[0071] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0072] Figure 1 A schematic structural diagram of a color measurement device according to an embodiment of the present disclosure is shown; Figure 2 for Figure 1 Schematic diagram of the structure of the front end of the middle shell; Figure 3 It is a structural diagram of the measurement component; it can be understood that Figure 1 FIG. 4 shows a partial structure of the color measurement device located at the rear end of the housing in this embodiment. Figure 2 The figure shows the structure of the color measurement device in this embodiment at the front end of the housing. Before the measurement begins, the sample to be tested is located at the front end of the housing. Figure 3 The diagram shows a partial structure of the measuring components in the color measurement device in this embodiment.

[0073] The present disclosure provides a color measurement device, such as Figures 1 to 3As shown, the color measurement device includes: a measuring component 10, a mounting member 20 and a moving component 30. The measuring component 10 includes a housing 11 and a detection portion 12 at least partially disposed in the housing 11. The housing 11 has an inlet 13 and an outlet 14 disposed relatively to each other along a first direction. The mounting member 20 is used to sleeve a sample to be tested 21. The moving component 30 is connected to the mounting member 20. The moving component 30 is used to drive the sample to be tested 21 to move relative to the housing 11 along the first direction, so that the sample to be tested 21 enters the housing 11 from the inlet 13 and can pass through the housing 11 from the outlet 14, thereby changing the portion of the sample to be tested 21 located at a preset position in the housing 11. The detection portion 12 is used to measure the colorimetric data of the portion of the sample to be tested 21 located at the preset position.

[0074] According to the embodiments of the present disclosure, it should be noted that:

[0075] During the fiber production stage, it is necessary to test the dyeing condition of the fiber. For example, when testing the fiber in multiple spindles of the same batch (multiple spindles of the same batch), the multiple spindles of the same batch can be used to weave a silk fabric and dye it to obtain a test sample 21 (such as a garter).

[0076] The test sample 21 can be a sleeve-like structure woven from fiber yarns (similar to stockings), which can be divided into multiple test sections along the length direction. Each test section can use fiber yarns from a silk spindle, so that the entire test sample 21 can be sampled from multiple spindles of fiber yarns of the same batch number. The color measuring device can automatically measure the chromaticity data of each test section of the entire test sample 21, thereby realizing the detection of multiple spindles of fiber yarns of the same batch number.

[0077] The color measurement device includes a measuring assembly 10, a mounting member 20, and a moving assembly 30. The mounting member 20 can be a plate-like structure that can extend along a first direction (its length). A test sample 21 can be placed on the mounting member 20 (the length of the test sample 21 can coincide with the first direction), thereby stretching the test sample 21 to make its surface smooth.

[0078] It can be understood that the sample to be tested 21 is usually longer, and its length is greater than the length of the mounting member 20. When it is mounted, the portion of the sample to be tested 21 close to the measuring component 10 can be flatly attached to the mounting member 20, while the portion of the sample to be tested 21 away from the measuring component 10 can be stacked on the mounting member 20, so that some sections to be tested that are measured first remain flat, and some sections to be tested that are measured later can be temporarily stacked, thereby reducing the volume of the color measuring device.

[0079] The measuring assembly 10 includes a housing 11 and a detection unit 12 located therein. The detection unit 12 can be a measuring component capable of performing colorimetric measurements, such as a colorimeter. The detection unit 12 can detect colorimetric data, such as color values, of a portion of a test sample 21 (a test segment) at a predetermined location.

[0080] The housing 11 can be made of a common opaque material such as metal or alloy, which can prevent external light beams from passing through the housing 11 and entering the interior of the housing 11, thereby forming a dark measurement environment within the housing 11, thereby preventing external light beams from affecting the measurement results of the test sample 21. The detection unit 12 can be disposed at any position within the housing 11, facing the interior of the housing 11. For example, the detection unit 12 can be disposed at the top of the interior of the housing 11.

[0081] The housing 11 includes an inlet 13 and an outlet 14 along a first direction, and the first direction may be a horizontal direction, such as Figure 1 In the direction of the arrow, the positions of the inlet 13 and the outlet 14 correspond to each other and can connect the interior space of the housing 11 with the outside. For ease of explanation, the end of the inlet 13 of the housing 11 that is away from the outlet 14 is referred to as the front end of the inlet 13 or the front end of the housing 11 (specifically, the front of the exterior of the housing 11), and the end of the outlet 14 that is away from the inlet 13 is referred to as the rear end of the outlet 14 or the rear end of the housing 11 (specifically, the rear end of the exterior of the housing 11).

[0082] The sample to be tested 21 can enter the interior of the shell 11 from the entrance 13, and can have a preset position inside the shell 11. The preset position can be understood as the position in the shell 11 that the detection part 12 can measure. For example, the position directly opposite the detection part 12 can be the preset position, and the detection part 12 can measure the color of the part of the sample to be tested 21 located at the preset position. It can be understood that the part of the sample to be tested 21 located at the preset position can be the current section to be tested that is currently being measured among multiple sections to be tested.

[0083] After obtaining the color data of the current section to be tested, the measured color data can be compared with preset standard color data (e.g., standard color values) to obtain a measurement result, thereby determining the color grade of the portion of the test sample 21. If the color grade meets the requirements, the batch of fiber yarns (or silk spindles) corresponding to the portion of the test sample 21 (the current section to be tested) meets the requirements and can proceed to subsequent processes. If the color grade does not meet the requirements, the batch of fiber yarns (or silk spindles) corresponding to the portion of the test sample 21 will be downgraded or discarded.

