[0029] Specifically, during the process of detecting the color difference of the fabric, the fabric is detected in the protection box 2. The protection box 2 is used to block the influence of stray light in the environment on the detection. The cleaning brush 402 in the cleaning mechanism 4 is placed on the top of the fabric. The counterweight 404 is used to increase the counterweight, and the cleaning brush 402 is pressed on the top of the fabric. The counterweight is adjusted by increasing or decreasing the number of the counterweight 404. When the fabric is relatively light, the number of the counterweight 404 is reduced to avoid damage to the fabric due to a large counterweight. When the fabric is relatively thick, the number of the counterweight 404 is increased to provide sufficient cleaning force, which helps to clean foreign matter on the surface of the fabric more deeply. During the movement and rotation of the fabric, the cleaning brush 402 is used to clean foreign matter on the surface of the fabric to avoid foreign matter. The existence of causes obstruction, affecting the color difference detection of the cloth. At the same time, the adapter 401 rotates around the end of the connecting rod 405, and the top of the connecting rod 405 rotates around the base 406, thereby adjusting the cleaning surface of the cleaning brush 402 to ensure that the cleaning brush 402 always fits the surface of the cloth, avoiding the cleaning brush 402 from being loosely fitted to the surface of the cloth, affecting the cleaning effect. At the same time, the foreign matter to be cleaned is collected by the collecting mechanism 3 to avoid foreign matter accumulation, and then the color difference detection of the cloth is performed through the color difference detector body 10. The model of the color difference detector body 10 is Ci7860, which is convenient for eliminating detection interference and improving detection accuracy. After completing the color difference detection, the cloth is re-rolled up by the winding mechanism 5, which is convenient for arranging the cloth that has completed the color difference detection.

[0030] Please refer to Figure 3 , Figure 4 and Figure 6 The collecting mechanism 3 includes a dust collector head 301, and hoses 302 are fixedly installed at the front and rear ends of the top of the dust collector head 301. The same dust collection box 303 is fixedly installed on the tops of the two hoses 302. Dust collection fans 305 are installed at the front and rear ends of the tops of the dust collection box 303, and a dust filter plate 306 is clamped on one side of the dust collection box 303.

[0031] Specifically, after the dust suction fan 305 is started, a negative pressure is formed inside the dust suction box 303, and the foreign matter cleaned by the cleaning brush 402 is sucked into the dust suction box 303 through the hose 302 and the dust suction head 301, and the foreign matter is filtered by the dust filter plate 306 to be retained on the dust filter plate 306, so as to facilitate the collection of the cleaned foreign matter and avoid the accumulation of foreign matter.

[0032] Please refer to Figure 1 , Figure 3 and Figure 4 The dust collector head 301 is fixedly connected to the adapter 401, the dust collector box 303 is fixedly connected to the protective box 2 by bolts, the dust collection port on the dust collector head 301 is inclined toward the cleaning brush 402, and the collection mechanism 3 also includes rollers 304 movably installed on both sides of the bottom of the dust collector head 301.

[0033] Specifically, after the cleaning brush 402 cleans the cloth, the cleaned foreign matter is sucked into the dust collector head 301 to prevent the accumulation of foreign matter. When the counterweight block 404 presses down the adapter 401, the dust collector head 301 is pressed down along with the adapter 401, and the roller 304 contacts the cloth to reduce the friction force on the cloth, thereby preventing the bottom of the dust collector head 301 from directly contacting the cloth, causing the cloth to be scratched due to excessive friction when the cloth moves.

[0034] Please refer to Figure 7 The winding mechanism 5 includes a winding roller 501, and transfer grooves 502 are provided at both ends of the winding roller 501. Transfer shafts 503 are provided at both ends of the winding roller 501. A fixing bolt 504 is provided at the top of the transfer shaft 503. The transfer shaft 503 is fixedly connected to the winding roller 501 through the fixing bolt 504 and the transfer groove 502.

[0035] Specifically, when the cloth is undergoing color difference detection, the cloth that has completed the detection is rolled up onto the winding roller 501. After removing the fixing bolt 504, it is convenient to remove the winding roller 501 from the transfer shaft 503, so as to facilitate the arrangement of the cloth that has completed the color difference detection.

