Description

Technical Field

[0001] This application relates to the technical field of testing stations, and in particular to a color difference testing station for decorative paper. Background Technology

[0002] Decorative paper is placed under the top layer of paper in the product structure. Its main functions are to provide decorative patterns and to cover the bottom layer of adhesive to prevent it from seeping through. During the production process of decorative paper, color matching is required to ensure its quality. The color matching of decorative paper is usually carried out by comparing the color of the paper with the sample in a standard light source box.

[0003] The existing publication number CN218157524U, entitled "A Standard Light Source Color Difference Measurement Test Stand for Decorative Paper Production," relates to the field of decorative paper production. It includes a workbench and a standard light source box. An observation port is provided on one side of the standard light source box, and a hollow observation column is inclined towards the bottom of the box at the observation port. A baffle plate is provided at the entrance of the observation column, and multiple sets of calibration strips are provided on its inner wall. A placement plate with its surface orthogonal to the inner wall plane of the observation column is placed inside the standard light source box. The placement plate is rotatably connected via a rotating shaft, and an adjustment knob is connected to one end of the shaft. This invention allows for convenient adjustment of the angle of the placement plate by rotating the adjustment knob on the placement plate's rotating shaft, thereby accurately controlling the observer's viewing angle and the angle between the color chart and the sample on the placement plate. This facilitates observation of the color chart and sample from different accurate angles, improving the accuracy of colorimetric comparison.

[0004] Regarding the aforementioned technologies, the inventors discovered that when the decorative paper testing station performs color difference testing, the length of the testing table is limited. When testing large areas of decorative paper, it is impossible to lay the entire surface on the testing station, which makes it easy for large areas of decorative paper to bend and warp. This causes light reflection on the bent and warped surfaces during the testing of decorative paper, affecting the accuracy of color difference testing. Utility Model Content

[0005] To overcome the limitations of existing testing table sizes, which prevent large areas of decorative paper from being fully laid on the testing table, causing bending and warping during testing, resulting in light reflection on the bent and warped surfaces and affecting the accuracy of color difference detection, this application provides a color difference detection table for decorative paper.

[0006] The color difference detection station for decorative paper provided in this application adopts the following technical solution:

[0007] A color difference detection table for decorative paper includes a detection table, an unwinding component, a rewinding component, and a lighting component. Perforated plates are horizontally fixed on both the front and rear sides of the upper part of the detection table, and a rotating plate is horizontally mounted on the perforated plates. Multiple pressure rollers are horizontally rotatably connected to the vertical end face of the rotating plate near the detection table. A guide rod frame is vertically fixed on the bottom surface of the rotating plate, and the guide rod frame is slidably inserted through the perforated plate. A downward pressure spring is vertically fixed on the bottom surface of the guide rod frame, and the top end of the downward pressure spring is fixed to the bottom surface of the perforated plate. Unwinding and rewinding components are respectively located on the rear sides of both end faces of the detection table, and a lighting component is located on the top surface of the rotating plate on the rear side of the detection table.

[0008] By adopting the above technical solution, the decorative paper roll to be tested is inserted into the unwinding device on one side of the testing table. The decorative paper roll is unwound and laid on the top surface of the testing table. The decorative paper passes through the pressure rollers on the front and rear sides of the testing table, and then is wound up on the winding device on the other side of the testing table. During testing, the decorative paper is driven by the deformation force of the downward pressure spring, which drives the guide rod frame at the bottom of the rotating plate to slide vertically down the perforated plate, causing the pressure rollers to press against the decorative paper to maintain stability during testing. This avoids the problem of bending and warping that easily occurs when testing large areas of decorative paper, thus ensuring the stability of the decorative paper during testing. At the same time, in order to ensure continuous testing of long decorative paper, the unwinding and winding devices are used to wind the paper through the testing table, which facilitates continuous testing of large-length and large-volume decorative paper.

