[0002] Fabric printing and dyeing color difference detection is a very important link in the textile printing and dyeing industry, involving the detection and quality control of fabric color difference; color difference is one of the key indicators to measure the quality of textiles. Through accurate color difference detection, the consistency of product color can be ensured to meet customer quality requirements. At the same time, through real-time monitoring of color difference, timely adjustments can be made during the production process to avoid large-scale production of unqualified products, thereby reducing material waste and production costs. In addition, color difference detection capabilities can help companies quickly respond to market changes and meet consumers' demand for personalized and customized products.

The motor 16 can drive the driven gear ring 18 to rotate through the meshing of the driving gear 17, and the driven gear ring 18 drives the turntable 10 to rotate at the same time; It is placed on the actuator together with the clamping assembly, that is, the sleeves 7 are matched with the insertion rods 15 one by one; then the motor 16 is driven, and the turntable 10 drives the extrusion plate 11 to rotate and squeeze one end of the expansion plate 12. One end of the expansion plate 12 is in an arc shape. At the same time, the expansion plate 12 is constrained by the U-shaped guide plate 14, so that the expansion plate 12 moves outward in a straight line. The expansion plate 12 drives the bottom plate 8 to move relatively away through the insertion rod 15. The bottom plate 8 drives the support plate 30 to move outward through the sleeve 7. The support plate 30 pulls and tightens the sample, so that the edges and corners of the sample are evenly subjected to the pulling force, thereby ensuring the flatness of the sample surface.

[0051] Reference Figure 1-Figure 12 The material lifting assembly includes a column 19, which is mounted on the turntable 10. A supporting plate 20 is provided at the upper end of the column 19. A vertical rod 21 is provided at the corner of the upper surface of the supporting plate 20. A rectangular frame 22 is fixedly connected to the upper end of the vertical rod 21. The frame opening of the rectangular frame 22 is opposite to the detection end of the detector 2, and the rectangular frame 22 can lift the woven material.

[0052] The axis position of the turntable 10 is provided with a through hole 23, and a column 19 is inserted into the through hole 23; an arc groove 24 is provided on the inner wall of the through hole 23; a sliding pin 25 is provided on the outer ring of the column 19, and the sliding pin 25 is slidably connected in the arc groove 24; the lower end of the column 19 passes through the bottom of the operating table 1, and the lower end of the column 19 is connected to the lower surface of the operating table 1 through a compression spring 26; the sliding pin 25 provided on the outer surface of the column 19 is slidably connected in the arc groove 24, and when the turntable 10 rotates The arc groove 24 will squeeze the sliding pin 25 to move upward, and at the same time, the sliding pin 25 drives the column 19 to move upward.

[0053] Reference Figure 3 and Fig.13 A fill light 27 is provided on the upper surface of the carrier plate 20; the fill light 27 is used to illuminate the sample to improve the clarity of sample observation, that is, before detection, turn on the fill light 27 to illuminate the sample to observe whether there are defects such as gaps 28 or holes on the sample. If there are problems, the sample can be removed immediately to avoid the detection end of the detector 2 facing the gap 28 or the hole during subsequent detection, resulting in invalid detection. If there is no defect after irradiation and observation, turn off the fill light 27 and then perform sample color difference detection.

[0054] Reference Figure 2 A strip-shaped notch 28 is provided on one side of the operating table 1, and a bracket assembly is installed in the notch 28. The bracket unit includes a cylinder 29. The output end of the cylinder 29 is horizontally executed in the outer direction of the operating table 1. The output end of the cylinder 29 is fixedly connected to an L-shaped support plate 30.

The detector 2 is installed on the operating table 1 through the bracket assembly, that is, the detector 2 is set above the sample by the cylinder 29 and the support plate 30. When the sample is loaded, the output end of the cylinder 29 drives the support plate 30 to move to the outside of the operating table 1, and the support plate 30 drives the detector 2 away from the center of the operating table 1. After the loading is completed, the output end of the cylinder 29 is reset, and the detector 2 is driven to move to the top of the sample, specifically to the position just above the frame opening of the rectangular frame 22, and then the color difference detection is performed; after the detection is completed, the output end of the cylinder 29 drives the detector 2 away from the center of the operating table 1 again, and the sample is removed together with the clamping assembly.