[0084] In addition, after the chromaticity data of the current segment to be tested is detected, the current segment to be tested can be moved away from the preset position by moving the component 30, and the next segment to be tested can be moved to the preset position to continue measurement, thereby realizing the measurement of the entire sample to be tested 21. The segment to be tested after the measurement is completed can also leave the interior of the shell 11 through the outlet 14.

[0085] The detection part 12 that is at least partially arranged in the shell 11 can be understood as the detection part 12 for measuring the color of the test sample 21 can be located entirely in the shell 11, or the detection part 12 can include multiple components, some of which can be arranged inside the shell 11, and other components can be located outside the shell 11.

[0086] In one embodiment, the test sample 21 can be a dyed garter, which can be made of filament yarn and thus be elastic. Since the test sample 21 is soft and easily overlapped and wrinkled, directly feeding the overlapped and wrinkled test sample 21 into the measurement assembly 10 for color measurement will result in inaccurate measurement results. Therefore, a mounting member 20 is required to fix the test sample 21. The mounting member 20 can enter the test sample 21 through the opening of the test sample 21 and use the elasticity of the test sample 21 to stretch the test sample 21 so that the test sample 21 can be placed on the mounting member 20. The length of the mounting member 20 can be greater than the length of the housing 11, so that one end of the mounting member 20 can be located outside the inlet 13 and the other end can extend out of the outlet 14, allowing the mounting member 20 to pass through the housing 11, thereby allowing the portion of the garter located inside the housing 11 to remain flat, that is, to be attached to the surface of the mounting member 20, while the portion of the garter located outside the housing 11 can be in a stacked state.

[0087] It can be understood that the moving component 30 can be set at any position of the mounting member 20, for example, the moving component 30 can be located at the front end of the shell 11, or at the rear end of the shell 11, or partially at the front end of the shell 11 and the other partially at the rear end of the shell 11.

[0088] The moving assembly 30 may include a motor, which drives the test sample 21 to move relative to the housing 11 along the first direction. The moving assembly 30 may also include a motor and a transmission assembly connected to the motor, such as a gear rack, a connecting rod mechanism, etc. The transmission assembly is connected to the mounting member 20, and the motor drives the transmission assembly, which drives the test sample 21 to move relative to the housing 11 along the first direction. The moving assembly 30 connected to the mounting member 20 can drive the test sample 21 to enter the interior of the housing 11 from the entrance 13 and move along the first direction. When the test segment in the test sample 21 moves to the preset position corresponding to the detection unit 12, the detection unit 12 can measure the color of the portion of the test sample 21 (the current test segment) located at the preset position. The moving assembly 30 can drive the portion of the test sample 21 to move toward the exit 14 after the measurement is completed, and at the same time move the next test segment of the current test segment to the preset position. The detection unit 12 can measure the color of the new current test segment located at the preset position, thereby achieving measurement of multiple test segments in the test sample 21. In one embodiment, when the sample to be tested 21 moves to the preset position corresponding to the detection part 12, the moving component 30 can stop driving the sample to be tested 21 to move, and the detection part 12 can measure the color of the part of the sample to be tested 21 (the current sample to be tested) located at the preset position. After the measurement is completed, the moving component 30 can drive the part of the sample to be tested 21 after the measurement is completed to continue to move along the first direction, move the next section to be tested to the preset position, and continue measuring.

[0089] In other embodiments, the moving assembly 30 can drive the test sample 21 to move linearly along the first direction at a constant speed, and the length of each detection segment can be kept consistent. Each detection segment of the test sample 21 can sequentially pass through a preset position. By calculating the interval between the centers of two adjacent detection segments passing through the preset position, the interval measurement time of the detection unit 12 can be adjusted, so that the detection unit 12 can perform a measurement after the interval measurement time, thereby measuring the color of the center positions of multiple detection segments.

[0090] In one embodiment, there may be multiple detection units 12 , and the multiple detection units 12 can simultaneously measure the color of a portion of the test sample 21 at the corresponding preset positions, which can further improve the efficiency of color measurement.

[0091] It can be understood that in the related art, it is time-consuming and labor-intensive to manually detect the color of each section to be tested, which is inefficient, and the color measurement results vary from person to person, and the accuracy of the measurement cannot be guaranteed. According to the embodiment of the present disclosure, first, the sample to be tested 21 can be fixed by placing it on the mounting member 20 to avoid inaccurate measurement results due to the presence of stacking or wrinkles in the sample to be tested 21. Secondly, the sample to be tested 21 can be driven to move into the measuring component 10 by the moving component 30, and the color data of the current section to be tested at the preset position can be automatically measured by the detection unit 12 in the measuring component 10. As the sample to be tested 21 moves, each section to be tested can be located in the preset position of the shell in turn, thereby realizing automatic measurement of the color data of multiple sections to be tested of the sample to be tested 21, saving time and effort, and improving the efficiency and accuracy of color measurement of the sample to be tested 21.

[0092] In some embodiments, as Figures 1 to 2 As shown, the moving assembly 30 includes a first driving portion, a connecting portion, and a second driving portion; the first driving portion is located at the front end of the inlet 13 away from the outlet 14, and is used to drive the mounting member 20 to move in a first direction, so that the mounting member 20 moves from outside the shell 11 to the point where it passes through the shell 11, thereby allowing the test sample 21 to pass through the shell 11. The connecting portion is located at the rear end of the outlet 14 away from the inlet 13, and is used to connect to the end of the test sample 21 that passes through the shell 11. The second driving portion is located at the rear end of the outlet 14, and is used to drive the connecting portion to move, so as to drive the test sample 21 to move relative to the mounting member 20 in the first direction, thereby changing the portion of the test sample 21 located at a preset position within the shell 11.