[0009] Optionally, both the unwinding and rewinding components include a rotating base, which is fixed to the rear side of the side end face of the testing table. A rotating rod is horizontally rotatably connected to the rotating base, and a decorative paper roll is inserted into the rotating rod.

[0010] By adopting the above technical solution, a central pivot is fixed to the rear side of the test table, and a rotating rod connected to the pivot facilitates the rotation and unwinding of the decorative paper roll.

[0011] Optionally, a motor is horizontally fixed on the rotator, and the output end of the motor is fixed to the end of the rotating rod.

[0012] By adopting the above technical solution, the motor on the turntable is started to drive the rotating rod to rotate on the turntable, thereby driving the unwinding and rewinding parts to rewind the paper through the inspection table, which facilitates continuous inspection of large-length and large-volume decorative paper.

[0013] Optionally, a threaded groove is horizontally provided at the other end of the rotating rod, and an assembly screw cap is provided at the other end of the rotating rod, with the assembly screw cap threadedly assembled in the threaded groove of the rotating rod.

[0014] By adopting the above technical solution, in order to ensure the stability of the decorative paper roll inserted on the rotating rod, the assembly screw cap is threaded into the screw groove of the rotating rod to ensure that the assembly screw cap presses against the decorative paper roll and keeps the decorative paper roll stable when it is unwound.

[0015] Optionally, the supplementary lighting components include a slide bar frame and a lampshade. The slide bar frame is horizontally fixed on the top surface of the rear rotating plate of the testing table, and a hole frame is vertically installed on the slide bar frame. A lampshade is horizontally installed below the hole frame, and a lamp rod is installed inside the lampshade. A sliding hole block is horizontally fixed at the bottom end of the hole frame, and the sliding hole block is horizontally slidably assembled on the slide bar frame.

[0016] By adopting the above technical solution, in order to switch the light movement of the decorative paper on the testing table during use, the lampshade is pulled to cause the sliding block at the bottom of the hole frame to slide horizontally on the slide rod frame, thus switching the light movement of the decorative paper on the testing table laterally.

[0017] Optionally, a sliding rod is vertically fixed on the top surface of the lampshade, and the sliding rod slides vertically through the mounting bracket. An adjusting screw is threaded through the mounting bracket, and the bottom end of the adjusting screw is rotatably connected to the top surface of the lampshade.

[0018] By adopting the above technical solution, in order to facilitate the adjustment of the height of the lampshade illuminating the paper later, the adjusting screw on the hole frame is manually rotated to push the lampshade to slide vertically on the hole frame, and the height of the lampshade illuminating the paper is adjusted in the vertical direction.

[0019] Optionally, a pull frame is vertically fixed to one end face of the lampshade, and a clamp is horizontally provided at the bottom end of the pull frame, and the clamp is vertically slidably assembled at the bottom end of the pull frame.

[0020] By adopting the above technical solution, in order to facilitate the comparison of colors on the decorative paper by clamping the color card later, the color card is placed between the clamp and the pull frame, and the color card is kept stable by clamping and squeezing the clamp and the pull frame.

[0021] Optionally, multiple clamping springs are vertically arranged between the bottom ends of the clamp and the pull frame, and the two ends of the multiple clamping springs are respectively fixed to the clamp and the pull frame.