[0055] Reference Figure 4 and Fig.15Each of the clamping plates 3 is also provided with an isosceles trapezoidal extrusion groove 31 on the upper surface. The extrusion groove 31 is arranged to overlap with the groove 4, and an isosceles trapezoidal extrusion block 32 is arranged in each extrusion groove 31. The two opposite extrusion blocks 32 are connected together by an elastic rope 33. Considering the different thicknesses of the samples, the clamping portion 5 cooperates with the groove 4 to squeeze the thicker samples onto the clamping plate 3. However, for thinner samples, it is difficult for the clamping portion 5 to provide stable clamping for the samples. For this reason, an extrusion block 32 is provided. The shape of the extrusion block 32 and the extrusion groove 31 is set. When the two adjacent clamping plates 3 are relatively far away from each other, the elastic rope 33 pulls the extrusion block 32, and the extrusion block 32 squeezes the thinner sample into the extrusion groove 31, so that the sample can be firmly squeezed onto the clamping plate 3, thereby ensuring the stability of the sample after being pulled and straightened.

[0057] Reference Fig.10 A rotating groove is provided at the end of each of the extrusion plates 11, and a roller body 35 is rotatably connected in the rotating groove. The roller body 35 can be attached to and rotated in the arc-shaped opening 13; a roller body 35 is arranged at the end of the extrusion plate 11 to convert the sliding friction between the extrusion plate 11 and the arc-shaped opening 13 into rolling friction between the roller body 35 and the arc-shaped opening 13, thereby reducing friction, improving the smoothness of movement of the expansion plate 12, and facilitating the smooth pulling and tightening of the sample.

[0058] Reference Figure 4 A notch 36 is provided on the outer side wall of the end of each of the clamping plates 3; the notch 36 is provided on the clamping plate 3, and when the cover plate 6 is buckled off from the clamping plate 3, a finger is placed in the notch 36 and the lower surface of the cover plate 6 is pulled up to achieve the removal of the cover plate 6, which is convenient for the inspection personnel to operate.

[0059] Working principle: In this embodiment, the designed woven fabric printing and dyeing difference detection device is aimed at the printing and dyeing difference detection of woven fabrics with uneven wrinkles; the woven fabric material to be detected, that is, the sample, is clamped on the fixed column by the clamping component, and then the clamping component and the sample are installed on the execution component, and then the sample is pulled and tightened by the operation of the execution component, so that the surface of the sample is in a flat state, and at the same time, the pushing component is used to push the sample and push the sample toward the detection unit. At this time, the sample is pulled and tightened again, that is, a part of the sample is placed on the detection end face of the detector 2, so that the sample can be closely attached to the detection end face of the detector 2, thereby ensuring the accuracy of the sample color difference detection;

[0060] In the embodiment, the woven material to be tested is the sample to be tested. The sample sent by the manufacturer can be round or rectangular. There are multiple clamping components, and each clamping component is laid with the sample to be tested. The sample is prepared in advance to facilitate subsequent testing and improve the testing efficiency. The edge of the sample is placed on the clamping plate 3, and then the cover plate 6 is installed on the clamping plate 3. At the same time, the clamping part 5 squeezes the sample into the groove 4. At this time, the sample is initially placed and waits to be loaded onto the execution component. The execution component can quickly realize the tightening and straightening of the sample.

[0061] In this embodiment, the driving assembly designed includes a motor 16, the output end of the motor 16 is fixedly connected to a driving gear 17, the driving gear 17 is meshed with a driven gear ring 18, and the driven gear ring 18 is sleeved on the outer ring of the lower half of the turntable 10. The motor 16 can drive the driven gear ring 18 to rotate through the meshing of the driving gear 17, and the driven gear ring 18 drives the turntable 10 to rotate; the sample is placed on the execution assembly together with the clamping assembly, that is, the sleeves 7 are matched with the insertion rods 15 one by one; then the motor 1 is driven 6. The turntable 10 drives the extrusion plate 11 to rotate and squeezes one end of the expansion plate 12. One end of the expansion plate 12 is in an arc shape. At the same time, the expansion plate 12 is constrained by the U-shaped guide plate 14, so that the expansion plate 12 moves outward in a straight line. The expansion plate 12 drives the bottom plate 8 to move away relatively through the insertion rod 15. The bottom plate 8 drives the support plate 30 to move outward through the sleeve 7. The support plate 30 pulls and tightens the sample, so that the corners of the sample are evenly subjected to the pulling force to ensure the flatness of the sample surface;