[0093] It can be understood that the first driving part is located in front of the shell 11 and can be a driving structure such as a motor, so that the mounting part 20 can be driven to enter the interior of the shell 11 from the entrance 13 of the shell 11 along the first direction and pass through the outlet 14, so that the mounting part 20 can pass through the shell 11, and then the sample to be tested 21 can also pass through the shell 11. After the mounting part 20 passes through the shell 11, the sample to be tested 21 on the mounting part 20 can be connected to the connecting part located at the rear end of the outlet 14. The connection can be done manually, or the connection can be achieved by making the sample to be tested 21 contact the connecting part through the adhesive structure on the connecting part.

[0094] The second driving part can also be a driving structure such as a motor, which can be located at the rear of the shell 11, and can drive the connecting part to move. Since the connecting part is connected to the sample to be tested 21, the connecting part can drive the sample to be tested 21 to move relative to the mounting part 20, that is, after the mounting part 20 is passed through the shell 11, the position of the mounting part 20 remains stationary, and the connecting part drives the sample to be tested 21 to move relative to the mounting part 20 along the first direction (along the direction from the front end to the rear end of the shell 11), thereby driving the sample to be tested 21 to leave the preset position after the measurement is completed, and the next section to be tested can be moved to the preset position for measurement. The detection part 12 can measure the color data of the section to be tested passing through the preset position during the above movement.

[0095] In this embodiment, the garter can be manually put on the mounting member 20, and then the first driving unit drives the mounting member 20 and the test sample 21 on the mounting member 20 to pass through the housing 11, so that the test sample 21 can be connected to the connecting portion. Then, the mounting member 20 is kept stationary, and then the second driving unit can drive the test sample 21 to move relative to the mounting member 20 through the connecting portion, thereby changing the test section located at the preset position. The detection unit 12 can detect each test section passing through the preset position.

[0096] It can be understood that since part of the samples to be tested 21 are stacked on the mounting member 20, the movement of the connecting portion can pull the samples to be tested 21 to move relative to the mounting member 20, so that the stacked samples to be tested can also move smoothly to the preset position under the action of the pulling force, thereby realizing the detection of the entire sample to be tested.

[0097] According to the embodiment of the present disclosure, the second driving part and the connecting part can make multiple sections to be tested pass through the preset position in sequence, thereby realizing automatic detection of multiple sections to be tested and improving the efficiency of color measurement of the test sample 21.

[0098] In some embodiments, as Figure 1 As shown, the connecting portion may include a winding wheel 31 , and the second driving portion is used to drive the winding wheel 31 to rotate so that the test sample 21 is wound around the winding wheel 31 , thereby moving the test sample 21 relative to the mounting member 20 along the first direction.

[0099] It can be understood that the first driving unit can drive the sample to be tested 21 to pass through the shell 11 and connect with the winding wheel 31 located at the rear end of the outlet 14. For example, the winding wheel 31 can be provided with Velcro. When the sample to be tested 21 moves to pass through the shell 11, it can contact the Velcro on the winding wheel 31, thereby realizing the connection between the two. The second driving unit can drive the winding wheel 31 to rotate, so that the sample to be tested 21 that has been tested can be wound on the winding wheel 31, which is conducive to the collection of the sample to be tested 21.

[0100] According to the embodiment of the present disclosure, the test sample 21 can be moved relative to the mounting member 20, and the test sample 21 after measurement can be wound on the winding wheel 31 to collect the test sample 21 after measurement, and the measurement efficiency of the test sample 21 can be improved.

[0101] In some embodiments, the second driving unit includes a first motor located at the rear end of the housing 11 , and the winding wheel 31 is fixedly connected to the output shaft of the first motor.

[0102] It can be understood that the first motor can be a device in the related art that can drive other devices to rotate. For example, the first motor can be a servo motor, a torque motor, etc.

[0103] The first motor and the winding wheel 31 can always be located at the rear of the housing 11, and the output shaft of the first motor can be connected to the rotating shaft of the winding wheel 31, thereby driving the winding wheel 31 to rotate, and the test sample 21 can be wound on the winding wheel 31. At the same time, the test sample 21 moves relative to the mounting member 20 along the first direction, which can change the portion of the test sample 21 (the section to be tested) located at a preset position in the housing 11, and the detection unit 12 can perform color measurement on each section to be tested. According to an embodiment of the present disclosure, the winding wheel 31 can be driven to rotate by the first motor to collect the test sample 21 after the measurement is completed, and the measurement efficiency of the test sample 21 can be improved.

[0104] In some embodiments, Figure 4 FIG. 1 is a schematic structural diagram of a color measurement device according to another embodiment of the present disclosure; FIG. Figure 4 As shown, the moving assembly 30 further includes: a bracket 32 and a first slide rail 33 located at the rear end of the housing 11. The bracket 32 extends in a first direction, and one end of the bracket 32 in the first direction is rotatably connected to the winding wheel 31, and the other end of the bracket 32 in the first direction is slidably mounted on the first slide rail 33. The second driving portion is further configured to synchronously drive the bracket 32 to slide on the first slide rail 33 when the mounting member 20 moves from outside the housing 11 to penetrate the housing 11, so that the winding wheel 31 can move from the front end of the housing 11 to the rear end of the housing 11 via the inlet 13 and the outlet 14. The second driving portion is further configured to drive the winding wheel 31 to rotate when the winding wheel 31 moves to the rear end of the housing 11.

