different light sources inside the cylindrical outer cover, space is saved. Different light sources can be obtained simply by rotating the lever, making operation simple and convenient for users. However, the need to arrange multiple light sources of different colors to achieve color switching increases the production and usage costs of the light box.

[0005] Therefore, it is of great importance to design a color matching light box for dyeing knitted fabrics to solve the above-mentioned defects. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example: Please refer to Figures 1-9 This utility model provides a technical solution:

[0033] A color matching light box for dyeing knitted fabric includes a light box body 1, a dimming mechanism 2 installed at the top inside the light box body 1, and a fabric fixing mechanism 3 installed at the bottom inside the light box body 1.

[0034] First, in this embodiment, the specific structure of the dimming mechanism 2 is as follows:

[0035] The dimming mechanism 2 includes a switching cylinder 201 rotatably connected to the top of the interior of the light box body 1. A lampshade 202 is fixedly installed inside the switching cylinder 201 at the top of the interior of the light box body 1. A high-brightness LED 203 is fixedly installed inside the top of the lampshade 202. Multiple sets of light filters 204 are embedded at equal intervals on the inner sidewall of the lampshade 202. A transmission gear 205 is fixedly installed on the outer side of the lampshade 202. A rotating shaft 206 is rotatably connected to the top of the front of the light box body 1. The rear end of the rotating shaft 206 meshes with the transmission gear 205 through a drive gear 207. When it is necessary to change the color of the light source, the operating handle 21 is rotated. 0. The operating handle 210 drives the rotating shaft 206 and the drive gear 207 to rotate, which in turn drives the transmission gear 205 and the lampshade 202 to rotate. When the lampshade 202 rotates, a single high-brightness LED 203 is used as the light source. Combined with multiple sets of filters 204 on the inner wall of the lampshade 202, different filters 204 can be selected by rotating the lampshade 202 to achieve the switching of light source color. Compared with the traditional design that requires the arrangement of multiple different color light sources, this solution significantly reduces the production and use cost of the light box. At the same time, since the switching of the filters 204 is simple and quick, the flexibility and convenience of using the light box are improved.

[0036] Furthermore, the front end of the switching cylinder 201 is rotatably connected to the light box body 1 via the bearing 208, and the rear end of the lampshade 202 is fixedly connected to the light box body 1. The inner side of the lampshade 202 is coated with a barium sulfate-based diffuse reflection coating 209. The front end of the switching cylinder 201 is rotatably connected to the light box body 1 via the bearing 208, allowing the switching cylinder 201 to rotate freely inside the light box body 1. The rear end of the lampshade 202 is fixedly connected to the light box body 1 to ensure that the lampshade 202 remains stable during rotation. The barium sulfate-based diffuse reflection coating 209 is coated on the inner side of the lampshade 202. This coating can effectively improve the diffuse reflection effect of light, so that the light emitted from the high-brightness LED light 203 can be more evenly distributed inside the lampshade 202 after passing through the filter 204, avoiding direct light and local overbrightness. This not only improves the lighting effect of the color matching light box, but also helps users to more accurately observe and analyze the color of the fabric.

[0037] Then, an operating handle 210 is fixedly connected to the front end of the rotating shaft 206. A locking gear 211 is fixedly installed on the outside of the operating handle 210. A pull rod 212 is slidably connected to the front of the light box body 1 and outside the locking gear 211. The top end of the pull rod 212 meshes with the locking gear 211 through a locking tooth block 213. A spring 214 is sleeved on the outside of the pull rod 212. The right end of the locking tooth block 213 is slidably connected to the outside of the light box body 1 through a slide rod 215. When switching the light source color, first pull the pull rod 212 to separate the locking tooth block 213 from the locking gear 211. After rotating the operating handle 210 to rotate the switching cylinder 201 to the desired position, release the pull rod 212. The spring 214 pushes the locking tooth block 213 to mesh with the locking gear 211, locking the current position to avoid misoperation.

[0038] Furthermore, indicator lines 216 are provided on the front of the switching cylinder 201 at positions corresponding to the multiple sets of filters 204. An indicator needle 217 is fixedly connected to the front of the light box body 1 below the switching cylinder 201. By observing the corresponding positions of the indicator lines 216 on the front of the switching cylinder 201 and the indicator needle 217 on the front of the light box body 1, different indicator lines 216 are used in actual use with different colors corresponding to the filters 204, providing intuitive visual feedback and making it easy for users to confirm the currently used filter 204.