[0022] By adopting the above technical solution, when the clamp and pull frame hold the extruded color card, the deformation of the clamping spring is used to push the clamp and pull frame to keep the extruded color card stable.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, the decorative paper roll to be tested is inserted into the unwinding device on one side of the testing table. The decorative paper roll is unwound on the unwinding device and laid on the top surface of the testing table. The decorative paper passes through the pressure rollers on the front and rear sides of the testing table. The decorative paper is then wound onto the winding device on the other side of the testing table. During testing, the decorative paper, under the action of the deformation force of the downward pressure spring, drives the guide rod frame at the bottom of the rotating plate to slide vertically down the perforated plate, causing the pressure rollers to press against the decorative paper to maintain stability during testing. This avoids the problem of bending and warping that easily occurs when testing large areas of decorative paper, thus ensuring the stability of the decorative paper during testing. At the same time, in order to ensure continuous testing of long decorative paper, the unwinding device and winding device are used to wind the paper through the testing table, which facilitates continuous testing of large-length and large-volume decorative paper.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a color difference detection station for decorative paper. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A color difference detection table for decorative paper includes a detection table 1, an unwinding component 2, a rewinding component 3, and a lighting component 4. Perforated plates 11 are horizontally fixed on both the front and rear sides of the upper part of the detection table 1. A rotating plate 12 is horizontally arranged on the perforated plate 11. Multiple pressure rollers 121 are horizontally rotatably connected to the vertical end face of the rotating plate 12 near the detection table 1. A guide rod frame 13 is vertically fixed on the bottom surface of the rotating plate 12. The guide rod frame 13 is slidably inserted into the perforated plate 11. A downward pressure spring 14 is vertically fixed on the bottom surface of the guide rod frame 13, and the top end of the downward pressure spring 14 is fixed to the bottom surface of the perforated plate 11. Unwinding components 2 and rewinding components 3 are respectively arranged on the rear sides of both end faces of the detection table 1. A lighting component 4 is arranged on the top surface of the rotating plate 12 on the rear side of the detection table 1.

[0032] By adopting the above technical solution, the decorative paper roll to be tested is inserted into the unwinding component 2 on one side of the testing table 1. The decorative paper roll is unwound on the unwinding component 2 and laid on the top surface of the testing table 1. The decorative paper passes through the pressure rollers 121 on the front and rear sides of the testing table 1. The decorative paper is then wound onto the winding component 3 on the other side of the testing table 1. During testing, the decorative paper is driven by the deformation force of the downward pressure spring 14, which drives the guide rod frame 13 at the bottom of the rotating plate 12 to slide vertically down the perforated plate 11. This causes the pressure rollers 121 to press against the decorative paper to maintain stability during testing. This avoids the problem of bending and warping that easily occurs when testing large areas of decorative paper, thus ensuring the stability of the decorative paper during testing. At the same time, in order to ensure continuous testing of long decorative paper, the unwinding component 2 and the winding component 3 are used to wind the paper through the testing table 1, which facilitates continuous testing of large-length and large-volume decorative paper.

[0033] Reference Figure 3 and Figure 4 Both the unwinding component 2 and the rewinding component 3 include a rotating base 5. The rotating base 5 is fixed to the rear side of the side end face of the inspection table 1, and a rotating rod 6 is horizontally rotatably connected to the rotating base 5, with a decorative paper roll inserted into the rotating rod 6. During use, the rotating base 5 is fixed to the rear side of the side end face of the inspection table 1, and the rotating rod 6 rotatably connected to the rotating base 5 facilitates the rotation of the unwinding decorative paper roll. A motor 7 is horizontally fixed to the rotating base 5, and the output end of the motor 7 is fixed to the end of the rotating rod 6. Starting the motor 7 on the rotating base 5 drives the rotating rod 6 to rotate on the rotating base 5, thereby driving the unwinding component 2 and the rewinding component 3 to rewind the paper through the inspection table 1, facilitating continuous inspection of large-length and large-volume decorative paper. A screw groove 61 is horizontally opened at the other end of the rotating rod 6, and an assembly screw cap 62 is provided at the other end of the rotating rod 6, with the assembly screw cap 62 threadedly assembled into the screw groove 61 of the rotating rod 6. To ensure the stability of the decorative paper roll inserted on the rotating rod 6, the assembly screw cap 62 is threaded into the screw groove 61 of the rotating rod 6, ensuring that the assembly screw cap 62 presses against the decorative paper roll and keeps the decorative paper roll stable when unwinding.