[0062] The sliding pin 25 provided on the outer surface of the column 19 is slidably connected in the arc groove 24. When the turntable 10 rotates, the arc groove 24 will squeeze the sliding pin 25 to move upward, and at the same time, the sliding pin 25 drives the column 19 to move upward. The column 19 pushes the rectangular frame 22 through the vertical rod 21, and the rectangular frame 22 pushes the sample, and the middle area of ​​the sample is pushed on the detection end surface of the detector 2. At the same time, during the pushing process of the rectangular frame 22, the rectangular frame 22 will also squeeze the sample, thereby improving the flatness of the area to be detected on the sample, which helps to improve the tightness of the sample and the detection end of the detector 2, thereby improving the accuracy of sample color difference detection;

[0063] The supplementary light 27 is used to illuminate the sample to improve the clarity of sample observation. That is, before the test, turn on the supplementary light 27 to illuminate the sample to observe whether there are defects such as notches 28 or holes on the sample. If there are problems, the sample can be removed immediately to avoid the detection end of the detector 2 facing the notch 28 or hole during subsequent testing, resulting in invalid testing. After irradiation and observation, if there is no defect, turn off the supplementary light 27 and then perform sample color difference detection.

[0064] The detector 2 is installed on the operating table 1 through a bracket assembly, that is, the detector 2 is set above the sample by means of a cylinder 29 cooperating with a support plate 30. When the sample is loaded, the output end of the cylinder 29 drives the support plate 30 to move to the outside of the operating table 1, and the support plate 30 drives the detector 2 away from the center of the operating table 1; after the loading is completed, the output end of the cylinder 29 is reset, and drives the detector 2 to move above the sample, specifically to the position just above the frame opening of the rectangular frame 22, and then performs color difference detection; after the detection is completed, the output end of the cylinder 29 drives the detector 2 away from the center of the operating table 1 again, and the sample is removed together with the clamping assembly;

[0065] Considering that the thickness of the samples varies, the clamping portion 5 cooperates with the groove 4 to squeeze the thicker sample onto the clamping plate 3. However, for the thinner sample, the clamping portion 5 is difficult to provide stable clamping for the sample. For this reason, a squeezing block 32 is provided. The squeezing block 32 and the squeezing groove 31 are arranged in a shape. When two adjacent clamping plates 3 are relatively far away from each other, the elastic rope 33 pulls the squeezing block 32, and the squeezing block 32 squeezes the thinner sample into the squeezing groove 31, so that the sample can be firmly squeezed onto the clamping plate 3, thereby ensuring the stability of the sample after being pulled and straightened.

[0066] The supporting plate 20 is rotatably connected to the column 19. When the rectangular frame 22 is pressed against the lower surface of the sample, the spikes 34 are inserted into the sample to fix the sample in the inner circle of the rectangular frame 22, so that the sample is stabilized on the rectangular frame 22 and will not be wrinkled or deformed due to accidental loosening of the clamping assembly, thereby ensuring the stability of the sample.

[0067] A roller body 35 is provided at the end of the extrusion plate 11 to convert the sliding friction between the extrusion plate 11 and the arc-shaped opening 13 into rolling friction between the roller body 35 and the arc-shaped opening 13, thereby reducing friction, improving the smoothness of movement of the expansion plate 12, and facilitating the smooth pulling and tightening of the sample;

[0068] A notch 36 is provided on the outer side wall of the end of each of the clamping plates 3; the notch 36 is provided on the clamping plate 3, and when the cover plate 6 is buckled off the clamping plate 3, a finger is placed in the notch 36 and the lower surface of the cover plate 6 is pulled up to achieve the removal of the cover plate 6, which is convenient for the inspection personnel to operate.
