[0024] Embodiment 1:

[0025] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, a cloth stretching device for a cloth inspection machine comprises a cloth inspection machine body 1, on which a plurality of conveying rollers 2 are arranged, on which cloth 3 is stretched and conveyed, wherein a cloth stretching device 4 is arranged between two adjacent conveying rollers 2, and the cloth stretching device 4 comprises a transmission assembly 5 and a cloth stretching assembly 6 driven by the transmission assembly 5, the transmission assembly 5 is mounted on the cloth inspection machine body 1, and the power input end of the transmission assembly 5 is connected to the power output end of the motor, the cloth stretching assembly 6 is rotatably mounted on the cloth inspection machine body 1, and the cloth stretching assembly 6 is pressed against the lower surface of the cloth 3. The cloth stretching device 4 is located at the front section of the cloth inspection part of the cloth inspection machine body 1.

[0026] By means of the transmission assembly 5 and the cloth stretching assembly 6 driven by the transmission assembly 5, the bottom surface of the cloth is flattened to avoid the uneven surface of the cloth caused by the wrinkles of the cloth roll itself and the deviation of the cloth by the conveying roller when unrolling, thereby improving the inspection effect and accuracy of the cloth inspection machine.

[0027] Embodiment 2:

[0028] Based on the above embodiments, this embodiment Figure 2 As shown, the cloth stretching assembly 6 is composed of two cloth stretching rollers 7, which are symmetrically arranged and rotatably mounted on the cloth inspection machine body 1, and the two outer ends of the two cloth stretching rollers 7 extend out of the outside of the cloth 3. The inner ends of the two cloth stretching rollers 7 are feeding ends. The two cloth stretching rollers 7 are inclined, and the inner ends of the two cloth stretching rollers 7 are close to each other.

[0029] Along the advancing direction of the cloth 3 , the two cloth-stretching rollers 7 flatten the cloth 3 from the center line of the cloth 3 to both sides, and ensure that all the cloth 3 is stretched tightly by the cloth-stretching rollers 7 .

[0030] Embodiment three:

[0031] Based on the above embodiments, this embodiment Figure 3 As shown, the transmission assembly 5 includes a first bevel gear 8, a second bevel gear 9 and a circular gear 10.