[0039] The lightbox body 1 has a door 101 hinged to the front, and a door handle 102 is fixedly connected to the bottom of the front of the door 101. The door 101 is hinged to the front of the lightbox body 1 to facilitate opening and closing to access the internal components. The door handle 102 is fixedly connected to the bottom of the front of the door 101 for user operation.

[0040] Furthermore, the fabric fixing mechanism 3 includes a mounting base 301 fixedly installed inside the bottom of the light box body 1. A lifting rod 302 is fixedly connected to the top of the mounting base 301. A first fixing plate 303 is fixedly installed at the top of the lifting rod 302. Connecting rods 304 are fixedly connected to both the left and right ends of the first fixing plate 303. A second fixing plate 305 is fixedly connected to the bottom ends of the two sets of connecting rods 304. The fabric is fixed between the first fixing plate 303 and the second fixing plate 305. Different colors of light above the fabric are projected onto its outer side to compare and observe the changes in the fabric color.

[0041] Secondly, the lifting rod 302 consists of a support cylinder 306 and an adjusting rod 307. The support cylinder 306 is fixedly connected to the top of the mounting base 301, and the adjusting rod 307 is slidably connected to the inner side of the support cylinder 306. A tightening sleeve 308 is fixedly connected to the top of the support cylinder 306, and a locking sleeve 309 is fitted on the outer side of the adjusting rod 307. The locking sleeve 309 is threadedly connected to the tightening sleeve 308. A connector 310 is rotatably attached to the top of the adjusting rod 307. The connector 310 is fixedly connected to the first fixing plate 303, and the connector 310 is connected to the adjusting rod 307 via a connecting shaft 311. The connecting shaft 311 is rotatably connected to a first locking sleeve 312 threadedly connected to its right end. When adjusting the height of the lifting rod 302, the sliding adjusting rod 307 is positioned within the support cylinder 306. The locking sleeve 309 is rotated to thread it onto the tightening sleeve 308, thereby fixing the position of the adjusting rod 307 and adjusting the light-receiving height of the fabric. Through the connecting shaft 311 and the first locking sleeve 312, the angle of the first fixing plate 303 relative to the lifting rod 302 can be adjusted, thereby adjusting the light-receiving angle of the fabric and further improving the accuracy and ease of operation of color detection.

[0042] Finally, a fixing clamp 313 is hinged to both the first fixing plate 303 and the second fixing plate 305. A locking shaft 314 is fixedly connected to the right end of both the first fixing plate 303 and the second fixing plate 305 at the position corresponding to the fixing clamp 313. A second locking sleeve 315 is threaded onto both sets of locking shafts 314. The fabric is placed between the first fixing plate 303 and the second fixing plate 305, and the fixing clamp 313 is rotated to make it come into close contact with the fabric. It is then fixed by the second locking sleeve 315 on the locking shaft 314, thereby clamping both ends of the fabric to achieve fixation.

[0043] In this embodiment, the specific implementation scenario is as follows: When it is necessary to change the color of the light source, first pull the lever 212 to disengage the locking block 213 from the locking gear 211, then rotate the operating handle 210. The operating handle 210 drives the rotating shaft 206 and the drive gear 207 to rotate, thereby driving the transmission gear 205 and the lampshade 202 to rotate. When the lampshade 202 rotates, a single high-brightness LED lamp 203 is used as the light source. Combined with multiple sets of filters 204 on the inner wall of the lampshade 202, different filters 204 can be selected by rotating the lampshade 202 to achieve the switching of the light source color. Then, open the box door 101 and place the fabric between the first fixing plate 303 and the second fixing plate 305. Rotate the fixing clamp 313 to make it in close contact with the fabric and fix it by the second locking sleeve 315 on the locking shaft 314, thereby... The fabric is fixed by clamping both ends. When adjusting the height of the lifting rod 302, the sliding adjusting rod 307 is positioned inside the support cylinder 306. The locking sleeve 309 is rotated to connect with the tightening sleeve 308, thereby fixing the position of the adjusting rod 307 and adjusting the light-receiving height of the fabric. Through the connecting shaft 311 and the first locking sleeve 312, the angle of the first fixing plate 303 relative to the lifting rod 302 can be adjusted, thereby adjusting the light-receiving angle of the fabric. Different colors of light are projected onto the outside of the fabric for color comparison and observation of fabric color changes. The entire operation process is simple and convenient. This utility model significantly reduces the production and use costs of the light box through design, improves the flexibility and convenience of the light box, and can adjust the light-receiving height and angle of the fabric, thereby improving the accuracy of color detection.