[0034] Reference Figure 2 and Figure 5The supplementary lighting component 4 includes a slide bar frame 41 and a lampshade 45. The slide bar frame 41 is horizontally fixed to the top surface of the rear rotating plate 12 of the testing table 1, and a hole frame 42 is vertically installed on the slide bar frame 41. The lampshade 45 is horizontally installed below the hole frame 42, and a lamp rod is installed inside the lampshade 45. A sliding hole block 43 is horizontally fixed to the bottom end of the hole frame 42, and the sliding hole block 43 is horizontally slidably assembled on the slide bar frame 41. In use, in order to switch the light movement of the decorative paper on the testing table 1, the lampshade 45 is pulled to drive the sliding hole block 43 at the bottom end of the hole frame 42 to slide horizontally on the slide bar frame 41, thus switching the light movement of the decorative paper on the testing table 1 laterally. A slide bar 451 is vertically fixed to the top surface of the lampshade 45, and the slide bar 451 is vertically slidably assembled through the hole frame 42. An adjusting screw 44 is threaded through the hole frame 42, and the bottom end of the adjusting screw 44 is rotatably connected to the top surface of the lampshade 45. In order to facilitate the adjustment of the height of the lampshade 45 illuminating the paper during use, the adjusting screw 44 on the hole frame 42 is manually rotated to push the lampshade 45 to slide vertically on the hole frame 42, and the height of the lampshade 45 illuminating the paper is adjusted in the vertical direction.

[0035] Reference Figure 5 A pull frame 46 is vertically fixed to one end face of the lampshade 45, and a clamp 47 is horizontally arranged at the bottom end of the pull frame 46. The clamp 47 is vertically slidably assembled at the bottom end of the pull frame 46. Later, to facilitate comparison of colors on decorative paper using color cards, the color card is placed between the clamp 47 and the pull frame 46, and the clamp 47 and pull frame 46 hold and compress the color card to maintain stability. Multiple clamping springs 48 are vertically arranged between the bottom ends of the clamp 47 and the pull frame 46, and the two ends of the clamping springs 48 are respectively fixed to the clamp 47 and the pull frame 46. When the clamp 47 and the pull frame 46 clamp and compress the color card, the deformation of the clamping springs 48 pushes the clamp 47 and the pull frame 46 to hold and compress the color card to maintain stability.

[0036] The implementation principle of a color difference detection table for decorative paper in this application embodiment is as follows: During use, the roll of decorative paper to be tested is inserted into the unwinding member 2 on one side of the detection table 1. The motor 7 on the rotating base 5 is started, which drives the rotating rod 6 to rotate on the rotating base 5, thereby driving the unwinding member 2 and the winding member 3 to wind the paper through the detection table 1, which is convenient for continuous testing of large-length and large-volume decorative paper. The decorative paper roll is unwound on the unwinding member 2 and laid on the top surface of the detection table 1. The decorative paper passes through the pressure rollers 121 on the front and rear sides of the detection table 1. The decorative paper is then wound onto the winding member 3 on the other side of the detection table 1. During testing, the decorative paper is driven by the deformation force of the downward pressure spring 14 to drive the guide rod frame 13 at the bottom of the rotating plate 12 to be vertically mounted on the perforated plate 11. The paper slides down, causing the pressure roller 121 to press against the decorative paper to maintain stability during testing. To facilitate color card comparison on the decorative paper, the color card is placed between the clamp 47 and the pull frame 46. The clamp 47 and the pull frame 46 hold and compress the color card to maintain stability. To switch the light movement of the decorative paper on the testing table 1, the lampshade 45 is pulled, causing the sliding hole block 43 at the bottom of the hole frame 42 to slide horizontally on the slide bar frame 41, thus switching the light movement of the decorative paper on the testing table 1 laterally. To facilitate the adjustment of the height of the lampshade 45 illuminating the paper later, the adjusting screw 44 on the hole frame 42 is manually rotated to push the lampshade 45 to slide vertically on the hole frame 42, thus adjusting the height of the lampshade 45 illuminating the paper vertically.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