[0105] It can be understood that the first direction can be Figure 4 The left and right directions, Figure 4The left side of the shell 11 is the front end of the shell, and the right side of the shell 11 is the rear end of the shell. The bracket 32 can extend along the first direction, and its length is sufficient to allow it to pass through the shell 11. The front end of the bracket 32 along the first direction can be rotatably connected to the winding wheel 31, and the rear end of the bracket 32 along the first direction can extend in the vertical direction and can be slid on the first slide rail 33. The sliding method can adopt a method in which the slider and the slide rail cooperate. The second driving unit can also drive the bracket 32 to slide on the first slide rail 33, so that the bracket 32 can pass through the shell 11 through the entrance 13 and the exit 14, or the bracket 32 can be located at the rear of the shell 11. Figure 4 The figure shows the state where the winding wheel 31 is located at the front end of the shell 11 . At this time, the mounting member 20 is located at the front end of the shell 11 . When the winding wheel 31 moves to the rear end of the shell 11 , the mounting member 20 passes through the shell 11 .

[0106] During the measurement process, the bracket 32 can first be installed through the shell 11 so that the winding wheel 31 can be located in front of the entrance 13 of the shell 11, the mounting member 20 can also be located in front of the shell 11, and the test sample 21 can be placed on the mounting member 20. At this time, the test sample 21 is completely located outside the shell 11, and its rear end facing the shell 11 can be connected to the winding wheel 31 in front of the entrance 13.

[0107] Then, the first drive unit can drive the mounting member 20 to move backward, and at the same time, the second drive unit can drive the bracket 32 to move backward along the first slide rail 33. The mounting member 20 and the winding wheel 31 remain synchronized, that is, at this time, the mounting member 20 and the winding wheel 31 remain relatively stationary. When the mounting member 20 moves to penetrate the housing 11, the winding wheel 31 also moves from the front of the housing 11 to the rear of the housing 11 through the inlet 13 and the outlet 14.

[0108] Then, the first driving part stops and the mounting member 20 remains stationary. The second driving part can also be connected to the rotating shaft of the winding wheel 31 through the transmission mechanism and drive the winding wheel 31 to rotate, thereby realizing the movement of the test sample 21 relative to the mounting member 20.

[0109] According to the embodiment of the present disclosure, when the test sample 21 is mounted, the test sample 21 can be manually connected to the winding wheel 31 at the same time, so that no manual participation is required in the entire subsequent measurement process, saving time and effort. The winding wheel 31 and the test sample 21 are synchronously moved to the rear end of the shell 11, and the winding wheel 31 is driven to rotate by the second driving unit to realize the movement of the test sample 21 relative to the mounting part 20, thereby improving the efficiency of color measurement of the test sample 21.

[0110] In some embodiments, as Figure 4As shown, the second drive unit includes a first drive motor and a second drive motor. The first drive motor is used to drive the bracket 32 to slide on the first slide rail 33. The moving assembly 30 also includes a clamping member. The clamping member and the second drive motor are both located at the rear end of the housing 11. The clamping member is used to clamp the winding wheel 31 after the winding wheel 31 moves to the rear end of the housing 11. The second drive motor is used to drive the winding wheel 31 to rotate through the clamping member.

[0111] It is understood that the clamping member can be a clamping claw structure or a block structure, which can be located behind the housing 11 and connected to the second drive motor. For example, the clamping member can be connected or disconnected from the rotating shaft of the winding wheel 31 through a clamping claw structure or a block structure.

[0112] The first drive motor and the second drive motor may both have a common drive motor structure in the related art.

[0113] The first drive motor can drive the bracket 32 to slide on the first slide rail 33, so that the winding wheel 31 and the sample to be tested 21 can be moved out of the shell 11 synchronously. When the winding wheel 31 moves to the rear end of the shell 11, the clamping member can clamp the winding wheel 31 so that the rotating shaft of the winding wheel 31 is fixedly connected to the clamping member. Since the clamping member is connected to the second drive motor, the second drive motor drives the clamping member to rotate to realize the rotation of the winding wheel 31, thereby realizing the movement of the winding wheel 31 along the first direction following the bracket 32, and realizing the rotation of the winding wheel 31 when the winding wheel 31 moves to the rear of the shell 11, and winding the sample to be tested 21 on the winding wheel 31. The structure is simple and easy to implement.

[0114] In some embodiments, the moving assembly 30 further includes a slide extending along the first direction, the slide being located at the rear end of the outlet 14; the connecting portion further includes a sliding member, and the second driving portion is used to drive the sliding member to slide along the slide so that the sample to be tested 21 moves relative to the mounting member 20 along the first direction.

[0115] It can be understood that in this embodiment, the connecting portion may be block-shaped, and the connecting portion may provide a pulling force to the test sample 21 by moving along the first direction, thereby driving the test sample 21 to move relative to the mounting member 20 .

[0116] The slideway can be located at the rear of the housing 11 , and the connecting portion includes a first sliding member that can be slidably arranged on the slideway along a first direction, thereby realizing movement of the connecting portion along the first direction, and the structure is simple and easy to realize.

[0117] In some embodiments, a first Velcro is provided on the surface of the connection portion, and the first Velcro is used to adhere to the test sample 21 when the test sample 21 passes through the housing 11 .

