[0029] A telescopic component 512 is fixedly connected to the left front end of the mounting bracket 52. The telescopic component 512 consists of a mounting rod fixedly connected to the left front end of the mounting bracket 52 and an electromagnetic block slidably connected to the bottom of the mounting rod. The electromagnetic block is electrically connected to an external current transmitter. A movable plate 513 is fixedly connected to the bottom of the electromagnetic block inside the telescopic component 512.

[0032] The working principle of the automatic fabric correction and tension balancing mechanism of a fabric inspection machine based on Embodiment 1 is as follows:

[0033] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0034] Second, when it is necessary to correct the deviation of the fabric, the air gripper 4 is activated so that the air gripper 4 clamps the fabric, and then the first cylinder 3 is activated. The first cylinder 3 drives the fabric to move through the air gripper 4 to correct the deviation of the fabric.

[0035] Third, when periodic maintenance is required on the first cylinder 3 and the gripper 4, the external current output device stops the electromagnetic block inside the telescopic component 512. The operator then slides the electromagnetic block upwards. After the movement is complete, the external current output device activates the electromagnetic block inside the telescopic component 512, causing it to magnetically attach to the mounting rod inside the telescopic component 512. This causes the electromagnetic block to move the moving plate 513 upwards, which in turn moves the control switch 514 upwards, activating the first motor 54. 4 drives the turntable 55 to rotate. The turntable 55 drives the swing block 57 to swing to the lower left through the rotational connection with the first rotating rod 56. The swing block 57 drives the moving block 510 to move downward within the limit block 511 through the rotational connection with the second rotating rod 59. This causes the moving block 510 to press the control switch 514, thereby causing the control switch 514 to drive the timer 53 to work. The timer 53 then starts timing. When the timer 53 reaches the required time, the staff performs regular maintenance on the first cylinder 3 and the gripper 4 to improve the reliability of automatic correction.

[0036] Fourth, when it is necessary to blow dust off the pneumatic gripper 4, activate the two sets of one-way valves inside the transmission component 515. The operator delivers pure gas to the piston cylinder inside the transmission component 515 through the connecting pipe at the right end of the piston cylinder inside the transmission component 515. During the swinging process, the swing block 57 drives the connecting rod inside the transmission component 515 to rotate. The connecting rod inside the transmission component 515 drives the arc block inside the transmission component 515 to swing to the right. The arc block inside the transmission component 515 drives the moving rod inside the transmission component 515 to move downward through the limiting plate inside the transmission component 515 through the rotational connection setting. The moving rod inside the transmission component 515 drives the piston rod inside the transmission component 515 to move downward, so that the gas inside the piston cylinder inside the transmission component 515 is delivered to the outside through its bottom connecting pipe to blow dust off the pneumatic gripper 4 and prevent impurities from affecting the normal operation of the pneumatic gripper 4.

[0045] When tension balancing of the fabric is required, the electromagnetic block at the front end of the first lower pressure roller 66 is stopped by an external current output device. Then, the second motor 62 is started. The second motor 62 drives the single gear 610 to rotate, which in turn drives the grooved wheel 611 to rotate.