[0036] Please refer to Figure 1 and Figure 7The outer ring of the transfer shaft 503 is installed with a bearing 505, and the transfer shaft 503 is movably connected to the detection platform 1 through the bearing 505. A stepper motor 506 is installed at one end of one of the transfer shafts 503, and the base of the stepper motor 506 is fixedly connected to the detection platform 1.

[0037] Specifically, after the stepper motor 506 is started, it drives the transfer shaft 503 to rotate, and then the rotation of the transfer shaft 503 drives the winding roller 501 to rotate, so as to roll up the cloth after the color difference detection is completed.

[0038] Please refer to Figure 2 and Figure 8 The bottom of the protective box 2 is movably equipped with upper pressure rollers 13 on both sides, and the top of the detection platform 1 and directly below the upper pressure roller 13 is equipped with a lower support mechanism 14, the lower support mechanism 14 includes two roller frames 1401 arranged parallel to each other, and a spring 1402 is fixedly installed at the bottom of the roller frames 1401. The bottom of the two roller frames 1401 is fixedly equipped with a spring 1402, and the roller frames 1401 are slidably connected to the detection platform 1.

[0039] Specifically, during the process of detecting the color difference of the cloth, the cloth is pressed against the top of the lower pressure roller 1403 by the upper pressure roller 13, and the lower pressure roller 1403 is easily raised and lowered by the spring 1402 in cooperation with the roller frame 1401, so as to adjust the distance between the upper pressure roller 13 and the lower pressure roller 1403, and facilitate the installation of the upper pressure roller 13 and the lower pressure roller 1403 to adapt to cloths of different thicknesses.

[0040] Please refer to Figure 2 , Fig. 9 , Fig.10 and Fig.11 A crossbeam 11 is fixedly installed between the front and rear end inner walls of the protective box 2 and on both sides of the color difference detector body 10. A marking mechanism 12 is installed at the bottom of the crossbeam 11. The marking mechanism 12 includes an adapter plate 1201, which is fixedly connected to the crossbeam 11 by bolts. A carrying plate 1202 is fixedly installed on both sides of the bottom of the adapter plate 1201. A marking roller 1210 is arranged at the rear end between the two carrying plates 1202. A fixing bolt 1203 is threadedly connected through one side of one of the carrying plates 1202 and corresponding to the position of the marking roller 1210. The marking roller 1210 is sleeved with the fixing bolt 1203. A winding roller 1205 is movably installed between the two carrying plates 1202 near the front end. A stepper motor 1204 is fixedly installed through one side of one of the carrying plates 1202. The output shaft of the stepper motor 1204 is fixedly connected to the winding roller 1205.

[0041] Specifically, after removing the fixing bolt 1203, remove the label roller 1210 and wind the rolled label around the outside of the label roller 1210. A single label is divided into two parts: a base material and a surface material. The base material is arranged in a "U" shape and the surface material is arranged in a rectangular shape. The surface material is located at the center of the base material and a single-sided adhesive is arranged on the bottom of the surface material. Then, reinstall the label roller 1210 between the two mounting plates 1202, pull out a part of the label and wind it around the winding roller 1205. When the stepper motor 1204 is started, it drives the winding roller 1205 to rotate to wind up the base material in the label after marking, and pulls the label to move, which is convenient for releasing the label and moving the unused surface material in the label to the top of the fabric.

[0042] Please refer to Fig.10 and Fig.11 The marking mechanism 12 also includes a bottom frame 1208 fixedly installed between the two carrying plates 1202 near the bottom end, and guide rollers 1209 are movably installed between the two carrying plates 1202 and at the front and rear ends of the bottom frame 1208.

[0043] Specifically, when the label is installed between the two mounting plates 1202, the label passes over the bottom of the two guide rollers 1209 and is then wound around the second winding roller 1205. When the label moves, the guide rollers 1209 are provided to prevent the label from contacting the corners of the bottom frame 1208, thereby reducing the friction on the label and preventing the label from breaking due to excessive friction during movement.

[0044] Please refer to Fig.10 and Fig.11 The marking mechanism 12 also includes an electric telescopic rod 1206 fixedly installed between the two mounting plates 1202 and in the center. A marking block 1207 is fixedly installed at the bottom of the piston rod of the electric telescopic rod 1206, and the marking block 1207 is slidably connected to the bottom frame 1208.