[0118] It can be understood that in the above embodiment, the first Velcro can be provided on the surface of the connecting portion for connecting with the sample to be tested 21. For example, when the connecting portion is a winding wheel 31, the first Velcro can be provided on the circumferential surface. For another example, when the connecting portion is a block structure, the first Velcro can be provided on the upper surface or lower surface of the block structure in the vertical direction. When the sample to be tested 21 passes through the shell 11, the sample to be tested 21 can be automatically or manually bonded to the connecting portion, so that the connecting portion can drive the sample to be tested 21 to move relative to the mounting member 20 in the first direction, and the sample to be tested 21 can be separated from the mounting member 20 after the measurement is completed. According to the embodiment of the present disclosure, it is possible to bond to the sample to be tested 21 through the first Velcro, and the Velcro has a simple structure and low cost.

[0119] On the basis of the above embodiment, a clamping portion is further provided outside the connecting portion, and the clamping portion is used to press the sample to be tested 21 against the connecting portion.

[0120] It can be understood that the clamping portion can be a structure extending in the horizontal direction, and its extension direction is perpendicular to the first direction. The clamping portion and the connecting portion can be connected by an elastic component, and the elastic force of the elastic component can press the clamping portion against the connecting portion.

[0121] When the connecting portion is connected to the sample to be tested 21, the clamping portion can press the sample to be tested 21 against the connecting portion, thereby improving the connection reliability between the connecting portion and the sample to be tested 21, and then providing a relatively stable pulling force to the sample to be tested 21, keeping the stretching degree of each section to be tested roughly the same, which is conducive to the accuracy of the test results.

[0122] Based on the above embodiments, Figure 2 As shown, the moving assembly 30 also includes a second slide rail 34 located at the front end of the entrance 13, and one end of the mounting member 20 has a second sliding member 35 slidably arranged on the second slide rail 34. The first driving part is used to drive the mounting member 20 to slide relative to the second slide rail 34 along the first direction.

[0123] It is understood that in this embodiment, the movement of the mounting member 20 relative to the housing 11 can be achieved by the second slide rail 34 and the second sliding member 35. The second slide rail 34 and the second sliding member 35 can rely on a slider slide or a screw nut to achieve movement along the first direction.

[0124] The length of the second slide rail 34 can be selected according to the length of the housing 11 to ensure that the test sample 21 can be moved from outside the housing 11 to pass through the housing 11. The test sample 21 can be placed on the mounting member 20, and the first driving unit can drive the second sliding member 35 to slide relative to the second slide rail 34 in the first direction, thereby driving the test sample 21 to move from outside the housing 11 to pass through the housing 11. The structure is simple and easy to implement.

[0125] In some embodiments, the color measurement device further includes: a tension detection sensor, which is disposed at the connecting portion to detect the tension between the test sample 21 and the connecting portion.

[0126] It can be understood that the test sample 21 usually has elastic force. Since it will move relative to the mounting member 20 under the tension of the connecting part, the length of the test section will change with the magnitude of the tension. In order to improve the accuracy of the measurement results, it is usually necessary to keep the tension relatively constant.

[0127] The tension sensor can be a device that can realize tension detection in the relevant technology. The tension detection sensor can detect the tension value between the test sample 21 and the connecting part. If the tension value between the test sample 21 and the connecting part is not within the set threshold and / or the tension value changes, the deformation of the test sample 21 will be outside the preset range, so that the color data of the test sample 21 changes, resulting in inaccurate color measurement of the test sample 21. Therefore, the output power of the second driving part can be adjusted by feedback adjustment according to the tension value measured by the tension detection sensor until the tension between the test sample 21 and the connecting part is within the set threshold or remains unchanged.

[0128] According to the embodiment of the present disclosure, it is possible to ensure that the tension between the test sample 21 and the connecting portion is within a set threshold or the tension value does not change, thereby controlling the stretching degree of the test sample 21 and improving the accuracy of the color measurement of the test sample 21.

[0129] In some embodiments, Figure 5 FIG. 2 shows a schematic structural diagram of a color measurement device according to another embodiment of the present disclosure; FIG. Figure 5 As shown, the moving assembly 30 includes a third drive unit and a transmission belt 36 connected to the third drive unit. The third drive unit and transmission belt 36 are located at the front end of the inlet 13. A second Velcro strip is provided on the surface of the transmission belt 36 and is arranged around the transmission belt 36. The second Velcro strip is used to removably adhere to the portion of the test sample 21 that is mounted on the outside of the mounting member 20. The third drive unit is used to drive the transmission belt 36, thereby causing the test sample 21 and the mounting member 20 to move synchronously with the transmission belt 36 in the first direction, thereby changing the portion of the test sample 21 located at a predetermined position within the housing 11.

[0130] In this embodiment, during the measurement process, the mounting member 20 and the test sample 21 remain relatively stationary, and the moving assembly 30 can drive the mounting member 12 and the test sample 21 to move relative to the housing 11, thereby changing the test section located at the preset position.

[0131] The transmission belt 36 can be a common structure capable of realizing belt transmission, and its surface can be provided with a second Velcro capable of adhering to the front test sample 21. The transmission belt 36 can be located at the front end of the housing 11.

