[0039] The widening mechanism 200 includes a widening frame 201, on which a plurality of cloth conveying rollers 202 are arranged, and between the plurality of cloth conveying rollers 202, widening rollers 203 are arranged;

[0040] The expansion roller 203 is an arched structure;

[0041] Working principle:

[0042] When the width of the cord fabric is expanded, the cord fabric first passes through the deviation correcting mechanism 100, then passes through the width expanding mechanism 200, and finally passes through the width fixing mechanism 300, thereby completing the width expansion of the cord fabric.

[0043] When the tire cord fabric passes through the deflection correction mechanism 100, it always remains in the middle of the first deflection correction roller 102.6 and the second deflection correction roller 102.7, avoiding the problem of incorrect position when the tire cord fabric is expanded. If the tire cord fabric is positioned toward one end of the roller, the servo motor 103 in the deflection correction mechanism 100 will appropriately adjust the position of the slider 102.4 on the slide bar 102.3, and the slider 102.4 will slide on the slide bar 102.3, thereby driving the slider 102.4 at the other end to slide on the slide bar 102.3; at the same time, due to the rotational cooperation between the deflection correction roller seat 102.5 and the slider 102.4, the deflection correction roller seat 102.5 will also rotate on the slider 102.4, and finally the tire cord fabric is adjusted to the middle of the first deflection correction roller 102.6 and the second deflection correction roller 102.7 while ensuring that its tension remains unchanged, making sufficient preparations for the subsequent expansion;

[0044] After the correction of the deviation by the correction mechanism 100 is completed, the cord fabric is expanded. During the expansion, the cord fabric enters the expansion mechanism 200 and is expanded by the expansion roller 203. During the expansion, the cord fabric on the expansion roller 203 must be in the middle, otherwise the cord fabric after the expansion will have a weft skew phenomenon.

[0045] After the width expansion, the cord fabric needs to pass through the width fixing mechanism 300 to ensure the effect of the width expansion. In the width fixing mechanism 300, the two sides of the cord fabric are clamped between the upper width fixing rod 302.10 and the lower width fixing rod 302.7 to prevent the cord fabric from shrinking after the width expansion. The positions of the two width fixing components 302 in the width fixing mechanism 300 can be adjusted separately. When adjusting the width fixing component 302, it is only necessary to adjust the rotating handle 302.21 to make the width fixing component 302 move to the corresponding position along the screw rod 302.2, so as to maximize the effect of the width fixing mechanism 300. The angle between the whole composed of the upper fixing rod 302.10 and the lower fixing rod 302.7 and the horizontal plane can be adjusted. The specific adjustment method is: when the whole composed of the upper fixing rod 302.10 and the lower fixing rod 302.7 cannot fix the amplitude well due to the inappropriate angle, the angle adjustment motor 303.1 will act on the end of the connecting member horizontal section 302.14 on the upper connecting member 302.13, and the upper connecting member 302.13 will rotate a certain angle along its middle. At this time, the upper fixing rod 302.10 rotatingly matched on the connecting member vertical section 302.15 will rotate the same angle. Since the lower fixing rod 302.7 and the upper fixing rod 302.10 are fixed together, the two lower fixing rods 302.7 will rotate a certain angle around their corresponding lower fixing rod fixing seats 302.6, and finally reach a suitable fixing angle.