[0045] Specifically, after the electric telescopic rod 1206 is started, it drives the marking block 1207 to move downward, pushes out the surface material in the label, and presses it to the top of the cloth, and uses the single-sided adhesive at the bottom of the surface material to stick the surface material to the cloth, so as to facilitate marking the area with color difference on the cloth, and facilitate quickly locating the position of the color difference after completing the color difference detection of the cloth.

[0046] Please refer to Figure 1 Roller grooves 6 are provided on both sides of the top of the detection platform 1, two lower magnetic blocks 7 are fixedly installed on the front side of the detection platform 1 near the top, upper magnetic blocks 8 are installed on the front side of the protection box 2 near the bottom and on the top of the two lower magnetic blocks 7, and a handle 9 is fixedly installed in the center of the front side of the protection box 2.

[0047] Specifically, the uninspected cloth is set between the two roller grooves 6 on the side close to the collecting mechanism 3. The protective box 2 is opened by lifting the handle 9 to facilitate the setting of the cloth on the lower pressure roller 1403. When the protective box 2 is closed, the protective box 2 is limited by the mutual attraction between the upper magnetic block 8 and the lower magnetic block 7, which makes it convenient to fix the protective box 2 on the top of the detection platform 1 to prevent the protective box 2 from being pushed open due to the presence of the spring 1402.

[0048] How it works During the process of detecting the color difference of the cloth, the cloth is detected in the protection box 2. The protection box 2 is used to block the influence of stray light in the environment on the detection. The undetected cloth is set between the two roller grooves 6 on the side close to the collecting mechanism 3. The protection box 2 is opened by lifting the handle 9. One end of the cloth is pulled out and set on the lower pressure roller 1403. After passing directly under the color difference detector body 10, it is wound on the winding roller 501. The cleaning brush 402 in the cleaning mechanism 4 is placed on the top of the cloth. The counterweight is increased by the counterweight block 404, and the cleaning brush 402 is pressed on the top of the cloth. The number of counterweight blocks 404 is used to adjust the counterweight. When the fabric is relatively light, the number of counterweight blocks 404 is reduced to avoid damage to the fabric due to a large counterweight. When the fabric is relatively thick, the number of counterweight blocks 404 is increased to provide sufficient cleaning force, which helps to more deeply clean foreign matter on the fabric surface. After the stepper motor 506 is started, it drives the transfer shaft 503 to rotate, and then drives the winding roller 501 to rotate through the rotation of the transfer shaft 503, so as to facilitate the winding of the fabric after the color difference detection is completed. In the process of moving and rotating the fabric, foreign matter on the fabric surface is cleaned by the cleaning brush 402 to avoid foreign matter on the fabric surface. The existence of objects causes obstruction, affecting the color difference detection of the cloth. At the same time, the adapter 401 rotates around the end of the connecting rod 405, and the top of the connecting rod 405 rotates around the base 406, thereby adjusting the cleaning surface of the cleaning brush 402 to ensure that the cleaning brush 402 always fits the surface of the cloth, avoiding the cleaning brush 402 from being loosely fitted to the surface of the cloth, which affects the cleaning effect. At the same time, after the dust suction fan 305 is started, a negative pressure is formed inside the dust suction box 303, and the foreign matter cleaned by the cleaning brush 402 is sucked into the dust suction box 303 through the hose 302 and the dust suction head 301, and is passed through the dust filter plate 306. Filter and retain foreign matter on the dust filter plate 306, so as to collect the cleaned foreign matter and avoid the accumulation of foreign matter. Then, the color difference detection of the cloth is carried out through the color difference detector body 10, so as to eliminate the detection interference and improve the detection accuracy. After the detection is completed, if the cloth is detected to have color difference, the electric telescopic rod 1206 is started to drive the marking block 1207 to move downward, push out the surface material in the label, and press it to the top of the cloth. The single-sided adhesive at the bottom of the surface material is used to stick the surface material to the cloth, so as to mark the area with color difference on the cloth, and quickly locate the position of the color difference after the color difference detection of the cloth is completed.