[0132] It is understood that the test sample 21 can be mounted on the mounting member 20, and the viscosity of the second Velcro can be used to fix the test sample 21 to the transmission belt 36, thereby achieving a connection between the mounting member 20 and the transmission belt 36. The third driving unit can drive the transmission belt 36 to move, and the transmission belt 36 can drive the test sample 21 to move into the housing 11. Due to the limited adhesive force of the second Velcro, when the mounting member 20 approaches the entrance 13 and the transmission belt 36 needs to move in an arc direction, the test sample 21 can overcome the adhesive force and separate from the transmission belt 36. The separated portion of the test sample 21 can follow the mounting member 20 from the entrance 13 into the housing 11, and as the transmission belt 36 continues to move, the mounting member 20 can move in the first direction relative to the housing 11. The detection unit 12 can detect the test section passing through the preset position.

[0133] The number of the second magic tape can be multiple, for example, each can extend along the extension direction of the transmission belt 36, and multiple second magic tapes are arranged at intervals along the width direction of the transmission belt 36. Of course, the second magic tape can also cover the entire surface of the transmission belt 36.

[0134] In addition, in this embodiment, the mounting member 20 can be configured to be longer, so that it can measure more sections to be tested while passing through the housing 11. In addition, after the mounting member 20 is separated from the entire transmission belt 36, the mounting member 20 can be manually removed and removed from the housing 11, and another section of the test sample 21 or another test sample 21 can be re-installed to continue the measurement.

[0135] According to the embodiment of the present disclosure, the transmission belt 36 can drive the test sample 21 to move into the shell 11 and pass through the shell 11, and the part of the test sample 21 located at the preset position in the shell 11 can be changed. The detection unit 12 can measure the color of different sections of the test sample 21, thereby improving the efficiency of the color measurement of the test sample 21.

[0136] It can be understood that since the test sample 21 is bonded to the second Velcro on the surface of the transmission belt 36 , the stretching length of each test section can be manually controlled during bonding, thereby improving the accuracy of the measurement.

[0137] In some embodiments, Figure 6 A schematic structural diagram of a cutting member and a separating member according to another embodiment of the present disclosure is shown. Figure 6As shown, the moving assembly 30 also includes: a cutting member 37 and a separating member 38; the cutting member 37 and the separating member 38 are located at the rear end of the outlet 14, the cutting member 37 is used to cut the test sample 21 passing through the outlet 14 along the first direction, and the separating member 38 is used to drive the cut test sample 21 to move so that the cut test sample 21 is separated from the mounting member 20.

[0138] It can be understood that the first direction is Figure 6 The direction perpendicular to the paper surface. The cutting piece 37 can be a blade made of a material such as metal or alloy. The cutting piece 37 can divide the sample to be tested 21 passing through the outlet 14 of the housing 11 into one or more parts. The number of separating pieces 38 can be selected according to the number of the samples to be tested 21 after cutting. The separating pieces 38 can correspond to the samples to be tested 21 after cutting one by one. Each separating piece 38 can drive the corresponding divided sample to be tested 21 to move, so that the samples to be tested 21 can be separated from the mounting piece 20 after cutting. According to the embodiment of the present disclosure, the sample to be tested 21 can be divided into one or more parts by the cutting piece 37, and the sample to be tested 21 can be more easily detached from the mounting piece 20, thereby avoiding the difficulty in detaching the sample to be tested 21 from the mounting piece 20 due to the long length of the sample to be tested 21.

[0139] In some embodiments, as Figure 6 As shown, the cutting member 37 includes a first cutting portion 371 and a second cutting portion 372, which are spaced apart along the second direction. The first cutting portion 371 and the second cutting portion 372 are respectively used to cut the test sample 21 into two sub-portions from both sides of the test sample 21. The separating member 38 includes a fourth driving portion, a first wheel body 381 and a second wheel body 382, which are spaced apart along the third direction. The mounting member 20 can move relative to the housing 11 along the first direction between the first wheel body 381 and the second wheel body 382. The fourth driving portion is used to drive the first wheel body 381 and the second wheel body 382 to rotate so that the first wheel body 381 is wound around one of the two sub-portions and the second wheel body 382 is wound around the other of the two sub-portions. The first direction, the second direction, and the third direction are arranged perpendicular to each other.

[0140] It can be understood that the second direction is Figure 6 The left and right directions, the third direction is Figure 6 In the vertical direction, the first cutting portion 371 and the second cutting portion 372 can be spaced apart along the second direction (horizontal direction perpendicular to the first direction), so that the sample to be tested 21 can be divided from both sides into two parts, the first wheel body 381 and the second wheel body 382 can be respectively arranged above and below the sample to be tested 21, that is, spaced apart along the vertical (third) direction. The first wheel body 381 and the second wheel body 382 can be respectively spaced apart. Figure 6 The dotted line in the figure is the axis for rotation. The first wheel body 381 can also automatically connect and wrap around the test sample 21 on the upper part of the mounting member 20 through Velcro or the like. Similarly, the second wheel body 382 can wrap around the test sample 21 on the lower part of the mounting member 20, making it easier to remove the mounting member 20 from the test sample 21.

[0141] This embodiment can adjust the rotational speed of the first wheel body 381 and the second wheel body 382 to keep it corresponding to the moving speed of the mounting member 20, thereby avoiding excessive tension on the test sample 21 and maintaining the stretching degree of the test sample 21 as much as possible, which is conducive to the accuracy of the results.

[0142] In some embodiments, the housing 11 is further provided with a roller rotatably connected to the housing 11 . The roller is located at one end of the housing 11 facing the first driving portion, and the wheel surface of the roller is used to press the sample to be tested 21 against the mounting member 20 .

