Through the adjustable design of the limit plate, cloth rolls of different widths and diameters can be limited, ensuring that the cloth rolls can remain stable and will not shift forward and backward during cloth inspection, thereby ensuring that the cloth can be stably spread out during cloth inspection, facilitating cloth inspection, and ensuring the stability of the cloth inspection machine during use; the structure of the application is reasonable, the cloth can be cut by the cutting blade, and through the movable design between the support rod and the machine body, the position of the support rod can be adjusted by twisting the fixed block, ensuring that the support rod will not affect the normal cloth inspection of the machine body, thereby improving the practicality of the cloth inspection machine.

[0004] With respect to the above-mentioned related contents, the following technical defects exist: the cutting and inspecting machine for fabrics is a device for inspecting and cutting fabrics. By placing a roller wrapped with fabric on the power device of the cutting and inspecting machine for fabrics, the power device can be controlled by the regulating device of the cutting and inspecting machine for driving and driving the fabric roller for rotation, so that one end of the fabric is in contact with the surface of the cutting and inspecting machine body, thereby enabling the cutting and inspecting machine to cut and inspect the fabrics. However, when the fabric slides on the cutting and inspecting machine for fabrics, the surface of the fabric will be offset on the cutting and inspecting machine body because the surface is too smooth, resulting in deviations in the inspection of the fabric by the cutting and inspecting machine for fabrics, and the subsequent cutting effects will also be deviated, affecting the size of the fabric cut by the cutting and inspecting machine for fabrics, resulting in the need to rework this batch of fabrics, seriously affecting the progress of the cutting and inspecting work for fabrics.

[0005] Therefore, it is necessary to provide a new kind of weaving cutting and inspecting machine to solve the problems of the technologies described above. Utility Model Content

[0034] The working principle of a textile cutting and inspecting machine provided by the utility model is as follows: when it is necessary to limit the movement of the cloth on the cutting and inspecting machine body 1, the fixed plate 201 is installed on the power device 5 through the screw rod 202, and the motor 203 installed on the fixed plate 201 can be started at this time. The movement of the motor 203 will drive the adjusting block 205 to move along the direction of the sliding rod 206 through the screw rod 204. At this time, the position of the limit plate 209 can be adjusted by the motor 203, so that the limit plate 209 can better cope with cloth of different sizes. After the limit plate 209 is adjusted to a suitable position, the side of the cloth can be placed in the contact plate 208 and the limit plate 209. At this time, the rotating rod 211 can be rotated, and the rotation of the rotating rod 211 will drive the limit plate 209 to move through the sliding block 210, so that the limit plate 209 can move in the direction of the contact plate 208 to limit the movement angle of the side of the cloth, thereby limiting the movement of the cloth.

[0035] When it is necessary to clean the surface of the cloth to be cut and inspected, the cloth is placed between the two cleaning plates 33. At this time, one of the cleaning plates 33 can be pressed in the direction of the other cleaning plate 33. At this time, the movement of the cleaning plate 33 will drive the spring 35 to stretch through the round rod 34, and the cleaning plates 33 can be pressed so that both cleaning plates 33 are in contact with the cloth. At this time, the insertion rod 37 can be inserted into one of the inner walls of the fixing block 36. The insertion of the insertion rod 37 will contact the inner wall of the cleaning plate 33 through the fixing block 36, so that the angle of the cleaning plate 33 can be fixed by the insertion rod 37, and the insertion rod 37 will also be adsorbed by the magnetic ring 38 on the inner wall of the fixing block 36. Therefore, the stability of fixing the angle of the cleaning plate 33 can be improved by the adsorption of the insertion rod 37 and the magnetic ring 38.
