[0055] The working principle of the present application is as follows:

[0056] In operation, the support frame 1 serves as an overall support structure, and the several tension rollers 3 movably connected in the center of the inside first realize the transmission and tension of the color-woven fabric. The color-woven fabric is transmitted to the fixed pressing wire assembly 4 at the top of the support frame 1, and the pressing wire assembly 4 cooperates with the color-woven fabric to complete the process of interweaving into fabric. At the same time, the tension assembly 5 movably connected on the outside of the pressing wire assembly 4 dynamically adjusts the tension of the color-woven fabric through the elastic expansion cooperation of the bandage 6 movably connected on the outer surface, so as to ensure that the fabric tension is uniform and stable during weaving.

[0057] While the tension rollers 3 are rotating to transmit the color-woven fabric, the dust removal device 2 connected on the bottom of the inside of the support frame 1 starts the automatic cleaning operation;

[0058] The two drive devices 22 movably connected on the top of the first sliding rod 21 in the dust removal device 2 start to operate. The drive device 22 includes a motor 222, and the push column 223 movably connected on the output shaft end of the motor 222 drives the L-shaped plate 224 fixedly connected on the top to realize the reciprocating movement in the horizontal direction. Since the rear end of the L-shaped plate 224 is fixedly connected with the front end of the first sliding block 225, the first sliding block 225 is driven to move synchronously.

[0059] Since the rear end groove of the first sliding block 225 slides along the outer surface of the second sliding rod 226 in the horizontal direction, the second sliding rod 226 plays a guiding and stabilizing role, avoiding the deviation or jamming of the first sliding block 225. At the same time, the telescopic rod 227 fixedly connected on the inside of the first sliding block 225 drives the second sliding block 228 fixedly connected on the bottom to adjust the width through the telescopic action, so that the support device 23 fixedly connected on the top of the first sliding block 225 and the second sliding block 228 realizes the position linkage adjustment.

[0060] The support device 23 includes a pneumatic cylinder 231, which drives the oval bottom plate 232 fixedly connected on the output shaft end to move up and down, and drives the four supports 233 and the first connecting plate 234 fixedly connected on the top of the supports 233 to move up synchronously, so that the cleaning device 24 connected on the top of the first connecting plate 234 approaches the outer surface of the tension roller 3, providing the basic position condition for the cleaning operation.

[0061] Subsequently, the drive block 235 fixedly connected on the bottom center of the first connecting plate 234 is started, and drives the threaded rod 236 movably connected on the output shaft end of the bottom to rotate. The rotated threaded rod 236 drives the second connecting plate 237 movably connected on the outer surface to move downward along the axial direction, and the second connecting plate 237 also slides along the outer surface of the four supports 233 as a guide, so that the cleaning device 24 can expand outward.

[0062] The four first rotating shafts 241 in the cleaning device 24 are movably connected with the top protruding part of the second connecting plate 237, so they will drive the center movably connected movable rod 242 to produce a linkage action when the second connecting plate 237 moves downward synchronously, when the bottom of the movable rod 242 is stretched, the top movably connected second rotating shaft 243 makes the two ends movably connected swing block 244 bottom one end offset to one side, while the swing block 244 bottom the other end protruding part is movably connected with the top protruding part of the first connecting plate 234, and is limited to rotate and adjust around the connecting point, through this compound motion, the swing block 244 top and the two sides bevel movably connected first cleaning assembly 245 and second cleaning assembly 246 expand or fit in different directions, cooperate with the reciprocating sliding and width adjustment of the supporting device 23 driven by the driving device 22, to clean the dust and fiber impurities remaining on the surface of the tensioning roller 3, keep the roller surface clean, reduce the pollution to the yarn-dyed fabric and prolong the service life of the tensioning roller 3.

[0063] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, the scope of the present application being defined by the appended claims and their equivalents.