[0143] It is understood that the width of the roller can be selected according to the width of the test sample 21 to ensure that the roller can cover the test sample 21 in the second direction. When the test sample 21 enters the housing 11, the roller can be set at the upper end of the entrance 13 of the housing 11. The upper surface of the test sample 21 can pass through the wheel surface of the roller. The roller can rotate and flatten the test sample 21 on the mounting member 20 to prevent wrinkles, so that the test sample 21 can enter the interior of the housing 11 smoothly. This can effectively prevent the wrinkles on the test sample 21 from affecting the color measurement results of the test sample 21, and can improve the accuracy of the color measurement of the test sample 21.

[0144] In some embodiments, the mounting member 20 is a mounting plate having a uniform color.

[0145] It is understood that the specific color of the chromatically uniform mounting plate can be any color, for example, the mounting plate can be a white mounting plate with uniform chromatically uniform color, a black mounting plate with uniform chromatically uniform color, etc. Placing the test sample 21 on the chromatically uniform mounting plate for color measurement can avoid the situation where the color data of each section to be tested is inconsistent due to the uneven chromatically uniform mounting plate, which in turn leads to inaccurate grading, thereby improving the accuracy of the color measurement of the test sample 21.

[0146] In some embodiments, as Figure 1 and 2 As shown, the shell 11 is also provided with an inlet baffle 131 and an outlet baffle 141. The inlet baffle 131 is rotatably connected to the inlet 13 to cover the gap between the inlet 13 and the mounting member 20 when the mounting member 20 passes through the inlet 13; the outlet baffle 141 is rotatably connected to the outlet 14 to cover the gap between the outlet 14 and the mounting member 20 when the mounting member 20 passes through the outlet 14.

[0147] It is understood that the widths of the inlet baffle 131 and the outlet baffle 141 are selected based on the widths of the inlet 13 and the outlet 14, respectively, to ensure that the inlet baffle 131 and the outlet baffle 141 can cover the gaps between the inlet 13 and the outlet 14, respectively, and the mounting member 20. The inlet baffle 131 and the outlet baffle 141 can be made of common opaque materials such as metals and alloys to prevent external light beams from passing through the inlet baffle 131 and the outlet baffle 141 and entering the interior of the housing 11.

[0148] It will be appreciated that after the mounting member 20 is inserted into the entrance 13, the entrance baffle 131 connected to the entrance 13 can be rotated to the gap between the entrance 13 and the mounting member 20, thereby covering the gap. After the mounting member 20 is inserted into the exit 14, the exit baffle 141 connected to the exit 14 can be rotated to the gap between the exit 14 and the mounting member 20, thereby covering the gap. According to the embodiments of the present disclosure, inaccurate color measurements of the test sample 21 due to external light beams entering the interior of the housing 11 due to gaps between the mounting member 20 and the entrance 13 and exit 14 can be avoided, thereby improving the accuracy of the color measurement of the test sample 21.

[0149] In some embodiments, as Figure 5 As shown, a line scan camera 40 is provided in the housing 11 , and the line scan camera 40 is used to detect movement data of the test sample 21 relative to the mounting plate.

[0150] It can be understood that a partition can be formed between each two adjacent segments to be tested by using fibers of different colors or different weaving methods. The shape of the partition is different from the segments to be tested and can be identified by image recognition.

[0151] The line scan camera 40 can be positioned anywhere within the housing 11, for example, toward the entrance. The line scan camera 40 can scan the movement data of the test sample 21 passing through a certain position. The movement data can include the image at that position and the time of capture. The movement data can be used to determine the time when the partition passed through that position. Combined with the distance between that position and the preset position, the movement speed of the test sample 21, and the length of the test section, the time when the middle position of the current test section reached the preset position can be predicted. This allows the color data of the detection unit 12 at that time to be obtained as the color data of the current test section.

[0152] This method can effectively obtain the color data of the middle of each segment to be measured, avoiding using the color data of the partition as the color data of the segment to be measured, and the measurement result is highly accurate.

[0153] In some embodiments, as Figure 3As shown, the detection unit 12 includes a light source 41 and a receiving element 42 disposed in the housing 11. The light source 41 is used to emit incident light that can illuminate a portion of the test sample 21. The preset position is located at one end of the housing 11 along the third direction. The receiving element 42 is located at the other end of the housing 11 along the third direction to receive reflected light formed by the portion of the test sample 21 located at the preset position reflecting the incident light. The reflected light is used to obtain colorimetric data, and the third direction is perpendicular to the first direction.

[0154] According to the embodiment of the present disclosure, it should be noted that: the first direction can be Figure 3 The direction perpendicular to the paper, the second direction is Figure 3 The left and right directions in the Figure 3 The up and down directions in .

[0155] The light source 41 can be arranged inside the housing 11, or outside the housing 11, irradiating incident light from the outside of the housing 11 to the inside of the housing 11. The light source 41 can be any device that emits light source 41 in the relevant technology, and the number of light sources 41 can be selected and adjusted as needed. Figure 3 As shown, the light source 41 includes two light-emitting elements.

[0156] The incident light emitted by the light source 41 can illuminate the sample to be tested 21 located at least at a preset position, and the incident light can be reflected by the sample to be tested 21 to form reflected light. The preset position and the receiving element 42 can be located at different spaces in the vertical direction within the shell 11, so that the receiving element 42 can receive the reflected light of the sample to be tested 21 at the preset position.

[0157] The receiving element 42 can obtain chromaticity data based on the received reflected light, thereby obtaining the chromaticity data of the sample to be tested 21 (the current segment to be tested) at the preset position, and can compare the chromaticity data with the preset standard chromaticity data to obtain a measurement result, thereby determining the chromaticity level of the portion of the sample to be tested 21. Since the sample to be tested 21 can move relative to the housing 11, multiple segments to be tested can pass through the preset positions, so the chromaticity data of multiple segments to be tested can be obtained through the receiving element 42, and the chromaticity data of the complete sample to be tested 21 can be detected. Of course, the receiving element 42 can only be responsible for receiving the reflected light to obtain the chromaticity data. The receiving element 42 can send the chromaticity data to a remote device, and the remote device can analyze the chromaticity data.

[0158] According to the embodiment of the present disclosure, the colorimetric data can be measured by the light source 41 and the receiving element 42, thereby determining the colorimetric level.

[0159] In some embodiments, as Figure 3As shown, the inner surface of the housing 11 is a spherical surface 43, and the inner surface of the housing 11 has a diffuse reflection layer. The light source 41 includes a first light-emitting element 44 and a second light-emitting element 45. The light emitted by the first light-emitting element 44 is irradiated onto the diffuse reflection layer to form a first sub-incident light that irradiates a portion of the test sample 21. The second light-emitting element 45 is used to emit a second sub-incident light that can illuminate a portion of the test sample 21. The first sub-incident light is full-spectrum light, and the second sub-incident light is short-wave light. The incident light includes the first sub-incident light and the second sub-incident light.

[0160] According to the embodiments of the present disclosure, it should be noted that:

[0161] Housing 11 may be an integrating sphere structure, having a spherical cavity within it. Test sample 21 may be located within spherical surface 43 of the spherical cavity. First and second light-emitting elements 44, 45 may be disposed outside spherical surface 43. Spherical surface 43 may be provided with a diffuse reflection layer, so that incident light striking spherical surface 43 is diffusely reflected, enabling colorimetric data detection. Light emitted by first and second light-emitting elements 44, 45 is diffusely reflected by spherical surface 43, thereby forming first and second incident sub-lights, respectively, that illuminate test sample 21 at a predetermined position.

[0162] The first light-emitting element 44 can emit full-spectrum light, which is diffusely reflected by the spherical surface 43 and then illuminates the test sample 21 at a predetermined position. The second light-emitting element 45 can emit short-wavelength light, which refers to light with a wavelength of 390nm-470nm. The short-wavelength light is diffusely reflected by the spherical surface 43 and then illuminates the test sample 21 at a predetermined position. The short-wavelength light provides a short-wavelength beam to supplement the energy of the short-wavelength portion of the full-spectrum light, thereby improving the accuracy of the test results.

[0163] In some embodiments, the first light-emitting element 44 includes a halogen lamp, and the second light-emitting element 45 includes a light-emitting diode (LED). The halogen lamp can emit full-spectrum light, and the light-emitting diode can emit short-wave light. The LED can provide a short-wave wavelength light beam to supplement the energy of the halogen lamp in the short-wave part, thereby improving the accuracy of the detection results.

[0164] The first light emitting element 44 and the second light emitting element 45 can be disposed outside the housing 11. In some embodiments, such as Figure 3As shown, the first light-emitting element 44 and the second light-emitting element 45 are located on both sides of the housing 11 along the second direction, and the housing 11 has a first light-emitting hole 47 and a second light-emitting hole 48. Light emitted by the first light-emitting element 44 is irradiated into the housing 11 through the first light-emitting hole 47, and light emitted by the second light-emitting element 45 is irradiated into the housing 11 through the second light-emitting hole 48. In this embodiment, the light emitted by the first light-emitting element 44 and the second light-emitting element 45 outside the housing 11 can enter the interior of the housing 11 through the first light-emitting hole 47 and the second light-emitting hole 48, thereby improving the color detection environment for the sample 21 to be tested at the preset position.

[0165] Since the second light emitting element 45 emits short-wave light, in order to prevent the short-wave light from directly irradiating part of the sample 21 to be tested and affecting the accuracy of the color measurement of the sample 21 to be tested, in some embodiments, Figure 3 As shown, a baffle 46 is further provided on the inner surface of the housing 11 , and the baffle 46 is used to reflect the light emitted by the second light emitting element 45 to prevent the light emitted by the second light emitting element 45 from directly irradiating a part of the sample 21 to be tested.

[0166] The inner surface of the shell 11 may have a baffle 46, which may be close to the second light output hole 48. The baffle 46 can reflect the short-wave light emitted by the second light-emitting element 45, thereby preventing the short-wave light from directly irradiating part of the test sample 21, thereby improving the accuracy of the color measurement of the test sample 21.

[0167] According to the embodiment of the present disclosure, full-spectrum light and short-wave light can be irradiated on the sample to be tested 21 at a preset position through the first light-emitting element 44 and the second light-emitting element 45, so that the sample to be tested 21 can be placed in a full-spectrum illumination environment, thereby improving the accuracy of color measurement of the sample to be tested 21.

[0168] In some embodiments, as Figure 3 As shown, a camera 49 is further provided in the housing 11 , and the camera 49 is used to capture an image of a portion of the test sample 21 located at a preset position.

[0169] It can be understood that the shooting camera 49 can be directed to a preset position to capture an image of the current segment to be tested, so that the chromaticity data can be bound to the image of the segment to be tested, which is convenient for verifying whether the chromaticity data corresponds to the segment to be tested, and avoiding the chromaticity data corresponding to the partition and affecting the grading result.

[0170] In the description of this specification, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.

For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections, or communication; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0173] In the present disclosure, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
